[0041] The embodiment of the present application discloses a dry construction wallboard system.

[0042] Embodiment 1

[0043] Referring to Figure 1 , as shown in the drawings, Figure 1This is a schematic diagram of the splicing state of the wall panel system in an embodiment of this application. A dry-installation wall panel system includes a unit wall panel 1, which is a curtain wall panel prefabricated and assembled in a factory. After being transported to the construction site, it is spliced ​​and assembled on-site to form a complete wall panel, and then fixed to the main structure of the building through a dry-hanging construction method. The dry-hanging system or dry-hanging components used in the dry-hanging construction are pre-fixed to the unit wall panel 1 and then fixed to the main structure of the building.

[0044] Combination Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the splicing structure of adjacent unit wall panels in Embodiment 1 of this application. Figure 3 This is a schematic diagram of the splicing structure of adjacent unit wall panels in Embodiment 1 of this application. Unit wall panel 1 includes an outer wall panel 11 and an inner wall panel 12. A keel component 2 connects the outer wall panel 11 and the inner wall panel 12, and a main thermal insulation layer 13 is filled and formed between the outer wall panel 11 and the inner wall panel 12. The keel component 2 enhances the structural strength of unit wall panel 1, and the main thermal insulation layer 13 provides thermal insulation. The specific material selection for the main thermal insulation layer 13 is not limited and can be determined according to design requirements and actual needs. In the embodiment of this application, the keel component 2 includes a main load-bearing keel 21 and a thermal insulation keel 22. The main load-bearing keel 21 is made of a metal material, such as a steel keel, while the thermal insulation keel 22 is made of a non-metallic material, such as polyurethane profiles, nylon profiles, or fiberglass profiles. Generally speaking, the unit wall panel 1 has a standard rectangular structure. The specific structure of the main load-bearing keel 21 can be determined according to the design requirements and actual needs. The heat insulation keel 22 needs to be located at the opening positions around the unit wall panel 1 to close the side openings of the unit wall panel 1 and improve the heat insulation performance of the unit wall panel 1.

[0045] Combination Figure 2 and Figure 3As shown, in the embodiments of the present application, the specific material and shape of the outer wall panel 11 and the inner wall panel 12 are not limited, and can be determined according to design requirements and actual needs. The main load-bearing keel 21 is a square hollow steel member, and is fixedly connected to the middle of the outer wall panel 11 and the inner wall panel 12. The side wall of the main load-bearing keel 21 perpendicular to the outer wall panel 11 can be fixedly connected to the outer wall panel 11 through an L-shaped plate 211 and a mechanical anchor bolt 212, and the side wall of the main load-bearing keel 21 close to the inner wall panel 12 can be fixedly connected to the inner wall panel 12 by means of screwing. On this basis, the side wall of the main load-bearing keel 21 close to the inner wall panel 12 is filled with a keel thermal insulation layer 3 in the middle of the inner side wall of the inner wall panel 12, and the side wall of the main load-bearing keel 21 close to the outer wall panel 11 is also filled with a keel thermal insulation layer 3 in the middle of the inner side wall of the outer wall panel 11. The specific material of the keel thermal insulation layer 3 is not limited, and can be determined according to design requirements and actual needs. The introduction of the keel thermal insulation layer 3 can effectively improve the heat insulation effect of the main load-bearing keel 21 made of metal material, and further improve the heat insulation effect of the unit wall panel 1.

[0046] It should be noted that after the keel thermal insulation layer 3 is filled, the screw can directly pass through the keel thermal insulation layer 3 to connect and fix the inner wall panel 12 and the main load-bearing keel 21.

[0047] In combination with Figure 4 and Figure 5 As shown, Figure 4 for Figure 2 the explosion schematic view of two unit wall panels spliced in up, down and left directions, Figure 5 for Figure 3The exploded view of two unit wallboards spliced left and right. In the embodiment of the present application, the two side walls of the thermal insulation keel 22 are fixedly connected with the inner wallboard 12 and the outer wallboard 11 by bonding. The bonding material used is bonding sealant, so that the thermal insulation keel 22 is sealingly connected with the inner wallboard 12 and the outer wallboard 11, and the openings around the side edges of the unit wallboard 1 are sealingly closed. When the thermal insulation keel 22 is bonded and fixed, the foam pad 41 needs to be filled in the middle of the thermal insulation keel 22 and the inner wallboard 12 and the outer wallboard 11, and then the bonding sealant is filled. When the foam pad 41 is filled, the side of the foam pad 41 facing the inside of the unit wallboard 1 is coplanar or nearly flush with the side of the thermal insulation keel 22 facing the inside of the unit wallboard 1, so that the adjusting pad 43 can be clamped between the thermal insulation keel 22 and the main load-bearing keel 21, and the adjusting pad 43 is used to adjust the straightness deviation of the main load-bearing keel 21. After the thermal insulation keel 22 is bonded and fixed with the inner wallboard 12 and the outer wallboard 11, the bonding glue section 42 is formed, and the foam pad 41 can separate the adjusting pad 43 and the bonding glue section 42. In the embodiment of the present application, the foam pad strip is specifically selected as the foam pad 41, which not only has a separating function, but also has a good heat insulation and heat preservation effect.

[0048] In combination with Figure 4 and Figure 5 It is shown that the unit wallboard 1 introduces the slab force transmission member 5 at the position of the splicing gap when splicing and assembling, whether it is two groups of unit wallboards 1 adjacent above and below or two groups of unit wallboards 1 adjacent left and right, so as to increase the structural stability of the adjacent unit wallboards 1 when splicing and assembling, and the connection structure strength and stability after splicing and assembling. Specifically, the position of the thermal insulation keel 22 facing the outside of the unit wallboard 1 is formed with a notch 221 for inserting the slab force transmission member 5, the slab force transmission member 5 is made of metal material, and the two ends of the slab force transmission member 5 are respectively inserted into the notches 221 of the thermal insulation keels 22 of the adjacent unit wallboards 1, so as to realize the positioning and inserting cooperation of the thermal insulation keel 22 and the slab force transmission member 5.

[0049] It should be noted that in the embodiment of the present application, the basic structure of the slab force transmission member 5 connected at the splicing gap of the two groups of unit wallboards 1 spliced above and below and the slab force transmission member 5 connected at the splicing gap of the two groups of unit wallboards 1 spliced left and right is the same, and the connection and fixing method is also the same, only the connection direction of the slab force transmission member 5 is different.

[0050] In combination with Figure 4 and Figure 5As shown, specifically, when connected to two sets of unit wall panels 1 in upper and lower splicing assembly, the one end of the slab force transmission member 5 in closed design is positioned and inserted into the gap 221 of the thermal insulation joist 22 at the upper end of the unit wall panel 1 of the lower unit wall panel 1, while being fitted with the inner wall of the thermal insulation joist 22 at the gap 221, and fixedly connected by screwing through the slab force transmission member 5, the thermal insulation joist 22, the adjusting gasket 43 and the main force joist 21, while the other end of the slab force transmission member 5 in open design is positioned and inserted into the gap 221 of the thermal insulation joist 22 at the lower end of the unit wall panel 1 of the upper unit wall panel 1.

[0051] When connected to two sets of unit wall panels 1 in left and right splicing assembly, the one end of the slab force transmission member 5 in closed design is positioned and inserted into the gap 221 of the thermal insulation joist 22 at the right end of the unit wall panel 1 of the left unit wall panel 1, while being fitted with the inner wall of the thermal insulation joist 22 at the gap 221, and fixedly connected by screwing through the slab force transmission member 5, the thermal insulation joist 22, the adjusting gasket 43 and the main force joist 21, while the other end of the slab force transmission member 5 in open design is positioned and inserted into the gap 221 of the thermal insulation joist 22 at the left end of the unit wall panel 1 of the right unit wall panel 1.

[0052] Although the thermal insulation joists 22 at the positions around the unit wall panel 1 improve the sealing and heat insulation effect of the unit wall panel 1 in splicing assembly, considering the splicing gap formed by the adjacent unit wall panels 1 in splicing assembly, further optimization design is needed for the sealing and heat insulation of the adjacent unit wall panels 1 at the splicing gap positions. In the embodiment of the present application, the sealing and heat insulation optimization design is carried out for the splicing gap positions of the inner wall panel 12, the outer wall panel 11, the intermediate splicing gap positions of the thermal insulation joist 22 and the slab force transmission member 5 of the adjacent unit wall panels 1 respectively.

[0053] In combination Figure 2 and Figure 3 As shown, the outer wall panel 11 of the adjacent unit wall panel 1 is intermediately sealed with the outer wall sealing member 6, which is selected as a compressible, multi-cavity weather-resistant adhesive tape in the embodiment of the present application, and the cavity at the intermediate position of the outer wall sealing member 6 is screwed into the outer wall panel 11, so as to realize the fixed connection of the outer wall sealing member 6 and the outer wall panel 11, and further achieve the purpose of blocking the external water vapor, heat and the like from entering the unit wall panel 1 through the splicing gap. Correspondingly, the inner wall panel 12 of the adjacent unit wall panel 1 is intermediately sealed with the inner wall sealing material 7, which is filled with sealant and caulking glue in the embodiment of the present application, so as to form the inner wall sealing material 7, and further achieve the purpose of blocking the heat from entering the unit wall panel 1 through the splicing gap.

[0054] Further, the first sealing strip 8 and the second sealing strip 9 are introduced into the unit wallboard 1, the first sealing strip 8 is clamped and fixed in the middle of the adjacent unit wallboard 1, and the second sealing strip 9 is fixed in the unit wallboard 1 and is arranged through the heat insulation keel 22 to the joint gap of the unit wallboard 1. The first sealing strip 8 and the second sealing strip 9 are sealingly matched at the joint gap of the adjacent unit wallboard 1, and the path blocking and path lengthening effect formed by the sealingly matched further improves the sealing, heat insulation and heat preservation effect of the unit wallboard 1.

[0055] As shown in Figure 4 and Figure 5 , specifically, in the embodiment of the present application, the heat insulation keel 22 is mirror-symmetrically provided with a mounting groove 222 and a through groove 223 near the inner wall plate 12 and the outer wall plate 11, wherein the mounting groove 222 is used for clamping and fixing the first sealing strip 8, and the through groove 223 is used for arranging the second sealing strip 9 through the heat insulation keel 22 to the joint gap. Referring to Figure 4 , when the adjacent unit wallboard 1 is arranged in an up-down joint manner, the first sealing strip 8 and the second sealing strip 9 are vertically abuttingly and sealingly matched, and the second sealing strip 9 of the adjacent two unit wallboards 1 is respectively vertically abuttingly and sealingly matched with the first sealing strip 8; referring to Figure 5 , when the adjacent unit wallboard 1 is arranged in a left-right joint manner, the first sealing strip 8 and the second sealing strip 9 are front-back close contact and overlappingly and sealingly matched, and the second sealing strip 9 is longitudinally arranged through the unit wallboard 1.

[0056] As shown in Figure 4 and Figure 6 , the first sealing strip 8 and the second sealing strip 9 are arranged through the heat insulation keel 22, and the first sealing strip 8 is clamped and fixed in the middle of the adjacent unit wallboard 1, and the second sealing strip 9 is fixed in the unit wallboard 1 and is arranged through the heat insulation keel 22 to the joint gap of the unit wallboard 1. Figure 6The structure diagram of the first sealing strip at the splicing gap position of the unit wallboard in the up-down splicing in the embodiment 1 of the present application. For the first sealing strip 8 arranged at the up-down splicing gap position, the first sealing strip 8 here includes two parts of a clamping mounting part 81 and a sealing abutting part 82, the clamping mounting part 81 is clamped and fixed in the mounting groove 222 of the two adjacent thermal insulation keels 22 as a whole, the sealing abutting part 82 is formed by extending from the clamping mounting part 81 towards the second sealing strip 9 penetrating to the splicing gap, and the sealing abutting part 82 is used to form a vertical abutting and sealing cooperation with the second sealing strip 9 penetrating out of the through groove 223. The end of the second sealing strip 9 extending out of the through groove 223 is sealingly abutted to the sealing abutting part 82 of the first sealing strip 8, the sealing abutting part 82 wraps the end of the second sealing strip 9, and the abutting position of the second sealing strip 9 and the sealing abutting part 82 close to the side of the outer wall plate 11 is opposite to the outer wall sealing element 6. Therefore, the water vapor, heat and the like that may enter into the splicing gap are hindered by the vertical lapping and sealing cooperation of the second sealing strip 9 and the sealing abutting part 82, need to bypass the gap between the second sealing strip 9 and the through groove 223 and overcome the hindrance of the clamping mounting part 81 of the subsequent first sealing strip 8, increase the path and difficulty of the water vapor, heat and the like escaping or conducting, and greatly improve the sealing, heat insulation and heat preservation technical effect of the thermal insulation keel 22 at the splicing gap.

[0057] The bayonet 224 is formed in the inner recess of the slot opening wall of the through groove 223 of the thermal insulation keel 22, and the clamping part 91 is formed on the second sealing strip 9 corresponding to the opening 224. Through the clamping cooperation of the clamping part 91 and the bayonet 224, the clamping and mounting fixation of the second sealing strip 9 and the through groove 223 of the thermal insulation keel 22 is realized.

[0058] It should be noted that the mounting groove 222 and the through groove 223 on both sides of the thermal insulation keel 22 can also be symmetrically arranged. At this time, the sealing abutting parts 82 of the two first sealing strips 8 are simultaneously towards the splicing gap, or the sealing abutting part 82 of one first sealing strip 8 is towards one side of the building, and the sealing abutting part 82 of the other first sealing strip 8 is towards the outdoor side.

[0059] In combination with Figure 6As shown, in addition, the snap-fit mounting portion 81 of the first sealing strip 8 is integrally formed with a barb structure 83, and the barb structure 83 of the snap-fit mounting portion 81 is sealingly fitted with the inner wall of the mounting groove 222, thereby further improving the sealing and heat insulation effect at the spliced gap. The snap-fit mounting portion 81 of the first sealing strip 8 includes an intermediate section 811 for extending to form a sealing abutment portion 82, and end sections 812 formed at both ends of the intermediate section 811, and the barb structure 83 is formed on the circumferential side of each end section 812, and the barb structure 83 is inserted into the mounting groove 222 of the corresponding thermal insulation joist 22, thereby forming a sealing fit. The intermediate section 811 cooperates with the sealing abutment portion 82 to wrap the end portion of the second sealing strip 9, and specifically, the sealing abutment portion 82 extends away from the end portion of the intermediate section 811 to form a protruding structure 821 towards the spliced gap, and the other side of the sealing abutment portion 82 away from the protruding structure 821 is planar, and the protruding structure 821 cooperates with the sealing abutment portion 82 and the intermediate section 811 to wrap the end portion of the second sealing strip 9 to block the direct escape and conduction of water vapor and heat from this position.

[0060] On this basis, in combination with Figure 4 , Figure 5 and Figure 6 As shown, the thermal insulation joist 22 is integrally formed with a snap-fit groove 225 at the inner wall position of the mounting groove 222 near the slot opening, and in addition to the sealing fit with the inner wall of the mounting groove 222, the barb structure 83 at the transition position between the intermediate section 811 and the end section 812 can also be snap-fitted with the snap-fit groove 225 of the thermal insulation joist 22, thereby achieving the purpose of fixing the first sealing strip 8 at the spliced gap of the two thermal insulation joists 22. It should be noted that in the embodiment of the present application, the density of the barb structure 83 on the end sections 812 on both sides is different, and the density of the barb structure 83 on one side of the end section 812 is greater, and the density of the barb structure 83 on the other side of the end section 812 is smaller. In specific use, the end section 812 with a greater density of barb structure 83 is inserted into the thermal insulation joist 22 where the mounting groove 222 is used to be locked and connected with the plate force transmitting member 5, and the end section 812 with a smaller density of barb structure 83 is inserted into the thermal insulation joist 22 where the mounting groove 222 is positioned and inserted with the plate force transmitting member 5.

[0061] Moreover, the end section 812 with a smaller density of barb structures 83 has a smaller diameter, a larger volume of each barb structure 83, and a larger opening angle, so as to be suitable for the sealing fit state formed when the first sealing strip 8 is positioned and inserted; correspondingly, the end section 812 with a larger density of barb structures 83 has a larger diameter, a smaller volume of each barb structure 83, and a smaller opening angle, so as to be suitable for the sealing fit state formed when the first sealing strip 8 is preliminarily fixed, and further improve the sealing effect at the position, so as to further block the water vapor and heat directly escaping or conducting from the position of the sealing abutment section 82 and the end sealing abutment position of the second sealing strip 9. In actual assembly, if the first sealing strip 8 is not inserted in place at one time, it needs to be loosened for secondary insertion, at which time the barb structures 83 with different structural designs at both ends have different frictional forces with the groove walls of the mounting groove 222, and it is easier to complete the secondary or multiple insertion actions.

[0062] It should be noted that, in the embodiments of the present application, the barb structures on the two end sections have different specific design schemes, but in other embodiments, the barb structures on the two end sections can also have the same design scheme.

[0063] It should be noted that, when the adjacent unit wall panels 1 are in the up-down splicing state, the second sealing strip 9 is arranged in a vertical extension, and forms a vertical abutment sealing fit with the first sealing strip 8; when the adjacent unit wall panels 1 are in the left-right splicing state, the second sealing strip 9 is arranged in a horizontal extension, and forms an overlapping sealing fit in front-back close contact with the first sealing strip 8.

[0064] Referring to Figure 5 , specifically, for the first sealing strip 8 arranged at the left-right splicing gap position, the first sealing strip 8 also has the middle section 811, the end section 812, and the barb structure 83, but no longer extends to one side of the second sealing strip 9 to form the sealing abutment part 82 and the protruding structure 821, but forms an overlapping sealing fit in front-back close contact with the second sealing strip 9 arranged throughout at the splicing gap position.

[0065] Embodiment 2

[0066] Referring to Figure 7 and Figure 8 , it can be seen that, Figure 7 is a schematic view of the splicing structure of the left-right adjacent unit wall panels in Embodiment 2 of the present application, Figure 8 is an exploded schematic view of the first sealing strip structure at the splicing gap position of the unit wall panel in the left-right splicing state in Embodiment 2 of the present application. The dry construction wall panel system in Embodiment 2 of the present application is different from Embodiment 1 in that the specific structure of the first sealing strip 8 at the left-right splicing gap position is different.

[0067] In this embodiment, the first sealing strip 8 is also inserted into the mounting groove 222 and snapped into the thermal insulation keel 22. The first sealing strip 8 and the second sealing strip 9 form a front-to-back overlapping seal at the joint of adjacent unit wall panels 1. However, in this embodiment, the first sealing strip 8 is a separate assembly structure, comprising an insert 84 and a strip wrapper 85 for combined use. Both the insert 84 and the strip wrapper 85 are made of plastic or rubber, and are snapped into the thermal insulation keel 22 of adjacent spliced ​​unit wall panels 1. Specifically, in this embodiment, the insert 84 is snapped into the mounting groove 222 of the thermal insulation keel 22 on the right side of the left unit wall panel 1, and the strip wrapper 85 is snapped into the mounting groove 222 of the thermal insulation keel 22 on the left side of the right unit wall panel 1.

[0068] The insert 84 includes an integrally formed chamber portion 841 and a sealing insertion portion 842. The outer wall of the chamber portion 841 is snapped and fixed to the heat insulation keel 22 at the groove position of the mounting groove 222. The chamber portion 841 has multiple hollow chambers. The sealing insertion portion 842 extends from the end of the chamber portion 841 and is inserted into the adhesive strip wrapping member 85 to form a sealing fit with the adhesive strip wrapping member 85. The adhesive strip wrapping member 85 has a cavity, and the inner wall of the cavity has a barbed structure 851. The sealing insertion portion 842 is inserted into the cavity of the adhesive strip wrapping member 85 and forms a sealing fit with the barbed structure 851.

[0069] By adopting the split-type assembly structure of the first sealing strip 8 in the embodiments of this application, the insert 84 can be pre-installed on one side of the unit wall panel 1, and the sealing strip wrapping 85 can be pre-installed on the other side of the unit wall panel 1. When splicing and assembling the two side unit wall panels 1, the sealing insertion part 842 plays a guiding role in the process of inserting into the sealing strip wrapping 85, thereby improving the convenience of the assembly operation.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
