Technical Field

The invention belongs to the field of engineering construction, and mainly aims at cast-in-place concrete structure drop plate formwork hanging construction.

Background

At present, in some structures encountered in civil residential building construction, a toilet floor slab is a descending slab relative to a peripheral structural slab, the difference of the top standard height is 50mm, and a hanging die is required to be arranged for the descending slab of the toilet in actual construction. The conventional construction method is that the suspended formwork is formed by splicing wooden formworks or battens, the lower part of the suspended formwork is supported by a steel bar split heads, and the two sides of the suspended formwork are clamped by steel bars to ensure that the suspended formwork does not move off-normal in the concrete pouring process, and the method has the following defects: 1. the wood template has insufficient splicing rigidity, the template is easy to deform or shift during concrete pouring, and the geometric dimension of a concrete member cannot be ensured; 2. the wood template has small dead weight and is infirm in local reinforcement, and concrete is easy to float upwards during pouring, so that the elevation of the edge of the falling plate is higher, and secondary chiseling treatment is needed in the later period; 3. the wood formwork is adopted, the whole body cannot be removed during removal, the wood formwork needs to be removed in a slicing mode, concrete slurry is adhered to the bottom of the wood formwork, and a crowbar is needed to be matched during removal, so that the damage to the edges and corners of the formed concrete is serious.

Disclosure of Invention

In order to solve the technical problems, the technical scheme provided by the invention is as follows,

the utility model provides a cast-in-place concrete floor structure falls board construction mould which characterized in that: the steel bar reinforced formwork structure comprises a rectangular main framework structure formed by angle steel, wherein a formwork lifting positioning reinforcing rib is arranged on the outer side of the main framework structure, a bevel edge opening of the angle steel is welded and sealed by a steel plate 3, a steel bar support is arranged inside the main framework along the side length direction of two sides of the rectangle, and a steel bar protective layer cushion block is further arranged at the bottom of the formwork lifting positioning reinforcing rib.

Further, the specification of the angle steel is L50 multiplied by 32 multiplied by 3.

Further, the thickness of the steel plate is 2 mm.

Further, the reinforcing steel bar support adopts a reinforcing steel bar with the diameter of 16 mm.

Further, the steel plate is 120 degrees with the horizontal plane when covering the angle steel.

The invention has the advantages and beneficial effects that:

1. because the whole steel formwork is adopted, the whole formwork can be used all the time, the turnover frequency of the formwork is increased, the construction can be carried out for 60 times, and the turnover of a common wood formwork is carried out for 8 times.

2. The invention has the advantages of easily obtained materials, simple manufacture and convenient installation and removal, greatly reduces the labor cost and improves the working efficiency.

3. The method uses an integral removing method for removing the hanging mould, thereby effectively ensuring the concrete forming quality.
