Abstract

The invention relates to the bridge T-shaped beam construction field, especially a method for erecting T-shaped beam by using small-sized machinery. The method comprises following steps: step 1, a jacking device and a moving device are manufactured; step 2, the jacking device is installed; step 3, the moving device is installed; step 4, the T-shaped beam is moved; step 5, the T-shaped beam is erected. By using the method provided by the invention, when a bridge girder erection machine, a T-shaped beam, or a crane cannot enter the construction site, the jacking device and a translating device can be used to erect the T-shaped beam, and can be manufactured on site, and in addition, assembly is simple, installation is convenient, and operation is easy. A special supporting device is provided,and under a precondition of guaranteeing the safety performance, the erection operation of the T-shaped beam can be completed simply and conveniently, and therefore construction difficulty, construction costs and construction safety hidden troubles are reduced.

Description

technical field [0001] The invention relates to the field of bridge T-beam construction, in particular to a method for erecting T-beams using small machines. Background technique [0002] At present, T-beams are generally used in the laying of bridges. The reason is that the T-beams are equivalent to digging out the concrete in the tensile area of ​​the rectangular beams that does not play a role in the flexural strength. It is completely different from the original rectangular flexural strength. In addition to the same, it can not only save concrete, but also reduce the self-weight of components, and improve the spanning ability. [0003] Such as figure 1 As shown, the protruding parts on both sides of the T-beam 4 are called flanges 42 , and the middle parts are called webs 41 . [0004] For the erection of T-beams, because the single-piece T-beams used as bridges are very heavy, quantitative production of beam yards and bridge erecting machines are usually used for erec...
