Connecting and fixing method for lining die of high bridge pier roller die

Abstract

The invention discloses a connecting and fixing method for a lining die of a high bridge pier roller die. The technical scheme includes that a connecting and fixing device comprises equilateral angle steel, mounting notches and a rubber lining, wherein the equilateral angle steel wraps the high-density rubber lining, and the high-density rubber lining comprises the rubber mounting notches and an inner curved surface. During template splicing, a lining template is mounted in the rubber mounting notches of the device, the equilateral angle steel is positioned on the outer side to contact with a wheel axle directly, and the inner curved surface is positioned on the innermost side and contacts with concrete directly. The chamfer connecting and fixing device for the lining die of the high bridge pier roller die has the advantages that the device is portable, flexible to move, convenient to mount and excellent in connecting and fixing effects, mounting of the lining template is accelerated, the lining die at a chamfer position of a pier is convenient and compact to connect during roller die construction, the problem that the macromolecular resin lining die at the arc-shaped chamfer position of the pier is difficult to fix and connect is solved, construction progress can speed up, pier concrete appearance quality is guaranteed and economic benefit created by roller die construction is improved.

Description

technical field [0001] The invention relates to a bridge construction method, in particular to a method for connecting and fixing roller mold inner lining molds for high bridge piers. Background technique [0002] The roller formwork construction method for high bridge piers is a new type of pier column construction method, which has the advantages of fast construction speed, good appearance quality, high safety, and obvious economic benefits. The roller formwork construction method uses the separation of the inner lining formwork and the formwork outer frame During the sliding process, the inner lining form and the concrete surface are relatively static, ensuring that the concrete will not be disturbed and rubbed during the lifting process of the outer frame, ensuring the appearance quality of the concrete, and at the same time ensuring the durability of the concrete. The compactness of the connection of the lining formwork directly affects the appearance quality of the pie...

[0003] However, the connection of the resin plate-lined formwork cannot be fixed with bolts like the steel formwork, and can only be reinforced by a special connection method. On the plane, the resin plates are connected by tongue-and-groove connection, which can effectively guarantee the compactness, but the pier column chamfer It is arc-shaped, and the resin plate has high strength and cannot be directly bent and formed. Therefore, it is necessary to invent a method for connecting and fixing the chamfer of the lining mold to ensure the effective connection of the lining mold, so as to ensure the good appearance quality of the pier column under construction.
