Embodiment Construction

[0018] Such as figure 1 Among them, a concrete double-supported large-scale formwork, the lower end of the formwork 1 is hinged to the upper end of the triangular bracket 5, and the triangular bracket 5 is connected to the anchor bar 7 embedded in the concrete body;

[0019] The upper end surface of the tripod bracket 5 is connected to the back of the formwork 1 through at least two rows of first support adjustment screw rods 2 and second support adjustment screw rods 3 . The template 1 is over 4.5m in height. This results in a larger molding area.

[0020] In a further optimized solution, the second support adjustment screw 3 is located below the first support adjustment screw 2 .

[0021] The lower part of the triangular bracket 5 is provided with a plurality of diagonal braces 6, and each diagonal brace 6 corresponds to the force-bearing position of the first support adjustment screw 2 and the second support adjustment screw 3 respectively.

[0022] The formwork 1 has a ...

Abstract

A concrete double-bracing large-scale mold plate adopts the structure that two supporting points are formed on the back side of the mold plate, so as to improve the integral stress of a raising layer mold plate, reduce mold plate deformation during concrete construction, and enhance integral rigidity of the mold plate. During form stripping, one of the supporting points can be removed, so as to facilitate removing of the mold plate. Through the adoption of the structure, the height of the panel of the mold plate meets the construction requirements of a concrete dam block of a raising layer which is 4.5 m in height or higher; and a support adjusting screw rod capable of being disassembled fast and inclined strut rod pieces corresponding to a triangular bracket are additionally arranged on one side on the back of the panel of the mold plate, so as to realize fast form stripping and form erecting functions, adapt to dam concrete construction of the raising layer, remarkably improve the concrete casting construction speed, shorten dam construction cycle, and ensure that the project exerts benefits as soon as possible.

Description

technical field [0001] The invention relates to the field of concrete formwork, in particular to a double-supported concrete formwork and a method for dismantling and erecting the formwork. Background technique [0002] Cantilever formwork is widely used in the concrete pouring construction of power station dams and the formwork support of large-area vertical surfaces or steep slopes of high-side wall structures. More times, the concrete surface is well formed. The pouring height of the dam concrete is set in consideration of factors such as the structure of the hydraulic structure, foundation constraints, concrete temperature control, cooling water pipes, structural reinforcement design, embedded parts, and grouting divisions. The panel height of the cantilever formwork is generally determined according to the The height of the concrete rise is fixed. With the development of hydropower construction technology, various new dam building technologies have been widely used. T...
