Pier stud template for road and bridge construction

Abstract

The invention discloses a pier stud template for road and bridge construction. The template comprises two half templates; T-shaped clamping grooves are formed in the ends, close to each other, of thetwo half templates. An I-shaped plate is inserted between the two adjacent clamping grooves; a top plate is fixed to the ends, away from the inner sides of the half templates, of the I-shaped plate, the end of the top plate extends to the outer sides of the outer walls of the half templates, two arc-shaped plates attached to the outer walls of the half templates are fixed to the outer side of eachhalf template, an inserting opening is formed in each arc-shaped plate in a communicating mode, and a U-shaped rod is arranged on the outer side of the joint of the two half templates. According to the invention, the I-shaped plate is inserted to connect and fix the half templates, so that a problem that loosening is likely to happen when an outer hoop is adopted for fixing traditionally is solved; separation of concrete from the joint of the baffle and the half template is achieved through continuous contact and impact between the impact ball and the half template and upward movement of thetop plate, so that rapid demolding is achieved, and damage to a wood plate or a pier stud is avoided.

Description

technical field [0001] The invention relates to the technical field of pier columns, in particular to a pier column formwork for road and bridge construction. Background technique [0002] Pier column, that is, the lower load-bearing object used to carry the upper structure in civil engineering. Most of the cross-sections of piers are circular, and there are also heterosexual piers such as ellipse, square, curve, and parabola. It is an important part of highway bridges, railway bridges, sidewalks and other bridges, overpasses, ramp bridges, overpasses and other projects. As an important part of bridges, pier columns have a profound impact on the overall stability of bridges in terms of appearance design and quality management. Impact. [0003] For the production of pier columns, the formwork is generally assembled first, then the external reinforcement of the formwork is carried out, and the release agent is applied on the inner wall of the formwork, and then the subsequen...

AI Technical Summary

Problems solved by technology

[0004] 1. The pier column is fixed by the outer frame or the outer hoop, and the outer frame is fixed by bolts, etc., which is easy to loosen itself, or the outer hoop expands and loosens due to the expansion of the concrete;

[0005] 2. Even if the release agent is applied, the uniformity cannot be guaranteed, and the pier column is still tightly attached to the inner wall of the formwork, which is not convenient for the subsequent removal of the formwork;

[0006] 3. The traditional method of directly pulling the formwork to the outside to remove the formwork, or damage to the formwork or pier due to the connection between the formwork and the pier
