A plurality of tightening holes 18 may be formed in the tightening position of the binding member to strengthen the binding strength of the knitting body.

One of the bodies is provided with the first inner circumferential surface and the second inner circumferential surface 13, 14 and the fastening hole 18, and are seated by facing each other around the radius of the reinforcing bar to form a pair of the first body and the second body 10. The inner circumferential surface of 11) forms a structure opposite to each other.

Accordingly, since the first and second bodies 10 and 11 face each other and are seated on the reinforcing bars, the first and second inner circumferential surfaces of the first body 30 and the first and second inner circumferential surfaces of the second body 40 are disposed. The hollow spaces are formed at the intervals facing each other, and the rebars are seated in the spaces, but the rebars may be seated in any one space, or two rebars may be seated in the parallel space.

That is, a first piece and a second piece 10 and 11 are provided to face each other, but are composed of independent components without being mutually restrained between the pieces. It can be seated on.

Preferably, the first inner circumferential surface and the second inner circumferential surface 13 and 14 may be freely seated without being constrained to the up, down, left, and right mounting directions by having the same inner diameter. This increases the efficiency of work because there is no need to install in the up and down, left and right directions during the site construction.

In order to reinforce the supporting structure, the hypothetical formwork member is supported by surrounding the formwork member through a steel member, which is a pipe, or supported by a shoring, so as not to be spaced apart or conducted by lateral pressure and lateral pressure generated during concrete placing. Since the supporting structure does not provide a structure that is integrated with the reinforcing bars, the raised form is spaced or inverted, causing the surface of the cured concrete to be discontinuous or displaced, resulting in increased costs due to reconstruction and the inability to precisely construct the concrete structure. Can follow.

In order to provide a structure for binding the reinforcing bar and the formwork member, the tie member fixed to the formwork member and the reinforced reinforcing bar are integrated to prevent the risk that the formwork member is spaced apart or fell during concrete placement. do.

In other words, in order to prevent the separation of the formwork member when placing concrete, by providing a structure in which the formwork member is supported and fixed by binding the tie member fixed to the formwork member to the reinforcing bar, the support structure is bound to the formwork member from the reinforcing bar, Furthermore, the structure is fixed to the formwork member at both ends of the reinforcement by binding to the formwork member from the rebar.

This is a binding structure in which one side tie member and the other tie member, which form a structure that is sequentially fixed and fixed, are fastened to the reinforcing bar to prevent spacing of the form member, and thus the reinforced steel is used as a tie member to prevent the spacing of the form member. It becomes a structure.

As a result, the lengthwise direction of the reinforcing bars and the length direction of the tie members may be maintained in a straight line and may be fastened to maintain the alignment of the reinforcing bars arranged as an integrated structure of the reinforcing bars and the tie members.

Therefore, it is possible to efficiently receive the transverse pressure and side pressure transmitted from the unhardened concrete to the reinforcing bar and fix the form member to the reinforcing bar so as not to be spaced apart or conducted by the side pressure when placing concrete.

Therefore, the material cost can be reduced by omitting steel members or pipes that support the respective formwork members, and steel pipes or pipes that are supported by oblique lines, and the reinforcing bars 480 need to be overlapped using a binding line. Since there is no need, the efficiency of the process becomes possible.

In addition, the structure of the overlapped joint through a general binding line is easy to occur the separation or separation of the reinforcement by the external force may cause defects in the quality of the concrete itself, but the overlapping joint through the mold spacing prevention binder of the present invention is more secure joint The formwork gap preventing fastener of the present invention is to be embedded in the concrete to be permanently embedded to form a concrete foundation with the tie member 440, thereby improving the dimensional quality of the cured concrete after embedding.

In addition, as a function of fastening the reinforcing bar 480 and the flat tie as described above and the function of fastening the reinforcing bar 480 and the overlapped bridge reinforcing bars are integrally provided, the workability can be freely provided in a desired position, thereby increasing the workability. .

Although not shown, the first inner circumferential surface and the second inner circumferential surface 13 and 14 may be formed to have curvatures of different inner diameters so as to overlap the bars of different outer diameters. That is, when any one of the reinforcing bar is accommodated on the first inner peripheral surface and the reinforcing bars having different specifications from the reinforcing bar should be overlapped, if the inner diameter curvature of the second inner peripheral surface is the same as the first inner peripheral surface, the reinforcing bars cannot be accommodated. Therefore, it can be formed into a piece having a different inner diameter for the overlapping joint.

Referring to FIG. 2, the first and second bodies 10 and 11 are in contact with one side inner circumferential surface 22 of the tip portion 16 where the curvature formed by the first inner circumferential surface or the second inner circumferential surface 21 and 22 ends. ) Is extended and the front end portion 21 in contact with the other inner peripheral surface is shortened so that each extended front end portion 22 is in close contact with each other when the first and second pieces 10 and 11 are seated in the radius of the reinforcing bar 20. Can be.

That is, when the inner circumferential surfaces of the first and second pieces 10 and 11 face each other, two hollow spaces are formed side by side at opposite intervals, and the reinforcing bars 20 are seated in the space, and the tie member and the reinforcing bar 20 are disposed. In the binding structure of the liver, the rebar 20 is seated only in the hollow space on any one side.

In the binding structure of the reinforcing bar 20 and the reinforcing bar 20, the rebar 20 should be seated in both hollow spaces. However, in the binding structure between the tie member and the reinforcing bar 20, the rebar 20 only in the hollow space on either side. ) Is preferably settled.

In other words, in order to fasten the tie member fixed from the formwork member to the reinforcing bar 20, the formwork space preventing binding device of the present invention is preferably fastened to a structure in which the rebar 20 is seated only in any one of the hollow spaces. Do. That is, two hollow spaces formed by the opposite seated first inner circumferential surfaces and the second inner circumferential surfaces 13 and 14 are formed, but the reinforcing bars 20 are reinforced even when the reinforcing bars 20 are seated in only one of the hollow spaces. It is possible to secure and deliver sufficient bearing capacity. Nevertheless, the reinforcing bar 20 and the reinforcing bar 20 are jointed by utilizing the reinforcing bar 20 as an intermediate fastening member only when the end of the tie member and the end of the reinforcing bar 20 are not aligned in line. In order to provide a structure in which a plurality of inner circumferential surfaces are formed to seat other reinforcing bars 20 in a hollow space, first and second inner circumferential surfaces 13 and 14 are provided.

In other words, when the distal end portion within the two-quarter radius range of the outer periphery of the reinforcing bar 20 of the first and second pieces 10 and 11 faces or is shortened of the first and second pieces 10 and 11. When the front end portion 21 and the extended front end portion 22 face each other, when the rebar 20 is seated only in the hollow space on either side, the rebar 20 is seated in the process of pressing the formwork preventing prevention fastener of the present invention. In the hollow space, the tip is not in close contact, and the first and second pieces 10 and 11 are deformed to be in close contact with each other so as to be inclined to one side. Therefore, there is a risk that the formwork gap preventing fastener of the present invention is plastically deformed or bound tie member is deviated.

Accordingly, when the reinforced reinforcement 20 and the bridge reinforcement should be provided with a structure in which overlapping joints are formed by the formwork gap preventing fastener of the present invention, the front end portion in contact with the hollow space in which the reinforcement 20 is seated is shortened at the distal end portion 21. ) Is not in close contact with each other so as to face each other and the front end is in contact with the hollow space where the reinforcing bar 20 is not seated so that the extended front end 22 is in close contact with each other.

Thus, in providing the structure to be bound, the hollow space in which the rebar 20 is seated when the knitted bodies are mutually compressed becomes a structure supported by the reinforcing bar 20 and the hollow space in which the reinforcing bar 20 is not seated. The extended tip portion 22 is in close contact with each other to be a structure that is supported.

The support structure of the first piece and the second piece (10, 11) has the same shape, and when one end portion 22 is extended and the other end portion 21 is reduced in the mounting direction of any one side piece In other words, when the positions of the first inner circumferential surface and the second inner circumferential surface 13 and 14 are changed, the extended tip portion 22 is in close contact with each other, and the positions of the first inner circumferential surface and the second inner circumferential surface 13 and 14 are maintained. When the replacement is performed again, the extended tip portion 22 and the shortened tip portion 21 face each other.

Preferably, when the mounting direction of the knitting body is implemented in such a structure that the extended front end portions 22 are in close contact with each other, the reinforcing bar 20 is not seated in the hollow space where the extended front end portions 22 contact with the shortened front end portion 21. Reinforcing bar 20 is seated in the hollow space in contact with). As a result, even though there is a hollow space in which the rebar 20 is not seated, a binding fixing structure of the tie member and the rebar 20 may be achieved.

Preferably, the rebar 20 is seated in both of the hollow spaces when the mounting direction of the knitting body is implemented in a structure in which the extended tip portion 22 and the shortened tip portion 21 face each other. As a result, the first piece and the second piece 10 and 11 seated on the reinforcing bar 20 may be bonded to each other by pressing the reinforcing bars 20 by the distance of each tip portion, thereby enabling a more tight binding fixation.

As a result, the inner circumferential surfaces of the first and second pieces 10 and 11 are opposed to each other, but the mounting can be freely inverted in consideration of the front end to be opposed since the mounting can be reversed 180 degrees on a plane formed by the free end of the seating direction. have.

In this way, it is possible to apply and implement the binding structure of the tie member and the reinforced reinforcing bar 20 fixed from the formwork member only in a variety of situations with only the formwork gap preventing fastener of the present invention as a single shape.

A fastening hole 18 is formed for accommodating the first member and the second member 10 and 11 for the binding member to be inserted therethrough, the width and the height of which can accommodate the binding member and the binding member. It consists of a shape which accommodates the cross-sectional shape of a member.

The keyhole shape is a keyhole shape in which polygons and rectangles are combined, or a keyhole shape in which polygons and rectangles are combined and square bidirectional, coincides with the centers of polygons and rectangles, or may be symmetrical vertically or horizontally, and a cross section is rectangular or polygonal. The desired member can be freely selected from among the members, so that the binding member having a rectangular or polygonal cross section can be used in common with one tightening hole.

Alternatively, the keyhole shape may be a keyhole shape in which a circle and a rectangle are combined, or a keyhole shape in a quadrangular direction. The center of the circle and the rectangle may be coincident or vertically or horizontally symmetrically formed. The member is made selectable so that a single fastening hole 18 can be used for a joint member having a rectangular or circular cross section.

DETAILED DESCRIPTION Hereinafter, various embodiments of the formwork gap preventing fastener according to the present invention will be described with reference to the accompanying drawings.

First, referring to FIGS. 8 and 9, the tie member may be formed as a flat tie 210 for a flow form fixed from a formwork member that is a flow form according to an embodiment.

The binding member is interposed through a rectangular pin hole 202 provided at the end of the flow-form flat tie 210, the parallel surface in the end direction of the flow-type flat tie 210 is the first piece or the second piece It is in close contact with the outer circumferential surface of the 230 and 231 is fixed.

When the tie member is a flat tie 210 for the euroform fixed from the formwork member, which is a euroform, the binding member may be formed of a wedge pin 200 or an extended wedge pin through the tie member.

The wedge pin 200 has a locking piece 202 is formed at one side end and an inclined surface 203 is formed narrower toward the end at the other end and a coupling hole 201 is formed at the center of the body to which the fixing member is coupled. .

The coupling hole 201 is formed in a direction orthogonal to a longitudinal direction through which the binding member penetrates into the tightening hole. Therefore, as the coupling hole 201 is formed orthogonal to the longitudinal direction of the binding member, the fixing member coupled to the coupling hole 201 is also coupled orthogonally to the longitudinal direction of the wedge pin or the extended wedge pin as the binding member. It is fixed.

 Furthermore, the one end and the other end are extended so that the length of the waist portion extends in the longitudinal direction according to the insertion depth to be engaged so that the coupling hole 201 can be drawn out from the tightening holes of the first and second pieces after penetration. It may consist of wedge pins.

That is, the coupling hole 201 should be formed to be spaced apart from the end formed by the engaging piece of the wedge pin, which is the binding member, by a distance that can compress and tighten the knitted body, and the coupling hole 201 is formed in the first and second pieces. For example, the distance drawn from the tightening hole of the end of the fixing member may be easily entered in the separation distance where the coupling hole is completely exposed from two branches 1 of the cross section of the coupling hole so that the knitted body may be compressed by the fixing member inserted completely. The separation distance of the coupling hole 201 should include a width in which the one piece and the second piece 10, 11 including the width of the reinforcing bar 20 are opposed to each other. Therefore, the distance that the coupling hole 201 is spaced apart depends on the width of the rebar 20 to be seated and the width specifications of the first and second pieces.

Accordingly, by using the wedge pin used for the construction of the formwork member, the wedge pin of the construction site can be used as the binding member without the need for the binding member separately, thereby facilitating the material management at the construction site. .

The engaging piece 202 of the wedge pin 200 is engaged with the tightening hole 240 and the coupling hole 201 of the wedge pin penetrates through the first and second pieces 230 and 231 so that the first piece and The fixing member is coupled to the exposed coupling hole 201 withdrawn from the tightening hole 240 of the second piece.

When the wedge pin is formed or extending in the longitudinal direction and the coupling hole formed in the direction orthogonal to the longitudinal direction penetrating into the tightening hole is made of an extended wedge pin formed to be drawn out from the tightening holes of the first piece and the second piece, The fixing member fixed to the binding member is perpendicular to the lengthwise direction of the wedge pin or the elongated wedge pin, which is the binding member, to the coupling hole 201 of the wedge pin, which is the binding member protruding from the tightening hole 240. It may be made of a wedge pin 220 is wedge in the direction.

The fixing member wedge pin 220 is narrow in width from one end to the other end so as to wedge into the coupling hole 201 to form a wedge shape. As the wedge-shaped fixing member is wedged into the coupling hole 201 and is hit, a wedge action is generated from a force of a horizontal component orthogonal to the hitting direction so that the locking piece 202 of the binding member is supported on one side. On the other side, the inclined surface 203 of the wedge-shaped member is supported by the coupling hole 201 and the contact point in close contact with the first or second piece 230 and 231 positioned on the other side of the wedge-shaped member is gradually tightened. As the load, the first piece and the second piece 230 and 231 are pressed more firmly or plastically deformed by the wedge action, so that the space between the reinforcing bar 250 and the first piece and the second piece 230 and 231 is separated. It is gradually reduced and the reinforcing bar is sandwiched between the inner circumferential surfaces of the first and second knitted fabrics 230 and 231.

By using the wedge pin used in the construction of the formwork member, the wedge pin of the construction site can be used as a fixing member without the need for a separate fixing member, thereby making it convenient for material management at the construction site.

Preferably, the inclined surface 203 of the wedge pin that is the fixing member may be formed with a top portion 260 to prevent the wedge after being pinched. The cross-sectional shape of the saw portion 260 may form any one selected from triangular, circular, oval.
