Connecting piece of plastic template

Abstract

The invention discloses a connecting piece of a plastic template. The connecting piece comprises a plate body, wherein the plate body is provided with an L-shaped corner, the side edge of the plate body is provided with two pin shafts, a pin hole is formed between the two pin shafts, the plate body is further provided with an L-shaped rabbet, the opening of the rabbet is outward, the cross section of the plate body is step-shaped, the length of each pin shaft of the plate body is consistent with that of the template, the diameter of each pin shaft is consistent with the inner diameter of each pin hole of the template, and the center distance of the pin shafts is consistent with the hole distance of the pin holes of the template. The connecting piece disclosed by the invention has the beneficial effects that application and popularization of a sizing plastic template are realized, the connecting piece is matched with an existing domestic plastic template system for use, can meet effective connections among various concrete component templates required by a design, is strong in operability and can be easily mastered and applied by workers.

Description

technical field [0001] The invention relates to a connector for a plastic formwork, which belongs to the field of construction tools. Background technique [0002] At present, more than 95% of the known building templates for the construction of cast-in-place concrete structures still use building wood plywood, laminated panels, multi-layer panels, double-sided adhesives, double-sided laminated panels, combined Shaped steel formwork or large integrally installed steel formwork. Wooden formwork is complex in manufacturing process, poor in construction accuracy, labor-intensive in installation and dismantling, high in labor intensity, less in turnover times of formwork, and the noise and dust of on-site processing and production pollute the environment seriously, which does not meet the requirements of green construction; steel formwork is heavy and expensive High, large steel formwork is not conducive to transportation and on-site stacking. As for the use and promotion of p...

Wooden formwork is complex in manufacturing process, poor in construction accuracy, labor-intensive in installation and dismantling, high in labor intensity, less in turnover times of formwork, and the noise and dust of on-site processing and production pollute the environment seriously, which does not meet the requirements of green construction; steel formwork is heavy and expensive High, large steel formwork is not conducive to transportation and on-site stacking

As for the use and promotion of plastic formwork, after repeated practice, analysis and research, the current production and application status of this product in China is: it is always in the initial stage of trial production and trial application. The main reason is that the domestic production of plastic formwork is limited. The type, model and size cannot meet the formwork installation requirements of engineering design. With domestically produced plastic formwork, the geometric figures of all components cannot be spelled out, especially when the floor height of the house, the size of the bay, or concrete components such as beams, slabs, and columns When the cross-sectional size does not completely match the normal design modulus, it is impossible to solve the problem of tight connection and effective reinforcement of the formwork between components, especially between special-shaped components. Therefore, in the promotion and application of this product, due to low work efficiency or affecting individual benefits, there will be great resistance or resentment among employees
