Abstract
The utility model discloses a steel accessory for built-in I-shaped roof hanging keels. The steel accessory which is used for providing indoor ceiling boards of buildings is suitable for matching with hanging ceiling boards with various materials to realize the built-in installation of hidden keels. The upper and lower wing boards of the I-shaped keels are double-layer boards with flanges held together tightly, and the ventral plate is a single-layer board. A T-shaped connector has a slot-shaped upper wing board, and plug-in sheets used for connecting the two I-shaped keels are arranged on the ventral plate of the T-shaped connector. A rotating elevator is a plate-shaped member whose middle part is provided with two convex bent boards for connecting the upper wing boards of the I-shaped keels, and the both sides of the rotating elevator is provided with a structure sheet connected with a bearing keel is used for lifting the I-shaped keels on the bearing keel.
Description
The utility model is a kind of steel channel matching component that supplies building indoor set ceiling to use.Be suitable for and the supporting use of the ceiling board of various materials, realize the dark formula installation that keel do not expose.The utility model comprises I type keel, T type connector and rotates elevator totally three kinds of members, do not comprise the load-bearing keel supporting with it and other auxiliaries.
The like product that at present external well-known manufacturer is produced, the primary structure feature of its I type (also claiming the H type) keel is that upper flange is made lamina, web and lower wing plate are made doubling plate, as shown in Figure 1.The connector that is used for spreading I type keel is formed with two L shaped plates, as shown in Figure 2.Be used to lift the elevator of I type keel, common have steel wire elevator shown in Figure 3 and a board-like elevator shown in Figure 4.The design of these members exists room for improvement.The supporting capacity of above-mentioned I type keel and the actual external force of bearing are inconsistent.The connector of above-mentioned pair of L plate can replace with the connector of a plate.Above-mentioned steel wire elevator can produce elastic deformation and influence the planarization of ceiling furred ceiling when stand under load is big.Above-mentioned board-like elevator is difficult to dismounting behind I type keel installation in position, constructional difficulties when needing temporarily to increase and decrease hanging piece.
The purpose of this utility model is to provide a kind of channel accessory of new construction, makes the mechanical property of its structure more reasonable, can increase and decrease hanging piece easily behind I type keel installation in position, and can save material, reduces technology difficulty, reduces production costs.
Now the concrete structure and the feature of three kinds of members that in conjunction with the accompanying drawings the utility model comprised describe.
Fig. 5 is the utility model unit construction scheme of installation.(1) is I type keel among the figure, and (2) are T type connectors, and (3) are to rotate elevator, and (4) are ceiling boards, and (5) are the load-bearing keel.The lower wing plate of I type keel (1) is used for setting-in ceiling board (4), and T type connector (2) is used for two I type keel (1) spreading for whole.Rotating elevator (3) is used for I type keel (1) are lifted on load-bearing keel (5).
Fig. 6 is that the axle of I type keel is surveyed view.
Fig. 7 is that the axle of T type connector is surveyed view.Fig. 8 is that the axle that rotates elevator is surveyed view.
The structure of I type keel is seen Fig. 6, and its cross section is the I font.With the moulding of band steel roll extrusion flanging.Its feature one is that upper flange also tightly becomes double panel structure with lower wing plate with the plate bending.Web is the lamina structure.The flexural strength of known steel is less than tensile strength.From the stressed consideration of cross section, upper flange and lower wing plate mainly bear moment of flexure, make doubling plate and can improve bending resistance.Web bears pulling force, makes lamina and can reduce materials.Vertically bear moment of flexure from whole keel and consider that upper and lower wing plate is made the module of anti-bending section that doubling plate has increased member, thereby has improved the supporting capacity of member.Feature two is to make rectangular opening at I type keel two ends, uses when connecting for T type connector.Feature three is longitudinally to make half garden shape convex tendon at I type keel web middle part, is used for improving the longitudinal rigidity of whole keel, and play the guiding role in pressing process.
The structure of T type connector is seen Fig. 7.Its cross section is the T font, with the moulding of band steel roll extrusion flanging, is made of single-piece.Its feature one is that upper flange is the double panel structure that flanging becomes dead slot, and the inner chamber of dead slot can contain the upper flange of above-mentioned I type keel.During connection two I type keel are inserted the inner chamber of described groove respectively, realize located lateral by it.Feature two is that web is a lamina, and its height is consistent with above-mentioned I type keel web height.Feature three is to make insert-connecting plate two places on web, and this insert-connecting plate inserts respectively in the rectangular opening of two connected I type keel ends during connection, and bending and tight, plays longitudinal register and tightens up effect.
Rotate the structure of elevator and see Fig. 8.Make through the punching press flanging with steel sheet.Its feature one is to make the bent plate of two place's projectioies through pressing and bending at the middle part of plate, this bent plate through twice 90 ° be bent into
Shape, two bent plate spaces are relative, form a space, and its size can contain the upper flange of above-mentioned I type keel.This upper flange inserts this space orientation during installation.Feature two is that above-mentioned two bent plate inner side edges become constant slope with center line, and this two hypotenuses spacing (seeing Fig. 8 size A) is consistent with above-mentioned I type keel upper flange width, and this upper flange rotates through this hypotenuse spacing and inserts during installation.Also can rotate dismounting after the installation, be used for solving construction and run into the problem that light fixture, air port etc. need interim increase and decrease hanging piece of installing through this hypotenuse spacing.Feature three is in the both sides of rotating elevator the structure sheet that is mutually 90 ° to be arranged, during installation with this two structures bending tablet fastening on the load-bearing keel.Feature four is respectively to suppress a convex tendon on the flanging of above-mentioned two protruding bent plates, is used for improving the rigidity of flanging.
The advantages such as three members that the utility model comprises are compared with aforementioned same kind of products at abroad, have reliable in structure, and are easy for installation, and structural mechanical property is reasonable have the function that can increase and decrease easily hanging piece behind I type keel hoisted in position. Wherein I type keel can be economized on material about 20% than same kind of products at abroad.
