Detailed Description

The following description of the embodiments of the present utility model will be made more apparent and fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by one of ordinary skill in the art without undue burden on the person of ordinary skill in the art based on embodiments of the present utility model, are within the scope of the present utility model.

In the description of the present utility model, it should be noted that the terms "upper," "lower," "left," "right," "top," "bottom," "inner," "outer," "horizontal," "vertical," and the like, as used herein, refer to an orientation or positional relationship based on that shown in the drawings, merely for convenience of description and to simplify the description, and do not denote or imply that the apparatus or elements referred to must have a particular orientation, be configured and operated in a particular orientation, and thus should not be construed as limiting the present utility model.

As shown in fig. 1 to 4, a purline convenient to consolidate, including web 1, top flange 2 and bottom flange 3 connect the upper and lower both ends of web 1 respectively, and top flange 2, bottom flange 3 and web 1 all are connected with one or a plurality of frid group, and frid group locates the bearing or the easy fracture department of purline for make things convenient for later stage installation reinforcement strip 5.

Each groove plate group comprises one or a plurality of concave plates 4, the concave plates 4 of each groove plate group are aligned and arranged along the transverse direction, and each groove plate group is transversely penetrated and inserted with a reinforcing strip 5; through setting up a plurality of concave plates 4, concave plate 4's both ends upwarp connect purlin slat body, form the recess that is used for strengthening strip 5 to pass in the centre, concave plate 4 is welded mode connection or integrated into one piece with purlin slat body down.

The upper flange 2, the lower flange 3 and the web plate 1 are also provided with one or a plurality of clamping grooves 6, and the reinforcing strip 5 is provided with a clamping strip 7 which is matched and buckled with the clamping grooves 6; after the reinforcing strip 5 passes through the concave plate 4, the clamping strip 7 is clamped into the clamping groove 6, the reinforcing strip 5 is prevented from sliding, the reinforcing strip 5 is flexibly and conveniently installed, and the structure is stable.

The upper flange 2, the lower flange 3 and the web plate 1 are all provided with a plurality of through grooves 8, and the positions of the through grooves 8 and the concave plates 4 are in one-to-one correspondence and have the same size.
