Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a post-cast strip water-stopping system and a post-cast strip water-stopping construction method for basement exterior walls. Background Technology

[0002] In building construction, the demand for large basement structures is gradually increasing. To prevent harmful cracks from forming between the basement structure and the main building structure due to uneven settlement or the hardening process of large-volume concrete, which could affect the basement structure and other buildings above it, a post-cast strip can be left at an appropriate location on the basement exterior wall as needed. The post-cast strip needs to be sealed by a second pour after the main structure of the exterior walls on both sides has basically stabilized and most of the previously poured concrete has shrunk.

[0003] At the post-cast strip, a horizontal joint is formed that runs through the entire wall, connecting the old and new concrete. This joint is the weakest point in the underground waterproofing and the most prone to leakage. Furthermore, the overall height of the post-cast strip is higher than the height of the exterior wall, making the installation efficiency of splicing multiple waterproofing slabs in the post-cast strip relatively low. Summary of the Invention

[0004] This invention is made to solve the above-mentioned technical problems. Its purpose is to provide a post-cast strip water-stopping system for basement exterior walls. By setting matching connectors on the foundation slab and the standard slab, the foundation slab and the standard slab, as well as the standard slabs themselves, can be quickly connected, thereby improving the installation efficiency of the post-cast strip water-stopping system.

[0005] To achieve the above objectives, the present invention provides a post-cast strip water-stopping system for basement exterior walls, installed on one side of the basement exterior wall, comprising: a base plate, including a first main body and an installation part, the installation part being disposed above the first main body, the top of the installation part having a first installation block protruding therefrom, and the middle of the installation part having a first limiting groove; multiple standard plates, including a second main body, a first connecting part and a second connecting part, the first connecting part and the second connecting part being respectively disposed above and below the second main body; and a water-stopping screw, vertically connected to the base plate and the standard plates; wherein, the second connecting part includes a limiting block corresponding to the first limiting groove, and the edge of the second connecting part forming an installation groove that mates with the first installation block; the top of the first connecting part has a second installation block protruding therefrom that mates with the installation groove, and the middle of the first connecting part has a second limiting groove, the second limiting groove corresponding to the first limiting groove and the limiting block.

[0006] Preferably, there are two first mounting blocks and two second mounting blocks, respectively disposed on both sides of the mounting portion and the first connecting portion, and two mounting slots are provided accordingly.

[0007] Preferably, the angle between the end face of the second mounting block and the end face of the second main body, and the angle between the end face of the first mounting block and the end face of the mounting part are both acute angles.

[0008] Preferably, both the first main body and the second main body are provided with connecting holes, and the water-stop screw is fixedly connected to the connecting holes.

[0009] Preferably, the water-stop screw further includes a sealing element, which is installed in the connecting hole.

[0010] Preferably, the water-stop screw rod further includes a water-stop steel sheet, which is installed in the middle of the water-stop screw rod.

[0011] Preferably, the template is installed on the other side of the basement exterior wall and connected to the water-stop bolt.

[0012] Preferably, the template is arranged parallel to the standard plate.

[0013] Preferably, the water-stop screw also includes a mounting buckle connected to the template.

[0014] This invention provides a method for constructing a water-stopping system for post-cast strips on basement exterior walls, applicable to any of the aforementioned water-stopping systems for basement exterior walls. The method includes obtaining the dimensions of the basement exterior wall structure; hoisting a foundation plate to fit one side of the exterior wall structure; hoisting a template to install on the other side of the exterior wall structure; connecting the foundation plate and the template using water-stopping bolts; hoisting a standard plate and connecting the second connecting part of the standard plate to the mounting part of the foundation plate; connecting the standard plate and the template using the water-stopping bolts; hoisting the standard plates and stacking them sequentially, connecting the standard plates and the template using the water-stopping bolts, until the top of the standard plate is higher than the top of the exterior wall structure.

[0015] Based on the above description and practice, the post-cast strip water-stopping system for basement exterior walls described in this invention is installed on one side of the basement exterior wall and includes a base plate, a standard plate, and water-stopping bolts. The base plate includes a first main body and an installation part, with the installation part positioned above the first main body for connection to the standard plate. A first installation block protrudes from the top of the installation part, and a first limiting groove is formed in the middle of the installation part. The base plate and the standard plate are fixed together by the first installation block and the first limiting groove. Multiple standard plates are provided, including a second main body, a first connecting part, and a second connecting part, respectively positioned above and below the second main body. The first and second connecting parts of multiple standard plates can be connected sequentially until the height of the entire post-cast strip water-stopping system is higher than the height of the basement exterior wall. The water-stopping bolts are vertically connected to the base plate and the standard plates, resisting the lateral pressure of the concrete while also diverting any accidentally leaked water to prevent it from affecting the basement exterior wall. The second connecting part includes a limiting block corresponding to the first limiting groove, and an installation groove that mates with the first installation block is formed on the edge of the second connecting part. The top of the first connecting part has a protruding second mounting block that mates with the mounting groove, and the middle part has a second limiting groove, which corresponds to the first limiting groove and the limiting block. When connecting the standard plate and the base plate, the first limiting groove engages with the limiting block, and the mounting groove engages with the first mounting block, achieving a stable connection between the standard plate and the base plate through double fixing. When connecting two standard plates, the second mounting block engages with the mounting groove, and the second limiting groove engages with the limiting block to complete the connection. Furthermore, since the second limiting groove in the middle of the first connecting part is a through hole, when stacking multiple standard plates upwards, the hook can pass through the second limiting groove to lift the standard plate and align it with another standard plate or base plate to complete the assembly. This saves lifting costs, further simplifies the standard plate splicing steps, and improves the installation efficiency of the post-pouring strip waterstop system for the entire basement exterior wall.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] This invention discloses a post-cast strip water-stopping system for basement exterior walls. Please refer to [link / reference]. Figures 1 to 6 The post-cast strip water-stop system for the basement exterior wall is installed on one side of the basement exterior wall 10 and includes a base plate 1, a standard plate 2, and water-stop bolts 3. The base plate 1 includes a first main body 11 and an mounting part 12. The mounting part 12 is located above the first main body 11 and is used to connect with the standard plate 2. A first mounting block 13 protrudes from the top of the mounting part 12, and a first limiting groove 14 is formed in the middle of the mounting part 12. The base plate 1 and the standard plate 2 are fixed together by the first mounting block 13 and the first limiting groove 14. Multiple standard plates 2 are provided, including a second main body 21, a first connecting part 22, and a second connecting part 23. The first connecting part 22 and the second connecting part 23 are respectively located above and below the second main body 21. The first connecting parts 22 and the second connecting parts 23 of multiple standard plates 2 can be connected sequentially until the height of the entire post-cast strip water-stop system is higher than the height of the basement exterior wall 10. The water-stop screw 3 is vertically connected to the base slab 1 and the standard slab 2, resisting the lateral pressure of the concrete while also diverting any accidentally leaked water to prevent it from affecting the basement exterior wall 10. The second connecting part 23 includes a limiting block 24 corresponding to the first limiting groove 14, and an installation groove 25 formed on the edge of the second connecting part 23 to mate with the first installation block 13. The top of the first connecting part 22 has a protruding second installation block 26 that mates with the installation groove 25, and the middle has a second limiting groove 27, which corresponds to the first limiting groove 14 and the limiting block 24. When the standard slab 2 and the base slab 1 are connected, the first limiting groove 14 engages with the limiting block 24, and the installation groove 25 engages with the first installation block 13, achieving a stable connection between the standard slab 2 and the base slab 1 through double fixing. When two standard slabs 2 are connected, the second installation block 26 engages with the installation groove 25, and the second limiting groove 27 engages with the limiting block 24, completing the connection. Furthermore, since the second limiting groove 27 in the middle of the first connecting part 22 is a through hole, when multiple standard plates 2 are stacked upwards, the hook can pass through the second limiting groove 27 to lift the standard plate 2 and align it with another standard plate 2 or the base plate 1 to complete the assembly. This can save lifting costs, further simplify the splicing steps of the standard plate 2, and improve the installation efficiency of the post-pouring strip water-stop system of the entire basement exterior wall 10.

[0027] To ensure the stability of the connection between the base plate 1 and the standard plate 2, and between the standard plate 2 and itself, in some embodiments, two first mounting blocks 13 and two second mounting blocks 26 are provided, respectively located on both sides of the mounting portion 12 and the first connecting portion 22, and two corresponding mounting slots 25 are provided. When fixing the standard plate 2 to the base plate 1 or the standard plate 2, the connection strength is further enhanced by engaging the two first mounting blocks 13 and the two second mounting blocks 26 with the mounting slots 25. This prevents the second mounting block 26 from detaching from the mounting slot 25 when the crane collides with the standard plate 2 during stacking, thus preventing the standard plate 2 from falling off, causing a safety accident, or affecting the overall installation efficiency.

[0028] To prevent groundwater leakage from cutting off its seepage path and reducing seepage efficiency, in some embodiments, the angle between the end face of the second mounting block 26 and the end face of the second main body 21, and the angle between the end face of the first mounting block 13 and the end face of the mounting part 12, are acute angles, specifically 30 degrees, 50 degrees, 60 degrees, 70 degrees, etc. This increases the contact area between the post-cast strip water-stop system and the basement exterior wall 10, strengthening their connection and reducing potential cracks at the contact point. Furthermore, compared to a flat installation, groundwater leaks and needs to travel a longer path to reach the exterior wall, further reducing the impact of groundwater on the basement exterior wall 10.

[0029] Furthermore, in some embodiments, the angle between the end face of the second mounting block 26 and the end face of the second main body 21, and the angle between the end face of the first mounting block 13 and the end face of the mounting part 12 are both 45 degrees, so that the infiltration path of groundwater is no longer a straight line, but passes through a certain slope, which increases the length of the infiltration path of groundwater, which is equivalent to setting up an invisible barrier and greatly increasing the infiltration resistance.

[0030] Furthermore, in order to fix the water-stop screw 3, both the first main body 11 and the second main body 21 are provided with connecting holes 15. The water-stop screw 3 is fixedly connected to the connecting holes 15. The water-stop screw 3 is positioned through the connecting holes 15. The number of connecting holes 15 and the number of water-stop screw 3 are set accordingly. The specific position of the connecting holes 15 can be calculated and determined according to the dimensions of the base plate 1 and the standard plate 2.

[0031] Understandably, in order to prevent groundwater from flowing out through the connection hole 15 and entering the basement when it leaks, in some embodiments, the water-stop screw rod 3 also includes a sealing element. The sealing element is installed in the connection hole 15. On the one hand, it can fix the water-stop screw rod 3 more stably in the connection hole 15; on the other hand, it can seal the connection between the water-stop screw rod 3 and the foundation plate 1 or standard plate 2, preventing groundwater from entering the basement through the connection hole 15 when it leaks, thus causing water seepage in the basement.

[0032] To ensure the water-stopping effect of the water-stopping screw rod 3, in some embodiments, the water-stopping screw rod 3 also includes a water-stopping steel plate 31. The water-stopping steel plate 31 is installed in the middle of the water-stopping screw rod 3. By setting the water-stopping steel plate 31, on the one hand, the seepage path of groundwater can be changed, the seepage path of groundwater can be increased, and the water pressure of groundwater can be reduced, so that groundwater can no longer seep inward; on the other hand, the water-stopping steel plate 31 is cast into the wall and can act as a reinforcing rod, increasing the strength of the entire basement exterior wall 10 and ensuring the quality of the basement.

[0033] Understandably, multiple water-stop steel plates 31 can be installed and arranged sequentially on the water-stop screw 3, which can change the seepage path of groundwater multiple times, thereby preventing groundwater seepage.

[0034] In addition, the water-stop steel plate 31 is welded to the water-stop screw rod 3, and the welding method is full welding, which ensures the strength of the water-stop steel plate 31 and also prevents groundwater from seeping through the weld point between the water-stop steel plate 31 and the water-stop screw rod 3.

[0035] Understandably, in order to facilitate the pouring of the post-pouring strip water-stop system for the basement exterior wall 10, the post-pouring strip water-stop system for the basement exterior wall 10 also includes a formwork 4. The formwork 4 is installed on the other side of the basement exterior wall 10 and connected to the water-stop bolt 3. The formwork 4 is used to form a temporary closed structure together with the foundation slab 1 and the standard slab 2 to facilitate subsequent pouring. Specifically, the formwork 4 can be a wire mesh formwork or a multi-layer timber formwork.

[0036] Furthermore, in order to facilitate the subsequent design and construction of the basement structure, in some embodiments, the template 4 is set parallel to the standard plate 2, which can ensure that the area with the post-pouring strip water-stop system is relatively flat and not easily damaged by accidental bumps, thereby affecting the water-proofing effect of the post-pouring strip water-stop system of the entire basement exterior wall 10.

[0037] To ensure a stable connection between the template 4 and the base plate 1 or the standard plate 2, in some embodiments, the water-stop screw 3 further includes a mounting buckle 32. The mounting buckle 32 is connected to the template 4 and the template 4 is fixed by the mounting buckle 32. Specifically, the mounting buckle 32 also includes a tightening bolt. By tightening the bolt, the position of the mounting buckle 32 is adjusted to ensure the stable fixation between the template 4 and the base plate 1 and the standard plate 2, and to ensure that the distance between them is close, so as to reduce the error.

[0038] This invention provides a method for constructing a water-stopping system for the post-cast strip of a basement exterior wall 10, applicable to the aforementioned water-stopping system for the post-cast strip of the basement exterior wall 10, comprising: Step S1: Obtain the dimensions of the basement's exterior wall structure and hoist the foundation plate 1 to fit one side of the exterior wall structure.

[0039] In some application scenarios, when designing the post-cast strip water-stopping system for the basement exterior wall 10, it is necessary to select a base plate 1 and a standard plate 2 of appropriate size according to the actual dimensions of the basement exterior wall 10. The base plate 1 is placed at the bottom of the edge of the exterior wall to serve as a base plate to support the other standard plates 2.

[0040] Step S2: The hoisting template 4 is installed on the other side of the external wall structure, and the foundation plate 1 and template 4 are connected by the water-stop bolts 3.

[0041] In some application scenarios, the template 4 is installed on the other side of the basement exterior wall structure. The position and number of water-stop bolts 3 are calculated, and the template 4 and the foundation plate 1 are fixed by the water-stop bolts 3.

[0042] Step S3: Hoist the standard plate 2 and connect the second connecting part 23 of the standard plate 2 to the mounting part 12 of the base plate 1. Use the water-stop screw 3 to connect the standard plate 2 and the template 4.

[0043] In some application scenarios, the standard plate 2 is lifted up in sequence and assembled with the base plate 1 and other standard plates 2. That is, the first limiting groove 14 is engaged with the limiting block 24, and the mounting groove 25 is engaged with the first mounting block 13. The double fixing is used to achieve a stable connection between the standard plate 2 and the base plate 1. The position and number of water-stop screws 3 are calculated, and the standard plate 2 and the template 4 are connected by the water-stop screws 3.

[0044] Step S4: Hoist the standard panels 2 one by one, and use the water-stop screws 3 to connect the standard panels 2 and the template 4 until the top of the standard panels 2 is higher than the top of the external wall structure.

[0045] In some application scenarios, to ensure the waterproofing effect of the post-cast strip waterstop system of the entire basement exterior wall 10, multiple standard plates 2 are stacked together until the top of the standard plate 2 is higher than the top of the exterior wall structure. When two standard plates 2 are connected, the second mounting block 26 engages with the mounting groove 25, and the second limiting groove 27 engages with the limiting block 24 to complete the connection. Waterstop bolts 3 are then used to fix it to the formwork 4 to ensure the stability of the post-cast strip waterstop system of the entire basement exterior wall 10.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
