Description

[Technical Field]

[0001] The present disclosure relates to buildings. [Background technology]

[0002] There is known a technique for installing a sash on a foundation. For example, in Patent Document 1, a sash is installed on the foundation via a ventilation material and a base that are placed on the foundation. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-152501 Summary of the Invention [Problem to be solved by the invention]

[0004] When a sash is installed on a foundation without a base, multiple spacers are placed at intervals on the foundation, and the sash is attached to the spacers. In this type of installation structure, gaps are provided between the foundation and the sash between the spacers. To prevent rainwater from entering through the gaps, the gaps are filled with mortar. Thus, in conventional structures, the gaps between the sash and the foundation must be filled with mortar. This mortar filling process takes time, which means that installing the sash takes time. [Means for solving the problem]

[0005] (1) A building that solves the above problem is a building that includes a foundation, an exterior wall structural portion, an opening provided in the exterior wall structural portion, a sash provided in the opening, a spacer provided between the foundation and the sash and supporting the sash, and a cover that covers the gap between the foundation and the sash, wherein the spacer has a spacer main body and a spacer mounting portion provided on the spacer main body and to which the cover is attached.

[0006] With this configuration, the gap between the foundation and the sash of the building can be covered with the cover, eliminating the need to fill the gap between the sash and the foundation with mortar, which simplifies the construction work required to seal the gap between the foundation and the sash of the building.

[0007] (2) In the building of (1) above, the spacer body has a bottom plate portion attached to the foundation, a vertical plate portion extending upward from the bottom plate portion, and an upper plate portion provided on the vertical plate portion, and the spacer mounting portion of the spacer extends downward from the end of the upper plate portion, and an insertion portion into which the cover is inserted is provided between the spacer mounting portion and the vertical plate portion.

[0008] According to this configuration, the spacer is provided with an insertion portion into which the cover is inserted, so that the cover can be attached to the spacer along the insertion portion, making it easy to attach the cover to the spacer.

[0009] (3) In the building of (1) or (2) above, the sash has a sash mounting portion attached to the spacer mounting portion, the sash mounting portion is arranged so as to contact the outer surface of the spacer mounting portion, and the cover is arranged so as to contact the inner surface of the spacer mounting portion. With this configuration, the sash can be arranged outermost among the sash, spacer, and cover.

[0010] When a cover is placed between the sash mounting portion and the spacer mounting portion, the bond between the sash mounting portion and the spacer mounting portion may be weakened, resulting in a decrease in fire resistance compared to when there is no cover. In this regard, with the above-mentioned configuration, the cover can be attached to the spacer while the sash mounting portion and the spacer mounting portion are in contact with each other. Therefore, even when a cover is provided, a decrease in fire resistance can be suppressed.

[0011] (4) In the building described in (3) above, the sash and the cover are attached to the spacer by fastening members that penetrate the sash mounting portion, the spacer mounting portion, and the cover so that the heads of the fastening members contact the outer surfaces of the sash mounting portions. This configuration ensures that the fastening members have a sufficient distance from the heads of the fastening members to the sash, allowing the fastening members to properly fasten the sash.

[0012] (5) In the building of any one of (1) to (4) above, the sash is provided so as to protrude outward from the outer surface of the foundation. According to this configuration, the building can increase the floor area inside the building by using the sash 10.

[0013] (6) In the building of any one of (1) to (5) above, the cover has a cover front portion that covers the gap between the sash and the foundation, and a bottom portion that extends from a lower end of the cover front portion toward the foundation. With this configuration, the cover can prevent moisture and the like from entering between the sash and the foundation from the outside by the cover front portion and the bottom portion.

[0014] (7) In the building of (6) above, the lower end of the cover front portion is located below the upper surface of the foundation. With this configuration, since the lower end of the cover front portion is below the upper surface of the foundation, moisture and the like are less likely to penetrate between the sash and the foundation from the outside.

[0015] (8) In the building of (7) above, the cover further has a side portion provided at an end of the front portion of the cover in the longitudinal direction of the cover, and the side portion is arranged at a distance from the bottom portion of the cover. With this configuration, since the side portion is arranged at a distance from the bottom portion, moisture and the like are less likely to accumulate inside the cover. [Effects of the Invention]

[0016] According to the building disclosed herein, construction work to seal the gap between the foundation and the sash can be simplified. [Brief explanation of the drawings]

[0049] The fastening member 8 passes through the first sash hole 13B, the mounting hole 27, and the cover mounting hole 35 in this order so that the head 8A of the fastening member 8 contacts the outer surface 13A of the sash mounting portion 13. By tightening the fastening member 8, the sash 10 and the cover 30 are attached to the spacer 20 in the order of sash 10, spacer 20, and cover 30.

[0050] <Operation of this embodiment> The operation of this embodiment will be described. The building 1 includes a foundation 2, an exterior wall structural portion 4A, an opening 5, a sash 10, a cover 30, and a spacer 20 to which the cover 30 is attached. As a result, the cover 30 can be attached to the spacer 20, so that the gap A1 between the sash 10 and the foundation 2 can be easily covered.

[0051] <Effects of this embodiment> The effects of this embodiment will be described. (1) The building 1 includes a foundation 2, an exterior wall structural portion 4A, an opening 5 provided in the exterior wall structural portion 4A, a sash 10 provided in the opening 5, a spacer 20 provided between the foundation 2 and the sash 10 and supporting the sash 10, and a cover 30 covering the gap A1 between the foundation 2 and the sash 10. The spacer 20 includes a spacer main body 21 and a spacer mounting portion 22 provided on the spacer main body 21 and to which the cover 30 is attached.

[0052] According to this configuration, the building 1 can use the cover 30 to cover the gap A1 between the foundation 2 and the sash 10, eliminating the need to fill the gap A1 between the sash 10 and the foundation 2 with mortar. This simplifies the construction work required to close the gap A1 between the foundation 2 and the sash 10 of the building 1.

[0053] (2) The spacer body 21 has a bottom plate portion 23 attached to the foundation 2, a vertical plate portion 24 extending upward from the bottom plate portion 23, and an upper plate portion 25 provided on the vertical plate portion 24. The spacer mounting portion 22 of the spacer 20 extends downward from an end portion 25A of the upper plate portion 25. An insertion portion 26 into which the cover 30 is inserted is provided between the spacer mounting portion 22 and the vertical plate portion 24.

[0054] According to this configuration, the spacer 20 is provided with the insertion portion 26 into which the cover 30 is inserted, so that the cover 30 can be attached to the spacer 20 along the insertion portion 26. This makes it easy to attach the cover 30 to the spacer 20.

[0055] (3) The sash 10 has a sash mounting portion 13 that is attached to the spacer mounting portion 22. The sash mounting portion 13 is arranged so as to contact the outer surface 22A of the spacer mounting portion 22. The cover 30 is arranged so as to contact the inner surface 22B of the spacer mounting portion 22. With this configuration, the sash 10 can be arranged outermost among the sash 10, spacer 20, and cover 30.

[0056] When the cover 30 is disposed between the sash mounting portion 13 and the spacer mounting portion 22, the bond between the sash mounting portion 13 and the spacer mounting portion 22 may be weakened, resulting in a decrease in fire resistance compared to when the cover 30 is not present. In this regard, with the above-described configuration, the cover 30 can be attached to the spacer 20 while the sash mounting portion 13 and the spacer mounting portion 22 are in contact with each other. Therefore, even when the cover 30 is provided, a decrease in fire resistance can be suppressed.

[0057] (4) The sash 10 and the cover 30 are attached to the spacer 20 by fastening members 8. The fastening members 8 penetrate the sash mounting portion 13, the spacer mounting portion 22, and the cover 30 so that the heads 8A of the fastening members 8 contact the outer surfaces 13A of the sash mounting portions 13. This configuration ensures a sufficient distance between the heads 8A of the fastening members 8 and the sash 10, allowing the fastening members 8 to suitably fasten the sash 10.

[0058] (5) The sash 10 is provided so as to protrude outward from the outer surface 2E of the foundation 2. According to this configuration, the sash 10 allows the building 1 to have a larger indoor floor area.

[0059] (6) In a side view, the cover 30 has a cover front portion 31 that covers the gap A1 between the sash 10 and the foundation 2, and a bottom portion 32 that extends from a lower end 31A of the cover front portion 31 toward the foundation 2. With this configuration, the cover 30 can prevent moisture and the like from entering between the sash 10 and the foundation 2 from the outside by means of the cover front portion 31 and the bottom portion 32.

[0060] (7) In the cover front portion 31, the lower end 31A of the cover front portion 31 is located below the upper surface 2F of the foundation 2. According to this configuration, since the lower end 31A of the cover front portion 31 is located below the upper surface 2F of the foundation 2, moisture and the like are less likely to enter between the sash 10 and the foundation 2 from the outside.

[0061] (8) The cover 30 further has a side surface portion 34 provided at an end 31B of the cover front surface portion 31 in the longitudinal direction of the cover 30. The side surface portion 34 is disposed at a distance A2 from the bottom surface portion 32 of the cover 30. According to this configuration, since the side surface portion 34 is disposed at a distance A2 from the bottom surface portion 32, moisture and the like are less likely to accumulate inside the cover 30.

[0062] <Example of change> The above embodiment is an example of a form that the building 1 can take, and is not intended to limit the form. The building 1 can take a form different from the form exemplified in the above embodiment. Examples of such a form include a form in which part of the configuration of the embodiment is replaced, modified, or omitted, or a form in which a new configuration is added to the embodiment. Modified examples of the embodiment are shown below.

[0063] As shown in Fig. 6, an external structure 40 may be provided outside the sash 10. The external structure 40 is a wood deck or grating.

[0064] In the spacer 20, the vertical plate portion 24 may be provided only at one end 23B in the short direction of the bottom plate portion 23. In this case, the spacer 20 has one spacer mounting portion 22. The spacer 20 is attached to the sash 10 and the cover 30 by the one spacer mounting portion 22.

[0065] A nut having an internal thread that engages with the external thread of the fastening member 8 may be welded to the foundation 2 side of the cover mounting hole 35. In this case, the internal threads provided in the mounting hole 27, the first sash hole 13B, and the cover mounting hole 35 may be omitted.

[0066] The side surface portion 34 may be continuous with the end portion 32A of the bottom surface portion 32 of the cover 30 and extend toward the sash 10. In this case, the side surface portion 34 is disposed with a gap between it and the end portion 31B of the cover front surface portion 31.

[0067] The sealing portion 33 may be omitted.
