Problems solved by technology

The collapse of a house is generally caused by the failure of a column. The collapse and damage of a single column is likely to cause a chain reaction, which directly leads to the collapse of the entire structure.

Embodiment approach

[0035] 1. Prefabricated semi-circular plate 4: First measure the diameter of the column foundation on site, select Q345 steel, and set bolt holes on it. The positions of the bolt holes are as follows: figure 2 As shown, the hole diameter is 22mm, the inner diameter is 50-100mm larger than the column foundation, the outer diameter is 200mm larger than the inner diameter, and the plate thickness is 5mm.

[0036] 2. Prefabricated bottom plate connector 5: select Q345 steel, adopt equilateral angle steel, the specification is 30mm×30mm×4mm, and the length is 100mm. A bolt hole is set at the center of one side of the angle steel with a hole diameter of 22mm.

[0037] 3. Prefabricated annular bottom plate 11: Press the semicircular annular plate 4 and the bottom plate connecting body 5 figure 2 Placed as shown, connected by welding to form a member in which two symmetrical members are figure 2 Placed as shown, using M20 ordinary bolts to connect.

Abstract

The invention discloses an inter-pillar reinforcing structure and method for preventing a historic building from continuously collapsing. The inter-pillar reinforcing structure comprises multiple reinforcing component combinations and connection rod pieces fixedly and integrally connecting the adjacent reinforcing component combinations. Each reinforcing component combination comprises a bottom component and an upper portion component. Each bottom component comprises an annular base board, a supporting part and an annular fastener, wherein the annular base board, the supporting part and the annular fastener are sequentially connected and arranged from bottom to top. The multiple supporting parts are arranged in the peripheral directions of the annular fasteners and are in centrosymmetry relative to the annular centers of the annular fasteners. The annular fasteners are fixedly connected to the annular base boards through the supporting parts. According to the inter-pillar reinforcing structure and method for preventing the historic building from continuously collapsing, when vibrating loads are suddenly exerted from the outside, deformation of pillars is effectively controlled, the historic building is prevented from losing stability integrally, and then the historic building is prevented from continuously collapsing and being damaged; meanwhile, the reversibility degree is high, working with naked fire does not exist on the spot, operation is simple, application is convenient to carry out, and a historic building body is not damaged.

Description

technical field [0001] The invention belongs to the technical field of building reinforcement, and relates to a column reinforcement structure for preventing continuous collapse of ancient buildings. Background technique [0002] With the development of the times, urban construction is getting faster and faster, large-scale buildings, tunnels and other projects can be seen everywhere, and many projects are adjacent to ancient buildings. Since the ancient buildings have been around for a long time, most of them are masonry structures or brick-wood structures, which are sensitive to vibration due to their heavy weight. Surrounding large-scale engineering construction, especially municipal engineering, blasting engineering for subway construction, deep foundation pit excavation engineering, and large-diameter pile foundation construction all have obvious vibration characteristics and will last for a period of time. Vibration during this process may lead to the continuous colla...
