Problems solved by technology

This method of building floor is difficult to construct by machinery, so the construction speed is slow, the labor intensity of workers is high, and safety accidents are easy to occur, and the quality of the floor is not high. It has been used in urban buildings before, but currently it is only used in rural buildings.
The second is to cast the floor slab on site, that is, while the main body of the building is being built, a full scaffolding is built from the ground or the floor of the next floor for support, the formwork is installed, the steel bars are welded, and the concrete is poured to form the floor slab. It overcomes the shortcomings of the first method, but the construction process is complex, slow, labor-intensive, and the formwork is easy to be damaged when the formwork is removed, and it is difficult to make more repeated use, unable to achieve pipeline operation
Moreover, it is necessary to build a full house of scaffolding from the ground or the floor of the next floor, so the cost is high, and it is not conducive to other constructions in the house space at the same time

Embodiment 1

[0039] as attached Figure 1~5 As shown, it is a special-shaped formwork 1 and a mold column 5 produced in a factory. as attached figure 1 Shown is a perspective view of a flat-shaped special-shaped formwork 1, which includes a forming part 1a for forming a floor slab and a first connecting part 1b and a second connecting part 1c respectively arranged on both sides of the forming part 1a, the second connecting part 1c has a The space 1d into which the first connecting part of the special-shaped formwork is inserted, of course, the space is not limited to the L-shape shown in the drawings, and can be other shapes such as V-shape or U-shape. The first connection part of the latter special-shaped formwork is inserted into the space 1d of the second connection part 1c of the previous special-shaped formwork to form a plug-in structure, and after the assembly is completed, the molding part 1e of the latter special-shaped formwork and the molding of the previous special-shaped form...

Embodiment 2

[0052] Such as Figure 10-13 As shown, the present embodiment is the specific steps of the construction method of casting the "-" shaped floor slab on site by using another structure of the mold box.

[0053] The first step is to find the fixing points of several modules 6 on both sides of the beam 8, and fix the left and right modules 6a, 6b symmetrically on the two sides of the beam 8 respectively (modules 6a, 6b can also be connected with the beam 8 when making the beam) Integral molding), and slightly higher than the upper end surface of the beam 8 (as attached Figure 10 shown);

[0054] In the second step, the two ends of the keel 7 are placed on the upper end surface of the right module 6b of a crossbeam and the left module 6a of the adjacent crossbeam, and the keel 7 is horizontal to the ground and perpendicular to the crossbeam 8 (as attached Figure 10 , 11 shown);

[0055] The 3rd step, the special-shaped formwork 1 that factory produces is close to left and rig...

Abstract

The invention discloses a construction method for casting a floor on site. The construction method comprises the following steps: the upper end surface and the lower end surface of a cross beam are respectively provided with a plurality of modules regularly distributed; the modules comprise upper modules with consistent thickness and lower modules with consistent thickness; the upper end surfaces of the upper modules are provided with a plurality of keels with holes in a lapped manner; a plurality of templates with holes are arranged closely to the lower end surface of the lower modules; the templates are filled into the plane space needing to cast the floor; corresponding holes of the templates and the keels are internally provided with bolts in a penetrating manner, and the bolts are fixed by nuts; the templates and the keels are connected into a whole so as to form an opened mold box for casting the floor on site; various concretes are added into the opened mold box for casting; and after the concretes are solidified for a period of time, the floor connected with the cross beam can be obtained by removing a mold. In the construction method, the construction process is simple, the type of the templates is single, the construction speed is fast, the labor intensity of workers is low, the mold is easy to disassemble and can be used for multiple times repeatedly. The casting-molded floor is vertical and smooth, and can be directly put into use without plastering and leveling.

Description

technical field [0001] The invention belongs to the field of construction and relates to a construction method for pouring floor slabs on site without building a full house of scaffolding for support. Background technique [0002] At present, there are generally two ways of building floor slabs: the first is the traditional way of building prefabricated slabs, that is, the prefabricated slabs that have been prepared in advance are built on the beams of the building, and then the two sides are plastered and leveled to form a floor slab. This method of building floor is difficult to construct by machinery, so the construction speed is slow, the labor intensity of workers is high, and safety accidents are easy to occur, and the quality of the floor is not high. It has been used in urban buildings before, but currently it is only used in rural buildings. . The second is to cast the floor slab on site, that is, while the main body of the building is being built, a full scaffoldi...
