Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction auxiliary equipment, and more specifically, to a prefabricated T-beam anti-overturning device. 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.

[0003] In the prior art, T-beams are very common in construction projects and daily life, and are part of the walls of construction projects. After most of the existing T-beams are prefabricated and the molds are ready for removal, workers will install wooden poles under the flange plates on both ends of the T-beams to support them in order to prevent the T-beams from tilting or falling. However, when the wooden poles are placed at both ends of the T-beams to support them, they are generally large in size and heavy in weight, making them too inconvenient to use, and require multiple workers to work together at the same time, which is not only time-consuming and labor-intensive, but also inefficient and costly. In addition, in the above scheme, the top frame and the columns cannot be smoothly adjusted in height according to the height of the T-beam when in use.

[0004] In response to the above-mentioned problems, a support device for a prefabricated T-beam to prevent overturning is disclosed in Chinese Patent Publication No. CN219653532U. One end of the convenient support device to prevent the prefabricated T-beam from overturning is detachably inserted in the armpit of the T-beam, and the other end is detachably inserted in the foundation to form a stable triangular support. Support devices are set on both sides of the prefabricated T-beam to prevent the T-beam from overturning. This structure solves the problems of traditional prefabricated T-beam support to a certain extent. However, it not only requires expansion screws to be driven into the ground, but also requires grooves to be dug in the ground, which makes its installation inconvenient. At the same time, the diagonal brace is subjected to greater force and is prone to deformation, which affects its support effect. Utility Model Content
