Abstract
Description
Technical Field
[0001] This utility model relates to the field of building reinforcement technology, specifically to a reinforcement structure for creating a new large opening in a load-bearing wall. Background Technology
[0002] Currently, a large number of old buildings in my country have insufficient load-bearing capacity or fail to meet functional requirements due to various reasons, such as changes in structural use, increased load, natural disasters, and environmental erosion.
[0003] When it is necessary to change the function of a room in a traditional building, it is necessary to demolish the load-bearing walls. After the load-bearing walls are demolished, the existing load-bearing wall reinforcement structure cannot effectively change the layout of the room's load-bearing walls, nor can it play the role of a concrete lintel in bearing the load. Summary of the Invention
[0004] The main purpose of this utility model is to provide a reinforcement structure for newly opened large openings in load-bearing walls, so as to improve the problems in related technologies that cannot effectively change the layout of load-bearing walls in rooms and cannot achieve the load-bearing effect of concrete lintels.
[0005] To achieve the above objectives, this utility model provides a reinforcement structure for newly opened large openings in load-bearing walls, including channel steel, angle steel for supporting the channel steel, and steel plate for supporting the channel steel.
[0006] The ends of the channel steel are welded and fixed to the angle steel and the steel plate;
[0007] The angle steel is fixed to the steel plate by welding with a steel strip.
[0008] In one embodiment of this utility model, two channel steels are provided, and the two channel steels are fixedly connected by a first tie bolt. The bottoms of the two channel steels are fixed by welding steel plate strips, and the two channel steels are arranged in the same manner.
[0009] In one embodiment of this utility model, adjacent steel plates are fixedly connected by a second tie bolt.
[0010] In one embodiment of this utility model, adjacent angle steels are fixedly connected by steel plate strips.
[0011] In one embodiment of this utility model, the distance between the angle steel and the steel plate is set to 300mm.
[0012] The steel strip is fixedly connected to the wall by anchor bolts.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By using channel steel, the top area of the opening in the wall can be supported, which can act as a lintel, making the top of the newly opened opening a whole. This can change the structure of the load-bearing wall while meeting the requirements of the wall's load-bearing capacity. By using angle steel and steel plates, the channel steel can be supported. By using the first and second tie bolts, the channel steel and the wall can be constructed as a whole, and the steel plate and the wall can be constructed as a whole, which can improve the overall strength of the newly opened opening. By welding the channel steel, angle steel and steel plate into a whole steel structure, the newly opened opening can be supported as a whole. By reinforcing it with anchor bolts and steel plate strips, the support stability of the steel structure formed by welding the channel steel, angle steel and steel plate for the newly opened opening can be effectively improved.

For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.
[0024] In addition, the term "multiple" should mean two or more.
[0025] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments. Example
[0026] Please see Figures 1-5 This utility model provides a reinforcement structure for newly opened large openings in load-bearing walls, including a channel steel 1, an angle steel 2 for supporting the channel steel 1, and a steel plate 3 for supporting the channel steel 1.
[0027] The end of the channel steel 1 is welded and fixed to the angle steel 2 and the steel plate 3;
[0028] The angle steel 2 is fixed to the steel plate 3 by welding with the steel strip 4;
[0029] Two channel steels 1 are provided, and the two channel steels 1 are fixedly connected by a first tie bolt 5. The bottom of the two channel steels 1 are welded and fixed by steel plate strip 4. The two channel steels 1 are arranged in the same way.
[0030] The adjacent steel plates 3 are fixedly connected by the second tie bolts 6;
[0031] Adjacent angle steels 2 are fixedly connected by steel plate strips 4;
[0032] The distance between the angle steel 2 and the steel plate 3 is set to 300mm;
[0033] Setting the spacing to 300mm can improve the stability of the connection between angle steel 2 and steel plate 3;
[0034] The steel plate strip 4 is fixedly connected to the wall by anchor bolts 7.
[0035] It should be noted that channel steel 1 is used to replace the lintel, and channel steel 1 is set as C22a channel steel;
[0036] Before drilling the hole, first drill a groove in the wall at the location where the channel steel 1 will be installed. Install the channel steel 1 in the groove, and use the first tie bolt 5 to pass through the wall and the channel steel 1 to fix the channel steel 1 on both sides of the wall. Then, below the channel steel 1, remove a 300-500mm high steel plate strip 4 from the wall for welding. Use the steel plate strip 4 to weld and fix the channel steel on both sides of the wall to form a stable covering structure. Next, drill grooves in the wall for installing the angle steel 2 and steel plate 3. After the angle steel 2 and steel plate 3 are installed, weld and fix them to the channel steel 1. Then, use the second tie bolt 6 to pass through the wall and the steel plate 3 to fix and connect the steel plates 3 on both sides of the wall together. Adjacent steel plates 3 and adjacent angle steel 2 are welded together by steel strip 4. Then, the steel strip 4 is cut into the wall to form a welding surface. The angle steel 2 on both sides of the wall is welded together by the steel strip 4. The steel strip 4 is fixed to the wall by anchor bolts 7. High-strength cement mortar is injected into the gaps between the channel steel, angle steel, steel plate and the wall to fill and compact the gaps. After the reinforcement is completed, the load-bearing wall at the opening to be demolished can be completely demolished. A detachable support structure is used to provide auxiliary support for the newly opened opening. After the steel structure composed of channel steel, angle steel and steel plate has been tested and has reached the design strength, the auxiliary support can be removed.
[0037] Using the above scheme, the channel steel 1 can support the top area of the opening in the wall, acting as a lintel and making the top of the new opening a whole. This can change the structure of the load-bearing wall while meeting the wall's load-bearing capacity requirements. The angle steel 2 and steel plate 3 can support the channel steel 1. The first tie bolt 5 and the second tie bolt 6 can integrate the channel steel 1 with the wall and the steel plate 3 with the wall, improving the overall strength of the new opening. By welding the channel steel 1, angle steel 2, and steel plate 3 into a whole steel structure, the new opening can be supported as a whole. The anchor bolts 7 and steel plate strips 4 are used for reinforcement, which can effectively improve the stability of the steel structure formed by welding the channel steel 1, angle steel 2, and steel plate 3 for supporting the new opening.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
