[0028] See also Figure 2 、 Figure 3 and Figure 4The pipe clamp 2 includes an upper clamp 21 and a lower clamp 22, and a rubber ring 23 is fixed on the upper clamp 21 and the lower clamp 22. A plurality of adjusting nuts 211 are threadedly connected to the upper clamp 21, and one end of the adjusting nut 211 is ball-hinged with a pressure block 212. The pipe 3 is clamped and fixed by the bracket 221, so that the pipe clamp 2 can be applied to pipes 3 of different diameters. The inner wall of the upper clamp 21 begins to have a groove corresponding to the pressure block 212. The pressure block 212 is placed in the groove to ensure that the pressure block 212 fits the upper clamp 21 without protrusion. When the diameter of the pipe 3 is smaller than the diameter of the ring between the upper clamp 21 and the lower clamp 22, the pressure block 212 is placed in the groove to ensure that the pressure block 212 fits the upper clamp 21 without protrusion. When the diameter of the pipe 3 is smaller than the diameter of the ring between the upper clamp 21 and the lower clamp 22, the pressure block 212 is tightened by the bracket 221. The adjusting nut 211 is turned to push out the pressing block 212 so that the pressing block 212 fits the pipe 3 and clamps the pipe 3 to fix the pipe 3 and prevent a gap from appearing between the pipe 3 and the upper clamp 21 and the lower clamp 22. The lower end of the lower clamp 22 is fixed with two brackets 221 arranged in an eight-shaped shape, and a reinforcing rib 223 is provided between the two brackets 221. The lower end of the bracket 221 is fixed with a connecting plate 222, and the lower end of the lower clamp 22 is fixed with two left-right symmetrical vertical plates 228, and a number of fixing plates 224 are fixed on the vertical plates 228. The lower ends of the vertical plates 228 are respectively fixed with fixing heads 227.

[0029] See also Figure 2 、 Figure 3 and Figure 4 , the area of ​​several fixing plates 224 decreases from top to bottom, the upper end of each fixing plate 224 is provided with an anti-slip strip 225, and each fixing plate 224 is provided with a through hole 226. The shape of the fixing head 227 is an arrow pointing downward. The fixing plate 224 and the fixing head 227 are inserted into the column 11 to increase the contact area and ensure the firmness of the connection between the lower clamp 22 and the column 11. When pouring the reinforced concrete frame 1 and the column 11, the lower clamp 22 is directly inserted before it solidifies. 2 is inserted therein, and the arrow-shaped fixing head 227 can quickly insert the lower clamp 22 into the upper end of the column 11. At the same time, the through hole 226 on the anti-slip strip 225 allows concrete to pass through, so that the concrete fits with the fixing plate 224 and the anti-slip strip 225. After the concrete is completely solidified, the lower clamp 22 is fixedly connected to the column 11. At the same time, the anti-slip strip 225 on the fixing plate 224 increases the friction between the lower clamp 22 and the column 11, further tightening the lower clamp 22 to prevent the lower clamp 22 from separating from the column 11.

[0030] See also Figure 2 、 Figure 3 and Figure 4The upper clamp 21 and the lower clamp 22 are fixed by bolt connection, and the inner wall of the rubber ring 23 is provided with a plurality of convex rings. By providing the convex rings on the inner wall of the rubber ring 23, when hot air passes through the pipe 3, the pipe 3 will expand and contract with heat, and the deformation of the convex rings of the rubber ring 23 is used to relieve the deformation of the pipe 3, preventing the lower clamp 22 and the upper clamp 21 from cracking the pipe 3, or preventing a gap from appearing between the pipe 3 and the upper clamp 21 and the lower clamp 22. The upper end of the connecting plate 222 is provided with a plurality of fixing holes, and the reinforcing ribs 223 are fixedly connected to the lower clamp 22 and the connecting plate 222. A fixing hole is provided on 22, and the connecting plate 222 and the column 11 can be fixed by fixing parts such as steel nails to further improve the firmness of the connection. At the same time, the reinforcing rib 223 reinforces the connection of the lower clamp 22 to prevent the lower clamp 22 from being separated from the connecting plate 222. The lower clamp 22, bracket 221, connecting plate 222, reinforcing rib 223, fixing plate 224, anti-slip strip 225, fixing head 227 and vertical plate 228 are integrally formed by a casting process to ensure the firmness of the connection. The reinforced concrete frame 1 and the column 11 are integrally formed to ensure the firmness of the connection.

[0031] When using this utility model:

[0032] First, the reinforced concrete frame 1 and the column 11 are cast through a mold. When the reinforced concrete frame 1 and the column 11 are cast, the lower clamp 22 is directly inserted into them before they solidify. The arrow-shaped fixing head 227 can quickly insert the lower clamp 22 into the upper end of the column 11. At the same time, the through hole 226 on the anti-slip strip 225 can allow concrete to pass through, so that the concrete fits with the fixing plate 224 and the anti-slip strip 225. After the concrete is completely solidified, the fixed connection between the lower clamp 22 and the column 11 is achieved. At the same time, the anti-slip strip 225 on the fixing plate 224 increases the friction between the lower clamp 22 and the column 11, further tightening the lower clamp 22 to prevent the lower clamp 22 from separating from the column 11.

[0033] Then, place the pipe between the upper clamp 21 and the lower clamp 22, and fix the upper clamp 21 and the lower clamp 22 together by bolts;

[0034] Next, when the diameter of the pipe is smaller than the upper clamp 21 and the lower clamp 22, the adjusting nut 211 is rotated to push out the pressing block 212 so that the pressing block 212 fits the pipe and clamps the pipe to complete the fixing of the pipe 3.

[0035] Finally, when hot air passes through the pipe 3, the pipe 3 will expand and contract due to heat. The deformation of the convex ring of the rubber ring 23 can alleviate the deformation of the pipe 3 and prevent the lower clamp 22 and the upper clamp 21 from cracking the pipe.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
