Description

Fastener

Technical Field

The utility model relates to the technical field of plate connectors, in particular to a fastener.

Background

When the tiles used for the roof with the steel structure, particularly the tiles with lighter weight such as color steel tiles, are installed, fixing measures are usually needed to avoid the tiles from falling or loosening due to various factors. The fixing measures are generally as follows: firstly, a self-tapping screw directly penetrates through a tile and then is locked with a supporting keel, and a sealing gasket is arranged between the screw and the tile to prevent water; secondly, a connecting piece is locked on the back surface of the tile through a screw (the screw does not penetrate through the tile), and then the connecting piece is locked with the keel; thirdly, steel ropes, clamping plates or other strip-shaped materials are adopted to compress the tiles on the support keels outside, and two ends of the strip-shaped materials are respectively fixed with the support keels or the ground. For the first mode, the supporting keels below the tiles are not usually seen when screws are driven, and workers with insufficient experience easily drive the screws to deflect, so that a certain fixed point of the tiles can be fixed only by driving a plurality of screws, and the attractiveness is affected. For the second mode, the service time is long, and screws for connecting the tiles and the connecting piece are easy to loosen, so that the tiles are not firmly connected; moreover, the second mode often needs to set up a ladder or a scaffold in the house, which is relatively troublesome. For the third mode, all waterproof tiles can be fixed after being installed, the waterproof tiles are not well controlled in arrangement and installation, and the problem of water leakage is possibly caused by overlarge gaps.

Main component symbol description:

the fastener comprises a fastener 10, a fastener body 11, a connecting piece 12, an extension plate 13, a connecting plate 14, a first limiting plate 15, a second limiting plate 16 and a hook 17;

a support keel 20;

tile 30.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent.

As shown in fig. 1 to 3, the present utility model discloses a fastener 10, which includes a fastener body 11. The fastener body 11 comprises an extension plate 13, a connecting plate 14, a first limiting plate 15 and a second limiting plate 16, wherein the connecting plate 14, the first limiting plate 15 and the second limiting plate 16 are sequentially connected and integrally formed, and the extension plate 13 is welded and fixed at the middle position of the connecting plate 14. The connecting plate 14, the first limiting plate 15 and the second limiting plate 16 enclose a clamping groove, and the clamping groove can be in limiting fit with the supporting keel 20. In general, the supporting keels 20 are all made of square tubes, so the shape of the clamping grooves is square which is matched with the shape of the square tubes, and the clamping grooves can be directly inserted into the square tubes. The connecting plate 14 and the second limiting plate 16 can be designed to have a larger width, so that the clamping groove has a larger depth, thereby facilitating a larger adjustment space.

The fastener body 11 may further be provided with a connecting member 12, the connecting member 12 is preferably a bolt, and the first limiting plate 15 is provided with a through hole through which the bolt passes. By arranging the connecting piece 12, the fastener body 11 can be locked on the supporting keel 20, so that the stability of the fastener 10 is further improved, and the tile 30 is ensured to be firmly installed.

At least one hook portion 17 is arranged at one end of the extension plate 13 far away from the connecting plate 14, the hook portion 17 is used for limiting the tile 30, and a notch matched with the hook portion 17 can be formed in the side edge of the tile 30, so that the tile 30 shields the extension plate 13, and the appearance of a roof surface is facilitated. Preferably, the hooks 17 are parallel to each other and the hooks 17 are parallel to the web 14 to facilitate the mounting of the tiles 30 and to provide notches for the hooks 17 to fit when the tiles 30 are prefabricated.

In particular, at least one hook 17 should extend in the opposite direction to the notch of the slot on the extension plate 13 to ensure effective retention of the tile 30, as shown in fig. 1. The number of hooks 17 is greater than one, and at least one of the hooks 17 extends in a direction opposite to the direction in which the other hooks 17 extend, as shown in fig. 2. Typically, one or two hooks 17 are provided for ease of attachment.

When the utility model is used, the fastener 10 arranged on the support keel 20 closest to the ridge can be locked and fixed through the connecting piece 12, and the rest of the fasteners 10 can be in limit fit with the support keel 20 through the clamping groove. Of course, all the fasteners 10 can be locked with the supporting keels 20 through the connecting pieces 12, so that bidirectional limiting can be realized, and the stability is higher.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
