Detailed Description
In the following, the technical solutions of the present invention will be described clearly and completely, and it is obvious that the described embodiments are some, not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
Referring to fig. 1-2, a temporary support device with variable height for a narrow space comprises:
the base plate 100 is horizontally arranged, and the cross section of the base plate 100 is U-shaped;
the limiting cylinder 200 is vertically arranged, and the lower end of the limiting cylinder 200 is welded on the base plate 100; in this embodiment, 2 limiting cylinders 200 are arranged on the base plate 100 at intervals, a reinforcing plate 201 is arranged between 2 limiting cylinders 200, the lower end of the reinforcing plate 201 is welded on the base plate 100, and the two sides of the reinforcing plate are welded on the outer wall of the limiting cylinder 200 at the corresponding position;
the lower end of the supporting steel bar 300 is inserted into the limiting cylinder 200; the diameter of the supporting steel bar 300 is equal to the inner diameter of the limiting cylinder 200;
the positioning ring 400 is sleeved on the supporting steel bar 300 and is in threaded fit with the supporting steel bar 300, and it is not difficult to know that the supporting steel bar 300 and the positioning ring 400 are provided with threads which are matched with each other; the lower end of the positioning ring 400 is abutted against the top of the limiting cylinder 200, and in addition, the outer wall of the positioning ring 400 is symmetrically provided with adjusting handles 401.
The following briefly explains the method of using the temporary support device in this embodiment:
the temporary supporting device in the embodiment is firstly placed in place between the prefabricated beam installation templates, and the design standard height of the prefabricated beam bottom web template is calculated through measurement. And then adjusting the depth of the supporting steel bars 300 penetrating into the limiting cylinder 200 to enable the top of the supporting steel bars to reach the design standard height of the prefabricated beam bottom web plate template, thereby realizing the temporary supporting function. After the precast beam is poured and reaches the corresponding strength, the depth of the supporting steel bar 300 penetrating into the limiting cylinder 200 is adjusted, the top of the supporting steel bar is separated from the template, then the whole temporary supporting device is taken out, and finally the template is detached.
