Description

a curtain wall

technical field

The invention relates to the technical field of curtain wall decoration, in particular to a novel curtain wall system.

Background technique

There are many types of nodes in the original curtain wall structure, and the profiles of almost every project are different. It is very wasteful to constantly update the molds for aluminum profile processing. The connection nodes of the curtain wall are also very different, and there is no unified general rule. The specifications and types of accessories are even more chaotic and cannot be universally configured. The specific problems are mainly manifested in the following aspects:

1. The sub-frame of the glass is generally completed by secondary bonding on the outside of the insulating glass, which increases the cost and is difficult to guarantee the quality. At the same time, due to the certain width of the auxiliary frame, the center of gravity of the curtain wall glass has a large eccentricity relative to the column and beam, and the stress situation is not reasonable.

2. In the connection between the column and the beam of the curtain wall, the traditional connection method is to consider two parts of the closed cavity and the open cavity in the design of the beam. In the open cavity, use the connecting angle code to connect the column with the fastener and then It is closed with a cover plate to achieve the purpose of smooth and beautiful appearance of the beam. However, since the operation of the connecting angle brackets for columns and beams is completed in the opening of the beam, the operating space is small, the number and spacing of the fasteners that can be screwed in are limited, and the fasteners cannot be fully distributed. The four corners of the crossbeam make the effect of connection and fixation not ideal. For example, in the Chinese patent ZL201010520015, a wedge-type connection structure is proposed, including a column, a beam, a core sleeve, and a connecting corner. The core is set in the beam, and the connecting corner is fixed on the column. Fasteners such as screws are tightly fixed. Although in this structure the connecting angle bracket is directly fixed to the beam, and is connected through a core sleeve, this connection method is still completed in the opening of the beam, the operating space is limited, and the fixed installation method cannot be adjusted flexibly. Affects the stress stability of the connection between the beam and the column.

3. In the design of the existing curtain wall connection nodes, the hooks bearing the horizontal load of the upper curtain wall, the supporting plate bearing the self-weight load of the curtain wall, and the pressure plate bearing the horizontal load of the lower curtain wall are all separated independently. Not only are there many types, but also they cannot work together, and installation is also inconvenient.

Detailed ways

The preferred embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings.

The present invention is a curtain wall, and mainly involves large parts including hollow glass 1 , connection node 1 , connection node 2 3 , horizontal decorative frame 4 , vertical decorative frame 5 , column 21 , and beam 22 .

First, the columns 21 and beams 22 of the curtain wall are assembled into the structural main body of the curtain wall by using the connection node 1 2, and then the insulating glass 1 and the connection node 2 3 are assembled to form a new type of hidden frame curtain wall system. According to needs, adding the horizontal decorative frame 4 becomes a horizontally visible and vertically hidden curtain wall system, as shown in Figure 1 and Figure 3; adding a vertical decorative frame 5 becomes a vertically bright, horizontally hidden curtain wall system, as shown in Figure 2 and Figure 19. Adding the horizontal decorative frame 4 and the vertical decorative frame 5 at the same time becomes a curtain wall system with full bright frames.

The following is a detailed description of each major component:

Insulating glass 1, see Figure 21 to Figure 24, mainly includes two pieces of glass 11, a hollow layer 12 formed between the glass, a spacer frame 13 filled with desiccant, inner sealant 14, metal profiles 15, outer sealing structure glue16.

A spacer frame 13 equipped with a desiccant is arranged around the two pieces of glass 11, and an inner sealant 14 is applied on both sides of the spacer frame 13 for sealing and fixing. The airtight space formed by bonding the spacer frame 13 and the two pieces of glass 11 is the hollow layer 12 . After the inner layer sealant 14 is solidified and fixed, a groove 17 is formed between the outer side of the spacer frame 13 and the two pieces of glass 11, and the metal profile 15 is placed in the groove 17, and then the groove 17 and the metal profile 15 are formed. Put the outer layer sealing structure glue 16 in the gap.

Here, the metal profile 15 is in a U-shaped structure, and its U-shaped inner end is designed as a circular part 151, which increases the contact area with the outer sealing structural adhesive 16, so that the outer sealing structural adhesive 16 will not be damaged by the metal profile 15. There are sharp corners and local stress fatigue damage occurs. The circular portion 151 can also increase the elasticity of the U-shaped opening of the metal profile 15 , so that it can synchronously and synergistically cooperate with the outer sealing structure glue 16 to bear the external force acting on the glass 11 together. In order to further increase the contact area between the metal profile 15 and the outer sealant 16, the outside of the circular bottom of the metal profile can also be designed as a zigzag structure, as shown in Figure 21 and Figure 22. At the same time, for the convenience of installation, the U-shaped opening 152 of the metal profile 15 expands outwards and is in the shape of a trumpet. It can be partially expanded, as shown in Figure 21 and Figure 23 , or the entire opening 152 can be expanded outward, as shown in Figure 22 and Figure 24 .

Connection node one 2 is mainly the node that connects the column 21 and the beam 22, referring to Fig. 5 to Fig. 13 , it mainly includes a toothed pin 23, a fastening screw 24, a spur gear 25, and a sleeve core 26.

In the present invention, the crossbeam 22 can be designed as a complete closed cavity to improve the compressive bending strength and torsional strength of the crossbeam 22 . In the cavity of the crossbeam 22, a space that can be inserted into the sleeve core 26 is designed, and the sleeve core 26 can be cut or customized according to the cross-sectional size of the crossbeam 22.

A circular cavity is provided inside the sleeve core 26 as a gear hole 262 for installing the spur gear 25 , and one end of the spur gear is provided with a slot 251 . In the direction perpendicular to the gear hole 262 of the sleeve core 26, a pin hole 261 is drilled on the sleeve core according to the cross-sectional size of the crossbeam 22. The number of the pinholes 261 is generally at least two, so that the crossbeam 22 is guaranteed to be stably fixed on the sleeve core. Column 21. Two toothed pins 23 are placed in the two pin holes 261 respectively. The intersection of the pin hole 261 and the gear hole 262 communicates. At the same time, the tooth pitch of the toothed pin 23 and the tooth pitch of the spur gear 25 are matched and meshed with each other. After the two are installed separately like this, ensure that the toothed pin 23 and the spur gear 25 are meshed with each other.

On the outside of the beam 22 facing outdoors, a circular hole 221 is opened corresponding to the center of the spur gear 25 , and the circular hole 221 is smaller than the inscribed circle of the spur gear 25 . Two circular holes 211 are provided at positions corresponding to the toothed pins 23 on the column. During installation, use a flat-blade screwdriver to pass through the round hole 221 of the beam and insert it into the slot 251 at one end of the spur gear 25 to rotate the spur gear 25, and the spur gear 25 drives two gears with teeth. The pin bolt 23 moves horizontally until the toothed pin bolt 23 is inserted into the two circular holes 211 on the column and fully engaged. the

In order to prevent the spur gear 25 from loosening, the fastening screw 24 is inserted into the slot 251 at one end of the spur gear 25 through the round hole 221 of the cross beam 22, and continues to be screwed in until the fastening screw 24 is screwed into the cross beam 22. The side wall is fixed, and at the same time, it is clamped in the slot 251 of the spur gear, so that the spur gear 25 can no longer rotate, effectively preventing the spur gear 25 from turning and withdrawing, so that the toothed pin 23 is not fixed. Move, reach the purpose that is effectively connected with column 21, after connection finishes, 221 holes are sealed with sealant. If the position of crossbeam 22 needs to be changed or replaced, as long as fastening screw 24 is unscrewed, reverse direction rotation of spur gear 25 drives toothed pin bolt 23 to withdraw from two circular holes 211 on the column. the

In addition, what needs to be explained here is that, according to the internal structure of the actual beam 22, the fixing method of the sleeve core 26 can also be determined according to the actual situation. As shown in FIG. . As shown in Fig. 14 again, when the cross-section of the cross-beam 22 changes into a cross-section 28, there is no rib to rely on, so the set screw 27 can be used to fix the core 26 and the cross-beam 28.

Of course, the structure of the pin hole 261 inside the sleeve core 26 can also be properly adjusted. In Fig. 5 to Fig. 14, the pin hole 261 is fully enclosed inside the sleeve core 26, and as shown in Fig. After the bolt 23 is installed in the pin hole 261 , a part may be exposed on the surface of the sleeve core 26 . And the sleeve core 26 can also be designed to be filled in the inner cavity of the entire crossbeam 22 depending on the situation, as shown in Fig. 17 and Fig. 18, and can also be arranged only in a partial space of the crossbeam 22 as shown above. the

The crotch at the rear end of the fixing part 34 is used to Compress the lower insulating glass 1 to bear the horizontal load of the lower insulating glass.

The insert 32 can be inserted into the middle of the groove 31 on the beam 22 , and the upper and lower sides are against the L-shaped hook 35 and the fixing piece 34 . A side of the insert 32 corresponding to the L-shaped hook 35 is provided with a horizontally protruding supporting plate 36 for bearing the weight of the upper insulating glass 1 . The rear barb 321 of the inserter 32 can hook the L-shaped hook 35 and the fixing member 34 so that the three are engaged together, and finally the fastener 33 passes through the inserter 32 to connect it with the beam 22 . In this way, the L-shaped hook 35 on the beam 22, the plug-in 32 and the fixing piece 34 work together to strengthen the strength of the supporting plate 36 on the plug-in 32, improve the overall synergistic effect, and increase the bending resistance and torsional strength of the entire component. .

Then the inserter 32 is clamped in the middle of the fixture 34, inserted into the middle of the groove 31, and the outer end of the inserter 32 hooks the fixture 34 in the same way, and then the fastener 33 passes through the inserter 32 and is connected to the column 21 as a whole.

In this structure, the groove 31 is arranged vertically. In order to prevent the above-mentioned accessories from sliding down along the groove 31 during installation, a corner bracket 37 is also provided. The corner bracket 37 is fixed on the column 21 through a corner bracket fastener 38. The horizontal portion of angle sign indicating number 37 is just used as the horizontal base of all the other parts. After first connecting the angle code 37 with the column 21 through the angle code fastener 38 during installation, other rear assembly parts can be prevented from sliding down.

The horizontal decorative frame 4 and the vertical decorative frame 5 can be externally decorated according to different requirements of the curtain wall structure. The horizontal decorative frame 4 includes a heat insulating pad 41 , a sealing rubber strip 42 , a pressing plate 43 , a fastener 44 , and a decorative line 45 . The vertical decorative frame 5 also includes a heat insulating pad 51 , a sealing rubber strip 52 , a pressing plate 53 , a fastener 54 , and a decorative line 55 . Both structures and principles are the same, and the present invention will be described on one of them.
