Description

Technical Field

[0001] The utility model relates to the technical field of purlins, in particular to an anti-corrosion purlin matched with FRP skylight tiles. Background Art

[0002] Purlin is an important component of building structure, mainly used to support roof coverings (such as tiles, metal plates or asbestos tiles, etc.) and roof panels, connecting roof trusses or rafters with walls or beams. In modern buildings, purlins are made of materials such as steel, aluminum or precast concrete, depending on the design and functional requirements of the building. When installing FRP skylight tiles, purlins are often required.

[0003] In the Chinese patent application number 201920310760.0, an anti-corrosion purlin for use with FRP skylight tiles is disclosed. The disclosed anti-corrosion purlin describes that "through the setting of the clamping block and the clamping groove, the purlin body has the function of mutual clamping when in use. By flipping the connecting block, multiple groups of purlin bodies are spliced, which provides convenience for subsequent welding, so that the purlin body remains in a horizontal state, and effectively reduces the deviation during welding." Although it can improve the welding accuracy of the two purlin bodies, the clamping block is fixed at the end of the purlin body and is not easy to replace. During assembly, the clamping block on the outermost purlin body protrudes outward, affecting the overall aesthetics. In addition, it is more troublesome to flip the connecting block and then tighten it with screws. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] Figure 1 It is a schematic diagram of the overall structure of the utility model, and combined with Figure 2 and Figure 5 As shown, the anti-corrosion purlin matched with the FRP skylight tile includes a purlin body 1 and a docking block 2. The outer wall of the purlin body 1 is fixed with an anti-corrosion layer 5, and the anti-corrosion layer 5 can be an epoxy coating layer or a hot-sprayed zinc layer or a polyvinyl chloride coating layer or other, which is intended to prevent or slow down the occurrence of corrosion of the purlin body 1 and extend the service life of the purlin body 1. The upper end surface of the purlin body 1 is provided with a groove 4 along the length direction, and a clamping component 3 is provided in the groove 4, and a docking groove 6 is opened at the end of the purlin body 1, and a fixing block 7 is fixed inside the docking groove 6. The docking block 2 is inserted and matched with the docking groove 6, and the length of the docking block 2 is equal to twice the distance from the fixing block 7 to the nearest end of the docking groove 6, so that after the two purlin bodies 1 are docked using the docking block 2, the docking block 2 can be completely covered.

[0030] In addition, see Figure 2 and Figure 4 As shown, a plug post 8 is fixed to the outer wall of the fixing block 7, and slots 9 are provided at both ends of the docking block 2. The plug post 8 is inserted and matched in the slot 9, and the length of the plug post 8 does not exceed half the length of the docking block 2.

[0031] Specifically, when two purlin bodies 1 are butt-jointed, half of the butt-jointing block 2 can be firstly embedded into the butt-jointing groove 6 at the end of one of the purlin bodies 1, and then the end of the other purlin body 1 can be sleeved onto the other half of the butt-jointing block 2.

[0032] When the docking block 2 connects the two purlin bodies 1, the plug posts 8 on the fixing block 7 can be inserted into the slots 9, which can ensure the stability and accuracy of the docking, facilitate subsequent welding operations, and reduce the occurrence of skew.

[0033] In addition, the docking block 2 is detachably arranged in the docking groove 6, which is convenient for subsequent replacement. Secondly, when the FRP skylight tile is installed, the docking block 2 at the end of the outermost purlin body 1 can be removed to avoid bulging outward, thereby increasing the overall aesthetics.

[0034] In a specific embodiment of the present invention, refer to Figure 3 As shown, the clamping assembly 3 includes:

[0035] A connecting post 33, the connecting post 33 is fixed to one end of the inner wall of the groove 4;

[0036] A movable plate 31, one end of which is provided with a through hole 34, and the movable plate 31 is sleeved on the outside of the connecting column 33 through the through hole 34;

[0037] A limiting groove 35, which is provided at the other end of the lower end surface of the movable plate 31;

[0038] The limiting column 32 is fixed to the inner wall of the groove 4 and is away from one end of the connecting column 33 . The diameter of the limiting column 32 is equal to the width of the limiting groove 35 .

[0039] Through the above technical solution:

[0040] After the two purlin bodies 1 are connected by the docking block 2, the movable plate 31 hinged to the outside of the connecting column 33 can be rotated so that the limiting groove 35 provided on the movable plate 31 is sleeved on the outside of the limiting column 32, which can further improve the stability of the docking connection of the two purlin bodies 1, avoid skewing during welding, and ensure the welding quality.

[0041] Furthermore, rubber pads 36 are fixed to the bottom ends of both side walls of the limiting groove 35 , and the upper and lower ends of the rubber pads 36 are integrally formed into arc-shaped transition surfaces.

[0042] Specifically, when the movable plate 31 is rotated to be sleeved on the limiting column 32, the limiting column 32 first squeezes the rubber pad 36, and the rubber pad 36 is compressed. After rotating to the innermost end of the limiting groove 35, the rubber pad 36 returns to its original state, which can block the limiting column 32. When there is no external force, the movable plate 31 is not easy to fall off.

[0043] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
