Reinforcing member 20 including; is made, including, the panel support 13 of the main body 10 and the reinforcing support 23 of the reinforcing member 20 is provided with holding means 30 formed to correspond to each other It is characterized by that.

First, the corner member (IM) according to the present invention is installed in the corner portion of the formwork, especially the corner portion of the formwork when assembling the formwork panel arranged outside and inside the concrete structure such as walls or pillars when building buildings

It supports the inner corner of the concrete structure and the inner panel of the formwork.

1 and 2, in the inner member having improved durability according to the present invention, the main body 10 is

It comprises a wallpaper support 11, a panel support 13 and a receiving portion 15 formed inside the main body 10 by the wallpaper support 11 and the panel support (13).

In the main body 10 according to the present invention, the wallpaper support 11 is formed to be in contact with the corner portion of the concrete structure,

Most of the wallpaper retardation 11 is formed in orthogonal form,

In a special case, for example, when the angle of the corner portion of the concrete structure is an acute or obtuse angle, the wallpaper support 11 is also formed to form a corresponding angle to support the corner portion of the concrete structure.

In the main body 10 according to the present invention, the panel support 13 is connected to each end of the wallpaper support 11, and each panel support 13 forms a shape orthogonal to each wallpaper support 11 ,

In addition, the panel support 13 is formed to be in non-contact with each other so that each end of the panel support 13 maintains a free state.

In addition, each panel support 13 is to support the inner panel of the formwork, respectively,

In this case, a plurality of support protrusions 13a are formed on the outer surface of each panel support 13 along the longitudinal direction of the inner member IM so that the inner panel of the formwork is installed.

Formwork panels formed on both sides of the panel formed to correspond to the support protrusion 13a and coupled to the panel support 13 are provided with protrusions (not shown) corresponding to the support protrusion 13a.

When the panel support 13 and the formwork panel are connected, the binding force can be increased by connecting the panel support 13 and the formwork panel using fastening pins (not shown) and tie rods (not shown).

Furthermore, each inner edge of the main body 10 according to the present invention is provided with a reinforcement pad 17 in the longitudinal direction of the inner member (IM),

The reinforcement pad 17 has stress at each corner part when an external force is applied when each corner part of the main body 10 is formed at right angles, so that strength is weak at each corner part of the inner corner member IM. It is a configuration introduced to prevent a fatal effect on durability.

That is, the reinforcement pad 17 is formed in the form of the addition of having a certain size to each corner portion of the main body 10,

By resisting the stress concentrated at each corner portion of the main body 10, and at the same time to strengthen the strength to prevent economic loss due to breakage or damage of the inner member (IM) or loss of reliability of the product, improve the durability of the product You will have the advantage.

On the other hand, while the inconor member (IM) according to the present invention has the advantages of low cost, light weight, durability and assemblability of the price and high quality of the concrete molding surface,

In the case of using the synthetic resin material as the inner corner member (IM), it is necessary to reinforce it because it is weak in strength, and therefore, the introduction of a member for reinforcing the strength of the inner corner member (IM) is urgently required. The phosphorus reinforcing member 20 will be described in detail.

1 and 2, in the inner member IM improved in durability according to the present invention, the reinforcing member 20 is

A reinforcing supporter 23 inserted into the receiving portion 15 of the body 10 and slidingly connected to the body 21 and connected to the body 21 and arranged between the panel supporters 13; Made up of

The reinforcing member 20 reinforces the strength by supporting the main body 10.

In the reinforcing member 20 according to the present invention the body 21 is formed to correspond to the shape of the receiving portion 15 of the main body 10 is inserted into the receiving portion 15,

In addition, it is provided to be sliding along the inner wall surface of the receiving portion 15,

When the reinforcing member 20 is arranged in an appropriate number to reinforce the strength of the main body 10, it is possible to provide excellent workability by providing mobility to appropriately adjust the arrangement position of the reinforcing member 20. have.

And the reinforcing support member 23 in the reinforcing member 20 according to the present invention

Is formed in an inclined form on one side of the body 21 is located between the end of each panel support 13,

This is because when the main body 10 receives a compressive force from the outside, the end portions of the panel supports 13 are kept in a non-contact free state so that each panel support 13 is inward by a compressive force applied from the outside. Compressive deformation in the direction and thereby the applied stress is applied.

The reinforcement support 23 is arranged between the end portions of the panel support 13 so that each panel support 13 against the compressive deformation of the panel support 13 due to the compressive force applied from the outside and the resulting stress. Compression deformation and strength of the is prevented from being reduced.

On the contrary, when the main body 10 according to the present invention is subjected to an external force from another side in addition to the compressive force as described above, each panel support 13 is opened in the outward direction or the deformation of only one panel support 13 When applied stress is applied

Only the reinforcing support 23 is difficult to counteract its deformation and stress,

Therefore, the holding means 30 is introduced in the present invention to counteract such deformation and stress.

That is, the holding means 30 according to the present invention is formed so as to correspond to each other and to support the panel support 13 of the main body 10 and the reinforcement support 23 of the reinforcing member 20 to each of the panel support 13 ) Will resist outward deformation and the resulting stress.

The holding means 30 for this purpose is formed in the male or female fitting portion formed at each end of the panel support 13 of the main body 10 and the reinforcing support 23 of the reinforcing member 20, the respective fittings It comprises a female or male part formed to correspond to the part,

1 and 2, the panel support 13 is shown with a male fitting portion 31, and the reinforcing support 23 is provided with a corresponding female fitting portion 33, respectively.

In contrast, even if formed on the contrary, the original function or action of the holding means 30 is maintained as it is.

That is, the male fitting portion 31 of the panel support 13 protrudes inward, and a first locking protrusion 31a having a '┻' shape is formed.

The female engaging portion 33a of the reinforcing support 23 has a first locking groove 33a formed to correspond to the first locking projection 31a of the male fitting portion 31a.

The first locking projection 31a is inserted into the first locking groove 33a, and the reinforcing member 20 is held by the holding means 30 so that each panel support 13 is opened. This can prevent the strength from being reduced by the stress.

This means that each panel support 13 of the main body 10 according to the present invention is a holding means 30 formed on the reinforcing support 23 of the reinforcing member 20, and each panel support 13 and the reinforcing support 23. It is possible to reinforce the strength to resist deformation and stress caused by gap or compression by

In addition, when the body 10 is deformed as described above, in particular, each panel support 13 is opened.

The area of the accommodating part 15 of the main body 10 is relatively increased to loosen the coupling between the main body 10 and the reinforcing member 20, so that the reinforcing member 20 slides downward by its own weight,

This prevents the reinforcing member 20 from being displaced from the arrangement position applied for strength reinforcement of the main body 10, thereby maintaining the original purpose of introducing the reinforcing member 20, thereby improving durability of the inner corner member IM. You can do it.

Meanwhile, FIG. 3 and FIG. 4 attached show another embodiment according to the present invention.

1 and 2 has a rectangular shape of approximately 150 mm in length and 100 mm in height, so that the fitting portions formed on the panel supports 13 in the holding means 30 have protrusions. Even if it is made in the shape of the fitting part, the size of the inner member IM is large, and the space formed by the receiving part 15 of the main body 10 is large, so that it is inconvenient for a worker to put his hand into the receiving part 15 and work. It's not difficult.

However, when the inconor member IM has a length of about 100 mm and a height of about 100 mm, as shown in FIGS. 3 and 4, the main body (compared to the inconor member IM having a rectangular shape as shown in FIGS. 1 and 2). The space formed by the accommodating part 15 of 10 is relatively narrow.

Therefore, in this case, when the fitting portion 31 of the projection shape in which the fitting portion of each panel support 13 is directed inwardly is formed, the space inside the main body 10 is narrowed by that much, so that the operator is provided with the receiving portion 15. The problem is that it is inconvenient and difficult to work with hands.

In order to solve this problem, in FIG. 3 and FIG. 4, the holding means 30 has a second locking groove 31b, which is a female fitting portion 31A, formed in each panel support 13,

On the reinforcing support member 23 of the reinforcing member 20, a second locking protrusion 33b, which is a male fitting portion 33A, is formed.

In this case, the female part 31A is formed at the end face of each panel support 13 so that the workability can be improved by sufficiently securing the space occupied by the accommodating part 15 of the main body 10.

Furthermore, the body 21 of the reinforcing member 20 according to the present invention is further provided with a buffer means 25,

First, the outer wall surfaces of the body 21 of the reinforcing member 20 are formed to be spaced apart from each other, and a plurality of contact protrusions 26 are formed to contact the inner wall surfaces of the receiving portion 15.

The buffer means 25 is formed on the outer wall surface of the body 21 of the reinforcing member 20, and formed between the contact protrusions 26 and the inner wall surface of the receiving portion 15 of the main body 10; It consists of a non-contact groove 25a formed so as not to contact.

That is, when the shock absorbing means 25 is formed so that the outer wall surface of the body 21 of the reinforcing member 20 is entirely interviewed with the inner wall surface of the receiving portion 15 of the body 10.

When the impact or external force applied from the outside of the main body 10 is repeated, it is transmitted to the body 21 of the reinforcing member 20 as it is, and when the reinforcing member 20 itself does not properly absorb the impact or external force, fatigue (疲勞) ) There is a problem that breakage or cracking occurs due to the phenomenon.

Therefore, between the contact projections 26 formed in the body 21 to form a non-contact groove (25a) as a buffer means 25 to reduce the contact area,

In addition, the non-contact groove 25a absorbs and / or cushions external force or shock transmitted from each contact protrusion 26 to reinforce the strength of the reinforcing member 20 itself, thereby improving durability of the product.

In addition, the plurality of non-contact grooves 25a, which are the shock absorbing means 25, are provided with additional functions for losing weight of the reinforcing member 20, thereby obtaining a side effect of reducing materials and saving costs. .

’과 같이 형성되고,Furthermore, in the reinforcing member 20 according to the present invention, the body 21 has a cross-sectional shape of approximately 'in terms of saving material.

',

The upper portion of the cross-sectional shape is provided with an upper surface support portion, and the wing portion formed to face in the lower direction on both ends of the upper surface support portion.

However, each wing of the body 21 is not provided with a separate support at the lower end thereof has a disadvantage in that it is weak in strength due to the deformation or stress applied by external force or impact applied from both sides.

Therefore, in order to solve the above disadvantages, a plurality of reinforcing ribs 27 for supporting the wing of the body 21 are provided.

The reinforcing ribs 27 are connected to the inner wall surface of the wing portion so as to intersect with each other in a horizontal direction or a vertical direction, or take a structure for reinforcing the reinforcement member 20 by supporting each wing portion.

Furthermore, the body 21 according to the present invention is further provided with a plurality of through holes 29 in the upper surface support portion in the cross-sectional shape,

This is because when concrete is injected into the formwork when concrete penetrates from the inner corner member (IM) to the receiving portion 15 of the main body 10, the concrete piles up and adheres to the upper surface of the reinforcing member 20 arranged in the main body 10. Or

Alternatively, the concrete penetrates into and adheres between the inner wall surface of the accommodating part 15 of the main body 10 and the outer wall surface of the body 21 of the reinforcing member 20, and thus concrete serves as a bonding role.

In this case, the task of separating the reinforcing member 20 from the main body 10 or the operation for adjusting the arrangement position of the reinforcing member 20 in order to recycle the reinforcing member 20 is difficult,

In addition, there is an inconvenience that one by one to remove the concrete fixed to the reinforcing member 20.

Therefore, the concrete that penetrates the upper surface supporting portion of the body 21 from the reinforcing member 20 to form the singular or plural through holes 29 and penetrates into the corner member IM passes through the through holes 29 and is below. Can be discharged in the direction of

To facilitate the separation and position adjustment work for recycling the reinforcing member 20,

In addition, unnecessary maintenance work can be eliminated to increase work efficiency.

Meanwhile, in FIG. 5, an implementation example of continuously connecting the main body 10 of the inconor member IM having a predetermined length by the reinforcing member 20 is illustrated.

It is formed to the thickness of the reinforcing member 20 is approximately twice the thickness of the reinforcing member 20 shown in Figures 1 to 4

The upper part corresponding to half of the reinforcing member 20 is inserted into the lower part of the main body 10 arranged at the top, and the lower part corresponding to the other half of the reinforcing member 20 is arranged at the lower part of the main body 10. Inserted into the upper portion of the) serves as a connector for connecting the main body 10 arranged in the upper and lower.

In this case, the reinforcing support member 23 and the holding means 30 of the reinforcing member 20 support the adjacent end portions of the respective main bodies 10, and thus, each of the main bodies 10 together with the role of the coupling unit as described above. At the same time, it is possible to reinforce the strength of the connecting portion.

In the above description with reference to the accompanying drawings, the present invention has been described with a focus on a specific shape and direction in the durability of the improved inner member, the present invention can be variously modified and changed by those skilled in the art, such variations and modifications of the present invention It should be interpreted as being included in the scope of rights.
