Side template vertical support anti-loose device

Abstract

The invention discloses a side template vertical support anti-loose device. The device comprises a top supporting block, a threaded rod and a base, the top supporting block is used for connecting side templates and located above the base, the top supporting block is connected with the threaded rod in a screw mode, and the lower portion of the threaded rod is inserted onto the base in a penetrating mode; a limit rod is fixedly connected to one side of the threaded rod, and a limit sleeve is fixedly connected to the limit rod; the anti-loose device further comprises a stop pin, a guide hole is formed in the base, the threaded rod penetrates through the guide hole, multiple stop pin holes are evenly distributed in the base in the mode of surrounding the guide hole, and the stop pin holes are matched with the stop pin; when the stop pin penetrates through the limit sleeve and is inserted into some stop pin hole, the threaded rod cannot rotate under the effect of external forces; when the stop pin is not inserted into some stop pin hole, the threaded rod can rotate under the effect of the external forces. The side template vertical support anti-loose device achieves circular fixation of the threaded rod in the working process and guarantees effective vertical supporting for the side templates.

Description

technical field [0001] The invention belongs to the technical field of concrete pouring, in particular to an anti-loosening device for the vertical support of a side formwork. Background technique [0002] The vertical support of the side formwork is a device used to support the side formwork during the concrete pouring process so that the position of the formwork will not move due to concrete pouring, workers' stepping, etc. [0003] In the process of concrete pouring, in order to ensure that the interior of the concrete is dense and the surface is smooth and free of defects, most of the attached high-frequency vibrators are used for vibration, and the attached high-frequency vibrators must be fastened to the outside of the side formwork. The frequency of the attached vibrator is high and the vibration energy is large. If three or more vibrators are turned on at the same time, the template will vibrate obviously. For the convenience of processing and use, the vertical supp...

AI Technical Summary

Problems solved by technology

Under the action of high-frequency vibration, the thick threaded rod is very easy to reverse the screw thread, which will cause the vertical support height of the outer formwork to change, and then cause the concrete to separate from the formwork prematurely, and the concrete surface will stick to the mold and the structure will appear obviously. Defects such as dimensional deviation or even quality problems
