Description

  The present invention is designed to fix the fasteners for the main pillar of the scaffolding for the purpose of easily and securely attaching the fasteners with handrails and braces attached to the vertical main pillars used for the temporary scaffolding at the construction site. It relates to the device.

  Conventionally, in assembling work and dismantling work of this type of temporary scaffold, the mounting bracket is attached to or removed from the main pillar. And, since the members such as handrails and streaks are sequentially attached to the mounting bracket and assembled and attached from the position reaching the upper floor, the work is very complicated and time consuming, and the members and the like fall down. It is the present situation that many falls of workers occur.

In the assembly procedure of the temporary scaffold in the conventional technique, as described above, after the main column is erected, the mounting bracket is fixed to the main column with a wedge or the like with respect to the main column, and the mounting bracket is handrailed. The task of determining the assembly position by lifting the streaks from the bottom in order. Therefore, since the work is very troublesome and complicated, it takes time and effort.
The present invention solves the conventional complicated and dangerous work and the mounting work of the mounting bracket to the main pillar which is very troublesome and inefficient, and the main purpose is to attach it to the scaffold main pillar It is an object of the present invention to provide a fastening device fixing device that can easily and securely fasten and remove a fastening tool that moves up and down and pivots up and down easily.

In order to achieve the above object, in the fastening device for fastening fasteners that can be raised and lowered on the scaffolding main pillar of the present invention and fixed at a predetermined position, the scaffolding pillar for temporary scaffolding is connected to the upper and lower sides and is attached to the outer periphery. Is provided with a receiving projection with a predetermined interval.
On the one side of the fastener, a movable portion that faces the fixed portion is formed. The fixed portion is provided with a fitting recess on the lower side, and the bearing portion is attached to the surface of the long piece attaching portion. An engagement key rod that can be moved up and down and turned is inserted into the bearing portion.
The engagement key rod is formed with a vertical rotation portion and a bent locking rod.
In addition, the movable part is configured to be fastened and fixed by attaching a tubular fitting or the like on the inner surface side of the attachment piece to which the bent engagement rod is fitted.

Since the present invention is configured as described above, the locking projections are attached to the outer periphery of the scaffolding main pillar with a predetermined interval, so that the handrails and the clamps (clamps) attached with the streak are free. There is an effect that it can be freely raised and lowered and easily fixed at a predetermined position of the main pillar. In addition, since the receiving protrusion is attached to the scaffolding main pillar, the mounting work of the bracket can be easily and safely visually attached to the receiving protrusion without using a scale or the like. There is also an effect that the handrail advance type scaffolding can be easily made by the fastener.
In addition, the one long piece attachment part of the fastener is fixed to the bearing part, and a bending engagement rod is inserted into the inside of the attachment part so as to be movable up and down. Thus, there is also a convenient effect that the fastener can be easily firmly fixed or released by raising and lowering and turning the folding latch.

  FIG. 3 is a side view of the scaffold main column of the present invention with a part of the open state in which a handrail portion and a stagger are attached to a fastener.   FIG. 6 is a perspective view of the scaffold main column of the present invention with a part of the fastening member fixed in place with an engagement key rod.   It is a top view of the tightening state of the fastener of the present invention.   It is the slope view which similarly inserted the engagement key rod into the bearing part of this invention so that raising / lowering was possible.

  The engagement key shown in FIG. 3 is formed after the fasteners attached to the scaffolding pillars constructed as described above are supported and fixed to the engagement recesses for locking on the receiving projections so that they can be moved up and down or turned up and down. As shown in FIG. 2, the heel is pivoted upward, and the bent locking rod is fitted and fixed to the locking bracket of the tubular body attached to the inside of the mounting piece, and the fastening bracket is firmly fixed to the scaffolding main column. It is to be attached.

  Next, an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, the scaffold main pillar (1) has a tubular body and is formed so that the upper and lower sides are connected to each other. The receiving protrusions (2), (2), etc. of various shapes that support the fastener (3) with a predetermined interval in the direction are attached and fixed.

2 to 4, the fastener (3) is wound around the scaffold main pillar (1) by a fixed part (5) and a movable part (6) that rotates, and the outer periphery. Rotate or move up and down.
The fixing portion (5) is formed with a fitting recess (9) that fits the receiving projection (2) on the lower side, and the long piece mounting portion (10) protruding on one side has a surface The bearing portion (11) is fixed to the inner side, and a rotatable engagement key rod (12) is erected up and down in the interior thereof. The engagement key rod (12) is formed with a vertically movable portion (13) that can be moved up and down and a bent locking rod (14) to be engaged.
Further, the movable part (6) opposed to the fixed part (5) is fixed in the vertical direction with a locking fitting (8) such as a tube on the inner surface of the mounting piece (7).

  Further, a rotating handrail portion (17) is attached to the long piece attachment portion (10) shown in FIG. 1, and attached to the adjacent scaffold main pillar (1) at the tip of the handrail portion (17). A latch (16) that engages with a locking recess (15) provided on the fastening bracket (3) is connected. A string difference (18) is connected to the latch (16). In addition, the difference of a code | symbol (19) is connected with a part of this long piece attaching part (10).
