Description

Reinforcing bar support that can be used in all directions}

The present invention relates to a reinforcing bar support that allows the reinforcing bar to maintain a constant height from the formwork floor when constructing a reinforced concrete building, and in detail, it is possible to support the reinforcing bar in all directions of the reinforced concrete structure, and an efficient product manufacturing process is achieved. It is a technology related to reinforcing bar supports that can be used in all directions that can be lost.

In general, when constructing a building, concrete is used. Although concrete has excellent compressive strength, there is a problem in that its tensile strength is weak. Therefore, the weak tensile strength is reinforced by using reinforced concrete with reinforced reinforced inside the concrete.

The construction of such a building using reinforced concrete can be accomplished by installing a formwork, placing reinforcing bars in the formwork, and then pouring concrete.

At this time, the reinforcing bar installed in the formwork uses a reinforcing bar support so that the height of the reinforcing bar fits the design value before the concrete is poured.

The reinforcing bar support is provided with a reinforcing bar gripping part that firmly grips the reinforcing bar so as not to be separated from the position where the reinforcing bar is installed.

However, the reinforcing bar support provided with the reinforcing bar gripping portion has a problem in that it is difficult to use in response to the thickness of various reinforcing bars.

In order to solve the above problems, Korean Patent Application Laid-Open No. 10-2011-0066271 "reinforcing bar support by improving the reinforcing bar gripping part" is disclosed.

The prior art is composed of a column part (1) and a reinforcing bar gripping part (2; Holder) installed on the upper part of the column part (1), and the reinforcing bar gripping part (2) includes a reinforcing bar mounting part (21) for placing reinforcing bars; Seat) and a reinforcing bar gripping tool (22; arm) that holds the reinforcing bar so that the reinforcing bar does not separate from the reinforcing bar mounting portion (21), the reinforcing bar gripping tool (22) and the large gripping tool (221) It relates to a reinforcing bar support made by improving the reinforcing bar gripping unit, characterized in that it is composed of two gripping holes of a small gripping area 222 installed inside the large breaking area 221, wherein the big breaking area is a large-diameter reinforcing bar. For example, reinforcing bars with a diameter of 12 to 14 mm, and sofa strips with small diameter reinforcing bars, such as 9 to 11 mm in diameter, can be gripped, so that the usable area of the reinforcing bar supports can be greatly expanded, The purpose is to provide great convenience for use.

However, the prior art is easy to grip reinforcing bars of various thicknesses, but since the rebar gripping part is formed only in one direction, there is a problem that the efficiency of work is deteriorated because the worker must find and arrange the rebar gripping part to go upward.

In addition, since the reinforcing bar gripping part is installed only in one direction, when the reinforcing bar gripping part is damaged by an external force, it is difficult to use the reinforcing bar base itself, which causes waste of the reinforcing bar support.

In addition, there is a problem in that the efficiency of the product manufacturing process is degraded because the mold is jammed by the large breaking area 221 and the sofa area 222 during the product manufacturing process for manufacturing the reinforcing bar support. .

Republic of Korea Patent Publication No. 10-2011-0066271 (announcement date 2011.06.17)

Prior to describing the embodiments of the present invention in detail, it should be noted that the embodiments of the present invention are provided to fully describe the present invention to those of ordinary skill in the art.

Accordingly, the claims of the present invention are not limited by the following examples and drawings.

In addition, the drawings in the present specification are intended to allow the description by reference to the drawings to be clearly understood, and thus there is a somewhat exaggerated part. Accordingly, there may be differences between the drawings shown in the present invention and the actual product.

Hereinafter, the present invention will be described with reference to the drawings. However, after an overview of the reinforcing bar support capable of omnidirectional use with reference to FIG. 1A so that the description of the present invention may be concise and clear, the reinforcing bar support capable of omnidirectional use is described with reference to FIGS. 1B to 4B. The components will be described in detail.

1A is a perspective view of a reinforcing bar support capable of omnidirectional use according to an embodiment of the present invention.

The reinforcing bar support 1 capable of omnidirectional use according to an example of the present invention can support the reinforcing bar by being bound with the reinforcing bar to be reinforced in the formwork when constructing a reinforced concrete structure.

In addition, the reinforcing bar support 1 that can be used in all directions is formed in a vertical plate shape in which the binding pieces 33 formed on the third holder 30 are not jammed in the mold frame, thereby reducing the product manufacturing process. It can be done efficiently.

As such, the reinforcing bar support 1 capable of omnidirectional use includes a first mounting portion 10, a second mounting portion 20, and a third mounting portion 30.

Hereinafter, components constituting a reinforcing bar support capable of omnidirectional use will be described in detail with reference to FIGS. 1B to 4B.

The pair of first cradles 10 is a pair of hooks curved downward toward the first concave groove 11 on both sides of the first concave groove 11 and the upper end of the first concave groove 11 It includes a first hook (13).

Reinforcing bars may be bound to the first cradle 10. A first recess 11 having a shape concave downward may be formed in the first cradle 10. The first concave groove 11 may correspond to the shape of the reinforcing bar by being concave downward. Accordingly, the reinforcing bar may be seated and supported in the first groove 11.

First hooks 13 are formed on both sides of the upper end of the first groove 11. The first hook 13 is formed in a hook shape and a pair is formed to face each other.

Accordingly, it is possible to prevent the reinforcing bar seated in the first groove 11 from being gripped by the first hook 13 formed in a hook shape and being separated from the reinforcing bar support (1).

That is, the reinforcing bar may pass through the first hook 13 and be fitted together to be seated in the first groove 11 and bound.

2A to 2C, the first hook 13 according to another embodiment of the present invention is upwardly positioned on both sides of the central portion of the first groove 11, different from the shape of the first hook 13 of the above-described embodiment. It can be formed by a pair of fitting pieces in the shape of a vertical plate.

That is, the first hook 13 in the present embodiment may be formed as a pair of fitting pieces having a long plate shape upward on both sides of the center portion of the first groove 11.

Between a pair of fitting pieces, a reinforcing bar may be bound and held in a force fitting manner. When the reinforcing bar is inserted between a pair of fitting pieces in a force-fitting method, the fitting piece is crushed by a protrusion on the outside of the reinforcing bar, and is integrated with the protrusion of the reinforcing bar, thereby increasing the binding force between the fitting piece and the reinforcing bar. Therefore, it is possible to more effectively prevent the reinforcing bar from flowing, thereby firmly holding the reinforcing bar.

In addition, the fitting piece is formed in a plate shape vertical to the top, so that there is no part where jamming occurs during the product manufacturing process of the reinforcing bar support 1, the process of forcibly separating the finished reinforcing bar support 1 from the mold is performed. Since it does not have to be carried out, the efficiency of the manufacturing process can be increased.

A pair of second cradles 20 are formed between the pair of first cradles 10. That is, the pair of second cradles 20 are coaxial with the first coupling portion and are respectively formed between the pair of first cradles 10.

The second cradle 20 includes a second groove 21 formed to be concave downward and a pair of second hooks 23 formed on both sides of the upper end of the second groove 21.

The reinforcing bar may be bound to the second cradle 20. The second concave groove 21 of the second cradle 20 may be formed to have a shallower depth than the first concave groove 11 of the first cradle 10 described above, and have a wider and wider width and length. Accordingly, a reinforcing bar having a larger diameter and a length than that of the reinforcing bar bound to the first cradle 10 may be relatively bound.

A pair of second hooks 23 may be formed on both sides of the upper end of the second groove 21 of the second cradle 20.

The second hook 23 may be formed in a horizontal plate shape. That is, even if the reinforcing bars having a large diameter are bound together, the second hook 23, which is a horizontal plate having a large area, can easily grip the reinforcing bars having a large diameter. Therefore, it is possible to easily bind reinforcing bars of various sizes by the second hook 23.

In addition, the second hook 23 may have a predetermined elasticity. That is, when the reinforcing bar passes through the second hook 23, the second hook 23 is bent toward the second groove 21 by a predetermined amount due to elasticity, and after the reinforcing bar passes, it can be restored to its original state. Therefore, the reinforcing bar is easily bound to the second cradle 20 and can be firmly gripped at the same time.

3A to 3C, the second hook 23 according to another embodiment of the present invention is larger than the size of the pair of first locking portions 231 and the first locking portions 231 formed in a fan shape. It includes a pair of second locking portions 233 formed small.

The second hook 23 of this embodiment may be formed in a fan shape different from the shape of the second hook 23 of the above-described embodiment. That is, since the first locking portion 231 of the second hook 23 is formed in a fan shape, the lower side of the fan-shaped first locking portion 231 may contact the reinforcing bar. Accordingly, the contact area between the first engaging portion 231 and the reinforcing bar is increased, so that the reinforcing bar is more effectively prevented from flowing, and the reinforcing bar can be firmly gripped.

A second locking part 233 may be formed under the first locking part 231. The second locking part 233 may be formed to be smaller than the size of the first locking part 231.

Accordingly, a reinforcing bar having a size smaller than that of the reinforcing bar gripped by the first engaging portion 231 can also be easily gripped by the second engaging portion 233.

That is, the second hook 23 according to the present embodiment can easily bind and grip reinforcing bars of various sizes, and at the same time, the contact area between the second hook 23 and the reinforcing bars is increased to further grip the reinforcing bars. You can do it easily.

A pair of third cradles 30 may be formed in the vertical direction between the first cradle 10 and the second cradle 20.

The third cradle 30 includes a third concave groove 31 formed downwardly and a binding piece 33 formed below the third groove 31.

Reinforcing bars may be bound to the third cradle 30. The third concave groove 31 of the third cradle 30 may be formed to have the same depth and length as the first concave groove 11 of the first cradle 10 described above, and may have a wide width. Therefore, a reinforcing bar having a relatively larger diameter than the reinforcing bar bound to the first cradle 10 can be bound.

A binding piece 33 may be formed under the third recess 31 of the third cradle 30.

The binding piece 33 may be formed at the corners of the third concave groove 31 and in the four directions. The binding piece 33 may take a protrusion formed on the outside of the deformed reinforcement. Therefore, it is possible to prevent the reinforcing bar from being separated by the binding piece 33.

In addition, the reinforcing bar may be bound and gripped in the binding piece 33 in a force-fitting manner. When the reinforcing bar is inserted between the binding pieces 33 by a force-fitting method, the binding pieces are crushed by a protrusion on the outside of the reinforcing bar, and are integrated with the protrusion of the reinforcing bar, thereby increasing the binding force between the binding pieces 33 and the reinforcing bar. Therefore, it is possible to more effectively prevent the reinforcing bar from flowing, thereby firmly holding the reinforcing bar.

The third cradle 30 is different from the first cradle 10 and the second cradle 20 described above by forming a binding piece 33 on the lower side of the third concave groove 31, thereby forming a third concave groove 31. The upper side of the can be formed to be open. Accordingly, since the upper side of the third recess 31 is opened and formed, reinforcing bars having a larger diameter that cannot be bound to the first cradle 10 and the second cradle 20 can be easily bound.

The binding piece 33 may be formed in a plate shape perpendicular to the length direction. Therefore, there is no part where the mold used during the manufacturing process of the reinforcing bar support 1 is jammed, so that the operator does not have to perform the process of forcibly separating the finished reinforcing bar support 1 from the mold. Efficiency can be increased.

In other words, the image side mold and the lower side mold when fabricating a reinforced base (1) in the top-bottom mold which is formed by the vertical reciprocating movement is carried out toward the top and bottom will produce a reinforced base (1). At this time, if the upper mold is jammed when the upper mold and the lower mold are separated, the reinforcing bar support (1) is lifted up with the upper mold, and for the subsequent manufacturing process, the reinforcing bar support (1) is forcibly separated from the upper mold. The process of doing must be done. Therefore, there is a problem in that the product manufacturing process cannot be efficiently performed due to the addition of unnecessary process steps in the product manufacturing process, thereby delaying manufacturing.

Therefore, by forming the reinforcing bar separation prevention configuration formed in the first and third mounting portions 10 in a shape that does not cause jamming in the mold, the reinforcing bar support 1 is caught in the upper mold in the manufacturing process. As it does not occur, the separation process may be omitted, thereby increasing the efficiency and economic efficiency of product manufacturing.

Referring to Figures 4a to 4c, in another embodiment of the present invention, the first hook 13 is formed as a locking piece in the shape of a plate perpendicular to the upper side, and the second hook 23 is a pair of a fan shape. It may be formed of a pair of second locking portions 233 that are formed smaller than the size of the first locking portion 231 and the first locking portion 231.

Accordingly, since the reinforcing bar support 1 is not jammed in the upper mold in the product manufacturing process, the separation process is omitted, thereby increasing the efficiency and economic efficiency of product manufacturing.

In addition, a through hole 35 having a circular shape may be formed in the middle of the third recess 31 of the third cradle 30. The through hole 35 may allow concrete to flow into the inside of the reinforcing bar support (1). Therefore, when concrete is poured, the concrete flows into the through hole 35, so that the concrete, the reinforcing bar, and the reinforcing bar support 1 can be integrated.

In addition, since the gas generated by the hardening action of concrete can be discharged to the outside, the hardening action of concrete is made easier, thereby preventing loss of strength of the concrete.

Embodiments of the present invention have been described above with reference to the accompanying drawings, but those of ordinary skill in the art to which the present invention pertains can be implemented in other specific forms without changing the technical spirit or essential features. You will be able to understand. Therefore, it is to be understood that the embodiments described above are illustrative and non-limiting in all respects.
