Description

[Detailed explanation of the idea] This invention relates to a corner constant.

A corner ruler is a long ruler that is used to create a beautiful finish on the inside surface of a window that touches the sash when installing a sash into a building and applying mortar to the surrounding exterior walls.

This ruler is attached to a post or stud around the sash, and after mortar is applied, the ruler is used by being partially embedded in the mortar without removing it.

Corner rulers with various structures are already known.

For example, Utility Model Publication No. 48-38286 and Utility Model Number 53-3
All of the 9395 publications introduce corner constant rules.

However, in all of these corner rulers, the board and side plate are orthogonally crossed to form a long body with an L-shaped cross section, and a board protrusion and a side plate protrusion are attached to the tips of the board and side plate, respectively. It has a structure in which it extends along the longitudinal direction and stands up inward.

The above-mentioned known corner ruler has a drawback that when the wall thickness is reduced in proportion to the width, the angle between the L-shaped substrate and the side plate opens due to the application pressure of the mortar.

As a result, the side plates, which were supposed to stand upright from the sash surface, were inclined to the sash surface, resulting in poor mortar finish.

In addition, there have been a number of complaints that known corner rulers are easily twisted and deform when exposed to direct sunlight or in poor storage conditions, rendering them useless.

Therefore, it was necessary to improve this drawback.

This invention was made in an attempt to improve these drawbacks.

The gist of this invention is to insert a brace piece between the base plate and the side plate in the above-mentioned known device.

In that case, we considered that the corner constants would be made by extrusion molding using synthetic resin as a material, and the brace pieces would not be composed of one flat piece, but would be composed of pieces bent in a dogleg shape. The device is characterized in that one piece of the dogleg-shaped bent body is oriented parallel to the base plate or the side plate and is attached integrally thereto.

Further, the main feature is that the inner surface of the tip of the side plate protrusion attached to the tip of the side plate is inclined inward by 5 to 15 degrees from a plane parallel to the plane of the substrate.

That is, in this invention, the board and the side plate are orthogonal to each other to form an elongated body with an L-shaped cross section, a board protrusion and a side plate protrusion are attached to the tips of the board and the side plate, respectively, and each protrusion is extended along the longitudinal direction. At the same time, a reinforcing plate whose cross section is bent in a dogleg shape is inserted between the board and the side plate at the corner ruler that stands up inward, and one piece of the doglegged bent body is inserted. This invention relates to a corner ruler made of synthetic resin that is parallel to the substrate or side plate, and the inner surface of the tip of the side plate protrusion is inclined 5° to 15° inward from the plane parallel to the substrate.

An example of the implementation of this invention will be described below with reference to the drawings.

FIG. 1 is a partially cutaway perspective view of a corner ruler according to this invention.

FIG. 2 is a cross-sectional view of a building near a pillar, showing how the corner ruler according to this invention is used.

In Fig. 1, 1 is a side plate, 2 is a base plate, 3 is an upright reinforcing plate, 4 is an inclined reinforcing plate, 5 is a base protrusion, 6 is a side plate protrusion, 7 is an inner surface of the side plate protrusion, 8 is an upper protrusion, and 9 is a Tip slope, 10
is the connection part between the upright reinforcing plate 3 and the inclined reinforcing plate 4, and 11
is a locking plate.

Of these, the side plate 12 and the substrate 2 are orthogonal to each other to form an elongated body with an L-shaped cross section, and a substrate protrusion 5 and a side plate protrusion 6 are attached to the tips of the substrate 2 and the side plate 1, respectively. At both ends, protrusions are formed that stand up inward.

Further, the upright reinforcing plate 3 and the inclined reinforcing plate 4 are bent at the connecting portion 10 to form a folded body having a dogleg shape in cross section, thereby forming a braced reinforcing plate.

Among them, the outer surface of the upright reinforcing plate 3 is parallel to the outer surface of the side plate 1.

The inner surface 7 of the side plate protrusion 6 is inclined inward by an angle α than a plane parallel to the surface of the substrate 2, and α is within a range of 10±5°.

In addition, the surface connecting the tips of the upper projection 8 and the side plate projection 6 is
The tip slope 9 forms an obtuse angle β with respect to the substrate 2 and the plane, and the obtuse angle β is within the range of 135±15°.

Further, it is desirable to attach a locking plate 11 that projects diagonally outward from the connecting portion 10 along the longitudinal direction.

Further, it is desirable that the locking plate 11 has a thick tip.

It is desirable that the position 12 where the upright reinforcing plate 3 contacts the substrate 2 be within a range of half to half the width W of the substrate 2, as measured from the side edge of the substrate 2 closer to the side plate 1.

Further, the position 13 where the inclined reinforcing plate 4 contacts the side plate 1 is preferably within a range of half to ÷ of the width H of the side plate 1, as measured from the side edge of the side plate 1 near the substrate 2.

Furthermore, the angle γ between the inclined reinforcing plate 4 and a plane parallel to the substrate 2 is
is preferably within the range of 45±15°.

In this way, the effect of the reinforcing plate is fully exhibited.

In the example shown in FIG. 1, the upright reinforcing plate 3 is made parallel to the side plate 1, but depending on the ruler, a part of the reinforcing plate may be made parallel to the base plate 2.

Furthermore, in an extreme case, the inclined reinforcing plate 4 shown in FIG. 1 may be made parallel to the substrate 2.

The ruler of this invention is an elongated body having the above-mentioned cross-sectional shape and made of hard resin.

As the hard resin, it is desirable to use hard vinyl chloride resin, but other thermoplastic resins can also be used.

To make the ruler of this invention from synthetic resin, extrusion molding must be used.

The ruler of this invention is used as shown in FIG.

In Fig. 2, a is a column, b is a sash, C is a lower plate, d is a lath, e is a corner ruler according to this invention, and f is mortar for an outer wall.

The ruler e of this invention is located on the outside of a building and is fixed by nailing or the like around a sash b attached to a pillar a.

A lath d is fixed around the ruler for applying mortar.

Mortar is applied to the top of the lath d to the full height of the tip of the upper protrusion 8 of the ruler e, leaving the ruler e as the outer wall of the building.

Since the ruler of this invention is equipped with reinforcing plates 3 and 4, when applying mortar as described above, even if a certain amount of strong pressure is applied to the mortar, the side plate 1 is not perpendicular to the base plate 2. It won't break down.

Further, since the reinforcing plates 3 and 4 are provided, there is less twisting in the longitudinal direction, and less deformation due to direct sunlight or storage conditions.

Therefore, the mortar has a beautiful finish.

Furthermore, in order to make the ruler of this invention, extrusion molding is used, and during extrusion molding, the outer surface of the side plate 1 and the outer surface of the upright reinforcing plate 3 are parallel to each other, and the width is considerably large. Because it has , the two sides can be sandwiched between a set of rolls and removed from the extruder.

Therefore, it is easy to take off and therefore easy to manufacture.

In addition, since the inner surface 7 of the side plate protrusion is inclined inward by α than the plane parallel to the substrate, and α is a small angle of about 5° to 15°, mortar can also be applied to the surface of the inner surface 7. Easy to push.

In this respect, the ruler of this invention is superior to one in which the inner surface 7 is provided with a projection that projects further downward.

Moreover, since it is inclined inward, the side plate protrusions 6 are locked by the mortar after the mortar hardens, so that the ruler is strongly fixed to the mortar.

The ruler of this invention has such advantages.

When the upper protrusion 8 is provided, the tip of the upper protrusion can be used to wipe the application iron when applying mortar, resulting in a beautiful finish.
