The present invention relates to a spacer for opening the panel and the gap between the panel or the panel and the corner connector (inconor or outconor),

In particular, the present invention relates to a spacer for a formwork panel for preventing leakage of the placed concrete by providing an elastic means or a packing part further provided with a fine protrusion at a contact portion of the panel, in particular, a Euroform panel or a corner connector. will be.

Building formwork panels are designed to facilitate the assembly and dismantling of recent formwork from early veneer plywood panels, and are a number of improvements represented by Euroform (see Publication of Utility Model Registration No.0205912 (2000.09.27) `` Formwork Side Panels ''). Various kinds of things are known to the panel,

In terms of materials, it is diversified to wood, which is represented by veneer plywood, and special synthetic resin such as FRP, steel or alloy materials.

The direction of change of the form panel is to shed light on the tendency of the high-rise building and the building trend of the large-scale assembly or high-rise buildings represented by the apartment.

Most of the formwork panels used in building structures are ready-made products with a certain width and height, and the length of the building is not directly proportional to the width of the ready-made panels, so the construction work already uses spacers to increase the gap between the panels.

In particular, in the multi-story building, the retaining wall structure of the underground is often used for underground retaining wall because it is often different from the ground structure.

Techniques related to conventional spacers

Patent Registration No. 0370437 (2003.01.17) 『Euroform Formation Spacer』 related to spacer having adhesion protrusion in close contact with inner surface of both sides of Euroform formwork of Dongyoung Metal Co., Ltd.

Utility Model Registration No. 2098106 (2002.11.30), `` Spacer Assembly Filling Panel Between Formwork, '' Utility Model Registration No. 0298107 (2002.11. 30) "Spacer Assembly to Fill Between Panels of Formwork" and Patent Publication 2002-0080307 (20002.10.23) "Spacer Assembly to Fill Between Panels of Formwork".

However, such a conventional formwork panel spacer alone is not enough to prevent the concrete from leaking between the formwork panels, especially when the surface remains uneven because the concrete is hardened on the side frame member by repeated use of the formwork panels. Leakage problems can be even worse.

The present invention is proposed to solve the concrete leakage problem more completely by improving the spacer for the conventional formwork panel.

Accordingly, an object of the present invention is to provide a spacer having a plurality of fine protrusions continuously formed in the vertical direction in the contact portion with the formwork panel or the corner connector.

In addition, an object of the present invention is to provide a spacer having a further improved adhesion by further introducing an elastic means arranged in the contact portion and / or a packing portion formed in the vertical direction in contact with the inner surface of each protrusion of the panel.

Furthermore, an object of the present invention is to provide a spacer produced using waste synthetic resin.

In order to achieve the above object, the formwork panel spacer according to the present invention is sandwiched between a panel and a panel made of a contact plate and a frame member provided at the rear of the contact plate and having protrusions at front and rear ends, respectively. Front and rear end contact portion is formed in a continuous continuous fine projection in contact with the protrusion of the panel; And a connection part connecting the contact parts.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In each of the drawings, the same reference numerals, in particular, the tens and ones digits, or the tens, ones and alphabets, refer to members having the same function, and unless otherwise specified, each reference is referred to. What is necessary is just to consider the member which conforms to these standards.

In addition, in describing the formwork panel spacer 10 according to the present invention, the direction reference is specified with reference to FIG. 1A.

The inconor part side of the wall W is to the front, and the opposite side to the rear,

The upper and lower parts are divided by assuming that the shape shown corresponds to the direction of gravity,

The space between the front and rear contact portions 11A and 11B of the spacer 10 is inward, and the contact portion is determined outward.

First, as shown in FIGS. 1A and 1B, the illustrated spacer 10 has two contact portions 11A and 11B at front and rear ends, and a connecting portion 13 connecting the two contact portions, and fine protrusions on the side of the contact portion. 11a is formed, and the packing part 12 is further formed in the inner four corners of the said contact part 11A and 11B compared with the concept of Claim 1. As shown in FIG.

The illustrated formwork panel 20 illustrates a general euroform, which is provided with a rim member 23 around the rear circumference of the contact plate 21 contacting the concrete of the wall W from the front surface.

The upper and lower portions of the frame member 23 are omitted so that the reinforcing plate 25 provided on the rear surface of the contact plate 21 of the panel 20 can be more surely confirmed.

The spacer 10 according to the invention can be arranged between the panel and the panel or between the panel and the inconor or out-conner end connector.

In the figure is shown a form arranged between the inner connector 30 is located inside the corner portion to form the corner of the panel 20 and the wall (W).

The corner connector 30 also has a contact plate 31 which abuts against the wall W, a frame member 33 provided around the contact plate, and a reinforcing plate 35. The upper and lower members are omitted.

A plurality of fastening holes 23A and 33A for fastening the panel and the connector to each other are formed in the edge members 23 and 33 of the panel 20 and the inner connector 30 at regular intervals.

The member inserted into the fastening hole of the panel and the connector to bind the two members is known a number of types,

The illustrated form includes a fastening rod 41 inserted into the fastening holes 23A and 33A of the panel and the connector, and inserted into the insertion holes 41a provided on both sides of the fastening rod, so that the edge member of the panel and the inner connector ( 23) 33 is made of a fastening pin 43 in contact with the inner surface, the fastening pin 43 is caught around the insertion hole of the fastening rod 41 due to the head (43a).

In addition, there are various known members for binding the panel or corner connector located inside the wall W and the panel or corner connector located outside.

The illustrated form is a tie rod 45, and the insertion hole 45a is formed on both sides of the tie rod so that the fastening pin can be inserted.

As shown in the drawing, the edge members 23 and 33 of the panel 20 and the inner connector 30 have front and rear end protrusions 23a and 23b and 33a and 33b formed in the vertical direction.

The protrusion has a plurality of insertion portions 23B and 33B for insertion of the tie rod 45 at regular intervals up and down.

In describing the spacer 10 according to the present invention, in the description and the claims, in the expression that the contact portions 11A and 11B contact the protrusions 23a and 23b of the panel 20, 'panel' It refers to both a literal panel and a corner connector.

The connecting portion 13 of the spacer 10 is formed with a plurality of fastening holes 13A arranged up and down at a predetermined interval to insert the fastening rod 41 described above,

The spacing between the connector fastening holes 13A of the spacer 10 is the spacing between the fastening holes 23A and 33A of the edge members 23 and 33 of the panel 20 and the inner connector 30. Equal to or

 The spacing between the fasteners of either member may be wider (e.g. when the spacers have a spacing of 5 cm, the spacing of the panels is an integer multiple of one another, such as 10 cm),

In addition, as described in Utility Model Registration No. 2098106 by the applicant of the present invention, a set of fastening holes of spacers arranged on the same vertical surface up and down may be two sets (or three or more sets) arranged on different vertical surfaces.

The spacer 10 shown in FIG. 1A is inserted into the tie rod 45 formed in the protrusions 23a, 23b, 33a, 33b of the edge members 23 and 33 of the panel 20 and the inner connector 30. A groove corresponding to the portions 23B and 33B is not formed in the packing portion 12.

This is to consider that the material forming the spacer 10 is soft, so that the packing portion 12 is pushed to ensure the insertion of the tie rod when the tie rod 45 is inserted,

Due to the soft packing part, a gap that may occur between the tie rod and the insertion part is filled, and thus the problem of concrete leaking through the insertion parts 23b and 33b for the tie rod 45 can be more surely prevented.

As such, the spacer may be a whole synthetic resin, particularly a synthetic resin in which waste materials are recycled, and only the packing part may be made of a soft material separately.

On the other hand, the spacer 10 shown in FIG. 2 is different in that a plurality of tie rod inserting parts 112A and 112B are formed at regular intervals in the packing part 12 in the vertical direction. 110 may be made of a relatively hard material.

1A and 1B, the spacer 10 according to the present invention has a plurality of fine protrusions 11a formed in the vertical direction in the contact portions 11A and 11B.

Even if the concrete is not smooth due to sticking to the protrusions 23a, 23b (33a, 33b) of the panel or the corner connector, the adhesion between the spacer and the panel can be improved, so that the mutual adhesion can be reliably leaked during the concrete pouring. Prevent,

In addition, the packing part 12 provided at the four inner corners of the contact parts 11A and 11B is in close contact with the protrusions 23a, 23b, 33a, 33b of the panel and the inner connector, thereby preventing the leakage of concrete. As a result, construction of a concrete structure with higher maturity becomes possible.

The spacer 10 shown in FIG. 2 is in addition to the tie rod 45 inserting portions 112A and 112B described above compared to the spacer shown in FIG. 1A, as can be more reliably identified in FIG. 3A. Since the plurality of fine protrusions 112a are also formed in the vertical direction outside the packing part 112, it is possible to improve the adhesiveness with the panel and the like.
If the spacer is flat without the fine protrusions, and the contact surface of the panel is minutely bumpy or concretely crusted, and is noticeably bumpy, the gap between the panel and the spacer is continuously formed in the entirety. Compared to the leakage of concrete
As shown in FIGS. 1A and 2, in the case of a spacer having fine protrusions 11a and 112a formed in the contact portion and the packing portion, an uneven portion of the panel is located in the gap between the fine protrusion and the fine protrusion, or any one of the spacers is provided. Even if the micro protrusions of the panel come into contact with the protrusions of the panel to open the gap, the other micro protrusions come into contact with the flat surface of the panel, thereby limiting the occurrence of continuous gaps.
The effect of suppressing the occurrence of a continuous gap such that concrete leaks to the contact surface between the spacer and the panel due to such fine protrusions is greater when the spacer of the soft material.

Next, variously modified spacers of the present invention will be described with reference to FIGS. 3 and 4.

Spacers shown in (b) to (bar) of FIG. 3 basically introduce a first elastic means for imparting elasticity to the contact portion to further improve adhesiveness upon contact with the panel or the like.

First, the first elastic means embodied in the spacer 210 of (b) is formed in a shape corresponding to the outer shape of the contact portion in the vertical direction in order to give elasticity to the contact portions 11A and 11B. It consists of elastic holes 17, which are holes, and fine projections are formed on both sides of each contact portion,

These elastic holes 17 also help to reduce the material required for spacers,

Considerations for such material savings include forming the gap S (see FIG. 1B) with the edge members 23 and 33 of the panel and the inner connector at the spacers shown in FIGS. 1B and 3A. It is also applied to the form of the connecting portion 13, 113.

The first elastic means embodied in the spacer 310 shown in (c) of FIG. 3 is continuously formed along the periphery of the contact portions 211A and 211B, and has an end portion separated from the connecting portion 213 to be separated. Consisting of a piece (215),

Since the contact portion as well as the packing portion are formed by the outer shape formed by the elastic piece, it is possible to impart elasticity to the packing portion, so that it can be referred to as a second elastic means different from the first elastic means for the contact portion (that is, the continuous elastic piece is the contact portion And simultaneously implementing the first and second elastic means for the packing part) also have fine protrusions.

The elastic piece of the spacer 410 shown in (d) is different from the elastic piece of (c) in which the contact area extension portion 215b formed at the end is bent.

Due to the contact area expansion part 215b, when the elastic piece 214 is pressed when the panel and / or the corner connector are fastened, the elastic piece end and the connection part 213 can be more stably supported.

In addition, the spacer 410 of (d) has a cutout portion 215a formed continuously in the vertical direction at each bent portion of the elastic piece 215, so that deformation of the elastic piece due to pressure is more easily performed ( Different from the spacer 310 of

Here, the bent part “Mada” is the concept of expressing the bent part “all” or the necessary “part” together.

Subsequently, in the spacer 510 illustrated in FIG. 3E, the minute protrusions 311a are formed in common as compared with those of FIG. 1A, but the packing part is omitted.

For this reason, although the shape of the contact parts 311A and 311B is different, the shape of the connection part 313 is the same,

The first elastic means implemented is also in the form of an elastic hole (317A), in particular a half-moon-shaped elastic hole, both sides of the contact portion (311A) (3121B) in which the fine projection (311a) is formed protrude in a round shape,

Both sides of the soft contact portion may be flattened by the pressurization by the edge member protrusion 23a of the formwork panel 20, and the elastic hole 317A may be filled so that only the contour remains.

In addition, the spacer 610 shown in (bar) has a central hole 317B in addition to the half-moon-shaped elastic hole 317A, which contributes to elastic reinforcement and material saving.

Next, the spacers shown in FIG. 4 are further provided with a second elastic means for providing elasticity to the packing part to improve adhesion and to facilitate separation of the panel and the spacer during form dismantling after concrete curing.

First, the spacer 710A of (a) has a second elastic means 412A formed by cutting in the vertical direction at four corners of the inner axial surface of the packing part 412.

The spacer 710B of (B) is different from that of (A) in that an elastic hole 417 (which corresponds to the first elastic means) formed in a shape corresponding to the outer shape of the contact portion is different.

The spacer 810A of (c) has a different shape of the connecting portion 513 than the spacer of (a),

The spacer 810B of (D) has a cutout portion 512B connected to the second elastic means 512A at the connection portion of the packing portion 512 and the contact portion, as compared to the spacer of (C). The difference is that the deformation is made easier,

The spacer 910 (e) has a form of the second elastic means 612A penetrated in the form of a hole when viewed from the cross section of the packing portion 612.

As described above, the formwork panel spacer according to the present invention has a plurality of fine protrusions formed continuously in a vertical direction at a contact portion with a formwork panel or a corner connector, and the elastic means arranged at the contact portion and / or the panel The packing part formed in the vertical direction to be in contact with the inner surface of each protrusion was further introduced to further improve the adhesiveness. Furthermore, the present invention can provide a spacer manufactured using waste synthetic resin, and the spacer according to the present invention. It is possible to apply a well-known coating agent on the outer peripheral surface of the spacer so that it is easily separated from the hardened concrete and to form a smoother concrete structure.

In the above description of the present invention with reference to the accompanying drawings with reference to the accompanying drawings having a specific shape and structure, the present invention can be various combinations and modifications by those skilled in the art, such combinations and changes are within the protection scope of the invention Should be interpreted as belonging.
