Description

Technical Field

[0001] The utility model relates to the technical field of floor bearing plates, and particularly relates to a new type of steel bar truss floor bearing plate. Background Art

[0002] With the continuous development of social economy and the acceleration of the urbanization process, the prefabricated buildings in China have witnessed an explosive development. The steel bar truss floor bearing plate is formed by welding steel bar trusses on a thin galvanized steel plate, forming a stable spatial triangular truss, which also serves as the bottom formwork and support of the cast-in-place floor slab and does not need to be removed after construction. When connecting two adjacent steel bar truss floor bearing plates, the traditional construction has high efficiency but only uses simple snap connection, with unstable fixation. During construction, the galvanized steel plates are likely to separate, thus affecting the pouring of cement. Moreover, the contact range at the interface between the traditional steel bar truss and the galvanized steel plate is small, and the welding is not firm, making it inconvenient to use. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a new type of steel bar truss floor bearing plate in view of the above-mentioned existing technical deficiencies. With this structure, the connection between adjacent steel bar truss floor bearing plates is more stable, and the fixation between the steel bar truss and the galvanized steel plate is more stable, thus ensuring the firmness and reliability of this structure.

[0004] The technical solution adopted by the utility model is as follows: A new type of steel bar truss floor bearing plate is provided, which includes a galvanized steel plate and a steel bar truss cooperating with it. It also includes fixing brackets arranged at both ends of the steel bar truss. The steel bar truss is connected to the galvanized steel plate through the fixing brackets. It is characterized in that: First connection blocks and second connection blocks are respectively fixedly connected to both ends of the galvanized steel plate; a card slot is opened on the first connection block, and a card plate corresponding to the card slot is opened on the second connection block; the lower part of the card slot is larger than the upper part of the card slot, and a deformation block corresponding to the card plate is arranged in the card slot; the height of the card plate is higher than the depth of the card slot; after the card plate contacts the deformation block, it deforms so that the card plate fits and is snap-connected with the lower part of the card slot; a strengthening connection frame is fixedly connected to the lower end of the fixing bracket.

[0005] Further optimizing this technical solution, the card slot of a new type of steel bar truss floor bearing plate is in an inverted "T" shape; the card plate is in a "U" shape; the deformation block is arranged at the bottom end of the card slot, and the deformation block is a protruding triangle.

[0006] Further optimizing this technical solution, the deformation block of a new type of steel bar truss floor bearing plate corresponds and cooperates with the middle part of the lower end of the card plate.

[0007] Further optimizing this technical solution, the upper end surface of the first connection block of a new type of steel bar truss floor bearing plate is higher than the upper end surface of the galvanized steel plate; a buckling groove for buckling and cooperating with the first connection block is opened on the second connection block; the card plate is located on the buckling groove.

[0008] To further optimize this technical solution, a plurality of welding grooves corresponding to the steel bar truss are formed on a fixing bracket of a new type of steel bar truss floor slab.

[0009] To further optimize this technical solution, a reinforcing connecting frame of a new type of steel bar truss floor slab is cross-shaped.

[0010] To further optimize this technical solution, a reinforcing connecting frame of a new type of steel bar truss floor slab is "T"-shaped.

[0011] To further optimize this technical solution, a reinforcing connecting frame of a new type of steel bar truss floor slab is spiral-shaped.

[0012] Compared with the traditional steel bar truss floor slab, the beneficial effects of the present utility model are as follows:

[0013] 1. The cooperation of the first connecting block, the second connecting block, the galvanized steel plate, the buckling groove, the clamping plate, the deformation block and the clamping groove facilitates the connection and fixation of adjacent galvanized steel plates, and the connection is more stable, preventing the adjacent galvanized steel plates from separating during construction and affecting the pouring of cement.

[0014] 2. The setting of the fixing bracket and the welding groove is more convenient for welding and fixing; the reinforcing connecting frame is cross-shaped or spiral-shaped, and the contact area during welding is larger and the welding is more stable; the reinforcing connecting frame is "T"-shaped, which increases the welding contact area and prevents the fixing bracket from protruding to the outside of the galvanized steel plate; the shape of the reinforcing connecting frame can be used according to different usage situations.

[0024] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] As Figure 1-8 shown, a new type of steel bar truss floor slab includes a galvanized steel plate 1 and a reinforced steel truss 2 cooperating therewith, and further includes fixed supports 3 provided at both ends of the reinforced steel truss 2. The reinforced steel truss 2 is connected to the galvanized steel plate 1 through the fixed supports 3. It is characterized in that: first connecting blocks 4 and second connecting blocks 5 are respectively fixedly connected to both ends of the galvanized steel plate 1; a card slot 6 is formed on the first connecting block 4, and a clamping plate 7 corresponding to the card slot 6 is formed on the second connecting block 5; the lower part of the card slot 6 is larger than the upper part of the card slot 6, and a deformation block 8 corresponding to the clamping plate 7 is arranged in the card slot 6; the height of the clamping plate 7 is higher than the depth of the card slot 6; after the clamping plate 7 contacts the deformation block 8, it deforms so that the clamping plate 7 fits and is clamped with the lower part of the card slot 6; a reinforcing connecting frame 9 is fixedly connected to the lower end of the fixed support 3; the card slot 6 is in an inverted "T" shape; the clamping plate 7 is in a "U" shape; the deformation block 8 is arranged at the bottom end of the card slot 6, and the deformation block 8 is a protruding triangle; the deformation block 8 corresponds to and cooperates with the middle part of the lower end of the clamping plate 7; the upper end surface of the first connecting block 4 is higher than the upper end surface of the galvanized steel plate 1; a buckling groove 10 for buckling and cooperating with the first connecting block 4 is formed on the second connecting block 5; the clamping plate 7 is located on the buckling groove 10; a plurality of welding grooves 11 corresponding to the reinforced steel truss 2 are formed on the fixed support 3; the reinforcing connecting frame 9 is in a cross shape; the reinforcing connecting frame 9 is in a "T" shape; the reinforcing connecting frame 9 is in a spiral shape.

[0026] The lower part of the card slot 6 is larger than the lower part of the card slot 6, and the specific structure is as Figure 3 shown; the specific structures of the second connecting block 5 and the clamping plate 7 are as Figure 7 shown;

[0027] During use, adjacent galvanized steel plates 1 are placed together through the first connecting block 4 and the second connecting block 5, and the buckling groove 10 at the second connecting block 5 is buckled onto the first connecting block 4, as Figure 7As shown, the clamping plate 7 is inserted into the clamping groove 6. Then, the second connecting block 5 is pressed downward. The second connecting block 5 drives the clamping plate 7 in the clamping groove 10 to move downward. After the clamping plate 7 contacts the deformation block 8, the lower end of the clamping plate 7 deforms. After the lower end of the clamping plate 7 deforms, it fits with the lower part of the clamping groove 6. Thus, the clamping plate 7 is clamped into the clamping groove 6, and the connection between adjacent galvanized steel plates 1 is more stable and convenient. When cement is poured onto the galvanized steel plate 1, the gravity of the cement is greater, which provides a downward pressure on the second connecting block 5 again, making the other parts of the second connecting block 5 that are not pressed down fit more closely with the first connecting block 4, facilitating the connection and fixation of adjacent galvanized steel plates 1 and making the connection more stable, preventing the adjacent galvanized steel plates 1 from separating during construction and affecting the pouring of cement.

[0028] The welding groove 11 provided on the fixing bracket 3 enables the fixing bracket 3 to have a larger contact area with the steel bar truss 2, making it more convenient for welding and fixing. The strengthening connecting frame 9 is in a cross shape or a spiral shape, so that the strengthening connecting frame 9 has a larger contact area with the galvanized steel plate 1, thus having a larger contact area during welding and making the welding more stable. The strengthening connecting frame 9 is in a "T" shape. When the fixing bracket 3 is located outside the galvanized steel plate 1, while increasing the welding contact area, the fixing bracket 3 will not protrude outside the galvanized steel plate 1. The shape of the strengthening connecting frame 9 can be used according to different usage situations.
