Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a metal shingle,
More specifically, the present invention relates to a novel metal roofing plate that exhibits a sound insulating effect, a heat insulating effect, and a radiation shielding effect by effectively utilizing a lead plate of a used lead storage battery and a used aluminum can.

[0002]

2. Description of the Related Art Copper has been widely used as a building material since ancient times, because it has excellent durability and fire resistance, is lightweight, has excellent workability, and requires no maintenance after construction. ing. For example, most of the roofs of shrines, temples, and temples currently have copper roofs.

[0003] The reason why this copper is exalted as a building material is that, in addition to the above-mentioned properties of copper itself, when exposed to the air for a long period of time, a patina film naturally rusts on its surface,
This is because it serves as a protective film to enhance the corrosion resistance of the material, and at the same time presents a distinctive and beautiful appearance. Such a copper roof is constructed by sequentially engaging copper plates having engagement portions formed on four sides in the vertical and horizontal directions of the roof surface.

[0004]

The following problems have been pointed out when a copper plate is used as a roof plate for a general house. First, since copper has excellent thermal conductivity, the level of the outside air temperature directly affects the room temperature. That is, the heat insulating effect is poor in itself.

[0005] In the case of a copper-roofed roof, for example, during rainfall, the rain sound reverberates greatly into the room and turns into noise, which often causes mental distress to residents. That is, the sound insulation effect is not exhibited by itself. For this reason, when constructing a copper-roofed roof, it is necessary to interpose members exhibiting heat-insulating and sound-insulating effects, for example, various resin foam sheets, between the copper roof plate and the roof surface. Have been done.

[0006] The present inventor has conducted intensive studies in order to solve the above-mentioned problems that occur when a copper roof is installed in a general house. Focusing on the fact that lead has excellent sound insulation properties and corrosion resistance, and also has the ability to shield against radiation such as ultraviolet rays, electromagnetic waves, X-rays, etc. Roofing has good sound insulation effect, heat insulation effect,
In addition, he had the idea that radiation shielding effect would be exhibited.

In this case, the effective use of industrial waste is intended by selecting a lead plate of a used lead storage battery that is treated as industrial waste as a lead material. In addition, from the viewpoint of effective use of industrial waste, the combination of used aluminum can waste and copper plate is also taken into consideration at the same time, and the metal roofing plate of the present invention is developed by performing various prototypes. Reached.

That is, the metal roofing sheet of the present invention has at least one bulging portion formed by bulging a central portion of a metal sheet so as to have a polygonal shape in plan view, and at least one bulging portion of the metal sheet. One of the upper edge portion and the lower edge portion is provided with an upper engaging portion and a lower engaging portion formed by bending at least one downward in the other direction. Inside, a lead plate of a used lead-acid battery or shredder of a used aluminum can is fixed. In particular, a metal thin plate is a copper plate, and a shredded chip of a lead electrode plate or a used aluminum can is provided with a metal roof plate fixed to the back surface of the bulging portion with a mixture of lead ash and cement. You.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION One example of a metal shingle A1 of the present invention
Is shown in FIG. 1 as a perspective view, and is shown in FIG. 2 as a cross-sectional view along the line II-II. The roof slats A1 are laid on the roof surface by being engaged with each other by engagement portions described below. In the drawing, in the illustrated coordinate system, the Y direction is the vertical direction of the shingle, the X direction is the width direction of the shingle,
The direction indicates the surface direction of the shingle.

In the drawing, a metal sheet 1 having an appropriate shape and dimensions is shown.
Is formed with a bulged portion 2 having a polygonal shape (rectangle in the figure) in plan view by bulging a central portion thereof in the Z direction. Therefore, the rear surface side of the bulging portion 2 is a concave portion that opens downward. The metal sheet used here is not particularly limited, but a copper sheet is preferable.

As shown in FIG. 3, the bulging portion 2 is formed by pressing a central portion of the thin metal plate 1 having the four corners 1a cut out using a mold having a desired shape. The shape of the bulging portion 2 in plan view is not limited to a quadrangle as shown in the figure, and may be an appropriate polygon. However, it is considered that this roof plate A1 is assembled as described later. It is preferable that the shape be a quadrangle in terms of ease of assembly.

[0012] Then, the upper edge 3a located above the metal sheet 1 (Y-direction), in the Z direction (upward) along the locations a ₁ spaced from the edge 2a of the bulging portion 2 by a desired length The upper engaging portion 3 shown in FIG. 1 is formed by being folded in two,
Further, a lower edge portion 4 located below (-Y direction) the metal thin plate 1
a is folded in _two in the −Z direction (downward) along a point a ₂ separated by a desired length from the edge 2 b of the bulging portion 2 to form the lower engagement portion 4 shown in FIG. Have been.

[0013] Similarly, bent to folded in a Z direction (upward) at the point a ₃ spaced a right side edge portion 5a from the bulging portion of the edge 2c located in the right direction (X direction) of the sheet metal 1, Further, the left edge 6a located on the left side (−X direction) is connected to the edge 2
at the point a ₄ spaced from d by bending the folded in the -Z direction (downward), the right engaging portion 5 shown in FIG. 1, the left engagement portions 6 are formed.

When forming the notch portion 1a at this time, the metal sheet 1 is formed such that the notch lines in the X direction and the Y direction are both located outside the edge line of the bulging portion 2.
Four corners are cut out. Thus, between the upper engaging portion 3 and the lower engaging portion 4 and the bulge portion 2 edge of shingles A1 shown in FIG. 1, as shown in FIG. 3, the length y ₁ interval There is formed, also interval length x ₁ between the edge of the right engaging portion 5 and the left engagement section 6 and the bulge portion 2 is formed.

As shown in FIG. 2, a lead plate 7 of a used lead-acid battery is fixed to a concave portion on the rear surface side of the bulging portion 2 of the thin metal plate. By the way, the lead plate of a used lead storage battery is industrial waste mainly generated in the field of the automobile-related industry. This lead plate is usually subjected to the following regeneration treatment. That is, first, the lead storage battery to be disposed of is disassembled, its internal components are taken out, and the lead plates are sorted out. Next, the lead plate is put into a melting furnace and melted. Then, the molten lead is removed from the furnace and cooled, and a lead plate having a predetermined shape is manufactured again from the obtained lead ingot. In the melting process, lead ash adheres to the flue of the furnace. This lead ash is a fine powder of lead oxide and contains about 65 to 70% by weight of a lead component. Therefore, it is refined to take out the lead component and use it again as a raw material for a lead plate. The impurities in the lead ash are discarded as slag.

The roof plate of the present invention uses a lead plate obtained by dismantling a lead storage battery. Specifically, after the lead plate obtained by disassembly is washed with, for example, water, it is fixed as it is inside the bulging portion of the above-mentioned thin metal plate. The fixing agent used at this time may be any as long as it can bond and fix the lead electrode plate to the metal thin plate. For example, a material obtained by kneading the above-mentioned lead ash and cement with water is preferable. . This is because lead ash can be used effectively, and at the same time, the sound insulation effect, heat insulation effect, and radiation shielding effect can be further improved by lead ash.

The metal shingle A1 can be manufactured as follows. First, a lead ash and cement are kneaded with an appropriate amount of water to prepare a fixing agent having appropriate fluidity. Next, the fixing agent is poured into the concave portion formed by the bulging portion 2 shown in FIG. 4 with a desired thickness, and the above-described lead electrode plate is placed thereon. Since the lead plate is a plate having various mesh patterns such as a lattice shape, a tortoiseshell shape, and a grid shape, the above-mentioned fixing agent oozes out of the mesh pattern. The cement is solidified by drying the whole. As a result, as shown in FIG. 2, the fixing agent 8 is applied to the back surface 2 of the bulging portion 2 of the thin metal plate.
e, and at the same time, the lead plate 7 is secured by the fixing agent oozing out from the network pattern.

The mixing ratio of lead ash and cement at the time of preparing the fixing agent is not particularly limited. However, if the amount of cement is too small, the adhesive force between the fixing agent and the rear surface of the bulging portion or the lead electrode plate In some cases, the adhesion of the lead ash may be weakened and peeling of the lead plate may be caused, and even if there is too much cement, the fixing ability of the fixing agent to the lead plate is reduced. It is preferable that the mixing ratio of cement is 45 to 50% by weight.

After solidification of the fixing agent, the lead plate 7
It is preferable to adjust the height of the swelling portion 2 and the thickness of the poured adhesive 8 so that the lower surface 7a of the swelling portion and the opening surface of the back surface concave portion of the swelling portion 7 form substantially the same surface. Furthermore, the components (lead ash and cement) of the dried fixing agent adhere to the surface of the lead electrode plate after the fixing in a state where the powder is wiped, and the dust is easily generated. Therefore, in the case of the metal roof plate of the present invention, it is preferable that a lead electrode plate is fixed to the bulging portion, and then a plastic film or the like is attached to the surface of the lead electrode plate. At this time, it is preferable to use a film or a glass mat incorporated as an insulating material in a lead storage battery to be disposed of as a plastic fill in terms of effective use of waste.

With respect to the roof plate A1 shown in FIG. 1, as shown in FIG. 3, the metal sheet 1 is formed with notches 1a at its four corners, and each edge 3a, 4a, 5a, 6a is simply formed. Although the example in which the engaging portions 3, 4, 5, and 6 are folded in two is shown, the metal sheet 1 of the present invention is not limited to this, and the notches 1a are formed at the four corners. Instead, each edge may be simply bent to form each engaging portion. In this case, since the four corners of the metal sheet overlap with each other, there is a problem that it becomes slightly difficult to bend.

In the case of the roof shingle A1 shown in FIG.
Although one lead plate 7 is fixed to one metal sheet 1, the present invention is not limited to this. For example, as shown in FIG. (Four in FIG. 5) bulges 2 are formed, and each bulge 2
As shown in the above, a roof plate may be formed by fixing the lead plate 7.

In this case, the roof shingle is made up of four metal sheets.
Since the four lead plates are fixed, they are about four times wider than the roof plate A1 shown in FIG. 1, and the four roof plates A1 are already engaged. I have. Therefore, considering the engagement of the roof shingles, the amount of work required for the entire engagement is reduced, and the amount of work of the roofing by the worker is reduced. In addition, since the plurality of bulging portions 2 are formed by one press working, the productivity is increased and the cost can be reduced.

The roof plate A1 has a structure in which a lead plate of a used lead-acid battery is fixed to the inside of a bulge formed in the center of a thin metal plate using a fixing agent composed of lead ash and cement. First, it is a shingle that effectively uses waste wood. In addition, since lead is also a heat insulating material, the influence of the level of the outdoor temperature on the indoor temperature is reduced, and this contributes to energy saving for ensuring an appropriate indoor temperature. Furthermore, since the lead plate also exerts a sound insulating effect, it is possible to suppress a situation in which the rain sound echoes into the room at the time of rainfall and is turned into noise.
And even if the roof is exposed to various kinds of radiation, for example, strong ultraviolet rays, it can be shielded.

FIG. 6 is a sectional view showing another roof plate A2 of the present invention. In the case of the roof plate A2, used aluminum cans are used instead of the lead plates in the roof plate A1. Aluminum cans, which are often used for beer cans, are collected as recyclable waste after drinking beer, and most of them are shredded and washed, then press-molded to a predetermined size, melted, and reused. You.

In the case of the shingle A2 of the present invention, as shown in FIG.
Is poured, and the above-mentioned shredder 9 is placed in a layered state, and the whole is fixed with a fixing agent. This shingle A2
Does not have the ability to shield electromagnetic waves or the like unlike the roof shingle A1, but exhibits the sound insulation effect and the heat insulation effect. And since it is lightweight compared with the shingle A1, it is effective when used for a house where a lightweight roof is desired.

Next, a method of engaging a roof slat according to the present invention will be described for the case of a roof slat A1 using a lead plate. In the case of this roof plate A1, each of the upper, lower, left and right engaging portions has a structure in which each edge of the thin metal plate 1 is simply folded into two,
When the roof slat A1 is laid on the roof surface, the center of the slab bulges at a certain height.

In the metal roof plate A1 shown in FIG. 1, the upper engaging portion 3 and the lower engaging portion 4 are engaged with each other in the Y direction, and the right engaging portion 5 and the left engaging portion 6 are mutually engaged. Engage in the X direction,
Then, the respective engaging portions are pressed to be laid on the roof surface. FIG. 7 shows the state of engagement at that time for the case of the upper engaging portion 3 and the lower engaging portion 4.

The upper engaging portion 3 of the roof shingle A1 'already fixed on the roof surface 10 and the lower engaging portion 4 of the roof shingle A1 laid above (in the Y direction) as shown in the figure. Be engaged. Then, the overlapped portion is pressed in the -Z direction as shown by the arrow p in the figure, and the two roof plates A1 'and A1 are pressed.
In the vertical direction (Y direction). Also,
The engagement in the X direction is performed in the same manner.

[0029] Note that this roof plate A1, the case of A1 ', the length of the bulge portion of the edge 2a in the upper engaging portion 3 to the bent position a _1, and the edges of the bulge portion of the lower engaging portion 4 2b
Length from to the bending position a ₂ is, when engaged with the engaging portion, has a length that does not reach the edge 2a, 2b of the bulging portion in another shingle. In this manner, the roof shingle is successively engaged in the X direction and the Y direction, so that the roof surface is covered with the roof shingle as shown in FIG.

As a result, as is apparent from FIGS. 7 and 8, at the overlapping portion, at least the edge 2 of the bulging portion is formed.
has a width (W) corresponding to the distance between the bending position a ₁ of a and the upper edge portion 3a, also the lateral groove 11A having a depth corresponding to the height of the bulge portion 2 is formed, the An overlapping line 12A of each engaging portion running in the X direction is formed in the lateral groove 11A.

A vertical groove 11B is formed in the overlapping portion of the right engaging portion and the left engaging portion, and an overlapping line 12B of each engaging portion is formed therein. Therefore,
In the case of a roof with the roof plate A1, for example, during rainfall, rainwater flows through the vertical groove 11B and also flows through the horizontal groove 11A. In this case, the rainwater flows relatively quickly without stagnating in the vertical groove 11B, so that water leakage from the overlapping line 12B is unlikely to occur. Water may leak to the roof.

In order to surely solve such a problem,
In the present invention, an engagement method as shown in FIGS. 9 and 10 is performed. The method of engagement will be described below for a roof plate A3 as follows. The roof plate A3 has the same configuration as the swelling portion 2 and the inside of the roof plate A1, but at least the structures of the upper engaging portion 3 and the lower engaging portion 4 are different.

First, the upper edge 3 of the metal sheet 1 shown in FIG.
a is a bent position a ₁ from the Z direction after being slightly bent in the -Z direction, further, the tip 3b of the bent portions of the two by being bent to folded in the Z direction toward the Y-direction An upper engaging portion 3 having a bent structure is formed. On the other hand, the lower edge 4 of the sheet metal 1 shown in FIG. 3, first, that occasion song position a ₂
Folds in two from the -Z direction to the Y direction.
The bent portion is continued after being slightly bent in the -Z direction at the folded position a _21, a further three bent structure by being slightly bent in the Z direction at the bending position a ₂₂ Lower engaging part 4
Are formed.

In the lower engaging portion 4, the edge 2
b and folded position a ² between the length of, and length between the folded position a ₂ and bending position a ₂₁ is substantially equal, also during bending position a _{2 1} a bending position a ₂₂ Is approximately equal to the length of the edge 2b of the shingle. As shown in FIG. 9, when the roof shingles A3 are engaged with each other, first, the lower engaging portions of the roof shingles A3 to be roofed are fitted to the upper engaging portions 3 of the roof shingles A3 'already laid on the roof surface 10. The joint 4 is engaged. Then, the vicinity of the edge 2b of the roof shingle A3 is pressed in the -Z direction.

As a result, as shown in FIG.
Bending position a from edge 2b of A3_TwoUp to the roof shingle A
Covers the top of 3 'and hides all remaining bends underneath
Will be. At this time, the edge 2b and the bending position a₁Length between
The bending position a_TwoAnd bending position a _{twenty one}Equal to the length of
The roof shingle A3 overlaps the edge of the roof shingle A3 ', and
It will not be pushed down, and_{twenty one}And folding
Song position a_{twenty two}The length between them is approximately equal to the length of the edge 2a of the shingle A3 '.
Since they are equal, they are in a state of fitting to the edge. And
The tip 3b of the upper engaging portion 3 of the roof shingle A3 'is below the roof shingle 3.
A bar structure is formed in contact with the surface.

Therefore, in this engaged state, the lateral groove 12 as shown in FIG. 8 is formed at the overlapping portion of the upper engaging portion 3 of the roof plate A3 'and the lower engaging portion 4 of the roof plate 3.
No A is formed, and the overlapping line of both is located on the upper surface of the roof shingle A3 '. Therefore, even when it is raining, the leakage of rainwater to the roof surface 10 is greatly suppressed, and even if it is flooded from the overlapping line, it is waterproof to the roof surface 10 which is waterproofed by the return structure including the tip 3b. Water leakage can be reliably prevented.

By the way, according to the engagement method shown in FIGS. 9 and 10, when roofing is performed, the roof plate A3 and the roof surface 1
0, the space 11 in which the shape of the YZ plane is wedge-shaped is X
Formed in the direction. Therefore, when an operator rides on the shingle during the roofing work, the shingle may be crushed by its weight. In consideration of such a problem, the present invention provides the following engagement method. The case where the roof shingle A3 is engaged with the roof shingle A3 'shown in FIG. 10 will be described.

First, a plate material 12 whose YZ plane shape is similar to the side surface shape of the space 11 shown in FIG. 10 is prepared.
Then, as shown in FIG. 11, one corner of the plate member 12 is fixed to the roof surface 10 with, for example, a nail 13. At this time, the inclined surface 12a of the plate member 12 is the roof plate A3 'already roofed.
Center is located on a portion between the folded position a ₁ and the end portion 3b of the upper engaging portion 3, also the bottom surface 12b is placed in contact with the roof surface 10 and plate 12 is a nail 13 To move in the XY plane.

In this state, the lower engaging portion of the roof shingle A3 which is to be newly roofed next is connected to the roof shingle A3 as shown in FIG.
3 'engages with the upper engaging portion 3. And the shingle A
At the same time as pressing 3 in the -Z direction, the plate 12 is moved in the direction of the arrow q around the nail 13 as shown in FIG. At this time, the plate 12 is made up of the roof plate A3 ′ and the roof plate A
