Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering construction technology, specifically, it relates to a protective device for the construction process of a water-stopping copper sheet. Background Technology

[0002] Copper stoppers are crucial water-stopping structures used in hydraulic engineering at the joints of concrete water-stop sections. They effectively block water seepage paths, ensuring the seepage prevention performance and structural safety of hydraulic facilities. In actual construction, because the concrete water-stopping sections cannot be poured simultaneously, one side of the concrete must be poured first. At this stage, only half of the copper stopper is embedded in the already poured concrete, while the other half remains exposed until the other side is completed. During subsequent construction, the exposed copper stopper is highly susceptible to deformation, bending, or even breakage due to impacts from construction machinery, building materials, or debris, directly affecting the water-stopping effect. Therefore, protection of the exposed copper stopper during construction is necessary.

[0003] Currently, the common protection method used on construction sites is to make simple wooden boxes from solid wood and fix them to the exposed copper waterstop sheets. However, these wooden boxes are mostly of fixed size, which is not very adaptable to exposed sections of copper waterstop sheets of different lengths. When installing in sections, adjacent wooden boxes are prone to forming protective gaps due to size deviations, resulting in the exposure of some copper waterstop sheets. It is difficult to cope with construction and installation deviations, and the installation and disassembly are labor-intensive and have a low reuse rate.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To address the common problem of using simple wooden boxes to cover exposed copper water-stop sheets in construction sites, which often involve fixing them to exposed sections of copper water-stop sheets of varying lengths, this invention offers a solution. However, these boxes are typically of fixed dimensions, resulting in poor adaptability to different lengths of exposed copper water-stop sheets. During segmented installation, gaps can easily form between adjacent boxes due to dimensional discrepancies, exposing parts of the copper water-stop sheet. This makes it difficult to address installation deviations, and installation and disassembly are labor-intensive with low reusability. The basic concept of this invention is as follows:

[0006] A protective device for the construction process of a water-stop copper sheet includes a lower protective cover and an upper protective cover. The upper protective cover is hinged to the lower protective cover. A lower telescopic plate is slidably installed on the lower protective cover. An upper telescopic plate is slidably installed on the upper protective cover. A locking structure is provided between the upper and lower protective covers. A snap-fit ​​structure is provided between adjacent upper telescopic plates. The lower protective cover is anchored to the concrete surface by pre-embedded components or bolts.

[0007] In a preferred embodiment of this utility model, the lower protective cover, upper protective cover, upper telescopic plate and lower telescopic plate are made of plywood or plastic.

[0008] In a preferred embodiment of this utility model, both ends of the lower protective cover are provided with sliding grooves, and the lower telescopic plate is slidably installed in the sliding grooves. Both ends of the upper protective cover are provided with moving grooves, and the upper telescopic plate is slidably installed in the moving grooves.

[0009] In a preferred embodiment of this utility model, a baffle is installed at the bottom of the upper telescopic plate, and a groove adapted to the baffle is provided on the lower telescopic plate, wherein the baffle is inserted into the groove.

[0010] In a preferred embodiment of the present invention, the snap-fit ​​structure includes two slots formed in one of the upper telescopic plates and two mounting slots formed in the other upper telescopic plate. A snap-fit ​​block is rotatably installed in the mounting slot. A torsion spring is connected between the snap-fit ​​block and the upper telescopic plate. The end of the snap-fit ​​block is hook-shaped and adapted to the snap-fit ​​slot.

[0011] In a preferred embodiment of this utility model, a support plate is connected to both the lower protective cover and the lower telescopic plate, and the support plate is located on the side of the lower protective cover and the lower telescopic plate facing the water-stop copper sheet.

[0012] In a preferred embodiment of the present invention, the locking structure includes a locking groove formed in the lower protective cover and a bolt engaged with the upper protective cover, the end of the bolt being a smooth rod adapted to the locking groove.

[0013] In a preferred embodiment of this utility model, a guide surface is provided on the outer side of the end of the card block.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This utility model utilizes the sliding cooperation between the upper and lower telescopic plates, combined with the fixing of the baffle and the groove, as well as the locking block and the groove, to flexibly adjust the protective length, adapt to different exposed sections of the water-stopping copper sheets, and fill the gaps between adjacent devices to achieve comprehensive protection. The hinged structure and bolt locking design of the upper and lower protective covers reduce the difficulty of operation and make installation and disassembly easier. It can be reused after disassembly, improving utilization while reducing construction costs.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] like Figures 1 to 6 As shown, a protective device for the construction process of a water-stop copper sheet includes a lower protective cover 1 and an upper protective cover 2. The upper protective cover 2 is hinged to the lower protective cover 1. A lower telescopic plate 4 is slidably installed on the lower protective cover 1, and an upper telescopic plate 3 is slidably installed on the upper protective cover 2. A locking structure is provided between the upper protective cover 2 and the lower protective cover 1, and a snap-fit ​​structure is provided between adjacent upper telescopic plates 3. The lower protective cover 1 is anchored to the concrete surface by pre-embedded components or bolts. In this setup, the lower protective cover 1 serves as the installation base of the device and is connected to the concrete by pre-embedded components or bolts. The upper protective cover 2 can be flipped open and closed around the lower protective cover 1 to facilitate covering and protecting the water-stop copper sheet 10. The sliding fit between the upper telescopic plate 3 and the lower telescopic plate 4 can compensate for the installation gap between adjacent devices. The locking structure ensures the stability of the upper and lower protective covers after they are closed, and the snap-fit ​​structure realizes the connection and fixation of adjacent telescopic plates.

[0027] like Figures 1 to 6As shown, in a specific embodiment, the lower protective cover 1, the upper protective cover 2, the upper telescopic plate 3, and the lower telescopic plate 4 are made of plywood or plastic. In this configuration, plywood or plastic materials are lightweight, easy to process, and inexpensive, which facilitates handling and installation by construction personnel, while also meeting the protective strength requirements for the water-stop copper sheet 10, preventing damage to the water-stop copper sheet 10 from construction collisions.

[0028] like Figures 1 to 6 As shown, furthermore, both ends of the lower protective cover 1 are provided with sliding grooves 100, and the lower telescopic plate 4 is slidably installed in the sliding grooves 100; both ends of the upper protective cover 2 are provided with moving grooves 200, and the upper telescopic plate 3 is slidably installed in the moving grooves 200. In this configuration, the sliding grooves 100 provide a sliding track for the lower telescopic plate 4, restricting the movement direction of the lower telescopic plate 4, while the moving grooves 200 play the same guiding and limiting role for the upper telescopic plate 3.

[0029] like Figures 1 to 6 As shown, furthermore, a baffle 5 is installed at the bottom of the upper telescopic plate 3, and a retaining groove 6 adapted to the baffle 5 is opened on the lower telescopic plate 4, with the baffle 5 snapping into the retaining groove 6. In this configuration, when the upper telescopic plate 3 is dragged to slide along the moving groove 200, the baffle 5 will generate a pushing force on the retaining groove 6, causing the lower telescopic plate 4 to move synchronously along the sliding groove 100, ensuring that the telescopic structure always remains in contact, and together achieving sealing compensation for the gap of the device.

[0030] like Figures 1 to 6 As shown, the snap-fit ​​structure further includes two slots 9 formed in one of the upper telescopic plates 3, and two mounting slots 7 formed in the other upper telescopic plate 3. A snap-fit ​​block 8 is rotatably mounted in the mounting slot 7. A torsion spring connects the snap-fit ​​block 8 to the upper telescopic plate 3. The end of the snap-fit ​​block 8 is hook-shaped and fits into the slot 9. In this configuration, when adjacent upper telescopic plates 3 are in contact, the hook-shaped snap-fit ​​block 8 can be snapped into the slot 9 under the action of the torsion spring, achieving a stable connection between the two upper telescopic plates 3.

[0031] like Figures 1 to 6 As shown, furthermore, a support plate 11 is connected to both the lower protective cover 1 and the lower telescopic plate 4. The support plate 11 is located on the side of the lower protective cover 1 and the lower telescopic plate 4 facing the water-stop copper sheet 10. In this configuration, the support plate 11 contacts the bottom of the water-stop copper sheet 10, thus providing support for the water-stop copper sheet 10.

[0032] like Figures 1 to 6 As shown, the locking structure further includes a locking groove 12 formed in the lower protective cover 1 and a bolt 13 engaged with the upper protective cover 2. The end of the bolt 13 is a smooth rod, which is adapted to the locking groove 12. In this configuration, after the upper protective cover 2 is closed, the bolt 13 can be rotated to move downward along the thread, and the smooth rod at its end can be inserted into the locking groove 12, locking the upper protective cover 2 and the lower protective cover 1.

[0033] like Figures 1 to 6 As shown, a guide surface is provided on the outer side of the end of the locking block 8. In this configuration, the guide surface can convert the contact force of the upper telescopic plate 3 into the rotational force of the locking block 8 during the contact process of the adjacent upper telescopic plate 3, guide the locking block 8 to automatically rotate around the mounting groove 7 and compress the torsion spring. When the locking block 8 moves to the position of the locking groove 9, the torsion spring resets and the locking is achieved.

[0034] The implementation principle of the protective device for the construction process of the water-stop copper sheet in this embodiment is as follows: First, the lower protective cover 1 is anchored to the poured concrete by a pre-embedded component or matching bolts. During installation, it is necessary to ensure that the inner side of the lower protective cover 1 is aligned with the exposed part of the water-stop copper sheet 10. At this time, the lower protective cover 1 and the support plate 11 connected to it will fit against the bottom and side of the water-stop copper sheet 10, providing support and protection for the water-stop copper sheet 10 and preventing deformation caused by impact from debris or contact with personnel during subsequent construction. Rotate the upper protective cover 2, which is hinged to the top edge of the lower protective cover 1, so that the inner side of the upper protective cover 2 fits against the upper surface of the water-stop copper sheet 10, ensuring that the exposed part of the water-stop copper sheet 10 is completely covered by the upper and lower protective structures. Then rotate the bolt 13, so that the bolt 13 moves downward along the threaded hole of the upper protective cover 2 until the smooth part of the bolt 13 at the end is engaged in the locking groove 12 opened at the corresponding position of the lower protective cover 1. At this time, the upper protective cover 2 and the lower protective cover 1 are locked and fixed, and cannot rotate relative to each other.

[0035] Because the exposed length of the water-stop copper sheet 10 in the construction scene is relatively long, the protective device needs to be installed in sections. Gaps may easily appear between adjacent sections due to installation errors. At this time, the telescopic structure can be used for sealing compensation. Dragging the upper telescopic plate 3 in the moving groove 200 at both ends of the upper protective cover 2, the upper telescopic plate 3 can slide freely along the length direction of the moving groove 200. At the same time, because the baffle 5 integrally formed at the bottom of the upper telescopic plate 3 is inserted into the baffle groove 6 opened in the lower telescopic plate 4, when the upper telescopic plate 3 moves, it will simultaneously drive the lower telescopic plate 4 to slide along the sliding groove 100 at both ends of the lower protective cover 1 until the end faces of the upper telescopic plates 3 of the two adjacent protective devices are completely attached, and the lower telescopic plate 4 is also attached, eliminating the gap between the two sections of the device.

[0036] During the fitting process of adjacent upper telescopic plates 3, the locking block 8, which is rotatably installed in the mounting groove 7 on the side of one upper telescopic plate 3, will first contact the end of the other upper telescopic plate 3 through the guide surface at its end. As the upper telescopic plates 3 continue to move, the locking block 8 is subjected to a resisting force and rotates counterclockwise around the pivot in the mounting groove 7 (towards...). Figure 6(Based on this), the torsion spring connecting the locking block 8 and the upper telescopic plate 3 is simultaneously compressed. When the hook-shaped end of the locking block 8 moves to the corresponding slot 9 on the other upper telescopic plate 3, the resistance disappears, the torsion spring resets and drives the locking block 8 to reset, so that the hook-shaped end of the locking block 8 is engaged in the slot 9, realizing the locking and fixing of the adjacent upper telescopic plates 3, and the lower telescopic plate 4 is also positioned accordingly. Through this process, all the segmented protective devices form a continuous protective structure, ensuring that the exposed water-stop copper sheet 10 has no exposed area, and completely isolating it from collisions, squeezing and contamination by debris during construction.
