Detailed Description

Referring to fig. 1, the present invention relates to a steel structure corridor, which comprises:

the steel members are mutually intersected and obliquely intersected in the central area of the same tie bar 2, and the outer ends of the steel members are respectively intersected at two sides of the tie bar 2 adjacent to the frame;

and the steel columns 1 are perpendicular to the peripheral surface of the frame.

The utility model discloses include the frame, the frame embeds has tie rod 2 and the steel member that is used for the support, wherein, tie rod 2 cuts apart the frame inside and forms a plurality of support spaces, the steel member adopts the direction slant handing-over that each other does not intersect in same tie rod 2's central zone, then, tie rod 2, the horizontal load that the steel member bore can evenly distributed on the frame, namely through adopting tie rod 2, the steel member is for making the concentrated stress that receives on the frame keep even, and then the structure of frame can highly obtain the promotion, can understand, improved the frame and suffered the upper limit of fatigue failure, the vestibule has obtained simplification structurally for prior art, and then has shortened installation time;

in the specific implementation, a canopy is built on the frame at the uppermost layer and used for shielding rainwater, the frame at the next layer is used for people to walk, and certainly, a bottom plate is erected on the frame at the next layer;

in the concrete implementation, the tie bars 2 in the two adjacent supporting spaces are in an X shape, and the design is to quickly release the horizontal load onto the frame, so that the structure is more stable, and the load bearing capacity is larger.

Further, the inclination directions of the steel members in the support space intersect with each other; by adopting the scheme, the load of the steel member is transmitted to the tie bars 2, in the specific implementation, the steel members in two adjacent supporting spaces are inclined to the same tie bar 2, two ends of the tie bar 2 penetrate through the frame, the tie bar 2 and the frame are locked by screws, the load borne by the first supporting space acts on the frame and the tie bar 2, the tie bar 2 plays a role in pulling the frames towards each other, the steel member plays a role in supporting, and the intersection of the frame and the steel member is far away from the intersection of the inclination directions of the two steel members.

Further, the central region of the tie bar 2 has a support cross node 3, and the ends of the steel member intersect at the support cross node 3; the installation of being convenient for, constructor can find central zone fast and assemble the steel member, simultaneously, in this embodiment, the surface area of supporting cross node 3 is greater than the area of two steel members, then, can make the frame bear bigger load.

As shown in fig. 4, further, the steel member includes two angle steels 5 distributed in an array and clamping reinforcing nodes 4; by adopting the scheme, the two angle steels 5 are connected, the prestress generated by directly welding the two angle steels 5 is reduced, the length of a welding seam is reduced, and the prestress concentration of the structure caused by welding is protected.

Furthermore, the frame is formed by connecting a plurality of steel beams 6 end to end, edge supporting nodes 7 are arranged at the intersection of the two steel beams 6, and the edge supporting nodes 7 are uniformly laid on the peripheral surface of the intersection of the two steel beams 6; two girder steels 6 connect and form concentrated load department, through set up border support node 7 at the crossing between two girder steels 6, prevent that two girder steels 6 from warping because of stress concentration.

Further, the steel column 1 is I-shaped steel, and a stiffening plate 8 is embedded in the I-shaped steel;

in this embodiment, the stiffening plates 8 are inclined, and of course, the stiffening plates 8 may be placed horizontally, so that the load of the steel beam 6 can be better transmitted to the steel column 1, and the structural load is distributed more uniformly and the structural stability is better.

As shown in fig. 2-3, further, a flat steel 10 with a reinforcing plate 9 is included, the ends of the flat steel 10 are respectively connected with the steel columns 1, and the reinforcing plate 9 is connected with the side surface of the steel beam 6; for distributing the load on the tie bars 2 and quickly releasing it to the steel columns 1, thereby making the structure more stable and the load-bearing capacity greater.

The above embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by the technical solution of the present invention by those skilled in the art are all within the scope of the present invention as defined by the claims.
