Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of skylight strips, in particular to a novel self-waterproof board-type skylight strip. Background Art
[0002] With the development of society, the concepts of green, intensive and ecological have gradually gained popularity, and construction has also paid more and more attention to safety, environment and civilization. How to improve the safety and reliability of waterproofing of steel structure workshop roof has become one of the important goals of modern construction.
[0003] At present, steel structure roofs must meet both waterproofing requirements and lighting requirements. The industry currently adopts a roof metal plate + light strip (3 pieces) + roof metal plate structure. Metal edge banding is added on both sides of each light strip, and adjacent light strips are connected together through metal edge banding to achieve the purpose of waterproofing.
[0004] When the area of the steel structure roof is larger, the demand for lighting also increases accordingly. Therefore, the area of the skylight on the roof increases accordingly. The adjacent skylights are connected by metal edge banding, so the consumption of metal edge banding will also increase significantly, resulting in increased costs. In addition, the metal edge bands between adjacent skylights are connected together by riveting because the materials of the metal and the skylight are different. The stresses they bear are different. After long-term sunlight exposure, the skylight at the riveted joints are prone to cracking, which in turn reduces the waterproof performance and causes roof leaks. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a novel self-waterproof plate-type skylight, which can save the use of metal edge strips, reduce costs, and at the same time avoid cracking of the skylight and the metal edge strips, thereby improving the waterproof performance.
[0006] The utility model is realized through the following technical solutions:
[0007] A new type of self-waterproof plate-type skylight belt is provided, comprising two end skylight belts and a middle skylight belt located between the two end skylight belts, wherein the skylight belts are connected in sequence side by side at the long sides in the length direction, and both long sides of the middle skylight belt are bent to form middle overlapping grooves with openings facing downwards, and the middle skylight belt is provided with a plurality of water diversion grooves with openings facing downwards between the two middle overlapping grooves at intervals along the width direction, and the height of the water diversion grooves is lower than the height of the middle overlapping grooves; the long side of the end skylight belt facing the middle skylight belt is bent to form an end overlapping groove with openings facing downwards, and the end overlapping groove of the end skylight belt is buckled and overlapped with the middle overlapping groove of the middle skylight belt, and butyl waterproof tape is provided at the overlapping portion between the end overlapping groove and the middle overlapping groove.
[0008] Furthermore, both the middle overlapping groove and the end overlapping groove are arc-shaped grooves, and the inner wall of the middle overlapping groove is buckled on the outer wall of the end overlapping groove.
[0009] Furthermore, the height difference between the middle overlapping groove and the water diversion groove is 2-3 cm.
[0010] Furthermore, the other long side of the end light strip is connected to a metal edge strip that can be connected to the roof metal plate, and the end light strip is formed with multiple downward-opening water diversion grooves between the metal edge strip and the end lap groove at intervals along the width direction.
[0011] Beneficial effects of the utility model:
[0012] The utility model forms overlapping grooves on both sides of the middle light belt and the side opposite to the end light belt, so that the middle light belt and the end light belt overlap and buckle with each other through the overlapping grooves, forming a naturally waterproof structure, and setting a top waterproof tape inside the overlap to further reduce the entry of water vapor and improve the waterproof effect. The overall structure is simple, easy to install, high in installation efficiency, and low in later maintenance costs.
[0013] The use of metal edge banding strips on the middle light belt and the end light belt is significantly reduced, which can greatly reduce the cost. At the same time, it can also avoid the problem of cracking at the riveted joints of the light belt due to different stresses caused by different materials between the metal edge banding strip and the light belt, thereby increasing the service life of the light belt and improving its waterproof performance.

[0018] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.
[0019] A new type of self-waterproof board-type light belt, including two end light belts 1 and a middle light belt 2 located between the two end light belts 1. The number of the middle light belts 2 can be increased according to actual conditions, and can be 2, 3 or even more. The middle light belts 2 are also overlapped with each other, and each light belt is connected in sequence side by side at the long sides in the length direction. The long sides on both sides of the middle light belt 2 are bent to form a middle overlapping groove 21 with an opening facing downward. The middle light belt 2 is formed with a plurality of middle water grooves 22 with an opening facing downward between the two middle overlapping grooves 21 at intervals along the width direction, and the height of the middle water grooves 22 is lower than the height of the middle overlapping grooves 21; the height difference between the middle overlapping grooves 21 and the middle water grooves 22 is 2-3 cm. In this embodiment, the height of the middle overlapping groove 21 and the end overlapping groove 11 are both set to 3 cm.
[0020] The middle water trough 22 and the end water trough 11, which are respectively arranged in the middle of the middle light belt 2 and the middle of the end light belt 1, are used to separate rainwater to prevent a large amount of rainwater from being deposited on the light belt, which is not easy to evaporate and easily penetrates into the gap and enters the house. The water diversion trough is used to separate the rainwater so that it cannot be gathered together, which can accelerate the evaporation of rainwater and help to divert rainwater. At the same time, the raised water diversion trough can increase the collision area with the rainwater, which helps to disperse the rainwater and prevent the rainwater from penetrating into the connecting gaps of the light belts after concentration.
[0021] The long side of the end light belt 1 facing the middle light belt 2 is bent to form an end overlapping groove 11 with an opening facing downward. The end overlapping groove 11 of the end light belt 1 is buckled and overlapped with the middle overlapping groove 21 of the middle light belt 2. The middle overlapping groove 21 and the end overlapping groove 11 are both arc-shaped grooves. The inner wall of the middle overlapping groove 21 is buckled on the outer wall of the end overlapping groove 11. Butyl waterproof tape 3 is provided at the overlapping portion of the end overlapping groove 11 and the middle overlapping groove 21.
[0022] The other long side of the end light strip 1 is connected with a metal edge band 13 that can be connected with the roof metal plate, and the end light strip 1 is formed with a plurality of end water grooves 12 with downward openings between the metal edge band 13 and the end lap groove 11 at intervals along the width direction. The metal edge band 13 of the end light strip 1 can be connected with the edge band on the metal roof.
[0023] The utility model bends the long sides of both sides of the middle light belt 2 to form a middle overlapping groove 21 which is 2 to 3 cm higher than the middle water dividing groove 22, and at the same time bends the long sides of one side of the end light belts 1 on both sides to form end overlapping grooves 11 of the same height, so that the long sides of both sides of the middle light belt 2 are respectively overlapped and buckled with the long sides of one side of the end light belt 1 through the two overlapping grooves, forming a naturally waterproof structure. The butyl waterproof tape 3 is arranged in the middle of the overlapping position to effectively prevent water vapor from entering, thereby greatly improving the waterproof performance, and improving the installation efficiency and reducing the later maintenance cost.
