For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] As attached Figure 1 The spherical annular water stop 10 involved in this embodiment is shown, and the outer diameter R of the spherical end 11 is 13 cm. In this embodiment, the first component is a cast drainage open channel 20, and the second component is a connecting well 30. Figure 2 As shown, the cross-section of the connecting shaft 30 is "U"-shaped, with a height of 6.7m, a width of 7.2m, a wall thickness of 0.6m on both sides, and a bottom plate thickness of 0.5m. A spherical annular waterstop 10 is set at the midline of its cross-sectional shape; the spherical annular waterstop 10 is fixed to the steel bars and the formwork in advance, and is poured into the concrete when the concrete is poured.

[0035] When the connecting well 30 of this embodiment is cast, the construction gap with the open drainage channel 20 is 5 cm, and the outer diameter of the exposed spherical end 11 of the spherical annular waterstop 10 is 13 cm, so it is necessary to pre-compress the spherical annular waterstop in advance.

[0036] This embodiment provides a spherical annular water stop pre-compression device, such as Figure 3-Figure 4 As shown, two pre-compression devices are symmetrically arranged on one side of the spherical annular water stop 10 away from the open drainage channel 20, including:

[0037] The pre-pressing assembly 40 includes a pre-pressing member 41 and an auxiliary pre-pressing member 42. The pre-pressing member 41 is arranged on one side of the spherical end 11 of the spherical annular waterstop 10 and extends downward along the length direction of the spherical annular waterstop 10; the auxiliary pre-pressing member 42 is arranged parallel to the pre-pressing member 41 and spaced apart, and a side surface of the pre-pressing member 41 in contact with the spherical end 11 is coplanar with one side surface of the auxiliary pre-pressing member 42, such as Figure 4 As shown; in this embodiment, the pre-pressed member 41 is 8# channel steel, whose waist plate is pressed on the spherical end 11, and the auxiliary pre-pressed member 42 is 5# channel steel, whose waist plate is perpendicular to the waist plate of the pre-pressed member 41, that is, the waist plate of the pre-pressed member 41 and a wing plate of the auxiliary pre-pressed member 42 are coplanar,

[0038] One end of the connecting member 50 is fixedly disposed in the gap between the pre-pressing member 41 and the auxiliary pre-pressing member 42. The connecting member 50 is perpendicular to the pre-pressing member 41, that is, the connecting member 50 extends in the horizontal direction. In this embodiment, the connecting member 50 is also a 5# channel steel.

[0039] A fixing assembly 60 is arranged at the other end of the connecting member 50 and is arranged in parallel with the pre-pressing assembly 40. A second gap 61 is formed in the middle of the fixing assembly 60.

[0040] The adjusting assembly 70 is arranged in parallel with the connecting member 50, and includes an adjusting rod 71 and an adjusting bolt 72. The first end 711 of the adjusting rod 71 is fixed to the outer surface of the open drainage channel 20, and the second end 712 passes through the gap between the pre-pressing member 41 and the auxiliary pre-pressing member 42 and the second gap 61 in the middle of the fixing assembly 60 in sequence. The end of the second end 712 is provided with the adjusting bolt 72;

[0041] By rotating the adjusting bolt 72 , the prestressing assembly 40 , the connecting piece 50 , and the fixing assembly 60 move synchronously along the adjusting rod 71 toward the open drainage channel 20 , and the prestressing piece 41 of the prestressing assembly 40 compresses the spherical end 11 of the spherical annular waterstop 10 .

[0042] In this technical solution, the pre-compression device can realize the pre-compression of the spherical annular waterstop, which solves the problem that the waterstop between two connected cast-in-place components cannot be compressed. It has a simple structure, effectively improves construction efficiency, reduces construction cost investment, and ensures project quality.

[0043] like Figure 4As shown, the adjustment component 70 also includes a mounting plate 73, which has a mounting hole (not shown in the figure). The second end 712 of the adjustment rod 71 passes through the mounting hole to fix the mounting plate 73 between the fixing component 60 and the adjusting bolt 72. The adjusting bolt 72 is rotated, and the mounting plate 73 moves toward the direction of the open drainage channel 20, pushing the pre-stressing component 40, the connecting member 50, and the fixing component 60 to move synchronously as a whole. The pre-stressing member 41 compresses the spherical end 11. In this embodiment, the width of the compressed spherical end 11 is 5 cm, which meets the construction requirements.

[0044] Specifically, the first end 711 of the adjustment rod 71 is fixed to the open drainage channel 20 by means of a stainless steel expansion bolt.

[0045] Continue to see Figure 4 The fixing assembly 60 includes fixing members 62 symmetrically arranged on both sides of the other end of the connecting member 50, and a second gap 61 is provided between the two fixing members 62. The fixing members 62 are parallel to the auxiliary preloading member 42. In this embodiment, the fixing members 62 are also 5# channel steels. The two fixing members 62 are mirror-imaged, and their waist plates are parallel to the waist plates of the auxiliary preloading member 41. One fixing member 62 is symmetrically arranged with the auxiliary preloading member 41 on the same side at both ends of the connecting member 50, and the other fixing member 62 is arranged with the preloading member 41 on the same side at the other side of both ends of the connecting member 50.

[0046] In order to provide stable support for the pre-pressing assembly 40 and the fixing assembly 60, in this embodiment, two connecting members 50 are provided, which are evenly distributed along the length direction of the pre-pressing member 41. At the same time, the gap between the pre-pressing member 41 and the auxiliary pre-pressing member 42, the second gap 61 between the two fixing members 62, and the diameter of the adjusting rod 71 are adapted to each other, so that the adjusting rod can smoothly pass through the gap and the second gap 61, and the mounting plate 73 can be stably fixed between the fixing members 61.

[0047] When the spherical annular waterstop 10 is compressed, only the adjustment component 70 is removed from the entire pre-compression device, and the rest are not removed. The other components are cast together with the spherical annular waterstop 10 in the connecting well 30. When using the pre-compression device, the surface needs to be anti-corrosive in advance.

[0048] Based on the above technical solution, the pre-compression device can realize the pre-compression of the spherical annular waterstop, which solves the problem that the waterstop between two connected cast-in-place components cannot be compressed. It has a simple structure, effectively improves the construction efficiency, and ensures the quality of the project.

[0049] Using common materials such as channel steel and adjusting rods can meet the engineering requirements without investing too much cost.

[0050] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0051] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
