Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a ridge when the ridge roof is cut into two divided bodies on a plane perpendicular to the ridge line direction at one of the vertices at both ends of the ridge. The present invention relates to a roof structure for forming a roof having substantially the same shape as that of the other divided body.

[0002]

BACKGROUND ART In general, floors, walls,
2. Description of the Related Art A prefabricated house using a panel construction method in which a roof is formed by assembling a plurality of floor panels, wall panels, and roof panels, respectively, is known. Each of the above-mentioned panels includes, for example, a rectangular frame, a support member arranged vertically or horizontally or in either direction in the frame, and a face plate attached to at least one side surface of the frame. , Basically wooden. Some panels have shapes other than rectangles, and materials other than wood are used.

[0003] In a roof of a house using the panel method, each roof panel constituting the roof surface is composed of a wall extending upward to a lower side of the roof surface and a beam bridged between the walls. Supported by For example, in the case of a gable roof, for example, the upper parts of the left and right wife walls of the house are formed in a triangular shape, and the upper edges of the wife walls, that is, the left and right oblique sides, are joined together with the roof panel mounted thereon. In addition, if there are walls along the ridge or walls perpendicular to the ridge between the two wife walls, and there are walls that extend below the roof surface, a roof panel shall be mounted on the upper edge of these walls. It is joined in the state. Also,
A beam is bridged over the upper edge between the walls that are orthogonal to the building and adjacent to each other, and a roof panel is also mounted and supported on the beam.

When a roof panel is mounted on a wall or a beam arranged parallel to a ridge, a roof surface formed by the roof panel or the roof panel may extend in a direction perpendicular to the thickness direction of the wall or the axial direction of the beam. It is necessary to incline the upper surface of the wall or the beam so as to match the roof surface, and a binder having a triangular cross section is mounted on the wall or the beam. In addition, the ridge roof has a complex shape with four roof surfaces, while the gable roof has two roof surfaces.However, the structure for supporting the roof surface of such a ridge roof should be simple. For this purpose, the roof surface is supported by diagonally inclined beams in addition to walls and horizontal beams. In addition, the oblique beam and the horizontal beam are joined and used so as to be linear in a plan view. By using such beams, various beams and bundles arranged in the back of the hut can be reduced to widen the back of the hut, increase the ceiling, and widen the space behind the hut to effectively use it as a storage space, etc. be able to.

[0005]

By the way, in a house, the entire roof is used as a roof by making the entire roof a flat roof, or a part of the roof is used as a roof roof as a flat roof. . In such a case, for example, by forming a penthouse with a sloped roof for entering and exiting the roof, and by the presence of a sloped roof in the rest of the roof balcony, the land roof and the sloped roof are adjacent to each other State.

In such a case, as the shape of the sloped roof, for example, a gabled roof or a shape obtained by cutting a ridge roof with a plane orthogonal to the ridge can be considered. Then, at one of the vertices at both ends of the building, the ridge roof is cut into two divided bodies on a plane perpendicular to the ridge line direction. When the roof of the shape is formed, the roof is an isosceles triangular wife wall, and two first roofs consisting of right triangles arranged on the two oblique sides of the wife wall along the sides perpendicular to the base respectively. And a second roof surface having an isosceles triangular shape in which the right and left oblique sides are respectively arranged along the oblique sides of the two first roof surfaces.

The second roof surface having an isosceles triangular shape is in a state where its apex portion is placed on the apex portion of the end wall obliquely along the thickness direction of the end wall. And when the said 2nd roof surface consists of several roof panels, and a 2nd roof surface is supported by a wall and a beam, the roof panel arrange | positioned at the vertex part of a 2nd roof surface Will be supported in the state of being mounted on the wall, but since the roof panel is mounted on a small portion of the top of the wall, it is difficult to support only with the wall, for example, Had to do the framing to support the roof panels.
However, in this case, there is a problem that the support structure for the roof surface becomes complicated, costs are increased, and the space behind the cabin is narrowed.

The top wall of the second wall has an isosceles triangle when viewed from the front, and the top of the second roof surface, which is inclined in the thickness direction of the bottom wall, is supported by the top of the top wall. In order to do so, it is necessary to also make the vertex portion of the wife wall oblique along the thickness direction. For example, assuming that the apex portion of the wife wall is cut diagonally, and the wall panel constituting the apex portion of the wife wall is formed of a triangular frame and face plates respectively attached to both surfaces thereof, Sharpening the apex portion of the end wall is not preferable because the frame and face plate of the hollow wall panel are basically shaved, and it is not preferable to cut and form the wall panel having the above-described configuration. It is more difficult than shaving and shaping a flat plate-shaped member. Therefore, if the apex portion of the wall panel is inclined along the thickness direction, it is preferable to make the shape of the wall panel into a shape in which the apex portion is oblique as described above at the time of manufacturing the wall panel, Then, the shape of the wall panel to be manufactured becomes complicated and the number of types of the wall panel to be manufactured increases, which may cause an increase in the manufacturing cost of the wall panel.

The present invention has been made in view of the above circumstances, and has a simple and easy-to-install roof in order to construct a roof having a shape obtained by cutting a building roof by a plane perpendicular to the ridge line. It is intended to provide a structure.

According to the above configuration, the apex portion of the second roof surface 5 formed from the roof panels 5a, 5b, 5c is supported on the apex portion of the end wall 3, ie, the apex of the end wall 3 Although a small area of the portion supports the vertex side of the second roof surface 5, the reinforcing member 8 allows the second roof surface 5 to be supported.
Of the second roof surface 5 can be stably supported. Therefore, it is not necessary to use a frame or the like to stably support the vertex side of the second roof surface 5, and the second structure has a simple configuration in which a reinforcing member is simply attached to the top of the indoor side surface of the end wall 3. Since the top side of the roof surface 5 can be stably supported, the cost can be reduced and the roof can be easily constructed.

Anything that can support the fourth and second roof surfaces 5 is acceptable,
It is preferable to be formed from a wall panel used in the above-mentioned conventional panel construction method. The reinforcing member 8 is basically joined to the end wall 3 and supported by the end wall 3, and the upper surface thereof is formed along the second roof surface 5, and the end wall 3 of the second roof surface 5 is formed. What is necessary is just to be the shape which enlarges the part supported by. Also, if the ridge roof is cut into two halves on a plane perpendicular to the ridge line direction at one of the vertices at both ends of the ridge, the same as the split body that does not include the ridge The sloped roof 1 having a shape basically includes a shape obtained by substantially equally dividing a square roof having a square shape in a plan view into two planes parallel to two sides parallel to each other among four sides thereof.

When the apex portion of the wall 3 is cut obliquely, not the wall panels 3a, 3a but the upper end of the prism 7 may be cut.

Therefore, it is not necessary to cut off the vertices of the triangular wall panels 3a, 3a. If the prism 7 is made of, for example, a substantially uniform material, the strength is reduced even if the upper surface thereof is cut obliquely. There is nothing. Further, when the wall panels 3a, 3a are made of a plurality of members and the prisms 7 are made of a homogeneous material, it is easier to process the prisms 7 than to process the wall panels 3a.

There is no need to further arrange beams or bundles for support, and the space behind the cabin is not narrowed by the beams or bundles for supporting the first beams 9. In addition, the second beam 10
Is preferably supported by the two first beams 9, 9. That is, it is preferable that both ends of the second beam 10 are joined and supported by the left and right first beams 9, 9. In this case, in order to support the second beam 10, Further, there is no need to arrange beams or bundles, and the space behind the cabin is not narrowed by beams or bundles for supporting the second beams 10.

The third means for solving the above-mentioned problem is that the third beams 11, 11 and the first beams 9, 9 are joined in a substantially straight line in plan view. According to the above configuration, since the lower part of the second roof surface 5 is supported by the oblique third beam 11, it is not necessary to combine beams and bundles in a complicated manner to support the second roof surface 5. The space behind the hut can be widened.

The first beams 9, 9 supporting the first roof surfaces 4, 4 and the third beams 11, 11 supporting the lower portion of the second roof surface 5 are substantially aligned in plan view. The first beams 9, 9 and the third beams 11, 1

Slope roof 1 with the same shape as the divided body without the ridge
And a flat roof 2. The sloped roof 1 has an isosceles triangular shaped masonry wall 3 and two first roof surface portions each composed of a right-angled triangle arranged along two oblique sides of the masonry wall 3 with sides perpendicular to the bottom side. 4 and 4, and a second roof surface portion 5 having an isosceles triangular shape, which is arranged with the left and right oblique sides along the oblique sides of the two first roof surface portions 4 and 4, respectively.

The flat roof 2 is formed of a substantially flat surface with a slight water gradient. The land roof 2 is disposed adjacent to the end wall 3 of the sloped roof 1, and the land roof 2 is lower than the lower end of the sloped roof 1. The horizontal width of the sloped roof 1 and the flat roof 2
Are substantially the same as each other, and when viewed in plan, the combined portion of the sloped roof 1 and the land roof 2 has a square or rectangular shape. In this example, the outer wall 6 of the house having the roof structure is higher than the lower ends of the land roof 2 and the sloped roof 1 so as to surround the outer periphery of a portion where the sloped roof 1 and the landed roof 2 are combined. The upper end of the outer wall 6 is a parapet.

The rear wall 3 of the sloping roof 2 is shown in FIG.
And as shown in FIG. 4, triangular or square wall panels 3a, 3a, 3b, 3b, 3c, 3c, 3d, 3
d, the opening adjusting members 3f and 3g disposed below and above the opening 3e for entering and exiting from the flat roof, and the left and right ends of the opening adjusting member 3g on the opening 3e. 3h, 3h arranged on both left and right side edges of the opening 3e
And

The upper portion of the end wall 3 is made into an isosceles triangle shape by joining the perpendicular sides of the two right-angled triangle wall panels 3a, 3a, for example. In the above, a regular angle 7, which is a prism having a square cross section, is arranged between the wall panels 3a, 3a. The regular angle 7 has substantially the same thickness as the wall panels 3a, 3a. The wall panels 3a, 3a, 3b, 3b, 3c, 3
c, 3d, 3d and the opening adjusting members 3f, 3g have substantially the same thickness.

As shown in FIG. 4, the upper end of the regular angle 7 is obliquely cut corresponding to the right and left oblique sides of the end wall 3 with the left and right central portions as boundaries. Slope 7
a, 7a are formed, and are in the shape of an isosceles triangle when viewed from the front. Further, a part closer to the indoor side than the half of the upper end of the regular angle 7 is cut off diagonally to form a slope 7b. Therefore, the upper end of the regular angle 7 has the left and right central portions as boundaries and the uppermost portion, and the trapezoidal slopes 7a, 7a which fall downward as the distance from the central portion increases, and the central portions before and after the trapezoidal slopes 7a, 7a. And an isosceles triangular slope 7b.

The inclined surfaces 7a, 7a of the regular angle 7 have the same inclination angles as the left and right oblique sides of the upper part of the end wall 3, and are flush with the two upper surfaces of the end walls 3, which are these oblique sides. ing. Therefore, the slopes 7a, 7a have the same inclination angle as the left and right first roof surfaces 4,4. The slope 7 b having the regular angle 7 has the same inclination angle as the second roof surface 5. And, on the left and right slopes 7a, 7a of the regular angle 7,
The upper ends of the left and right first roof surfaces 4, 4 are respectively joined. Also, on the slope 7b of the regular angle 7,
The upper end of the second roof surface 5 is joined.

The regular angle 7 is a wooden lumber, and its tip can be easily processed to form the slopes 7a, 7a and 7b. Because it is almost homogeneous (there is some difference because it is wood)
Even if the above-described processing is performed, a large change in strength does not occur. That is, in the above-described wall panel, it is difficult to perform a process of deleting a part of the frame, but in the case of the regular angle 7, the process can be easily performed.

Then, on the inner surface of the wife wall 3 as described above,
At a position corresponding to the regular angle 7, a reinforcing material 8 having substantially the same lateral width as the regular angle 7 and having the same vertical length as the regular angle 7.
Are joined. The reinforcing member 8 is a slope 8a whose upper surface becomes lower as it goes indoors. The slope 8a of the reinforcing member 8 has the same inclination angle as the slope 7b of the regular angle 7. When the reinforcing member 8 is joined to the indoor side surface of the rear wall 3 at the position of the regular angle 7, the slope 8 a of the reinforcing member 8 is continuous with the lower side of the slope 7 b of the regular angle 7, and the reinforcement is performed. The inclined surface 8a of the member 8 and the inclined surface 7b of the regular angle 7 are substantially flush with one another.

Then, the portion where the upper end of the second roof surface portion 5 is joined by the reinforcing member 8 is a combination of the slope 7b of the regular angle 7 and the slope 8a of the reinforcing member 8, and Wife wall 3 for joining the upper end of surface 5 to wife wall 3
The area of the joint surface between the second member and the second roof surface 5 is increased by the area of the slope 8 a of the reinforcing member 8. Accordingly, the joining strength between the second roof surface portion 5 and the rear wall 3 can be improved, and the second roof surface 5 by the rear wall 3 in a more stable state.
Can be supported.

The upper portions of the left and right first roof surfaces 4, 4 are respectively triangular roof panels 4 a, 4 b, quadrangular roof panels 4 c, and a roof adjuster disposed on the keraba portion of the end wall 3. 4d, 4d, and these are integrally joined to a roof panel (not shown) constituting the lower part of the first roof surface portions 4, 4. In addition, the upper part of the second roof surface part 5 has triangular roof panels 5a, 5a.
a, 5b, 5b and a rectangular roof panel 5c, which are integrally joined to a roof panel (not shown) constituting a lower portion of the second roof surface portion 5. Each roof panel includes a triangular or quadrangular frame (not shown), and a longitudinal or horizontal or any one-way member (not shown) arranged in the frame according to the size.
And a surface material (not shown) attached to the upper surface of the frame.

The upper portions of the one roof surface portions 4, 4 are supported on the horizontal beams 9, 9 orthogonal to the end wall 3. In addition, on the beams 9, a binding material (not shown) having a cross section of a right-angled triangle and an inclination angle of the hypotenuse of which is substantially equal to an inclination angle of the first roof surface portions 4, 4 is arranged. The first roof surface portions 4 and 4 and the beams 9 and 9 are joined via a bonding material.

The second roof surface 5 is joined with its apex placed on the slope 7 b of the regular angle 7 and the slope 8 a of the reinforcing member 8 arranged on the top of the end wall 3. The second roof surface portion 5 is mounted on beams 10, 11 which are parallel and horizontal to the rear wall 3 and beams 11, 11 which are inclined at right angles to the rear wall 3 in plan view. Supported in state. In addition, on the beam 10, a binder (not shown) whose cross section is a right-angled triangle and whose inclined side has an inclination angle substantially equal to the inclination angle of the second roof surface portion 5 is arranged, and the joining material is interposed therebetween. Thus, the second roof surface portion 5 and the beam 10 are joined.

The beam 11 has an inclination angle substantially equal to that of the second roof surface portion 5 so that the beam 11 and the second roof surface portion 5 are directly joined. In addition, each roof panel 4
a, 4b, 4c, 5a, 5b, 5c and beams 9, 10, 11
And the connection with the wife wall 3, basically the roof panels 4a, 4b,
4c, 5a, 5b, and 5c are performed by joining the frame members or the members. The beams 9 and 11 are joined to each other so as to be substantially straight when viewed in plan.
As shown in FIG. 7, an integral inclined beam 12 is formed from the beam 9 and the beam 11. The joint between the beam 9 and the beam 11 is formed on the left and right side surfaces thereof from the beam 9 to the beam 11, respectively.
3 is reinforced.

The beam 12 composed of the beam 9 and the beam 11
Is supported by the end wall 3 and the outer wall 6 because the end on the side of the beam 9 is joined to the end wall 3 and the end on the side of the beam 11 is joined to a portion of the outer wall 6 facing the end wall 3. Have been. In addition,
The joint between the end wall 3 and the outer wall 6 and the beam 12 is formed by a beam receiving hardware (not shown) for joining the beam and the wall. Further, the beam 10 is supported in a state where the left and right ends are respectively joined to the two beams 12, 12 arranged in parallel with each other and bridged between the two beams 12, 12. Have been. Note that both ends of the beam 10 are
The second beam 9 and the beam 11 are joined to each other.

On the beams 9, 9, the roof panels 4a, 4a of the first roof surface portions 4, 4 and the roof panels 4c, 4c,
c are joined, and the roof panels 5a, 5a of the second roof surface portion 5 and the roof panel 5c are joined on the beam 10,
On the beam 11, the roof panels 5c of the second roof surface portions 4, 4 and the roof panels 5b, 5b are joined, and the side edges of each roof panel are placed on the beams 9, 10, 11 respectively. It is to be supported in the state that was set.

The above-mentioned flat roof 2 is formed by a floor panel (not shown) supported on the wall of the second floor, and a horizontal surface formed by the floor panel is provided with a water gradient. The flat body constitutes an upper surface of the flat roof 2, and the flat body constitutes a floor surface of the flat roof 2 used as a roof balcony (rooftop).

The floor panel (not shown) is basically a rectangular frame, vertically and horizontally or in any one direction disposed in the frame, and attached to the upper surface of the frame. It consists of face materials. The outer wall 6 is basically composed of a wall panel (not shown). The wall panel includes a rectangular frame and a longitudinally or horizontally or one-way member disposed in the frame. , And surface materials stuck on both side surfaces of the frame body, respectively.

Next, the operation of this example of the roof structure having the above-described configuration will be described. As described above, the sloped roof having a shape obtained by cutting the ridge roof and having no ridge is used as the roof panels 4a, 4b, 4c, 4d, 5a, 5b, 5c.
In the case where the second roof surface portion 5 is formed from a panel such as the above, for example, the top of the second roof surface portion 5 is supported while being placed on the top portion of the end wall 3, and the second roof surface portion 5 and the Wall 3
Are joined to each other, and the area of the joining surface of the joining portion becomes inevitably small, for example, only the slope 7 b of the regular angle 7 is attached. However, the above-described reinforcing member 8 is attached to the top of the end wall 3. As a result, the second roof surface 5 of the wife wall 3
Is the slope 7b of the regular angle 7 and the slope 8a of the reinforcing member 8, and supports the second roof surface 5, that is, the joint surface between the second roof surface 5 and the end wall 3. , The bonding strength can be improved and stabilized.

At the top of the end wall 3, the tops of the two first roof surfaces 4, 4 having different inclination directions and the top of the second roof surface 5 are joined.
The top of the wife wall 3 has three slopes (slope 7a, 7a, 7b)
It is necessary to provide a process for forming the above-mentioned slope, but when the top of the end wall 3 is formed of the above-described wall panel, the frame portion of the wall panel is processed. However, since it is extremely difficult to process the frame portion of the wall panel without reducing the strength of the wall panel, it is necessary to form the wall panel from the beginning with the above-described slope formed, This can increase the cost of wall panels.

On the other hand, as described above, by using the regular angle 7, which is a square bar, instead of the wall panel at the top portion of the end wall 3 as described above, the strength of the slope 7a can be easily reduced without lowering the strength. , 7a, 7b. That is, by using the reinforcing member 8 and the regular angle 7 as described above, a shaft assembly for supporting the first roof surface portions 4 and 4 and the second roof surface portion 5 on the top portion of the sloped roof 1 is performed. This eliminates the need for a simple structure.
Can support the tops of the first roof surface portions 4 and 4 and the second roof surface portion 5. Therefore, it is possible to reduce the construction cost of the sloped roof 1 having the roof structure as described above, to save labor for the construction, and to shorten the construction period.

The upper portions of the first roof surfaces 4, 4 are supported by the rear wall 3 and the beams 9, 9 orthogonal to the rear wall 3, and the second roof surface 5 is connected to the rear wall 3, the rear wall 3 And a beam 11 inclined along the second roof surface 5, and the beams 9, 9 and the beams 11, 11 are integrally joined to form a beam 1.
2, 12 and the beams 12, 12 are
And the beam 10 is supported by the beams 12, 12, so that the upper portion of the first roof surface portions 4, 4 and the upper portion of the second roof surface portion 5 are supported. Is basically supported by the end wall 3 and the beams 9, 10, 11, and is configured such that another beam or bundle is not arranged to support the beams 9, 10, 11. The first roof surface portions 4 and 4 and the second roof surface portion 5
The space behind the hut below is large and can be used effectively. Further, the support structure itself for the roof surface can be extremely simplified, so that the construction cost can be reduced, the labor for the construction can be reduced, and the construction period can be shortened.

The sloped roof 1 as described above is used in combination with the flat roof 2 as a top floor where a roof balcony can be accessed and / or used as a penthouse for entering and exiting a rooftop. By cutting off a part of the roof, it becomes a novel design that gives the impression of forming a roof balcony (rooftop), it is extremely excellent in design, and the roof has such an excellent shape in design Can be constructed very easily as described above. Furthermore, by making the outer wall 6 project higher and higher than the lower end of the sloped roof 1 and the flat roof 2 to form a parapet, it is possible to further improve the design.

According to the roof structure of the first aspect of the present invention, the apex portion of the second roof surface formed of the roof panel is supported on the apex portion of the end wall, that is, the end wall is provided. The top surface of the second roof surface is supported by the small area of the top portion of the second roof surface, but the reinforcement member can support the vicinity of the top surface of the second roof surface. Can be stably supported. Therefore, it is not necessary to use a frame or the like to stably support the vertex side of the second roof surface, and the second roof surface has a simple configuration in which a reinforcing member is simply attached to the top on the inner surface side of the end wall. Can be stably supported, so that cost can be reduced and roof construction can be facilitated.

According to the roof structure of the second aspect of the present invention, the vertex of the rear wall is a prism, and the second roof surface is inclined at the vertex of the rear wall along the thickness direction of the rear wall. When the apex portion of the end wall is cut obliquely to support the upper wall, not the wall panel but the upper surface of the prism body may be cut. Therefore, it is not necessary to cut off the apex of the triangular wall panel, and if the prism is made of, for example, a substantially uniform material, the strength does not decrease even when the upper surface is cut diagonally. Also, when the wall panel is composed of a plurality of members and the prism is made of a homogeneous material, it is easier to process the prism than the wall panel, and to improve the workability and strength. Can be.

According to the roof structure of the third aspect of the present invention, the upper part of the first roof surface is supported by one of the left and right hypotenuses of the rear wall and the first beam orthogonal to the rear wall. And
The upper part of the second roof surface is supported by the top of the end wall, the reinforcing member, and the second beam parallel to the end wall. Here, since the vertex portion of the second roof surface is stably supported by the top of the rear wall and the reinforcing member as described above, the upper portion of the second roof surface is connected to the top of the rear wall, the reinforcing member and the rear member. It can be supported stably by the second beam parallel to the wall.

According to the roof structure of the fourth aspect of the present invention, the lower part of the second roof surface is supported by the third oblique beam, so that the second roof surface is supported by the beam or the like. There is no need to combine bundles in a complicated manner, and the space behind the hut can be widened. According to the roof structure of the fifth aspect of the present invention, the flat roof portion is a rooftop or a roof balcony, and the sloped roof is a penthouse for ascending or descending to the rooftop, or a top floor using a hut behind a roof balcony. be able to. And since such a sloped roof facing a rooftop or a roof balcony has a shape in which the ridge roof is divided by a plane orthogonal to the ridge, it can be made to be excellent in design, and such a design can be obtained. Can be simplified by using the reinforcing member as described above.
