Description

The present invention relates to supporting jig you support vertical posts to be used when such is provided a case or panel Crossed another scaffold on hanging scaffold.

Suspended scaffolding with a large number of scaffolding panels connected is used for construction at high places. As a scaffolding panel, there is one in which the applicant has previously obtained a patent right (Patent Document 1).

As shown in FIG. 6, the scaffolding panel A has a rectangular scaffolding plate (for example, metal) on the upper surface of a peripheral frame provided with two elongated lumbers B, two connecting pipes (frame pipes) C, and a reinforcing material D. Flat plate, control panel material, expanded metal, or other scaffolding board) E is arranged and fixed. There is a gap F between the reinforcing material D on both ends in the longitudinal direction and the frame pipe C, and a locking material G connecting the reinforcing material D and the frame pipe C is provided between the reinforcing material D and the frame pipe C.

As shown in FIG. 7, the scaffolding panel A is suspended by being locked by a suspension chain I suspended from a frame (main girder) H of an elevated road, an iron bridge, or the like, and is suspended vertically and horizontally to connect the scaffolding panel A. Can be formed.

When working by installing a suspended scaffold, another scaffold may be built on the suspended scaffold. In addition, the suspended scaffold may be provided with panels, fences, nets, etc. (hereinafter referred to as "panels, etc.") used for various purposes such as fall prevention and daylighting.

Conventionally, when another scaffold, a panel, or the like is provided on the suspended scaffold, the floor plate J is installed on the suspended scaffold and the jack base K is arranged in the recess of the floor plate J as shown in FIGS. do. After that, the screw rod K1 of the jack base K was covered with a pipe-shaped vertical support L, and the scaffolding, the panel, and the like were installed using the vertical support L.

Japanese Patent No. 2647801

However, the conventional method has the following problems.
(1) Since the jack base K is not fixed to the scaffolding panel A, it lacks stability such as lateral displacement.
(2) Since the jack base K has to be installed on the scaffolding plate E which is a work space, the work space becomes narrow.
(3) When a steel cloth plate or the like is used as the scaffold to be installed on the suspended scaffold, it is necessary to install the jack bases in two rows in parallel as shown by the virtual line in FIG. 8 (b). In this case, the work space becomes even smaller.
(4) If there is a main girder that supports the floor slab above the suspended scaffolding, such as under a highway, the main girder may become an obstacle and the jack base K may not be installed in two rows ( FIG. 8 (b).

The present invention has been made in view of the above circumstances, the problem to be solved is excellent in stability as compared with the jack-based conventional mounting postfix expression, provides a supporting lifting device that can of ensuring a wide working space There is.

Supporting jig of the present invention is a supporting lifting device to use attached to the pipe of the scaffold panel having a pipe, a support shaft provided with a screw, a pipe provided scaffolding panel at the lower end of the support shaft It is equipped with a connectable clamp and an adjuster that is screwed around the outer circumference of the support shaft and can move in the longitudinal direction of the support shaft. When the clamp is connected to the pipe of the scaffold panel, the support shaft is perpendicular or substantially perpendicular to the scaffold panel. It is configured to stand in.

Supporting jig of the present invention, since they are connecting to the pipe scaffold, fear of skidding as jack-based conventional mounting postfix expression is excellent in stability without. Further, since it is fixed to the pipe of the scaffolding material, it is possible to secure a space on the scaffolding panel as a work space like a conventional mounting type jack base.

(Embodiment)
An example of embodiment of the supporting jig 10 of the present invention will be described with reference to FIGS. Supporting jig 10 of the present invention is for use in mounting to the pipe of the scaffold panel having a pipe. Here, the case where the scaffolding panel is a conventional scaffolding panel A (see FIG. 6) provided with a connecting pipe C is taken as an example, but the scaffolding panel may be other than this as long as it is provided with a pipe. In FIG. 1, 1 is a support shaft, 2 is a clamp, and 3 is an adjuster. The clamp 2 is fixed to one end side of the support shaft 1 by welding, and the adjuster 3 is screwed to the outer circumference of the support shaft 1.

The support shaft 1 is a vertically long rod-shaped member for covering the vertical support L on the support shaft 1. In this embodiment, a pipe material is used as the support shaft 1. Although a rod-shaped solid wood can be used for the support material 1, it is preferable to use a pipe material from the viewpoint of weight reduction. A male screw 1a is formed on the outer peripheral surface of the support shaft 1.

The clamp 2 is a member that holds the pipe of the scaffolding panel A. In this embodiment, an existing single tube clamp is used as the clamp 2. The clamp 2 is fixed to the lower end side of the support shaft 1 by a bolt. As shown in FIGS. 1 and 2 (a) and 2 (b), the clamp 2 includes a clamp body 2a attached to one end in the axial direction of the support shaft 1, an opening 2b that can be put on and removed from the connecting pipe C, and the like. An opening / closing tool 2c capable of opening / closing the opening 2b and a tightening tool (bolt and nut) 2d for fixing the opening / closing tool 2c to the clamp body 2a are provided.

The adjusting tool 3 is a member for adjusting the position of the vertical column L over the support shaft 1 in the height direction. As an example, the adjuster 3 shown in FIG. 1 has a ring shape, and a female screw 3a screwed into the male screw 1a of the support shaft 1 is formed on the inner peripheral surface. The adjusting tool 3 of this embodiment is provided with operating holes 3b at two locations in the circumferential direction. In this embodiment, as shown in FIG. 3B, when the operation rod M is inserted into the operation hole 3b and the operation rod M is rotated in the direction of the arrow in the drawing, the adjusting tool 3 causes the male screw 1a of the support shaft 1 to move. When the operating rod M inserted into the operating hole 3b is rotated in the direction opposite to the arrow, the adjusting tool 3 moves upward along the support shaft 1.

As shown in FIG. 2 (a) (b), supporting jig 10 of this embodiment, the clamp 2 is fixed to the connecting pipe C scaffold panels A constituting the hanging scaffold to the scaffold panel A by the fixed By covering the vertical support shaft L on the upright support shaft 1, the vertical support L can be supported in the vertical direction.

3 (a) is a supporting jig 10 mounted on the connecting pipe C of the scaffold panel A in the procedure, to secure the clamp 2 of this said supporting jig 10, covered with a vertical strut L onto the support shaft 1 It is a perspective view which shows the state. From this state, when the operating rod M is inserted into the operating hole 3b of the adjusting tool 3 and rotated in the direction of the arrow in the drawing as shown in FIG. 3B, the adjusting tool 3 descends while rotating, and the vertical support L The support position can be shifted downward. On the other hand, when the operation rod M inserted into the operation hole 3b is rotated in the opposite direction, the adjuster 3 rises while rotating, and the support position of the vertical support L can be shifted upward.
