[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0017] like Figure 1 to Figure 2 In the embodiment of the splicing connection device of the steel structure house of the utility model shown, the splicing connection device of the steel structure house includes a connecting tube 1 with openings at both ends, and connecting flanges 2 are welded to the upper and lower ends of the connecting tube 1, and an upper steel column 3 and a lower steel column 4 of H-shaped steel are fixedly connected to the connecting flanges 2 respectively, and a beam connecting part 5 is welded to the side wall of the connecting tube 1, and the beam connecting part 5 is bolted to a steel beam 6 of H-shaped steel, and a web cavity 51 is provided on the beam connecting part 5, and the web of the steel beam 6 is inserted into the web cavity 51.

[0018] Specifically, the H-shaped upper steel column 3 and the lower steel column 4 are fixedly connected to the two ends of the connecting tube 1 respectively, and the beam connecting part 5 with the web cavity 51 is welded on the side wall of the connecting tube 1, and the web of the H-shaped steel beam 6 is inserted into the web cavity 51, and the web of the steel beam 6 is bolted to the beam connecting part 5. The beam connecting part 5 is fixedly connected to the connecting tube 1 to avoid the direct connection between the H-shaped steel beam and the H-shaped steel column. The connection node structure is simple, and the production and construction are easier.

[0019] In one embodiment of the present application, preferably, the upper steel column 3 and the lower steel column 4 are respectively extended from both ends of the connecting tube 1, and the upper steel column 3 and the lower steel column 4 are respectively welded with fixing plates 7 at both ends of the connecting tube 1, and the fixing plate 7 is bolted to the connecting flange 2. The steel column extending into the connecting tube 1 is equivalent to forming a core column in the connecting tube 1, which can enhance the strength of the connection node. The constraint formed by the connecting tube 1 on the steel column also enhances the anti-overturning ability of the steel column.

[0020] In one embodiment of the present application, preferably, the beam connection portion 5 includes two channel steels 52, the groove surfaces of the channel steels 52 face outward, and a web cavity 51 is formed between the webs of the channel steels 52. The web strength of the channel steels 52 is used to resist the shear force of the beam-column node, and a better connection can be formed with the H-shaped steel beam 6.

[0021] In one embodiment of the present application, preferably, both sides of the steel beam 6 are sleeved on the channel steel 52, and the flanges of the steel beam 6 are bolted to the flanges of the channel steel 52, so as to facilitate the connection between the web of the steel beam 6 and the channel steel 52 and between the flanges.

[0022] In one embodiment of the present application, preferably, the height of the steel beam 6 is consistent with the height of the channel steel 52, and the flanges of the steel beam 6 are bolted to the flanges of the channel steel 6 with reinforcing plates 8, and the heightening of the web can improve the stiffness of the connection node of the steel beam 6.

[0023] In one embodiment of the present application, preferably, the cross-section of the connecting tube 1 is rectangular, square, regular polygon or circular. The regular shape of the connecting tube 1 makes it easier to connect the beam connecting part 5 with the connecting tube 1, and facilitates the connection of steel beams 6 in different orientations on the same plane.

[0024] In summary, the steel structure house splicing connection device in the above embodiment of the utility model, specifically, extends the H-shaped upper steel column 3 and the lower steel column 4 into the connecting tube 1, bolts the connecting flanges 2 at both ends of the connecting tube 1 to the fixing plates 7 on the steel columns, welds a beam connecting portion 5 with a web cavity 51 on the side wall of the connecting tube 1, inserts the web of the H-shaped steel beam 6 into the web cavity 51 between the webs of two channel steels 52, and bolts the web of the steel beam 6 to the web of the channel steel 52, and fixes the wing plate of the channel steel 52 to the wing plate of the steel beam 6, and fixes the beam connecting portion 5 to the connecting tube 1 to avoid the direct connection between the H-shaped steel beam and the H-shaped steel column. By adjusting the cross-sectional shape of the connecting tube 1 according to needs, it can also meet the connection of steel beams 6 in different orientations on the same plane. The connection combination is flexible, so that the connection node structure is simple, and production and construction are easier.
