Combined hollow box body used for cast-in-place energy-saving hollow floor system

Abstract

The invention relates to a combined hollow box body used for a cast-in-place energy-saving hollow floor system, which comprises a bottom surface, an arc surface, a hole wall, a side surface and a top surface, wherein a concave closed hole is remained in the side surface and got through before casting to enable a connecting short pipe to pass through to form a mutually connected through heat energy air supplying channel, a groove for laying a heating pipe is remained on the top surface, and the groove and the heat energy air supplying channel form a floor system energy supplying system; the bottom surface and the side surface of the box body form the arc surface, the arc length of the arc surface is more than 70mm, the length of the arc radius is more than 45mm, and the arc surface is used for preventing a jointing surface of the box body and a rib beam from cracking and the box body from dropping under the conditions of earthquake and the like; and the upper end of the hole wall and the top surface form a casting hole, concrete is poured in the casting hole to be compounded with an iron wire remained on the bottom surface during the cast-in-place, thus the upper wing edge of the floor system can be connected with the bottom surface of the box body, and the stress structure of the floor system is improved. The floor system adopting the hollow box body has the advantages of light weight, large hardness, reasonable structure, crack control and earthquake resistance; and the problem of heating can be solved by adopting a manner of transmitting the heat energy by the box body.

Description

technical field [0001] The invention relates to a construction equipment, in particular to a combined hollow box used for a cast-in-place energy-saving hollow floor. Background technique [0002] Most of the conventional large-span building structure systems use cast-in-place hollow floors, and hollow tubes or hollow boxes are used to solve the technical problem of non-extraction holes. However, the hollow tubes or hollow boxes are permanently buried in the floor, which can only It plays the role of non-centering hole forming. Although the foundation load of the floor is large and the shockproof performance is good, the construction cost is high. In addition, in order to achieve the purpose of centralized geothermal heating, after the pouring of the floor is completed, the geothermal heating device must be installed twice on the building, which increases the development and construction costs of the building, and at the same time fails to achieve the energy-saving and land-s...

Problems solved by technology

[0004] However, the hollow floor built with such a thin-walled box still needs to install the geothermal heating device twice after the floor is poured, which cannot satisfy the simultaneous construction of the floor and building geothermal heating devices to achieve low-carbon energy saving socioeconomic effects of
