Description

  The present invention relates to a scaffold bracket used for a scaffold on one side in a temporary scaffold assembled at a construction site or the like.

  Conventionally, a temporary scaffold is provided along a building such as a building at a construction site, and is used by a site worker to perform construction such as repairing the building. As a temporary scaffold, for example, a wedge-type scaffold in which a long wedge is used when connecting members is known. Among these wedge-tight scaffolds, a bracket one-side scaffold is known in which a scaffold plate is laid using a scaffold bracket (see, for example, Patent Document 1).

  FIG. 6 is a perspective view showing an example of a scaffold bracket 21 (hereinafter simply referred to as “bracket 21”) used in a conventional bracket one-side scaffold. The bracket 21 is attached to a plurality of support posts 22 erected along a building not shown. The bracket 21 is provided with a horizontal member 25 having a connecting member 24 provided at both ends so that a substantially U-shaped wedge 23 can be inserted and fitted.

  The bracket 21 is supported by connecting one end of a horizontal member 25 of the bracket 21 to a flange 26 formed on the support column 1 by a connecting member 24 and a wedge 23. A scaffolding plate 27 is laid between the adjacent brackets 21 so as to span the horizontal members 25. As shown in FIG. 7, the scaffold plate 27 is fixed to the bracket 21 by overlapping an end portion with another scaffold plate 27 and binding the overlapped portion with a wire 28 or a rubber band.

  However, in the bracket 21, the scaffold plate 27 is only bound by the wire 28 or the like. Therefore, when the field worker walks on the scaffold plate 27 in such a state, the scaffold plate 27 is outside (the support column). The scaffold plate 27 may fall off the bracket 21 in some cases.

  Therefore, conventionally, as shown in FIG. 8, the length of the wedge 29 inserted into the connecting member 24 at the other end is made longer than the conventional one so that the upper portion of the wedge 29 protrudes by a predetermined amount from the connecting member 24. . Thereby, it is possible to prevent the scaffold plate 27 from being shifted outward by the wedge 29, and to prevent the scaffold plate 27 from falling off.

  However, in the conventional bracket 21, the wedge 29 protrudes from the connecting member 24 by a predetermined amount. For example, when the bracket 21 is transported, the wedge 29 may collide with another obstacle and be damaged or deformed. is there. Further, since the wedge 29 is long, there is a problem that it is difficult to handle the bracket 21 when the bracket 21 is packed or when the bracket one-side scaffold is assembled or disassembled.

  Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

  FIG. 1 is a perspective view showing a bracket one-side scaffold to which a bracket for a scaffold according to the present invention (hereinafter simply referred to as “bracket”) is applied. FIG. 2 is a perspective view of the bracket shown in FIG.

  The bracket one-side scaffold is used, for example, at a construction site of a general house, and a plurality of support columns 1 are erected. The support columns 1 are provided at predetermined intervals along the outer surface of the building (not shown). A handrail 2 and a lower arm 3 for supporting each column 1 are connected between adjacent columns 1. In FIG. 1, an unillustrated building is provided on the front side. Moreover, in the bracket one side scaffold shown in FIG. 1, the two support | pillars 1 arranged in parallel with the direction which goes to a building, and the one support | pillar 1 are standingly arranged by turns for every span.

  Each support column 1 is formed with a plurality of flanges 4 at predetermined intervals in the vertical direction. As shown in FIG. 2, each flange 4 is formed with four retaining holes 4 a for allowing each member such as the handrail 2 and the lower arm 3 to be connected in four directions. A connecting member 11 and a wedge 12 (to be described later) are connected to these retaining holes 4a in order to fix one end portions of the handrail 2, the lower arm 3, and the like. In FIG. 2, the scaffolding plate 6 is omitted for convenience of explanation.

  A plurality of brackets 5 are attached to the column 1. The bracket 5 is for laying a scaffold plate 6 that extends in a direction toward the building and is a plate material having a substantially rectangular shape in plan view (see FIG. 3). The scaffolding plate 6 is for a field worker to walk or work on it, and is laid so that the longitudinal direction thereof follows the building.

  The bracket 5 includes a horizontal member 7 extending in a substantially horizontal direction, a diagonal member 8 extending obliquely downward from the middle of the horizontal member 7, and a reinforcing member 9 connecting the horizontal member 7 and the diagonal member 8. The horizontal member 7 is made of a cylindrical hollow pipe member, and has a diameter of, for example, about 42.7 mm.

  Connecting members 11 are provided at both ends of the horizontal member 7. The connecting member 11 is for hooking the horizontal member 7 on the flange 4 of the support column 1, and the wedge 12 is inserted and fitted therein and supported.

  As shown in FIG. 4, the connecting member 11 has a substantially cylindrical shape and is formed in a substantially alligator shape on the end side, and spreads in the vertical direction toward the end side in a side view. The formed side opening 13 is formed. A space portion is formed inside the connecting member 11, and the side opening 13 communicates with the space portion. The connecting member 11 can sandwich the flange 4 from above and below by the side opening 13. An upper surface opening 14 extending from the vicinity of the end portion side to the horizontal member 7 side is formed on the upper surface of the connecting member 11. The connecting member 11 has a lower surface opening 15 formed on the lower surface thereof extending from the vicinity of the end portion to the horizontal member 7 side.

  The wedge 12 is formed in a vertically long substantially flat plate shape, and as shown in a circle in FIG. 2, a first protrusion 16 that protrudes both in the front direction and the depth direction is formed in the vicinity of the lower end portion of the wedge 12. . The wedge 12 is prevented from being pulled upward by the first protrusion 16 through the upper surface opening 14 of the connecting member 11.

  The wedge 12 has a second protrusion 17 formed at its upper end that is wider in the depth direction than the central portion of the main body. The wedge 12 is hooked by the second protrusion 17 at the periphery of the upper surface opening 14 of the connecting member 11 so that the entire wedge 12 does not enter the inside of the connecting member 11 through the upper surface opening 14.

  The connecting member 11 is formed with a protruding portion 18 for preventing the scaffold plate 3 from falling off (see FIGS. 4 and 5). The projecting portion 18 is a substantially columnar member formed in a substantially U shape, and extends so as to rise from the curved side surface of the connecting member 11. That is, the protruding portion 18 is formed so as to avoid the insertion fitting position of the wedge 12 inserted and fitted to the connecting member 11. Furthermore, the protrusion 18 is formed in the vicinity of the end of the connecting member 11. By providing the protrusion 18 as described above, the protrusion 18 protrudes from the uppermost surface of the horizontal member 7 by a predetermined length L (for example, about 30 mm) (see FIG. 5).

  In the bracket one side scaffold, the bracket 5 is used and the scaffold plate 6 is laid. More specifically, as shown in FIG. 3, the end portions of the two scaffold plates 6 are overlapped by a predetermined amount at the position where the bracket 5 is disposed. The end portions of the scaffold plate 6 are bound together with the connecting member 11 by, for example, a wire 19 or a rubber band shown in FIG. 3, whereby the scaffold plate 6 is fixed to the bracket 5.

  As described above, in the present embodiment, since the projecting portion 18 is formed on the connecting member 11 of the bracket 5, the scaffold plate 6 fixed to the bracket 5 with the number wire 19 or the like causes the cause of FIG. Even if the platform plate 6 moves in the direction indicated by the arrow S, the scaffold plate 6 is reliably brought into contact with the protruding portion 18. Therefore, the movement of the scaffold plate 6 is blocked by the protruding portion 18, and the scaffold plate 6 can be prevented from falling off from the bracket 5.

  Further, the protruding portion 18 is formed in a substantially U shape so as to avoid the insertion fitting position of the wedge 12, and the wedge 12 itself is not formed long as in the conventional configuration. Therefore, for example, the wedge 12 does not collide with other obstacles when the bracket 5 is transported and is not damaged or deformed. Further, it is not difficult to handle the bracket 5 when the bracket 5 is packed or when the bracket one-side scaffold is assembled or disassembled.

  Further, when assembling the one-side bracket of the bracket, a field worker drives the wedge 12 from above to bite into the retaining hole 4a of the flange 4, but the protruding portion 18 does not interfere with the driving of the wedge 12. . Furthermore, since the protrusion part 18 is formed in the end part vicinity of the connection member 11, when laying the scaffold board 6 on the bracket 5, the installation area | region of the scaffold board 6 can fully be ensured.

  The scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, the shape of the protruding portion 18 is not limited to the shape shown in the above-described embodiment as long as the scaffold plate 6 can be prevented from falling off. In addition, the shape, size, quantity, and the like of the bracket 5, the connecting member 11, the protruding portion 18, and the like in the above embodiment are not limited to the above embodiment, and can be appropriately changed in design.

  Moreover, the bracket 5 may be used not only for the bracket one-side scaffold shown in FIG. 1 but also for the one-side scaffold in which only one support column 1 is erected for each span. May be. Further, the scaffold plate 6 is not limited to the above-described embodiment. For example, a cloth frame with a floor in which hook members for hooking on the horizontal member 7 of the bracket 5 are formed at both ends may be applied. .
