Description

Technical Field

[0001] This application belongs to the technical field of building waterproofing treatment, specifically relating to a waterproof structure consisting of prefabricated waterproof components and a replacement support plate. Background Technology

[0002] In basement construction, the replacement support strip is a crucial component used for temporary load transfer during structural transitions. As the main structure is constructed from bottom to top, the existing internal supports need to be removed layer by layer. Simultaneously, the water and soil pressure on the retaining structure needs to be gradually transferred to the newly completed main structure. Therefore, replacement support strips are installed before the removal of the internal supports to continue supporting the retaining structure. One end of the replacement support strip connects to the basement exterior wall of the main structure, and the other end connects to the retaining structure. The presence of the replacement support strip can cause discontinuity in the main waterproofing structure of the basement exterior wall, creating a weak point in the building's waterproofing. Utility Model Content

[0003] The purpose of this application is to provide a waterproof structure consisting of prefabricated waterproof components and replacement support strips, which aims to improve the continuity of the main waterproof structure of the basement exterior wall.

[0004] To achieve the above objectives, this application provides a waterproof prefabricated component, comprising: A waterproof substrate, wherein a hollow inner ring is formed at the center of the waterproof substrate, and the outer dimension of the waterproof substrate is larger than the outer dimension of the cross-section of the support strip; the outer dimension of the hollow inner ring is smaller than the outer dimension of the cross-section of the support strip and is used to be fitted onto the reinforcing steel skeleton of the support strip; and, A reinforcing layer is disposed on the top and bottom surfaces of the waterproof substrate and arranged around the periphery of the hollow inner ring. The reinforcing layer is used to connect with the concrete protective layer of the replacement support plate.

[0005] In some embodiments, the waterproof prefabricated component further includes a self-adhesive layer covering the top and bottom surfaces of the waterproof substrate and arranged around the periphery of the inner ring hollow portion, and the reinforcing layer is disposed on the surface of the self-adhesive layer.

[0010] In some embodiments, the waterproof substrate is a thermoplastic polyolefin component or a polyvinyl chloride component, and the adhesive layer is a hot melt adhesive material component.

[0011] In some embodiments, the waterproof substrate extends beyond the reinforcing layer by a length greater than 8 cm.

[0012] In some embodiments, the reinforcing layer is a sand layer or a plastic mesh.

[0013] Another aspect of this application provides a waterproof structure for a replacement support plate, including the aforementioned waterproof prefabricated component.

[0014] In some embodiments, the waterproof structure further includes waterproof mortar filling the hollow portion of the inner ring.

[0015] In some embodiments, the waterproof structure further includes: A coating layer is applied to the outer surface of the concrete protective layer and is located between the waterproof precast component and the basement exterior wall. A roll layer is applied over the coating layer.

[0020] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] The following description, with reference to the accompanying drawings, outlines the terminology of the waterproof prefabricated component 10 and the waterproof structure 100 of the replacement support plate according to this application.

[0022] like Figures 1 to 6 As shown, a specific embodiment of this application provides a waterproof precast component 10, including a waterproof substrate 1 and a reinforcing layer 3. The waterproof substrate 1 has an inner ring hollow portion 2 formed at its center, and the outer dimensions of the waterproof substrate 1 are larger than the outer dimensions of the cross-section of the replacement support plate 200. The outer dimensions of the inner ring hollow portion 2 are smaller than the outer dimensions of the cross-section of the replacement support plate 200 and are used to be fitted onto the steel reinforcement skeleton of the replacement support plate 200. The reinforcing layer 3 is disposed on the top and bottom surfaces of the waterproof substrate 1 and arranged around the outer periphery of the inner ring hollow portion 2. The reinforcing layer 3 is used to connect with the concrete protective layer of the replacement support plate 200.

[0023] The replacement support strip 200 is a key component used to support the temporary load transfer during structural transition. One end of it connects to the basement exterior wall 300 of the main structure, and the other end connects to the enclosure structure. The basement exterior wall 300 requires the application of a main waterproof membrane for building waterproofing. At the replacement support strip 200, the main waterproof membrane is extended onto the surface of the replacement support strip 200 and integrated with the waterproof substrate 1 to complete the continuity of the main waterproof structure 100 of the basement exterior wall 300, thereby improving the waterproofing effect.

[0024] Meanwhile, by setting a reinforcing layer 3, the waterproof precast component 10 is connected to the concrete protective layer of the replacement support plate 200 to form a physical mortise and tenon integrated structure, thereby avoiding the formation of water seepage gaps and improving the waterproof effect.

[0025] Specifically, the precast waterproof component 10 is placed at any cross-section of the support strip 200, preferably in the middle position, i.e., the position with the least shear force, to reduce the impact of the precast waterproof component 10 on the mechanical properties of the support strip 200. In fact, the waterproof substrate 1 only cuts off the concrete protective layer and has a very small impact on the mechanical properties of the support strip 200; the steel reinforcement and core concrete of the support strip 200 are the main components that transmit the force. After the concrete of the support strip 200 reaches the strength standard, the waterproof substrate 1 is folded towards the basement exterior wall 300 and connected to the splice of the main waterproof membrane to form a continuous main waterproof structure 100, thereby improving the waterproofing effect.

[0026] Furthermore, even if the portion of the replacement support strip 200 located between the waterproof precast component 10 and the enclosure structure cracks due to settlement or deformation, the concrete protective layer can be cut off by the waterproof substrate 1 to prevent rainwater from entering the interior of the main waterproof membrane through the cracks, thereby improving the waterproofing effect.

[0027] like Figures 1 to 3 As shown, in the first embodiment of this application, the waterproof prefabricated component 10 further includes a self-adhesive layer 4, which covers the top and bottom surfaces of the waterproof substrate 1 and is arranged around the periphery of the inner ring hollow portion 2. A reinforcing layer 3 is disposed on the surface of the self-adhesive layer 4. The self-adhesive layer 4 is used to adhere to the main waterproof membrane to strengthen the connection between the waterproof prefabricated component 10 and the main waterproof membrane, thereby improving the waterproof effect.

[0028] Furthermore, a release membrane 5 is provided on the surface of the self-adhesive layer 4. The release membrane 5 is arranged around the periphery of the reinforcing layer 3. The release membrane 5 is used to protect the self-adhesive layer 4 from being affected by impurities such as concrete and dust, so as to ensure the tightness of the connection between the self-adhesive layer 4 and the main waterproof membrane, thereby improving the reliability of the waterproof prefabricated component 10.

[0029] The waterproof prefabricated component 10 provided in the first embodiment of this application includes a waterproof substrate 1, a self-adhesive layer 4 covering the surface of the waterproof substrate 1, a reinforcing layer 3 covering the self-adhesive layer 4 and relatively close to the inner ring hollow portion 2, and a release membrane 5 covering the self-adhesive layer 4 and relatively far away from the inner ring hollow portion 2. The outer edge of the self-adhesive layer 4 is flush with the outer edge of the waterproof substrate 1.

[0030] Specifically, the waterproof prefabricated components 10 are divided into styrene-butadiene-styrene (SBS) modified bitumen rolls and self-adhesive rolls. In the SBS modified bitumen roll form, the waterproof substrate 1 is made of polyester fiber (base fabric), the self-adhesive layer 4 is made of bitumen adhesive, and the release film 5 is an anti-sticking release film. In the self-adhesive roll form, the waterproof substrate 1 is made of polyester fiber (base fabric), the self-adhesive layer 4 is made of bitumen adhesive or non-bitumen-based adhesive, and the release film 5 is a release film.

[0031] Regarding the connection between the waterproof prefabricated component 10 and the main waterproof membrane provided in the first embodiment of this application, the waterproof prefabricated component 10 in the form of SBS modified bitumen membrane is directly connected by hot-melt overlap, while the waterproof prefabricated component 10 in the form of self-adhesive membrane is directly pasted by tearing off the release liner.

[0032] In the second embodiment of this application, an adhesive layer 6 is provided between the reinforcing layer 3 and the waterproof substrate 1. The adhesive layer 6 is used to tightly connect the reinforcing layer 3 to the surface of the waterproof substrate 1, so as to avoid the reinforcing layer 3 falling off and affecting the tightness of the connection between the waterproof precast component 10 and the concrete protective layer, thereby improving the reliability of the waterproof precast component 10.

[0033] like Figures 4 to 6 As shown, the waterproof prefabricated component 10 provided in the second embodiment of this application includes a waterproof substrate 1 and a reinforcing layer 3 that is bonded to the surface of the waterproof substrate 1 by an adhesive layer 6. The waterproof substrate 1 extends beyond the reinforcing layer 3 and the extension length is greater than 8cm.

[0034] Specifically, the waterproof prefabricated component 10 is divided into thermoplastic polyolefin (TPO) roll material and polyvinyl chloride (PVC) roll material. In the TPO roll material form, the waterproof substrate 1 is made of thermoplastic polyolefin material, the self-adhesive layer 4 is made of hot melt adhesive material, and the adhesive layer 6 is made of hot melt adhesive material. In the PVC roll material form, the waterproof substrate 1 is made of polyvinyl chloride material, the self-adhesive layer 4 is made of hot melt adhesive material, and the adhesive layer 6 is made of hot melt adhesive material.

[0035] Regarding the connection between the waterproof prefabricated component and the main waterproof membrane provided in the second embodiment of this application, due to the physical properties of TPO membrane and PVC membrane, hot air welding is required for connection. Therefore, the length of the waterproof substrate 1 extending beyond the reinforcing layer 3 is greater than 8cm to meet the connection length requirements of hot air welding.

[0036] Those skilled in the art will understand that the materials of each layer of the waterproof prefabricated component 10 in this application are not limited to the first and second embodiments described above, but can also be other materials commonly used in waterproof membranes, and other structural forms should also fall within the protection scope of this application. It is only necessary to ensure that the form of the waterproof prefabricated component 10 is the same as that of the main waterproof membrane, so as to facilitate the connection between the waterproof prefabricated component 10 and the main waterproof membrane and the overall integrity after the connection.

[0037] In some embodiments, the inner ring hollow portion 2 of the waterproof substrate 1 is larger than the size of the reinforcing steel skeleton of the replacement support strip 200, so that the waterproof substrate 1 can be fitted onto the reinforcing steel skeleton; the reinforcing layer 3 is arranged around the periphery of the inner ring hollow portion 2, and the distance between the inner edge and the outer edge of the reinforcing layer 3 is less than the thickness of the concrete protective layer of the replacement support strip 200, so that the waterproof substrate 1 is tightly connected to the thickness of the concrete protective layer; the self-adhesive layer 4 is arranged around the periphery of the reinforcing layer 3, and the distance between the inner edge and the outer edge of the self-adhesive layer 4 is greater than 15cm, so that the self-adhesive layer 4 can be folded over and overlap with the main waterproof membrane for a sufficient length.

[0038] It should be noted that the dimensions of the waterproof precast component 10 in the specific embodiments of this application are determined based on the steel reinforcement skeleton, cross-sectional size, and concrete protective layer thickness of the replacement support plate 200.

[0039] like Figure 7 As shown, a specific embodiment of this application provides a waterproof structure 100 for a replacement support plate 200, including the waterproof prefabricated component 10 as described above. Since the waterproof structure 100 of the replacement support plate 200 adopts all embodiments of the above-described waterproof prefabricated component 10, the waterproof structure 100 of the replacement support plate 200 has all the beneficial effects brought about by all embodiments of the waterproof prefabricated component 10.

[0040] In some embodiments, the waterproof structure 100 further includes waterproof mortar 20 filled within the hollow portion 2 of the inner ring. After the waterproof substrate 1 is fitted onto the reinforcing steel frame of the support strip 200, the hollow portion 2 of the inner ring is filled with waterproof mortar 20 to cut off the core concrete of the support strip 200. This allows the waterproof mortar 20 and the waterproof precast component 10 to cut off the concrete portion of the support strip 200. Even if cracks appear in the portion of the support strip 200 located between the waterproof precast component 10 and the enclosure structure due to settlement or deformation, penetrating to the core concrete, rainwater can be prevented from entering the interior of the main waterproof membrane through the cracks, thereby improving the waterproofing effect.

[0041] Specifically, the waterproof precast component 10 is first set on the steel reinforcement skeleton of the replacement support plate 200, then the formwork is erected in the hollow part 2 of the inner ring, and then the waterproof mortar 20 is poured. After the waterproof mortar 20 has initially set, the formwork is removed, and finally the formwork is erected again to pour the concrete of the replacement support plate 200.

[0042] In some embodiments, the waterproof structure 100 further includes a coating layer 40 and a roll material layer 30. The coating layer 40 covers the outer surface of the concrete protective layer and is located between the waterproof precast component 10 and the basement exterior wall 300. The roll material layer 30 covers the coating layer 40, with one end of the roll material layer 30 connected to the main waterproof roll material on the basement exterior wall 300, and the other end of the roll material layer 30 being wrapped by the waterproof substrate 1.

[0043] In fact, the roll layer 30 is the end of the main waterproof roll. The self-adhesive layer 4 of the waterproof prefabricated component 10 is folded towards the basement exterior wall 300 and connected to the roll layer 30, so that the waterproof prefabricated component 10 and the roll layer 30 form an integral whole, thereby improving the integrity of the waterproof prefabricated component 10 and the main waterproof roll, and thus improving the waterproof effect.

[0044] It should be noted that when using thermoplastic polyolefin rolls as the main waterproofing membrane and connecting them with thermoplastic polyolefin components as the waterproofing base layer, the portion of the waterproofing base layer extending beyond the self-adhesive layer 4 needs to be welded to the main waterproofing membrane to make the waterproofing prefabricated component 10 and the roll layer 30 form an integral whole.

[0045] In this application, the waterproof structure 100 of the replacement support plate 200 of the waterproof precast component 10 provided by the specific embodiment of this application can not only be integrated with the main waterproof membrane, but also intercept and seal the concrete part of the replacement support plate 200, thereby ensuring that the interior of the main waterproof membrane is not affected by external water sources and thus its waterproof performance is not affected. At the same time, the waterproof structure 100 is also easy to construct, requiring only pre-embedding during the process of steel bar binding, without the need for subsequent treatment, which helps to save construction time. Furthermore, the size of the waterproof precast component 10 can be customized according to the size of the replacement support plate 200, and the material of the waterproof precast component 10 can be customized according to the material of the main waterproof membrane, which has good adaptability and is conducive to application in actual production.
