Abstract

The utility model provides a novel outer sleeve tube type connecting node of a cold-bending rectangular steel tube column and an H-shaped steel girder. The novel outer sleeve tube type connecting node of the cold-bending rectangular steel tube column and the H-shaped steel girder comprises the tube column, the steel girder and a tube sleeve, wherein the tube sleeve is connected outside the tube column in a sleeved mode and is fixed with the tube column, the cross sectional area of the steel girder is in an H shape, the steel girder comprises two longitudinal girders and a cross girder, and the two longitudinal girders and the cross girder are all perpendicular to the outer surface of the tube sleeve. According to the scheme, a separation board is removed, the tube column can be arranged to be with any lengths according to needs, and cut-off is not needed during fabrication. Meanwhile, quality can be ensured when concrete pouring is carried out, and therefore rigidity and bearing capacity of a column can be effectively improved. Meanwhile, a pre-fabrication part of the node can be produced in a batch mode in a factory section production line, a fabricating process of a plate of the node is simple, and the appearance of the node meets transportation requirements and building space requirements. When the novel outer sleeve tube type connecting node of the cold-bending rectangular steel tube column and the H-shaped steel girder is used, the concrete can be poured freely.

Description

Novel cold-formed rectangular tube-steel column and H section steel beam overcoat tubular type connected node
Technical field
The utility model relates to technical field of buildings, refers to a kind of novel cold-formed rectangular tube-steel column and H section steel beam overcoat tubular type connected node especially.
Background technology
In the prior art, before concreting, need rectangle steel tubing string and H shaped steel are linked together by connected node.Existing connected node connects and mainly comprises: common internal partition formula connection, the through connection of dividing plate, the board-like connection of reinforcement outer shroud etc.All there is certain defective in these joint forms at aspects such as working procedure, construction qualities.
Internal partition formula connected node structure more complicated, and dividing plate need be set, may bring difficulty to concrete casting, can not guarantee the quality of placing of concrete.Processing node simultaneously needs steel pipe column interrupted just and can carry out the construction of internal partition, and on-the-spot welding job amount is big, the difficult control of construction quality.And dividing plate and junction, girder steel edge of a wing post jamb through twice welding after, residual stress is bigger, and brittle fracture takes place easily.
The size of strengthening the board-like connection outer annular-stiffer of outer shroud is bigger, especially less owing to the concrete filled steel tube column section in the concrete filled steel tube dwelling house, when the size of outer heavier-duty node ring flat-plate is bigger, make troubles often for architectural processing, interior has considerable influence to dwelling house.
The utility model content
The technical problems to be solved in the utility model provides a kind of structure novel cold-formed rectangular tube-steel column more reasonable and easy to use and H section steel beam overcoat tubular type connected node.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of novel cold-formed rectangular tube-steel column and H section steel beam overcoat tubular type connected node, comprising: tubing string, girder steel, pipe box; Wherein said pipe box is socketed in outside the tubing string and is fixed together; Described girder steel cross-sectional area is H shape, comprises two longerons and a crossbeam; Described two longerons and crossbeam all are vertically fixed on the external surface of described pipe box.
Wherein, this novel cold-formed rectangular tube-steel column and H section steel beam overcoat tubular type connected node also comprise shear connector, described shear connector comprises two fixed heads, described two fixed heads are separately fixed at the both sides of described crossbeam, and the external surface of the end of described two fixed heads and described pipe box is fixed.
Wherein, described two fixed heads are provided with the screw that runs through plate body, and also are provided with suitable screw on the described crossbeam and are fixed together with the crossbeam by bolt and described girder steel.
Wherein, the wall of described pipe box is provided with a plurality of plug weldings hole to weld together with tubing string.
Wherein, this pipe box is welded by four steel plates; The cross section of described tubing string is that rectangle and four corners are fillet; Described tubing string is socketed in the described pipe box, and described four corner locations and pipe box welding.
Wherein, described tubing string is cold-formed rectangular tube-steel column.
The beneficial effect of technique scheme of the present utility model is as follows:
Cancelled dividing plate in the such scheme, and tubing string can be arranged to random length (for example three to four floor rooms, one endowel, general about 10 meters of length) as required, and need not man-hour to block adding.Simultaneously quality can be when concreting, guaranteed, rigidity and the bearing capacity of pillar can be improved so effectively.Simultaneously, the preprocessing of node part can be produced in batches on factory's section production line, node plate processing technology simple and the satisfied transportation of profile and architectural space requirement.In use can free concrete perfusion.
