Description

Reentrant corner connecting piece suitable for small wall buttress is consolidated

Technical Field

The utility model belongs to the field of constructional engineering, relates to a connecting piece, and particularly relates to an internal corner connecting piece suitable for reinforcing a small wall buttress.

Background

When a building wall is poured, the templates, the battens and the keels are indispensable temporary supporting structures, the templates are surrounded into a structure for pouring the wall, the battens are structures for supporting the templates, and the keels are structures for reinforcing the templates so as to prevent the templates from deforming under stress and ensure the pouring quality of the wall.

The parts protruding outwards at the two ends of the wall body are called as wall piles, and the included angle between the wall piles and the inner side of the wall body is called as an internal corner. At present, when a template is reinforced, a straight structure of a wall body and a wall crib is only reinforced, the end part of a keel at the wall body or the wall crib extends out to cover the end surface of a batten at an internal corner, the keel at the wall crib or the wall body abuts against the extending part, and the batten is easy to move because the batten is not completely clamped; meanwhile, because the wall body expands in the hardening process, if the internal corners are not reliably reinforced, the corners of the internal corners deform, so that the pouring quality is affected.

In addition, for the small wall piles with narrow widths, during reinforcement, constructors need to specially select proper sizes from main keels with various specifications, so that the main keels can just extend out of one part of the end part of the wall pile to be assembled with the locking notch cross arm, the extending parts are too short, the wall pile is inconvenient to assemble with the locking notch cross arm, and the extending parts are too long, and the wall pile is not beneficial to integral stress and construction.
