Problems solved by technology

However, for gate piers with a height ≥ 8m, most of the concrete construction of large and medium-sized sluice piers at home and abroad currently adopts layered and one-time pouring molding technology. The height of layered pouring is about 2.5-4m, and the construction of gate piers is generally divided into 2-4 times. To the top, the construction period is long, and there are many unsafe factors. During construction, it is easy to cause problems such as cold joints between concrete layers, wrong platform, large verticality deviation, and poor concrete appearance quality.

Abstract

The invention discloses a high and large concrete formwork reinforcing system. The high and large concrete formwork reinforcing system comprises two first channel steels, second channel steels, woodenboards, a steel formwork and split bolts. The edge portion of the steel formwork is provided with reinforced edges. The wooden boards are vertically arranged on the periphery of the steel formwork atintervals. The two opposite sides of the periphery of the wooden boards are transversely provided with the two first channel steels. The two ends of the two first channel steels are wrapped through fixed blocks. The two first channel steels are fixed through first fixed plates. The second channel steels are transversely arranged on the other two sides of the periphery of the wooden boards. The second channel steels are inserted in the gap between the two first channel steels. The second channel steels are fixed through second fixed plates. The corresponding positions of the wooden boards arefurther reinforced through split bolts. Each split bolt comprises gaskets, a cast steel nut and a screw rod, wherein the gaskets include the first gasket and the second gasket; the first gasket is square, and the second gasket is arc-shaped. The first gaskets are arranged on the corresponding sides of the first channel steels, and the second gaskets are arranged on the corresponding sides of the second channel steels. The high and large concrete formwork reinforcing system effectively improves the appearance quality and has high practicality.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a tall concrete formwork reinforcement system. Background technique [0002] The gate pier, dam body, wall, etc. of hydraulic structures have high requirements on the appearance quality of the exposed surface, so the formwork must be used during the construction process. The design and construction of the formwork vertical formwork system are also constantly innovating. However, for gate piers with a height ≥ 8m, most of the concrete construction of large and medium-sized sluice piers at home and abroad currently adopts layered and one-time pouring molding technology. The height of layered pouring is about 2.5-4m, and the construction of gate piers is generally divided into 2-4 times. To the top, the construction period is long and there are many unsafe factors. During construction, it is easy to cause problems such as cold joints between concrete layers, wrong platform, lar...
