Embodiment Construction

[0041] Examples see Figure 1 to Figure 5 As shown, a PCM cast-in-place reinforced concrete large-scale sandwich floor slab has concealed beams 8 at intervals, and is composed of a mandrel 4, upper steel bars 1, lower steel bars 2 and outsourcing concrete 3, and the mandrel 4 is a solid The polyphenylene block has an upper steel bar 1 bound on its top surface and a lower steel bar 2 bound on its bottom surface, and is wrapped by outsourcing concrete 3 to form a whole. The core mold 4 is a solid bucket-shaped body surrounded by four sides 4.1, four folded surfaces 4.3 folded into the body, a bottom surface 4.2 and a top surface 4.4, wherein each side 4.1 is connected with the folded surface 4.3. The bottom surface 4.2 is connected, and there is at least one inspection hole 5 . The diameter of the inspection hole 5 is 100mm-150mm. The angle α between the folding surface 4.3 and the bottom surface 4.2 is 30°-60°. The plane size of the mandrel is 1000mm×1000mm.

Abstract

The invention relates to a phase change material (PCM) cast-in-place reinforced concrete large-size sandwiched floor and a construction method thereof. Concealed beams are arranged in the sandwiched floor at intervals; the sandwiched floor consists of a core die, upper steel bars, lower steel bars and outer-packed concrete; and the core die is a solid polystyrene block, the upper steel bars are bound on the top of the core die, the lower steel bars are bound on the bottom surface of the die core, and the steel bars and the core die are wrapped into a whole through the outer-packed concrete. An inner die floats upwards in the pouring process, and the lower steel bars and the upper steel bars are bound with the keel of a bottom template through anti-floating steel wires. The sandwiched floor has the advantages of light dead weight, good anti-seismic and sound insulation effects, no limit on embedded pipelines in the construction process and the like. The sandwiched floor can be widely applied to multi-layer and high-layer buildings with larger spans and loads and thicker floors.

Description

technical field [0001] The invention relates to a floor slab and its construction method, in particular to a sandwich floor slab and its construction method. Background technique [0002] PCM cast-in-place hollow-core floor structure technology is the third-generation hollow-core slab structure technology in China. In order to increase the net height of buildings and reduce construction costs, cast-in-place reinforced concrete sandwich floor slabs are used in large-span garages or high-rise buildings. Compared with the floor slab, it has the main advantages of reducing the weight of the structure, benefiting from earthquake resistance, improving headroom, and good sound insulation. The existing mandrel is the inner mold of a rectangular hollow cement box. There is a problem that the hollow box cannot be slotted and passed through the pipe, the pipeline can only be arranged along the beam, and the outsourcing concrete is not easy to flow to the bottom of the slab. Difficult...
