Description

Technical Field

[0001] The utility model relates to the technical field of building connectors, in particular to a roof connection back plate and a roof panel assembly. Background Art

[0002] In the metal building enclosure system, the on-site composite metal roof system has been widely used due to its advantages of high economy and fast construction. The metal roof system generally includes a plurality of overlapping metal roof panels, and the overlapping parts of adjacent roof panels form a ridge, and thermal insulation cotton is also provided under the roof panels. At present, the commonly used connection method for the transverse overlap of the ends of metal roof panels in buildings is direct nailing on site. Specifically, a long strip of connecting backboard is provided at the transverse end of the metal roof panel, and each connecting backboard spans the ridge between two metal roof panels; the user nails from top to bottom so that the two overlapping metal roof panels are fixed to the connecting backboard respectively, and then the adjacent metal roof panels are connected by the connecting backboard and nails to form a whole.

[0003] However, according to the current waterproof specifications for the first and second level waterproofing requirements of building roofs, a flexible waterproof membrane must be installed between the metal roof panel and the thermal insulation cotton. The conventional method of nailing from top to bottom makes it easy for the screws to penetrate the membrane, causing roof leakage.

[0004] In addition, since this type of roof panel is a single-layer metal corrugated board, the board cross-section is easily deformed, and the nailing overlap method has low control over the installation accuracy of the board. The effective width of the roof panel cannot be guaranteed during the installation process, resulting in a large error in the effective width of the roof panel after installation; and stress is concentrated at the nailing point, and the strength and rigidity are not enough to withstand harsh weather conditions. Utility Model Content

[0005] The utility model provides a roof connection back plate and a roof panel assembly, which can at least solve one of the above technical problems.

[0006] In order to solve the above technical problems, one or more embodiments of the utility model provide a roof connection back plate and roof panel assembly, including a flat plate portion, an overlap portion and a plurality of bolts arranged in sequence along a first direction, the length direction of the flat plate portion is the first direction and a through hole is provided at one end along the first direction, the flat plate portion has a first side surface perpendicular to its thickness direction; the overlap portion is fixed to the other end of the flat plate portion along the first direction, and the overlap portion has an overlap surface parallel to the first side surface. One of the bolts is fixed to the overlap portion, and the remaining bolts are fixed to the flat plate portion, the bolts are perpendicular to the first side surface and protrude from the first side surface, and a nut is arranged at each bolt.

[0007] The flat plate portion has a flat state. In the flat state, the first side surface is the upper surface of the flat plate portion, and the overlapping surface is the upper surface of the overlapping portion and is lower than the first side surface.

[0008] One or more embodiments of the utility model further provide a roof panel assembly, comprising a plurality of roof panels arranged in sequence along a set direction, wherein adjacent roof panels are overlapped and a ridge is formed at the overlapped portion, and further comprising the above-mentioned roof connection back plate; the roof panel has a second direction perpendicular to the set direction, and one end of the bottom surface of the roof panel along the second direction is provided with a roof connection back plate;

[0009] The first direction of the roof connection back plate coincides with the set direction, and the roof panel is provided with a plurality of reserved holes, which are used for passing the bolts of the flat plate portion; the roof connection back plates under adjacent roof panels are overlapped with each other, and the bolts of the overlapping portion of one of the roof connection back plates are inserted into the through holes of the other roof connection back plate.

[0010] The beneficial effects of one or more of the above technical solutions are:

[0011] The roof connection back plate in the present scheme is provided with a flat plate portion and an overlapping portion, and bolts are respectively provided on the flat plate portion and the overlapping portion. When the flat plate portion is in a flat state, the bolts are perpendicular to the upward upper surface of the flat plate portion and protrude above the upper surface of the flat plate portion; the bolts here can be used to pass through the reserved holes reserved on the roof panel, thereby facilitating the bolts to pass through the roof panel from bottom to top.

[0012] That is, compared with the prior art method of fixing the metal roof panels and connecting the back panels by firing nails from top to bottom using a nail gun, the back panels connected in this solution have their own upwardly convex bolts and the bolts need to pass through the roof panels upward when they are matched with the roof panels, which can avoid the problem of the nails moving downward and passing through and damaging the waterproof membrane.

[0013] In addition, in the flat state, the first side surface of the flat plate portion is the upper surface, and the overlap surface is the upper surface of the overlap portion and is lower than the first side surface. This arrangement makes it easy to use the overlap portion to overlap multiple roof connection back panels in sequence when multiple roof connection back panels are connected to each other, reducing the situation where the roof connection back panel is lifted when overlapping with the adjacent roof connection back panel. It is also easy to use the overlap portion bolts to be inserted into the through holes of the flat plate portion to fix adjacent roof connection back panels. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0021] See also Figure 1-Figure 2 One embodiment of the utility model provides a roof connection back plate 1 and a roof panel 5 assembly, including a flat plate portion 101, an overlap portion 102 and a plurality of bolts arranged in sequence along a first direction. The length direction of the flat plate portion 101 is the first direction and a through hole 104 is provided at one end along the first direction. The flat plate portion 101 has a first side surface perpendicular to its thickness direction; the overlap portion 102 is fixed to the other end of the flat plate portion 101 along the first direction, and the overlap portion 102 has an overlap surface parallel to the first side surface. One of the bolts is fixed to the overlap portion 102 (i.e., the second bolt 3 shown in the figure), and the remaining bolts (i.e., the plurality of first bolts 2 shown in the figure) are fixed to the flat plate portion 101, the bolts are perpendicular to the first side surface and protrude from the first side surface, and a nut is arranged at each bolt. The flat plate portion 101 has a flat state. In the flat state, the first side surface is the upper surface of the flat plate portion 101, and the overlap surface is the upper surface of the overlap portion 102 and is lower than the first side surface.

[0022] It should be noted that the reserved hole here is a hole through which the bolt passes, and whether the reserved hole itself has threads is not limited here. For example, the reserved hole can be a plain hole, or the reserved hole has internal threads but the reserved hole diameter is larger than the outer diameter of the bolt so as not to hinder the bolt from passing through.

[0023] For details, see Figure 2 The nut here includes a nut body 403 with an inner screw hole 402, a stop ring 401 at the upper end of the nut, and a brim 404 at the lower end of the nut. The outer diameter of the brim 404 is larger than the outer diameter of the nut body 403. In this embodiment, an anti-loosening thread is provided at the end face of the brim 404.

[0024] Specifically, in this embodiment, a reinforcing groove 103 is further provided on the overlapping surface of the overlapping portion 102, and the reinforcing groove 103 is provided around the bolt on the overlapping surface. Preferably, the depth of the reinforcing groove is 4 mm, and the reinforcing groove is used to increase the structural strength of the overlapping portion.

[0025] It can be known that the flat plate portion 101 further has a second side surface, and the second side surface is arranged opposite to the first side surface, and the first side surface and the second side surface are parallel.

[0026] In this embodiment, the through hole 104 is a long hole that penetrates the flat plate portion 101 in the thickness direction, and the long hole extends in the width direction of the flat plate portion 101. When the through hole 104 is a long hole, it can reduce the difficulty of plugging the through hole 104 in the adjacent roof connection back plate 1 and the bolts at the overlap portion 102, thereby reducing the difficulty of connecting the roof panel 5.

[0027] In this embodiment, a reinforcing rib 105 is provided on the first side surface of the flat plate portion 101, the reinforcing rib 105 is perpendicular to the first side surface, and the reinforcing rib 105 extends along the first direction. Specifically, the reinforcing rib 105 is also a long strip plate, and the reinforcing rib 105 cooperates with the flat plate portion 101 to form an L-shaped plate structure. In some other embodiments, the reinforcing rib 105 can also be other forms such as a grid plate or a hollow plate. Preferably, the height of the reinforcing rib is 25 mm, and the height difference between the overlap surface and the first side surface in a flat state is 3 mm, so that two adjacent roof connection back panels can overlap and buckle with each other.

[0028] In this embodiment, the bolts are riveted to the flat plate portion 101 or the overlapping portion 102, and the central axes of the plurality of bolts are in the same plane.

[0029] Specifically, a plurality of rivet bolts and one rivet bolt are fastened to the roof connection back plate and the overlapping portion on the right side in different directions by riveting.

[0030] See also Figure 3-Figure 4 One or more embodiments of the utility model further provide a roof panel 5 assembly, comprising a plurality of roof panels 5 arranged in sequence along a set direction, adjacent roof panels 5 overlapped and a ridge is formed at the overlapped portion, and also comprising the above-mentioned roof connection back plate 1; the roof panel 5 has a second direction perpendicular to the set direction, and a roof connection back plate 1 is provided at one end of the bottom surface of the roof panel 5 along the second direction. The first direction of the roof connection back plate 1 coincides with the set direction, and the roof panel 5 has a plurality of reserved holes, which are used to pass the bolts of the flat plate portion 101; the roof connection back plates 1 under the adjacent roof panels 5 overlap each other, and the bolts of the overlapped portion 102 of one roof connection back plate 1 are inserted into the through holes 104 of the other roof connection back plate 1.

[0031] In this embodiment, the first side surface of the roof connection back plate 1 is in contact with the bottom surface of the roof panel 5 .

[0032] In this embodiment, the roof panel 5 includes a main body 52, a first curling edge 51 and a second curling edge 53. The main body 52 is provided with a first curling edge 51 at one end along the first direction and a second curling edge 53 at the other end. The first curling edges 51 and the second curling edges 53 of adjacent roof panels 5 overlap to form a ridge.

[0033] In this embodiment, the bolts of the overlapping portion 102 and the through holes 104 of the flat plate portion 101 are located below the first curling edge 51 or the second curling edge 53 .

[0034] In this embodiment, the distance between the vertical center lines of two adjacent ridges is the effective width L of the roof panel 5, and the distance between the center line of the bolts of the overlapped portion 102 and the center line of the through hole 104 in the roof connection plate is equal to the effective width L. This arrangement can effectively control the effective width of the roof panel after installation, making the connection of the roof panel more secure, improving the anti-leakage ability and wind resistance at the ridge, meeting the functional requirements, installation requirements and design requirements of the project, while also taking into account the maintenance of the roof in the later stage.

[0035] In this embodiment, the reinforcing rib 105 is fitted with the end surface of the roof panel 5 along the second direction. This arrangement facilitates the use of the reinforcing rib 105 to position the roof connection back plate 1 and the roof panel 5 in the second direction, and facilitates the protection of the end surface of the roof panel 5.

[0036] Usage process: S1, pass the first bolt riveted on the roof connection back plate through the reserved hole at the end of the roof panel 5 at the ridge, so that the roof connection back plate is tightly fitted with the bottom of the roof panel 5;

[0037] S2, install a nut 4 on each first bolt. The installation of the nut needs to be divided into two steps: initial tightening and final tightening. Initial tightening: first install the two nuts 4 at both ends of the roof connection back plate, and then install the multiple nuts 4 in the middle; Final tightening: After the multiple nuts 4 are initially tightened, the nuts are finally tightened to ensure that the roof panel 5 and the upper surface of the roof connection back plate are tightly aligned.

[0038] S3, to install the subsequent adjacent roof connection back plate, first insert the second bolt on the overlap portion into the through hole of the previous roof connection back plate, then pass the first bolt riveted on the roof connection back plate through the reserved hole at the end of the roof panel 5 at the ridge, so that the roof connection back plate is tightly fitted with the bottom of the roof panel 5, and screw a nut 4 into the second bolt 3.

[0039] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.
