Problems to be Solved by the Invention

[0004] However, in the above prior art, the wall bottom partition member is only attached to the water-stopping member by a fastening member, and there is room for improvement from the viewpoint of stably supporting the wall bottom partition member, that is, the partition portion.

[0005] In consideration of the above facts, an object of the present invention is to obtain a waist wall partition structure of a building that can stably support the partition portion of the waist wall.

Means for Solving the Problems

[0006] The parapet trim structure of a building according to the first embodiment comprises: a parapet frame that constitutes a part of the parapet frame structure and extends in the building height direction and to which an exterior wall material is attached; a parapet trim bracket attached to the lower side of the parapet frame in the building height direction; a lower parapet trim attached to the outer surface of the parapet trim bracket and positioned so as to overlap with the lower part of the parapet frame in the building height direction when viewed from the thickness direction of the exterior wall material, and having a lower extension that extends from the parapet frame side to the outside; an upper parapet trim attached to the lower part of the parapet frame in the building height direction above the lower parapet trim in the building height direction, and having an upper extension that extends from the parapet frame side to the outside and whose tip is locked to the tip of the lower extension; a supporting frame comprising a connecting piece joined to the parapet frame, and an extending piece that extends from the connecting piece to the outside and supports the upper extension from the lower side in the building height direction.

[0007] In the first embodiment of the building's parapet wall trim structure, a parapet wall frame, which constitutes part of the parapet wall's structural frame, extends in the building's height direction. Exterior wall material is attached to this parapet wall frame, thereby forming part of the parapet wall's surface. A parapet wall trim bracket is attached to the lower side of the parapet wall frame in the building's height direction.

[0008] The lower part of the parapet trim is attached to the outer surface of this parapet trim bracket. This lower part of the parapet trim is positioned to overlap with the lower part of the parapet frame in the building height direction when viewed from the thickness direction of the exterior wall material, and has a lower extension that extends from the parapet frame side to the outside.

[0009] On the other hand, at the upper part of the lower section of the parapet trim in the building height direction, the upper section of the parapet trim is attached to the lower part of the parapet frame in the building height direction. This upper section of the parapet trim extends from the parapet frame side to the outside and has an upper extension whose tip is locked to the tip of the lower extension. In this way, the lower section and the upper section of the parapet trim can cover the lower part of the parapet in the height direction, and the lower section and the upper section of the parapet trim function as a trim section of the parapet.

[0010] Incidentally, the upper extension of the top of the parapet trim extends from the parapet frame side to the outside side, and the tip of this extension hangs down in the direction of the building height, which may make it difficult to secure this tip to the tip of the lower extension at the bottom of the parapet trim.

[0011] In this embodiment, a support frame is provided, which comprises a connecting piece and an extending piece. The connecting piece is joined to the parapet frame, and the extending piece extends from the connecting piece toward the outside and supports the upper extending piece from below in the building height direction.

[0012] Therefore, in this embodiment, the support frame prevents the tip portion of the upper extension of the upper part of the parapet trim from sagging downward in the building height direction, thereby enabling the upper and lower parts of the parapet trim to be stably supported against the parapet.

[0013] The second embodiment of the building parapet trim structure further comprises a sealing member provided on the lower surface of the tip of the extended piece, in addition to the first embodiment of the building parapet trim structure, wherein the sealing member is pressed against the locking point between the lower extended portion and the upper extended portion.

[0014] In the second embodiment of the building parapet trim structure, a sealing member is provided on the lower surface of the tip of the extension portion of the support frame, and this sealing member is pressed against the locking point between the lower extension portion of the lower part of the parapet trim and the upper extension portion of the upper part of the parapet trim. Therefore, in this embodiment, it is possible to suppress water sprayed onto the locking point between the lower extension portion and the upper extension portion from penetrating between the lower extension portion and the upper extension portion.

[0015] The third embodiment of the building parapet trim structure is a building parapet trim structure according to the first or second embodiment, wherein the lower part of the parapet trim is arranged in a plurality in the width direction of the exterior wall material, and the boundary between the lower parts of the parapet trim is closed from the parapet trim bracket side, and the upper part in the building height direction is adhered to the extended piece, further comprising a water-stopping sheet.

[0016] In the parapet partition structure of the building according to the third aspect, the lower part of the parapet partition is arranged in a plurality of rows in the width direction of the outer wall material. And the boundary part between the lower parts of the parapet partitions is blocked from the side of the parapet partition bracket by a water stop sheet, and the upper part of the water stop sheet in the building height direction is adhered to the extending piece part of the support frame.

[0017] Therefore, in this aspect, it is possible to suppress the intrusion of water from the outdoor side to the indoor side at the boundary part between the lower parts of the parapet partitions.

Advantages of the Invention

[0018] As described above, the parapet partition structure of the building according to the invention of the present application has an excellent effect of being able to support the partition part of the parapet wall in a stable state.

The support piece portion 44B and the support piece portion 46B support the soffit components (not shown). A lower part of the parapet trim 50 is attached to the outdoor side "outer surface portion 42B1" of the side wall portion 42B of the main plate 42.

[0030] Returning to Figure 2, the lower part 50 of the parapet wall trim extends in the longitudinal direction and comprises a main component 52 that constitutes its main part, a lower component 54 that constitutes its lower part in the building height direction, and a decorative member 56.

[0031] The main component 52 is composed of a main wall portion 52A, a lower extension portion 52B, an upper mounting portion 52C, and a lower mounting portion 52D, which constitute its main part. Specifically, the main wall portion 52A has its plate thickness direction aligned with the beam span direction, and its length in the building height direction is set so that, when viewed from the beam span direction, the main wall portion 52A overlaps with the lower part of the parapet frame 26 in the building height direction and the parapet trim bracket 40.

[0032] The lower extension 52B extends outward from the upper part of the main wall 52A in the building height direction, and is positioned to overlap with the lower part of the parapet frame 26 in the building height direction when viewed from the beam direction. A locking portion 52B1 is provided at the outdoor end of the lower extension 52B, and the "parapet trim upper part 64", which will be described later, is locked to this locking portion 52B1.

[0033] The upper mounting portion 52C is provided in the portion of the main wall portion 52A that overlaps with the upper part of the parapet trim bracket 40 in the building height direction when viewed from the beam-to-beam direction. The upper mounting portion 52C is composed of a beam-to-beam extension portion 52C1 that extends inward from the main wall portion 52A, and a height-direction extension portion 52C2 that extends downward in the building height direction from the indoor-side periphery of the beam-to-beam extension portion 52C1. The height-direction extension portion 52C2 is fixed to the parapet trim bracket 40 by tightening a self-drilling screw 58 to the height-direction extension portion 52C2 from the indoor side of the side wall portion 42B of the parapet trim bracket 40.

[0034] The lower mounting portion 52D extends from the main wall portion 52A towards the interior and downward in the building height direction, below the upper mounting portion 52C in the building height direction, and the lower component member 54 is secured to the lower mounting portion 52D via a fastener 60.

[0035] The lower component 54 extends in the longitudinal direction and includes a rear wall portion 54A, a mounting wall portion 54B, a lower wall portion 54C, a rising portion 54D, and an extended piece portion 54E. Specifically, the rear wall portion 54A constitutes the indoor side portion of the lower component 54, with its plate thickness direction being the beam-to-beam direction, and its upper portion in the building height direction being positioned along the lower portion in the building height direction of the outer surface portion 42B1 of the parapet trim bracket 40. The rear wall portion 54A is fixed to the parapet trim bracket 40 by tightening self-drilling screws 62 from the indoor side of the side wall portion 42B of the parapet trim bracket 40 to the rear wall portion 54A.

[0036] The mounting wall portion 54B extends from the upper peripheral edge of the rear wall portion 54A in the building height direction, upward in the building height direction and outward, and is positioned along the lower mounting portion 52D on the lower side in the building height direction of the lower mounting portion 52D, and is attached to the lower mounting portion 52D with fasteners 60.

[0037] The lower wall portion 54C constitutes the lower part of the lower component member 54 in the building height direction, extends from the rear wall portion 54A toward the outside, and the position of the peripheral edge on the outside in the beam direction coincides with the position of the main wall portion 52A.

[0038] The rising portion 54D extends upward in the building height direction from the outdoor peripheral edge of the lower wall portion 54C, and a locking portion 54D1 provided at the upper end in the building height direction is locked to a locking portion 52E provided on the indoor side of the main wall portion 52A.

[0039] The extended piece 54E extends outwards and downwards in the building height direction from a point in the rising section 54D that overlaps with the lower end of the main wall section 52A in the building height direction when viewed from the beam span direction. The decorative member 56 is attached to the tip 54E1 of the extended piece 54E and the lower part of the rising section 54D in the building height direction. The upper part 64 of the parapet trim is positioned above the lower part 50 of the parapet trim configured as described above in the building height direction.

[0040] The upper part 64 of the parapet trim extends in the longitudinal direction and is composed of a mounting piece 64A and an "upper extension 64B". Specifically, the mounting piece 64A has its plate thickness direction in the direction of the beam span and is positioned directly below the exterior wall material 32. The mounting piece 64A is fixed to the parapet frame 26 by tightening a self-drilling screw 66 from the outside.

[0041] The upper extension portion 64B extends outward from the lower peripheral edge of the mounting piece portion 64A in the building height direction, and a locking portion 64B1 provided at the outer end is locked to the locking portion 52B1 of the lower extension portion 52B.

[0044] Furthermore, a "seal member 70" made of EPDM (ethylene propylene diene rubber) is provided on the lower surface of the outdoor end of the extended piece 68B, extending in the longitudinal direction. This seal member 70 is pressed against the locking point between the lower extended portion 52B and the upper extended portion 64B from above in the building height direction.

[0045] Furthermore, in this embodiment, as shown in Figure 4, the corner wall portion 24 also has a "lower part of the lower

[0046] As shown in Figure 5, the waterproofing sheet 74 is positioned along the main wall portion 52A and lower mounting portion 52D of the main component 52, and the rear wall portion 54A of the lower component 54, at the lower part 50 of the parapet trim. It is also positioned along the main wall portion 76A and lower mounting portion 76B of the main component 76, and the rear wall portion 78A of the lower component 78, at the lower part 72 of the parapet trim. Furthermore, the upper portion of the waterproofing sheet 74 in the height direction is bonded to the extended piece 68B of the support frame 68.

[0047] In this embodiment, the balcony 16 is shipped from the factory with the upper part 64 of the parapet trim and the support frame 68 attached to the parapet frame 26, and the subassembly including the parapet trim bracket 40 and the lower part 50 of the parapet trim is attached to the parapet trim bracket 40 on-site.

[0048] <Operation and Effects of This Embodiment> Next, the operation and effects of this embodiment will be described.

[0049] In this embodiment, as shown in Figure 2, a parapet frame 26, which constitutes a part of the structure of the balcony parapet 20, extends in the building height direction, and an exterior wall material 32 is attached to this parapet frame 26 to form a part of the wall surface of the balcony parapet 20. A parapet trim bracket 40 is attached to the lower side of the parapet frame 26 in the building height direction.

[0050] The lower part of the parapet trim bracket 40 is fitted with the lower part of the parapet trim 50, which is positioned so as to overlap with the lower part of the parapet frame 26 in the building height direction when viewed from the thickness direction of the exterior wall material 32, and has a lower extension 52B that extends from the parapet frame 26 side to the outside.

[0051] On the other hand, on the upper side of the lower part 50 of the parapet trim in the building height direction, the upper part 64 of the parapet trim is attached to the lower part of the parapet frame 26 in the building height direction. This upper part 64 of the parapet trim extends from the parapet frame 26 side to the outside and has an upper extension 64B at its tip that is locked to the tip of the lower extension 52B. In this way, in this embodiment, the lower part 50 of the parapet trim and the upper part 64 of the parapet trim can cover the lower part of the balcony parapet 20 in the height direction, and the lower part 50 of the parapet trim and the upper part 64 of the parapet trim function as a trim for the balcony parapet 20.

[0052] Incidentally, the upper extension portion 64B of the upper part 64 of the parapet trim extends from the parapet frame 26 side to the outside side, and the tip portion hangs down in the direction of the building height, which may make it difficult to lock this tip portion with the tip portion of the lower extension portion 52B of the lower part 50 of the parapet trim.

[0053] In this embodiment, a support frame 68 is provided, which comprises a connecting piece 68A and an extending piece 68B. The connecting piece 68A is joined to the parapet frame 26, and the extending piece 68B extends from the connecting piece 68A toward the outside and supports the upper extending piece 64B from below in the building height direction.

[0054] Therefore, in this embodiment, the support frame 68 prevents the tip portion of the upper extension 64B of the upper part of the parapet trim 64 from sagging downward in the building height direction, and consequently, the upper part 64 and lower part 50 of the parapet trim can be stably supported with respect to the balcony parapet 20.

[0055] Furthermore, in this embodiment, a sealing member 70 is provided on the lower surface of the tip of the extension portion 68B of the support frame 68, and this sealing member 70 is pressed against the locking point between the lower extension portion 52B of the lower part of the parapet trim 50 and the upper extension portion 64B of the upper part of the parapet trim 64. Therefore, in this embodiment, water sprayed onto the locking point between the lower extension portion 52B and the upper extension portion 64B can be prevented from entering between the lower extension portion 52B and the upper extension portion 64B.

[0056] Furthermore, in this embodiment, the lower part 50 of the parapet trim and the lower part 72 of the parapet trim are arranged in a continuous line in the width direction of the exterior wall material 32. The boundary between the lower part 50 of the parapet trim and the lower part 72 of the parapet trim is sealed from the parapet trim bracket 40 side with a waterproofing sheet 74, and the upper part of this waterproofing sheet 74 in the building height direction is bonded to the extended piece 68B of the support frame 68.

[0057] Therefore, in this embodiment, it is possible to suppress the intrusion of water from the outdoor side to the indoor side at the boundary between the lower part of the parapet trim 50 and the lower part of the parapet trim 72.

[0058] As described above, in the building parapet wall trim structure according to this embodiment, the trim portion of the balcony parapet wall 20 can be supported in a stable state.

[0059] In this embodiment, the building's parapet trim structure was equipped with a sealing member 70. However, depending on the manufacturing precision of the lower part 50 of the parapet trim, the upper part 64 of the parapet trim, and the support frame 68, the sealing member 70 may not be provided.
