Description

Light steel house superstructure syndeton
Technical field
The utility model relates to a kind of building superstructure syndeton, is specifically related to a kind of light steel house superstructure syndeton.
Background technology
Light steel house is exactly a structural skeleton of setting up the house with the thin-walled steel, and this structure has that wall is thin, consumable quantity is low, from heavy and light, rapid, advantage that anti-seismic performance is good easy for installation.
Traditional way be with C shaped steel as stock, form structural element such as post, body of wall, beam then with C shaped steel, further build the structural skeleton in whole house.But C shaped steel self is thin-wall open section steel, the local buckling that therefore under stressed effect, is easy to take place thin plate; On the other hand, the web of C shaped steel is a whole plate, and consumable quantity is big, and cold and hot bridge phenomenon is serious, need outside skeleton, do outside one deck being incubated, and construction is trouble very.
These problems between C shaped steel; Developed in recent years and added the web connector with light steel quarter bend and form jack truss and come replaced C shaped steel as stock; And then, further build the structural skeleton in whole house with structural element such as this jack truss composition pillar, body of wall, beams.This jack truss has overcome the problem of C shaped steel opening thin, makees chord member with the quarter bend of remaining silent, thereby has improved the thin plate local stability greatly; In addition, the compartment of terrain is provided with the web connector between the chord member, has reduced cold and hot bridge phenomenon greatly.
The traditional method that the light steel of this jack truss house superstructure connects is: U type groove is set on the body of wall top one, on U type groove, places the upper chord of floor beam then, on the upper chord of floor beam, place the bottom U type groove of upper strata body of wall again.This way makes that floor is separated completely up and down, has seriously undermined structural stability, and the load of upper strata body of wall all passes to lower floor's body of wall through the top chord member of floor beam, is easy to like this lateral deflection of floor beam upper chord.
Therefore in later development, adopted in the middle of body of wall a quarter bend is set, the floor beam upper chord rides on this root quarter bend, a quarter bend is set on the floor beam upper chord then again it is pushed down.This way has solved the problem that floor that U type groove superstructure connects is cut off unstable and the easy lateral deflection of floor beam upper chord; But the load that transmits floor beam with single quarter bend is also undesirable to the way on the wall column, and when spacing big when load or wall column was big, single quarter bend just was difficult to carry; In addition, floor beam adopts upper chord to be connected with body of wall, and this can make all floor beam shearings bear by upper chord, and the outer of first connector is located upper chord and born relatively large moment of flexure at the floor beam two ends, makes upper chord flexing herein easily.
Summary of the invention
In view of this, the utility model provides a kind of light steel house superstructure syndeton, and this superstructure connection integrity is strong, and structural stability is strong, and coupling stiffness is big, and power transmission is effective, and the chord member of floor beam can not occur by phenomenons such as lateral deflections.
The light steel house superstructure syndeton of the utility model; Said light steel house comprises light steel superstructure and light steel wall, and said light steel wall comprises the crossbeam of horizontally set, and said light steel superstructure comprises floor beam; Said crossbeam and floor beam are trussed construction; Said trussed construction comprises chord member and web connector, is arranged in parallel between the said chord member and passes through the web connector to connect, and said floor beam and light steel wall intersect; The upper chord of said floor beam rides on the upper chord of crossbeam and with it and is fixedly connected, and the lower chord of floor beam rides on the lower chord of crossbeam and with it and is fixedly connected.
Further, the upper chord of said floor beam is fixedly connected through the angle steel connector with the upper chord of crossbeam, and the lower chord of said floor beam is fixedly connected through the angle steel connector with the lower chord of crossbeam;
Further, said crossbeam and floor beam are the sheet shape trussed construction that two chord members are formed;
Further, the cross section of said chord member is rectangle, C type or hat section;
Further, the material of said chord member and web connector is thin-walled steel, aluminium alloys or glass fiber reinforced plastic;
Further, said light steel superstructure also comprises floor plate, and said floor plate is laid on the floor beam.
The beneficial effect of the utility model is: the superstructure connection integrity of the utility model is strong; Structural stability is strong, and the floor that has solved traditional U type groove superstructure connection is well cut off problem of unstable, and coupling stiffness is big; Power transmission is effective; Solved single quarter bend superstructure and connected the low problem of bearing capacity, simultaneously, the chord member of floor beam can not occur by phenomenons such as lateral deflections; The superstructure syndeton of the utility model is simple, and easy construction can be widely used in the superstructure connection in light steel house.
