Description

Temporary fixing method for fire-fighting stand pipe

Technical Field

The invention belongs to the technical field of construction of temporary fire fighting pipes of frame structures, and particularly provides a temporary fixing method of a fire fighting stand pipe.

Background

When the frame structure is constructed, the temporary fire fighting vertical pipe is generally welded and fixed by the stay bars and the frame steel columns, and the method has two defects, namely, the left and the right of the fixed fire fighting vertical pipe cannot be adjusted, and the use of the fire fighting pipe is limited; secondly, the supporting rods of the disassembled fire-fighting vertical pipe need to be cut by gas welding, so that the vertical pipe is easy to cause local damage and can not be reused, and the construction cost is increased.

Disclosure of Invention

The invention aims to provide a temporary fixing method of a fire fighting riser, which solves the problems that the left and right sides of the fixed fire fighting riser can not be adjusted, and the fire fighting pipe has limitation in use; the supporting rods of the disassembled fire-fighting stand pipe need to be subjected to gas welding cutting, so that the stand pipe is easy to cause local damage and cannot be reused, and the problems of construction cost increase and the like are caused.

The positioning of the C-shaped clamp is adjusted up and down by utilizing the looseness of the C-shaped clamp screw, and meanwhile, the left and right adjustment of the fire-fighting stand pipe is met by utilizing 5 round holes in the shoulder pole. The use of the fire-fighting riser is more flexible. The specific process steps are as follows:

firstly, processing a C-shaped card 1 and a carrying pole 4, wherein the C-shaped card 1 is processed by a 6mm steel plate, the carrying pole 4 is processed by 60mm equilateral angle steel, and 5 circular holes with equal intervals are formed in one surface of the angle steel; then fixing the C-shaped clamp 1 with a flange plate of a steel column 3 through a screw 2, and adjusting the positioning of the C-shaped clamp 1 up and down through loosening the screw 2 (figure 1);

secondly, welding and fixing the carrying pole 4 and the C-shaped clamp 1, enabling the carrying pole 4 to be tightly attached to the temporary fire-fighting vertical pipe 6, then clamping the fire-fighting vertical pipe 6 by utilizing a U-shaped bolt 5, and penetrating through two round holes in the carrying pole 4 for fixing (shown in figures 2, 3 and 4);

thirdly, when the fire-fighting vertical pipe 6 needs to be adjusted left and right, the U-shaped bolt 5 is loosened, and then the U-shaped bolt 5 is inserted into the other two round holes of the carrying pole 4. When the fire fighting riser 6 is not used any longer, the nuts of the bolt 2 and the U-bolt 5 of the C-shaped clamp 1 are loosened, and then the fire fighting riser 6 is protectively removed without being damaged. The removed C-clamp 1, U-bolt 5 and fire riser 6 can be reused (fig. 5, 6).

The method is simple and easy to operate, the C-shaped clamp is vertically adjusted by loosening the C-shaped clamp screw, and meanwhile, the left and right adjustment of the fire-fighting stand pipe is met by using 5 round holes in the shoulder pole. The use of the fire-fighting stand pipe is more flexible, the disassembled C-shaped clamp, U-shaped bolt and the fire-fighting stand pipe can be reused, manpower and material resources are saved, construction cost is greatly reduced, and good economic benefits are obtained for companies.

Detailed Description

Fig. 1-6 illustrate an embodiment of the present invention. The specific implementation mode is as follows:

firstly, a C-shaped clamp 1 and a carrying pole 4 are machined, the C-shaped clamp 1 is machined by a 6mm steel plate, the carrying pole 4 is machined by 60mm equilateral angle steel, and 5 circular holes with equal intervals are formed in one surface of the angle steel. Then fixing the C-shaped clamp 1 with a flange plate of a steel column 3 through a screw 2, and adjusting the positioning of the C-shaped clamp 1 up and down through loosening the screw 2;

secondly, welding and fixing the carrying pole 4 and the C-shaped clamp 1, enabling the carrying pole 4 to be tightly attached to the temporary fire-fighting vertical pipe 6, then clamping the fire-fighting vertical pipe 6 by utilizing a U-shaped bolt 5, and penetrating through two round holes in the carrying pole 4 for fixing;

thirdly, when the fire-fighting vertical pipe 6 needs to be adjusted left and right, the U-shaped bolt 5 is loosened, and then the U-shaped bolt 5 is inserted into the other two round holes of the carrying pole 4. When the fire fighting riser 6 is not used any longer, the nuts of the bolt 2 and the U-bolt 5 of the C-shaped clamp 1 are loosened, and then the fire fighting riser 6 is protectively removed without being damaged. The removed C-clamp 1, U-bolt 5 and fire riser 6 can be reused.

When the frame structure of the sintering main factory building is constructed, a temporary fixing method is adopted for the temporary fire-fighting stand pipe, and a good effect is achieved. The C-shaped clamp and the carrying pole rod are machined firstly, the carrying pole rod is formed by machining angle steel, 5 circular holes are formed in one surface of the angle steel at equal intervals, the C-shaped clamp is fixed with the steel column flange plate through screws, and the positioning of the C-shaped clamp is adjusted up and down through loosening the screws. The carrying pole is welded and fixed with the C-shaped clamp, the carrying pole is tightly attached to the temporary fire-fighting vertical pipe, then the fire-fighting vertical pipe is clamped by the U-shaped bolt and passes through two round holes of the carrying pole to be fixed, when the fire-fighting vertical pipe needs to be adjusted left and right, the U-shaped bolt is loosened, and then the U-shaped bolt is inserted into the other two round holes of the carrying pole. When the fire-fighting stand pipe is not used any more, the C-shaped clamping screw and the nut of the U-shaped bolt are loosened, and then the fire-fighting stand pipe is protectively dismounted without being damaged. The removed C-shaped clamp, U-shaped bolt and fire-fighting riser can be reused. The method is simple and easy to operate, the C-shaped clamp is vertically adjusted by loosening the C-shaped clamp screw, and meanwhile, the left and right adjustment of the fire-fighting stand pipe is met by using 5 round holes in the shoulder pole. The use of the fire-fighting stand pipe is more flexible, the disassembled C-shaped clamp, U-shaped bolt and the fire-fighting stand pipe can be reused, manpower and material resources are saved, construction cost is greatly reduced, and precious experience is accumulated for later similar construction.
