Embodiment 1

[0037] Embodiment one sees figure 1 and figure 2 A frame or frame-shear reinforcement reconstruction structure is shown, wherein each frame or frame-shear structure includes four original frame columns 1, and the tops of the original frame columns are connected with original beams and slabs 2, and this reinforcement and reconstruction structure also includes original frame columns 1 The seismic isolation device 3 implanted at the cut-off point, the additional horizontal connection member 4 connected between the columns at the cut-off point, and the additional lateral force-resistant member 5 that reinforces the additional horizontal connection member 4 .

[0038] The original frame column 1 is divided into an upper column 1.1 and a lower column 1.2 with the truncation point as a boundary, the upper side of the seismic isolation device 3 is connected to the lower side of the upper column 1.1, and the lower side of the seismic isolation device 3 is connected to the lower column...

Embodiment 2

[0043] Embodiment two see figure 1 and image 3 As shown, the difference from the first embodiment is that the additional anti-lateral force member 5 is a brace 5.1 and a shear wall 5.2. Two pieces of shear walls are arranged in the upper frame, and the four sides of the shear walls are fixedly connected with the inner side of the corresponding upper frame, and two diagonal braces are arranged in the lower frame, and the two ends of the diagonal braces are connected with the frame of the corresponding lower frame. Nodes are connected diagonally.

[0044] The shear wall is one or more of reinforced concrete shear walls, steel plate reinforced concrete shear walls, steel plate shear walls or out-of-plane constrained steel plate shear walls. In this example, it is a steel plate shear wall. The outer sides of the shear wall are fixedly connected with the inner side of the upper frame.

Embodiment 3

[0045] Embodiment three see figure 1 and Figure 4 As shown, the difference from Embodiment 1 is that the truncation is located at the upper part of the original frame column 1, and the upper frame is formed by the additional horizontal connecting members between the upper column 1.1, the original beam plate 2 and the upper column; The lower column 1.2 and the additional horizontal connecting member 4 between the lower column form a lower frame, and two diagonal braces 5.1 are arranged in the lower frame.

Abstract

Provided are a framework or frame shear reinforcement and reconstruction structure and a construction method thereof. The framework or frame shear reinforcement and reconstruction structure comprises an original framework column and an original beam plate, and further comprises an earthquake isolation device implanted in the cut-off position of the original framework column, an additional horizontal connection component for inter-column connection of the cut-off position, and an additional lateral load resisting component for reinforcing the additional horizontal connection component. The original framework column is divided into an upper column body and a lower column body with the cut-off position as a boundary. The upper side of the earthquake isolation device is connected with the lower side of the upper column body. The lower side of the earthquake isolation device is connected with the upper side of the lower column body. The additional horizontal connection component is connected between the inner side of the bottom of the upper column body and the inner side of the top of the lower column body. The additional horizontal connection component is connected with the upper column body or the lower column body in a bonded or bolted mode or through embedded steel bars or expansion bolts. By means of the framework or frame shear reinforcement and reconstruction structure, the earthquake resistance of a main structure of a house is greatly improved, the degree of damage to the main structure and non-structural components in the house is decreased, horizontal shift of the framework column in case of an earthquake is reduced, the portions, above and below the earthquake isolation device, of the framework column are limited from horizontally shifting, and the overall earthquake resistance of the framework or frame shear structure is improved.

Description

technical field [0001] The invention relates to a reinforcement structure and a construction method thereof, in particular to a modified reinforcement structure in a frame or frame-shear structure and a construction method thereof. Background technique [0002] Many existing old houses are frame or frame shear wall structures, and there are many common problems, such as the poor seismic performance of the main structure, and the poor seismic performance of non-structural objects, which are likely to cause serious damage in earthquakes. Therefore, reinforcement and reconstruction are generally required. [0003] At present, the commonly used seismic isolation reinforcement and reconstruction technology for old buildings is to cut off the middle part of the first floor column, and directly add a shock isolation pad at the cut-off place. This transformation technology has the risk of large deformation of the first floor columns during the earthquake and insufficient anti-major...
