T-beam combined steel template mounting and dismounting structure and method

Abstract

The invention discloses a T-beam combined steel template mounting and dismounting structure and method. The T-beam combined steel template mounting and dismounting structure comprise a steel templatefixing and adjusting device, a lifting electromagnet and a lifting tripod, wherein the steel template fixing and adjusting device is arranged at an installation position of the steel template, the lifting tripod is fixed on a lifting ring, a lifting chain of the lifting electromagnet is connected to the same lifting ring, the lifting tripod hooks the steel template from the side surface, and the lifting electromagnet is attracted to the upper end of the steel template. According to the T-beam combined steel template mounting and dismounting structure and method, the lifting electromagnet is used for mounting and dismounting the steel template, and compared with the direct lifting and mounting without the lifting electromagnet, the stability of the steel template is ensured and the method is rapid, convenient and labor-saving. The steel template fixing and adjusting device with a self-adhesive rubber pad can be adjusted in time according to different heights, can be used in a multi-siteturnover mode and is fast to be adjusted, and steel template steel plate type bottom feet fall on the rubber pad with good stability. According to the T-beam combined steel template mounting and dismounting structure and method, the advantages are more embodied in a narrow prefabricated site, compared with an overall template with rollers, the moving requirement is much less, a large site is notneeded, and the mounting and dismounting device used in the mounting method is small in size and convenient to move.

Description

technical field [0001] The invention relates to a bridge steel formwork, in particular to a structure and method for installing and dismantling a T-beam composite steel formwork. Background technique [0002] At present, many bridge designs use T-beams, and the construction of cast-in-place T-beams is difficult. Generally, custom-made combined steel formwork is used to prefabricate T-beams. A beam is generally divided into 2-6 pieces of steel formwork, and the weight of each piece is generally 1.5-3t. Since they are all steel Production, transportation and installation are laborious and not stable. Most precast yards use gantry cranes to directly lift the steel formwork, and the foot of the formwork is adjusted with wooden squares, which is time-consuming and laborious, and the stability is poor. Contents of the invention [0003] The purpose of the present invention is to overcome the defects existing in the prior art, and provide a structure and method for installing and...

A beam is generally divided into 2-6 pieces of steel formwork, and the weight of each piece is generally 1.5-3t. Since they are all steel Production, transportation and installation are laborious and not stable. Gantry cranes are often used to directly lift the steel formwork in the prefabrication yard. The foot of the formwork is adjusted with wooden squares, which is time-consuming and laborious, and the stability is poor.
