Description

  The present invention relates to a temporary slope device, and more particularly, to a temporary slope device disposed on a temporary scaffold for construction work and civil engineering work.

  In a frame scaffold and a single-pipe scaffold temporarily installed at a construction / civil engineering construction site, a step is generated on the floor due to a difference in height of the work passage, a level difference between the lifting equipment and the work passage, or the like. In order to eliminate such a level difference, a temporary slope is disposed at a proper position. This kind of slope is assembled by a single pipe, fasteners (clamp, wire, etc.), scaffolding board, pier, etc. The temporary slope forms a ramp that obliquely connects the floor surfaces that are displaced in the vertical direction, and allows a carriage such as a unicycle, a wheelbarrow, and a material cart to pass or a worker to walk.

Further, slide type, drawer type, or folding type slope devices that can be stored compactly when not in use are disclosed in JP-A-9-41605, JP-A-9-41606, and JP-A-2000-220111. Yes. According to the slope devices described in these publications, slide-type, drawer-type, or fold-type movable members are extended when used, extended or expanded to develop the slope-forming members, and theater stages, stages, etc. A ramp can be formed at the step portion.

  Conventional temporary slopes installed on building scaffolds, single-pipe scaffolds, etc. for construction and civil engineering work shall have a structure in which single-pipe pipes, scaffolding boards, piers, etc. are assembled by fastening tools (clamps, wire numbers, etc.) Therefore, not only complicated assembly work is required when the slope is installed or moved, but also a relatively large amount of waste materials such as piers and fasteners are generated when the slope is removed and dismantled.

  On the other hand, the slide-type, drawer-type, or fold-type slope device disclosed in the above-mentioned Patent Documents 1 to 3 sets the slope by extending the movable member at the time of use, expanding or expanding it, and developing the ramp member. Etc. can be formed. Therefore, if it is possible to divert such a slope device to a temporary scaffold or the like at a construction site, it is considered that the work of slope installation and slope transfer can be greatly simplified.

  However, the slope devices disclosed in the above-mentioned Patent Documents 1 to 3 include a mechanical interlocking mechanism that is set in advance to enable the development of the divided ramp members, support members, leg members, and the like. The inclination angle, level difference, and dimensions of each part can only be set to values within a limited range. In addition, since the load resistance of the mechanical interlocking mechanism and the like is relatively low, the load resistance of the ramp is limited to a relatively low value.

  On the other hand, temporary slopes installed on framework scaffolds, single-pipe scaffolds, etc. for construction and civil engineering work require a relatively high load capacity and must be adapted to any inclination angle and level difference. Therefore, from the viewpoint of load resistance, dimensional adaptability, and the like, the slide type, the drawer type, or the folding type slope device as disclosed in Patent Documents 1 to 3 described above is a construction site used under relatively severe conditions. As a slope, there are circumstances that are difficult to use.

  The present invention has been made in view of such circumstances. The purpose of the present invention is to simplify the installation work and relocation work of the slope and reduce the amount of waste generated at the time of removal and dismantling. To provide a temporary slope device having a high load resistance that can be installed on a framework scaffold for construction, a single pipe scaffold, etc., and an arbitrary inclination angle and level difference that can be applied to a framework scaffold, a single pipe scaffold, etc. .

In order to achieve the above object, the present invention provides a temporary slope device that is disposed on a floor portion having a height difference and forms a ramp between the floor surface on the high floor side and the floor surface on the low floor side.
Left and right girders, end frames and horizontal members laid between the girders so as to bridge the left and right girders, scaffold plates laid on the horizontal members, and end frames on the low floor side And a step part attached to the outside,
The step portion has a roller protruding below the end frame on the low floor side, and the roller is supported on the floor surface on the low floor side so as to be rollable. To do.

  According to the above-described configuration of the present invention, the temporary slope device has a configuration in which a scaffolding plate is laid on a frame body formed by a girder, an end frame, and a horizontal member, and is provided at a low floor side end portion of the frame body. The provided step portion protrudes below the end frame on the low floor side and contacts the floor surface on the low floor side in a rollable manner. Since the roller rotates with respect to the floor surface on the low floor side, the frame body can be installed at an arbitrary inclination angle.

  In order to install the temporary slope device of the present invention on a temporary scaffold or the like having a height difference, the high-floor side end frame of the temporary slope device is locked to the floor on the high floor side, and the step portion is grounded to the floor surface on the low floor side You can do it. Therefore, according to the temporary slope device of the present invention, the installation work, the transfer work, etc. of the slope are greatly simplified compared to the conventional slope structure in which the single pipe, the scaffolding plate, the pier, etc. are assembled by the fasteners. To do. Further, when removing and dismantling the temporary slope device, almost no waste material is generated, which is extremely advantageous in practice. Furthermore, the temporary slope device has a structure in which the scaffolding plate is supported by a frame made of girders, end frames, and horizontal members, so that it can be installed on a frame scaffold for construction and civil engineering, a single pipe scaffold, etc. High load resistance can be obtained relatively easily. Further, as described above, since the roller rotates with respect to the floor surface on the low floor side, it is possible to arbitrarily set the slope inclination angle and the level difference that can be applied to the frame scaffold, the single pipe scaffold, and the like. The roller is also an effective means for preventing floor rubbing or floor damage that may occur during the movement of the temporary slope device.

  According to the temporary slope device of the present invention, it is possible to simplify the slope installation work and transfer work, and to prevent or suppress the generation of waste material during removal and dismantling. In addition, according to the temporary slope device of the present invention, an inclination angle that can be applied to a frame scaffold, a single pipe scaffold, etc. while ensuring a high load resistance that can be installed on a frame scaffold for a construction / civil engineering work, a single pipe scaffold, etc. And the arbitraryness of the level difference can be achieved.

  According to a preferred embodiment of the present invention, the temporary slope device includes a locking tool that can be locked to a structural member on the floor surface on the high floor side at the end portion on the high floor side. Preferably, the step portion includes an inclined plate extending obliquely downward from the upper surface of the end frame on the low floor side and toward the floor on the low floor side, and an edge member having a circular cross section integrated with the tip edge of the inclined plate. The inclined plate is connected to the outer peripheral surface of the edge member in the tangential direction. According to such a step unit, a transport carriage such as a unicycle can smoothly enter the ramp of the temporary slope device from the floor surface on the low floor side.

  According to a further preferred embodiment of the present invention, a plurality of horizontal members are arranged at predetermined intervals in the girder direction, and the horizontal member located in the center part of the girder direction is arranged in the horizontal direction end region. It is arranged at a relatively higher position than the frame. Preferably, a support for supporting the end of the horizontal member is arranged on the inner surface of the beam member. The support has a relative height difference, and the relative height difference of the horizontal member is attached by the height difference of the support. The total length of the temporary slope device usually has a support structure in the form of a simple beam set to a dimension between fulcrums of about 3 to 5 m (for example, 4 m). Therefore, it is desirable to slightly raise the scaffolding plate in the central part upward due to the height difference of the horizontal member. In the central part of the road surface of the sloping road, a whirling due to the upward bulge occurs, but this is canceled out by the downward displacement of the central part of the girders during use. Therefore, it is possible to prevent the occurrence of unevenness that may occur on the ramp during use due to the difference in height of the horizontal members.

  According to another preferred embodiment of the present invention, a temporary slope device includes a columnar handrail support member that protrudes upward from a predetermined position of a girder, and a foot plate integrally formed at the lower end of the handrail support member. Have The leg plate has a cross section having a lower surface opened to receive the upper end portion of the handrail support member. A bracket that supports the handrail support member protrudes from the outer surface of the beam member, and the leg plate is disposed below the bracket so as to protrude below the beam member. When storing and storing a large number of frames stacked vertically, the tip of the handrail support member of the lower frame is received by the opening area on the lower surface of the foot plate, and positioning or load collapse prevention of the frames stacked vertically In addition, it is possible to secure a gap in which the forklift claw portion can be inserted between the stacked frames. The leg plate also improves the workability of the frame moving work by separating the lower surface of the frame placed on the horizontal floor from the floor. The separation between the frame body and the floor surface by the leg plate is also advantageous for preventing corrosion of the frame body.

  According to still another preferred embodiment of the present invention, the end frame has a cross section that opens to the inside of the frame so that the end of the scaffold plate can be received, and regulates the position of the adjacent scaffold plate in the width direction. A partition plate is disposed in the opening region of the end frame. The partition plate prevents the adjacent scaffold plates from separating and generating a large gap between the scaffold plates. Preferably, the girder is made of a metal tube having a square cross section that can be divided at the center, and a reinforcing material straddling the end of each metal tube is provided in the divided portion of the metal tube. Such division of the girders can improve workability such as storage and conveyance of the frame.

  FIG. 6 is a side view illustrating the use state of the temporary slope device 1.

  FIG. 6 schematically shows floors LF and HF such as a frame scaffold or a single pipe scaffold. The temporary slope device 1 is disposed across the floors LF and HF so as to form a walking ramp between the floor LF having a relatively low floor level and the floor HF having a relatively high floor level. . The hook-shaped portion of the hook portion 6 is locked to the scaffold steel pipe 11 of the floor HF. The roller 74 of the step unit 7 contacts the upper surface of the floor LF so as to be able to roll and is supported by the floor LF. The load of the temporary slope device 1 is transmitted to the floors HF and LF via the hook portion 6 and the roller 74, and is supported by the supporting force of the floors HF and LF. Note that one or both of the floors LF and HF may be, for example, a frame of a building structure being constructed or a floor such as a veranda, the ground, an artificial ground, a vehicle bed, and the like.

  Since the girder 2 has a structure of a simple beam supported by the hook portion 6 and the roller 74, a slight bending in the direction indicated by the arrow G occurs in the central portion of the girder 2, and the girder 2 is In general, it is slightly curved downward. The central support 21 located at the relatively high position L3 (FIG. 2B) is relatively greatly displaced downward, and the intermediate support 21 (height L2) is slightly displaced downward. . As a result, the floor bulge formed in the center of the floor surface of the scaffold board 8 (FIG. 2A) is eliminated, and a planar ramp without the bulge is formed by the scaffold board 8.

  FIG. 7 is a cross-sectional view showing the relationship between the height difference between the floors HF and LF and the inclination of the temporary slope device 1.

  When the height difference between the floors HF and LF is sequentially increased to ΔL1, ΔL2, and ΔL3, the inclination angle of the temporary slope device 1 is increased to θ1, θ2, and θ3. Since the hook part 6 rotates around the scaffolding steel pipe 11, it adapts to changes in inclination angles (angles θ1, θ2, θ3). On the other hand, the roller 74 of the step unit 7 rolls on the upper surface of the floor LF and follows changes in the inclination angle (angles θ1, θ2, and θ3). The inclined plate 71 and the pipe body 72 of the step portion 7 prevent a step from being formed between the scaffold plate 8 and the floor LF. The outer peripheral surface of the tube body 72 is exposed at the tip of the step portion 7, and the upper surface of the inclined plate 71 is connected to the outer peripheral surface of the tube body 72 so as to extend in the tangential direction of the tube body 72. The transport carriage can smoothly transition from the floor LF to the ramp on the scaffolding plate 8 without receiving an impact during the movement of the step.

  Further, the temporary slope device 1 can be moved in an inclined posture shown in FIG. The operator removes the handrail 9 from the vertical pipe 25 of the girder 2 and lifts the end of the hook portion 6 to a height as shown by the floor HF to incline the temporary slope device 1 as a whole. The temporary slope device 1 may be moved in the direction of the arrow M while rolling the roller 74 that is grounded. By using the roller 74, floor rubbing or floor surface damage associated with the movement of the temporary slope device 1 can be effectively prevented.

  FIG. 8 is an elevation view showing a storage form of the temporary slope device 1.

  Since the temporary slope device 1 can be stacked as shown in FIG. 8 with the handrail 9 removed from the vertical pipe 25 of the girder 2, it can be stored or stored in a compact manner. The lower surface opening area of the leg plate 26 receives the tip of the vertical pipe 25 and is used as positioning means or load collapse prevention means of the temporary slope device 1 stacked vertically, and between the stacked temporary slope devices 1. Spacer means for ensuring a gap E into which the forklift claw portion can be inserted is configured. The temporary slope device 1 may be configured so that it can be stacked after the girder 2 is separated at the central portion or the like, if desired.
