Prefabricated T-beam formwork capable of automatic hydraulic synchronous opening and closing

Abstract

The invention discloses a prefabricated T-beam formwork capable of automatic hydraulic synchronous opening and closing. The formwork comprises a formwork base, a plurality of formwork units which are sequentially connected end to end are fixedly arranged at the top of the formwork base, each formwork unit comprises two symmetrically-arranged side mold pressing parts, a prefabricated steel plate is embedded in the formwork base, each side mold pressing part comprises a mold removing support, one end of the mold removing support is welded to the prefabricated steel plate, a bottom opening and closing jack is fixedly arranged at the top of the mold removing support, a side mold framework is connected to the output end of the bottom opening and closing jack through a pin shaft, and the bottom of the side mold framework is slidably connected with a mold plate base. According to the prefabricated T-beam formwork capable of automatic hydraulic synchronous opening and closing, automatic hydraulic synchronous opening and closing can be achieved, so that when the prefabricated T-beam formwork carries out mold closing and mold removing, acting force on all parts of a finished T-beam is basically consistent, and deformation or damage of the finished T-beam is effectively avoided.

Description

technical field [0001] The invention relates to a T-beam formwork, in particular to an automatic hydraulic synchronous opening and closing prefabricated T-beam formwork. Background technique [0002] T-beam refers to a beam with a T-shaped cross-section. The protruding parts on both sides are called flanges, and the middle part is called beam rib (or web). Because it is equivalent to digging out the concrete in the tension zone of the rectangular beam that does not play a role in the flexural strength. While the bending strength of the original rectangle is exactly the same, it can not only save concrete, but also reduce the self-weight of the component and improve the spanning capacity; the prefabricated beam can be processed in the factory, and then transported to the designated construction site for assembly, so it can Effectively shorten the construction period. Due to its many excellent features, T-beams are widely used in road and bridge construction. [0003] In or...

Problems solved by technology

[0003] In order to realize the production and processing of T-beams with longer spans, the existing T-beam formwork is generally composed of multiple formwork units connected end to end. When the formwork is opened and closed, each formwork unit is driven by its own drive mechanism. Opening and closing, due to the large length and span of the T-beam, the T-beam is prone to deformation or damage due to uneven force on the front and rear sections when the mold is opened and closed, and the existing T-beam formwork can only be hoisted by the steel skeleton. Continuously moving the hoisting equipment to move and assemble the steel frame in different positions, the construction operation is inconvenient, and at the same time, the accuracy of the control of the installation position of the steel frame is insufficient
