Description
Technical Field
[0001] The utility model belongs to the technical field of prefabricated stair supports, in particular to a temporary support device for prefabricated stairs. Background Art
[0002] With the development of modern industrial technology, prefabricated buildings are increasingly used in construction projects. The characteristics of prefabricated buildings are that a large number of building components are produced and processed in workshops, a large amount of assembly work is done on site, and decoration can be carried out simultaneously with the main construction.
[0003] During the installation process of existing prefabricated stairs, the prefabricated stairs are usually hoisted first and then installed. However, after the prefabricated stairs are hoisted, the workers will leave the prefabricated stairs for a long time. Since the prefabricated stairs are heavy, long-term hoisting will cause structural damage to the prefabricated stairs, and they will shake and fall, affecting subsequent construction. Therefore, we propose a temporary support device for prefabricated stairs. Utility Model Content
[0004] The purpose of the utility model is to provide a temporary support device for prefabricated stairs, which provides a support component, specifically, placing a support column at the bottom of the prefabricated stairs, and then pulling the push block to drive the limit plate to move to the right, and the lifting column moves upward under the elastic action of a spring, so that the card plate contacts the bottom of the prefabricated stairs, and then the bolt is turned clockwise to fix the lifting column to complete the temporary support, thereby avoiding the prefabricated stairs from shaking or falling, protecting the prefabricated stairs from damage, and solving the problem that the long-term lifting of the existing prefabricated stairs will cause structural damage to the prefabricated stairs, and shaking will cause falling, affecting subsequent construction.
