A portion extends in front of the outer surface of the frame a to form a space 14 on the lower side.

On the other hand, above the water receiving part 12, a substantially triangular draining cavity 15 is formed which is surrounded by the water receiving part 12, the hanging part 11, and the waterproof layer b in the construction state. Therefore, drain holes 16 for communicating the drain cavity 15 with the space 14 are opened at appropriate intervals at the lower end of the hanging portion 11.

The receiving portion 5 provided at the lower edge of the opposing surface portion 9 is
A relatively narrow locking piece 6 extends downward from the front edge of the receiving part 5 and extends in a brim shape so that the front edge is located slightly lower than the rear edge. It consists of a contact piece 17 extending from the edge so as to be able to come into contact with the outer surface of the frame a. This contact piece 1
Numeral 7 is for making the main body 2 sit better when tightening the screw 18, as will be described later, and although it extends downward in the illustrated embodiment, it may also extend upward. and,
Among the receiving portions 5, an outer receiving portion 5a extending outward from the opposing surface portion 9 supports the lower edge of the waterproof layer b. Incidentally, it is preferable that the width of the outer receiving part 5a is set larger than the thickness of the waterproof layer b, so that the front edge extends to the outside of the waterproof layer b. With this configuration, even in the case of the highly fluid waterproof layer b, there is no risk of staining the outer wall of the frame a. On the other hand, in the inner receiving part 5b extending inward from the facing surface part 9, a communication hole 19 is provided that allows the space 14 surrounded by the frame a and the main body 2 to communicate with the outside air.
will be established at an appropriate location. Therefore, moisture such as water vapor and condensed water generated from the frame a can be collected at the inner receiving portion 5b and discharged to the outside through the communication hole 19.

Further, the above-mentioned presser metal fittings 3 may be long members extending along the lateral direction of the body a, or may be short members arranged at appropriate intervals in the lateral direction of the body a.
A clamping part 2 with a surface area sufficient to hold down the end of the waterproof layer b
It has 0. In the illustrated embodiment, a hook-shaped engagement part 21 is formed on the upper edge of the clamping part 20 and projects forward and is open at the bottom. A reinforcing rib 22 is provided protruding from the lower edge.

Furthermore, the above-mentioned cover member 4 is a long member capable of laterally covering the corner of the frame a,
a flat plate portion 23 that can come into contact with the upper surface of the waterproof layer b;
Swash plate portion 24 extending diagonally upward and forward from this flat plate portion 23
The swash plate portion 24 includes a top portion 25 extending substantially horizontally from the upper edge of the swash plate portion 24, and a vertical plate portion 26 hanging down from the front edge of the top portion 25. Incidentally, it is preferable to provide a non-slip member 27 on the lower surface side of the flat plate portion 23. As shown in the drawing, for example, on the surface of the vertical plate portion 26 facing the main body a, an engagement member provided on the presser metal fitting 3 is provided at a height position below the extension line of the upper surface of the main body a. An engaging piece 28 extending upward is provided so as to be engageable with the portion 21. Also,
A locking portion 7 having a locking groove 7a that opens upward so that the locking piece 6 of the receiving portion 5 described above can be inserted is provided on the lower edge of the vertical plate portion 26. A lower edge piece 29 is provided that extends obliquely downward toward a. As will be described later, this lower edge piece 29 functions as a handle or finger hook during operation, or as a drainer. In the illustrated embodiment, the engagement piece 28 located above is connected to the engagement piece 7 of the engagement portion 7 located below.
It is placed slightly closer to body a than b. The cover member 4 having the above-mentioned structure is formed by integrally molding a metal material such as aluminum or stainless steel or a synthetic resin material having appropriate elasticity.

The elastically deformable portions of the cover member 4 described above are the swash plate portion 24, the top portion 25, and the upper half portion of the vertical plate portion 26. At this time, a relatively large amount of deformation is applied to the swash plate portion 24, a medium amount of deformation is applied to the top portion 25, and the upper half portion of the vertical plate portion 26, that is, the portion above the engagement piece 28 is It is desirable to set the amount of deformation relatively small.

Next, a construction method using the waterproof layer b end treatment device 1 configured as described above and the functions of each part will be explained.

The framework a of the building on which the waterproof layer b is provided is mainly non-walking parts such as roofs, rooftops, eaves, and the tops of parapets, and the materials of the framework a include reinforced concrete (RC), lightweight foam, etc. Concrete (ALC), precast concrete (PC), etc. can be used.

In the waterproof layer b end treatment device 1 of the present invention, first, the mounting plate portion 8 of the main body 2 is placed on the upper surface of the skeleton a, and
The contact piece 17 of the receiving part 5 is brought into contact with the outer surface of the building body a, and in this state, the building body a is inserted through the mounting hole formed in the mounting plate part 8.
Anchor bolts 13 serving as fixing means are tightened toward , and the anchor bolts 13 are used to fix the structure to the frame a. At this time, the main body 2 and the main body a are placed on the underside of the main body 2.
A space 14 is formed surrounded by. Furthermore, this space 14
Since the lower side of the space 14 is almost covered by the inner receiving part 5b, there is no risk of rainwater entering the space 14 even if it is rolled up.
There is no need to fill a sealing material between the inclined surface portion 10 and the frame a. Further, water vapor or condensed water generated from the frame a, or moisture rising due to capillary action, can be collected on the upper surface of the inner receiving portion 5b and discharged from the communication hole 19.

After the main body 2 is attached to the frame a as described above, the waterproof layer b is laid down. This waterproof layer b is, for example, an asphalt waterproof material, a sheet waterproof material such as rubber or vinyl chloride, or the like. In addition, in the illustrated example, the asphalt material is
The case where it is made into layers is shown.

The above-mentioned waterproof layer b is laid on the upper surface of the frame a, the end part is aligned with the above-mentioned main body 2, the lower edge is supported by the outer receiving part 5a of the main body 2, and the presser metal fitting 3 is exposed near the lower end. ,
As a fixing means, for example, a screw 18 passed through the presser metal fitting 3 is screwed into the opposing surface portion 9 of the main body 2 and fixed. Screw 18 above
is set to a length such that the tip remains within the space 14 when screwing is completed. Therefore, condensed water transmitted through the screw 18 or rainwater that may have entered the space 14 can be allowed to fall into the space 14 and discharged to the outside through the communication hole 19. Furthermore, when fastening the screws 18, the opposing surface portion 9 is supported by the inner receiving portion 5b of the receiving portion 5 and the contact piece 17 and the distance from the frame a does not change, so the opposing surface portion 9 may wobble. Moreover, since the tip of the screw 18 protrudes into the space 14 and does not reach the frame a, the tightening work becomes easy. By fixing the ends of the waterproof layer b in this way, the waterproof layer b will not shift up or protrude. In addition, in this state, there is already a sufficient rain-shedding effect, and the function as a waterproof layer can be satisfied.

After fixing the presser metal fitting 3 and securing the end of the waterproof layer b, the cover member 4 is attached. To attach this cover member 4, place the flat plate part 23 of the cover member 4 on the upper surface of the waterproof layer b, and hold the lower edge piece 29 or hold the top part 2.
5, press down against the elasticity of the cover member 4 itself, and push it slightly toward the body, and press the presser metal fitting 3.
After dodging the engaging part 21 and the locking piece 6 of the receiving part 5, release your hand. Then, the flat plate part 23 of the cover member 4 comes into contact with the waterproof layer b due to its own elasticity, the engaging piece 28 engages with the engaging part 21 of the presser metal fitting 3 from below, and the locking groove 7a is brought into contact with the receiving part. It engages from the lower side of the locking piece 6 of No. 5 to cover the upper corner of the frame a. In addition, in the figure, the engaging piece 28 and the locking groove 7a
The reason for assuming a form in which the parts are engaged from below is not only for the sake of workability, but also because the part of the building where this device is installed is a place where the wind pressure is extremely large. Moreover, the wind pressure is greater on the windward side, so that the airflow is blown up. In other words, this is done in consideration of the fact that the force that tends to lift the cover member 4 upwardly due to the air current acts predominantly on it.

In the cover member 4 attached as described above, since the engaging piece 28 engages with the engaging portion 21 of the presser metal fitting 3, deformation of the vertical plate portion 26 is suppressed as much as possible and the alignment is maintained. This makes it possible to improve the so-called fit of the cover member 4, especially at the upper end thereof, and to ensure the adhesion of the cover member 4 to prevent it from falling off over time. Furthermore, since the flat plate part 23 of the cover member 4 presses down the upper surface of the waterproof layer b, the waterproof layer b does not swell up over time.

[0022] At an appropriate stage, finishing material c for the outer wall, such as tiles or stones, is attached to necessary locations such as the outer surface of the frame a.

When rainwater sprays onto a building in which the waterproof layer end treatment device 1 as described above is installed, the waterproof layer b not only stops the water from reaching the frame a, but also prevents it from blowing up and flowing around due to capillary phenomenon. It can be prevented. That is, since the lower edge piece 29 provided at the lower edge of the cover member 4 functions as a draining piece, it is possible to suppress rainwater from rolling up. Further, a space 14 is provided below the waterproof layer b, and this space 1
4 is blocked by the receiving part 5, so that splashes of rainwater are prevented from blowing into the space 14. Even if droplets blow into the space 14 or rainwater rises between the main body 2 and the waterproof layer b due to capillary action, the space 14
has a sufficient height so that it does not reach the top surface of the frame a, and since capillary action is blocked by the drainage cavity 15, further rise of rainwater can be prevented. Moreover, the rising rainwater is collected in the water receiving part 12 and discharged from the drain hole 16 to the space 14, and from the space 14 is collected by the communication hole 19.
It is discharged to the outside through. Therefore, stains and mold will not occur on the frame a due to minute water leaks or water vapor.

[0024] In order to apply the waterproof layer end treatment device 1 having the above-described structure to the corner portion of the frame a, it goes without saying that the cover members 4, which are the members disposed along each side, are required.
The main body 2 may also be cut so that they can be butted against each other, and there is no need to provide a separate member for water-stopping, such as a back plate for a joint, on the back side.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and can be carried out as appropriate without changing the configurations set forth in the claims.

[0026]

[Effects of the Invention] According to the present invention, not only is it easy to manufacture each member, but there is no need for bending at the construction site, so there is no need for special tools or skilled techniques, and even an amateur It can be easily constructed. Furthermore, after construction, the ends of the waterproof layer can be securely fastened, and the waterproof layer will not protrude or swell over time. Furthermore, since sprayed rainwater does not enter directly or through capillary action, there are no problems caused by rainwater intrusion, such as stains or mold formation. Furthermore, the straight or planar portions after completion are properly aligned, so-called good alignment, and this state can be maintained for a long period of time. Furthermore, inspection work associated with maintenance after a long period of time requires removing and driving screws because the cover member is engaged by springback and there is no waterproof material on the back plate for the joint. is not required and can be easily removed and restored. Therefore, according to the present invention, it is possible to provide a waterproof layer end treatment device with extremely high practical value.
