Description

Technical Field

[0001] This utility model relates to the field of waterproof structure technology, specifically to a waterproof structure with advanced water-stopping post-pouring strip in water-rich areas. Background Technology

[0002] Post-pouring strips are temporary construction joints left at corresponding locations in foundation slabs, walls, and beams during building construction to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to uneven temperature and shrinkage. Effective waterproofing is required inside the post-pouring strip during its construction.

[0003] A search revealed that patent number CN218622342U discloses a waterproof structure for post-pouring strips in basements. This waterproof structure is equipped with an adjustment mechanism. By turning the handle, the adjustment mechanism causes the rotating rod to rotate. The first bevel gear and the second bevel gear engage, and the sprocket and the chain engage, causing the two screws to rotate simultaneously, driving the moving rod to rise and fall, thereby adjusting the top slab. Compared with traditional waterproof structures for post-pouring strips in basements, this structure allows for height adjustment, making it adaptable to different sizes.

[0004] Because the post-pouring strip is currently constructed with a recessed design, debris and gravel can easily get into it before pouring. This requires manual cleaning of the post-pouring strip during the pouring process, which is time-consuming and cannot guarantee the cleaning effect. As a result, the post-pouring strip has a poor pouring effect and cannot achieve an effective waterproofing effect. Utility Model Content

[0005] In view of the problems existing in the above-mentioned waterproof structures with advanced water-stopping and post-pouring strips in water-rich areas, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a waterproof structure for advanced water-stopping post-pouring strips in water-rich areas, which solves the problem that the internal gravel cannot be effectively cleaned after the construction of the post-pouring strip, resulting in poor subsequent pouring effect and reduced waterproofing effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A waterproof structure for advanced water-stopping post-pouring strips in water-rich areas includes a base layer and a post-pouring strip pit located on top of the base layer. The inner wall of the post-pouring strip pit is lined with a water-blocking steel plate, which is in contact with the surface of the base layer. A waterproof membrane is laid on the surface of the water-blocking steel plate. Grooves are provided at both ends of the top of the water-blocking steel plate. A slider is provided on the inner wall of the groove via an elastic sliding mechanism. The slider is fixedly connected to the bottom of the waterproof membrane. An adjustment and positioning mechanism is provided between the side wall of the slider and the inner wall of the groove.

[0009] Preferably, the elastic sliding mechanism includes a crossbar, which is fixedly disposed in the groove and slides through the inside of the slider. The crossbar has multiple spaced hook grooves on its wall and a first spring is sleeved on its wall. The two ends of the first spring are fixedly connected to the slider and the crossbar, respectively.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a waterproof structure with advanced water-stopping post-pouring strip in water-rich areas.

[0025] This utility model provides, for example Figure 1-3 The above describes a waterproof structure for a pre-cast water-stopping strip in a water-rich area, comprising a base layer 1 and a post-cast strip pit 2 located on top of the base layer 1. The inner wall of the post-cast strip pit 2 is covered with a water-blocking steel plate 3, which is made of multiple steel plates welded together. The water-blocking steel plate 3 is in contact with the surface of the base layer 1. A waterproof membrane 4 is laid on the surface of the water-blocking steel plate 3, and a waterproof coating 13 is applied to the outer wall of the waterproof membrane 4. Grooves are provided at both ends of the top of the water-blocking steel plate 3. A slider 5 is provided on the inner wall of the groove through an elastic sliding mechanism. The slider 5 is fixedly connected to the bottom of the waterproof membrane 4. The elastic sliding mechanism includes a crossbar 6, which is fixedly located in the groove and slides through the inside of the slider 5. The bar wall of the crossbar 6 has multiple spaced grooves, and a first spring 7 is sleeved on the bar wall of the crossbar 6. The two ends of the first spring 7 are fixedly connected to the slider 5 and the crossbar 6, respectively.

[0026] After the post-pouring strip pit 2 is prepared, the water-blocking steel plate 3 is first installed inside the post-pouring strip pit 2, and the waterproof membrane 4 is laid on the surface of the water-blocking steel plate 3. Finally, the waterproof coating 13 is applied to the surface of the waterproof membrane 4. Then, when it is necessary to pour the post-pouring strip pit 2, the waterproof membrane 4 can be straightened by the lateral sliding of the slider 5 and the crossbar 6 and under the elastic support of the first spring 7. At this time, the waterproof membrane 4 is set horizontally. Then the position of the waterproof membrane 4 is fixed, which makes it easier for the staff to clean the gravel and debris on the surface of the waterproof membrane 4, so as to ensure effective and stable pouring inside the post-pouring strip pit 2, thereby improving the waterproof effect inside the post-pouring strip.

[0027] In order to fix the position of the waterproof membrane 4 after it is straightened, such as Figure 2-3As shown, an adjustment and positioning mechanism is provided between the side wall of the slider 5 and the inner wall of the groove. The adjustment and positioning mechanism includes a slide plate 8. A moving groove is provided at the upper end of the outer wall of the slider 5. A vertical rod 9 is fixedly provided inside the moving groove. The slide plate 8 is slidably sleeved on the outside of the vertical rod 9, and a hook 10 is rotatably sleeved at its end. A rotating rod 12 is rotatably passed through the inside of the slide plate 8. The hook 10 is fixedly sleeved on the outside of the rotating rod 12. The hook 10 is engaged with the hook groove. A second spring 11 is sleeved on the rod wall of the vertical rod 9. The two ends of the second spring 11 are fixedly connected to the slide plate 8 and the vertical rod 9, respectively.

[0028] Before straightening the waterproof membrane 4, pull the hook 10 out of the groove. At this time, under the elastic force of the second spring 11, the slide plate 8 can move up along the vertical bar 9 and away from the horizontal bar 6. Then, stretch one end of the waterproof membrane 4 so that the slider 5 can stretch the waterproof membrane 4 by sliding with the horizontal bar 6. After the waterproof membrane 4 is straightened, pull down the hook 10 and lock it in the groove to fix the position of the slider 5, thus ensuring the stability of the position of the waterproof membrane 4.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
