Abstract
The utility model discloses a round steel tube supporting structure comprising a plurality of round steel tubes which are mutually fixed and connected to form the supporting structure, wherein the supporting structure is a pull rod structure which comprises three round steel tubes, a supporting and connecting pitch point plate and arc-shaped blocking plates, a long groove opening matched with the supporting and connecting pitch point plate is formed in the round steel tube I, the ends of the round steel tubes I, II and III, where the supporting and connecting pitch point plate passes through, are respectively arranged and fixed at the two ends of the supporting and connecting pitch point plate in a sleeve manner, and the arc-shaped blocking plates are arranged at the ends of the round steel tubes II and III, connected with two ends of the supporting and connecting pitch point plate. The steel structure round-tuber-shaped section is symmetrical, the section centroid is in coincidence with the shear center, and section moment of inertia for each axis is same; the section is closed, anti-torsion stiffness is big, plate member partial stability is good; the round steel tube supporting structure is simple and direct and smooth in appearance, bar members can be directly welded at a same point, pitch plates can be omitted, and steel material is saved; and compared with an open section, the round tube section has the advantages of being flat and neat in surface, free of dead angles, small in outer surface area, favorable for saving anti-corrosion and fireproof coating, and also favorable for dust removal.
Description
Technical field
The utility model belongs to supporting member, is specifically related to a kind of round steel pipe braced structures.
Background technology
Support system is that steel using amount is less relatively in the steel work, effect and very huge system's ingredient.It mainly acts on: form unified integral body with roof girder, transmit the roofing horizontal loading; Form firm longitudinal member with frame column, guarantee the stability of skeleton of building, provide, strengthen longitudinal rigidity; Reduce the outer calculated length of steel column face; Transmit the wind load of gable; The transferring structure seismic forces.
Frame construction and high-rise steel structure supporting rod adopt H shaped steel more, and the supporting member of portal frame structure, pylon structure adopts rolled section steel such as angle steel, channel-section steel more, with just amount is many, be unfavorable for the saving of steel, and rigidity are little.
The utility model content
In order to overcome the problems referred to above that the prior art field exists, the purpose of this utility model is, a kind of round steel pipe braced structures is provided, and it is low to solve existing steel work supporting member rigidity, the problem of consumption waste.
The round steel pipe braced structures that the utility model provides, it comprises some round steel pipe, the described some round steel pipe formation braced structures that is mutually permanently connected.
Described braced structures is Tiebar structure, described Tiebar structure comprises three round steel pipe, support and connection gusset plate, arc shutoff plate, described round steel pipe I is provided with the long rabbet that cooperates with the support and connection gusset plate, the support and connection gusset plate passes round steel pipe I, the end of round steel pipe II, round steel pipe III is set with on the two ends that are fixed on the support and connection gusset plate, and the fixing end in round steel pipe II, round steel pipe III and support and connection gusset plate two ends is provided with arc shutoff plate.
Described braced structures is pillared trussed construction, described pillared trussed construction comprises that pillared truss is responsible for, pillared truss arm, one end of described pillared truss arm is fixedly connected on pillared truss and is responsible for, and pillared truss arm is arc intersection shape with the end that the pillared truss person in charge is connected.
Described braced structures is that biplate supports person in charge's structure, and described biplate supports person in charge's structure and comprises a pair of support person in charge, web member, and described web members fixed is arranged between a pair of support person in charge, and the web member two ends are to be arc intersection shape.
The round steel pipe braced structures that the utility model provides, its beneficial effect be, this steel work tubular cross section symmetry and the cross section centre of form and cut the heart and overlap, and second moment of area is identical to each; The cross section closure, torsional rigidity is big, plate is local stablizes; Outward appearance is simple and direct, level and smooth, and rod member can be directly welded in same point, can be without gusset plate, to save steel; Compare opening section, the pipe cross section has characteristics such as surfacing, no dead angle and external surface area are little, is conducive to save anticorrosion and fireproof paint, also is convenient to dedusting.
