Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waterproof capping device that is attached to the side joints of the outer wall of a building, and particularly relates to a long mounting member that is fixed to the outer wall and a long mounting member that is fitted onto the elongated mounting member. The present invention relates to a waterproof capping device comprising a short support member, and a cover member that is fitted to the mounting member via the support member and supported by the support member.

Such a waterproof capping device is disclosed in Japanese Patent Application Laid-Open No. 52-95825, but the watertightness between the mounting material and the outer wall and between the cover material and the upper end of the mounting material after the capping material is installed is not complete. In particular, there is a risk that rainwater flowing down the exterior wall surface may enter from between the top end of the mounting material and the cover material due to capillary phenomenon.If the mounting material is fastened with screws, the rainwater that has entered may enter the exterior wall through the screw penetration part. There is a risk that it will penetrate. In order to avoid this kind of influence and to fix the mounting material without using screws, the mounting material should be pre-attached to the tower exterior wall before the construction of the exterior wall, and then the holder member and This requires post-installation work to install the flashing member, which poses many difficulties in waterproofing work.

In this invention, by adding a member to the long mounting material and the cover material, which work together to perform a sealing action and a capillary phenomenon blocking action due to the gap, the mounting material can be easily attached with screws. It can be securely fixed to the exterior wall and can be installed later. Furthermore, the positioning of the cover material and the mounting material can be easily done by simply fitting and locking the locked edge of the cover material into the fitting part of the mounting material. It is an object of the present invention to provide a waterproof capping device which prevents rainwater from entering between the upper end of the cover material and the upper end of the cover material.

Next, embodiments of the invention will be described based on the drawings.

In the figure, 101 is a core wall that constitutes the building frame, 1
02 is the waist wall finishing material. For example, the waist wall finishing material is constructed by applying mortar 102a and pasting a waterproof layer 102b such as a waterproof sheet or asphalt roofing on the surface of the mortar 102a. However, in addition to the above materials, wall finishing materials such as tiles, siding, and panels may be used as the waist wall finishing material.

A ₁ is a mounting material that is the first component of the waterproof capacitor device according to the present invention, B ₁ is a support material that is a second component, and C ₁ is a cover material that is a third component.
The mounting member A ₁ , the support member B ₁ and the cover member C ₁ are all prefabricated in a factory from elongated sections extruded from hard synthetic resin or preferably from aluminum or other metal material.

The mounting material A ₁ is elongated, for example, on the order of several meters, and includes a fixed portion 1 fixed to the core wall with screws 4 or nails that are in contact with the outer surface of the core wall 101, and an upper side of the fixed portion. a fitting part 2 having a groove 2a formed in the part and opening downward and outward; and a locking part 3 protruding in a direction opposite to the core wall at the lower part of the fixing part 1.
It has both. The fixing part 1 is made such that even if it is fixed by pressing it against the core wall 101 with screws 4 or nails, the vicinity of the upper and lower ends of the fixing part will not be lifted from the core wall due to the unevenness of the core wall surface. A plurality of protrusions 1a are provided on the back surface of the fixed portion.

Reference numeral 5 denotes an adjustment piece installed between the fixed portion of the screw 4 and the core wall. Core wall 10
If the surface of the adjusting piece 5 is uneven, screwing the screw 4 into the recess may deform the mounting material. Therefore, as shown in FIG. Depending on the depth of the
By cutting the adjusting piece 5 at an arbitrary cutting line to give it an appropriate thickness, it is possible to firmly mount the mounting material A ₁ without deforming it.

The fitting portion 2 is formed into a substantially 7-shaped cross section, and a support material B ₁ and a cover material, which will be described later, are inserted into the groove 2a.
The upper end of _C1 can be inserted upward through the lower opening and tightly fitted. By forming the cross-section into a 7-shaped shape, when the upper ends of the support member B ₁ and the cover member C ₁ are fitted together, the upper ends are guided by the inner wall surface of the fitting part 2, and the surface is They are designed to slide and fit together easily.
The outer part of the fitting part 2 may have a simple hanging shape, but the lower end of the hanging part extends outward to the same plane as the upper outer surface of the core wall, and the tip is bent downward. By forming the L-shaped projecting edge 2c, the projecting edge 2c receives the caulking material 14 to be applied between the lower surface 101a of the outer wall, facilitating the caulking work and preventing the caulking material from being stored. I'm sure. The locking portion 3 has a locking surface 3a at its base end, and a guide surface 3b inclined outwardly from the locking surface at its distal end.

The supporting material B ₁ is made by cutting a long material into short pieces of, for example, about 10 or more cm to 20 to 30 cm, and the upper part thereof is parallel to the inner wall surface of the fitting part 2 of the mounting material A ₁ . A rising portion 6 that rises, a support portion 7 that slopes outward from the lower end of the rising portion and further hangs down, and a retaining portion that protrudes inward from the back surface of the support portion to a vertical plane that is substantially common to the rising portion 6. It has a stop part 8 integrally.

Further, the cover material C ₁ is formed to be long like the mounting material A ₁ and has a rising portion 9 corresponding to the rising portion 6 of the supporting material B ₁ at the upper end thereof from the lower end of the rising portion. A one-sided flow part 10 that slopes corresponding to the downward slope of the support part of the support material is integrated with a drooping part 11 that hangs down from the lower end of the one-sided flow part, and as a whole, the rising part 6 of the support material is It has almost the same shape from the upper end to the lower end of the support part 7. The lower end of the hanging portion 11 has a locking edge 12 bent inward.

The rising portion 9 of the cover material C ₁ has a horizontal locked edge 15 that is locked to the outer side of the fitting portion 2 in order to improve waterproofness between the rising portion 9 and the upper end of the mounting material A ₁ . A horizontal protrusion 16 is formed that contacts the inner wall surface of the fitting portion 2 .

To attach the waterproof capping device consisting of the three members A ₁ , B ₂ , and C ₁ to the outer wall of a building, first place the upper end of the mounting material A ₁ on the lower surface 101a formed on the core wall 101. and tighten screw 4 from fixed part 1.
is screwed into a screw receiver 13 embedded in the core wall 101 to fix the mounting material to the core wall. The attachment material may be fixed either before or after the waist wall finishing material 102 is installed, but the lower surface of the locking portion 3 can be used as a parting receiver for the waist wall finishing material 102.

Next, the support material B ₁ is superimposed on the back surface of the cover material C ₁ , and in this state _, the rising portions ₆ ,
9 into the groove 2a of the fitting part of the mounting material _A1 , place the tip of the locking part 8 on the guide surface 3b of the locking part 3 of the mounting material, and then connect the cover material _C1 and support. When the material B ₁ is strongly pushed toward the mounting material A ₁ , the rising portions 6 and 9 further enter the fitting portion 2 upwardly due to the guiding action of the guide surface 3 b , and the locked edge 15 moves into the fitting portion 2 . Since the locking part 8 is fixed on the outer side of the ridge 2c, that is, the lower surface of the protruding edge 2c, the locking part 8 is elastically deformed slightly upward and rides on the locking surface 3a of the locking part 3, and is locked by the restoring force of the locking part 8. It is locked to the surface 3a. If a large number of narrow grooves extending in the longitudinal direction of the attachment member are formed on the upper surface of this locking surface, the frictional locking of the locking portions 8 and 3 becomes even more reliable.

In order to increase the effectiveness of the waterproofing effect, the support member B ₁ is installed at a position that covers the threaded portion of the screw 4 of the mounting member A ₁ from the outside. Since a locking edge 15 protruding outward is provided on the outer surface of the rising portion 9 of the cover material C ₁ , the upper end of the rising portion 9 of the cover material C ₁ is attached to the mounting material via the support material B ₁ .
When fitted into the fitting part 2 of _A1 , the locked edge 15 is pressed against the outer lower surface of the fitting part 2 of the mounting material, so that a primary sealing effect is obtained at this part. Further, the locked edge 15 is provided at a position where a plurality of gaps are formed between the horizontal projecting edge 16 at the upper end of the rising portion 9 and the bottom of the fitting portion 2 when the projecting edge 2c is locked. ₁ mounting material A and ₁ covering material C.
This prevents capillary action from occurring during the process. A horizontal ridge 16 is provided at the upper end of the rising portion 9.
, the tip of the protrusion 16 comes into contact with the outer inner wall surface and the inner inner wall surface of the fitting part, exerting a secondary and tertiary sealing effect. There is no wobbling, and the locked edge 15
Gaps 17 and 18 are formed between the projecting edge 16 and between the projecting edge 16 and the bottom of the fitting portion 2, respectively, for blocking capillary action and reducing pressure.

When such a locked edge 15 and a protruding edge 16 are provided to ensure watertightness between the upper ends of the mounting material A ₁ and the cover material C ₁ , even if wind mixed with rain blows up, the above-mentioned upper sealing effect will be maintained. The air gap prevents wind mixed with rain from blowing deeply upward through the gap between the lower end of the cover material and the waist wall finishing material, resulting in good waterproofing. Further, since rainwater flowing down the outer wall surface does not reach the penetration part of the screw 4 from between the upper end of the mounting member and the cover member, water resistance is improved.

As described above, by providing the locked edge 15, the support member B ₁ and the cover member C ₁ are able to absorb the elastic restoring force of the locking portion 8 of the support member B ₁ and the positioning engagement of the locked edge 15. It is firmly held to the mounting material by the stopper. In such a holding structure, the cover material _C1 is rotated clockwise in the figure around the contact point between the locked edge 15 and the protruding edge 2c by the strong wind blowing along the waist wall surface, and is supported. In order to prevent the material B ₁ and the cover material C ₁ from coming off the mounting material A ₁ , the locking positions of the locking portions 3 and 8 are set closer to the core wall 101 than the vertical line passing through the contact point, that is, the locking portions 3 and 8 are moved away from the mounting material A 1. It is set on the opposite side.

The embodiment shown in FIG. 3 has an exterior finishing material 103 on the surface of a core wall 101 in a rising wall of a building.
The shape of the mounting material A ₂ has been improved to accommodate the case in which the mounting member A 2 is provided, and the parting receiving edge 3 ′ of the waist wall finishing material 102 is provided separately from the locking portion 3 .

That is, since the exterior finishing material 103 has some thickness, the lower surface of the exterior finishing material 103 and the mounting material
In order to save the amount of caulking material 14 applied between the mounting material A ₂ and the mounting material A ₂ , the fitting portion 2 of the mounting material A 2 is extended outward from the fixed portion 1 and brought close to the surface of the exterior finishing material 103 . In this case, a projecting edge 2b is integrally provided on the upper surface of the fitting part 2 extending in the direction of the core wall to reinforce the fitting part itself, and also to strengthen the fitting part itself.
It is preferable to also serve as a water return between 03 and 03. Furthermore, when the locking portion 3 is formed separately from the parting receiving edge 3', it is possible to provide the locking portion 3 with the same function as the locking portion 8 of the support member B ₁ in the above embodiment. . Therefore, in this example,
The support member B ₂ is provided with a locking portion 8' projecting slightly downward at the upper end of the support portion 7, and the locking portion 3 has a locking portion that engages and locks the guide surface 3b and the locking portion 8′. A locking recess 3a' is provided. The same locking effect can also be obtained by forming the locking portion 8' at the upper end of the support portion 7 in a concave shape and providing the locking portion 3 with a convex portion that is fitted into and locked in the locking portion.

In any of the above embodiments, the supporting material
B ₁ and B ₂ are shaped such that their respective outer surfaces adhere to the back surfaces of the cover materials C ₁ and C ₂ when the cover materials have been attached. In this case, there is an advantage that the support material can also be used as a joint material for adjacent cover materials in each embodiment.

As described above, in the waterproof capping device according to the present invention, when the rising portion of the cover material and the rising portion of the support material are pushed into the fitting portion of the mounting material, the locked edge of the cover material is engaged with the fitting portion of the fitting portion. The cover material is supported by positioning and locking on the outside part, and due to elastic deformation of either the locking part of the support material or the mounting material, the locking part of the support material rides up to the locking part of the mounting material and is locked. Since it is fixed to the mounting material through the material, the cover material can be mounted reliably and easily, and the abutment between the locked edge and the lower surface of the outside of the fitting portion prevents wind and rain from blowing into the inside of the cover material. This prevents this and provides a high sealing effect between the mounting material and the upper end of the cover material. In addition, when the cover material is attached, a void is formed between the upper end of the rising part of the cover material and the inner wall surface of the fitting part of the mounting material, so wind and rain etc. blow in due to capillary action and depressurization action are blocked. High watertightness can be achieved between the long cover material and the upper end of the mounting material.
