Reversed cantilever beam structure plastic building formwork

Abstract

The invention provides a plastic building formwork with inverted outrigger structures. The plastic building formwork comprises a single-inverted outrigger formwork, a double-inverted outrigger formwork and a sixfold-inverted outrigger formwork. The single-inverted outrigger formwork is an integrally frame-shaped extrusion-molded integrated member and comprises a front side transverse plate, a middle transverse plate, a left side longitudinal plate, a right side longitudinal plate, a left support leg, a right support leg, three longitudinal rib plates, an arched rib plate, a first skew plate and a second skew plate; the three longitudinal rib plates sequentially include a first longitudinal rib plate, a second longitudinal rib plate and a third longitudinal rib plate from the left to the right; the double-inverted outrigger formwork comprises single-inverted outrigger formworks which are used as basic units, and the single-inverted outrigger formworks repeatedly extend in the left-right direction twice to form the double-inverted outrigger formwork; the sixfold-inverted outrigger formwork comprises single-inverted outrigger formworks which are used as basic units, and the single-inverted outrigger formworks repeatedly extend in the left-right direction by five times to form the sixfold-inverted outrigger formwork. The plastic building formwork has the advantages that the plastic building formwork is used with matched buckle connectors, the formworks can be closely and firmly spliced with one another without mud leakage and are high in compressive capacity, time and labor can be saved when the plastic building formwork is mounted and detached, working hours and the cost can be saved.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201210214377.8, the application date is June 26, 2012, and the invention name is "plastic building formwork and buckle connector". technical field [0002] The invention relates to a building construction tool, in particular to a building formwork. Background technique [0003] In modern engineering buildings, when pouring concrete on site to construct beams, columns, facade walls, floors and other units, a large number of building formwork must be used. Traditional building formwork generally uses wooden formwork or steel formwork. The wooden formwork is easy to rot, and the number of repeated use is small, and it is easy to bond with the concrete during use, and it is difficult to demould, which brings inconvenience to the construction, and the large-scale use of wood will cause waste of forest resources; the steel formwork is heavy and expensive , constructi...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, especially the insufficient compressive capacity of the plastic formwork, the inconvenient connection and assembly of the formwork, and the gaps in the formwork connection parts, and provide a new structure of plastic building formwork with reverse cantilever beam structure and its The matching buckle connector has strong compressive capacity, the formwork connection assembly and disassembly are quick and convenient, and the formwork connection is tight without leakage
