The utility model discloses the floor have simple structure, line arrangment nimble, need not the welding, make things convenient for advantage such as prefabricated construction.
Description
Technical field
Utility model relates to floor of steel structure, particularly a kind of cold bending thin wall light section steel structure truss floor.
Background technology
Be applied to the floor of steel structure of Light-weight Steel Structures, substantially adopt two kinds of forms traditionally:
A kind of for lay structural slab as oriented structure chipboard on real abdomen cold-formed thin-walled C steel beam, the dalle of upper berth other types, the floor of this pattern in use, its span scope restricted (being generally no more than 6m), and easily produce vibration and soundproof effect is poor.
The another kind of girder steel form for adopting shaped steel to be formed by connecting by welding or bolt, and then lay oriented structure chipboard etc.But it operates comparatively complicated in welding or screwing process and oriented structure chipboard is perishable.
In addition, when arranging pipeline, the floor of steel structure of conventional version all needs to punch, and causes bearing capacity to reduce.
Utility model content
The shortcomings such as the purpose of this utility model designs a kind of cold bending thin wall light section steel structure truss floor, solves traditional light section steel structure sound isolation of floor weak effect, and floor trembles, and installation process is complicated.
For achieving the above object, the technical solution of the utility model is:
A kind of cold bending thin wall light section steel structure truss floor, it comprises, steel truss, and it is formed by connecting by self-drilling self-tapping nail primarily of upper and lower chord member and web member; Wherein, upper and lower chord member be [type Steel Thin-Wall, web member is C type Steel Thin-Wall; Top angle, is arranged on the angle end of described steel truss, is connected with steel truss by self-drilling self-tapping nail; Gripper shoe, is covered on described steel truss, gripper shoe is established pea gravel concreten layer.
Preferably, described C, [wall thickness of type Steel Thin-Wall is 1.0mm ~ 2.0mm, and zinc-plated or zinc layers of aluminizing is established on its surface.
Preferably, described steel truss depth of truss is no more than 300mm, and spacing is not more than 600mm, and span is not more than 8m.
Preferably, described top angle cross section is L50 × 50 × (3 ~ 5) mm, and elongated four the angle ends be arranged on perpendicular to steel truss carry out bound edge process, is connected with steel truss by self-drilling self-tapping nail;
Preferably, described gripper shoe thickness is not less than 12mm.
Preferably, described gripper shoe is oriented structure chipboard (OrientedStrandBoard, OSB).
Preferably, described coagulate layer thickness is 30 ~ 40mm.
Preferably, the built-in steel fabric sheet of described concrete.
Preferably, described self-drilling self-tapping nail adopts ST4.2, and edges of boards pitch of nails is not more than 150mm, and in plate, pitch of nails is not more than 300mm, and self-drilling self-tapping nail at least exposes three circle screw threads after penetrating steel work.
The utility model adopts cold bending thin wall C, [steel truss of shaped steel composition, carries out bound edge process by the elongated angle steel be arranged on perpendicular to truss four angle ends between truss.Concrete cast-in-situ, on gripper shoe, increases integral rigidity and stability in plane.
Compared with prior art, basis is practical has the following advantages:
1, easy construction, has directly pre-installed in factory.With self-drilling self-tapping nail to thin-walled C, [shaped steel connects, and can complete whole soft steel board simply, fast.
2, save floor space, equipment pipe is placed convenient.Because there are enough spaces this kind of floor inside, so many pipelines can be placed, so both can reduce the space that equipment pipe takies at floor, also can increase the aesthetic property of whole floor.
3, floor span is flexible.Because the utility model can adopt multiple single truss structure to be formed by connecting, according to design needs, span demand can be met by the adjustment thickness of light gauge cold-formed steel shape and the height of single truss structure.
4, intensity is high and soundproof effect good.Owing to placing oriented structure chipboard and concreting on truss, make monoblock floor strength higher, and soundproof effect is also fine.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
See Fig. 1 ~ Fig. 3, a kind of cold bending thin wall light section steel structure truss floor of the present utility model, it comprises, steel truss 1, and it is formed by connecting by self-drilling self-tapping nail 14 primarily of upper and lower chord member 11,12 and web member 13; Wherein, upper and lower chord member 11,12 be [type Steel Thin-Wall, web member 13 is C type Steel Thin-Wall; Top angle 2, is arranged on the angle end of described steel truss 1, is connected with steel truss 1 by self-drilling self-tapping nail 3; Gripper shoe 4, is covered on described steel truss 1, gripper shoe 4 is established layer of concrete 5.
Preferably, described C type, [wall thickness of type Steel Thin-Wall is 1.0mm ~ 2.0mm, and zinc-plated or zinc layers of aluminizing is established on its surface.
Preferably, described steel truss 1 depth of truss is no more than 300mm, and spacing is not more than 600, and span is not more than 8m.
In the present embodiment, described top angle 2 cross section is L50 × 50 × 6, and elongated four the angle ends be arranged on perpendicular to steel truss, carry out bound edge process, is connected with steel truss by self-drilling self-tapping nail;
