Description

{Fixing apparatus of electric supply switch box for wiring of building}

The present invention relates to a construction distribution switch box fixing device, and more specifically, to a reinforcing bar clamp fixed across each reinforcing bar arranged horizontally and vertically at a certain width and height, and an axial bolt at one end of which is axially coupled to the reinforcing bar clamp. At the other end of the box, a spacing adjustment member is used to ensure that the box support plate is firmly fixed in a vertical line, and the distribution switch box is simply custom-assembled to the fixed box support plate to securely secure it to an architectural distribution switch box fixing device. It's about.

In general, wires are buried inside the walls of buildings constructed with reinforced concrete for indoor wiring, and after drawing these wires out of the wall, a built-in switch box is installed in the concrete form before concrete pouring to connect to a switch or power outlet. After pouring and curing the concrete in close contact with the inner surface, the form can be removed to install switches, outlets, etc. in the embedded switch box exposed outside the wall.

In order to attach the embedded switch box to the inner surface of the form, conventionally, bolts and nuts are used to connect the reinforcement to the embedded switch box, and the reinforcement is tied to the reinforcing bars placed inside the wall using a binding wire, and then the form is connected to the form. The formwork was installed by welding one side of the auxiliary rebar with the same length as the thickness of the concrete wall to the side or rear of the embedded switch box, and welding the other side of the auxiliary rebar to the placed rebar.

However, although construction using reinforcing materials is easy, the embedded switch box cannot move after it is installed on the rebar, so if an error occurs when installing the form, a gap may occur between the form and the embedded switch box, causing the concrete to break when pouring concrete. A problem occurred where the embedded switch box was buried inside the wall due to penetration into the inside of the switch box. During indoor wiring work, workers had to crush the concrete to expose the buried embedded switch box to the outside, which resulted in cracks on the wall. There was a problem occurring.

In addition, if the embedded switch box protrudes beyond the inner surface of the formwork, the embedded switch box must be struck with a hammer to match the inner surface of the formwork, which has the disadvantage of damaging the embedded switch box in this process.

In addition, installation by welding is done by welding to reinforcing bars in consideration of the thickness of the concrete wall, so it matches the inner surface of the form relatively well. However, if the form is tilted or the thickness changes due to construction errors, the position of the embedded switch box may change. Not only was there a problem of having to hit it with a hammer to change it, but there was also the inconvenience of having to mobilize equipment for welding.

In the embedded switch box fixing device for buildings registered in Patent No. 0778289 (November 15, 2007), a rebar fixing arm is connected to the left and right vertical rebars, a leaf spring is hinged to this rebar fixing arm, and both rebars are fixed. The switch box is connected to the arm by connecting a four-bar link, guide plate, and compression spring.

Therefore, by using leaf springs, compression springs, and multiple links to allow the embedded switch box to move freely in the forward and backward directions, the embedded switch box can maintain the shape of the form even when the inner surface of the form and the embedded switch box are not parallel. It was made to adhere closely to the inner surface to prevent concrete from penetrating into the embedded switch box during concrete pouring.

However, in the prior art, only the left and right vertical reinforcing bars are fixed by elastic clamps on both sides, so the elastic clamps easily move downward during concrete pouring, making accurate installation in the correct position difficult during concrete pouring, and the fixing force of the embedded switch box is low. There is a disturbing problem.

However, the ends of the pair of extension parts (12) may be spread outward between the ends as shown in the drawing to facilitate insertion of the reinforcing bar (RF), and the reinforcing bar (RF) A cushion pad such as rubber may be attached to the inner peripheral surface of the coupling portion 11 that is in close contact with the RF.

In the rebar clamp 10, bolt holes 13 are formed in a pair of extension parts 12 on the same straight line to penetrate the plate surface with a certain diameter, and a bolt hole 13 is formed in the plate surface on one side. A screw block 14 forming a screw hole 140 with a diameter equal to or smaller than is attached to the outside of the plate.

The extension portion 12 of the rebar clamp 10 is screwed to the screw block 14 along with the bolt holes 13 on both sides and the shaft bolt 20 is connected so as to penetrate the screw block 14.

That is, the shaft bolt 20 is formed in the shape of a shaft of a certain length with a male thread formed on the outer peripheral surface, and a tightening nut 21 that allows the shaft bolt 20 to be rotated using a tool is integrally located in the middle of the length.

(23) is formed.

The spacing adjustment shaft portion 23 of the shaft bolt 20 connected to each rebar clamp 10 has a penetration of a size identical to or larger than the outer diameter of the spacing adjustment shaft portion 23, although the shape is the same as the spacing adjustment shaft portion 23. The spacing adjustment member 30 forming the hole is inserted.

The spacing adjusting member 30 is a spacer formed to a certain thickness, and an assembly hole 31 having the same shape as the cross section of the spacing adjusting shaft portion 24 is formed in the center of the spacing adjusting member 30, so that the spacing adjusting shaft portion 24 ) is axially coupled to prevent rotation.

Since the vertical and horizontal reinforcing bars (RF) at the positions where the reinforcing bar clamps (10) are connected are arranged so that they are not installed on the same vertical line, the spacing adjustment shaft portion (23) of the shaft bolt (20) is axially coupled to each reinforcing bar clamp (10). ), one or more spacing adjusting members 30 are coupled so that the cross sections of the distalmost spacing adjusting members 30 are located on the same vertical line.

A cross-shaped box support plate 40 is connected to the spacing adjusting shaft portion 23 so that the distal spacing adjusting members 30 are positioned on the same vertical line.

At this time, the box support plate 40 is formed in the shape of a cross, and long fixing holes 41 that open outward are formed on both sides and the upper and lower plate surfaces, and are vertically and horizontally formed through these fixing holes 41. The end of the spacing adjustment shaft portion 23, which is axially coupled to each reinforcing bar clamp 10 respectively coupled to the formed reinforcing bars (RF), penetrates, and the shaft bolt 20 protrudes through the fixing hole 41. A fixing nut (42) is screwed to the end so that it is firmly fixed to the shaft bolt (20).

In addition, at the center of the plate surface of the box support plate 40, a square or hexagonal dowel protrusion 43 is formed to protrude at a certain width, and at the center of the dowel protrusion 43 is a box fixing shaft 44 of a predetermined length. Make it protrude.

For this purpose, as shown in FIG. 4, a fitting groove 51 is formed on the back of the distribution switch box 50 to correspond to the fitting protrusion 43 formed on the box support plate 40, and the center of the fitting groove 51 is formed. A shaft through hole 52 is formed so that the box fixing shaft 44 penetrates, and a box fixing nut 53 is screwed to the box fixing shaft 44 penetrating the shaft through hole 52.

However, the end of the spacing adjustment shaft portion 23 of the shaft bolt 20, in which one or more spacing adjustment members 30 are axially coupled to each vertical and horizontal shaft bolt 20, is attached to the box support plate 40 as shown in FIG. 5. ) and at the same time penetrate the rear surface of the distribution switch box 50, which is fitted to the box support plate 40, and protrude into the inside of the distribution switch box 50, and each of the spacing adjustment shaft portions 23 A fixing nut 42 may be coupled to the protruding end so that the box support plate 40 and the distribution switch box 50 can be fixed at the same time.

As in the above configuration, the operation and effect of the architectural distribution switch box fixing device according to the present invention will be described in more detail as follows.

The present invention relates to a reinforcing bar clamp (10) that is respectively fixed to vertical and horizontal reinforcing bars (RF) provided on the top, bottom, and both sides that are pre-reinforced before manufacturing the form during building construction, and a rebar clamp (10) connected to these reinforcing bar clamps (10). Ensure that the distribution switch box (50) is firmly fixed to the box support plate (40) that is axially coupled to the shaft bolt (20).

In other words, at the location where the distribution switch box 50 is to be installed before pouring the concrete, it is simultaneously connected to a plurality of reinforcing bars (RF) formed vertically and horizontally at a certain height and at a certain distance on both sides, thereby making the distribution switch box more robust. This is to enable installation of (50).

In particular, since the vertical and horizontal reinforcing bars (RF) are formed front and back at the intersection points, they are not located on the same vertical line, so this positional deviation between the reinforcing bars (RF) can be eliminated.

To explain this in more detail, the reinforcing bar clamps 10 are connected from the top to the horizontal upper and lower reinforcing bars (RF) spaced at a certain height, and are installed to be spaced a certain width in front or behind the upper and lower reinforcing bars (RF). Ensure that the reinforcing bar clamps (10) are connected to the reinforcing bars (RF) on both sides in the vertical direction.

At this time, the rebar clamp 10 is connected to the horizontal rebar (RF) from the top, and the vertical rebar (RF) is connected from the outside to the inside or from the inside to the outside in corresponding directions as shown in the drawing. do.

In this way, the reinforcing bar clamp 10 connected to each reinforcing bar (RF) has a clamp fixed shaft portion 22 based on the tightening nut 21 of the shaft bolt 20 through the bolt hole 13 formed in each extension portion 12. ) is screwed on one side of the extension part 12 to the screw block 14 integrally connected to the outer surface.

The axis bolt (20) allows the tightening nut (21) to be simply rotated by hand or using a separate tool, and at this time, one side of the tightening nut (21) is in close contact with one side extension (12) of the rebar clamp (10). If possible, the reinforcing bar clamp 10 is prevented from being separated from the reinforcing bar (RF) by the coupling portion 11 of the reinforcing bar clamp 10 and the shaft bolt 20.

Therefore, when the tightening nut 21 is simply tightened, the reinforcing bar clamp 10 is firmly fixed to the reinforcing bar (RF), and the spacing adjustment shaft portion of the shaft bolt 20 extending from the reinforcing bar clamp 10 coupled in this way At (23), a plurality of spacing adjustment members 30 are axially coupled.

In addition, the reinforcing bar clamp 10 is connected to the reinforcing bars (RF) arranged in the horizontal direction on the upper and lower sides as well as the reinforcing bars (RF) arranged in the vertical direction on both sides on the same horizontal line. In this case, the reinforcing bar clamp 10 is It should be connected from the outside or inside of the rebar (RF).

The distalmost spacing member (30) is axially coupled to the upper and lower spacing adjusting shaft portions (23) while allowing the spacing adjusting member (30) to be axially coupled to the spacing adjusting shaft portion (23) extending from each rebar clamp (10) on both sides. Make sure they all end on the same vertical line.

In this way, the spacing adjusting members 30 are axially coupled to the spacing adjusting shaft portion 23 protruding and extending from the reinforcing bar clamps 10 on the upper, lower, and both sides, and the cross sections of the distalmost spacing adjusting members 30 are on the same vertical line. When formed, each spacing adjustment shaft portion 23 is opened toward the end of the cross-shaped extending plate surface of the box support plate 40 and penetrates through the fixing hole 41 on the same horizontal line formed in a long hole shape.

However, the upper end of the fixing hole 41 on the lower end of the box support plate 40 is seated on the spacing adjusting shaft 23, and the spacing adjusting shaft 23 is attached to the fixing hole 41 on the upper end of the box support plate 40. Let it penetrate.

At this time, the reinforcing bar clamp 10 is positioned so that the spacing adjustment shaft portion 23 penetrates the fixing hole 41 formed on both sides of the box support plate 40, and then the tightening nut 21 is tightened to secure the reinforcing bar (RF). Make sure it is firmly fixed.

In this way, when each spacing adjustment shaft portion 23 penetrates through each fixing hole 41 of the box support plate 40, the box support plate 40 prevents movement up and down and sideways on a vertical line.

When the box support plate 40 is connected and the fixing nut 42 is fastened to the end of each spacing adjustment shaft portion 23, the box support plate 40 is firmly fixed.

Finally, the distribution switch box 50 is connected so that the fitting groove 41 is connected to the fitting protrusion 43 formed to protrude at a certain width in the center from the front of the box support plate 40, and then the fitting protrusion 43 is connected. After allowing the box fixing shaft 44 protruding from the center of the box to penetrate the shaft penetration hole 52 formed in the center of the plate surface of the fitting groove 41, the box fixing shaft 44 is installed inside the distribution switch box 50. By combining the box fixing nut 53, the distribution switch box 50 can be firmly fixed.

In particular, if each spacing adjustment shaft portion 23 penetrates not only the box support plate 40 but also the back of the distribution switch box 50, each spacing is adjusted together with the box fixing nut 53 inside the distribution switch box 50. Since the distribution switch box 50 can be fixed using the fixing nut 42 fastened to the shaft 23, a more robust installation is possible.

In this way, the reinforcing bar clamps 10 are fixed to the reinforcing bars (RF) on all sides, and the box support plate 40 is fixed to the other end of the shaft bolt 20, one end of which is screwed to each reinforcing bar clamp 10, so as not to move. Since the distribution switch box 50 can be simply fixedly coupled to this box support plate 40, it is possible to install the distribution switch box 50 not only more quickly and easily, but also firmly in the correct position.

Therefore, even if concrete is poured by erecting a form with the distribution switch box 50 installed, the distribution switch box 50 is firmly supported by the reinforcing bars (RF) on all sides, so it does not deviate from its position or move due to the load of the concrete. There is a very useful effect of being able to install it stably in the correct position without any problems.

As such, the present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and changes can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should be considered to fall within the scope of the claims of the present invention.
