Description

The present invention relates to a method of installing rainproof curing for construction or repair.

Conventionally, when building or repairing various buildings such as single-family homes, apartments, condominiums, buildings and stores, if it rains, the outer walls, caulking and other building materials will get wet, and the workers themselves will get wet. There was an obstacle in the progress of work. For example, if the flooring material, which is wood, gets wet due to rain, it is necessary to stop the progress of construction work and insert additional drying work and its time for a certain period of time until it dries to a certain extent. ..

Patent Document 1 describes an invention relating to a rainproof device for a peripheral wall surface of a building provided between a building and a scaffolding frame for construction so that rain does not hit the peripheral wall surface of a building such as a building during construction. According to this document, in the conventional attachment of the tarpaulin, one side edge of the tarpaulin is fixed to the building by using a rope or the like, while the other side edge of the tarpaulin is fixed to the scaffold and mounted. The installation and removal of the waterproof sheet was extremely complicated, and the installation and removal work took a long time. Furthermore, especially the waterproof sheet causes fluttering due to wind pressure, and this fluttering causes noise, so it must be removed at all times, and when it is about to rain, a rapid waterproof sheet must be installed. There was a problem that the installation could not be dealt with promptly. In addition, when it rains or the construction is completed, the tarpaulin must be removed immediately. Even in this case, fixing means such as ropes cannot promptly respond. Such a problem is presented in Patent Document 1.

Further, in Patent Document 2, in the equipment used to cover the upper side of the building under construction and protect the building from rain, sunlight, etc., either the wind that blows up or the wind that blows without rainwater infiltrating. Further, an invention is disclosed for the purpose of providing a rainy weather curing system capable of allowing wind to escape and preventing rainwater from accumulating.

According to this document, a tent sheet fixed in a gable shape so as to cover the upper part of the building on a scaffold assembled around the building under construction, and a predetermined interval below both gables of the tent sheet. It has been proposed to provide a rainy weather curing system including an eaves tent which is vacated, stacked and fixed to the scaffold so as to be parallel to the slope direction of the tent sheet.

However, even with the proposal and disclosure of the above patent documents, the method of installing rainproof curing for construction or repair from the viewpoint of the site, which can easily prevent rain while being easy to install and remove, It cannot be said that the removal method has been thoroughly examined to the necessary and sufficient level, and there is room for further improvement and improvement. In other words, the curing for rain prevention should be called the pre-preparation stage work such as during the construction work that should be carried out, so that it can be concentrated on the original construction work etc. There is a demand for a product that is as easy to install as possible and does not overwhelm the time and man-hours. It seems that there are not many, if not many, few weather environments in Japan where there is no rainfall and there is no need to worry about getting wet for a week after the building is built.

The present invention has been made in view of the above-mentioned problems, and from the viewpoint of the site, it is easy to install and remove, and the man-hours and time for preparation thereof can be reduced. The purpose is to provide a method for installing and removing rain curing.

The method of installing the rainproof curing of the present invention is a method of installing the rainproof curing at the time of building construction in order to reduce the influence of rainfall between the wooden building and the temporary scaffold, and is an elastic rainproof at the upper end of the rafter. At the stage of locking one end of the fabric, the other end of the elastic rainproof fabric is extended and fixed to the temporary scaffold, and one end of the elastic rainproof fabric is fixed by pasting a field board on the rafters. It is characterized by having a stage and.

Further, the method for removing the rainproof curing of the present invention is a method for installing a rainproof curing for building construction in order to reduce the influence of rainfall between the wooden building and the temporary scaffold, and expands and contracts at the upper end of the rafter. A method having a step of locking one end of the rainproof fabric and a step of extending the opposite end of the elastic rainproof fabric and fixing it to a temporary scaffold and pasting and fixing a field board on a rafter. It is a method to remove the rainproof curing installed by the above, and by cutting the elastic rainproof fabric at the eaves, the remaining fabric cut to the fixed part at the upper end of the rafter is retracted so as not to be exposed on the outside. It is a feature.

Further, the method for removing the rainproof curing of the present invention is a method for removing the rainproof curing for building construction in order to reduce the influence of rainfall between the wooden building and the temporary scaffold, and is a method for removing the upper end of the rafters and the temporary construction. By cutting the elastic rainproof fabric stretched between the scaffolds at the eaves, the remaining fabric cut to the fixed part at the upper end of the rafters is retracted so as not to be exposed in appearance.

It is a figure explaining the elastic rainproof cloth in a stretched state from the viewpoint from the lower side. It is a drawing photograph corresponding to FIG. It is a drawing photograph corresponding to FIG. It is a drawing photograph corresponding to FIG.

FIG. 1A is a diagram illustrating an example of the stretchable rainproof fabric 1000 of the present embodiment. As shown in FIG. 1A, the stretchable rainproof fabric 1000 preferably has a fabric characteristic that can be pulled and stretched about 2 to 3 times in all directions. Further, in consideration of workability on the temporary scaffold, it is more preferable to keep the roll state with a width of about 500 mm to 1000 mm in a natural state. More preferably, the workability is most improved by setting the width to 500 mm to 600 mm in the natural state.

In reality, when the stretchable rainproof fabric 1000 is stretched on the temporary scaffolding, the stretchable rainproof fabric 1000 is stretched and rolled in sequence according to the distance between the upper end of the rafters and the temporary scaffolding. The work of locking and fixing while rolling and pulling out the dough will be performed.

The distance between the eaves of a built house or the like and the temporary scaffolding may differ greatly depending on the location even within the same house, depending on the structure of the house, the floor plan, the protruding width of the balcony, and the like. In particular, balconies often have an uneven structure with different protrusion widths on the way. In such a case, it is complicated to prepare rainproof curing with different widths (does not expand and contract) in advance, and to carry out the work of separately stretching according to each installation width, and the number of parts and the number of parts are increased. The work process also increases and becomes complicated. Generally, the distance between the temporary scaffolding and the upper end of the rafters when constructing a wooden house is within the range of 1 m to 3 m, and even in the same house, the distance varies depending on the location, orientation, floor plan structure, installation mode of the temporary scaffolding, etc. It is often quite different. For this reason, the present invention has versatility that can flexibly respond on-site (on the spot) regardless of the width to be rain-cured without preparing a plurality of rain-curing sheets having different widths in advance. Rain curing is also extremely convenient. Further, the rainproof curing of the present invention makes it possible to install a rain curing so as to prevent leakage by flexibly closing the gap even in the corner portion of the building, which was difficult in the past.

By using the stretchable rainproof fabric 1000 of the present invention, even different parts having different tension intervals in the same building can be flexibly dealt with by appropriately pulling and stretching. Therefore, it is not necessary to individually prepare rainproof fabrics having different widths in advance, and it is possible to continue the stretching work as it is even in the parts having different intervals, so that the workability is extremely good. ..

In addition, at the joint between the gable area (keraba) and the eaves, that is, at the corner of the building, it is necessary to coordinate rainproof curing in both directions so that a continuous rainproof effect can be obtained, but it is elastic. By appropriately adjusting the degree of pulling of the rainproof cloth 1000, it is possible to easily cooperate with each other so as not to generate a gap.

Further, for example, when trying to use a rainproof curing cloth having a width of about 1.8 m in a natural state from the beginning, workability on a narrow temporary scaffold is extremely poor. It is not easy to lift a member having such a large width and length on a temporary scaffold, deploy it on the temporary scaffold, and fix it on a stretch. That is, the upper space of the temporary scaffolding in the state after the building is raised has a certain length because many structural members such as houses and scaffolding support materials are complicatedly present and the effective workable space is extremely limited. It is inconvenient to handle members with a sheath width.

As can be understood from the above description, the stretchable rainproof fabric 1000 is preferably configured to be stretchable at least several times in the width direction (width direction shown as 500 mm to 1000 mm shown in FIG. 1). Further, it is more preferable that the roll can be expanded and contracted several times in the length direction (the length direction in which the roll shown in FIG. 1 is rotated and opened and pulled out). Further, it can be understood that it is more preferable that the structure is stretchable by several times even in the remaining diagonal direction.

The preferable stretch characteristics of the stretchable rainproof fabric 1000 are as described above, but the fabric having the property of being stretchable by pulling is heat insulating underwear, sports tights, UV cut fabric, UV cut arm cover (arm cover) and the like. , Various known stretch fabrics and fabrics obtained by arranging them for construction (typically increasing the thickness and increasing the strength) can be used. A waterproof / water-repellent function may be added to such a fabric. Further, a rubber sheet, a mesh sheet, or the like can also be used. However, the material, features, form, etc. of the stretchable rainproof fabric 1000 are not limited to the above description as a typical example, and any material or the like may be used.

Further, the stretchable rainproof fabric may be a hydrophilic fabric that gently guides rainwater from the inside and outside of the fabric to the curing sheet on the outside of the scaffold, or may be a water-repellent fabric. Even if it is a hydrophilic fabric, if it rains a little, it is possible to sufficiently prevent the flooring material and the like from getting wet by transmitting rainwater through the inside and outside of the fabric and guiding it to the outside. For example, in order to guide rainwater more smoothly, the stretchable rainproof fabric may be made so that the main constituent fibers are oriented in the same direction from the upper end side of the rafters to the temporary scaffold side, and it is stretched as such. May be. For example, in the installed state of the elastic rainproof fabric, the fabric should be stretched so that the movement resistance of water between the upper end of the rafters and the temporary scaffolding is smaller than the movement resistance of water in the direction perpendicular to it. Can be done. With the stretchable rainproof fabric stretched, it is possible to paint the gable board and fascia, install the rain gutter, etc., and it does not interfere with the work.

Further, FIG. 1B is a diagram illustrating a state in which the stretchable rainproof fabric 1000 of the present embodiment is stretched on the upper end of the rafters 1110 of the building 1100 as a typical example. In FIG. 1 (b), the description of the temporary scaffolding is omitted for convenience of explanation, but in the actual stretching scene, the space between the upper end of the rafters 1110 and the temporary scaffolding (not shown) is provided in the entire circumference of the building 1100. , The stretchable rainproof fabric 1000 will be stretched. 1111 is the upper end of the keraba rafters, and 1112 is the upper end of the eaves rafters.

As shown in FIG. 1 (b), by providing the stretchable rainproof fabric 1000, flooring materials, pillar materials, other building / repair members, base materials / structural materials due to rainfall during subsequent construction work, etc. Can be prevented from getting damp or wet, including workers.

Further, FIG. 1 (c) is a diagram illustrating a state in which the stretchable rainproof cloth 1000 is stretched in a state where the temporary scaffolding 1200 is installed around the building 1100 shown in FIG. 1 (b). As shown in FIG. 1 (c), it is preferable that one end of the stretchable rainproof fabric 1000 is locked to a handrail portion of the temporary scaffold 1200 arranged in the horizontal direction, if possible. This makes it possible to arrange an orderly eaves in line with the horizontal eaves. On the other hand, there may be cases where horizontal handrails do not exist or do not match at gable points where the height gradually differs in the diagonal direction, the connection part between the eaves and the connection part, and the connection part with different balcony widths. One end of the elastic rainproof fabric 1000 may be locked to an arbitrary portion of the temporary scaffold 1200.

FIG. 2A is a side view for explaining a typical example in which the stretchable rainproof cloth 1000 is stretched between the temporary scaffolding 1200 around the building 1100 and the upper end of the eaves rafters. In FIG. 2A, a field board (roof base material) 1120 is fixedly attached onto the rafters 1110, and when the field board 1120 is fixed by a fixing member such as a nail, the elastic rainproof fabric 1000 is attached to the eaves tip rafters. It is fixed in a state of being sandwiched between the upper end and the field board 1120.

For this reason, the stretchable rainproof fabric 1000 may be temporarily fixed to the upper end of the eaves rafters, for example, with a curing tape or the like until the field board 1120 is attached, and it expands and contracts at the same time when the field board 1120 is nailed and fixed. The rainproof cloth 1000 may be sandwiched and fixed by nailing. Further, as shown in FIG. 2A, it is also possible to provide elastic rainproof fabrics 1000 (2) and 1000 (1) at the eaves on the first floor and the second floor, respectively.

Further, as shown in FIG. 2A, the elastic rainproof fabric 1000 can transmit rainwater to the upper end of the eaves rafters at one end and to a curing sheet (not shown) provided at the other end on the outer surface of the temporary scaffold 1200. It is connected to the extent. As a result, the rainwater that has passed down the stretchable rainproof fabric 1000 can smoothly flow down to the curing sheet and quietly flow down from the curing sheet to the ground or a height position close to the ground without splashing water.

Further, as shown in FIG. 2A, the width interval h to be covered by the elastic rainproof fabric 1000 is not only different for each building, but also the surrounding conditions, structure, balcony width, and eaves even in the same building. There are many cases where the difference is considerably large depending on the balconies or the status of securing a safe temporary scaffolding installation position. By using the stretchable rainproof fabric 1000 shown in the present embodiment, it is possible to flexibly respond by appropriately pulling and stretching in the field conditions of different width intervals.

For example, even if the roll-shaped stretchable rainproof fabric 1000 having a width of 600 mm in a natural state can be pulled in the width direction, a rainproof curing can be stretched on a balcony having a width interval h = 1200 mm. Then, even if the balcony is expanded to a wide width from the middle to, for example, a width interval h = 1800 mm, it is possible to adjust the degree of pulling expansion and contraction.

Then, for example, a scroll-shaped elastic rainproof fabric 1000 having a width of 750 mm in a natural state and a scroll-shaped elastic rainproof fabric 1000 having a width of 1000 mm in a natural state can be similarly applied. In general, the width required for such rainproof curing is often about 1000 mm or more. Therefore, by setting the stretchable rainproof fabric 1000 in a roll state with a width of about 500 to 1000 mm in the natural state, many It can be applied in the field and workability is improved.

Further, by making the inclination angles of the field board 1120 and the elastic rainproof fabric 1000 substantially the same as shown in FIG. 2A and making them substantially flush with each other, rainwater can be transmitted more smoothly. It is preferable. However, the present invention is not limited to this, and the rainfall on the field board 1120 and the rain on the elastic rainproof fabric 1000 are both smoothly transmitted to the temporary scaffold 1200 side and do not impair the function of flowing down. Each can be arranged at any inclination angle.

If the resistance of the water transmitted through the elastic rainproof fabric 1000 is large, the inclination of the elastic rainproof fabric 1000 is increased, and if the resistance of the water transmitted through the elastic rainproof fabric 1000 is not large, the elastic rainproof fabric 1000 is increased. The slope of 1000 can be reduced. Therefore, it is more preferable that the water movement resistance in the width direction of the stretchable rainproof cloth 1000 shown in FIG. 1A is smaller than the water movement resistance in the length direction (roll winding direction). For example, the time it takes for a vertically held fabric to reach the lower end at regular intervals with plenty of water from the top, that is, the movement resistance of water, is the material, thickness, knitting method, and composition of the fabric.・ It varies greatly depending on the structure and characteristics. When the stretchable rainproof fabric 1000 is configured to transmit water in such a state of containing water, it corresponds to the direction from the field board 1120 to the temporary scaffold 1200, typically FIG. 1 (a). ), The transmission resistance in the width direction of the roll mode is set to be smaller than the transmission direction in the length direction, so that the water can be more smoothly conducted from the field board 1120 to the temporary scaffold 1200. However, this is only an example, and even if the stretchable rainproof fabric 1000 is made of a fabric having, for example, a water-repellent property that does not have a water-permeable property (or a water-containing property), the upper surface thereof is repelled and flows down. good.

Further, FIG. 2B is a diagram illustrating a fixing jig 2000 as a typical example for fixing and locking the stretchable rainproof cloth 1000 to the handrail of the temporary scaffold 1200. As shown in FIG. 2B, the fixing jig 2000 includes a C-shaped hook 2100 for hooking on the temporary scaffold 1200. Further, as can be understood from FIG. 2B, the fixing jig 2000 is provided with an uneven structure for sandwiching and sandwiching the stretchable rainproof cloth 1000 in an extended state in which the stretchable rainproof cloth 1000 is pulled.

In the uneven structure, rubber members a, b, c, and d, which are non-slip friction materials, are adopted at the contact points at two places where they come into pressure contact with the elastic rainproof fabric 1000, and a large static friction force is adopted. Therefore, the stretchable rainproof fabric 1000 can be pressed and held. FIG. 2B shows, as an example, a configuration in which an uneven structure opens in the vertical direction to form an opening, and the elastic rainproof fabric 1000 is sandwiched and closed to hold the fabric.

Then, the concave-convex structure in a closed state sandwiching the fabric 1000 is locked by rotating the hook 2100, and the hook 2100 is hung on the scaffolding material 1200 while being pulled from the elastic rainproof fabric 1000. As long as there is a positional relationship, the state of holding the dough by closing it so as not to open the opening is maintained. Further, when the concave-convex structure is opened to remove the fabric, the hook 2100 can be rotated in the opposite direction so that the obex can be disengaged from the hole 2200 and unlocked.

Further, it is preferable that the upper portion of the fixing jig 2000 is inclined downward to such an extent that water smoothly flows from the stretchable rainproof fabric 1000 side to the opposite side thereof in the use and installation state. A curing sheet is stretched on the opposite side, and it is preferable that rainwater is smoothly transmitted to the upper part of the fixing jig 2000 from the stretchable rainproof cloth 1000 to the curing sheet. The fixing jig 2000 as illustrated in FIG. 2B is not limited to a mode in which the upper surface is a flat surface, but as its function, it can provide a smooth flow path without repelling water to the surroundings. By doing so, it is possible to prevent the surrounding water from getting wet and damp due to water splashing, the generation of mold, and the deterioration of water content of the member.

It should be noted that many variations of such a fabric holding mechanism and holding structure, including a locking and unlocking mechanism, are already known and realized, so that any structure, composition, or material can be used. It is possible to use the one as appropriate, and the one having the configuration shown in FIG. 2B described above is merely an example and is not limited thereto.

Further, FIG. 3 is a diagram illustrating a state in which the elastic rainproof fabric 1000 is temporarily fixed to the upper end of the eaves rafter, which is the upper end of the tip of the rafter 1110 of the building 1100 that has been raised. As can be seen from FIG. 3, in the narrow and intricate work space formed between the temporary scaffold 1200, the drop clothes 1300 stretched on its outer surface, and the building 1100 under construction or repair, the book The stretchable rainproof fabric 1000 as described in the embodiment is extremely useful and can be effectively utilized to provide extremely great merits in improving workability and work efficiency.

In FIG. 4, a field board 1120 is attached and fixed on the rafters 1110 after one end of the elastic rainproof fabric 1000 is temporarily fixed to the upper end of the eaves rafters, and the other end of the elastic rainproof fabric 1000 is attached to the temporary scaffold 1200. It is a figure explaining the locked state. As shown in FIG. 4, the slope is configured so that rainwater can smoothly move from the field board 1120 to the curing sheet 1300 by transmitting the elastic rainproof fabric 1000 down. In FIG. 4, for example, the inclination of the field board 1120 and the inclination of the stretchable rainproof cloth 1000 may be set to be the same and substantially flush with each other. Further, for example, by contacting the other end of the stretchable rainproof cloth 1000 with the curing sheet 1300, rainwater may be transmitted from the stretchable rainproof cloth 1000 to the curing sheet 1300 via the contact portion.

Further, FIG. 5 is a diagram illustrating the stretchable rainproof fabric 1000 in a stretched state from a viewpoint from below. When the need for rainproof measures is eliminated and the elastic rainproof fabric 1000 is removed, cut with a cutter or the like at the end of the field board 1120, that is, the left end portion of the elastic rainproof fabric 1000 exposed in FIG. As a result, based on the stretch characteristics of the stretchable rainproof fabric 1000, the exposed portion is automatically withdrawn by being drawn to the upper end of the rafters below the field board 1120. Even if the roofing material is already installed on the field board 1120, it shrinks into a slight gap between the field board and the upper end of the rafters and is pulled in and withdrawn.

The pieces of the elastic rainproof fabric 1000 fixed to the upper end of the rafters (the part that has been shrunk and removed) are not apparently observed, and even if they remain as they are, they do not have any adverse effect on the structure of the building. do not have. Further, the remaining portion of the stretchable rainproof fabric 1000 cut out can be reused for the next rainproof curing. Although the fabric is cut off and has a slightly narrow width interval, it can be reused within that range because it is pulled and stretched to a certain extent based on its expansion and contraction characteristics. Note that FIG. 5 shows an example in which the stretchable rainproof fabric 1000 is directly fixedly locked to the temporary scaffold 1200 without using the fixing jig 2000, but the method and mode of the fixed locking are as follows. It is optional as long as rainwater can be transmitted smoothly.

The method of installing the rainproof curing of the present invention is a method of installing the rainproof curing for building construction in order to reduce the influence of rainfall between the wooden building and the temporary scaffold, and is an elastic protection at the upper end of the hanging tree. At the stage of locking one end of the rain cloth, and extending the other end of the stretchable rainproof cloth to fix it to the temporary scaffold, and sticking a field board on the rafter to fix one end of the stretchable rainproof cloth. It is characterized by having a stage to be used.

As a result, installation work and repair work of the outer wall material can be done without getting wet with people and materials, caulking and work are possible, and flooring and pillar materials until the outer wall is installed after the building is raised. Can prevent mold from being moistened or moistened. Either extending the other end of the stretchable rainproof fabric and fixing it to the temporary scaffolding, or pasting a field board on the rafters to fix one end of the stretchable rainproof fabric first. You may do this, but by sticking the field board to the rafters with nails etc., the stretchable rainproof fabric located in the lower layer will also be firmly fixed with the nails etc., so the subsequent elasticity It is preferable that the work of extending the other end of the rainproof cloth and fixing it to the temporary scaffold can be performed more stably and easily.

Further, either one of locking one end of the elastic rainproof fabric to the upper end of the rafters and fixing the other end of the elastic rainproof fabric to the temporary scaffolding may be executed first. Since the fabric is also fixed by temporarily fixing the fabric to the upper end of the rafters and then pasting the field board, it is necessary to temporarily fix one end of the elastic rainproof fabric to the upper end of the rafters first. It is more preferable to use a field board to fix the main board and finally fix the other end to the temporary scaffolding, because the work can be performed more stably.

By attaching one side of the elastic rainproof fabric of the present invention to the upper end of the existing rafters, it does not interfere with other construction work, and it is smooth and short while ensuring ease of removal. It will be possible to complete the rainproof curing in time. Further, since the other side of the elastic rainproof fabric is fixed to the existing temporary scaffold (more preferably, its handrail), it is not necessary to provide a separate dedicated support rod or the like, and it is efficient and lightweight. Further, the scaffolding may be adjustable by appropriately adjusting the mounting height position to the temporary scaffolding in consideration of ensuring a sufficient working space for the worker.

Further, the method for installing the rainproof curing of the present invention is preferably characterized in that the position of the temporary scaffold to which the other end of the stretchable rainproof fabric is fixed is lower than the height of the upper end of the rafters. As a result, rainwater smoothly flows down the fabric from the height of the upper end of the rafters to the locked portion of the temporary scaffolding due to gravity. In addition, the stretchable rainproof fabric has the effect that the fabric is held diagonally in a pulled state with moderate tension with almost no slack in the middle, and there is a concern that rainwater will drip in the middle of the fabric. Can be reduced.

Further, the method for installing the rainproof curing according to the present invention is further preferably characterized in that a curing sheet is provided on the outer surface of the temporary scaffold. Further, in the method of installing the rainproof curing of the present invention, more preferably, the elastic rainproof fabric and the curing sheet can move with water so that rainwater flows from the elastic rainproof fabric to the curing sheet and falls downward. It is characterized by being connected to each other.

In order to guide the rainwater to the ground more effectively and quietly, it is preferable to use a mode in which the rainwater is transmitted downward along the curing sheet attached to the outer surface of the temporary scaffold. Since the curing sheet is usually locked and fixed to the temporary scaffolding as a technical common sense of those skilled in the art, rainwater flows to the curing sheet along the elastic rainproof fabric which is also locked and fixed to the temporary scaffolding. It will be possible.

Further, the method for installing the rainproof curing according to the present invention is further preferably characterized in that the installation of the rainproof curing is carried out on the day of building up. Risks such as getting wet due to rainfall occur immediately after the building is built. In addition, whether it will rain or not, and when it will rain, how much it will rain, will vary greatly depending on the season, place, time, etc., and we will coordinate with the progress of construction work at the time of construction. That is a difficult task. Therefore, in order to reduce the risk of inconvenience due to rainfall as much as possible and obtain the maximum quality deterioration prevention effect after building up, if possible immediately after building up, install the above-mentioned rainproof curing on the same day. Can be said to be preferable.

Further, the installation method of the rainproof curing of the present invention is further preferably characterized in that the stretchable rainproof fabric is installed substantially flush with the field board. When it rains on the elastic rainproof fabric, it naturally rains on the field board (or the tarpaulin placed on it, etc.) adjacent to it, and the rain falls. Normally, it will run down on the field board and flow down. For this reason, it is installed almost flush with each other so that the rainwater from the field board will fall down quietly without splashing, and will smoothly flow and move on the elastic rainproof fabric with little resistance. Is even more preferable.

Further, the installation method of the rainproof curing of the present invention is further preferably characterized in that the stretchable rainproof fabric is installed in a state of being stretched 2 to 3 times in at least one direction from the natural state. do. As a result, the fabric can be held and stretched in a pulled state in which the expansion and contraction characteristics of the fabric are fully utilized. In addition, since it is in a state of being small and degenerate without stretching in a natural state during storage and transportation, it is easy to carry and the storage place is not bulky, which is a great merit. Furthermore, even for variations in which the intervals to be stretched differ variously, the elongation ratio can be slightly changed only by appropriately adjusting the tensile strength, so that the applicable range can be extremely wide. However, in actual use, the degree of elongation of the fabric may be adjusted by pulling it appropriately according to the construction distance at the site, so it is not a property that it can be used only two to three times as typical as a typical example. That is clear.

Further, in the method of installing the rainproof curing of the present invention, more preferably, the elastic rainproof fabric is a stretchable rainproof fabric fixed to the upper end of the keraba rafters and an elastic rainproof fabric fixed to the upper end of the eaves rafters. It is characterized in that the elongation rates are different from each other. The stretchable rainproof fabric of the present embodiment can flexibly correspond to various intervals, shapes and modes between the upper end of the rafters and the temporary scaffolding by appropriately adjusting the degree of elongation, that is, only by appropriately adjusting the degree of tension. It can be stretched. Typically, the distance to the temporary scaffolding is often different between the upper end of the eaves rafters and the upper end of the keraba rafters where the gable board etc. will be located, but the elastic rainproof fabric has a pulling force. It is possible to stretch it larger and wider just by adjusting it, so there is no need to prepare other rainproof fabrics of different widths.

Further, the method for installing the rainproof curing of the present invention is further preferably characterized in that a stretchable rainproof fabric is provided around the entire circumference of the wooden building. As a result, for example, the rainproof effect on the entire building including the balcony can be more appropriately exhibited, and it becomes possible to further contribute to the improvement of quality.

Further, in the method of installing the rainproof curing of the present invention, more preferably, at the stage of locking one end of the elastic rainproof fabric to the upper end of the rafters, the elastic rainproof fabric held in a roll shape in a non-stretchable state is provided. It is characterized in that it is sequentially locked while being rotated to release the roll. By using the stretchable rainproof fabric in such a mode, it is compact and easy to carry during storage, but it is relatively narrow when the stretchable rainproof fabric is stretched, and there are various obstacles. It is relatively easy to pull out the dough and temporarily fix it while rotating the roll along the upper end of the rafters.

Further, in the method for removing the rainproof curing of the present invention, preferably, the elastic rainproof fabric installed by the above-mentioned installation method of the rainproof curing is cut at the eaves to fix the upper end of the rafters so as not to be exposed in appearance. It is characterized by degenerating the residual dough cut to a portion. Further, the method for removing the rainproof curing of the present invention is a method for removing the rainproof curing for building construction in order to reduce the influence of rainfall between the wooden building and the temporary scaffold, and is a method for removing the upper end of the rafters and the temporary construction. By cutting the elastic rainproof fabric stretched between the scaffolds at the eaves, the remaining fabric cut to the fixed part at the upper end of the rafters is retracted so as not to be exposed in appearance. This makes it extremely easy to withdraw the stretchable rainproof fabric. In the vicinity of the boundary where the stretchable rainproof fabric is exposed at the eaves or gable, for example, just by cutting with a cutter, the fabric that was pulled and stretched shrinks to the natural state and is pulled into the lower part of the field board. Will be. Since the elastic rainproof fabric is also fixed and locked to the nails and the like when fixing the field board, the fabric shrinks toward the fixed position and becomes invisible from the outside.

Further, the elastic rainproof fabric fixing jig of the present invention is the elastic rainproof fabric fixing jig used by the method described above, and the hook for locking to the temporary scaffold and the hook rotate. It is equipped with a concavo-convex structure that can be mounted and holds the stretchable rainproof fabric in a stretched state, and the hook is configured to lock the pinched state of the concavo-convex structure by rotating. And. As a result, the stretchable rainproof fabric can be easily fixed in a state of being pulled on the temporary scaffolding. In addition, since there is almost no concern that the stretchable rainproof fabric will be damaged or damaged by this fixing jig, the possibility that the fabric can be reused can be increased.

Further, in the fixing jig of the stretchable rainproof fabric of the present invention, preferably, the stretchable rainproof fabric and the uneven structure are contact-fixed with a non-slip rubber member at at least two places in the pulling direction. It is a feature. The material can be pressed and fixed without being damaged by the frictional force of the rubber member, and can be reliably stopped at two or more places.

Further, the fixing jig of the stretchable rainproof fabric of the present invention is further preferably characterized in that two or more hooks are provided along the longitudinal direction of the concave-convex structure. The uneven structure can have a certain length in the length direction of the eaves (or the length direction of the handrail of the temporary scaffold), but even in such a case, it is stably and more reliably temporarily installed by a plurality of hooks. Can be locked to the scaffold.

Further, the fixing jig of the elastic rainproof fabric of the present invention is more preferably in a state where the hook is locked to the temporary scaffold, and the upper surface of the concave-convex structure is from a position where the elastic rainproof fabric is fixedly arranged. It is characterized by having a slope that becomes lower toward the opposite side.

As a result, the rainwater that travels through the stretchable rainproof fabric travels along the upper surface of the jig and flows smoothly to the curing sheet on the outer surface of the temporary scaffold without splashing, forming a stretchable rainwater path. Rainproof fabric → Fixing jig → Drop clothes → Rainwater can be effectively discharged to the ground. In addition, if rainwater temporarily stays on or around the jig, it will be in a so-called puddle state, and when removing the water, there will be a concern about water splashing again. Such concerns can be dispelled. Therefore, it is possible to further reduce the concern that the floor material gets wet with rainwater, water splashes, etc., and it is possible to save the work of drying the floor material and the waiting time until the drying is completed, and the work efficiency is improved.

In addition, if the roofing material on the field board has already been placed or the rain gutter has already been installed in the fascia when repairing the building or house, use a fixing jig to lock the rain gutter (support the rain gutter). It is also possible to hook the hook 2100 on the pin) to fix and lock the elastic rainproof fabric. In this case, as an example, it is not necessary to stretch the elastic rainproof cloth on the side surface where the gable board is present, or it may be stretched by using a separate locking tool or the like. It may be stretched only in various places.

The rainproof curing during construction, etc. according to the above description is not limited to the description in the embodiment, and the configuration, structure, material, and method may be appropriately configured within the scope of the object of the present invention and within the range obvious to those skilled in the art. It can be changed and arranged. For example, a gable roof is known as a typical residential roof shape, but the present invention can also be applied to a one-way roof, a hipped roof, or a square roof. In addition, the upper end of the rafters in this document is a concept including the upper end of the keraba rafters and the upper end of the eaves rafters, and also includes all other upper ends of the rafters.
