Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a shear wall limb reinforcement structure with a large-sized opening. Background Art

[0002] At present, there are more and more high-rise buildings that have changed their functions. In the process of rearranging the room plan, in order to meet new standards or customer needs, it is inevitable to open window holes or door holes in the existing shear walls, which will inevitably weaken the bearing capacity of the original shear walls. Especially when the opening size is large and the remaining wall limbs on the opening side are small, the bearing capacity of the wall limbs will be seriously insufficient. At this time, in order to eliminate safety hazards, it is necessary to reinforce the shear walls with openings. Utility Model Content

[0003] Based on the above description, the utility model provides a shear wall limb reinforcement structure with a large-sized opening, which is used to reinforce the shear wall with the opening.

[0004] The utility model provides a technical solution to the above-mentioned technical problems as follows: a shear wall limb reinforcement structure with a large-sized opening includes a C-shaped steel, a tie plate and steel bars, the C-shaped steel limb is arranged on both sides of the wall limb and an adhesive is poured into the gap between the two, the C-shaped steel limb is welded through the tie plate to form a lattice column, steel bars are arranged in the wall limb and the steel bars at the opening are bent and welded together on one side.

[0005] On the basis of the above technical solution, the present invention can also be improved as follows.

[0006] As a preferred implementation manner, the ends of the wall members are roughened with concrete and then fine stone concrete is poured.

[0007] As a preferred implementation, the length of the single-sided welding of the steel bar is 10d.

[0008] As a preferred implementation, the C-shaped steel is formed by welding three steel plates through T-shaped welding.

[0009] As a preferred embodiment, the C-shaped steel reinforcement range is the full height of the opening.

[0010] As a preferred implementation, a plurality of C-shaped steel sections are evenly distributed.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0012] (1) The wall limbs use C-shaped steel as the main load-bearing component, and the steel is then welded through tie plates to form lattice columns. The structure has clear force transmission and reasonable force, which can greatly improve the bearing capacity and seismic resistance of the wall limbs;

[0013] (2) C-shaped steel is made of three steel plates welded by T-shaped welding. It can be made by factory welding, which has the advantages of fast processing, high quality, and resource conservation. It also reduces the workload of on-site welding and saves construction time.

[0014] (3) The steel plate size of the C-shaped steel can be flexibly adjusted according to the thickness of the wall, with strong applicability and easy operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0022] After a large opening is opened in the shear wall, the remaining wall members on the opening side will be smaller in size and have insufficient bearing capacity. For details, please refer to Figure 1 Based on this, the utility model provides a reinforcement structure, which is particularly suitable for reinforcing the shear wall limbs after the large-sized openings are opened, and can significantly improve the cross-sectional bearing capacity and earthquake resistance.

[0023] like Figure 2 , 3As shown, the shear wall limb reinforcement structure with a large-sized opening includes a C-shaped steel 1, a gusset plate 2 and a steel bar 3. The C-shaped steel 1 is arranged on both sides of the wall limb 4 and an adhesive is poured into the gap between the two. The C-shaped steel 1 is welded through the gusset plate 2 to form a lattice column. The wall limb 4 is provided with steel bars 3 and the steel bars 3 at the opening are bent and welded together on one side.

[0024] The utility model can significantly improve the cross-sectional bearing capacity and earthquake resistance of the wall by pasting C-shaped steel on both sides of the wall limb, welding them with gusset plates to form a lattice column, and bending the steel bars 3 at the excavated opening and then welding them together on one side. At the same time, the structure has reasonable force, simple connection structure and convenient construction.

[0025] In the utility model, Figure 1 It is shown that after a larger opening is added to the shear wall, the remaining wall members 4 on the opening side are smaller in size. Figure 2 This is a schematic elevation diagram of the reinforcement of the side wall of the opening. Figure 3 Detailed drawing of the reinforcement structure of the side wall of the opening.

[0026] For further information, see Figure 3 As shown, the end of the wall member 4 is also cast with fine stone concrete 5 after the concrete surface is roughened.

[0027] Furthermore, when drilling a hole in the shear wall, an appropriate length of the original steel bars 3 in the wall member 4 should be retained, and the steel bars 3 on both sides of the wall should be bent and welded on one side, with a welding length of 10d.

[0028] In the present invention, the C-shaped steel 1 is preferably formed by three steel plates welded by T-shaped welding, which better matches the size of the wall limb. A plurality of C-shaped steels can be evenly arranged as needed and the reinforcement range is the full height of the opening.
