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.
Then, a rod-shaped fixture 2 with bolt parts 2b formed at the upper and lower ends is welded, and the bolt part 2b of the fixture 2 is inserted into the insertion hole 4 drilled in the girder 3. The roof bracket 1 is mounted on the upper wall of the girder 3 by screwing the nut 5, and the groove bolt portion 2a is passed through the folded plate roof 6, and the nut 7 is attached to the groove bolt portion 2a. Usually, the folded plate roof 6 is attached by screwing.

However, the roof bracket 1 is simply a single fixture 2 that connects the girder 3.
Because it is attached to the roof, it is easily rotated around the fixing device 2 unexpectedly, and this also causes the nuts 5 to loosen, making it difficult to keep the folded plate roof 6 in a stable state. There is.

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 unsuitable 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 6.

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 structure of 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, 11a are formed by burring, nutsert, or the like.

Reference numeral 14 is a sheet metal plate having a U-shaped portion that can fit on the left and right surfaces and the rear surface of the upper end of the support column 11, and a pair of left and right mounting pieces 14av and 14a that protrude from both ends of the U-shaped portion in the left-right direction. This mounting bracket 14 is used to attach bolts 15 and 15 to the threaded portion 11a of the support.

By screwing it onto the support 11a, the upper end of the support 11 has a
In this attached state, the left and right mounting pieces 14a*14a extend in the left-right direction flush with the front surface of the support column 11.

Further, 16 is 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
It is made of sheet metal and is bent into a U-shaped cross section and has a front wall 17 and upper and lower walls 18.19.
Rear walls 20 and 21 are arranged in a row from the rear end edge of 19 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 the width of the support column 11 in the left and right direction. When the pillars 1 are joined in a state where they are brought into contact with each other, the pillar 1
1 is formed into an opening 22 into which the upper end portion of the opening 22 can be inserted in a substantially fitted state.

Note that the left and right ends of the rear walls 20 and 21 are also cut out to match the cutout ends 19a and 19b of the lower wall 19 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 rear wall 20 and extending in the left-right direction, and a center portion of the insertion hole 23 in the left-right direction. A suitable number of insertion holes 24 for fixing devices are bored in the front position facing directly to the upper wall 18, and the left and right ends of the upper wall 18 are provided with holes 24 in the left and right directions of the insertion holes 23 and the insertion holes 24. Insertion hole configuration notches 23a and 23b and the insertion hole 2 are positioned on an extension line and form half of the insertion hole 23, respectively.
4, and when the two girders 16 and 16 are joined as described above, the insertion hole construction notches 23a, 23b and 24b, which are joined together, are formed. Notches 24a and 24b for through hole configuration
Thus, the same insertion hole and insertion hole as the insertion hole 23 and insertion hole 24 in the center are formed.

In addition, the earthen wall 18 of the girder 16 is further provided with mounting holes 25a, 25b, which are similar to the insertion holes 24, and are located in the lateral vicinity of the respective insertion hole configuration notches 24a, 24b formed at the left and right ends.
are drilled in the left and right ends of the front wall 17, and mounting holes 27 and 27 are drilled in each mounting piece 14a of the mounting bracket 14.
A corresponding mounting hole 26.26 is drilled.

The two beams 16.16 configured in a bilaterally symmetrical shape in this way are in a state where their opposite ends, that is, the opposite ends of the front wall 17.17 and the earth wall 18.18 are joined, and The upper end of 11 is connected to the cutout end 19a of the lower walls 19, 19.

Attach each mounting piece 14a of the mounting bracket 14 to the back or rear surface of each front wall 17.
Bolt 28 and nut 29 through the mounting holes 26 and 27 of a.
By attaching it to the upper end of the support column 11.

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 11 and the girders 16, 16, the left and right end portions of the upper wall 18 of the girder 16 are placed and supported using the mounting pieces 14a of the mounting brackets 14 attached to the adjacent support 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 performed extremely easily and conveniently.

a and the insertion holes 23, 23a and 23b, there is no risk of unexpected rotation around the fixture 53.

Furthermore, since the support piece 51 of the roof support fitting 48 is placed on the upper wall 18 of the girder 16, there is no risk of the roof support fitting 48 being tilted unexpectedly.

Therefore, the roof bracket 48 can be easily and stably attached to the earthen wall 18 of the girder 16 with only one fixing device 53, and from this, the folded plate roof 47 can be attached extremely stably while increasing work efficiency. It is carried out in a state of

Note that the number and attachment locations of the roof brackets 48 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.

Furthermore, the roof bracket 48 includes a support wall 49, a roof bracket 50,
The main body consisting of the support piece 51 and the attachment piece 52 are constructed separately, and the vertical distance between the support piece 51 and the attachment piece 52 can be changed, so that the earth wall of the girder to which it is to be attached can be changed. Even if there is a difference in the thickness of the roof bracket 48,
It is convenient because it can always be properly installed.

Note that the locking portion 52c of the mounting piece 52 functions to prevent the mounting piece 52 from falling off and to grip it during work, and its shape is not limited to the above embodiment.

The shape of the support wall 49 of the roof bracket 48 is also arbitrary, but if it is shaped so that it can fit into the peak 47a of the folded plate roof 47 as described above, the fitting action of both 47a and 49 will cause This is advantageous because the state in which the folded plate roof 47 is attached to the roof bracket 48 is made more stable, and the roof bracket 48 also functions as a so-called side door.

In the above embodiment, in order to insert the fixture 53 from above the roof support piece 50 of the roof support metal fitting 48, a hexagonal insertion hole 50a through which the operating portion 53c can be inserted is bored in the roof support piece 50. However, it is sufficient to simply make a circular hole in the roof support piece 50 to allow the upper end portion of the fixture 53 to be inserted therethrough.

In this case, the upper end portion of the fixture 53 is inserted through the circular hole from below.

Furthermore, it goes without saying that the shape of the operating section 53c is not limited to a hexagonal shape.

Furthermore, the fixing tool 53 does not have both a groove bolt portion 53a for attaching a folded plate roof and a bolt portion 53b for attaching a roof bracket, but is simply a regular bolt for attaching a roof bracket. In this case,
A tip bolt corresponding to the groove bolt portion 53a is fixed to the roof support piece 50 by caulking, welding, etc. in a state that it projects upward.

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 can be attached to the upper wall of the girder through the elongated engagement hole drilled in the support piece. The nut is inserted by inserting it into an insertion hole that has approximately the same shape as the engagement hole to be drilled, and then screwing one fixture from outside the girder onto the threaded part formed in the mounting part of the mounting piece. To extremely simply attach a roof bracket to the earthen wall of a girder while improving workability, without requiring any troublesome work such as bringing a bolt into an ellipse and screwing a bolt thereon, or welding work.

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 fixture, the engaging portion of the mounting piece is engaged with the engaging hole and the insertion hole, and the supporting piece is attached to the earth wall of the girder. Because it rests on top, the roof bracket is stably attached to the girder without it being accidentally rotated or tilted around the fixture.

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

Furthermore, since the mounting piece is made separate and the vertical distance between it and the support piece can be changed, the roof bracket can always be properly attached to girders of different thickness while still achieving the above effects. , its practical value is extremely high.
