Description

  The present invention relates to a slide scaffold facility used during construction of a structure.

  Conventionally, the most common external scaffold for constructing the outer wall of a building is to assemble the framework scaffold sequentially from the ground, but this kind of scaffold is applicable to the construction of high-rise buildings. I can't. Therefore, there is a conventional slide scaffold that can slide upward. This slide scaffold is for climbing by sliding the temporary scaffold unit upward as the building rises.

As a conventional slide scaffold, as disclosed in Patent Document 1, there is one that raises a temporary scaffold unit using a chain hoist. In this slide scaffold, the temporary scaffold unit is suspended and supported by the chain hoist. However, if you try to support the work load when using it as a work scaffold with the chain hoist, you can use a large chain hoist or the quantity of chain hoist The cost must be increased. Therefore, a support structure for supporting the temporary scaffold unit may be separately installed. For example, there is a method in which a support bracket is fixed to an outer wall surface and a temporary scaffold unit is placed on the support bracket. With this slide scaffold, before climbing the temporary scaffold unit during climbing, remove the support bracket that supports the temporary scaffold unit, lift the temporary scaffold unit, attach the support bracket to the outer wall surface, and Place the temporary scaffold unit on.
JP 2001-73551 A

  However, in the conventional slide scaffold equipment described above, when the temporary scaffold unit is raised, if the support bracket is attached to the outer wall surface, the temporary scaffold unit is caught on the support bracket, and the temporary scaffold unit is raised to the repositioning position. Therefore, the temporary scaffold unit must be lifted after removing the support bracket, and there is a problem that the climbing work is complicated.

  The present invention has been made in consideration of the above-described conventional problems, and an object of the present invention is to provide a slide scaffold facility that can easily perform a climbing operation.

  The slide scaffold equipment according to the present invention is installed along the outer wall surface of the structure at the time of construction of the structure, and is temporarily fixed to the outer wall surface and slidable upward along the outer wall surface, In the slide scaffold equipment comprising a support structure for supporting the temporary scaffold unit, the temporary scaffold unit includes a slide rail extending in a vertical direction and a supported portion for supporting the temporary scaffold unit. The support structure is engaged with the slide rail and guides the slide of the temporary scaffold unit, and projects toward the temporary scaffold unit, and the supported portion is placed on the temporary structure. A support bracket that supports the scaffold unit, and the support bracket is rotatably provided around a rotation axis extending in a horizontal direction, and the outer wall surface With the rotation from the horizontal state of being flared perpendicularly to a direction to lower the tip is restricted for, turning in the direction to raise the front end from the horizontal state is characterized by being allowed.

  In the slide scaffold equipment, the temporary scaffold unit is supported by the support structure fixed to the outer wall surface, and the temporary scaffold unit is installed along the outer wall surface of the structure. When climbing the slide scaffold equipment, first, a support structure including a guide and a support bracket is installed in advance on the upper floor portion. At this time, the guide is engaged with the slide rail of the temporary scaffold unit, and the support bracket is in a horizontal state projecting perpendicularly to the outer wall surface. Next, the temporary scaffold unit is lifted and lifted by, for example, a lifting machine. Thereby, the supported part of the temporary scaffold unit placed on the support bracket of the support structure is separated from the support bracket. When the temporary scaffold unit is raised, the supported portion comes into contact with the lower surface of the support bracket of the support structure of the upper floor portion. At this time, since the support bracket is allowed to rotate in the direction of raising the tip from the horizontal state, the support bracket is pushed up by the ascending supported portion and rotates upward from the horizontal state. Then, when the supported portion moves above the tip of the support bracket and the supported portion is detached from the support bracket, the pushed-up support bracket rotates in a direction to lower the tip. At this time, since the rotation of the support bracket in the direction of lowering the tip from the horizontal state is restricted, the support bracket stops rotating when it becomes the horizontal state and returns to the original state. In this way, the supported portion of the temporary scaffold unit is lifted up over the support bracket of the upper floor portion. Next, the temporary scaffold unit is lowered and the supported portion is placed on the support bracket of the upper floor portion. At this time, since the support bracket is restricted from turning in the direction of lowering the tip from the horizontal state, the temporary scaffold unit is supported by the support structure of the upper floor portion. As described above, the slide scaffold equipment is replaced with the upper floor.

  In the slide scaffold facility according to the present invention, it is preferable that a sliding contact portion that is in sliding contact with the guide is attached to the slide rail.

  Thus, the temporary scaffold unit (slide rail) is raised while the sliding contact portion slides on the surface of the guide.

  In the slide scaffold facility according to the present invention, it is preferable that the support structure is provided with a clamp that is detachably attached to the slide rail.

  Thus, after the supported portion of the temporary scaffold unit is placed on the support bracket, the clamp is attached to the slide rail, and the support structure and the temporary scaffold unit are connected. Further, when climbing the slide scaffold equipment, the clamp is removed from the slide rail before raising the temporary scaffold unit.

  In the slide scaffold equipment according to the present invention, the clamp is provided in a clamp bracket extended toward the temporary scaffold unit, and the clamp bracket is provided to be rotatable along a vertical plane. Is preferred.

  Thereby, after removing a clamp from a slide rail, a clamp is released from the vicinity of a slide rail by rotating the clamp bracket extended toward the temporary scaffold unit side. Moreover, after raising the temporary scaffold unit, the clamp bracket is rotated to return to the original position (the state extended toward the temporary scaffold unit), and the clamp is attached to the slide rail.

  According to the slide scaffold equipment according to the present invention, when the climbing is performed, the support bracket rotates upward to dodge the supported portion of the temporary scaffold unit, so that the refilling operation can be easily performed.

  Next, a climbing method of the slide scaffold equipment 1 having the above-described configuration will be described.

  First, after the completion of the PC work for the n-1 floor pillar C and the outer wall W and the housing work for the nth floor slab S and the beam G shown in FIG. Is installed. Specifically, as shown in FIGS. 1, 3, and 4, first, an insert I for fixing the support metal fitting 3 is embedded in advance in the upper end portion of the outer wall W of the n−1 floor. . And after attaching the support metal fitting 3 to the slide rail 5 so that the guide 8 provided in the support metal fitting 3 may be covered from the upper end of the single pipe 51B on the outer wall surface X1, the support metal fitting 3 is moved along the slide rail 5. To the position of the upper end portion of the outer wall W of the (n-1) th floor. Next, the base plate 60 of the support fitting 3 is brought into contact with the outer wall surface X1, and the long hole 60a of the base plate 60 is aligned with the position of the insert I described above. Then, the bolt B is inserted through the long hole 60a of the base plate 60, screwed into the insert I, and tightened. Thereby, the base 6 (support metal fitting 3) is fixed to the outer wall surface X1. At this time, the support bracket 7 is in a horizontal state extending perpendicularly to the outer wall surface X1, and the single pipe 51B on the outer wall surface X1 side is passed between the pair of bracket plates 70, 70. Yes. In addition, the clamp 90 is not attached to the slide rail 5, and the clamp arm 9 is left hanging below the cylindrical portion 61. That is, the clamp arm 9 is disposed in parallel with the slide rail 5 between the slide rail 5 and the outer wall surface X1.

  Moreover, while removing the clamp 90 of the support metal fitting 3 each installed in the upper part of the outer wall W of the n-2 floor and the upper part of the outer wall W of the n-3 floor shown in FIG. Then, it is pulled out from the long hole 92 a of the pair of vertical wall portions 92, 92 and from the pin hole 91 b of the clamp bracket 91. As a result, the clamp bracket 91 is rotated in the direction of lowering the tip due to its own weight and is hung below the cylindrical portion 61, and is disposed in parallel with the slide rail 5 between the slide rail 5 and the outer wall surface X1. Is done. As a result, the clamp 90 is separated from the vicinity of the slide rail 5.

  Next, the temporary scaffold unit 2 is lifted by lifting the temporary scaffold unit 2 using a lifting machine such as a crane. As a result, the supported plate 56 is separated from the upper part of the support bracket 7 of the support fitting 3 installed on the upper part of the outer wall W of the n-2 floor and the upper part of the outer wall W of the n-3 floor. When the temporary scaffold unit 2 is lifted, the slide rail 5 is guided by the guide 8 as shown in FIG. 8, so that the temporary scaffold unit 2 moves upward along the outer wall surface X1. Further, the temporary scaffold unit 2 is raised while the sliding contact portion 58 attached to the slide rail 5 slides on the inner peripheral surface of the guide 8.

  Further, as described above, when the temporary scaffolding unit 2 is raised, the upper supported plate 56 is attached to the support metal 3 newly installed on the upper part of the outer wall W of the n-1 floor (the upper part of the outer wall W of the n-1 floor). The lower supported plate 56 is in contact with the lower surface of the support bracket 7 of the support bracket 3 installed on the outer wall W of the n-2 floor. Touch. At this time, since the support bracket 7 is allowed to rotate in the direction of raising the tip from the horizontal state, as shown in FIGS. Rotate upward. Then, as shown in FIG. 11, when the supported plate 56 moves above the tip of the support bracket 7 and the supported plate 56 is detached from the support bracket 7, the pushed-up support bracket 7 is moved from its center of gravity position. Since it is also provided so as to be rotatable around the rotation shaft 72 disposed on the base end side, it rotates in the direction of lowering the tip due to its own weight. Since the rotation of the support bracket 7 in the direction of lowering the tip from the horizontal state is restricted by the rotation restricting plate 73, the support bracket 7 stops rotating when the horizontal state shown in FIG. 11 is reached, and returns to the original state. In this manner, the supported plate 56 of the temporary scaffold unit 2 moves up by passing the horizontal support bracket 7.

  Next, as shown in FIG. 12, the temporary scaffold unit 2 is lowered, and the upper supported plate 56 is placed on the support bracket 7 of the support bracket 3 newly installed on the upper portion of the outer wall W on the n-1 floor. At the same time, the lower supported plate 56 is placed on the support bracket 7 of the support fitting 3 installed on the upper part of the outer wall W on the (n-2) th floor. At this time, since the support bracket 7 is restricted from rotating in the direction of lowering the tip from the horizontal state, the temporary scaffold unit 2 includes the support brackets 3 and n newly installed on the upper portion of the outer wall W on the (n-1) th floor. -Supported by the support fitting 3 installed on the upper part of the outer wall W on the second floor.

  Next, as shown in FIG. 13, the clamp bracket 91 of the support metal 3 newly installed on the outer wall W of the (n-1) th floor, and the clamp bracket of the support metal 3 installed on the upper of the outer wall W of the (n-2) th floor. Each of the 91 is rotated to bring the clamp arm 9 of each support fitting 3 into a horizontal state. Then, the clamp 90 of each support fitting 3 is attached to the single pipe 51B on the outer wall surface X1 side of the slide rail 5, and each support fitting 3 and the temporary scaffold unit 2 are connected.

Next, the support fitting 3 installed on the outer wall W of the n-3 floor is removed. If it demonstrates concretely, the volt | bolt B which has fixed the base plate 60 of the said support metal fitting 3 will be removed, and the support metal fitting 3 will be removed from the outer wall surface X1. Thereafter, the support fitting 3 is moved downward along the slide rail 5, and the support fitting 3 is removed from the slide rail 5 so that the guide 8 is pulled out from the lower end of the single pipe 51B on the outer wall surface X1 side.
Thus, the climbing of the slide scaffold facility 1 is completed.

  According to the slide scaffold equipment 1 having the above-described configuration, the climbing operation can be easily performed because the support bracket 7 rotates upward during the climbing to dodge the supported plate 56 of the temporary scaffold unit 2. That is, when climbing the slide scaffolding facility 1, the temporary scaffolding unit 2 can be raised while the support bracket 3 is installed on the outer wall surface X1, so that the trouble of removing and reattaching the support bracket 3 can be saved. .

  Further, the slide rail 5 is provided with a sliding contact portion 58 that is in sliding contact with the inner peripheral surface of the guide 8. When the temporary scaffold unit 2 is raised, the sliding contact portion 58 slides on the inner peripheral surface of the guide 8. Therefore, the interference between the slide rail 5 and the guide 8 can be prevented, and the temporary scaffold unit 2 can be raised smoothly.

  The support fitting 3 is provided with a clamp 90 that is detachably attached to the slide rail 5. After the supported plate 56 of the temporary scaffold unit 2 is placed on the support bracket 7, the clamp 90 is slid. By attaching to the rail 5, the support bracket 3 and the temporary scaffold unit 2 are connected to each other, so that the temporary scaffold unit 2 supported by the support bracket 3 is prevented from being unexpectedly detached from the support bracket 3 due to an earthquake or wind. can do.

  Further, since the clamp 90 is fixed to the tip of the clamp bracket 91 that can rotate along the vertical plane, the tip 90 is lowered when the clamp 90 is removed from the slide rail 5 and the temporary scaffold unit 2 is raised. Since the clamp 90 is separated from the vicinity of the slide rail 5 by rotating the clamp bracket 91, the interference between the clamp 90 and the slide rail 5 when raising the temporary scaffold unit 2 can be prevented. 2 can be raised smoothly.

As mentioned above, although embodiment of the slide scaffold installation concerning this invention was described, this invention is not limited to above-described embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, in the above-described embodiment, the temporary scaffold unit 2 including the framework scaffold 4 is provided. However, the present invention is not limited to the framework scaffold 4, and the temporary scaffold including the single pipe scaffold and other scaffolds. It may be a scaffold unit.

  In the above-described embodiment, the rotation shaft 72 of the support bracket 7 is disposed on the outer wall surface X1 side with respect to the center of gravity of the support bracket 7, and the support bracket 7 pushed up by the supported plate 56 is covered. When the support bracket 56 is detached from the support plate 56, the support bracket 7 rotates in the direction of lowering the tip by its own weight and returns to the original horizontal state, but the present invention is not limited to this. For example, the rotation shaft 72 of the support bracket 7 may be disposed at the center of gravity of the support bracket 7, or the support bracket 7 that is pushed up may return to the original horizontal state by the bias of a spring or the like. Good.

  In the above-described embodiment, the rotation restricting plate 73 for restricting the rotation of the support bracket 7 is provided above the base end portion of the support bracket 7. However, the present invention is not limited to this. . For example, the rotation restricting plate 73 may be provided below the front end portion of the support bracket 7 (the portion closer to the temporary scaffold unit 2 than the rotation shaft 72). Furthermore, when the support bracket 7 is in a horizontal state without providing the rotation restricting plate 73, the upper end of the guide 8 and the upper end of the front wall portion 63 of the cylindrical portion 61 come into contact with the lower surface of the distal end portion of the support bracket 7. A configuration is also possible.

  Further, in the above-described embodiment, the clamp 90 is fixed to the tip of the clamp bracket 91 that can rotate along the vertical plane. However, the present invention does not include the clamp bracket 91 and the clamp 90 is the base. 6 (cylinder portion 61) may be directly provided. For example, the clamp 90 may be configured to be detachably attached to the cylindrical portion 61. In this case, when the temporary scaffold unit 2 is raised, the clamp 90 is removed from the slide rail 5 and also from the support bracket 3. Remove.
