At the same time, the inner corner of the synthetic resin material can be made as thin as possible to minimize the material consumption and to ensure durability.

It is much cheaper than existing wood or metal inconor member, and it meets durability. It can improve the quality of molding surface of concrete structure, and it can be used after melting 2 ~ 4 times and melted and recycled. The present invention relates to a connecting system for a formwork inconor member incorporating a connector.

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, wood is represented by veneer plywood, special synthetic resins such as FRP, and metal materials such as steel or alloys.

The change direction of the formwork panel is intended to contribute to the architectural trend of large-scale assembly buildings or high-rise buildings represented by high-rise buildings and apartments.

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 corner member,

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. A technique is presented to enable the operation of.

In order to be practically applicable to the construction site in relation to the improvement of the corner members, in particular the corner member, it is important that the price competitiveness is secured and the quality of the molded concrete structure is excellent.

In particular, in order to improve the molding quality of the concrete structure, the concrete and the inconor member should not have adhesion to each other. To this end, various coating materials have been developed and used.

In addition, when considering the process of increasing the density and strength of the structure to be built by putting concrete into the assembled formwork and impacting it with a compactor or vibrator, the inner corner member is pushed and deformed by impact and pressure so that the gap with the general panel does not open. It is important.

However, in the conventionally known inconor member including the above known technology, it is confirmed that there is no example of providing a technology capable of satisfying both durability and molded products of the structure while supplying a low cost product.

On the other hand, the technology related to the connector for the extension of the inconor member lacking in relation to the conventional formwork panel, in particular the inconor member

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now 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 system S for the formwork inconor member C according to the present invention, the direction reference is specified with reference to FIG.

The main bent portion 13 of the two main powders 11A and 11B constituting the structure contact portion 10 of the inner corner member C is set as the 'center', and the main bent Define opposite sides of wealth as "sides,"

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

As shown in the illustrated concrete structure (W) is a wall of the building to determine the top and bottom based on the direction of gravity.

Forming corners in the connection system S according to the present invention as shown in Figs. 1 and 2 (the connector shown in Fig. 2 differs in that the supporting piece 49A is further formed as compared to the connector shown in Fig. 1). The member C may be injection molded from a synthetic resin material, and the two main powders constituting the concrete structure W, in particular, the contact portion 10 which comes into contact with the wall, may be angled at a central main bent portion 13. (90 degrees in the drawing) interconnected in a bent state,

The inner center of the main bent portion 13 is rounded so that the inconor member 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 built, and an angle corresponding to the angle of the wall inconor portion to be built.

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 ( For example, a height of 1m or 0.5m, etc.)

In particular, considering the introduction of the connector (J) forming the core of the present invention, the length of the corner member (C) will be shorter than the height of the structure (W).

The inner corner member (C) is coupled to each main powder (11A) (11B) side end of the structure contact portion 10 and the panel contact portion made of auxiliary powder (21A) (21B) is bent outwardly protruding Including 20,

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

The panel contact portion 20 may have the same or different thicknesses of the structure contact portion 10, and the thickness thereof may be generally 8 to 25 mm thick or thin depending on the strength of the material.

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 31 of the general panel 30 shown in FIG.

In general, the panel 30, in particular the Euroform panel, as shown in Utility Model Registration No.0205912, forms a gap between the panel and the panel contact surface when dismantling the mold, so that a tool such as a presser foot puller (called 'Paru') is introduced. It is common that protrusions 33a and 33b are formed on the outer side of the rim member 31 in order to ensure a space that can be made and increase work convenience.

The inner corner member (C) when the concrete is put into the state using the other panels 30, 30A, fastening pins 35 and tie rods 37 and the like assembled, the pressure acts outward,

In order to enable mass production and to reduce the cost, the rigidity of the inner corner member is not good enough to ensure the shape retention of the assembled formwork.

Eventually, when the concrete is put in, the general panel and the inconor connection part do not come into close contact, and concrete leakage occurs.

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

In the inner corner member (C), in order to prevent the occurrence of such a problem in advance, the formwork assembled by introducing the engaging projections that can interlock with the protrusions (33a, 33b) formed on the rim member 31 of the general panel (30). Considering to increase the mutual cohesion of the general panel 30 and the inner corner member (C) to form to some extent.

The shape, arrangement position, and dimensions of the locking projections introduced into the corner member C are limited by the protrusions formed on the edge members of the general panel.

As shown in FIG. 1, since the protrusions 33a and 33b formed on the edge member 31 in the general panel 30, particularly in the euroform, are biased toward inner and outer ends of the edge member, as shown in FIG.

The projection of the corner member (C) is preferably in the form of interdigitation between the inner and outer protrusions and the outer and inner, respectively,

At this time, if only one locking projection (24a) is formed in the position intersected with the protrusion (33a) formed on the outside of the general panel 30, the stress acting in the outward direction of the inner corner member by the input of concrete from the assembled formwork substantially Will be sufficient to respond.

In addition, in the inner corner member (C) in order to facilitate the dismantling convenience by ensuring a space in which a tool such as a presser foot puller (so-called 'Paru') can be put in when dismantling the form after curing the concrete.

Preferably, a gap G is formed between the auxiliary powders 21A and 21B of the panel contact part 20 and the general panel 30.

In particular, the width of the gap G formed between the panel contact part auxiliary powder of the inner member C and the two protrusions 33a and 33b of the general panel 30 in FIG. This is due to the symmetrical shape being ensured by the supporting protrusions 24b formed on the inner side of the support (called 'supporting' protrusions in order to contrast with the main function of the 'hanging').

The support protrusion 24b contacts the inner protrusion 33b of the frame member 31 of the general panel 30 in the assembled formwork.

As such, the formwork inconor member has structural simplicity due to the locking protrusions 24a and the supporting protrusions 24b provided on the outer side of the two auxiliary powders 21A and 21B of the panel contact portion 20. Ease of assembly, assembly robustness, and ease of disassembly can all be achieved.

Next, as shown in FIG. 1, a plurality of fastening pins 35 may be inserted into the auxiliary powders 21A and 21B of the panel contact part 20 for connection with other general panels 30. It is preferable that the ball 22 is formed,

In particular, the fastening hole 22 should have a position and shape corresponding to the fastening hole 32 formed in the rim member 31 of the general panel, such as the flow-form panel 30.

As shown in FIG. 1, when the fastening pin 35 is inserted into the fastening hole 22, the fastening pin 35 is inserted into the fastening hole 35b and the fastening part which narrowed the width of the end portion so that the initial injection is easy. It has a head (35a) for preventing, and the insertion hole (35c) for the insertion of the other fastening pin (35).

In addition, the inner corner member (C) is a tie rod (37) for binding with the counter panel (30A) assembled in a state spaced apart from the opposite side of the general panel 30 bound to the inner corner member to form the concrete structure (W) It is preferable that fitting grooves are formed at a predetermined interval on the side of the auxiliary powder of the panel contact part.

Arrangement position, spacing, dimensions of the fitting groove will eventually be determined according to the tie rod fitting groove 34 formed on the side of the general panel,

In the inner corner member C illustrated in FIG. 1, fitting grooves 26a and 26b are formed in the locking protrusion 24a and the supporting protrusion 24b, respectively.

The tie rod 37 is fixed to each of the inconor member C and the panel 30 and the outer corner member CO and the panel 30A by the fastening pin 35 as in the assembly method known in the building industry. It is made in such a way that it is fixed in the ball position.

Further, as can be seen in Figures 1 and 4, the outer edge of each of the auxiliary powder (21A) (21B) of the panel contact portion 20 in all the inner corner member (C) shown in the wedge portion cut off the center edge In particular, the wedge portion 21a processed in a round shape is further formed.

When the fastening pin 35 for connection with the other panel 30 is inserted through the space between the two auxiliary powders due to the wedge portion, the width of the operator's hand can be widened, so that it is preferable. You can also contribute.

Next, in the corner member C, a reinforcing material is formed in the major bent portion and / or the auxiliary bent portion of the panel contact portion, or the main powder and / or the auxiliary powder are made to be easily opened or narrowed with each other. It is desirable to introduce an incision for

First, as shown in (a) and (b) of FIG. 4, the inner corner member C may be a major bent part 13 of the structure contact part 10 or an auxiliary bent part 23 of the panel contact part 20. It is preferable for the reinforcement of the bent part to which the shape deformation stress is exerted much in the assembly and disassembly process by forming the reinforcing material 13A, 23A which is thicker than the other part of the inconor member in the outer part).

In addition, one of the cores of the inner corner member is bent and connected to each of the main powders 11A and 11B constituting the structure contact portion 10, as shown in (c) of FIG. 4 to form the panel contact portion 20. ) (21B)

It is a cutout portion 25 formed in each of the auxiliary bent portion 23 corresponding to the connection portion with the main powder 11A (11B) side end of the structure contact portion 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 incision may be formed so that the two powders (11A, 21A) (11B, 21B) can be easily opened and narrowed at the same time, or only open operation,

In the inconor member (C) shown in FIG. 4 (c), the cutout portion 25 is an auxiliary bent portion forming a predetermined angle (for example, 90 degrees) over the entire length of the structure contact portion 10 and the panel contact portion 20 ( 23, but is formed in the recess groove opening 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.

On the contrary, the inconor member C shown in FIG. 4 (d) is formed at the major bent part 13 between two main powders 11A and 11B, which is a cutting part forming the core of the present invention.

The cutout 15 is formed in the cutout 15a formed in the bent portion 13 at 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.

Many other types of incisions, including these incision forms, can be implemented in all or in combination with one inconor member.

Next, the connector (J) for connecting the inner (C) shorter (or lower) than the structure (W) to be constructed in the connection system (S) according to the present invention will be described.

As shown in Figure 1, the connector (J) is composed of both the fitting portion 40 and the locking portion 49,

The fitting portion 40 is a main support portion 41A (41B) in contact with the outer surface of the main powder (11A) 11B constituting the structure contact portion 10 of the inner member (C),

It consists of the auxiliary support portion 43A (43B) in contact with the outer surface of the auxiliary powder (21A) (21B) forming the panel contact portion 20 of the inner member (C),

Both fitting portions 40 are preferably symmetrical in length or shape, but are not essential.

In addition, the locking portion 49 is located between the two fitting portions 40, the concrete formed by matching the shape and dimensions of the outer structure of the structure contact portion 10 and the panel contact portion 20 of the inner corner member (C) as possible It is preferable to make the structure (W) smooth without forming irregularities.

In particular, for the quality of the molded surface of the concrete structure, the engaging portion 49 preferably overlaps the structure contact portion with the shape and the size of the overlapping portion with the structure contact portion 10 of the inner member.

It is important that the portion overlapping with the panel contact portion 20 of the corner member does not prevent the general panel 30 and the corner member from being closely bound.

However, considering that the engaging portion 49 of the connector (J) is introduced to clarify the boundary of the corner member (C) coupled to the upper and lower fitting portion 40 of the connector (J),

In addition to the protruding engaging portion 49 clearly forming a border as shown, the cross-sectional area of the middle point of the connector is the largest and tapered form that the cross-sectional area becomes smaller toward both upper and lower ends, and is coupled to the upper and lower ends of the connector. The inner corner members may be deformed to be in contact with each other.

In addition, in the case of introducing the support piece 49A of the connector shown in FIG. 2 or the coupling protrusion 44 of FIG. 3, which will be described in more detail below, the function of the locking portion 49 may serve as the support piece or the coupling protrusion. The latching portion can be omitted since it becomes unnecessary as it is absorbed and integrated.

Furthermore, in FIGS. 1 and 2, each of the fitting portions 40 of the connector J is connected to the supporting portions 41A and 41B and the auxiliary supporting portions 43A and 43B at each end thereof.

In addition, the opening part 100 formed between the auxiliary supporting parts 43A and 43B is connected to each other by a joint 45 provided at the connector J when the connector J is fastened.

The approximate cross-sectional shape is pentagonal,

This is a shape generally coinciding with the outer surface shape of the main powder (11A) 111B and the auxiliary powder (21A) (21B) of the inner corner member (C) interconnected.

Furthermore, in the fitting (J) according to the present invention, the fitting portion 40 is further provided with a reinforcing bar 47 for interconnecting the supporting portions 41A, 41B and the auxiliary supporting portions 43A, 43B.

By reducing the material consumption, it is possible to provide the lowest cost products possible while ensuring light weight and durability.

The shape of these reinforcements can vary,

On the other hand, due to the introduction of the reinforcement bar, it is possible to implement a connector in the form of connecting through the reinforcement bar without being connected to the support base, the auxiliary support, even the joint.

Subsequently, the auxiliary powder of the panel contact portion 20 of the inner member C is connected to the engaging portion 49 provided in the auxiliary supporting portion 43A and 43B of the connector J in the connecting system S according to the present invention. Each of the supporting pieces 49A which are in contact with the side surfaces of 21A and 21B is further provided.

Due to the support piece 49A

The fitting portion 40 of the connector J is surrounded by the outer surface of the structural contact portion 10 and the panel contact portion 20 of the inner member, and the connector J and the inner member C are formed by the interference fit. ) Can be employed to maintain a strong bond,

In addition, or as an alternative thereto

The connector and the inconor member can obtain a firm coupling relationship between the support piece 49A and the engaging portion 49 of the connector J such that the panel contact portion 20 of the corner member C is fitted. Will be.

Furthermore, due to the support piece 49A of the connector J, the panel contact portion 20 of the corner member C is prevented from being mutually opened.

Due to the fitting portion 49A of the connector, the panel contact portion 20 of the corner member C is also prevented from being retracted.

As a result, it is expected that the effect of increasing the rigidity of the corner member may be obtained.

In addition, as mentioned above, the engaging portion 49 may be omitted due to the introduction of the support piece 49A, wherein the support piece is the auxiliary powder 21A of the panel contact part 20 of the inconor member C. A connecting piece is provided to space the support piece away from the auxiliary support of the connector so as to be able to come into contact with the side of the blade 21B.

Meanwhile, FIG. 3 shows a connecting piece different from the connecting piece shown in FIG. 2.

The illustrated connector (J) is to be inserted into the fastening hole 22 of the panel contact portion 20 of the inner member (C) coupled to the fitting portion 40 above and below

Coupling protrusions 44 are formed at the side parts of the fitting part 40 and the supporting parts 43A and 43B.

The arrangement position, the shape and the size of the coupling protrusion 44 will be determined corresponding to the fastening hole 22 of the panel contact portion 20 of the inner member (C),

Also, the locking portion 49 of the connector may be omitted due to the coupling protrusion 44.

Furthermore, it is preferable that the coupling protrusion 44 has an inclined portion 44a so as to easily move on the outer surface of the auxiliary powders 21A and 21B of the inner member C.

In the drawing, the coupling protrusion 44 is inclined in the inclined direction of the upper portion of the locking portion 49 from the lower side to the upper side in consideration of the case where the connector J is inserted from the upper side to the lower side. It is in the form of a photograph, the engaging projection inclined portion of the lower portion is formed in the opposite direction.

In particular, the connector J shown in FIG. 3 has some elasticity due to the characteristics of the synthetic resin material, and the elastic force is increased due to the incisions 15 and 25 described above.

Slightly spread the connector (R) by slightly opening the main body (11A) (11B) and the panel contact (20) auxiliary powder (21A) (21B) of the structure contact portion 10 of the inner corner member (C). This can be done.

Thus, in the connection system (S) according to the present invention, the connector (J) is inevitably used to increase the length of the insufficiently inconor member (C), as necessary or intentionally of the inconor member (C) Since it can be used as a reinforcing means to increase durability

For example, even if the height of the designed concrete structure (W) is 2m and the length of the ready-to-install inconor member (C) is 2m, it is possible to interconnect and use the inconor member of about 1m through the connector (J). and,

In this case, as shown in Figure 2 it is possible to maximize the reinforcing effect by introducing a separate reinforcement (補强 具) (R) on both ends of the two inner corner member (C) connected to each other.

The reinforcement (R) is roughly the same shape as removing one fitting portion 40 of the connector (C),

Also made of the fitting portion 50 and the locking portion 59,
