Pier column template

Abstract

The utility model provides a pier column formwork. The pier column formwork comprises formwork blades and a connecting mechanism. The ends of the multiple formwork blades abut against one another so that a formwork for pouring the pier column can be defined. Connecting parts protruding outwards are arranged at the abutting positions of every two adjacent formwork blades, grooves are formed in the outer sides of the connecting parts, and guiding faces inclining outwards are arranged in the grooves; a connecting mechanism is arranged at the position of every two adjacent connecting parts, and each connecting mechanism comprises a pulling piece, a pushing piece and a driving piece; the pulling piece is arranged in a U shape, and guiding protrusions are arranged on the two opposite inner sides of the pulling piece correspondingly. The two connecting parts are clamped in the pulling piece in a sliding manner; the guide protrusions are located in the grooves and abut against the guide faces in a sliding mode. The pushing piece is slidably mounted in the pulling piece, and the pushing piece is located between the connecting part and the pulling piece; the driving piece can drive the pulling piece and the pushing piece to move oppositely. And after the driving piece is loosened, the connecting part is still clamped by the two sides of the pulling piece, so that a larger gap can be effectively prevented from being generated.

Description

Technical Field

[0001] The utility model relates to the technical field of bridge pier columns, and in particular to a bridge pier column template. Background Art

[0002] Piers are the lower load-bearing objects used to support the upper structure in civil engineering. The cross-section of piers is mostly circular, but there are also elliptical, square, curved, parabolic and other special piers. They are important components in highway bridges, railway bridges, pedestrian bridges, overpasses, ramp bridges, flyovers and other projects. As an important part of the bridge, the appearance design and quality management of the pier have a profound impact on the overall stability of the bridge.

[0003] When making pier columns, the formwork is usually assembled first, and then the outer part of the formwork is reinforced, and the release agent is applied to the inner wall of the formwork, and then the subsequent concrete pouring is carried out. After the pier column concrete is hardened and finalized, the formwork is removed. However, the existing pier column forming formwork still has the following problems:

[0004] The casting of traditional piers mainly uses multiple arc-shaped formwork blades that are buckled together and connected by bolts to form a formwork for casting the piers; however, since the bolts are prone to loosening, a large gap is likely to be generated between two adjacent formwork blades when the bolts are loose. Utility Model Content

[0005] In view of the above problems existing in the prior art, the technical problem to be solved by the utility model is: since the bolts are prone to loosening, when the bolts are loosened, a large gap is likely to be generated between two adjacent template blades.

[0011] Preferably, a plurality of driving members are arranged at intervals in the length direction of the pushing member.

[0012] Preferably, a triangular reinforcement piece is installed at the corner of the pulling member; a plurality of the triangular reinforcement pieces are arranged at intervals in the length direction of the pulling member; and a corresponding position on the pushing member is provided with an avoidance groove cooperating with the triangular reinforcement piece.

[0013] Preferably, sliding grooves are respectively provided on the two opposing inner side surfaces of the pulling member; a sliding member is slidably installed in the sliding groove, one end of the sliding member is fixedly connected to the pushing member, and a limiting member is fixedly installed on the other end of the sliding member, and the limiting member is slidably abutted against the pulling member.
