The specific embodiment

The full component building thing of the utility model outsourcing cold formed steel is meant the full component building system that is formed by clod wash square tube concrete combination column, outer lipped channel compound beam and cold forming profiled sheet concrete composite floor system and the set of cold forming profiled sheet combined wall.

Wherein, cold forming square tube concrete column be in empty steel pipe placing of concrete, the two forms integral body and the bending component of collaborative work, has higher capacity, good deformability and energy dissipation capacity.Under the axial pressure effect, the pipe inner concrete is subjected to the lateral restraint of outer steel pipe and forms the stress state that core concrete is in three dimension stress, not only improved compressive strength, but also increased plastic deformation ability, core concrete provides the skeleton supporting role simultaneously, avoids outside steel pipe that cripling takes place in pressurized process.

Outer lipped channel compound beam is steel plate to be welded into or clod wash becomes as shown in Figure 5 the cross section as the beam rib, and disturbing concrete in the flank in cross section and the edge of a wing, top forms that steel---the member of concrete T type compound section is to bear external load jointly.In civil engineering, this shape for hat cross section steel-concrete combination beam, because inner fill concrete, make member both increase rigidity of section, prevent that again steel fine strain of millet from doing the time spent separately, be easy to generate crippling because of the web height approaches, reduce depth of beam with increase house headroom, but and the construction volume accelerating construction progress of minimizing template.In a word owing to made full use of two kinds of different stress performances of material of concrete and steel, thereby have that bearing capacity height, ductility are good, comprehensive economic index is than advantages such as height.

As shown in Figure 4, according to the building demand, on inner surface around the square tube 14, all be welded with stiffener 16 or rivet 17, wherein, the position of stiffener 16 or rivet 17 and quantity are according to calculating.

As shown in Figure 1, when the construction construction of the full component building thing of outsourcing cold formed steel, at first the two ends of hat shape steel 15 are passed square tube 14 and fixing with it, the axis of the stiffener 16 in the square tube 14 is parallel with the axis of hat shape steel 15, again T-steel 3 is laid on the surface of hat shape steel 15, the two ends and the hat shape steel 15 of T-steel 3 are welded together, profiled sheet 1 is installed on the surface of T-steel 3 and and connects by shear key.Like this, rectangular steel pipe 14, hat shape steel 15, T-steel 3 and profiled sheet 1 form unified integral body, and according to the calculation requirement of routine, behind floor and the suitable arrangement of reinforcement of shape for hat beam, are that a standard block carries out concrete cast with every layer.After the concrete final set, then according to specific requirement, cold forming profiled sheet combined wall and this standard unit are assembled, combined wall is by being connected with built-in fitting in the floor, and promptly T-steel 3 is connected with built-in fitting, simultaneously T-steel 3 double wall beam and the keel done.

Cold forming profiled sheet concrete composite floor system and cold forming profiled sheet combined wall are to utilize the profiled sheet combining structure as flooring with go along with sb. to guard him system.As shown in Figure 2, this combined system is made up of remain silent profiled sheet 1 (SBS-605600) and T-steel 2 and steel concrete.The profiled sheet 1 of remaining silent is fastened by connecting key 2 with T-steel 3 members and is connected together, after disposing certain reinforcing bar according to demand, with the profiled sheet 1 double template of doing of remaining silent, fluid concrete thereon, the adhesion stress between profiled sheet 1 and the concrete and the shearing force of connecting key 2 make it become an organic whole by remaining silent.Profiled sheet 1 and the T-steel 3 of remaining silent forms the template and the supporting platform of whole floor slab construction, and by conventional construction measure, makes its double primary structure member of doing.The profiled sheet 1 double steel bar stress of doing of remaining silent, the T-steel 3 double secondary beams of doing, wherein T-steel 3 also can substitute with shaped steel 4 as shown in Figure 6.When this system is used as exterior wall, as shown in Figure 3, at first constitute the main skeleton of whole keel wall board with the shaped steel 4 and the profiled sheet 1 of remaining silent, interior wall 5 can adopt materials such as gypsum plank according to demand, and interior wall 5 materials (gypsum plank etc.) are connected on the shaped steel 4 by self threading pin; At 5 of interior walls and 4 air layers 6 that form sealing of shaped steel, and cooperate heat preserving and insulating material 7 to unite the effect of playing the thermal insulation sound insulation, heat preserving and insulating material 7 generally is filled in the inboard of shaped steel 4 or adopts polyphenyl class material to be sprayed on the inboard of shaped steel 4; Exterior wall 8 adds external wall decorative material 13 etc. by touching ash 12 behind connector 10 extension stone materials or the use dipy model net 11 generally as required.In exterior wall, the double keel of doing wall beam and interior facing connection of T-steel or shaped steel are by regulating the thickness of heat preserving and insulating material, can satisfy the requirement of the varying environment of different regions, and this system convenient and quick construction, because the multiple action of T-steel or shaped steel 4 can be saved certain construction costs.Profiled sheet-concrete combined floor is a kind of novel floor slab structure form, profiled sheet and concrete combination, steel plate tension and the measuring body advantage of concrete have been brought into play in effect, pair cross-section rigidity also has certain contribution, and have that concrete amount reduces, construction weight alleviates, saves a large amount of templates, easy construction, construction speed are fast, be convenient to advantage such as pipe laying.

The full component building thing of this outsourcing cold formed steel advantages such as advanced person, economical rationality, fabrication and installation are convenient, speed of application is fast that possess skills, particularly main following points: 1. the connection of square tube and shape for hat fine strain of millet is can be according to the form of node different takes different connected modes, generally uses the mode of reinforcing bar telepathy or holdfast plate to connect.This method construct is simple, easy construction.Especially do not have the outer shroud structure, can not bring the trouble of concealed nodes, have the building of making advantage attractive in appearance to building; 2. the shape for hat beam links together profiled sheet and T-steel with being connected at first of floor by shear key, and T-steel links together by spotweld and shape for hat fine strain of millet, thereby forms an integral body.Before the concrete final set, T-steel provides lateral support to shape for hat fine strain of millet, prevents unstability outside the plane of hat shape steel; After the concrete final set, shear key will increase the adhesion stress of concrete and profiled sheet, make it to become a more effectively integral body; 3. wall body structure is by being connected with built-in fitting in the floor, and promptly T-steel is connected with built-in fitting, simple structure, and double wall beam and the keel done of T-steel can reduce cost simultaneously; 4. whole building system is not used template substantially in construction, only adopt a small amount of supporting when span is big, can accelerate speed of application thus, reduce construction cost.
