Description

A hollow plate light tube anti-floating structure

technical field

The utility model relates to a building construction structure, in particular to an anti-floating structure for a hollow plate light pipe.

Background technique

In the field of construction, with the increasing number of long-span concrete structures, more and more floor slabs adopt the technology of cast-in-place concrete hollow slabs. When constructing cast-in-place concrete hollow slabs, it is necessary to carry out anti-floating treatment for lightweight pipes. At present, the anti-floating of hollow plate lightweight pipes is generally fixed by lead wires. The specific method of anti-floating control points is usually: after the light pipe and the upper and lower steel bars of the hollow slab are installed, at the position corresponding to the rib beam of the hollow slab, one end of the lead wire is passed downward through the pre-punched hole on the formwork , after being tied firmly with the support system of the formwork, the end of the lead wire is passed back through the hole upwards, and the two ends of the lead wire are tightened and fixed at the anti-floating control point. With this structure, the construction is inconvenient, time-consuming and labor-intensive, the efficiency is low, and the anti-floating effect is general.

Utility model content

The utility model provides an anti-floating structure of a hollow plate light pipe with convenient construction and good anti-floating effect in order to solve the technical problems existing in the known technology.

The technical solution adopted by the utility model to solve the technical problems existing in the known technology is: a hollow slab lightweight pipe anti-floating structure, including formwork support system, hollow slab formwork, hollow slab lower steel bars, The lightweight tube and the steel bars on the upper layer of the hollow slab, the two ends of the light tube are respectively provided with fixed grids, and the fixed grids are fixed on the lower steel bars of the hollow slab with binding wires, at multiple anti-floating points The lower steel bars of the hollow slab, the fixed grid and the hollow slab formwork are bound on the formwork support system with lead wires; connect.

At least one anti-floating point is provided within a range corresponding to each square meter of the hollow plate, and one lead wire is provided at each anti-floating point.

All the anti-floating points are arranged in a quincunx shape.

The utility model has the advantages and positive effects: the fixed grid of the hollow tube, the lower steel bar of the hollow slab and the hollow slab formwork are bound on the formwork support system with lead wires, which saves materials, is convenient for construction, and can improve construction efficiency; the hollow slab The lower steel bars and the upper steel bars of the hollow slab are connected by drag hooks, which can improve the anti-floating effect, and can accurately control the dimensional tolerance and shape tolerance of the plate thickness. In summary, the utility model is easy to construct and can guarantee the construction quality.

Detailed ways

In order to further understand the invention content, characteristics and effects of the present utility model, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Please refer to Fig. 1, a hollow slab lightweight tube anti-floating structure, including a formwork support system, a hollow slab template 6, a hollow slab lower reinforcement 9, a lightweight tube 8 and a hollow slab upper reinforcement 10 arranged sequentially from bottom to top. The two ends of the light pipe 8 are respectively provided with fixed grids 1, and the fixed grids 1 are fixed on the lower steel bars 9 of the hollow slab by using binding wires. 9. The fixed grid 1 and the hollow slab formwork 6 are bound on the formwork support system with lead wires 3; the lower steel bars 9 of the hollow slab and the upper steel bars 10 of the hollow slab are drawn hooks at multiple points 2 connections.

In this embodiment, at least one anti-floating point is provided within a range corresponding to each square meter of the hollow plate, and one lead wire 3 is provided at each anti-floating point. The setting of the anti-floating point is not limited by the position of the rib beam of the hollow slab, and the construction is more convenient. Usually, all the anti-floating points are arranged in a quincunx shape.

In the present embodiment, the same as the prior art, the above-mentioned formwork support system includes a fixed support steel pipe 4 and a wooden square keel 5 supported by it, and the hollow plate formwork 6 is supported by the wooden square keel 5. Between the hollow plate formwork 6 and the hollow Pads 7 are arranged between the steel bars 9 of the lower slab.

Although the preferred embodiment of the utility model has been described above in conjunction with the accompanying drawings, the utility model is not limited to the above-mentioned specific implementation, and the above-mentioned specific implementation is only illustrative and not restrictive. Under the enlightenment of the utility model, those skilled in the art can also make many forms without departing from the purpose of the utility model and the protection scope of the claims, and these all belong to the protection scope of the utility model.
