Description

Background Art

Most of the existing building earthquake-proof modules are pure modular structures connected by beams and columns. The bearing capacity, deformation and energy dissipation capacity of the connection nodes within the modules are insufficient, and it is difficult to meet the performance requirements of high-rise modular steel structures for connection nodes. However, my country's earthquake-resistant fortification requirements are very strict, so pure modular structures can only be used in low-rise buildings in my country.

In addition, in the multi-module system, due to the lack of construction and installation space, the connections between modules are all hinged or semi-rigid connections, such as bolt connections, which makes the energy-absorbing components vertically discontinuous. Due to the vertical discontinuity of the energy-absorbing components between modules, their energy-absorbing capacity depends on the reliability of the nodes, which in turn increases the demand for the bearing capacity of the nodes.

FIG1 is a schematic diagram of a building shock-absorbing module structure of the prior art, which is a pure module structure connected by beams and columns. The bearing capacity, deformation and energy dissipation capacity of the connection nodes in the module are insufficient, and it is difficult to meet the performance requirements of the connection nodes of high-rise modular steel structures. The inventor arranges lateral load supports in the existing modules, which can effectively bear the lateral forces caused by earthquakes.

Please refer to Figures 1 to 3 together. An all-steel module 100 for a high-rise building according to an embodiment of the present invention includes a module beam 10, a module column 20, and a lateral load support member 30. The module beam 10 extends in the horizontal direction, and the module column 20 extends in the vertical direction. The module beam 10 and the module column 20 are welded to form a cube. In other embodiments, the module beam 10 and the module column 20 can also be fixedly connected by other means such as riveting or bolts. The cube has six vertices and six surfaces. According to the orientation of Figure 1, the six surfaces are upper and lower surfaces, front and rear surfaces, and left and right side surfaces. The lateral load support member is located on the surface of the cube, and one end of the support member is fixed at a vertex of the cube, and the other end is fixed to the module beam 10 or the module column 20. Preferably, there are two support members, and they are respectively located on different surfaces of the cube. As shown in Figure 2, the two ends of the lateral load support member 30 can be respectively fixed at the two vertices of the diagonal line of the surface, or as shown in Figure 3, the two ends of the lateral load support member 30 are respectively fixedly connected to the two opposite module columns 20.

In this embodiment, a lateral load support member 30 is arranged in an existing module, and the module beam 10 and the module column 20 are welded into a cubic module, and the support member is arranged on different surfaces of the cube, so as not to occupy the space inside the high-rise building all-steel module 100. One end of the lateral load support member 30 is fixed at a vertex of the cube, and the other end is fixed to the module beam or the module column, so that the lateral load support function can be effectively exercised to bear the lateral force generated by the earthquake.

In a further embodiment, the lateral load support member is divided into a first support member 31 and a second support member 32. The first support member 31 and the second support member 32 are located on different surfaces of the cube so as to perform anti-buckling functions at different positions. Among them, one end of the first support member 31 is fixed to a vertex of the cube, and the other end is fixed to the module beam 10 opposite to the vertex. Preferably, in this embodiment, the two ends of the first support member 31 are respectively fixed to the two vertices of the diagonal of the surface where they are located, so as to respectively support the relative module beams 10 and module columns 20, form an integral diagonal brace column, and better perform the anti-buckling support function. The two ends of the second support member 32 are respectively fixedly connected to the two relative module columns 20 to form a shear wall to perform the anti-buckling support function. Therefore, the main lateral force caused by the earthquake can be better borne by the combined action of the first support member 31 and the second support member 32.

Specifically, the module beam 10 includes a first module beam 11 and a second module beam 12. The length of the first module beam 11 is greater than the length of the second module beam 12. It can be understood that there are four first module beams 11, second module beams 12 and module columns 20, and each first module beam 11 has the same length, each second module beam 12 has the same length, and each module column 20 has the same length. Each vertex of the cube is connected to a first module beam 11, a second module beam 12 and a module column 20 respectively. In architectural design, the front and rear surfaces are usually used as load-bearing walls, and the left and right side surfaces are used for opening doors and windows. Preferably, the first support member 31 and the second support member 32 are respectively arranged on the front and rear surfaces where the first module beam 11 is located. In this embodiment, the first support member 31 is located on the front surface. Correspondingly, the second support member 32 is located on the back surface. In other embodiments, the first support member 31 and the second support member 32 can also be respectively arranged on the upper and lower surfaces or the left and right side surfaces.

Preferably, the second support member 32 is arranged in parallel with the first form beam 11 to further strengthen the lateral load resistance of the two module columns 20 connected thereto. Referring again to FIG. 3 , it is further preferred that two second support members 32 are arranged at intervals, and a wall panel 33 is arranged on the surface where the second support member 32 is located, and the wall panel 33 is respectively connected to the first form beam 11 and the two second support members 32, preferably covering and supporting the entire rear surface in the longitudinal direction, thereby forming an integral shear wall with greater support strength on the rear surface. Preferably, the wall panel 33 is a steel plate.

As shown in FIG. 4 , as another embodiment of the present invention, a high-rise building all-steel module 100, wherein the first support members 31 are two connected end to end. The two first support members 31 are connected to a first mold beam 11 on the surface to form a triangle. Preferably, the first mold beam 11 serves as the base of the triangle. The connection point of the two first support members 31 is located on another first mold beam 11 on the surface, that is, the two first support members 31 form a built-in herringbone support on the front surface, making it particularly suitable for a high-rise building all-steel module 100 with a large transverse span. Further preferably, as shown in FIG. 5 , a middle column 34 parallel to the module column 20 is provided at the connection intersection of the two first support members 31. In addition, a middle column 34 is also provided at the corresponding position of the rear surface, so that the two middle columns 34 and the four module columns 20 together form a 6-column built-in support system, further enhancing the rigidity and bearing capacity of the high-rise building all-steel module 100.

As shown in Figures 6 to 10, an energy dissipation, vibration reduction and lateral force resistance system of one embodiment of the present invention is formed by stacking two or more all-steel modules 100 of high-rise buildings. Among them, two adjacent module columns 20 are connected by a connector 40, and the module column 20 is in a hollow column shape. The connector 40 includes at least two inner sleeves 41, and the two inner sleeves 41 are respectively inserted into the inner walls of the upper and lower module columns 20. The side of the inner sleeve 41 is provided with an inner stud protruding outward, and the inner wall of the module beam 10 and the module column 20 is provided with an outer stud protruding inward, and grouting material is arranged between them. The grouting material fixes the adjacent module columns 20 and the connector 40. Because the inner studs and the outer studs are arranged in an alternating manner, the load distribution between the inner sleeve 41 and the module column 20 and the module beam 10 is more uniform after fixation, and the fixing effect is more reliable.

The energy dissipation, vibration reduction and lateral force resistance system 200 using the inner sleeve 41 grouting connection according to the present invention adopts a simple structure to enhance the stability of the connection between steel structures. The connector 40 is simple and quick to manufacture, and does not require a large operating space to be reserved near the connection part when manufacturing the connection, and does not require welding operations. It has low technical requirements for the installer and a large error tolerance range, thereby saving costs and improving building quality, and is very suitable for promotion and use in various building application fields.

Due to the existence of the double-module beams 10 adjacent to each other in the system 200, the vertical force transmission of the diagonal bracing columns and the shear walls is discontinuous. Further preferably, in this embodiment, the two module beams 10 adjacent to each other are fixed together by bolts, so that the modules 100 are stacked to form a vertically continuous lateral force resistance system 200, which can further improve the seismic performance of the entire system 200. Therefore, the rigidity of the upper and lower modules can be ensured by combining the composite beams and the connectors 40, and the combination of the integral diagonal bracing columns and the integral shear walls is the key to the application of the energy dissipation and vibration reduction lateral force resistance system 200 of the present invention to high-rise buildings.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
