Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to an eaves drainage material that is installed between the upper part of each eave attached to the wall of a building and the wall material to ensure drainage.

(Prior art) Conventionally, when applying mortar to the outer wall of a land eave or directly attached eave, the mortar was usually joined directly to the upper roof iron plate of the eave body, or the mortar was applied between the roof iron plate and the mortar. It is common to fill the area with caulk. However, in these cases, the water cannot be completely drained due to capillary action during rain, leading to internal corrosion and mold, and the disadvantage that the durability of the wall cannot be improved. There is.

(Problems to be solved by the invention) This invention satisfactorily solves each of the above-mentioned drawbacks, and in the eaves drainage material, drainage at the boundary between the eaves and the mortar on the outer wall surface. To provide a draining material that reliably improves the durability of a building, allows mortar coating on an external wall to be easily applied using fixed wood, and provides a beautiful finish.

(Means for Solving the Problems) In the eaves draining material of this invention, as a means to solve all the above problems, the eaves draining material is made of synthetic resin in the longitudinal direction, and the front side of the substrate 2 is made of synthetic resin. A supporting projecting piece 3 is provided in a protruding manner, leaving a hanging piece 5 below.
An inwardly directed upright piece 4 is formed on the upper surface side of this supporting protrusion piece 3. Furthermore, several reinforcing protrusions 7, 7 are formed on the back side of the substrate 2.

The above object is achieved by forming cutout holes 8, 8, . . . on the tip edge of the upright piece 4 to facilitate communication of mortar.

(Example) Next, an example of this invention will be described with reference to the drawings. A draining material 1 shown in FIG. 1 is formed into a strip shape in the longitudinal direction using a constituent material such as synthetic resin. This draining material 1 has a base plate 2 in the longitudinal direction, and a support protrusion 3 is integrally provided on the upper part of the base plate 2, leaving a hanging piece 5 of a required size below the surface side. The supporting protrusion 3 may be inclined downward as shown in FIG. 2, or protrude substantially horizontally as shown in FIG. 4.

Next, the support protrusion 3 is formed with an upright piece 4 that is substantially inclined inward from the edge 9 on the upper surface side. At the end edge of this upright piece 4, semicircular cutout holes 8, 8, etc. are formed at required intervals.

Further, the substrate 2 is provided with at least one row of through holes 6, 6, . . . formed in various shapes along its longitudinal direction.

Further, on the back side of the substrate 2, a plurality of abutment protrusions 7, 7, such as a dovetail shape, which are well bonded, are integrally formed at predetermined intervals in the longitudinal direction.

Reference numeral 10 indicates a draining piece 1 connected to a hanging piece 5;
It shows the space formed between the front surface of the eave main body 12 and the metal plate 13. Reference numeral 11 indicates mortar for finishing the wall surface, and reference numeral 15 indicates a column body such as a pillar or a stud.

(Function) This invention has the above-mentioned configuration, and now to explain this embodiment with reference to the drawings, the one shown in FIG. The eaves body 12 at its lower end is fixed and a side template is attached to a column body 15 such as a column or stud. Hammer this template thoroughly with a thick nail, etc.
Finish by adding a soffit to the soffit.

The lower end of the draining material 1 fixed to the waterproof sheet 14 is tightly attached to the upper surface of the eaves main body 12 with a gap 10 provided therebetween. Next, mortar 11 is applied to the surface of the lath to finish it. When the end edge 9 of the tip of the support protrusion 3 is used as a fixed wood and the mortar finish is applied, the notched holes 8, 8 of the upright piece 4... This allows the mortar to enter well, and the through holes 6, 6, etc. provided in the substrate 2 also allow the mortar to enter well, and the two are integrated.

(Effects of the invention) As described above, according to this invention, a gap is naturally formed between the eaves main body and the upper wall, so rainwater can be completely drained and there is no need to worry about rainwater infiltrating into the interior. Because there is no mold, it does not corrode or mold easily, and when installing mortar,
The tip plays the role of a fixed tree and has the effect of making the finish of the mortar application very beautiful.

Furthermore, since the drainage material is molded in the longitudinal direction from synthetic resin, it is easy to manufacture and suitable for mass production. By leaving a hanging piece below the surface side of the draining material and forming a supporting protrusion, the size of the space between the walls can be adjusted as appropriate by changing the length of the hanging piece, and the draining effect can be effectively set. effective. In addition, it has the excellent property that the tip of the supporting protrusion can easily serve as a standing tree during mortar construction. Furthermore, by forming an inwardly directed upright piece on the upper surface side of the support protrusion, it is possible to improve the bite between the draining material and the mortar, prevent separation of the mortar, and provide sufficient support for the mortar. be.

In addition, the board is sufficiently reinforced by several protrusions provided on the back side of the board of the draining material, and
Due to the effect of being able to stably press against a waterproof sheet, etc., and the several cutout holes provided at the edge of the upright piece, there is good communication between the mortar on the front and back of the upright piece, and the mortar is integrated. Moreover, it has the effect of strengthening the bond between the draining material and the mortar.
