Abstract

The utility model relates to a clamp nut, and relates to commonly used construction pieces. The utility model is assembled by two independent and separated nuts which are mutually jointed into an integral nut. A ferrule is sheathed in and tightly fixed to a groove formed in the jointed back nut, and the head of the ferrule is a conical bolt which can be screwed in along the opening which is formed after the nuts are jointed. Convex teeth are evenly arranged on the circumference of the jointed nut, and the jointing surface of the two nuts is correspondingly provided with a convex and a concave positioning pins. The terminal part of the conical bolt is a construction piece provided with a-shaped, b-shaped, c-shaped, d-shaped, e-shaped, f-shaped means, etc. Because the groove fixed by the ferrule is positioned near the terminal part of the nut, when the conical bolt is screwed in from the opening of the nut, the top parts of the two nuts are pushed out to form a V shape. The convex teeth arranged on the nuts can fully expand and contact a structural layer of concrete, which leads to everincreasing friction with the structural layer, and the structural layer is compressed and extruded; consequently, the effects of fastening and pull-resistance are achieved.

Description

A kind of tightening nut

Technical field

The utility model relates to construction part commonly used, particularly a kind of tightening nut.

Background technique

Existing common setscrew is made up of stud bolt, metallic sheath and nut, when stud bolt screwed in nut, the connection band on the nut burst apart, thereby the double wedge on the nut is contacted with concrete, but skidding often appears in stud bolt in the screw-in process, influence construction operation, and bolt end portion is a screw, is exposed to surface of wall more, fail directly to be used with various members, need required member is welded on the bolt end, promptly labor intensive increases construction cost again.

Summary of the invention

The utility model for address the above problem provide a kind of tensility better, be difficult for skidding the tightening nut that can directly be used in combination with multiple accessory.

The utility model is bonded with each other by the nut of two independent separate and forms a complete nut, metal ferrules is inserted in and is anchored on and engages in the formed groove of back nut, head is the taper bolt of taper, can screw in along formed opening after the nut engages, connect on the circumference of back nut and be distributed with double wedge, the corresponding locating stud that is distributed with convex and spill on the mating face of two nuts, the last portion of taper bolt is a workpiece for building;

Above-mentioned described workpiece for building includes the taper bolt of shapes such as member a shape, b shape, c shape, d shape, e shape, f shape.

Adopt technique scheme, by metal ferrules together with the nut engages of two independent separate, thereby form a complete nut, because the fixing groove of metal ferrules is positioned near the last portion of nut, when taper bolt is screwed in by the opening of nut and screws in certain depth, the top of two nuts is strutted, form the V shape, and the double wedge that distributes on the nut can fully open and contact with construction layer in the concrete, the friction of itself and construction layer is constantly increased, and crowded, extrusion structure layer, thereby reach effect fastening, tension.

The last portion of taper bolt is a workpiece for building, and multiple shapes such as a, b, c, d, e, f are arranged respectively, and it can select suitable taper bolt neatly according to the needs of construction, and itself and various construction member are used, and reaches best assembled state.

Embodiment

As Fig. 1, shown in Figure 2: the semi-circular nut (1 of two independent separate that are made of metal, 1 '), by metal ferrules 4 with above-mentioned nut (1,1 ') be bonded with each other after, form a complete round nut, and metal ferrules 4 is fixed near the groove 5 of round nut end portion, be distributed with stair-stepping double wedge 2 on the circumference of round nut after engaging, and semicircle type nut (1,1 ') be symmetrically distributed with the locating stud 3 of convex and spill on the mating face that is bonded with each other, taper bolt 6 is a taper by a top, end portion is that the single piece of workpiece 7 for building is formed, be distributed with screw thread on the taper at top, pass through external force, taper bolt can be along semicircle nut (1,1 ') the formed opening in back that is bonded with each other screws in, because semi-circular nut (1,1 ') inwall is distributed with internal thread, can cooperatively interact with the outside thread of taper bolt combines closely the taper bolts and nuts, and the workpiece for building 7 of taper bolt 6 last portions can be a suspender, barb member, fastening piece etc.;

Above-mentioned described nut can be made or other materials by working of plastics, and its shape can have multiple, as circle, polygonal etc.

Described locating stud 3 can be distributed on the nut surface of contact of (1,1 '), and is ∽ shape joint.

During use, with semicircle nut (1,1 ') fit together mutually by locating stud 3, metal ferrules 4 is inserted in the groove 5 on the nut, again this nut is put in the sizeable concrete hole, and choose workpiece 7 for building, the taper bolt 6 that will have a workpiece for building is by the external force nut (1 of outwarding winding, 1 ') opening that forms, in the process of screw-in, two lobe blades on the nut can expand outwardly, and nut (1,1 ') double wedge on will constantly push and fully contact with the construction layer of concrete hole wall, thereby the increase friction reaches fastening, the purpose of tension.

As shown in Figure 3, present embodiment adopts the taper bolt 6 of band member a shape and the taper bolt 6 of band d shape, by taper bolt 6 being anchored in the nut as above-mentioned said embodiment, be hung with drag-line on the bolt 6, drag-line can hang ceiling board, shelf, keel, swing pipe etc. fixing.

As shown in Figure 4, present embodiment adopts four taper bolts 6 of band member c shape, with building components equalizing suspension systems such as airduct, fixing, other mode of executions such as Fig. 1,2 roughly the same.

As shown in Figure 5, present embodiment adopts the taper bolt of band member b shape, be used for fixing the copper post, its mode of execution: at first the copper post is positioned on the concrete structure layer, at copper post periphery fixed copper column base pad, owing to have four through holes on the seat cushion, the taper bolt of band member b shape can insert in the through hole, and fully contacts with concrete, and the copper post is fixed on the concrete, other mode of executions such as Fig. 1, Fig. 2 mutually roughly the same, this mode of execution compares with existing mounting type that it is easy to use, simple, quick.

As shown in Figure 6, embodiment and Fig. 5 mutually roughly the same, difference is to adopt the taper bolt 6 of band member e shape, and bolt 6 is anchored on the circular copper column base pad.

As shown in Figure 7, embodiment and Fig. 5 mutually roughly the same, difference is to adopt the taper bolts 6 of three band member f shapes, and bolt 6 is anchored on the triangle copper column base pad.
