Assemblied polyvinyl chloride building engineering shuttering

Abstract

The present invention relates to a kind of combined polyvinyl chloride building engineering form. It includes hollow perforated board, special-shaped outside corner, special-shaped square pien, square wood, beam side and form closing cover basic structure unit made of polyvinyl chloride material. The above-mentioned basic structure unit can be formed into the engineering form meeting the external form of said designed building component.

Description

technical field [0001] The invention belongs to tooling for building concrete engineering construction, in particular to a combined polyvinyl chloride building engineering formwork. Background technique [0002] With the increasing development and technological progress of the construction industry, it also provides a broad development prospect for the construction formwork industry. At present, the formwork used for concrete pouring such as beams, columns and roof slabs in construction projects is divided into materials, mainly wood or bamboo formwork and steel formwork. Although these formworks have played an important role in the construction of construction projects, with the rapid development of economic construction and the continuous advancement of science and technology, the formwork of the prior art is difficult to meet the needs of building an economical economy. Long service life, but high cost, heavy weight, inconvenient construction and transportation, especial...

AI Technical Summary

Problems solved by technology

Although these formworks have played an important role in the construction of construction projects, with the rapid development of economic construction and the continuous advancement of science and technology, the formwork of the prior art is difficult to meet the needs of building an economical economy. Long service life, but high cost, heavy weight, inconvenient construction and transportation, especially in underwater construction, the corrosion is more serious; and because the steel formwork has a good affinity with cement concrete, it is not easy to demould during use, and the work surface after demoulding Uneven, and the steel formwork sticks to dust and is not easy to clean

Although wood and bamboo formwork is light in weight and easy to construct and transport, it has low strength and is easy to corrode when absorbing water.

During operation, the joint corner of the formwork is easy to leak grout, which affects the pouring quality of the building components; it is easy to be damaged during assembly and disassembly, and becomes garbage or burned materials after use, which is a high-consumption and low-efficiency product

To sum up, the traditional formwork has the disadvantages of high labor costs, easy deviation of geometric dimensions, and complicated formwork support.
