Hollow body, hollow floor and manufacturing method of hollow floor

Abstract

The invention provides a hollow body. The hollow body is characterized in that a lower cover detachably covers the lower end of an annular lateral wall, an upper cover covers the upper end of the annular lateral wall, and an inner cavity is formed among the lower cover, the annular lateral wall and the upper cover. Preferably, the upper cover detachably covers the upper end of the annular lateral wall. The annular lateral wall is formed by folding a foldable part in a surrounding manner. A through hole is formed in the annular lateral wall. A plurality of vertical folding lines are vertically arranged on the annular lateral wall at intervals. The invention further provides a related hollow floor and a manufacturing and construction method of the hollow floor. The hollow body has the advantages that the hollow body is ingenious in design, simple in structure, convenient to store and transport, capable of increasing prefabricating rate, time saving, labor saving, capable of lowering cost and shortening construction period, safe, economical, environmental friendly, and suitable for large-scale popularization and application; the hollow body does not float in concrete which is not cured, the hollow body can be removed after being combined with a cured concrete base plate, water accumulation in the cavity is avoided, the related hollow floor can be prefabricated, and in-situ reinforcing steel bar laying and hollow floor pouring can be reduced.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to the technical field of floor components, and specifically refers to a hollow body, a hollow floor and a method for manufacturing a hollow floor. Background technique [0002] Nowadays, in the field of concrete structural parts, hollow-core slab is a relatively advanced component at present. However, due to the variety and complexity of hollow bodies used for hollow slabs and their different functions, hollow slabs are still mostly constructed with cast-in-place solutions in the construction industry, and an industrialized production system has not yet been formed to enable them to be mass-produced And cater to the development needs of real estate industrialization. Hollow body is a lightweight substitute for concrete, generally divided into filling body and cavity body. The hollow body is generally a spherical or rectangular model. The construction scheme of t...

AI Technical Summary

Problems solved by technology

In the existing technology, the solution of adding permanent steel consumables is not environmentally friendly and economical, and the other solution requires too much production time and space, which hinders the development of industrial production of hollow floor slab assembly lines

[0012] 3) Another shortcoming of the existing hollow body is that it cannot be removed after being combined with the solidified concrete floor

This type of restoration is difficult to guarantee the quality of restoration in difficult construction sites

Therefore, it often leads to problems of unevenness and leakage of the floor.

[0013] 4) The existing cavity body also has the defect of water accumulation in the cavity due to the design defect of the vent hole at the top

Smaller defects can lead to floor leakage, and larger ones can lead to structural cracking and spalling of concrete caused by freeze-thawaction, resulting in loss of life and property

[0014] 5) The existing hollow-core floor prefabrication scheme can only be semi-prefabricated

On-site pouring requires a lot of manpower and material resources, and will inevitably produce a lot of construction waste, causing environmental pollution
