The present invention relates to a connector (에 具) used for the out-corner part when assembling the formwork panel for concrete structures such as walls or pillars when building buildings,

In more detail, a synthetic resin material panel having a predetermined thickness constitutes a panel contact part connected to a structure contact part and a general panel such as a euroform,

The panel contact portion is formed with a resistance member that intersects the protrusion formed on the inside and outside of the general panel, it can reinforce the bearing force against the pressure acting in the outward direction when the concrete is put into the assembled formwork. The present invention relates to a formwork out-corner connector, which ensures the shape retaining force of the assembled formwork and does not harm the intended shape of the cast concrete structure even when made of a synthetic resin material having low rigidity.

Panels for building formwork are known from a variety of early veneer plywood panels to facilitate the recent assembly and disassembly of formwork, as well as various improved panels represented by Euroform.

In terms of materials, they are being diversified into wood, represented by veneer plywood, and special synthetic resins such as FRP, steel, or alloy materials.

The direction of change of the formwork panel is to shed light on the architectural trend of the high-rise building and the high-rise building represented by the apartment.

Euroforms, which represent conventionally improved panels, are well illustrated in Utility Model Registration No.0205912 (2000.09.27), "Form side panels for formwork".

Conventional panels, including the Euroform described in the registration utility model requires a separate member for the out-corner or out-corner portion of the protruding or bending wall, looking at the prior art related to the out-corner or out-corner panel of the formwork,

First, the formwork panel meets the normal state, especially the orthogonal state as it is fixed, the connector itself is related to the form that does not contact the concrete of the wall

Republic of Korea Patent No. 00249661 (December 27, 1999) `` Formwork system for constructing the nose part of concrete wall structure '', and

Utility Model Registration No. 0339867 (2004.01.14) has a formwork angle.

In addition, it relates to the connector of the form of direct contact with the concrete of the corner wall while connecting the usual formwork panel,

Utility Model Publication No. 1993-0006808 (1993.10.07) `` Connecting device for concrete formwork ''

Utility Model Registration No.0205912 (2000.09.27) `` Side end panel for formwork '', and

Utility Model Registration No. 0345038 (2004.03.04) There is a building formwork.

However, the out-corner connector for the conventional wall of the form as described above all make the edge of the molded wall is linear.

The same is true of concrete trying to penetrate the voids of the fluid, so the molded linear wall corners are not smooth and have a sharp and rugged shape. This requires post-processing of the corners of the wall, causing air delays and building costs.

In addition, the conventional out-corner connector has a corner portion of the molded wall to form a non-linear surface, but there was a problem that the connection to the conventional formwork panel is complicated and the firmness is weak.

Furthermore, all conventional out-corner connectors have a firm structure and do not have any fluidity.

Insert out-corner connections between already assembled panels and panels,

If you need to build corners outside a certain angle, such as right angles,

If the floor is not flat and the assembled panel is broken,

It cannot cope with the situation that needs to adjust the angle of the outer corner.

On the other hand, Utility Model Registration No. 0086363 (1995.03.08) `` Corner plate structure of wall frame for producing prefabricated concrete building of cube type '' screws the corner plate with elasticity to the wall panel and installs and dismantles the corner guide separately. One technique is presented that allows for the operation of

Not only is it difficult to operate corner guides on a construction site,

Considering the process of increasing the density of the structure to be constructed by putting concrete into the assembled formwork and impacting it with a compactor or vibrator due to the elasticity of the corner plate, the corner plate having elasticity is broken or twisted in this process. Problems such as cracking or cracking are expected.

If the thickness of the corner plate is increased in order to prevent this, elasticity is inevitably reduced so that the intended advantage is lost.

In addition, Utility Model Registration No. 0257253 (Nov. 30, 2001), `` Inconor Molding, '' provides a technology that allows the angle adjustment of two plates around a shaft to form corner portions of various angles.

Such in-corner molds will be made of a metal material, and once used for wall construction, concrete will be inevitably stuck to the shaft portion, which is inconvenient since angle adjustment is not easy when using out-corner molds.

In particular, since the form storage of the registration utility model will be made folded after dismantling the form, it will be more difficult to unfold the form upon reuse.

However, melting and re-manufacturing the mold is inappropriate because it increases the supply cost of the mold.

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 describing the formwork out-corner connector (C) according to the present invention, the direction reference is specified with reference to the part shown in plan view in the lower part of FIG.

The main bent portion 13 of the two main powders 11A and 11B constituting the structure contact portion 10 is defined as the 'center', and the opposite sides of the main bent portion are 'sides'. Determined by

In the assembled formwork, the side that comes into contact with concrete is set as 'inside', and the opposite side is set as 'outer'.

As shown in Figure 1, the formwork out-corner connector (C) according to the present invention is the main main bending portion 13 of the two main powder constituting the concrete structure (W), in particular the contact portion 10 in contact with the wall ) Are bent at an angle (90 degrees in the drawing) to each other,

The inner surface of the main bent portion 13 is rounded so that the outer corner connector (C) can be easily separated from the concrete structure (W) when dismantling the form after curing the concrete.

The two main powders 11A and 11B have a height corresponding to the height of the concrete structure W, in particular the wall to be constructed, and an angle corresponding to the angle of the wall out-corner portion to be constructed.

Here, the main powder is 'corresponding' to the height of the concrete structure when the height of the total concrete structure is 2m, the height of the main powder (11A) (11B) is 2m, or evenly or unevenly divided the height of 2m ( Example: a height of 1m or 0.5m).

Outer corner connector (C) according to the present invention is coupled to the side end of each main powder (11A) (11B) of the structure contact portion 10 and bent outwardly to the auxiliary powder (21A) (21B) It comprises a panel contact portion 20 made of,

The structure contacting portion 10 and the panel contacting portion 20 are preferably integrally injection molded to reduce manufacturing cost, and basically various kinds of hardeners such as hardeners to ensure strength suitable for use as a formwork panel in a synthetic resin such as urethane foam. Physical properties can be specified by additive mixing.

In addition, the panel contact portion 20 may be the same as the length of the structure contact portion 10, but may be deformed to form a sparse auxiliary powder is coupled at a predetermined interval,

The length of the panel contact portion 20 is the thickness of the structure contact portion 10 may be the same or different, the thickness thereof is generally thickened or thinner depending on the strength of the material may be 10 ~ 25mm,

The width of the auxiliary powder (21A) (21B) constituting the panel contact portion 20 is preferably a size corresponding to the width of the rim member 41 of the general panel 40 shown in FIG.

In general, the panel 40, in particular the Euroform panel, as shown in Utility Model Registration No.0205912, allows a tool such as a presser foot puller (so-called 'Paru') to be formed by forming a gap between the panel and the panel contact surface when dismantling the formwork. It is common that protrusions 41a and 41b are formed on the outer side of the rim member 41 in order to ensure a space that can be increased, thereby increasing work convenience.

Outer corner connector (C) according to the present invention when the concrete is put in the assembled state using the other panels 40, 40A, fastening pin 50, tie rods 53, etc. It works

In order to enable mass production and to reduce the cost, the out-cone connector is made of synthetic resin, especially recycled synthetic resin, so the rigidity is inferior. Therefore, it is insufficient to guarantee the shape retention of the assembled formwork.

Eventually, when the concrete is put in, the general panel and the out corner connecting part are opened so that they do not come into close contact with each other.

Furthermore, there may be a problem that the cast concrete structure does not cure to its intended shape.

In the out-corner connector (C) according to the present invention, in order to prevent the occurrence of such a problem, a resistance member that can interlock with protrusions 41a and 41b formed on the edge member 41 of the general panel 40 is used. It was considered to increase the mutual binding force between the general panel 40 and the out-corner connector (C) forming the assembled formwork by introducing.

The shape, arrangement position, and dimensions of the resistance member introduced into the out-corner connector (C) according to the present invention can not be limited by the protrusion formed on the rim member of the general panel,

As shown in FIG. 1, since the protrusions 41a and 41b formed on the edge member 41 in the general panel 40, particularly in the euroform, are biased toward inner and outer ends of the edge member, as shown in FIG.

The resistance member of the out-corner connector (C) according to the present invention will be in the form of intersecting the inner and outer protrusions and the outer and inner, respectively,

At this time, if only one resistance member 30 is formed at a position intersecting with the protrusion 41a formed on the outside of the general panel 40, the concrete member is acted outwardly by the input of concrete from the assembled formwork. It will be enough to cope with stress.

In addition, the out-corner connector (C) according to the present invention in order to facilitate the dismantling convenience by ensuring a space that a tool such as a presser foot puller (so-called 'paru') can be put in when dismantling the form after curing the concrete.

It is preferable to form the recesses 21a and 21b in the auxiliary powders 21A and 21B of the panel contact part 20 so that a gap G is formed upon contact with the general panel 40.

In particular, the width of the gap G formed between the recessed portions 21a and 21b of the connector C and the two protrusions 41a and 41b of the general panel 40 in FIG. Due to the symmetrical shape is ensured by the support protrusion 33 formed on the inner side of the 30,

The support protrusion 33 contacts the inner protrusion 41b of the frame member 41 of the general panel 40 in the assembled formwork.

As such, the outer corner connector for formwork according to the present invention has a structural simplicity due to the resistance member 30 and the support protrusions 33 provided on the outer side of the two auxiliary powders 21A and 21B of the panel contact portion 20. Due to this, economic efficiency, ease of assembly, robustness of assembly state, and ease of disassembly can all be achieved.

Next, as shown in FIG. 1, a plurality of fastening pins 50 may be inserted into the auxiliary powders 21A and 21B of the panel contact portion 20 for connection with other general panels 40. It is preferable that the fastening hole 27 is formed.

In particular, the fastening hole 27 should have a position and shape corresponding to the fastening hole 43 formed in the rim member 41 of the general panel, such as the flow-form panel 40.

As shown in FIG. 1, the fastening pin 50 is inserted into the fastening hole 27 and narrowed to the narrow portion 51b of the end portion so as to be easily inserted in the first time, and the fastening pin 50 is separated from the fastening hole. It has a head 51a for preventing, and an insertion hole 51c for inserting another fastening pin 50.

In addition, the out-corner connector (C) according to the present invention is to form a binding with the counter-panel panel 40A assembled in a state spaced apart from the opposite side of the general panel 40 bound to the out-corner connector to form the concrete structure (W). For the tie rod 53 for the auxiliary powder side of the panel contact portion it is preferable that the fitting groove is formed at a predetermined interval,

Arrangement position, spacing, dimensions of the fitting groove will eventually be determined according to the tie rod fitting groove 45 formed on the side of the general panel,

In Figure 1, the out-corner connector (C) is provided with fitting grooves 31 (33a, see Fig. 4) in the resistance member 30 and the support projection 33, respectively,

Fixing of the tie rod 53 is fastened to each of the corner connector (CI) and the panel 40 and the outer corner connector (CO) and the panel (40A) by the fastening pin 50 as in the assembly method known in the construction industry It is made in such a way that it is held in place.

Further, in the outer end of each of the auxiliary powders 21A and 21B of the panel contact portion 20 in all the connectors C shown in FIGS. 1 to 5, the wedge portion formed by cutting the central edge thereof, in particular, is rounded. The wedge portion 21c is further formed, which may contribute to aesthetic improvement and material reduction.

Next, in the out-corner connector C according to the present invention, a reinforcing bar is formed in the major bent portion of the structure contact portion and / or the auxiliary bent portion of the panel contact portion, or the main powder and / or the auxiliary powder are opened or narrowed to each other. An incision was made to make this easy, and a filler was introduced in the incision to ensure the introduction of functionality such as strength reinforcement, ensuring fluidity for ease of assembly and disassembly, and ensuring simultaneous fluidity and durability.

First, as shown in (a) and (b) of FIG. 2, the out-corner connector C according to the present invention supports the main bent part 13 of the structure contact part 10 or the auxiliary part of the panel contact part 20. The reinforcing ribs 13A, 23A, 113A, and 123A thicker than the other portions of the connector are formed at the bent portion 23 or the outer portion of both of them, so that a large amount of shape deformation stress is applied during assembly and disassembly. It is preferable for reinforcement of the bent portion.

In particular, as shown in (a) of FIG. 2, the reinforcement 13A formed inside the major bent portion 13 of the structure contacting portion 10 serves as a chamfer molding portion for chamfering the out-conor portion of the cast structure W. The shape of the chamfer molded part may be variously modified, such as straight, inward or outwardly curved.

In addition, one of the core of the out-corner connector according to the present invention is bent and connected to each of the main powder (11A) (11B) constituting the structure contact portion 10 as shown in (a) and (b) of FIG. 20, the auxiliary powder 21A (21B)

Cutouts 25A and 25B formed in each of the auxiliary bent portions 23 corresponding to the connection portions with the main powders 11A and 11B side ends of the structure contacting portions 10,

The role of the incision is to facilitate the operation of opening or narrowing the two powders 11A, 21A, 11B, 21B with respect to the bend 23.

The cutout may be formed such that the two powders 11A, 21A, 11B, 21B can be easily opened and narrowed at the same time, or can only be opened.

In the connector C shown in FIG. 3A, the cutout 25 is an auxiliary bending part 23 that forms a predetermined angle (eg, 90 degrees) over the entire length of the structure contacting portion 10 and the panel contacting portion 20. And a cutting line 25b formed in the cutting hole 25a and cut out toward the outside of the concrete structure to be constructed in the cutting hole 25a.

Since the main and auxiliary powder pairs 11A, 21A (11B, 21B) are always in contact with each other at the incision 25b, the unfolding operation will be easier than the narrowing operation. The connector C having such an incision 25 can contribute more to the firmness required for the built formwork.

In the connector (C) shown in FIG. 3 (b), the cutout is formed in the auxiliary bent portion 23 also forming an angle (eg, 90 degrees) over the entire length of the structure contact portion 10 and the panel contact portion 20. It is made, but made of a concave inlet groove 125 opened toward the outside of the concrete structure to be constructed in the bent portion,

Each of the main and auxiliary powder pairs 11A and 21A and 11B and 21B is capable of both narrowing and unfolding operations.

Which of these various types of incisions is chosen depends on the conditions of the construction site, the form of the building and the construction method.

In contrast, the connector (C) shown in Figure 3 (c) is that the incision that forms the core of the present invention is formed in the main bent portion 13 between the two main powder (11A) (11B),

The cutout 15 is formed in the cutout 15a formed in the bent portion 13 to form a predetermined angle (for example, 90 degrees) over the entire length of the structure contacting portion 10, and the cutout 15a is constructed in the cutout 15a. It is made of an incision line (15b) cut toward the outside of the concrete structure to be.

Since the two main powders 11A and 11B are always in contact with each other in the incision line 15b, the narrowing operation will be easier than the spreading operation.

The various forms of incision, including the incision form of FIG. 3 (c) and the incision form of FIG. 3 (a) or FIG. 3 (b), can be implemented in all or in combination in one connector.

Subsequently, the formwork out-cone connector C shown in FIG. 5 is soft to the cutout 115 formed in the cutout, in particular the major bent portion between the two structure contacting portions 10, with the connectors of the type shown in FIGS. 3 and 4. The difference is that the resin is filled.

Filler 115A (indicated by dotted lines) provided in the cutout compensates for the problem that the two main powders 11A and 11B are broken when the angle is adjusted due to the cutout 115 in the main bent portion. In order to avoid problems in the angle adjustment function of the bent portion, particularly the main bent portion of the outer corner connector,

The soft synthetic resin filler 115A filled in the cutout 115 may also be provided at the cutout of the auxiliary bent part.

The structure contact portion and the panel contact portion may also be a synthetic resin, preferably a synthetic resin having a mutual bonding force with the incision filler, and more preferably, the same material as the incision filler but a hard synthetic resin having only physical properties.

In addition, the structure contacting portion and the panel contacting portion in the out-corner connector (C) shown in FIG. 5 are made of synthetic resin, and are molded into a synthetic resin mixed with a foaming agent on the center portion 17B indicated by a single-dot chain line. Is formed so that the weight reduction effect and material saving effect can be obtained,

In addition, the outer portion 17A is formed of a synthetic resin in which no blowing agent is mixed or mixed in a small amount, so that the particle composition has a dense and hard property, thereby obtaining an effect that there is no problem in durability.

On the other hand, synthetic resins generally have greater shrinkage when pressure is applied compared to metals.

The fastening pins 50 are inserted into the fastening holes 43 and 27 so that the edge member 41 of the other general panel 40 and the panel contact part 20 of the out-corner connector C according to the present invention are in close contact with each other. In assembled formwork

When the concrete is put in order to increase the density of the structure to be constructed and the impact is applied to the compactor or the vibrator, the panel contact portion 20, the auxiliary powder 21A (21B), in particular the head of the fastening pin 50 is subjected to a lot of impact The portion of the fastening hole 27 contacting the portion 51a may be pressure contracted.

As a result, a gap is formed between the auxiliary powders 21A and 21B, which are firmly adhered to each other, and the edge member 41 of the general panel 40, which causes concrete problems because the concrete is pulled out of the gaps. Become,

Even if the concrete is not ejected, the cracks that are opened may cause the cured concrete structure to become rugged rather than vertical.These uneven parts must be changed into grinders one by one to increase construction costs, increase air, and reduce building durability. Can cause.

In order to prevent such a phenomenon, a special synthetic resin may be used, but since the material cost increases by that amount, it is not preferable.

Synthetic resins with high hardness may generally have a drop in elasticity corresponding to the hardness, so that the main and auxiliary powder pairs 11A, 21A (11B) due to the incision, which is one of the characteristics of the outcorner connector according to the present invention. , 21B) spreading and narrowing operation may not be guaranteed.

In order to solve this problem, in the outer corner connector C according to the present invention, as shown in FIG. 4, each auxiliary powder 21A of each of the panel contact parts 20 contacting the head 51 a of the fastening pin 50. It was conceived to introduce the reinforcing member 22 in preparation for the fastening pin on the central side of 21B. The reinforcing member 22 may be made of a metal material or another material corresponding to a metal having a degree of compression.

In addition, the reinforcing member 22, the fastening hole 27 formed in the auxiliary powder 21A (21B) of the panel contact portion 20 of the outer corner connector (C) according to the present invention and the general panel 40 border member 41 Fastening hole 22a corresponding to the fastening hole 43 of the should be formed,

The reinforcing member 22 may have a length corresponding to the entire length of the auxiliary powder 21A, 21B, or may have a length arranged only at a position of the fastening hole 27 of the auxiliary powder.

In addition, the auxiliary powder (21A) (21B) of the panel contact portion 20 is preferably formed with a receiving groove for receiving the reinforcing member on the surface facing the center.

As shown in Figure 4 (a), the receiving groove is simply a groove 128 having a depth corresponding to the thickness of the reinforcing member,

As shown in FIG. 4B, the reinforcing member 22 may be a slide groove 129 having two separation preventing pieces 129a for preventing the reinforcing member 22 from being separated toward the center after being fitted in the longitudinal direction.

The reinforcing member coupled to the slide groove 129 shown in Figure 4 (b) may be of a type corresponding to the shape of the slide groove, not a flat plate.

Hereinafter, look at the form assembly process of the out-corner portion using the formwork out-corner connector according to the present invention described above.

First, as shown in FIG. 1, the general panel 40, in particular, the euroform panel 40, is left and right and / or using the fastening pin 50 inserted into the fastening hole 43 of the rim member 41 of each panel. Or when connecting up and down to reach the portion to form a corner connecting connector (C) of the present invention,

In this case, when the Eurofoam panel 40 is already assembled at both sides of the panel contact part 20 of the connector and the two auxiliary powders 21A and 21B, only the seat for the connector C of the present invention is empty (FIG. 3B).
