Description

Technical Field

[0001] The utility model relates to the technical field of roof panel construction, in particular to a steel structure roof panel pressure strip. Background Art

[0002] Steel structure roof panels are mainly made of color steel plates. In the process of building steel structure roofs, multiple color steel plates are often laid one by one, and the adjacent color steel plates are stacked at the joints. Since the color steel plates are very thin, in order to ensure the stability of the steel structure roof, it is necessary to use pressure strips at the joints of the color steel plates to press and fix them. The current pressure strips are mostly single plate structures. Although they can press and fix the joints of the color steel plates, there are still the following shortcomings:

[0003] (1) The existing battens have poor strength. When used outdoors for a long time, they are easily loosened by wind, which causes the color steel plate to warp or even fall off, affecting the normal use of the steel structure roof.

[0004] (2) The existing battens not only block the flow of rainwater, causing a large amount of water to accumulate on the steel structure roof, increasing the load-bearing capacity of the steel structure roof, but also due to its poor sealing performance, rainwater can easily penetrate into the batten installation holes and the gaps in the color steel plate, thus causing corrosion of the steel structure roof, posing certain safety hazards;

[0005] Therefore, there is an urgent need for a steel structure roof panel strip that can both ensure the structural stability of the steel structure roof and achieve sealing and drainage. Utility Model Content

[0006] In order to overcome the shortcomings of the background technology, the utility model discloses a steel structure roof panel batten, which can not only stably and effectively fix the overlap of the steel structure roof panels, greatly improving the wind resistance of the steel structure roof, but also effectively drain and discharge the accumulated water at the connection of the steel structure roof panels, effectively enhancing the waterproof performance of the steel structure roof.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A steel structure roof panel bead, comprising an upper bead, a lower bead, and a sealing strip installed between the upper bead and the lower bead, wherein the upper bead, the lower bead and the sealing strip are all long strip-shaped plate structures, both ends of the upper bead and the lower bead are provided with bends adapted to the steel structure roof panel, the lower surface of the upper bead is provided with a plurality of guide grooves which are arranged at intervals along the axial direction of the upper bead and are used for the circulation of rainwater, the upper surface of the upper bead is provided with a plurality of bosses which are arranged at intervals along the axial direction of the upper bead and are in a cone structure, the upper ends of the bosses are provided with upper screw holes which penetrate the upper bead, the upper surface of the sealing strip is provided with a plurality of lower screw holes which correspond one to one with the upper screw holes which penetrate the lower bead and are provided with the upper surface of the lower bead.

[0009] Furthermore, a plurality of inner notches which are arranged axially along the upper layering strip and are wide outside and narrow inside are arranged in an orderly manner on one side of the upper layering strip, and one end of the plurality of guide grooves respectively corresponds to the inner narrow ends of the adjacent inner notches.

[0010] Furthermore, the upper surface of the upper pressure strip is an inclined surface with one side on the same side as the inner notch being higher than the other side.

[0011] Furthermore, the plurality of guide grooves on the lower surface of the upper layer bar form a plurality of protrusions with isosceles triangle structures in cross section on the upper surface of the upper layer bar.

[0012] Furthermore, the upper pressure strip, the sealing strip and the lower pressure strip are fixedly connected by screws that pass through the upper screw hole, the through hole and the lower screw hole in sequence, and the diameter of the head end of the screw is larger than the diameter of the upper end face of the boss.

[0013] Furthermore, the sealing strip is made of rubber or silicone, and the thickness of the sealing strip is 1-3 mm.

[0014] Compared with the prior art, the utility model has the following beneficial effects: through the cooperation of the upper pressure strip and the lower pressure strip, the lower pressure strip is laid on the lower part of the lower panel, and the upper pressure strip is installed on the upper part of the upper panel, and after being fixed and connected by screws, the stability and connection strength of the overlap of the steel structure roof panel can be greatly improved, providing strong support for the stable construction of the steel structure roof;

[0015] By setting a sealing strip and installing it between the upper panel and the lower panel, the waterproof sealing performance of the connection between the steel structure roof panels can be greatly improved;

[0016] By setting up the diversion groove, the flow and discharge of rainwater can be facilitated to avoid water accumulation on the steel structure roof panel in rainy weather;

[0017] The cone-shaped boss can effectively prevent rainwater from penetrating into the screw hole gap, thus avoiding the rust of the screws and facilitating the subsequent disassembly and installation of the steel structure roof panel.

[0018] By setting the inner notch, the drainage and guidance of the accumulated water can be realized, thereby ensuring that the accumulated water can flow smoothly from the diversion groove, effectively reducing the generation of accumulated water;

[0019] By setting the upper surface of the sealing strip as an inclined surface, rainwater can be effectively prevented from remaining on the upper surface of the upper pressure strip;

[0020] The utility model can not only stably and effectively fix the overlapped joints of the steel structure roof panels, greatly improving the wind resistance of the steel structure roof, but also effectively drain and discharge the accumulated water at the joints of the steel structure roof panels, effectively enhancing the waterproof performance of the steel structure roof; the utility model has a simple structure and is easy to install and use, providing strong support for the construction of the steel structure roof and the subsequent safe use.

[0025] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present invention and are for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0026] Please refer to the instruction manual Figure 1-3 , the utility model provides a technical solution:

[0027] Embodiment 1, a steel structure roof panel bead, including an upper bead 3, a lower bead 8, and a sealing strip 6 installed between the upper bead 3 and the lower bead 8, the lower bead 8 is laid on the lower part of the lower roof panel, in order to improve stability, the lower bead 8 can be welded and fixed on the supporting beam of the steel structure roof, the sealing strip 6 is laid between the lower roof panel and the upper roof panel, the upper bead 3 is laid on the upper part of the upper roof panel, the upper bead 3, the lower bead 8 and the sealing strip 6 are all long strip-shaped plate structures, wherein the upper bead 3 and the lower bead 8 are made of stainless steel, and the sealing strip 6 is The material of the sealing strip 6 is rubber or silicone, and the thickness of the sealing strip 6 is 1-3mm. Both ends of the upper bead 3 and the lower bead 8 are provided with a bend 1 adapted to the steel structure roof panel. The lower surface of the upper bead 3 is provided with a plurality of guide grooves 5 arranged along the axial direction of the upper bead 3 and used for the flow of rainwater. The guide grooves 5 are arranged along the width direction of the upper bead 3, and the rainwater can flow downward along the steel structure roof through the guide grooves 5. The upper surface of the upper bead 3 is provided with a plurality of bosses 4 arranged along the axial direction of the upper bead 3 and having a conical structure. The upper end of the boss 4 is provided with an upper screw hole 2 penetrating the upper bead 3. The upper surface of the sealing strip 6 is provided with several lower screw holes 9 which correspond to the upper screw holes 2 one by one and penetrate the lower strip 8. The upper strip 3, the sealing strip 6 and the lower strip 8 are fixedly connected by screws which pass through the upper screw holes 2, the through holes 7 and the lower screw holes 9 in sequence. The screws can also pass through the lower screw holes 9 and be threadedly connected to the supporting beams of the steel structure roof. The diameter of the head end of the screw is larger than the diameter of the upper end surface of the boss 4. The boss 4 with a conical structure can not only make the upper screw hole 2 higher than the upper surface of the upper strip 3, but also the head end of the screw can cover and shield the upper screw hole 2, thereby effectively preventing rainwater from penetrating into the gap between the upper screw hole 2 and the screw, and preventing the screw and the upper screw hole 2 from being corroded and rusted.

[0028] In the second embodiment, although the guide groove 5 can realize the flow of rainwater, some rainwater will still be blocked by the upper pressure strip 3, and water will accumulate on both sides of the guide groove 5. In order to allow the rainwater to flow out of the guide groove 5 fully and efficiently, a plurality of inner recesses 10 which are arranged axially along the upper pressure strip 3 and are wide on the outside and narrow on the inside are arranged at regular intervals on one side of the upper pressure strip 3.

This allows rainwater on the upper surface of the upper pressure strip 3 to flow downward along the inclined surface 11. Several guide grooves 5 on the lower surface of the upper pressure strip 3 form several protrusions on the upper surface of the upper pressure strip 3. In order to avoid the protrusions affecting the flow of rainwater, the cross-section of the protrusions is an isosceles triangle structure.
