Detailed Description

The invention will be further described with reference to the drawings and the following examples, but the scope of the invention is not limited thereto.

As shown in figure 1, interim strutting arrangement of basement roof back shore steel column, including steel column 1, otic placode 2, high strength bolt 3, steel sheet 4, nut and concrete foundation 6. Steel column 1 is prefabricated in the mill and is accomplished, and steel column 1 is hollow circular cylinder structure, and the round steel plate has all been welded at 1 both ends of steel column in order to realize sealing, and the horizontal welding of the symmetry department of 1 bottom 30cm position department of steel column has two otic placodes 2, and the diameter and the length of steel column 1 are selected according to the mechanics calculation result under the actual construction scene.

As shown in fig. 1, a steel plate 4 is arranged at a supporting point below a top plate 5 of the basement, and four corners of the steel plate are temporarily fixed by adopting common steel pipes and jacking supports; the top of the steel column 1 tightly supports the steel plate 4, the lower end of the steel column 1 is buried in a concrete base 6 on a basement bottom plate, and the depth of the steel column 1 inserted into the concrete base 6 is larger than 10 cm. In addition, two high-strength bolts 3 are symmetrically embedded in the concrete bases 6 on two sides of the steel column 1, the upper ends of the high-strength bolts 3 penetrate through mounting holes in the lug plates 2 and are limited and fixed through nuts, and the nuts are located on the high-strength bolts 3 below the lug plates 2. Before concrete foundation 6 pours, through adjusting nut, can exert pressure the top tightly with steel column 1, further guarantee the support effect. And after the concrete base 6 is poured and finally set, removing the common steel pipes and the jacking supports for temporarily fixing the periphery of the steel plate 4.

In this embodiment, preferably, the steel plate 4 is rectangular, the plane size of the steel plate is 1 × 1M, the thickness of the steel plate is 5mm, the high-strength bolt 3 is an M30 high-strength bolt 3, and the concrete foundation 6 is formed by pouring concrete with a strength grade of C30.

In actual construction, firstly, a steel column 1 with a proper size is selected according to the mechanical calculation of foundation top return, then, the two ends of the steel column 1 are sealed and processed in a factory, ear plates 2 are welded, after raw materials enter the field, the steel column 1 is inspected by a technical department and an administrative unit, and the thickness and the length of the pipe wall of the steel column 1 are rechecked to check whether cracking, warping and the like exist.

After rechecking is qualified, performing on-site measurement and paying off, mounting a steel plate 4 at the supporting position of a top plate 5 of the basement, and temporarily fixing four corners of the basement by adopting common steel pipes and jacking supports; then, a steel column 1 is arranged below the steel plate 4, a high-strength bolt 3 is arranged, and the steel column 1 is pressed and tightly pressed through an adjusting nut, so that the steel column 1 tightly presses the steel plate 4. And then, erecting templates around the lower part of the steel column 1, pouring C30 concrete, vibrating to compact, removing the templates after the concrete is finally set, maintaining on time to form a stable concrete base 6, and removing common steel pipes and jacking supports for temporarily fixing the periphery of the steel plate 4. When the basement top plate 5 does not need to be supported any more, the concrete base 6 is chiseled off, and then the steel column 1, the steel plate 4 and the high-strength bolt 3 are unloaded through adjusting the screw cap.

The embodiment is a preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and any obvious improvement, replacement or modification which can be made by those skilled in the art without departing from the essence of the present invention belongs to the protection scope of the present invention.
