Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] refer to figure 1 , the present invention provides a compressible joist for cast-in-place formwork at the seams of assembled prefabricated slabs, which is used to solve the problem that when the assembled prefabricated slab is connected through the cast-in-place section, the cast-in-place section will be disconnected from the bottom of the precast slab There is a height difference, which leads to the inability to support uniformly, which makes the construction consume labor and materials, and also increases the construction steps and affects the construction efficiency. The compressible joist of the present invention is used to support the bottom of the prefabricated slab and the cast-in-place section. For the formwork at the cast-in-place section, the compressible joist can press the formwork into the interior of the joist by adjusting ...

Abstract

The invention relates to a compressible joist for a cast-in-place formwork of an abutted seam of fabricated precast slabs and a construction method. The compressible joist comprises a supporting structure, an adjusting structure and an elastic slab, wherein the supporting structure internally forms an adjusting space, two end slabs convexly extend out of a top slab to form an extending section in a corresponding mode, the adjusting structure is installed in the adjusting space, is compressible and comprises a supporting rod penetrating through the top slab, and the elastic slab is fixedly connected to the supporting rod and is supported through the adjusting structure to be located above the top slab; the elastic slab is squeezed to move in the direction of the top slab, so that the adjusting structure is compressed and deformed, and a deformation space with a preset height and for containing a template of the cast-in-place formwork is formed by defining the upper surface of the elastic slab and the extending section; and by adoption of the compressible adjusting structure, the template can be pressed into the compressible joist, the problem that in the prior art, the height difference exists due to the template is solved, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a compressible joist for cast-in-place formwork at joints of assembled prefabricated slabs and a construction method thereof. Background technique [0002] With the development of modern industrial technology, building houses can be manufactured in batches like machine production, as long as the prefabricated house components are transported to the construction site and assembled. [0003] For the construction of prefabricated buildings, the connection between prefabricated components is particularly important. Currently, in-situ concrete is usually used to realize the connection between prefabricated components. Take the assembly of prefabricated slabs as an example to illustrate, place two prefabricated slabs at the corresponding floor positions, leave a certain distance between the two prefabricated slabs to form joints, and pour on the top surface of the prefabricated sla...
