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.

[0043] like Figure 1~Figure 4 As shown, the structural relationship is as follows: an earthquake-resistant building structure reinforcement device, corresponding to the position support of the floor beam, is arranged between the upper floor and the lower floor, including a fixed bottom plate 2, a column 4 and a positioning plate 6;

[0044] The bottom plate 2 and the positioning plate 6 are respectively fixed to the top of the lower floor and the bottom plate of the upper floor, and each column 4 is vertically arranged between the bottom plate 2 and the positioning plate 6; the bottom end of the column 4 is plugged and installed with the bottom plate 2, and a vertical sliding pair is formed between the two; the sliding pair provides a certain degree of vertical yielding property in the structure for the reinforcement device, which can partially eliminate the structural internal stress generated by the building structure under the action of factors such as earthquake vibration, and improve the stability of the structure;

[0045] The top end of the column 4 is connected with the top plate 7 by sliding fit, and a horizontal sliding pair is formed between the two along the length direction of the top plate 7. The sliding pair provides adjustability for the installation and construction of the reinforcement structure to adapt to the deviation between the actual relative installation position of the bottom plate 2 and the positioning plate 6 and the designed relative installation position caused by construction errors and other reasons in actual construction.

[0046] Preferably, it also includes an earthquake-resistant structure 3;

[0047] The bottom end of the column 4 is connected with the earthquake-resistant structure 3, and is plugged and installed with the bottom plate 2 through the earthquake-resistant structure 3;

[0048] The earthquake-resistant structure 3 has adaptive yielding flexibility for buffering and shock absorption. The earthquake-resistant structure 3 can buffer, weaken and absorb the vibration in the reinforced structure, which is conducive to further improving the stability of the reinforced structure.

[0049] Preferably, the earthquake-resistant structure 3 includes a shell 31, an elastic structure and a plug-in block 33;

[0050] The outer shell 31 is a hollow columnar structure with an opening at the upper end, and an elastic structure is provided at the inner bottom thereof. The lower end of the column 4 is inserted into the outer shell 31 through the opening at the upper end of the outer shell 31 to press the elastic structure downwards.

[0051] In actual setting, the elastic structure can be a rubber column or a spring column;

[0052] A downwardly protruding plug-in block 33 is disposed at the center of the lower end of the housing 31 , and a plug-in slot 21 is correspondingly disposed at the top of the bottom plate 2 , and the plug-in block 33 is plugged into the plug-in slot 21 .

[0054] The rib 32 improves the stability of the plug-in connection between the plug-in block 33 at the bottom of the shell 31 and the plug-in groove at the top of the base plate 2. Without affecting the vertical yielding property provided by the sliding pair between the two, it limits the relative rotation of the seismic resistant structure 3 and the base plate 2, thereby preventing the seismic resistant structure 3 and the column 4 from tipping over.

[0055] Preferably, it also includes a slider 5;

[0060] Preferably, it also includes a top plate 7 with mounting columns 71 fixed on the top;

[0061] The top plate 7 is fixedly connected to the positioning plate 6 through the connecting columns, and the mounting columns 71 are connected to the upper floor slab to fix the positioning plate 6 to the upper floor slab;

[0062] During actual construction, the mounting column 71 can be connected and fixed to the upper floor slab by angle steel and bolts;

[0063] An oblique support rod obliquely supported between the positioning plate 6 and the top plate 7 is also provided between adjacent connecting columns.

[0064] The positioning plates 6 and the top plate 7 enable the columns 4 to form a support for the overall structure, dispersing the gravity of the upper floor slab to the columns 4 via a plurality of mounting columns 71, thereby avoiding excessive stress on some columns 4 due to independent support of the columns 4, and facilitating the stability of the overall structure of the building.

[0065] Preferably, stirrups 8 are also included;

[0066] The column 4 is provided with stirrups 8 in a circle around its outer periphery.

[0067] The stirrups 8 are used to improve the structural strength of the column 4 and can reduce or even eliminate the radial outward deformation of the column 4 under the vertical pressure mainly caused by gravity.

[0068] Preferably, it also includes a base 1;

[0069] The base 1 is fixed to the bottom of the base plate 2 and connected to the lower floor plate by nuts and bolts, so that the base plate 2 and the lower floor plate are installed and fixed.

[0070] In actual configuration, the base 1 can be welded or integrally formed to the bottom of the base plate 2 .

[0071] The specific installation process includes the following steps:

[0072] In the first step, the base 1 is connected to the lower floor slab at the designed installation position by nuts and bolts to realize the installation and fixation of the base plate 2; then, the plug-in block 33 of the seismic-resistant structure 3 is inserted into the plug-in groove 21 at the top of the base plate 2, and the bottom end of the column 4 is installed and connected to the seismic-resistant structure 3, so that the bottom end of the column 4 is against the top of the elastic structure, and then the slider 5 is threadedly installed on the screw 41 fixed on the top of the column 4 through the threaded hole at the bottom thereof.

[0073] In the second step, the positioning plate 6 and the top plate 7 with the mounting columns 71 fixed on the top are connected and fixed into an integral structure through connecting columns and diagonal bracing rods.

[0074] In the third step, the T-shaped convex strip structure at the bottom of the positioning plate 6 is inserted into the groove opened on the top of each slider 5, so that a horizontal sliding pair is formed between the positioning plate 6 and each slider 5 along the length of the positioning plate 6, and the sliding pair is used to slide and adjust the overall structure formed by the connection between the positioning plate 6 and the top plate 7 to the designed installation position.

[0075] The fourth step is to connect and fix the installation column 71 to the upper floor slab by angle steel and bolts to complete the construction.
