Description

[Detailed Description of the Invention] The present invention relates to a folded plate roof mounting structure for attaching a folded plate roof to the earthen wall of a girder via a roof holder in an assembled building such as a bicycle hangar or garage.

In the conventional folded plate roof mounting structure of this type, as shown in FIG.
A and bolt portions 2b formed at the upper and lower ends of the rod-shaped fixture 2 are welded together, and the bolt portion 2b of the fixture 2 is inserted into the insertion hole 4 drilled in the girder 3. Screw the nut 5 onto the roof bracket 1 and attach it to the upper wall of the girder 3 in a resting manner, and then attach the groove bolt portion 2a to the folded plate roof 6.
Normally, the folded plate roof 6 is attached by passing through the grooved bolt portion 2a and screwing a nut 7 onto the grooved bolt portion 2a.

However, the roof bracket 1 is simply a single fixture 2 that connects the girder 3.
Since the folded plate roof 6 is attached to the roof, it is easy to rotate around the fixing device 2 unexpectedly, and this also causes the nuts 5 to become loose. It has the disadvantage of being difficult.

Further, since the troublesome work of bringing the nut 5 into the girder 3 and screwing it onto the bolt portion 2b of the fixture 2 is required, work efficiency is also reduced.

In addition, in order to prevent the roof bracket 1 from rotating, the roof bracket 1 may be attached to the girder 3 using another fixing device in addition to the fixing device 2, or it may be directly welded to the girder 3. Although this has been done, the former method is extremely inappropriate in terms of work and number of parts, and the latter method is undesirable because girders and the like are painted, and the workability is also poor.

The present invention has been made in view of the above points, and provides a folded plate roof mounting structure that can stably attach a folded plate roof to a girder while improving workability.

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 in the following, only the structure of the front side of the hangar will be explained, and the rear side, which faces front and back and has the same structure as this, will be explained below. The explanation will be omitted.

That is, in the figure, 11 is a hollow rectangular pillar formed by bending a predetermined number of metal plates standing at a predetermined interval in the left-right direction. Each of the columns (not shown) is connected to each other by a horizontal hollow rectangular shaft 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, lla are formed by burring, nutsert, or the like.

This mounting bracket 14 is made by screwing the bolts 15.15 into the threaded parts 11a and lla of the pillar.
It is attached to the upper end of the column 11 so as to hold it, and in this attached state, the left and right mounting pieces 14a, 14
a extends in the left-right direction flush with the front surface of the support column 11.

Reference numeral 16 denotes a predetermined number of girders installed along the left-right direction between the upper ends of adjacent columns 11 and 11, and these girders 16 are folded into a U-shaped cross section with a front wall 17 and upper and lower walls 18 and 19. It is made of curved sheet metal, and the upper and lower walls 18, 1
Rear walls 20 and 21 are arranged in a row from the rear end edge of 9 in a facing manner.

The left and right ends of the lower wall 19 of each girder 16 are cut out by an amount approximately equivalent to half of the width in the left and right direction of the support column 11, so that the two girders 16, 16 are separated from the front wall 17, 17 and the upper wall 1B. , 18 in contact with each other, an opening 22 into which the upper end of the support column 11 can be inserted in a substantially fitted state between the notch ends 19a, 19a of the opposing lower walls 19, 19. is starting to form.

Note that the left and right ends of the rear walls 20 and 21 also correspond to the notch end 1 of the lower wall 19.
The notches are formed to match 9a and 19a in the vertical direction.

Further, in the middle portion of the upper wall 18 of each girder 16 in the left-right direction, there is an insertion hole 23 in the shape of an elongated rectangle located near the front wall 17 and extending in the left-right direction, and a center portion of the insertion hole 23 in the left-right direction. An appropriate number of fixing device insertion holes 24 are formed at the rear position directly opposite to the upper wall 18 , and holes 24 are provided at the left and right ends of the upper wall 18 on the left and right extension lines of the insertion holes 23 and 24 . Insertion hole forming notches 23a and 23b forming half of the insertion hole 23 and insertion hole forming notches 24a forming half of the insertion hole 24, respectively.

Therefore, in such a mounting structure between the column 11 and the girders 16, 16, the upper end of the column 11 and the mounting bracket 14
is located within the joint of the girders 16, 16, and the girder 16
．． Since it is not exposed on the front side of 16, it has a very good appearance.

Moreover, since the front surface of the column 11 is in contact with the rear surface of the front wall 17.17, and the thickness of the front wall 17 is extremely small, the front surface of the column 11 and the front surface of the girder 16.16 are close to the road surface. As a result, the appearance becomes even better.

Further, the upper end of the support column 11 is located within the joint portion of the girder 16.16, and the mounting bracket 14, that is, each mounting piece 14
a is attached to the rear surface of each front wall 17, it is stronger against the vertical load acting on each girder 16, and The occurrence of twisting, etc. can be prevented as much as possible, which is advantageous in terms of strength.

Moreover, as mentioned above, the upper end of the pillar 11 is connected to the earth wall 18°1.
If it is brought into contact with the joint portion of No. 8 and is received and supported, the above-mentioned advantage in strength becomes even more remarkable.

Furthermore, the notched ends 19a and 19b of each lower wall 19 are connected to the support 11.
If the mounting piece 14a of the mounting bracket 14 is brought into contact with or approximately in contact with the side surface of the earth wall 18, the strength will be further increased.

In addition, when attaching the support column 11 and the girders 16, 16, the right and left end portions of the upper wall 18 of the girder 16 are placed on each mounting piece 14a of the mounting bracket 14 attached to the adjacent support column 11.11. Since the mounting bracket 14 functions as a tool for positioning and temporarily holding the girder 16, the above-mentioned mounting work can be carried out extremely easily and conveniently.

Next, the earthen wall 18 of the girder 16 attached to the upper end of the support column 11 as described above has a large number of cross-sections extending in the front-rear direction.

Note that the supporting wall 49 has a reinforcing portion 49a;
A reinforcing portion 49b is formed at the joint portion between the support piece 51 and the support piece 51, respectively.

A groove 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 forming the insertion hole to which the girder 16.16 is connected
The positional relationship between the insertion holes formed by 4a and 24b and the insertion holes 25a and 25b located on the left and right sides of the insertion holes 25a and 25b is as follows: , 51a in plan view, and the insertion hole 23 of the girder 16 (or the insertion hole formed by the insertion hole configuration notches 23 a and 23 b to be joined) and the insertion hole 24 (or the notches 24a and 24b for forming the insertion hole) are made to substantially match the positional relationship in plan view between the engaging portion 52a and the screwed portion 54 in the roof bracket 48, The insertion hole 23 (or the insertion hole configuration notches 23a and 23b) has an elongated rectangular shape that allows the attachment piece 52 having the screwed portion 54 to be inserted therethrough.

Note that the insertion holes 25ay 25b are formed only at the left and right ends of the beam 16.

Each roof holder 48 configured as described above has each mounting piece 52 inserted through each of the insertion holes 23, 23a and 23b, and each mounting portion 52b is brought to the lower surface side of the upper wall 18 of the girder 16. At the same time, each pair of support pieces 51 and 51 are placed on the earthen wall 18 of the girder 16, and the bolts 5 are inserted into the screwed parts 54 of each mounting part 52b through the respective insertion holes 24, 24a and 24b.

Of course, the operation portion 63c is not limited to a hexagonal shape.

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, according to the folded plate roof mounting structure of the present invention, the mounting piece of the roof bracket is inserted into the elongated insertion hole drilled in the earthen wall of the girder. By simply screwing one fixture onto the threaded part formed in the mounting part of the mounting piece from outside, there is no need for troublesome work such as bringing the nut into an oval shape and threading it onto the bolt, or welding work. The roof bracket can be attached to the earthen wall of the girder very easily while improving workability without having to do anything.

This improvement in workability is remarkable when it is necessary to install a large number of roof brackets.

Moreover, even though it is mounted using only one fixing tool, the retaining portion of the mounting piece is engaged with the insertion hole, and the support piece is placed on the earthen wall of the girder. Because of this, the roof bracket can be stably attached to the girder without being accidentally rotated or tilted around the fixture.

Therefore, the folded plate roof can be stably attached to the girder while improving workability.
