Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a building starter used for a building, around a base of a structure, around a window, and other appropriate openings.

(Prior Art) Conventionally, as a starter for this kind of construction, Japanese Patent Laid-Open No. 61-98
There is one as shown in Japanese Patent No. 858. This architectural starter 1 is shown in FIGS. 3 (A), (B), (C),
As shown in (D), (E), and (F), in each of these examples, the vertical nailing portion 1a, the bottom face portion 1b connected to the lower end thereof, and the outside of this bottom face portion. Outer wall material 2
It is formed by connecting a protrusion 1c that engages with the reverse groove 2a formed at the lower end of the.

(Problems to be solved by the invention) However, in any of the conventional construction starters shown in FIG. 3, the projection 1c formed on the construction starter 1 is formed at the lower end of the outer wall material 2. When the outer wall member 2 is attached to the building starter 1 by engaging the reverse recessed groove 2a, the back surface 2b on the lower end side of the outer wall member 2 has the vertical nailing portion.
The rainwater that comes into contact with the surface 1a and hits the surface of the outer wall material 2 comes into contact with the reverse concave groove 2a at the lower end of the outer wall material 2 and the projection 1c of the building starter 1 and the outer wall material due to the capillary phenomenon. There is a problem that it penetrates into the contact between the lower end of 2 and the rear surface of the lower end, the bottom surface 1b of the building starter 1 and the vertical nailing portion 1a, and easily penetrates into the inner surface side of the outer wall material 2. However, there was a problem in that the rigidity was low and it was weak against wind pressure.

The present invention solves the above-mentioned problems, and can reliably block the infiltration (surrounding) of rainwater to the inner surface of the outer wall material due to the capillary phenomenon (rim cutting), and further increase the rigidity in terms of shape and wind pressure. It is an object of the present invention to provide a construction starter that is strong against the above-mentioned problems and that can further improve the mounting positioning of the lower end of the outer wall material and the mounting stability.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a convex portion formed by bending so as to be fit to the inner surface of a reverse concave groove formed in the lower end of the outer wall member in the longitudinal direction, A step portion that extends substantially horizontally inward from the lower end of the convex portion and is in contact with an inner edge of a reverse concave groove formed at the lower end of the outer wall member, and an inner horizontal portion that extends substantially horizontally inward from the lower end of the step portion. The vertical nailing portion extending substantially vertically upward from the end of the inner horizontal portion is integrally bent and formed.

(Example) Hereinafter, it demonstrates concretely based on the Example shown in figure. FIG. 1 is a perspective view of the architectural starter 3 (hereinafter referred to as the starter body 3), and FIG. 2 is a diagram showing the starter body 3 around the base of a building, around windows, and other appropriate openings, etc. The outer wall member 4 is attached to the starter main body 3 by means of the
Is a convex portion 3a with which a reverse concave groove 4a formed in the longitudinal direction at the lower end of the outer wall member 4 engages, and a reverse concave groove 4a formed at the lower end of the outer wall member 4 that extends substantially horizontally from the lower end to the convex portion 3a. Step 3b with which the inner edge 4b of the step abuts, an inner horizontal portion 3c extending substantially horizontally inward from the lower end of the step 3b, and a vertical nail extending substantially vertically upward from the end of the inner horizontal portion 3c. The hitting portion 3d and the hitting portion 3d are integrally formed by bending, for example.

Further, the manufacturing means of the starter body 3 is not limited to the bending forming means of the metal plate material, and various means can be used. For example, a molding means such as an aluminum sash or a plastic molding means can be used.

In the drawing, 3e is a corrugated rib formed on the outer hanging portion of the convex portion 3a, which increases the rigidity of the convex portion 3a and prevents rainwater from entering upward due to a capillary phenomenon. This corrugated rib bites into the reverse recessed groove 4a formed at the lower end of the outer wall member 4 by the elastic effect, and has the effect of further improving the stability of its mounting.

The outer wall member 4 is made of a conventionally known metal siding bond or any other suitable exterior material. 4c is a metal plate, 4d is a back surface material, and 4e is a synthetic resin foam. Further, 5 is a frame member such as a base or window of a building, an opening, 6 is a pillar, a stud, a furrow, or another wall base, 7 is a draining plate, such as a thin metal plate, an aluminum plate, a plastic plate, etc. , Are formed of appropriate materials.

As shown in FIG. 2, the starter body 3 thus formed is fixed to the wall base 6 by nailing it.

Then, when the convex portion 3a of the starter body 3 is engaged with the reverse concave groove 4a formed at the lower end of the outer wall member 4, the inner edge 4b of the reverse concave groove 4a comes into contact with the step portion 3b, and the outer wall member 4 4 is attached to the starter body 3.

Then, it is surrounded by the inner side surface of the lower end portion of the outer wall member 4, the inner horizontal portion c of the starter body 3 and the nailing portion 3d,
A space portion 9 is formed, and this space portion 9 has a heat insulating effect and a dew condensation effect, and even if rainwater enters the inner surface of the outer wall member 4, this rainwater is collected in the space portion 9, Further penetration of the building inside is prevented.

Further, the present invention can be used for new construction and renovation.

(Effects) According to the present invention, the convex portion bent to fit the inner surface of the reverse concave groove formed in the lower end of the outer wall member in the longitudinal direction, and extending substantially horizontally inward from the lower end of the convex portion. A step portion with which the inner edge of the reverse groove formed at the lower end of the outer wall member abuts, an inner horizontal portion that extends substantially horizontally inward from the lower end of the step portion, and a substantially vertical upward direction from the end of the inner horizontal portion. Since the extending vertical nailing portion is characterized by being integrally bent, the inner side surface of the lower end portion of the outer wall material, the convex portion of the starter body, and the lower end portion of the outer wall material are formed. Rainwater that hits the outer wall material due to the step portion where the inner edge of the formed reverse concave groove abuts, the inner horizontal portion, and the space portion surrounded by the vertical nailing portion easily inside the building due to the capillary phenomenon. It is possible to reliably prevent intrusion, and by the convex portion and the stepped portion,
It has various practical effects, such as greater rigidity in shape, resistance to wind pressure, etc., and further higher positioning and mounting of the lower end of the outer wall material, and more stable mounting. is there.
