Concrete beam formwork support

Abstract

The invention provides a concrete beam formwork support, relates to the engineering of concrete beam formworks, and adopts a cantilever type support to solve the problems of complex bolt-through beams and components, difficult size adjustment and working hour waste in the prior beam formwork support. The support consists of two supporting arms, a pull rod, a wedged plate and a pressure lever, wherein the supporting arms comprise two rod welding plates, the pressure lever is supported on the lower ends of the supporting arms, the pull rod pulls the two supporting arms at a lower rim position of a beam bottom formwork, and the wedged plate is used for connecting and fastening the pull rod and the supporting arms. A force couple formed by inner forces of the pull rod and the pressure lever balances bending moment of the supporting arms to simplify supporting components, therefore, the support achieves the assumption of adjusting working width and height of the beam formwork support flexibly and conveniently according to different sizes of concrete beams, and can be applied to formwork engineering of non-as-cast finish and as-cast finish concrete beams. Because of simplified structure of the support and wedge connection, the support has the advantages that the support expands application range, improves turnover ratio and working quality, and saves materials and working hours.

Description

technical field [0001] The invention relates to a concrete beam formwork support for construction engineering. Background technique [0002] In the construction of the beam-slab structure of the floor, there are many forms of formwork support commonly used for concrete beams, which are roughly divided into two categories, one is the pull bolt type, and the other is the bracket type. [0003] The beam form support of the anti-tension bolt type basically does not form a turnover tool, the component turnover rate is low, and the work hours are consumed; because the upper anti-tension bolt needs to pass through the concrete of the beam body, the integrity of the beam surface is damaged. In today's In the building structure that adopts fair-faced concrete more and more widely, the beam formwork support technology of the tension bolt type has been replaced by the support type beam formwork support technology. [0004] There are many styles and dimensional adjustment methods of br...

Problems solved by technology

[0005] In order to solve the problems of the bolts passing through the beam and the waste of man-hours supported by the bolt type beam formwork, and also to solve the problems of low size adjustment efficiency of the bracket type beam formwork support and the lack of fastening of the beam formwork support, the invention provides a new concrete beam Formwork support can simplify support components, improve the efficiency of beam formwork support, the efficiency of formwork support and the quality of concrete components, and reduce costs
