Overall dismantling and longitudinal slipping construction method of T beam formwork

Abstract

The invention discloses an overall dismantling and longitudinal slipping construction method of a T beam formwork. The method is characterized in that integrality of unilateral formworks is kept in formwork installation and dismantling of formworks and moving and transportation between beam manufacturing pedestals, and all segments do not need disconnecting; each unilateral formwork is provided with four sets of transverse slipping and longitudinal slipping bogies used for supporting the formworks in overall transverse slipping and longitudinal slipping processes of the T beam formwork; each unilateral formwork is provided with four sets of thorn wheels used for transversely slipping and is provided with formwork inclination angle regulation screw rods; the T beam formwork is provided with longitudinal slipping rails in a longitudinal moving mode and is pulled through a winch. The overall dismantling and longitudinal slipping construction method of the T beam formwork has the advantages of being strong in formwork integrality, easily guaranteeing the size of a beam body, not needing large-scale hoisting equipment in coordination for construction, saving labor force and lightening labor intensity.

Description

technical field [0001] The invention relates to a prefabricated T-beam construction method in railway and highway engineering construction, and specifically belongs to a T-beam formwork overall removal and longitudinal sliding construction method. Background technique [0002] In the traditional construction of T-beam formwork sub-projects, the formwork design and construction technology of domestic T-beam prefabrication are quite mature, and formwork is generally manufactured in sections, assembled in sections, dismantled in sections, and lifted in sections. The formwork segment length is generally 4m or 8m, and it is disconnected at the T-beam diaphragm; the formwork installation, removal, and transportation all require the assistance of lifting equipment such as gantry cranes; generally, each set of formwork is used with 2 or 3 beam-making pedestals , the beam-making cycle of the formwork is 2 to 3 days, and a gantry crane is required for every 2 to 3 sets of formwork. ...

AI Technical Summary

Problems solved by technology

[0003] During the construction of the formwork manufactured in sections, there are often cumulative errors caused by many joints in the formwork, resulting in excessive size deviation of the prefabricated beam body, and it is difficult to control the shape and appearance quality of the beam body; for each prefabricated T-beam, the formwork must be One-time installation, dismantling, hoisting and transportation, the construction process must rely entirely on the lifting gantry crane and the high-intensity labor of the operators; there are many steps in the process of installing, dismantling, and moving the formwork, and the construction efficiency is low. The use and intensive hoisting operations make the hoisting and hoisting operations as a high-risk source have a higher risk
