Description

The present invention relates to buildings.

Patent Document 1 describes a hipped roof truss construction method for a building (hipped roof truss structure). In this hipped roof truss construction method, H-shaped steel is used for the slats formed in a flat frame shape, the horizontal timber beams that are placed higher than the slats in the center of the inside surrounded by the slats, and the corner gables that are placed at an angle between the ends of the timber beams and each corner of the slats. H-shaped steel is used for the gables that are placed at an angle with the slat side lowered in the parallel part between the slats and the slats, and channel steel is used for the main frame that is placed across the gables and corner gables. After the slats and timber beams are placed on the building frame, the ends of the timber beams and the upper ends of the corner gables and the corner gables are placed on the building frame. The lower end and the truss are connected using connecting hardware made of metal plate that is overlapped over the webs of both H-shaped steel beams that are to be joined, with bolts and nuts that fasten the overlapping parts. To connect the upper end of the munagi wood and the gable and the lower end of the gable and the truss, and to secure the purlin to the gable and corner gable, connecting hardware with a plate fixed to the upper end of a screw shaft is used. The connecting hardware is attached to the top of the munagi wood, truss, gable and corner gable with a screw shaft and nuts, and the purlin is fastened between the munagi wood and the truss, and on top of the gable and corner gable, using this connecting hardware and bolts and nuts. In this hipped roof truss construction method, connecting metal fittings are fixed upright to the top surface of each gable, and the purlins, which are placed at regular intervals in the vertical direction of the slope so that they cross over the top surface of each gable, are placed on the plates of these connecting metal fittings, and the overlapping parts are secured with bolts and nuts to complete the hipped roof truss. After this, roofing materials are laid directly on the purlins, or using rafters and sheathing boards to lay the roof materials.

JP 2007-211525 A

In buildings with hipped roofs and truss structures assembled using conventional construction methods, such as those exemplified in Patent Document 1, when a panelized construction method is adopted to allow for easy roof construction without fastening sheathing boards on-site, the roof surface becomes high due to the thickness of both the steel framework and the roof frame. In this case, it may conflict with the slope and height restrictions of the Building Standards Act. Furthermore, if the height of the fascia is to be kept constant or low from the perspective of the building design, it becomes necessary to increase the eaves projection. In this case, the area of the building when viewed from above increases, and the site adaptability may decrease. It may also become necessary to increase the cross section of the beams supporting the eaves. For this reason, it is desirable to provide a building with a hipped roof and truss structure that suppresses the height of the roof surface.

The present invention was made in consideration of the above situation, and its purpose is to provide a building with a hipped roof and truss structure that limits the height of the roof surface.

Based on the drawings, we will explain the building according to the embodiment of the present invention.

Figures 1 to 3 show a building 100 according to this embodiment. Figure 1 shows a perspective view of the building 100. Figure 2 shows an explanatory diagram of the structure of the roof portion of the building 100. Figure 3 shows a top view of the building 100. First, an overview of the building 100 will be described.

As shown in Figures 1 and 2, the building 100 comprises a corner post 3 and a roof panel 7 fixed to the corner post 3. As shown in Figure 2, the corner post 3 includes a T-shaped steel material in cross section when viewed along its extension direction, and is arranged so that its web 3a extends upward from the upper surface of the flange 3b. The roof panel 7 is fixed to its underside and has a fixing plate portion 72 that extends downward. The fixing plate portion 72 is fixed to the side of the web 3a. In this embodiment, the vertical direction is the same as the up-down direction, and below, below or above in the vertical direction will simply be referred to as below or above.

The building 100 is described in detail below.

As shown in FIG. 1, the building 100 has a hipped roof and truss structure. A specific example of the building 100 is a multi-story house with a steel frame. The building 100 may have multiple rooms. The building 100 may be composed of a reinforced concrete foundation, a framework made up of framework members such as columns and beams, and a superstructure fixed to the foundation, which has panels forming the walls, floors, etc. The framework members and panels of the building 100 may be standardized in advance. In this case, the framework members and the like can be manufactured in advance in a factory and transported to the construction site, where the building 100 can be assembled.

The building 100 may comprise a ridgepole 1, four or more purlin beams 2 arranged to surround the ridgepole 1 in top view, an R-floor floor F supporting each of the purlin beams 2 via purlin beams 20, a corner post 3 supported at its lower end by the R-floor floor F and at its upper end by the purlin beams 2, multiple roof panels 7 fixed to the corner posts 3, and a lower structure A supporting the R-floor floor F from below. Note that FIG. 1 illustrates some of the multiple roof panels 7 (only two panels are shown in FIG. 1).

The ridge beam 1 is a horizontal member that is hung at the highest point on the roof of the building 100. As described below, the ridge beam 1 is supported by corner beams 3, and does not necessarily need to be supported by ridge beams (true beams) or diagonal braces. The ridge beam 1 may be a steel frame such as an H-beam.

The R floor F includes an outer periphery floor beam 4 (hereinafter, sometimes referred to as floor beam 4) arranged to surround the outer periphery, an inner floor beam 5 (hereinafter, sometimes referred to as floor beam 5) that is suspended within the area surrounded by the outer periphery floor beam 4, and a floor plate 45 supported by the outer periphery floor beam 4 or the inner floor beam 5. The R floor F is supported by the lower structure A including the foundation of the building 100 and columns constructed on the foundation. The R floor F may be configured as a rigid floor that is stiffened against horizontal forces (horizontal forces) by the floor beams 4, 5. In the building 100, four or more outer periphery floor beams 4 (four as an example in FIG. 1) are arranged in a ring shape to surround the ridge beam 1 in a top view (see FIG. 3). The outer periphery floor beam 4 is a so-called girder beam supported by the columns of the lower structure A.

The purlin beams 2 are horizontal members that are positioned lower than the ridgepole 1 on the roof of the building 100 and are supported on the R floor F. The purlin beams 2 may be steel frames such as H-beams. In the building 100, four or more purlin beams 2 (four in FIG. 1 as an example) are arranged in a ring shape surrounding the ridgepole 1 when viewed from above (see FIG. 3). FIG. 1 shows an example in which the purlin beams 2, purlins 21 to 24, are arranged in a ring shape in this order.

In this embodiment, the purlins 21, 23 are arranged parallel to the ridge pole 1. The purlins 22, 24 are arranged in a direction perpendicular to the ridge pole 1. The purlins 21-24 are arranged between the ridge pole 1 and the outer periphery floor beams 4 when viewed from above. The purlins 21-24 are spaced apart from the ridge pole 1 when viewed from above. The purlins 21-24 are spaced apart from the outer periphery floor beams 4 when viewed from above.

The purlin beam 2 is supported by the floor beam 5 of the R floor F, and is supported by the floor beam 5 via the purlin beam 20 erected to extend vertically. In other words, the force applied to the purlin beam 2 in the vertical direction is supported by the floor beam 5 of the R floor F.

It is preferable that the purlin beam 2, purlin beam 20, and R floor F form a structural surface that resists horizontal forces along the extension direction of the purlin beam 2. In the example shown in Figures 1 and 4, the purlin beam 2, purlin beam 20, and floor beam 5 of R floor F form the structural surface. This structural surface may be a diagonal brace structure, a brace structure, a truss structure, or a rigid frame structure. Note that Figure 4 is a perspective view for explaining the support relationship of the purlin beam 2, purlin beam 20, and floor beam 5 of R floor F.

Figures 1 and 4 show an example in which the structural surface formed by the purlin beams 2, purlin beams 20, and floor beams 5 of the R floor F is a diagonal brace structure including diagonal braces 29. In other words, this structural surface is fixed to the purlin beams 2 and purlin beams 20, and diagonal braces 29 are arranged to span the structural surface parallel to and extending diagonally, forming a diagonal brace structure and providing a structural surface that resists horizontal forces along the extension direction of the purlin beams 2.

In the example shown in Figure 1, each of the four purlin beams 2 arranged in a ring is formed with a structural surface that resists horizontal forces along the extension direction of each purlin beam 2. This allows the building 100 to have these purlin beams 2 formed in a ring that can resist forces in any direction along the horizontal direction.

The purlin beam 2 supports the underside of the corner post 3, as described below.

The corner posts 3 are long structural members that are arranged along the slope of the roof and support the roof panels 7. The corner posts 3 are arranged along the peaks of the sloped portions of the roof of the building 100. When the corner posts 3 are arranged along the peaks of the sloped portions of the roof of the building 100, valley posts are arranged instead of the corner posts 3. In the following explanation, the explanation of the corner posts 3 is the same as for the valley posts when the corner posts 3 are replaced with valley posts.

The corner post 3 is arranged so that it intersects with the purlin beam 2 (for example, at a 45° angle) when viewed from above. The corner post 3 is a steel material with a T-shaped cross section when viewed along its extension direction. In this embodiment, as an example, the steel material of the corner post 3 is a CT steel. This embodiment illustrates a case where the corner post 3 is a CT steel. In the building 100, the corner post 3 is arranged so that its web 3a extends upward from the top surface of the flange 3b.

The corner post 3 is supported by the purlin beam 2. The corner post 3 may also be supported by the floor beam 4 located on the outer periphery of the R floor F. The corner post 3 may be supported by the purlin beam 2 and the floor beam 4.

The corner post 3 does not require a beam to support it. This allows the attic space of the building 100 to be secured as a large space that is not obstructed by structures such as beams.

Now, in the building 100, as described above, the force in any direction along the horizontal direction is formed in a ring shape, and the purlin beam 2 that constitutes the structural surface described above is structured to be able to resist it. In addition to this structure, by making the corner posts 3 supported by the purlin beams 2, if a force (thrust) or horizontal force is applied to the ridgepole 1, purlin beam 2, or corner post 3 due to a force (vertical force) along the vertical direction, these can be handled at the position of the purlin beam 2, so in the building 100, there is no need to place structures such as diagonal braces or beams (hereinafter referred to as beams, etc.) for the corner posts 3 that would hinder the use of the space in the attic, or the number of beams, etc. that are placed can be reduced. This makes it possible to ensure that the attic space of the building 100 is a large space that is not obstructed by structures such as beams, etc.

Figure 1 shows a case where the corner post 3 is supported at the corner where a pair of adjacent purlin beams 2, 2 intersect. It also shows a case where the corner post 3 is supported by the floor beam 4 at the lower end side of the part supported by the purlin beam 2.

The corner posts 3 support the ridge beam 1. In the building 100, the ridge beam 1 may be supported only by a number of corner posts 3. In more detail, the ridge beam 1 does not necessarily require ridge beams or diagonal braces (hereinafter, also referred to as beams, etc.) to support it. By supporting the ridge beam 1 with a number of corner posts 3 supported by the purlins 2 that constitute the above-mentioned structural surface, the number of beams, etc. supporting the ridge beam 1 may be reduced, and the ridge beam 1 may not have beams, etc. supporting it. Since the ridge beam 1 does not require beams, etc. such as ridge beams, or even if it is supported by beams, etc., the number of beams, etc. can be reduced, it becomes possible to ensure that the attic space of the building 100 is a large space that is not obstructed by structures such as beams, etc. In other words, the building 100 can ensure a large attic space.

As shown in Figure 2, the corner post 3 is supported by the purlin beam 2 and floor beam 4 with the web 3a of the CT steel on the underside and the flange 3b on the top side. In other words, the web 3a of the CT steel of the corner post 3 is arranged to extend upward from the top surface of the flange 3b. Note that Figure 2 is a schematic diagram of a cross section (II-II cross section in Figure 1) of the corner post 3 and roof panels 7, 7 as viewed along the extension direction of the corner post 3, in order to explain the structure of the roof part of the building 100.

The corner posts 3 support the ridgepole 1 at their upper ends. In this embodiment, the upper ends of the pair of corner posts 3, 3 are connected to one end of the ridgepole 1 in the extension direction, supporting one end of the ridgepole 1. In addition, the upper ends of a pair of corner posts 3, 3 other than the pair of corner posts 3, 3 supporting one end of the ridgepole 1 are connected to the other end of the ridgepole 1, supporting the other end of the ridgepole 1.

In the example shown in Figure 1, a pair of corner posts 3, 3, 31, 34, supports one end of the ridgepole 1, and another pair of corner posts 3, 3, 32, 33, supports the other end of the ridgepole 1. In this way, the ridgepole 1 is supported by four corner posts 3, as an example. As mentioned above, the corner posts 3 are supported by the floor beams 4 and the purlin beams 2. The purlin beams 2 are supported by the floor beams 5. In other words, the ridgepole 1 is supported by the R floor F via the corner posts 3.

In the building 100, the corner posts 31, 34 and one end of the ridge post 1 form a space truss. The corner posts 32, 33 and the other end of the ridge post 1 form a space truss. The space truss formed by these corner posts 3 and the end of the ridge post 1 allows the building 100 to firmly resist horizontal forces.

The corner post 3 is connected to the ridge post 1, purlin beam 2, and floor beam 4 with metal joints to support the ridge post 1, and may also be supported by at least one of the purlin beam 2 and floor beam 4. This allows the force acting in the vertical direction on the ridge post 1 or corner post 3 to be transmitted from the corner post 3 to the purlin beam 2 and then to the floor beam 5, or from the corner post 3 to the floor beam 4, i.e., from the corner post 3 to the R floor F.

Figure 5 shows a first joint metal 61 that joins the corner post 3 and the ridge post 1. The first joint metal 61 may have a base 61a that is fixed to the end of the ridge post 1 in the extension direction, and a plate portion 61b that has a plate surface that supports the bottom surface of the corner post 3 (the lower surface of the flange 3b). In Figure 5, the plate portions 61b, 61b are fixed to two adjacent side surfaces of the square column portion 61c fixed on the base 61a so that they incline downward as they move away from the base 61a. In this way, the first joint metal 61 realizes an arrangement in which the corner post 3 supports the end of the ridge post 1 and extends at an angle downward from the end of the ridge post 1 in the corner post 3. The flange 3b and the plate portion 61b may be joined using one or more bolts. The ridge post 1 and the base 61a may also be joined using one or more bolts.

Figure 6 shows a second joint metal 62 that joins the corner post 3, the ridge post 1, and the floor beam 4. The second joint metal 62 may have a base 62a that is fixed to the end of the floor beam 4 in the extension direction, and a plate portion 62b that has a plate surface that supports the bottom surface of the corner post 3 (the lower surface of the flange 3b). Figure 6 shows an example in which the second joint metal 62 further has a support plate portion 62c that extends from the side of the base 62a and intersects with the lower surface of the plate portion 62b at a right angle. The plate portion 62b is fixed to the base 62a so that it slopes downward as it moves away from the base 62a. As a result, the second joint metal 62 realizes an arrangement in which the corner post 3 is supported by the end of the floor beam 4 and extends at an angle downward in the corner post 3. The base portion 62a is a corner portion where the floor beams 4, 4 intersect, and may be supported by the outer side of the R floor floor F (floor beam 4). In this embodiment, the outside refers to the outside when viewed from above of the building 100 shown in FIG. 1. The flange 3b and the plate portion 62b may be joined using one or more bolts. The floor beam 4 and the base portion 62a may also be joined using one or more bolts.

Although not shown, the purlin beam 2 and the corner post 3 may be joined using a second joining metal 62 or a similar joining metal. That is, the joining metal that joins the purlin beam 2 and the corner post 3 may have a base that is fixed to the end of the purlin beam 2 in the extension direction, and a plate portion having a plate surface that supports the bottom surface of the corner post 3 (the lower surface of the flange 3b). The joining metal that joins the purlin beam 2 and the corner post 3 may be the corner where the purlin beams 2, 2 intersect, and may be supported by the outer side of the purlin beam 2.

The roof panel 7 shown in Figures 1 and 2 is a unit that constitutes the roof of the building 100. When constructing the building 100, the roof panel 7 may be pre-assembled at a location other than the construction site where the building 100 is to be constructed, for example, at a factory. After pre-assembly, the roof panel 7 may be transported to the construction site where the building 100 is to be constructed, and used in the construction of the building 100. In the building 100, the roof panel 7 is fixed to the corner post 3.

Figure 7 shows an example of a specific example of a roof panel 7. Figure 7 is a perspective view of the roof panel 7 viewed diagonally from below.

The roof panel 7 includes a sheathing board 70a and rafters 70b, and has a roof board section 70 that serves as the upper cover of the building 100, and a fastener L that is fixed in advance to the underside of the upper side of the roof board section 70 and is fixed to the corner post 3 when the building 100 is constructed. The roof panel 7 may have a fascia board 70c on the lower side of the roof board section 70. The roof of the building 100 may be constructed with multiple roof panels 7 arranged adjacent to each other. The rafters 70b are long members of the roof panel 7 that support the sheathing boards 70a. In the building 100, the rafters 70b may be supported only by the purlins 2 and floor beams 4.

The fastener L may be a long member arranged along the outer periphery of the roof board portion 70. The fastener L is arranged on the outer periphery of the roof board portion 70 in a position along the corner post 3 when the roof panel 7 is fixed to the corner post 3 as shown in FIG. 2. In other words, when the roof panel 7 is fixed to the corner post 3, the fastener L is arranged so that its longitudinal direction extends along the corner post 3.

The fixing device L may have a fixing plate portion 72 extending below the roof panel portion 70. The fixing plate portion 72 may be fixed to the side surface of the web 3a of the corner post 3. In other words, the fixing plate portion 72 is arranged with its plate surface aligned with the web 3a of the corner post 3. By joining the fixing plate portion 72 to the side surface of the web 3a, the vertical distance between the roof panel 7 and the corner post 3 is shortened, and the height of the roof surface of the building 100 can be reduced, i.e., the height of the roof from the R floor F can be kept low.

In building 100, the height of the roof from the R floor F can be kept low, so the area of the roof (area of building 100) when viewed from above can be reduced. This reduces the amount of land required to construct building 100. In other words, building 100 has a high site adaptability. In addition, because the area of the roof (area of building 100) when viewed from above can be reduced, the cost of constructing the roof can be reduced.

In the building 100, the height of the roof from the R floor F can be kept low, so the height of the fascia 70c can be reduced. This improves the design of the building 100.

In the building 100, the height of the roof from the R floor F can be kept low, so the overhang of the roof eaves (the distance from the side wall of the building 100 to the fascia 70c) can be shortened. This reduces the load on the floor beams 4 to support the roof eaves, making it possible to reduce the cost of the floor beams 4.

The fixing plate portion 72 may be fixed to the web 3a with a bolt B, for example, a bolt passing through the fixing plate portion 72 and the web 3a. The roof panel 7 is fixed to the corner post 3 by fixing the fixing plate portion 72 to the side of the web 3a.

In this embodiment, the fixture L may have a support plate portion 71 that is fixed to the roof plate portion 70 along the underside of the roof plate portion 70, the above-mentioned fixing plate portion 72 that extends downward from the support plate portion 71 to the roof plate portion 70, and a mounting plate portion 73 that extends from the tip of the fixing plate portion 72 and bends inward in the in-plane direction of the roof plate portion 70. The support plate portion 71, the fixing plate portion 72, and the mounting plate portion 73 may be integrally molded by bending a long plate material with two folds along the longitudinal direction so that the cross section viewed along the extension direction of the corner post 3 has an angular U-shape.

The fixing device L is fixed so that the support plate portion 71 is firmly fixed to the roof plate portion 70 by aligning the plate surface with the underside of the roof plate portion 70.

When the roof panel 7 is placed on the corner post 3 and fixed in place with the fastener L, the mounting plate portion 73 is placed on the upper surface of the flange 3b. This makes it easier to place the roof panel 7 on the corner post 3 and fix it in place.

As shown in Fig. 1 and Fig. 2, separate roof panels 7, 7 may be fixed to both sides of the web 3a (see Fig. 2) of the corner post 3. Fig. 1 and Fig. 2 show a case where the building 100 has a first panel 7A, which is a first roof panel 7, and a second panel 7B, which is a second roof panel 7 arranged adjacent to the first panel 7A. In this case, as shown in Fig. 2, at the butt joint C where the first panel 7A and the second panel 7B are adjacent, the shape of the upper surface side of the roof becomes a ridge along the extension direction of the corner post 3. In other words, at the butt joint C, the outer surface of the roof becomes a convex shape. At the butt joint C, the fixing plate portion 72 of the first panel 7A is fixed to the first side of the web 3a. Also, the fixing plate portion 72 of the second panel 7B is fixed to the second side of the web 3a to which the first panel 7A is fixed.

In this way, it is possible to provide a building with a hipped roof and truss structure that keeps the roof surface height low.

[Another embodiment]
(1) In the above embodiment, the roof panel 7 is supported by the corner posts 3. However, the roof panel 7 may be supported by the corner posts 3 and the valley posts, or by the valley posts only.

(2) In the above embodiment, four corner posts 3 are described. However, there may be five or more corner posts 3 and valley posts.

(3) In the above embodiment, a case has been described in which all (four) corner posts 3 are supported by the floor beams 4. However, the building 100 may have corner posts 3 or valley posts that are supported by at least the purlin beams 2 and not supported by the floor beams 4.

(4) In the above embodiment, when separate roof panels 7, 7 are fixed to both sides of the web 3a of the corner post 3, the shape of the upper surface of the roof at the butt joint C is a ridge that runs along the extension direction of the corner post 3. However, when separate roof panels 7, 7 are fixed to both sides of the web of the valley post instead of the corner post 3, the shape of the upper surface of the roof at the butt joint C is a valley that runs along the extension direction of the valley post.
