Embodiment 1

[0025] Embodiment 1, as shown in Figure 1, it is formed by the coaxial connection of three cement thin-walled pipes, wherein the ends of the thin-walled pipes located on the left and right sides have end caps, and the rest without end caps The end wall of the thin-walled tube is provided with three rectangular teeth with equal pitch and capable of meshing with each other;

Embodiment 2

[0026] Embodiment 2, as shown in Figure 2, is also formed by coaxial connection of three cement thin-walled pipes, wherein the left end of the thin-walled pipe on the left has an end cap, and the pipe wall at the right end is small on the outside and large on the inside. Conical tube; the right end of the thin-walled tube on the right has an end cap, and the tube wall at the left end is a conical tube with a large outside and a small inside; the right end of the thin-walled tube in the middle is a conical tube with a small outside and a large inside. And its left end pipe wall is the conical tube with big outside and small inside.

[0027] The manufacture method of the cement core pipe used when pouring the hollow floor slab described in embodiment 1 of the present invention:

[0028] A. Make the thin-walled tubes located on the left and right sides, unfold the outer formwork 1, and one end is provided with at least three rectangular teeth with equal tooth pitch and capable of...

Abstract

The present invention relates to a building member and its manufacture method, in particular, it is a special-purpose member for floor slab and its manufacture. In order to save building material, lighten self-weight of hollow floor slab and reduce production process and program said invention provides a cement core tube for depositing hollow floor slab, and its invented key point lies in that it is formed from at least three cement thin-wall tubes which are coaxially connected, in which only end portions of outer sides of thin-wall tubes which are positioned at left and right two sides are equipped with end cover respectively, and on the wall of thin-wall tube end portion having no end cover there is a coaxial connecting structure.

Description

technical field [0001] The invention belongs to building components and manufacturing methods thereof, in particular to special components for floor slabs and manufacturing thereof. Background technique [0002] In order to pour hollow slabs on site, people have invented cement thin-walled core pipes for filling their hollow parts, such as the notification number CN2343240, which is called concrete thin-walled cylinder members. This product is a cement thin-walled pipe with plugs at both ends. The reason for making the above structure is that the thin-walled tube is only for forming rows of hollows when pouring the hollow slab, so its strength is not required to be very high, and the function of the plugs at both ends of the thin-walled tube is only for pouring the hollow slab. , to prevent cement slurry from entering the holes in the hollow floor slab. In view of the above-mentioned structural characteristics, for the convenience of transportation and construction, it is g...
