Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a notch material for balcony gutters used when constructing veranda gutters with concrete.

(Prior Art and Problems to be Solved) A boat-shaped piece of wood with a central taper on one side is usually used as a notch material for a balcony gutter, but the method of application is complicated. Therefore, in order for this cutout material to be used for multiple rotations, it is generally required that it be easy to handle after constructing the balcony gutter, that it is lightweight, that the installation opening 4 is easy to install, and that the installation device is stable. The present invention has been made in response to such needs.

[Means for solving problems]

The gist of the present invention is to provide a hollow cylindrical body having an inverted trapezoidal vertical cross section with a vertical surface on one side and a tapered surface on the other side, and a hollow cylindrical body that extends upward flush with the vertical side surface of the body. The rising wall is molded of a hard synthetic resin material, and the rising wall is integrally composited with a soft synthetic resin material for nailing, and the top of the rising wall is bent inward into a hook shape for use in lifting the main body. This invention resides in a notch material for a balcony gutter, characterized in that it is formed in a hook part of the balcony gutter.

(Function) The indentation material of the present invention is made of a synthetic resin material such as hard vinyl resin, and can be molded by extrusion molding, and the extrusion molded material is cut to a required length. use. During extrusion molding, a soft vinyl chloride resin is superimposed on the inside or outside of the rising wall to form a rising wall suitable for nailing, which is a composite of hard vinyl chloride resin and soft vinyl chloride.

〔Effect of the invention〕

According to the cut-out material for balcony gutters of the present invention, after the veranda formwork is erected, by nailing the rising wall on the side of the crosspieces fixed with the formwork, the cut-out material is removed so that the lower surfaces of the crosspieces and their undersides are flush with each other. It is firmly and stably set in the formwork so that it is one piece.

In addition, when dismantling the formwork after pouring veranda concrete, widen the nails mentioned above, and after dismantling the formwork, hold the top hook of the rising wall and pull it up. It can be demolded more easily and quickly than concrete, making it easy to transfer to the next construction site.

At this time, the cut-out material of the present invention has a rising wall extending on the vertical side surface of the main body flush with the side surface, and the cut-out material and the lower surface of the crosspiece are also flush with each other, so that the molded balcony gutter can be The side and bottom surfaces can be provided with raised or neat gutter without tiering.

In addition, since the indentation material of the present invention is made of a synthetic resin material such as hard vinyl chloride resin, it has excellent releasability to concrete.
Moreover, since it is made of hollow synthetic resin, it is lightweight, and there is no need for the effort and expense of applying a release agent, which is required when using conventional wood, and it is extremely advantageous in terms of the number of times and frequency of reuse.

In addition, the main body and the rising wall are an integral structure made of hard synthetic resin extending in the longitudinal direction, and since the rising wall is composited with a soft synthetic resin for nailing, combined with the material, it can be easily manufactured by extrusion molding. This is also an advantage in this respect.

〔Example〕

The present invention will be described below with reference to embodiments shown in the drawings, but these are shown for illustrative purposes and the present invention is not particularly limited thereby.

FIG. 1 is an explanatory cross-sectional view of a balcony gutter notch material, which has an inverted trapezoidal shape with one side (a) of the main body (1) being a vertical surface and the sacrum side (b) being a tapered surface.

Therefore, the upper surface (C) is naturally wider than the lower surface (d).

(2) is a rising wall that extends upward flush with the vertical side surface (a) of the main body (1), and the main body (1) and the rising wall (2) have a certain length after extrusion molding of hard vinyl chloride resin. It is a one-piece molded product that can be cut into pieces.

The top of the rising wall (2) is bent inward into a hook shape to form a hook (g) for pulling up the main body during demolding.

On the inside of the above-mentioned rising wall (2), a nailed soft vinyl chloride resin layer (e) is composited, which is similar to the main body (1).
A soft vinyl chloride resin layer is overlaid on the inside of the raised wall (2), which is formed by extrusion molding a hard vinyl chloride resin.

Next, the method of using this balcony gutter notch material is shown in Fig. 2.

(3) is the concrete that forms the walls and floor of the veranda, with formwork (4) on the outside of the wall and formwork (5) on the inside of the wall.
and concrete (3) using the formwork (6) below the floor surface.
), but before that, the beams (7) (
8), and apply the cutout material of the present invention to the inside of this crosspiece (708) so that the lower surface of the main body (1) is the same as the lower surface of the crosspiece (7), and the rising wall (2) is fixed. Drive a nail (9) into the soft vinyl chloride resin layer (e) of the rising wall (2).
) nails (9) to the crosspieces (8) through the hard PVC resin.
Insert and fix the rising wall (2) to the crosspiece (8).

In this way, the setting is completed by setting up the formwork and attaching the balcony gutter cutout material of the present invention.

After pouring concrete (3) and dismantling the formwork by handling nails (9), etc., remove the main body from the poured concrete 1 to (3) by pulling up the hooks (g), and proceed to the next step. Divert to.

Figure 3 shows a veranda with 1q of cast concrete (3), and there are no steps on the sides and bottom of the side iM (10), giving a well-finished side gutter. The top surface (C) of the main body (1) rises from the intersection corner (f) of the top surface (C) and the tapered side surface (b).
), making it convenient for troweling the top surface of veranda concrete (3°).
