Description

[Detailed description of the invention] The present invention relates to an embedded ruler for a protruding corner wall in plastering work.

Embedded rulers are often used to draw out the corners and straight lines of projecting corner walls in Chiksen plastering work. This type of built-in ruler is installed across the corner edge of the building structure] Shape-color straddle rulers are known as straddle fittings that protrude from the corners of the channel to form a roughly Y-shape. .

The above-mentioned embedded ruler requires work to straddle the building surface using a form-color straddling channel before painting the wall, but with nailed etc. It is difficult to match the edge accurately with the leveling thread, and it also causes bending, so in general, mortar is applied to the corner edge of the structure to a certain thickness and glued to the soil. One possible method is to hold the mortar in the straddling channel and press it against the corner of the wall of the building frame to achieve straddling installation.

That is, by pressing the corner spanning channel of the shape ] against the corner of the wall, mortar is poured out from the many mortar joint holes drilled in the corner spanning channel of the ] shape, and a predetermined thickness is formed on the inner surface of the corner spanning channel of the shape ]. A mortar layer is formed to straddle the embedded ruler and set the amount of protrusion of the angular ruler.

Accordingly, the present invention provides a method of -1- providing a large number of mortar joint holes in the square spanning channel of the shape of ] of the embedded ruler described above, and extending the entire length of the square spanning channel of the shape of ] to the inner surface near the end member of the same channel. By providing mortar holding ribs that protrude to the
Between both hugging ribs, the mortar between the corner spanning channel of the [shaped] shape and the left and right corner edges of the wall corner is well held, and while promoting elongation within the corner spanning channel of the ] shape, the mortar flows into the mortar joining hole. By pouring out the ruler, it is possible to stably straddle the ruler using mortar as an adhesive medium, and to properly set the shape of the adhesive mortar layer and the height of the angular ruler part.

Examples of the embedded ruler will be described below with reference to the drawings.

In the figure, reference numeral 1 shows an example of the shape-embedded ruler, and reference numeral 2 visually shows the corner of the protruding corner wall on which the shape-embedded ruler 1 is mounted. Usually, in wooden buildings, the walls to be plastered are prepared with waterproof paper or a net to connect the wall materials as a base.

For straddling, the embedded ruler l is the left and right corner edges 2a, 2 of the projecting corner wall 2.
It consists of a square straddling channel la portion which is fitted over the channel la, and an angular ruler portion ib which projects longitudinally from the corner or near the corner of the channel la. The protrusion of the ruler portion 1b and IIJ of the corner spanning channel la are determined depending on the implementation. Corner straddle channel 1a
Depending on the implementation, one side of the attachment plates on the left and right sides should be made longer and the other shorter.

Holes 1 for connecting mortar are provided on the surfaces of the ruler portion 1a and the square spanning channel 1a, especially on the surface of the square spanning channel 1a.
Drill c. The hole may be a slotted hole, a round hole, etc., and the shape does not matter.

FIG. 3 shows a hole 1c for connecting mortar to the surface of the embedded ruler 1 as an optimal form for carrying out the present invention, as well as a connecting rib ld.
A beautiful soldering iron rib 1 is attached to the top edge of the ruler part lb.
Provide e.

Furthermore, mortar enclosing ribs if (including protrusions) are provided inside both ends or near both ends of the shaped channel la.

The mortar holding rib 1f is preferably as shown in FIGS. 2 and 3.
As shown in the figure] the angle formed by the shape and color spanning channel 1a with each attachment plate is smaller than 90 degrees.

Each of the above-mentioned constituent parts 1d and le will be added depending on the implementation.For the above-mentioned straddling, use the embedded ruler 1, and connect the corner straddling channel la to the left and right corner edges 2a of the projecting corner wall 2, 2a, and protrude the ruler part tb along the corner of the protruding corner wall 2. Paint the left and right walls of the protruding corner wall 2 using the top edge of the ruler part 1b as a reference, and then apply the ruler l. While embedding, corner and straight lines are performed.

FIGS. 1A, B, and C sequentially show a method for mounting the embedded ruler 1 astride. As shown in FIG. 1A, when the shape ruler 1 is straddled to the protruding corner wall 2, mortar is filled and held in the shape and color straddle channel la, as shown in FIG. 1A. As described above, the corner spanning channel la has an elongated gutter shape that is approximately aligned with the corner of the projecting corner wall 2, and has the mortar holding ribs if at both ends, as shown in FIG. By laying the channels horizontally and filling them one after another, a sufficient and appropriate amount of mortar can be held evenly over substantially the entire length of the channel la, and filling is easy and there is no fear of the mortar falling off.

A ruler 1 holding the mortar 3 prepared as described above along its entire length is used to move the left and right corner edges 2a of the projecting corner wall 2 as shown in FIG. 1B. and then press the shape-and-color spanning channel la toward the corner to apply compressive force to the mortar 3 held inside the channel.

Mortar 3 responds to this compressive force by forming mortar holding ribs i.
Inner surface and left and right corner edge surfaces 2 of the corner spanning channel between f and if
a, and in this stretching, the corner spanning channel 1a
inner surface and left and right corner edge surfaces 2a.

2a, a mortar layer 3' of a predetermined thickness is formed. This mortar layer 3' includes a corner spanning channel la, a corner edge surface 2a,
The ruler 1b functions as an adhesive medium between the edges 2a and is attached to the corner edges 2a, 2a, and causes the ruler portion 1b to protrude toward the front of the corner.

At the same time, by increasing the thickness of the mortar layer 3' in accordance with the amount of compression of the mortar 3 described above, the ruler portion 1b is straddled so as to have a predetermined protruding height that matches the thickness of the wall coating.

Apply mortar in advance to a uniform layer thickness on the corner edge surface 2a,
Also in the method of pressing with a ruler, the mortar described in item 1 is effectively encouraged to stretch at the corner edge surface 2a between the mortar holding ribs if, if.

As the mortar 3 is compressed by the shape-color spanning channel 1a, the mortar joint hole IC is sufficiently connected to the deceased IC, which is a part of the stretched mortar 3, of the corner edges 2a, 2a between the mortar enclosing lips If, If. Functions as an escape hole (compressive force absorption hole) for the mortar 3 during extrusion and compression, setting the thickness of the mortar layer 3', adjusting the protrusion height of the ruler portion 1b, and stabilizing the corner edges 2a, 2a. Adhesion can be performed accurately. In the figure, 3a shows the mortar extruded from the hole by the compression described above.

- As shown in FIG. 1C, the ruler portion 1b is mounted across the wall at a predetermined protruding height that matches the thickness of the wall coating by increasing the thickness of the mortar layer 3' in accordance with the amount of compression as described above. Then, as shown in the first diagram, E and F, the wall is painted using the ruler part ib as a reference.

Referring to this wall painting process, as shown in the first diagram, the mortar 4a, 4a] completely hides the shape and color spanning channel 1a, and also covers the top edge of the ruler part lb. Apply cover coat. In the figure, 4b indicates an overcoat portion that covers the beautiful soldering iron ribs formed on the top edge of the ruler.

Next, as shown in FIG. 1E, the extruded portion 4b' of the overcoat portion 4b of the top edge of the ruler is cut off with the tip of the iron using the soldering rib 1e as a reference, and then the area of the ironing rib 1 is cut off. Press down and make it flat and perpendicular.

More preferably, while lightly smoothing the surface of the applied mortar 4a, the flax (other than mortar sand) is drawn to the top edge of the ruler part ib, or to the surface side of the soldering iron rib le in the embodiment, to complete the corner finishing. do. By adding this process of drawing the flax, the corner finish becomes even more beautiful, and in addition, the thin layer covering the top edge of the ruler part 1b becomes stronger after hardening, which prevents peeling from the same place. Prevent cracking.

As explained above, the embedded ruler for a projecting corner wall according to the present invention is used when installing a corner spanning channel across a wall corner using mortar as an adhesive medium, when the mortar is attached to the mortar at the end of the corner spanning channel. It is well extended to the corner edge surface 2a between the holding ribs and the inner surface of the channel, and by this stretching, a mortar layer of a predetermined thickness is evenly and reliably formed between the inner surface of the spanning channel and the corner edge surface 2a. As a result, the embedded ruler can be stably attached and the ruler portion can be set at an appropriate height.

Moreover, no nests are formed inside the channel. Therefore, during curing, there will be no sinkage or cracks caused by bending of the ruler.

Mortar is also prevented from falling, eliminating wasteful use of mortar and the hassle of cleaning after milling.

Furthermore, since the strength of the embedded ruler can be strengthened and stabilized, it is possible to prevent the ruler from peeling off or falling off during subsequent wall painting work.
