Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a roofing plate attachment device, particularly a roofing plate attachment device for large buildings such as factories, warehouses, and gymnasiums.

BACKGROUND OF THE INVENTION The present applicant previously proposed an apparatus for attaching a roof plate made of a thick metal plate that also serves as a structure to the roof of a building (see Utility Model Application No. 59-192526).

Problems to be solved by the invention However, the previously proposed device used bolts and nuts to secure the hangers to the mounting brackets, making the work of installing the roof panels relatively time-consuming.
There was a problem with poor workability. In addition, when repairing the roof shingles, it was necessary to remove bolts and nuts one by one, making the work of replacing the roof shingles extremely troublesome.

By the way, a folding plate mounting device for attaching a roof plate (folded plate) to a steel beam of a building without using bolts or nuts is already known (for example,
58-9421). The conventional folding plate mounting device is comprised of a tight frame (mounting metal fitting), a hanger attachment locking body fixed to the top of the tight frame by welding, and a hanger.

However, such conventional folding plate installation equipment requires three members: a tight frame, a suspension body for attaching a hanger, and a hanger in order to attach a roof plate to a steel beam of a building. Therefore, a large number of parts are used, and even though it is boltless, the locking body for attaching the hanger has to be fixed to the top of the support part of the tight frame by welding, which is time consuming and costly. However, there is also the problem that the shape of the connecting portion between the hanger attachment locking body and the hanger is complicated, making it difficult to manufacture the member.

The purpose of this invention is to solve the above-mentioned problems of the conventional technology, to reduce the use of bolts and nuts as much as possible, and to reduce the number of parts used and welding work when attaching roof panels to the roof of a building.

In this specification, top, bottom, right and left are based on FIG. 3, and upper means the upper side of Figure 3, lower means the lower side of the same figure, left means the left side of the same figure, and right means the right side of the same figure. .

In Figs. 1 to 4, the roof plate attachment device according to this invention attaches a required number of long roof plates 3 made of thick metal plates that also serve as a structure, and a girder 2 of a building 1 at predetermined intervals. a fixed required number of mounting brackets 4;
A hanger 5 for fixing the roof plate 3 to the mounting fittings 4 is provided.

As shown in FIG. 3, the roof plate 3 has a flat valley part 6 in the middle part of its width, and an arcuate left corner part 9 which is provided on the left side of the valley part 6 and has an inverted L-shaped cross section at the upper edge. It is composed of a rising portion 7 and an arcuate right rising portion 8 which is provided on the right side and has a connecting portion 10 having an inverted U-shaped cross section at its upper edge. roof board 3
If the width is wide, a convex portion having an occluded circular cross section may be provided in the middle of the flat valley portion 6 for reinforcement.

As shown in detail in FIGS. 2 and 4, the mounting bracket 4 has an upward protrusion 11 in the shape of a cut-out circle that opens downward, and a cut-out circular engagement part that opens diagonally upward to the left when viewed from the front on the left side of the top. A mating recess 13 is provided, and strip-shaped base portions 12, 12 are provided at both ends of the occluded circular upper protrusion 11, extending in both left and right directions. The strip-shaped bases 12, 12 of the mounting bracket 4 are attached to the girder 2 of the building 1.
fixed by welding or by bolts and nuts.

The hanger 5 is attached to the truncated upward protrusion 11 of the mounting bracket 4.
an arcuate leg portion 14 along the left upper surface of the roof panel, and a vertical rising portion 16 which is interposed between the connection portions 9 and 10 of the adjacent roof panels 3 and 3 and has a folded edge portion 17 with a substantially rectangular cross section. At the midpoint of the length of the arcuate leg 14, there is a lower arc-shaped engagement convex portion 15 that is convex from the front and fits tightly into the occluded circular engagement recess 13 of the mounting bracket 4. It is provided in a protruding shape. The hanger 5 is made of a resilient material such as a stainless steel plate, and its engagement protrusion 15 is slightly larger than the occluded engagement recess 13 of the mounting bracket 4 before mating. It has been made into an eye.

In the above, the roof plate 3 is attached to the girder 2 of the building 1 in the following manner.

First, the hanger 5 is fixed to the mounting bracket 4 fixed to the required location of the girder 2 of the building 1 with one touch without using bolts or nuts.

That is, the arcuate leg portion 14 of the hanger 5 is aligned with the left upper surface of the truncated upper protrusion portion 11 of the mounting bracket 4, and the convex arcuate engagement recess 15 in the middle of this leg portion 14 is aligned with the upper left side of the upper protrusion portion 11 of the mounting bracket 4. Occluded circular engagement recess 1 of portion 11
Insert it into 3. At this time, the convex arc-shaped engagement convex portion 1
5 into the opening of the occluded circular engagement recess 13, and then push it in firmly. Then, against the elastic force of the stainless steel plate constituting the convex arc-shaped engagement convex portion 15, it is once compressed and enters the occluded circular engagement concave portion 13. The portion 15 tries to return to its original size due to the elastic force of the material, and the restoring force remains in the engagement convex portion 15, so that the engagement convex portion 15 is pushed back into the engagement concave portion 1.
It is firmly attached to the inner wall of 3.

Next, the arcuate right rising portion 8 of one of the mutually adjacent roof panels 3, 3 is fitted onto the left half of the occluded upward protruding portion 11 of the mounting bracket 4 with the hanger 5, and the upper edge The inverted L-shaped connection part 9 is placed under the vertical rising part 16 of the hanger 5, and its tip 9a is
is inserted into the inside of the folded edge 17, which has a substantially rectangular cross section.

Then, on the right half of the circular upper protrusion 11,
The other arcuate left rising portion 7 is fitted and covered, and the inverted U-shaped connecting portion 10 on the upper edge of this is fitted and covered over the vertical rising portion 16 of the hanger 5, and the hanging tip portion 10a of the connecting portion 10 is inserted. Fold it inward. This results in
The vertical rising part 16 of the hanger 5 is connected to the adjacent roof board 3,
3, and the arcuate leg 14 of the hanger 5 is connected to the truncated upward protrusion 11.
is sandwiched between the upper surface of the left half of the roof plate 3 and the arc-shaped right rising portion 8 of the roof plate 3, and the convex arc-shaped engagement convex portion 15 of the leg portion 14 is inserted into the occluded circular engagement recess 13 of the upwardly protruding portion 11. Since they fit tightly together, the adjacent roof panels 3, 3 can be securely attached to the girder 2 of the building 1 via the mounting brackets 4 with hangers 5.

Since the roof board 3 also serves as a structure, there is no field or ceiling provided on the top of the building 1 as in the past, and the lower surface of the roof board 3 is directly visible inside the building 1. Since the connecting portion of the adjacent roof panels 3, 3 has a circular cross section, that is, a so-called omega shape, it is strong against external pressure, can withstand wind pressure suction force, and can prevent vibration of the roof. In addition, since the connecting portion of the roof sheets 3 and 3 has an occluded circular cross section, the expansion and contraction in the width direction of the roof sheet 3 due to thermal expansion and contraction of the metal plates constituting the roof sheet 3 is controlled by the opening of the connecting portion. Sufficient absorption can be achieved by deforming the portion by making it narrower or wider.

In addition, since the opening formed in the length direction at the lower edge of the connecting portion of the roof panels 3 and 3 is open toward the inside of the building 1, the sound generated inside the building 1 is It penetrates inside the cylindrical connection part and reflects diffusely, making it extremely effective at absorbing sound.
Note that a soundproofing material may be attached to the inner surface of the roof shingle 3 to further increase the sound absorption effect, or a heat insulating material such as polyethylene foam, asbestos fiber, or glass fiber may be pasted to the inner surface of the roof shingle 3 to enhance the sound absorption effect. Insulation work that is integrated with the ceiling can be performed extremely easily.

Note that the mounting brackets 4 do not need to be separated one by one as described above; for example, as shown in FIG. A series of metal fittings in which protrusions 11 are continuously formed may also be used. In this case, it is not necessary to adjust the arrangement intervals of the upper protrusions 11 one by one, which is very convenient and further improves work efficiency. This mounting bracket 4 is fixed to a girder 2 on the roof of the building 1, and a hanger 5 is attached to each occluded upward protrusion 11.
The point that the button is stopped and used with one touch is the same as in the above embodiment.

The roof plate attachment device according to this invention is applied to the roofs of relatively large buildings such as factories, warehouses, and gymnasiums. In some cases, it can also be applied to the side walls of these buildings. That is, in this case,
The metal plates constituting the side walls are of the same structure as the roof plate 3 described above, and mounting fittings 4 and hangers 5 are fixed to the rim at predetermined intervals, and the metal plates constituting the side walls are attached to these metal fittings. should be installed vertically.

In addition, in the above, the engagement recess 13 of the mounting bracket 4 has an occluded circular shape when viewed from the front, whereas the engagement protrusion 15 of the hanger 5 has a convex arc shape when viewed from the front. , these have other shapes, for example, a groove shape with an engaging recess 13, whereas an engaging convex part 1 is provided.
It goes without saying that 5 may have a dovetail shape, and in short, any shape that can be locked by being fitted into each other is sufficient.

Effects of the invention As mentioned above, this invention consists of a required number of roof plates made of metal plates, mounting brackets fixed at predetermined intervals to the girders of the roof of the building, and a hanger attached to the top of the metal plates. In the roof shingle attachment device, each shingle has a flat valley in the middle of its width;
An arc-shaped left rising part is provided on the left side of this and has a connecting part with an inverted L-shaped cross section on the upper edge, and an arc-shaped right rising part is provided on the right side of this part and has a connecting part with an inverted U-shaped cross section on the upper edge. The mounting bracket has an upwardly protruding portion in the shape of a notch that opens downward, and an engagement recess is provided on the left side of the top of the fitting. A strip-shaped base extending to both sides is provided, and the hanger is interposed between the arc-shaped leg along the left upper surface of the missing circular upper protrusion of the mounting bracket and the connecting parts of adjacent roof plates, and a vertical rising portion having a rectangular folded edge, and an engaging protrusion that fits into the engaging recess of the mounting bracket at the intermediate portion of the length of the arcuate leg. is provided in a downwardly protruding shape, and the arc-shaped leg of the hanger is aligned with the left upper surface of the truncated upward protruding part of the mounting bracket, and the engaging convex part in the middle of this leg is aligned with the upper protruding part. The arcuate right rising portion of one of the mutually adjacent roof panels is fitted into the left half of the occluded upward protrusion of the mounting bracket with hanger, and the same The other arcuate left rising part is fitted into the right half of the circular upward protruding part, and the vertical rising part having the folded edge of the hanger is sandwiched between the connecting parts of adjacent roof plates. In addition, the arcuate leg of the hanger is sandwiched between the upper surface of the left half of the occluded upward projection and the arcuate right rising portion of the roof plate. Bolts and nuts or welding are used to fix metal fittings to girders on the roof of a building at predetermined intervals, but fixing the hangers to the mounting metal fittings is extremely easy and can be done by hand with just one touch. The bolt can be
No nuts or welds are required. Therefore, the use of bolts and nuts can be minimized.

In addition, when attaching the roof shingles to the roof of a building, only the mounting brackets and hangers are used, rather than the traditional hanger attachment locking bodies, which reduces the number of parts used and requires less welding work. Therefore, the roof sheets can be easily attached to the roof of the building with extremely good workability. Moreover, since the shape of the member is simple, it is easy to manufacture, and the strength of attaching the roof plate is very high.
