Description

Technical Field

[0001] The invention relates to the technical field of prefabricated T-beam formworks, and in particular to a movable prefabricated T-beam hydraulic formwork structure. Background Art

[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 ribs (or webs). It is formed by digging out the concrete in the tensile area of ​​the rectangular beam that does not contribute to the bending strength. In addition to having the same bending strength as the original rectangular beam, it can save concrete, reduce the deadweight of the component, and improve the spanning capacity; prefabricated beams 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 characteristics, T-beams are widely used in current road and bridge construction.

[0003] In order to realize the production and processing of T-beams with longer spans, the existing T-beam templates are generally composed of multiple template units connected end to end. When the template is opened and closed, each template unit is pushed to open and close by its own driving mechanism. Due to the large span of the T-beam, the T-beam is easily deformed or damaged due to uneven force on the front and rear sections when the mold is opened and closed.

[0004] In view of this problem, a Chinese patent (CN113183284A) discloses an automatic hydraulic synchronous opening and closing prefabricated T-beam template. Through automatic hydraulic synchronous opening and closing, the template exerts basically the same force on each part of the finished T-beam during mold closing and demolding, effectively avoiding deformation or damage of the finished T-beam. However, due to the large length span of the T-beam and the different structures of various parts, the contact area between the template and the T-beam is different. During the demolding process, the movement of multiple templates can easily cause the unstable position of the formed T-beam to shift, affecting the movement of the bottom mold.
