Description

[Technical Field]

[0001] The present invention relates to a parapet surrounding structure for a building. [Background technology]

[0002] A common rainwater protection measure for balconies and flat roofs is to lay a waterproof sheet continuously from the top of the floor to the top of a parapet around the perimeter of the floor, with part of the waterproof sheet fixed around the spandrel supports that rise from the top of the parapet. A number of spandrel supports are arranged at intervals along the length of the parapet in a plan view, with a spandrel wall attached to each support, and a handrail attached to the top of the spandrel.

[0003] However, with the conventional structure for fixing the waterproof sheet to the top of the parapet, the number of steps required for maintenance such as repairing the waterproof sheet is large, and the amount of work required for construction is a major issue. This issue will be explained with reference to Figures 1 and 2.

[0004] FIG. 1 is a longitudinal cross-sectional view of an example of a conventional parapet surrounding structure, and FIG. 2 is a diagram illustrating the process of repairing and constructing a waterproof sheet.

[0005] As shown in Figure 1, in a conventional balcony parapet peripheral structure 50 (an example of a parapet peripheral structure for a building), the floor material of a balcony 10 is supported on beams 11, which are structural members of the building, with a parapet 13 provided around the periphery of floor surface 12 of the floor material, and spandrel support columns 20 erected from the top edge 13a of the parapet 13. In a plan view, multiple spandrel support columns 20 are arranged in the longitudinal direction of the parapet 13, and a spandrel wall 25 is attached to each spandrel support column 20, with a handrail 27 attached to the top edge of the spandrel wall 25.

[0006] A continuous waterproof sheet 30 is laid from the floor 12 of the balcony 10 to the top 13a of the parapet 13, and one end 32 of the waterproof sheet 30 is arranged around the waist wall support 20 at the top 13a of the parapet 13, and one end 32 of the waterproof sheet 30 is fixed from above by support fittings 16 around the waist wall support 20, and a fascia 17 is installed on top of the support fittings 16.

[0007] The illustrated parapet peripheral structure 50 shows an example in which a solar power generation panel 40 is attached to the outdoor side of the waist wall 25.

[0008] In the conventional parapet peripheral structure 50 shown in Figure 1, when carrying out repair and construction of the waterproof sheet 30, as shown in Figure 2, the handrail 27 is dismantled in the X1 direction, the solar power generation panel 40 is dismantled in the X2 direction, the fascia 17 is dismantled in the X3 direction, the support accessory 16 is dismantled in the X4 direction, and the waist wall support 25 is dismantled, and then the waterproof sheet 30 is repaired.This requires an extremely large amount of labor for dismantling, and the construction effort becomes an issue.

[0009] For the above reasons, in the parapet surrounding structure of a building where a parapet is provided around the periphery, such as the floor surface of a balcony or the roof surface of a flat roof, and a continuous waterproof sheet is laid from the floor surface or roof surface to the parapet, there is a need for a parapet surrounding structure of a building that reduces the construction work required when repairing and installing the waterproof sheet.

[0010] Patent Document 1 proposes a dry waterproofing structure for the boundary between an exterior wall and an outdoor waist wall of a balcony, etc. In this dry waterproofing structure, the waist wall is made of a balcony waist wall, and vertical joints between the exterior wall surface materials are arranged so that metal fittings pass through, and the vertical joints are connected on both the top and bottom sides sandwiching an elastic water-stop material sandwiched between the exterior wall base part of the metal fittings and the exterior wall surface, and dry joint water-stop material is installed in the exterior wall vertical joint, and dry drainage guides are provided that extend above and below the connecting part and further extend onto the waterproof sheet on the balcony floor, with the lower end of the joint water-stop material protruding into the drainage guide, so that water stopped by the joint water-stop material is guided into the guide and drains through the connecting part onto the waterproof sheet on the balcony floor. [Prior art documents] [Patent documents]

[0011] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-256508 Summary of the Invention [Problem to be solved by the invention]

[0012] The dry waterproofing structure described in Patent Document 1 allows for easy dry construction to achieve watertightness between the upper surface of the outer wall edge of an outdoor spandrel wall such as a balcony and the outer wall surface, and also allows for a solid dry waterproofing of that section when a vertical joint in the outer wall is provided so as to pass through the outdoor spandrel wall. However, Patent Document 1 does not disclose any means for addressing the above-mentioned problem, i.e., reducing the labor required for repairing and installing a waterproof sheet in the structure around the parapet of a building.

[0013] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a parapet peripheral structure for a building in which a parapet is provided around the periphery, such as the floor surface of a balcony or the roof surface of a flat roof, and a continuous waterproof sheet is laid from the floor surface or roof surface to the parapet, in which the construction work required for repairing the waterproof sheet is reduced. [Means for solving the problem]

[0014] In order to achieve the above object, one aspect of the parapet surrounding structure of a building according to the present invention is as follows: A parapet is installed on the periphery of the balcony floor or roof of a building. A continuous waterproof sheet is arranged from the floor surface or the roof surface to the top edge of the parapet, A coping is attached to the top end so as to sandwich a part of the waterproof sheet, A first spandrel support column fixed to a structural member of the building below the parapet is erected on the outdoor side of the top edge of the parapet, The parapet is characterized in that a plurality of first spandrel support columns are attached at intervals along the longitudinal direction of the parapet in a plan view, a first spandrel wall is attached to the plurality of first spandrel support columns, and a handrail is attached to the first spandrel wall.

[0015] According to this aspect, a first waist wall support pillar fixed to a structural member of the building below the balcony or roof parapet is erected on the outdoor side of the top of the parapet, and a first waist wall is attached to this first waist wall support pillar, and a handrail is attached to the first waist wall.This means that the top of the parapet to which part of the waterproof sheet is fixed is separated from the first waist wall support pillar, which saves the labor required to disassemble the first waist wall support pillar and support accessories when renovating or constructing the waterproof sheet, and reduces the construction work required when renovating or constructing the waterproof sheet.

[0016] Here, "structural members of a building" includes beams supporting balconies and flat roofs, beams between floors, columns supporting beams, etc. Also, roofs with parapets around the perimeter of the roof surface include flat roofs, butterfly roofs, and sheath roofs.

[0017] Another aspect of the parapet surrounding structure of the building according to the present invention is as follows: A parapet is installed on the periphery of the balcony floor or roof of a building. A continuous waterproof sheet is arranged from the floor surface or the roof surface to the top edge of the parapet, A base jig is attached to the top end so as to sandwich a portion of the waterproof sheet, A first spandrel support column fixed to a structural member of the building below the parapet stands on the outdoor side of the top edge of the parapet, and a second spandrel support column stands directly above the parapet and is spaced apart from the top edge of the parapet and is connected to a horizontal tie member that is continuous with the first spandrel support column, and the first spandrel support column, the horizontal tie member, and the second spandrel support column form a crank-type spandrel support column. A plurality of crank-type spandrel wall supports are attached at intervals along the longitudinal direction of the parapet in a plan view, a first spandrel wall and a second spandrel wall are attached to each of the plurality of first spandrel wall supports and second spandrel wall supports, and a handrail is attached to at least the second spandrel wall.

[0018] According to this aspect, a first waist wall support column fixed to a structural member of the building below the balcony or roof parapet stands on the outdoor side of the top of the parapet, and a second waist wall support column stands directly above the parapet via a horizontal tie member that is continuous with the first waist wall support column and is located at a position away from the top of the parapet, and a crank-type waist wall support column is formed by the first waist wall support column, the horizontal tie member, and the second waist wall support column, and the first waist wall and second waist wall are attached to the first waist wall support column and the second waist wall support column, respectively, and a handrail is attached to at least the second waist wall, so that the top of the parapet to which part of the waterproof sheet is fixed is separated from the second waist wall support column (including the crank-type waist wall support column), which eliminates the labor required to disassemble the crank-type waist wall support column and support accessories when renovating or constructing the waterproof sheet, thereby reducing the construction effort required for renovating or constructing the waterproof sheet.

[0019] Another aspect of the parapet surrounding structure of the building according to the present invention is as follows: A support bracket for supporting the second waist wall support is interposed between the second waist wall support and the base jig.

[0020] According to this aspect, a support bracket supporting the second waist wall support is interposed between the second waist wall support that forms the crank-type waist wall support and the base jig, so that the second waist wall support can be supported by the support bracket connected to the top edge of the parapet, and the crank-type waist wall support can be maintained in a stable position.

[0021] In this embodiment, a portion of the waterproof sheet is attached to the top of the parapet using a base jig, and a support bracket is attached on top of the base jig.Therefore, when renovating the waterproof sheet, the support bracket can be removed from the crank-type waist wall support and the base jig can be removed to renovate the waterproof sheet, so the labor required for the renovation work does not increase significantly.

[0022] Another aspect of the parapet surrounding structure of the building according to the present invention is as follows: A first solar power generation panel is installed on the outdoor side of the first waist wall.

[0023] According to this aspect, when there is only a first waist wall, the first solar power generation panel is installed on the outdoor side of the first waist wall, making it an environmentally friendly building that can effectively utilize sunlight, a natural energy source.

[0024] Another aspect of the parapet surrounding structure of the building according to the present invention is as follows: A first solar power generation panel and a second solar power generation panel are installed on the outdoor side of both the first and second spandrel walls, respectively.

[0025] According to this aspect, when there are both a first waist wall and a second waist wall, by installing a first solar power generation panel and a second solar power generation panel on the outdoor side of each wall, the mounting area of ​​the solar power generation panels can be increased, and sunlight can be effectively utilized even if the balcony or flat roof space is small, resulting in an environmentally friendly building that can make even more effective use of sunlight. [Effects of the Invention]

[0026] As can be understood from the above explanation, the parapet surrounding structure of a building of the present invention can reduce the construction work required for repairing and constructing a waterproof sheet in a parapet surrounding structure of a building, such as a balcony or flat roof, where a parapet is provided around the periphery of the floor and a continuous waterproof sheet is laid from the floor to the parapet.

[0028] Hereinafter, an example of a parapet surrounding structure for a building according to an embodiment will be described with reference to the accompanying drawings. Note that in this specification and drawings, substantially identical components will be designated by the same reference numerals, and redundant explanations may be omitted.

[0029] [Parapet surrounding structure of the building according to the embodiment] An example of a parapet surrounding structure of a building according to an embodiment will be described with reference to Figures 3 to 8. Here, Figure 3 is a vertical cross-sectional view of an example of a parapet surrounding structure of a building according to an embodiment, and Figure 4 is an enlarged view of part IV in Figure 3. Figures 5 to 7 are process diagrams illustrating the repair and construction of a waterproof sheet in the parapet surrounding structure shown in Figure 3, respectively.

[0030] Below, we will explain the parapet surrounding structure of a balcony with reference to each figure, but the parapet surrounding structure of the embodiment may also be applied to parapets installed on roofs other than balconies, such as flat roofs, butterfly roofs, and gable roofs.

[0031] The parapet surrounding structure 80 shown in Figures 3 and 4 is a structure that defines the relationship between the waterproof sheet 30 to which a portion is fixed in the parapet 13 provided on the periphery of the floor surface 12 of the balcony 10 of a building, and the spandrel support columns 62, 64 attached around the parapet 13.

[0032] The balcony 10 is supported by beams 11 (an example of a structural member) located below it, with flooring laid above the beams 11 and a waterproof sheet 30 laid (disposed) above the floor surface 12, which is the upper surface of the flooring. The waterproof sheet 30 is disposed so as to extend continuously from the floor surface 12 to the top edge 13a of the parapet 13.

[0033] The spandrel wall support in the illustrated example is a crank-type spandrel wall support 60, which has a fixing member 68 fixed to the beam 11, a first spandrel wall support 62 erected from the fixing member 68 and arranged on the outdoor side of the top edge 13a of the parapet 13, a second spandrel wall support 64 erected directly above the parapet 13 and away from the top edge 13a of the parapet 13, and a horizontal connecting member 66 connecting the first spandrel wall support 62 and the second spandrel wall support 64 horizontally.

[0034] In the longitudinal direction of the parapet 13 in a plan view, multiple crank-type waist wall supports 60 are attached at intervals to the beams 11, the first waist wall 25A is attached to multiple first waist wall supports 62, and the second waist wall 25B is attached to multiple second waist wall supports 64, and handrails 27 are attached to the top ends of the first waist wall 25A and the second waist wall 25B.

[0035] One end 32 of a waterproof sheet 30 is placed on the top 13a of the parapet 13, and a base jig 18 is placed over the one end 32, and the base jig 18 and the one end 32 of the waterproof sheet 30 are fixed to the top 13a of the parapet 13 via fasteners.

[0036] There is a gap between the base jig 18 and the second waist wall support column 64, which are separated vertically from each other, and a support bracket 70 that supports the second waist wall support column 64 from below is fitted into this gap. The lower end of the fitted support bracket 70 is fixed to the top of the base jig 18 with fasteners such as screws or bolts, and the top of the support bracket 70 is fixed to the bottom of the second waist wall support column 64 via fasteners such as screws or bolts. The base jig 18 is covered with a head board 17, which has a recess (not shown) into which the head board 17 is fitted while the support bracket 70 is inserted, and the head board 17 is then installed on the base jig 18.

[0037] Here, the illustrated example has a support bracket 70 that supports the second waist wall support 64 from below, but even if the support bracket 70 is not present, if the so-called cantilever structure of the crank-type waist wall support 60 is stable, then installation of the support bracket 70 is not necessary.

[0038] A first solar power generation panel 40A and a second solar power generation panel 40B are installed on the outdoor side of the first waist wall 25A and the second waist wall 25B, respectively.

[0039] In this way, by providing different waist walls 25A, 25B at two positions on the outdoor and indoor sides of the balcony 10 and installing specific solar power generation panels 40A, 40B on each waist wall 25A, 25B, the mounting area for the solar power generation panels can be increased, contributing to the creation of an environmentally friendly building that makes it possible to effectively utilize sunlight even if the balcony 10 space is small.

[0040] Here, the photovoltaic panels 40A, 40B may be building integrated photovoltaic panels (BIPV (Building Integrated Photovoltaics)) in which the photovoltaic panels 40A, 40B are integrated with the waist walls 25A, 25B.

[0041] Next, a repair construction method for the waterproof sheet 30 in the parapet surrounding structure 80 will be outlined with reference to Figs.

[0042] First, as shown in Figure 5, the fascia 17 including the joint fascia 17a is removed from the base jig 18 in the Y1 direction, and as shown in Figure 6, the support bracket 70 is removed from the second waist wall supports 64 above and below it and from the base jig 18 in the Y2 direction.

[0043] Finally, as shown in Figure 7, by removing the base jig 18 from the top 13a of the parapet 13 in the Y3 direction, the waterproof sheet 30, which is laid continuously from the floor surface 12 to the top 13a of the parapet 13, can be removed in the Y4 direction and repaired.

[0044] In this way, in the illustrated example of the parapet peripheral structure 80, the top 13a of the parapet 13 to which a portion 32 of the waterproof sheet 30 is fixed is completely separated from the two first and second waist wall supports 62 and 64 of the crank-type waist wall support 60, and the second waist wall support 64, which is located directly above the top 13a of the parapet 13, is supported by a support bracket 70 that was retrofitted onto the top 13a.Therefore, when renovating and constructing the waterproof sheet 30, it is not necessary to dismantle many components, such as the handrails 27, the solar panels 40, and the support accessories and waist wall supports, as in the conventional parapet peripheral structure 50 shown in Figure 2, thereby reducing the amount of work required for construction.

[0045] Next, another example of a parapet peripheral structure according to the embodiment will be described with reference to Figures 8A and 8B. Here, Figure 8A is a vertical cross-sectional view of another example of a parapet peripheral structure of a building according to the embodiment, and Figure 8B is an exploded view of the other example of the parapet peripheral structure shown in Figure 8A.

[0046] The parapet surrounding structure 90 in the illustrated example differs from the parapet surrounding structure 80 in that, instead of the crank-type waist wall support 60, it has a straight-type waist wall support 60A (more specifically, it is L-shaped, but is considered straight in order to contrast it with the crank-type) which has a fixing member 68 connected to the beam 11 and a first waist wall support 62 erected upward from the fixing member 68 and arranged on the outdoor side of the parapet 13.

[0047] In the longitudinal direction of the parapet 13 when viewed from above, multiple straight-type waist wall supports 60A are attached at intervals to the beams 11, and the first waist wall 25A is attached to multiple first waist wall supports 62, and a handrail 27 is attached to the top end of the first waist wall 25A.

[0048] As with the parapet peripheral structure 80, a first solar power generation panel 40A is installed on the outdoor side of the first spandrel support 62.

[0049] As is clear from Figure 8A, the straight-type spandrel support 60A does not have a second spandrel support disposed directly above the parapet 13, and therefore no other components exist above the coping 17 that covers the top edge 13a of the parapet 13. Therefore, when repairing the waterproof sheet 30, it is not necessary to remove the support brackets 70, etc., which further reduces the amount of work required when repairing the waterproof sheet 30.

[0050] Furthermore, the parapet peripheral structure 90 is also equipped with the solar power generation panels 40A, which contributes to the creation of an environmentally friendly building that makes effective use of sunlight.

[0051] It should be noted that the present invention is not limited to the configurations shown here, and other embodiments may be possible in which other components are combined with the configurations described in the above embodiments. In this regard, the present invention can be modified within the scope of the present invention, and can be appropriately determined depending on the application form. [Explanation of symbols]
