Multi-supporting post anti-floating box body for cast-in-place concrete hollow floor slab

Abstract

The invention relates to a multi-supporting post anti-floating box body for a cast-in-place concrete hollow floor slab. The box body comprises a box body A; the box body A is of a cubic groove type structure; at least two supporting posts which are perpendicular to the bottom surface are uniformly distributed in the box body A; *-shaped reinforcing ribs with exhaust holes are arranged on the bottom surface of the box body A; exhaust holes are uniformly distributed among the reinforcing ribs on the bottom surface of the box body A; vertical reinforcing ribs with exhaust holes are arranged on each of the four side surfaces of the box body A; the upper ends of the side surfaces of the box body A are provided with circumferential fixed edges; and supporting leg mounting holes are vertically formed in the four vertex angles of the box body A. The multi-supporting post anti-floating box body for the cast-in-place concrete hollow floor slab is simple and reasonable in structure; the thicknessof the box body can be combined randomly; meanwhile, the height of the box body from the bottom plate can be adjusted randomly by inserting supporting legs; the labor intensity is low; the cost is low; the construction progress is fast; and the quality is easy to control.

Description

technical field [0001] The invention relates to a permanent built-in box body construction component used in the on-site construction and pouring of a building cast-in-situ concrete hollow floor slab, in particular to a multi-pillar anti-floating box body of a cast-in-place hollow floor slab. Background technique [0002] With the progress of society and the development of market economy, a large number of new structural products and construction methods emerge, and the diversification of materials is becoming more and more obvious. Among them, a kind of cast-in-place concrete hollow floor in the construction of building structures uses a large number of permanent built-in The box body reduces the overall cost of the building and increases the usable space by reducing the concrete in some beams, columns and slabs, so that the structural force is more reasonable. [0003] At present, more and more new projects in the construction industry tend to be large-space, beamless, and...

Problems solved by technology

[0004] The built-in box of the traditional cast-in-place beamless hollow floor slab needs to be installed in the middle of the reinforced concrete of the hollow slab during construction. Therefore, it is required to arrange, install and fix the box according to the drawing requirements after the bottom reinforcement is laid. At the same time, pads are set on the four feet of each box, and each built-in box is bound to the bottom steel bar with iron wires to prevent the built-in box from floating or horizontal displacement during concrete construction. The body needs to be fixed independently to ensure the distance between each other. Due to the cumbersome work of binding steel bars, high labor intensity, a large number of pads and high cost of binding materials are required, and the quality is difficult to control, which affects the construction progress.
