Template structure for manufacturing bare concrete wall arc-shaped inside corner

Abstract

The invention discloses a template structure for manufacturing a bare concrete wall arc-shaped inside corner. The template structure comprises templates, wherein a fan-shaped template is arranged between the end faces of the mutually perpendicular templates; the inner end face of the fan-shaped template is an arc-shaped surface; two connecting plates in contact with the mutually perpendicular templates respectively are arranged at the outer end of the fan-shaped template; tips of two nails or tapping screws penetrate through the connecting plates at the outer end of the fan-shaped template respectively to be buried in the mutually perpendicular templates; elastic cushions are arranged between the two side surfaces of the fan-shaped template and the end faces of the mutually perpendicular templates. The template structure has the following remarkable advantages: the template structure can be manufactured into an arc shape and has bright and clean surface quality.

Description

Technical field: [0001] The invention relates to a building formwork, in particular to a formwork structure for making curved inner corners of fair-faced concrete walls. Background technique: [0002] Cast-in-place concrete structure walls are often constructed with wooden formwork or plastic formwork, and steel pipe fasteners or square wood fasteners are often used to fix between walls or columns. However, due to the narrow corners, the operation is difficult and the efficiency is low. There is a risk of sliding failure of the parts, which will lead to the deformation of the joints of the internal corner formwork, and the internal corners are not square, especially for fair-faced concrete, which is prone to grout leakage and mold swelling. Manual trimming of the internal corners is required, which is labor-intensive and time-consuming, and affects the surface quality; in addition , in order to meet the needs of aesthetics, some designs require the inner corner to be in the ...

[0002] Cast-in-place concrete structure walls are often constructed with wooden formwork or plastic formwork, and steel pipe fasteners or square wooden fasteners are often used to fix between walls or columns. However, due to the narrow internal corners, the operation is difficult and the efficiency is low. There is a risk of sliding failure of parts, resulting in joint deformation of the internal corner formwork, and the internal corner is not square, especially for fair-faced concrete, which is prone to grout leakage and mold expansion. Manual trimming of the internal corner is required, which is labor-intensive and time-consuming, and affects the surface quality; , for the sake of aesthetics, some designs require the inner corner to be in the shape of a circular arc, and a template for making the inner corner of the arc is required
