In order to reduce the amount of material consumption by making the thickness of the inner corner member as thin as possible, the main body is in contact with the outer surface of the structural contact portion and the panel contact portion of the inner corner member to prevent deformation of the inner corner member even when concrete is put into the assembled formwork; Providing a reinforcement having a engaging projection formed in the corresponding position of the main body so that it can be fitted into the fastening hole of the panel contact portion

The purpose of the present invention is to make it possible to reliably reinforce the bearing force against the pressure acting in the outward direction when concrete is put into the assembled formwork even in the situation where the rigidity of the inner member itself is inferior using general synthetic resin or recycled synthetic resin.

In addition, the present invention is because the main support portion and the auxiliary support portion of the main body is made of a plate-shaped synthetic resin, the material consumption is small, each support portion is connected by a separate reinforcement, inconor member that can meet both low cost, light weight, durability To provide a reinforcement for the purpose.

Furthermore, an object of the present invention is to provide a reinforcement tool for an inner corner member having an inclined portion formed on the engaging projection so that the engaging protrusion easily moves on the outer surface of the auxiliary powder of the inner corner member to be easily coupled to a desired position. It is done.

In order to achieve the above object, the reinforcement for the formwork inconor member according to the present invention has a height corresponding to the height of the concrete structure to be constructed and has an angle corresponding to the angle of the concrete structure inconor portion to be constructed. A structural contact portion consisting of two main powders interconnected at the bend portion, and

It is connected to form a secondary bent portion at each main powder side end of the structural contact portion, consisting of two auxiliary powders that are in contact with the general panel, the fastening hole is inserted into the fastening pin for binding with the general panel Is arranged on the outer side of the inner corner member including the formed panel contact,

A main body including a main support part in contact with an outer surface of the main body of the inner member and an auxiliary support part in contact with an outer surface of the auxiliary powder; And

Coupling protrusion formed in the main support portion to be fitted to the fastening hole formed in the auxiliary powder of the inner member

It is made, including.

In addition, the reinforcement for the formwork inconor member according to the present invention to ensure a low cost, light and durable enough

It is preferable that the main body is further provided with a reinforcing bar which interconnects the main supporting part and the auxiliary supporting part.

In addition, the present invention to facilitate the assembly and assembly with the inner corner member

Preferably, the coupling protrusion has an inclined portion so as to easily move on the outer surface of the auxiliary powder of the incone member.

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 reinforcement tool R for the formwork corner 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',

When the concrete structure (W) to be molded as shown in the wall is determined up and down based on the direction of gravity.

As shown in Figure 1, the formwork inconor member (C) used in the reinforcement (R) according to the present invention can be injection molded with a synthetic resin material and the two forming a contact portion 10 in contact with the concrete structure (W), in particular, the wall The main powders are interconnected in a state of being bent at an angle (90 degrees in the drawing) from the central main bent portion 13,

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 ( Example: a height of 1m or 0.5m).

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 deformed to form a sparse auxiliary powder is coupled at regular intervals,

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 guarantee a space that can be increased, thereby increasing work convenience.

When the concrete member is put in a state in which the inner corner member C is connected and assembled using another panel 30, 30A, a fastening pin 35, a tie rod 37, or the like, 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 place, the general panel and the inconor connection part do not come into close contact with each other, resulting in concrete leakage.

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.

It is preferable that the locking projection of the corner member C is formed to intersect with the inner and outer protrusions and the outer and inner sides, 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 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 narrowed in the width of the end portion so as to be easily inserted in the first time, and then detached from the fastening hole. Head portion 35a for preventing the, and has an 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 2, 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 bar 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 easily opened or narrowed to each other. It is desirable to introduce an incision to make

First, as shown in (a) and (b) of FIG. 2, the 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 reinforcement ribs 13A and 23A which are thicker than the other parts of the inconor member on 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 FIG. ) (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. 2 (c), the cutout portion 25 is an auxiliary bent portion that forms a predetermined angle (eg, 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 grooves open 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. 2 (d) is formed at the major bent portion 13 between two main powders 11A and 11B, which is a cutout that forms the core of the present invention.

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.

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

Next will be described the reinforcement (R) for the inner corner member (C) according to the present invention.

As shown in Figure 1, the reinforcement (R) is composed of a main body 40 and the engaging projection 49,

The main body 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),

The stacking protrusion 49 is formed in the main body 40 auxiliary supporting portions 43A and 43B so as to be fitted into the fastening holes 22 formed in the auxiliary powders 21A and 21B of the inner member C.

The height of the main body 40 may vary, and the coupling protrusion 49 should be formed in accordance with the shape, size, and arrangement position of the fastening hole 22 formed in the auxiliary member auxiliary powder.

Basically, since the fastening hole 22 of the auxiliary powder is for connection with the general panel 30, the coupling protrusion 49 of the reinforcing hole R is formed of both auxiliary powders 21A and 21B located at the same height. Two fastening holes 22 are formed so that two can be fitted,

The height of the main body 40 is about the height that the coupling protrusion 49 is located at the same height may be suitable for utilizing the original function of the fastening hole (22).

In FIG. 1, the supporting bases 41A and 41B of the reinforcement R main body 40 and the auxiliary supporting parts 43A and 43B are interconnected at each end.

In addition, the auxiliary support 43A (43B) is mutually connected to each other at the end by a separate joint 45

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 reinforcing tool R according to the present invention, the main body 40 is further provided with a reinforcing bar 47 for interconnecting the supporting parts 41A and 41B and the auxiliary supporting parts 43A and 43B.

By reducing the material consumption, it is possible to increase the weight and durability at the same time while providing the lowest cost product.

The shape of these reinforcements can vary,

On the other hand, due to the introduction of the reinforcement bar, it is possible to implement the reinforcement of the form connected through the reinforcement without the interconnection between the main support and the auxiliary support, even the joint.

Subsequently, in the reinforcing hole R according to the present invention, the coupling protrusion 49 may have an inclined portion 49a so as to easily move on the outer surface of the auxiliary powders 21A and 21B of the inner member C. Together,

In FIG. 1, the coupling protrusion 49 facilitates arranging the reinforcement sphere at a desired height of the inner corner member C when the reinforcing member R is introduced from the upper side to the lower side with respect to the inner corner member C. And

If necessary, the inclined portion may be formed in an opposite direction.

Hereinafter, look at the form assembly process using the reinforcement (R) and the formwork corner member (C) according to the present invention described above.

First, as shown in FIG. 1, the general panel, in particular the Euroform panel 30, is left and right and / or up and down by using the fastening pin 35 inserted into the fastening hole 32 of the rim member 31 of each panel. When connecting to reach the part to form a corner to connect and assembly the inner member (C),

In this case, the reinforcing holes R of the present invention may be introduced from the upper portion to the lower portion of the inner corner member C, and the inner corner member C may have some elasticity due to the synthetic resin material characteristics, and the cutout portion described above ( 15) (25) increases the elastic force

If you slightly push the reinforcement (R) while spreading the structure contact portion 10 main powder (11A) (11B) and the panel contact portion 20 of the auxiliary powder (21A) (21B) of the inner corner member (C) slightly Avoiding the coupling protrusion 49 is coupled to the position of the ball 22
