Abstract

The present invention relates to a reinforcing bar for fixing a wall attachment. According to the present invention, temporary fixation is performed by screwing on the outside of the wall, and when the fixing block is erected through bolt rotation and then moves forward, the fixing block adheres to the inner surface of the wall to exert a solid fixing force not only on the outside of the wall but also on the inside of the wall. Therefore, since solid fixation can be made inside and outside the wall, solid support is possible when the attachment using the reinforcing bar is fixed.

Description

Reinforcement bar for fixing attachments to walls}

The present invention relates to a reinforcing bar for fixing a wall attachment, and more particularly, to a technology for firmly fixing it inside as well as outside a wall.

An outlet is used to supply power applied to buildings and homes to electric appliances, and is standardized to a predetermined size and is mainly used in a form of being installed partially embedded in a wall.

In general, an outlet is manufactured with a structure including a housing having a structure through which an electric wire can be introduced, an outlet terminal inserted into the housing and into which a plug is plugged, and a plate fixedly coupled to an inlet of the housing in a state where the outlet terminal is fixedly supported. Here, the plate is fixedly coupled to the housing by coupling means such as screws or bolts.

In addition, in order to install the outlet on the wall, a groove is dug in a certain part of the wall, wiring is performed through the groove, and the outlet is installed at the end of the wire. To install the outlet, a bracket installed in the groove of the wall and the outlet are bolted together.

However, even if the outlet is fixed to the bracket installed in the groove of the wall using screws or bolts, there is a problem in that the holding force is weak because the fastening is performed only outside the wall. Of course, if screws or bolts are combined inside the wall, more solid fixation is possible, but the size of the outlet is small, so it is impossible to insert tools through the grooves in the wall to tighten the screws.

Of course, in the case of an outlet, since it does not support a heavy object, it is not a big problem even if it is fixed through screwing only on the outside of the wall. However, in the case of a structure that is partially embedded in a wall and fixes an attachment, such as a set-top box, a wire box, an alarm device, and the like, a more robust fixing force must be secured.

On the other hand, as a prior art related to a device for fixing an attachment to a wall, there is Republic of Korea Patent Publication No. 10-2013-0020463 (February 27, 2013, 'wall attachment fixing device').

The present invention has been devised to solve the problems of the prior art as described above, so that the fixing force can be exerted not only outside the wall but also inside the wall, so that even when a relatively heavy object is attached, a solid fixation is possible. Its purpose is to provide.

Reinforcing rod for fixing wall attachments according to the present invention for achieving the above object is exposed to the outside of the wall body and has a bolt hole formed thereon; a bolt supporter extending to the rear of the main body, having a block shifting hole communicating with the bolt hole, and having a slot formed in the block shifting hole in an outward direction around the main body; a bolt rotatably seated in the block movement hole of the bolt support; and a fixing block that is screwed with the bolt and moves forward and backward along the slot portion of the bolt support when the bolt rotates.

According to the reinforcing bar for fixing wall attachments according to the present invention, temporary fixation is performed through screw fastening from the outside of the wall, and when the fixing block is erected through bolt rotation and then moves forward, the fixing block adheres to the inner surface of the wall. Solid fixing force is exerted not only on the outside of the wall but also inside the wall. That is, since solid fixation can be made inside and outside the wall, solid support is possible when the attachment using the reinforcing bar is fixed.

In particular, in the present invention, since the rear part of the block shifting hole formed in the bolt support has a stepped structure, when the bolt is tightened a little more after the close contact part of the fixing block is in close contact with the wall, a part of the bolt is elastically deformed by slightly bending downward due to the repulsive force generated between the close contact part of the fixing block and the wall, and the fixing block also undergoes elastic deformation. Due to the elastic deformation of these bolts and fixing blocks, the reinforcement bar is firmly fixed to the wall.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, some configurations irrelevant to the gist of the present invention will be omitted or compressed, but the omitted configurations are not necessarily unnecessary in the present invention, and can be combined and used by those skilled in the art to which the present invention belongs.

1 is a perspective view for explaining a reinforcement rod for fixing a wall attachment according to an embodiment of the present invention, FIG. 2 is a perspective view of the reinforcement rod shown in FIG. 1 viewed from another angle, and FIG. As shown in Figures 1 to 3, the reinforcement 100 for fixing the wall attachment according to the embodiment of the present invention (hereinafter referred to as 'reinforcement') includes a main body 110, an entry portion 120, a bolt support 130, a bolt 150 and a fixing block 140.

The main body 110 is a portion exposed to the outside when the reinforcing bar 100 is mounted on the mounting hole 11 formed in the wall 10, and is made of a substantially rectangular shape, and an inlet hole 112 is formed to insert wires or other attachments to the inside. In addition, since a plurality of screw holes 111 are formed around the body 110, the reinforcing bar 100 is attached to the mounting hole 11 of the wall 10 as shown in FIG. However, fastening using screws supports the reinforcing bar 100 only outside the wall 10, and in this embodiment, an additional configuration capable of supporting the reinforcing bar 100 even inside the wall 10 is provided.

Meanwhile, bolt holes 113 penetrating front and rear are formed in the upper and lower parts of the main body 110, and the bolt holes 113 communicate with the block moving holes 131 of the bolt support 130 to be described later. In addition, a jaw smaller than the diameter of the head of the bolt 150 is formed at a portion where the bolt hole 113 and the block movement hole 131 are connected, so that the bolt 150 is prevented from escaping backward.

The entry part 120 is formed at the rear of the main body 110 (hereinafter, when the reinforcement 100 is mounted on the wall 10, the outer direction of the wall 10 is referred to as 'front', and the inner direction of the wall 10 is referred to as 'rear'. It is formed in a form protruding along the circumference of the inlet hole 112). This entry part 120 is a part that comes into contact with the inner circumference of the mounting hole 11 when the reinforcement bar 100 is mounted on the wall 10.

The bolt support 130 is formed in a shape extending backward from the main body 110 and the entry portion 120, and a block movement hole 131 is formed on the inside in a shape penetrating the front and rear. Here, the block movement hole 131 is connected to the bolt hole 113 formed in the body 110. 6, the part adjacent to the bolt hole 113 has an inner diameter almost the same as the outer diameter of the bolt 150, and a part to the left of the block moving hole 131 has an inner diameter almost equal to the cylindrical outer diameter of the coupling part 141 of the fixing block 140. The lower part of the inner diameter surface (see FIG. 6) is stepped downward to form a recessed surface 136 that is depressed downward. The recessed surface 136 has the shape of a cylindrical curved surface. A plurality of minute protrusions 137 are formed on the recessed surface 136 .

In addition, a slot portion 132 is formed along the longitudinal direction of the block movement hole 131 on a side surface facing outward from the bolt support body 130 . Referring to the bolt supporter 130 installed on the top of the reinforcing bar 100 in FIG. 2, the slot portion 132 is formed on the upper side of the bolt supporter 130. In addition, some regions of the structures on both sides of the rear of the slot portion 132 of the bolt support 130 are cut toward the inside of the main body 110 to form an open portion 133 . At this time, on the side facing the portion where the opening 133 is formed in the slot portion 132, there is a locking jaw 134 that prevents the extension 143 of the fixing block 140 from further rotating. The locking jaw 134 is on the extension of the side wall of the slot portion 132.

The bolt 150 enters through the bolt hole 113 of the body 110 and is installed in a state extending to the block movement hole 131 of the bolt support 130.

The fixing block 140 is provided to fix the reinforcing bar 100 inside the wall 10. This fixing block 140 is largely divided into a coupling part 141, an extension part 143 and a close contact part 144.

The coupling portion 141 has a cylindrical shape fastened to the bolt 150, and coupling holes 142 penetrating in front and rear are formed. In addition, a screw thread is formed in the coupling hole 142, so that it is screwed with the bolt 150. The extension part 143 is manufactured in a plate shape extending from the outer surface of the coupling part 141, and an incision groove 143a is formed at an approximate center point of the extension part 143. At the end of the extension part 143, a contact part 144, which is a part that comes into close contact with the inner surface of the wall 10, is formed.

The reinforcing bar 100 according to the embodiment of the present invention described above will be further embodied through the description of the reinforcing bar mounting process to be described with reference to FIGS. 6 to 9 below.

To install the reinforcement bar 100, a mounting hole 11 is first formed in the wall 10. The size of the mounting hole 11 should be smaller than the size of the outer circumference of the main body 110 and larger than the size of the outer circumference of the entry portion 120. Therefore, as shown in FIG. 1, after the bolt support 130 and the fixing block 140 of the reinforcing bar 100 face the inside of the wall 10, and then the reinforcing bar 100 enters the mounting hole 11, the bolt support 130, the fixing block 140, and the entry part 120 enter the mounting hole 11 as shown in FIG. 3, and the main body 110 cannot enter the mounting hole 11. There is no wall (10) becomes a state exposed toward the outside. Here, when the reinforcing rod 100 enters the mounting hole 11, the extension 143 and the close contact 144 of the fixing block 140 should be in a state of lying sideways as shown in FIG.

As shown in FIG. 3, when a screw (not shown) is screwed into the screw hole 111 of the main body 110 in a state where the reinforcing bar 100 enters the mounting hole 11 of the wall 10, the reinforcing bar 100 and the wall 10 are temporarily fixed.

Then, as shown in FIG. 4, by turning the head of the bolt 150 exposed to a portion of the inner region of the main body 110 using a screwdriver (or power tool), internal fixation using the fixing block 140 can be achieved. 4 and 5 are views of the fixing block 140 moving according to the rotation of the bolt 150 from different angles, but the wall 10 is not shown in FIGS. 4 and 5 so that the main configuration can be clearly seen.

4(a) and 5(a), before the bolt 150 is rotated, the extension part 143 and the close contact part 144 of the fixing block 140 lie sideways. That is, the coupling part 141 of the fixing block 140 is coupled to the end of the bolt 150, but the extension 143 extending from the coupling part 141 is the block movement hole 131 of the bolt support 130. It can be laid down through the opening 133 formed by cutting to the side at the end.

In this state, when the bolt 150 is rotated, the coupling part 141 rotates, and the extension part 143 and the contact part 144 are erected as shown in FIGS. 4(b) and 5(b).

Since the bolt 150 and the coupling portion 141 are screwed together, a certain level of frictional force exists between the bolt 150 and the coupling portion 141 . Therefore, when the bolt 150 rotates, the coupling part 141 rotates together, so that the entire fixing block 140 rotates.

Therefore, as shown in FIG. 4 (b) and FIG. 5 (b), when the bolt 150 rotates, the fixing block 140 rotates together, but the side of the extension part 143 of the fixing block 140 is bolt support. Then, when the bolt 150 is additionally rotated, only the bolt 150 rotates in a state in which the fixing block 140 including the coupling part 141 cannot rotate any more. Therefore, when the bolt 150 rotates in the state of FIG. 5 (b), the fixing block 140 screwed to the bolt 150 moves forward toward the head of the bolt 150.

That is, as shown in (c) of FIG. 5, the fixing block 140 moves toward the head of the bolt 150 according to the continuous rotation of the bolt 150. At this time, the extension part 143 is the bolt support 130. It moves along the longitudinal direction of the slot part 132 formed on the upper surface. Of course, since one side of the extension part 143 maintains a state in close contact with one side of the slot part 132 starting from the locking jaw 134, rotation is impossible and only forward movement is possible.

6 and 7, when the bolt is additionally rotated in a state in which the contact portion 144 of the fixing block 140 is in close contact with the inner surface of the wall 10, the fixing block 140 receives a repulsive force from the inner surface of the wall 10, and the fixing block 140 is strongly pushed in the rear direction (left direction with reference to FIG. 7). At this time, the fixing block 140 undergoes elastic deformation in which the upper part of the incision groove 143a of the extension part 143 is bent to the left with reference to FIG. Since the part with the smallest cross-sectional area of the extension part 143 of the fixing block 140 is the part where the incision groove 143a is formed, this part is deformed.

At the same time, when the fixing block 140 receives the repulsive force of the wall 10 in the rear direction (left direction with reference to FIG. 7) and is strongly pushed, the bolt 150 undergoes elastic deformation that is bent somewhat downward. When the bolt 150 is continuously rotated further, the lower end of the coupling part 141 of the fixing block 140 coupled to the bolt 150 comes into contact with the recessed surface 136 of the rear part of the convex moving hole 131.

When the bolt 150 is bent and the coupling portion 141 of the fixing block 140 descends downward so that the lower end of the coupling portion 141 comes into close contact with the recessed surface 136, the lowermost portion of the coupling portion 141 of the fixing block 140 is caught by the protrusions 137 of the recessed surface 136 so that the fixing block 140 is not pushed to the left with reference to FIG. 7. Since the retraction of the fixing block 140 is prevented by the protrusions 137, the fixing block 140 maintains a state of being strongly adhered to the inner surface of the wall 10. Here, the lowest end of the coupling part 141 is a cornered portion, and since it has an angular structure, it can be caught on the protrusions 137 . As a result, since the fixing block 140 maintains a strong adherence to the wall 10, the fixing of the reinforcing bar 100 to the wall 10 is not loosened. Therefore, even if an external force acts on the reinforcement rod 100, the reinforcement rod 100 does not shake and maintains a solid fixed state.

In addition, even after the fixing block 140 adheres to the wall 10, the bolt 150 continues to rotate, so that the fixing block 140 is pushed to the left with respect to FIG. 7 by the repulsive force of the wall 10, so that the bolt 150 elastically deforms and bends somewhat downward in FIG. Even if it does not adhere to the recessed surface 136 and is in a floating state, since the bolt 150 is already elastically deformed and is in a bent state, the fixing block 140 is in close contact with the wall 10 by the restoring force according to the elastic deformation of the bolt 150. Therefore, the reinforcing bar 100 is always fixed to the wall 10 in close contact without any play and is not loosened.

In addition, when the fixing block 140 presses the wall 10, since the wall 10 receives a repulsive force, elastic deformation occurs at the cutout groove 143a having the smallest cross-sectional area in the fixing block 140, and the fixing block 140 adheres to the wall 10 by the restoring force according to the elastic deformation at the cutout groove 143a portion. Therefore, the fixing of the reinforcing rod 100 to the wall 10 always maintains a close contact state and does not loosen.

In addition, the threaded connection between the coupling part 141 of the fixing block 140 and the bolt 150 is due to the elastic deformation of the bolt 150 and the restoring force due to the elastic deformation of the fixing block 140, so that the threads of both are more closely attached to each other, so that the loosening of the screws between the fixing block 140 and the bolt 150 is prevented. Since loosening of the screws of the fixing block 140 and the bolt 150 is prevented even when an external impact is applied, the tightness of the reinforcing bar 100 to the wall 10 is maintained well and does not come loose.

As described in detail above, the reinforcement bar 100 for fixing the wall attachment according to the present invention is temporarily fixed by screwing on the outside of the wall 10, and when the fixing block 140 is erected through the rotation of the bolt 150 and then moves forward, the fixing block 140 adheres to the inner surface of the wall 10, so that a solid fixing force is exerted not only on the outside of the wall 10 but also on the inside of the wall 10. That is, since solid fixation can be made inside and outside the wall 10, solid support is possible when the attachment using the reinforcing bar 100 is fixed.

In particular, in the present invention, since the block moving hole 131 is provided with a recessed surface 136 that is stepped to form an additional space, so that the elastic deformation of the bolt is possible, the restoring force due to the elastic deformation of the bolt makes the fixing block more closely attached to the wall, thereby making the reinforcement more secure.

Meanwhile, in the above description, the reinforcing rod 100 provided with the rectangular body 110 has been illustrated and described, but the shape of the body may have various shapes as needed.

In addition, in this embodiment, although the bolt support 130, the fixing block 140, and the bolt 150 are respectively provided only on the upper and lower portions of the main body 110, an example is shown, but according to the practice, the bolt support, the fixing block and bolts can be variously modified in the formation position or number of formations.

Preferred embodiments of the present invention described above have been disclosed for the purpose of illustration, and those skilled in the art with ordinary knowledge of the present invention will be able to make various modifications, changes and additions within the spirit and scope of the present invention, and such modifications, changes and additions will be regarded as falling within the scope of the claims of the present invention.
