Description

Technical Field

[0001] The invention relates to the technical field of building shock absorption, in particular to a shock absorption and energy dissipation structure for building column tops. Background Art

[0002] The top of a building column is the connection point between the column and the superstructure. It is responsible for transferring the load of the superstructure to the column and ultimately to the foundation. In order to improve the seismic performance and stability of the building under dynamic loads (such as earthquakes, strong winds, etc.), a shock-absorbing and energy-dissipating structure is installed at the top of the column.

[0003] At present, the column top shock-absorbing and energy-dissipating structure usually only has energy-dissipating and shock-absorbing parts, such as dampers, set between the column top and the upper structure. Its energy-dissipating and shock-absorbing capacity is limited. In order to ensure the stability of the overall structure, energy-dissipating and shock-absorbing is usually only performed in the vertical or horizontal direction. If the energy-dissipating and shock-absorbing capacity of the structure is to be improved, the stability of the overall structure will be reduced accordingly, especially for buildings with a conical top on the column top. Because the overall stability of the conical top structure is relatively low compared to the flat structure, it is more difficult to improve the energy-dissipating and shock-absorbing capacity of the structure, and correspondingly it is difficult to improve the wind and earthquake resistance of the building. Summary of the invention

In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The supporting frame 1 is a triangular structure, and the supporting frame 1 is distributed in a rectangular shape, such as Figure 1 As shown, a total of four support frames 1 in front, back, left and right and a central top 2 together constitute an upper base of a cone-shaped structure, the top wall is installed on the upper base to form a cone-shaped roof and the roof as a whole has high stability, the columns 4 and the shock absorbers 3 are distributed in a rectangular shape, and the shock absorbers 3 are respectively located between adjacent support frames 1, as shown in FIG. Figure 1 As shown, the shock absorbing body 3 connects the upper base and the column 4 at four corner points, which can effectively reduce or eliminate the force transmission between the upper base and the column 4, and improve the shock absorption and energy dissipation capacity of the building.

[0022] See also Figure 1 , Figure 2 and Figure 3The intermediate connecting body 5 includes a first connecting body 52 provided with an inclined support surface 51 and a second connecting body 54 provided with an inclined limiting surface 53. The first connecting body 52 is fixedly connected to the column 4, and the second connecting body 54 is fixedly connected to the first connecting body 52 through a fastener. The inclined support surface 51 and the inclined limiting surface 53 are both provided with an elastic pressing body 55. The inclined support surface 51 provides limiting support for the support frame 1 from the inside, such as Figure 2 As shown, each first connector 52 is provided with two inclined support surfaces 51, and supports and limits two adjacent inclined support frames 1 from the inside, and each first connector 52 is provided with four inclined limiting surfaces 53, and the four inclined limiting surfaces 53 limit the support frame 1 from the outside and the side edges opposite to the adjacent inclined support frames 1, and the inclined limiting surfaces 53 and the inclined support surfaces 51 together constitute a limiting constraint area, and the limiting constraint area corresponds to the corner point below the support frame 1 one by one, as shown in FIG. Figure 1 As shown, the limiting constraint areas at the two corner points below the support frame 1 constrain the range of movement of the support frame 1 in three directions: horizontally, longitudinally and vertically. Under normal conditions, the elastic abutment 55 combines with the limiting constraint area to firmly limit the support frame 1, so that the upper base is in a stable state. Under dynamic loads, the combination of the elastic abutment 55, the limiting constraint area and the shock absorbing body 3 forms an efficient shock absorbing system between the upper base and the column 4, which effectively increases the energy dissipation and shock absorbing capability of the overall structure. The elastic abutment 55 can be a rubber block.
