Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and more specifically, to a reinforcement structure for existing solid brick walls. Background Technology

[0002] Brick masonry walls are constructed by stacking solid bricks. They are mainly built using solid bricks and mortar. The construction of these walls is relatively simple, which is why traditional buildings are mostly brick masonry structures.

[0003] In current construction projects, traditional solid brick walls have deteriorated over time due to disrepair. Without reinforcement and repair, they are at risk of sudden collapse, posing a safety hazard. Therefore, improvements are needed. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a reinforcement structure for existing solid brick walls, which can reinforce solid brick walls and improve the structural strength and stability of building walls.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A reinforcement structure for existing solid brick walls includes precast panels and fasteners. The precast panels are composed of several precast square panels spliced ​​together and attached to the outer surface of the wall body. Each precast square panel has several supporting feet on the side closest to the wall body. The fasteners pass through the middle of the precast square panels and fasten them to the wall body. A filling cavity is formed between the precast square panels and the wall body. The filling cavity is filled with high-performance grout to form a reinforcing grout layer. Each precast square panel has a grouting port. The filling cavities on the inner side of each precast square panel are interconnected. The connecting edges of any two adjacent precast square panels are sealed together.

[0007] Furthermore, the supporting legs of each of the precast square panels adopt a five-point support method, with each supporting leg being set at one of the four corners and the center of the precast square panel, and each supporting leg extending out of the precast square panel at one end of equal length.

[0008] Furthermore, each of the four corner support feet is pre-embedded and fixed to the prefabricated square plate using a cross-shaped steel plate.

[0009] Furthermore, the supporting feet at the center of each of the precast square panels are all made of columnar steel barrels. Each of the precast square panels has a pre-embedded hole at the center. The columnar steel barrels are pre-embedded and fixed in the pre-embedded holes. The opening of the columnar steel barrels is open on the side away from the wall body. The fasteners pass through the bottom of the columnar steel barrels and are locked and fixed to the wall body. The pre-embedded holes are filled with high-performance slurry.

[0010] Furthermore, the grouting ports on each of the precast square plates are all located at the end of the columnar steel barrel that extends out of the precast square plate, and each of the grouting ports is evenly distributed around the periphery of the columnar steel barrel.

[0011] Furthermore, each of the open ends of the columnar steel barrel is vertically extended outward and connected to a ring-shaped reinforcing plate, which is pre-embedded and fixed within the prefabricated square plate.

[0012] Furthermore, each of the prefabricated square panels is provided with a sealing strip on its periphery, and each sealing strip is provided with a pre-embedded end that is pre-embedded and fixed into the prefabricated square panel.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] 1. By setting precast slabs and fasteners, a filling cavity is formed between the precast slab and the wall body. The wall body is reinforced and strengthened by filling the filling cavity with high-performance slurry to form a reinforcing layer. The support feet on each precast square slab help to form the filling cavity of each precast square slab, and also help to improve the structural strength and support strength of each precast square slab.

[0015] 2. By setting the support feet in the middle of the precast square slab as columnar steel barrels, it is convenient to install fasteners. At the same time, the structural characteristics of the columnar steel barrels facilitate the formation and concealment of the grouting port. The installation is relatively simple. The precast square slabs are transported from the factory to the construction site and directly attached to the outside of the wall. The precast square slabs are fixed to the wall body with fasteners. Then, grout is injected into the pre-embedded holes and injected into the filling cavity through the grouting port. The construction is convenient. At the same time, the square shape of the precast slabs facilitates the alignment and adjustment of each precast square slab. Once the first precast square slab is aligned, the remaining precast square slabs can be aligned with their edges for horizontal and vertical installation. Attached Figure Description
