Abstract

PROBLEM TO BE SOLVED: To provide a water drip which also functions as a starter portion which enhances the waterproofness and venting performance of a wall surface. SOLUTION: The water drop 1 is comprised of a starter portion which is obtained by vertically extending fixed portion 2 of the water drop 1 in parallel with a wall member 11, bending a projective end from a midpoint of the vertically extending fixed portion 2 to form an engaging portion which engages with the wall member 11, and a water drop portion 5 protruding from a lower edge of the fixed portion 2 at a blunt angle to form a gradient. An end which bifurcates from a point near the lower edge of the fixed portion 2 and almost vertically extends therefrom, is bent at a blunt angle, to thereby form a slope portion 4. Further, a plurality of venting holes are formed in the slope portion 4 with a predetermined pitch in a manner penetrating therethrough so that air flows therethrough. Each venting hole is formed like a slit so as to prevent invasion of noxious insects. Further, when the venting hole is formed by pressworking or the like, the presswork can be performed without interference of a surface vertical portion 5b of the water drop portion 5, and the workability is rendered efficient, to thereby reduce costs. Further, the life of a press die can be drastically extended.

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is an exterior member for buildings and structures, and is used as a draining material for a starter of a horizontal wall material. It is related with the draining material which improves the air permeability between the wall material. [0002] Various wall materials and members for wall materials have been proposed as materials for covering the walls of buildings and structures. For example, as this kind of starter draining material, there are Japanese Utility Model Laid-Open No. 61-91943, Japanese Patent Laid-Open No. 8-4130, and the like. [0003] However, in this example, the starter and draining part are each a combination of two separate members, and there are disadvantages in workability. On the other hand, the structure is complicated and expensive. There is a problem in that the air permeability of the wall surface is not considered at all. The present invention is made to solve the above problems,
The purpose of the present invention is to produce a draining product that also has a starter portion for a horizontal wall material and can improve the waterproofness of the wall surface and the air permeability between the wall surface and the wall material by an inexpensive method. Means for Solving the Problem A drainer 1 disposed in a longitudinal direction near the lower end of a wall surface and used for starting to apply a wall material 11 is parallel to the wall surface 20 and a nail fixing portion 2 ( (Hereinafter referred to as a “fixed portion”) is provided in the vertical direction, and the starter portion 3 formed by bending the tip protruding from the middle thereof to form the engaging portion 3a with the fitting portion 15 of the wall material 11; It has a draining portion 5 consisting of a protruding portion 5a having a lower end protruding at an obtuse angle to form a gradient and a surface vertical portion 5b formed by further bending the tip thereof, and branches from the vicinity of the lower end of the fixing portion 2 to be substantially vertical. The tip extending in the direction is bent at an obtuse angle to form an inclined portion 4 whose lower surface is directed downward from the surface vertical portion 5b, and a plurality of air is circulated through the inclined portion 4. Ventilation hole 6 is provided, and the shape thereof is slit-like ventilation hole 6.
It is formed in a. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a drainer with a starter according to the present invention will be described below. 1 and 2 are explanatory views showing an example of the above-described structure, which is formed as follows. That is, the fixing portion 2 disposed in the longitudinal direction in the vicinity of the lower end of the wall surface 20, the tip protruding from the middle of the fixing portion 2 is bent, the rising engagement portion 3 a is provided, and the wall member 11 is fitted to the female Starter part 3 formed to engage with part 15
A protruding portion 5a provided with the lower end of the fixed portion 2 projecting at an obtuse angle, a draining portion 5 formed by a surface vertical portion 5b obtained by bending the extending portion 5a in the vertical direction, and the protruding portion 5a A slit-like vent hole that is branched in the middle and extended in a substantially vertical direction, bent at an obtuse angle to form an inclined portion 4, and has a plurality of penetrating holes in the longitudinal direction of the drainer 1 so that air can flow. The inclined portion 4 provided with 6a and the support portion 4b formed by bending the tip of the inclined portion 4 extending toward the wall surface are integrally formed by, for example, extruding and pressing the metal material. Is. The tip of the engaging portion 3 a of the draining body 1 is
The female fitting portion 15 of the wall material 11 that is in contact with the engaging portion 3a.
It is formed in a substantially cylindrical shape so as not to damage the inner surface. Further, the support portion 4b that extends the inclined portion 4 of the draining body 1 is formed so as to have a gradient in which the wall surface 20 side is upstream and the inclined portion side is downstream, and the inclined portion 4 is provided with the inclined portion. A plurality of slit-like vent holes 6a extending in parallel from the side 4 to the bent part extending to the support part 4b toward the support part side are opened in parallel, and projecting downward so as to be substantially in contact with the slit-like vent hole 6a. The bottom leakage prevention piece 4c was disposed. As described above, according to the present invention, the drainer 1 disposed in the longitudinal direction in the vicinity of the lower end of the wall surface and used when starting to apply the wall material 11 is parallel to the wall surface 20. The fixing portion 2 is arranged in the vertical direction, the tip protruding from the extending portion of the fixing portion 2 is bent and the engaging portion 3a is provided upward, and the tip thereof is formed in a substantially cylindrical shape, Consideration is made so as not to damage the inner surface of the female fitting portion 15 of the wall member 11 that is in contact with the engaging portion 3a, and the rising engaging portion and its tip serve as the starter 3, A protruding portion 5a protruding at an obtuse angle at the lower end of the fixed portion 2, a surface vertical portion 5b obtained by bending the extending portion 5a in the vertical direction, and a point extending from the surface vertical portion 5b bent inward. Reinforcing part 5
c and a bottom leakage prevention piece 5d at the front end of the surface vertical part 5b, and the draining part 5 is formed, so that the draining part 5 can be combined with the starter part 3 as compared with the prior art. The overall shape is simple, the amount of materials used is very small, and the drainer 1 can be constructed at a low cost. The lower end of the fixed portion 2 is branched from the extending portion of the overhanging portion 5a protruding at an obtuse angle and extended in a substantially vertical direction, and the tip thereof is bent at an obtuse angle to form an inclined portion 4. The inclined portion 4 Since a plurality of slit-like vent holes 6a are provided so that air can flow therethrough, the warm outside air at the bottom of the drainer 1 passes through the slit-like vent holes 6a by the draft and the wall surface Since it raises and distribute | circulates between the pitches of each trunk edge 19 arrange | positioned between 20 and the wall material 11, there exists an effect which can fulfill | perform the function of ventilation which is the initial objective. Further, since the support portion 4b provided at the tip of the inclined portion 4 is formed to have a gradient (that is, a downward gradient from the wall surface) in which the wall surface is upstream and the inclined portion is downstream. Even if rainwater that has entered the interior of the drainer 1 or between the pitches of the trunk edges 19 or water that has condensed on the wall surface 20 hangs down, the rainwater or water will be deposited on the inner surface of the support portion 4 b of the drainer 1. Along the downstream side, and through the slit-like air holes 6a provided from the inclined portion 4 to the bent portion extending to the support portion 4b, the effect of being discharged without leaking from the support bottom leakage prevention piece 4c. There is. Furthermore, when the slit-shaped air holes 6a arranged at a predetermined pitch in the inclined portion 4 are actually formed by pressing or roll forming, the inclined portion 4 is not provided, and the inner vertical portion 4a is extended. When the surface vertical part 5b is parallel, the press working or roll molding die is formed to be obstructed by the surface vertical part 5b and to escape from the surface vertical part 5b. However, according to the present invention, as described above, the lower surface is directed downward from the surface vertical portion after extending the inner vertical portion 4a as described above. By arranging the inclined portion 4 thus formed, the inclined portion 4 is not parallel to the surface vertical portion 5b. Therefore, the mold can be formed avoiding the surface vertical portion 5b. There is an effect that can be constructed inexpensively as a whole drainer . Further, since the vent hole 6a as described above is formed in a slit shape, the width of the penetrating hole can be narrowed even if the total area of the vent holes is the same, so that cockroaches, bees and the like can be formed from the vent hole 6a. Insects enter the wall 20 and the wall 11
There is an effect that you do not have to worry about harm such as building a nest between and breeding.
