Description

Drill bolt for hitting anchor bolts {omitted}

The present invention relates to a drill bit for hitting the anchor bolt, and more particularly, after forming a separate hitting means in the drill bit for drilling the hole while rotating at a high speed, the drill bit in the rotational and linear reciprocating ancard reel bit The present invention relates to a drill bit for drilling an anchor bolt so that the anchor bolt can be securely and securely inserted into a fastening hole drilled in the ceiling surface of a building by a strike device that strikes through the hitting means.

In general, concrete construction uses an anchor bolt as a means for installing structures such as pipe hangers or construction machinery.

In more detail, when a fastening hole is drilled in a vertical direction using a drill bit in a concrete building, an anchor bolt is inserted into the fastening hole. In the anchor bolt as described above, the upper end of the screw rod is screwed and the lower end is connected to the installation structure such as pipe hangers or construction machinery.

When inserting and fixing the anchor bolt having the above purpose into the fastening hole, a metal rod having a proper length is inserted into the anchor bolt in the related art, and then hit the lower end of the metal rod with a hammer so that the anchor bolt is inserted into the fastening hole. .

Therefore, in the prior art, since the hitting operation is carried out with a hammer, not only a lot of force, but also anxious during dangerous work posture, not only dangerous, but also uncomfortable operation, the hammer hitting force was not completely transmitted.

Therefore, the object of the present invention is devised in view of the conventional problems as described above, and after forming a separate striking means in the drill bit for drilling the hole while rotating at a high speed, the rotation and linear reciprocating movement in the ancard reel bit To assemble a drill bit, and to provide an anchor bolt hitting drill bit so that the anchor bolt can be securely and securely inserted into the fastening hole drilled in the concrete building by the striking device that strikes through the hitting means.

In order to achieve the above object, the present invention selects the top of the assembly unit of the drill bit assembly unit and forms a hitting means protruding to the outside of the selected portion, while hitting the hitting device through the hitting means anchor bolt To be fastened securely to the fastening hole,

The striking means is that the integral blow part is formed in the assembly portion when manufacturing the drill bit,

The striking means consists of a prefabricated striking portion having a protrusion formed in the assembly of the drill bit, and a locking inclined portion is formed in the upper end of the passage is inserted into the drill bit and the locking inclined portion is fixed to the turning protrusion at the bottom of the passage. Basic features of the award.

As described above, according to the present invention, a separate hitting means is formed in the drill bit for drilling the hole while rotating at a high speed. The drill bit is assembled in the drill bit to the ancard reel bit rotating and reciprocating the drill bit configured as described above. Is secured and firmly inserted and effective.

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

The anchor bolt of the present invention is also inserted into and fixed in a fastening hole drilled in a vertical direction in a concrete building, and the basic context for allowing various structures to be connected and installed by screwing the screw rod inside the anchor bolt is the same as the conventional art, and used in the present invention. The ancard reel 100 has a structure of rotating and linear reciprocating motion. The technical details of the rotational movement and the linear reciprocating motion of the enclave 100 as described above will be omitted since the detailed description thereof will be omitted.

On the other hand, the drill bit 200 is generally used, and is used to make holes while being fastened and rotated at a high speed, such as an ancard reel 100, and those of various diameters to make holes of various sizes can be made. It is used.

This drill bit 200 is composed of the assembly portion 210 and the blade portion 220, the assembly portion 220 is a portion that is coupled to the encard reel bit 100, the blade portion 220 is substantially a hole It is a part to process.

The present invention has a configuration that is used to fit on the front surface of the ancardi reel 100 to perform a rotary motion and a linear reciprocating motion at the same time. To this end, after selecting the upper part of the assembly unit 210 of the assembly unit 210 of the drill bit 200 and forming the hitting means 300 protruding to the outside of the selected portion, the hitting device through the hitting means 300 (Strong hitting device, set hitting device) is hit so that the anchor bolt (strong anchor bolt, set anchor bolt) is fastened to the fastening hole is configured.

The striking means 300 formed in the drill bit 200 has an integral blow part 310 formed in the assembly portion 210 when the drill bit 200 is manufactured.

On the other hand, the anchor bolt is divided into a set anchor bolt 530 and a strong anchor bolt 430, the striking device suitable for the set anchor bolt 530 and the strong anchor bolt 430, that is, the set hitting device 500 and Strong striking device 400 is used.

The top of the strong striking device 400 has an insertion protrusion 410 is formed so that the strong anchor bolt 430 can be inserted into the bottom, and a space 420 into which the drill bit 200 is inserted is formed.

The top of the set striking device 500 has an insertion groove 510 is formed so that the bottom of the set anchor bolt 530 can be inserted, and a space 520 into which the drill bit 200 is inserted is formed.

In order to use the present invention configured as described above, the striking means 300, that is, the integral striking portion 310 is first formed in the assembly portion 210 of the drill bit 200. Then, when the assembling unit 210 of the drill bit 200 is coupled to the enclave reel 100 and operates the enclave reel 100, the drill bit 200 is rotated and linearly reciprocated by the above-mentioned ancard reel. .

For example, when the strong anchor bolt 430 is used on the side of the fastening hole drilled in the concrete building, the strong striking device 400 is prepared, and the prepared strong striking device 400 is coupled with the drill bit 200. In this case, the drill bit 200 body is disposed in the space 420, and the integral blower part 310 is in close contact with the bottom of the strong striking device 400, and the insertion protrusion 410 is inserted into the strong anchor bolt 430. When operating the ancard reel 100 in the above state, the drill bit 200 by the above-mentioned ancard reel 100 is a rotational and linear reciprocating motion.

In this case, the drill bit 200 rotates in the same direction as the rotation, and the integrated blow part 310 that performs the linear reciprocating motion simultaneously hits the bottom of the strong striking device 400, and the strong anchor bolt 430 in the process of striking. Is inserted and fixed in the fastening hole.

When the set anchor bolt 530 is used at the fastening hole side drilled on the ceiling surface of the building, the set striking device 500 is prepared, and the prepared set striking device 500 is coupled to the drill bit 200. In this case, the drill bit 200 body is disposed in the space 520, and the integral blower 310 is in close contact with the bottom of the set striking device 500, and the insertion groove 510 is inserted into the set anchor bolt 530. When operating the ancard reel 100 in the above state, the drill bit 200 by the above-mentioned ancard reel 100 is a rotational and linear reciprocating motion.

At this time, the integral blow unit 310 that rotates in the same direction as the rotation direction of the drill bit 200 and performs the linear reciprocating motion simultaneously strikes the bottom of the set striking device 500, and sets the anchor bolt 530 in the process of striking. Is inserted and fixed in the fastening hole.
