Problems solved by technology

Therefore, when the first layer is selected as the embedded layer, the horizontal load and wind load of the earthquake cannot be effectively transmitted.
The conventional practice is to lower the embedded end of the structure to the basement floor or basement floor where the horizontal force can be effectively transmitted, but the calculation height of the structure will increase accordingly, which is not conducive to the structural force and the economy of the project
To solve this problem, LUD (speed locking device) can be installed to transmit horizontal force, but because the LUD device used in the market has problems such as high installation accuracy requirements, high price, and difficult maintenance, this device cannot be applied to all projects

Embodiment 1

[0043] Such as Figure 1 to Figure 4 As shown, the present invention discloses a sand tank connection node structure for the free surface of a basement, including a central basement 1, at least one side of which is the free surface adjacent to the corresponding side basement 2 , expansion joints 3 are provided between each floor 1-1 of the central basement 1 and floors 2-1 of the same number of floors in the side basement 2, wherein the central basement 1 and the side basement 2 Floors with the same number of floors can be of the same height, for example figure 2 As shown in Part B of the figure 2 as shown in Part A of ;

[0044] The first floor slab 1-1A of the central basement 1 is connected with the first floor slab 2-1A of each side basement 2 corresponding to the free surface by a sand tank structure.

[0045] The sand tank structure includes a first basement edge beam 1-2 and a second basement edge beam 2-2, and the four sides of the outer side of the first basement...

Embodiment approach

[0061] Such as image 3 As shown, any one or more of the first basement edge beam 1-2 and the second basement edge beam 2-2 adopts a heightened edge beam structure, and the heightened edge beam structure is from bottom to top It is composed of edge-banding beam body a, precast and added high-rise b and cast-in-place added high-rise c, wherein, the edge-banding beam body a adopts the original design size when the basement is not provided with the sand tank connection node structure, and the existing The poured high-rise c is flush with the top plate 1-2-1A of the first coaming plate 1-2-1 and the top plate 2-2-1A of the second coaming plate 2-2-1, during construction , first bind the heightened edge banding beam structure and steel bars of the coaming, and then pour the edge banding beam body a, precast high-rise b, the bottom plate 1-2-1B of the first coaming 1-2-1 and the second coaming 2-2-1's bottom slab 2-2-1B concrete, then fill the joint cavity with sand 4 after the con...

Embodiment 3

[0067] On the basis of the above-mentioned embodiment 1 or embodiment 2, this embodiment 3 also adopts the following preferred implementation modes:

[0068] Such as figure 2 As shown, one or more non-first floor floors 1-1B of the central basement 1 and one or more non-first floor floors 2-1B of the side basement 2 corresponding to the free surface pass through The sand tank structure is connected.

[0069] Therefore, the horizontal force transmission capacity of the central basement 1 and the side basement 2 at the place where the sand tank structure is installed can be enhanced; where the sand tank structure is used to connect, the horizontal force can be calculated according to the actual condition and force of the free surface of the project. Determine the size of the load.

Abstract

The invention discloses a sand groove connecting node structure for a free face of a basement. The sand groove connecting node structure is characterized in that a first floor of a central basement is connected to a first floor of a side basement corresponding to each free face through a sand groove structure, so that under a normal working condition with only temperature change, temperature difference deformation release between the central basement and the side basements is achieved, and horizontal force can be transmitted between the central basement and the side basements in a reciprocating mode under the abnormal working conditions of earthquakes and strong wind; moreover, the sand groove structure has no influence on the functions of the basement and the ground building thereof, and the first floor of the basement can be used as a built-in layer of the ground building; and in addition, the sand groove structure is high in mounting precision, simple to mount and operate, easy to construct on site, low in material cost and free of additional mechanical devices, and has the advantages of being simple in later maintenance and outstanding in economic benefit.

Description

technical field [0001] The invention relates to a connection node structure of a basement, in particular to a connection node structure of a sand tank used for the empty surface of the basement. Background technique [0002] Due to the shortage of land in the city, it often happens that the first floor of the basement of the project is an empty surface, that is, there is no buried depth of the soil layer, for example figure 1 As shown, one side of the central basement 1 is adjacent to the side basement 2, which is an air-facing condition, and the other side of the central basement 1 is a soil-facing condition connected to the soil layer. Therefore, when the first layer is selected as the embedded layer, the horizontal load and wind load of the earthquake cannot be effectively transmitted. The conventional practice is to lower the embedded end of the structure to the basement floor or basement floor where the horizontal force can be effectively transmitted, but the calculate...
