Description

Technical Field

[0001] The utility model belongs to the technical direction of building construction, and particularly relates to a reinforcement structure for adding door and window openings to an existing masonry wall. Background Technique

[0002] With the progress of society and the increasing improvement of people's living standards, many early masonry structures can no longer meet people's living and usage requirements. When the original masonry structure is renovated and the original layout needs to be adjusted, door and window openings will be opened in the original masonry wall. Since the masonry wall belongs to a heavy wall structure, opening holes in the masonry wall will cause the bearing capacity of the original masonry wall to decrease. When opening holes, it is necessary to reinforce the door and window openings. The conventional method is to adopt the form of adding concrete lintels and door and window boundary columns. This form has cumbersome construction procedures, great damage to the original structure, and potential safety hazards, and consumes high labor costs, capital costs, and time costs. Therefore, there is an urgent need for a reinforcement structure for adding door and window openings to an existing masonry wall to solve the above-mentioned problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a reinforcement structure for adding door and window openings to an existing masonry wall for the existing device to solve the problems put forward in the above background technique.

[0004] To solve the above technical problems, the utility model provides the following technical solution: A reinforcement structure for adding door and window openings to an existing masonry wall, including an existing brick masonry wall. Three reinforcement steel plates are respectively arranged on the outer wall of the existing brick masonry wall. A plurality of steel washers are arranged on the outer wall of the reinforcement steel plate. A nut is arranged on the outer wall of the plurality of steel washers. A tension bolt is arranged inside the nut. A flat weld is arranged between the three reinforcement steel plates.

[0005] Furthermore, the reinforcement steel plate is a U-shaped steel plate, and a plurality of through holes matched with the tension bolt are arranged on the outer wall of the reinforcement steel plate, which facilitates the fastening of the reinforcement steel plate.

[0006] Furthermore, the steel washer is in an annular structure, and the inner diameter of the steel washer is larger than the outer diameter of the tension bolt, which facilitates the lining of the nut through the steel washer.

[0007] Furthermore, the nut is in a regular hexagon structure, and the nut meshes with the tension bolt, which facilitates the fastening of the tension bolt through the nut.

[0008] Furthermore, the three reinforcement steel plates are connected by flat welds, and the three reinforcement steel plates are distributed in a "冂" shape, which facilitates the welding and fixing of the three reinforcement steel plates.

[0009] Compared with the prior art, the beneficial effects achieved by the utility model are: For the utility model,

[0010] (1) By setting up existing brick masonry walls, reinforced steel plates, steel gaskets, nuts, tension bolts and flat welds, the advantages of short construction period, convenient construction and high safety are achieved, thereby solving the problem of serious damage to the original structure and avoiding safety hazards during construction. At the same time, it effectively solves the problems of high labor costs, capital costs and time costs, meets people's work needs, and is worthy of promotion and use.

[0017] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides a technical solution: a reinforcement structure for newly added door and window openings in an existing masonry wall, comprising an existing brick masonry wall 1, an existing brick masonry wall 1, and the outer walls of the existing brick masonry wall 1 are respectively provided with three reinforcing steel plates 2, the outer walls of the reinforcing steel plates 2 are provided with a plurality of steel gaskets 3, the outer walls of the plurality of steel gaskets 3 are provided with nuts 4, the inner walls of the nuts 4 are provided with tension bolts 5, and flat welds 6 are provided between the three reinforcing steel plates 2.

[0019] Furthermore, the reinforcing steel plate 2 is a U-shaped steel plate, and a plurality of through holes matching with the tension bolts 5 are formed in the outer wall of the reinforcing steel plate 2, which facilitates the fastening of the reinforcing steel plate 2.

[0020] Furthermore, the steel gasket 3 is of an annular structure, and the inner diameter of the steel gasket 3 is larger than the outer diameter of the tension bolt 5, which facilitates the padding of the nut 4 through the steel gasket 3.

[0021] Furthermore, the nut 4 is of a regular hexagon structure, and the nut 4 meshes with the tension bolt 5, which facilitates the fastening of the tension bolt 5 through the nut 4.
