Description

Technical Field

[0001] The present invention relates to the technical field of green buildings, and more particularly to a prefabricated wall panel for green building design. Background Art

[0002] As the concept of green building continues to develop and promote, prefabricated wall panels are increasingly being used in the construction industry due to their advantages such as efficient construction, energy conservation, and environmental protection. Prefabricated wall panels are manufactured in factories and then transported to the construction site for assembly and installation. This effectively reduces on-site wet work, reduces construction pollution, and improves construction efficiency, meeting the requirements of sustainable development in green buildings.

[0003] However, existing prefabricated wall panels for green building designs have numerous shortcomings in their joint structure. Traditional prefabricated wall panels lack stability when spliced ​​together, relying solely on simple plug-in or bolt connections. When subjected to external forces such as earthquakes and wind, these panels can easily loosen and shift, compromising the overall safety of the building structure. To address this, we propose a prefabricated wall panel for green building design. Summary of the Invention

[0004] The purpose of the present invention is to provide a prefabricated wall panel for green building design to solve the technical problem that the current prefabricated wall panels are poor in stability when spliced ​​and only rely on simple plug-in or bolt connections. When the building is affected by external forces such as earthquakes and wind, the wall panels are prone to loosening and displacement, affecting the overall safety of the building structure.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: a prefabricated wall panel for green building design, comprising a wall panel body, wherein opposite sides of the wall panel body are vertically provided with splicing grooves of the same size, a plurality of flush-positioned limit grooves are provided on the inner facing surfaces of the splicing groove on one side, and the cross-section of the limit groove is a right-angled triangle, and a splicing plug-in plate that plugs into the splicing groove is integrally formed inside the splicing groove on the other side, and the opposite sides of the splicing plug-in plate are installed with limit members that can be snap-fitted into the limit groove; Support members with the same length as the splicing plug-in board are integrally formed at both ends of the splicing groove provided with the limit groove, and positioning plug-ins for vertical plug-in limitation are movably installed at both ends of the splicing groove on both sides, and the support members are plugged into the positioning plug-in on the same side.

[0006] The present invention forms a basic splicing structure by cooperating the splicing grooves and splicing plug-ins provided on both sides of the wall panel body, and the clip-on design of the limit grooves and the limit members further enhances the stability after splicing. The extrusion force generated during the splicing process causes the two to fit together, effectively preventing the wall panel from shifting in the horizontal direction, and the cooperation of the support members and the positioning plug-ins can complete the vertical limitation of the wall panel body, further enhancing the splicing strength of the wall panel body. When the building is subjected to external forces such as earthquakes and wind, this clip-on structure can effectively limit the relative displacement between the wall panels. Compared with traditional simple plug-in or bolt connection, it greatly enhances the stability after splicing and significantly improves the overall safety of the building structure.

[0007] Preferably, the limiting member includes a base plate, and both sides of one side of the base plate are integrally formed with V-shaped spring pieces with ends facing away from each other, a limiting plate is fixedly arranged between the other ends of the V-shaped spring pieces on both sides, and the outer side surface of the limiting plate is constructed with an extrusion surface that fits the inclined surface of the limiting groove.

[0008] Preferably, the opposite sides of the splicing plug board are provided with several installation grooves for limiting the position of the base plate, the inner sides of the installation grooves are provided with several positioning holes, and the sides of the base plate away from the V-shaped spring sheet are integrally formed with several positioning blocks that are plugged into the positioning holes.

[0009] Preferably, the support member includes a support block, the side of the support block that fits the positioning plug-in is integrally formed with a first trapezoidal tenon, and the side of the support block that fits the splicing groove and is away from each other is integrally formed with a second trapezoidal tenon.

[0010] Preferably, the positioning plug-in comprises an insert block, a side of the insert block in contact with the support block is provided with a second mortise for engaging with the first tenon, and a plurality of positioning grooves are vertically provided on the opposite side of the insert block.

[0011] Preferably, both ends of the splicing groove on one side of the splicing plug board are provided with a first mortise for plugging with the second tenon, and both ends of the splicing groove on both sides are fixedly provided with a tough sealing rod on the facing surfaces, and the sealing rod is connected to the positioning groove.

[0012] Preferably, the vertical length of the positioning plug protruding from the wall panel body is the same as the vertical length of the support member, and the overall vertical length of the positioning plug is the same as the length between the splicing plug plate and the end of the wall panel body.

[0013] Preferably, a plurality of sealing strips with deformation elasticity are fixedly provided on the inner side surface of the splicing groove located on one side of the limiting groove, and a plurality of sealing connection grooves for engaging with the sealing strips are opened on the side of the splicing plug board away from the wall panel body.

[0014] Preferably, a skeleton is fixedly provided in the middle of the sealing strip, and the cross-section of the sealing strip is T-shaped.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention forms a basic splicing structure by cooperating the splicing grooves and splicing plug-ins set on both sides of the wall panel body, and the clip-on design of the limit grooves and the limit parts further enhances the stability after splicing. The extrusion force generated during the splicing process will cause the two to fit together, effectively preventing the wall panel from shifting in the horizontal direction, and the cooperation of the support parts and the positioning plug-ins can complete the vertical limitation of the wall panel body, further strengthening the splicing strength of the wall panel body. When the building is subjected to external forces such as earthquakes and wind, this clip-on structure can effectively limit the relative displacement between the wall panels. Compared with traditional simple plug-in or bolt connection, it greatly enhances the stability after splicing and significantly improves the overall safety of the building structure.

[0016] 2. The present invention also uses the elastic deformation ability of the V-shaped spring piece in the limiter so that the limit plate can automatically enter the installation groove when inserted into the splicing groove. When aligned with the limit groove, the extrusion surface of the limit plate can closely fit the inclined surface of the limit groove. The extrusion force generated during the splicing process will cause the two to fit together, effectively preventing the wall panel from shifting in the horizontal direction, and further improving the structural matching strength.

[0017] 3. The present invention also utilizes the support members and positioning plugs at both ends of the splicing slot to work in tandem. The first and second tenons of the support members engage with the second mortise of the positioning plug and the first mortise of the splicing slot, respectively, to form a stable support structure. Simultaneously, the positioning slots on the positioning plugs abut against the sealing rods, not only providing positioning but also further enhancing the connection strength at the wall panel joint, ensuring that the wall panels maintain precise positioning even under complex external forces, preventing loosening and misalignment.

[0018] 4. The combination of the sealing strip and the sealing connection groove, as well as the abutment of the sealing rod and the retaining groove, creates a multi-layered sealing structure. The central framework of the sealing strip enhances its structural strength and deformation recovery. Its T-shaped cross-section allows it to tightly fill the joint gap, effectively blocking the infiltration of rainwater and air, and improving the wall's waterproofing, thermal insulation, and soundproofing properties. This sealing design helps reduce building energy consumption and meets the energy-saving and environmental protection requirements of green buildings. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figures 1 to 11 As shown, the present invention relates to a prefabricated wall panel for green building design, comprising a wall panel main body 1, opposite sides of the wall panel main body 1 are vertically provided with splicing grooves 2 of the same size, the inner facing surfaces of the splicing groove 2 on one side are provided with a plurality of flush limiting grooves 201, and the cross-section of the limiting groove 201 is a right triangle, the interior of the splicing groove 2 on the other side is integrally formed with a splicing plug-in plate 3 that is plugged into the splicing groove 2, and the opposite sides of the splicing plug-in plate 3 are installed with limiting members 7 that can be snap-fitted with the limiting groove 201; one side of a wall panel main body 1 with a splicing plug-in plate 3 can be inserted into the interior of the splicing groove 2 set on another wall panel main body 1 to achieve a preliminary splicing effect, and the snap connection between the limiting groove 201 and the limiting member 7 can fix the splicing position between the two, thereby enhancing the stability of the splicing position.

[0022] At both ends of the splicing groove 2 with a limiting groove 201, support members 4 of the same length as the splicing plug-in board 3 are integrally formed, and positioning plug-ins 6 for vertical plug-in limiting are movably installed at both ends of the splicing grooves 2 on both sides, and the support members 4 are plugged into and connected with the positioning plug-in 6 on the same side; by installing the positioning plug-in 6 at the end position of the splicing groove 2, it can be kept flush with the end of the splicing groove 2 in the initial state without hindering the installation. After the installation position is fixed, it can be inserted into the reserved positioning groove position by moving up and down. When the support member 4 on the other wall panel body 1 is inserted into the interior of the splicing groove 2 as the splicing plug-in 3 is inserted, it can be combined with the positioning plug-in 6 to achieve the effect of horizontal and vertical limitation, thereby further enhancing the stability of the installation of the wall panel body 1.

[0023] In an embodiment of the present invention, the limiting member 7 includes a base plate 701, and V-shaped spring pieces 702 with ends facing each other are integrally formed on both sides of one side of the base plate 701, and a limiting plate 703 is fixed between the other ends of the V-shaped spring pieces 702 on both sides, and the outer side surface of the limiting plate 703 is constructed with an extrusion surface 704 that fits the inclined surface of the limiting groove 201; through the support of the base plate 701, the V-shaped spring pieces 702 can be pressed to bend and deform when the limiting plate 703 is squeezed, and the position of the limiting plate 703 can be automatically changed, so that the limiting member 7 can smoothly enter the inner side of the splicing groove 2, and at the same time, it can automatically pop out when it is aligned with the position of the limiting groove 201. The design of the extrusion surface 704 can reduce the displacement resistance when contacting the notch of the splicing groove 2, which is convenient for extrusion deformation, and the fit with the inclined surface of the limiting groove 201 can enhance the fit of the connection and improve the stability of the limit.

[0024] In an embodiment of the present invention, the opposite sides of the splicing plug board 3 are provided with a plurality of installation grooves 301 for limiting the position of the base plate 701, the inner side of the installation groove 301 is provided with a plurality of positioning holes 302, and the side of the base plate 701 away from the V-shaped spring piece 702 is integrally formed with a plurality of positioning blocks 705 that are plugged into the positioning holes 302; the opening of the installation groove 301 facilitates limiting the installation position of the base plate 701, and the cooperation between the positioning holes 302 and the positioning blocks 705 can enhance the limiting strength of the installation position of the limiting member 7, which is not easy to fall off when assembling the wall panel body 1, thereby improving the convenience of the assembly operation of the wall panel body 1.

[0025] In an embodiment of the present invention, the support member 4 includes a support block 401, and the side of the support block 401 that is in contact with the positioning plug-in 6 is integrally formed with a first trapezoidal tenon 402, and the side opposite to the support block 401 that is in contact with the splicing groove 2 is integrally formed with a second trapezoidal tenon 403. The positioning plug-in 6 includes an insert block 601, and the side of the insert block 601 that is in contact with the support block 401 is provided with a second mortise 602 for plugging with the first tenon 402, and the side opposite to the insert block 601 is vertically provided with a plurality of positioning grooves 603; by combining the first tenon 402 on the support block 401 with the second mortise 602 on the insert block 601, the docking strength can be improved, the tightness of the splicing can be enhanced, and the fixity of the position of the positioning plug-in 6 can be ensured.

[0026] In an embodiment of the present invention, the two end facing surfaces of the splicing groove 2 located on one side of the splicing plug board 3 are provided with a first mortise 202 which is plugged into the second tenon 403, and the two end facing surfaces of the splicing grooves 2 on both sides are fixedly provided with a tough sealing rod 8, and the sealing rod 8 is abutted and connected with the positioning groove 603; when the support member 4 is inserted into the inner side of the splicing groove 2, the combination of the second tenon 403 and the first mortise 202 can further strengthen the splicing strength of the wall panel body 1, effectively enhancing the compressive strength of the connection, and the design of the sealing rod 8 can abut against the positioning groove 603 when installing the positioning plug-in 6, so that it can play a limiting effect when the positioning plug-in 6 is moved vertically, and at the same time, it can also strengthen the sealing of the connection between the positioning plug-in 6 and the wall panel body 1, and the sealing rod 8 is tough and can be squeezed to automatically shrink and deform when the positioning plug-in 6 is installed, making it easy to insert the positioning plug-in 6 into the splicing groove 2 of the two wall panel bodies 1.

[0027] In an embodiment of the present invention, the vertical length of the part of the positioning plug-in 6 protruding from the wall panel body 1 is the same as the vertical length of the support member 4, and the overall vertical length of the positioning plug-in 6 is the same as the length between the splicing plug-in 3 and the end of the wall panel body 1; the length of the positioning plug-in 6 moved to the outside of the wall panel body 1 is consistent with the vertical length of the support member 4, so that the support member 4 reaches a tight fit when combined with the positioning plug-in 6, and at the same time, the fit between the support member 4 and the splicing plug-in 3 can ensure the tightness of the connection between the two wall panel bodies 1.

[0028] In this embodiment of the present invention, several elastically deformable sealing strips 5 are fixedly mounted on the inner side of the splicing slot 2, located on one side of the retaining slot 201. Several sealing connection grooves 303 are formed on the side of the splicing plate 3, facing away from the wallboard body 1, to engage with the sealing strips 5. A frame 501 is fixedly mounted in the middle of the sealing strip 5, and the cross-section of the sealing strip 5 is T-shaped. The frame 501 in the middle of the sealing strip 5 enhances its structural strength, and the T-shaped cross-section enables it to better fill the gap when squeezed. When the splicing plate 3 is inserted into the splicing slot 2, the sealing strip 5 is squeezed into the sealing connection groove 303, tightly fitting the gap.

[0029] Working principle: This embodiment provides a prefabricated wall panel for green building design. When the prefabricated wall panels are spliced, the splicing plate 3 of one wall panel body 1 is inserted into the splicing groove 2 with the limiting groove 201 of another wall panel body 1. The size of the splicing plate 3 is adapted to the size of the splicing groove 2, which ensures the initial plug-in fit. As the splicing plate 3 goes deeper, the limiting piece 7 installed on the side of the splicing plate 3 gradually approaches the limiting groove 201. The extrusion surface 704 of the limiting piece 7 contacts the inclined surface of the limiting groove 201. Since the V-shaped spring piece 702 is elastic, during the insertion process, the V-shaped spring piece 702 is squeezed and deformed, so that the limiting plate 703 can smoothly pass through the opening of the limiting groove 201. When the limiting plate 703 reaches the appropriate position of the limiting groove 201, the V-shaped spring piece 702 resumes its deformation, and the limiting plate 703 is snapped into the limiting groove 201, realizing the initial fixation of the two wall panel bodies 1 in the horizontal direction, preventing lateral displacement between the wall panel bodies 1, and the positioning plug-ins 6 arranged at both ends of the splicing groove 2 can play a role in vertical positioning and support. When one side of the wall panel body 1 is placed, the positioning plug-in 6 can be moved out from the end position of the splicing groove 2 by knocking or the like, so that the protruding part of the positioning plug-in 6 can be inserted into the reserved positioning groove, and the vertical length of the protruding part of the positioning plug-in 6 is consistent with the vertical length of the support member 4. In this way, when splicing another wall panel body 1, the support member 4 on one side of the splicing plug-in board 3 can be inserted into the splicing groove 2, so that the first tenon 402 of the support member 4 is plugged into the second mortise 602 of the positioning plug-in 6, and the second tenon 403 is plugged into the first mortise 202 of the splicing groove 2 to form a mortise and tenon structure. Such a size design ensures that the positioning plug-in 6 can be accurately inserted into both ends of the splicing groove 2, and fits tightly with the support member 4, thereby enhancing the stability of the vertical limit of the wall panel body 1. The sealing rod 8 provided in the splicing groove 2 abuts against the retaining groove 603 on the side of the insert 601, further limiting the stability of the vertical movement of the insert 601. The sealing rod 8 also provides a certain sealing and buffering effect. The sealing strip 5 on the inner side of the splicing groove 2, located on the side of the limiting groove 201, cooperates with the sealing connection groove 303 of the splicing plug 3 to achieve a sealing function. The skeleton 501 in the middle of the sealing strip 5 enhances its structural strength, and its T-shaped cross-section enables it to better fill the gap when squeezed. When the splicing plug 3 is inserted into the splicing groove 2, the sealing strip 5 is squeezed into the sealing connection groove 303, tightly fitting the gap and preventing external water, air, etc. from entering the interior of the wall panel. This improves the sealing and thermal insulation performance of the wall panel and meets the design requirements of green buildings.
