Embodiment Construction
[0021] Such as figure 1 Shown is a schematic structural view of the open box 31 of the present invention. The open box is made of glass fiber reinforced cement, and is an open box body composed of side walls and bottom plates. The open box 5 is a GRC product, which plays the role of the side form of the cast-in-place reinforced concrete rib beam 1 during the concrete pouring process, and supports the lattice steel bar laminated plate 4 and the construction load. The bottom plate of the box body is exposed and used as the building roof , so the good durability of GRC products is closely related. The open box 31 can be a single-section type, such as figure 2 shown, can also be multi-section, formed by assembly, as in image 3 and Figure 4 As shown. If it is a multi-section type, they are fixed by splicing each other through snap buttons. The height of the multi-section assembled box mold can pursue a higher height, which cannot be achieved by a single section. Compared w...

The invention relates to a floor slab, in particular to a cast-in-place concrete hollow floor slab internally provided with an assembled box template combining prefabrication with cast-in-place. The cast-in-place concrete hollow floor slab comprises a reinforced concrete rib beam (1), a reinforced concrete overlapping layer (2) and an assembled box template (3), wherein the reinforced concrete rib beam (1) is formed by in-situ casting between the adjacent assembled box templates (3), the reinforced concrete overlapping layer (2) is arranged above the assembled box template (3) and is formed by in-situ casting, the reinforced concrete overlapping layer (2) and the reinforced concrete rib beam (1) form a T-shaped stress section; the assembled box template (3) is provided with a sealed cavity structure and is the inner mould of the floor slab, and a closed large cavity structure of the floor system is formed together with the reinforced concrete rib beam (1) and the reinforced concrete overlapping layer (2). The structural height of the floor slab can be greatly reduced; under the circumstance of same floor height, a relatively higher building use space can be provided; moreover, the bottom of the integral floor slab is flat, and the floor slab is convenient to use.
Description
technical field [0001] The present invention relates to a floor slab, more specifically, to a built-in assembled box formwork cast-in-place concrete hollow floor slab combined with prefabrication and cast-in-place Background technique [0002] With the rapid development of my country's economic construction, reinforced concrete structures have been widely used in industrial and civil buildings, and have achieved good technical and economic results. Due to the requirements of high-rise, large space and earthquake resistance in buildings, many new structural systems with good technical and economic effects have been developed in recent years. [0003] In the past ten years, concrete ribbed hollow floors have been widely used in construction projects in my country. The ribbed hollow floor refers to 1. The one-way or two-way type with rib spacing <= 1.5m is called the dense ribbed hollow floor; 2. It is suitable for public buildings with medium or large spans; 3. For ordinar...
