Stepping teeth type self-staggered joint formwork system

Abstract

The invention discloses a step combed joint type self-staggered-joint formwork system and belongs to building formworks. Existing machine-made plates cannot be recycled after being damaged, slurry is prone to leakage at joints, so that dreg inclusion and necking are caused, dislocation is like to happen at the two ends, and then a formwork system is deformed. The step combed joint type self-staggered-joint formwork system is composed of planar formworks, external corner formworks, internal corner formworks and base corner formworks, wherein the planar formworks, the external corner formworks, the internal corner formworks and the base corner formworks are made of plastic and are in layered layout, the formworks on the same layer have the identical height, the formworks which are adjacent and connected vertically belong to the same type, the adjacent formworks are in combed lap joint with each other, each base corner formworks is in combed lap joint with the corresponding formwork located above the base corner formwork through a vertical landing edge, and the lap joint portions are fastened through fasteners. After the formworks are used, all the formworks can be recycled; after the recycled formworks are machined again, the formworks can be used again; connection between every two adjacent formworks is firmer through the combed joints, the defects of dreg inclusion, necking, slurry leakage and the like are avoided, deformation of the formwork system is avoided, and mutual interference of bolts at wall corners, wall columns and vertically and horizontally intersections of walls is avoided through eccentric staggering.

Description

technical field [0001] The invention belongs to building templates, in particular to a stepping-toothed type self-staggered seam template system. Background technique [0002] The existing formwork widely used in construction engineering formwork systems are mostly "machine-made boards" (collectively referred to as machine-made wood plywood and bamboo plywood), which cannot be recycled after damage, resulting in serious waste of materials and low formwork efficiency. It is easy to leak grout at the joints of the formwork (especially at the corners where the concrete is poured and tamped), resulting in slag inclusions and necking defects. When setting up the formwork, although the machine-made slab can be fixed by nails, due to the lack of support at both ends of the machine-made slab, misalignment can easily cause deformation of the formwork support system and reduce the accuracy of pouring concrete. [0003] The existing screw rods for supporting the formwork generally tig...

Problems solved by technology

[0004] The technical problem to be solved and the technical task proposed by the present invention are to overcome the fact that the existing machine-made boards cannot be recycled after being damaged, the waste of materials is serious, the joints are easy to leak, resulting in slag inclusions, necking, lack of support at both ends of the machine-made boards, It is easy to produce misalignment, resulting in deformation defects of the formwork system. A stepping tooth type self-staggered joint formwork system is provided, and on this basis, it overcomes the defects of interference and fight when the screws for the formwork are crossed vertically and horizontally, and single function.
