Description

[Technical field]

[0001] To provide a movable scaffolding installation structure which can be installed easily and inexpensively even when the distance between adjacent buildings is narrow, and which enables workers to repair, repair, and maintain the exterior walls, eaves gutters, and accessories of buildings without encountering problems such as falls during use. [Background technology]

[0002] In recent years, existing buildings are constantly exposed to various abnormal weather conditions, and as a result of damage and deterioration of the roof surroundings, including the eaves gutters, there is a need to install new high-performance eaves gutters. When repairing, renovating, or maintaining the roof surroundings, such as the above example, of existing buildings such as houses, it is common to install scaffolding around the building and at the borders with neighboring houses prior to the various types of work. That is, the actual renovation of a building first requires the installation of scaffolding around the building, which requires time, cost, and other issues that cannot be ignored or are difficult to adjust.

[0003] Since the scaffolding is installed by a contractor different from the contractor performing the repairs, etc., the schedule for the repairs, etc. had to be determined after waiting for the schedule for the scaffolding installation. In addition, the scaffolding was set up by bringing parts (materials) according to the height and width of the building (renovation area) to the site, assembling these materials, and setting up the scaffolding to cover the construction area, so even though the materials themselves were reusable, the cost of setting up the scaffolding was not cheap. In other words, it was necessary to secure a place to temporarily store the huge amount of materials and a place to set up the scaffolding, but it was often difficult to secure such a place. Furthermore, especially when the boundary between adjacent houses was narrow, it was also necessary to take measures not to damage the garden equipment and trees of the neighboring houses. Summary of the Invention [Problem to be solved by the invention]

[0004] As mentioned above, the conventional method of setting up scaffolding involves bringing parts and components appropriate to the height and width and length of the area to be renovated to the site, assembling them and setting up the scaffolding to cover the construction area, which entails problems such as time and cost that are difficult to adjust.

[0005] Therefore, the present invention aims to propose an installation structure for a movable scaffold that can be installed easily and inexpensively even when the distance between adjacent buildings is narrow, and that can be used to repair, repair, and maintain the exterior walls, eaves gutters, and accessories of a building without causing problems such as workers falling. [Means for solving the problem]

[0006] The present invention has been proposed in view of the above, and is a movable scaffolding installation structure that can change its position along the outer wall surface of a building, The base end Two or more attached to the building It is a linear safety belt. A mounting body, two or more supports each having an upright portion, a horizontal portion, and a connecting portion connecting the two, and a mounting body and a supporting member for connecting the two. As if straddling at right angles Installed in an erected position This ensures sliding movement. A track body, a support arm whose end is located inside the track body, a leg extending vertically from the support arm, and a pair of legs on the outside and inside of the leg, respectively. Working scaffolding The present invention relates to a movable scaffolding installation structure comprising a working base on which the movable scaffolding is integrally provided. The outside and inside of the legs are based on the legs arranged at a specified distance from the exterior wall surface of the building, with the building side being the inside and the opposite side being the outside.

[0007] Further, the present invention provides the above-mentioned installation structure, Working scaffolding Among these, at least one of the legs is located on the inner side. Working scaffolding The present invention also proposes an installation structure for a movable scaffold, which is characterized in that it is movable in the height direction relative to the legs.

[0008] Furthermore, the present invention also proposes an installation structure for a movable scaffold, characterized in that in the installation structure, the track body and the end portion of the support arm positioned on the track body are two or more. Effect of the Invention

[0009] The installation structure for the movable scaffolding of the present invention is inexpensive and easy to install even when the distance between adjacent buildings is narrow, and does not cause problems such as falling when used. Workers riding on the working base that slides along the exterior wall surface of the building can change their working position as the construction work progresses. Therefore, it can be applied to the exterior wall surfaces, eaves gutters, and accessories of buildings very easily and inexpensively without causing various problems related to construction and costs. Working scaffolding For various construction such as eaves gutters on buildings, the Working scaffolding can be used.

[0010] The above Working scaffolding Among these, at least one of the legs is located on the inner side. Working scaffolding In the case where the leg portion is movable in the height direction relative to the leg portion, construction of an exterior wall surface having a large height dimension can be more easily accomplished.

[0011] When there are two or more ends of the support arm positioned on the track body, the operation of the support arm moving via the track body, i.e., the movement of the work platform, can be more stably performed. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] The installation structure of the movable scaffolding of the present invention is a structure for installing a movable scaffolding that can change its position along the outer wall surface of a building, The base end Two or more attached to the building It is a linear safety belt. A mounting body, two or more supports each having an upright portion, a horizontal portion, and a connecting portion connecting the two, and a mounting body and a supporting member for connecting the two. As if straddling at right angles Installed in an erected position This ensures sliding movement. A track body, a support arm having an end located within the track body, a leg portion extending vertically from the support arm, and a pair of legs on the outer and inner sides of the leg, respectively. Working scaffolding and a working base on which the workpiece is integrally provided.

[0014] The mounting body, the support body, the track body, and the working platform that constitute the installation structure of the movable scaffolding of the present invention will be described below in that order.

[0015] The mounting body may be a frame-shaped material that is hung (hooked) onto the upper end of a flat roof or the like, or it may be a number of approximately linear materials (safety belts) whose base ends are attached to the building, or a combination of these, and does not specify the part of the building to which it is attached. For example, in the case of the frame-shaped member, there is no limitation on its shape, etc., so long as it is a frame-shaped member that can be hung (hooked) on a rooftop or other facility. In the case of the safety belt, the location where the base end of the approximately linear material is attached may be the eaves on the opposite side of the work target, the ridge top, or a combination of both, but is not limited to these, and a known safety rope (rope, belt) may be attached as long as it has the strength to ensure safety. In the case of a hipped roof, it may be attached to the other three sides. The attachment means (method) may be any type, such as engagement, and the material may be any material, such as a steel strip or linear material, or a rope, belt, or other material made of synthetic fibers such as nylon, as long as it has the strength to support other members including the support body.

[0016] The support body is a triangular material having at least an upright portion, a horizontal portion, and a connecting portion connecting the two, which are fixed to the mounting body as described above, and each portion (each side) can be made of a square material (square pipe) having excellent tensile strength, or an angle material such as an L-shaped, U-shaped, or flat angle material. Although the standing portion is fixed to the mounting body, the fixing point is not limited to the upper end, but may be fixed at any appropriate position, and the erection angle is not limited to approximately vertical. Furthermore, the horizontal side portion may be aligned along a roof surface having a roof slope, or along a substantially horizontal upper surface such as a flat roof. Furthermore, the connecting parts may be arranged inclined or horizontal, or a plurality of connecting parts (members) may be provided, in order to obtain the required strength as a roof slope or support.

[0017] Each side forming the support is connected in an angle-adjustable manner, so that it can be stably applied to the rooftops of various buildings and to the roof slopes of houses, etc. Any known configuration may be adopted for this purpose, and for example, multiple mounting holes may be provided in the upright portion, and the connecting portion may be fixed to any of the mounting holes while adjusting the angle appropriately.

[0018] In addition, in this movable scaffolding, two or more of these mounting bodies and supports are provided depending on the size of the building, etc., but since each is of simple construction, the cost and weight (load) do not increase.

[0019] As described above, the track body is a member that is installed in a bridged manner relative to the support body, and is installed so as to span two or more supports perpendicularly. That is, it is installed so as to be arranged perpendicularly and horizontally relative to the support body, and so as to ensure sliding movement. This sliding movement is performed in a state in which the work base is suspended and supported, so in principle at least one track body is provided as a moving means on the upright part of the support body, but an additional (sub) track body may be provided as a regulating means to ensure smooth movement. That is, the track body as a moving means is essential, and the sliding movement cannot be performed with only the track body as a regulating means. For example, when forming a continuous rail material having a U-shaped or square U-shaped cross section, the rail material may be attached to the support. This attachment structure may be one in which the rail material is directly fixed with a fastener or the like, or one in which a holder is fixed to the support and the rail material is held by the holder. It is preferable that there are two or more rail materials, in which case the multiple rail materials become the track body. At least one rail material is fixed to the standing part of the support, but when two or more rail materials are attached, the number of rail materials is not limited to the standing part alone, and they may be fixed to the standing part and the connecting part.

[0020] The track may be provided with a stopper (function) that limits (stops) the movement of the work platform. The stopper is assumed to limit the range of movement of the work platform and to prevent it from falling off the track. The configuration of the stopper is not particularly limited, but it may be, for example, a hole or slit provided at any position on the end or middle of the track into which a rod or plate is inserted.

[0021] The work platform includes a support arm having a tip located within the track body, a leg extending vertically from the support arm, and a support body integrally provided on the outer and inner sides of the leg. Working scaffolding Each of these parts is mainly made of round or square pipes and shaped materials, and the materials can be of any material as long as they are lightweight and strong. Working scaffolding Each of the above may be a single member, or each may be made of a plurality of members. If the member is made of a plurality of members, the assembly may be performed by any known method such as fastening or welding.

[0022] From the viewpoint of stability, it is desirable to provide two or more ends of the support arms, similar to the track body, and the ends positioned inside the track body are provided with rollers or the like, but the number and specific configuration are not limited. Note that these rollers or the like are a moving means for moving inside the track body, but may also serve as a regulating means for preventing the work base from falling over, etc.

[0023] The legs are parts that extend vertically from the support arms, and using a ladder body that extends in the height direction as in the illustrated embodiment is desirable from various standpoints, such as stability. That is, by arranging the ladder body parallel to the exterior wall surface of a building, bottom plates or treads on which workers performing various construction work stand can be easily attached to the outside and inside of the ladder body, making construction work stable. However, since the ladder body itself often gets in the way of work when carrying out various construction work on the exterior wall surface of a building, it is preferable to use a ladder body with a base plate or step formed on the inside of the ladder body. Working scaffolding The worker simply rides on the vehicle and performs the work.

[0024] The above Working scaffolding is a member that is provided integrally with the outer and inner sides of the leg and has a bottom plate or step on which workers stand to carry out various construction work, and it is desirable to provide a safety frame or the like to prevent falls and other accidents while carrying out work. Working scaffolding The inner side is formed so as to extend outward from the leg. Working scaffolding The first leg may be formed (or attached) so as to extend inward in a similar manner, but may also be formed (or attached) so as to extend further inward from the second leg, with the second leg combined with the inside of the first leg in a superimposed (contacting) manner. As explained above, a ladder body may be used as the leg, but a ladder body may also be used as the second leg. Two ladders that can slide in the length direction are already available on the market as extendable ladder materials, and this ladder material may be used as the leg and second leg that can slide in a stacked manner. In this case, the ladder located at the top becomes the leg, and the ladder located at the bottom becomes the second leg. As in this example, the second leg located on the inside, i.e., the inside Working scaffolding However, if the legs are movable in the height direction, construction of exterior wall surfaces having large height dimensions can be accomplished more easily.

[0025] The support arm is a part that secures the distance from the tip disposed inside the track body, and may extend linearly or curvedly from the leg. For example, in the case of various construction work on the exterior wall surface, such as attaching components such as eaves gutters to the eaves, it becomes difficult to work if the work is too close to the exterior wall surface or the eaves, so the support arm can secure the working space. As mentioned above, it is desirable for the support arms of the work platform to be two or more, and it is desirable for at least one of them to have a moving means interlocked with the track body. In this case, the support is stable even when the work platform is stopped, and is also stable and smoothly moved when the work platform is moving like a sliding object.

[0026] It is desirable that each component of the installation structure for the movable scaffolding consisting of the mounting body, support body, track body, and working base be constructed from lightweight materials, and a worker positioned within the working base can work while being suspended and supported by the mounting body and support body, and can move in a sliding manner along the outer wall surface.

[0027] Therefore, when repairing, maintaining, etc. the exterior wall surface, eaves gutters, or accessories of a building, workers can change their work position by sliding along the exterior wall surface without problems such as falling. Therefore, contractors who carry out repairs and renovations can easily use the installation structure of this movable scaffolding before carrying out various construction work, and overall it is extremely easy to adjust time and costs. EXAMPLES

[0028] The installation structure of the movable scaffolding according to the first embodiment of the present invention shown in FIG. 1 includes two or more mounting bodies 1 whose base ends 11 are attached to a building A, two or more supports 2 each having an upright portion 21, a horizontal portion 22, and a connecting portion 23 connecting the two portions 21, 22, which are fixed to the mounting bodies 1, a track body 3 installed in a bridged state on the supports 2, a support arm 41 whose end portion (upper end 411, lower end 412) is located within the track body 3, a leg portion 42 extending vertically from the support arm 41, and a pair of support members 41 each attached to the outside and inside of the leg portion 42. Working scaffolding The work base 4 is integrally provided with the work bases 43A and 43B, and its position can be changed along the outer wall surface B.

[0029] The mounting body 1 is a safety belt having a plurality of extension wires 12, 13 extending from a hook-shaped (approximately U-shaped) base end 11 and connected to the upper end of the standing part 21 and the tip of the horizontal part 22, respectively, but the extension wires 12, 13 may be rope-shaped. In the drawing, 211 and 221 indicate mounting fixtures fixed near the tips of the standing part 21 and the horizontal part 22, and the extension wires 12, 13 are tied to these mounting fixtures 211, 221.

[0030] The materials forming the upright portion 21, the horizontal portion 22 and the connecting portion 23 of the support body 2 are each a U-shaped angle iron, and in this Example 1, the upright portion 21 is attached approximately vertically and the horizontal portion 22 is attached along the roof surface C. Further, a plurality of mounting holes 210 are formed in the standing portion 21, and the tip of the connecting portion 23 is connected to the mounting holes 210 such that the standing portion 21 is disposed substantially vertically.

[0031] In this embodiment 1, a plurality of these mounting bodies 1 and supports 2 are provided according to the size of the building A, but since each has a simple structure, the cost and weight (load) are not increased.

[0032] The track body 3 is made of rail members 3A and 3B that are installed in a spanning manner with respect to the support bodies 2, and is installed so as to span perpendicularly across (the upright portions 21 of) a plurality of support bodies 2. These rail members 3A and 3B are each arranged horizontally in the depth direction from the front side in FIG. In this embodiment 1, rail materials 3A and 3B are attached to two locations, one above and one below, on the outside of the upright portion 21 of the support body 2, and the rail material 3A is formed in a groove shape (square groove shape) that is open at the bottom, and the rail material 3B is formed in a groove shape (arc shape) that is open at the top, and the upper end 411 and lower end 412 of the support arm 41 are attached in a fitting manner between these, as shown in Figure 2(a).

[0033] The working base 4 includes the support arms 41, the legs 42, Working scaffolding Reference numerals 43 denote formed bodies of hollow square pipe material, and in this embodiment 1, the support arms 41 and the legs 42 can slide along the track body 3. In this embodiment 1, the leg 42 of the working base 4 is a ladder-shaped molded body having a plurality of steps 421, and a second leg 42B, which is a ladder-shaped molded body having a plurality of steps 426 on the inside, is combined in a superposed (contacting) manner and extends outward from the leg 42. Working scaffolding 43A is provided and extends inwardly from the second leg 42B. Working scaffolding 43B is provided. In the drawing, 422 denotes the leg 42. Working scaffolding 423 is a connecting reinforcement member that connects the tip of the second leg 42B to the tip of the second leg 43A. Working scaffolding 425 is a step-like horizontal piece attached so as to extend inward from the leg 42, and may be used to hang tools or the like used in work. The second leg 42B has hooks 424 that are open downward at two points fixed thereto, and the hooks 424 are fitted into two steps 421 of the leg 42 from above, thereby attaching the leg 42 and the second leg 42B in an overlapping (contacting) state, as shown in FIG. 2(b). It should be noted that this hook 424 may be provided on the leg 42 instead of the second leg 42B. In that case, the hook 424 is attached to the leg 42 in the reverse direction so that the upper portion is open, and is attached so that the step 426 of the second leg 42B fits in from above.

[0034] As shown in Figure 2(a), the support arm 41 consists of a vertical piece 41A, a horizontal piece 42B, a diagonal piece 41C connecting them, and a reinforcing material 41D that reinforces the combined structure, and the respective tips of the horizontal piece 42B, the diagonal piece 41C, and the reinforcing material 41D are fixed to a connecting fitting 41E that is integrally attached to the upper end of the leg portion 42. The upper end 411 and the lower end 412 of the supporting arm 41, that is, the upper end 411 and the lower end 412 of the vertical piece 41A, are respectively fitted with metal fittings holding spherical and wheel-shaped rotating bodies (rollers).

[0035] The leg 42 is a ladder-like structure extending vertically from the support arm 41, and as described above, the ladder-like second leg 42B is combined with the inner leg 42 in a superposed (contact) manner and extends outward. Working scaffolding 43A is formed at the lower end of the leg 42 and extends inward. Working scaffolding 43B is formed at the lower end of the second leg portion 42B. Working scaffolding As described above, 43A and 43B are combined in a triangular shape with the leg portion 42 or the second leg portion 42B by the connecting reinforcements 422 and 423, and are fixed at approximately right angles to each other.

[0036] In the movable scaffold consisting of the mounting body 1, support body 2, track body 3, and working base 4, each of the components 1 to 4 is constructed from lightweight materials, and a worker positioned within the working base 4 can work while being suspended and supported by the mounting body 1 and support body 2, and can slide along the outer wall surface to change his / her position. This makes it easy to repair, maintain, and renovate the exterior walls, eaves gutters, and accessories of the building. Working scaffolding Workers can climb onto the 43B and work on eaves gutters and other structures by extending outward. Working scaffolding Just get on the 43A and do the work. EXAMPLES

[0037] The installation structure of the movable scaffolding in Example 2 shown in Figure 3(a) is different from Example 1, which is aimed at an ordinary house, i.e., building A, in that building D is a concrete structure, and the upper end of an exterior wall surface E that is long in the vertical direction is connected to a parapet E', which is a rising wall, and a substantially flat roof G is formed with a fence F attached to the upper end of the parapet E'.

[0038] In this embodiment 2, a mounting body 1' is used that is almost the same as that in the embodiment 1 (part of the extension wire 12 is omitted in the drawing), but it differs in that the extension wire 13 is not used, and further, a hook-shaped (approximately L-shaped) second mounting body 1" described later is used in combination.

[0039] In addition, in this Example 2, the support body 2' formed from the standing portion 21', the horizontal portion 22', and the connecting portion 23' is an angle material combined in a T-shape, and in this Example 2, the standing portion 21' is attached approximately vertically, and the horizontal portion 22' is attached along the upper surface of the parapet E', and the connecting portion 23' is a connecting metal fitting that connects them. In addition, a substantially vertical vertical side portion 24 is formed at the tip of the horizontal side portion 22', which is arranged to penetrate near the bottom end of the fence F, and this support portion 2' alone can be attached to the parapet E' in a fitted state from above (in reality, since the fence F is present, it cannot be attached in a fitted state from above, but the result is that it is arranged in a fitted state), so it can also serve as the second mounting body 1".

[0040] Therefore, the mounting body 1' and the support body 2' (second mounting body 1") can be stably attached to the parapet E'.

[0041] In this second embodiment, the track body 3 (rail members 3A, 3B) is used which is exactly the same as that in the first embodiment, so the same reference numerals are given to the drawings and the description thereof is omitted.

[0042] In addition, in the second embodiment, the support arms 41 and legs 42, which are exactly the same as those in the first embodiment, and the Working scaffolding Since the same reference numerals are used in the drawings, the explanation will be omitted.

[0043] As such, the track body 3, support arm 41, and leg 42 in this Example 2 are exactly the same as those in Example 1, so construction can be carried out by stably sliding them along the outer wall surface E in the same manner as in Example 1.

[0044] The second leg 42B' in this second embodiment extends inward as shown in FIG. Working scaffolding This is similar to the first embodiment in that 43B is formed at the lower end of the second leg 42B', a hook 424 is provided, and a step 426 is provided, but it differs from the first embodiment in that the height dimension is shorter and no connecting reinforcement material 423 is used. Therefore, the second leg portion 42B' is obviously lighter than the second leg portion 42B in the first embodiment, and is therefore lighter in the vertical direction, i.e., in the height direction, than the leg portion 42. Working scaffolding The position of 43B can be easily changed, and as a result, the construction of the exterior wall surface E, which has a large height dimension, can be more easily accomplished.
