TECHNICAL FIELD The present invention relates to a stop, a bicycle parking lot,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called shelter-type assembled roof that constitutes a roof such as a crossing corridor, an approach, or the like, and relates to a mounting structure of a horizontal member to a column for mounting a beam (arm) as a horizontal member to the column.

[0002]

2. Description of the Related Art Hitherto, as a structure for attaching a horizontal member of this type to a column, Japanese Patent Application Laid-Open No. 7-238623 has been applied to an assembled roof.
The one described in Japanese Patent Application Laid-Open Publication No. H10-260, 1993 is known. In this assembled roof, each arm (beam) that supports the roof main body is attached to the upper end of the column at the intermediate portion via a reinforcing joint material. For example, the reinforcement joining material shown in FIG. 14 of the publication is composed of a brace receiver attached to the upper end of a column and a brace reinforcement member attached to the brace receiver, and the brace receiver is fitted with the brace reinforcement member inside. An arm member receiving body having a cross section of “U” shape, a body supporting member into which the arm member receiving body is fitted, and a cap that supports the body supporting member and is attached to a support at a lower portion are integrally formed. I have.

[0003] In this case, the attachment of the arm to the support of the arm is carried out by first mounting the arm on the arm at the upper end of the support, then fitting and fixing the arm reinforcement to the arm support of the arm, and finally cutting the arm into two. Insert the crossed arms from both sides and fix them. In this state, in a state in which the arm member reinforcing member, the arm member receiving body and the main body supporting member are hidden inside the attached arm member,
Arms are attached to the columns.

[0004]

In such a structure for attaching the cross member to the column, each arm cut into two pieces is supported by the column in a cantilever manner. Even if it does, there was a problem that the support strength of the arm tree was reduced.
Moreover, because the butting parts of the arms are exposed to the outside,
It is not preferable in terms of design.

[0005] It is an object of the present invention to provide a structure for mounting a horizontal member to a column, which can increase the supporting strength of the horizontal member without deteriorating the design of the mounting portion.

[0006]

According to the present invention, there is provided a structure for mounting a horizontal member to a column, the horizontal member receiving a load at both outer ends being provided at an intermediate portion thereof at the upper end of the column. A mounting structure for a column, wherein a column and a lateral member are joined by a reinforcing joining material having a column engaging portion that engages with the column and a lateral member engaging portion that engages with the lateral member. Wherein both end portions of the lateral member engaging portion extend to the portions receiving the load of both outer ends of the lateral member, respectively.

[0007] According to this configuration, the horizontal member receiving the load on both outer ends is supported by the horizontal member engaging portion of the reinforcing joint material, and the horizontal member engaging portion is supported via the column engaging portion. Supported by columns. In this case, since the both ends of the horizontal member engaging portion extend to the portions receiving the load of the horizontal member, respectively, the horizontal member receives the load applied by the load of the horizontal member, and further receives the load. Is not received by the horizontal member engaging portion at the position, but is directly received by the horizontal member engaging portion. Therefore, even if the supporting strength of the horizontal member is low, it is possible to appropriately support the load applied to the horizontal member, and to give the horizontal member priority to the design function.

In this case, the horizontal member has a horizontal member main body formed in a substantially inverted “U” -shaped cross section, and the horizontal member engaging portion includes:
It is preferable to be mounted inside the horizontal member main body.

According to this structure, the horizontal member engaging portion can be hidden by the horizontal member main body without impairing the supporting strength of the horizontal member engaging portion, and the horizontal member and the horizontal member engaging portion can be hidden. The parts can be easily attached to each other. Also, when installing this,
It is not necessary to cut the horizontal member into two pieces as in the conventional case, the supporting strength of the horizontal member itself can be utilized, and the design is also neat.

[0010] In this case, the lower end of the horizontal member is
It is preferable that a cap member that covers the horizontal member engaging portion be hidden inside the horizontal member main body.

According to this configuration, the cap member allows
The horizontal member engaging portion can be completely hidden inside the horizontal member main body, and the design of the horizontal member can be further improved.

In these cases, a column reinforcing member is inserted into the column from below, and the column engaging portion is inserted into the column from above so as to overlap with the column reinforcing member. It is preferable that the reinforcing member and the strut engaging portion are fixedly fastened to the strut at a mutually overlapping portion.

According to this structure, the column reinforcing member for reinforcing the column and the column engaging portion of the reinforcing joint material are overlapped inside the column, and are fixed together to the column at this portion. The strength of the support of the horizontal member by the column can be further increased, and the joining strength between the horizontal member and the column can be increased. For this reason, sufficient strength can be given to an external force that tries to separate the horizontal member from the column.

In these cases, a bracket for receiving the load is attached to a portion of each of the outer ends of the horizontal member which receives the load, and the horizontal member engaging portion and the bracket are sandwiched between the horizontal members. It is preferable that they are fixedly fastened to the horizontal member.

According to this configuration, the load applied to the horizontal member can be stably supported in a wide area by the bracket. Also, since the cross member engaging portion and the bracket are fixedly fastened to the cross member with the cross member interposed therebetween, even if an external force other than a load from above is applied to the bracket, the cross member is fixed to the cross member. Can be fully supported.

After the bracket 34 and the back plate 25 are aligned, the fixing bolt 36 is inserted through the bracket 34 to make the back plate 2
The front and rear spar 5a, 5b are fixed to the crosspiece 3 by screwing into 5.

The reinforcing joining material 9 described above is accommodated inside the arm body 31, and the arm body 31 and the bracket 34 are accommodated therein.
The reinforcing joint member 9 is integrally fastened to the female screw plate 37 provided inside the reinforcing joint member 9 by screwing the mounting bolt 35 described above. That is, although the details will be described later, the reinforcing joint material 9 has an end portion at each of the front and rear spar 5
The arm members 31, the bracket 34, and the reinforcing joining material 9 are integrated to support the front and rear girders 5 a, 5 b, and thus the roof main body 4. Therefore, the roof main body 4 can be firmly supported, and the structure has a structure that can sufficiently withstand the “flagging” caused by the wind acting on the roof main body 4.

The cap member 33 attached to the lower end of the arm main body 31 is made of, for example, aluminum or resin, and is attached to the lower end of the arm main body 31 from below so as not to come off. In this case, the cap member 33 may be mounted in such a manner as to be pushed in, or may be mounted in such a manner that the cap member 33 is slid from the edge of the forehead in addition to screwing. The lower surface of the cap member 33 is disposed flush with the lower surfaces of the first and second gutter portions 32a and 32b,
The reinforcing member 9 is hidden by the cap member 33 inside the arm body 31. Thereby, the arm 3 is finished in a neat appearance design. Since the cap member 33 does not exist at the joint portion of the column 2, the cap member 33 is configured by two members before and after.

Are symmetrical with respect to the arm body 31 and the arm body 31
And are formed integrally. The first and second gutter sections 32a,
Reference numeral 32b extends sideways and upward from the lower end of the crosspiece main body 31, and the upper end is open. In this case, the first and second gutter sections 32a, 32b are respectively provided with front and rear girder 5a, 5b.
This is a water guiding gutter for guiding rainwater drainage flowing down from b to the support column 2 and is not a gutter for collecting water. However, since the upper end is open, the inside can be easily cleaned. Further, a drain port 38 for guiding rainwater drainage to the column 2 is formed at a portion of the first and second horizontal gutter portions 32a and 32b joined to the column 2, and any of the horizontal gutter portions 32a and 32b is formed.
b can be used, but a drain gutter 38 is provided on the lower surface of the actually used gutter (first gutter 32a in the embodiment).
A short pipe 39 for the arm is connected to the armature.
The lower end of the short pipe 39 for the crosspiece is connected to a first downspout section 4 described later.
The rainwater drainage is directed to the column 2 through the drainage port 38 and the short pipe 39 for the crosspiece.

At the position of the support 2 shown by the solid line in FIG. 2, the drain port 38 of the arm 3 is located at an intermediate position in the longitudinal direction of the arm 3, so that the arm 3 does not have a left hand or a right hand. , At the position of the strut 2 indicated by the imaginary line,
Right-handedness occurs (see FIG. 1). Therefore, contrary to the present embodiment, when rainwater drainage is received by the right arm 3 of FIG. 1, the rainwater drainage is received (used) by the second cross gutter 32b. That is, since the front and rear positions of the column 2 (the position of the drain port 38) are regulated, the right arm 3 is in the same installation form as the left arm 3 is translated.

As shown in FIGS. 3, 4 and 5, the column 2 is composed of a hollow column main body 41 and a pair of covers 42, 42 mounted on the left and right sides of the column main body 41. , And have a substantially circular cross section having a band-shaped flat surface on all sides.

The second downspout 45b communicating with 32b is formed respectively. That is, the rainwater drainage flowing down from the first downspout 32a is guided to the ground surface through the first downspout 45a. However, in practice, a drainage pipe is connected to the lower end of the first downspout part 45a, and rainwater drainage is guided to the drainage basin via the drainage pipe.

The reinforcing joining material 9 is composed of a crosspiece engaging portion 13 that engages with a crosspiece and a post engaging portion 14 that engages with the post 2, and these are welded in a "T" shape. The crosspiece engaging portion 13 is formed in the shape of a square pipe having a rectangular cross section, and both outer ends thereof extend to the mounting positions of the front and rear beams 5a, 5b. That is, the crosspiece engaging portion 13 directly supports the front and rear beams 5a, 5b, and thus the roof main body 4. On the other hand, the strut engaging portion 14 is configured by facing a pair of engaging portion pieces 14a, 14a formed in a U-shaped cross section, and is welded thereto so as to sandwich the crosspiece engaging portion 13. . Then, in a state where the column engaging portion 14 is attached to the column 2, the column engaging portion 14 is inserted inside the column reinforcing member 10.

The column reinforcing member 10 is formed in the shape of a square pipe having a rectangular cross section. The lower end of the column reinforcing member 10 is embedded in the concrete foundation 11, and the upper end extends to the same position as the upper end of the column 2. That is, the column reinforcing member 10 functions as a core material of the column 2. Further, the upper end of the column reinforcing member 10 and the column engaging portion 14 of the reinforcing joining material 9 overlap inside the column 2, and in this state, the column 2 is fixed by the fixing screw 43.
Has been tightened together.

As described above, according to the present embodiment, since the arm bar engaging portion 13 of the reinforcing joint member 9 extends to the mounting position of the front and rear beams 5a, 5b, the roof main body 4 is directly supported. The roof main body 4 can be firmly supported. Moreover, since the support | pillar engaging part 14 of the reinforcement joining material 9 and the support | pillar reinforcement member 10 are mutually fixed, the wind "Aori"
Is also strong. Moreover, arm 3
Is an assembly mode in which the reinforcing joint member 9 mounted on the support column 2 is mounted on the reinforcing joint material 9 and screwed, so that the assembly can be easily performed.
