Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a steel structure for floor slab reinforcement. Background Technology

[0002] Currently, a large number of historically significant old buildings have become unusable due to various reasons, such as changes in structural use, increased load, natural disasters, and environmental erosion. The existing solution for assessing the load-bearing capacity of the building's floor slabs is to demolish the original floor slabs and rebuild them to enhance their load-bearing capacity. However, this will alter the original building's layout.

[0003] Therefore, we propose a steel structure for floor slab reinforcement, which modifies the floor slab without changing the original building layout to solve the above problems. Summary of the Invention

[0004] To address the above problems, this utility model provides a steel structure for floor slab reinforcement, including a support plate, a connecting plate, and an embedded plate, wherein the embedded plate is fixedly installed on the wall by anchor bolts;

[0005] The connecting plate is fixedly connected to the supporting plate, and the connecting plate is welded and fixed to the embedded plate;

[0006] The connecting plate is fixedly connected to the support plate by bolts.

[0007] In one embodiment of this application, the support plate is set as an HN175×90H type steel plate.

[0008] In one embodiment of this application, the connecting plate is set as a 140×80×8 steel plate.

[0009] In one embodiment of this application, the anchor bolt is configured as an M14×150 self-cutting mechanical anchor bolt.

[0010] In one embodiment of this application, the embedded plate is set as a 220×220×14 steel plate.

[0011] In one embodiment of this application, the bolt is configured as an M16 high-strength bolt.

[0012] In one embodiment of this application, the support plate has a strip-shaped hole on its side.

[0013] In one embodiment of this application, a filling layer is provided between the support plate and the floor slab, and the filling layer is made of dense concrete.

[0014] The beneficial effects of this utility model are:

[0015] 1. By fixing the embedded plate to the wall as a connector using anchor bolts, the support plate is then lifted to be flush with the bottom of the floor slab. Bolts are then used to fix the connecting plate to the support plate, followed by welding to secure the connecting plate to the embedded plate. Finally, anchor bolts are used to fix the lower part of the embedded plate, completing the installation of the support plate. This method is convenient for workers to operate and install, and the resulting structure has strong overall integrity, effectively improving the load-bearing capacity of the floor slab and enhancing the building's seismic resistance. Strengthening the load-bearing capacity of the floor slab without altering the original building layout effectively protects the original building's form.

[0016] 2. By using the slotted holes, after the support plate is installed, a filling layer is injected into the gap between the support plate and the floor slab through the slotted holes. After the filling layer solidifies, it works in conjunction with the support plate to further improve the load-bearing capacity of the floor slab.

[0017] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures pointed out in the description, claims, and drawings. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See Figures 1-4 This utility model embodiment provides a steel structure for floor slab reinforcement, including a support plate 1, a connecting plate 2 and an embedded plate 3, wherein the embedded plate 3 is fixedly installed on the wall by anchor bolts 4;

[0026] The connecting plate 2 is fixedly connected to the supporting plate 1, and the connecting plate 2 is welded and fixed to the embedded plate 3;

[0027] The connecting plate 2 is fixedly connected to the support plate 1 by bolts 5;

[0028] The support plate 1 is set as an HN175×90H type steel plate;

[0029] The connecting plate 2 is made of 140×80×8 steel plate;

[0030] The anchor bolt 4 is set as an M14×150 self-cutting mechanical anchor bolt;

[0031] The embedded plate 3 is set as a 220×220×14 steel plate;

[0032] Bolt 5 is an M16 high-strength bolt.

[0033] It should be noted that several support plates 1 are provided, and one side of the support plate 1 is attached to the bottom of the floor slab;

[0034] Several of the aforementioned support plates 1 are evenly arranged along the short side of the bottom of the floor slab.

[0035] Using the above scheme, firstly, two anchor bolts 4 are used to fix the upper part of the embedded plate 3 to the wall as a connector. Then, the support plate 1 is lifted up to be in contact with the bottom of the floor slab. Then, bolts 5 are used to fix the connecting plate 2 to the support plate 1 together. Then, the connecting plate 2 is fixed to the embedded plate 3 by welding. Finally, the lower part of the embedded plate 3 is fixed with anchor bolts 4, thus completing the installation of the support plate 1. This method is convenient for workers to operate and install. The resulting structure has strong overall integrity, which can effectively improve the load-bearing capacity and enhance the seismic resistance of the building.

[0036] In this embodiment, the support plate 1 has a strip-shaped hole 6 on its side;

[0037] A filling layer 7 is provided between the support plate 1 and the floor slab, and the filling layer 7 is made of dense concrete.

[0038] By using the above scheme, after the support plate 1 is installed, the filling layer 7 is injected into the gap between the support plate 1 and the floor slab through the strip hole 6. After the filling layer 7 solidifies, it works with the support plate 1 to further improve the load-bearing capacity of the floor slab.

[0039] The working principle is as follows: First, two anchor bolts 4 are used to fix the upper part of the embedded plate 3 to the wall as a connector. Then, the support plate 1 is lifted up to be in contact with the bottom of the floor slab. Then, bolts 5 are used to fix the connecting plate 2 to the support plate 1 together. Then, the connecting plate 2 is fixed to the embedded plate 3 by welding. Finally, the lower part of the embedded plate 3 is fixed with anchor bolts 4 to complete the installation of the support plate 1. This is convenient for workers to operate and install. The overall structure is strong and can effectively improve the load-bearing capacity and the seismic resistance of the building.

[0040] By using the slotted hole 6, after the support plate 1 is installed, the filling layer 7 is injected into the gap between the support plate 1 and the floor slab through the slotted hole 6. After the filling layer 7 solidifies, it works with the support plate 1 to further improve the load-bearing capacity of the floor slab.
