Elevating and installing method and device for T beam wet joint formwork

Abstract

The invention discloses an elevating and installing method and device for a T beam wet joint formwork. According to the method, before the wet joint formwork used for pouring a T beam wet joint is installed at a wet joint position of a T beam, the T beam wet joint formwork elevating and installing device is manufactured out in advance, and then the wet joint formwork is installed according to thefollowing steps. The method comprises the steps that firstly, the T beam wet joint formwork elevating and installing device is pushed to a wet joint of the T beam as a whole; secondly, the wet joint formwork, an opposite pulling screw rod, a butterfly clamp and double steel pipes are connected into a whole below the T beam; thirdly, after the opposite pulling screw rod to which a lifting ring is welded is connected with a lifting hook, a winch is started to elevate the wet joint formwork to the wet joint position of the T beam and enable the wet joint formwork to be closely attached to a flange plate of the T beam, then the butterfly clamp and the double steel pipes are used for fixing the wet joint formwork to the T beam; and the installing work can be completed by repeating the steps oneto three. The method and the device can effectively improve the conduction efficiency, save cost and reduce labor and lifting machines, and can effectively ensure the construction safety.

Description

technical field [0001] The invention relates to a method and device for lifting and installing a T-beam wet joint formwork, and belongs to the technical field of bridge T-beam construction equipment. Background technique [0002] The T-beam wet joint formwork of bridge engineering usually uses bamboo plywood formwork. In the formwork installation and construction, the existing T-beam wet joint formwork installation usually uses manual or small cranes for installation work; the T-beam wet joint formwork During the installation process, workers are usually required to go to the bottom of the wet joint to carry out construction work. Usually, it is necessary to install an operating platform at the lower part of the T-beam wet joint to facilitate and ensure construction safety. The existing T-wet joint formwork installation technology has low construction benefits and is very inconvenient to operate. It requires a lot of labor and crane shifts, and there are great safety risks i...

AI Technical Summary

Problems solved by technology

The existing T-wet joint formwork installation technology has low construction efficiency and inconvenient operation. It requires a lot of labor and crane shifts, and the safety risk is great during the operation.

In the installation and construction of the T-beam wet joint formwork, the construction efficiency is low, the operation is inconvenient, the use of hoisting equipment and the amount of labor is large, and safety accidents are prone to occur, and the formwork installation and the concrete surface of the T-beam wing plate cannot be closely fitted and joints are likely to occur and wrong station
