Description

  The present invention relates to an eaves arabesque that can prevent breakage of an end portion of a heat-insulating backup material disposed on the back surface of the exterior material before the installation of the side-facing exterior material, and an eaves structure using the eaves.

  Conventionally, a horizontal roof has formed an exterior surface by polymerizing (engaging) a water-side molded portion and a water-side molded portion on the lower side of the upper-side side exterior material. A heat insulating backup material made of foamed styrene is provided on the back side of the exterior material, and these heat insulating backup materials are connected to each other to form a heat insulating layer. That is, the heat insulating backup material has a protruding upper portion where the surface layer portion (upper half) extends below the water, and a protruding lower portion where the back layer portion (lower half) extends above the water. By polymerizing the upper part to the protruding lower part, a heat insulating layer without a gap can be formed.

Furthermore, the applicant of the present invention, as a prior invention, by using a heat insulating backup material having the above-described non-permeable structure, double waterproofing is achieved between the heat insulating backup layer and the exterior surface, and the heat insulating backup material and the exterior It has been found that it is highly integrated with the material and can be laid without using a hanger or the like (Japanese Patent Application No. 2017-57990).
Note that the eaves are provided with members such as eaves arabesque and eaves-holding materials that prevent rainwater that has reached the eaves from flowing from the eaves to the back side by capillary action.

For example, as a heat insulating material, Patent Document 1 describes a case where a roof is constructed with a roof material and a heat insulating material separately formed, and the end portion of the heat insulating material is processed into a shape that can be polymerized and laid in a polymerized state. Proposals have been made to obtain heat insulation performance and waterproofness. On the other hand, it is inevitable that the end portion (processed portion) of the heat insulating material is thin, and it is necessary to perform construction while paying sufficient attention to cracking and breakage. Furthermore, it has also been proposed that a heat insulating (backup) material is molded from foamed polystyrene or the like to form a water-impermeable waterproof layer.
In addition, as an eaves to be arranged at the eaves tip, Patent Document 2 discloses that eaves eaves 1 is hung and held on a lifting tool 7 fixed to a nose cover plate 10 and the upper end of a draining plate 2 corresponding to a cover material is used as a base of a roof. A fixed structure has been proposed.

JP2013-119799A JP 2005-023537 A

  However, even in the above-mentioned conventional side roof and the side roof of the prior invention, the insulation backup material is damaged during the construction in the state where the installation of the insulation backup material is finished and the installation of the side covering material is not completed. I had to do it. In particular, on the lowermost side (eave edge), a space is formed on the back side of the protruding upper portion extending to the lower side of the thermal insulation backup material at the lowermost stage, so that the pressure from above (for example, work) It was easy to cause a breakage accident when a person's shoetip) acted.

Moreover, in the roof structure like the said patent document 1, if there exists a crack or damage to a heat insulating material after laying | laying on a roof base | substrate, there exists a possibility that water leakage and heat insulation performance may fall or construction of an exterior material may become difficult. Furthermore, there is a possibility that fragments and the like will block the path as a waterproof layer and lead to water leakage.
Furthermore, in the said patent document 2, since it is a structure which fixes the upper end of the draining board 2 equivalent to a cover material to the back surface side of a roofing material, it is necessary to attach the draining board 2 before laying a roofing material. Was also a limitation.

  Therefore, the present invention provides an eaves arabesque that can prevent breakage of the end portion of the heat insulating backup material disposed on the back surface of the exterior material before the installation of the side facing exterior material, and an eaves structure using the eaves. The purpose is to propose.

The present invention has been proposed in view of the above, and is an eaves arabesque disposed at the eaves of a building, and is attached to an eaves tip of an exterior base (field material), and the eaves from the eaves The support part which supports the eaves end extended to the eave side of the heat insulation backup material arrange | positioned to the side and the eaves side shaping | molding part of an exterior material which extends to the side, and the back surface side of an exterior material is supported. It is related to the eaves arabesque characterized by having a part.
The eaves end extending to the eaves side of the heat insulating backup material has a configuration in which the eaves end extends to the eaves side, that is, a protruding upper part where the surface layer portion (upper half) extends is formed under the water. It is nothing but the configuration.

  Further, in the eaves arabesque of the present invention, the support portion includes a first horizontal piece extending to the exterior material side, and a second horizontal piece extending to the eaves side and having an engaged portion formed at the tip. We also propose an eaves arabesque characterized by

  Further, the present invention provides the eaves arabesque, wherein the eaves arabesque is provided with a fixed portion that protrudes further toward the eaves side than the engaged portion and fixes a cover material that covers the upper surface of the eaves ridge. I also propose.

  Furthermore, the present invention also proposes an eaves edge structure characterized in that the eaves arabesque is attached to an exterior base and the eaves arabesque supports the eaves edges of the heat insulating backup material.

  The eaves arabesque of the present invention can protect the eaves of a building and prevent breakage of the end portion of the heat insulating backup material during construction, for example.

  Further, when the support portion includes a first horizontal piece extending to the exterior material side and a second horizontal piece extending to the eaves side (an engaged portion is formed at the tip), You may make it adapt to the aspect which the eaves end of a heat insulation backup material protrudes in a substantially rectangular shape by making 1 horizontal piece and 2nd horizontal piece continue, or combining a 1st horizontal piece and a 2nd horizontal piece in a step shape. You may adapt to the aspect which the eaves edge of a heat insulation backup material protrudes in two steps (it protrudes in two steps).

  In addition, when it has a fixed part that protrudes further toward the eaves side than the engaged part and fixes the cover material that covers the upper surface of the eaves ridge, it is bent further inward at the eaves tip of the cover material. By providing a substantially U-shaped engagement portion and engaging the eaves tip of the eaves on the back side thereof, the cover material also serves as an arm for holding the eaves end of the eaves.

  Furthermore, since the eaves structure of the present invention attaches the eaves arabesque to the exterior base, and supports the eaves edges of the heat insulation backup material on the eaves arabesque, as described above, prevents damage to the ends of the heat insulation backup material. It can be done.

(A) The side view which expands and shows the exterior material (horizontal exterior material) used for the eaves structure of 1st Example, (b) The state which laid exterior material in a part of heat insulation backup material connected in the flow direction (C) It is side sectional drawing which shows the state which laid the exterior material in a part of heat insulation layer formed on the exterior foundation | substrate (field material), and attached the eaves edge arabesque to the eaves end.

  The eaves arabesque of the present invention is a member disposed on the eaves of a building, and is attached to an eaves tip of an exterior base such as a field material, and an exterior extending from the attachment fixed part to the eaves side An engagement portion that engages the eaves-side molded portion of the material, and a support portion that supports the eaves end that extends to the eave side of the heat insulating backup material disposed on the back surface side of the exterior material from the back surface side. Features.

  Prior to the description of each part of the eaves arabesque, the eaves end extending to the eave side of the heat insulating backup material will be described. A surface layer portion (upper half) extends under the water as shown in the illustrated embodiment described later. This is nothing but a configuration in which a protruding upper portion is formed.

The attachment fixing portion is a portion attached to the eaves tip of an exterior base such as a field material, and may have any shape as long as it can be attached to the exterior base to be attached.
For example, in the illustrated embodiment which will be described later, the eaves end of a field material having a substantially rectangular cross section is formed in a substantially U-shape that can be fitted from the eaves side, but is not particularly limited thereto. In addition, it may be fixed firmly by driving in a fixing tool such as a screw from above, and when it is formed in a substantially U shape, it can be attached to the eaves edge of the exterior basement, improving workability In addition, the mounting strength is improved.

The engaged portion is a portion that extends from the attachment fixing portion to the eaves side and engages the eaves-side molded portion of the exterior material, and can be engaged with the eaves-side molded portion of the exterior material. Such a shape may be used.
Further, the exterior material to be engaged with the engaged portion may be, for example, a side-facing exterior material or a longitudinal-side exterior material. In the former case, the exterior material may be engaged with the eave-side molded portion of the outermost lateral exterior material. In the latter case, the outermost edge of the longitudinally-wrapped exterior material may be folded back to the back side to be engaged.

  The case where the eaves-end molded portion with which the engaged portion is engaged is a side-facing exterior material will be further described.In the connection portion between exterior materials adjacent in the flow direction, the eave-side molded portion of the exterior material on the water side On the other hand, the ridge-side molded part on the underwater side is engaged with the eave-side molded part of the outermost-side exterior material arranged on the most underwater side. The engaging part becomes the engaging partner. For example, in the illustrated embodiment described later, the tip of the horizontal piece (second horizontal piece) facing the eaves is used, but the present invention is not particularly limited thereto.

The support portion supports the eave end extending to the eave side of the heat insulating backup material from the back surface side, and may have any shape as long as it can contact the eave end shape of the heat insulating backup material from the back surface.
For example, if the eaves end of the heat insulating backup material protrudes in a substantially rectangular shape, the support portion for supporting it from the back side may be a substantially horizontal lateral support piece, as shown in the illustrated embodiment described later. If the eaves edge of the heat insulating backup material protrudes in two steps (projects in two steps), the support portion for supporting it from the back surface may be a stepped L-shaped support piece.

  For example, in the illustrated embodiment to be described later, the support portion includes a first horizontal piece extending to the exterior material side, and a second horizontal piece extending to the eaves side and having an engaged portion formed at the tip. Since the first horizontal piece and the second horizontal piece are formed (arranged) on the same straight line, the above-mentioned substantially horizontal horizontal support piece can be obtained, and the first horizontal piece and the second horizontal piece are If it is formed (arranged) in a stepped shape, the above-mentioned stepped L-shaped support piece can be obtained, but it is not particularly limited to this.

  The eaves to which the eaves arabesque of the present invention is attached is an eaves tip of an exterior base such as a field material, and the exterior base is laid with an exterior material in which a heat insulation backup material is disposed on the back side, and the heat insulation backup As long as the edge of the eaves extends to the eaves side, the specific configuration is not particularly limited.

  As long as the heat insulating backup material has a configuration in which the eave end extends to the eaves side as described above, the specific configuration is not particularly limited, but in the illustrated embodiment described later. Thus, it is desirable to provide a configuration in which the ridge end extends to the ridge side so that the heat-insulating backup materials adjacent in the flow direction can be connected in a labyrinth form. That is, the heat insulating backup material has a protruding upper portion (upper overlapping portion) in which the surface layer portion (upper half) extends at the lower end of the water, and a back layer portion (lower half) at the upper end of the water. This is because, in the case of providing a configuration in which an extended protruding lower portion (lower overlapping portion) is formed, the protruding upper portion can be superposed on the protruding lower portion, and a heat insulating layer having no gap in the flow direction can be formed.

  Further, the heat insulating backup material is preferably non-permeable, specifically a foamed heat insulating backup material, particularly a material having some elasticity, for example, a single layer of synthetic resin such as expanded polystyrene, expanded polyethylene, etc. Or it is preferable to use a laminated body. This water-impermeable, foam-based, heat-insulating backup material is a material in which the bubble portions are present independently and randomly, so that the water-impermeable property is always ensured even when processing such as cutting is performed. desirable. This is because the above-mentioned “heat-insulating layer without gaps” can be used as “a waterproof layer without gaps”.

Furthermore, the surface of the heat insulating backup material may be flat or may be formed with grooves. The groove is a drainage groove for discharging dew condensation water before laying the exterior material or after laying on the heat insulating backup material without being retained on the heat insulating backup material, and is not limited to the flow direction, in particular The phased-up portion (side edge) may be "inclined" facing inward (to prevent water from reaching the side edge).
Also, the back surface of the heat insulating backup material may be flat, or a space (gap) may be provided by forming a protrusion, a groove, or the like. The formed space (gap) enables air to flow between the base material and the like.

  The exterior material is a horizontal exterior material that is laid on the heat insulating layer and has an eaves-side molded portion at the lower end thereof, and specifically limits the specific configuration including the eave-side molded portion. It is not a thing, but roll molding of well-known metal materials, such as a surface decorative steel plate of about 0.4 to 1.6 mm, a laminated steel plate, a plated steel plate, a stainless steel plate, an aluminum alloy plate, a titanium alloy plate, and a copper plate, Those formed into a predetermined shape by extrusion molding or other means can be appropriately used. Furthermore, a backing material such as polyethylene foam or glass wool sheet may be attached to the back surface of the exterior material as necessary for the purpose of preventing condensation, soundproofing, and fireproofing.

As described above, the protruding upper portion of the heat insulating backup material is a portion where the surface layer portion (upper half) at the lower end of the water extends to the lower side of the water. You may make it make a shaping | molding part fit. That is, in many side facing materials, on the substantially flat heat insulating layer, the eaves side molded portion is engaged with and connected to the ridge side molded portion, and the hanging portion is fixed on the heat insulating layer. Although the structure hold | maintained by the holding member of this is taken, a water flow direction is required without providing a hanging part by providing the site | part fitted to the said protrusion upper part as a water upper side (ridge side) shaping | molding part. The exterior materials adjacent to each other can be connected.
In addition, the exterior material in the above-mentioned prior invention (Japanese Patent Application No. 2017-57990) has a fixed piece portion along the heat insulating backup material on the water side of the face plate portion, and the water side opens to the water side. A horizontal groove, a water-side molded part with a fitting part that fits into the protruding upper part of the heat-insulating backup material, and can be engaged with the horizontal groove by folding back to the water side and extending the water side to the water side of the face plate part. Since it has the structure which has a water insertion part provided with an insertion part and the superposition | polymerization part superposed on the outer side of the said fitting part, you may make it use this exterior material.

Moreover, the eaves arabesque of this invention may be provided with the to-be-fixed part which protrudes further to the eaves end side rather than the said to-be-engaged part, and fixes the cover material which covers the upper surface of an eaves ridge.
The cover material is a member that covers the upper surface of various eaves, and is a member that prevents intrusion of snow and dust into the eaves. It is desirable that a slit hole be formed.
The eaves covering the upper surface with the cover material is not particularly limited in the shape of the bottom surface and both side surfaces as long as the drainage channel such as rainwater is provided therein. For example, PVC, polycarbonate, etc. Therefore, there is no particular limitation on the configuration and shape of the cover material covering the upper surface.

As described above, the fixed portion is a portion that fixes the cover material that protrudes further toward the eaves side than the engaged portion and covers the upper surface of the eaves hook. The above-mentioned “protruding further toward the eaves side than the engaged part” means that the fixed part protrudes more toward the eaves side than the engaged part.
In addition, this to-be-fixed part can be formed in a horizontal piece shape or a vertical piece shape, and can fix a cover material using fixing tools, such as a screw.

  As described above, the shape of the cover material and eaves is not particularly limited. However, as shown in the illustrated embodiment to be described later, the cover material and eaves are bent substantially inwardly at the front end of the eaves. In the case where a U-shaped engagement portion is provided and the eaves end of the eaves hook is engaged with the back side thereof, the substantially U-shaped engagement portion pulls the eave end of the eaves eaves from above. It can be held and bear the load of the eaves. That is, the cover material in this case also serves as an arm for holding the eaves tip of the eaves so as to be pulled.

As described above, the eaves arabesque of the present invention is a member having an attachment fixing portion, an engaged portion, and a support portion, and strength characteristics for preventing the eaves end of the heat insulating backup material from being bent downward and broken. However, the material and processing method are not particularly limited, but the attachment fixing portion, the engaged portion, and the support portion are each formed as a continuous material that is continuous in the length direction. This is desirable from the viewpoint of protecting the eaves.
In addition, this eaves arabesque is attached to the roof surface (roof structure) such as the exterior base, and does not drive the fixing tool from the side into the nose cover wall like the above-mentioned conventional saddle bracket, so it is easy to And it can attach firmly.
