Description

Technical Field

[0001] This utility model relates to the field of pipe gallery waterstop protection technology, specifically to a pipe gallery roof expansion joint waterstop installation device. Background Technology

[0002] Cast-in-place box culverts (integrated utility tunnels), as vital arteries of urban underground infrastructure, suffer from a common quality problem at their expansion joints, particularly regarding the waterproofing of the tunnel's top and bottom slabs. Chinese patent application number 202110821757.7 discloses a protective device and construction method for an externally attached waterstop at the expansion joint of the tunnel's bottom slab. This device includes an externally attached waterstop and a cover plate. The cover plate comprises a horizontal plate and lower protrusions, with the lower protrusions spaced apart on the lower surface of the horizontal plate. The externally attached waterstop is inserted into the gaps between the lower protrusions. After the waterproofing protective layer of the cast-in-place integrated utility tunnel is completed and reaches the design strength and curing age, the externally attached rubber waterstop is laid at the expansion joint location. Then, the foundation slab reinforcement and shear reinforcement are tied, and the embedded rubber waterstop is clamped and fixed using U-shaped reinforcement before pouring the concrete bottom slab on one side of the expansion joint. After reaching the design strength and curing age, the end formwork of the expansion joint is removed. The external rubber waterstop of this protective device is laid under the reinforcement of the concrete base slab. However, for the external rubber waterstop on the pipe gallery roof slab, due to the lack of support, it is generally pre-fixed to the foundation reinforcement of the pipe gallery roof slab by binding and welding. This makes it susceptible to deformation of the foundation reinforcement, causing it to shift during concrete pouring and solidification, thus affecting the waterstop effect. The embedded rubber waterstop on the pipe gallery base slab is fixed to the foundation reinforcement of the pipe gallery base slab before pouring. The embedded rubber waterstop on the pipe gallery roof slab is generally the same, also fixed to the foundation reinforcement of the pipe gallery roof slab before pouring. Similarly, it is susceptible to deformation of the foundation reinforcement, causing it to shift during concrete pouring, thus affecting the waterstop effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an installation device for the expansion joint waterstop of the pipe gallery roof slab that improves installation stability and subsequent water-stopping effect.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An installation device for a waterstop at a deformation joint in a pipe gallery roof includes a side support frame, an upper template, a lower template, an externally attached waterstop, and a centrally embedded waterstop. The upper and lower templates are located on the same side of the side support frame, and the upper and lower templates are spaced vertically to form a socket interval. Half of the centrally embedded waterstop is inserted into the socket interval, and the other half protrudes to the outside of the upper and lower templates. The side support frame has a socket above the upper template, and half of the externally attached waterstop is inserted into the socket, while the other half protrudes to the outside of the upper and lower templates.

[0005] As a further improvement to the above technical solution: The socket is provided with multiple supporting steel bars placed below the external waterstop. Each of the supporting steel bars is arranged at intervals along the length of the upper template and extends outward from the outer side of the upper and lower templates. The external waterstop is supported on each of the supporting steel bars.

[0006] The length of the supporting steel bar extending outward is longer than the length of the externally attached waterstop extending outward.

[0007] The inner end of the socket is provided with a limiting part, which is located above the inner end of the supporting steel bar.

[0008] Each of the supporting steel bars is supported by a longitudinal positioning bar, and the external waterstop is supported on the longitudinal positioning bar.

[0009] Both the upper and lower templates are detachably connected to the side support frame.

[0010] The side support frame has an upper through-hole and a lower through-hole on both sides. The upper template and the lower template have an upper insert block and a lower insert block on the side facing the side support frame, respectively. The upper insert block is inserted into the upper through-hole, and the lower insert block is inserted into the lower through-hole. An upper limit block is pressed at the port of the upper through-hole away from the upper insert block, and a lower limit block is pressed at the port of the lower through-hole away from the lower insert block. The upper limit block and the upper insert block, and the lower limit block and the lower insert block are respectively connected by fixing screws.

[0011] Both the upper and lower through openings extend along the length of the side support frame.

[0012] The lower end of the upper template is bent into the socket gap to form an upper wall panel, which is in close contact with the upper side wall of the socket gap. The upper end of the lower template is bent into the socket gap to form a lower wall panel, which is in close contact with the lower side wall of the socket gap. The embedded waterstop is clamped between the upper wall panel and the lower wall panel.

[0013] The side support frame includes a side frame and multiple side supports. Each side support is fixed to the end side of the section to be poured on the top slab of the pipe gallery and is arranged side by side. The side frame is fixed on the side of each side support facing the section to be poured on the top slab of the pipe gallery. The upper template and lower template are located on the side of the side frame facing the section to be poured on the top slab of the pipe gallery. The socket interval and socket slot are both located on the side frame. The outer side of the upper template and lower template faces the section to be poured on the top slab of the pipe gallery.

[0014] Compared with the prior art, the advantages of this utility model are: The usage process of the utility model's pipe gallery roof expansion joint waterstop installation device is as follows: The side support frame is fixed to the end side of the pipe gallery roof section to be poured (e.g., fixed to the formwork device below the pipe gallery roof section). The upper and lower formwork are located on the side of the side support frame facing the pipe gallery roof section to be poured, serving as the end side formwork for the pipe gallery roof section to be poured. The embedded waterstop and the external waterstop extend into the pipe gallery roof section to be poured. Then, concrete is poured into the pipe gallery roof section to be poured. After the poured concrete reaches the required solidification, the side support frame, upper formwork, and lower formwork are removed, leaving only the external waterstop and the embedded waterstop. Because both the external waterstop and the embedded waterstop are installed on the side support frame 1, rather than on the foundation reinforcement of the pipe gallery roof section, the influence of foundation reinforcement deformation during concrete pouring and solidification is reduced, improving installation stability and subsequent waterstop effect.

[0023] Figures 1 to 4 This invention illustrates an embodiment of the pipe gallery roof expansion joint waterstop installation device. The pipe gallery roof expansion joint waterstop installation device of this embodiment includes a side support frame 1, an upper template 2, a lower template 3, an external waterstop 4, and a centrally embedded waterstop 5. The upper template 2 and the lower template 3 are located on the same side of the side support frame 1, and the upper template 2 and the lower template 3 are spaced vertically to form a socket interval 6. Half of the centrally embedded waterstop 5 is inserted into the socket interval 6, and the other half is suspended outside the upper template 2 and the lower template 3. The side support frame 1 is provided with a socket 7 above the upper template 2. Half of the external waterstop 4 is inserted into the socket 7, and the other half is suspended outside the upper template 2 and the lower template 3.

[0024] The process of using this pipe gallery roof expansion joint waterstop installation device is as follows: Fix the side support frame 1 to the end side of the pipe gallery roof section 101 to be poured (e.g., fix it to the formwork device below the pipe gallery roof section 101 to be poured). The upper formwork 2 and lower formwork 3 are located on the side of the side support frame 1 facing the pipe gallery roof section 101 to be poured, serving as the end side formwork of the pipe gallery roof section 101 to be poured. The embedded waterstop 5 and the external waterstop 4 are suspended into the pipe gallery roof section 101 to be poured. Then, pour concrete into the pipe gallery roof section 101 to be poured. After the poured concrete reaches the solidification requirements, remove the side support frame 1, upper formwork 2 and lower formwork 3, leaving the external waterstop 4 and the embedded waterstop 5. Since both the external waterstop 4 and the embedded waterstop 5 are installed on the side support frame 1 instead of on the foundation steel bars of the pipe gallery top slab, the influence of the deformation of the foundation steel bars during the concrete pouring and solidification process is reduced, which improves the installation stability and subsequent water-stopping effect.

[0025] Furthermore, in this embodiment, multiple supporting steel bars 71 are placed below the external waterstop 4 in the socket 7. These supporting steel bars 71 are spaced apart along the length of the upper template 2 and extend outwards from the outer sides of both the upper and lower templates 3. The external waterstop 4 is supported by these supporting steel bars 71. The supporting steel bars 71 form a support below the external waterstop 4, which helps prevent deformation of the external waterstop 4 and further improves installation stability. The number of supporting steel bars 71 is determined according to actual needs.

[0026] Furthermore, in this embodiment, the length of the supporting steel bar 71 extending outward is longer than the length of the external waterstop 4 extending outward. This ensures that the extended portion of the external waterstop 4 is located on the supporting steel bar 71, further improving installation stability.

[0027] Furthermore, such as Figure 2 As shown, in this embodiment, the inner end of the socket 7 is provided with a limiting part 72, which is located above the inner end of the supporting steel bar 71. That is, the inner end of the supporting steel bar 71 abuts against the lower surface of the limiting part 72, which helps to prevent the protruding end of the supporting steel bar 71 from tilting down and affecting the installation stability of the external waterstop 4.

[0028] Furthermore, in this embodiment, each supporting steel bar 71 is supported by a longitudinal positioning bar 73, and the external waterstop 4 is supported on the longitudinal positioning bar 73. Since the lower side of the external waterstop 4 has a groove, the longitudinal positioning bar 73 can form a support within the groove, improving the support effect.

[0029] Furthermore, in this embodiment, both the upper template 2 and the lower template 3 are detachably connected to the side support frame 1. Thus, during demolding, the connection between the side support frame 1 and the upper template 2 and lower template 3 can be removed first, followed by the removal of the side support frame 1, and then the removal of the upper template 2 and lower template 3. This separate disassembly improves the convenience and efficiency of demolding.

[0030] Furthermore, such as Figure 1 As shown in this embodiment, the side support frame 1 has an upper through-hole 8 and a lower through-hole 9 extending through both sides. The upper template 2 and the lower template 3 have an upper insert block 21 and a lower insert block 31 respectively on the side facing the side support frame 1. The upper insert block 21 is inserted into the upper through-hole 8, and the lower insert block 31 is inserted into the lower through-hole 9. An upper limit block 81 is pressed at the end of the upper through-hole 8 away from the upper insert block 21, and a lower limit block 91 is pressed at the end of the lower through-hole 9 away from the lower insert block 31. The upper limit block 81 is connected to the upper insert block 21, and the lower limit block 91 is connected to the lower insert block 31, respectively, by fixing screws 10. In other words, the upper template 2 is detachably fixed to the side support frame 1 by the upper limit block 81 and fixing screws 10, and the lower template 3 is detachably fixed to the side support frame 1 by the lower limit block 91 and fixing screws 10, making assembly and disassembly very convenient. Preferably, the upper insert block 21 is adapted to the upper through-hole 8, and the lower insert block 31 is adapted to the lower through-hole 9. In this way, the upper through-hole 8 supports the upper template 2 through the upper insert block 21, and the lower through-hole 9 supports the lower template 3 through the lower insert block 31, thereby improving the installation stability.

[0031] Furthermore, in this embodiment, both the upper through-hole 8 and the lower through-hole 9 extend along the length direction of the side support 1. Of course, in other embodiments, multiple upper through-holes 8 and lower through-holes 9 can be provided, spaced apart along the length direction of the side support 1. The length direction of the side support 1 is the same as the length direction of the upper template 2 and the lower template 3, such as... Figure 4 The up and down directions are shown.

[0032] Furthermore, such as Figure 1 As shown, in this embodiment, the lower end of the upper template 2 is bent inward into the socket gap 6 to form an upper wall panel 22, which is tightly attached to the upper side wall of the socket gap 6. The upper end of the lower template 3 is bent inward into the socket gap 6 to form a lower wall panel 32, which is tightly attached to the lower side wall of the socket gap 6. The embedded waterstop 5 is clamped between the upper wall panel 22 and the lower wall panel 32. On the one hand, the setting of the upper wall panel 22 and the lower wall panel 32 helps to improve the stability of the installation of the upper template 2 and the lower template 3. On the other hand, it improves the sealing between the upper template 2 and the lower template 3, which helps to prevent grout leakage.

[0033] Furthermore, in this embodiment, the side support frame 1 includes a side frame 11 and multiple side supports 12. Each side support 12 is fixed to the end side of the section 101 to be poured on the top plate of the pipe gallery and is arranged side by side (specifically, side by side along the length direction of the upper template 2 and the lower template 3). The side frame 11 is fixed on the side of each side support 12 facing the section 101 to be poured on the top plate of the pipe gallery. The upper template 2 and the lower template 3 are located on the side of the side frame 11 facing the section 101 to be poured on the top plate of the pipe gallery. The socket interval 6 and the socket slot 7 are both located on the side frame 11. The outer sides of the upper template 2 and the lower template 3 are on the side facing the section 101 to be poured on the top plate of the pipe gallery. The upper limit block 81 and the upper template 2 are clamped to both sides of the side support 12 under the tightening action of the corresponding fixing screws 10. The lower limit block 91 and the lower template 3 are clamped to both sides of the side support 12 under the tightening action of the corresponding fixing screws 10. Preferably, the side frame 11 and multiple side supports 12 can be fixed to the formwork device below the section 101 to be poured on the top plate of the pipe gallery by fixing bolts.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
