Description

The present invention makes it possible to repair a roof while effectively utilizing the flat slate that is still on the roof without removing the flat slate thatched on the roof and re-roofing a new flat slate. Regarding materials.

The roofing material for flat slate repair has traditionally made it possible to repair the roof while effectively utilizing the flat slate that remains on the roof without removing the flat slate thatched on the roof and re-roofing a new flat slate. It is known (see, for example, Patent Document 1).

The roofing material for repairing flat plate slate described in Patent Document 1 is composed of a metal roofing material that covers the upper surface of the flat plate slate and also covers the upper water end portion and the lower water side end portion, and has a folded portion on the lower water side. The structure is such that the entire flat slate roofing material is covered with a metal insert roofing material by connecting the flat slate roofing materials from the eaves of the roof to the bottom of the eaves while covering them.

Then, in connecting the roofing materials arranged so that the inserted roofing materials are from the eaves side to the eaves bottom side, as described in paragraph (0011) of Prior Art Document 1, a sticking agent such as silicon is used. The roofing material for repairing the flat plate slate is adhered and fixed to each flat plate slate using the above.

Utility Model Registration No. 3197644

The roof is hot in the summer due to direct sunlight, and in the winter it gets cold and snow accumulates. In addition, it is frequently exposed to extremely strong rain and wind such as huge typhoons and torrential rains accompanied by strong winds due to abnormal weather in recent years. Moreover, once the roof is constructed, it will be used as it is for an extremely long period of time.

Considering these points, in the above-mentioned prior art document, even if the flat plate slate to which each insertion roofing material is attached is adhered with a sticking agent such as silicon at the time of construction, in the above-mentioned harsh environment. There is a good possibility that the adhesive portion will deteriorate and peel off after a long period of time.

Once the adhesive part is peeled off, each insert roofing material shifts or floats with respect to the slate roofing material. Therefore, for example, due to the above-mentioned typhoon or storm caused by a huge low pressure system, there is a danger that the roofing material will slide down under the eaves of the roof, the roofing material will fall, or the roofing material will be blown away by the wind and fly in the air. Sex is also possible.

In addition, the slate roofing material that is no longer firmly fixed by the insertion roofing material breaks and becomes fragments that also separate from the roof, causing the insertion roofing material to fall or to be blown away by the wind and fly in the air. There is also a risk of doing so.

If such insert roofing material is peeled off from the slate roofing material that covers it individually, and the slate roofing material or insert roofing material falls from the eaves or flies into the air due to strong winds, people walking in the vicinity. There is a risk of causing a serious accident such as hitting the roof. Similarly, there is a risk of hitting a vehicle parked in the vicinity and seriously damaging the vehicle.

In addition to the above-mentioned problems, in performing the construction of covering the slate roofing material with the insertion roofing material according to the prior art document 1, as described above, the adhesive such as silicon is surely applied to both of them firmly. Since it is necessary to join with, the installer may inadvertently forget to apply a part of the coating during construction, or the coating amount may be insufficient and sufficient bonding strength may not be maintained.

Further, if the size of the roof is large, it is necessary to surely apply a sticking agent such as silicon to the entire joint portion, which requires a considerable number of construction man-hours. In addition, since it is necessary to perform the coating work when the weather is good, there is a possibility that the roof repair schedule may be delayed depending on the good or bad weather.

An object of the present invention is to solve the above-mentioned problems associated with the insert roofing material, and to provide a roofing material for repair that is easy to install and has excellent durability and safety that is not affected by bad weather for a long period of time.

The first additional structural feature is that a gap is formed between the inside of the side folded portion 120 and the inside.

Further, in the present embodiment, as shown in FIGS. 4 and 8 (a), the flat plate slate repair roofing material 102 (100) is viewed in a state where the flat plate slate repair roofing material 100 is attached to the flat plate slate 50. In the inner recessed portion 155 of the underwater side convex ridge bending portion 150, the water upper ridge bent portion 160 of the flat plate slate repair roofing material 101 (100) covered with the flat plate slate 50 adjacent to the underwater side. The top portion 165a of the protrusion 165 of the above is in contact with the roof material 102 for repairing the flat plate slate, and the standing portion 151 on the underwater side of the ridge bending portion 150 on the underwater side and the roof for repairing the flat plate slate on the underwater side. The water-up side ridge bending portion 160 of the material 101 is separated from the water-side upright portion 161 by a predetermined length.

Further, in the present embodiment, when the roofing material 100 for flat plate slate repair is attached to the flat plate slate 50, the water side upright portion of the underwater convex strip bent portion 150 of the roofing material 102 (100) for flat plate slate repair is seen. The 152 and the water-up rising portion 162 of the water-up ridge bending portion 160 of the flat plate slate repair roofing material 101 (100) below the water are separated by a predetermined length. The above configuration is a second additional configuration feature of the present embodiment.

It should be noted that, in the vicinity of one end of the flat plate slate repair roofing material 100 according to the present embodiment in the longitudinal direction, a screw fixing indicating a preferable screwing position for fixing the flat plate slate repair roofing material 100 to the flat plate slate 50 is indicated. The positioning marking 101 is formed in advance (see FIG. 2). However, this screwed positioning marking 101 is not an essential component according to the present invention.

Further, overlapping line markings for forming laterally overlapping fitting joints 100x and 100x'(see FIG. 6) at a distance from the flat plate slate repairing roofing material 100 adjacent to the flat plate slate repairing roofing material in the lateral direction. 102 is made (see FIG. 2). However, this overlapping line marking 102 is not an essential component according to the present invention.

Since the screw-fixed positioning marking 101 overlaps and is marked on the longitudinal end side of the flat plate slate repair roofing material 100 with respect to the line marking 102, the flat plate slate repair roofing material 100 adjacent to the flat surface portion 110 is fitted. When they are combined together, the head 910 of the screw 900 that has already appeared on the roofing material 100 for repairing the flat slate that has been screwed to the flat slate 50 is hidden and invisible (see FIG. 5).

More specifically, the portion for fixing the flat plate slate repair roofing material 100 and the flat plate slate 50 using the screws 900 surrounded by the dotted lines shown in FIGS. 3 and 4 is not shown in these drawings, but is actually shown in the drawings. As clarified in 5, a part of the end portion of the adjacent lateral flat plate slate repair roofing material 100 of each flat plate slate repair roofing material 100 covers the screw 900, and the head 910 of this screw 900 is covered. The portion of the head 910 of the screw 900 is covered, and is not exposed to the outside by the lateral flat surface portion 110 of the roofing material 100 for repairing the flat plate slate so that it cannot be seen from the outside.

Then, when the roofing material 100 for repairing the flat plate slate was attached to the roof of the flat plate slate 50 in order from the left wife side to the right wife side as shown in FIG. The roofing material 100L for repairing the flat plate slate on the left side (see FIG. 5) is covered with the roofing material 100R for repairing the flat plate slate on the right side (see FIG. 5) at the laterally overlapping fitting portion 100x of the screw 900. The 910 is covered with the flat surface portion 110 of the roofing material 100R for repairing the flat plate slate on the right side.

Subsequently, a procedure for repairing the flat plate slate repairing material 100 according to the present embodiment will be described by attaching the roofing material 100 for repairing the flat plate slate to the roof actually covered with the flat plate slate 50.

First, the flat plate slate repair roofing material 100 is fixed to the flat plate slate 50 on the watermost side of the roof, that is, on the ridge side, on one end side with an adhesive. At this time, due to the action of the present invention, it is not necessary to apply a large amount of adhesive to the flat plate slate 50 to attach the roofing material 100 for repairing the flat plate slate as in the conventional case.

Next, using the screw fixing positioning marking 101 near the end on the end side (one end) and the end on the opposite side as a guide for the mounting position of the screw 900, the roof material 100 for repairing the flat plate slate is used as a flat plate slate. Screw it to 50.

Then, when the flat plate slate repair roofing material 100 is connected to and attached to each flat plate slate 50 along the ridge, one water upper convex ridge bending portion 160 of the adjacent flat plate slate repair roofing material 100 and the other water upper side. The ridge bent portions 160 are fitted to each other by a predetermined length in the longitudinal direction.

Similarly, one of the underwater side ridge bent portions 150 and the other underwater side ridge bent portion 150 of the adjacent flat plate slate repair roofing material 100 are fitted to each other by a predetermined length in the longitudinal direction.

In this way, by superimposing the roofing material 100 for repairing one flat plate slate and the roofing material 100 for repairing the other flat plate slate by a predetermined length in the longitudinal direction, both roofing materials 100 for flat plate slate repair are overlapped with each other. To combine.

With respect to this overlapping predetermined length, the length of the flat plate slate repair roofing material 100 coupled to the overlapping line marking 102 on the other end side of the flat plate slate repair roofing material 100 already attached to the flat plate slate 50. The vicinity of one end of the direction is overlapped and connected.

The length of the roofing material 100 for repairing the flat plate slate in the longitudinal direction is constant, but the width from one gable side to the other gable side of the roof is naturally different for each building. Therefore, the adjacent laterally overlapping fitting joints (reference numerals 100x and 100x'in FIG. 6) of the flat plate slate repair roofing material 100 in the longitudinal direction are appropriately changed according to the size of the roof of each building.

As a result, the longitudinal end of the flat plate slate repair roofing material 100 is adjusted to the size of the roof. In this way, the troublesome work of cutting to match this is not required at the construction site.

This is the lateral overlap of the roofing materials for flat plate slate repair of the roofs of the first and second floors in FIG. 6, and the lateral overlap of only the rightmost side in the downward-sloping hatching portion indicating the fitting joints 100x and 100x'. The fitting joint portion 100x'is wide, and by increasing the overlapping width at this portion, the flat plate slate repair roofing material 100 having the same length in the lateral direction of the roof can be commonly used. It shows that it can be done. That is, as shown in FIG. 6, it can be seen that according to the present invention, the allocation of the roof of the building can be easily adjusted.

On the other hand, as shown in FIG. 6, the allocation of the roof of the building is not adjusted by changing the width of only a part (right side in FIG. 6) of the lateral overlap fitting joint portion 100x', but the adjacent lateral overlap fitting By increasing or decreasing the overlapping width between the joints at the time of roof renovation, the dimensions of the flat slate renovation roofing material 100 can be shared, and the roofs of various buildings having all lateral dimensions can be used. It may correspond to the repair.

Even when the width of the horizontal overlapping fitting joint 100x is changed without matching the marking line that defines the horizontal overlapping width described above, the screw 900 for fixing the roofing material 100 for repairing the flat plate slate is 900. It is preferable to dimension the overlapping area so that the head 910 is not exposed from the upper part of the flat plate slate repair roofing material 100 and is covered by the adjacent flat plate slate repair roofing material 100.

Subsequently, the flat plate slate repair roofing material 100 is attached to each flat plate slate adjacent to the underwater side. At this time, after applying the adhesive to the above-mentioned flat plate slate, underwater between the folded extending portion 125 of the roofing material 100 for repairing the flat plate slate on the water side and the flat plate slate 50 on the underwater side in contact with the folded extending portion 125. Insert the water upper insertion portion 130 of the roofing material 100 for repairing the flat plate slate on the side, and enter the inner recessed portion 155 of the ridge bending portion 150 on the underwater side of the roofing material 100 for repairing the flat plate slate on the water side from the waterside. The entire protruding portion of the water-side convex ridge bending portion 160 of the inserted flat roof slate repair roofing material 100 is fitted (see the structure shown in FIGS. 2 to 4).

Then, using the screw fixing marking 101 near one end of the flat plate slate repair roofing material 100 as a mark, the screw 900 is driven in, and the flat plate slate repair roofing material 100 is attached to the flat plate slate 50. Next, the flat plate slate repair roofing material 100 is attached to the flat plate slate 50 from one wife side to the other wife side of the roof in the same procedure as the flat plate slate repair roofing material 100 in the first row.

In the above procedure, the second row of flat plate slate repair roofing material 100 is attached from the ridge to the underwater side in the direction parallel to the ridge. In such work, like the roofing material 100 for repairing the flat plate slate in the first row closest to the ridge, the water-side convex ridge bending portions 160 of the roofing material 100 for repairing the flat plate slate adjacent to each other are fitted together. By fitting the underwater convex ridge bending portions 150 of the roofing materials for flat plate slate repair 100 adjacent to each other, the adjacent roofing materials 100 for flat plate slate repair are joined with a constant overlapping width (FIG. 5 and FIG. (See FIG. 6).

In this way, the flat plate slate repair roofing material 100 is covered with the flat plate slate 50 from the ridge to the eaves one row from the upper side to the lower side of the water.

By performing the above work from the ridge to the eaves, on the entire upper surface of the flat plate slate of the roof, the water-up convex ridge bending portions 160 of the roofing material 100 for repairing all the flat plate slate are formed in the direction parallel to the ridge. At the same time as fitting, the submerged side ridge bent portions 150 are fitted together.

In addition to this, in the direction of water flow, the underwater ridge bending portion 150 of the roofing material 100 for repairing the flat plate slate on the water side and the ridge bending on the water side of the roofing material 100 for repairing the flat plate slate on the water side All the portions 160 are fitted together. As a result, as shown in FIG. 6, the roofing material 100 for repairing the flat plate slate is attached as if the upper surface of the entire roof covered with the flat plate slate 50 is integrally covered.

Below, a more specific procedure of the roofing material for repairing a flat plate slate will be described in more detail with reference to FIG. Note that FIG. 6 shows a shape in which the number of flat plate slate and roofing material for repairing flat plate slate is considerably smaller than the actual number for convenience of explanation, but the actual dimensions of the flat plate slate are water flow. With the direction as the vertical, for example, the width is 1 meter and the length is 40 cm, and the dimensions of the roofing material for flat plate slate repair are, for example, 1.2 meters in width and 30 cm in length.

Therefore, when roofing a standard building, for example, on the roof of the first floor or the roof of the second floor, the first floor part shown in FIG. 6 is 6 horizontal and 4 vertical, and the 2nd floor is 6 horizontal and 3 vertical. However, in reality, the flat plate slate 50 has as many as 20 to 30 sheets in the horizontal direction and 20 sheets in the vertical direction as an example. Further, with respect to the roofing material 100 for repairing the flat plate slate, a large number of corresponding sheets will be mounted on the flat plate slate of the roof.

Subsequently, an attachment procedure when attaching the roofing material 100 for repairing the flat slate to the flat slate 50 of the roof on the first floor will be described with reference to FIG. 6 schematically shown. First, attach adhesive to the flat plate slate 50 on the gable side (left side in the figure) at one end of the roof on the first floor and on the water side (the uppermost side where four sheets are lined up from the water surface to the water bottom in the figure). The roofing material 100 for repair is fitted and fixed with screws.

Subsequently, a second flat plate slate repair roofing material 100 is attached to the right side of the flat plate slate repair roofing material 100 attached to the flat plate slate 50 so as to cover the adjacent flat plate slate 50. At this time, as in the case of the first sheet described above, an adhesive is attached to the flat plate slate 50, and the second flat plate slate repair roofing material 100 is fitted into the flat plate slate 50 to which the flat plate slate 50 is attached, and the first sheet is attached. The underwater folded portion (for example, 120 L in FIG. 5) of the roofing material 100 for repairing the flat plate slate is covered with a part of the second underwater pushed portion (for example, 120R in FIG. 5) in the longitudinal direction.

At the same time, the second underwater convex bending portion (for example, 150R in FIG. 5) is overlapped with the first underwater convex bending portion (for example, 150L in FIG. 5) by a certain width in the longitudinal direction. Cover and fit from above.

Similarly, the second water-up convex bending portion (for example, 160R in FIG. 5) is overlapped on the first water-up convex bending portion (for example, 160L in FIG. 5) by a certain width in the longitudinal direction. Cover and fit. Further, a second convex bent portion for preventing water intrusion (for example, 170R in FIG. 5) is placed on the first convex bent portion for preventing water intrusion (for example, 170 L in FIG. 5) with a constant width in the longitudinal direction. Cover and fit from above so that they overlap.

As a result, the second flat slate repair roofing material is placed on the right end of the first flat slate repair roofing material by a certain width, including the part attached to the flat slate with screws. It is attached to the second flat plate slate so that it overlaps. That is, the laterally overlapping fitting joint portion 100x shown by the hatching that rises to the left in FIG. 6 can be formed over the entire roof.

In this way, the third flat plate slate repair roofing material 100 is attached to the third flat plate slate 50 adjacent to the right side in the same procedure, and this is continuously connected to the gable side at the right end in FIG. Continue the same work. Since the distance from one gable side to the other gable side differs depending on each building as described above, as shown in FIG. 6, the rightmost roofing material 100 and the two adjacent flat slate roofing materials 100 The allocation of the roof is adjusted by making the overlapping width of the laterally overlapping fitting fitting joint portion 100x'wider than that of the laterally overlapping fitting fitting joint portion 100x of the other portion.

However, unlike FIG. 6, the lateral overlap width of each flat plate slate repair roofing material is evenly widened slightly larger than the overlap width of reference numeral 100x indicating the lateral overlap fitting joint shown in FIG. The allocation may be adjusted so that the overlap width is smaller than the overlap width of 100x'.

In this way, after attaching the roofing material 100 for repairing the flat plate slate to all of the flat plate slate 50 in the first row on the water side of the first floor of the roof, basically the same procedure is followed for each of the second row from the water side. A roofing material 100 for flat plate slate repair is attached to each of the flat plate slate 50, and then, the flat plate slate repair is performed on each of the flat plate slate 50 closest to the eaves on the lowermost side in the third row, the fourth row, and so on. The roofing material 100 is attached.

The difference between the installation procedure in the first row and the second and subsequent rows is that, as shown in FIG. 4, the roofing material 100U for repairing the flat plate slate on the water side covered with the flat plate slate 53D (50) on the water side is underwater. When fitting the roofing material 100D for repairing the flat plate slate adjacent to the side, the water upper insertion portion 130D of the roofing material for repairing the flat plate slate on the underwater side is extended by folding back the roofing material 100U for repairing the flat plate slate on the water side. It is inserted from underwater to above water between the portion 125U and the upper surface of the flat plate slate 52D (50) on the underwater side.

In this insertion work, the water-up side convex bending portion 150U of the water-up side flat plate slate repair roofing material 100U was inserted into the inner recessed portion 155U of the water-side convex bending portion 150U, and the water-side convex bending portion 160D of the water-side flat plate slate repair roofing material 100D. The entire protruding portion 165D of the above is fitted, and the roofing materials 100U and 100D for repairing flat plate slate on the water upper side and the water lower side are fixed to each other. In this way, the water flow direction overlapping fitting joint 100y between the roofing materials for flat plate slate repair adjacent to the water flow direction shown by the hatching that rises to the right in FIG. 6 can be formed over the entire roof. Then, all the flat plate slate 50 of the roof on the first floor is repaired with the flat plate slate repair roofing material 100 according to the present invention. By such repair work, the entire roof made of the flat plate slate 50 on the first floor is covered with the flat plate slate repair roofing material 100 which is integrated equal to the size of the roof. The repair work of the roof on the second floor shown in FIG. 6 is the same as that on the roof on the first floor.

In this way, even a worker who is unfamiliar with roof repair can complete the roof repair quickly and reliably. Further, according to the present invention, by performing the roof repair work, as shown in FIG. 6, the overlapping areas 100x and 100y indicated by the hatching of the right shoulder rising and the right shoulder falling are adjacent to each other of the flat plate slate repair roofing material 100. It can be combined as a fitting portion and constructed as an integrated flat slate repair roofing material that covers the entire roof.

It should be noted that the 100y shown in FIG. 6 which is the overlapping fitting joint portion in the water flow direction and the 100x and 100x'shown in FIG. 6 which are the overlapping fitting coupling portions in the lateral direction are not completely fixedly coupled to each other. It is connected with a so-called play part where the deviation of is allowed.

Specifically, with respect to the play portion at 100y in the water flow direction, the water upper ridge bent portion adjacent to the water side ridge bent portion fitted in the recessed portion of the water lower ridge bent portion (for example, 150 U shown in FIG. 4). (For example, 160D shown in FIG. 4) is defined within a deviation range. Further, particularly for 100x and 100x'in the lateral direction, the fitting form is such that the roofing material for repairing each flat plate slate can be displaced in the longitudinal direction. And even if both of them deviate within the range of the play, they have no effect on the prevention of rainwater intrusion.

Due to such a structural feature peculiar to the present invention, for example, even if a large earthquake occurs and the house shakes, the play between the above-mentioned adjacent roofing materials for flat plate slate repair absorbs the shaking. Even if the flat plate slate covered by this is cracked, by firmly covering it with the flat plate slate repair roofing material that integrates them, the flat plate slate itself peeled off from the roof and the broken flat plate slate fragments can be removed from the eaves. The flat slate repair roofing material that has fallen or peeled off from the flat slate will not fall from the eaves.

This is an example of the basic installation procedure, and is a roofing material for flat plate slate repair from one end side (left side in FIG. 6) to the other end side (right side in FIG. 6) of the roof gable side. It goes without saying that the roofs may be installed in order from the other end side (right side in the figure) to the one end side (left side in the figure) on the wife side of the roof.

Since the roofing material for flat plate slate repair according to the present embodiment has such a configuration, the entire upper surface of the roof of the flat plate slate can be covered with the roofing material for flat plate slate repair. As a result, the problems associated with the insert roofing material described in the section of the problem to be solved of the present invention can be solved at once, the construction is easy, and the durability and safety are not affected by bad weather for a long period of time. An excellent roofing material for renovation can be provided. Specifically, it is as follows.

The roof is hot in the summer due to direct sunlight, and in the winter it gets cold and snow accumulates. In addition, it is frequently exposed to extremely strong rain and wind such as huge typhoons and torrential rains accompanied by strong winds due to abnormal weather in recent years. Moreover, once the roof is constructed, it will be used as it is for an extremely long period of time.

In consideration of these points, in the prior art document 1 introduced in the background art, even if the flat plate slate to which each insertion roofing material is attached is adhered with an adhesive such as silicon at the time of construction, the above-mentioned fierceness is taken into consideration. In such an environment, there is a good possibility that the adhesive portion will deteriorate and peel off after a long period of time.

Once the adhesive part is peeled off, each insert roofing material shifts or floats with respect to the slate roofing material. Therefore, for example, due to the above-mentioned typhoon or storm caused by a huge low pressure system, there is a danger that the roofing material will slide down under the eaves of the roof, the roofing material will fall, or the roofing material will be blown away by the wind and fly in the air. Sex is also possible. In addition, the slate roofing material that is no longer firmly fixed by the insertion roofing material breaks and becomes fragments that also separate from the roof, causing the insertion roofing material to fall or to be blown away by the wind and fly in the air. There is also a risk of doing so.

If such insert roofing material is peeled off from the slate roofing material that covers it individually, and the slate roofing material or insert roofing material falls from the eaves or flies into the air due to strong winds, people walking in the vicinity. There is a risk of causing a serious accident such as hitting the roof. Similarly, there is a risk of hitting a vehicle parked in the vicinity and seriously damaging the vehicle.

In addition to the above-mentioned problems, when performing the construction of covering the slate roofing material with the insertion roofing material according to Prior Art Document 1, as described above, the adhesive such as silicon is surely applied to each of them to firmly apply both. Since it is necessary to join, there is a possibility that the installer inadvertently forgets to apply a part of the coating during the construction, or the coating amount is insufficient and sufficient bonding strength cannot be maintained.

Further, if the size of the roof is large, it is necessary to surely apply a sticking agent such as silicon to the entire joint portion, which requires a considerable number of construction man-hours. In addition, since it is necessary to perform the coating work when the weather is good, there is a possibility that the roof repair schedule may be delayed depending on the good or bad weather.

However, according to the roofing material for flat plate slate repair according to the present embodiment, all the problems described above can be solved.

In addition to the above-mentioned actions of the present embodiment, the actions of the first additional structural feature in the present embodiment will be described. Since the present embodiment has such a first additional structural feature, when the roofing materials for flat plate slate repair are connected and connected in the lateral direction, they overlap in the lateral direction with a certain length. In forming the fitting joint, the underwater folded portion is not bent at an angle unlike the underwater end of the flat plate slate, so that the roofing materials for repairing the flat plate slate in the lateral direction can be easily overlapped with each other.

This makes it easy, quick, and reliable to join the roofing materials for flat plate slate repair, which are adjacent to each other in the lateral direction from one gable side to the other gable side, in a fitted state over a part in the longitudinal direction. It can be done, and even a builder who is not accustomed to the work can safely and efficiently repair the roof. As a result, it is possible to eliminate the delay in the schedule regarding the installation of the roof material for the flat plate slate repair.

Subsequently, the action due to the second additional structural feature in the present embodiment will be described. Since the present embodiment has such a second additional structural feature, the underwater ridge bent portion of the roofing material for repairing the flat plate slate on the water side and the roof for repairing the flat plate slate on the water side The water-up convex folds of the material do not completely overlap, and the upright part of the water-up ridge fold of the roofing material for repairing the flat plate slate on the underwater side and the flat plate slate on the water side that covers it. A certain space can be formed between the roofing material for repair and the upright portion of the ridge bent portion on the underwater side.

Based on such a configuration, this space prevents water from climbing over the water-up convex ridge bending portion of the roofing material for repairing the flat plate slate on the water side due to the capillary phenomenon, and the roofing material for repairing the flat plate slate on the water side. Prevents water from entering the upper surface of the flat slate covered with. As a result, water leakage into the building can be reliably prevented.

It should be noted that even a form having only one of the above-mentioned first additional structural feature and the second additional structural feature, or a form having neither of them is within the scope of the present invention. It goes without saying that it belongs. However, having these additional structural features is preferable from the viewpoint that the above-mentioned actions can be synergistically exerted.

Subsequently, each modification of the above-described embodiment will be described. FIG. 7 is an end view showing various deformation examples of the roofing material for repairing a flat plate slate according to an embodiment of the present invention, and a partially enlarged view of each.

In FIG. 7A, the water-side convex ridge bending portion 150a of the folded extending portion 125a is formed as a wide end-view curved bulge portion of the inner recessed portion 155a. Further, the water-upper ridge bent portion 160a is formed in a semicircular shape when viewed from the end face. Further, on the water upper side of the water upper ridge bent portion 160a, a ridge bent portion 170a for preventing rainwater intrusion is formed having a semicircular end face view.

Further, in FIG. 7B, the underwater ridge bent portion 150b of the folded extending portion 125b is formed as a ridge bent portion having a triangular shape in terms of end face view. Further, the water-upper ridge bent portion 160b is formed in a triangular shape in view of the end face.

Further, in FIG. 7C, the submerged convex folds 150c of the folded extension portion 125c are separated from each other by a predetermined distance as two ridges bent portions 150c-1 and 150c-2 having a semicircular end face view. Are formed respectively. On the other hand, on the water upper side, two water side convex ridge bending portions 160c-1 and 160c-2 having a triangular shape in terms of end face are formed at a certain interval from each other.

Of the two underwater ridge bent portions 150c-1 and 150c-2 of the folded portion 125c, the underwater ridge bent portion 150c-1 formed on the underwater side has two water-upward convex portions. Of the strip bent portions, it is formed on the water bottom side and corresponds to the water side convex strip bent portion 160c-1.

Similarly, of the two water-upper ridge bends 160c-1 and 160c-2, the water-side ridge bend 150c-2 formed on the water side is on the water of the two water-up ridge bends. It corresponds to the water upper ridge bent portion 160c-2 formed on the side.

As a result, one of the underwater side of the water-up convex ridge bending portion of the roofing material for repairing the flat plate slate covered with the flat plate slate on the underwater side is covered with the flat plate slate adjacent to the water side of the flat plate slate. It fits into one of the underwater side of the folded extension part of the roofing material and the underwater side of the slate bent part.

In addition, the other side of the water side convex ridge bending portion of the roof material for flat plate slate repair covered on the flat plate slate on the underwater side is the roof for flat plate slate repair covered on the flat plate slate adjacent to the water side of this flat plate slate. It fits into the other side of the water side of the water side convex strip bending part of the material folded extension portion 125.

In this way, by blocking the ingress of rainwater at the combination of the two convex ridge bends toward the upper side of the water, it is possible to prevent the ingress of rainwater reliably, prevent rain from leaking into the building, and thoroughly stop the rain. Can be made to.

Subsequently, a further modification of the above-described embodiment will be described. FIG. 8 shows the water side of the roofing material for repairing the flat plate slate on the water side in the recessed portion of the ridge bending portion on the water side of the roofing material for repairing the flat plate slate on the water side according to the embodiment of the present invention and each modification thereof. It is a drawing which shows the state in which the ridge bent part is fitted, respectively.

Regarding the fitting form of each convex ridge bent portion shown in FIG. 8, for example, a roofing material for repairing a flat plate slate covered on a flat plate slate (not shown) on the underwater side and a flat plate slate adjacent to the water upper side thereof. In combination with the roofing material for flat plate slate repair covered on (not shown), the water-side convex ridge bending part of the roofing material for flat plate slate repair on the water side is folded back from the roofing material for flat plate slate repair on the water side. It shows a form in which it is fitted into the inner recessed portion of the slate bent portion on the underwater side of the existing portion.

In each drawing, the dimensional relationship of each flat plate slate repair roofing material in the vertical and horizontal directions is drawn as an example for easy understanding of the structure, and the actual dimensional relationship is shown. Is different from.

Specifically, FIG. 8A shows the configuration of one embodiment of the present invention described above, and is a semicircle of the end face of the folded-back extending portion of the roofing material 101 (100) for repairing a flat plate slate on the water side. The end face view of the roofing material 102 (100) for repairing the flat plate slate on the underwater side is fitted in the inner recessed portion 155 of the circular underwater side convex ridge bending portion 150. It shows the matching state.

In this case, between the underwater side upright portion 151 of the underwater side ridge bending portion 150, the underwater side upright portion 152, and the underwater side upright portion 161 and the water upside upright portion 162 of the water upper side ridge bending portion 160, respectively. They are fitted to each other at a certain distance from each other, and two spaces for preventing water intrusion are formed in the inner recessed portion 155 of the submerged side convex strip bent portion 150.

Next, various modifications different from this modification will be described. Since the basic configuration is the same as that shown in FIG. 8A, the corresponding reference numerals are attached to the drawings by changing only the numbers in the 100s.

Regarding FIG. 8 (b), instead of the water-upper convex fold portion 160 having a substantially isosceles triangle shape in the end face view in FIG. 8 (a), the water upper ridge bend portion 260 having a substantially semicircular end face view is fitted. doing. Other configurations are the same as in FIG. 8A.

Further, in the fitting state of FIG. 8 (c), instead of the water-side convex ridge bending portion 150 having a substantially semicircular end face view in FIG. 8 (a), the water-side convex having a substantially isosceles triangle shape in end face view. The strip bent portion 350 is fitted. Other configurations are the same as in FIG. 8A.

Further, with respect to FIG. 8 (d), instead of the water-upper convex fold portion 360 having a substantially isosceles triangle shape in the end face view in FIG. 8 (c), the water upper ridge bend portion 460 having a substantially semicircular end face view is used. It is fitted. The other configurations are the same as in FIG. 8 (c).

Further, with respect to FIG. 8 (e), the water upper convex having a substantially irregular semicircular end face view in the inner recessed portion 555 of the underwater side convex strip bent portion 550 having a substantially semicircular end face view in FIG. 8 (a). The bent portion 560 is fitted. In this modification, only between the underwater standing portion 551 of the underwater ridge bending portion 550 and the underwater standing portion 561 of the underwater ridge bending portion 560 is separated from the above-mentioned modification. A space is formed between the two to prevent water intrusion.

Regarding FIG. 8 (f), the water-upper convex fold portion 560 having a substantially semicircular end face view in FIG. 8 (e) is changed to a convex ridge bend portion 650 having a substantially isosceles triangle shape in end face view, and the end face view Instead of the water-up ridge bent portion 560 having an irregular semicircular shape, the water-up ridge bent portion 660 having a substantially right-angled triangular shape on the end face is fitted. Other configurations are the same as in FIG. 8 (e).

In addition to the above-mentioned modification, when the roofing material for repairing the flat plate slate in the lateral direction is fitted and joined, it is further above the flat plate slate roof which is the upper side of the laterally overlapping fitting joint portion. It may be bent as a whole so as to form a tapered surface so that only the portion that does not overlap with the roofing material for repairing the flat plate slate to be joined faces slightly downward.

Specifically, with reference to the range shown by the dotted line in FIG. 1 and the range shown by the elongated track-shaped dotted line in FIG. 2, the direction of the upper surface of the lower folded plate roofing material on which this overlaps (arrow f in FIG. 1). The above configuration can be realized by slightly tilting it toward the indicated direction).

As a result, when the roofing material for flat plate slate repair in the lateral direction is joined, the end portion of the bent portion on one end side is overlapped in the lateral direction by elastic force and becomes the lower side of the fitting joint portion. Since it is pressed against the upper surface of the roof, it prevents water from entering.

Furthermore, in these laterally overlapping fitting joints, only the ends overlap each other and a gap (space) is formed above and below the inside, so that rainwater does not enter the inside due to the capillary phenomenon. As a result, it is possible to prevent the ingress of rainwater and ensure the end of rain.

Finally, the special advantages of the present invention will be described below in the sense of re-emphasizing. First, by using the roofing material for repairing flat plate slate according to the present invention, as a structural feature of this, for example, special construction is applied to the joint between the roof of the first floor and the wall of the second floor covered with flat slate. It is no longer necessary and can save a considerable amount of labor and cost in construction.

Next, as a first advantage peculiar to the present invention, the underwater ridge bent portion of the roofing material for flat plate slate repair and the water side ridge bent portion of the adjacent underwater flat slate repair roof material overlap. At the same time, the water-upper ridge bends and the water-lower ridge bends of the adjacent flat plate slate repair roofing materials from one gable side to the other gable side of the roof overlap each other in the lateral direction with a certain length. Due to the double structure based on fitting at the fitting joint, it is possible to eliminate an undesired deviation of the joint between adjacent flat plate slate repair roofing materials in both the water flow direction and the lateral direction of the roof.

As a result, it is possible to realize a roof repair method in which the roofing material for flat plate slate repair does not rise independently and the roofing material for flat plate slate repair does not come off separately, and the joints between adjacent flat plate slate repair roofing materials overlap. As a result, the entire roof covered with flat slate can be completely covered by the flat slate repair roofing material that is integrated as if it were integrated.

Next, as a second advantage peculiar to the present invention, in the overlapping fitting joint portion in the water flow direction of the roofing material for flat plate slate repair, the inner dent of the ridge bending portion on the underwater side of the roofing material for flat plate slate repair on the upper side thereof. The top of the water-up convex ridge bending part of the lower flat plate slate repair roofing material is in contact with the part, and spaces are formed on both sides of this, so that the flat plate slate and this in the inner recessed part of the overlapping part Prevent rainwater from entering the gaps between the roofing materials for flat plate slate repair that cover the upper surface due to capillarity.

In this way, it is possible to prevent rainwater from being blown in, which has been a problem with conventional roofing materials for repair. In particular, since a space is formed between the overlapping portions of the roofing material for repairing the flat plate slate, water does not get over the inner protrusions in this portion, which effectively prevents rainwater from being blown in.

Next, as a third advantage peculiar to the present invention, since adjacent roofing materials for flat plate slate repair are joined while being fitted to each other, the number of screwing points for fixing the roofing material for flat plate slate repair to the flat plate slate is reduced. be able to. Specifically, according to the present invention, as shown in FIG. 3, the location of the screw fixing for fixing the roofing material for flat plate slate repair to the flat plate slate is sufficient in the longitudinal direction of the roofing material for flat plate slate repair, for example, one location on the upper right. It has become.

In the conventional structure, a large number of screws were required in order to prevent the roofing material for repairing the flat plate slate from shifting with respect to the flat plate slate covered by the adhesive and the screw fixing. However, when such a large number of screws are used, the flat plate slate itself may crack or the flat plate slate itself may crack due to the difference in the coefficient of thermal expansion between the flat plate slate repair roofing material and the flat plate slate. However, according to the present invention, since the number of screwed parts can be minimized, the occurrence of such a defect can be prevented.

In addition, unlike the conventional roofing material for repairing flat plate slate, it is not necessary to use a large amount of adhesive to fix it to the flat plate slate. This makes it possible to reduce the man-hours required for the adhesive application work, and also to reduce the number of man-hours required for the adhesive application work, and to reduce the number of man-hours required for the adhesive application work. Peeling can be prevented.

Further, according to the conventional structure, in order to prevent the roofing material for repairing the flat plate slate from peeling off from the flat plate slate for a long period of time, the two are often excessively adhered and fixed, and the flat plate slate is similarly bonded and fixed as described above. Due to the difference in the coefficient of thermal expansion between the roofing material for repair and the flat plate slate, the flat plate slate was cracked or cracked itself, but according to the present invention, the occurrence of such a defect can be prevented.

However, according to the present invention, by providing only one screw fixing portion in the vicinity of one end in the longitudinal direction of the roofing material for flat plate slate repair shown in FIG. 3, the roofing materials for flat plate slate repair are placed in the lateral direction of the roof. In the fitted state, it is possible to sufficiently secure lateral slide play of these roofing materials for flat plate slate repair.

Next, as a fourth advantage peculiar to the present invention, the lateral joining dimension (overlapping portion) of the roofing material for flat plate slate repair is determined in advance to an appropriate dimension, and the length of each roofing material for flat plate slate repair in the lateral direction is free. Can be adjusted to. Therefore, it becomes easy to assign the dimensions in the lateral direction.

Naturally, each dimension of the roof of a building is different for each roof, but due to this fourth advantage, different lateral dimensions are used for each building using flat plate slate repair roofing materials with common lateral dimensions. It can be adapted to all flat slate roofs with dimensions. As a result, it becomes possible to share the parts of the roofing material for repairing the flat plate slate, and the problem of inventory control does not occur. In addition, the permissible range of cutting by allocation is increased, and workability is improved.

In addition, the number of places to be screwed is reduced and the time and effort required to apply adhesive is reduced, and the ridge-folded parts of the adjacent flat plate slate repair roofing material from the water upper side to the water lower side are fitted together. At the same time, by fitting the convex protrusions of the roofing material for flat plate slate repair from one gable side to the other gable side of the roof, the roofing material for flat plate slate repair to the flat slate is surely fitted. Since the construction work can be performed while confirming the installation, quick and reliable construction can be performed by an inexperienced person.

Based on each of the advantages described above, it is possible to repair flat plate slate at a low cost in total. As a result, it is possible to repair a flat slate roof that is safe and secure for a long period of time.

Furthermore, since the present invention has the above-mentioned actions, it is possible to cope with shaking such as an earthquake whose time cannot be predicted. In other words, when the earthquake suddenly shakes and you try to go out in a hurry, the flat slate that is damaged and cracked or the roofing material for repairing the flat slate that has peeled off from the flat slate falls and you are injured when you evacuate from your house. There is no such thing as doing. Furthermore, it is possible to prevent the roof from collapsing due to the occurrence of a large-scale earthquake, and it is possible to avoid being forced to live in another place as an evacuation life after the earthquake occurs.

In addition, by having a structure in which the ridges and bends of the adjacent flat plate slate repair roofing materials fit together, it is possible to prevent rainwater from blowing in or invading due to huge typhoons and frequent torrential rains due to abnormal weather in recent years. can do.

In addition, adjacent flat slate repair roofing materials and flat slate repair roofing materials due to shaking and strong winds caused by earthquakes that may occur when the flat plate slate repair roofing materials are individually attached to the flat plate slate. It is possible to prevent an unfavorable deviation from the flat plate slate to which the roof is attached.

In addition, when repairing a flat slate roof as before, the roof can be repaired safely and reliably with simple work without the need for advanced construction technology, so roofs by various contractors can be repaired. Renovation work is possible. As a result, it is not always necessary for a skilled sheet metal worker or the like to repair the roof, and for example, a painter or the like worker can safely, quickly, and reliably repair the roof. As a result, it is easy to secure human resources when repairing the roof, it is possible to prevent delays in the repair schedule, and it is possible to carry out safe, secure, and reliable repair work of the flat slate roof at low cost.

Finally, a further advantage peculiar to the present invention will be described. In recent years, asbestos, which is extremely harmful to the human body as a material for buildings, has been banned from use due to environmental regulations. Until now, it was possible to increase the strength of flat plate slate by including this asbestos, but asbestos cannot be used for new flat plate slate that is roofed after the regulation of asbestos use, so the use of asbestos is restricted. There is a problem that the strength of the new flat slate to be used is weaker than that of the previously made flat slate.

Therefore, when a new building is to be built and the roof is covered with asbestos-free flat slate, various serious problems such as cracks and cracks in the flat slate itself cause the new building to be somewhat long. It may occur prominently after a period of use.

In this case, if the roof is repaired using the conventional roofing material for flat plate slate repair, the roofing material for flat plate slate repair itself is partially peeled off as described in the above-mentioned problem to be solved. If it falls, falls due to an earthquake, or scatters due to a typhoon or strong wind, the flat plate slate with weak strength will be exposed, and this part may be damaged and cause rain leakage in the building.

However, according to the present invention, even such a roof covered with a flat slate-free flat slate having a lower strength than before can be integrally covered with the flat slate repair roofing material of the present invention. Due to the structure, some flat plate slate may fall due to an earthquake, fly away due to a typhoon or strong wind, or partly peel off after a long period of time based on the difference in thermal expansion coefficient between the two. There is no risk of it getting stuck.

Therefore, when such a flat plate slate is laid on the roof in a newly constructed building, when the roof is repaired after a certain period of time has passed, the roofing material for flat plate slate repair according to the present invention can be used. It can be said that it is very significant in solving all the problems.

Further, even when the existing flat slate-covered roof containing asbestos is repaired with the flat slate repair roofing material without changing the flat slate, the conventional flat slate repair roof is used as described above. If the material is used, the roofing material for repairing individual flat plate slate will peel off from the flat plate slate and fall or fly away based on the difference in thermal expansion rate between the two due to long-term use of the roof. There is a risk that the flat slate containing it will be exposed, causing the problem that asbestos will be scattered into the atmosphere from this part.

However, in the case of the present invention, even if the roof is covered with a flat plate slate using existing asbestos as described above, the entire roof can be integrally covered with the flat plate slate repair roofing material according to the present invention. Therefore, asbestos does not scatter in the air from the flat plate slate covered by this.

In addition, since it enables reliable rain storage, if a roof covered with existing flat plate slate containing asbestos is repaired with a conventional roofing material for flat plate slate repair, the rain storage will be insufficient and the roof for flat plate slate repair will be insufficient. Rainwater that has infiltrated between the material and the flat slate eventually falls to the ground in a state containing asbestos, and after the weather recovers, the water evaporates and the dry asbestos is scattered in the atmosphere. However, by using the roofing material for repairing the flat plate slate according to the present invention, such deterioration of the living environment can be prevented.

In addition, when a roof covered with existing flat plate slate containing asbestos is repaired with a conventional roofing material for flat plate slate repair, when the roof is washed with washing water under high pressure, several flat plate slate repair roofing materials are subjected to the pressure. Partially or completely isolated from the flat plate slate containing asbestos, the cleaning liquid directly hits the flat plate slate, or high-pressure cleaning liquid enters through the gap between the adjacent flat plate slate repair roofing materials and covers it. Since it may flow into the flat slate, it may lead to the same deterioration of the living environment as described above.

However, according to the present invention, even if the roof is washed with high pressure, the cleaning liquid does not flow into the flat plate slate due to the structure peculiar to the present invention, and the roof can be safely cleaned while not causing deterioration of the living environment. Can be cleaned cleanly.

As described above, according to the present invention, it is a flat slate containing asbestos whose use is regulated as a building material for the roof of a building which may occur as a serious problem in recent years, and has already been used for the roof. In the future, when the roof is repaired with a flat slate repair roofing material while using the existing flat slate as it is, or when the roof is re-roofed with a new flat slate that does not contain asbestos and has a lower strength than before. It turns out that it is an excellent invention that can solve a problem that is likely to occur remarkably at once.
