Technical field
The utility model relates to beam-column connection in a kind of steel work, particularly a kind of novel cold-formed rectangular tube-steel column and H section steel beam assembling end plate connecting node.
Background technology
Existing rectangle steel tubing string is connected with the node of H shaped steel and mainly comprises common internal partition formula connection, the through connection of dividing plate, strengthens board-like connection of outer shroud or the like.But, these joint forms all exist certain shortcoming, as common internal partition formula connected node structure more complicated, dividing plate is arranged, may bring difficulty to concrete casting, can not guarantee the quality of placing of concrete, the processing node need interrupt steel pipe column just can carry out the construction of internal partition, the field Welding workload is big, the difficult control of construction quality; 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 purpose of this utility model provides a kind of novel cold-formed rectangular tube-steel column and H section steel beam assembling end plate connecting node, solve that conventional node connects that on-the-spot secondary welding increases because the defective that welding is introduced, join domain has internal partition to increase the technical problem of the difficulty that the post inner concrete builds; And the outstanding problem that increases the finishing difficulty and influence architectural effect of solution node region.
For achieving the above object, the utility model adopts following technical scheme:
A kind of novel cold-formed rectangular tube-steel column and H section steel beam assembling end plate connecting node, comprise girder steel and steel column, described girder steel is the H section steel beam, described steel column is a cold-formed rectangular tube-steel column, described steel column outer wall is being socketed with square casing with girder steel connecting position place, steel column, square casing is connected with prepackage beam head member by bolt A, the main body of described prepackage beam head member is the cross section H shaped steel consistent with girder steel, its the inner is connected with end plate, the two ends of described end plate are stretched out the upper and lower surface of prepackage beam head member and are connected by bolt with steel column with square casing, described end plate stretches out the external surface of prepackage beam head member part and the angle position of the formation between the prepackage beam head member body is welded with floor, dock with girder steel the outer end of prepackage beam head member, the butt joint place is stamped cover plate, is connected by bolt B between cover plate and the girder steel and between cover plate and the prepackage beam head member.
Described cover plate is positioned at top flange end face seam crossing, bottom surface, bottom flange seam crossing and web two side seams of girder steel and prepackage beam head member.
Described square casing is the combined steel pipe that square shaped steel steel pipe or steel plate are spliced into.
Described square casing end face and underrun fillet weld and column outer wall are welded to connect, and square casing is connected by plug welding with the outer wall that post is positioned at sleeve pipe.
Described floor is triangle steel plate, rectangular steel plates, hexagon steel plate or angle steel.
Described steel column, square casing, end plate correspondence position all have bolt hole, have the plug welding hole on the described sleeve pipe, bolt hole on the sleeve pipe and plug welding hole staggered arrangement.
Compared with prior art the utlity model has following characteristics and beneficial effect: 1) owing in the node region internal partition is not set, pillar elongated (three to four layers, about 10m) need not to block adding man-hour; Can free concrete perfusion and guarantee quality, can improve the rigidity and the bearing capacity of pillar so effectively.
2) node section member prefabrication has been avoided the weld job of job site, the fire that reduces the quality accident that causes because of weld defect and cause because of welding spark, and this node connects on-the-spot do not have overhead welding, face down bonding, easy construction simultaneously.
3) compare board-like connection of outer shroud with reinforcement, cross section, node place equates not have and give prominence to substantially with beam, and profile satisfies transportation and architectural space requirement.
4) end plate prepackage beam head member can transmit shearing force owing to be provided with floor, can not need between the web of H shaped steel and the square steel tube post to connect, and has simplified technology when guaranteeing reliable the connection.
5) H shaped steel end plate prepackage beam head member is compared with existing L type angle steel, and the energy force rate opposing vertical forces of opposing horizontal pull, pressure is bigger, and pre-installs the less safety of having guaranteed connection of sled power that beam head component ends causes at end plate.
6) processing technology of overcoat tubular type node is simple, and it is convenient to remedy bolt when high-strength bolt lost efficacy, and force mechanism is clearer and more definite, but mass production.
The utility model has overcome the joint structure complexity, cause post concreting difficulty and the shortcoming that influences architectural appearance and finishing etc. easily, solved by the standardization preprocessing component, reduced or avoid on-the-spot welding, realized the technical problem of freely pouring into of post inner concrete.
The utility model can be widely used in the rectangle steel tubing string and be connected with H section steel beam assembling type node.
