[0001] This application relates to the technical field of ultra-low energy consumption building envelopes, and discloses a wall panel system for dry construction. Background Art

[0002] The construction field is one of the main areas of energy consumption and carbon emissions in China at present. Accelerating the promotion of energy conservation and carbon reduction in the construction field is of great significance for achieving carbon peak and carbon neutrality and promoting high-quality development. Optimizing the energy conservation and carbon reduction design of newly built buildings, improving the thermal insulation performance of building envelopes, and promoting the development of ultra-low energy consumption buildings are an important direction for energy conservation and carbon reduction in the construction field.

[0003] Currently, in the wall panel construction link of the building curtain wall construction field, the construction method of applying precast wall panels is relatively common. This construction method usually completes most of the processing and assembly tasks of the wall panel components in the factory, and then transports them to the building construction site for splicing and assembly, improving the operation efficiency and reducing the wet operation on site.

[0004] Based on the above precast wall panel construction operations, in order to achieve the design purpose of heat insulation, precast wall panels usually have heat insulation materials or are provided with heat insulation layers. However, the design solutions and ideas of only introducing heat insulation materials or heat insulation layers in precast wall panels can no longer meet the high requirements or urgent needs for energy conservation and carbon reduction in the current building curtain wall construction field. Summary of the Invention

[0005] In order to meet the high requirements or urgent needs for energy conservation and carbon reduction in the current building curtain wall construction field, this application provides a wall panel system for dry construction.

Both the main load-bearing keels and the heat insulation keels are fixed between the exterior wall plates and the interior wall plates. Keel heat insulation layers are filled between the main load-bearing keels and the exterior wall plates and the interior wall plates. The heat insulation keels are made of non-metallic materials and are arranged around the unit wall panels and at the splicing gap positions of adjacent unit wall panels.

[0007] By adopting the above technical solutions, the main thermal insulation layer is correspondingly filled between the exterior wall board and the interior wall board, playing the role of thermal insulation. On this basis, a multi-keel structure design of the main load-bearing keel and the heat insulation keel is introduced. On the basis of meeting the structural strength requirements of the unit wall board, the heat insulation and thermal insulation characteristics of the non-metallic material of the heat insulation keel located around the unit wall board and at the splicing gap position of adjacent unit wall boards are utilized to reduce the linear heat transfer coefficient of the whole wall board at the splicing joint position, thereby achieving the purpose of improving the thermal insulation performance of the unit wall board itself and the thermal insulation capacity at the splicing gap position of adjacent unit wall boards. At the same time, a keel thermal insulation layer is arranged for the main load-bearing keel usually made of metal material to improve the thermal insulation effect at the main load-bearing keel, so as to comprehensively improve the thermal insulation performance of the unit wall board itself, the thermal insulation effect at the splicing gap position of adjacent unit wall boards and the overall thermal insulation performance of the wall board system, and thus meet the high requirements or urgent needs for energy conservation and carbon reduction in the current field of building wall board construction.

[0009] By adopting the above technical solutions, a plate force transmission member is introduced at the splicing position of adjacent unit wall boards up and down or left and right. The plate force transmission member can not only be used in cooperation with the heat insulation keel to improve the structural strength of adjacent unit wall boards at the splicing position, so as to achieve the purpose of improving the overall structural strength of the spliced wall board system, but also provide an auxiliary positioning function for the splicing of adjacent unit wall boards to improve the convenience of the splicing and assembly operation.

[0010] Preferably, the unit wall board is provided with a first sealing strip and a second sealing strip. The first sealing strip is clamped in the middle of the heat insulation keel of adjacent unit wall boards. The second sealing strip penetrates through the unit wall board where it is located and extends out to the splicing gap position of adjacent unit wall boards, and the first sealing strip and the second sealing strip form a lapped sealing fit at the splicing gap of adjacent unit wall boards.

[0011] By adopting the above technical solutions, the first sealing strip and the second sealing strip that form a lapped sealing fit at the splicing gap position of adjacent unit wall boards are used to improve the sealing effect of the wall board system at the splicing position of adjacent unit wall boards to prevent water leakage, water seepage and air leakage, and at the same time, the thermal insulation effect at the splicing position of adjacent unit wall boards can also be further improved to a certain extent.

[0012] Preferably, an exterior wall seal is hermetically arranged in the middle of the exterior wall boards of adjacent unit wall boards, and a compressible and multi-cavity weather-resistant rubber strip is selected as the exterior wall seal.

[0013] By adopting the above technical solution, the heat insulation effect at the splicing position of the exterior wall panels of adjacent unit wall panels is improved. At the same time, by utilizing the characteristics of the weather-resistant rubber strip such as compressibility, multi-chamber structure, and good durability, the sealing effect, installation adaptability, heat insulation effect, and service reliability at the splicing position of the unit wall panels are further improved. As a functional component for further water blocking and heat insulation, the exterior wall seal is one of the key measures to achieve airtightness, watertightness, and heat insulation performance in dry construction.

[0014] Preferably, an interior wall sealing material is hermetically arranged in the middle of the interior wall panels of the adjacent unit wall panels.

At the same time, the design requirements of sealing, waterproofing, and indoor visual aesthetics are taken into account.

[0016] Preferably, an installation groove is formed in the heat insulation keel.

On this basis, further making the first sealing rubber strip and the second sealing rubber strip form a perpendicular overlapping seal is beneficial to further improving the sealing and heat insulation effects at the splicing gap position of the adjacent unit wall panels, extending the flow path of water vapor and the heat conduction path that may enter the interior of the splicing gap of the adjacent unit wall panels, and hindering or delaying the spread of water vapor and heat to the interior of the room.

[0018] Preferably, a barbed structure is arranged on the first sealing rubber strip. The barbed structure is inserted into the installation groove of the heat insulation keel and forms a sealing fit with the installation groove. A clamping groove is formed on the inner wall of the heat insulation keel at the installation groove, and the barbed structure and the clamping groove of the heat insulation keel form a clamping fit.

[0019] By adopting the above technical solution, the barbed structure of the first sealing rubber strip can not only further improve the sealing and heat insulation effects between the first sealing rubber strip and the heat insulation keel, but also improve the installation stability between the first sealing rubber strip and the heat insulation keel.

[0020] Preferably, the first sealing strip is arranged as a split structure. The first sealing strip includes a fitting insert and a strip wrapper used in cooperation. The insert and the strip wrapper are respectively clamped and fixed to the heat insulation keels of the adjacent spliced unit wall panels.

The chamber part is clamped and fixed to the heat insulation keel, and the sealing insertion part is inserted into the strip wrapper and forms a sealing fit with the strip wrapper.

[0021] By adopting the above technical solution, a split combined structure is formed by the cooperation of the insert and the strip wrapper. Using this combined structure as the first sealing strip and cooperating with the second sealing strip to form a front-back overlapping seal. Introducing the split combined structure facilitates the operation convenience during the splicing operation of the unit wall panels, and at the same time can still meet the sealing requirements.

[0022] Preferably, an adjusting gasket is clamped between the main load-bearing keel and the heat insulation keel. The adjusting gasket is used to adjust the straightness deviation of the main load-bearing keel.

[0023] By adopting the above technical solution, using the adjusting gasket to adjust the straightness deviation of the main load-bearing keel during installation is beneficial to improving the accuracy of the installation and adjustment operation of the keel components.

[0024] Preferably, the heat insulation keel is adhesively fixed to the exterior wall board and the interior wall board, and an adhesive section is formed at the adhesive position. And foam pad pieces are clamped between the heat insulation keel and the exterior wall board and the interior wall board respectively. The foam pad pieces are used to separate the adhesive section formed by adhesion and the adjusting gasket.

[0025] By adopting the above technical solution, the heat insulation keel is fixedly connected to the exterior wall board and the interior wall board by adhesion, which is convenient for installation. And the adhesive section formed by adhesion is separated by the foam pad pieces, avoiding the adhesive material from affecting the pre-assembly of the other structural components, and at the same time providing an adjustment basis for the adjusting gasket to a certain extent.

And for the main load-bearing keels usually made of metal materials, a keel thermal insulation layer is arranged to improve the thermal insulation effect at the main load-bearing keels, so as to comprehensively improve the thermal insulation performance of the unit wall panel itself, the thermal insulation effect at the splicing gaps between adjacent unit wall panels, and the overall thermal insulation performance of the wall panel system, thereby meeting the high requirements or urgent needs for energy conservation and carbon reduction in the current building curtain wall construction field; 2. The thermal insulation keels around the unit wall panel are made of non-metallic materials, and the heat transfer coefficient of the thermal insulation keels is extremely low, which can effectively meet the index requirements of the ultra-low energy consumption of the wall panel system.

Detailed description of the specific implementation

[0030] The following will be further described in detail with reference to the attached Figure 1-8 This application will be further described in detail.

[0031] Embodiment 1 of the present application discloses a wall panel system for dry construction.

[0032] Embodiment 1 Refer to Figure 1 as shown Figure 1 It is a schematic diagram of the splicing state of the wall panel system in the embodiment of the present application. The wall panel system for dry construction includes a unit wall panel 1. The unit wall panel 1 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 whole wall panel, and is fixed to the main structure of the building by the dry hanging construction method. The dry hanging system or dry hanging parts 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.

[0033] Combined with Figure 2 and Figure 3 as shown Figure 2Schematic diagram of the splicing structure of the upper and lower adjacent unit wall panels in Embodiment 1 of the present application Figure 3 Schematic diagram of the splicing structure of the left and right adjacent unit wall panels in Embodiment 1 of the present application. The unit wall panel 1 includes an outer wall board 11 and an inner wall board 12. A keel member 2 is connected between the outer wall board 11 and the inner wall board 12. At the same time, a main thermal insulation layer 13 is filled and formed between the outer wall board 11 and the inner wall board 12. The keel member 2 plays a role in improving the structural strength of the unit wall panel 1, and the main thermal insulation layer 13 plays a role in heat insulation and heat preservation. The specific material selection of the main thermal insulation layer 13 is not limited and can be determined according to design requirements and actual needs. In the embodiments of this application document, the keel member 2 includes a main load-bearing keel 21 and a heat insulation keel 22. Among them, the main load-bearing keel 21 is processed from metal materials, such as steel keels, etc., and the heat insulation keel 22 is processed from non-metal materials, such as polyurethane profiles, nylon profiles, fiberglass profiles, etc. Generally speaking, the unit wall panel 1 is a rectangular standard structure. The specific structure of the main load-bearing keel 21 can be determined according to design requirements and actual needs, while 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 and heat preservation performance of the unit wall panel 1.

[0034] Combined with Figure 2 and Figure 3 As shown, in the embodiments of the present application, the specific materials and shapes of the outer wall board 11 and the inner wall board 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. The main load-bearing keel 21 is fixedly connected between the outer wall board 11 and the inner wall board 12. The side wall of the main load-bearing keel 21 perpendicular to the outer wall board 11 can be fixedly connected to the outer wall board 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 board 12 can be fixedly connected to the inner wall board 12 by means of screws passing through. On this basis, a keel thermal insulation layer 3 is filled and formed between the side wall of the main load-bearing keel 21 close to the inner wall board 12 and the inner side wall of the inner wall board 12, and a keel thermal insulation layer 3 is also filled and formed between the side wall of the main load-bearing keel 21 close to the outer wall board 11 and the inner side wall of the outer wall board 11. The specific material selection of the keel thermal insulation layer 3 is not limited and can be determined according to design requirements and actual needs. Introducing the keel thermal insulation layer 3 can effectively improve the heat insulation and heat preservation effect at the main load-bearing keel 21 made of metal materials, and further improve the heat insulation and heat preservation effect of the unit wall panel 1.

[0035] It should be noted that after the keel insulation layer 3 is filled and formed, the screw can directly pass through the keel insulation layer 3 to connect and fix the inner wall board 12 and the main load-bearing keel 21.

[0036] Combined with Figure 4 and Figure 5As shown Figure 4 is Figure 2 an exploded view of two unit wall panels spliced vertically in Figure 5 is Figure 3 an exploded view of two unit wall panels spliced horizontally in . In the embodiment of the present application, both side walls of the heat insulation keel 22 are fixedly connected to the inner wall board 12 and the outer wall board 11 by bonding. The bonding material selected is a bonding sealant, so that the heat insulation keel 22 is hermetically connected to the inner wall board 12 and the outer wall board 11, and thus the openings around the sides of the unit wall panel 1 are hermetically sealed. When bonding and fixing the heat insulation keel 22, first, a foam gasket 41 needs to be stuffed between the heat insulation keel 22, the inner wall board 12, and the outer wall board 11, and then the bonding sealant is filled. When stuffing the foam gasket 41, the side surface of the foam gasket 41 facing the inside of the unit wall panel 1 is coplanar or nearly flush with the side surface of the heat insulation keel 22 facing the inside of the unit wall panel 1, so as to facilitate the clamping of an adjusting gasket 43 between the heat insulation keel 22 and the main load-bearing keel 21. The adjusting gasket 43 is used to adjust the straightness deviation of the main load-bearing keel 21. After the heat insulation keel 22 is bonded and fixed to the inner wall board 12 and the outer wall board 11, a bonding glue section 42 is formed. The foam gasket 41 can separate the adjusting gasket 43 and the bonding glue section 42. In the embodiment of the present application, a foam gasket strip is specifically selected as the foam gasket 41. While playing a separating role, it can also play a good heat insulation and heat preservation role.

[0037] Combined with Figure 4 and Figure 5 As shown, when the unit wall panels 1 are spliced and assembled, whether it is two adjacent unit wall panels 1 spliced vertically or two adjacent unit wall panels 1 spliced horizontally, a plate force transmission member 5 is introduced at the position of the splicing gap to increase the structural stability of the adjacent unit wall panels 1 during splicing and assembly, as well as the connection structure strength and stability after splicing and assembly. Specifically, notches 221 for inserting the plate force transmission member 5 are formed at the positions of the heat insulation keel 22 facing the outside of the unit wall panel 1. The plate force transmission member 5 is made of a metal material. The two ends of the plate force transmission member 5 are respectively inserted into the notches 221 of the heat insulation keel 22 of the adjacent unit wall panels 1, so as to realize the positioning plug-in fit between the heat insulation keel 22 and the plate force transmission member 5.

[0038] It should be noted that in the embodiment of the present application, the basic structures of the plate force transmission members 5 connected to the splicing gaps of the two groups of unit wall panels 1 spliced vertically and the plate force transmission members 5 connected to the splicing gaps of the two groups of unit wall panels 1 spliced horizontally are the same, and the connection and fixing methods are also the same, only the connection directions of the plate force transmission members 5 are different.

[0039] Combined with Figure 4 and Figure 5As shown in the figure, specifically, when connecting two sets of unit wall panels 1 assembled by upper and lower splicing, one end of the plate force transfer member 5 with a closed design is positioned and inserted into the notch 221 of the heat insulation keel 22 at the upper end of the unit wall panel 1 of the lower unit wall panel 1. At the same time, it fits against the inner wall of the heat insulation keel 22 at the notch 221, and is fixedly connected by screws passing through the plate force transfer member 5, the heat insulation keel 22, the adjusting gasket 43, and the main stress keel 21. The other end of the plate force transfer member 5 with an open design is positioned and inserted into the notch 221 of the heat insulation keel 22 at the lower end of the unit wall panel 1 of the upper unit wall panel 1.

[0040] When connecting two sets of unit wall panels 1 assembled by left and right splicing, one end of the plate force transfer member 5 with a closed design is positioned and inserted into the notch 221 of the heat insulation keel 22 at the right end of the unit wall panel 1 of the left unit wall panel 1. At the same time, it fits against the inner wall of the heat insulation keel 22 at the notch 221, and is fixedly connected by screws passing through the plate force transfer member 5, the heat insulation keel 22, the adjusting gasket 43, and the main stress keel 21. The other end of the plate force transfer member 5 with an open design is positioned and inserted into the notch 221 of the heat insulation keel 22 at the left end of the unit wall panel 1 of the right unit wall panel 1.

[0041] Although the heat insulation keel 22 located around the unit wall panel 1 improves the sealing, heat insulation and heat preservation effect of the unit wall panel 1 itself during splicing and assembly, considering the splicing gap formed when adjacent unit wall panels 1 are spliced and assembled, it is still necessary to further optimize the design for the sealing, heat insulation and heat preservation requirements at the splicing gap position of adjacent unit wall panels 1. In the embodiment of the present application, the sealing, heat insulation and heat preservation optimization design is carried out respectively at the splicing gap position of the inner wall board 12 of adjacent unit wall panels 1, the splicing gap position of the outer wall board 11, and the middle splicing gap position where the heat insulation keel 22 and the plate force transfer member 5 are located.

[0042] Combined Figure 2 and Figure 3 As shown, an outer wall seal 6 is clamped in the middle of the outer wall board 11 of adjacent unit wall panels 1. In the embodiment of the present application, a compressible, multi - cavity weather - resistant rubber strip is selected as the outer wall seal 6, and screws are passed through the cavity at the middle position of the outer wall seal 6 into the outer wall board 11, so as to realize the fixed connection between the outer wall seal 6 and the outer wall board 11, and further achieve the purpose of blocking external water vapor, heat, etc. from entering the unit wall panel 1 through the splicing gap. Correspondingly, an inner wall sealing material 7 is clamped in the middle of the inner wall board 12 of adjacent unit wall panels 1. In the embodiment of the present application, the gap between adjacent inner wall boards 12 is filled with sealant and caulking compound to form the inner wall sealing material 7, so as to achieve the purpose of blocking heat from entering the unit wall panel 1 through the splicing gap.

[0043] Furthermore, a first sealant strip 8 and a second sealant strip 9 are introduced for use in combination with the unit wall panel 1. The first sealant strip 8 is snap-fixed in the middle of the heat insulation keel 22 of adjacent unit wall panels 1, while the second sealant strip 9 is inserted and fixed in the unit wall panel 1 and passes through the heat insulation keel 22 and extends out of the unit wall panel 1 to the splicing gap. The first sealant strip 8 and the second sealant strip 9 form a sealed fit at the splicing gap of adjacent unit wall panels 1, and the sealing, heat insulation and heat preservation effects of the unit wall panel 1 are further improved by using the path blocking and path extension effects formed by the sealed fit.

[0044] Combined Figure 4 with Figure 5 shown, specifically, in the embodiment of the present application, mounting grooves 222 and through grooves 223 are formed by mirror image on both sides of the heat insulation keel 22 close to the inner wall board 12 and the outer wall board 11. Among them, the mounting groove 222 is used for snap-fixing the first sealant strip 8, and the through groove 223 is used for the second sealant strip 9 to pass through the heat insulation keel 22 to the splicing gap. Referring to Figure 4 shown, when adjacent unit wall panels 1 are arranged in an up-and-down splicing manner, the first sealant strip 8 and the second sealant strip 9 here form a vertical abutting sealed fit, and the second sealant strips 9 of the adjacent two unit wall panels 1 here respectively form a vertical abutting sealed fit with the first sealant strip 8; referring to Figure 5 shown, when adjacent unit wall panels 1 are arranged in a left-and-right splicing manner, the first sealant strip 8 and the second sealant strip 9 here form a lap sealed fit with front and rear adjacent contacts, and the second sealant strip 9 here extends through the unit wall panel 1 throughout its length.

[0045] Combined Figure 4 with Figure 6 shown, Figure 6This is a schematic structural diagram of the first sealing strip at the splicing gap position of the unit wall panels spliced up and down in Embodiment 1 of the present application. For the first sealing strip 8 arranged at the up and down splicing gap position, the first sealing strip 8 here includes two parts: a clamping and installation part 81 and a sealing and abutting part 82. The clamping and installation part 81 is integrally clamped and fixed in the installation grooves 222 of two adjacent heat insulation keels 22. The sealing and abutting part 82 extends from the clamping and installation part 81 towards the second sealing strip 9 penetrating to the splicing gap, and the sealing and abutting part 82 is used to form a vertical abutting and sealing fit 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 hermetically abutted against the sealing and abutting part 82 of the first sealing strip 8, and the sealing and abutting part 82 wraps the end of the second sealing strip 9. Moreover, the abutting position of the second sealing strip 9 and the sealing and abutting part 82 on the side close to the exterior wall panel 11 is directly opposite to the exterior wall seal 6. Then, a small amount of water vapor, heat, etc. that may enter the splicing gap is blocked by the vertical lapping and sealing fit of the second sealing strip 9 and the sealing and abutting part 82, and needs to bypass the groove gap between the second sealing strip 9 and the through groove 223 and overcome the subsequent obstruction of the clamping and installation part 81 of the first sealing strip 8, increasing the path and difficulty of the dissipation or conduction of water vapor, heat, etc., and greatly improving the sealing, heat insulation and heat preservation technical effects of the heat insulation keel 22 at the splicing gap.

[0046] A clamping notch 224 is recessed at the inner wall of the notch of the through groove 223 of the heat insulation keel 22. A clamping part 91 is formed on the second sealing strip 9 corresponding to the opening 224. Through the clamping fit between the clamping part 91 and the clamping notch 224, the clamping and installation fixation of the second sealing strip 9 and the through groove 223 of the heat insulation keel 22 is realized.

[0047] It should be noted that the installation grooves 222 and the through grooves 223 on both sides of the heat insulation keel 22 can also adopt a symmetric opening scheme. At this time, the sealing and abutting parts 82 of the two first sealing strips 8 face the splicing gap at the same time, or the sealing and abutting part 82 of one first sealing strip 8 faces the side of the building, and the sealing and abutting part 82 of the other first sealing strip 8 faces the outdoor side.

[0048] Combined with Figure 6As shown, in addition, a barb structure 83 is integrally formed on the snap-fit ​​installation portion 81 of the first sealing strip 8, and the sealing, heat insulation and heat preservation effects at the splicing gap are further improved by the sealing cooperation formed by the barb structure 83 of the snap-fit ​​installation portion 81 and the inner wall of the installation groove 222. The snap-fit ​​installation portion 81 of the first sealing strip 8 includes a middle section 811 for extending to form a sealing abutment portion 82 and end sections 812 formed at both ends of the middle section 811, and the circumferential sides of the end sections 812 at both ends are formed with the above-mentioned barb structure 83, and the barb structure 83 is inserted into the corresponding installation groove 222 of the heat insulating keel 22, thereby forming a sealing cooperation. The middle section 811 cooperates with the sealing abutment 82 to achieve the purpose of wrapping the end of the second sealing strip 9. Specifically, the sealing abutment 82 extends toward the splicing gap away from the end of the middle section 811 to form a protrusion structure 821, and the other side of the sealing abutment 82 away from the protrusion structure 821 is flat. The protrusion structure 821 cooperates with the sealing abutment 82 and the middle section 811 to wrap the end of the second sealing strip 9 to prevent water vapor, heat, etc. from escaping and conducting directly inward through here.

[0049] On this basis, combined with Figure 4 , Figure 5 as well as Figure 6 As shown, the heat insulating keel 22 is formed with a snap-fit ​​groove 225 at the inner wall position of the installation groove 222 near the groove opening. In addition to being able to form a sealing fit with the inner wall of the installation groove 222, the barb structure 83 located at the transition position between the middle section 811 and the end section 812 can also form a snap fit with the snap-fit ​​groove 225 of the heat insulating keel 22, thereby achieving the purpose of fixing the first sealing strip 8 at the joint gap between the two heat insulating keels 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, the density of the barb structure 83 on one end section 812 is relatively large, and the density of the barb structure 83 on the other end section 812 is relatively small. During specific use, the end section 812 on the side with higher density of the barb structure 83 is inserted into the insulating keel 22 where the installation groove 222 is located, and is used to lock and connect with the plate force transmission component 5, while the end section 812 on the side with lower density of the barb structure 83 is inserted into the insulating keel 22 where the installation groove 222 is located to form a positioning plug-in fit with the plate force transmission component 5.

[0050] Moreover, the end section 812 with a relatively low density of the barbs structure 83 has a thinner diameter, a larger volume of a single barbs structure 83, and a larger opening angle, so as to be applicable to the sealed fit state formed during positioning and insertion; correspondingly, the end section 812 with a relatively high density of the barbs structure 83 has a thicker diameter, a smaller volume of a single barbs structure 83, and a smaller opening angle, so as to be applicable to the sealed fit state formed during the preliminary fixation of the first sealing strip 8, and at the same time further improve the sealing effect at the position, so as to further block the water vapor and heat directly dissipated or conducted through the plane of the sealing abutting section 82 and the end sealing abutting position of the second sealing strip 9. During actual assembly, if the first sealing strip 8 is not inserted in place at one time, it needs to be loosened and inserted again. At this time, the frictional forces between the barbs structures 83 with different structural designs at both ends and the groove wall of the installation groove 222 are different, and it is easier to complete the secondary or multiple insertion actions.

[0051] It should be noted that in the embodiment of the present application, the specific design schemes of the barbs structures on the two end sections are different, but in other embodiments, a design scheme with exactly the same barbs structures on the two end sections can also be adopted.

[0052] It should be noted that when the adjacent unit wall panels 1 are in an up-and-down splicing state, the second sealing strip 9 is arranged vertically at this time and forms a vertical abutting and sealing fit with the first sealing strip 8; when the adjacent unit wall panels 1 are in a left-and-right splicing state, the second sealing strip 9 is arranged horizontally at this time and then forms a lap sealing fit with the first sealing strip 8 in a front-and-back adjacent contact.

[0053] Referring to Figure 5 As shown, specifically, for the first sealing strip 8 arranged at the left-and-right splicing gap position, the first sealing strip 8 here also has an intermediate section 811, an end section 812, and a barbs structure 83, but does not extend to one side of the second sealing strip 9 to form a sealing abutting portion 82 and a protrusion structure 821, but forms a lap sealing fit with the second sealing strip 9 arranged throughout in the splicing gap position in a front-and-back adjacent contact.

[0054] Embodiment 2 Combined with Figure 7 and Figure 8 shown, Figure 7 is a schematic diagram of the splicing structure of the left-and-right adjacent unit wall panels in Embodiment 2 of the present application, Figure 8 is an exploded view for showing the structure of the first sealing strip at the splicing gap position of the left-and-right spliced unit wall panels in Embodiment 2 of the present application. The difference between the dry construction wall panel system in Embodiment 2 of the present application and Embodiment 1 lies in: the specific structure of the first sealing strip 8 at the left-and-right splicing gap position is different.

[0055] In the embodiment of the present application, the first sealing strip 8 is also inserted into the installation groove 222 and is snap-fitted and fixed with the heat insulation keel 22, and the first sealing strip 8 and the second sealing strip 9 form a front-back overlapping sealing fit at the splicing gap of the adjacent unit wall panels 1. However, the first sealing strip 8 in the embodiment of the present application is a split combined structure. The first sealing strip 8 includes an insert 84 and a strip wrapping member 85 used in combination. Both the insert 84 and the strip wrapping member 85 are made of plastic or rubber materials. The insert 84 and the strip wrapping member 85 are respectively snap-fitted and fixed to the heat insulation keels 22 of the adjacent spliced unit wall panels 1. Specifically, in the embodiment of the present application, the insert 84 is snap-fitted and installed in the installation groove 222 of the heat insulation keel 22 on the right side of the left unit wall panel 1, and the strip wrapping member 85 is snap-fitted and installed in the installation groove 222 of the heat insulation keel 22 on the left side of the right unit wall panel 1.

[0056] 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 snap-fitted and fixed with the heat insulation keel 22 at the notch position of the installation groove 222. A plurality of hollow chambers are formed in the chamber portion 841, and the sealing insertion portion 842 extends from the end of the chamber portion 841 and is inserted into the strip wrapping member 85 to form a sealing fit with the strip wrapping member 85. The strip wrapping member 85 has a cavity, and a thorn structure 851 is formed on the inner wall of the cavity. The sealing insertion portion 842 is inserted into the cavity of the strip wrapping member 85 and forms a sealing fit with the thorn structure 851.

[0057] By adopting the split combined structure of the first sealing strip 8 in the embodiment of the present application, the insert 84 can be pre-installed on one side of the unit wall panel 1, and the strip wrapping member 85 can be pre-installed on the other side of the unit wall panel 1. When splicing and assembling the unit wall panels 1 on both sides, the sealing insertion portion 842 plays a guiding role during the process of being inserted into the strip wrapping member 85, thereby improving the convenience of the assembly operation.

[0058] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
