The present invention relates to a connector (에 具) used in the inconor 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 inconner connector that ensures the shape retaining force of the assembled formwork and eventually does not harm the intended shape of the cast concrete structure, even if it is 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 inconor or outconor portion of the protruding or bending wall, looking at the prior art related to the inconor or outconor panel of the formwork,

Patent Registration No. 00249661 (December 27, 1999) `` Corner part construction system for concrete wall structure construction '' is a slide-outer corner clamp that is known to use an existing panel, especially Euroform, as possible without using a separate panel. The technique is described in which the inconor portion is connected to the panels using a novel right angle catching tripod and an inconor clamp.

However, the registered patent also has to be welded to the panel to be used in the other corners and other members, such as a tripod, and to use the particular panel with a particular member attached to the inner portion of the panel is less versatile.

Also related to a particular inconner end connector,

Utility Model Publication No. 1995-0003711 (1995.05.13) `` Desorption Structure of Building Formwork for Construction '',

Registered Utility Model No. 0345038 (2004.03.04) 『Building Formwork』, which presented both inner and out corner members.

Utility Model Registration No. 0241690 (July 26, 2001), Easy to connect with Euroform, Formwork Inner Frame and Utility Model Registration No. 0357642 (July 20, 2004).

However, they all have a firm structure and have no liquidity at all.

Insert the inner connector between the already assembled panel and the panel,

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 inner 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.

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 an inner mold will be made of a metal material, and once used for wall construction, concrete will adhere to the shaft portion, which is inconvenient because angle adjustment is not easy when using the inner mold.

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

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

Next, in the inner connector (C) according to the present invention, an operation of forming a reinforcement bar or opening or narrowing the main powder and / or the auxiliary powder to each other is provided in the main bending portion and / or the auxiliary bending portion of the panel contact portion. By introducing an incision for easy making and a filling body in the incision, the functionalities of strengthening strength, guaranteeing fluidity for easy assembling and disassembling, and ensuring simultaneous fluidity and durability are also introduced.

First, the inner connector (C) according to the present invention, as can be seen in Figure 2 (a) and (b), the secondary bending of the main bending portion 13 or the panel contact portion 20 of the structure contact portion 10 The reinforcing bar 13A, 23A, 113A, 123A, which is thicker than the other parts of the connector, is formed at the outer part of the part 23, or both of them, so that bending of the shape deformation stress is applied during assembly and disassembly. Preferred for reinforcement of the site.

In addition, one of the core of the inner 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 Figure 3 panel contact portion 20 Auxiliary powder 21A (21B) forming

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 unfolding operation will be easier than the narrowing 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 inconor connector C shown in FIG. 5 is a soft synthetic resin in the cutout 115 formed in the cutout, in particular, the major bent portion between the two structure contacting portions 10, with the connector shown in FIGS. 3 and 4. Is filled in.

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, in particular the main bent portion of the inner connector,

The soft synthetic resin filler 115A filled in the cutout 115 may be provided in the cutout portion of the auxiliary bent portion as well.

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 contact portion and the panel contact portion made of synthetic resin in the inner connector (C) shown in FIG. 5 are formed of a synthetic resin mixed with a foaming agent on a central portion 17B indicated by a single-dot chain line, and micropores are formed. It is formed so that a light weight effect and a 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 pin 50 is inserted into the fastening holes 43 and 27 so that the frame contact portion 20 of the edge member 41 of the other general panel 40 and the panel contact portion 20 of the present invention are in close contact with each other. In old 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 low 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 features of the inconor connector according to the present invention. 21B) spreading and narrowing operation may not be guaranteed.

In order to solve this problem, in the inner connector C according to the present invention, as shown in FIG. 4, each auxiliary powder 21A of the panel contact part 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 of the fastening hole 27 formed in the auxiliary powder 21A (21B) of the panel contact portion 20 of the inner corner connector (C) according to the present invention and the general panel 40 of the border member 41 The fastening hole 22a corresponding to the fastening hole 43 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.
