Description

  The present invention relates to a scaffolding plate slide preventing member that prevents sliding of a scaffolding plate used in a work scaffold of a temporary structure.

  In a temporary structure framed to perform work at a high place, a scaffolding plate is constructed by horizontally spanning a scaffolding plate between single pipes serving as frame portions. Since this scaffold plate is dangerous when slid on the single pipe during work, it is fixed to the single pipe using a locking tool including bolts, nuts, and the like (see, for example, Patent Document 1).

  Further, as shown in FIGS. 9 and 10, a scaffolding plate slide preventing member 21 and the like are also used for preventing the scaffolding plate from sliding. The scaffolding plate slide prevention member 21 includes a resin-made inner holding member 22 configured in an annular band attached to the outer peripheral surface of the single tube 27, and the inner holding member 22 from the outer peripheral surface side to the core of the single tube 27. And a metal outer pressing member 25 configured in a ring shape to be pressed to the part side.

  As shown in FIGS. 9 and 10, the outer pressing member 25 is connected to the inner holding member 22 on the base end side through the hinge portion 24. In addition, a locking portion 26 that is locked to the convex portion 23 on the distal end side of the inner holding member 22 is provided on the distal end side of the outer pressing member 25.

  When this scaffolding plate slide preventing member 21 is applied, the scaffolding plate having a structure in which a pair of hook-shaped bridging portions are formed at both ends in the longitudinal direction is mainly used. That is, by mounting two or more scaffolding plate slide prevention members 21 at predetermined positions in the vicinity of the bridging portion in a state where the scaffolding plates are bridged between the single pipes 27 through a total of four bridging portions. In both the one and the other sliding directions, the scaffolding plate slide preventing member 21 functions as a stopper that abuts on the bridge portion and the side surface, thereby preventing the scaffolding plate from sliding.

  However, since such a scaffolding plate slide prevention member 21 has a relatively complicated structure in which two types of parts made of different materials are connected via a hinge mechanism, it is a high-priced part. Further, as described above, the scaffold board slide prevention member 21 is provided for one scaffold board in order to prevent the scaffold board from sliding in both sliding directions (one and the other) along the longitudinal direction of the single tube. Therefore, it is necessary to mount at least two scaffold plate slide prevention members 21. For this reason, there is a problem in terms of manufacturing cost.

  Further, as described above, in addition to the necessity to attach a plurality of scaffolding plate slide prevention members 21 to one scaffolding plate, after the inner holding member 22 is attached to a single pipe, the inner holding member is further attached. Since it is necessary to latch the latching | locking part 26 of the outer side pressing member 25 in the convex part 23 of 22, the improvement of workability | operativity at the time of attachment is also calculated | required.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a scaffolding plate slide prevention member that can reduce manufacturing costs and improve workability during attachment.

In order to achieve the above object, the scaffold plate slide prevention member of the present invention has a hook-shaped bridging portion between both ends between a pair of single pipes facing each other extending in the horizontal direction of the temporary structure. A scaffolding plate slide preventing member for preventing the scaffolding plate placed so as to be bridged over the peripheral surface of the single tube at a position facing each other across the spanning portion from the longitudinal direction of the single tube A pair of hook-shaped stopper portions that are mounted while bending an inner diameter portion thereof, and are arranged to face each other with a space therebetween, and the pair of stoppers straddling the bridging portion from the longitudinal direction of the single tube A pair of U-shaped handle portions that connect the portions to each other, and the pair of stopper portions have their tip portions bent to the other stopper portions facing each other, and further Stopper part and The pair of handle portions are constituted of a material coated with a resin or rubber on the surface of the metallic base material, characterized by a crotch.

  In the present invention, in a state where the scaffolding plate is horizontally bridged between the single tubes via the bridging portion, at least one scaffolding plate slide preventing member is prepared, and the operator handles the handle portion. By mounting the pair of stopper portions at respective positions facing each other across the bridging portion on the peripheral surface of the single tube, the scaffold plate can be prevented from sliding.

  That is, in both one and the other sliding direction of the scaffolding plate along the longitudinal direction of the single tube, each of the pair of stopper portions of the single scaffolding plate slide prevention member can come into contact with the spanning portion and the side surface, This prevents the scaffold plate from sliding.

  Therefore, according to this scaffold board slide prevention member, the component unit price required for the slide prevention of one scaffold board can be reduced substantially. Moreover, in this scaffold board slide prevention member, since attachment work is completed only by attaching each stopper part to a single pipe surrounding surface, holding a handle part, workability | operativity at the time of attachment can be improved. Furthermore, since this scaffold board slide prevention member is implement | achieved by the comparatively simple structure of connecting a pair of stopper part with a handle part, it can aim at reduction of manufacturing cost.

Hereinafter, embodiments will be described with reference to the drawings.
As shown in FIGS. 1 to 5, the scaffolding plate slide preventing member 1 of the present embodiment is a temporary structure framed to perform work at a high place, etc., and is a single pipe (annular iron pipe) serving as a frame portion. ) It is used in a work scaffold constructed by linking the scaffolding plate 12 between 14 in a horizontal direction. As shown in FIGS. 3 and 5, the temporary structure is framed in a lattice shape by connecting the single tubes 14 vertically and horizontally via the single tube connecting member 16.

  As shown in FIG. 1 to FIG. 4, the scaffolding plate slide prevention member 1 is dangerous when the scaffolding plate 12 slides on the single tube 14 during work. This is to prevent the scaffold plate 12 placed so as to be bridged between the single tubes 14 from sliding in the directions of the arrows E and F (see FIGS. 3 and 6).

  A pair of hook-shaped (cross-sectional C-shaped) bridging portions 15 are formed at both ends in the longitudinal direction of the scaffold plate 12. That is, the scaffolding plate 12 is bridged in the horizontal direction between the single tubes 14 via a total of four bridging portions 15.

  In order to prevent such sliding (sliding) of the scaffolding plate 12, the scaffolding plate slide preventing member 1 includes a handle portion 2 composed of two rod-shaped portions and a pair of pairs as shown in FIGS. A hook-shaped stopper portion 3, a joint portion 7, and a bent portion 5 are mainly provided.

  The scaffolding plate slide preventing member 1 is made of a metal material that can be elastically deformed (bendable) by artificial pressure. The joint portion 7 is a portion where each stopper portion 3 and each handle portion 2 are joined by welding or the like. The bent portion 5 is configured by bending the four tip end portions of the pair of hook-shaped stopper portions 3 toward the other stopper portions facing each other.

  After the joint portion 7 and the bent portion 5 are formed, the entire base metal surface including the stopper portion 3 and the handle portion 2 is coated with resin or rubber by dipping to obtain the scaffold plate slide prevention member 1. It is done.

  Each of the stopper portions 3 is formed in a C-shaped cross section as shown in FIGS. 1, 4, and 6, and at a position facing each other across the bridging portion 15 from the longitudinal direction of the single tube 14. The tube 14 is mounted while being bent (elastically deformed) with respect to the outer peripheral surface of the tube 14. The (two) handle portions 2 connect the pair of stopper portions 3 in a crank shape across the bridging portion 15 from the longitudinal direction of the single tube 14.

  Here, the resin on the surface of the scaffolding plate slide prevention member 1 described above is for preventing the displacement of the stopper portion 3 with respect to the peripheral surface of the single tube 14 in a state where the stopper portion 3 is mounted on the peripheral surface of the single tube 14. Coated to obtain frictional force. 1 and 2 is provided as a mounting guide for suppressing galling at the tip of the stopper when the stopper 3 is mounted on the peripheral surface of the single tube 14.

  In the present embodiment, at least one scaffolding plate slide preventing member 1 is prepared in a state where the scaffolding plate 12 is horizontally bridged between the single tubes 14 via the bridging portion 15, and the operator handles As shown in FIGS. 3 and 5, the pair of stopper portions 3 are mounted at positions facing each other across the bridging portion 15 on the peripheral surface of the single tube 14 while holding the portion 2. It is possible to prevent the scaffolding plate 12 from sliding in the direction of the arrow E and the direction of the arrow F during the work at the time.

  That is, in this embodiment, as shown in FIG. 6, the single scaffolding plate slide prevention member 1 in both sliding directions of the arrow E direction and the arrow F direction with respect to the scaffolding plate 12 along the longitudinal direction of the single tube 14. Each of the pair of stopper portions 3 can come into contact with the bridging portion 15 on the side surface, thereby preventing the scaffold plate 12 from sliding.

  Therefore, according to the scaffolding plate slide prevention member 1, the single scaffolding plate slide prevention member 1 can prevent the scaffolding plate 12 from sliding, so that the cost of parts necessary for preventing the sliding of one scaffolding plate can be substantially reduced. Is possible. Furthermore, according to this scaffolding plate slide prevention member 1, the attachment work is completed simply by attaching each stopper part 3 to the peripheral surface of the single tube 14 while holding the handle part 2, thereby improving workability at the time of attachment. Can be made. Moreover, since the scaffold board slide prevention member 1 is implement | achieved by the comparatively simple structure of connecting a pair of stopper parts 3 with the handle part 2, reduction of manufacturing cost can be anticipated.

  Although the embodiment has been described above, the above-described embodiment is an exemplification, and the embodiment is not limited to the embodiment, and may be appropriately changed. For example, as shown in FIG. 6, the same slide prevention effect can be obtained even when the scaffolding plate slide prevention member 1 is mounted from either the top or the bottom of the single tube 14. In addition, when the scaffolding plate slide prevention member 1 is mounted at each position where the pair of stoppers 3 face each other across the bridging portion 15 on the circumferential surface of the single tube 14, two scaffolding plate slides are provided for one scaffolding plate. The prevention member 1 may be attached.
