Description

  TECHNICAL FIELD The present invention relates to a technology for a lifting / lowering trap used for lifting / lowering between a building such as an apartment house or a building and a temporary scaffolding arranged in parallel to the building.

  Conventionally, a general ladder, which is a known technique, may be used for moving up and down between a building such as an apartment house or a building and a temporary scaffolding arranged in parallel with the building.

  However, when a general ladder is used, there is no fixing means for the building or the temporary scaffold, so the ladder installation becomes unstable, and the elevator moves smoothly between the building and the temporary scaffold. There was a problem that I could not.

  On the other hand, as in the technique described in Patent Document 1, for example, a ladder configured to be mountable on a truck bed frame is used for moving up and down between a building and a temporary scaffold (diversion). In such a case, since the installation of the ladder is stable, it is possible to smoothly move up and down between the building and the temporary scaffold.

  Next, the assembly structure of the raising / lowering trap 100 by the frame part 20, the ladder part 40, and the stage part 50 is demonstrated using FIG.6 and FIG.7.

  Below, the assembly structure of the ladder part 40 and the frame part 20 is demonstrated.

  The ladder part 40 is slidably assembled to the frame part 20. More specifically, in the ladder portion 40, the left vertical member 41 and the right vertical member 42 are inserted into the left vertical member frame 21 and the right vertical member frame 22 of the frame portion 20, respectively. The left vertical member 41 and the right vertical member 42 of the ladder part 40 are configured to be slidable in the vertical direction (longitudinal direction) inside the left vertical member frame 21 and the right vertical member frame 22 of the frame part 20, respectively. Is done.

  FIG. 6 shows the lifting and lowering trap 100 in a state where it is not used (hereinafter simply referred to as “non-use state”) (a state where it is not assembled). As described above, when the lifting / lowering trap 100 is not in use, substantially all of the left vertical member 41 and the right vertical member 42 of the ladder unit 40 are inserted into the frame unit 20, and the frame unit 20 and the ladder unit 40 are in front. The positional relationship is substantially overlapping visually. That is, when the lifting / lowering trap 100 is not in use, the longitudinal lengths of the assembled frame portion 20 and the ladder portion 40 are substantially the same as the longitudinal length of the frame portion 20 (or the ladder portion 40). It becomes.

  Thus, when the lifting / lowering trap 100 is not in use, almost all of the left vertical member 41 and the right vertical member 42 of the ladder unit 40 are inserted into the frame unit 20. There is no need to provide it, and the elevating trap 100 can be made compact and stored in a small space. That is, the cost can be reduced and the space can be effectively used.

  FIG. 7 shows an elevating trap 100 in a used state (hereinafter simply referred to as “used state”) (assembled state). When the lifting / lowering trap 100 is in use, the hook 27 of the frame portion 20 is not locked to the second pipe 12b (see FIG. 8), and the clamp 25 is disposed on the temporary scaffold 10 in the first pipe 12a. It will be in the state supported so that it could rotate freely. When the elevating trap 100 is in use, the frame portion 20 and the ladder portion 40 are rotated counterclockwise in a side view, and are inclined such that the upper side is the front and the lower side is the rear.

  As described above, when the elevating trap 100 is in use, substantially all of the left vertical member 41 and the right vertical member 42 of the ladder unit 40 are not inserted into the frame unit 20 (exposed from the frame unit 20). The lower end portion of the frame portion 20 and the upper end portion of the ladder portion 40 are in a positional relationship that substantially overlaps in front view. That is, when the lifting / lowering trap 100 is in use, the longest length in the longitudinal direction of the assembled frame portion 20 and the ladder portion 40 is the length in the longitudinal direction of each of the frame portion 20 and the ladder portion 40. It is almost the same as the added length.

  When the lifting / lowering trap 100 is not in use, it is formed at the top of the first insertion hole 28 of the left vertical member frame 21 of the frame part 20 and the plurality of insertion holes 44 of the left vertical member 41 of the ladder part 40. A toggle pin (not shown) is inserted through the insertion hole 44. As a result, the mutual positional relationship between the frame portion 20 and the ladder portion 40 is maintained (fixed) when the lifting trap 100 is not in use (the ladder portion 40 does not slide downward relative to the frame portion 20). ).

  Moreover, when the raising / lowering trap 100 is in use, the lower end part of the ladder part 40 is in contact with the floor surface of the balcony 2 of the building 1 (see FIG. 9B). That is, since the frame part 20 and the ladder part 40 are not fixed by the toggle pin, the ladder part 40 is slidable with respect to the frame part 20 and the floor surface of the balcony 2 located on the lower side in the longitudinal direction by its own weight. Press. As a result, the mutual positional relationship between the frame portion 20 and the ladder portion 40 in the use state of the elevating trap 100 is maintained (fixed) (the ladder portion 40 does not slide downward relative to the frame portion 20). .

  In addition, when the raising / lowering trap 100 is in use, the toggle pin can be inserted into the second insertion hole 29 of the left vertical member frame 21 of the frame portion 20 and the arbitrary insertion hole 44 of the left vertical member 41. As a result, the length of the ladder part 40 exposed downward without being inserted into the frame part 20 is adjusted in a plurality of stages when the lifting / lowering trap 100 is in use, and the lower end part of the ladder part 40 is adjusted to the balcony 2. It can be separated from the floor surface by an arbitrary height. Accordingly, for example, when the ladder 40 becomes an obstacle when an operator works, the ladder 40 is separated from the floor surface of the balcony 2 by an arbitrary height so that the ladder 40 can be operated. It can prevent getting in the way.

  Below, the assembly | attachment structure of the stage part 50 and the frame part 20 is demonstrated.

  The stage unit 50 is rotatably assembled to the frame unit 20 and is configured to be housed in the stage housing unit 26 of the frame unit 20. In the stage unit 50, a stage support unit 52 is rotatably connected to the support unit 30 of the stage accommodating unit 26 of the frame unit 20 via a pin (not shown). As a result, the stage unit 50 is rotatably supported with respect to the frame unit 20.

  FIG. 6 shows the stage unit 50 in a state of being accommodated in the stage accommodating unit 26 of the frame unit 20 (in an unassembled state). Thus, in the state in which the stage unit 50 is accommodated, the stage unit 50 is arranged so that the stage locking unit 53 (tip portion) is directed upward and along the longitudinal direction of the frame unit 20. . That is, in a state where the stage unit 50 is accommodated, the stage unit 50 and the frame unit 20 can be assembled in a compact manner.

  FIG. 7 shows the stage unit 50 in a used state (not accommodated) (assembled state). Thus, in a state where the stage unit 50 is used, the stage unit 50 rotates counterclockwise in a side view, and the stage locking unit 53 (tip portion) is directed forward. . In such a case, the stage unit 50 is in a state in which the stage plate material 51 has the plate surface directed in the vertical direction.

  Next, the assembly method of the raising / lowering trap 100 from a non-use state to a use state is demonstrated using FIG.8 and FIG.9.

  As shown in FIG. 8A, the lifting / lowering trap 100 is attached to the temporary scaffold 10 in a state where the longitudinal direction is directed in the vertical direction when not in use. In this state, the hooking tool 27 of the frame portion 20 is locked to the second pipe 12b. As a result, the lifting / lowering trap 100 is configured not to rotate freely (regardless of the operator's intention).

  In this manner, the lifting / lowering trap 100 can be stored in the temporary scaffold 10 when not in use. Therefore, the elevating trap 100 can be prevented from interfering with the operator's work when not in use. Further, the lifting / lowering trap 100 may be attached to the temporary scaffold 10 in a non-use state, and it is not necessary to provide a storage place dedicated to the lifting / lowering trap 100. That is, the cost can be reduced and the space can be effectively used.

  Next, as shown in FIG. 8B, the lifting / lowering trap 100 is rotated counterclockwise in a side view by removing the hook 27 of the frame portion 20 from the second pipe 12b.

  Next, as shown in FIG. 9A, the stage unit 50 is removed from the holding unit 31 of the frame unit 20 and rotated counterclockwise in a side view. And the stage latching | locking part 53 formed in the front-end | tip part of the stage part 50 is latched by the 2nd pipe 12b from upper direction. As a result, the posture of the frame portion 20 and the ladder portion 40 after being rotated (the posture inclined such that the upper side is the front and the lower side is the rear) is maintained (fixed).

  Next, as shown in FIG. 9B, the ladder portion 40 is slid with respect to the frame portion 20 and lowered downward. That is, the left vertical member 41 and the right vertical member 42 of the ladder unit 40, which are almost entirely inserted inside the frame unit 20, are exposed to the outside of the frame unit 20. In this case, since a gap S is formed in the lower cross member 24 of the frame portion 20, the operator's hand is sandwiched between the cross beam 43 of the ladder portion 40 and the lower cross member 24. Can be prevented. Further, the retaining plate 45 of the ladder part 40 is configured to interfere with the lower cross member 24 of the frame part 20 when the ladder part 40 descends most downward with respect to the frame part 20. As a result, the ladder portion 40 can be prevented from completely falling off from the frame portion 20.

  Using the liftable trap 100 assembled in this way, the worker can move up and down between the scaffold member 12 of the temporary scaffold 10 and the balcony 2 of the building 1.

  Further, when the worker moves from the scaffold member 12 of the temporary scaffold 10 to the balcony 2 of the building 1 using the lifting and lowering trap 100, the left vertical member frame 21 and the right vertical member frame 22 of the frame portion 20 It moves to the ladder part 40 side through the space. In such a case, the operator can use the left vertical member frame 21 and the right vertical member frame 22 arranged on the left and right sides as handrails. Thus, for example, even if the operator fluctuates on either the left or right side during movement, the left vertical member frame 21 or the right vertical member frame 22 can be gripped, so that the operator can move smoothly.

  Further, when the worker moves from the scaffold member 12 of the temporary scaffold 10 to the balcony 2 of the building 1 using the lifting / lowering trap 100, the worker moves the stage unit 50 with the plate surface of the stage plate member 51 facing up and down. Since it can be used as a scaffold, it can move smoothly.

  In addition, the raising / lowering trap 100 cannot be assembled from the balcony 2 side of the building 1 in a non-use state. More specifically, in a state in which the elevating trap 100 is installed, the lifting / lowering trap 100 is inserted into the first insertion hole 28 of the frame portion 20 and the insertion hole 44 (formed at the top of the plurality of insertion holes 44) of the ladder portion 40. The toggle pin is configured so that it cannot be removed from the balcony 2 side of the building 1. That is, the lifting / lowering trap 100 can be prevented from being assembled by a person other than the operator by mischief or the like and being moved from the balcony 2 of the building 1 to the temporary scaffold 10 in a non-use state.

  Moreover, when the temporary scaffold 10 is assembled, the raising / lowering trap 100 can be installed simultaneously with the assembly of the temporary scaffold 10. Therefore, the assembly work of the temporary scaffold 10 and the installation work of the lifting / lowering trap 100 can be performed at the same time without being performed separately, so that work efficiency can be improved.
