[0023] Refer to Figures 1-4 , the steel pipe support safety reinforcement device disclosed in this solution is arranged at the defective part of the steel pipe support to be reinforced, and is used to increase the pipe cross-section at the defective part to enhance the stress performance at the defective part; the steel pipe support safety reinforcement device includes a hoop member 10, an anti-slip member and a reinforcing member. A plurality of hoop members 10 are arranged around the outer wall of the steel pipe support to be reinforced, so that the outer wall of the steel pipe support to be reinforced is closely attached to the inner wall of the hoop member 10; the anti-slip member is arranged on the inner wall of the hoop member 10 and is used to increase the friction force between the outer wall of the steel pipe support to be reinforced and the inner wall of the hoop member 10; it is arranged on the hoop member 10 along the length direction of the hoop member 10 and is used to enhance the stress performance of the hoop member 10 in the length direction.

[0024] Compared with the prior art, the steel pipe support safety reinforcement device of this solution surrounds the defective position of the steel pipe support through a number of hoop members 10, so that the local cross-section of the steel pipe at the weak part increases. The reinforcement device can share the force with the vertical pole, effectively strengthening the weak part of the formwork support and ensuring the safety construction during the formwork pouring process. The anti-slip member increases the friction between the inner wall of the hoop member 10 and the outer wall of the steel pipe support, preventing the hoop member 10 from sliding. The strengthening member increases the rigidity of the hoop member 10 itself, which is beneficial to improving the force-bearing performance of the hoop member 10 in the length direction, avoiding bending, and enhancing the stability of the steel pipe support.

[0025] See Figure 1 , in the first embodiment, flange plates 11 are respectively provided at both ends of each hoop member 10. Screw holes are provided on the flange plates 11, and a number of bolts 12 are fixed after passing through the screw holes of the corresponding flange plates 11, so that a number of hoop members 10 are spliced and formed through the flange plates 11. The two hoop members 10 are detachably connected, which is convenient for the hoop members 10 to be produced into modules with different radii. According to the outer diameter of different steel pipe supports, different hoop members 10 are selected for combination, and the opposite hoop connecting plates are firmly connected together through the connection of bolts 12.

[0026] In another embodiment, the hoop member 10 includes two semi-circular steel plates. One end of the two hoop members 10 is rotatably connected, and the other end of the two hoop members 10 is detachably connected by passing bolts 12 through the flange plates 11. The rotatable connection of the two hoop members 10 facilitates the paired use of the two hoop members 10 and avoids confusion.

[0027] It should be noted that the hoop member 10 is a semi-circular plate member, an arc-shaped plate member or a flat plate member. As long as the hoop member 10 can surround the outer wall of the steel pipe support to enhance the use stability of the steel pipe support, it belongs to the simple deformation and transformation of this solution.

[0028] See Figure 2 , in the second embodiment, the strengthening member is a reinforcing rib 21 provided on the outer wall of the hoop member 10. The reinforcing rib 21 is opened along the length direction of the hoop member 10 and is as long as the hoop member 10. The reinforcing rib 21 and the hoop member 10 can be an integrally formed structure. By locally thickening the hoop member 10 in the length direction, the force-bearing performance of the hoop member 10 in the length direction can be effectively improved, and the use stability of the steel pipe support can be enhanced.

[0029] See Figure 3 , in the third embodiment, the strengthening member is an extended reinforcing plate 22 extending along the length direction of the hoop member 10. The extended reinforcing plate 22 is not wider than the width of the hoop member 10 and is attached to the outer wall of the steel pipe support. The extended reinforcing plate 22 extends in the length direction of the hoop member 10, which is beneficial to being applied to the situation where the defective position of the steel pipe support is relatively long and improving the reinforcement effect of the hoop member 10.

[0030] See Figure 4 In the fourth embodiment, the safety reinforcement device for the steel pipe support further includes a pressing member disposed on the inner wall of the hoop member 10 for pressing between the inner wall of the hoop member 10 and the outer wall of the steel pipe support to be reinforced, so as to reinforce the connection between the hoop member 10 and the steel pipe support.

[0031] Specifically, the pressing member is a wedge-shaped pressing block 31, and a wedge-shaped groove 32 adapted to the wedge-shaped pressing block 31 is provided on the inner wall of the hoop member 10. The wedge-shaped pressing block 31 is inserted into the wedge-shaped groove 32. After the hoop member 10 is surrounded by the outer wall of the steel pipe support, the wedge-shaped pressing block 31 is inserted into the wedge-shaped groove 32, and the connection stability between the hoop member 10 and the steel pipe support is improved by the pressing of the wedge-shaped pressing block 31.

[0032] Preferably, a sandblasting layer 41 or a corrugated band is provided on the inner wall of the hoop member 10 to increase the friction between the inner wall of the hoop member 10 and the outer wall of the steel pipe support to be reinforced. The inner wall roughness is increased to reinforce the connection between the hoop and the steel pipe.

[0033] The application example of this solution is as follows:

[0034] Two semi-circular steel plates with a height of 100 mm and a thickness of 4 m, and both semi-circular steel plates extend 25 mm flange connection plates. The connection plates on both sides are connected by 3 bolts 12. In the above simple hoop structure of the present utility model, considering that the device and the steel pipe vertical pole are likely to slip due to improper construction, sandblasting treatment is performed on the entire height of the inner semi-circle. Medium-coarse sand with a preferred coating thickness of 0.25 mm is used to increase the friction between the reinforced hoop and the steel pipe. The semi-circular steel plates can be produced in modules and replaced at any time. The two semi-circular steel plates are firmly connected together by the bolts 12 connecting the opposite hoop connection plates.

[0035] When the present utility model is specifically implemented, this hoop reinforcement device can be fastened at the weak vertical poles with defects in the process, such as the vertical poles below the bottom horizontal bar and the corner vertical poles, so that the local cross-section of the steel pipe at the weak part increases. The reinforcement device can share the force with the vertical pole, effectively strengthening the weak parts of the formwork support and ensuring the safe construction during the formwork pouring process.

[0036] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model should be subject to the appended claims.
