Description

In-corner sheet bead for leveling inequalities in the surface of concrete walls}

The present invention relates to a wall inconor bead used for the finishing of concrete structures, and more particularly to a thin plate inconor thin bead used in the construction method using the resin spray type concrete surface treatment paint finish.

In general, in the case of finishing the inconor surface of the structure at the construction site of the concrete structure, there is a problem in that the surface of the concrete is not smoothed due to the reduction of formwork precision and the use of an excessive vibrator when placing the concrete, which greatly reduces the finish.

In addition, when the formwork is separated after the concrete is placed and the wall inconner is installed, the surface treatment is carried out by cement coating with a width of about 10 cm around the formwork joint. It is using construction method to finish with cement paste in surface treatment work.

In order to solve the cumbersome problem of the finishing construction method, when finishing the inconor part of the concrete wall by cement paste, the inconor bead is used to accurately and beautifully construct the face angle, and FIG. 1 is one example of the conventional inconor bead. It is shown.

Conventional inconor beads as shown in Figure 1 is used for the finishing work using cement mortar, the thickness of the mortar coated on the concrete surface during the finishing work using cement mortar is usually 3 ~ 4cm and has a predetermined size in consideration of this thickness.

Since the conventional bead is designed for multi-purpose, it is difficult to apply the conventional bead to the inner corner because the corner angle does not come out properly when the corner is applied or the bead itself has a predetermined thickness and size.

However, in recent years, the surface treatment work of concrete buildings has a new spray coating material, that is, excellent adhesiveness and crack suppression performance, as well as resin spray type to improve the smoothness of the concrete surface by spraying the entire concrete surface by 1 ~ 3mm. A coating material is used. (Refer to Korean Patent Application No. 2000-16811 filed by the applicant)

The use of such resin spray coating material provides the advantage of not having to perform the cement coating or cement mortar over and under coating in the concrete surface treatment.

Therefore, in the finishing work using the new spray coating material as described above, it is not only fundamentally impossible to maintain the smoothness of the corners using a thick bead as in the prior art, but also focuses only on the formation of the corner lines. There is a problem that the configuration for improving the smoothness of both sides is not provided.

Therefore, the present invention was devised to supplement the problems of the conventional beads as described above, and can be usefully used for finishing work using resin spray coating, and can improve not only the corner angle but also the smoothness of both sides of the corners. The purpose is to provide a thin corner bead configured.

In order to achieve the above object, the present invention, the cross-section is formed integrally at right angles to form an angle-shaped material of the 'b' shape, the first surface of the inner surface of the first and second members exposed as the corner of the corner wall It is integrally extended while being bent at a right angle twice from each end of the first and second members, the outer surface of the extended end is characterized by consisting of the third and fourth members are formed with a plurality of irregularities.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 2 or below.

Figure 2 is a perspective view showing the overall configuration of the inner bead according to the present invention, Figure 3 is a cross-sectional view of Figure 2, Figure 4 is an application state diagram of the present invention.

As shown in FIG. 2 and FIG. 3, the present invention provides a first member 31 and a second member 32 for forming an inner corner of a corner wall, and a third member 41 and a third fixed to the corner wall. It consists of four members 42 and the corner angle 20 which forms an inconor angle.

The first member 31 has a thickness of about 2 to 3 cm and is formed of a straight portion to form an angle of the corner portion. The second member 32 has the same thickness as the first member 31 and is integrally formed to form a right angle with the first member 31, and is similarly formed as a straight portion. The first member 31 and the second member are similarly formed. The inner surface of which (32) forms a right angle forms an inconor angle.

The third member 41 is formed to extend from the end of the first member 31, a plurality of uneven parts 10 are formed to extend in the shape bent twice so as to be pressed against the wall on the outside. In addition, the fourth member 42 is bent twice from the second member 32 in the same shape as the third member 41 to extend.

The irregularities formed on the outer surfaces of the third and fourth members 41 and 42 are formed to be firmly attached to and fixed to the concrete wall inner corner part 40 through cement paste, and the first member 31 and the second member. The inner perpendicular surface where (32) meets is exposed to form an inconor angle, and functions as a baseline to which concrete coating material is applied.

The inner corner 20 is formed inside the contact portion of the first member 31 and the second member 32 to match the smoothness of the wall plane.

Figure 3 shows a cross-sectional view of the inner bead, Figure 4 shows a state in which the inner corner is applied to the concrete corner wall.

Now, when the present invention configured as described above is described an example applied to the finishing work as follows.

As shown in FIG. 4, the present invention is attached to the inner corner portion of the concrete wall formed by pouring concrete into a formwork, and includes a third member 41 and a fourth member contacting the concrete wall inner corner 40. The outer surface of 42 is attached and fixed through cement paste. And the resin spray coating 30 described above is applied to the inner bead according to the present invention attached to this, wherein the inner surface of the first member 31 and the second member 32 to form the corner angle (20) It is applied to be exposed to function as a corner of the inner wall.

When the resin spray coating material 30 is applied to expose the inner surfaces of the first and second members 31 and 32 of the thin plate inner corner attached, the corner corner of the wall can be cleanly finished, and the corner angle is smooth. It is possible to quickly finish the inner corner of the concrete wall.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

As described above, according to the present invention, when the concrete surface treatment construction using the resin spray coating material having a thin film coating state, not only the corner angle and corner lines of the wall can be precisely constructed but also the beautiful finish can be obtained. It has an excellent effect of achieving a shortening.
