Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an embedded fixed tree used for plastering work, particularly for gable of a building and finishing of a curtain plate part.

[Conventional technology]

Generally, in plastering work for buildings, the work of applying a wall material to the surface of the skeleton with a trowel is mainly performed, but the corner edge of the skeleton, for example, a corner part of the room, a window, etc. It is well known that it is very difficult to apply a wall material only with a trowel to a salient portion between an opening and a wall surface, and a great deal of skill and labor is required.

Therefore, in order to eliminate such inconvenience,
Japanese Unexamined Patent Publication No. 141 discloses an embedded molding material (embedded fixed tree) that is embedded in the wall material of the corner edge portion, and it is proposed to improve workability in the corner edge portion by the embedded molding material. . This embedded mold member is provided with two contact plates that form a required angle, and a corner cutting piece that projects outward from the coupling portion of these contact plates. By aligning the surface of the wall material with the edge portion of the corner cut piece in a state of being embedded in, the wall coating work on the corner edge portion can be efficiently performed.

[Problems to be solved by the device]

The embedded mold member is integrally formed of a hard synthetic resin material or a metal material as a whole, and the angle formed by the two contact plates is fixed. On the other hand, most of the corner edges of buildings etc. in which this embedded type material is used have an angle of about 90 °, but at special corner edges, such as gables and curtain boards, the walls form The angle is out of 90 °. Therefore, in order to use the embedding die material for corner edges having such various angles, the embedding member having a shape corresponding to the angle of each corner edge must be individually manufactured each time. However, there is a problem in that it lacks versatility and increases cost.

In view of such circumstances, an object of the present invention is to provide a plastering material for plastering which can always easily form a good wall surface regardless of the angle of the applied corner edge.

[Means for Solving the Problems]

The present invention relates to a plastering embedded tree for plastering, which includes a pair of contact plates that are connected to each other to form a predetermined angle, and a corner cutting piece that projects outward from the connection part of the contact plates. Only the base part of the plate is made of soft plastic, and the other part is made of hard plastic.

[Action]

According to the above configuration, by applying the touch plate on the side where the base portion is not formed of soft plastic to the body, and bending and deforming only the other touch plate at the soft plastic portion with reference to this touch plate, corner cutting is performed. With the position of the piece fixed, the angle formed between the contact plates can be matched to the shape of the corner edge of the skeleton, and in this state the embedded fixed tree can be embedded in the wall material without any problem.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS.

The embedded plastering tree for plastering shown here has a shape that extends in the depth direction of FIG. 1 as a whole, and includes two contact plates 1 and 2 that are connected to each other, and a connection portion 3 of these contact plates 1 and 2. A corner cutting piece 4 protruding outward (obliquely upward right in FIG. 1) is provided, and an approximately saw-toothed concave-convex portion is formed on the entire surface for good adhesion with a wall material. There is.

This plastered wood for plastering is integrally extruded from plastic such as polyvinyl chloride. Specifically, one base plate 2a of the contact plate 2 is made of soft plastic, and the other part is made of hard plastic. Has been formed. Therefore, the base 2a of the contact plate 2 can be bent and deformed, and the other parts are hardly deformed.

The embedded fixed tree in this embodiment is formed such that the forming angles of both contact plates 1 and 2 are 90 ° in a free state in which no external force is applied, and the soft plastic part (the base 2
The region size 1 (FIG. 1) of the soft plastic is set such that the angle changes inward and outward to a predetermined angle due to bending deformation of (a) (two-dot chain line in FIG. 1).
For example, when the thickness of the contact plate 2 is about 1.5 mm, the deformation area of the above angle can be expanded to about 80 ° to 100 ° by setting the dimension 1 to about 5 mm.

Next, how to use this embedded constant tree will be described.

First, as shown in FIG. 3 (a), at the corner edge of the building frame 5 of the building, the contact plate 1 is brought into contact with one side thereof and fixed with a tacker or the like, and then the remaining contact plate 2 is The base 2a is bent and brought into contact with the other side, and similarly fixed with a tacker or the like.
At this time, since the angle formed by the two contact plates 1, 2 changes due to the bending deformation of the base 2a of the contact plate 2 as described above, the angle of the corner edge of the skeleton 5 is not 90 ° as shown in the figure. Also in this case, both contact plates 1 and 2 can be fixed to the surface of the frame 5 without any inconvenience.

Next, the wall material 6 is applied from above the embedded solid wood, and the outer surface 6a of the wall material 6 is evenly leveled by a trowel or the like while being aligned with the free edge portion 4a of the corner cutting piece 4. . As a result, as shown in FIG. 3 (b), a good wall surface can be easily formed in a state in which the embedded fixed tree is embedded in the wall material 6.

Even if the base portions 1a and 2a of both contact plates 1 and 2 are made of soft plastic as shown in FIG.
It is possible to arbitrarily adjust the angle formed by
As in the above-described embodiment, if the one contact plate 1 is formed of hard plastic over the entire area so as not to be bent and deformed, the position of the corner cutting piece 4 is determined by using this contact plate 1 as a reference. It is possible to stably perform the fixing work to the skeleton 5 by adjusting only the angle between the contact plates 1 and 2 while fixing.

In addition to directly fixing the embedded solid wood to the skeleton with a tacker or the like as described above, for example, the surface of the skeleton 5 may be pre-coated with the wall material 6 or an adhesive may be applied to the wall material 6 or the adhesive. After fixing the embedded fixed tree on the surface, the wall material 6 may be overcoated from above.

[Effect of device]

As described above, according to the present invention, in an embedded plastering tree for plastering, which includes a contact plate and a corner cut piece that are connected to each other, only one base of the one contact plate is made of soft plastic so that it can be bent and deformed. Since it is formed of hard plastic, the angle between the touch plate and the corner cut piece on the side where the base is not formed of soft plastic is fixed, while the other soft plate is made of soft plastic. By bending and deforming, the angle formed by both contact plates can be changed by the bending deformation while the position of the corner cutting piece is stably maintained. Thereby, regardless of the angle of the corner edge of the skeleton, the embedded fixed tree can be embedded in the wall material in a stable operation without inconvenience, and a good wall surface can be easily formed.
