Abstract

<P>PROBLEM TO BE SOLVED: To provide a building frame which facilitates holding of a gap interval between ledgers of a prefabricated scaffold. <P>SOLUTION: The building frame 1 has an anti-skid member set at least at one location of a horizontal member 2 thereof. The anti-skid member is formed of projections 3, or projective rings which are arranged at suitable intervals. Thus, work of holding the gap interval between the ledgers, or provision of binding wires for fixing the ledgers is dispensed with, and therefore scaffold assembling efficiency is improved. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a building frame used for a framework scaffold.

  As shown in FIG. 5, when the gap a between the cloth plates 13 becomes wide due to vibrations caused by the arrival and departure of the worker, the cloth scaffolding of the frame scaffolding causes objects to fall down or the operator's feet to be caught. Therefore, it is necessary to regulate (30 mm or less) so that it does not spread beyond a predetermined gap.

  Therefore, conventionally, a method of binding the hooks 15 of the cloth board 13 with the wire 14 is used. In this case, after laying the cloth board 13 on the building frame, the hook 15 is tied with a wire 15 having an appropriate length from the lower stage of the cloth board 13 by using a sino (pointed tool for binding wire) or the like. ing.

As another example, there is an invention of JP-A-2003-120021. This is known as a corrective hardware provided with a tension preventing portion such as a bolt and a screw attached to the side surface by hooking a hook for preventing the fall on the folded portion between the cloth plates.
JP 2003-120021 A

  However, in the above method using the number wires, it takes time to bind the number wires to the hooks, and it is necessary to prevent the number wires from protruding on the lower surface of the cloth plate so as not to disturb the operator. Also, after installing the cloth board, fastening the number wire at the lower stage was a separate work, and workability was poor. Moreover, it took time and effort to cut the number wire at the time of dismantling, and the shape of the number wire collapsed, making it difficult to remove. In addition, when the wire after cutting falls, there are many protrusions, which increases the degree of danger and increases the amount of industrial waste because it cannot be reused.

  In addition, the corrective hardware was troublesome because it was attached with bolts and the like, and the same work was required at the time of dismantling. Further, the bolts and the like may be loosened due to vibration or the like, and the maintainability is inferior.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a building frame that can easily maintain the gap interval between the cloth plates in the frame scaffold.

  The building frame according to the present invention is characterized in that a displacement preventing member is provided in at least one place in the horizontal member of the building frame. Further, the displacement preventing member is a protrusion or a protrusion-like ring, and includes that these are provided at an appropriate interval.

  Since work and jigs (such as wire numbers) for maintaining the gap spacing between the cloth plates are not required, the attachment, removal, adjustment, reworking, and the like can be omitted, and the scaffold assembly work can be made more efficient. In addition, parts and jigs (such as wire numbers) are not required to keep the gaps between the cloth plates, so that they can be prevented from falling and safe, and they are no longer disposed of as industrial waste. Be kind to you.

  Hereinafter, embodiments of the building frame of the present invention will be described with reference to the drawings. In the embodiments, the same components are described with the same reference numerals, and only different components are described with different reference numerals. This building frame is used for assembling the frame scaffolding, and the frame scaffolding is assembled by laying cloth plates on horizontal members between the building frames.

  FIG. 1 shows a building frame 1 according to the first embodiment, in which a lateral width is 900 mm and three cloth boards are installed. Two protrusions (a pair of protrusions with an appropriate interval) 3 are provided on the upper surface of the horizontal member 2 so that a gap between the cloth plates laid between the building frames does not widen. As shown in FIG. 2, the hook 5 of the cloth plate 4 on one side (the front side in the drawing) and the hook 7 of the cloth plate 6 on the other side are alternately hooked on the horizontal member 2 between the protrusions 3. The hook 5 of the cloth plate 4 on the near side is stopped by the right protrusion 3a in the drawing, and the hook 7 of the cloth plate 6 on the other side is stopped by the protrusion 3b on the left side in the drawing. The gap 8 between the cloth plates is prevented from widening.

  FIG. 3 shows the building frame 10 of the second embodiment, in which the width is 1200 mm and two cloth boards are installed. The upper surface of the horizontal member 2 of the building frame 10 is provided with one pair of projections 3 with an appropriate interval, and the other configuration is the same as that of the building frame 1 and has the same effects. Is. The number of protrusions 2 can be increased or decreased as necessary.

  FIG. 4 shows another embodiment. The misalignment prevention member may be a projecting ring 11 in addition to the projection 3, and any hook may be used as long as it does not deviate laterally.

It is the building frame of 1st Embodiment, (1) is a front view, (2) is a top view. (1) is a plan view in which a hook is hooked on a horizontal member, (2) is a perspective view thereof, and (3) is a sectional view thereof. It is a front view of the building frame of 2nd Embodiment. It is a front view of other embodiment. It is a perspective view which shows the fixing method of the conventional cloth board.
