Description

Technical Field

[0001] The embodiments of the present invention relate to the field of building technology, and in particular, to a wind-resistant node structure, a wall enclosure system and a construction method thereof. Background Art

[0002] With the continuous development of the construction industry, metal sandwich panels have gradually been applied in various buildings. Most metal sandwich panels use two layers of high-quality color-coated steel plates (or stainless steel, aluminum-magnesium-manganese) as the face panels. After roll forming, through high-strength adhesives, the core material is strongly bonded to the metal face panel to form a flat, beautiful, fireproof, heat-insulating and sound-insulating building board with excellent performance. It has high stiffness and high bearing capacity, can effectively reduce the cost of support systems such as wall beams, and with factory prefabrication and on-site assembly, it can be widely used in prefabricated buildings.

[0003] Currently, when the commonly used sandwich panels in engineering are in use, under the action of wind suction on the wall surface, the sandwich panels are in a two-way plate stress state, and there are also bends in the span and width directions. When the wind force is large, the stress at the tongue-and-groove of the sandwich panels increases, and stress concentration is likely to occur at the bonded part of the core material and the metal face panel at the tongue-and-groove. When the stress exceeds the bonding strength between the core material and the face panel, the tongue-and-groove is torn and damaged. Summary of the Invention

[0048] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the scope of protection of the embodiments of the present invention.

[0049] The inventor found in the practice of the embodiments of the present invention that in the prior art, when the sandwich panel wall enclosure system is in use, especially in high-wind pressure areas or high-wind pressure areas with relatively high buildings, it is prone to be damaged by wind uplift.

[0050] The reason is that the current domestic and foreign literature on the bearing capacity of sandwich panel envelope systems mainly includes "Metallic faced thermal insulation sandwich panels for building" GB / T 23932-2009, "Technical specification for metallic faced thermal insulation sandwich panels" CECS411-2015, and "Self-supporting double skin metal faced insulating panels—Factory made products—Specifications" BS EN 14509:2013. The research on the bearing capacity and mechanical properties of sandwich panels in the above literature is based on the tests of single panels under different types of loads, and none of them studies the sandwich panel envelope system as a whole. Therefore, there is a great deviation from the actual stress and failure mode of the sandwich panel envelope system. The sandwich panel systems designed according to these standards will have great potential safety hazards, which is also the reason for the wind-induced damage of the sandwich panel wall envelope system in recent years.

[0051] At present, the width of the commonly used sandwich panels in engineering is generally between 500 and 1000 mm. Male and female ribs are provided on both sides of the sandwich panel. During installation, the male rib is first fixed on the supporting purlin with self-tapping screws, and then the female rib of the latter sandwich panel is buckled and inserted into the male rib of the previous panel, thus forming a concealed-nail tongue-and-groove structure connection. The spacing of the supporting purlins for fixing the sandwich panels is generally about 3 m.

[0052] The above connection structure makes the ratio of the span to the width of the sandwich panel generally between 2 and 3. Under the action of wind suction on the wall surface, the sandwich panel is in a two-way slab stress state, and there are bending moments in both the span and width directions. The bending along the width direction of the panel gradually opens the tight tongue-and-groove connection between the male and female ribs of adjacent sandwich panels. As the tongue-and-groove opens, the contact area between the male and female ribs is small, the compressive stress on the contact surface increases, and stress concentration occurs at the bonding position between the core material and the metal panel at the female rib tongue-and-groove. When the stress exceeds the bonding strength between the core material and the panel, the female rib at the tongue-and-groove is torn, resulting in failure. This stress and failure mode have been verified in multiple wind uplift tests of sandwich panel systems.

[0053] In view of the above problems, the embodiments of the present invention provide a wind uplift resistant joint structure, a wall envelope system and a construction method, which can effectively avoid the wind uplift damage caused by tongue-and-groove relaxation and stress concentration of the wall panel, and greatly improve the wind uplift resistance performance of the wall panel.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following describes the technical solutions in the embodiments of the present invention clearly and completely with reference to the accompanying drawings and specific embodiments. Apparently, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0058] The embodiments of the present invention provide a wind uplift resistance joint structure, including: a vertical purlin 20, a first wall panel 30, and a second wall panel 40. It should be noted that the wind uplift resistance joint structure provided by the embodiments of the present invention can be applied to a wall enclosure system. The wall enclosure system includes a plurality of vertical purlins 20 and a plurality of wall panels (depending on the installation positions, the plurality includes a first wall panel 30 and a second wall panel 40, and the structures of the first wall panel 30 and the second wall panel 40 can be the same or different). The wind uplift resistance joint structure is a local connection structure in the wall enclosure system, and the wall enclosure system may include a plurality of wind uplift resistance joint structures. The wind uplift resistance joint structure solution is as follows:

[0059] See Figure 1 And Figure 3, the vertical purlin 20 is used to be arranged on the wall body 10 and extends along the vertical direction of the wall body 10. The wall body 10 is the wall body 10 maintained by the wall surface enclosure system, including but not limited to the outer wall of a building, etc. The vertical purlin 20 is installed on the wall body 10 to form the support framework of the first wall panel 30 and the second wall panel 40.

[0060] See Figure 2 , the first wall panel 30 and the second wall panel 40 are arranged in sequence along the vertical direction of the wall body 10. The first wall panel 30 and the second wall panel 40 include but are not limited to metal sandwich panels. The structures of the first wall panel 30 and the second wall panel 40 can be the same, or can be slightly different in structure according to different installation requirements. In the embodiment of the present invention, without additional explanation, the structures of the first wall panel 30 and the second wall panel 40 are the same, and are only distinguished as "first" and "second" according to different installation positions.

[0061] See Figure 4 and Figure 5 , one end of the first wall panel 30 facing the second wall panel 40 is provided with a first connection part 31, and one end of the second wall panel 40 facing the first wall panel 30 is provided with a second connection part 41 that is used in cooperation with the first connection part 31. The second connection part 41 is connected to the first connection part 31 to form a rabbet structure. At least one of the first connection part 31 and the second connection part 41 is connected to the vertical purlin 20 through at least one first fastener 50.

[0062] The first connection part 31 is a male rib structure in the rabbet structure, and the second connection part 41 is a female rib structure in the rabbet structure. Of course, the positions of the male and female ribs can also be interchanged. Grooves and protrusions for mutual insertion are provided on the male and female ribs, and the first wall panel 30 and the second wall panel 40 are mutually inserted through the male and female ribs to form a concealed-nail rabbet structure connection.

[0063] The first fastener 50 passes through the first connection part 31 and is connected to the vertical purlin 20, so as to fix the first wall panel 30 on the vertical purlin 20. The vertical purlin 20 spans the first wall panel 30 and the second wall panel 40 in its extending direction. When wind load is borne on the first wall panel 30 and the second wall panel 40, the bending deformation of the wall panel along the extending direction of the vertical purlin 20 can be eliminated through the vertical purlin 20, thereby avoiding the loosening of the rabbet between the sandwich panels at the connection of the vertical purlin 20. The first fastener 50 passes through the second connection part 41 and is connected to the vertical purlin 20, which also has the same wind uplift resistance effect.

[0064] See Figure 4 and Figure 6, to further prevent the wall panel from bending and deforming along the extension direction of the vertical purlin 20, causing the connection of the tongue-and-groove structure to open, the wind uplift resistance joint structure further includes a plurality of second fasteners 60. The plurality of second fasteners 60 are arranged at intervals along the extension direction of the vertical purlin 20, and connect the first wall panel 30 and the second wall panel 40 to the vertical purlin 20. By adding the second fasteners 60, the first wall panel 30 and the second wall panel 40 can be closely attached to the vertical purlin 20 under the action of wind suction, eliminating the bending deformation along the extension direction of the vertical purlin 20, thereby avoiding the loosening of the tongue-and-groove structure between the first wall panel 30 and the second wall panel 40 at the connection of the vertical purlin 20. By adding the second fasteners 60, the second fasteners 60 can further connect the first wall panel 30 and the second wall panel 40 to the vertical purlin 20, improving the firmness between the vertical purlin 20 and the first wall panel 30 and the second wall panel 40, specifically solving the problems of the loosening of the tongue-and-groove structure and stress concentration caused by the double bending under the action of wind suction, and the resulting wind uplift damage, thereby greatly improving the overall wind uplift resistance performance.

[0065] In the embodiment of the invention, the first fastener 50 includes but is not limited to a φ6.3 self-tapping screw. The first fastener 50 can connect to the vertical purlin 20 through the first connecting portion 31 from the side of the first wall panel 30 facing away from the vertical purlin 20. According to different connection requirements, there can be multiple first fasteners 50, and the multiple fasteners are arranged at intervals along the width direction of the vertical purlin 20 (i.e., the span direction of the wall panel). According to the different width dimensions of the vertical purlin 20, the spacing distance of the fasteners can be adjusted accordingly. The first fastener 50 can also be a countersunk head self-tapping screw, etc. The self-tapping screw includes but is not limited to a full-thread and a half-thread. The manufacturing materials of the screw and the self-tapping screw include but are not limited to iron materials and stainless steel materials. The screw includes but is not limited to an internal hexagonal screw, an external hexagonal screw, a cross screw, and a slotted screw, etc. Further, for the convenience of installation, through holes can be pre-set at the preset positions of the first connecting portion 31, and the first fastener 50 can pass through the through holes to connect to the vertical purlin 20.

[0066] The second fastener 60 includes but is not limited to a φ4.8x20 blind rivet. By using the second fastener 60 to fix the metal panel of the wall panel to the vertical purlin 20, the wall panel can be closely attached to the vertical purlin 20 under the action of wind suction, eliminating the bending deformation along the width direction of the wall panel.

[0067] Continue to refer to Figure 5, in some achievable embodiments of the present invention, one achievable way of the vertical purlin 20 is that the vertical purlin 20 includes a U-shaped main body 21, and flanges 22 are respectively provided on two side walls of the U-shaped main body 21, and the two flanges 22 extend in opposite directions. The vertical purlin 20 is connected to the wall body 10 through the two flanges 22. The closed end of the U-shaped main body 21 faces the first connecting portion 31 and is connected to at least one of the first connecting portion 31 and the second connecting portion 41 through a first fastener 50. The U-shaped main body 21 and the flange 22 form a "Ji" shaped structure. The vertical purlin 20 includes, but is not limited to, a cold-formed thin-walled "Ji" shaped vertical purlin 20 with a thickness of 1.5 mm to 2.5 mm and a material of S350 carbon structural steel. The first wall panel 30 and the second wall panel 40 are attached to the closed end of the "Ji" shaped structure.

[0068] One way to install the wall panel is to first fix the "Ji" shaped vertical purlin 20 on the wall body 10 to form a support framework for the wall panel. Then, at the starting elevation position of the wall body 10, install the starting bracket of the wall panel, and then insert the second connecting portion 41 (female rib) at the bottom end of the wall panel, such as the first wall panel 30, into the installed starting bracket, and attach the first wall panel 30 to the side of the "Ji" shaped vertical purlin 20 facing away from the wall body 10. At the intersection of the first wall panel 30 and the vertical purlin 20, use a φ6.3 self-tapping screw to pass through the first connecting portion 31 of the first wall panel 30 to fix the first wall panel 30 to the vertical purlin 20. Correspondingly, a φ6.3 self-tapping screw can also be used to pass through the second connecting portion 41 of the second wall panel 40 to fix the second wall panel 40 to the vertical purlin 20.

[0069] After the first wall panel 30 is installed, then insert the second connecting portion 41 (female rib) at the bottom end of another wall panel, such as the second wall panel 40, into the first connection (male rib) at the top end of the first wall panel 30 to form a tongue-and-groove structure. Then, fix the first connecting portion 31 at the top end of the second wall panel 40 to the vertical purlin 20 through the first fastener 50. By analogy, the above process can be repeated for multiple subsequent wall panels to initially complete the installation of the wall surface maintenance system.

[0070] To further prevent the wall panel from bending and deforming along the extension direction of the vertical purlin 20, causing the connection of the tongue-and-groove structure to open, after multiple wall panels are installed according to the above process, at the joint where the vertical purlin 20 is attached to the wall panel, set φ4.8x20 blind rivets at an interval of 150 mm along the extension direction of the vertical purlin 20 (i.e., the width direction of the wall panel) to fix the metal panel of the wall panel to the vertical purlin 20.

[0071] Further, to improve the installation stability of the vertical purlin 20, in the embodiments of the present invention, a horizontal purlin is provided on the wall body 10, and the horizontal purlin extends along the transverse direction of the wall body 10. The vertical purlin 20 is fixedly connected to the flange of the horizontal purlin through the folded edge 22. In some embodiments, in order to make the installation of the wall panel more stable, some horizontal purlins are laid on the wall body 10, and the wall panel is also connected to the horizontal purlin, so as to improve the wind resistance of the wall panel in the length direction. One feasible way is that before installing the wall panel, first set the horizontal purlin on the wall body 10, then vertically lay the "channel-shaped" vertical purlin 20 outside the horizontal purlin, and use self-tapping screws with a diameter of φ5.5 to fix the folded edge 22 of the vertical purlin 20 to the flange of the horizontal purlin to form the support framework of the sandwich panel.

[0072] See Figure 5 and Figure 7 , to avoid tearing between the first fastener 50 and the wall panel when the wind load is large, when the first fastener 50 is connected to the wall panel, a reinforcing gasket 51 is further included. The first fastener 50 sequentially passes through the reinforcing gasket 51 and the first connecting portion 31 and is connected to the vertical purlin 20. And / or, the first fastener 50 sequentially passes through the reinforcing gasket 51 and the second connecting portion 41 and is connected to the vertical purlin 20.

[0073] When the wind load borne on the wall panel is large, the reinforcing gasket 51 can be added. The reinforcing gasket 51 includes but is not limited to a steel sheet with a thickness of 2 mm, a width of 18 mm, and a length of 70 mm. A through hole 52 for cooperating with the first fastener 50 is provided on the reinforcing gasket 51. The through hole 52 can be a pre-drilled hole with a diameter of φ8. The reinforcing gasket 51 plays a role in stress diffusion, avoiding stress concentration at the contact between the head of the self-tapping screw and the metal panel of the wall panel under strong wind action, resulting in the tearing and pulling off of the metal panel.

[0074] See Figure 8 and Figure 9 , to further avoid the loosening of the tongue-and-groove structure, the wind-resistant joint structure further includes a third fastener 70. The third fastener 70 is located on the side of the first wall panel 30 facing the vertical purlin 20 and passes through the first connecting portion 31 and the second connecting portion 41 to connect the first connecting portion 31 and the second connecting portion 41. After connecting the wall panel to the vertical purlin 20, further along the span direction of the wall panel, that is, the length direction, at the joint of the tongue-and-groove structures of two adjacent wall panels, the third fastener 70 passes through the metal panels of two adjacent wall panels and stitches them together to form a lock seam, thereby enhancing the wind resistance of the tongue-and-groove joint. The third fastener 70 includes but is not limited to self-tapping screws and rivets with a diameter of φ5.5x25. For example, see Figure 9, the first connecting portion 31 and the second connecting portion 41 are inserted and connected to form a rabbet structure, for example, the first connecting portion 31 is located below the second connecting portion 41. At a position 13 mm below the rabbet joint, along the span direction of the wall panel, self-tapping screws with a diameter of φ5.5x25 and a spacing of 200 mm are used to pass through the metal panels of the first connecting portion 31 and the second connecting portion 41 and stitch them together to form a lock seam. Along the span direction, that is, the length direction of the wall panel, the first wall panel 30 and the second wall panel 40 are locked together by the third fastener 70 at the rabbet joint to form an integral body, preventing the rabbet structure from loosening, and jointly bearing force through deformation coordination to enhance the wind uplift resistance.

[0075] In the embodiment of the present invention, in combination with Figure 3 , see Figure 10 and Figure 11 , in addition to the above-mentioned method of strengthening the wind resistance of the rabbet joint by the third fastener 70, the wind resistance of the rabbet joint can also be strengthened by adding a reinforcing auxiliary purlin 80.

[0076] One achievable way is that the wind uplift resistance joint structure further includes a reinforcing auxiliary purlin 80, which extends along the transverse direction of the wall 10 and is respectively connected to the first wall panel 30 and the second wall panel 40, and covers the rabbet joint between the first wall panel 30 and the second wall panel 40. The rabbet joint between the first wall panel 30 and the second wall panel 40 is locked together by the reinforcing auxiliary purlin 80 to form an integral body, preventing the rabbet structure from loosening, and jointly bearing force through deformation coordination to enhance the wind uplift resistance. The adjacent two wall panels are combined into an organic whole through the shear force of the reinforcing auxiliary purlin 80, and jointly bearing force greatly improves the overall flexural stiffness and bearing capacity.

[0077] In the embodiment of the present invention, one achievable way of the reinforcing auxiliary purlin 80 is to see Figure 11 , the reinforcing auxiliary purlin 80 includes a purlin web 81 and purlin side plates 82 connected to opposite ends of the purlin web 81, and the purlin web 81 and the two purlin side plates 82 form a U-shaped structure. The reinforcing auxiliary purlin 80 is connected to the first wall panel 30 and the second wall panel 40 by spanning the rabbet joint through the purlin web 81. The specifications of the U-shaped reinforcing auxiliary purlin 80 include but are not limited to C80x20x2.0. The purlin web 81 fits against the inner surface of the wall panel and is fixed to the metal panel of the wall panel. The adjacent two wall panels can be combined into an organic whole through the shear force of the reinforcing auxiliary purlin 80, and jointly bearing force greatly improves the overall flexural stiffness and bearing capacity.

[0078] Further, one way to strengthen the connection between the auxiliary purlin 80 and the wall panel is that for the parts of the auxiliary purlin web 81 on both sides of the rabbet joint, on one side, the fourth fastener passes through the first connecting part 31 and the second connecting part 41 to connect the auxiliary purlin web 81, the first connecting part 31 and the second connecting part 41. On the other side, the auxiliary purlin web 81 is connected to the second connecting part 41 through the fifth fastener. For example, at 12 mm above and 13 mm below the rabbet joint, along the span direction of the wall panel, that is, the length direction of the strengthening auxiliary purlin 80, with a spacing of 150 mm, blind rivets of φ4.8x20 are used to fix the auxiliary purlin web 81 and the metal panel of the wall panel. The structures of the fourth fastener and the fifth fastener can be the same, including but not limited to self-tapping screws or blind rivets. Further, since the fourth fastener needs to pass through the first connecting part 31 and the second connecting part 41, the fourth fastener can be slightly longer than the fifth fastener.

[0079] It should be noted that the above methods for strengthening the wind resistance of the rabbet joint can be applied alone or in combination to the wind uplift resistance joint structure, and the embodiments of the present invention do not make specific limitations.

[0080] In the embodiments of the present invention, the wind uplift resistance joint structure can be applied to the wall enclosure system, solving the problems of rabbet relaxation and stress concentration caused by the double-sided bending of the wall enclosure system under wind suction, and the resulting wind uplift failure, thereby greatly improving the overall wind uplift resistance performance. With high wind uplift resistance performance, it can be applied to high wind pressure areas or high wind pressure areas with tall buildings, such as strong typhoon areas in the southeast coast.

[0081] Correspondingly, referring to Figures 1 to 3 , the embodiments of the present invention also provide a wall enclosure system, including: a plurality of vertical purlins 20 and a plurality of wall panels, and the plurality of vertical purlins 20 and the plurality of wall panels can be connected through the wind uplift resistance joint structure described above. The specific scheme is as follows:

[0082] Combined with Figures 4 to 6 Referring to Figures 1 to 3 In combination with

[0083] It further includes a plurality of second fasteners 60 which are arranged at intervals along the extending direction of the vertical purlin 20 and connect the wall panels to the vertical purlin 20. By adding a third fastener 70, the first wall panel 30 and the second wall panel 40 can be closely attached to the vertical purlin 20 under the action of wind suction force, eliminating the bending deformation along the extending direction of the vertical purlin 20, thereby avoiding the loosening of the rabbet structure between the first wall panel 30 and the second wall panel 40 at the connection of the vertical purlins 20.

[0084] In the embodiment of the present invention, the vertical purlin 20 and the wall panels in the wall enclosure system are connected through a wind uplift resistance joint structure. By adding a second fastener 60 to the wind uplift resistance joint structure, the second fastener 60 can further connect the first wall panel 30 and the second wall panel 40 to the vertical purlin 20, improving the firmness between the vertical purlin 20 and the first wall panel 30 and the second wall panel 40, and specifically solving the problems of the loosening of the rabbet structure and stress concentration caused by bidirectional bending under the action of wind suction force, as well as the wind uplift damage caused thereby, thus greatly improving the overall wind uplift resistance performance.

[0085] To further avoid the loosening of the rabbet structure, the wall enclosure system further includes a third fastener 70 which is located on the side of the wall panel facing the vertical purlin 20 and passes through the first connecting portion 31 and the second connecting portion 41 of two adjacent wall panels to connect the first connecting portion 31 and the second connecting portion 41 of the two adjacent wall panels. And / or

[0086] The wall enclosure system further includes a reinforcing auxiliary purlin 80 which is located on the side of the wall panel facing the vertical purlin 20 and extends along the transverse direction of the wall body 10; the reinforcing auxiliary purlin 80 is respectively connected to two adjacent wall panels and covers the rabbet joint between the two adjacent wall panels. A plurality of reinforcing auxiliary purlins 80 are separated by the vertical purlin 20 along the length direction of the wall panel. Through the combined action of the reinforcing auxiliary purlin 80 and the vertical purlin 20, a plurality of wall panels are locked to form an integral body, avoiding the loosening of the rabbet structure, and jointly bearing force through deformation coordination to enhance the wind uplift resistance. Through the shear force of the reinforcing auxiliary purlin 80, two adjacent wall panels are combined into an organic whole, and jointly bearing force greatly improves the overall flexural stiffness and bearing capacity.

[0087] It should be noted that the wind uplift resistance joint structure included in the wall enclosure system can refer to the content in the above embodiments and will not be elaborated here one by one.

[0088] Correspondingly, the embodiment of the present invention further provides a construction method for a wall enclosure system, combined with Figures 1 to 6 , the construction method includes:

[0089] Step S101: Arrange a plurality of vertical purlins 20 on the wall body 10, and all the plurality of vertical purlins 20 extend along the vertical direction of the wall body 10 and are distributed at intervals along the transverse direction of the wall body 10;

[0090] Among them, the wall 10 is the wall 10 maintained by the wall enclosure system, including but not limited to the exterior wall of a building, etc. The vertical purlins 20 are installed on the wall 10 to form a support framework for a plurality of wall panels.

[0091] Step S102: Arrange a plurality of wall panels on a plurality of vertical purlins 20. Each wall panel extends along the transverse direction of the wall 10 and spans across a plurality of vertical purlins 20. The plurality of wall panels are arranged in sequence along the vertical direction of the wall 10. Among them, the wall panel has a top end and a bottom end arranged in opposite directions. The top end is provided with a first connecting portion 31, and the bottom end is provided with a second connecting portion 41. The top end and the bottom end of two adjacent wall panels are arranged opposite to each other, and the second connecting portion 41 is connected to the first connecting portion 31 to form a rabbet structure. At least one of the first connecting portion 31 and the second connecting portion 41 is connected to the vertical purlin 20 through at least one first fastener 50.

[0092] Among them, according to different installation positions among the plurality of wall panels, the plurality of wall panels include a first wall panel 30 and a second wall panel 40. The structures of the first wall panel 30 and the second wall panel 40 may be the same or different. The first wall panel 30 and the second wall panel 40 include but are not limited to metal sandwich panels. The first connecting portion 31 is a male rib structure in the rabbet structure, and the second connecting portion 41 is a female rib structure in the rabbet structure. Of course, the positions of the male rib and the female rib can also be interchanged. The male rib and the female rib are provided with grooves and protrusions that can be inserted into each other. The first wall panel 30 and the second wall panel 40 are connected to each other through the male and female ribs to form a concealed-nail rabbet structure connection. The first fastener 50 passes through the first connecting portion 31 and is connected to the vertical purlin 20, thereby fixing the first wall panel 30 on the vertical purlin 20. The vertical purlin 20 spans across the first wall panel 30 and the second wall panel 40 in its extending direction. When wind load is applied to the first wall panel 30 and the second wall panel 40, the bending deformation of the wall panel along the extending direction of the vertical purlin 20 can be eliminated through the vertical purlin 20, thereby preventing the rabbet between the sandwich panels from loosening at the connection of the vertical purlins 20. The first fastener 50 passing through the second connecting portion 41 and being connected to the vertical purlin 20 also has the same effect of resisting wind uplift.

[0093] Step S103: Arrange a plurality of second fasteners 60 on each vertical purlin 20. The plurality of second fasteners 60 are arranged at intervals along the extending direction of the vertical purlin 20, and the wall panel is connected to the vertical purlin 20.

[0094] By adding a second fastener 60, the first wall panel 30 and the second wall panel 40 can be closely attached to the vertical purlin 20 under the action of wind suction force, eliminating the bending deformation along the extension direction of the vertical purlin 20, thereby avoiding the loosening of the rabbet structure between the first wall panel 30 and the second wall panel 40 at the connection of the vertical purlins 20. By adding a second fastener 60, the second fastener 60 can further connect the first wall panel 30 and the second wall panel 40 to the vertical purlin 20, improving the firmness of the vertical purlin 20 with the first wall panel 30 and the second wall panel 40, and specifically solving the problems of the rabbet structure relaxation and stress concentration caused by the double bending under the action of wind suction force, as well as the wind uplift damage caused thereby, thus greatly improving the overall wind uplift resistance performance.

[0095] For example, one realizable way of the vertical purlin 20 is that the vertical purlin 20 includes a U-shaped main body 21, and flanges 22 are respectively provided on two side walls of the U-shaped main body 21. The U-shaped main body 21 and the flanges 22 form a "Ji" shaped structure. The two flanges 22 extend in opposite directions. The vertical purlin 20 is connected to the wall body 10 through the two flanges 22. The closed end of the U-shaped main body 21 faces the first connection part 31 and is connected to at least one of the first connection part 31 and the second connection part 41 through a first fastener 50.

[0096] When installing the wall panel, first fix the "Ji" shaped vertical purlin 20 on the wall body 10 to form a support framework for the wall panel. Then, at the starting elevation position of the wall body 10, install the starting bracket of the wall panel, and then insert the second connection part 41 (female rib) at the bottom end of the wall panel, such as the first wall panel 30, into the installed starting bracket, and attach the first wall panel 30 to the side of the "Ji" shaped vertical purlin 20 facing away from the wall body 10. At the intersection of the first wall panel 30 and the vertical purlin 20, use a φ6.3 self-tapping screw (first fastener 50) to pass through the first connection part 31 of the first wall panel 30 to fix the first wall panel 30 to the vertical purlin 20. Correspondingly, a φ6.3 self-tapping screw can also be used to pass through the second connection part 41 of the second wall panel 40 to fix the second wall panel 40 to the vertical purlin 20.

[0097] After the first wall panel 30 is installed, then insert the second connection part 41 (female rib) at the bottom end of another wall panel, such as the second wall panel 40, into the first connection (male rib) at the top end of the first wall panel 30 to form a rabbet structure. Then fix the first connection part 31 at the top end of the second wall panel 40 to the vertical purlin 20 through the first fastener 50. And so on, the above process can be repeated for multiple subsequent wall panels to initially complete the installation of the wall surface maintenance system.

[0098] After multiple wall panels are installed according to the above process, at the joint where the vertical purlin 20 is attached to the wall panel, set φ4.8x20 blind rivets (second fastener 60) at intervals of 150 mm along the extension direction of the vertical purlin 20 (i.e., the width direction of the wall panel) to fix the metal panel of the wall panel to the vertical purlin 20.

[0099] To further prevent the tongue-and-groove structure from loosening, in the construction method provided by the embodiment of the present invention, referring to Figure 8 and Figure 9 , after step S103, it further includes

[0100] Step S104: A third fastener 70 is provided on the side of the wall panel facing the vertical purlin 20. The third fastener 70 passes through the first connection part 31 and the second connection part 41 of two adjacent wall panels, and connects the first connection part 31 and the second connection part 41 of the two adjacent wall panels.

[0101] After connecting the wall panels to the vertical purlin 20, further, in the span direction of the wall panel, that is, the length direction, at the joint of the tongue-and-groove structures of two adjacent wall panels, the third fastener 70 passes through the metal panels of two adjacent wall panels and stitches them together to form a lock seam, thereby enhancing the wind resistance of the tongue-and-groove joint. The third fastener 70 includes but is not limited to self-tapping screws and rivets of φ5.5x25. For example, referring to Figure 9 , the first connection part 31 and the second connection part 41 are inserted and connected to form a tongue-and-groove structure. For example, the first connection part 31 is located below the second connection part 41. At 13 mm below the tongue-and-groove joint, in the span direction of the wall panel, at an interval of 200 mm, self-tapping screws of φ5.5x25 pass through the metal panels of the first connection part 31 and the second connection part 41 and stitch them together to form a lock seam. The first wall panel 30 and the second wall panel 40 are locked together by the third fastener 70 along the span direction, that is, the length direction of the wall panel, at the tongue-and-groove joint, to form an integral whole, preventing the tongue-and-groove structure from loosening, and jointly bearing force through deformation coordination to enhance the wind uplift resistance.

[0102] In the embodiment of the present invention, after step 103, in addition to the method of enhancing the wind resistance of the tongue-and-groove joint through step S104, the wind resistance of the tongue-and-groove joint can also be enhanced through step S105.

[0103] Furthermore, referring to Figures 10 to 11 , after S103, it further includes:

[0104] Step S105: A reinforcing auxiliary purlin 80 is provided on the side of the wall panel facing the vertical purlin 20. The reinforcing auxiliary purlin 80 extends along the transverse direction of the wall 10; the reinforcing auxiliary purlin 80 is respectively connected to two adjacent wall panels and covers the tongue-and-groove joint between the two adjacent wall panels.

[0105] For the tongue-and-groove joint between the first wall panel 30 and the second wall panel 40, the adjacent wall panels are locked together by the reinforcing auxiliary purlin 80 to form an integral whole, preventing the tongue-and-groove structure from loosening, and jointly bearing force through deformation coordination to enhance the wind uplift resistance. The adjacent two wall panels are combined into an organic whole through the shear force of the reinforcing auxiliary purlin 80, and the overall flexural stiffness and bearing capacity are greatly improved by jointly bearing force.

[0106] It should be noted that the methods for enhancing the wind resistance of the tongue-and-groove joints in the above steps S104 and S105 can be applied alone or in combination to the wind uplift resistance joint structure and the wall enclosure system. The embodiments of the present invention do not make specific limitations in this regard.

[0107] Furthermore, it should be noted that the wall enclosure system fabricated by the above construction method can refer to the relevant content of the wall enclosure system in the foregoing embodiments, and will not be elaborated herein one by one.
