Description

Technical Field

[0001] The invention relates to the technical field of cast-in-place concrete, in particular to a self-positioning and rapid assembly forming box for cast-in-place hollow floor slabs. Background Art

[0002] The cast-in-place hollow slab structure has the characteristics of large span, light weight, good performance, low cost and convenient construction. It is particularly suitable for large-span and high-rise buildings.

[0003] At present, more and more new projects in the construction industry tend to be large-space, beamless and few-column structures, that is, cast-in-place beamless hollow slab structural systems. The system is characterized by a gap grid formed by multiple boxes evenly distributed in water and arranged with gaps in the cast-in-place slab. The hidden beam system formed after the concrete is poured on site bears its external load, avoiding the effect of the original main and secondary beams being exposed and occupying space under the slab, which saves raw materials and increases the usable space, speeds up the construction period and reduces costs.

[0004] The traditional cast-in-place beamless hollow slab has a complex manufacturing process and low processing efficiency. The built-in box is not easy to transport and install during use. Moreover, during construction, the built-in box and the bottom need pads, which affects the flow of the lower part during the concrete pouring process, resulting in incomplete vibration of the bottom concrete. The box also needs to be treated with anti-floating treatment, and the width of the rib beams between the boxes cannot be controlled. Summary of the invention

[0005] The purpose of the present invention is to solve the deficiencies of the prior art and provide

[0006] In order to achieve the above objectives, the following technical solutions are provided:

[0007] A self-positioning and rapid assembly forming box for cast-in-place hollow slabs comprises a cover plate, a side plate and a support, wherein the cover plate comprises limiting grooves on four sides, evenly distributed exhaust holes and circular holes at four top corners, wherein adjusting legs are installed in the circular holes, and the length of the adjusting legs is selected according to the distance between the box body and the template, wherein the side plates are inserted in the limiting grooves of the cover plate to form a rectangular parallelepiped, wherein the side plates have cover plates above and below, wherein a fixed support seat is injection-molded on the cover plate, and the support is inserted in the fixed support seat to support the upper and lower cover plates.

[0008] Preferably, it also includes a rectangular horizontal connecting plate of the box body, which has connecting holes at the four vertices and a through hole in the center. The adjusting legs pass through the connecting holes of the horizontal connecting plate of the box body and are inserted into the circular holes of the cover plate, thereby limiting and horizontally supporting four adjacent boxes.

[0009] Preferably, the cover plate has a flat bottom, and four corners are injection-molded with steel bar mounting seats, and the steel bar mounting seats have concave and convex surfaces so as to be installed on a steel bar frame.

[0010] Preferably, the cover plate has a trapezoidal bottom, the fixed support seat is located at the vertex inside the cover plate, and reinforcing ribs are provided inside the trapezoidal bottom.

[0011] Preferably, the fixed support seat is located at the center of the cover plate.

[0012] Preferably, the fixed support seat is located at a support point inside the cover plate, and reinforcing ribs are provided inside the cover plate.

[0013] Preferably, a circular groove is injection-molded at the center of the cover plate, the tube support is inserted into the circular groove, and the upper and lower cover plates are reinforced and supported by the tube support.

[0014] The side panels are ribbed steel plate meshes, which are connected to the upper and lower cover plate nails, or the side panels are high-strength plates, which are connected to the upper and lower cover plate nails.

[0015] Preferably, the cover plate has a trapezoidal bottom and / or a flat bottom, that is, the upper and lower cover plates may be the same or different.

[0016] The beneficial effects of the present invention are:

[0017] 1. This application adopts a structure in which the side panels are inserted into the upper and lower cover panels, which can achieve the effect of quick disassembly, arbitrary assembly, and arbitrary adjustment of the height of the box.

[0018] 2. Since the present application adopts a detachable assembly form and the upper and lower cover plates have the same structure, the present application reduces the number of molds and reduces costs.

[0019] 3. This application adopts a round hole and an adjustable leg structure, eliminating the traditional pad structure, the leg length is adjustable, the concrete at the bottom of the box has better fluidity, is easy to install, has a fast construction period, and uses less materials.

[0020] 4. The pipe support structure supports the upper and lower cover plates and is also convenient for exhaust, observation and vibration.

[0021] 5. After pouring is completed, the use of a trapezoidal bottom cover box and an I-shaped force-bearing structure between the box bodies can make the rib beams formed between the box bodies bear better force.

[0022] 6. The exhaust holes distributed on the upper and lower cover plates can reduce the buoyancy caused by concrete on the box body; the side panels are made of reinforced steel mesh, which can also effectively reduce the buoyancy caused by concrete pouring. At the same time, the structure of upper and lower cover plates combined with reinforced steel mesh is stronger, less prone to deformation, less likely to leak slurry, and has better construction operability than the traditional structure with steel mesh on all four sides.
