Both ends of the expanding shaft 5 are in the shape of a three-stage cone. The middle part of the expanding shaft 5 is in the inner expansion tube 2, and the two ends of the expanding shaft 5 respectively pass through the top plate 4 and extend out of the inner expansion tube 2 and are fixed to the inner expansion tube 2 through a clamping nut 6. The outer wall of the expanding shaft 5, the inner wall of the inner expansion tube 2 and the top plate 4 are enclosed to form an annular chamber 7, and a sealing gasket 8 with a U-shaped cross-section is provided and sealed between the inner side surface of the top plate 4 and the first-stage cone of the expanding shaft 5 in the annular chamber 7, and the opening direction of the sealing gasket 8 is toward the center of the inner expansion tube 2. Both ends of the expanding shaft 5 are provided with a T-shaped channel 51. The first end 511 and the second end 512 of the two T-shaped channels 51 are respectively connected to the annular chamber 7. As Figure 3 The third end 513 of one T-shaped channel 51 is connected to the pressure test pump 91 through the liquid inlet pipeline 9, and the third end 513 of the other T-shaped channel 51 is connected to the liquid discharge pipeline 10. The liquid inlet pipeline 9 is provided with a first valve 92, and the liquid discharge pipeline 10 is provided with a second valve 101.

[0044] like Figure 3 , Figure 5 and Figure 6 Each of the reinforcing bracket mechanisms 3 includes two reinforcing bracket fixing seats 31. A retaining spring fixing seat 32 is provided at both ends of the reinforcing bracket fixing seat 31, and a retaining spring 33 is provided on the retaining spring fixing seat 32, and the two reinforcing bracket fixing seats 31 are connected by the retaining spring 33 to form a fixing seat whole 34. The fixing seat whole 34 is sleeved on the annular groove 21 on the inner expansion tube 2. At least one reinforcing bracket 35 is provided on the outer surface of each reinforcing bracket fixing seat 31.

[0045] The reinforcing support 35 is in a mesh shape. The cross section of the reinforcing support fixing seat 31 is in an arc shape.

[0046] Specifically, a pressure gauge 93 is provided on the liquid inlet pipeline 9 between the first valve 92 and the expansion shaft 5 .

[0047] In the first embodiment, the reinforcing bracket 35 is arranged on the outer surface of the reinforcing bracket fixing seat 31 by means of bolts 36 .

[0048] A method for manufacturing the above-mentioned metal curtain wall reinforced composite pipe comprises the following steps:

[0049] 1) First place the curtain wall profile tube 1 on the workbench 11. Figure 8 .

[0050] 2) Then, a plurality of reinforcing bracket mechanisms 3 are sequentially installed on the annular groove 21 on the inner expansion tube 2 .

[0051] 3) Then insert the inner expansion tube 2 with the installed reinforcing bracket mechanism 3 into the curtain wall profile tube 1.

[0052] 4) Start the clamping cylinder 12 to fix the curtain wall profile tube 1.

[0053] 5) Insert the expansion shaft 5 into the inner expansion tube 2, and then install the sealing gasket 8 and the top plate 4 in sequence, and then tighten

[0054] Tighten the compression nut 6 on the outside of the top plate 4.

[0055] 6) Then connect the third end 513 of the T-shaped channel 51 at one end of the expansion shaft 5 to the test

[0056] The third end 513 of the T-shaped channel 51 at the other end is connected to the discharge pipeline 10 .

[0057] 7) Open the first valve 92 on the inlet pipeline 9 and the second valve 101 on the discharge pipeline 10 to start

[0058] The pressure test pump 91 is activated, and the liquid enters the T-shaped channel 51 of the expansion shaft 5 through the first valve 92. When the liquid fills the entire annular chamber 7 and the T-shaped channel 51, the work of removing air is completed.

[0059] 8) After the air is exhausted, close the second valve 101. As the hydraulic pressure in the annular chamber 7 increases, when the hydraulic pressure reaches the elastic deformation of the material at the annular groove 21 on the inner expansion tube 2, due to the principle that the pressure of the liquid in the sealed container is equal everywhere, the annular groove 21 of the inner expansion tube 2 expands outward under the action of the hydraulic pressure. At this time, the reinforcing bracket fixing seat 31 expands outward by opening the retaining spring 33 as the hydraulic pressure increases. When the reinforcing bracket 35 on the reinforcing bracket fixing seat 31 and the inner wall of the curtain wall profile tube 1 reach an interference fit, close the pressure test pump 91 and the first valve 92, stabilize the pressure for 5 minutes, and then open the second valve 101 to release the pressure.

[0060] 9) After the pressure relief is completed, loosen the compression nuts 6 at both ends of the expansion shaft 5, remove the top plates 4 and sealing gaskets 8 at both ends, and then pull the expansion shaft 5 out of the inner expansion tube 2.

[0061] 10) Release the clamping cylinder 12 to complete the production of the metal curtain wall reinforced composite pipe.

[0063] See also Fig. 9 The difference between the second embodiment and the first embodiment is that: in the second embodiment, the inner expansion tube 2 is provided with a plurality of spaced outer sleeves 22, and the annular groove 21 is the gap between two adjacent outer sleeves 22. Fig. 9 .

[0064] Advantages and beneficial effects of the present invention:

[0065] 1. The present invention expands outward through the inner expansion tube, so that a stable interference fit is formed between the reinforcing bracket, the curtain wall profile tube and the inner expansion tube, which greatly improves the strength of the curtain wall profile tube; compared with the dynamic fit between the reinforcing tube and the curtain wall profile tube in the prior art, the present invention has a greater reinforcing effect on the curtain wall profile tube.

[0066] 2. The reinforcing bracket of the present invention is in a mesh shape and is a spatial light steel structure under static load. Each reinforcing bracket is reasonably stressed, has good stability, is light in weight, and has high strength and rigidity.
