Description

TECHNICAL FIELD The present disclosure relates to fixing brackets for a roof waterproof sheet, for example, for fixing a waterproof sheet to the roof of a building.

A waterproof layer is provided on the roof of various buildings. The waterproof layer is formed, for example, by laying a waterproof sheet made of vinyl chloride, a thermoplastic elastomer sheet, or the like on the roof (see Patent Documents 1 and 2, for example). In some cases, a raised portion called a parapet is formed on the roof.

JP-A-11-210180 JP-A-2018-90968

By the way, when laying the waterproof sheet on the roof, it is possible to use fixing metal fittings made of PVC-coated steel plates. That is, after fixing the fixture to the frame of the building, the waterproof sheet is laid, and the back side of the laid waterproof sheet is fused to the vinyl chloride layer of the fixture by heat or by welding with a solvent. When the waterproof sheet is a thermoplastic elastomer sheet, it can be similarly fixed by using a thermoplastic elastomer laminated steel plate.

Here, since the fixing metal fittings are formed to have a predetermined length in advance, a plurality of fixing metal fittings are usually arranged in the longitudinal direction at the construction site and fixed to the frame with screws. By using a plurality of fixing metal fittings, a joint formed by butting the end portions of the fixing metal fittings, that is, a butt joint portion is formed. Butt joints must be insulated to prevent the waterproof sheet from sticking. The reason for this is the difference in expansion and contraction of the waterproof sheet and fixing metal fittings due to the temperature difference between day and night and the change of season, and the decrease in expansion and contraction of the waterproof sheet due to the deterioration of the waterproof sheet over time. This is because the part will crack. If even a part of the waterproof sheet is cracked, water will leak from the crack, so the insulation treatment is an important treatment.

As an insulation treatment method, there is a method of attaching an insulating material to the surface of the terminal part of the fixing bracket (the surface on which the PVC layer is formed), but the on-site worker forgets to attach the insulating material. It is conceivable that As a countermeasure, it is conceivable to affix an insulating member in advance when shipping the fixture, but in such a case, the following problems occur.

That is, as the shape of the fixing bracket, for example, there is one that is bent into an L-shape so that it can be attached to the external corner of the roof. In order to reduce the number of types handled by the manufacturer and facilitate management, it is desirable to use a common fixing bracket for the outside corner and the end of the parapet.

However, there are portions at the ends of the parapet that do not require insulation. A specific example thereof will be described with reference to FIG. FIG. 8 shows a state in which the fixture 1 is fixed to the end of the parapet 102 and the waterproof sheet 200 is fused or welded to the fixture 1 . In the parapet 102 as well, the butt joints of the fixture 1 need to be insulated with the insulating member 4 , but if the lower end of the fixture 1 is insulated, the end of the waterproof sheet 200 will rise from the fixture 1 . , looks worse. Therefore, in the parapet 102, it is desired that only the lower end of the fixture 1 is not insulated. had to be pasted. In addition, if the lower end of the fixing bracket of the parapet is not insulated, there is a concern that the waterproof sheet will crack at the lower end. does not immediately lead to water leakage.

The present disclosure is made in view of this point, and the purpose thereof is to make the fixing metal fittings for fixing the waterproof sheet common to a plurality of parts on the roof, and to perform insulation treatment suitable for each part. It is to be

In order to achieve the above object, one aspect of the present disclosure can be premised on a fixing bracket for a roof waterproof sheet that is fixed to the roof frame of a building and to which the waterproof sheet is fused or welded. The roof waterproof sheet fixing bracket is provided on a horizontally long plate-shaped base material and on the base material so as to cover the side of the base material on which the waterproof sheet is laid, and is fused or bonded to the waterproof sheet. It comprises a coating layer to be welded, and an insulating member provided at a portion of the coating layer corresponding to the terminal portion of the base material and having non-bonding and non-welding properties with respect to the waterproof sheet. The insulating member has a non-fixed portion that is not fixed to one end portion of the coating layer in a direction perpendicular to the longitudinal direction of the base material.

According to this configuration, after a plurality of roof waterproof sheet fixing brackets are arranged and fixed along the exterior corner and inner corner of the roof, the waterproof sheet is laid, and the covering layer of each roof waterproof sheet fixing bracket is heated. The tarp can be secured to the roof by fusing or solvent welding. At this time, an insulating member is affixed to the ends of the fixtures for the rooftop waterproof sheet, so that the coating layer and the waterproof sheet are properly insulated, so that the waterproof sheet will not crack due to temperature changes or aging. occurrence is suppressed.

On the other hand, it is also possible to fix the fixtures for the roof waterproof sheet to a parapet on the roof. In this case, the fixtures for the rooftop waterproof sheet are placed so that the non-adhered part of the insulating member faces downward, and the lower end of the covering layer is fused to the waterproof sheet by bending or cutting the non-adhered part. or can be welded.

Further, the base material may be a member having a horizontal plate portion extending in the horizontal direction and a vertical plate portion extending downward from one end portion in the width direction of the horizontal plate portion. In this case, the coating layer can be provided from the other widthwise end portion of the horizontal plate portion to the lower end portion of the vertical plate portion. The insulating member can be provided over a portion of the coating layer corresponding to the other end in the width direction of the horizontal plate portion and the lower end portion of the vertical plate portion. The non-adhered portion is a portion that is not adhered to the portion of the coating layer corresponding to the lower end portion of the vertical plate portion.

According to this configuration, when fixing the fixing bracket for the roof waterproof sheet to the outside corner, the horizontal plate part is arranged along the upper surface of the outside corner, and the vertical plate part is arranged along the vertical surface of the outside corner. A plate can be arranged. Further, when fixing the roof waterproof sheet fixing bracket to the parapet, the horizontal plate portion can be arranged along the upper surface of the parapet, and the vertical plate portion can be arranged along the vertical surface of the parapet. Therefore, it is possible to use a common roof waterproof sheet fixing bracket for both the external corner portion and the parapet. When the parapet is used, the non-fixed portion of the insulating member is not fixed to the portion corresponding to the lower end of the vertical plate portion. Suitable insulation can be applied.

Also, the insulating member may be a tape having an adhesive layer. In this case, the adhesive layer can be adhered to the covering layer, and the non-adhered portion can be configured by adhering the non-adhered member to the adhesive layer.

According to this configuration, the insulating member can be easily constructed by attaching the tape to the covering layer, and the non-adhering portion can be easily constructed by attaching the non-adhering member to a part of the adhesive layer of the tape. can do.

Alternatively, the portion where the tape is folded back and the adhesive layers of the tape are adhered to each other may be used as the non-adhered portion. In this case, the non-fixed portion can be easily obtained simply by folding back the tape.

Also, the metal tape may be plastically deformable. According to this configuration, when insulation is required up to the edge of the covering layer, the shape of the metal tape can be maintained so as to cover the edge of the covering layer. On the other hand, if insulation of the edge of the covering layer is not required, the metal tape can be folded so as not to cover the edge of the covering layer.

As described above, since the insulating member has a non-adhering part, when the roof waterproof sheet fixing bracket is used in common for a plurality of parts on the roof, the non-adhering part can be used for each part. Suitable insulation can be applied.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail based on the drawings. It should be noted that the following description of preferred embodiments is essentially merely illustrative, and is not intended to limit the invention, its applications, or its uses.

(Embodiment 1)
1 and 2 show a roof waterproof sheet fixture 1 according to Embodiment 1 of the present invention. The fixing bracket 1 for the roof waterproof sheet is fixed to the external corner 101 of the building roof frame 100 shown in FIG. It is a member that can be used both when it is fixed to the parapet 102 and when the waterproof sheet 200 is fixed to the parapet 102 . The building is, for example, a house, a factory, a store, etc., and the roof structure 100 is made of, for example, concrete, steel material, wood, heat insulating material, or the like. The waterproof sheet 200 may be made of, for example, vinyl chloride or a thermoplastic elastomer such as polyethylene.

As shown in FIG. 1, the roof waterproof sheet fixture 1 includes a base material 2 elongated in the horizontal direction, a coating layer (resin layer) 3 covering the base material 2, and insulation between the waterproof sheet 200 and the coating layer 3. and an insulating member 4 for The lengthwise dimension of the rooftop waterproof sheet fixture 1 is not particularly limited, but can be, for example, 100 cm or more, and is set to 200 cm in this embodiment in consideration of portability.

The base material 2 is made of, for example, a steel plate, and has a horizontal plate portion 2a extending in the horizontal direction and a vertical plate portion 2b extending downward from one end portion in the width direction of the horizontal plate portion 2a. The horizontal plate portion 2a and the vertical plate portion 2b are formed integrally. For example, the horizontal plate portion 2a and the vertical plate portion 2b can be obtained by press-molding a single plate material. The angle formed by the horizontal plate portion 2a and the vertical plate portion 2b is substantially a right angle. The width direction of the lateral plate portion 2 a is the same as the width direction of the base material 2 . The horizontal plate portion 2a is placed on the upper surface of the external corner portion 101 and extends along the upper surface as shown in FIG. 4, and is placed on the upper surface of the parapet 102 as shown in FIG. It is the part that extends The vertical plate portion 2b is placed on the vertical surface of the external corner portion 101 as shown in FIG. 4 and extends along the vertical surface, and is placed on the vertical surface of the parapet 102 as shown in FIG. and extending along the longitudinal plane. In this embodiment, the widthwise dimension of the horizontal plate portion 2a is set longer than the vertical dimension of the vertical plate portion 2b. or the widthwise dimension of the horizontal plate portion 2a and the vertical dimension of the vertical plate portion 2b may be set to be the same.

The coating layer 3 is provided, for example, fixed to the base material 2 so as to cover the side of the base material 2 on which the waterproof sheet 200 is laid (also referred to as the front side). In this embodiment, the substrate 2 has the horizontal plate portion 2a and the vertical plate portion 2b, so the coating layer 3 extends from the other widthwise end portion of the horizontal plate portion 2a through one end portion to the vertical plate portion 2b. is continuously provided from the upper end portion to the lower end portion of the The thickness of the coating layer 3 is set significantly thinner than that of the base material 2 .

When the waterproof sheet 200 is made of vinyl chloride, the covering layer 3 is also made of vinyl chloride, and when the waterproof sheet 200 is made of thermoplastic elastomer, the covering layer 3 is also made of thermoplastic elastomer. The coating layer 3 can be fused or welded to the waterproof sheet 200 regardless of whether the coating layer 3 is vinyl chloride or a thermoplastic elastomer. When fusing, the waterproof sheet 200 is brought into close contact with the covering layer 3 while being melted by blowing hot air at 200° C. or higher to the covering layer 3 or the waterproof sheet 200 . When welding, the coating layer 3 is melted by adhering a solvent to the waterproof sheet 200 , and the waterproof sheet 200 is brought into close contact with the coating layer 3 . In other words, the coating layer 3 has at least one of the fusible properties and the fusible properties with respect to the waterproof sheet 200, and may have both the fusible properties and the fusible properties.

A fixing bracket 1 for a roof waterproof sheet can be constructed using a laminated steel plate in which a coating layer 3 is laminated on a base material 2 . A plurality of fixing holes 1a are provided at intervals in the longitudinal direction in portions corresponding to the horizontal plate portions 2a of the roof waterproof sheet fixing bracket 1. As shown in FIG. The fixing hole 1a is formed so as to penetrate the lateral plate portion 2a and the covering layer 3. As shown in FIG. When fixing the roof waterproof sheet fixing bracket 1 to the external corner 101 or the parapet 102, a fastening member A (shown in FIG. 3) such as a screw is inserted into the fixing hole 1a to secure the external corner 101 or the parapet 102. It can be fixed by screwing it into or hammering it in. The fixing structure of the roof waterproof sheet fixture 1 is not limited to the structure described above, and various fixing structures can be used.

The insulating members 4 are provided at portions corresponding to both ends (both ends in the longitudinal direction) of the base material 2 in the coating layer 3, respectively, and have non-adhesive and non-adhesive properties to the waterproof sheet 200. It is a member. Specifically, the insulating member 4 is composed of a tape in which a base material layer and an adhesive layer are laminated. Although the material of the base material layer is not particularly limited, it is a material that does not fuse and does not adhere to the waterproof sheet 200. For example, a material such as an aluminum alloy or stainless steel that undergoes plastic deformation and retains its shape after deformation. can be mentioned. In the case of an aluminum alloy, since the shape followability is higher than that of stainless steel, it is preferable in terms of good workability when attaching the coating layer 3 in close contact with the coating layer 3 . Further, by using a plastically deformable metal material as the base layer of the tape, the tape becomes a plastically deformable metal tape. The base layer of the tape may be paper, cloth, or the like, and is not limited to metal.

The adhesive layer of the tape is composed of an adhesive composition that exhibits adhesiveness to the coating layer 3 . This adhesive composition may be one used as an adhesive layer of a general craft tape.

The width direction of the insulating member 4 is the longitudinal direction of the fixing bracket 1 for roof waterproof sheet, and the width direction dimension of the insulating member 4 can be set to, for example, 10 mm or more, or 20 mm or more, and is particularly limited. However, it is sufficient that the dimensions are such that the occurrence of cracks in the waterproof sheet 200 due to temperature changes and aging is significantly suppressed.

The ends of the insulating member 4 in the width direction and the ends of the base material 2 are aligned so that the ends of the base material 2 in the coating layer 3 can be reliably covered with the insulating member 4 . The insulating member 4 has a first fixing portion 4a that is attached and fixed to a portion of the coating layer 3 corresponding to the horizontal plate portion 2a, and is attached to a portion of the coating layer 3 that corresponds to the vertical plate portion 2b. It has a second fixed portion 4b fixed in a state and a non-fixed portion 4c. The first fixing portion 4a is continuous from one end in the width direction of the lateral plate portion 2a of the covering layer 3 to a portion corresponding to the other end. The second fixing portion 4b is continuous from the upper end portion of the vertical plate portion 2b in the coating layer 3 to a portion corresponding to the vertical intermediate portion.

The first fixed portion 4a and the second fixed portion 4b are fixed to the coating layer 3 as described above, but the non-fixed portion 4c is not fixed to the coating layer 3. As shown in FIG. That is, when the direction perpendicular to the longitudinal direction of the base material 2 in the coating layer 3 is defined as the vertical direction, the non-fixed portion 4c is non-fixed to the lower end portion, which is one end portion thereof. The non-fixed portion 4c is continuous with the lower end portion of the second fixed portion 4b and has a length reaching the lower end portion of the vertical plate portion 2b of the coating layer 3 as shown in FIG. A dashed-dotted line indicated by symbol L indicates the boundary between the second fixed portion 4b and the non-fixed portion 4c, and the portion below the line L in FIG. 1 is the non-fixed portion 4c. The vertical dimension of the non-fixed portion 4c can be, for example, 10 mm or more.

The non-adhered portion 4c may be configured so as not to be adhered to the covering layer 3, and one example thereof is a configuration in which the non-adhered member is adhered to the adhesive layer of the tape. The non-adhesive member is a member such as a metal or resin film or sheet, paper or cloth that does not have tackiness and adhesiveness. Also, the non-adhered portion 4c may be configured by a portion where the adhesive layers are adhered to each other by folding back the tape. As a result, the adhesive layer of the tape is not exposed, so that it is not adhered to the covering layer 3 .

Since the non-fixed portion 4c is not fixed to the covering layer 3, the non-fixed portion 4c can be bent upward as shown in FIG. At this time, the non-fixed portion 4c rotates upward with the vicinity of the line L shown in FIG. 1 as the center of rotation. Since the insulating member 4 is composed of a plastically deformable metal tape, the shape of the insulating member 4 can be maintained in a state where the non-fixed portion 4c is bent upward (first posture). Similarly, the shape of the insulating member 4 can be maintained with the non-fixed portion 4c extended downward (second posture). No special tool is required for bending the non-fixed portion 4c, and it can be easily bent with fingers.

(Construction method)
First, the construction method for the external corner portion 101 shown in FIGS. 3 to 5 will be described. As shown in FIG. 3, after arranging a plurality of fixing metal fittings 1 for a roof waterproof sheet in the longitudinal direction and placing them on an external corner portion 101, a fastening member A is inserted into the fixing hole 1a of each fixing metal fitting 1 for a rooftop waterproof sheet. , to fix each roof waterproof sheet fixture 1 by screwing it into the external corner 101 . At this time, the longitudinal end portions of the fixing metal fittings 1 for the roof waterproof sheet adjacent to each other are butted against each other. The non-fixed portion 4c of the insulating member 4 is extended downward as shown in FIG. Keep In FIG. 3, the insulating members 4 are provided at both ends in the longitudinal direction of the fixing bracket 1 for the roof waterproof sheet, but the insulating member 4 is not limited to this, and only one end of the fixing bracket 1 for the roof waterproof sheet is provided. 4 may be provided.

After that, as shown in FIGS. 4 and 5, a waterproof sheet 200 is laid and fused or welded to the covering layer 3 of the fixture 1 for roof waterproof sheet. At this time, since the entire portion of the coating layer 3 corresponding to the terminal portion of the base material 2 is insulated from the waterproof sheet 200, the waterproof sheet 200 is not covered by the portion of the coating layer 3 corresponding to the terminal portion of the base material 2. Fused and not welded to the whole.

Next, a construction method for the parapet 102 shown in FIGS. 6 to 8 will be described. As shown in FIG. 6, after a plurality of rooftop waterproof sheet fixing brackets 1 are arranged in the longitudinal direction and placed on a parapet 102, the fastening member A is inserted through the fixing hole 1a of each rooftop waterproof sheet fixing bracket 1, and the parapet is mounted. 102 are screwed in to fix each fixture 1 for roof waterproof sheet. At this time, the longitudinal end portions of the fixing metal fittings 1 for the roof waterproof sheet adjacent to each other are butted against each other. Also, the non-fixed portion 4c of the insulating member 4 is bent upward as shown in FIG. Since the insulating member 4 retains its shape, it is not necessary to fix the non-fixed portion 4c separately. By bending the non-fixed portion 4c upward, the portion of the coating layer 3 corresponding to the lower end portion of the vertical plate portion 2b can be exposed. Alternatively, the non-fixed portion 4c may be cut without bending the non-fixed portion 4c. In FIG. 6, the insulating member 4 is provided at both ends in the longitudinal direction of the fixture 1 for the roof waterproof sheet, but the insulating member 4 is not limited to this, and only one end of the fixture 1 for the roof waterproof sheet is provided. 4 may be provided.

After that, as shown in FIGS. 7 and 8, a waterproof sheet 200 is laid and fused or welded to the covering layer 3 of the fixture 1 for a rooftop waterproof sheet. At this time, since the portion of the coating layer 3 corresponding to the lower end of the vertical plate portion 2b is not insulated, the waterproof sheet 200 is fused or welded to the portion of the coating layer 3 corresponding to the lower end of the vertical plate portion 2b. be done. As a result, the lower end of the waterproof sheet 200 does not rise. In addition, by folding the non-adhered portion 4c upward, the tape becomes a state in which two sheets are overlapped, and the thickness is increased. This suppresses thermal deterioration of the coating layer 3 due to hot air during fusion bonding.

If the parapet 102 does not insulate the lower end of the roof waterproof sheet fixture 1, there is a concern that the waterproof sheet 200 may crack at the lower end. In addition, even if a crack appears, it does not immediately lead to water leakage.

(Effect)
As described above, according to the first embodiment, after arranging and fixing a plurality of roof waterproof sheet fixing brackets 1 along the exterior corner 101 of the roof, the waterproof sheet 200 is laid and fixed for each roof waterproof sheet. The waterproof sheet 200 can be firmly fixed to the roof by fusing with heat or with a solvent to the coating layer 3 of the fitting 1 . At this time, since the insulating member 4 is fixed to the terminal part of the fixing bracket 1 for the rooftop waterproof sheet and the coating layer 3 and the waterproof sheet 200 are appropriately insulated, the waterproof sheet may be damaged due to temperature changes and aging. The occurrence of cracks to 200 is suppressed.

On the other hand, it is also possible to fix the roof waterproof sheet fixture 1 to a parapet 102 on the roof. In this case, the roof waterproof sheet fixture 1 is placed so that the non-fixed portion 4c of the insulating member 4 faces downward, and by bending the non-fixed portion 4c upward, the lower end of the coating layer 3 is attached to the waterproof sheet. It can be fused or welded to 200 for better appearance.
