Description

  The present invention relates to a scaffold member for a slate roof and a method for installing the scaffold member, and in particular, a scaffold member for a slate roof and a scaffold member installed for use in maintenance / inspection or repair of a slate roof or a wall portion adjacent to the slate roof. Regarding the method.

  It is known to use a slate roof that is covered with a slate as a roof of a main building such as a factory or a warehouse. Since slate roofs deteriorate over time, it is necessary to perform regular maintenance and inspections and repairs as necessary.

  Maintenance, inspection and repair of the slate roof are performed, for example, after providing a temporary scaffolding plate on the slate roof. However, a temporary scaffold board may be formed, for example, only by placing a long board serving as a scaffold board on a slate roof, which may not always be safe. Therefore, it is not always possible to secure safety simply by installing a temporary scaffolding board, and there is a possibility that a fall accident or the like may occur due to stepping. Moreover, in order to cope with such a fall, it was necessary to put a safety net inside the purlin etc., which was very troublesome.

  Thus, when working on a slate roof, it has been difficult to ensure the safety of workers. Therefore, various techniques relating to a scaffold installed on the slate roof have been considered in order to perform work safely on the slate roof.

  For example, Patent Document 1 describes a construction scaffold plate that is used by being placed on a roof in which corrugated roof members are overlapped with each other and laid in a continuous manner, and the overlapping portion is fixed with fixing bolts. Yes. Specifically, in Patent Document 1, any one of a pair of scaffolding plate main bodies having a long hole for positioning a fixing bolt between adjacent portions, a closing material that closes both ends of the scaffolding plate main body, and the scaffolding plate main body. A roof construction scaffolding board having a lifeline attachment / use handle provided on one outer surface is described. According to Patent Document 1, the above-described configuration makes it possible to secure a worker's scaffolding, and to ensure the safety of the worker when working or walking on the roof.

  Further, for example, in Patent Document 2, a support steel pipe disposed in a corrugated concave portion on a slate roof and disposed so as to protrude from the corrugated convex portion, and a scaffold having a predetermined area equipped by being coupled to the support steel pipe A slate rooftop equipment inspection deck consisting of plates is described. According to Patent Document 2, with the above configuration, it is possible to transmit the load in maintenance work to the slate roof on an average via the support steel pipe. As a result, according to Patent Document 2, it is possible to perform maintenance and repair at low cost without damaging the slate roof.

Japanese Utility Model Publication No. 63-140444 JP 2003-13573 A

  In the case of the technique described in Patent Document 1, the pair of scaffold board main bodies forms a long hole by welding a spacer between the pair of scaffold board main bodies. Thus, since a pair of scaffold board main body is welded beforehand, when installing a construction scaffold board on a slate roof, it is necessary to carry a pair of scaffold board main body at once. As a result, the weight required to be carried on the roof at a time increases, which may make it difficult to install the scaffolding board on the slate roof.

  Moreover, in the case of the technique described in Patent Document 2, the locking pins provided on the scaffolding plate are attached to the long holes provided at predetermined intervals in the extending direction of the conduit tube which is the support steel pipe. Then, the scaffolding board will be laid in order from the bottom. Because of this configuration, it took a lot of work to install the equipment inspection deck on the slate roof above the slate roof. In other words, even if the technique of Patent Document 2 is used, it is difficult to install the scaffolding board on the slate roof by an easy method.

  Thus, the problem that it was difficult to install a scaffolding board by an easy method on the slate roof has arisen.

  Then, the objective of this invention is providing the scaffold member for slate roofs which can solve the problem that it is difficult to install a scaffold board by an easy method on a slate roof.

  1st Embodiment of this invention demonstrates the scaffold member 1 for slate roofs installed on a slate roof. A slate roof is a roof that is often installed in factories and the like, and is formed by, for example, fixing a slate arranged on an aggregate constituting a purlin of a factory or the like with a fixture such as a bolt or a nut. ing. The slate roof scaffold member 1 according to the present embodiment is installed at a predetermined position on the slate roof when it is necessary to move on the slate roof, such as when the slate roof is maintained / inspected or repaired. As will be described later, the slate roof scaffold member 1 described in the present embodiment includes a scaffold plate frame 2 and a scaffold plate 3, and can be carried separately and in an easy manner on the slate roof. The slate roof scaffold member 1 (scaffold plate frame 2 and scaffold plate 3) can be installed. By configuring the slate roof scaffold member 1 in this way, it is possible to install the scaffold plate in an easy manner on the slate roof.

  In addition, for example, when the first floor roof is a slate roof, it may be necessary to maintain, inspect and repair the wall of the main building corresponding to the second floor (a slate roof of two or more floors may be used). ). In this way, when maintaining, inspecting, and repairing a wall adjacent to a slate roof, sufficient maintenance, inspection, repair, etc. are performed depending on the height of the wall, etc., only by being able to safely move on the slate roof. There is a risk that it may not be possible, and it may be difficult to ensure safety. In order to cope with such a fear, as will be described later, the slate roof scaffolding member 1 according to the present embodiment is configured so that the slate roof scaffolding member 1 can be installed with a sillboard frame 4 and a wooden sillboard 5. Yes. By using the bottom plate frame 4 and the bottom plate 5, the scaffold 11 can be assembled on the slate roof scaffold member 1. In other words, when the scaffold is assembled, it is necessary to nail the jack base to the floor board in order to prevent the scaffold from sliding or sinking. According to the slate roof scaffold member 1 in this embodiment, the floor board frame 4 Since the wooden base plate 5 is provided, the jack base can be nailed to the base plate 5 on the slate roof, and the scaffold 11 can be safely assembled on the slate roof by an easy method. As a result, it becomes possible to maintain, inspect and repair the wall of the part corresponding to the second floor of the main building safely and easily by an easy method.

  FIG. 1 is a diagram illustrating an example of a usage state of a slate roof scaffold member 1 described in the present embodiment. Referring to FIG. 1, it can be seen that the slate roof scaffold member 1 is installed on the slate roof and the scaffold 11 is assembled on the slate roof scaffold member 1. Thus, when the slate roof scaffold member 1 in this embodiment is used, the scaffold 11 can be safely assembled on the slate roof.

  FIG. 2 is a perspective view showing an example of the configuration of the slate roof scaffold member 1, and FIG. 3 is an exploded view showing an example of each configuration constituting the slate roof scaffold member 1. Referring to FIGS. 2 and 3, the slate roof scaffold member 1 includes a scaffold plate frame 2, a scaffold plate 3, a bottom plate frame 4, a bottom plate 5, and a handrail 6.

  In the present embodiment, the side on which the floor plate 5 is located when viewed from the scaffold plate 3 in FIG. 2 is defined as the upper side and will be described. Therefore, for example, in the case of FIG. 2, the base plate frame 4 is installed on the scaffold plate frame 2. For example, in the case of FIG. 1, the slate roof scaffold member 1 is installed on the slate roof, and the scaffold 11 is assembled on the floor plate 5.

  The scaffold plate frame 2 (frame portion) is a metal member such as aluminum or steel, and has a substantially rectangular shape in plan view. The scaffold plate frame 2 has, for example, a length in the longitudinal direction of about 2 m and a length in the short direction of about 0.8 m (the size may be other than the illustrated size). Referring to FIG. 4, the scaffold plate frame 2 includes, for example, a pair of square pipes 21 (may be C-type steel pipes), a pair of angles 22 (L-shaped steel) that connect the pair of square pipes 21, and a pair The under bar 23 for connecting the square pipe 21 and the handrail mounting hole 24 are configured.

  Specifically, the angle 22 which connects the edge parts of the pair of square pipes 21 is welded to both ends of the pair of square pipes 21 so as to face each other. In other words, the angle 22 is a pair of L-shaped surfaces constituting the angle 22, one surface being located at the end of the pair of square pipes 21, and the other surface being paired from below the surface on the end side. It is welded to the end part of a pair of square pipe 21 in the state arrange | positioned so that it may extend to the side by which this square pipe 21 is arrange | positioned. With such a configuration, the surface of the angle 22 that extends from below the surface on the end side supports the scaffold plate 3 from below when the scaffold plate 3 is placed inside the scaffold plate frame 2. It will function as a support part (end part support part). The pair of square pipes 21 and the angles 22 welded to both ends of the pair of square pipes 21 form a substantially rectangular shape in plan view. The side surfaces (side wall portions) of the square pipes 21 and the angles 22 are formed. The frame part which surrounds the circumference | surroundings by the surface of the edge part side is formed.

  For example, two auxiliary pieces 221 are formed on a surface of the angle 22 that functions as a support portion (that is, a surface extending from below the surface on the end portion side). The auxiliary pieces 221 are formed at positions corresponding to the width of the scaffold plate 3 (at intervals corresponding to the length of the scaffold plate 3 in the short direction), and define the place where the scaffold plate 3 is placed. Assist the placement of The scaffold plate 3 in the present embodiment is placed on the surface of the angle 22 that functions as a support portion and at a position defined by the auxiliary piece 221. For example, in the case of the present embodiment, as shown in FIGS. 2 and 3, three scaffold plates 3 are placed inside the scaffold plate frame 2. For example, one of the three scaffold plates 3 is placed between one square pipe 21 and the auxiliary piece 221, and the other is placed between the auxiliary piece 221 and the auxiliary piece 221. Is placed between the other square pipe 21 and the auxiliary piece 221. By forming the auxiliary piece 221 on the surface of the angle 22 that functions as a support portion, the scaffold plate 3 can be easily arranged and the scaffold plate 3 can be prevented from being displaced. .

  The pair of square pipes 21 are connected by the angle 22 as described above, and are also connected by the under bar 23 (intermediate support portion). The under bar 23 is formed, for example, in the middle between one angle 22 welded to both ends of the pair of square pipes 21 and the other angle 22. Although FIG. 4 illustrates the case where one under bar 23 is welded between one angle 22 and the other angle 22, for example, two under bars 23 are provided between the one angle 22 and the other angle 22. A plurality of under bars 23 may be formed.

  The underbar 23 is welded to the square pipe 21 so as to be positioned at the same height as the surface of the angle 22 that functions as a support portion. With such a configuration, the underbar 23 functions as a support part that supports the scaffold plate 3 from below when the scaffold plate 3 is placed inside the scaffold plate frame 2, as with the angle 22. .

  It should be noted that the angle 22 and the under bar 23 are a pair of corners that are adjusted in height so that the scaffold plate frame 2 contacts the slate roof and the scaffold plate 3 also contacts the slate roof when a person gets on the scaffold plate 3. It is desirable that the pipe 21 is formed. It is conceivable that the surface of the angle 22 that functions as a support portion and the underbar 23 are welded to the square pipe 21 at a height that is approximately 15 to 16 mm above the lower end of the square pipe 21. The angle 22 and the underbar 23 may be formed at positions other than those illustrated.

  Handrail mounting holes 24 are attached to predetermined positions on the outer side surfaces of the pair of square pipes 21. For example, in the case shown in FIG. 4, four handrail attachment holes 24 are attached in total. The handrail mounting hole 24 has a cylindrical shape in which a hole for inserting the handrail 6 is formed in the upper portion, and the handrail 6 is inserted into the handrail mounting hole 24 by inserting the handrail 6 into the handrail mounting hole 24. The slide 6 is formed so as to be installed on the slate roof scaffold member 1. The handrail 6 is inserted into the handrail mounting hole 24. The handrail attaching hole 24 may be attached at a position in contact with the slate roof when the slate roof scaffold member 1 is installed on the slate roof, or may be attached so as not to contact the slate roof. Absent.

  Further, a connecting piece 222 for connecting the scaffolding plate frame 2 to another scaffolding plate frame 2 is provided at the end in the longitudinal direction of the pair of square pipes 21, for example, another neighboring scaffolding plate frame 2. It is formed so as to be alternated with the connecting piece 222 formed in the above. An insertion hole for inserting a connection piece 222 formed in another square pipe 21 is formed at a location adjacent to the connection piece 222 in the square pipe 21, and is formed in each of the adjacent square pipes 21. By inserting the other connecting piece 222 into the insertion hole, the adjacent scaffold plate frames 2 are connected.

  The scaffold plate 3 is made of a metal such as aluminum or steel, for example, and has a substantially rectangular shape in plan view. The length in the longitudinal direction of the scaffold plate 3 is approximately the same as the length in the longitudinal direction of the scaffold plate frame 2, and the length in the short direction is, for example, 1 / th of the length in the short direction of the scaffold plate frame 2. The size of the scaffold plate 3 is not limited to the above-described example as long as it corresponds to the size of the scaffold plate frame 2. As described above, the scaffold plate 3 is on the surface of the angle 22 that functions as a support portion or the underbar 23 in the scaffold plate frame 2 and between the side surface of the square pipe 21 that functions as a frame portion and the auxiliary piece 221. Respectively. Specifically, as described above, the present embodiment has three scaffolding plates 3, and one of the three scaffolding plates 3 is arranged between one square pipe 21 and the auxiliary piece 221. Another one is arranged between the auxiliary piece 221 and the auxiliary piece 221, and the last one is arranged between the other square pipe 21 and the auxiliary piece 221.

  The scaffold plate 3 may be subjected to various treatments such as forming a plurality of through-holes, providing an uneven shape for preventing slipping, and performing circumferential flange processing. Various types of scaffold plates 3 can be used for the slate roof scaffold member 1 in the present embodiment.

  The laying plate frame 4 (laying plate frame portion) is made of a metal such as aluminum or steel, and has a substantially rectangular shape in plan view. For example, the length of the floorboard frame 4 in the longitudinal direction of the floorboard frame 4 is equal to or shorter than the length of the shorter side of the scaffolding board frame 2. The length in the short direction is, for example, 0.25 m (may be other than the case illustrated). As shown in FIG. 5 and FIG. 6, a surrounding portion 42 on which the floor plate 5 is placed is formed on the upper side of the floor plate frame 4. Further, a locking piece 41 (locking member) formed of a pair of L-shaped steels is welded to the lower side of the floor plate frame 4 in a direction facing each other. For example, one surface of the L-shaped steel is welded to the laying plate frame 4, and the other surface (a surface extending downward from one end of the welded surface) functions as the locking piece 41.

  The pair of locking pieces 41 is adjusted such that the length between the one locking piece 41 and the other locking piece 41 is a length corresponding to the length of the scaffolding plate frame 2 in the short direction. Yes. Specifically, the length between the one locking piece 41 and the other locking piece 41 is adjusted to be slightly longer than the length of the scaffolding plate frame 2 in the short direction. By such adjustment, when the floorboard frame 4 is installed on the scaffolding board frame 2, the pair of locking pieces 41 are arranged so as to sandwich the outside of the scaffolding board frame 2. Here, as shown in FIG. 1, it is conceivable that the slate roof scaffold member 1 is installed on an inclined slate roof. A pair of locking pieces 41 is formed as described above, and when the laying plate frame 4 is installed on the scaffolding plate frame 2, the scaffolding plate frame 2 is locked (pinched) by the locking pieces 41 of the laying plate frame 4. Therefore, even when the slate roof scaffolding member 1 is installed on the slanted slate roof, it is possible to prevent the floorboard frame 4 from slipping down.

  The surrounding portion 42 is formed by a wall portion that surrounds the four sides of the upper surface of the floorboard frame 4. As described above, the floor plate 5 is placed inside the enclosure portion 42.

  The floor board 5 is made of, for example, wood and has a substantially rectangular shape in plan view. For example, the floor plate 5 has a size corresponding to the size of the surrounding portion 42. As described above, the scaffold 11 can be assembled on the floor board 5. When the scaffold 11 is assembled on the floor board 5, the jack base of the scaffold 11 is nailed to the floor board 5, for example.

  The handrail 6 is made of metal such as aluminum or steel. As described above, the handrail 6 can be attached to the slate roof scaffold member 1 by being inserted into the handrail attachment hole 24. Due to such a configuration, the handrail 6 can be attached to and detached from the slate roof scaffold member 1 by an easy method. In FIGS. 1 and 2, the handrail 6 is attached to both sides of the slate roof scaffold member 1. In the present embodiment, the shape of the handrail 6 is not particularly limited.

  The slate roof scaffold member 1 has the above-described configuration, for example. Next, an example of a method (scaffold member installation method) for installing the slate roof scaffold member 1 on the slate roof will be described.

  The slate roof scaffold member 1 as described above is installed on the slate roof as shown in FIG. 7, for example. That is, the slate roof scaffold member 1 such that the lower surface of the slate roof scaffold member 1 (the outer side surface of the lower square pipe 21) is in contact with the fixture 7 such as a bolt or a nut for fixing the slate roof. 1 is installed on the slate roof. By installing the slate roof scaffold member 1 in this manner, the slate roof scaffold member 1 is locked to the fixture 7. As a result, even if the slate roof scaffold member 1 is installed on an inclined slate roof, the slate roof scaffold member 1 can be prevented from slipping down. The slate roof scaffold member 1 is desirably installed on the slate roof so that the angle 22 and the underbar 23 do not contact the fixture 7. In other words, the slate roof scaffold member 1 is desirably installed on the slate roof so that the angle 22 and the underbar 23 are not positioned on the fixture 7.

  Thus, the slate roof scaffold member 1 in this embodiment has the scaffold board frame 2 and the scaffold board 3. With such a configuration, the scaffold member 1 can be easily installed on the slate roof by installing the scaffold plate 3 after installing the scaffold plate frame 2 on the slate roof. As a result, the slate roof scaffold member 1 can be safely installed on the slate roof by an easy method.

  Further, the slate roof scaffolding member 1 in the present embodiment includes a floor plate frame 4 and a floor plate 5. With such a configuration, after the scaffolding frame 2 and the scaffolding plate 3 are installed on the slate roof, the scaffolding frame 11 is installed and the scaffolding 11 is assembled on the slate roof by placing the wooden floorboard 5. It becomes possible. As a result, it is possible to safely maintain, inspect, and repair the slate roof and adjacent walls with an easy method.

  Moreover, according to this embodiment, the flooring board 5 is formed in the form which crosses the transversal direction of the scaffold member 1 for slate roof, and has sufficient size as a flooring board which fixes a jack base. Therefore, scaffolds 11 having various sizes (having various widths) can be assembled on the slate roof scaffold member 1. For example, if the eaves of the roof on the upper floor where the slate roof scaffold member 1 is installed are deep, the scaffold 11 may come into contact with the roof on the upper floor in the case of a small scaffold 11. In this case, for example, it is conceivable to assemble a scaffold 11 having a large width. Thus, the flexible scaffold 11 can be formed by taking a sufficient size of the floorboard 5.

  Further, according to the present embodiment, the floorboard frame 4 can be installed at any location of the scaffolding board frame 2. Therefore, according to the magnitude | size of the scaffold 11 installed on the scaffold member 1 for slate roofs, the space | interval of the baseplate frame 4 installed on the scaffold board frame 2 can be adjusted.

  In addition, the structure of the scaffold member 1 for slate roof demonstrated by this embodiment is an example to the last. The slate roof scaffold member 1 can have various other configurations.

  For example, it is conceivable to form a protective layer made of silicon or the like on the surface of the scaffolding plate frame 2 that contacts the slate roof, such as the lower surface of the square pipe 21 or the lower surface of the angle 22 or the underbar 23. By forming a protective layer made of silicon or the like on the surface in contact with the slate roof, the function as an anti-slip or cushion (function to absorb impact), the function to suppress cracks in the slate roof, between the square pipes 21 It can be expected to exhibit a function of adjusting the height deviation.

  Moreover, in this embodiment, the case where the auxiliary piece 221 was formed in each of a pair of angles 22 was demonstrated. However, the location where the auxiliary piece 221 is formed is not limited to the case described in the present embodiment. For example, the auxiliary piece 221 may be formed on only one of the pair of angles 22. Further, the auxiliary piece 221 may be formed on the underbar 23 instead of being formed on the angle 22 or together with the angle 22.

  For example, as shown in FIG. 8, it is also conceivable to form a markan 211 for passing a rope used when lifting the scaffold member 1 for a slate roof with a crane vehicle in the scaffold plate frame 2. By forming the marcan 211 on the scaffolding plate frame 2, it is possible to easily lift the slate roof scaffold member 1 with a crane vehicle by passing the rope through the marcan 211. For example, the slate roof scaffold member assembled on the ground 1 can be easily installed on the slate roof. The Malcan 211 may be configured to be attachable to and detachable from the scaffolding plate frame 2 by, for example, screwing.

  Further, for example, when the slope of the slate roof on which the slate roof scaffold member 1 is installed is large, the length of lifting the jack base located on the lower side may become too long (the stroke of the jack may be insufficient). In order to deal with such a fear and to alleviate the inclination of the slate roof, it is also conceivable to use a floor board frame 8 with an adjustable inclination angle as shown in FIG. 9 instead of the floor board frame 4.

  The base plate frame 8 has a base portion 81 on which the locking piece 41 is formed and an enclosure portion 82 on which the base plate 5 is placed. The base portion 81 and the enclosure portion 82 can be rotated by a shaft portion 83. It is pivotally supported. Specifically, the base portion 81 and the surrounding portion 82 have a substantially rectangular shape in plan view, and are rotatably supported by the shaft portion 83 at one of the short side end portions of the four sides. With such a configuration, the enclosure portion 82 can be inclined as shown in FIG. 9 by rotating the enclosure portion 82 with the shaft portion 83 as a fulcrum in a state where the floor plate 5 is installed inside the enclosure portion 82. I can do it. Accordingly, it is possible to incline the bottom plate frame 8 (the bottom plate 5) in a state where the bottom plate frame 8 is installed on the scaffolding plate frame 2. As a result, the inclination of the slate roof can be reduced. A locking piece 41 is formed on the base 81. Therefore, the base plate frame 8 can be installed on the scaffold plate frame 2 in the same manner as the base plate frame 4.

  It is also conceivable to form a support portion 84 (enclosure locking member) that locks the enclosure portion 82 in a state where the enclosure portion 82 is engaged with the base portion 81 at a predetermined angle. The support portion 84 is pivotally supported with respect to the base portion 81 so as to be rotatable about the shaft portion 85. With this configuration, for example, when the enclosure portion 82 is inclined, the support portion 84 can be rotated with the shaft portion 85 as a fulcrum, and the support portion 84 can be brought into contact with the lower portion of the enclosure portion 82. . As a result, the inclined state of the enclosure portion 82 can be supported from below by the support portion 84, and the enclosure portion 82 can be more firmly inclined.

  In the present embodiment, the base plate frame 4 and the base plate frame 8 are formed so as to cross the scaffold plate frame 2. However, as long as it is possible to install the base plate 5 according to the jack base of the scaffold 11, the base plate frame 4 and the base plate frame 8 do not necessarily have to be formed so as to cross the scaffold plate frame 2. For example, two floorboard frames 4 may be formed in the lateral direction of the scaffolding board frame 2. In this case, the locking piece 41 is formed so as to sandwich the scaffold plate frame 2 and the scaffold plate 3, for example.
