Disassembling-free lattice beam mould

Abstract

The invention relates to a non-detachable grid beam mould which uses wing plate to increase the contact area and friction with reinforced concrete. The invention comprises a first hollow post whose bottom horizontally extends a base, at least one wing plate at the outer edge of the first hollow post. The invention uses one hollow post and a horizontal accuracy adjuster to increase the height of grid beam mould and adjust the horizontal accuracy.

Description

technical field [0001] The invention relates to a dismantling-free lattice beam mold used in the construction industry, in particular to a dismantling-free lattice beam mold which is loose-proof and can be changed in height. Background technique [0002] With the progress of the times and product innovation, in high-tech factories, due to the demand for precise manufacturing processes, high-quality products must be manufactured in a clean environment, and there are often steel frames or reinforced concrete (Reinforced Concrete, RC) manufacturing elevated floor design, in addition to the need for air return and the convenience of pipeline configuration, and the more precise the process, the more urgent the demand for earthquake resistance, so the use of RC lattice beams can better meet the requirements for structural strength. [0003] In the early construction of lattice beams, wooden formwork was used to form first, after grouting, demoulding, and then coating epoxy resin, ...

AI Technical Summary

Problems solved by technology

[0003] In the early construction of lattice beams, wooden formwork was used to form first, after grouting, demoulding, and then coating epoxy resin, these methods were time-consuming and the quality of the finish was different; another method was to provide a non-demolition mold that was directly combined with the RC structure. It is characterized by an integrated mold formed by glass fiber molding (Sheet Molding Compound, SMC). It is designed with a rough surface and a smooth inner surface. Although it can save the steps of dismantling the early mold, it is vulnerable to solidified RC. Extruded and deformed, and unable to connect with other molds, it is easy to cause a small number of molds to loosen. An improved method has been disclosed in the patent case of "Removable Lattice Beam Mold" with the announcement number M246392, as shown in Figure 1. It is a round tube mold 100, its round tube part 102 adopts the design of taper taper, and there are a plurality of perforations 104 on its flange edge 110, which can be used for the connection of each mold, but because its round tube mold 100 is smooth On the surface, there are still doubts that a small number of round pipes will loosen because they cannot withstand RC extrusion. In addition, due to the different factory scale and structural stiffness requirements, the height and thickness of the mold will also be different. The general lattice beam mold A raised floor will be set up to meet the demand, so it will not be able to effectively shorten the construction time and the cost of the raised floor
