Description

Technical Field

[0001] This utility model relates to the field of composite plate connection technology, specifically a prefabricated steel structure composite plate connection structure. Background Technology

[0002] Composite slabs are a type of building formwork that combines precast and cast-in-place concrete. The slab itself serves as the formwork for pouring concrete, and the strength and rigidity of the formwork are provided by steel trusses welded together with the keel. Composite slabs are characterized by fire resistance, moisture resistance, corrosion resistance, and good stability.

[0003] In the existing technology, composite slabs, as a type of building formwork, mainly replace traditional iron, steel, aluminum, and wooden formwork. They play an important role in the field of precast formwork such as basement post-pouring strips, foundations, retaining walls, and cast-in-place roofs. However, when they are connected to the wall panels, gaps are prone to appear at the joints, which can lead to instability and result in unstable installation of the composite slabs.

[0007] According to the prefabricated steel structure composite plate connection structure, a left stabilizing plate is fixed to the top and bottom of the left side of the first connecting plate, and a right stabilizing plate is fixed to the top and bottom of the right side of the second connecting plate. The left and right stabilizing plates on the top side are fixedly connected to the lower clamping block, and the left and right stabilizing plates on the bottom side are fixedly connected to the upper clamping block.

[0008] According to the prefabricated steel structure composite plate connection structure, the strength of the multiple upper and lower reinforcing ribs is good.

[0009] According to the prefabricated steel structure composite plate connection structure, the front and rear sides of the first connecting plate and the second connecting plate are both fixed with moisture-proof membranes.

[0010] According to the prefabricated steel structure composite plate connection structure, the left and right borrow plates are both chamfered on their opposite sides.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a prefabricated steel structure composite slab connection structure, including an inner wall panel 1, an outer wall panel 2 mirrored along the center of the inner wall panel 1, a first composite slab 3 and a second composite slab 4 disposed between the inner wall panel 1 and the outer wall panel 2, a first connecting plate 5 and a second connecting plate 6 disposed between the inner wall panel 1 and the outer wall panel 2, the first connecting plate 5 and the second connecting plate 6 being mirrored, a left shim 7 fixed to the right side of the first composite slab 3, the first connecting plate 5 being inserted into the inner side of the left shim 7, a right shim 8 fixed to the left side of the second composite slab 4, the second connecting plate 6 being inserted into the inner side of the right shim 8, a left reinforcing bolt 9 threadedly connecting the first connecting plate 5 and the left shim 7, and a right reinforcing bolt 10 threadedly connecting the second connecting plate 6 and the right shim 8. In the prior art, composite slabs, as a type of building formwork, mainly replace traditional iron and steel slabs. Aluminum and wooden formwork play an important role in precast formwork applications such as basement post-pouring strips, foundations, retaining walls, and cast-in-place roofs. However, when connecting them to wall panels, gaps can easily appear at the joints, leading to instability and unstable installation of the composite slabs. To address this issue, the first composite slab 3 and the second composite slab 4 can be placed between the inner wall panel 1 and the outer wall panel 2, ensuring they fit tightly together. At this point, the right side of the first composite slab 3 is fixed with a left shim 7, and the left side of the second composite slab 4 is fixed with a right shim 8. Then, the first connecting plate 5 is inserted into the inside of the left shim 7, and the second connecting plate 6 is inserted into the inside of the right shim 8. Since the bottom sides of the first connecting plate 5 and the second connecting plate 6 are connected to the top side of the outer wall panel 2, the left reinforcing bolt 9 and the right reinforcing bolt 10 can be tightened to ensure a stable overall connection.

[0023] The bottom ends of the inner wall panel 1 are each fixed with a lower clamping block 11, the right ends of the first composite plate 3 are each fixed with a left clamping block 12, the top ends of the outer wall panel 2 are each fixed with an upper clamping block 13, and the left ends of the second composite plate 4 are each fixed with a right clamping block 14. Multiple left clamping blocks 12 and right clamping blocks 14 are each fixed with an upper reinforcing rib 15 between them and the lower clamping block 11, and multiple left clamping blocks 12 and right clamping blocks 14 are each fixed with a lower reinforcing rib 16 between them and the upper clamping block 13. By setting multiple upper reinforcing ribs 15 and lower reinforcing ribs 16, the overall strength and rigidity can be enhanced, and the seismic performance and durability can be improved.

[0024] Left stabilizing plates 17 are fixed to the top and bottom of the left side of the first connecting plate 5, and right stabilizing plates 18 are fixed to the top and bottom of the right side of the second connecting plate 6. The top left stabilizing plates 17 and 18 are fixedly connected to the lower clamping block 11, and the bottom left stabilizing plates 17 and 18 are fixedly connected to the upper clamping block 13. By setting the left stabilizing plates 17 and 18, the wear resistance of the first connecting plate 5 and the second connecting plate 6 can be enhanced. The multiple upper reinforcing ribs 15 and lower reinforcing ribs 16 have good strength, which can further stabilize the overall connection. Moisture-proof membranes 19 are fixed to the front and rear sides of the first connecting plate 5 and the second connecting plate 6 to prevent the outer surfaces of the first connecting plate 5 and the second connecting plate 6 from getting damp, thus affecting the performance.

[0025] The left and right borrowing plates 7 and 8 are both chamfered at 20° on opposite sides to save raw materials. The outer surfaces of the left and right stabilizing plates 17 and 18 are smooth to prevent wear when the palm touches them. The first and second overlapping plates 3 and 4 are made of good materials to enhance the connection between them.

[0026] Working principle: By placing the first composite plate 3 and the second composite plate 4 between the inner wall panel 1 and the outer wall panel 2 and ensuring they fit tightly together, the first composite plate 3 is fixed with a left borrow plate 7 on the right side and the second composite plate 4 is fixed with a right borrow plate 8 on the left side. Then, the first connecting plate 5 is inserted into the inner side of the left borrow plate 7 and the second connecting plate 6 is inserted into the inner side of the right borrow plate 8. Since the bottom sides of the first connecting plate 5 and the second connecting plate 6 are connected to the top side of the outer wall panel 2, the left reinforcing bolt 9 and the right reinforcing bolt 10 can be tightened to ensure a stable connection. Furthermore, by setting multiple upper reinforcing ribs 15 and lower reinforcing ribs 16, the overall strength and rigidity can be enhanced, improving seismic performance and durability.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
