Abstract
The utility model relates to a fastener for construction. The utility model is characterized in that a screw bolt (1) penetrates through the bolt hole of a fixed member (5), the screw bolt (1) is sheathed with an arc-shaped washer (2) and is tightened with a nut (3); besides, when the arc-shaped washer is not used, the screw bolt (1) is directly sheathed with an arc-shaped nut (4) and is tightened with the head of the screw bolt, and the purpose of tightening the fixed member is realized. The arc surface of the arc-shaped washer or the arc-shaped nut of the utility model has a larger contact area with the arc surface of the fixed member; the utility model has the advantages that stress distribution is uniform, and the utility model has a favorable tightening effect.
Description
The utility model relates to fastening piece for building.
Existing building mostly is the plane with packing ring or its stress surface of nut of fastening piece, as the component surface that is fixed is when being circular arc, then thisly be connected with following shortcoming: packing ring or the nut member area of contact that is fixed is little, pressure distribution is inhomogeneous, cause fastening effect relatively poor, be easy to generate loosening during member stress.
It is relatively poor with the fastening effect of the packing ring of fastening piece or nut that the purpose of this utility model is to overcome above-mentioned existing building, provides a kind of fastening effect comparatively desirable fastening piece for building.
The utility model is to finish like this: fastening piece for building is made up of bolt (1), curved washer (2), nut (3) and arc nut (4).Design a kind of packing ring (2) of single face arc, its cambered surface radian can be decided according to the surperficial radian of building working standard member, when stressed its cambered surface of this curved washer contacts with the member that is fixed, because its cambered surface is now bigger with the area of contact of the solid member of quilt with the packing ring plane, identical down in other condition, increased friction factor, thereby made pressure distribution more even, fastening effect is more satisfactory.Also can be when not using packing ring, the stress surface of nut is designed to arc (4), play comparatively ideal effect equally.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural drawing of the present utility model.
Fig. 2,3 is user mode figure of the present utility model.
Bolt (1) passes the member that is fixed (5) keyhole, puts curved washer (2), goes up jack panel (3) again, and curved washer and the circular arc member area of contact that is fixed is bigger, and pressure distribution is even, reaches more satisfactory fastening effect.When using arc nut (4), then put the arc nut, the head that tights a bolt can reach desirable fastening effect equally.
General now less with the area of contact of the solid member of quilt with the packing ring plane, cause the pressure distribution inequality, fastening effect is relatively poor.
Claims (3)
1. a fastening piece for building comprises bolt (1), packing ring (2), nut (3), nut (4), it is characterized in that packing ring (2) or nut (3) are the single face arc.
2. according to the described fastening piece for building of claim 1, it is characterized in that gasket design is the single face arc, its cambered surface radian can be decided according to the surperficial radian of building working standard member, and its cambered surface contacts with the arc surface of fixture.
3. according to the described fastening piece for building of claim 1, when it is characterized in that not using packing ring, the nut of use is designed to the single face arc, and its arc contacts with the arc surface of the member that is fixed.
