In addition, an object of the present invention is to provide a formwork panel to the angle formed between the exposed surface of the strip and the body is an acute angle to thereby further improve the completeness of the chamfering surface.

Lastly, the present invention further provides a formwork panel, which is formed on both sides of the strip by extension to the body and is fastened to another panel by using a conventional fastening pin, so as to function as a direct panel without using a separate support plate. For the purpose of

In order to achieve the above object, the present invention provides a body having a shape and size corresponding to the shape and size of a protruding surface of a concrete formed body such as a column, a wall, or a beam, and one end of the protruding surface of the formed body on the upper surface of the body. Or arranged at both ends to enable chamfering of the edge of the molded body, and having a molded contact surface, the body engaging surface, and an exposed surface, the strip having a triangular outer shape of a cross section having a triangular shape, The technical subject matter is that the soft part was introduce | transduced into the attachment part formed by the engagement surface.

In addition, the present invention in the body is an extension portion is further formed on the side of the strip and the extension portion is a support piece for the other formwork panel is protruding, the support piece is a technical point that the soft portion (軟 質 部) is introduced.

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 digits, refer to the same functional members, and unless otherwise specified, refer to each reference. What is necessary is just to consider a member as a member based on these standards. In addition, in relation to the soft portion to be described below, the soft portion is expressed in diagonal lines unlike the other portions for the convenience of understanding the soft portion such as to make it easy to visually distinguish, but this is for convenience of explanation and understanding. Note that the soft part in the real product is not shaped to always be visually different from the other parts of the product.

In describing the formwork panel according to the present invention, the direction reference is specified with reference to FIGS. 1 and 5.

Considering the case where the formwork panel P of one aspect according to the present invention is used for forming a joist J of a building, the upper surface 10a is provided on the side of the body 10 on which the strip 13 protrudes. ), And the opposite side is set as the lower surface (10b), and the two extending portions (11A) (11B) side to the side with the strip (13) located at the top as viewed from the front.

First, in FIG. 1A, the chamfer formwork panel P includes a body 10 having a shape and size corresponding to the shape and size of a protruding surface of a concrete molded body such as a column, a wall, or a beam, and the body 10. It is formed on the upper surface 10a of the upper and lower ends 10a, and is arranged on both ends of the projecting surface side of the desired molded body, and consists of two strips 13 to enable chamfering of the molded object edges.

The body 10 has a shape and size corresponding to the shape and size of the concrete molded body,

When the length of the body is the same as the entire length of the molded body or when dividing the length of the molded body means that it has a length corresponding to the length of the divided molded body,

The width of the body means that the distance between the ends (13d) of the two strips 13 is a dimension capable of maintaining the form that is equal to the width of the molded body,

Furthermore, it is usually meant that the body will have a flat shape, but depending on the design of the building part to be molded, a groove for intaglio or embossment may be formed, or it may have a curved or angular shape rather than a flat plate.

The strip 13 has a principal outline of a cross section that is approximately triangular,

As shown in FIGS. 1A and 5, three surfaces of the strip 13 are contact surfaces 13a contacting the beam J, which is a molded body, a coupling surface 13b connected to the upper surface 10a of the body 10, and The exposed surface 13c, which is a part of the side facing the other panel 23, and the end portion 13d corresponding to the vertex in cross section is assembled with the other panel in the form of contact with the side panel 23. Here, the upper end of the portion consisting of the contact surface 13a and the exposed surface 13c of the strip 13 is formed with an attachment 13e including an end portion 13d, and the attachment 13e. ) Is molded from a material having soft properties. That is, the soft part 13A is introduced.

In general, after the completion of one operation, the mold panel is re-molded to use it again, and the deformation degree of the strip 13 of the panel, which is a more frequent and sensitive part than the panel body 10, is more severe. This is even more true of the attachment 13e formed of the contact surface 13a and the exposed surface 13c among the strip 13 portions. For this reason, the soft portion 13A is introduced into the attachment 13e of the strip 13, and the deformed attachment 13e can be easily removed and removed after the completion of one operation due to the characteristics of the soft portion. After remolding and attaching only this part to complete the panel, the panel for chamfering which can be used for the next work can be easily reshaped.

In addition, it is possible to increase the completeness of the chamfered surface by making the attachment 13e of the strip 13 soft. That is, as shown in Figure 2 for the molding of the concrete molded body (F) on both sides of the panel (P) according to the present invention to position the side panel 23 and fastening means for each panel (P) 23, In particular, if the fixing using the fastening pins 25,

The space is formed by the assembled formwork panel (P) (23),

The concrete for the molded body (F) is injected into the space.

At this time, due to the load of the concrete, the attachment 13e composed of the soft is pushed to the left, and the angle between the molded body contact surface 13a of the strip and the upper surface 10a of the body is increased (θ '→ θ). '').

That is, when a load of concrete is applied, the attachment 13e composed of soft materials is pushed to the left side, and the exposed surface 13c side of the end 13d of the strip 13 has a possible length with the side panel 23. Line contact or surface contact over the whole direction

As a result, the adhesion to the side panel 23 is increased, so that concrete penetrates toward the exposed surface 13c, thereby preventing the chamfered surface of the molded body F from being smooth and uneven, which prevents the completion of the finish.

In addition, as shown in FIG. 1B, the soft portion 13A further includes a protrusion 13B in the direction of the exposed surface of the strip, which protrudes in the direction of the exposed surface of the strip to which the other formwork panel is coupled. This is because, by forming the soft portion, the adhesion to the other formwork panel is excellent due to the property of the soft material. Reference numeral 15, which is not described, is a support piece protruding for another formwork panel, and the other panel is inserted into a space formed between the support piece 15 and the strip 13 and fixed to the body 10.

Next, in order to increase the degree of completeness of the chamfering surface, an angle θ formed between the exposed surface 13c of the strip 10 and the upper surface 10a of the body 10 as shown in FIGS. 1 and 2. Considering an acute angle

That is, by setting the angle θ formed between the exposed surface 13c of the strip 10 and the upper surface 10a of the body 10 at an acute angle, the end portion 13d of the strip 13 as shown in FIG. Part of the exposed surface 13c is in line contact or surface contact with the side panel 23 as far as possible in the longitudinal direction to prevent the concrete from seeping into the exposed surface 13c and the chamfered surface is inferior. .

In addition, as shown in FIGS. 1 and 2, in the body 10, extension portions 11A and 11B are further formed on both sides of the strip 13, and in the extension portions 11A and 11B. Another form panel, for example, a plurality of fitting holes (11a) for inserting the fastening pin 25 for fastening with the side panel 23 may be formed. That is, the panels P shown in FIGS. 3A to 3D have a separate support plate due to the absence of the extension part, and the panel shown in FIGS. P allows the panel P itself to function as an independent and direct formwork panel due to the extensions 11A and 11B.

Next, look at the panels transformed into other shapes.

In the panel illustrated in FIG. 3A, the body 110 has only the extension portion omitted from the panel of FIG. 1, and the exposed surface of the strip 113 also forms an acute angle with the body 110.

Compared with the panel shown in FIG. 2A, the panel shown in FIG. 3B has the same shape as the body 210 and the exposed surface of the strip 213 is perpendicular to the body.

Compared with the panel shown in FIG. 3A, the panel illustrated in FIG. 3C has a contact surface of the strip 313 formed into a smooth curved shape, and the corners of the corresponding concrete mortar formed body will also be formed into a rounded shape. Of course, even in the case of obtaining a rounded molded body as shown in FIG. 3d, a soft portion 313A may be introduced to increase the completeness of the chamfered surface, and may be easily reshaped in the chamfering panel required for the next work. To be.

As described above, all of the panels shown in FIGS. 3A to 3D are omitted from the body, and when used in beam forming as shown in FIG. 5, a separate support plate is positioned below the panel to bind the side panel and the support plate. This structure should be supported by Jang Sun-jae, Yoke-jae, and Dong-ri.

Regarding another method for increasing the completeness of the chamfered surface of the concrete molded body, as can be seen in Figures 4a to 4d,

In the strip exposed surface 13c, the shrinkage deformation space 17 is continuously formed along the length direction of the strip. When concrete is injected into the space formed by the assembled formwork panels 10 and 23, The contracted deformation space 17 is contracted by a load so that the angle formed between the molded body contact surface 13a of the strip and the upper surface 10a of the body is increased (θ '→ θ' '), that is, as described above. As with the soft attachment 13e, the adhesiveness with the side panel 23 becomes high, and the completeness of the chamfer surface can be improved.

Here, the shrinkage deformation space 17 having various shapes may be introduced. In the panel illustrated in FIG. 4A, the shrinkage deformation space 17a having a recessed shape is formed on the exposed surface 13c of the strip 13. Compared to the panel illustrated in FIG. 4A, the panel illustrated in FIG. 4B forms a contraction-deformation space portion 17a on the exposed surface 13c of the strip, but the exposed surface 13c of the strip 13 The angle formed with the extension portion 11A forms a right angle rather than an acute angle. That is, even if the angle formed between the exposed surface 13c and the extension portion 11A of the strip is not acute, the degree of completeness of the chamfered surface is introduced by introducing the contracted deformation space portion 17a formed in the exposed surface 13c of the strip. You can get a boost effect. In particular, if the soft strip 13 with attachment 13e is introduced together with the shrinkage deformation space 17a, not only can the chamfered surface of the concrete molded body be improved, but also it can be easily and easily reshaped. The effect can be obtained.

Furthermore, the panel shown in FIG. 4C shows another form in which the extension part is omitted from the panel shown in FIG. 4B and the shrinkage deformable space part 17b is formed. In the case of the panel shown in FIG. 4D, the exposed surface of the strip is shown. (13c) and the angle formed by the imaginary extension line extending to the side of the body (10) forms an acute angle (θ) and the contracted deformation space portion (17c) is not formed on the exposed surface 13 of the strip, but the lower surface of the body More specifically, the shrinkage-deformation space portion 17c is formed in the longitudinal direction of the strip on the lower surface of the body 10b at a position corresponding to the body engaging surface 13b of the strip. This is due to the load of concrete during concrete injection due to the shrinkage deformation space portion 17c even if the shrinkage deformation space portion 17c is formed on the bottom surface 10b of the body corresponding to the body engaging surface 13b of the strip. Because the angle formed between the molded body contact surface 13a and the body 10 of the strip can be easily increased to increase the adhesion between the strip and the panel and prevent the concrete from seeping into the panel and the strip to be rugged. to be.

Next, the panel illustrated in FIG. 6 has a form in which the body 610 and the strip 613 are assembled as compared with the panel illustrated in FIG. 1, and coupling grooves 610A are formed at both sides of the upper surface of the body 610. Is formed, and the lower portion of the strip 613 is formed with a projection 613C, the coupling groove 610A and the projection 613C is slide-bonded in the form of a dovetail (dovetail) to prevent the deviation from the upper and lower directions It is structured to be. Of course, in the strip 613 shown in FIG. 6, a soft portion 613A is introduced to the attachment 613e to facilitate remolding, thereby increasing the recyclability of the panel and increasing adhesion to the other panel. You get a complete chamfer.

The assembly body and strip of FIG. 6 may be modified in various assembly forms, for example, assembly and fixing of two members using general nails, screws, adhesives, and the like.

1, 5, and 6, in the formwork panel according to the present invention, the fitting holes 11a, 611a of the extension portions 11A, 11B, 611A, 611B of the bodies 10, 610 are provided. Formed,

By utilizing other panels, for example side panels, in particular improved panels 23 commonly referred to in the art as "eurofoam", fitting holes 11a and 611a of the body and fastening holes of the side panels 23 After matching 23a), the fastening pin 25 having the head 25a for detachment prevention is inserted from the upper side to the lower side, and the exposed portions 11A, 11B, 611A, 611B are exposed below. Bonding of the two panels will be possible in such a way that the other fastening pins 25 'are fixed to the coupling holes 25b of the fastening pins 25. In FIG. 6, reference numeral 23B denotes a reinforcing bar supporting the frame member 23A and the panel body of the side panel 23.

Next, as shown in FIG. 5 showing the beams J among various concrete mortar molded bodies such as columns or walls,

In the case of the binding process, the side panel 23 is positioned at the end of the slab panel 21, and the form panel P according to the present invention is fastened to the bottom of the side panel 23. (25 ') is fixed and bound to the lower portion of the panel (P) Jangjae (27), yoke (28) supporting the Jangjae in a form orthogonal to the Jangjae, and the copper bar for the support of yoke ( 29) is located.

Subsequently, after reinforcing the reinforcement (J1), the concrete mortar is added, and then cured through a compaction process, the bottom edge is chamfered beam (J) is obtained.

Of course, even when using the panel (P) of Figure 1 having an extension, if the material of the panel does not ensure sufficient support force, a separate support plate is introduced to the lower portion of the panel (P), the lower support plate, the wire, yoke It can also be used in the form of supporting ashes and clubs. In FIG. 5, reference numeral 21A denotes a reinforcement of the slab panel 21.

Next, the panels illustrated in FIGS. 7A and 7B, which are different from the various types of panels described above, will be described.

In the panel illustrated in FIG. 7A, the strip 813 and the extension 811A are formed only on one side end surface of the body 810, and the support piece 815 protrudes at a position biased toward the end of the extension 811A. The support piece 815 is composed of a soft portion 815A made of the same material as the soft portion 813A introduced to the strip 813. By introducing the soft portion 815A into the support piece 815, only the soft portion 815A of the worn and deformed support piece 815 is replaced without having to mold the entire panel after one use of the panel. By reshaping and attaching, panel reshaping can be performed more easily and easily. According to the use, although all the said support pieces 815 can be made into a soft part, only a predetermined part of the upper end of the support piece 815 can also be comprised by a soft part.

As shown in FIG. 8A, the edge member 23A of the side panel 23 is fitted in close contact between the exposed surface of the strip 813 and the support piece 815 to form the pillar S. Located, it can be used in the form of mutual binding through the fitting hole 811a of the panel and the fastening hole 23a of the side panel using the two fastening pins (25, 25 '). Of course, at this time, the soft parts 813A and 815A are introduced to increase the adhesiveness and ease the panel reshaping.

In addition, compared to the panel shown in FIG. 7A, the panel illustrated in FIG. 7B includes a support piece 915 formed in the body 91, which is biased toward the strip 913, and as shown in FIG. 8B, the pillar ( C) The strip 913 is exposed between the exposed surface and the support piece 915 in the form in which the opposite end of the strip of the other panel is in intimate contact, and the other side panel 23 is provided in the extension portion 911A. The fastening pin 25 is inserted into the fitting hole 911a of the panel and the fastening hole 23a of the side panel, and the other fastening pins 25 'are used to bind each other.

At this time, the spacer (S) for the support is preferably interposed in the gap between the side panel 23 and the panel, the spacer (S) is a support piece 915 of the other panel in the rear of the body 910 of the panel It may be formed integrally with the thickness of the gap in the entire body portion except for the portion, or may be a protrusion form integrally formed in the rear portion of the body.

Of course, the soft portions 913A and 915A are also introduced into the strip 913 and the support piece 915 shown in Figs. 7B and 8B.

In FIGS. 7A and 7B, the shapes of the support pieces 815 and 915 are rectangular in cross section. However, the support pieces 815 and 915 may be implemented in various polygonal shapes according to the use form. 915 '). In this case, too, the soft parts 913'A and 915'A are introduced to facilitate convenience and efficiency in panel remolding.

In addition, the material of the panel shown in each drawing may be a metal, wood, or a composite material of them all, synthetic resin (including recycled synthetic resin) will be common. More preferably, a synthetic resin foamed to the body is used to reduce weight and material consumption.

In addition, it is preferable that the soft part shown in each figure is comprised from a soft synthetic resin. In other words, the manufacturing of synthetic resin is not only advantageous in the repeated molding process, but also when the panel is made of foamed synthetic resin or synthetic resin, it is bonded to the panel body in consideration of the property that the materials having the same properties are easily combined. It is because it is preferable to comprise also a soft part which becomes a soft synthetic resin.

Next, the bottom of the body of the present invention is further provided with a reinforcing member 19 as shown in FIG. When concrete is injected, a load is applied in a direction from the top surface 10a to the bottom surface 10b of the strip body 10. In order to cope with this, the thickness of the body 10 is preferably guaranteed to a certain thickness.

However, when the thickness of the body 10 is generally thick, there is a problem in that it takes a lot of cost for forming the body. Therefore, the lower end of the body 10b is reinforced in one direction or a lattice direction to secure a force that can cope with the load while lowering the cost. It is preferable to arrange a plurality of members 19. The addition of the reinforcing members 19 in this way is because the cost of the strip body 10 can be obtained while the cost is lowered.

In the present invention, as shown in FIG. 9, the reinforcement member 19 having a straight cross section having a rectangular cross section is added to the bottom of the body 10 in one direction, but may be added in a lattice form instead of one direction. It will be possible to implement in various shapes. In addition, such a reinforcing member may be implemented in the form that the strip body is inserted into the body, not the bottom of the body is sufficient enough to withstand the load of the concrete.

The various panels described in connection with the accompanying drawings are illustrated by using recycled wood panels as a support plate when the support of another support plate is needed, and by using various joining means such as fastening pins called adhesive or so-called "takapin" in the construction industry. Can be used after combining the panel of the present invention and recycled wood panel,

Various known coating agents are applied to the outer surface of the panel according to the present invention, so that when the panel is separated from the concrete molded body, it is more easily dropped, and the smoothness of the molded surface can be increased to improve the quality, and furthermore, the color and texture of the panel itself can be improved. It can also help improve.

As described above, the formwork panel for chamfering according to the present invention provides a formwork panel having a strip coupled to the body so as to serve as a chamfering function while being used directly as a formwork panel.

Soft parts are introduced into the protruding parts including the panel parts that can be easily worn during work so that the panels can be remolded by replacing only the soft parts that are worn out after work. When remolding, convenience can be achieved. Especially, the soft part introduced into the attachment part formed in the strip induces the deformation of the strip under the load of the injected concrete, thereby increasing the adhesion with the side formwork. This has the effect of obtaining a high degree of chamfering.

In addition to the soft portion (수축 部) due to the angle formed by the exposed surface of the strip and the body formed of the acute angle or shrinkage deformation space formed in the longitudinal direction on the strip to increase the adhesion to the side formwork to achieve a high degree of completion This has the effect of obtaining a chamfer.

In addition, an extension portion of the panel body is further formed on both sides of the strip and is fastened to another panel by using a conventional fastening pin, thereby having the effect of being able to function as a direct panel without using a separate support plate.

In the above description of the present invention, the formwork panel having a specific shape and structure has been described with reference to the accompanying drawings, but the present invention can be variously modified and changed by those skilled in the art, and various forms of panel structures shown in the drawings. Can be recombined with each other, and such variations, modifications, and combinations of features should be construed as falling within the protection scope of the present invention.
