Description

  The present invention relates to an eave structure of a building.

  In a building such as a house, when a shutter device is provided for a window portion formed on the outer wall, the shutter case of the shutter device is often attached to the outer wall surface above the window portion. For example, in a building where an eaves ceiling is provided above the opening, there is a configuration in which a shutter case is disposed between the window and the eaves ceiling (for example, Patent Document 1). In this configuration, the shutter case is disposed below the eaves ceiling.

JP 2002-106273 A

  However, in the configuration in which the shutter case is arranged below the eaves ceiling, when the height dimension of the shutter case is larger than the separation distance between the eaves ceiling and the window part, the shutter case closes the upper part of the window part. turn into. Further, when the shutter case is disposed between the eaves ceiling and the window part, the vertical dimension of the window part is limited by the shutter case, not the eaves ceiling.

  Therefore, it is conceivable to embed the shutter case in the eaves ceiling from below. Thereby, it can avoid that the shutter case will be in the state which block | closed the window part, and that the magnitude | size of the vertical dimension of a window part is controlled by a shutter case.

  Here, in the eaves top plate forming the ceiling surface of the eaves ceiling, the end on the outer wall side is generally fixed to the outer wall. However, in the portion where the shutter case is embedded in the eaves ceiling, the shutter case exists between the eaves top plate and the outer wall, and the end of the eaves top plate on the shutter case side is fixed to the outer wall. It becomes difficult. In addition, if the shutter case does not have enough strength to hold the eaves top plate, the shutter case may be damaged or deformed. It cannot be fixed.

  In any case, the shutter case side end of the eaves top plate cannot be suitably fixed, and there is a concern that the eaves top plate may be in an unstable mounting state. This concern occurs not only in the shutter case but also when other building facilities are embedded in the eaves ceiling from below.

  The present invention has been made in view of the above circumstances, and provides a building eaves-top structure that can make the support state of the eaves top plate appropriate even when building facilities are embedded in the eaves ceiling. Is the main purpose.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary.

  The eaves-top structure of the building of the first invention is applied to a building in which building facilities are attached to the outer wall surface of the building, and the building facilities are embedded from below in an eaves ceiling provided on the eaves portion of the roof, An eaves top plate forming a ceiling surface on the eaves ceiling, and eaves material provided at a predetermined position of the eaves part, and an end surface of the eaves top plate on the building equipment side is on a side surface of the building equipment The eaves material is attached with a support bracket that has an extending portion extending toward the building equipment and supports an end of the eaves top plate on the building equipment side. It is characterized by.

  According to the first invention, in the configuration in which the building equipment is embedded in the eaves ceiling, since the extending portion of the support bracket extends toward the building equipment, the eaves material is arranged at a position separated from the building equipment. Even if it is, the edge part by the side of building equipment in an eaves top board can be supported by the front-end | tip part of an extension part. Thereby, even if it does not fix an eaves top board to building facilities, it can eliminate that the attachment state of an eaves top board becomes unstable. In addition, although it is conceivable to install the eave material at a position that can support the end of the eaves top plate on the building equipment side, according to the present invention, the position of the eave material is matched to the shape and size of the building equipment. Even if it does not change, the edge part by the side of the building equipment in an eaves top board can be supported suitably. Therefore, it is possible to reduce the burden of design change and the burden of constructing the eaves ceiling. As described above, even when the building equipment is embedded in the eaves ceiling, the support state of the eaves top plate can be made appropriate.

  In a second invention, in the first invention, the eaves material is a beam material disposed above the eaves top plate, and a plurality of the support brackets are provided along a longitudinal direction of the beam material. Yes.

  When the eaves top plate is attached to the beam material, the beam material needs to support not only the end of the eaves top plate on the building equipment side but also other parts of the eaves top plate. For this reason, if the position of the beam material is changed according to the size and shape of the building equipment, the end of the eaves top plate on the building equipment side can be favorably supported, but the other part of the eaves top plate is appropriate. There is a concern that it cannot be supported in a difficult state.

  On the other hand, according to the second invention, the end of the eaves top plate on the building equipment side can be suitably supported by the support bracket without changing the position of the beam material. The whole can be suitably supported.

  In addition, it is preferable that the intermediate bracket which supports the part which is not the edge part by the side of the building equipment in an eaves top plate is attached to the same beam material as a support bracket. In this case, for the beam material to which the intermediate bracket is attached, the entire eaves top plate can be easily replaced by replacing the intermediate bracket with a support bracket or adding a support bracket according to the size and shape of the building equipment. It can support suitably.

  In a third invention, in the second invention, above the eaves top plate, an eaves top frame in which a plurality of the beam members extending in the intersecting direction are connected to each other is provided, and the support bracket is A plurality of the plurality of beam members are provided along a longitudinal direction of at least one beam member.

  According to the third invention, when the eaves ceiling construction is industrialized by unitizing the eaves ceiling frame, it is difficult to change only the position of one beam member at the construction site. Moreover, even if the position of one beam material is changed, the number of work steps at the construction site increases. On the other hand, in the structure which supports the edge part by the side of the building equipment in an eaves top board, the increase in the work man-hour at a construction site can be suppressed by using a support bracket instead of changing the position of a beam material.

  In a fourth invention, in the third invention, the building has an upper floor part installed under the roof, and a lower floor part installed below the upper floor part, The upper floor portion has a loggia space as an outdoor space provided between the eave ceiling and the indoor space of the lower floor portion, and the eave portion is directed upward from the floor portion of the loggia space. The outdoor pillar is extended from below, and the outdoor pillar and the eaves frame are connected to form a loggia frame.

  According to the fourth aspect of the present invention, since the construction of the loggia space is being industrialized by using the unitized logia frame, it becomes difficult to change only the position of one beam material at the building site. Yes. Moreover, even if it can be changed, the number of work steps at the construction site increases. In particular, since the outdoor column is integrated with the beam material, it is difficult to change the position of the beam material even at the design stage. On the other hand, in the structure that supports the end of the building equipment side of the eaves top plate, it is possible to suppress an increase in work man-hours at the construction site by using a support bracket instead of changing the position of the beam material. The troublesome design change can be eliminated.

  In addition, when the depth of the loggia space is wide, there is a concern that the supporting strength is insufficient only by the cantilever support of the eave portion by the outer wall due to the large protruding dimension of the eave portion from the outer wall. Therefore, it is preferable that a portion of the eave portion closer to the eaves is supported by an outdoor pillar.

  According to a fifth invention, in any one of the first to fourth inventions, the support bracket has an upright portion extending upward from the extension portion, and the upright portion is provided in the support bracket. Is attached to the side of the eaves.

  According to 5th invention, the height position of a support bracket can be adjusted with the easy operation | work of changing the position of the standing part with respect to eaves material to an up-down direction. For this reason, even if the height position of the eave material is deviated from the height position of the eaves top plate, the deviation can be eliminated by adjusting the height position of the support bracket. Thereby, the height position of an eaves top board can be set appropriately about an up-down direction.

  In a sixth invention, in any one of the first to fifth inventions, an intermediate bracket that supports the eaves top plate is attached to the eaves material at a position farther from the building equipment than the support bracket. The eaves top plate is attached to both the support bracket and the intermediate bracket via a base material.

  According to the sixth invention, since the base material is used for both the support bracket and the intermediate bracket, the eaves top plate is composed of the end of the eaves top plate on the building equipment side and the other parts. There is no need to use different base materials for fixing. Thereby, the cost burden and work burden can be reduced for the eaves ceiling construction.

  According to a seventh aspect, in the sixth aspect, the base material is provided between the extension portion and the eaves top plate, and is attached to the lower surface of the extension portion.

  According to the seventh invention, the position of the base material can be adjusted in the direction approaching (moving away from) the building facility by an easy operation of shifting the position of the base material along the lower surface of the extending portion. . For this reason, even if the extension dimension of the extension part of the support bracket is deviated with respect to the separation distance between the eaves material and the building equipment, the deviation can be eliminated by adjusting the position of the base material with respect to the extension part 75. Thereby, the alignment of the base material with respect to the building facility can be easily performed in the direction approaching the building facility.

  In an eighth invention according to the sixth or seventh invention, the support bracket has a downward projecting portion projecting downward from a tip end of the extending portion, and the base material comprises the extending member. It is provided on the building equipment side with respect to the extending part in the extending direction of the protruding part, and is attached to the surface on the building equipment side in the downward projecting part.

  According to the eighth aspect, the height position of the base material can be adjusted by an easy operation of shifting the position of the base material along the side surface of the downward projecting portion. For this reason, even if the height position of the support bracket is deviated from the installation height of the eaves top plate, the deviation can be eliminated by adjusting the height position of the base material. Thereby, the attachment position of the eaves top board can be appropriately set about the up-down direction.

  According to a ninth invention, in any one of the first to eighth inventions, an outer wall opening is provided in the outer wall from which the eaves portion projects, and the outer wall opening is provided with respect to the outer wall opening. A shutter curtain having a shutter curtain that moves up and down on the outdoor side and a shutter case that houses the shutter curtain is provided, and the shutter case is embedded in the ceiling of the eave as the building equipment from below .

  According to the ninth aspect, in the configuration in which the shutter case is embedded in the eaves ceiling, the end of the eaves top plate on the shutter case side can be suitably supported.

  The eaves ceiling frame 62 has outdoor large beams 65 a and 65 b connected to the outdoor pillar 61, and intermediate beams 66 a and 66 b connected to the outdoor large beam 65. The outdoor large beams 65a and 65b and the intermediate beams 66a and 66b are both frame materials formed of grooved steel having a U-shaped cross section. The outdoor large beams 65a and 65b are in a state of being bridged between the outdoor column 61 and the outer wall 18, and are fixed to the outdoor column 61 and the outer wall 18 (ceiling large beam 41 or indoor column) by bolts, welding, or the like. ing. Of the outdoor large beams 65a and 65b, the long outdoor large beam 65a extending along the longitudinal direction of the loggia space 17 extends in parallel with the long side of the outdoor floor portion 17a, and extends along the short direction of the loggia space 17. The extended short outdoor large beam 65b extends in parallel with the short side of the outdoor floor portion 17a.

  The intermediate beams 66 a and 66 b are connected to the outdoor large beam 65. Of the intermediate beams 66a and 66b, the longitudinal intermediate beam 66a extending along the longitudinal direction of the loggia space 17 is disposed between the outer wall 18 and the longitudinal outdoor large beam 65a, and extends in parallel with the longitudinal outdoor large beam 65a. Yes. The short intermediate beam 66b extending along the short direction of the logistic space 17 is disposed between the outer wall 18 and the short outdoor large beam 65b, and extends in parallel with the short outdoor large beam 65b. In the long outdoor large beam 65a and the long intermediate beam 66a, the groove opening sides face each other, and in the short outdoor large beam 65b and the short intermediate beam 66b, the groove opening sides face each other.

  The short intermediate beam 66b is bridged between the long outdoor large beam 65a and the outer wall 18, and the long outdoor large beam 65a and the outer wall 18 (ceiling large beam 41 and indoor pillar) are respectively bolted or welded. It is connected. The long intermediate beam 66a is spanned between the short outdoor large beam 65b and the short intermediate beam 66b, and is connected to each of the short outdoor large beam 65b and the short intermediate beam 66b by bolts, welding, or the like. Has been.

  Further, the eaves frame 62 has an intermediate beam 67 that connects the long outdoor large beam 65a and the long intermediate beam 66a. The intermediate beam 67 is made of a frame material formed of groove-shaped steel having a U-shaped cross section, like the outdoor large beams 65a and 65b. Bolts, welding, and the like are respectively attached to the long outdoor large beam 65a and the long intermediate beam 66a. Connected by.

  In the present embodiment, a loggia frame 68 is formed by unitizing the outdoor pillar 61 and the eaves frame 62. Like the building unit, the loggia frame 68 is manufactured at the factory, and then transported from the factory to the building site by a transportation means such as a truck. Then, after a plurality of building units are installed at the building site, they are fixed to the pillars and ceiling beams of the building units in the loggia space 17. For this reason, about the installation work of the loggia frame 68, the work burden in a construction site can be reduced.

  In the logistic space 17, the shutter case 22 is disposed between the longitudinal intermediate beam 66 a and the outer wall 18. Here, in the portion where the shutter case 22 does not exist between the eaves top plate 33 and the outer wall 18, the end of the eaves top plate 33 can be fixed to the outer wall 18. In the portion where the shutter case 22 exists between the outer wall 18 and the outer wall 18, the end of the eaves top plate 33 cannot be fixed to the outer wall 18. Moreover, when the longitudinal intermediate beam 66a is separated from the shutter case 22, the end of the eaves top plate 33 on the shutter case 22 side cannot be fixed to the longitudinal intermediate beam 66a. In addition, fixing the eaves top plate 33 to the shutter case 22 is not preferable because the strength of the shutter case 22 is not the strength assumed to support the eaves top plate 33.

  Therefore, a method of changing the position of the longitudinal intermediate beam 66a to the shutter case 22 side and fixing the end of the eaves top plate 33 on the shutter case 22 side to the longitudinal intermediate beam 66a can be considered. However, even in an industrialized building using a building unit, the shape and size of the shutter case 22 are assumed to be different for each building 10 according to the user's request and purpose of use. In the building 10 manufactured in the factory, changing the position of the longitudinal intermediate beam 66a in accordance with the shutter case 22 leads to an increase in cost burden and a reduction in work efficiency.

  On the other hand, in this embodiment, the edge part by the side of the shutter case 22 in the eaves top board 33 is supported from the longitudinal intermediate beam 66a side. Thereby, even if it does not change the position of the longitudinal intermediate beam 66a, it can suppress that the attachment state of the eaves top plate 33 becomes unstable around the shutter case 22.

  As shown in FIG. 2, the eaves top base 63 includes brackets 71 and 72 attached to the eaves top frame 62 and a base material 73 attached to the brackets 71 and 72.

The reinforcing portion 77 is a plate portion extending in a direction orthogonal to the extending portion 75 and the standing portion 76, and extends into the corners of the extending portion 75 and the standing portion 76, and the extending portion 75 and The portions near the free ends of the standing portions 76 are connected. The reinforcing portion 77 is fixed to each of the extending portion 75 and the standing portion 76 by welding or the like.

  The 1st bracket 71 is being fixed with the volt | bolt 78 as a fixing tool with respect to the side surface on the opposite side to the groove part open side in the surrounding surface of the longitudinal intermediate beam 66a. The longitudinal intermediate beam 66a has a web 79a and a pair of flanges 79b opposed to each other with the web 79a interposed therebetween. The outer surface of the upright portion 76 of the first bracket 71 (with respect to the outer surface of the web 79a) The surface opposite to the extending portion 75) is overlapped, and a bolt 78 penetrating through the standing portion 76 in this state is screwed to the web 79a side.

  The extension portion 75 extends along the base material 73, and the base material 73 is fixed to the extension portion 75 with screws or the like in a state where the upper surface thereof overlaps the lower surface of the extension portion 75. The base material 73 is disposed below the distal end portion of the extending portion 75. That is, as shown in FIG. 2, it is arranged at a position spaced from the longitudinal intermediate beam 66a toward the shutter case 22 side. In this case, the end of the eaves top plate 33 on the shutter case 22 side is fixed to the base material 73 supported by the first bracket 71. Further, the base material 73 is sandwiched between the extending portion 75 and the eaves top plate 33.

  On the other hand, the second bracket 72 is disposed at a position farther from the shutter case 22 than the first bracket 71, and supports the eaves top plate 33 at that position. The second bracket 72 is attached to each of the outdoor large beams 65a and 65b, the intermediate beams 66a and 66b, and the intermediate small beam 67. Each of the second brackets 72 extends downward from a beam material such as the long outdoor large beam 65a, and the base material 73 is fixed to a side surface of the second bracket 72 by a fixing tool such as a screw. The second bracket 72 corresponds to an intermediate bracket.

  Incidentally, in the longitudinal intermediate beam 66a, the first bracket 71 is attached to the portion facing the shutter case 22, and the portion not facing the shutter case 22 (the portion protruding sideward from the shutter case 22). ) Has a second bracket 72 attached thereto. In this case, the longitudinal intermediate beam 66a supports the eaves top plate 33 via the first bracket 71 or the second bracket 72 in all regions where the longitudinal intermediate beam 66a is installed.

  In the eaves top plate 33, a part closer to the eaves side than the loggia space 17 is supported by the roof portion 13. For example, the eaves end of the roof part 13 is provided with a nose cover part, and the end part on the eaves side in the eaves top plate 33 is attached to the nose cover part. In addition, a suspension member 81 for hanging and supporting the foundation material 73 is attached to the roof foundation portion such as the rafter 51 and the main building material 54, and the eaves top plate 33 is the foundation in the region between the loggia space 17 and the eaves edge. It is fixed to the suspension member 81 via a material 73. In this case, from the viewpoint of the structure for supporting the eaves ceiling 32, the roof base portion to which the suspension member 81 is attached is included in the eave material, and the suspension member 81 is included in the eave ceiling.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

Since the extending portion 75 of the first bracket 71 extends toward the shutter case 22, the first bracket attached to the longitudinal intermediate beam 66 a even when the longitudinal intermediate beam 66 a is located away from the shutter case 22. 71, the end of the eaves top plate 33 on the shutter case 22 side can be supported by the tip of the extending portion 75. Thereby, even if the eaves top plate 33 is not fixed to the shutter case 22, it is possible to eliminate the unstable mounting state of the eaves top plate 33.
Although it is conceivable to install the longitudinal intermediate beam 66a at a position where the end of the eaves top plate 33 on the shutter case 22 side can be supported, the first bracket 71 has the extending portion 75. Even if the position of the intermediate beam 66a is not changed in accordance with the shape and size of the shutter case 22, the end of the eaves top plate 33 on the shutter case 22 side can be suitably supported. Therefore, it is possible to reduce the burden of design change and the burden when constructing the eaves ceiling 32.

  As described above, even if the shutter case 22 is embedded in the eaves ceiling 32, the support state of the eaves top plate 33 can be made appropriate.

  Since the longitudinal intermediate beam 66a supports other portions of the eaves top plate 33 on the shutter case 22 side as well as other parts as beam members, the eaves ceiling can be changed without changing the position of the longitudinal intermediate beam 66a. The ability to support the end portion of the plate 33 on the shutter case 22 side by the first bracket 71 is effective in properly supporting the entire eaves top plate 33.

  Here, since both the first bracket 71 and the second bracket 72 are attached to the longitudinal intermediate beam 66a, the longitudinal intermediate beam 66a is provided only for supporting the end of the eaves top plate 33 on the shutter case 22 side. When the position is changed, the position of the second bracket 72 is also changed, and the other part of the eaves top plate 33 cannot be properly supported. For this reason, the attachment of the first bracket 71 to the longitudinal intermediate beam 66a is also effective in supporting the eaves top plate 33 in an appropriate state by the second bracket 72.

  Since the eaves top frame 62 and the loggia frame 68 including the eaves top frame 62 are unitized, it is difficult to change only the position of the longitudinal intermediate beam 66a at the construction site. Even if only the position of the longitudinal intermediate beam 66a is changed, a part or the whole of the logia frame 68 and the eaves frame 62 is disassembled, and the number of work steps at the construction site increases. Accordingly, the fact that the end of the eaves top plate 33 on the shutter case 22 side is supported by the longitudinal intermediate beam 66a via the first bracket 71 also suppresses an increase in the number of work steps at the construction site.

  In particular, when considering changing the position of the longitudinal intermediate beam 66a in the loggia frame 68, the structural strength of the entire loggia frame 68 including the outdoor pillar 61 also changes. The entire configuration will be changed. Therefore, the fact that the end portion on the shutter case 22 side of the eaves top plate 33 is supported by the longitudinal intermediate beam 66a via the first bracket 71 also eliminates the troublesome design change.

  In the first bracket 71, since the plate surface of the upright portion 76 is overlapped with the side surface of the long intermediate beam 66a, the position of the upright portion 76 can be easily changed in the vertical direction along the side surface of the long intermediate beam 66a. The height position of the first bracket 71 can be adjusted by the work. For this reason, even if the height position of the longitudinal intermediate beam 66 a is deviated from the height position of the eaves top plate 33, the deviation can be eliminated by adjusting the height position of the first bracket 71. Thereby, the height position of the eaves top board 33 can be set appropriately about the up-down direction.

  Since the eaves top plate 33 is fixed to the first bracket 71 and the second bracket 72 via the base material 73, a dedicated base material is used for each of the first bracket 71 and the second bracket 72. There is no need to use them properly. Thereby, the cost burden and work burden can be reduced for the construction of the eaves ceiling 32.

  Since the base material 73 is disposed below the extension portion 75 of the first bracket 71, the shutter material 21 can be moved with respect to the shutter curtain 21 by an easy operation of shifting the position of the base material 73 along the lower surface of the extension portion 75. The position of the base material can be adjusted with respect to the approaching direction (the moving away direction). For this reason, even if the extension dimension of the extension part 75 of the first bracket 71 is deviated with respect to the separation distance between the longitudinal intermediate beam 66 a and the shutter case 22, the deviation is applied to the base material 73 with respect to the extension part 75. It can be solved by adjusting the position of Accordingly, the base material 73 can be easily aligned with the shutter case 22 in the direction approaching the shutter case 22.

  Furthermore, since the extension part 75 is plate-shaped, the base material 73 can be shifted in the width direction of the extension part 75 along the lower surface of the extension part 75. Thereby, the alignment of the base material 73 with respect to the shutter case 22 can be easily performed in a direction intersecting with the extending direction of the extending portion 75.

According to this configuration, the eaves top plate 33 can be directly supported by the first bracket 71 without using the base material 73. Further, if the hooking portion 94 extends along the end of the eaves top plate 33, the hooking portion 94 can be used as a parting member.

  In addition, also in the 1st bracket 71 which has the hook part 94, the base material 73 may be attached to the lower side of the extension part 75. FIG.

  (5) In the said embodiment, although the 1st bracket 71 was fixed with respect to the side surface of the longitudinal outdoor large beam 65a, the 1st bracket 71 may be fixed with respect to the upper surface and lower surface of the longitudinal outdoor large beam 65a. . For example, the first bracket 71 is fixed to the long outdoor outdoor beam 65a in a state where the first bracket 71 does not have the standing portion 76 and the upper surface of the extending portion 75 is overlapped with the lower surface of the long outdoor large beam 65a.
