DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and effect of the utility model more clear, definite, the following will be further described in detail with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

Therefore, the features with "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled persons in the art, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the utility model.

[0036] In the prior art, as shown in Figure 3 The corner code 600 and other fixing structures are used to lock the prefabricated outer wall panel and the beam, and the fixing structures such as the corner code 600 are deformed by stress over time, and the appearance is not good due to rust. Since the corner code 600 is embedded in the assembly groove at the corresponding beam position, it is difficult to replace, and it causes great difficulty in building maintenance.

[0037] Based on the above problems in the prior art, the utility model provides a novel connection and internal and external waterproof structure of a prefabricated outer wall panel, as shown in Figure 1 The novel connection and internal and external waterproof structure of the prefabricated outer wall panel comprises: a prefabricated wall panel 100, a first embedded part 200 is arranged in the prefabricated wall panel 100, the first embedded part 200 comprises a fixedly connected extension part 210 and a connecting part 220, the extension part 210 is arranged on the upper end of the prefabricated wall panel 100, and the connecting part 220 is arranged on one side of the prefabricated wall panel 100; a reverse ridge 300 matched with the extension part 210 is arranged on one side of the lower end of the prefabricated wall panel 100; a beam body 400, a second embedded part 410 is arranged in the beam body 400, and the connecting part 220 is fixedly connected with the second embedded part 410.

[0038] The utility model discloses a new type connection and inner and outer waterproof structure of prefabricated outer wall board, which is composed of a prefabricated wall plate 100 and a beam body 400.

[0039] In the above embodiment, as shown in Figure 1 The new type connection and inner and outer waterproof structure of prefabricated outer wall board of the utility model is composed of a prefabricated wall plate 100 and a beam body 400, and the prefabricated wall plate 100 in the embodiment comprises a first embedded part 200 arranged inside, the first embedded part 200 comprises a fixedly connected extension piece 210 and a connecting piece 220, specifically, the extension piece 210 protrudes from the upper end of the prefabricated wall plate 100 and is used for connecting the adjacent prefabricated wall plate 100 above, thereby avoiding the use of an angle code 600 for fixed connection; the connecting piece 220 protrudes from one side of the prefabricated wall plate 100 and is used for connecting the corresponding beam body 400 on one side, thereby avoiding the use of an angle code 600 for fixed connection.

[0040] In the embodiment, in order to realize the connection of the upper and lower adjacent prefabricated wall plates 100, a reverse ridge 300 matched with the extension piece 210 is arranged on one side of the lower end of the prefabricated wall plate 100, as shown in Figure 1 After the upper and lower adjacent prefabricated wall plates 100 are butted, the extension piece 210 of the lower prefabricated wall plate 100 extends into the reverse ridge 300 of the upper prefabricated wall plate 100, so that the extension piece 210 of the lower prefabricated wall plate 100 can be locked in the upper prefabricated wall plate 100 by pouring the reverse ridge 300, thereby realizing the effect of fixed installation; meanwhile, the second embedded part 410 is arranged in the beam body 400 in the embodiment, and when the prefabricated wall plate 100 is installed, the connecting piece 220 protruding from the prefabricated wall plate 100 is fixedly connected with the second embedded part 410 in the beam body 400, which can be used for structural positioning and realizes the effect of fixed connection of the beam and the prefabricated wall plate 100.

[0041] In this embodiment, the beam 400 is a cast-in-place beam. That is, during the actual construction process, the second embedded part 410 can be pre-arranged to predetermine the setting position of the beam 400 and connect it with the precast wall panel 100 in the adjacent position and other structures in the building. Then, it is produced by casting concrete on site using molds. On this basis, since the connector 220 in the precast wall panel 100 is fixedly connected to the second embedded part 410, a part of the connector 220 can be cast into the interior of the beam 400 after the casting is completed, thereby achieving the effect of fixed connection.

[0042] Furthermore, such as Figure 1 As shown, several butt joint grooves are provided on one side of the precast wall panel 100 corresponding to the beam 400. The butt joint grooves are recessed into the inside of the precast wall panel 100. Since the beam 400 is a cast-in-place beam, it can enter several butt joint grooves during casting. After the beam 400 is formed, it forms a locking structure with the precast wall panel 100. At the same time, since the connector 220 of the precast wall panel 100 is cast inside the beam 400, a connection effect of horizontal limiting and vertical locking can be formed. This can effectively prevent deformation and settlement at the joint between the beam 400 and the precast wall panel 100, and effectively improve the quality of building assembly.

[0043] In another possible embodiment of this utility model, such as Figure 1 As shown, the first embedded part 200 also includes an inner frame 230. The inner frame 230 is used to improve the structural strength of the precast wall panel 100, giving it a stronger resistance to lateral stress and better load-bearing capacity. In this embodiment, the inner frame 230 also has another function. In specific installation, the inner frame 230 and the extension part 210 are integrally formed, that is, the extension part 210 is actually an extension structure of the inner frame 230. When adjacent precast wall panels 100 are installed together, the extension part 210 and the inner frame 230 share the pressure and lateral stress, thus achieving a more stable installation effect. On the other hand, One end of the inner frame 230 protrudes into the interior of the reverse wall 300. When the upper and lower adjacent precast wall panels 100 are installed together, the extension 210 of the lower precast wall panel 100 enters the interior of the reverse wall 300 of the upper precast wall panel 100. At this time, the reverse wall 300 is hollowed out. Construction workers can connect the extension 210 to the protruding inner frame 230 in the reverse wall 300 by welding, metal binding or other methods, so as to achieve the effect of initial positioning and connection. After the reverse wall 300 is filled, the extension 210 of the lower precast wall panel 100 and the upper precast wall panel 100 form a whole, which can form a stable connection effect.

[0044] Furthermore, such as Figure 1As shown, the aforementioned filler 500 for filling the reverse wall 300 is provided inside the reverse wall 300. The filler 500 is specifically concrete or mortar with a fixing function. The filler 500 is initially in a liquid or fluid mixture state when poured. Construction workers can use a mold to seal the side of the reverse wall 300 and pour the filler 500 into the upper end of the reverse wall 300. After the filler 500 has completely solidified, the mold can be removed to seal the reverse wall 300 and further fix the aforementioned extension 210 and inner frame 230, thereby achieving the effect of completely fixing and connecting the upper and lower adjacent precast wall panels 100.

[0045] In this embodiment, to ensure that the process of injecting filler 500 into the inverted wall 300 is easy to operate and the subsequent molding is aesthetically pleasing, it is preferable to set the upper side of the inverted wall 300 at a predetermined angle. This provides a flow channel for the filler 500, facilitates the construction personnel to observe the filling status inside the inverted wall 300, and prevents the occurrence of empty areas after filling the inverted wall 300, thus ensuring the filling quality.

[0046] Based on the above embodiments, in another possible embodiment of this utility model, to prevent water from entering at the joint of adjacent precast wall panels 100, such as... Figure 1 As shown, a step portion 101 is protruding from the lower end of the precast wall panel 100 on the side opposite to the anti-reflector 300. The step portion 101 extends downward toward the lower end face of the precast wall panel 100, and the step portion 101 and the lower end face of the precast wall panel 100 are transitioned by a slope. Correspondingly, a relief groove 102 is recessed at the upper end of the precast wall panel 100 at the position corresponding to the step portion 101. The relief groove 102 is adapted to the shape of the step portion 101. When adjacent precast wall panels 100 are joined, the step portion 101 is fitted into the relief groove 102. When one side of the precast wall panel 100 is exposed to rain, snow or water immersion, since the lower end face of the precast wall panel 100 is above the joint of the step portion 101, water flow can be prevented from entering the joint of the adjacent precast wall panels 100, thereby avoiding water corrosion of building materials and improving the service life of the building.

[0047] More specifically, such as Figure 1 As shown, in actual installation, a predetermined distance can be set between the stepped portion 101 and the relief groove 102, and a sealing element 103 can be set between the stepped portion 101 and the relief groove 102. The sealing element 103 can be filled with PE rods and polyurethane sealant, or filled by setting tongue and groove and waterproof strip, so that the joint between the stepped portion 101 and the relief groove 102 has a better waterproof effect. Combined with the stepped structure formed by the lower end face of the precast wall panel 100 and the lower end face of the stepped portion 101, a double waterproof effect is formed.

[0048] In another possible embodiment of this utility model, such as Figure 1 As shown, the connector 220, inner frame 230, and extension 210 can be manufactured as a single piece. For ease of production, they can also be manufactured as separate structures, i.e., the inner frame 230 and extension 210 are integrally formed, and the connector 220 is an independent component that is fixedly connected to the inner frame 230. In this embodiment, the connector 220 is specifically composed of an integrally formed main body 223, a first end 221, and a second end 222. The main body 223 is wrapped inside the precast wall panel 100 and fixedly connected to the inner frame 230. The first end 221 and the second end 222 are actually the two ends of the main body 223, which protrude from the precast wall panel 100 in the specific setting. In this embodiment, the first end 221 and the second end 222 correspond to the upper and lower ends of the cross section of the beam 400, respectively, thereby forming a double connection effect at the ends of the beam 400 through the first end 221 and the second end 222.

[0049] In specific configurations, the first end 221 and the second end 222 can be bent toward each other (e.g., Figure 1 (As shown), or, based on the bending of the first end 221 and the second end 222 towards each other, a side bend is then performed (please refer to...). Figure 1 and Figure 2 The bent portions of the first end 221 and the second end 222 are wrapped around the second embedded part 410 to form a structural connection with the second embedded part 410. After the beam body 400 is cast and formed, the bent first end 221 and the second end 222 form an interlock with the inside of the beam body 400, which can effectively improve the bonding strength between the beam body 400 and the precast wall panel 100, improve the building quality, and eliminate the need to use corner brackets 600 for fixing.

[0050] In another embodiment of this utility model, the first end 221 can also be installed by inserting it into the upper side of the second embedded part 410. The advantage of this arrangement is that it is convenient to adjust the installation position of the first end 221 and the second embedded part 410 during the installation process, thereby facilitating the installation of the components.

[0051] In the above embodiments, both the first embedded part 200 and the second embedded part 410 are steel bars. During the production process of the precast wall, the construction personnel can adjust the specific shape and size of the first embedded part 200 according to the actual use requirements, and this application does not limit this. During the pouring process of the beam 400, the construction personnel can adjust the combination state of the second embedded part 410 and the connector 220 (such as the bending style of the first end 221 and the second end 222) according to the actual use requirements, and this application does not limit this.

[0052] Based on the above embodiments, the actual installation process of the novel connection and internal / external waterproof structure of the prefabricated exterior wall panel of this utility model is as follows:

[0053] like Figure 1 As shown, the precast wall panel 100 is hoisted to the corresponding position of the beam 400. During this process, the connector 220 in the precast wall panel 100 is connected to the second embedded part 410 in the beam 400. Then, the beam 400 is poured to fix the beam 400 and the precast wall panel 100 together.

[0054] Simultaneously, during the installation of adjacent precast wall panels 100, the upper precast wall panel 100 is hoisted above the corresponding lower precast wall panel 100, so that the extension 210 in the lower precast wall panel 100 corresponds to the anti-sill 300 of the upper precast wall panel 100, and the extension 210 is fixedly connected to the exposed inner frame 230 in the anti-sill 300. During the process, sealing elements 103 are arranged on the stepped portion 101 and the relief groove 102 of the upper and lower precast wall panels 100. After the arrangement is completed, a mold is used to seal one side of the anti-sill 300, and filler 500 is injected into the interior of the anti-sill 300. After the filler 500 is cured, the mold is removed, thus completing the docking of the upper and lower precast wall panels 100.

[0055] In summary, this utility model provides a novel connection and internal / external waterproofing structure for prefabricated exterior wall panels. This structure includes: a prefabricated wall panel with a first embedded part inside, comprising an extension and a connector for fixed connection. The extension protrudes from the upper end of the prefabricated wall panel, and the connector protrudes from one side of the prefabricated wall panel. A retaining wall adapted to the extension is provided on one side of the lower end of the prefabricated wall panel. A beam body with a second embedded part inside, and the connector is fixedly connected to the second embedded part. This utility model achieves connection between adjacent prefabricated wall panels by providing a retaining wall at the lower end and a protruding extension at the upper end. During assembly, the extensions of adjacent prefabricated wall panels extend into the retaining wall for fixation. By providing a protruding connector on one side of the corresponding beam body, which is fixedly connected to the second embedded part within the beam body during casting, the beam body is connected to the corresponding prefabricated wall panel. This avoids structural deformation and eliminates the need for additional connecting components, facilitating building maintenance and reducing assembly steps.

[0056] It should be understood that the application of this utility model is not limited to the examples above.
