Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for constructing a folded plate building, particularly a folded plate building whose purlin or frame is made of H steel, and a mounting bracket suitable for use in the method for constructing the folded plate building. It is related to.

Folded plate buildings, especially those with H steel as the main building and frame, generally consist of 25 H steels, as illustrated in Figures 1 to 6, which show the construction method of conventional folded plate buildings. Connecting plates 20, 21 and 22 are all bolted to the ends of steel 1 and 1.

The main building and frame are constructed by fixing the nut to the bolt and connecting the two H steels 1 and 1. That is, H steel 1
Upper flange 10 (flange on the side where the folded plate material 4 is attached)
The upper and lower surfaces of the upper and lower 7 flange 11 are made of steel with a width of H.
A first connecting plate 20 with a width slightly wider than the width of the langes 10 and 11, and upper and lower flanges 10 and 1 of the H steel 1 with a width on the lower surface of the upper 7 langes 10 and the upper surface of the lower flange 11 of the H steel 1.
1. The second connecting plate 21 is slightly smaller than 1/2 of the width of 1.
wo, furthermore, a vertically long third connecting plate 2 is attached to the vertical plate part 12 of the H steel 1.
Fix 2 with bolts and nuts 6, respectively, and tighten the two H
It connects steel 1 and 1. As a result, the connecting plates 20, 21, 22, bolts, and nuts 6 protrude from the connecting portion of the H steel 1. Therefore, when a mounting bracket is directly fixed to the upper surface of the upper flange 10 of the H steel 1 (the surface on which the folded plate material 4 is attached), this mounting bracket is attached to the connecting plate 20 or bolts at the connecting portion of the H steel 1.

The nut 3 is deformed by riding on the protrusion, and as a result, it is impossible to attach the folded plate material 4 to the deformed mounting bracket, so it is necessary to avoid the connecting portion of the H steel 1.

Therefore, the conventional construction method for folded plate buildings is as shown in Figs. 1 to 6. Fix it with bolts, nuts, etc., and cut out the part of the bracket a that corresponds to the connection part of the H steel 1 with a gas burner, or as shown in the figure, connect the H steel 1. First, the bridge plate was fixed between the connecting part of the H steel 1 and the connecting part of the H steel 1, and then the span plate was fixed between the bracket a and the connecting part of the H steel 1.
Avoid joints. In the above manner, the bracket ai is fixed to the upper surface of the upper 7 flange 10 of the H steel 1 while being cut out, and the bracket bracket a and the gangplank bi are fixed, and then
Fix the mounting bracket C to the bracket a or the bracket a and the gangboard by welding, bolts, nuts, etc., and attach the folded plate material 4 such as folded plate roofing material or folded plate wall material to the mounting bracket C with bolts. In this way, folded plate buildings are constructed by attaching the plates to nuts or scrolls.

However, in the conventional construction method for folded plate buildings, in order to avoid protrusions of the connecting plate 20, bolts, and nuts B at the connection part of the H steel 1, the H steel 1 is fixed to the receiving metal fitting AKH steel 1, and the receiving metal fitting AOH steel 1 is The part that corresponds to the connecting part is cut out, or the bracket a and the spanning plate are fixed to the H steel 1. Therefore, it is necessary to fix the bracket a and the spanboard and cut out the bracket a, which requires a large number of work steps and poor construction efficiency. There is a problem in that it is necessary and is not useful for resource conservation.

Therefore, as shown in Fig. 4, the H steel 1' as a secondary beam is slightly raised and is perpendicular to the construction direction of the H steel 1 as the main beam. A construction method has been proposed in which a mounting bracket is fixed on the top surface to avoid the connection of the H steel 1 as the main beam.

However, in this construction method, the H steel 1' as the main beam and the H steel 1' as the secondary beam which are orthogonal to the main beam are slightly raised, so the strength is weakened. In other words, the H steel 1 has a force applied vertically to the upper and lower flanges 10.11 (a force applied perpendicularly).
However, it is weak against the force applied to the left and right sides of the vertical 7 lunges 10.11 (force applied horizontally). For this reason, if the H steel 1' as the secondary beam is slightly raised relative to the H steel 1 as the main beam, then the H steel 1 as the main beam and the H steel 1' as the secondary beam are Since horizontal force is applied, the strength deteriorates, making it undesirable for use as a folded plate building with a vibration-resistant structure.

The present invention aims to provide a construction method for a folded plate building that solves the above-mentioned problems, and a mounting fitting suitable for use in the construction method.

A first aspect of the present invention is to fix two connecting plates to the mounting surface of a folded plate material of H steel with a gap in the longitudinal direction of the H steel, and to connect the folded plate material mounting surface of the H steel and the two connecting plates. A second aspect of the present invention is characterized in that a mounting bracket is directly fixed to the mounting surface of the H steel, and a girder member is attached to the mounting bracket. It includes a fixing part and a mounting part for attaching the folded plate material, and the fixing part t
The mounting surface of the H steel plate is fixed, and the height is such that when the folded plate is attached to the mounting part, the folded plate does not hit the connecting part 5 of the H steel.

Hereinafter, an example of the method for constructing a folded plate building according to the present invention and six examples of mounting brackets used in the method for constructing a folded plate building according to the present invention will be described with reference to FIGS. 5 to 21. and explain.

5 to 9 show a first embodiment of the mounting bracket of the present invention, FIG. 5 is a front view, and FIG. 6 shows a method of constructing a folded plate building using the mounting bracket of the present invention. The schematic diagrams, Figures 7 and 8 are the ■-■ line arrow view and ■ in Figure 6.
The arrow view and FIG. 9 are partial cross-sectional views of the construction state.

The mounting bracket 5 of the present invention in this embodiment has a so-called three-mounted structure, including a top plate portion 50 having a slight horizontal center as a mounting portion, and a top plate portion 500 extending obliquely downward from both sides of the top plate portion 500. It consists of a side plate part 51, a vertical plate part 52 provided by hanging the end of the side plate part 51, and a bottom plate part 56 as a fixing part provided by horizontally bending the vertical plate part 52.

The height between the top plate part 50 of the mounting part and the bottom plate part 56 of the fixing part is fixed to the whole H steel 1 of the bottom plate part 56, and the top plate part 50
When the folded plate material 4 is fully installed, the folded plate material 4 should not become a connecting plate or port 3 of the connecting part of the H steel 1. That is,
The height of the mounting bracket 5 of the present invention is the height of the conventional mounting bracket C shown in FIGS. 1 to 6 plus the height of the receiving bracket a, and The hanging plate part 52 is lowered by the height of the receiving metal fitting a.

In the figure, 26 is a rectangular fourth connecting plate, the width of which is slightly smaller than half of the difference obtained by subtracting the entire width of the mounting bracket 5 from the width of the upper flange 10 of the H steel 1. It is something.

Next, a construction example of a method for constructing a folded plate building of the present invention using the mounting bracket 5 of the first embodiment of the present invention described above will be described.

First, connect the connecting plates 20, 21° 22 at the ends of the two H steels 1, 1.
, 23 e-bolt nuts 3, and the two H steels 1, 1 are fully connected to construct a purlin or frame.

That is, on the upper surface of the upper seven flange 10 of the H steel 1,
The two fourth connecting plates 26 are fixed at full intervals in the longitudinal direction of the H steel 1, and the first connecting plate 20 gold is fixed on the lower surface of the lower 7 flange 11 of the H steel 1. The second connecting plate 2
1 is fixed, and in the vertical plate portion 12 of the H steel 1, the third connecting plates 22 are respectively fixed.

Next, the bottom plate part 53 as a fixing part of the mounting bracket 5 of the present invention
'k, the upper surface of the upper 7 flange 10 of the H steel 1 and the 4th
It is fixed between the connecting plates 23 and 23 by welding or bolts and nuts.

Next, the top plate part 50 and side plate part 51 of the mounting bracket 5 are attached.
The folded plate material 4 is placed on the plate, and the folded plate material 4 is attached to the mounting bracket 5 by windings, hangers, bolts, nuts, welding, etc. as shown in the figure. Thereafter, by repeating the above-mentioned operations, it is possible to raise the roof and construct the walls, thereby constructing the folded plate building.

At this time, the construction method of the folded plate building of the present invention is as follows: H steel 1
Fix the mounting bracket 5 directly to the mounting bracket 5, and attach the folded plate material 4 to the mounting bracket 5.
Since it is a type of installation, there is no need for a receiving metal fitting a or a spanning plate to be interposed between the H steel 1 and the mounting metal C, unlike in the conventional construction method of folded plate buildings. Therefore, it is possible to omit the work of welding the receiving metal fitting a and the spanning plate or cutting out the receiving metal fitting a, thereby improving work efficiency. Moreover, since members such as the receiving fitting a and the spanning board are not required, it is useful for saving materials and resources.

Furthermore, since there is no need to slightly lift and fix the H steel 1' as the secondary beam relative to the H steel 1 as the main beam, the specified strength can be obtained without deterioration of the strength, and therefore the vibration-resistant structure can be folded. It can also serve as a sufficient anti-vibration function as a board building.

Further, in the mounting bracket of the present invention in this embodiment, the height from the top plate part 50 of the mounting part to the bottom plate part 53 of the fixed part is set to 56'? When fixed to the H steel 1 and attached the folded plate material 4 to the top plate part 50 of the mounting part, the height was set to such an extent that the folded plate material 4 does not hit the connecting plate 26 or bolt nut 3 of the connecting part of the H steel 1. Therefore, when the folded plate material 4 is completely attached to the mounting bracket 5, the folded plate material 4 will not be lifted up by the connecting portion of the H steel 1.

Moreover, since this mounting bracket 5 is bent horizontally from the vertical plate part 52 to form a bottom plate part 53 as a fixing part, the fixing area of the bottom plate part 56 to the H steel 1 is wide, and therefore, the fixing area for the H steel 1 is wide. 1
Easy to fix. Furthermore, the mounting bracket 5 is attached to the side plate portion 5.
1 is made to hang down to form a vertical plate part 52, and the tip of the vertical plate part 52 is bent horizontally to form a bottom plate part 53. Since the lower part of the mounting bracket 5 forms a mouth shape, It also has sufficient strength.

FIG. 10 and FIG. 11 are a front view and a partially sectional view showing a second embodiment of the mounting fitting of the present invention in an installed state.

The mounting bracket 6 of the present invention in this embodiment has a so-called three-pronged structure, including a top plate portion 60 with a slight horizontal center as a mounting portion, and a top plate portion 60 that extends obliquely downward from both sides of the top plate portion 60. It consists of a side plate part 61 and a fixing part 63 that corresponds to the root of the side plate part 61 and another side plate part 61. In the mounting bracket 6 of this embodiment, the side plate part 61 and the fixed part 63 are fixed to the H steel 1, and when the folded plate material 4 is attached to the top plate part 60 of the mounting part, the folded plate material 4 is connected to the Hml connecting part. The length is such that it does not touch the
Since it extends diagonally downward, the same effect as the mounting bracket 5 of the first embodiment described above can be obtained, and it is easy to process.

FIG. 4 is a schematic diagram of a folded plate building using the mounting bracket of the present invention, and FIG. 15 is a view taken in the direction of the ■ arrow in FIG. 14.

The mounting bracket 7 of the present invention in this embodiment is a mounting bracket used for the H steel 1'' having the narrow width of the upper and lower 7 langes 10'' and 11'', and its structure is the same as that of the first mounting bracket 5 described above. A top plate part 70 as a mounting part, a side plate part 71, a vertical plate part 72, and a bottom plate part 73 as a fixing part,
The width of the vertical plate part 72 and the bottom plate part 76 are fixed to the upper surface of the H steel 1 "upper flange 10" of the intermediate plate.
The width between the connecting plates 26 and 23 is slightly smaller.

The mounting bracket 7 of this embodiment has the same effect as the mounting bracket 5 of the first embodiment described above, and also has the H steel 1"
suitable for use. That is, in the mounting bracket 7 of this embodiment, since the widths of the vertical plate part 72 and the bottom plate part 73 are narrowed, the entire width of the bottom plate part 73 is narrower than the upper 7 langes 10 of the H steel 1''.
"Even if it is fixed between the two fourth connecting plates 23 and 23 fixed on the top surface, the side plate part 71 of the mounting bracket 75
There is no possibility that the mounting bracket 7 will be deformed and the folded plate material 4 will not be able to be attached to the bolt/nut 3 or the like.

FIG. 16 is a front view showing a fourth embodiment of the mounting fitting of the present invention.

The mounting bracket 7' of this embodiment is provided with a reinforcing plate having a shape equivalent to the width of the vertical plate part 72 and the bottom plate part 73 of the third mounting bracket 7 (on the inside surface side). 74 is fixed by welding or the like. As a result, the vertical plate portion 72
Even if the width of the bottom plate portion 73 is made narrower, there is no risk of weakening the strength.

17 to 19 show all the fifth embodiment of the mounting bracket of the present invention, FIG. 17 is a front view, FIG. 18 is a side view, and FIG.
FIG. 9 is a perspective view of the fixing part.

The mounting bracket 8 of the present invention in this embodiment is the above-mentioned sixth
Similar to the mounting bracket 7 of the embodiment, the upper and lower flanges 10'',
This is a mounting bracket used for H steel 1" which has a narrow width of 11", and its structure is similar to the above-mentioned second mounting bracket 6, with a top plate part 80 as a mounting part, a side plate part 81, and a fixing part. The width of the lower part of the side plate part 81 is made narrower than the part 83, and a reinforcing plate 84 is fixed to the upper surface of the side plate part 81 sandwiched therebetween, and has the same effect as the above-mentioned mounting bracket. can be played.

FIGS. 20 and 21 are a plan view and a perspective view of a fixing part showing a sixth embodiment of the mounting fitting of the present invention.

The mounting bracket 8' of this embodiment is the fifth mounting bracket 8 described above.
In this case, the side plate portion 81 has corners cut from the wide portion to the narrow portion, which has an excellent design and has the advantage of being easy to handle since there are no corners.

As is clear from the above examples, the method for constructing a folded plate building of the present invention is to directly fix the mounting bracket between two connecting plates at the connecting part of the H steel and to the mounting surface of the H steel, and Since the folded plate material is attached to the metal fittings, the conventional folding method is to completely fix the bracket and the span plate to the H steel, fix the mounting bracket to the bracket or the span plate, and then attach the folded plate material to the mounting bracket. Compared to the construction method for board buildings, there is no need to completely fix the metal fittings and gangplank, or to cut out the metal fittings, thereby improving construction efficiency. Furthermore, since there is no need for a metal holder or a spanning board, it is preferable from the viewpoint of saving materials and resources.

In addition, since there is no need to build a purlin or frame by slightly lifting the H steel as a secondary beam relative to the H steel as the main beam, it is not necessary for the protrusion of the H steel connection to escape, so the strength is improved. There is no problem with
Therefore, all buildings made of folded plates can be constructed as vibration-resistant dual-speed structures.

In addition, the mounting bracket used in the construction method of the folded plate building of the present invention has a fixed part and a mounting part.
It is fixed to the H steel and has a height that does not allow the folded plate material to hit the connecting part of the H steel when the folded plate material is attached to the mounting part. When a folded plate building is constructed by attaching folded plate materials, there is no risk that the folded plate materials will hit the joints of the H steel and be lifted up.

Note that, as a matter of course, the method for constructing a folded plate building according to the present invention and the mounting hardware used therein are not limited to the above-mentioned embodiments.
