The application target of the roof structure according to the present invention includes a cycle port, a corridor, and the like in addition to the carport. Hereinafter, embodiments applied to the carport, which is a typical application target, will be described.
In the present specification, the terms meaning the front-rear direction are expressed as "front" or "front end" with reference to the left side in FIGS. 1 and 2, and "rear" or "rear end" with reference to the right side. To do. The term meaning up and down is expressed with reference to the up and down direction of each figure. The reference numeral GL in FIG. 2 indicates the ground surface.

(Structure of roof structure)
Reference numeral A shown in FIGS. 1 and 2 is a carport, and the roof 1 and the support column 2 are the main components.
The roof 1 is attached and fixed to a pair of left and right columns 2 and 2 at the rear end. The front end of the roof 1 is a free end.

In the present invention, the number of columns 2 supporting the roof 1 may be two or more, and the number is not limited. For example, when the left and right dimensions of the roof are large, a plurality of columns 2 may be provided between the pair of left and right columns 2.

The roof 1 is a known member in which a flat roof member 1e is fixed to a frame member 1d composed of a beam 1a, a purlin 1b, and a rafter 1c. It should be noted that the present invention includes a roof having any structure as long as it functions as a roof without using the frame material 1d or the roof material 1e as shown in the drawing.
In the present invention, an extruded aluminum profile is used for the beam 1a, purlin 1b, and rafter 1c, but the present invention is not limited to this, and any material can be used.
In the present invention, a transparent roofing material 1e made of a synthetic resin such as polycarbonate is typically used, but the roofing material 1e is not limited to this and any material can be used.

The columns 2 and 2 are used as a pair on the left and right, but they are members having the same configuration. Therefore, in the following, one of the columns 2 will be represented and its configuration will be described.

As for the connection between the upper end portions of the columns 2 and 2 and the rear end portion of the roof 1, known means may be arbitrarily used. That is, a known method such as inserting an L-shaped insertion fitting into the hollow portion of the beam 1a and the hollow portion of the support column 2 and bolting them is typically used. Further, any other joining method can be adopted. For example, the lower end surface of the beam 1a is connected to the upper end surface of the support column 2, or the upper end surface of the support column 2 and the upper end surface of the beam 1a are substantially flush with each other. Those combined in this way are also included in the present invention.
The lower end portion 2b of the support column 2 is fixed to the concrete foundation 5 in the ground.

Gutters 4 are attached to the rear ends of the roof 1 and the rear surfaces of the columns 2. The gutter 4 includes a horizontal gutter 4a attached to the rear end of the roof 1 and a vertical gutter 4b attached to the rear surface of the support column 2. The gutter 4 may be different from the one shown in the drawing, and the one in which the gutter 4 does not exist is also included in the present invention.

As shown in FIGS. 1 and 2, the feature of the present invention is that in a roof structure in which the columns 2 are inclined, two column members 21 and 22 which are constituent members of the columns 2 are connected by a vertical connecting member 10. In the configuration.
In the present embodiment, the inclination of the support column 2 is such that the upper end of the support column 2 is located on the rear side and the lower end of the support column 2 is located on the front side. In the present specification, such an inclination may be referred to as "backward inclination". The rear end of the concrete foundation 5 is located in front of the rear end of the roof 1.
The vertical connecting member 10 is a member provided so as to be perpendicular to the horizontal ground surface GL when the support column 2 is properly inclined at a desired angle.

(Structure of pillar)
As shown in FIGS. 2 and 3, the column 2 has a configuration in which two column members 21 and 22 are arranged in parallel and connected by a vertical connecting member 10 and assembled to one column. Each of the pillar materials 21 and 22 is an extruded shape material made of aluminum, which has an advantage that it is lighter in weight and has excellent weather resistance as compared with steel or the like. The cross section is generally rectangular.
In the column 2 of the present embodiment, two column members 21 and 22 are used as strength members, and usually, a cover for making the appearance beautiful is attached to the column members 21 and 22. The support column 2 shown in FIG. 2 shows a state without a cover, and the support column 2 shown in FIG. 3 shows a state in which the inside (meaning the side where the support columns 2 face each other) has no cover and the outside has a cover. There is.

The upper ends of the pillar members 21 and 22 are connected to the beam 1a of the roof 1 as described above. The lower ends of the pillar members 21 and 22 are connected by the lower end connecting member 25, and slightly above the lower end (the position where the ground surface is GL at the time of installation), they are connected by the ground contact surface connecting member 23.
By being connected in this way, the two pillar members 21 and 22 are integrally fixed while maintaining the shape of a parallelogram that is long in the vertical direction.

(Vertical connecting material)
The vertical connecting member 10 may be any material as long as it can connect the two pillar members 21 and 22, and the material and shape are not particularly limited. Examples of the material include resin, metal such as steel and aluminum, and the like. The shape preferably has at least one vertical surface (plane perpendicular to the ground surface) in the front-rear direction and the left-right direction, and examples thereof include an L-shaped, U-shaped, and rectangular cross section.

In the present embodiment, as shown in FIGS. 3 and 4, the vertical connecting member 10 is a member made of a steel angle member. Both ends of the vertical connecting member 10 are attached to the pillar members 21 and 22 with screws 11. Also in FIG. 3, the outside of the two columns 2 is shown with the cover 30 attached, and the inside is shown with the cover not attached. In FIG. 4, the right side of the column members 21 and 22 shows the state where the cover 30 is attached, and the left side (the side where the vertical connecting member 10 is attached) shows the state where the cover is not attached.

In the present embodiment, the vertical connecting member 10 is provided perpendicularly (or at right angles) to the horizontal ground surface GL. This means that the vertical connecting member 10 becomes perpendicular to the horizontal ground surface GL when the column 2 is installed accurately with respect to the ground surface GL at a desired angle.

Therefore, by pressing a spirit level or the like, which is one of the tools used at the time of construction, against the vertical connecting member 10 and checking the verticality using the display function of the spirit level, the column 2 can be accurately tilted to a desired angle. It becomes easy to construct. Of course, the vertical connecting member 10 itself may be a member having a function like a spirit level, and such a vertical connecting member 10 is also included in the present invention.

As described above, the ground contact surface connecting members 23 and 23 shown in FIG. 5 are connected to the roots of the two pillar members 21 and 22, that is, the positions that serve as the ground surface GL. The ground contact surface connecting members 23 and 23 are known angle members, and are attached to the inside and outside of the two pillar members 21 and 22 by screws 24 and 24. In FIG. 5, the left side is the inside of the column 2 (column members 21 and 22), and the right side is the outside. The outside shows the state where the cover 30 is attached, and the inside shows the state where the cover is not attached.

The lower end connecting members 25 and 25 shown in FIG. 6 are connected to the lower ends of the columns 2, that is, the two pillar members 21 and 22, respectively, on the outer side and the inner side. The lower end connecting members 25 and 25 are steel angle members, and their width dimensions are larger than those of the ground contact surface connecting members 23 and 23. The lower end connecting members 25 and 25 are attached to the outside and the inside of the two pillar members 21 and 22 by screws 26 and 26.

The lower end connecting member 25 and the ground contact surface connecting member 23 are provided horizontally with respect to the horizontal ground surface.
By using a member (angle member) having an L-shaped cross section as the lower end connecting member 25, the contact area with the installation surface is increased. Therefore, when the support column 2 is erected in the foundation, the lower end connecting member 25 can function like a leg, so that the support column 2 can be erected stably when temporarily installed, and the construction is easy. become.

By using the lower end connecting member 25 having an L-shaped cross section, the contact area with the installation surface is increased, and the column 2 can be formed without processing the lower ends of the column members 21 and 22 horizontally with respect to the installation surface. It can be erected stably when temporarily installed. Therefore, the manufacturing cost (particularly, the processing cost) of the pillar materials 21 and 22 can be suppressed. Further, since the cross section of the lower end connecting member 25 is L-shaped, the contact area with the foundation can be increased in the horizontal direction, so that the vertical force generated in the support column 2 can be efficiently transmitted to the foundation. .. Therefore, the strength of the roof structure can be increased.
Further, by using a steel member as the lower end connecting member 25, the center of gravity of the support column 2 is moved downward. Therefore, when the support column 2 is temporarily installed, it can be erected stably, and the construction becomes easy.

In the column 2 of the present embodiment, as shown in FIGS. 3 and 4, the vertical connecting member 10 fixes the two column members 21 and 22 to each other and restrains the vertical separation, and the ground contact surface connecting member. Since the 23 and the lower end connecting member 25 restrain the two pillar members 21 and 22 from being separated in the horizontal direction, there is also an effect that the rigidity of the pillar 2 is increased.

(Construction method of roof structure)
(1) Preparation of the support column 2 In order to obtain an assembly of the support column 2, the lower end connecting member 25, the ground contact surface connecting member 23, and the vertical connecting member 10 are attached to the two column members 21 and 22. The cover 30 is attached to the outside of the support column 2 and not to the inside.
The work up to this point may be performed at the factory before construction or at the construction site.
It is preferable that the frame member 1d of the roof 1 is attached before the erection work of the support column 2.

(2) Standing of pillars A foundation hole is dug in the place where the pillars 2 are installed, concrete is poured, and after hardening, the pillars 2 are erected. At this time, the support column 2 is tilted to a desired angle, and whether or not the angle is exactly the desired value can be determined by placing a spirit level on the vertical connecting member 10 and checking whether or not the support is vertical.
When the vertical connecting member 10 becomes vertical, the column 2 is temporarily fixed with a temporary column or the like. In this state, pour concrete into the foundation hole. Then, concrete is poured to the lower surface of the ground contact surface connecting member 23 to form the foundation 5, and the foundation 5 is waited for hardening.

(3) Construction of columns When the concrete of the foundation 5 is hardened, the construction of columns 2 is completed. After that, the temporary pillars and the like are removed. After that, the cover 30 is attached to the support column 2 or the gutter 4 is attached. In addition, the roofing material 1e is attached. This completes the construction of roof structures such as carports.

According to the construction method of the present embodiment, when a spirit level, which is a construction tool, is applied to the vertical connecting member 10 and it is confirmed that the vertical connecting member 10 is perpendicular to the ground surface, the support column 2 is placed on the ground surface. On the other hand, it can be confirmed that the tilt is exactly the desired angle. Therefore, the construction of the carport A becomes easy.
As described above, since the vertical connecting member 10 indicates verticality, if the support column 2 is tilted with reference to this instruction, the carport A can be easily and surely constructed.

The present invention targets a roof structure in which the roof is supported by columns, and the objects include a garage (carport), a bicycle parking lot for storing bicycles (cycle port), and a corridor installed in a walking place for people. Including, but not limited to.
Further, in the illustrated embodiment, the roof 1 is cantilevered and supported by the columns 2, but the application target of the present invention is not limited to the cantilevered roof. In short, any object is included in the present invention as long as the columns of the roof structure have a sloping basic structure.
