Description

Technical Field

[0001] This utility model relates to the field of roofing panel technology, and in particular to a foamed roofing panel that is easy to splice and assemble. Background Technology

[0002] The existing invention patent with publication number CN116427631A discloses a novel composite roof panel, including a roof panel body. The roof panel body is composed of multiple splicing panels and connectors. Each splicing panel is the same size and shape. One end of each splicing panel is provided with a first connecting part, and the other end is provided with a second connecting part. Two adjacent splicing panels are spliced ​​together through the first connecting part and the second connecting plate, and then connected and fixed by connectors. Decorative panels are also provided at the ends of the splicing panels on both sides. After the decorative panels and splicing panels are spliced ​​together, they are connected by connectors to form a whole roof panel with straight ends that fits against the roof surface.

[0003] Because both hooks of the connector are oriented towards the center of the connector, squeezing the connector tightly will not disengage the hooks from the slots. Therefore, after a connector is pressed down and fastened to the first and second connecting parts that are spliced ​​together, if the technician finds that there is a deviation between the splicing of the two roof panels that needs to be adjusted, or that the connector needs to be replaced, or that a certain part or area of ​​the roof panel needs to be replaced, they can only use tools such as screwdrivers and pry bars to pry off the connector. This makes the disassembly and reinstallation of the connector more cumbersome and difficult, and there is also a possibility that the connector may be damaged. Utility Model Content

[0004] To address the aforementioned technical deficiencies in the existing technology, this utility model provides a foamed roofing panel. By arranging the transverse locking teeth at the lower ends of the two connecting legs of the connector towards the outer side of the connector, the transverse locking teeth can be disengaged from the hook-and-limit groove by squeezing the connector. This facilitates the disassembly and installation of the connector by technicians, reduces the difficulty of roofing panel assembly and construction, and reduces the probability of damage to the connector.

[0005] The technical solution of this utility model to solve the above problems is as follows: A foamed roofing panel is provided, comprising multiple roofing panel units of the same specifications. One end of each roofing panel unit has an upwardly protruding first splicing portion, and the opposite end has an upwardly protruding second splicing portion. Adjacent roofing panel units are connected to each other by splicing the first splicing portion and the second splicing portion. Both the first splicing portion and the second splicing portion have snap-fit ​​grooves on their sides facing the center of the roofing panel unit. A hook-and-limit groove is also provided at the bottom of the side wall of the snap-fit ​​groove on the side of the roofing panel unit located at its center. The panel also includes a connector with two connecting legs. The two connecting legs are respectively inserted into one snap-fit ​​groove of each of the two spliced ​​roofing panel units and respectively connected to a hook-and-limit groove for limiting and securing the two roofing panel units.

[0006] Furthermore, the connector includes a “∩”-shaped main board and two connecting feet. The two connecting feet are arranged opposite each other and are respectively located on both sides of the main board. The lower ends of the two connecting feet are provided with transverse locking teeth for laterally inserting into the hook-and-limit groove.

[0007] Furthermore, a limiting protrusion is provided on the outer side of the connecting motherboard. The limiting protrusion has a limiting end face that is flush with the edge of the slot of the snap-fit ​​groove. The maximum distance from the limiting protrusion to the connecting leg is less than or equal to the depth of the slot of the snap-fit ​​groove.

[0008] Furthermore, the minimum distance from the limiting end face of the limiting protrusion to the transverse locking tooth is greater than or equal to the minimum distance from the hook-and-limiting groove to the edge of the locking groove.

[0009] Furthermore, the width of the region of the snap-fit ​​groove located above the hook-fitting limiting groove is greater than or equal to the maximum lateral length of the lateral snap-fit ​​teeth.

[0010] Furthermore, the connector is an elastic connector.

[0011] Furthermore, the roof panel unit includes a PVC performance board layer, a PVC foam board layer, and a weather-resistant layer, with the PVC foam layer disposed above the PVC performance board layer and the weather-resistant layer disposed above the PVC foam layer.

[0012] Furthermore, the weather-resistant layer is made of ASA material.

[0013] Furthermore, the roof panel unit is also provided with structural reinforcing ribs in the middle.

[0014] Furthermore, the first splicing part has a first splicing end face on its side, and the second splicing part has a second splicing end face on its side. The first splicing end face and the second splicing end face have the same shape so as to fit together.

[0015] The beneficial effects of this utility model are: First, this utility model provides a foamed roofing panel with a connector featuring outwardly oriented horizontal locking teeth. This allows technicians to easily remove the connector when using it to fix two interlocking roofing panel units. The two connecting legs of the connector can be bent inward by hand, making it easier to remove the connector later. This facilitates the replacement of roofing panel units or adjustment of their installation posture, reducing the difficulty of disassembling the connector and making it easier for technicians to reuse it.

[0016] Secondly, the connector also uses the limiting end faces of its two side limiting protrusions to limit and protect the two connecting legs, preventing the connecting legs from hitting the bottom of the locking groove and causing collision damage to the connector or roof panel unit at the locking groove. In addition, the limiting protrusions also serve to shield the locking groove, preventing rainwater from seeping into the locking groove and causing damage and corrosion to the transverse locking teeth due to prolonged immersion in water.

[0017] Third, the top layer of the roof unit uses a weather-resistant layer made of ASA material, the middle layer uses a PVC foam layer, and the bottom layer uses a PVC performance layer to comprehensively improve the roof panel's weather resistance, thermal insulation performance, and structural strength, including its sun protection, corrosion resistance, and other properties.

[0021] Please see Figures 1 to 4 A specific embodiment of this utility model of a foamed roofing panel includes multiple roofing units 1 of the same specifications. One end of each roofing unit 1 is provided with an upwardly protruding first splicing portion 11, and the opposite end is provided with an upwardly protruding second splicing portion 12. Adjacent roofing units 1 are spliced ​​together by the first splicing portion 11 and the second splicing portion 12. Both the first splicing portion 11 and the second splicing portion 12 are provided with a snap-fit ​​groove 13 on the side facing the center of the roofing unit 1, and the bottom of the side wall of the snap-fit ​​groove 13 located at the center of the roofing unit 1 is provided with a hook-fitting limiting groove 14. The panel also includes a connector 2, which has two connecting legs 22 for inserting into and snapping into the snap-fit ​​grooves 13. The connector 2 further fixes the two roofing units 1 by inserting the two connecting legs 22 into one snap-fit ​​groove 13 of each of the two spliced ​​roofing units 1.

[0022] For details, please refer to Figure 1 ,by Figure 1 Taking the orientation shown as an example, in this embodiment, the right side of the roof panel unit 1 is integrally provided with a first splicing part 11 and the left side is integrally provided with a second splicing part 12. Both the first splicing part 11 and the second splicing part 12 are upwardly protruding block structures. The right side of the first splicing part 11 is also provided with a first splicing end face 16 in the shape of a stepped surface, and the left side of the second splicing part 12 is also provided with a second splicing end face 17 in the shape of a stepped surface. Furthermore, both the left side of the first splicing part 11 and the right side of the second splicing part 12 are vertically integrated with protruding structures. The protruding structure on the left side of the first splicing part 11 cooperates with the side wall of the first splicing part 11 to form a snap-fit ​​groove 13, and the protruding structure on the right side of the second splicing part 12 cooperates with the side wall of the second splicing part 12 to form another snap-fit ​​groove 13. At the same time, the protruding structure on the right side facing the lower edge of the side wall of the first splicing part 11 and the protruding structure on the left side facing the lower edge of the side wall of the second splicing part 12 are horizontally provided with hook-fitting limiting grooves 14.

[0023] In this embodiment, the roof panel unit 1 is a rectangular or square panel.

[0024] Additionally, please see Figure 2 ,by Figure 2 Taking the orientation shown as an example, in this embodiment, the connector 2 is generally shaped like a "∩". The connector 2 specifically includes a main board 21 that is also shaped like a "∩" but with relatively shorter sides and two connecting legs 22. The two connecting legs 22 are located on the left and right sides of the main board 21, respectively. The lower ends of the two connecting brackets are both integrally provided with horizontal locking teeth 23, and the two horizontal locking teeth 23 are arranged facing away from each other.

[0025] For this, please refer to Figure 3 and Figure 4 ,by Figure 4 Taking the indicated orientation as an example, in this embodiment, when the construction workers install multiple roof panel units 1 onto the roof, for the first roof panel unit 1 and the second roof panel unit 1 to be installed, the construction workers can first make the first splicing end face 16 of the first roof panel unit 1 and the second splicing end face 17 of the second roof panel unit 1 abut against each other on the roof, and with the help of the stepped shape of the two splicing end faces, make the lower surface of the first roof panel unit 1 and the lower surface of the second roof panel unit 1 flush, so that the first roof panel unit 1 and the second roof panel unit 1 are connected to each other through the first splicing part 11 and the second splicing part 12 respectively. Then, at the positions of the first splicing part 11 and the second splicing part 12 that are joined together, a connector 2 is installed downwards, so that the left connecting leg 22 of the connector 2 is inserted downwards into the left snap-fit ​​groove 13 of the first splicing part 11, and the right connecting leg 22 is inserted downwards into the right snap-fit ​​groove 13 of the second splicing part 12. The lower transverse locking teeth 23 of the left connecting leg 22 are then inserted to the left into its left hook-fitting limiting groove 14, and the lower transverse locking teeth 23 of the right connecting leg 22 are also inserted to the right into its right hook-fitting limiting groove 14, to further secure the connection between the two roof panel units 1 and cover the splicing gap between the two roof panel units 1. Then, screws are used to nail and fix the two assembled roof panel units 1 to the roof position.

[0026] Following the above method, construction workers can install the third, fourth, and finally the last roof panel unit 1 onto the roof in sequence to ensure its stable function of providing rain and wind protection.

[0027] Further, please refer to Figure 2 and Figure 4 ,by Figure 2Taking the direction shown as an example, in this embodiment, to prevent the lower end of the connecting leg 22 and the transverse retaining tooth 23 from being soaked in rainwater for a long time due to rainwater dripping into the retaining groove 13, which would reduce the strength of the lower end of the connecting leg 22 and the transverse retaining tooth 23 and accelerate the aging process, a limiting protrusion 24 is provided on each of the left and right sides of the connecting motherboard 21. The cross-section of the limiting protrusion 24 is triangular. The left limiting protrusion 24 is integrally set on the left side wall of the connecting motherboard 21, and the right limiting protrusion 24 is integrally set on the right side wall of the connecting motherboard 21. The lower end surfaces of the two limiting protrusions 24 are respectively set as horizontal limiting end surfaces 25, so that when the connector 2 of this embodiment is installed in place, the left limiting protrusion 24 can cover the outer edge of the left slot of the left retaining groove 13, and the right limiting protrusion 24 can cover the outer edge of the right slot of the right retaining groove 13, thereby restricting rainwater from dripping directly into the retaining groove 13.

[0028] Furthermore, the sloping surfaces of the two limiting protrusions 24 can further guide rainwater to flow down to the roof panel unit 1, so as to further prevent rainwater from leaking into the snap-fit ​​groove 13.

[0029] In addition, in this embodiment, in order to further avoid damage to the connecting leg 22 caused by it directly hitting the bottom wall of the snap-fit ​​groove 13 when it is inserted into the snap-fit ​​groove 13, the distance from the limiting protrusion 24 to the lowest end of the connecting leg 22 is 1-3mm smaller than the groove depth of the snap-fit ​​groove 13; at the same time, in order to ensure that the limiting teeth can extend laterally into the hook-fit limiting groove 14 and abut against each other with the hook-fit limiting groove 14 for limiting, the distance from the limiting end face 25 to the upper end face of the lateral teeth 23 is 1-2mm smaller than the distance from the upper end groove wall of the hook-fit limiting groove 14 to the upper end groove opening of the snap-fit ​​groove 13.

[0030] In addition, in order to manually squeeze the connector 2 to bend the two connecting legs 22 inward so that the transverse locking teeth 23 disengage from the hook limiting groove 14 and thus disassemble the connector 2, the connector 2 is an elastic connector made of TPU material with appropriate elasticity and appropriate hardness characteristics, and the groove width of the area of ​​the locking groove 13 above the hook limiting groove 14 is 1-2 mm larger than the maximum transverse length of the transverse locking teeth 23.

[0031] It should be noted that you should refer to [link / reference]. Figure 4 The bevel at the opening of the snap-fit ​​groove 13 is chamfered. The increase in the width of the opening of the snap-fit ​​groove 13 caused by the bevel is not included in the width of the opening of the snap-fit ​​groove 13.

[0032] Further, please refer to Figure 1 In this embodiment, the roof panel unit 1 is also provided with a structural reinforcing rib 15 in the middle to improve the structural strength of the roof panel unit 1.

[0033] Furthermore, in this embodiment, in order to ensure that the roof panel unit 1 has a long service life, good thermal insulation function, and does not change color over a long period of time when exposed to wind and rain, the roof panel unit 1 includes, from bottom to top, a PVC performance board layer, a PVC foam board layer, and a weather-resistant layer. The weather-resistant layer is made of ASA material and can be a coating applied to the surface of the PVC foam board layer or a thin board layer attached to the surface of the PVC foam board layer.

[0034] Anything not mentioned above applies to existing technologies.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
