Stepping teeth type self-staggered internal corner template

Abstract

The invention discloses a step joint type self-staggered joint internal corner template, belongs to a building template, and aims to overcome the defects of slag inclusion and necking caused by high probability of mud leakage at a joint of an existing press board. A right-angle complete plate including two right-angle edges is integrally formed by plastic; a joint of a step is arranged on the inner sides of the two right-angle edges respectively; the joint of the step indicates a step form which is formed by a staggered joint lapping edge arranged within the thickness range of the right-angle edges and a staggered joint step higher than the staggered gap lapping edge; the staggered gap steps on the two right-angle edges are connected to be right-angled and are positioned on the inner sides of the included angle of the right-angle complete plate; the thickness of the staggered joint lapping edge and the height of the staggered joint step are 1 / 2 the plate thickness of the right-angle edges respectively; the thickness of the right-angle edges is equal to the plate thickness of the template. During formwork support, the internal corner template is placed at an internal corner of to-be-cast concrete and is lapped and coupled with the template on the plane of the to-be-cast concrete through the joint structure, the formwork supporting efficiency is high, mud leakage does not occur at the corner of the cast concrete, and the defects of slag inclusion and necking are avoided.

Description

technical field [0001] The invention belongs to building templates, in particular to a stepping tooth-shaped self-staggered inner corner template. Background technique [0002] Existing formworks 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 support efficiency. The joints (especially at the corners where the concrete is poured and tamped) are prone to slurry leakage, resulting in slag inclusions and necking defects. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defects that the existing machine-made boards are prone to slurry leakage at the joints, resulting in slag inclusions and necking, and to provide a step-tooth-type self-staggered joint inner corner formwo...
