Large-span concrete construction cantilever formwork structure

Abstract

The invention discloses a large-span concrete construction cantilever formwork structure, and belongs to a construction cantilever structure. The large-span concrete construction cantilever formwork structure comprises a floor plate and a wall body, a motor is connected to the wall body, the output end of the motor is fixedly connected with a worm, a worm wheel and a rack, and the bottom of the rack is fixedly connected with a fixed block and a platform sliding plate; and a fixed plate is arranged on the floor plate, a U-shaped anchor bolt and an L-shaped anchor bolt are connected to the fixedplate, an alarm lamp is connected to the exterior of a rightmost fixed rod, a steel rope is connected to the front side of the sliding plate, a turn buckle is arranged in the middle of the steel rope, a load-bearing sensor is fixedly connected into the right side of the fixed plate, and a weight display screen is fixedly connected to the right end of the fixed plate. Compared with the prior art,the large-span concrete construction cantilever formwork structure has the beneficial effects that the structure is simple, use is convenient, the weight display screen is arranged, workers can conveniently observe the material weight of a platform, the construction and installation speed is high, and the operation safety is high.

Description

technical field [0001] The invention relates to a construction cantilever structure, in particular to a large-span concrete construction cantilever formwork structure. Background technique [0002] Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in appropriate proportions, uniformly stirred, compacted and cured. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. The strength grade of concrete is divided by the standard value of cubic compressive strength. [0003] With the rapid development of the construction industry, the proportion of high-rise cast-in-place concrete building structures is increasing day by day, and various construction auxiliary tools and equipment ar...

Problems solved by technology

The construction cantilevered platform, which is easily overlooked in building construction, but also relatively important, has been in a relatively backward situation. For the main direction of architectural design today, the shortcomings of the original fixed cantilevered platform are directly revealed. The fixed cantilevered platform The hanging platform is cantilevered on the outside of the building, mainly supported by steel pipes or other profiles, attached to the working layer of the building, pulled and fixed by the steel wire rope and the embedded point in the building, and cantilevered out of the blanking platform outside the building to cause The devices on the upper and lower floors interfere with each other, and the devices must be staggered to avoid materials being unable to reach the corresponding operation level due to overlapping devices.
