Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the embodiment of the present application provides a core mold for a hollow floor suitable for a high temperature environment, including a box body 1 having a hollow cavity, the upper surface and the lower surface of the box body 1 are respectively formed with a plurality of water receiving grooves 3 by recessing, and further including a structural column 2 penetrating the upper surface and the lower surface of the box body 1, the structural column 2 is provided in a plurality of, a plurality of the structural columns 2 are arranged in an array along the length direction of the box body 1.

It should be noted that the box body 1 is rectangular, and the length direction is the length direction of the rectangular parallelepiped.

In the mode, the water receiving groove 3 is formed in the box body 1, during construction, the core mold is laid on the template of the hollow floor system, the water receiving groove 3 is upward and kept in a horizontal state, water can be sprayed towards the core mold when one or more core molds are laid, water flow can be gathered in the water receiving groove 3, and the core mold is cooled, so that the core mold is not prone to deformation due to high temperature, the structural strength is good after concrete is poured, the structural strength of the core mold is further enhanced through the arrangement of the structural columns 2, and the construction quality is effectively improved.

Specifically, the structural column 2 comprises a first stepped column groove 21 formed along the upper surface of the box body 1 in a concave manner, a second stepped column groove 23 formed along the lower surface of the box body 1 in a concave manner, and a supporting part 22 fixedly connected between the first stepped column groove 21 and the second stepped column groove 23, wherein the first stepped column groove 21, the second stepped column groove 23 and the supporting part 22 are on the same axial line.

In the above mode, the column diameters of the first stepped column groove 21 and the second stepped column groove 23 are gradually decreased toward the supporting portion 22, so that the pressing stress of the concrete is gradually dispersed, and the longitudinal supporting force of the box body 1 can be improved, and in the using process, the accumulated water for cooling is collected in the first stepped column groove 21 or the second stepped column groove 23, the volume of the accumulated water is larger, the better the heat dissipation effect is, the closer the distance between the box body 1 and the sunlight is, the larger the heat is, the heat dissipation directions of the first stepped column groove 21 and the second stepped column groove 23 are matched, so that each longitudinal position in the first stepped column groove 21 or the second stepped column groove 23 can keep a uniform temperature, and the solidification of the concrete is more stable.
