Embodiment 1

[0029] Such as Figure 1 to Figure 3 As shown, a honeycomb core structure includes a honeycomb core body, an annular ring groove 4 is also provided on the side of the honeycomb core body, and the honeycomb core body is spliced ​​by an upper box body 2 and a lower box body 3 , and after the splicing of the upper box body 2 and the lower box body 3 is completed, the formed seam 6 is located at the bottom of the ring groove 4;

[0030] It also includes a filling layer filled in the joint 6, and the filling layer is formed of an adhesive material or is a sealing pad.

[0031] Specifically, the above annular groove 4 is a groove provided on the side of the honeycomb core body for embedding the steel wires constraining the position of the honeycomb core on the floor. When prefabricating the honeycomb core of the existing monolithic structure, since the corresponding mold needs to have a deformation part corresponding to the ring groove 4, there are complex procedures, complex mold ...

Embodiment 2

[0035] Such as Figure 1 to Figure 3 As shown, this embodiment is further limited on the basis of Embodiment 1: in order to ensure the connection strength between the upper box body 2 and the lower box body 3, and avoid the filling layer butt joint 6 of the honeycomb core structure during the transfer and hoisting process. The sealing performance fails, the upper box body 2 and the lower box body 3 are provided with steel mesh 5, and the steel mesh 5 of the upper box body 2 and the lower box body 3 are welded at the joint 6 position. As a person skilled in the art, the above steel mesh 5 is composed of reinforcement bars sandwiched in the bottom plate, top plate or side plate of the upper box body 2 or the lower box body 3, and is arranged in the above welding connection form, which can avoid 6 joints The joint surface of the honeycomb core structure is subjected to excessive tension during the transfer and hoisting of the honeycomb core structure.

[0036] As a structural sc...

Embodiment 3

[0043] This embodiment is further limited on the basis of any one of the technical solutions provided by any one of the above embodiments, such as Figure 1 to Figure 3 As shown, in order to avoid stress concentration at the position of the annular groove 4 when the honeycomb core structure is stressed, the cross section of the annular groove 4 is semi-elliptical or semicircular.

[0044] In order to improve the fire-resistant performance of the honeycomb core structure, refractory materials are laid on the outer surfaces of each surface of the honeycomb core body.

Abstract

The invention discloses a honeycombed-core structure. The honeycombed-core structure comprises a honeycombed-core body. The side surface of the honeycombed-core body is further provided with an annular ring groove. The honeycombed-core body is formed by splicing an upper box body and a lower box body, and after splicing of the upper box body and the lower box body is completed, a formed joint is located in the bottom of the ring groove. The honeycombed-core structure further comprises a filling layer which fills the joint. The packing layer is formed by bonding materials or sealing pads. The honeycombed-core structure is convenient to manufacture and high in finished product ratio.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a honeycomb core structure. Background technique [0002] Among the existing building forms, the honeycomb core floor has the following advantages: first, it is convenient for construction, and the mandrel can be placed directly, reducing the amount of concrete, shortening the maintenance time, and can also speed up the construction progress and shorten the construction period; second, it has good bearing performance , suitable for large spans; the third is that when the same bearing capacity is achieved, less concrete and other materials are used, so its own weight is also small, the economy is better, the plate thickness is thinner than other structures, and the net height of the floor can be increased; the fourth is relative Compared with other rib beam structures, the bottom plate makes the honeycomb core floor flat and beautiful; fifth, it has good sound insulation and heat...
