Problems solved by technology

The reinforced concrete hollow slabs described in the above-mentioned open documents all use a single inner mold in the concrete. It is difficult to accurately locate a single inner mold during installation. The position of each inner mold and the relative position between inner molds will be affected by manual operation. However, large errors are generated, and the arrangement of the internal mold is irregular, which makes the internal structure of the hollow plate irregular, the physical properties are uneven and unreliable, and it is difficult to form a two-way force-bearing plate, so the mechanical performance of the structure is poor.
This shows that the construction method of existing internal mold and reinforced concrete hollow slab has following shortcoming: the one, the installation of internal mold is inconvenient, and construction work efficiency is low; ; The third is the poor physical properties of the hollow plate

Embodiment Construction

[0070] Referring to the accompanying drawings, a combined inner mold 10 of the present invention is composed of two or more modules 1 that are regularly combined and connected by connecting members 2 to form a planar structure 3 or a spatial structure 4 .

[0071] As shown in accompanying drawings 1 , 2 , 4 , and 5 , the planar structure 3 includes a single row planar structure 31 , a matrix planar structure 32 and a quincunx planar structure 33 .

[0072] As shown in Figure 2, the quincunx planar structure 33 is composed of three modules 1 or more than three modules 1 combined and connected by two groups of connecting members 2 forming an angle α, and the angle α between the two groups of connecting members 2 0-90°.

[0073] As shown in FIG. 3 , the space structure 4 is composed of three groups of connecting members 2 with an included angle α of 0-90° to connect a plurality of modules 1 into one body in the space. The arrangement of the modules 1 can be arranged regularly or...

Abstract

A combination internal mode and its engineering method, which is a planar construction or a spatial construction formed of two or more than two modules connected by jointing components regularly. Its engineering steps contain: equip template and steel bar, pay out, set combination internal mode, colligate jointing components and locate positioning bracket. It overcomes the defects that the internal mode positioning is not accurate, the inner structure of cored slab is not uniform, the bearing capability of structure is weak and the engineering efficiency is low. It can be extensively applied in reinforced concrete of building floor and wall slabs and in reinforced concrete of bridge, dam body and underground structure.

Description

technical field [0001] The invention relates to an inner mold and a construction method thereof, in particular to a combined inner mold used in reinforced concrete and a construction method thereof. Background technique [0002] The reinforced concrete hollow slab structure has been widely used in engineering because it can reduce the height of the structure and the floor of the building, and the flat bottom of the slab has excellent performance and can greatly improve the quality and function of the building. The reinforced concrete hollow slab is evacuated by the built-in inner mold to form a hollow slab. Therefore, the inner mold must be set before the reinforced concrete is poured, and steel bars or iron wires must be used to fix it during construction. The construction efficiency is low, the auxiliary materials are large, and the positioning of the inner mold is inaccurate. The internal structure of the manufactured hollow slab is irregular and the physical properties a...
