Corrosion of reinforcing bars in concrete has a negative impact on the safety of reinforced concrete structures due to a decrease in internal load due to loss of cross-section of the reinforcing bars and a decrease in adhesion due to damage to the reinforcing bar joints.

Additionally, the volume of the rebar expands, and the expansion pressure causes stress in the surrounding concrete, causing cracks in the concrete covering. When a crack occurs, the supply of oxygen or moisture becomes easier, further accelerating corrosion of the rebar, so the crack progresses further. Additionally, as this process experiences freezing and thawing in the winter, the situation worsens, and the durability of the reinforced concrete structure is significantly reduced, including loss of covering concrete and poor aesthetics.

It has been found that an average annual maintenance cost of approximately 140 billion won is incurred due to deterioration and damage to port facilities, including corrosion of steel bars. Attempts to fundamentally solve the problem of corrosion of steel bars in steel-concrete structures have been made in Japan, Europe, Canada, and other countries.

Riva and its manufacturing device according to the first embodiment

Figure 1 is a diagram for explaining a fiber supply module, spreading module, impregnation tank, and collector among the riba manufacturing apparatus according to the first embodiment of the present invention, and Figure 2 is a riba manufacturing device according to the first embodiment of the present invention. It is a diagram for explaining a collector, a cooling module, and a prepreg tape manufacturing module among the devices, Figure 3 is a diagram for explaining a preforming module among the riba manufacturing devices according to the first embodiment of the present invention, and Figure 4 is a diagram for explaining the present invention. This is a diagram for explaining the riba manufacturing module among the riba manufacturing devices according to the first embodiment.

1 to 4, the riba manufacturing device according to the first embodiment includes a fiber supply module 310, a spreading module 320, an impregnation tank 330, a collector 340, and a cooling module 350. , it may include a prepreg tape manufacturing module 360, a preforming module 370, and a riba manufacturing module 380. Below, each configuration is explained.

Referring to FIG. 1, the fiber supply module 310 may include a plurality of bobbins (BN) that supply basalt fibers (BF). The plurality of basalt fibers (BF) unwound from the plurality of bobbins (BN) may be provided to the spreading module 320.

According to one embodiment, the spreading module 320 may include a first spreading module 322 and a second spreading module 324. The first and second spreading modules 322 and 324 may receive a plurality of basalt fibers (BF) provided from a plurality of bobbins (BN) and spread them laterally. Accordingly, a plurality of the basalt fibers (BF) may be aligned by the first and second spreading modules 322 and 324.

The first spreading module 322 and the second spreading module 324 may have different motor rotation speeds and friction rotation speeds. According to one embodiment, the motor rotation speed and friction rotation speed of the second spreading module 324 may be faster than the motor rotation speed and friction rotation speed of the first spreading module 322. For example, the motor rotation speed of the first spreading module 322 may be 90 rpm and the friction rotation speed may be 70 rpm. In contrast, the motor rotation speed of the second spreading module 324 may be 110 rpm and the friction rotation speed may be 90 rpm.

In this case, the plurality of basalt fibers (BF) provided from the plurality of bobbins (BN) are first aligned through the first spreading module 322 and then spread through the second spreading module 324. Can be sorted secondary. That is, the plurality of basalt fibers (BF) are primarily aligned through a relatively slow motor rotation speed (e.g., 90 rpm) and a friction rotation speed (e.g., 70 rpm) and then driven by a relatively fast motor. Alignment may be secondary through rotational speed (e.g., 110 rpm) and frictional rotational speed (e.g., 90 rpm).

Accordingly, alignment of the plurality of basalt fibers (BF) may be improved. Specifically, when only primary alignment is performed through the first spreading module 322, the plurality of basalt fibers BF arranged side by side may be arranged irregularly, thereby reducing alignment. However, as described above, when performing primary alignment through the first spreading module 322 and then performing secondary alignment through the second spreading module 324, a plurality of aligned side by side The basalt fibers (BF) are regularly arranged in parallel, so alignment can be improved.

The plurality of basalt fibers (BF) aligned and spread through the first and second spreading modules 322 and 324 may be provided into the interior of the impregnation tank 330 containing the thermoplastic resin. Accordingly, the basalt fibers (BF) provided inside the impregnation tank 330 may be impregnated with the thermoplastic resin. According to one embodiment, the thermoplastic resin is polypropylene (PP, polypropylene), polyethylene (PE, polyethylene), polycarbonate (PC, polycarbonate), polyamide (PA, polyamide), and polyphenylene sulfide (PPS, polyphenylenesulfide). , polyethyleethyleketon (PEEK), or a mixture thereof, and a liquid thermoplastic resin (for example, an acrylic resin, etc.) may be used.

According to one embodiment, the impregnation tank 330 may control the temperature of the thermoplastic resin so that the thermoplastic resin does not enter a gel state. In contrast, when the thermoplastic resin is in a gel state, a problem may arise in which it becomes difficult to maintain the shape of the base rod, which will be described later. Additionally, an impregnation tank designed to use liquid thermoplastic resin can be used.

According to one embodiment, before the plurality of basalt fibers (BF) are impregnated into the thermoplastic resin, the plurality of basalt fibers (BF) may be dried at a temperature of 100° C. for 24 hours. Accordingly, the coating efficiency of the thermoplastic resin can be improved. On the other hand, if the plurality of basalt fibers (BF) are not dried before being impregnated in the thermoplastic resin, a problem may occur in which the coating efficiency of the thermoplastic resin is reduced due to moisture on the surface of the basalt fibers (BF). there is.

The plurality of basalt fibers (BF) impregnated with the thermoplastic resin may be provided from the impregnation tank 330 to the collector 340. The collector 340 may receive a plurality of basalt fibers (BF) impregnated in the thermoplastic resin from the impregnation tank 330 and collect them to a certain size.

Referring to FIG. 2, a plurality of basalt fibers (BF) collected through the collector 340 may be provided to the cooling module 350. The cooling module 350 can cool the plurality of basalt fibers (BF) and then provide them to the prepreg tape manufacturing module 360, which will be described later.

According to one embodiment, the cooling module 350 provides a cooling fluid toward the plurality of basalt fibers (BF) while the plurality of basalt fibers (BF) are wound on the surface, thereby forming a plurality of the basalt fibers (BF). BF) can be cooled. For example, the cooling fluid provided to the surface of the plurality of basalt fibers (BF) may be provided at an air pressure of 2 to 3 bar.

The prepreg tape manufacturing module 360 can manufacture a prepreg tape (PT) in which a plurality of the basalt fibers (BF) impregnated with the thermoplastic resin are bundled so that they are laterally aligned. The prepreg tape (PT) may be provided from the prepreg tape manufacturing module 360 to the preforming module 370, which will be described later.

Referring to FIG. 3, the preforming module 370 can receive a plurality of prepreg tapes (PT) from the prepreg tape manufacturing module 360 and bundle the plurality of prepreg tapes (PT). . Accordingly, a base rod (BR) in which a plurality of the prepreg tapes (PT) are arranged in the longitudinal direction can be manufactured. The base load (BR) may be provided from the preforming module 370 to the riba manufacturing module 380, which will be described later.

Figures 5 and 6 are diagrams for explaining the first press wheel of the rib manufacturing apparatus according to the first embodiment of the present invention, and Figures 7 and 8 are diagrams of the first press wheel of the rib manufacturing apparatus according to the first embodiment of the present invention 1 is a drawing for explaining the manufacturing of a base rod through a press wheel and a second press wheel, and FIGS. 9 and 10 illustrate the formation of a rib pattern through a third press wheel of the rib manufacturing device according to the first embodiment of the present invention. 11 and 12 are drawings for explaining the formation of a rib pattern through a third press wheel in the rib manufacturing apparatus according to a modified example of the present invention.

Referring to FIGS. 5 to 10 , the riba manufacturing module 380 may include a first press wheel 381, a second press wheel 382, and a third press wheel 383. The base load BR provided from the twister 370 may sequentially pass through the first to third press wheels 381, 382, and 383.

The first press wheel 381 and the second press wheel 382 may reduce the diameter by compressing the base rod BR. More specifically, the first press wheel 381 includes an upper first press wheel 381a and a lower first press wheel 381a disposed opposite to the upper first press wheel 381a, as shown in FIGS. 5 and 6. 1 May include a press wheel (381b). The upper first press wheel 381a and the lower first press wheel 381b may each rotate clockwise or counterclockwise about the first direction. For example, the first direction may be a direction perpendicular to the direction in which the upper first press wheel 381a and the lower first press wheel 381b face each other.

An empty space may be formed between the upper first press wheel 381a and the lower first press wheel 381b. The base rod BR provided from the twister 370 may be provided to the empty space between the upper first press wheel 381a and the lower first press wheel 381b. With the base rod BR provided in the empty space, the upper first press wheel 381a and the lower first press wheel 381b may be rotated. Alternatively, the base rod BR may be provided in the empty space while the upper first press wheel 381a and the lower first press wheel 381b are rotated. Accordingly, the base rod BR may be compressed by rotation of the upper first press wheel 381a and the lower first press wheel 381b, thereby reducing the diameter of the base rod BR.

The second press wheel 382 may include an upper second press wheel 382a and a lower second press wheel 382b disposed opposite to the upper second press wheel 382a. An empty space may also be formed between the upper second press wheel 382a and the lower second press wheel 382b, and the base rod BR may be provided in the empty space of the second press wheel 382. You can. Pressure may be applied to the base rod BR provided in the empty space by the upper second press wheel 382a and the lower second press wheel 382b. Accordingly, the base rod (BR) may be compressed, thereby reducing the diameter of the base rod (BR).

According to one embodiment, as shown in FIG. 8, the sizes of empty spaces of the first and second press wheels 381 and 382 may be different. That is, the distance (d ₁ ) between the upper first press wheel 381a and the lower first press wheel 381b of the first press wheel 381, the upper second press wheel of the second press wheel 382 The distance (d ₂ ) between (382a) and the lower second press wheel (382b) may be different. Specifically, the distance (d ₂ ) between the upper second press wheel 382a and the lower second press wheel 382b of the second press wheel 382 is the upper first press wheel 381 It may be shorter than the distance d ₁ between the wheel 381a and the lower first press wheel 381b.

Accordingly, the first base rod (BR ₁ ) before being pressed through the first press wheel 381, the second base rod (BR 2 ) pressed through the first press wheel 381, and the second base rod (BR ₂ ) before being pressed through the first press wheel 381. The diameters of the third base rods BR ₃ pressed through the press wheel 382 may be different. Specifically, the diameter (d ₃ ) of the third base rod (BR ₃ ) may be smaller than the diameter (d ₂ ) of the second base rod (BR ₂ ). Additionally, the diameter (d ₂ ) of the second base rod (BR ₂ ) may be smaller than the diameter (d ₁ ) of the first base rod (BR ₁ ). That is, the diameter of the base rod BR provided from the twister 370 may gradually decrease through the first and second press wheels 381 and 382.

Because of this, the productivity of the base load (BR) can be improved. Specifically, unlike what was described above, when manufacturing a base rod through a single press wheel, problems may arise in which process time and cost are increased to reduce the thickness of the base rod. However, as described above, when the thickness of the base rod (BR) is gradually reduced through the plurality of press wheels (381, 382), the thickness of the base rod (BR) is easily reduced, so that the base Rod (BR) productivity can be improved.

Referring to FIGS. 9 and 10 , the third base rod BR ₃ manufactured through the second press wheel 382 may be provided as the third press wheel 383. The third press wheel 383 may apply pressure to the third base rod BR ₃ to form a rib pattern RP on the surface of the third base rod BR ₃ . Accordingly, a rib (RB) having a rib pattern (RP) formed on the surface of the third base rod (BR ₃ ) can be manufactured.

According to one embodiment, the third press wheel 383 may include an upper third press wheel 383a and a lower third press wheel 383b disposed opposite to the upper third press wheel 383a. there is. The upper third press wheel 383a and the lower third press wheel 383b may be rotated clockwise or counterclockwise about a first direction (eg, X-axis direction).

The upper third press wheel 383a may include upper master patterns 383ap ₁ and 383ap ₂ , and the lower third press wheel 383b may include lower master patterns 383bp ₁ and 383bp ₂ . The upper master patterns 383ap ₁ and 383ap ₂ and the lower master patterns 383bp ₁ and 383bp ₂ may include concave portions and convex portions, respectively.

While the upper third press wheel 383a and the lower third press wheel 383b are rotated, the third base rod is between the upper third press wheel 383a and the lower third press wheel 383b. (BR ₃ ) may be provided. Accordingly, pressure may be applied to the third base rod BR ₃ through the upper third press wheel 383a and the lower third press wheel 383b.

According to one embodiment, before pressure is applied to the third base rod (BR ₃ ), or while pressure is applied to the third base rod (BR ₃ ), the riba manufacturing module 380 3 The base rod (BR ₃ ) can be heat treated. When the third base rod BR ₃ is heat treated, the surface of the third base rod BR ₃ may be softened by the thermoplastic resin.

When pressure is applied to the third base rod (BR ₃ ) while the third base rod (BR ₃ ) is heat treated, the rib pattern (RP) is formed on the surface of the third base rod (BR ₃ ). It can be.

Specifically, when pressure is applied to the third base rod (BR ₃ ) through the upper third press wheel (383a) and the lower third press wheel (383b), the third base rod (BR ₃ ) The rib pattern RP may be formed on the surface.

According to one embodiment, the rib pattern RP may have an inverse image of the upper master patterns 383ap ₁ and 383ap ₂ and the lower master patterns 383bp ₁ and 383bp ₂ . More specifically, the rib pattern (RP) also has concave portions and convex portions like the upper master patterns (383ap ₁ , 383ap ₂ ) and the lower master patterns (383bp ₁ , 383bp ₂ ), and the rib pattern (RP) The convex portions correspond to the concave portions of the upper master patterns (383ap ₁ , 383ap ₂ ) and the lower master patterns (383bp ₁ , 383bp ₂ ), and the concave portions of the rib pattern (RP) correspond to the upper master patterns (383ap ₁ , 383ap). ₂ ) and may correspond to the convex portions of the lower master patterns (383bp ₁ , 383bp ₂ ).

That is, after the third base rod (BR ₃ ) is heat treated to form a smooth surface, pressure is applied through a press wheel having a master pattern, thereby forming the master pattern on the surface of the third base rod (BR ₃ ). The rib pattern RP having a reverse phase may be formed.

According to one modification, as shown in FIG. 11 , the upper master patterns 383ap ₁ and 383ap ₂ and the lower master patterns 383bp ₁ and 383bp ₂ may have different shapes. Accordingly, rib patterns RP of different shapes may be formed on the surface of the third base rod BR ₃ . Specifically, as shown in FIG. 12, in the first region ( _{BR a} ) of the third base rod (BR ₃ ), _a first rib pattern ( RP ₁ ) is formed, and in the second region (BR _b ) of the second base rod (BR ₂ ), a second rib pattern (RP ₂ ) having an inverse phase of the lower master pattern (383bp ₁ , 383bp ₂ ) is formed.

The durability of concrete structures constructed with Riva (RB) can be improved. In contrast, in the case of the conventional technology of forming a rib pattern by providing separate fibers, etc. on the surface of the base rod, the base rod and the rib pattern do not form a single body, so the rib pattern is separated from the base rod. This separation problem may occur. As a result, the adhesion with concrete is reduced, which may cause a problem in which the durability of the concrete structure in which the tubular riba (RB) is installed is reduced.

In addition, in the case of conventional riba containing thermosetting resin, it is manufactured in advance in a specific shape and then supplied to the field, so there is a problem of low convenience of use and application efficiency in the field.
