Abstract

The utility model relates to a rivet, particularly a blind rivet used for steel moulding plates in construction. The utility model is composed of a mushroom-shaped rivet head and a rivet rod. A ring-shaped groove is arranged under the rivet head. When the utility model is in use, the rivet rod is pressed into the hole of a steel moulding plate after aimed at the hole of the steel moulding plate, the ring-shaped groove of the rivet is embedded in the hole of the steel moulding plate, and the goal of the hole pluging can be achieved. The utility model takes effect only by being pressed once, and has the advantages of time saving, labor saving, convenience, simple operation, and low cost. The hole plugging on the steel plate products needs no welding with the help of the utility model.

Description

Blind rivet

The utility model relates to a kind of rivet, particularly relates to a kind of Blind rivet of construction(al)steel template.It is made up of die and rivet rod.

During the building structure cast concrete, common use Sheet Steel Form formwork, to the pin screw bolt reinforcing, need like this on Sheet Steel Form, to hole, when template is had enough to meet the need when using next time, the hole majority of former brill can not use, on stifled, will spillage when cast concrete, both influenced concrete intensity, surface finishment is wasted the concrete mortar again.Past is generally used the welding method plug-hole, and is not only time-consuming bothersome, and welding deformation takes place easily, makes template lift up song, and cost is also high.

The purpose of this utility model provides a kind of Blind rivet, saves time and saves trouble, and is simple and convenient, one by must, with low cost, produce in batches easily.

Technical solution of the present utility model is: Blind rivet is made up of die 1 and

rivet rod

2,1 one-tenth mushroom-like of die, one annular groove 3 is arranged below the die 1, rivet rod 2 is the little down big hollow cylinder of, during use, rivet rod 2 is aimed at the Sheet Steel Form hole, be pressed into, make rivet annular recess 3 just in time among the embedded template hole, reach the purpose of plug-hole.

The utility model has following advantage compared to existing technology: use Blind rivet to save time and save trouble, simple and convenient, one by must, with low cost, particularly solved the problem that plug-hole need not weld on the steel plate goods.

The description of the drawings is as follows:

Fig. 1 is the front view of the utility model Blind rivet.

Fig. 2 is the plan view of the utility model Blind rivet.

Fig. 3 be the utility model Blind rivet along A-A to sectional drawing.

Fig. 4 is the generalized section in the Blind rivet embedded template hole.

Embodiment:

Blind rivet is made up of die 1 and rivet rod 2.Die 1 is mushroom-like, an annular groove 3 is arranged below the die 1, and rivet rod 2 big hollow cylinder for little down, during use, rivet rod 2 is aimed at the Sheet Steel Form holes, is pressed into, and makes rivet annular recess 3 just in time among the embedded template hole, reaches the purpose of plug-hole.The rubber that Blind rivet uses generally that toughness is strong, good springiness, specific elongation height have certain degree of hardness can satisfy usage requirement as other material and also can select for use as raw material.

Claims

1, a kind of Blind rivet is made up of die and rivet rod, and die is mushroom-like, and it is characterized in that has an annular groove 3 below the die 1, and rivet rod 2 is the little down big hollow cylinder of.
