Abstract
The utility model relates to a kind of band tooth gaskets, including the shim body being adapted with nut, it is arranged on shim body surface, multiple metal tines provided around it, the corresponding another surface of shim body is smooth, smooth surface is contacted with nut, and the surface with metal tines is contacted with the wooden component of connection.Compared with prior art, the utility model is equipped with pointed tooth in gasket side, and spacer for bolt pointed tooth is pressed into timber in nut rundown process, by pointed tooth to a kind of constraint of screw hole periphery wood formation, enhance the anti-crack ability of screw hole periphery timber, promotes joint behavior, prevent component surface premature rupture.
Description
Technical field
The utility model relates to belong to civil construction project field, more particularly, to a kind of band tooth gasket.
Background technique
Beam column bolt joint is a kind of common wooden component connecting node in heavy timber construction, usually by the connected wooden structure
Part, interior steel plate and the bolt filled out are constituted.Timber near the wooden component bolt hole is due to will receive damage, material phase in prebored hole
Than can decrease in other region timber.
In the prior art, the circular gasket more bigger than the diameter of bolt is generally used, is only capable of dispersion nut to connected piece
Pressure and the surface of connected piece is protected not abraded by bolt, the wood performance around screw hole is not promoted.
Utility model content
The purpose of this utility model is exactly to overcome the problems of the above-mentioned prior art and providing one kind prevents component
The band tooth gasket of surface premature rupture.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of band tooth gasket is arranged on shim body surface, sets around it including the shim body being adapted with nut
The multiple metal tines set, the corresponding another surface of shim body is smooth,
Smooth surface is contacted with nut, and the surface with metal tines is contacted with the wooden component of connection.
The metal tines are conical structure, are evenly arranged on a side surface of shim body.
The both ends that bolt is set in tooth gasket, with metal tines one facing towards the wooden component, covered on another side
Equipped with nut.
The tip of the metal tines is embedded into the wooden component.
Steel plate is embedded in the wood component.
The bolt pass through embedded in the wooden component in fill out steel plate.
Compared with prior art, the utility model is equipped with pointed tooth in gasket side, by bolting pad in nut rundown process
Piece pointed tooth is pressed into timber, by pointed tooth to a kind of constraint of screw hole periphery wood formation, enhances the anti-crack ability of screw hole periphery timber,
Joint behavior is promoted, component surface premature rupture is prevented.

Specific embodiment
The utility model is described in detail combined with specific embodiments below.Following embodiment will be helpful to this field
Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made.
These are all within the protection scope of the present invention.
Embodiment
A kind of band tooth gasket 1, structure is as shown in Figure 1, include the shim body 1-1 being adapted with nut, setting is being padded
The surface piece ontology 1-1, multiple metal tines 1-2 provided around it, metal tines 1-2 are conical structure, are evenly arranged on pad
On a side surface of piece ontology 1-1, the corresponding another surface shim body 1-1 is smooth, and smooth surface is contacted with nut 2, band
The surface of metal tines is contacted with the wooden component of connection.
The structure of the utility model when in use is as in Figure 2-4, applies and fills out steel plate bolt joint in timber structure beam column
In, the node include the interconnected first wooden component 3 and the second wooden component 4 and it is interior fill out steel plate 6, inside fill out steel plate 6 embedded in the
In the two wooden components 3 and the first wooden component 4 is passed through for connecting two wooden components.In addition, node further include: bolt 5, nut 2, with
Band tooth gasket 1 is bolted the first wooden component 4 of the wooden component 3, second with interior and fills out steel plate 6.During tightening nut,
Pointed tooth with tooth gasket is embedded in the wooden component, constrains screw hole periphery timber.
The both ends of bolt 5 are set in tooth gasket 1, one with metal tines is arranged facing towards the wooden component on another side
There is nut 2.Bolt pass through embedded in the wooden component in fill out steel plate.The tip of metal tines is embedded into the wooden component.It is twisted in nut
Spacer for bolt pointed tooth is pressed into timber during tight, by pointed tooth to a kind of constraint of screw hole periphery wood formation, enhances screw hole week
The anti-crack ability of side timber promotes joint behavior, prevents component surface premature rupture.
It can understand the above description of the embodiments is intended to facilitate those skilled in the art and use practical
It is novel.Person skilled in the art obviously easily can make various modifications to these embodiments, and illustrating herein
General Principle be applied in other embodiments without having to go through creative labor.Therefore, the utility model is not limited to above-mentioned
Embodiment, those skilled in the art's announcement according to the present utility model, do not depart from improvement that the utility model scope is made and
Modification should be all within the protection scope of the utility model.
