In general, rejection refers to a building tool used at a construction site or a construction site to remove nails embedded in wood or concrete, and is also called a presser foot nailing. Exclusion is used when nails are to be removed from the building site or nails must be removed to dismantle the structure. For example, when dismantling a formwork, you can use a cast-out to remove nails. 5 illustrates rejection commonly used in construction sites. As shown in FIG. 5, the rejection 5 includes a foot 51 in the form of a presser foot for fitting a nail N therein, a bag 52 extending from the foot, and a handle 53 formed at the end of the bag 52. do. In order to pull the nail (N) by inserting the head of the protruding nail (N) in the foot 51 and applying a force to the handle 53, the nail is pulled out by the principle of the lever. If nails are pulled out by known exclusion, the nails may stick out in many directions or to a distant location, making it difficult to recover the nails pulled out. And uncollected nails can cause various problems, such as causing accidents at the construction site. In addition, since the force must be pulled out by applying a force to the handle 51, a difficult operation may occur.

The present invention has been made to solve the above problems with known rejection and has the following object.

It is an object of the present invention to provide a rejection that is capable of removing nails upon impact and facilitates recovery of the pulled nails.

According to a suitable embodiment of the invention, the rejection comprises a cylindrical hollow body; At least one fitting groove formed in the longitudinal direction of the hollow body from one end of the hollow body; And an impact portion formed at a predetermined distance in the longitudinal direction of the fitting groove and the hollow body.

According to another suitable embodiment of the present invention, there is provided an apparatus comprising: at least two rejection feet having fitting grooves formed at one end and a shock plate formed at the other end; A fixing portion formed between the fitting groove of the at least two rejection feet and the impact plate and fixing the at least two rejection feet; A fastening portion is formed in which one end is coupled to the fixed portion and includes a rejection head for supporting the impact plate.

Rejection according to the present invention has the advantage that it is easy to remove the nail in the process of dismantling of the formwork, and the recovery of the pulled nail is easy to improve the work efficiency and prevent accidents that may occur in the construction site in advance. . Rejection according to the invention has the advantage, in particular, that it is easy to pull out the nail nailed in the corner part and is advantageous for the removal of nail nailed in the formwork.

Hereinafter, the present invention will be described in detail using the embodiments set forth in the accompanying drawings. The examples presented are exemplary for a clear understanding of the invention and the scope of the invention is not limited to such embodiments.

As shown in FIG. 1, the rejection 10 includes fitting grooves 111 formed at one end of the hollow body 11; An impact portion 112 formed in the middle portion of the body 11; And a thread portion 113 selectively formed at the other end of the body 11. In addition, the rejection 10 may include a lift 12 that is detachably coupled to the body 11 as needed. Lift 12 is a screw coupling portion 122 is coupled to the screw portion 113; The lower portion of the screw coupling portion 122 may include a lifting plate 121 extending in a curved shape having a very large radius of curvature and a lifting groove 122 formed at an end of the lifting plate 121.

The body 11 is in the form of a hollow cylinder and is made of a rigid metal or alloy material. One end of the body 10 has a fitting groove 111 extending downward in the longitudinal direction. The fitting groove 111 has a width W to which the nail can be fitted and can be formed in plural and extend to a length L that is sufficiently large compared to the diameter of the nail. The impact part 112 is a part to which an impact for pulling a nail is applied. The impact can be applied using a high impact tool such as a hammer, for example. Therefore, the impact portion 112 is made of a material such as rubber or plastic that can absorb the impact so as not to damage the body 11 due to the strong impact amount. The impact portion 112 may be made to surround the body 11 in the form of a band. The thread 113 formed at the other end opposite to one end of the body 11 in which the fitting groove 111 is formed may be selectively formed. Substantially the present invention functions as a rejection to pull the nail if there is a fitting groove 111 and the impact portion 112. However, it is necessary to lift the nail slightly if the nail is embedded in the wood or concrete is difficult to fit the nail into the fitting groove (11). In this way, in order to easily fit the nail into the fitting groove 11, the chuck 12 may be detachably coupled to the body 11 as necessary. The thread portion 113 is formed to couple the chuck 12 to the body 11. The thread portion 113 may be a screw of a known type.

The chuck 12 coupled to the other end of the body 11 has a screw engagement portion 122 coupled with the threaded portion 113 at one end. The thread portion 113 and the screw coupling portion 122 may be coupled in a known bolt-thread coupling manner. The connecting ring plate 121 of the threaded portion 122 has a horizontal end E, which is gradually thinner and flattened while extending downward, as shown on the right side (part A) of FIG. 1. Can be. On the other hand, the ring plate 121 may form a plate shape as a whole and may extend downward in a curved form having a large radius of curvature. And the raising groove 122 which can be nailed to the end of the ring plate 121 is formed. As described above, if the end portion of the ring plate 112 is formed in a very thin horizontal plate shape, the nail may be fitted into the ring groove 122 even with a slight force. And you can lift the nail slightly by applying force to the ground.

As described above, the rejection according to the present invention is to insert the nail into the fitting groove 111, and then the impact portion 112 by applying an impact with an object having a large impact amount, such as a hammer to pull out the nail. Since the nail part is located inside the hollow body 11, the pulled nail is bounced into the hollow body without being bounced outward. This allows the plucked nails to be safely collected. The end portion of the hollow body 11 may be modified in various forms. Hereinafter, another embodiment in which the hollow body 11 is modified will be described.

Referring to FIG. 2, a semicircle fitting plate 21 is formed at one end of the hollow body 11 in which the fitting groove 111 is formed. The semicircle fitting plate 21 has a shape of closing a part of one end of the hollow body 11 in a semicircular plate shape having a constant thickness. And the semi-circle fitting plate 21 may form a step (S) and the remaining portion of the hollow body that is not closed. The fitting groove 111 may be formed in any portion of the circumference of the non-closing portion, but as shown in the embodiment of FIG. 2, one edge of the fitting groove 111 may have a vertical edge of the semicircle fitting plate 21. It may be formed to. However, the present invention is not limited by the relative positions of the fitting groove 111 and the semicircular fitting plate 21.

In the case of the embodiment shown in FIG. 1, for example, the nail nailed to the corner is fitted into the fitting groove 111 and the nail is pulled out by applying an impact in a direction parallel to the ground. Likewise, in the case of the embodiment illustrated in FIG. 2, the nail may be fitted into the semicircle fitting plate 21 or the fitting groove 111. A nail is fitted to the semicircle fitting plate 21 and the impact is applied in the horizontal direction with the ground. In the case of the embodiment shown in FIG. 2, it is the same as that of the embodiment shown in FIG. Another embodiment of one end of the hollow body is described below.

Referring to FIG. 3, the rejection 30 includes at least one rejection foot 31 for pulling nails and a fixing portion 312 for securing at least one rejection foot 31; And a rejection head 32 coupled to the fixed portion 312.

A fitting groove 111 is formed at one end of the rejection foot 31 and a disk-shaped shock plate 311 is formed at the other end. And the fixing portion 312 is formed between the fitting groove 111 and the impact plate 311. The fitting groove 111 may be formed in a protruding form, rather than being formed in the hollow body. Since a tool having a large impact amount such as a hammer may be used in the process of removing the nail, the impact plate 311 may be made of a shock absorbing material such as rubber, or a layer of shock absorbing material laminated on the surface to which the impact is applied. May be, but is not limited to this. The fixing portion 312 formed between the fitting groove 111 and the impact plate 311 has a function of stably fixing the rejection foot 31 to the rejection head 32. The fastening portion 311 may be in the form of, for example, wound rigid wire, but may be in any form known in the art, such as welding or riveting.

A fastening portion 321 is formed at one end of the rejection head 32 to secure the rejection foot 31. The impact plate 311 is supported by the rejection head 32. Rejection head 32 may be made of various materials such as wood, aluminum or stainless steel and may be in the form of a cylinder, but need not be hollow. Since the impact plate 311 is supported by the surface of the rejection head 32, the impact plate 311 may preferably be made in a curved shape corresponding to the surface of the rejection head 32. Rejection 30 according to the embodiment of FIG. 3 allows for example to remove nails stuck between narrow gaps. Insert the protruding fitting groove 111 between the narrow gaps and insert the nail between the fitting groove 111. After that, the nail is pulled out by applying an impact to the impact plate 311. Pulled nails can be easily collected because they will fall to nearby places.

In the case of the rejection 30 shown in FIG. 3, the lifter described with reference to FIG. 1 may be coupled to the bottom of the rejection head 32.

As described above, the exclusion according to the present invention not only makes it easier to pull out nailed nails by impacting with a tool such as a hammer, but also allows the nails to be picked up easily.

Figure 4 illustrates the process of pulling a nail by rejection in accordance with the present invention.

The nail N is fitted into the fitting groove 111 or the semicircular fitting plate 21. In the process of pulling out the nail N, all the heads of the nail N are positioned inside the fitting groove 111 or inside the semicircle fitting plate 21, so that the nail N is pulled inside the hollow body 11. Or it will be bounced into the fixing portion 312. And the nail (N) will fall near the lodged. Therefore, it is possible for all plucked nails to be collected.
