The connecting device is an integrated structure, and the connecting device is located on two adjacent I-shaped steel beams. Between them, the support plates on both sides of the connection device are matched with the through holes of the lower horizontal plate, and the bolts pass through the support plates on both sides of the connection device, and the support plate in the middle of the connection device is the upper part of the two I-beams. At the joint of the horizontal plate, the upper part of the support plate on both sides in the connecting device and the lower part of the horizontal plate of the I-beam beam are all provided with nuts, and the bolts cooperate with the nuts.

As an optimization, a horizontal plate is provided on the upper part of the adjacent I-beam connection, and the bolts pass through the horizontal plate and the horizontal plate is close to the horizontal plate on the upper part of the I-beam, and the vertical plate of the I-beam Several convex edges are arranged on both sides, and the convex edges are arranged equidistantly in sequence, grooves are formed between the convex edges, and the convex edges of the I-shaped steel beams can be plugged and matched with the grooves of the adjacent I-shaped steel beams.

In the utility model, two or more I-shaped steel beams are put together, fixed and matched by connecting devices, and arc-shaped rods are used to form an arched structure, which effectively supports the horizontal plates of the I-shaped steel beams, thereby Keep good load bearing capacity. The connecting parts are fully attached by bolts, which is convenient to use.

detailed description

As shown in Figures 1 and 2, a steel structure beam includes at least two I-shaped steel beams 1 and connecting devices. Each I-shaped steel beam 1 is composed of two horizontal plates and a vertical plate. The horizontal plates at both ends of the steel beam 1 are provided with through holes 9, and a bolt 2 passes through the through holes 9 of the two horizontal plates; each connecting device is composed of three connecting pieces, and each connecting piece is composed of a support plate 4 and two arc rods 3, the two sides of the support plate 4 are fixedly connected to one end of the arc rod 3, and the three connecting parts are fixedly connected through the ends of the arc rod 3 in turn, and the connecting device is an integral structure, and the connecting device is located on the two Between two adjacent I-shaped steel beams 1, the support plates 4 on both sides of the connection device cooperate with the through holes 9 of the lower horizontal plate, and the bolts 2 pass through the support plates 4 on both sides of the connection device, and the middle part of the connection device The support plate 4 is located at the junction of the upper horizontal plates of the two I-beams 1, and the upper part of the support plates 4 on both sides of the connecting device and the lower part of the I-beam 1 horizontal plate are provided with nuts 7 and bolts 2 Cooperate with nut 7. In the utility model, two or more than two I-beams 1 are put together, fixed and matched by connecting devices, and arc-shaped rods 3 are used to form an arched structure, so that the horizontal plates of I-beams 1 are effectively Support, so as to maintain a good load-bearing capacity. The connecting parts are fully adhered to by the bolt 2, which is convenient to use.

In order to further improve the stability, a horizontal plate 5 is provided on the upper part of the joint of the adjacent I-beam 1 described in this embodiment, and the bolt 2 passes through the horizontal plate 5 and the horizontal plate 5 is close to the I-beam 1 the upper horizontal plate. The firmness of cooperation between the adjacent I-shaped steel beams 1 is effectively improved through the horizontal plate 5, and the stability is effectively improved.

Specifically, in order to facilitate the cooperation between the I-beams 1, the two sides of the vertical plate of the I-beam 1 described in this embodiment are provided with several convex edges 6, and the convex edges 6 are arranged equidistantly in sequence, and the convex edges 6 A groove 8 is formed between them, and the convex edge 6 of the I-beam 1 can be plugged and fitted with the groove 8 of the adjacent I-beam 1 . Through the mating of the convex edge 6 and the groove 8, the mating is more convenient and the stability can be improved at the same time.
