Description

Technical Field

[0001] This utility model relates to the technical field of embedded waterstop fixing structure, specifically to an embedded waterstop installation device. Background Technology

[0002] During the construction of the tunnel invert, to ensure the waterproofing requirements of the longitudinal construction joints, a waterstop structure needs to be installed during the invert pouring process. In actual installation, the embedded waterstop is usually supported by the invert formwork structure to facilitate the invert pouring and shaping. To ensure the waterstop's effectiveness, it needs to be fixed at half the thickness of the invert, and the waterstop must be kept straight during pouring to avoid wrinkles or bends.

[0003] Existing invert arch formwork mainly consists of an upper formwork, a lower formwork, and connecting components. During use, a waterstop is fixed between the upper and lower formwork, which then compress and fix the waterstop. While this type of formwork can install and fix the waterstop, in practical applications, the waterstop cannot be adjusted before being pressed and fixed by the upper and lower formwork, especially along its width. This results in poor installation and fixing of the waterstop. Furthermore, after fixing the waterstop, the connection between the upper and lower formwork in existing invert arch formwork is not very stable, potentially affecting the casting quality of the invert arch. Utility Model Content

[0004] The present invention aims to provide an embedded waterstop installation device to solve the problem of poor installation accuracy of waterstops in the prior art.

[0005] To solve the above problems, the present invention adopts the following technical solution: a centrally embedded waterstop installation device, including an upper template and a lower template, both the upper template and the lower template are provided with an L-shaped horizontal section and a vertical section, a fixing gap for fixing the waterstop is provided between the horizontal section of the upper template and the horizontal section of the lower template, and an end fixing mechanism is connected between the end of the horizontal section of the upper template and the end of the horizontal section of the lower template.

[0006] It also includes a U-shaped slide block, with the horizontal sections of both the upper and lower templates located within the U-shape of the slide block. The slide block is slidably connected to the horizontal section of the lower template, and a driving mechanism for driving the slide block to slide is provided on the horizontal section of the lower template. The end of the slide block near the opening is provided with a sliding fixing mechanism facing the horizontal section of the upper template. A waterstop preload adjustment mechanism is slidably connected to the slide block, and a clearance groove that cooperates with the waterstop preload adjustment mechanism is provided on the horizontal section of the upper template.

[0007] The principles and beneficial effects of this application are as follows:

[0008] In this application, when installing the upper and lower formwork, the horizontal section of the upper formwork is located above the horizontal section of the lower formwork. The embedded waterstop in the prior art is installed in the fixed gap between the horizontal sections of the upper and lower formwork. In addition, the lower formwork is fixedly connected to other formwork frames of the invert arch in the prior art, and the ends of the horizontal sections of the upper and lower formwork are connected by an end fixing mechanism. Thus, after the lower formwork is fixed, the upper formwork can be fixed by the end fixing mechanism to ensure the stability of the upper and lower formwork structures during the invert arch pouring process.

[0009] In this application, a U-shaped sliding block is slidably connected to the horizontal section of the lower template. During the sliding process, both the horizontal sections of the upper and lower templates are located within the U-shape of the sliding block. A sliding fixing mechanism is provided at the end of the sliding block near the opening, facing the horizontal section of the upper template. When the sliding block slides to a suitable position relative to the horizontal section of the lower template, the sliding fixing mechanism slides towards the horizontal section of the upper template, ultimately contacting and pressing against it. This presses and fixes the horizontal section of the upper template onto the horizontal section of the lower template (and also presses and fixes the waterstop within the fixing gap). Combining the end fixing mechanism and the sliding fixing mechanism in this application, when the horizontal sections of the upper and lower templates are connected and fixed, the connection and fixation occur not only at the ends of the horizontal sections but also at the middle, effectively improving the stability of the upper and lower templates. In particular, the installation of the upper template is more stable, effectively ensuring the quality of the invert arch casting.

[0010] In addition, this application includes a waterstop pre-compression adjustment mechanism slidably connected to the slide block. This mechanism is used to pre-compress the waterstop onto the slide block. Therefore, by adopting the technical solution of this application, during the actual installation of the waterstop, the lower template is first installed and fixed. Then, the waterstop pre-compression adjustment mechanism is used to squeeze and fix the waterstop onto the slide block. The slide block is then driven to slide relative to the horizontal section of the lower template. Since the waterstop is pre-compressed and fixed by the waterstop pre-compression adjustment mechanism, the slide block can pull the waterstop along with it when it slides. This allows for a small range of adjustment of the waterstop's position, enabling more precise installation and fixing. Once the waterstop's position is adjusted to the predetermined position, the waterstop pre-compression adjustment mechanism can always pre-compress and fix the waterstop. Subsequently, when the upper template is installed on the lower template, it can effectively prevent changes in the waterstop's position that could cause installation deviations. It also makes the subsequent operation of fixing the waterstop onto the upper template more convenient and efficient.

[0011] Preferably, as an improvement, the driving mechanism includes a driving seat and a driving screw. The driving seat is fixedly connected to the horizontal and vertical sections of the lower template, the driving screw is rotatably connected to the driving seat, and the slide is provided with a threaded hole that is threadedly engaged with the driving screw.

[0012] In this design, the drive seat is fixedly connected to the horizontal section of the lower template, and one end of the drive screw is rotatably connected to the drive seat. The external thread of the drive screw is threadedly engaged with the threaded hole on the slide. When it is necessary to adjust the position of the slide on the horizontal section of the lower template, simply use external force to rotate the drive screw to drive the slide to slide. After the slide slides to any position, the threaded engagement between the drive screw and the threaded hole can automatically prevent the slide from moving arbitrarily, ensuring that the waterstop position can be maintained at the pre-pressure adjustment position after the waterstop pre-pressure adjustment mechanism is used, thus ensuring the accuracy of the waterstop installation.

[0013] Preferably, as an improvement, the drive seat is provided with a sliding protrusion, and the slide is provided with a sliding groove that slides in cooperation with the sliding protrusion.

[0014] In this design, a sliding protrusion is provided on the drive seat, and a sliding groove is provided on the slide block. By relying on the sliding protrusion, the sliding groove, and the sliding cooperation, the slide block can slide smoothly and accurately relative to the horizontal and vertical sections of the lower template. The structure is simple and the operation is stable. Compared with setting the sliding groove on the drive seat, setting the sliding groove on the slide block in this design can effectively reduce the weight of the slide block, making the sliding adjustment of the slide block more labor-saving.

[0015] Preferably, as an improvement, an anti-detachment block is fixedly connected to the slide block and positioned opposite the drive seat.

[0016] In this solution, the anti-detachment block and the limiting cooperation of the drive seat are used to prevent the slide from slipping off the drive seat during the sliding process of the slide relative to the horizontal section of the lower template, thereby improving the structural stability.

[0017] Preferably, as an improvement, the sliding fixing mechanism includes a locking screw, and the slide seat is provided with a locking screw hole that is threadedly engaged with the locking screw; the waterstop preload adjustment mechanism includes an adjusting screw, and the slide seat is provided with an adjusting screw hole and a pressing part that are threadedly engaged with the adjusting screw, and the horizontal section of the lower template is provided with a pressing groove that is slidably engaged with the pressing part.

[0018] In this design, the screw and threaded hole work together, allowing the screw to be rotated to move closer to or further away from the object being compressed, facilitating compression, fixing, or release. The locking screw in this design can compress and fix the horizontal section of the lower template when rotated, thus fixing the horizontal sections of the upper and lower templates. Furthermore, this design includes an adjusting screw hole and a clamping part on the slide. When the adjusting screw rotates relative to the adjusting screw hole on the slide, the end of the adjusting screw can approach the clamping part on the slide, clamping and fixing the waterstop, achieving pre-compression fixing of the waterstop.

[0019] Preferably, as an improvement, a pressure plate is provided at one end of the adjusting screw near the horizontal section of the lower template. The pressure plate is rotatably connected to the adjusting screw and slidably connected to the slide block.

[0020] In this design, a pressure plate is installed at the end of the adjusting screw near the horizontal section of the lower template. When the adjusting screw rotates relative to the adjusting screw hole, causing the end of the adjusting screw with the pressure plate to approach the horizontal section of the lower template, the pressure plate contacts and abuts against the waterstop. Since the adjusting screw and the pressure plate are rotatably connected, the pressure plate will not rotate with the adjusting screw after it abuts against the waterstop, thus avoiding the pressure plate rotating relative to the waterstop and causing wear on the waterstop.

[0021] Preferably, as an improvement, an auxiliary support rod is rotatably connected to the vertical section of the upper template.

[0022] In this solution, auxiliary support rods are used to provide auxiliary support for the vertical section of the upper formwork, so that the upper formwork can be more stably connected to the lower formwork and the formwork of the invert arch in the existing technology, thereby reducing the occurrence of grout leakage and formwork bursting during the invert arch pouring process.

[0023] Preferably, as an improvement, the end fixing mechanism includes a threaded end screw and an end screw hole, the upper template has a mating hole on the horizontal section that mates with the end screw, and the end screw hole is located on the horizontal section of the lower template.

[0024] In this solution, by using end screws to lock into the end screw holes, the ends of the horizontal and vertical sections of the upper template and the lower template can be easily and stably fixed, and the installation and fixing of the upper template can be completed quickly.

[0025] Preferably, as an improvement, the upper template includes several upper sub-templates arranged side by side, and adjacent upper sub-templates are detachably connected; the lower template includes several lower sub-templates arranged side by side, and adjacent lower sub-templates are detachably connected.

[0026] In this solution, the upper template is divided into multiple upper sub-templates, and the lower template is divided into multiple lower sub-templates. The number of upper and lower sub-templates can be set to be equal and correspond one-to-one. When installing the upper and lower sub-templates, the smaller and lighter upper and lower sub-templates can be installed sequentially, reducing the installation difficulty. At the same time, when installing and fixing multiple upper and lower sub-templates sequentially, the waterstop can be gradually installed and fixed along the length of the waterstop, which facilitates local adjustment or modification of the waterstop during the installation process, making the installation of the waterstop more precise.

[0027] Preferably, as an improvement, the number of slides is multiple, and the slides are provided at the connection positions of adjacent lower templates, and the drive seat is simultaneously connected to the horizontal and vertical sections of two adjacent lower templates.

[0028] In this scheme, multiple sliding blocks are set up, which can adjust and pre-compress multiple points of the waterstop, so that the waterstop can be installed and fixed more accurately. In addition, the drive blocks are connected between the horizontal and vertical sections of two adjacent lower templates. The drive blocks can not only guide the sliding blocks, but also fix the two adjacent lower templates, so that the lower templates are stably connected. Attached Figure Description

[0034] The following detailed description illustrates the specific implementation method:

[0035] The reference numerals in the accompanying drawings of the instruction manual include: upper dividing template 1, upper horizontal section 101, clearance groove 1011, upper vertical section 102, lower dividing template 2, lower horizontal section 201, clamping groove 2011, lower vertical section 202, slide 3, drive seat 4, drive screw 5, sliding protrusion 6, anti-detachment block 7, locking screw 8, adjusting screw 9, clamping seat 10, pressure plate 11, end screw 12, pad 13, auxiliary support rod 14, and waterstop 1000.

[0036] Example 1

[0037] This embodiment is as shown in the appendix. Figure 1 As shown: A type of embedded waterstop installation device includes an upper template and a lower template. To facilitate the processing and installation of the upper and lower templates, [the following is combined with...] Figure 2In this embodiment, the upper template consists of multiple upper sub-templates 1 connected sequentially, and the lower template consists of multiple lower sub-templates 2 connected sequentially. The number of upper sub-templates 1 and lower sub-templates 2 is equal and they are set in a one-to-one correspondence. Of course, in other embodiments besides this one, the number of upper sub-templates 1 and lower sub-templates 2 can be different. For example, only one lower sub-template 2 can be set (i.e., the lower template is a single integrated structure), while the number of upper sub-templates 1 can be multiple. Alternatively, both upper sub-templates 1 and lower sub-templates 2 can be multiple, but the number of lower sub-templates 2 is less than the number of upper sub-templates 1, allowing for faster installation of the lower sub-templates 2. Further examples are not provided here. Figure 1 and Figure 2 Both the upper template 1 and the lower template 2 are provided with horizontal and vertical sections connected in an L-shape. For easy distinction, the upper template 1 has an upper horizontal section 101 and an upper vertical section 102, while the lower template 2 has a lower horizontal section 201 and a lower vertical section 202. The upper horizontal section 101 and the lower horizontal section 201 form a fixed gap for installing and fixing the waterstop 1000.

[0038] Combination Figure 2 , Figure 3 and Figure 4 This embodiment also includes a U-shaped slide block 3. The upper horizontal section 101 and the lower horizontal section 201 are both located within the U-shape of the slide block 3. The slide block 3 is slidably connected to the lower horizontal section 201 along a direction perpendicular to the lower vertical section. The bottom surface of the lower horizontal section 201 is provided with a driving mechanism for driving the slide block 3 to slide. The driving mechanism includes a driving seat 4 and a driving screw 5. The driving seat 4 is fixedly connected to the bottom surface of the lower horizontal section 201 by screws. The driving screw 5 is arranged along a sliding direction parallel to the slide block 3. One end of the driving screw 5 is rotatably connected to the driving seat 4 by a bearing. A threaded hole is opened on the part of the slide block 3 located at the bottom of the lower horizontal section 201. The driving screw 5 is threadedly engaged with the threaded hole. The other end of the driving screw 5 extends beyond the end of the lower horizontal section 201 so that the slide block 3 can be slid by manually rotating the driving screw 5. In addition, to make the slide block 3 slide more smoothly and accurately, in this embodiment, sliding protrusions 6 are integrally formed on both sides of the drive seat 4, and the slide block 3 has a sliding groove that slides with the sliding protrusions 6. The sliding engagement between the sliding protrusions 6 and the sliding groove provides guidance for the sliding of the slide block 3. In this embodiment, to simplify the structure and facilitate installation, a sliding gap is formed between the sliding protrusions 6 and the bottom surface of the lower horizontal section 201 for the slide block 3 to slide. At the same time, an anti-detachment block 7 is fixedly connected to the end of the slide block 3 near the lower vertical section 202 by screws. The anti-detachment block 7 is set opposite to the drive seat 4 and a sliding gap is provided between the anti-detachment block 7 and the drive seat 4 for the slide block 3 to slide. The anti-detachment block 7 controls the sliding stroke of the slide block 3 and prevents the slide block 3 from sliding out of the lower horizontal section 201.

[0039] Combination Figure 1 and Figure 2 The slide block 3 has a sliding fixing mechanism at its end near the opening, facing the upper horizontal section 101. A pre-pressure adjustment mechanism for the waterstop is slidably connected to the slide block 3, and a clamping part on the slide block 3 that directly engages with the pre-pressure adjustment mechanism. Specifically, the sliding fixing mechanism includes a locking screw 8 perpendicular to the lower horizontal section 201. The slide block 3 has a locking screw hole that threadedly engages with the locking screw 8. When the locking screw 8 rotates, it moves downwards towards the upper horizontal section 101 and clamps against it, thus pressing and fixing the upper dividing template 1 onto the lower dividing template 2. Figure 4 The preload adjustment mechanism for the waterstop includes an adjusting screw 9 perpendicular to the lower horizontal section 201. The slide 3 has a clamping part that mates with the adjusting screw 9 and an adjusting screw hole that rotatably engages with the adjusting screw 9. The clamping part is an integrally formed clamping seat 10 on the slide 3, facing the U-shaped interior of the slide 3. The clamping seat 10 is flush with the top surface of the lower horizontal section 201. To facilitate sliding engagement between the clamping seat 10 and the lower horizontal section 201, a clamping groove 2011 is provided on the lower horizontal section 201 to slide with the clamping seat 10. When the adjusting screw 9 rotates relative to the slide block 3, the end of the adjusting screw 9 can move towards the abutment 10, thereby using the adjusting screw 9 to pre-press the waterstop 1000 against the abutment 10; at the same time, in order to avoid damaging the waterstop 1000 when the adjusting screw 9 rotates, in this embodiment, a pressure plate 11 is rotatably connected to the end of the adjusting screw 9 near the lower horizontal section 201 via a bearing or the like, the pressure plate 11 slides with the slide block 3, and an clearance groove 1011 is opened on the upper horizontal section 101 to slide with the pressure plate 11.

[0040] like Figure 1 As shown, in this embodiment, an end fixing mechanism is connected to the end of the upper horizontal section 101 and the end of the lower horizontal section 201. The end fixing mechanism includes a threaded end screw 12 and an end screw hole. The upper horizontal section 101 has a mating hole that mates with the end screw 12, and the end screw hole is located on the lower horizontal section 201. To improve the stability of the end screw 12 in fixing the ends of the upper horizontal section 101 and the lower horizontal section 201, in this embodiment, a pad 13 is fixedly connected to the top surface of the end of the lower horizontal section 201 by screws or welding. The top surface of the pad 13 contacts the bottom surface of the upper horizontal section 101, and the end screw hole is located on the pad 13.

[0041] The specific implementation process is as follows:

[0042] In this embodiment, when installing the embedded waterstop 1000, the lower template 2 is first fixed to the inverted arch mold in the prior art. All lower templates 2 can be fixed at once before fixing other components, or one lower template 2 can be fixed first, then the upper template 1 and other structures such as the waterstop 1000 can be connected before fixing the next lower template 2. For ease of operation, this embodiment uses the example of fixing all lower templates 2 at once before installing other structures. Simultaneously, to improve the stability of the lower templates after connection, adjacent fixing mechanisms are detachably connected between adjacent lower templates 2. For example, the adjacent fixing mechanism in this embodiment can be a fixing seat fixed to the lower vertical section 202 by screws or welding. Each lower vertical section 202 has two fixing seats, with the fixing seats facing each other between adjacent lower vertical sections 202. After the adjacent lower templates 2 are installed and fixed, bolts are used to fix the fixing seats on the adjacent lower vertical sections 202 to each other, thus making the connection between adjacent lower templates 2 more stable.

[0043] After all the lower formwork sections 2 are installed and fixed to form the lower formwork, place the waterstop 1000 on the top surface of the lower horizontal section 201, with half of the waterstop 1000 on the lower horizontal section 201 and the other half on one side of the lower vertical section 202 (this part of the waterstop 1000 is supported and fixed using existing steel bars, etc.). Then, use the waterstop pre-pressure adjustment mechanism connected to the slide block 3 to adjust the waterstop 1000. Specifically, first place the side of the waterstop 1000 on the lower horizontal section 201 between the pressure plate 11 and the clamping seat 10, and then manually use a wrench or other tools to rotate the adjusting screw 9 to adjust the waterstop 1000. The screw 9 pushes the pressure plate 11 close to the clamping seat 10, pressing the waterstop 1000 against the clamping seat 10. Then, a wrench or other tool is used to rotate the drive screw 5. The drive screw 5 rotates relative to the drive seat 4, pushing the slide 3 to slide relative to the lower horizontal section 201. This causes the pressure plate 11 and the clamping seat 10 connected to the slide 3 to slide synchronously, thereby adjusting the local position of the waterstop 1000 for more precise installation and fixation. After the local position of the waterstop 1000 is adjusted, the pressure plate 11 and the clamping seat 10 remain in their positions, providing pre-pressure fixation for the waterstop 1000, which facilitates the subsequent installation and fixation of the upper template 1.

[0044] After the pressure plate 11 and the clamping seat 10 on the slide block 3 are used to adjust and pre-press the waterstop 1000 locally, the upper template 1 can be installed and fixed. When fixing, first align the upper vertical section 102 and the lower vertical section 202 of the upper template 1 on the vertical plane, then make the upper horizontal section 101 fit against the upper surface of the waterstop 1000 to achieve the positioning of the upper template 1. Then insert the end screw 12 into the mating hole and rotate it to fix it with the end screw hole, so that the end of the upper horizontal section 101 is fixed with the end of the lower horizontal section 201. Finally, manually use a wrench or other tools to rotate the locking screw 8 so that the end of the locking screw 8 abuts against the top surface of the upper horizontal section 101, so that the upper horizontal section 101 and the lower horizontal section 201 stably clamp and fix the waterstop 1000.

[0045] In this embodiment, the sliding block 3 and the structure with pressure plate 11 and abutment 10 connected to the sliding block 3 can adjust the local position of the waterstop 1000, so that the waterstop 1000 can be installed more accurately. The pressure plate 11 and abutment 10 can pre-press and fix the waterstop 1000, which is convenient for the lower template 2 to accurately and completely fix the waterstop 1000. In addition, in this embodiment, the end screws 12 and locking screws 8 are used to fix the ends and middle positions of the lower horizontal section 201 and the upper horizontal section 101, respectively, so that the connection between the upper template 1 and the lower template 2 is more stable, and the invert arch casting is completed more stably.

[0046] Example 2

[0047] The difference between Example 2 and Example 1 is as follows: Figure 5 As shown, in this embodiment, an auxiliary support rod 14 is rotatably connected to the side of the upper vertical section 102 via a pin. The other end of the auxiliary support rod 14 is detachably connected to the invert arch mold in the prior art. After the upper sub-formwork 1 is installed and fixed, the auxiliary support rod 14 is then installed and fixed. The auxiliary support rod 14 provides auxiliary support for the upper sub-formwork 1, further improving the stability of the upper sub-formwork 1 installation and reducing the occurrence of grout leakage or mold bursting during the invert arch pouring process.
