Description

Technical Field

[0001] This application belongs to the field of building foundation construction technology, and more specifically, it relates to a steel plate waterstop protection device for subway construction. Background Technology

[0002] During the construction of subway stations, the side walls are poured in multiple stages from bottom to top. Horizontal construction joints exist between each pour. To ensure waterproofing, steel plate waterstops (water-stop steel plates) are installed to cut off these horizontal construction joints. The lower part of the steel plate waterstop is embedded in the concrete poured below. When pouring the upper part, the upper part of the steel plate waterstop is embedded into the newly poured section, thus cutting off the horizontal construction joint.

[0003] However, when pouring the concrete below, the upper part of the steel plate waterstop is easily splashed with concrete, soil and other contaminants, which are difficult to clean, thus affecting the water-stopping effect of the steel plate waterstop. In addition, in the existing technology, the steel plate waterstop is usually fixed by welding positioning bars (steel bars) on the steel plate waterstop. Due to the small operating space, the welding workload is large, and there is a possibility of welding through the steel plate waterstop during the welding process, which affects the water-stopping effect.

[0024] Please refer to the following: Figures 1 to 3 As shown, the following describes a protective device for a steel plate waterstop 1 used in subway construction provided by an embodiment of this application. This utility model provides a protective device for a steel plate waterstop 1 used in subway construction, comprising a steel plate waterstop 1, a U-shaped cover 2, a first positioning part 3, and a connecting component 5. The steel plate waterstop 1 is existing technology, and its main function is to prevent moisture from seeping into the building structure through concrete construction joints. It should be noted that the upper and lower ends of the steel plate waterstop 1 are respectively provided with folded edges 11. The free ends of the folded edges 11 at the upper and lower ends extend upwards or downwards in a direction away from the steel plate waterstop 1, so that the inclined folded edges 11 can be better embedded in the concrete, reducing the possibility of water seeping from the edge of the steel plate waterstop 1, thereby improving the water-stopping effect. Further details will not be elaborated here.

[0025] A U-shaped cover 2 is installed on the upper part of the steel plate waterstop 1 to prevent concrete, soil, and other contaminants from splashing onto the upper part of the steel plate waterstop 1 during construction, ensuring that its water-stopping effect is not affected. In this embodiment, the side of the U-shaped cover 2 closest to the folded edge 11 is defined as the positioning side 21. The first positioning part 3 is set on the upper part of the positioning side 21 to fix the U-shaped cover 2 and the steel plate waterstop 1, that is, the first positioning part 3 prevents relative movement between the U-shaped cover 2 and the steel plate waterstop 1. The connecting component 5 is set on the top of the U-shaped cover 2 for fixed connection with the external reinforcing bars at the construction site, so as to position the steel plate waterstop 1 and prevent the steel plate waterstop 1 from shifting during concrete pouring.

[0026] In practice, the U-shaped cover 2 is placed over the upper part of the steel plate waterstop 1, so that the positioning side 21 is close to the folded edge 11 of the steel plate waterstop 1. At this time, the side of the steel plate waterstop 1 away from the folded edge 11 abuts against the inner wall of the U-shaped cover 2. Then, the U-shaped cover 2 and the steel plate waterstop 1 are fixed to each other by the first positioning part 3. Then, the U-shaped cover 2 is connected and fixed to the external steel bars by the connecting component 5. In this way, the installation efficiency of the steel plate waterstop 1 is improved, and the problem of welding through the steel plate waterstop 1 and affecting the water-stopping effect in the prior art is avoided.

[0027] In this embodiment, the first positioning part 3 includes at least one first bolt 31 screwed onto the U-shaped cover 2. One end of the first bolt 31 passes through the U-shaped cover 2 and abuts against the steel plate waterstop 1. The U-shaped cover 2 is stably fixed to the steel plate waterstop 1 via a threaded connection. It should be noted that in this embodiment, two first bolts 31 are used to make the connection between the U-shaped cover 2 and the steel plate waterstop 1 more secure, but this is not a limitation; the number of first bolts 31 can be increased or decreased according to the actual site conditions. During implementation, the operator rotates the first bolt 31 so that one end passes through the U-shaped cover 2 and gradually abuts against the steel plate waterstop 1. Then, by tightening the first bolt 31, the U-shaped cover 2 is tightly fixed to the steel plate waterstop 1.

[0028] Preferably, the first bolt 31 is rotatably connected to an anti-slip pad 32 at one end near the steel plate waterstop 1, and the inner wall of the U-shaped cover 2 near the positioning side 21 is provided with a groove 22 for accommodating the anti-slip pad 32 (e.g., Figure 3 (As shown). By setting the anti-slip pad 32, the friction between the first bolt 31 and the steel plate waterstop 1 is increased, preventing the waterstop steel plate from moving due to vibration or other reasons during construction. The groove 22 can accommodate the anti-slip pad 32. Before installing the U-shaped cover 2, the first bolt 31 can be rotated to move the anti-slip pad 32 into the groove 22, avoiding the anti-slip pad 32 blocking the movement of the steel plate waterstop 1 during installation.

[0029] In this embodiment, a positioning block 23 is fixedly provided at the top of the inside of the U-shaped cover 2, and the bottom surface of the positioning block 23 is an inclined surface adapted to the folded edge 11. By adapting the inclined surface of the bottom surface of the positioning block 23 to the folded edge 11, the U-shaped cover 2 can be better positioned, making the installation of the U-shaped cover 2 and the steel plate waterstop 1 more accurate and further improving stability.

[0030] In this embodiment, a baffle 4 is provided at the bottom end of the positioning side 21, and the end of the baffle 4 away from the positioning side 21 abuts against the steel plate waterstop 1. By providing the baffle 4, the U-shaped cover 2 can be further positioned, making the installation more stable, and preventing contaminants such as concrete and soil from splashing onto the upper part of the steel plate waterstop 1 through the opening at the bottom of the U-shaped cover 2 during construction. Preferably, the inner wall of the U-shaped cover 2 near the positioning side 21 is provided with a receiving groove 24 for accommodating the baffle 4 (e.g., Figure 3 As shown), the end of the baffle 4 away from the steel plate waterstop 1 is rotatably set at the bottom of the receiving groove 24 via the pin 41. When one end of the baffle 4 abuts against the steel plate waterstop 1, the bottom surface of the baffle 4 abuts against the bottom surface of the receiving groove 24 to prevent the baffle 4 from continuing to rotate downward.

[0031] In implementation, the U-shaped cover 2 is first fitted onto the upper part of the steel plate waterstop 1. At this time, the baffle 4 is located in the receiving groove 24 to facilitate the installation of the steel plate waterstop 1. Then, the baffle 4 is rotated out of the receiving groove 24 so that one end abuts against the steel plate waterstop 1, serving as a positioning and protective function. When it is necessary to disassemble the U-shaped cover 2, the baffle 4 is rotated back into the receiving groove 24 to facilitate the removal of the U-shaped cover 2. The baffle 4 is rotatably set in the receiving groove 24 by the pin 41, which makes it easier to rotate the baffle 4 to the appropriate position when installing and disassembling the U-shaped cover 2, making the operation more convenient. It should be noted that when the baffle 4 abuts against the steel plate waterstop 1, its bottom surface abuts against the bottom surface of the receiving groove 24, which can ensure the accuracy and stability of the positioning of the baffle 4.

[0032] Preferably, a second bolt 42 is screwed onto one side of the receiving groove 24. One end of the second bolt 42 extends through the side wall of the receiving groove 24 into the interior of the U-shaped cover 2. When one end of the baffle 4 abuts against the steel plate waterstop 1, the radial side of the second bolt 42 abuts against the top surface of the baffle 4. In practice, when it is necessary to fix the steel plate waterstop 1, the second bolt 42 is rotated so that one end of the second bolt 42 extends through the side wall of the receiving groove 24 into the interior of the U-shaped cover 2. This allows the second bolt 42 to push one end of the baffle 4 towards the steel plate. When the baffle 4 abuts against the steel plate waterstop 1, the radial side of the second bolt 42 abuts against the top surface of the baffle 4, thereby fixing the baffle 4 in place. That is, by setting the second bolt 42, the baffle 4 can be further fixed, preventing displacement of the baffle 4 during construction and ensuring the stable and reliable positioning of the U-shaped cover 2.

[0033] In this embodiment, a threaded groove 43 is provided on one side of the baffle 4. When the baffle 4 is rotated into the receiving groove 24, the second bolt 42 is screwed into the threaded groove 43. Specifically, when it is necessary to separate the U-shaped cover 2 from the steel plate waterstop 1, firstly rotate the second bolt 42 to move it away from the U-shaped cover 2, so that it is no longer in contact with the top surface of the baffle 4. At the same time, the worker pushes the baffle 4 to rotate it into the receiving groove 24. At this time, the threaded groove 43 on the baffle 4 corresponds to one end of the second bolt 42, thereby screwing the second bolt 42 into the threaded groove 43 to fix the baffle 4, thus facilitating the removal of the steel plate waterstop 1.

[0034] In this embodiment, the connecting component 5 includes a first screw 51 and a clamping part 53. The first screw 51 is horizontally arranged and slidably passes through the top of the U-shaped cover 2. First nuts 52 are screwed onto both sides of the first screw 51 to lock the first screw 51 and prevent it from moving. The clamping part 53 is used to clamp external reinforcing bars at the construction site and is fixed to the end of the first screw 51 away from the U-shaped cover 2. The clamping part 53 of the connecting component 5 fixes the U-shaped cover 2 to a preset position at the construction site.

[0035] It should be noted that the first screw 51 can slide horizontally at the top of the U-shaped cover 2. By adjusting the position of the first screw 51, it can be adapted to connect with external steel bars at different positions. The two first nuts 52 are used to fix the position of the first screw 51 on the U-shaped cover 2. The clamping part 53 can firmly clamp the external steel bars, so as to achieve a stable connection between the U-shaped cover 2 and the external steel bars.

[0036] Preferably, there are multiple connecting components 5, which are arranged at intervals on one or both sides of the U-shaped cover 2. The interval arrangement of multiple connecting components 5 can make the connection between the U-shaped cover 2 and the external steel bars more stable and improve the stability of the U-shaped cover 2.

[0037] In this embodiment, the clamping part 53 includes a first clamping block 531 fixed to the first screw 51 and a second clamping block 532 disposed on the side of the first clamping block 531 away from the U-shaped cover 2. A second screw 533 is fixed to one side of the second clamping block 532. One end of the second screw 533 slides through the first clamping block 531 and is screwed with a second nut 534. In practice, the reinforcing bar is clamped between the first clamping block 531 and the second clamping block 532. Then, the position of the second clamping block 532 is adjusted according to the diameter of the reinforcing bar so that one end of the second screw 533 slides through the first clamping block 531. Then, the second nut 534 is tightened so that the first clamping block 531 and the second clamping block 532 clamp the reinforcing bar.

[0038] In the specific implementation of this utility model, firstly, the U-shaped cover 2 is placed over the upper part of the steel plate waterstop 1 so that the positioning side 21 is close to the folded edge 11 of the steel plate waterstop 1. At the same time, the inclined surface of the bottom of the positioning block 23 is attached to the folded edge 11 of the steel plate waterstop 1. At this time, the baffle 4 is located in the receiving groove 24, and the second bolt 42 is screwed into the threaded groove 43. Then, the second bolt 42 is rotated to disengage it from the receiving groove 24. Then, the baffle 4 is rotated so that one end moves toward the steel plate waterstop 1 and abuts against the steel plate waterstop 1. At this time, the second bolt 42 is rotated so that one end moves toward the inside of the U-shaped cover 2 to further fix the baffle 4 and prevent the baffle 4 from shifting during construction.

[0039] Next, the first bolt 31 is rotated, which in turn moves the anti-slip pad 32 towards the steel plate waterstop 1 and abuts against it. The friction of the anti-slip pad 32 is used to fix the relative position of the U-shaped cover 2 and the steel plate waterstop 1. Then, according to the position of the external reinforcing bars, the first screw 51 is slid and the two first nuts 52 are tightened to fix the first screw 51 at a suitable position on the top of the U-shaped cover 2. Simultaneously, the first clamping block 531 and the second clamping block 532 are placed on the external reinforcing bars. The spacing between the clamping blocks is adjusted by the second screw 533 and the second nut 534 to clamp the reinforcing bars, thus achieving the connection between the U-shaped cover 2 and the external reinforcing bars.

[0040] After installation, the U-shaped cover 2 effectively prevents contaminants such as concrete and soil from splashing onto the upper part of the steel plate waterstop 1. In other words, the U-shaped cover 2 effectively prevents contamination of the upper part of the steel plate waterstop 1, ensuring the water-stopping effect. The installation of the baffle 4, the first positioning part 3, and the connecting component 5 makes the installation of the steel plate waterstop 1 convenient and stable, improving construction efficiency. The installation of anti-slip pads 32 and positioning blocks 23 enhances the stability of the device, solving the problems of insufficient protection and difficulty in fixing the steel plate waterstop 1 in existing technologies.

[0041] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
