1 to 6, a reinforcing bar spacer capable of guiding a concrete pouring height according to an embodiment of the present invention may include a support unit 100 and a height guide unit 200.

First, the support unit 100 may serve to support the reinforcing bars 10 installed on the bottom surface of the formwork before the concrete is poured away from the bottom surface of the formwork.

The support unit 100 may include a support body portion 110 and a support leg portion 120.

The support body 110 may be formed in a ring shape in a direction parallel to the bottom surface, and a plurality of ribs may extend in a direction perpendicular to the bottom surface to form a support body 110 in the upper portion of the ring. And, the upper portion of the support body portion 110, that is, the upper portion of the plurality of ribs may be provided with a seating portion 130 on which the reinforcing bar 10 is seated. In the seating portion 130, a reinforcing bar seating groove for forming a more stable seating of the reinforcing bar 10 may be formed, but the reinforcing bar seating groove may be formed without being formed.

And, the support body portion 110 may be formed with a coupling groove 113 formed in a groove shape on both sides of the position adjacent to the seating portion 130. Coupling grooves 113 may be formed on both sides of the support body portion 110 corresponding to the direction perpendicular to the longitudinal direction of the reinforcing bar 10 seated on the seating portion 130. The reason that the coupling groove 113 is formed on both sides of the support body portion 110 corresponding to the direction perpendicular to the longitudinal direction of the reinforcing bar 10 is that the coupling body portion 210 of the height guide unit 200 to be described later is the reinforcing bar ( 10) is to be coupled to the support body 110 without interference of the reinforcing bar 10 in the covered state.

Then, the coupling groove 113 may be formed to have an inclination toward the inner upper side of the support body 110.? 袖 *. The slope of the coupling groove 113 is easy after the coupling protrusion 211, which will be described later, is fitted. It can be prevented from being removed.

A plurality of seating columns 111 may be formed along the outer circumferential surface of the seating portion 130 on the upper portion of the support body portion 110. The plurality of seating columns 111 may serve to guide the seating direction of the reinforcing bars 10 by being positioned in the reinforcing bars 10 between the seating columns 111. In addition, a seating piece 112 formed toward the reinforcing bar 10 positioned between the seating columns 111 may be formed in the seating column 111. The seating piece 112 is seated on the seating portion 130 and may serve to fix the reinforcing bar 10 positioned between the seating columns 111.

A support leg portion 120 may be formed under the support body portion 110. The support leg portion 120 is formed in a plurality of leg shapes, and may serve to support the support body portion 110 to be spaced apart from the bottom surface.

The height guide unit 200 is coupled to the upper portion of the support unit 100 and serves to guide the height at which concrete is to be cast, and may be formed of a coupling body part 210 and a height guide part 220.

The coupling body portion 210 may be formed by extending both ends roundly toward both sides of the supporting body portion 110 from the upper portion of the supporting body portion 110. For example, the coupling body portion 210 may be formed in a hollow state with both ends extending roundly.

If the shape of the coupling body portion 210 is described in more detail, the coupling body portion 210 may be formed in the form of a semicircular plate cut from the center of the hollow plate. In addition, the coupling body portion 210 formed in the form of a semicircle is formed in a hollow shape, and when the coupling body portion 210 and the supporting body portion 110 are combined, the coupling body portion 210 is hollowed. Inside the seating portion 130 of the support body 110 may be located. In addition, the coupling body portion 210 may serve to support the height guide portion 220 installed on the upper portion.

Coupling protrusions 211 for engaging the coupling grooves 113 formed on both sides of the support body portion 110 may be protruded at both extended ends of the coupling body portion 210. The engaging projection 211 may be formed as an outer peripheral surface corresponding to the inner peripheral surface of the engaging groove 113 of the support body portion 110.

For example, the engaging groove 113 is inclined toward the inner upward direction of the support body portion 110, and the outer peripheral surface of the engaging projection 211 is formed of an inclined surface 212 corresponding to the engaging groove 113, so that the engaging body When the part 210 is coupled to the support body part 110, it is possible to prevent the coupling body part 210 from being detached from the support body part 110 in the opposite direction of engagement.

In this embodiment, since the coupling body portion 210 is hollow inside, both extended ends may be formed to have a predetermined elasticity. For example, when the coupling body portion 210 is fitted toward the support body portion 110 in a state where it is positioned on the upper portion of the support body portion 110, both ends of the coupling body portion 210 are opened toward the outside by a predetermined distance Losing, when the engaging protrusion 211 is fitted into the engaging groove 113, both ends of the engaging body portion 210 are restored to the original position, so that the engaging protrusion 211 can be fixed to the engaging groove 113.

In addition, the coupling body portion 210 may be formed with an upper seating groove 213 having an inner circumferential surface corresponding to the upper outer circumferential surface of the reinforcing bar 10 on the hollow inner upper portion. The upper seating groove 213 may be in close contact with the upper portion of the outer circumferential surface of the reinforcing bar 10 seated on the seating portion 130 when the supporting body portion 110 and the engaging body portion 210 are combined.

In addition, the upper seating groove 213 may be formed to have magnetic properties. For example, the upper seating groove 213 may be magnetically coupled with the upper portion of the rebar 10 seated on the seating portion 130 when the engaging body portion 210 is coupled to the support body portion 110. That is, the coupling body portion 210 and the support body portion 110 is primarily coupled by the engaging projection 211 and the engaging groove 113, the upper seating groove 213 is secondary to the reinforcing bar 10 By magnetic coupling, the coupling body portion 210 can be more firmly coupled to the support body portion 110.

That is, since the coupling body portion 210 is doubled by the coupling protrusion 211 and the upper seating groove 213 having magnetism, it is more firmly coupled to the support body portion 110, and accordingly, the coupling body portion ( The height guide unit 220 installed on the upper portion of the 230 can be prevented from being inclined by external force, thereby minimizing the error in guiding the concrete pouring height due to the inclination of the height guide unit 220.

The height guide unit 220 is installed on the upper portion of the coupling body portion 210, and the coupling body portion 210 is guided to the pouring height of the concrete through the level member 223 in the state coupled to the support body portion 110 Can play a role.

The height guide unit 220 may include a first standing portion 221, a second standing portion 222 and a level member 223.

The first standing portion 221 may be formed in a tube shape with a thread formed on an inner circumferential surface. The first standing portion 221 may be formed such that one side is connected to the upper portion of the coupling body portion 210 and the other side extends in a vertical direction from the bottom surface.

In one embodiment, a horizontal member may be formed on the outer surface of the first standing portion 221. The horizontal member may serve to check whether the first standing portion 221 stands in a vertical direction from the bottom surface.

The second standing portion 222 may be formed in a tube shape having a diameter smaller than the diameter of the first standing portion 221. In addition, the second standing portion 222 may be formed on the outer peripheral surface with a thread corresponding to the thread formed on the inner peripheral surface of the first standing portion 221.

The second standing portion 222 is engaged with the thread of the first standing portion 221 in a state where the inside of the first standing portion 221 is drawn in, and moves up and down from the first standing portion 221 through rotation. can do. And, the other side of the second standing portion 222 is adjusted to the degree of protruding from the first standing portion 221 according to the elevation and descending of one side of the second standing portion 222 to adjust the overall height of the height guide portion 220 Can be adjusted.

For example, as shown in FIGS. 5 (A) and 5 (B), the second standing portion 222 is a height guide portion (depending on how much is introduced or projected into the first standing portion 221). The total length of 220) can be adjusted.

The level member 223 may be located on the other outer circumferential surface of the second standing portion 222. The level member 223 may be moved up and down in the longitudinal direction of the second standing portion 222 by being engaged with a thread formed on the outer circumferential surface of the second standing portion 222. The level member 223 may serve to guide the pouring height of concrete by providing visibility to the worker.

When the level member 223 is described in more detail, the level member 223 may include a lifting plate 223A and a level piece 223B.

The lifting plate 223A may be formed in a circular plate shape through which the center is penetrated. In addition, a thread corresponding to the thread formed on the outer circumferential surface of the second standing portion 222 may be formed on the inner circumferential surface of the through center of the elevating plate 223A. That is, the lifting plate 223A is screwed to the outer circumferential surface of the second standing portion 222 and can be moved up and down from the second standing portion 222 by rotation.

A level piece 223B may be formed on the outer circumference of the seunggal plate. One side of the level piece 223B is connected to the outer circumference of the lifting plate 223A, and the other side of the level piece 223B can be extended toward the top. The level pieces 223B formed as described above may be formed to be spaced apart from each other along the outer circumference of the lifting plate 223A.

The level piece 223B may serve to guide the pouring height of concrete to the worker by elevating and descending from the second standing portion 222 along the elevating plate 223A. For example, the worker can pour concrete up to the top of the level piece 223B.

The level piece 223B may be formed of a material whose angle is adjusted by external force, and an unfolding angle of the level piece 223B may be adjusted by an operator. That is, the level piece 223B can finely adjust the pouring height of concrete according to the degree of unfolding.

In this embodiment, the level member 223 may be provided with any one of a reflective member, a luminous member, or a light emitting member on its surface. Therefore, the level member 223 can provide high visibility to a worker in a remote location. In addition, the level member 223 may provide high visibility to the operator even at night due to one of the reflective member, the luminous member, or the light emitting member.

Therefore, the reinforcing bar spacer capable of guiding the concrete pouring height of the present invention controls the overall height of the height guide unit 220 through the first standing portion 221 and the second standing portion 222, and the level member 223 Through this, once again, the height of the concrete is adjusted, so there is an advantage that the height of the concrete can be finely adjusted.

In addition, before the height guide unit 200 is installed at the construction site, the second standing portion 222 is maintained inside the first standing portion 221, and the second standing portion only when installed on the site ( 222) because it can protrude as much as a predetermined height, there is an advantage of efficiently managing the space occupied by the height guide unit 200.

A fixing member 224 may be further included under the level member 223. The fixing member 224 may be formed in the form of a circular plate with a center through, like the lifting plate 223A.

Then, the fixing member 224 is formed with a thread on the inner circumferential surface of the pierced center can be moved up and down along the outer circumferential surface of the second standing portion (222). For example, the fixing member 224 may be disposed in close contact with the lower portion of the level member 223. The fixed member 224 may prevent the level member 223 from being rotated by an external force such as wind or vibration, thereby causing the height of the level member 223 to fluctuate.

In this embodiment, a gripping portion for easily rotating the fixing member 224 by the operator may be protruded on the outside of the fixing member 224.

Looking at the operation of the reinforcing bar spacer capable of guiding the height of concrete pouring according to the present embodiment configured as described above, the upper reinforcing bar 10 and the lower reinforcing bar 10 are reinforced on the bottom surface of the formwork before concrete is poured at the construction site. You can. At this time, the support unit 100 may support the reinforcing bar 10 in a state spaced apart from the bottom surface to prevent the upper reinforcing bar 10 and the lower reinforcing bar 10 from bending due to a load.

When the support unit 100 is installed below the reinforcing bar 10 reinforced on the bottom surface of the formwork, the height guide unit 200 that guides the pouring height of concrete may be coupled to the support unit 100. When explaining in more detail the process of the height guide unit 200 is coupled to the support unit 100, first, the coupling body portion 210 is moved toward the bottom from the coupling direction, that is, the upper portion of the support body 110, The coupling protrusion 211 formed on the coupling body portion 210 may be fitted into the coupling groove 113 formed on the supporting body portion 110.

For reference, when the engaging projection 211 is fitted into the engaging groove 113, both ends of the engaging body portion 210 are opened toward the outside by a predetermined distance, and when the engaging projection 211 is fitted into the engaging groove 113 Since both ends of the coupling body portion 210 are restored to the original position, the coupling protrusion 211 may be fitted into the coupling groove 113. At this time, since the end of the engaging projection 211 has an inclined surface 212 in the upward direction, the engaging projection 211 can be easily fitted into the engaging groove 113.

In this way, the coupling body portion 210 coupled to the support body portion 110 may be in close contact with the reinforcing bar 10, the upper seating groove 213 formed on the inner upper portion, the upper seating groove 213 and the reinforcing bar 10 Can be magnetically coupled.

Next, the operator can adjust the total height of the height guide unit 220 to the concrete pouring height through the first standing portion 221 and the second standing portion 222. And, the operator can finely adjust the pouring height of concrete once more by raising and lowering the level member 223 along the second standing portion 222 or by adjusting the degree of spreading of the level piece 223B.

The above has been described with reference to one embodiment of the present invention, but those skilled in the art may vary the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
