However, in the above-mentioned method 1, Patent Document 1, it is practically impossible to completely prevent rainwater from entering from the corners due to a capillary phenomenon or the like, and is it possible to obtain an equivalent folding process? Whether or not it depends largely on the skill of the field worker.
Moreover, in said 2 method and patent document 2, since an opening part, a roof material, and a discard board are each comprised with a metal plate material and its shaping | molding processing material, a clearance gap is formed in those combined parts, and especially a some plurality A gap was formed in the combination part of the discarded plates, and rainwater leaked from these gaps.
Therefore, an object of the present invention is to propose a storage structure for an opening formed on a roof surface that can solve the above-described problems and can form a structure excellent in workability, workability, and rain performance.

The present invention has been proposed in view of the above, and a plate-like material as a waterproof layer provided with a hole is disposed on the periphery of the opening provided in the roof, and is transparent so as to cover the hole of the waterproof layer. It is a storage structure in which a light material is disposed, and the light-transmitting material is formed by integrally assembling an upper frame body or a frame around the light-transmitting material main body or the periphery thereof, and the waterproof layer corresponds to an opening. Only one plate-like material having a hole or a plurality of plate-like materials are extended from the periphery of the opening, and adjacent plate-like materials are integrally connected via a water stop material, The edge located at the periphery of the opening is the inner edge, the edge in the opposite direction is the outer edge, and among the inner edges of the waterproof layer, the inner edge located at the edge of the opening and the water-side edge is the above-mentioned The outer edge of the waterproof layer is sandwiched between the light-transmitting material and the base of the periphery of the opening with an elastic water-stopping material interposed therebetween. Located on the back side of the roofing material placed on the side, the waterside outer edge of the waterproof layer placed on the waterside of the opening is formed on the ridge side of the roofing material placed on the eaves side of the outer roofing material. The present invention relates to a storage structure for an opening formed on a roof surface, which is characterized by extending to a part .

The present invention also proposes a storage structure for an opening formed on the roof surface , wherein the plate-like material is provided with a water return in the storage structure.

  Furthermore, the present invention proposes a storage structure characterized in that in the storage structure, the edge of the plate-like material is sandwiched by interposing an elastic water stop material.

In the opening storage structure formed on the roof surface of the present invention, a plate-like material is arranged as a waterproof layer in the opening direction and on the water side, and the edge (inner edge) located on the opening side is a transparent body. In addition, since it is held in a watertight state at the base of the periphery of the opening, it is possible to prevent formation of a gap through which rainwater enters.
Therefore, the storage structure of the present invention can form a structure with excellent rain performance in a configuration in which an opening such as a top light is provided on the roof.
Furthermore, since the water-stopping material having elasticity is interposed, the holding is brought into pressure contact and the water-tight state is maintained, so that more reliable water-tightness and water-stopping properties can be obtained.

  In particular, when the plate-like material is provided with a water return, it is possible to prevent backflow of rainwater and to prevent rainwater from entering the back side.

In the following description, the “translucent material” is referred to as “transparent”, and the “main body” of the translucent material is referred to as “translucent material”.
The present invention is a storage structure of an opening provided on a roof as a toplight or the like, and the shape of the opening is not limited in any way. A transparent body is faced so as to cover the opening, and a plate-like material is disposed as a waterproof layer on the periphery of the opening, and is located in the direction of the opening of the plate-like material and the edge on the water side. The edge to be held is sandwiched between the transparent body and the base of the periphery of the opening.

As the transparent body, a light-transmitting material such as glass, a transparent acrylic plate, and glass with mesh can be used, and is not particularly limited. You may make it arrange | position the permeation | transmission material for receiving dew condensation on the back surface side like the Example mentioned later.
Further, a fixed body integrated type transmission body (made of synthetic resin) or a frame (upper frame body) that integrally holds the periphery of a plate-like light transmitting material may be assembled as the transmission body.

The base of the periphery of the opening (hereinafter referred to as the peripheral base to distinguish it from the roof base) receives and supports the plate-like material disposed on the periphery of the opening. Furthermore, in the case of a new installation, RC, wooden structure, steel frame, etc. are not limited, and in the case of an existing roof, various roofs such as waterproof roofs, metals, tiles, etc. can be handled. Of course, the case where a new opening is constructed in the existing roof is also included. Further, a foam heat insulating material (polystyrene or the like) may be provided on the surface.
As described above, the peripheral base supports the back surface of the plate-like material. In the case of a steel structure, the purlin or the rafter may receive the back surface of the sheet material, or the purlin or the rafter. When a hard board (underlying material) is laid on the upper surface, the boat receives and supports the back surface of the plate-like material. Further, in the case of RC construction, the concrete base surface receives and supports the back surface of the plate-like material.

As the peripheral base, a frame-like frame (lower frame) that supports the lower edge around the transmission body may be disposed around the opening, and the frame is generally rectangular. Depending on the permeation body formed in the above, it may be arranged on its four sides (shift direction, flow direction), and the configuration is not particularly limited.
Further, the frame body (lower frame body) as the peripheral base is integrally connected with a frame (upper frame body) supporting the upper edge around the transmission body with a screw or the like as in the illustrated embodiment described later. You may do it.

The plate-like material is arranged as a waterproof layer in the present invention, and only one plate-like material having a hole corresponding to the opening may be used, or a plurality of plate-like materials may be used. The plate-like members may be radially extended from (periphery) of the opening, and adjacent plate-like members may be integrally connected via a water stop material.
As this plate-like material, the same material as the roof material for the outer periphery and the roof material of the general part which will be described later is a surface decorative steel plate, laminated steel plate, plated steel plate, stainless steel plate, aluminum alloy plate, titanium alloy plate, copper plate, brass plate. In addition, a known metal material such as a lead plate is appropriately used, and may be formed (molded) by roll molding, press molding, or a combination of both as required, and the material thickness is not particularly limited. Absent.
Further, as a mode that does not require a water-stopping material, a flexible water-impermeable plastic film sheet, such as a vinyl chloride-based or olefin-based sheet, or an elastic silicone rubber sheet or butyl rubber sheet may be used. . It may be clamped in a pressure-contact manner. Alternatively, other known waterproof sheets may be used, or a composite waterproof sheet having a structure in which a core or a reinforcing body such as a polycloth, a felt layer, or a glass fiber base fabric is laminated on a resin layer such as polyvinyl chloride, and particularly fireproof (fireproof) performance. A composite waterproof sheet with excellent resistance is desirable. The composite waterproof sheet having a structure in which a core or a reinforcing body is laminated on the resin layer has almost no expansion / contraction deformation (dimensional change) in the planar direction, and is resistant to physical stress, particularly stretching in the planar direction and compression in the thickness direction. There is an advantage that slack or the like hardly occurs on the metal layer.

Edges (inner edges) located at the edge of the plate-shaped material opening and the water-side edge are held in a water-tight manner at the permeator and the peripheral base, but preferably through a water-stopping material. By close contact (preferably using a water-stopping material having elasticity), a gap for water to enter is not formed, and high rain performance can be obtained. In addition, when using the sheet material which consists of the said water-impermeable elastic body as a plate-shaped material, it is not necessary to interpose a water stop material.
The water-stopping material used here is not particularly limited, but for example, a water-stopping material having elasticity such as butyl rubber, ethylene / propylene rubber (EPDM), silicone rubber or the like can be suitably used. In the case of using an elastically deformable fixed water-stopping material such as solid or hollow, it may be solid or hollow, or is not limited to a fixed material, and may be a liquid-type amorphous material and has a function as an adhesive. It may be a thing. The butyl rubber, silicone rubber and the like are non-water-permeable (water-proof) materials and have elasticity, so that they are preferable in that they can be clamped (held) in a water-tight manner by pressure contact.

Moreover, since the other edge (outer edge) of this plate-shaped material is located on the back surface of the roof material arranged outside the opening, water can be submerged at least from the outer edge side of the plate-shaped material. Absent.
Furthermore, a water return may be provided on the outer edge of the plate-like material to prevent backflow of rainwater. This water return may be formed with a plurality of fin-like protrusions as shown in the illustrated embodiment described later, and is not particularly limited.

The roofing material used on the outside (outer periphery) of the opening may be partially cut off from the roofing material of the general part as necessary, or may be molded for the outer periphery from the viewpoint of allocation or the like. Good. Further, the end (opening side) of the roof material used outside the opening may be attached to the transmission body (upper frame body) or may be sandwiched in the same manner as the sheet material. It may be held by a ledge (illustrated “reinforcing frame 5”).
As such a roof material for the outer periphery and the roof material for the general part, a known metal such as a surface decorative steel plate, a laminated steel plate, a plated steel plate, a stainless steel plate, an aluminum alloy plate, a titanium alloy plate, a copper plate, a brass plate, a lead plate, etc. A material or the like may be used as appropriate, and may be formed (molded) by roll molding, press molding, or a combination of both as necessary, and the material thickness is not particularly limited.

A plate-like material 7 made of a metal plate material is disposed around the opening A. The annular glass packing 3a and the upper frame 3 are disposed only in the direction of the translucent material 4 and the edge on the water side, and are not disposed on the water side.
The peripheral base in this embodiment is composed of a lower frame 2 fixed to a roof base 1 constructed by laying a field material 12 on a frame 11 combined with C-shaped steel.
The inner edge of the plate-like material 7 is sandwiched between the transmission body (upper frame body 3) and the peripheral base (lower frame body 2) at the edge of the opening A located in the direction of the shift and on the water side. However, on the underwater side of the opening A, the transmissive body is in contact with the plate-shaped material 7D with a thin-layer packing material 8d which is an elastic molded body on the back surface of the translucent material 4.

  The lower frame body 2, the upper frame body 3, and the plate-like material 7 are disposed around the periphery of the opening A. In the following description, D is added to the reference numeral for the portion of the opening A located on the water side.

The lower frame body 2 constituting the peripheral base is an annular frame facing the lower edge around the translucent material 4.
The upper frame 3 constituting the transmission body is a frame-like frame (glass pressing edge) facing from the upper direction edge of the translucent material 4 and the water-side edge, and the annular glass packing 3a and the sealing 3d. The edge of the translucent material 4 is held in a sandwiched manner.
In addition, although the annular frame was used as the lower frame 2 and the frame-shaped frame was used as the upper frame 3, the three sides of the translucent material 4, that is, the three sides of the water-side edge and the edge in the carry direction, were used. It is good also as a structure which combined three member each distribute | arranged, and the cross-sectional structure in that case will also be the same as that of the illustrated embodiment.

The plate-like material 7 is a single plate-like material having a hole having a shape corresponding to the opening A, and an adhesive layer may be appropriately provided on the back surface side. The upper edge 3 (transparent body) and the lower frame 2 (periphery base) are connected via a water-stopping material (butyl rubber sheet) 70a having elasticity. Screwed in a state of being sandwiched between and. For this reason, the sandwiched portion is in a pressure contact state and is held in a watertight state. A fin-like water return 71 is provided so as to protrude to the surface side at the other edge (outer edge) on the water side and the outer edge in the carry direction.
This will be described with reference to an enlarged embodiment shown in FIG .
The lower frame body 2 is fixed to the opening A on the roof base 1 with a mounting screw 20, and a portion other than the opening A (outside of the periphery) is a polystyrene foam plate and a hat-type rafter as a backup material 6. Support member 6 'is fixed. The upper surface of the fixed lower frame body 2 provided with anti-slip projections supports the inner edge of the plate-like material 7 on the opening side A, and below the translucent material 4 via the annular glass packing 3a. Support the rim. In this state, the upper horizontal piece of the upper frame body 3 faces the upper edge of the translucent material 4 in a pressing manner via the annular glass packing 3a, and the lower horizontal piece of the upper frame body 3 is sealed.
