Each mounting piece 1a of this mounting bracket 1 is attached to the front surface of each opposing end of the girders 4 and 5 which are joined to each other via bolts 6 and nuts (not shown).

However, since the end girder 5 is only cantilever-supported by the mounting piece 1a of the mounting bracket 1 attached to the support column 2 via bolts 6 and nuts, the vertical load exerted by wind pressure, snow accumulation, etc. It has disadvantages in terms of strength, such as being extremely weak and prone to twisting, etc., and the upper end of the pillar 2 is
Since it bulges out from the front, it has the disadvantage of being extremely unsightly in appearance.

The present invention has been made to solve the above-mentioned drawbacks, and provides a connection structure between a column, a middle girder, and an end girder, which has a good appearance and is excellent in strength.

The connection structure between the support, the middle girder, and the end girder in an assembly structure such as a bicycle hangar according to the present invention is such that the middle girder and the end girder facing each other along the left and right direction are connected at least in cross section with a front wall and an upper and lower wall. The two girders are configured in a U-shape, with their opposing ends overlapping each other by a predetermined amount, and an opening into which the upper end of the column can be inserted while the opposing end portions of both girders are overlapped. It is formed by cutting out opposite ends of the lower wall, through which the upper end of the column can be inserted into the overlapping part of both girders, and the cutout end of the opening can be brought close to or in contact with the side surface of the column. It is characterized in that both girders and the support are connected through appropriate fixing means.

Next, one embodiment will be described with reference to FIGS. 2 to 5. Note that this embodiment relates to an example in which the present invention is applied to a bicycle hangar, and below, only the structure on the front side of the hangar will be explained, and the structure on the rear side, which is opposite to the front and back and has the same structure, will be explained below. The explanation will be omitted.

That is, in the figure, reference numeral 11 is a hollow rectangular support formed by bending a predetermined number of metal plates erected at a predetermined interval in the left-right direction. The columns (not shown) are each connected to each other by a horizontal hollow square beam 13 attached via a mounting plate 12 to a portion near the upper end thereof. At the rear surface of the upper end of each support column 11, threaded portions 11a, 11a are formed by burring, nutsert, or the like.

Reference numeral 16 denotes a predetermined number of middle girders installed along the left-right direction between the upper ends of the adjacent columns 11, 11.
19, and is made of a sheet metal bent and formed into a U-shaped cross section, and rear walls 20, 21 are provided facing each other from the rear end edges of the upper and lower walls 18, 19.

The left and right ends of the lower wall 19 of each middle girder 16 are connected to the support columns 11
The two middle girders 16, 16 are cut out by an amount approximately equivalent to half of the width in the left and right direction of the front wall 17, 1.
7 and the upper walls 18, 18 are in contact with each other,
When joined, the opposing lower walls 19,1
An opening 22 is formed between the notched ends 19a and 19b of the support 9, into which the upper end of the support 11 can be inserted in a substantially fitted state. In addition, the rear wall 20, 2
The left and right ends of 1 are also cut out ends 19a, 19 of the lower wall 19
The cutout is made to match b in the vertical direction.

Further, in the middle portion of the upper wall 18 of each middle girder 16 in the left-right direction, there is an insertion hole 23 in the shape of an elongated rectangle that is positioned near the front wall 17 and extends in the left-right direction, and in the center of the insertion hole 23 in the left-right direction. A suitable number of insertion holes 24 for fixing devices are bored in the rear position directly opposite the upper wall 18. Insertion hole configuration notches 23a and 23b which form half of the insertion hole 23 and insertion hole configuration notches 2 which form half of the insertion hole 24, respectively, are positioned on the direction extension line.
4a and 24b are formed, and as described above, 2
When the two middle girders 16, 16 are joined,
Insertion hole configuration notches 23a and 23b joined to each other
And also with the insertion hole configuration notches 24a and 24b,
The same insertion holes and insertion holes as the insertion holes 23 and 24 at the center are formed. Incidentally, the upper wall 18 of the middle girder 16 is further provided with mounting holes 25a, 25b similar to the insertion holes 24, located in the lateral vicinity of the respective insertion hole configuration notches 24a, 24b formed at the left and right ends. The front wall 17
Each mounting piece 1 of the mounting bracket 14 is attached to the left and right ends of the mounting bracket 14.
Attachment holes 26, 26 are drilled corresponding to the attachment holes 27, 27 drilled in 4a.

The two middle girders 16, 16 configured in a bilaterally symmetrical shape in this manner are in a state where their opposing ends, that is, the opposing ends of the front walls 17, 17 and the upper walls 18, 18 are joined, and The upper end of the pillar 11,
The opening 22 formed between the notch ends 19a, 19b of the lower walls 19, 19 is located within the joint portion of the middle girders 16, 16, and in contact with the joint portion of the upper walls 18, 18, as described above. Each mounting piece 14a of the mounting bracket 14 attached to the upper end of the support column 11
, on the back surface of each front wall 17,
7 and the mounting holes 26, 27 of the mounting piece 14a with bolts 28 and nuts 29, thereby attaching it to the upper end of the support column 11.

Therefore, such a support 11 and a middle girder 16,
16, the upper end of the support column 11 and the mounting bracket 14 are located within the joint between the middle girders 16, 16, and are not exposed on the front side of the middle girders 16, 16. It looks extremely good in appearance.
Moreover, since the front surface of the column 11 is in contact with the rear surface of the front walls 17, 17, and the thickness of the front wall 17 is extremely small, the front surface of the column 11 and the middle girders 16, 1
It is substantially flush with the front surface of 6, and the appearance is even better.

Further, since the upper end of the support column 11 is located within the joint between the middle girders 16 and 16, and the mounting bracket 14, that is, each mounting piece 14a is attached to the rear surface of each front wall 17, the support support 11 and Compared to the case where the mounting bracket 14 is attached to the front side of the middle girder 16, it is strong against the vertical load acting on each middle girder 16, and the occurrence of twisting etc. can be prevented as much as possible, which is advantageous in terms of strength. Furthermore, as described above, if the upper end of the support column 11 is brought into contact with the joint portion of the upper walls 18, 18, and this is received and supported, the above-mentioned strength advantage becomes even more remarkable. Furthermore, the cutout end 1 of each lower wall 19
9a and 19b are brought into contact with or close to the side surface of the support 11, and each mounting piece 1 of the mounting bracket 14 is
4a also in contact with each upper wall 18, the strength becomes even more effective.

In addition, when installing the support columns 11 and the middle girders 16, 16, each mounting piece 14a of each mounting bracket 14 attached to the adjacent support supports 11, 11 should be
Since the left and right end portions of the upper wall 18 can be placed and supported, and the mounting bracket 14 functions as a tool for positioning and temporarily holding the middle girder 16, the above-mentioned mounting work can be carried out extremely easily. It's convenient to do.

Furthermore, as described above, if the middle girder 16 is configured in a symmetrical shape, it can be used as a common member in any of the multi-building type bicycle hangars with different frontage widths. It is also convenient when expanding or contracting the bicycle hangar because it can be done easily.

Reference numeral 30 is a member that supports the roof on the side end side of the pillar, and is the right end girder connected to the right end of the rightmost middle girder 16. This end girder 30 is connected to the front wall 31 and the top and bottom It is made of sheet metal and is bent and formed into a U-shaped cross section with walls 32 and 33, and further has rear walls 34 and 35 facing each other from the rear end edges of the upper and lower walls 32 and 33, The right end portion is closed with a side wall 36. Note that the lower surface portion on the right end side of the end girder 30 is formed in a slightly inclined shape, and the front wall 31 and the lower wall 3
3. Each left end side portion of the rear wall 35 is also formed accordingly.

The longitudinal width of the upper wall 32 is set to be slightly larger than the longitudinal width of the upper wall 18 of the middle girder 16, and the left end portion of the end girder 30 is connected to the right end portion of the middle girder 16, and the upper wall of the end girder 30 is The lower surface of the wall 32 is connected to the upper surface of the upper wall 18 of the middle girder 16, the rear surface of the former front wall 31 is connected to the front surface of the latter front wall 17, and the front surface of the former rear wall 34 is connected to the rear surface of the latter rear wall 20. While in contact with
Mounting hole 2 to be drilled on the right end side of the front wall 17 of the middle girder 16
6 can be inserted into the front wall 31 of the end beam 30 to a position slightly to the right of the left end thereof. Note that the vertical widths of the front wall 31 and the rear wall 34 of the end beam 30 are such that, in the above-described fitted state, each of the lower edges of the front wall 31 and the rear wall 34 is as wide as each of the front wall 17 and the rear wall 20 of the middle beam 16. The upper and lower widths of the rear wall 34 of the end beam 30 are also set so that the upper edge thereof coincides with the upper edge of the rear wall 21 of the middle beam 16.

Further, in the front wall 31 of the end beam 30, there are mounting holes 37, 37 that match the mounting holes 26, 26 when both the beams 16, 30 are fitted as described above.
The same hole is provided at a position spaced to the right from the mounting hole 37 by an amount corresponding to the left-right distance between the mounting holes 27, 27 of the left and right mounting pieces 14a, 14a of the mounting bracket 14. Mounting holes 37', 37' are bored.

In addition, the left end of the lower wall 33 of the end girder 30 is connected to both girders 1
6 and 30 are fitted together, an opening 38 similar to the opening 22 is formed between the lower wall 19 of the middle beam 16 and the notched end 19a. Note that the left end portion of the rear wall 35 of the end beam 30 is also cut out so as to be continuous with the cutout end 33a of the lower wall 33.

Also, on the upper wall 32 of the end girder 30, both girders 16, 3
0 is fitted, the upper wall 1 of the middle girder 16
The left half portions thereof are made to match with the insertion hole forming notch 23a and the insertion hole forming notch 24a formed in the hole 8, respectively. The same insertion holes 39 and 40 as the insertion holes 23 and 24 are provided, and the same insertion holes 41 are also provided near the right end.
and an insertion hole 42 are drilled therein, and an attachment hole 43 that matches the attachment hole 25a of the upper wall 18, and an identical attachment hole 44 in the attachment hole 43 at a symmetrical position with respect to the insertion hole 40. Each hole is drilled.

Then, the right end girder 30 configured in this way
and the rightmost middle girder 16 are connected via the same fixing means as in the case of the above-mentioned middle girders 16, 16, with their opposing end portions overlapping each other by a predetermined amount. be.

That is, both the girders 16 and 30 are fitted in the above-described state, and the notched ends 19a and 33 of both the lower walls 19 and 33 are
From the opening 38 formed between the middle girder 16 and the middle girder 16, each mounting piece 14a of the mounting bracket 14 attached to the strut 11 is inserted through the opening 38 formed between the middle girders 16 and 30. Attachment holes 37, 26,
27 or 37', 27 with bolts 28 and nuts 29, both girders
6 and 30 are connected with the upper end of the support column 11 interposed therebetween. Note that the left half of the upper end of the support column 11 is in contact with the upper wall 18 of the middle girder 16.

Therefore, in such a connection structure between the middle girder 16 and the end girder 30, even though the end girder 30 is installed in a cantilevered manner, both girders 16 and 30
Because they are not simply joined, but are connected by being fitted into each other by a predetermined amount, the middle girder 16 acts as a reinforcing member for the end girder 30, and the end girder 30 does not need to be provided with a special reinforcing member. It is strong against vertical loads acting on the 30 and can prevent twisting etc. as much as possible.
It is advantageous in terms of strength.

Moreover, this advantage is even more advantageous in terms of strength because the notched end 33a formed in the lower wall 33 of the end girder 30 is brought close to (or in contact with) the side surface of the support column 11 as shown in FIG. Become. That is,
When the notched end 33a is close to (or in contact with) the side surface of the support column 11, the end girder 3
Even if the end girder 30 tries to deform greatly, the deformation of the end girder 30 is restricted by the contact between the notch end 33a and the support column 11, and the vertical load acting on the end girder 30 is supported by the support column 11, so that one piece of the end girder 30 is The supporting strength and torsional strength can be greatly improved.

Note that this strength advantage is similar to the above-mentioned mounting structure between the support column 11 and the middle girders 16, 16.
This becomes even more noticeable by attaching the connecting portions 6 and 30 to the upper end of the support column 11 via the mounting bracket 14. The reason for this is exactly the same as in the mounting structure between the support column 11 and the middle beams 16, 16.

By the way, in the connection structure of both girders 16 and 30, the right half of the upper end of the support column 11 and the upper wall 32 of the end girder 30 do not contact each other, and there is a middle girder 1 between them.
There is a gap equal to the thickness of the upper wall 18 of the middle beam 16 (see FIG. 3), and there is also a gap between the mounting piece 14a of the mounting bracket 14 and the front wall 31 of the end beam 30. Although gaps will be created by the thickness of 17 (see FIG. 4), there is no possibility that the above advantages will be lost due to the existence of these gaps. That is, the distance between each of the ends is only the thickness of each wall of the middle girder 16 and is extremely small, and in the former case, the upper wall 32 of the end girder 30 is connected to the support column together with the upper wall 18 of the middle girder 16. Since it is received and supported by the left half of the upper end of the column 11, it does not affect the receiving and supporting effect of the support column 11 in any way, and the latter is supported by the tightening action of the bolt 28 and nut 29. Said〓
It is possible to eliminate the gap. Further, the above-mentioned gaps can be easily eliminated by inserting a spacer having the same thickness as each wall, for example, a spacer 45 as shown in FIG. 4, between the gaps.

In addition, the support column 11 is located within the overlapped portion of both girders 16 and 30.
Since the upper end of the upper end and the mounting bracket 14 are located, the appearance is extremely good, similar to the mounting structure between the support column 11 and the middle girders 16, 16.

Further, during assembly, since both the girders 16 and 30 are fitted together, the positioning and temporary holding of both the girders 16 and 30 can be easily performed, which is advantageous in terms of work.

In the above embodiment, the middle beam 16 was fitted into the end beam 30, but the opposite may be used.

Next, each upper wall 18 of the middle girder 16 and the end girder 30 attached to the upper end of the support column 11 as described above,
32, a large number of peaks 47a, 47a, .
A folded plate roof mounting structure in which folded plate roofs 47 made of sheet metal, which are arranged in a row at regular intervals in the left and right direction, are attached via roof holders 48 will be described.

That is, the roof bracket 48 has a trapezoidal and upright support wall 49 that can fit into the peak 47a of the folded plate roof 47, and a rectangular support wall 49 that projects horizontally from the upper end of the support wall 49 to the rear. The roof support piece 50 and the support wall 49

are formed respectively.

A tip bolt 53 of a predetermined length is fixedly held on the roof support piece 50 so as to project upward. The lower end of the tip bolt 53 is fixed to the roof support piece 50 by caulking, but it may also be fixed by welding or the like.

Further, a threaded portion 54 is formed in the mounting portion 52b of the mounting piece 52 by burring or nut-sert, and each support piece 51 is provided with an insertion hole 51a for a fixing device. . In addition, the notch 2 for configuring the insertion hole to which the middle girders 16, 16 are joined

The engagement portion 52a and the screwed portion 54 are made to substantially match the positional relationship in plan view in the insertion hole 23 (or the insertion hole forming notch 23 to be joined).
a, 23b, insertion holes 39, 41) of the end girder 30,
It has an elongated rectangular shape that allows a mounting piece 52 having a threaded portion 54 to be inserted therethrough. Note that the insertion holes 25a and 25b are provided only at the left and right ends of the middle girder 16,
Further, the insertion holes 43 and 44 are formed only at the left end portion of the end beam 30.

And each roof bracket 4 configured as above

a.23b, 39, 41, and bring each mounting portion 52b to the lower surface side of the upper wall 18, 32 of each girder 16, 30, and each pair of support pieces 51, 51.
are placed on the upper walls 18, 32 of each girder 16, 30, and then the bolts 56 are inserted into the screwed parts 54 of each mounting part 52b through the respective insertion holes 24, 24a, 24b, 40, 42. By screwing each digit 1
6, 30 are attached to the upper walls 18, 32. The engaging portion 52a of each mounting piece 52 is connected to each insertion hole 2.
3, 23a, 23b, 39, and 41 so that it is not accidentally rotated.

In addition, at the joints of the two girders 16, 16 or 16, 30, each pair of support pieces 51, 51 are
Each girder 16, 30 is fixed to the upper wall 18, 32 through each mounting hole 25a, 25b, 43, 44 with a bolt 57 and a nut 58, and both girders 16, 16 or 16, Further, the connection of the holes 30 is strengthened, and the notches 23a, 23b for forming the insertion holes and the notches 24a, 24b for forming the insertion holes are properly joined. In addition, at each joint location, each mounting portion 5
2b is located within the upper end opening of each post 11.

Further, each of the roof brackets 48 attached to the upper walls 18, 32 of each girder 16, 30 in this manner has the folded plate roof 47 with its mountain portion 47a attached to the supporting wall 49 and the roof bracket 50. It is mounted with the connecting portion 47b placed on the upper wall 18, 32 of each girder 16, 30. In this installation, as in the usual case, the folded plate roof 47 is artificially pressed or hammered to pass each tip bolt 53 through the folded plate roof 47.
This is done by screwing a nut 60 onto each of the holes 3 and 3 with a washer 59 interposed therebetween. In addition, 61 is a U-shaped gable, and this gable 61 has its lower wall connected to the end girder 3.
0, and its upper wall is attached to the roof bracket 48 at the end of the end girder 30 together with the folded plate roof 47. As shown in FIG. 2, the roof bracket 48 for attaching the gable 61 has a slightly notched end.

In such a folded plate roof mounting structure, the roof bracket 48 is not welded to the upper walls 18, 32 of the girders 16, 30, but is attached to one fixing device, that is, the bolt 56.
It can be easily installed by holding it, and since the engaging part 52a of the roof bracket 48 is engaged with the elongated rectangular insertion hole 23, 23a, 23b, 39, 41, there is no possibility of accidental rotation around the bolt 56. There is no risk of being moved. Further, the roof bracket 48 connects the pair of support pieces 51, 51 to the upper walls 18, 32 of the girders 16, 30.
Since it is placed on the table, there is no risk of it being accidentally tilted.

Therefore, the roof bracket 48 is connected to the beams 16, 30.
The folded plate roof 47 can be easily and stably attached to the upper walls 18, 32 with only one bolt 56, and therefore the folded plate roof 47 can be attached in an extremely stable state while increasing work efficiency. In addition, at the joints of girders 16, 16 or 16, 30,
Although the pair of supporting pieces 51, 51 of the roof bracket 48 are also attached to the girders 16, 30 with bolts 57 and nuts 58, this is not necessarily required. Further, the number of roof brackets 48 and the mounting locations are not limited to those in the embodiment described above, and can of course be arbitrarily determined depending on the shape of the folded plate roof 47 and the like.

Further, the shape of the support wall 49 of the roof support fitting 48 is also arbitrary, but as described above, the peak part 49 of the folded plate roof 47
If the shape is such that it can fit into a, both 47
Due to the fitting action of a and 49, the attachment state of the folded plate roof 47 to the roof bracket 48 is made more stable, and the roof bracket 48 also functions as a so-called side door. , is advantageous.

It goes without saying that the present invention can be suitably applied not only to bicycle hangars but also to prefabricated buildings such as garages.

As can be easily understood from the above explanation, the connection structure of the column, middle girder, and end girder of the present invention does not simply connect the middle girder and the end girder, but rather connects their opposing ends to each other. Since they are connected by being overlapped by a predetermined amount, the middle girder can function as a reinforcing member for the end girder against the vertical load acting on the cantilevered end girder. Moreover, since the notched end of the opening formed in the lower wall of the end girder is placed close to or in contact with the side surface of the support column, even if the end girder is significantly deformed due to a vertical load, the notch end and the side surface of the support column come into contact with each other. The deformation of the end girder is regulated, and the vertical load applied to the end girder can be sufficiently resisted. Therefore, due to the action of these middle girders as reinforcing members and the deformation control action of the end girders by the notched ends and columns, even if the end girders are in a cantilevered state, the vertical load can be handled without the need for any special reinforcing members. It is extremely strong in terms of strength, and can prevent twisting as much as possible.

In addition, according to the connection structure of the present invention, the upper end of the column is located within the overlapped part of the middle girder and the end girder, and both girders and the column are connected via appropriate fixing means. Just by increasing or decreasing the number of pillars as appropriate,
You can freely set the length of the assembled building.
