A small assembly type auxiliary corner cast-in-situ concrete construction column tool

Abstract

This utility model relates to the field of auxiliary tools for cast-in-place concrete structural columns, specifically a small prefabricated auxiliary tool for corner cast-in-place concrete structural columns. It includes an L-shaped front plate, an L-shaped rear plate, an arch-shaped clamp, a C-shaped plate, and a square plate. The L-shaped front plate comprises a first L-shaped front plate and a second L-shaped front plate arranged vertically. The L-shaped rear plate comprises a first L-shaped rear plate and a second L-shaped rear plate arranged vertically. The C-shaped plate comprises a perforated concave plate and a perforated convex plate. The upper and lower inner sides of the perforated concave plate have slots, and the upper and lower outer sides of the perforated convex plate have protrusions that fit the slots. Compared to existing technologies, this patent, by setting a C-shaped plate composed of a perforated concave plate and a perforated convex plate, creates a dimensional difference with the bottom support, allowing for precise one-time molding of a regular toothed joint structure during concrete pouring. This solves the technical problem that the toothed joint dimensions rely entirely on manual control, resulting in inconsistent quality and affecting the connection between the structural column and the wall.
