Abstract

PURPOSE: A bolt connector is provided to prevent a cover from being easily separated from the bolt connector by forming a guiding inclined surface on the inner surface of a nut housing unit. CONSTITUTION: A bolt connector(100) comprises a cover(170). The cover comprises a nut housing unit(110), a nut(160), and a hanging protrusion(171). A bottom end unit(120) is formed in the bottom end of the nut housing unit. The nut is inserted into the nut housing unit. The hanging protrusion has a shape corresponding with the outer shape of the nut to prevent the nut from being rotated. A guiding inclined surface(150) is formed on the inner surface of the nut housing unit. A concave groove(151) is formed in the bottom end of the guiding inclined surface.

Description

Bolt Connector

The present invention relates to a bolt connector, and more particularly, a bolt connector for allowing a bolt to be fastened by being embedded in concrete with a nut housed therein so that the structure held by the bolt can be installed in concrete. It is about.

In general, concrete has a significant hardness, so it is not easy to install the structure in concrete.

Therefore, conventionally anchor bolts, etc. may be used, which is mainly used to install a structure in concrete by drilling a hole in the concrete and inserting and fixing the nut in the hole and fastening the bolt to the nut.

However, this bolt connection method is very reliable, even if the hole for inserting the threaded anchor is inserted into the concrete, and the anchor is inserted and fixed, the anchor is vulnerable to vibration and is detached when a strong force is applied. Not a way to be.

Therefore, in order to solve the disadvantage that the anchor bolt has a nut accommodating portion is formed in a shape that corresponds to the outer shape of the nut so that the nut is accommodated; A nut coupled to the fastening bolt and coupled to the nut accommodating part; The nut accommodating portion is coupled to the lower end by forming a lower end portion having a space in a shape corresponding to the outer shape of the nut accommodating portion so that the nut accommodating portion is completely inserted and extending upwardly at the lower end with a size smaller than the lower end portion. A cover including an upper end formed therein so that the through hole corresponding to the screw of the nut coupled to the nut accommodating part is in communication with the inside of the lower end; Since the bolt connector is made to be buried in concrete before the concrete is placed in advance, when the curing of the concrete is completed, the nut is firmly fixed in the concrete so as not to be released, thereby stably installing the structure on the nut.

However, the conventional bolt connector has a structure in which a locking projection protruding outwardly is formed at the lower end of the cover in which the nut is accommodated, but the locking jaw corresponding to the cover also protrudes in the inner lower end of the nut housing. Therefore, it is not easy to insert the cover into the nut accommodating part in the state where the nut is accommodated by the locking projection and the locking jaw having the same diameter, and it is also easy to fix the cover by fitting the nut accommodating part that is not loose. Not work

In addition, the conventional bolt connector does not have any means for reinforcing it between the nut housing and the lower end, so that the nut housing and the lower end having different diameters may be vulnerable to bending or towing pressure.

Therefore, the present invention was devised to solve the above problems, and the nut housing portion formed with a lower end portion having a smaller diameter at the bottom, the nut accommodated in the nut receiving portion and the outer shape of the nut to prevent the nut from rotating In the bolt connector made of a cover having a shape and having a locking jaw at the bottom, the inner side of the nut receiving portion is provided with a funnel-shaped inclined surface having a wide diameter of the upper portion and a narrow diameter of the lower portion of the lower portion of the inclined surface The concave groove is formed to be round to provide a bolt coupler characterized in that the locking step of the cover is configured to be caught in the concave groove.

In another aspect, the present invention is to provide a bolt coupler characterized in that the reinforcing nut receiving portion and the lower end that can be weakened by the concave groove by a plurality of reinforcing rods.

As such, the present invention is easy to insert the cover by forming a funnel-shaped inclined surface on the inner surface of the nut receiving portion, and the locking jaw of the cover is coupled to the concave groove of the guide inclined surface simply by pushing the cover. It is a very useful invention that is easy to work, and easy to remove the cover can also reduce the risk of loss of the cover.

2-a combined perspective view of the present invention.
3-a cross-sectional view of the present invention.
4-Reference state of use of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, the bolt connector 100 has a nut housing 110 having a lower diameter portion 120 formed at a lower end thereof, a nut 160 accommodated in the nut receiving portion, and an outer shape of the nut so that the nut cannot rotate. In the bolt connector consisting of a cover 170 having a shape corresponding to and having a locking jaw 171 at the bottom, the inner surface of the nut housing 110 has a wide diameter of the upper portion and a narrow diameter of the lower portion of the funnel The inclined groove 150 has a shape, but is formed at the lower end of the inclined groove 150 so that the concave groove 151 is formed roundly so that the locking jaw 171 of the cover 170 is caught by the concave groove 151. Become

In addition, the present invention has a configuration to reinforce the nut receiving portion 110 and the lower end portion 120 that can be weakened by the concave groove 151 by a plurality of reinforcing table 140.

Although the present invention has been described by the limited embodiments as described above, the present invention is not limited thereto and the technical spirit of the present invention and a patent to be described below by those skilled in the art to which the present invention pertains. Various modifications and variations will be possible within the scope of the claims.
