The specific embodiment
See Fig. 1,2, the prefabricated assembling queen post steel structure of housing that relates to for the utility model.This queen post steel structure of housing comprises twin columns unit 1, and 1 of twin columns unit connects by Vierendeel girder 2, and a described twin columns unit 1 comprises between two steel column 5, two steel columns 5 that can regulate mutual spacing and connecting by girder steel 6, establishes lateral resistant member 3 in the twin columns unit 1.Steel column 5 and Vierendeel girder 2 all adopt welding or rolling H shaped steel.The twin columns unit of forming with two steel columns 1 replaces traditional single structural column, can reduce the sectional dimension of post like this, and the size of post can keep coordinating with wall thickness.In addition, distance between two single-columns, can adjust within the specific limits according to the needs that building is arranged, can satisfy the needs that house building plane is cut apart flexibly, and needing wall dislocation or the post net can not positions aligning originally, by adjusting the distance of these two pillars, Vierendeel girder 2 is all alignd with adjacent post at the both direction on plane.Like this, can satisfy the flexible topology of architectural plane, can satisfy the regular layout of structural element again, bring bigger flexibility for building and structure design.
Twin columns unit 1 is arranged with the room layout of building requirements and is coordinated.Simultaneously, all striven for a post as far as possible, made the load of beam directly pass to the basis, avoided the beam column dislocation by post at each beam-ends.
Can use preferred modulus, architectural plane is arranged on the modular grid 4 and carries out, and structural element, wall size, building portion product also all use modular grid 4 to position, a basic module grid M=600mm (seeing grid among Fig. 1).All sizes can be measured with basic module M.Adopt the modular coordination principle that member and connected node are carried out standardized designs simultaneously, can satisfy portion's product batch production and produce desired modular coordination, size try one's best standard and unified condition, to realize suitability for industrialized production.
The basic specification of twin columns unit 1 can have 3 kinds, divides according to girder steel 6 length, as shown in Figure 2, can be respectively 3M, 2M, 1M by the modulus definition.
For strengthening the rigidity of nodes domains, 6 on steel column 5 and girder steel are established the floor 9,10 of putting more energy into.See Fig. 3-5, in a twin columns unit 1, on the steel column 5 (being that about in the of 16 both sides for the steel column web) be provided with level to first, second floor 9 of putting more energy into, this first, second put more energy into floor 9 should be concordant with the girder steel edge of a wing 19, first, second 9 of floor of putting more energy into is established vertically and to be aimed at concordant to the 3rd floor 10, the three floor 10 of putting more energy into of putting more energy into steel beam web plate 20.First, second, third weld seam of putting more energy into 9,10 of floors is a fillet weld 15.First, second, third floor 9,10 of putting more energy into docks welding with girder steel 6.Two steel columns 5 in twin columns unit 1 and girder steel 6 factory by put more energy into floor 9,10 and with butt weld 17 welding good after, transport to the scene as a complete member.
At the construction field (site), twin columns unit 1 and Vierendeel girder 2 connects and comprises the weak direction of principal axis (direction that second moment of area less) parallel with Vierendeel girder 2, and perpendicular to the strong direction of principal axis (direction that second moment of area is bigger) of Vierendeel girder 2.On weak direction of principal axis, referring to Fig. 4, when Vierendeel girder 2 is connected with twin columns unit 1, the web 21 of Vierendeel girder 2 and the 3rd of steel column 5 floor 10 of putting more energy into is connected by high-strength bolt 12 and gusset plate 11, this is to be articulated and connected, and is very convenient.At the frame stiffness of this direction, provide by twin columns unit 1.On strong direction of principal axis, referring to Fig. 5, when promptly Vierendeel girder 2 is connected in the position on the steel column edge of a wing 18 with twin columns unit 1, weld a block plate 13 in the end of Vierendeel girder 2, be connected with the steel column edge of a wing 18 with high-strength bolt 14.This is semi-rigid connection, and certain rigidity is arranged.Can remedy twin columns unit 1 in the more weak problem of this direction rigidity.
The lateral resistant member 3 of twin columns unit 1 has two kinds of ways, and a kind of is to embed buckling-restrained steel plate shear force wall 7 (being applicable to 5 layers and above housing construction) in the middle of twin columns unit 1, sees Fig. 6; Another kind is to be provided with to support 8 in the middle of twin columns, supports 8 and can make (being applicable to 2～4 layers housing construction) with angle steel or square steel pipe, sees Fig. 7.Can make twin columns unit 1 become the bigger structural element of rigidity like this, for structure provides anti-side rigidity.
Steel column is connected employing overall height strength bolt and connects with the splicing of steel column.
For guaranteeing the globality of structure, floor adopts the reinforced concrete cast-in-situ floor.
The external and internal wall of the queen post steel structure of housing that the utility model relates to adopts Autoclaved aerated concrete slabs.
