A green building energy-saving roof

Abstract

The present invention relates to the field of building roofs, and specifically to a green building energy-saving roof. It includes a roof frame, a plurality of unit panels and a photovoltaic mounting frame, wherein the unit panel includes a panel body and a first connecting portion and a second connecting portion respectively located at two ends of the panel body, wherein the first connecting portion is provided with a connecting hook head, and the second connecting portion is provided with a buckle hook plate. During installation, the present invention is more convenient and quick to install and buckle because the locking structure of the buckle hook plate and the one-sided shrinkage of the clamping groove of the connecting hook head are buckled, and the double-sided shrinkage is locked after buckling, which can effectively prevent the formation of gaps due to loose connections between adjacent unit panels, ensure the overall sealing of the device, and promote the overall stability of the device. At the same time, the first groove and the second groove are provided on the supporting hook head and the buckle hook plate, so that the clamping portion of the photovoltaic mounting frame is not easy to slide downward after being clamped by the installation rib, and is not easy to fall out upward, thereby reducing the possibility of the photovoltaic panel being lifted up in windy weather and further improving the reliability of the installation.

Description

Technical Field

[0001] The invention relates to the field of building roofs, and in particular to a green building energy-saving roof. Background Art

[0002] Roof panels are the main structural components commonly used in the field of steel structure buildings, and are mainly used in composite roof systems. In the relevant technology, there are various forms of composite roof panel structures. Generally, composite roof panels include outer panels, inner panels and thermal insulation core materials, but the lock edge structures at both ends and the structures of the middle crests are different. The structure of the connection between the two roof panels and the crests of the roof panels affect the overall firmness, waterproof performance and installation form of the subsequent roof system.

[0003] CN203113634U discloses a snap-fit ​​metal composite roof, wherein a connection device is provided between adjacent metal composite roof panels, and a vertical edge snap-fit ​​connection mode is adopted to connect two roof panels. Although a certain connection tightness and waterproof performance can be guaranteed, the fasteners and hooks of the above scheme are not reliably snap-fitted and locked, and the two ends of the metal panel are relatively thin. After long-term use, the two ends of the panel will be deformed and easily loosened. At the same time, when the photovoltaic panel is installed after the roof panel is installed, the lower part of the clamp is connected to the roof panel occlusion or the crest of the roof panel, and then the upper part of the clamp is connected to the guide rail, and a rectangular area is formed by laying out a horizontal guide rail and a vertical guide rail to accommodate and fix the photovoltaic panel. Due to the inclined setting of the roof panel, the clamp is not reliably fixed, so that the clamp is easy to move downward and is easy to come off from the roof panel in windy weather, causing the photovoltaic panel to be lifted.

[0004] The information disclosed in the background technology section of the present invention is only intended to deepen the understanding of the general background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art. Summary of the invention

[0005] According to the deficiencies of the prior art, the present invention proposes a green building energy-saving roof to solve the problems in the existing energy-saving roof that the roof panel is inconvenient to install and is easy to loosen after connection, resulting in poor sealing and unreliable connection.

[0006] A green building energy-saving roof of the present invention adopts the following technical solution: comprising:

The first mating plane contacts the second mating plane to move the push plate toward the direction close to the snapping groove, and the push plate squeezes the snapping groove and the locking structure to deform them, thereby forming shrinkage on both sides of the lower part of the snapping groove and the locking structure; after the snapping is completed, the first connecting part and the second connecting part of the two adjacent unit plates form a complete mounting rib, and the photovoltaic mounting frame is installed on the mounting rib.

[0014] Optionally, a notch is provided on one side of the top of the connecting hook head close to the first mating surface thereof, and a hidden nail is provided at the notch, and the hidden nail connects the first connecting portion and the roof frame.

[0015] Optionally, the connecting hook head includes a hook edge and an offset strip located above the hook edge, one side of the hook edge is a first mating surface, the offset strip can move along a first direction, one side of the initial offset strip protrudes from the first mating surface, and the other side of the offset strip is coplanar with the hook edge, so that the connecting hook head is smaller than the snap-on hook plate; when the two unit plates are snapped together, the offset strip moves in a direction away from the first mating surface under the push of the second mating surface, and then one side protruding from the first mating surface is coplanar with the first mating surface, and the other side is offset with the side of the hook edge to tighten the snap-on hook plate.

[0016] Optionally, the notch is arranged on the dislocation strip and penetrates the upper and lower surfaces of the dislocation strip and the surface close to the first matching plane.

[0017] Optionally, the photovoltaic mounting frame includes a clamping portion and a horizontal grid, the clamping portion includes a left clamping foot and a right clamping foot, the left clamping foot and the right clamping foot are respectively clamped on the left and right sides of the mounting rib, the left clamping foot and the right clamping foot are fixed by bolts, and the horizontal grid is fixed to the upper ends of the left clamping foot and the right clamping foot by bolts.

When clamped, the push plate pushes the metal layer corresponding to the clamping groove to deform, so that the clamping groove and the locking structure form shrinkage on both sides.

[0023] The beneficial effect of the present invention is that each unit panel in a green building energy-saving roof of the present invention includes a panel body and a first connecting part and a second connecting part located at both ends of the panel body, the first connecting part is provided with a connecting hook head, and the second connecting part is provided with a buckle hook plate. During installation, because of the locking structure of the buckle hook plate and the single-sided shrinkage of the snap-on groove of the connecting hook head, the installation and buckling are more convenient and quick. After buckling, the double-sided shrinkage is locked, which can effectively prevent the formation of gaps due to loose connections between adjacent unit panels, ensure the overall sealing of the device, and promote the overall stability of the device.

[0024] Furthermore, the connecting hook head is configured as a hook edge connected to the first connecting body and a movable offset strip, one side of the initial offset strip protrudes from the first mating surface, and the other side of the offset strip is coplanar with the hook edge, so that the connecting hook head is smaller than the snap-on hook plate, further facilitating the snap-on engagement of the first connecting part and the second connecting part. When the two unit plates are snapped together, the offset strip moves, thereby protruding one side of the first mating surface so that it is coplanar with the first mating surface, and the other side is offset with the side surface of the hook edge to tighten the snap-on hook plate, making it more difficult to loosen after snapping, thereby further improving the reliability of the connection.

[0025] Furthermore, by arranging the first groove and the second groove on the supporting hook head and the buckled hook plate of the second connecting part, the clamping part (left clamping foot and right clamping foot) of the photovoltaic mounting frame is not easy to slide downward after being clamped by the mounting rib, and is not easy to slip out upward, thereby reducing the possibility of the photovoltaic panel being lifted up in windy weather and further improving the reliability of the installation.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] like Figures 1 to 9As shown, a green building energy-saving roof provided by an embodiment of the present invention includes a roof frame 100, a plurality of unit panels 300 and a photovoltaic mounting frame 200; the roof frame 100 is arranged on the roof, and is inclined downward at a preset angle to the horizontal plane during installation; each unit panel 300 can be connected to the roof frame 100, and two adjacent unit panels 300 can overlap and cooperate with each other along a first direction to form a panel assembly, and a plurality of panel assemblies are arranged along a second direction to form a roof panel of a preset area, and the first direction and the second direction are perpendicular to each other; the photovoltaic mounting frame 200 is installed above the roof panel, and the photovoltaic mounting frame 200 is used to install photovoltaic panels to achieve energy saving on the roof.

[0045] Each unit board body 300 includes a board body 310 , a first connection portion 320 and a second connection portion 330 , and the first connection portion 320 and the second connection portion 330 are respectively located at two ends of the board body 310 .

[0046] The first connecting portion 320 includes a first connecting body 321 and a connecting hook head 322 arranged on the first connecting body 321, one side surface of the connecting hook head 322 has a first matching plane and the first matching plane is coplanar with the corresponding side surface of the connecting body, and the lower bottom surface of the connecting hook head 322 is provided with a snap-in groove 323. In the initial state, the lower end of the snap-in groove 323 is shrinked away from the side of the first matching plane.

[0047] The second connecting portion 330 includes a second connecting body 331, a supporting hook head 332 and a snap-on hook plate 333. The supporting hook head 332 is located above the second connecting body 331, and one side surface of the supporting hook head 332 is a second matching plane, and the second matching plane is coplanar with the corresponding side surface of the second connecting body 331. The snap-on hook plate 333 is connected to the top of the supporting hook head 332 and cantilevers outward. The shape of the snap-on hook plate 333 is adapted to the shape of the connecting hook head 322, and then bent at its end to form a locking structure 3331, and the locking structure 3331 is adapted to the snap-on groove 323.

[0048] The cam 325 is provided with a push plate 325 on the first connecting body 321. In the initial state, one end of the push plate 325 extends out of the side of the first connecting body 321 which is coplanar with the first mating plane, and the other end of the push plate 325 corresponds to the lower end of the locking groove 323; when the buckling connection is completed, the buckling hook plate 333 is buckled on the outer side of the connecting hook head 322, and the locking structure 3331 is inserted into the locking groove 323. The first mating plane contacts the second mating plane to make the push plate 325 move in the direction close to the locking groove 323, and the push plate 325 squeezes the locking groove 323 and the locking structure 3331 to deform them, thereby forming shrinkage on both sides of the lower part of the locking groove 323 and the locking structure 3331 to prevent the locking structure from escaping from the locking groove 323. After the buckling is completed, the first connecting portion 320 and the second connecting portion 330 of the two adjacent unit plates 300 form a complete installation rib, and the photovoltaic mounting frame 200 is installed on the installation rib.

[0049] It needs to be explained that the unit plate body 300 is a filling plate, that is, the plate body 310, the first connecting part 320, and the second connecting part 330 of the unit plate body 300 all include an inner filling and a metal layer wrapped on the outside of the inner filling. The inner filling of the plate body 310 generally adopts rock wool, which can play a role in thermal insulation. The inner filling of the first connecting part 320 and the second connecting part 330 generally adopts polyurethane to increase the reliability of the connection. The metal layers of the plate body 310, the first connecting part 320 and the second connecting part 330 are integrally formed. When clamped, the push plate 325 pushes the metal layer corresponding to the clamping groove 323 to deform, so that the clamping groove 323 and the locking structure 3331 form two-side shrinkages.

[0050] Furthermore, a notch 324 is provided on one side of the top of the connecting hook head 322 close to its first mating surface, and a hidden nail 326 is provided at the notch 324 . The hidden nail 326 connects the first connecting part 320 and the roof frame 100 , thereby realizing the connection between the unit panel body 300 and the roof frame 100 .

[0051] Specifically, the roof frame 100 includes a main beam 110, a secondary beam 120 and a receiving square steel 130. The main beam 110 is arranged at intervals along the first direction and extends along the second direction. The secondary beam 120 is arranged above the main beam 110. The secondary beam 120 extends along the first direction and is arranged at intervals along the second direction. The receiving square steel 130 is arranged above the secondary beam 120. The receiving square steel 130 is arranged at intervals along the first direction and extends along the second direction. The main beam 110, the secondary beam 120 and the receiving square steel 130 together form a steel frame. During installation, first, one of the unit panels 300 is placed at a preset position of the roof frame 100 as required, and a hidden screw is installed in the recess 324. The first connecting portion 320 of the unit panel 300 is connected to the receiving square steel 130 by the hidden screw, and then another unit panel is placed. The second connecting portion 330 of the other unit plate body 300 is close to the first connecting portion 320 of the above unit plate body 300, that is, the second mating surface of the other unit plate body 300 is close to the first mating surface of the above unit plate body 300, and the buckle hook plate 333 is buckled on the outside of the connecting hook head 322, and the locking structure 3331 is inserted into the clamping groove 323. As the first mating surface and the second mating surface are close to each other, the push plate 325 pushes the clamping groove 323 and the locking mechanism to deform, and the clamping groove 323 and the lower end of the locking mechanism form two side shrinkages to complete the locking; according to the above method, multiple unit plates 300 are installed and connected in sequence along the first direction to form a panel assembly, and multiple panel assemblies are installed in sequence along the second direction to form a complete roof and complete the installation. After the installation is completed, the first connecting portion 320 and the second connecting portion 330 of the two mutually buckled unit plates 300 form a complete installation rib, and can cover the hidden screws, and the rainwater on the roof can be drained along the bottom of the installation rib. With such arrangement, during installation, since the locking structure 3331 and the snap-fit ​​groove 323 are unilaterally contracted, installation and fastening are more convenient and quick, and the double-sided contraction and locking after fastening can effectively prevent the formation of gaps due to loose connections between adjacent unit plates 300, thereby ensuring the overall sealing of the device and promoting the overall stability of the device.

[0052] It is also necessary to explain that the top of the first connecting body 321 is tapered away from the first mating plane, and the top of the second connecting body 331 is tapered away from the second mating plane, thereby forming an avoidance space to facilitate the buckling of the first connecting part 320 and the second connecting part 330, and at the same time facilitate the installation of the photovoltaic mounting frame 200.

[0053] In a further embodiment, the connecting hook head 322 includes a hook edge 3221 and an offset strip 3222 located above the hook edge 3221, and one side of the hook edge 3221 is a first mating surface. The offset strip 3222 can move along the snapping direction (first direction), and one side of the initial offset strip 3222 protrudes from the first mating surface, and the other side of the offset strip 3222 is coplanar with the hook edge 3221, so that the connecting hook head 322 is smaller than the snapping hook plate 333, further facilitating the snapping of the first connecting part 320 and the second connecting part 330. When the two unit plates 300 are snapped together, the offset strip 3222 moves in a direction away from the first mating surface under the push of the second mating surface, and then one side protruding from the first mating surface is coplanar with the first mating surface, and the other side is offset with the side of the hook edge 3221 to tighten the snapping hook plate 333, making it more difficult to loosen after snapping, thereby further improving the reliability of the connection. It should be further explained that, in this embodiment, the notch 324 is disposed on the dislocation bar 3222 and penetrates the upper and lower surfaces of the dislocation bar 3222 and the surface close to the first matching plane to facilitate the movement of the dislocation bar 3222 .

[0054] In a further embodiment, the photovoltaic mounting frame 200 includes a clamping portion and a horizontal grid 210, wherein the clamping portion is clamped on the mounting rib, and the horizontal grid 210 is fixed to the clamping portion. The clamping portion includes a left clamping foot 230 and a right clamping foot 220, wherein the left clamping foot 230 and the right clamping foot 220 are clamped on the left and right sides of the mounting rib, respectively, and the left clamping foot 230 and the right clamping foot 220 are connected and fixed by bolts, and the horizontal grid 210 is fixed to the upper ends of the left clamping foot 230 and the right clamping foot 220 by bolts. Specifically in this embodiment, refer to Figure 2 and Figure 3 The horizontal grilles 210 extend along the first direction and are arranged in plurality along the second direction at intervals, and each horizontal grille 210 is fixed to a plurality of clamping portions.

[0055] In a further embodiment, a plurality of first grooves 3332 are arranged at intervals on the outer surface of the snap-fit ​​hook plate 333 along the length direction (second direction) of the unit plate body 300, and a plurality of second grooves 3321 are arranged at intervals on the outer surface of the support hook head 332 away from the second mating surface along the length direction (second direction) of the unit plate body 300, the first grooves 3332 and the second grooves 3321 correspond in position, and the two side surfaces of at least one of the first grooves 3332 and the second grooves 3321 are inclined upward relative to a reference plane, and the reference plane is a horizontal plane, the inner surface of the right clamping foot 220 is provided with a first protrusion 221 adapted to the first groove 3332, and the inner surface of the left clamping foot 230 is provided with a second protrusion 231 adapted to the second groove 3321, the first protrusion 221 is arranged in the first groove 3332, and the second protrusion 231 is arranged in the second groove 3321.

[0056] Reference Figure 1It can be understood that when the roof is installed, it is tilted downward at a preset angle with the horizontal plane. After the left clamping foot 230 and the right clamping foot are installed in the installation rib, they may slide downward under the action of vibration, making the installation unreliable and causing the photovoltaic panel to shift. At this time, through the cooperation of the first protrusion 221 and the first groove 3332 and the cooperation of the second protrusion 231 and the second groove 3321, the left clamping foot 230 and the right clamping foot 220 are inserted into the installation rib. At the same time, by setting the first groove 3332 and / or the second groove 3321 to be tilted upward relative to the reference plane, the left clamping foot 230 and the right clamping foot 220 can be prevented from sliding downward, thereby improving the reliability of the installation.

[0057] In one embodiment, the side surfaces of the first groove 3332 and the second groove 3321 are both inclined upward relative to the reference plane, and the angles of the side surfaces of the first groove 3332 and the second groove 3321 being inclined upward relative to the reference plane are different. After the left clamping foot 230 and the right clamping foot 220 are installed, the first groove 3332 and / or the second groove 3321 are set to be inclined upward to prevent the left clamping foot 230 and the right clamping foot 220 from sliding downward. However, if there is strong wind, and the first groove 3332 and the second groove 3321 are both inclined upward at the same angle, then the photovoltaic panel may be flipped upward under the action of wind, and the left clamping foot 230 and the right clamping foot 220 may be pulled out of the installation rib upward. In this embodiment, by setting the first groove 3332 and the second groove 3321 to different angles, the possibility of the left clamping foot 230 and the right clamping foot 220 being pulled out of the installation rib upward can be reduced, thereby improving the reliability of installation.

[0058] In another embodiment, the two side surfaces of one of the first groove 3332 and the second groove 3321 are inclined upward relative to the reference plane, and the two side surfaces of the other of the first groove 3332 and the second groove 3321 are inclined downward relative to the reference plane. This arrangement ensures that the left clamping foot 230 and the right clamping foot 220 will not slide downward. At the same time, because the first groove 3332 and the second groove 3321 are inclined in opposite directions relative to the reference plane, compared with the solution in which the first groove 3332 and the second groove 3321 are inclined upward at the same time but at different angles, the first groove 3332 and the second groove 3321 have a stronger restraining effect on each other, making it more difficult for the left clamping foot 230 and the right clamping foot 220 to be pulled out from the mounting rib, further improving the reliability of the mounting.

[0059] In this embodiment, further, one of the two adjacent first grooves 3332 is inclined upward relative to the reference plane, and the other is inclined downward relative to the reference plane. Similarly, one of the two adjacent second grooves 3321 is inclined upward relative to the reference plane, and the other is inclined downward relative to the reference plane. During the installation process, the same photovoltaic panel must span at least two horizontal grids 210. Then, different groups of right clamping feet 220 that clamp the two horizontal grids 210 in the second direction may be in first grooves 3332 with different inclined directions (left clamping feet 230 may be in second grooves 3321 with different inclined directions), so that the clamping of the two ends of the photovoltaic panel is mutually restrained, and the clamping is more stable and reliable. Fig. 9 , Fig. 9 The arrangement of the first groove 3332 and the second groove 3321 of this embodiment is given. In the figure, a indicates a reference plane, b indicates a side surface of the first groove 3332, the first groove 3332 here is below the reference plane, the second groove 3321 opposite to the first groove 3332 here is above the reference plane, and another first groove 3332 adjacent to the first groove 3332 here is above the reference plane. c indicates the second groove 3321, which is on the back side from the perspective of the figure and is therefore indicated by a dotted line. The second groove 3321 here is below the reference plane.

[0060] In other embodiments, the corresponding set of first grooves 3332 and second grooves 3321 may be inclined in the same direction, the adjacent two first grooves 3332 may be inclined in opposite directions, the adjacent two second grooves 3321 may be inclined in opposite directions, the inner surface of the left clamping foot 230 may be provided with two second protrusions at intervals, the inner surface of the right clamping foot 220 may be provided with two first protrusions at intervals, the two second protrusions may match the adjacent two second grooves 3321, and the two first protrusions may match the adjacent two first grooves 3332, that is, the left clamping foot 230 and the right clamping foot 220 may be installed across two sets of first grooves 3332 and second grooves 3321, so that the installation is more reliable. Naturally, there are other combinations based on the ideas described above, which will not be described here.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
