[0022] During the waterproofing construction of building projects, the waterproofing of the parapet wall of the roof needs to extend 250mm upwards. In the traditional construction process, the conventional waterproofing structure involves adding a metal strip and cover plate at a height of 250mm on the parapet wall to cover the waterproofing material and prevent rainwater from entering between the waterproofing material and the wall. The specific construction process is relatively complex because there are many installation structures, and the waterproofing seal after the installation structure is also considered. At the same time, the metal strip and cover plate are exposed on the outside of the wall, and after long-term use, the sealing quality is difficult to guarantee, and the aesthetics are also poor.

[0023] This utility model proposes a waterproof wall structure to solve the above problems.

[0024] Please see Figures 1 to 2 In one embodiment of this utility model, the waterproof wall structure 100 includes a wall body 1 and a waterproof component 2. The wall body 1 includes a floor slab portion 11 and a vertical wall portion 12. The vertical wall portion 12 is disposed on the floor slab portion 11, and a connection area is formed at the contact position between the vertical wall portion 12 and the floor slab portion 11. The vertical end face of the vertical wall portion 12 is recessed inward to form a groove portion 121, and the groove portion 121 extends along the length direction of the vertical wall portion 12. The waterproof component 2 includes a waterproof membrane 21 and a sealing and filling structure 22. The waterproof membrane 21 is laid on a portion of the wall surface on the same side of the floor slab portion 11 and the vertical wall portion 12, and covers the outside of the connection area. One end of the waterproof membrane 21 corresponding to the vertical wall portion 12 is fixed in the groove portion 121, and the sealing and filling structure 22 fills the upward end of the waterproof membrane 21 in the groove portion 121.

[0025] The specific structure of the wall in the above embodiments can be referred to Figure 1Its structure is primarily designed for the parapet wall structure on the roof. Correspondingly, the floor slab portion 11 corresponds to the roof plan structure, and the vertical wall portion 12 corresponds to the parapet wall structure. The parapet wall structure mainly serves a safety protection function, while also enhancing the aesthetics of the roof. Generally, the parapet wall is formed by concrete pouring, and the end in contact with the floor slab structure needs to meet relevant waterproofing requirements. Therefore, the conventional construction process includes not only pouring the vertical wall portion 12 but also constructing a waterproofing structure between the vertical wall portion 12 and the floor slab portion 11.

[0026] Traditional waterproof structures such as Figure 2 As shown, waterproof material is pre-laid on the same side of the vertical wall portion 12 and the floor slab portion 11. After the waterproof material is laid, its end corresponding to the vertical wall portion 12 is vertically positioned. To prevent rainwater from seeping in through the gap between the waterproof material and the vertical wall portion 12, a shielding element is usually installed on the vertical wall portion 12 above the end corresponding to the waterproof material. Figure 2 As shown, one end of the shielding member extends downward to the outside of the waterproof material, thereby preventing rainwater from entering the gap between the waterproof material and the vertical wall portion 12.

[0027] The above traditional methods still have some problems. For example, after the shielding component is installed, the installation end 212 of the shielding component needs to be filled with waterproof material to seal the installation gaps, which is a relatively cumbersome construction process. Furthermore, both the shielding component and the sealant are located on the outside of the vertical wall 12, making them susceptible to deterioration in connection performance due to wind and sun exposure, resulting in frequent maintenance. In addition, the shielding component's protruding location on the outside of the vertical wall 12 is not conducive to improving the overall aesthetics of the vertical wall 12 and fails to meet the aesthetic requirements of the parapet wall.

[0028] Considering the above problems, in the above embodiment, the waterproof component 2 is set as an embedded waterproof structure. Specifically, a recessed groove 121 is provided on one side of the vertical wall portion 12, and the groove 121 extends along the length direction of the vertical wall portion 12. It is conceivable that when the vertical wall portion 12 forms a bent structure, the groove 121 corresponds to the specific extension direction of the vertical wall portion 12. Preferably, the groove 121 is formed during the pouring of the vertical wall portion 12 to avoid affecting the overall strength of the vertical wall portion 12 through later excavation and to avoid adding extra steps. When actually laying the waterproof component 2, the waterproof membrane 21 is first laid on the same side of the vertical wall portion 12 and the floor slab portion 11, such as... Figure 1As shown, the bending position of the waterproof membrane 21 is set as close as possible to the connecting area to fit the two vertical wall structures as closely as possible. When finishing the edge of the waterproof membrane 21, one end of the waterproof membrane 21 corresponding to the vertical wall portion 12 can be bent into the groove portion 121, and then the end of the waterproof membrane 21 can be fixed in the groove portion 121 by the fixing structure 7, such as a screw structure. Finally, the filling structure is filled above the folded edge of the waterproof membrane 21 before the end of the waterproof membrane 21 and the inner wall of the groove portion 121. It should be noted that when filling, the filling structure can fill the entire cavity structure above the waterproof membrane 21, but the filling material is all located in the groove portion 121, so that the opening of the groove portion 121 is kept in contact with the wall surface of the vertical wall portion 12 as much as possible. This improves the overall aesthetics of the vertical wall section 12. During later processing, a uniform color can be applied to the wall surface of the vertical wall section 12. Since the wall surface at the opening of the entire groove section 121 is relatively flat, the entire wall surface of the vertical wall section 12 can present a better appearance.

[0029] Furthermore, by using the aforementioned concealed sealing method to seal the waterproof membrane 21, and because the end of the waterproof membrane 21 is located within the groove 121 and has a lateral extension, rainwater is unlikely to enter between the end of the waterproof membrane 21 and the wall surface of the vertical wall portion 12 during downward flow. Moreover, the filling structure further enhances the waterproofness of the entire sealing structure. Compared to traditional sealing structures, the recessed sealing structure in the above embodiment not only provides better waterproofing but also effectively addresses aesthetic requirements.

[0030] In order to improve the fixing effect of the waterproof membrane 21 when fixing the end of the waterproof membrane 21, in one embodiment of the present invention, a support part 3 is also provided in the groove 121. The support part 3 has an inclined support surface, and one end of the waterproof membrane 21 is fixed to the support surface; wherein, the inclination direction of the support surface is inclined from the groove opening of the groove 121 towards its groove bottom, and from bottom to top.

[0031] The support portion 3 is provided within the groove 121 to facilitate the fixing of one end of the waterproof membrane 21. The support portion 3 can be made of wood. Specifically, during fixing, one end of the waterproof membrane 21 is pressed down and fixed to the inclined support surface of the support portion 3. Then, wooden nails are used to fix one end of the waterproof membrane 21 to the support portion 3, thus giving one end of the waterproof membrane 21 a horizontal extension, which not only aids in waterproofing but also improves its fixing effect. Furthermore, the inclined direction of the support surface in the above structure, from the opening of the groove 121 towards its bottom and from bottom to top, is designed to ensure a larger relative area of ​​the support surface corresponding to the opening of the groove 121, making it easier to fix one end of the waterproof membrane 21 through the groove 121.

[0032] During the edge finishing process, one end of the waterproof membrane 21 and the filling structure are both located within the groove 121, not protruding from the vertical wall surface of the vertical wall portion 12. Specifically, the waterproof membrane 21 has an installation end 212 that connects to the support portion 3, and a sealing area is formed within the groove 121 above the installation end 212, with the sealing filling structure 22 located within the sealing area. This method improves the aesthetic appearance of the vertical wall portion 12 and provides a better foundation for subsequent wall beautification treatment.

[0033] The sealing and filling structure 22 can be selected from many materials, such as expanding foam, waterproof mortar, and structural adhesive. The appropriate material can be chosen based on the specific production conditions.

[0034] Regarding the specific location of the groove 121, during the construction process, the waterproofing of the parapet wall is required to reach a height of 250mm, so the distance from the bottom of the groove 121 to the floor slab 11 is at least 250mm.

[0035] Regarding the specific shape of the groove portion 121, in one embodiment of this utility model, the cross-sectional shape of the groove portion 121 is set to a square cross-section, the groove depth of the groove portion 121 is Ld, 250mm≤Ld≤350mm, and the groove width of the groove portion 121 is Lw, 450mm≤Ld≤550mm.

[0036] Within the above parameter range, during actual construction, it is preferable to set the groove depth to 300mm and the groove width to 500mm. By taking the middle value, the groove portion 121 can be set with reference to the middle value during specific construction, which can effectively avoid excessive deviation. At the same time, setting the groove portion 121 within the above vertical range will not make the groove too large, which will not affect the overall strength of the vertical wall portion 12, and will also facilitate the edge finishing construction of one end of the waterproof membrane 21.

[0037] It is conceivable that the groove 121 is usually formed by casting. The advantage of a square groove structure is that the mold corresponding to the groove 121 can be better erected; the flat template not only facilitates fixing but also makes demolding easier.

[0038] In one embodiment of this utility model, in order to improve the waterproofness of the connection area, the waterproof membrane 21 is thickened at the location corresponding to the connection area. Specifically, the waterproof membrane 21 includes a membrane body, and an additional layer 211 is formed on the membrane body corresponding to the location of the connection area to increase the thickness of the waterproof material at the connection area.

[0039] Since the connection area is the main protection area against water seepage, strengthening the waterproofing of this part in the above manner can effectively improve the service life of the entire waterproof structure.

[0040] This utility model also includes a template structure 200, which is applied to the waterproof wall structure 100. Specifically, the template structure 200 can be used for the casting and forming of the vertical wall portion 12, and can simultaneously form the groove portion 121. During the actual construction process, the template structure 200 can effectively improve construction efficiency. Specifically, the template structure 200 includes two sets of keel structures, template components, and multiple channel steel structures 6. The two sets of keel structures are spaced apart in the horizontal direction; the template assembly includes multiple template bodies 5, which are all installed on the two sets of keel structures and are interconnected to form a supporting wall 52. A casting area 53 is formed between the two supporting wall surfaces 52 to form the vertical wall portion 12; multiple channel steel structures 6 are installed on the multiple template bodies 5 and are connected end to end in the length direction of the vertical wall portion 12. The open end of the channel steel structure 6 is fixedly connected to the template body 5, and the bottom end of the channel steel structure 6 is located in the casting area 53 to form the groove portion 121.

[0041] In actual construction, the two sets of keel structures are first set up opposite each other on a horizontal plane to form the installation foundation of the entire template structure 200. During installation, it is necessary to ensure that the spacing between the two sets of keel structures is relatively uniform. Then, multiple template bodies 5 are installed on the opposite side of the two sets of keel structures. The template bodies 5 are made of wood and can be fixed by binding or nailing during installation. After the multiple template bodies 5 are fixed on the two sets of keel components, two opposing support walls 52 are formed. The concrete pouring area 53 is located between the two support walls 52, which is also the pouring space for the vertical wall portion 12. In this embodiment, the aforementioned groove portion 121 is formed integrally during the pouring process. To facilitate template erection, this embodiment uses an integrated channel steel instead of the traditional multi-template structure 200. During the actual erection of the template, it is only necessary to integrate the channel steel and the corresponding template body 5 to form the mold shape corresponding to the groove portion 121. This effectively improves the convenience of the template erection process. Specifically, the open end of the channel steel structure 6 is fixedly connected to the template body 5, and the bottom end of the channel steel structure 6 is located in the pouring area 53. After the concrete is poured in one piece and the formwork is removed, the vertical wall part 12 structure with the groove part 121 can be formed.

[0042] Considering the considerable length of the vertical wall section 12, its extension direction may need to be altered. Using a single, integrated channel steel structure 6 would be unsuitable for practical applications. Therefore, it is preferable to configure the channel steel structure 6 as multiple assembly units with fixed lengths. The specific extension length of each unit can be set according to actual needs. During assembly, adjacent channel steel structures 6 are connected via corresponding assembly structures. Specifically, the two ends of the channel steel structure 6 along its length are connecting ends, and the connecting ends of adjacent channel steel structures 6 are connected by a fixing structure 7.

[0043] The connecting end is provided with a mounting hole 61, which is through-hole located at the bottom of the channel steel structure 6. The fixing structure 7 includes a connecting piece 71 and two connecting bolts. The connecting piece 71 is provided with two fixing holes 711, the distance between the two fixing holes 711 corresponding to the spacing between the mounting holes 61 on the two adjacent mounting ends 212. Two connecting screws 72 pass through the fixing holes 711 and the mounting holes 61, and the through-hole end of the screw passes through the casting area 53 and connects with the template body 5.

[0044] like Figure 3 , Figure 4 , Figure 5 As shown, during actual installation, the two fixing holes 711 on the connecting piece 71 are respectively aligned with the mounting holes 61 on the two adjacent mounting ends 212. Then, the two connecting screws 72 are respectively inserted into the two sets of hole structures. Fixing the inserted ends of the connecting screws 72 to the template unit provides a good fixing effect, thereby ensuring the installation stability between the two channel steel structures 6. Multiple channel steel structures 6 can be installed together in this way to suit the construction of different vertical wall sections 12.

[0045] To improve the stability of the channel steel during installation, thereby enhancing the overall strength of the entire template structure 200, this embodiment modifies the specific structure of the channel steel to better establish a fixed connection with the adjacent template body 5. Specifically, as follows... Figure 3 , Figure 4 and Figure 5 As shown, the two ends of the channel steel structure 6 in the length direction are through-connected to form two supporting cavity walls 63 in the width direction. Each of the two supporting cavity walls 63 has a through groove 62 extending along its length direction near the opening of the channel steel structure 6, for one end of the template body 5 to pass through.

[0046] Furthermore, in order to facilitate the connection between the template body 5 and the channel steel structure 6, one end of the template body 5 located above or below the channel steel structure 6 has an insertion part 51 protruding outward. The insertion part 51 is provided through the two through slots 62, and the length of the insertion part 51 corresponds to the length of the through slot 62.

[0047] During actual installation, the mold body with the insertion part 51 is simply installed above or below the channel steel structure 6, and the insertion part 51 passes through the two through slots 62 in the vertical direction, thus connecting the channel steel structure 6 and the template body 5 into one unit. Furthermore, the limiting effect of the insertion part 51 effectively prevents the channel steel structure 6 from swaying, further improving the overall stability of the entire template structure 200. Moreover, by fixing the channel steel structure 6 in the above manner, complex fixing operations are eliminated during construction, greatly improving convenience.

[0048] The aforementioned template structure 200 is reusable, including the channel steel structure 6, which also helps to reduce construction costs.

[0049] like Figure 5 , Figure 6 and Figure 7As shown, multiple connecting structures 8 are provided between the two supporting wall surfaces 52; the connecting structures 8 ensure the stability of the distance between the two supporting wall surfaces 52. During the grouting process, the pressure gradually increases, which also ensures the consistency of the thickness of the vertical wall portion 12 after molding. The connecting structure 8 can be set as a screw structure, and its exposed end can be cut after the mold is removed. Alternatively, it can be set as a PVC sleeve, which can be directly retained in the vertical wall portion 12 after demolding.

[0050] The keel structure includes multiple steel pipe keels 4 spaced apart along the length of the vertical wall 12. The steel keel structure can provide better support during grouting, thereby minimizing the deformation of the wall structure.

[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
