Technical Field
The invention relates to the technical field of construction of steel structures and cables, in particular to a steel structure node and a construction method thereof when a cable penetrates through a steel beam.
Background
Due to the fact that steel structures develop rapidly, structural forms are more and more complex, unit types in the same structure are complex and various, due to the fact that different unit types are different in characteristics and construction methods, collision or influence between the structures or actual construction is difficult to avoid, and cable units are tensioned in advance in actual use, cables are generally in a straight state under most conditions, and other structures or rod pieces cannot exist at positions where the cables pass through.
At present, generally in curtain wall construction, the cable structure can collide with the major structure, and the cable is vertical arrangement under most circumstances, and the crossing position with the roof beam only can avoid colliding at the beam flange trompil, and when arranging to other states, the trompil probably influences the girder steel bearing capacity, but some places can not avoid cable and other component to collide or produce the influence each other, and because local influence probably leads to the girder steel to connect the cross-section to do very big, and then influences the whole aesthetic property of steel construction and even the design layout.
Disclosure of Invention
The invention aims to overcome the defects and provides a node structure which does not affect a steel structure and a cable and a construction method thereof.
In order to achieve the above object, the present invention is realized by:
a steel structure node when a cable passes through a steel beam comprises a node body (1) projected to be C-shaped, a node closing part (2), a variable cross-section part (3) and a steel beam node part (4); wherein, node body (1), node closure spare (2), become section spare (3), girder steel node spare (4) are box girder construction, and node closure spare (2) set up the opening part at node body (1) and make its closed loop, become section spare (3) and set up the both ends at node body (1), and girder steel node spare (4) are connected with the section spare (3) that become at both ends respectively.
The construction method of the steel structure joint when the cable passes through the steel beam comprises the following steps
and 4, installing a node closing piece (2) at the opening of the node body (1) and closing the opening of the node body (1).
According to the construction method of the steel structure node when the cable penetrates through the steel beam, the node closing part (2) is installed after the cable is in place or is pre-tensioned, and then the node closing part plays a reinforcing role on the node body (1).
The steel structure node when the cable passes through the steel beam has the advantages that the opening of the node body (1) ensures that a single or a plurality of cables and anchorage devices thereof can pass through.
At present, steel structure system types are complicated various, single type structure can't satisfy current demand, and cable structure generally is used for the roofing system at present stage, generally does the connected node on top layer post or roof beam (there is cable structure in some curtain wall structures, cable vertical distribution under the general condition, only can at the beam flange trompil), consequently considers cable structure and other steel structure types (like frame construction) to combine the use, receives the force jointly with the atress component part of cable structure as other structures, full play different structure system's advantage.
The node method provided by the invention can effectively solve the collision conflict between the cable and the beam, reduce the construction difficulty and ensure that the construction and the actual use of the beam and the cable structure have no influence on each other. In addition, the method can effectively solve the problems of structural type singleness and limitation, and can perfectly fuse a cable structure system into a steel structure system.

Detailed Description
The invention is further illustrated by the following specific examples.
Example one
As shown in fig. 1 and 2, a steel structure node when a cable passes through a steel beam comprises a node body (1) projected to be in a 'C' shape, a node closing part (2), a variable cross-section part (3) and a steel beam node part (4); wherein, node body (1), node closure spare (2), become section spare (3), girder steel node spare (4) are box girder construction, and node closure spare (2) set up the opening part at node body (1) and make its closed loop, become section spare (3) and set up the both ends at node body (1), and girder steel node spare (4) are connected with the section spare (3) that become at both ends respectively.
The construction method of the steel structure joint when the cable passes through the steel beam comprises the following steps
and 4, installing a node closing piece (2) at the opening of the node body (1) and closing the opening of the node body (1).
According to the construction method of the steel structure node when the cable penetrates through the steel beam, the node closing part (2) is installed after the cable is in place or is pre-tensioned, and then the node closing part plays a reinforcing role on the node body (1).
The steel structure node when the cable passes through the steel beam has the advantages that the opening of the node body (1) ensures that a single or a plurality of cables and anchorage devices thereof can pass through.
Example two
As shown in fig. 3 and 4, on the basis of the steel structure node disclosed in the first embodiment, the steel structure node through which the cable passes according to the present invention can also be used in a cross form, specifically as follows:
