Description

Technical Field

[0001] This invention relates to the field of sandwich panel connection structure technology, and in particular to a metal sandwich panel connection structure based on a continuous pad. Background Technology

[0002] In traditional metal sandwich panel systems, the male and female tongue and groove joints typically only engage with each other through two mortise and tenon structures. Under strong wind loads, this joint is prone to slippage, leading to wall detachment. Furthermore, existing backing plates are limited to dispersing screw stress and cannot enhance the mechanical interlocking between the tongue and groove joints. Additionally, non-four-sided tongue and groove sandwich panels use a male screw fixing and female tenon and tenon locking installation method, which only achieves continuity in one direction (parallel tongue and groove), lacking an overall connection structure in the direction perpendicular to the tongue and groove joints.

[0003] Utility model patent CN220954096U discloses an out-of-plane self-stabilizing support structure for vertical wall purlins, comprising a support base, a first mounting part, and a second mounting part. The support base is triangular, and the first mounting part is formed on one side of the support base, intersecting with it. The second mounting part is formed on the other side of the support base, also intersecting with it. The first mounting part is triangular and is fixedly connected to the wall purlin by self-tapping screws. The second mounting part is quadrilateral and is fixedly connected to the wall composite panel by self-tapping screws. The overall structural strength of this patent needs further improvement by connecting different metal sandwich panels into a single unit.

[0004] Therefore, providing a connection structure with stable connection structure is an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art and provide a metal sandwich panel connection structure based on a continuous pad.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] According to one aspect of the present invention, a metal sandwich panel connection structure based on a continuous pad is provided, comprising a wall purlin, a continuous pad, an edge finishing unit, and a plurality of metal sandwich panels. Each metal sandwich panel includes a male tongue and a female tongue and groove joint. The male and female tongue and groove joints of the same metal sandwich panel are arranged opposite to each other. The male and female tongue and groove joints of adjacent metal sandwich panels are connected by the continuous pad. Each continuous pad, male tongue and groove joint, and female tongue and groove joint includes a tenon and a mortise. The tenon and mortise are interlocked. The edge finishing unit is connected to the wall purlin through the continuous pad.

[0008] As a preferred technical solution, the male tongue and groove joint includes a first mortise, a second tenon, a third mortise, a fourth tenon, a seventh mortise, and an eighth mortise, and the female tongue and groove joint includes a first tenon, a second mortise, a third tenon, a fourth mortise, and a seventh tenon. The first tenon and the first mortise are fitted together, the second mortise and the second tenon are fitted together, the third tenon and the third mortise are fitted together, the fourth mortise and the fourth tenon are fitted together, and the seventh tenon and the seventh mortise are fitted together. The continuous pad is installed in the eighth mortise and is fitted with the fourth tenon, the fifth tenon, and the sixth mortise respectively.

[0009] As a preferred technical solution, the through-length pad includes a locking plate, a sixth tenon and a fifth mortise, and the female tongue and groove also includes a fifth tenon and a sixth mortise. The fifth mortise and the fifth tenon are fitted together, the sixth tenon and the sixth mortise are fitted together, and the fourth tenon and the locking plate are fitted together.

[0010] As a preferred technical solution, the first tenon and the third tenon have the same height, the second tenon and the fourth tenon have the same height, the fifth tenon has a higher height than the third tenon, and the seventh tenon has a higher height than the fifth tenon.

[0011] As a preferred technical solution, the length of the seventh tenon is less than the depth of the seventh mortise, and the seventh tenon and the seventh mortise form a decorative seam. The overlap length of the seventh tenon and the seventh mortise is not less than a preset distance, and the bottom of the seventh tenon and the bottom of the seventh mortise form a pressure adjustment seam.

[0012] As a preferred technical solution, the seventh mortise includes a first drainage slope, and the outward inclination angle of the first drainage slope is 1:10.

[0013] As a preferred technical solution, the eighth mortise includes a second drainage slope, and the fifth mortise and the second drainage slope form an angle not less than a preset angle.

[0014] As a preferred technical solution, the continuous pad further includes a first overlapping plate and a second overlapping plate, which are respectively disposed on both sides of the locking plate.

[0015] As a preferred technical solution, the edge trimming unit includes screws, π-shaped edge trimming parts, heat insulation blocks, and C-shaped edge trimming parts. The π-shaped edge trimming parts are installed in the gap between adjacent metal sandwich panels. The screws pass through the π-shaped edge trimming parts, the continuous pad, the heat insulation block, and the wall vertical purlin in sequence. The C-shaped edge trimming parts are installed on the π-shaped edge trimming parts.

[0016] As a preferred technical solution, the edge-trimming unit further includes a plug, which is installed on a continuous pad and disposed on both sides of the edge-trimming unit.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The continuous pad, male tongue and groove and female tongue and groove of the present invention all include tenons and mortises. The specific bending structure of the continuous pad is matched with the male tongue and groove and the female tongue and groove to form additional tenon and mortise and tenon constraints, which significantly increases the effective force transmission contact area between the male tongue and groove and the female tongue and groove, thereby effectively improving the load-bearing capacity and anti-slip performance of the connection node.

[0019] 2. The continuous pad of the present invention adopts a continuous design, which breaks through the limitation of traditional fastener pads only serving as local force transmission components. The continuous pad can selectively connect and integrate multiple metal sandwich panels into a continuous force transmission structure according to engineering needs.

[0020] 3. The present invention employs multiple tenons and mortises arranged in an alternating pattern, which greatly increases the path length and bending angle of the connection, and greatly consumes the kinetic energy of rainwater carried into the tongue and groove by wind load, thereby improving the water tightness and air tightness of the sandwich panel system at the tongue and groove joint.

[0021] 4. This invention incorporates a pressure-adjusting seam to ensure that the internal air pressure at the connection point is always equal to the outdoor atmospheric pressure. Utilizing the principle of a rain shield, this greatly enhances the waterproof performance of the tongue and groove joint.

[0022] 5. The outward inclination angle of the first drainage slope of the present invention is 1:10 to avoid water accumulation in the decorative seam; the fifth mortise and the second drainage slope form an angle not less than a preset angle to facilitate drainage inside the tongue and groove joint.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figures 1-7 As shown, a metal sandwich panel connection structure based on a continuous pad plate includes a wall purlin 5, a continuous pad plate 4, an edge finishing unit, and multiple metal sandwich panels 1. Each metal sandwich panel 1 includes a male tongue and groove joint 3 and a female tongue and groove joint 2. The male tongue and groove joint 3 and the female tongue and groove joint 2 of the same metal sandwich panel 1 are arranged opposite each other. The male tongue and groove joint 3 and the female tongue and groove joint 2 of adjacent metal sandwich panels 1 are connected by the continuous pad plate 4. The continuous pad plate 4, the male tongue and groove joint 3, and the female tongue and groove joint 2 all include tenons and mortises. The tenons and mortises fit together. The edge finishing unit is connected to the wall purlin 5 through the continuous pad plate 4.

[0034] In this embodiment, the present invention includes multiple metal sandwich panels 1. One side of each metal sandwich panel 1 has a female tongue-and-groove joint 2, and the opposite side has a male tongue-and-groove joint 3. Each metal sandwich panel 1 includes a metal face panel 11, a metal back panel 12, and a core material between them. The metal back panel 12 of the metal sandwich panel 1 abuts against the wall purlin 5. The continuous pad 4 adopts a continuous design, which allows the continuous pad 4 to selectively connect and integrate multiple metal sandwich panels 1 (i.e., multiple metal sandwich panels 1 can be installed on the same continuous pad 4) into a continuous force-transmitting integral structure according to engineering needs.

[0035] The horizontal axis runs along the length of the continuous pad 4, and the vertical axis runs perpendicular to the length of the continuous pad 4. On the horizontal axis, multiple metal sandwich panels 4 are arranged at intervals, and adjacent metal sandwich panels 1 are connected to the continuous pad 4 and the wall purlin 5 as a whole through edge finishing units. On the vertical axis, the male tongue and groove 3 of any metal sandwich panel 1 and the female tongue and groove 2 of the adjacent metal sandwich panel 1 (i.e., the connection method is that a male tongue and groove 3 and a female tongue and groove 2 are interlocked) are connected as a whole through the continuous pad 4.

[0036] The male tongue and groove joint 3 includes a first mortise 31, a second tenon 32, a third mortise 33, a fourth tenon 34, a seventh mortise 35, and an eighth mortise 36. The female tongue and groove joint 2 includes a first tenon 21, a second mortise 22, a third tenon 23, a fourth mortise 24, and a seventh tenon 27. The first tenon 21 and the first mortise 31 are fitted together. The second mortise 22 and the second tenon 32 are fitted together. The third tenon 23 and the third mortise 33 are fitted together. The fourth mortise 24 and the fourth tenon 34 are fitted together. The seventh tenon 27 and the seventh mortise 35 are fitted together. The through-plate 4 is installed in the eighth mortise 36 and is fitted with the fourth tenon 34, the fifth tenon 25, and the sixth mortise 26 respectively.

[0037] The continuous pad 4 includes a locking plate 43, a sixth tenon 41 and a fifth mortise 42, and the female tongue and groove 2 also includes a fifth tenon 25 and a sixth mortise 26. The fifth mortise 42 and the fifth tenon 25 are fitted together, the sixth tenon 41 and the sixth mortise 26 are fitted together, and the fourth tenon 34 is fitted together with the locking plate 43.

[0038] The first tenon 21 and the third tenon 23 are at the same height, the second tenon 32 and the fourth tenon 34 are at the same height, the fifth tenon 25 is at a higher height than the third tenon 23, and the seventh tenon 27 is at a higher height than the fifth tenon 25.

[0039] The length of the seventh tenon 27 is less than the depth of the seventh mortise 35 and the seventh tenon 27 and the seventh mortise 35 form a decorative seam. The overlap length of the seventh tenon 27 and the seventh mortise 35 is not less than a preset distance. The bottom of the seventh tenon 27 and the bottom of the seventh mortise 35 form a pressure adjustment seam.

[0040] The seventh mortise 35 includes a first drainage slope 351, and the outward inclination angle of the first drainage slope 351 is 1:10.

[0041] The eighth mortise 36 includes a second drainage slope 361, and the fifth mortise 42 and the second drainage slope 361 form an angle not less than a preset angle.

[0042] The continuous pad 4 also includes a first overlapping plate 45 and a second overlapping plate 46, which are respectively disposed on both sides of the locking plate 43.

[0043] In this embodiment, the female tongue and groove joint 2 is provided with the following tenons in sequence: first tenon 21, second mortise 22, third tenon 23, fourth mortise 24, sixth mortise 26 and seventh tenon 27; the male tongue and groove joint 3 is provided with the following tenons in sequence: first mortise 31, second tenon 32, third mortise 33, fourth tenon 34, eighth mortise 36 and seventh mortise 35; wherein the fourth tenon 34 is bent (bent towards the middle of the metal sandwich panel 1) to form a U-shaped waterproof retaining structure at the male tongue and groove joint 3; this is used to improve the load-bearing capacity of the metal sandwich panel while improving the water tightness and air tightness inside the tongue and groove joint.

[0044] The continuous pad 4 includes a J-shaped cross-section locking plate 43, with screw holes 44 on its straight section, a fifth mortise 42 at the bend in its bent section, and a sixth tenon 41 at its end; a first overlapping plate 45 and a second overlapping plate 46 connected to the locking plate 43, both with screw holes 44; the second overlapping plate 46 arches into a platform shape along the normal direction of the straight section of the locking plate 43. Adjacent continuous pads 4 contact each other through the first overlapping plate 45 or the second overlapping plate 46, aligning the screw holes 44 on the first overlapping plate 45 or the second overlapping plate 46. Subsequently, the edge finishing unit is connected and fixed to the wall purlin 5 by screws passing through the screw holes 44 and the heat insulation block 52. Since the length of the continuous pad 4 is much greater than the length of a single metal sandwich panel 1, along the length of the continuous pad 4, the same continuous pad 4 will be connected to multiple metal sandwich panels 1. The metal sandwich panels 1 of the same continuous pad 4 do not contact each other and leave a certain gap. At this gap, an edge-trimming unit is needed to connect the continuous pad 4 and the wall vertical purlin 5.

[0045] The long pad 4 is installed in the eighth mortise 36. The tongue and groove fit is as follows: the first tenon 21-first mortise 31, the second tenon 32-second mortise 22, the third tenon 23-third mortise 33, the fourth tenon 34-fourth mortise 24, the sixth tenon 41-sixth mortise 26, and the seventh tenon 27-seventh mortise 35 fit together.

[0046] The length of the continuous pad 4 satisfies: n×L+(n+1)×a (n is the number of metal sandwich panels 1, n≥1, L is the length of metal sandwich panel 1 along the tongue and groove direction, and a is the width of the joint between the panels).

[0047] Adjacent metal sandwich panels 1 are mainly locked together by a tongue-and-groove interlocking mortise and tenon structure. The sixth tenon 41 added to the continuous pad 4 increases the effective contact area. Combined with the continuous design, at least two adjacent spans of metal sandwich panels 1 are connected into a whole. More sets of sandwich panels are connected together by the overlapping plates set at both ends. This greatly enhances the wind resistance of the metal sandwich panels, supports a larger purlin spacing in the purlin system wall, and improves the technical and economic efficiency of the project.

[0048] The metal panel 11 covers the seventh tenon 27, the sixth mortise 26, the fifth tenon 25, the fourth mortise 24 and the third tenon 23 on one side of the female tongue and groove joint 2, and covers the seventh mortise 35, the eighth mortise 36 and the fourth tenon 34 on one side of the male tongue and groove joint 3; the metal back plate 12 covers the first tenon 21 and the second mortise 22 on one side of the female tongue and groove joint 2, and covers the first mortise 31 and the second tenon 32 on one side of the male tongue and groove joint 3.

[0049] The first tenon 21 and the third tenon 23 are at the same height, the second tenon 32 and the fourth tenon 34 are at the same height, the fifth tenon 25 is higher than the third tenon 23, and the seventh tenon 27 is higher than the fifth tenon 25.

[0050] The length of the seventh tenon 27 is less than the depth of the seventh mortise 35. The overlap length between the seventh tenon 27 and the seventh mortise 35 is not less than 6 mm, and the overlap is not tightly connected. There is a pressure adjustment gap of not less than 1 mm between the bottom of the seventh tenon 27 and the bottom of the seventh mortise 35. There is a decorative gap of not more than 20 mm between the seventh tenon 27 and the seventh mortise 35.

[0051] The seventh mortise 35 is provided with a first drainage slope 351 that slopes outward at an angle of 1:10.

[0052] The continuous pad 4 is made of metal or basalt fiber profile with a strength ≥350MPa and a thickness ≥2mm. This provides sufficient strength to give the entire sandwich panel system greater wind resistance.

[0053] The fifth mortise 42 and the second drainage slope 361 form an angle of not less than 25 degrees.

[0054] The edge finishing unit includes screws, a π-shaped edge finishing piece 51, a heat insulation block 52, and a C-shaped edge finishing piece 53. The π-shaped edge finishing piece 51 is installed in the gap between adjacent metal sandwich panels 1. The screw passes through the π-shaped edge finishing piece 51, the continuous pad 4, the heat insulation block 52, and the wall vertical purlin 5 in sequence. The C-shaped edge finishing piece 53 is installed on the π-shaped edge finishing piece 51.

[0055] The edge-finishing unit also includes a plug 54, which is installed on the continuous pad 4 and is located on both sides of the edge-finishing unit.

[0056] In this embodiment, the π-shaped edge trim 51 is fixed to the wall purlin 5 by fasteners that pass through the continuous pad 4 and the heat insulation block 52 in sequence; the mounting surface of the π-shaped edge trim 51 is covered with a C-shaped edge trim 53. The C-shaped edge trim 53 is used to provide waterproofing for the nailing surface on the π-shaped edge trim 51, and to conceal the nail heads for a more aesthetically pleasing appearance; the heat insulation block 52 is used to prevent the cold bridge effect.

[0057] A plug 54 is provided in the cavity formed by the male tongue and groove 3 and the female tongue and groove 2 on both sides of the π-shaped edge trim 51. The plug 54 further prevents rainwater or water vapor from entering the sandwich panel through the cavity.

[0058] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
