Description

The present invention relates to a roof repair method in which a damaged roof of a building is covered with a repair sheet to repair the roof.

In recent years, buildings have been damaged one after another due to natural disasters such as typhoons and heavy rains. In particular, due to the high frequency of typhoons, typhoons may be continuously damaged by the next typhoon without completing the repair of buildings due to the damage of the latest typhoon.

On the other hand, tiled roofs have been used for ordinary houses in Japan for a long time, but if damage is concentrated in a specific area due to a typhoon disaster, it will take half a year to several years from the time of the disaster to the replacement of the tiled roof. There is also. That is, since the tiles are made to order, there are no spare roof tiles, and there is a shortage of roof tile craftsmen, so it takes a long time to start the re-roofing work.

Under these circumstances, from the time of the disaster to the replacement of the tiled roof, the roof is covered with a blue sheet, sandbags are placed on it, and they are pulled with braids to repair the tiled roof as a first aid measure. There is a fact that we are doing.

As a technique for repairing such a tiled roof, for example, a non-slip layer made of a base material in which a non-woven fabric and a reinforcing net are laminated so as to sandwich a porous film and a water-repellent resin formed on one surface of the base material. And an adhesive layer formed on the other surface of the base material, the area of the non-slip layer with respect to the base material is 60 to 90%, and the tensile strength is 200 N / 5 cm or more in the vertical direction and in the horizontal direction. and at 150 N / 5 cm or higher, in the range of moisture permeability 100~5000g / m ² · 24h, and the water pressure resistance 10kPa or more, sheathing curing sheet (Patent transmittance in the wavelength region 400~700nm not less than 40% (See Document 1) and two bags of the same size with substantially square horizontal cross sections capable of accommodating sandbags, which face each other via a band-shaped joint provided with a bag, and the end of the joint on the side of the bag. A sandbag protective bag (see Patent Document 2) has been proposed, which is characterized in that it is open and the other end is closed.

In the conventional repair method using a blue sheet, the normally used blue sheet is vulnerable to rain, wind and direct sunlight, and deteriorates in a few months, so that there is a problem that the blue sheet is torn. In addition, there were problems of secondary disasters such as the braid being cut and the blue sheet being blown off and being caught on the overhead wire, and the sandbags falling. Furthermore, since the heavy sandbags are handled on the roof, skillful skills are required, and it takes a long time for a non-specialized contractor to perform the work, and there is also a problem in safety during work.

An object of the present invention is to provide a roof repair method which can easily and appropriately repair a damaged roof of a building and has excellent durability.

As a result of diligent studies on a method for repairing a damaged roof of a building, particularly a method for repairing a tiled roof until the tiled roof is re-roofed, the present inventor uses an unmanned aircraft to cover the repair range including the damaged part of the roof. By making a repair sheet cut to a size according to the repair range and attaching the repair sheet to the damaged part of the roof, the roof can be repaired easily and appropriately, and the roof is excellent in durability. We found that the roof could be repaired, and completed the present invention.

Further, when repairing a roof having a perforated damaged part in which the roof base material is damaged, the perforated repair range including the perforated damaged part of the roof is further measured, and the size is adjusted according to the perforated repair range. By making a cut base sheet, attaching the base sheet to the perforated damaged part of the roof, installing the foam on it, and then attaching the repair sheet on it, even if the roof is severely damaged, It was found that the roof can be repaired easily and appropriately, and that the roof can be repaired with excellent durability.

The roof repair method of the present invention is a roof repair method in which a damaged roof of a building is covered with a repair sheet to repair the roof, and the repair range including the damaged part of the roof is measured by using an unmanned aircraft. It is characterized by having a step, a repair sheet manufacturing step of manufacturing a repair sheet cut into a size according to the repair range, and a repair sheet mounting step of mounting the repair sheet on a damaged portion of the roof.

Further, in the roof repair method of the present invention, when repairing a roof having a perforated damaged portion in which the roof base material is damaged, the measurement step further measures the perforated repair range including the perforated damaged portion of the roof. Before the repair sheet mounting process, there is a base sheet manufacturing process that prepares a base sheet cut to a size according to the perforated repair range, and a base sheet mounting that attaches the base sheet to the perforated damaged part of the roof. It is preferable to have a step and a foam installation step of spraying a foam material on the base sheet and installing the foam on the base sheet.

In the roof repair method of the present invention, it is possible to easily and appropriately repair a damaged roof of a building. In particular, since the measurement is performed using an unmanned aerial vehicle, there is less work on the conventional roof, and the work can be performed safely. Also, the work can be done by a small number of people. Furthermore, since the installation of the repair sheet does not require skilled skills, even a contractor who does not specialize in roof construction, such as a contractor in a disaster area, can easily perform the work.
Further, the roof repair method of the present invention can be used for roof repair up to the roof re-roofing work in a disaster area or the like.

The roof repair method of the present invention can be used for buildings using roofing materials such as Western roof tiles, Japanese roof tiles, slate, and cement roof tiles.

Hereinafter, the roof repair method of the present invention will be described in detail.
As shown in FIG. 1, the roof repair method according to the embodiment of the present invention sequentially includes a measurement step (S1), a repair sheet manufacturing step (S2), and a repair sheet mounting step (S3).

First, the measurement step (S1) of the present invention will be described.
The measuring step is a step of measuring the repair range including the damaged part of the roof using an unmanned aerial vehicle. This makes it possible to accurately grasp the damaged part of the roof. In addition, it is safe because it is not a measurement performed by climbing on the roof, but a measurement performed by operating an unmanned aerial vehicle from the ground. Furthermore, even one person can perform the work.

Damage to the roof of the present invention means a state in which roofing materials such as roof tiles and slate are lost or destroyed. Further, the damaged portion of the roof of the present invention is a portion where the roofing material is lost or destroyed and the roof base material such as a waterproof sheet (roofing) or a field board laid under the roofing material is exposed, together with the roofing material. It includes perforated damaged parts where holes (including gaps) are formed in the roof base material due to loss or destruction of the roof base material, or both.

Unmanned aerial vehicles (also referred to as UAVs) are aircraft, rotary-wing aircraft, gliders, and airships that cannot be boarded by humans, and can be flown by remote control or automatic control. For example, drones (multicopters). ), Radio-controlled aircraft, radio-controlled helicopters, etc. The unmanned aerial vehicle in the present invention also includes a so-called model aircraft and a small unmanned aerial vehicle having a weight of 200 g or less.

The unmanned aerial vehicle of the present invention is not particularly limited as long as it is provided with a measuring device capable of measuring the repair range including the damaged part of the roof, but the measuring device includes, for example, the roof from the sky. Examples include a camera for taking a picture, a laser measuring device, and the like, and a camera for taking a picture of the roof from the sky is preferable. Further, the unmanned aerial vehicle of the present invention preferably includes a marking device for marking the repair range of the roof and the top (building). Examples of the roof portion marked by the marking device of the present invention include a roof repair range, a roof perforated repair range, a roof top (ridge), a roof lower end (eaves), and a roof side edge (gable). ) Etc. can be mentioned.

The repair range includes at least the damaged part of the roof, and includes the part where the repair sheet is attached to the roof in addition to the damaged part of the roof.

Next, the repair sheet manufacturing step (S2) of the present invention will be described.
The repair sheet manufacturing step is a step of manufacturing a repair sheet cut into a size corresponding to the repair range. That is, the repair sheet is cut and manufactured according to the repair range including the damaged portion of the roof measured in the measurement step. The repair sheet is cut by appropriately setting it according to the position and size of the damaged part on the roof, but it is cut to a size including at least the damaged part of the roof, and is usually other than the damaged part of the roof. In addition, the part including the part where the repair sheet is attached to the roof is cut.

In the repair sheet manufacturing step, it is preferable to prepare a repair sheet having a size that can be wrapped around the lower end portion and / or the side end portion of the roof near the damaged portion of the roof. Thereby, in the repair sheet attaching step, the repair sheet can be wound and fixed around the lower end portion and / or the side end portion of the roof near the damaged portion of the roof, and the repair sheet can be easily and firmly attached.

Further, in the repair sheet manufacturing process, it is preferable to manufacture a repair sheet having a size that can be attached to the roof on the opposite slope beyond the top of the roof from the damaged portion of the roof. As a result, in the repair sheet mounting process, the repair sheet can be mounted on the roof on the opposite slope beyond the top of the roof from the damaged part of the roof, and the strong wind blowing on the roof, especially the wind from the underside of the roof, causes the repair sheet to be mounted. It is possible to prevent the repair sheet from being blown off.

Further, in the repair sheet manufacturing process, it is preferable to attach a mark to the repair sheet for attaching to the roof. The place to be marked is not particularly limited, but includes, for example, the repair range of the roof, the top of the roof (ridge), the lower end of the roof (eaves), the side edge of the roof (gable), and the like. Can be done. When markings are provided at a plurality of locations, it is preferable to mark at least one different mark. This makes it easier to align the repair sheet.

As described above, in the repair sheet manufacturing process, when the repair sheet is attached to the roof on the opposite slope beyond the top of the roof from the damaged part of the roof, a mark is placed at a position corresponding to the top of the roof of the repair sheet. It is preferable to add. As a result, when the repair sheet is attached to the roof, the repair range of the roof and the position of the repair sheet can be aligned with reference to the above mark, so that the repair sheet can be attached accurately and easily. The mark may be, for example, one point, but it is preferable that the mark is one in which the mounting direction can be easily grasped, such as a line along the top or two points along the top. Further, it is preferable to put different marks near both ends of the position corresponding to the top of the roof of the repair sheet. As a result, when the repair sheet is attached, the attachment direction can be more easily grasped.

Further, in the above measurement step, when the roof is marked by an unmanned aerial vehicle, it is preferable to mark the repair sheet with the same mark as the marking. Specifically, for example, one of the roof repair ranges is provided by the marking device. If two circles are attached to the side and one circle is attached to the other side, two circles are attached to one side of the roof repair range and one circle is attached to the other side of the repair sheet. By doing so, the alignment can be performed simply by aligning the same marks, so that the mounting direction of the repair sheet can be grasped, and the repair sheet can be mounted reliably and easily.

Next, the repair sheet attaching step (S3) of the present invention will be described.
The repair sheet attaching process is a step of attaching the repair sheet to the damaged part of the roof. As a result, the waterproofness, heat insulation, sound insulation, and airtightness of the roof can be improved. In addition, it is possible to prevent the roofing material from being blown off.
If the roof base material remains on the damaged part of the roof, the repair sheet may be directly attached on the roof base material, or a protective sheet may be provided on the roof base material and attached on the protective sheet. .. Further, when holes are formed in the roof base material (perforated damaged portion), it is preferable to provide a base sheet or foam and mount the base sheet or foam on the base sheet or foam as described later.

The repair sheet is not particularly limited as long as it can cover a damaged roof, and examples thereof include a repair sheet made of synthetic resin such as a polyethylene cloth sheet, an ester canvas sheet, and a tarpaulin canvas sheet. .. The repair sheet of the present invention is preferably an ester canvas sheet or a tarpaulin canvas sheet in terms of excellent tensile strength and weather resistance. As a result, the durability can be maintained for at least 2 to 3 years, and there is no problem even if the period until the tile roof re-roofing work is started is prolonged.

The repair sheet may be colored to match the color of the building or roofing material. If the repair sheet is colored according to the color of the building or the roofing material, the appearance of the building can be improved when the repair sheet is attached.

Examples of the method of attaching the repair sheet to the roof include a method of fixing the repair sheet to the roof using a fixing bracket and a method of fixing the repair sheet to the roof using a waterproof tape and / or a caulking agent.

Further, as described above, for a specific part, a method of wrapping a repair sheet around the lower end and / or the side end of the roof near the damaged part of the roof, or a method of fixing the damaged part of the roof beyond the top of the roof. A method of attaching a repair sheet to the roof on the opposite slope can be adopted.

As a method of fixing the repair sheet wrapped around the lower end and / or the side end of the roof, for example, a tacker (also referred to as a building stapler or a stapler) is used to fix the lower end and / or the side end of the roof. It can be fixed by striking the needle on the lower side (back side). Alternatively, it may be fixed with a waterproof tape and / or a caulking agent.

In the case of the method of fixing the repair sheet to the roof using the fixing metal fitting, the fixing metal fitting is not particularly limited as long as the repair sheet can be fixed to the roof. For example, as a fixing bracket for attaching a repair sheet to a roof of a roof tile structure, there are an inter-tile insertion part that is inserted through the repair sheet in the gap where the upper and lower tiles overlap, and an inter-tile insertion part that is located above the inter-tile insertion part. It has an upper tile holding portion that holds the repair sheet on the upper tile, and the inter-tile insertion portion and the upper tile holding portion are connected via a connecting portion, and is formed in a horizontal U-shape or a U-shape. An upper tile fixing portion and a lower tile holding portion for holding a repair sheet on the lower tile, which is provided on the opposite side of the inter-tile insertion portion of the upper tile fixing portion, can be used (FIG. 12). reference). As a result, the repair sheet can be securely fixed to the roof. In addition, the repair sheet can be attached to the roof by a simple operation of inserting the tiles into the gap created by overlapping the tiles.

The inter-tile insertion portion is preferably a rod-shaped member having an acute-angled tip. As a result, the repair sheet can be easily penetrated, and the installation becomes easy. The holes and gaps formed in the repair sheet through which the inter-tile insertion portion penetrates may be sealed with a waterproof tape or a caulking agent.

The waterproof tape is not particularly limited as long as it is waterproof and can seal holes and gaps formed at the boundary between the roof and the repair sheet, and is a sheet made of a rubber-based material or a synthetic resin-based material. Examples thereof include those in which a pressure-sensitive adhesive is applied to a similar base material. Examples of the rubber-based material include butyl rubber and silicon rubber. Further, examples of the synthetic resin-based material include polyethylene and EVA (ethylene-vinyl acetate copolymer resin).

The caulking agent is not particularly limited as long as it can seal the holes and gaps formed at the boundary between the roof and the repair sheet. For example, a urethane caulking agent, a modified silicon caulking agent, an acrylic caulking agent, and silicon. Examples thereof include caulking agents and oil-based caulking agents. The caulking agent may be used together with the waterproof tape. For example, the caulking agent may be used from above after sealing the holes and gaps formed at the boundary portion between the roof and the repair sheet with the waterproof tape.

Subsequently, a method of repairing a roof having a perforated damaged portion in which the roof base material is damaged will be described.

As shown in FIG. 2, the roof repair method of the present invention includes a measurement step (S1') for measuring using an unmanned aerial vehicle, a repair sheet manufacturing step (S2), a base sheet manufacturing step (S4), and a base sheet. It has an attachment step (S5), a foam installation step (S6), and a repair sheet attachment step (S3).

In this construction method, in the base sheet mounting step (S5) and the foam installation step (S6), the base sheet and the foam are attached to the perforated damaged portion of the roof, thereby improving the durability of the roof. be able to. In addition, since the installation of the base sheet and the foam does not require skillful techniques, even a contractor who does not specialize in roof construction, such as a contractor in a disaster area, can work.

First, the measurement step (S1') will be described.
The measurement step (S1') is a step of measuring the repair range including the damaged portion of the roof and the perforated repair range including the damaged portion of the roof using an unmanned aerial vehicle. That is, if there is a perforated damaged portion in the damaged range, not only the entire damaged portion but also the range of the perforated damaged portion is measured.

Next, since the repair sheet manufacturing step (S2) and the repair sheet attaching step (S3) are the same steps as described above, the base sheet manufacturing step (S4) will be described.
The base sheet manufacturing step is a step of manufacturing a base sheet cut to a size corresponding to the perforated repair range. That is, it is produced by cutting the base sheet according to the perforated repair range including the perforated damaged portion of the roof measured in the measuring step. The base sheet is appropriately set and cut according to the position and size of the perforated damaged portion on the roof, but is cut to a size including at least the perforated damaged portion of the roof, and the roof is damaged. In addition to the part, the part including the part where the base sheet is attached to the roof is cut.

Subsequently, the base sheet attaching step (S5) will be described.
The base sheet attaching step is a step of attaching the base sheet to the perforated damaged portion of the roof. The base sheet serves as a base material for spraying the foam material described later, prevents the foam material from adhering to the roof, and facilitates the removal of the foam.

The base sheet may be composed of only the base sheet main body, but it is preferable that the base sheet is provided with a reinforcing sheet.
The material of the base sheet body is particularly limited as long as it is made of a material that can close the holes formed in the perforated damaged portion of the roof and prevent the foaming material described later from adhering to the roof. However, for example, materials such as synthetic resin, rubber, and metal can be mentioned, and synthetic resin is preferable from the viewpoint of excellent water resistance, light weight, and ease of processing.

The base sheet body has a thin and wide shape, and preferably has a mesh. This makes it easy to carry by folding or rolling, and because it is lightweight, it is possible to work easily and safely even on the roof.

The thickness of the base sheet body is preferably 0.05 to 3.0 mm, more preferably 0.1 to 1.5 mm. The mesh size is preferably 0.1 mm to 5 mm on one side, and more preferably 0.5 mm to 2.5 mm. As a result, it is lightweight, easy to carry and work, and can prevent the foam material from adhering to the roof.

The material of the reinforcing sheet is not particularly limited as long as it is made of a material that reinforces the strength of the base sheet main body, and is preferably made of a material that is stronger than the base sheet main body. For example, synthetic resin, rubber, and metal materials can be mentioned, and synthetic resin is preferable from the viewpoint of excellent water resistance, light weight, and ease of processing.

The reinforcing sheet has a thin and wide shape, and preferably has a mesh. This makes it easy to carry by folding or rolling, and because it is lightweight, it is possible to work easily and safely even on the roof.

The thickness of the reinforcing sheet is preferably 1.0 to 10.0 mm, more preferably 2.0 to 5.0 mm. The mesh size is preferably 1.0 mm to 50 mm on one side, and more preferably 5.0 mm to 30 mm. As a result, it is lightweight and can reinforce the base sheet body. For example, it can be supported even when the worker puts his / her weight on the damaged part of the roof, such as when the worker accidentally touches the hole. And higher safety can be guaranteed.

When the base sheet is provided with a reinforcing sheet, the base sheet body may be mounted on the perforated damaged part of the roof after the reinforcing sheet is attached, or after the base sheet body is attached to the perforated damaged part of the roof. Although a reinforcing sheet may be attached on the base sheet, in the base sheet attaching step of the present invention, it is preferable to attach the base sheet main body to the perforated damaged portion of the roof and then attach the reinforcing sheet on the base sheet main body. This makes it possible to prevent the foam mounted on the base sheet from breaking.

The method of attaching the base sheet to the perforated and damaged portion of the roof is not particularly limited as long as the base sheet can be attached. For example, an attachment method using a fixture such as an adhesive or a needle. The mounting method using a needle is preferable. Specifically, a method can be used in which a base sheet covering a perforated and damaged portion of the roof is attached by hitting a needle with a tacker at a portion where there is no roofing material and the roof base material of the roof is exposed.

Further, in the process of producing the base sheet, it is preferable to add a mark for attaching to the roof to the base sheet. The place to be marked is usually any position around the perforated repair area of the roof. For example, it is preferable to mark at least one of two opposing ends of the base sheet, such as top and bottom, left and right. When markings are provided at a plurality of locations, it is preferable to mark at least one different mark. The mark may be, for example, one point, but a line, two points, or the like, which makes it easy to grasp the mounting direction, is preferable.

Further, in the above measurement step, when the roof is marked by an unmanned aerial vehicle, it is preferable to give the same mark as the marking on the base sheet. Specifically, for example, the range of repairing holes in the roof by a marking device. When two circles are attached to one side and one circle is attached to the other side, two circles are attached to one side of the perforated repair range of the roof on the base sheet and one is attached to the other side. If a circle is attached, the alignment can be performed simply by aligning the same marks, so that the mounting direction of the base sheet can be grasped, and the base sheet can be mounted reliably and easily.

Next, the foam installation step (S6) will be described.
The foam installation step is a step of spraying a foam material on a base sheet attached to a perforated damaged portion of the roof to install the foam on the base sheet. As a result, when the repair sheet is attached, the waterproofness, heat insulation, sound insulation, and airtightness of the roof can be improved. In addition, instead of installing the pre-molded foam on the roof, the foam is molded and installed by spraying it on the roof, so there is no need to adjust the size in advance and the work is not complicated, and accurate size adjustment. Is possible. Furthermore, even one person can perform the work.

The foam material is not particularly limited as long as it can form a foam on the base sheet attached to the perforated damaged portion of the roof, and examples thereof include synthetic resin foam materials and rubber foam materials. .. Examples of the synthetic resin material include an acrylic resin foam material, a polyurethane resin foam material, a polystyrene resin foam material, a phenol resin foam material, a polyvinyl chloride resin foam material, a polyolefin resin foam material, and the like. it can. Examples of the rubber foam material include urethane rubber-based foam material, ethylene propylene rubber-based foam material, acrylic rubber-based foam material, silicon rubber-based foam material, fluororubber-based foam material, and the like.

The method of spraying the foamed material is not particularly limited, and a method usually used for spraying the foamed material can be adopted. For example, a spraying method using a spraying device such as a spraying gun, a spray gun, or an airbrush. Can be adopted.

The hardness of the foam may be hard, semi-hard, or soft, but hard is preferable in terms of durability. The foam of the present invention is preferably foamed hard urethane because it is excellent in heat insulation, sound insulation and durability.

In the roof repair method of the present invention, as described above, it is preferable to attach the base sheet and the foam by spraying the foam material to the perforated damaged portion of the roof, but the roof base is attached to the perforated damaged portion of the roof.
