Abstract

The object of the present invention is to provide an upper and lower molded thin plate beads for concrete surface treatment, which are constructed to form the smoothness of upper and lower molding parts in the concrete surface treatment work.

The present invention is made of an angle-shaped (() shape of the cross-section 'b' shape, the first member 30 is formed with a plurality of irregularities 10 on one side, and made perpendicular to the first member It characterized in that it comprises a second member 40 formed integrally.

According to the present invention, when the concrete surface treatment work, it is possible to finish the upper molding line or the lower molding line smoothly by installing the upper and lower molding thin plate beads for concrete surface treatment, and reconstruct the construction work caused by the smoothness of the concrete surface. This reduces the cost of construction and enables the work to be completed more quickly.

Description

Molding sheet bead for leveling inequalities in the surface of concrete walls}

The present invention relates to upper and lower molded sheet beads used in finishing works of concrete structures, and in particular to upper and lower molded sheet beads used in finishing methods using resin spray type concrete coatings. It is about.

In general, when the surface treatment of the structure at the construction site of the concrete structure, there is a problem that the finish surface is greatly reduced because the surface of the concrete is not smooth due to the reduction of formwork precision and the use of excessive vibrators when placing concrete.

In addition, the installation of the upper molding or the lower molding was a construction method to be re-installed after the airtight construction and the baseboard construction.

In order to solve the problem of the construction method, and to form a smooth and beautiful base surface molding and mop beads were used, Figure 1 shows an example of such a conventional bead.

As shown in FIG. 1, the conventional baseboard bead is used for plaster finishing with cement mortar, and the mortar coated on the wall during finishing with cement mortar has a considerable thickness, and the beads also have a size suitable for such a thickness. Only the finishing underline was kept.

By the way, in recent years, the surface treatment work of concrete building has a new spray coating material, that is, excellent adhesiveness and crack suppression performance, and resin spray coating material that improves the smoothness of concrete surface by spraying the whole concrete surface by several millimeters. (Refer to Korean Patent Application No. 2000-16811 filed by the present applicant.) The use of such resin spray coatings is generally applied to cement coating or cement mortar coating in the concrete surface treatment work. And the benefit of not having to undercoat.

Therefore, in the finishing work using the new spray coating material as described above, it is fundamentally impossible to maintain the smoothness of the concrete wall using the thick and large sized beads as in the prior art.

Therefore, the present invention was devised to supplement the problems of the conventional beads as described above, and an object thereof is to provide upper and lower molded thin plate beads for concrete surface treatment, which can be usefully used for finishing work using resin spray coating materials. .

In order to achieve the above object, the present invention is made of an angle-shaped member having a cross-section 'b' shape, the first member formed with a plurality of irregularities on one side, and formed at right angles with the first member It characterized by having a second member formed of.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view showing the overall configuration of the upper and lower molded thin plate beads 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 comprises a first member 30, a second member 40, and an uneven portion 10. As shown in FIG.

The first member 30 has a thickness of about 1 mm or less, and a plurality of uneven parts 10 are formed at one side thereof. The second member 40 has a thickness slightly thicker than that of the first member and is integrally formed to form a right angle with the first member 30.

Now, look at the example using the present invention configured as described above applied to the concrete surface treatment construction as follows.

First, the construction of the upper molding bead, when applied as the upper molding bead, the concave-convex portion 10 of the bead according to the present invention on the molding reference line 5 ~ 10cm of the concrete wall 50 formed by pouring concrete into the formwork mold The first member 30 is attached to the wall so that the wall faces the wall, and the second member 40 is exposed. At this time, the concave-convex portion 10 is adhered to the wall 50 by cement paste, and the resinous spray coating material 20 is applied thereon. And the second member is exposed to function as a horizontal reference line during ceiling mortar construction.

Next, in the case of applying the lower molding beads, the first member 30 is attached to the wall 50 so that the uneven portion 10 faces the wall 50 in accordance with the floor mortar reference line, and the second member 40 To be exposed. Similarly, by attaching a cement paste to the uneven portion 10 to attach the first member 30 to the wall 50, and applying the resin spray coating material 20 thereon to form a smoothness of the base surface and the second member 40. ) Was exposed to serve as a horizontal baseline for floor mortars during construction.

Therefore, it is possible to efficiently finish the smoothness of the entire wall and floor and ceiling surfaces.

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 a resin spray coating having a thin film coating state, not only can smoothly finish the entire walls, floors and ceilings, but also obtains a beautiful finish. It has an excellent effect of achieving a shortening of air due to convenience.
