Description
Technical field
It the utility model is related to rivet technology field, and in particular to a kind of fiber cement external wall panel is connected with keel with breaking
Bar internally-arranged type exterior wall rivet.
Background technology
Rivet is to be used to connect two band through holes, and there is the part of cap one end（Or component）Spike part.In riveting, profit
The part being riveted with self-deformation or interference connection.Rivet species is a lot, and informal.Conventional has R snap rivetings nail, wind
Fan rivet, self-plugging rivet（Drive Rivet）, tree-like rivet, cup head, tack, semitubular rivet, solid rivet, sunk head rivet,
Self-plugging rivet, tubular rivet, these are typically to be riveted part using self-deformation connection.Generally less than 8 millimeters of use cold riveting, greatly
Rivet hot is used in this size.But also there is exception, such as the nameplate on some locksets, it is exactly the interference using rivet and lock body opening
Amount riveting.
The connection rivet of existing fiber cement board exterior wall connection keel is usually using common self-plugging rivet, due to core pulling riveting
Nail structure problem itself, the shaft of rivet is hollow state after core pulling axle pulls out, and the problem of shearing force is low be present, due to exterior wall after use
The reasons such as plate self gravitation, the time grown after easily cause the shaft of rivet because the shearing force that gravity is formed causes the shaft of rivet to be broken,
And cause exterior wall to drop, certain potential safety hazard be present.
Utility model content
The purpose of this utility model is to provide a kind of fiber cement external wall panel and is connected with keel with breaking outside bar internally-arranged type
Wall rivet, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of fiber cement external wall panel is connected with keel with breaking bar internally-arranged type exterior wall rivet, including rivet shell, rivet shell
Bottom is fixedly connected with manufactured head, and rivet shell centre offers rivet housing hole, core pulling axle, core pulling are provided with the rivet shell
Shaft length is more than rivet shell length, and core pulling axle top is fixedly connected with spindle nose；Evagination bayonet socket, evagination are provided with the core pulling axle
Bayonet socket diameter is more than rivet housing hole diameter, and evagination bayonet socket diameter is less than manufactured head diameter；Core pulling axle below outer tappet mouth
Fracture is provided with side wall.
It is as further program of the utility model：The spindle nose is fixedly connected by cold pier technique with core pulling axle.
As the utility model, further scheme is：The evagination bayonet socket is made up of cold heading technique.
As the utility model, further scheme is：The evagination bayonet shape is described to be cylindric or circular
Fracture is shaped as the annular groove shape of depression.
As the utility model, further scheme is：The rivet shell and core pulling axle are that metal material is made.
The beneficial effects of the utility model are：
1. easily fill, be handy；
2. strengthen the anti-shearing force after rivet use；
3. increase the stretching resistance after rivet use.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1-Fig. 5, in the utility model embodiment, a kind of fiber cement external wall panel is connected with keel with breaking bar
Internally-arranged type exterior wall rivet, including rivet shell 11, the bottom of rivet shell 11 are fixedly connected with manufactured head 12, and the centre of rivet shell 11 opens up
There is rivet housing hole 13, core pulling axle 4 is provided with the rivet shell 11, the length of core pulling axle 4 is more than the length of rivet shell 11, core pulling axle 4
Top is fixedly connected with spindle nose 1；Evagination bayonet socket 2 is provided with the core pulling axle 4, the diameter of evagination bayonet socket 2 is more than rivet housing hole 13
Diameter, and the diameter of evagination bayonet socket 2 is less than the diameter of manufactured head 12；Fracture is provided with the side wall of core pulling axle 4 below outer tappet mouth 2
Portion 3, conventionally, as fracture 3, on the top of core pulling axle 4, core pulling axle 4 is after core pulling, the spindle nose on the top of core pulling axle 4
1 fracture is stayed in rivet shell 11, while spindle nose 1 also can be fully wrapped around by rivet shell 11, so that the inside of rivet shell 11 is in hollow
Shape, as shown in Fig. 2 the problem of shearing force is low be present, due to reasons such as Side fascia self gravitations after use, the time has been grown rear easy
The shearing force for causing the shaft of rivet to be formed due to gravity causes the shaft of rivet to be broken, and causes exterior wall to drop, and certain potential safety hazard be present；
In the utility model, fracture 3 is arranged on the core pulling axle 4 of the lower section of evagination bayonet socket 2, after the core pulling of core pulling axle 4, top
Core pulling axle 4 can be broken inside rivet shell 11, so as to be filled to rivet inside, make what fiber cement board exterior wall was connected with keel
Shaft of rivet shear ability strengthens, so as to solve because the shearing force that the reasons such as Side fascia self gravitation are formed causes the shaft of rivet to be broken
Situation.
Fracture 3 is located at length on the core pulling axle 4 of the lower section of evagination bayonet socket 2 and determined by use environment.
The spindle nose 1 is fixedly connected by cold pier technique with core pulling axle 4.
The evagination bayonet socket 2 is made up of cold heading technique.
The evagination bayonet socket 2 be shaped as it is cylindric or circular, the fracture 3 be shaped as depression annular groove shape.
The rivet shell 11 and core pulling axle 4 are that metal material is made.
The position of fracture 3 on the core pulling axle determines by exterior wall thickness and keel thickness, the post-rift length of mandrel 4
Generally exterior wall thickness and keel thickness sum, but might be less that exterior wall thickness and keel thickness sum.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
