The upper flange, the lower flange and the web are all provided with several through grooves, and the positions of the several through grooves correspond to the positions of the several lower concave plates with the same size.

The card slots are provided on the left and right sides of each of the slot plate groups.

The clamping grooves are provided between two adjacent lower concave plates of the groove plate group.

Two side ends of the upper flange are respectively provided with a channel plate group, and the length of the channel plate group is not greater than 1/3 of the total length of the purlin.

The middle part of the lower flange is provided with the groove plate group, and the length of the groove plate group is not greater than 1/3 of the total length of the purlin.

The groove depth of the lower concave plate is 2-10 mm, and the thickness of the reinforcing strip is smaller than the groove depth of the lower concave plate.

Compared with the prior art, the beneficial effects of the utility model are:

The grooved plate group is set at the load-bearing or easy-to-crack position of the purlin, and each grooved plate group can be detached and connected with reinforcing bars. The purlins are reinforced to increase the load-bearing range of the purlins and make the steel structure of the workshop more stable.

Detailed ways

The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection 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", The orientation or positional relationship indicated by "vertical" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the referred device or element must have a specific Orientation, construction and operation in a particular orientation, therefore should not be construed as limiting the invention.

As shown in Figures 1 to 4, a purlin that is easy to reinforce includes a web 1, an upper flange 2 and a lower flange 3, and the upper flange 2 and the lower flange 3 are respectively connected to the upper and lower ends of the web 1, The upper flange 2, the lower flange 3 and the web 1 are connected with one or several groove plate groups, and the groove plate groups are arranged at the load-bearing or easy-to-crack places of the purlins to facilitate the later installation of the reinforcement bars 5.

Each groove plate group includes one or several lower concave plates 4, and the lower concave plates 4 of each groove plate group are aligned and arranged in the transverse direction, and each groove plate group is inserted with reinforcing strips 5 transversely; Both ends of the concave plate 4 and the lower concave plate 4 are upturned and connected to the purlin plate body, and a groove for the reinforcing bar 5 to pass is formed in the middle, and the lower concave plate 4 and the purlin plate body are connected by welding or integrally formed.

The upper flange 2, the lower flange 3, and the web 1 are also provided with one or several card slots 6, and the reinforcing bar 5 is provided with a buckle bar 7 that cooperates with the card slots 6; the reinforcing bar 5 passes through the concave Behind the plate 4, the buckle strip 7 is snapped into the slot 6 to prevent the reinforcement strip 5 from sliding, and the reinforcement strip 5 is flexible and convenient to install and has a stable structure.

The upper flange 2, the lower flange 3 and the web 1 are all provided with several through grooves 8, and the positions of the several through grooves 8 correspond to the several lower concave plates 4 one by one, and the sizes are the same. The through groove 8 is used to avoid water accumulation and reduce the overall weight of the purlin.
