A large-scale steel plate pre-embedded device and construction method for the floor

Abstract

The invention discloses a large-scale terrace steel plate embedding device. The large-scale terrace steel plate embedding device comprises a large-scale terrace steel plate, an embedded pipe, adjusting screws, adjusting nuts, a concrete feeding port and a booster pump. The adjusting screws are fixedly installed at four corner positions of the lower surface of the large-scale terrace steel plate and are installed in installing holes formed in the upper ends of embedded supporting columns through the adjusting nuts. The embedded supporting columns are fixedly installed on a positioning plate, the lower surface of the large-scale terrace steel plate is fixedly connected with the embedded pipe, and output holes are evenly distributed in the wall of the embedded pipe. The output end of the embedded pipe is connected with an interface of the booster pump. The concrete feeding port is formed in an output pipe of the booster pump. Large-area empty drums produced in the construction process of the large-scale terrace steel plate are effectively prevented, meanwhile the horizontal installing accuracy of the large-scale terrace steel plate is ensured, the construction efficiency is improved, and the construction progress is accelerated.

Description

technical field [0001] The invention relates to a construction device and a construction method, more specifically, to a pre-embedded device and a construction method of a large-scale steel plate on the floor. Background technique [0002] In the construction process of the large-scale floor steel plate, the large-scale floor steel plate is a cast-in-place reinforced concrete structure. The large-scale floor steel plate has a large amount of concrete when pouring, and the requirements for the flatness of the embedded parts are also high. At the same time, the buoyancy generated by pouring is large. These influencing factors all require precise leveling and positioning of the large steel plates on the floor. However, the large steel plate on the floor is a heavy steel plate. The traditional method of leveling the embedded parts is to directly pour concrete after adjusting the level of the large steel plate on the floor. If this method is used for construction, the blanking wi...

Problems solved by technology

However, the large steel plate on the floor is a heavy steel plate. The traditional method of leveling the embedded parts is to directly pour concrete after adjusting the level of the large steel plate on the floor. If this method is used for construction, the blanking will not be smooth during the concrete pouring process. Reduce construction efficiency; Insufficient vibration during construction and concrete shrinkage will cause a large area of ​​hollowing in the embedded steel plate; Readjustment is very troublesome and delays construction accuracy, increasing construction costs
