[0022] Compared with the prior art, the present application has the following beneficial effects:

[0023] 1. Through the stepped design of the sleeve pipe at both ends, the rubber sealing ring is accurately positioned, when the nut or the wall connecting steel pipe extrudes the first annular extrusion plate, the extrusion rod pushes the second annular extrusion plate, the inclined surface of which converts the axial force into radial expansion force, so that the sealing ring uniformly deforms and tightly fits the hole wall, this kind of dynamic sealing structure can effectively prevent moisture from penetrating into the wall without additional sealing material, avoid the damage of thermal insulation layer due to dampness, solve the leakage problem of traditional wall penetrating piece from the root, and reduce the later maintenance cost.

[0042] Specifically, the end of the tension bolt 1 is provided with a guide slot 45, the inner walls of the first, second and third pads 5, 6 and 47 are fixedly installed with guide blocks 46, the three guide blocks 46 are matched with the guide slot 45. The guide slot 45 and the guide blocks 46 on the first, second and third pads 5, 6 and 47 form a sliding fit, which limits the rotation of the first, second and third pads 5, 6 and 47 along the circumference of the tension bolt 1, ensures that the first, second and third pads 5, 6 and 47 always maintain the correct force posture, and this guide structure makes the pad only move axially during the tightening of the tension nut 13, avoids uneven force caused by deflection, and at the same time ensures the accurate alignment of the expansion mechanism and the sealing ring 7, and ensures the stability of the sealing effect. In addition, the cooperation of the guide slot 45 and the guide block 46 also reduces the alignment difficulty during installation, and improves the construction efficiency.

[0043] Through the above structure, the pull bolt 1 penetrates the sleeve 4 embedded in the wall body, forming the core force bearing connecting the wall body and the scaffold. The sliding property facilitates flexible adjustment of the position during construction. The sealing rings 7 sleeved at both ends of the sleeve 4 provide an initial sealing basis for the wall body reserved hole. The expansion mechanism on the first and second pads 5 and 6 can cooperate with the sealing rings 7 during installation to enhance the sealing effect. The first, second and third pads 5, 6 and 47 are slidingly installed on the pull bolt 1 and can be adjusted according to the actual situation of the wall body on both sides to ensure close fit with the wall body or wall connecting pipe 2, realizing effective force transmission. The four legs 17 on the first pad 5 are slidingly arranged through the mounting holes and can be flexibly extended under the action of the adjusting assembly to adapt to the support requirements of different wall structures and enhance the stability of the device and the wall connection. The wall connecting pipe 2 is sleeved around the pull bolt 1 and one end is in close contact with the first pad 5, transmitting the load of the scaffold to the first pad 5 and then to the wall body.

[0044] As shown in Figure 2 and Figure 3 , both ends of the sleeve 4 are step-shaped, and two sealing rings 7 are sleeved at the stepped connection of both ends.

[0045] Through the above structure, the step-shaped design of both ends of the sleeve 4 provides a precise installation positioning reference for the sealing ring 7, avoiding axial displacement of the sealing ring 7 under stress. When the second annular extrusion plate 12 extrudes the sealing ring 7, the stepped structure can limit the deformation direction of the sealing ring 7, ensuring uniform radial expansion, so as to form a tightly fitted sealing surface with the hole wall of the wall body reserved hole, significantly improving the waterproof performance.

[0047] Through the above structure, when the axial pressure is applied to the pair of pull nuts 13 or the wall connecting steel pipe 2 matched with the second gasket plate 6, the first annular extrusion plate 10 on the second gasket plate 6 or the first gasket plate 5 can be extruded respectively, the extrusion rod 9 is pushed to slide along the extrusion hole through the first annular extrusion plate 10, the second annular extrusion plate 12 is driven to move synchronously, the slope design of the second annular extrusion plate 12 converts the axial force into the radial expansion force, the sealing ring 7 is uniformly deformed and tightly fitted with the hole wall, the dynamic sealing is realized, and the extrusion rod 9 and the annular extrusion plate can be reset by the first reset spring 11 when the pressure is removed, so that the device is convenient to disassemble and reuse, the sealing function is automatically realized during installation, no additional sealing material is needed, and the construction cost and operation complexity are reduced.

The threaded connection of the convex cylinder 15 and the sleeve 14 constitutes a screw drive mechanism, and the extension length of the support leg 17 can be accurately controlled by rotating the convex cylinder 15, so as to adapt to different thicknesses of the concrete protective layer 42 and the thermal insulation layer 43. The connecting plate 16 links the four support legs 17 to ensure that they are synchronized in extension and contraction, so that the support force of the support leg 17 is evenly distributed on the wall body, preventing local overloading of the wall body. Specifically, the end of the support leg 17 is provided with anti-skid serrations 18, which can enhance the friction between the support leg 17 and the reinforced concrete wall 44, prevent slipping during pressure transmission, and further ensure the stability of the structure.
