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

Abstract

The invention relates to a combined hollow box body for a cast-in-place energy-saving hollow floor, which consists of a bottom surface, an arc-shaped surface, a hole wall, a side surface and a top surface, wherein inwards recessed closed holes are reserved on the side surface and can be penetrated before casting for passing a connecting short pipe to form mutually connected and penetrated heat energy air supply passages, grooves for paving heating pipes are reserved on the top surface, the side surface and the top surface form a floor energy supplying system, an arc-shaped surface is formed between the bottom surface and the side surface of the box body, the length of the arc shape of the arc-shaped surface is greater than 70mm, the length of the radius of the arc shape is greater than 45mm, the arc-shaped surface is used for preventing the cracking of the combined parts of the box body and rib beams and the falling of the box body under the conditions of earthquakes and the like, the upper end of the hole wall and the top surface form a casting hole, concrete is filled in the casting hole during cast-in-plate operation to be compounded with reserved iron wires of the bottom surface, an upper wing edge of the floor and the bottom surface of the box body can be tightly connected, and the floor stress structure is improved. The floor adopting the hollow box body has light weight, high hardness and reasonable structure, prevents the cracking, resists the shock and can simultaneously solve the heating problem by using the box body to transmit the heat energy.

Description

Technical field [0001] The invention relates to a construction equipment, in particular to a combined hollow box for cast-in-situ energy-saving hollow floor. Background technique [0002] Conventional large-span building structure systems mostly use cast-in-place hollow floors, and hollow pipes or hollow boxes are used to solve the technical problems of non-core drilling. However, the hollow pipes or hollow boxes are permanently embedded in the floor. It plays the role of non-cored hole formation. Although the foundation load of the floor is large and the seismic performance is good, the construction cost is high. In addition, in order to achieve the purpose of centralized geothermal heating, after the completion of the pouring of the floor, the building has to be re-installed with geothermal heating devices, which increases the development and construction cost of the building, and at the same time it does not meet the energy-saving and land-saving type advocated by the country....

Problems solved by technology

[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-saving model advocated by the state. and requirements for low-carbon and environmentally friendly building structures

[0003] In the utility model patent of his early patent ZL02282007, the applicant disclosed a thin-walled box for fasting floors with thin-walled boxes. Using this component successfully solved the technical problem of non-core-pulling holes for cast-in-place fasted floors. At the same time, it solves the defect of unbalanced force transmission in the vertical and horizontal directions of the existing floor, which can greatly reduce the weight of the foundation load, enhance the earthquake resistance, reduce the cost, and realize the arbitrary partition of the building space. It is widely used in the construction industry. 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
