Description

  The present invention relates to a gap closing shielding plate suitable for closing gaps between a plurality of adjacent scaffold plates in a framework scaffold.

  As this type of conventional framework scaffold, for example, the one shown in Patent Document 1 has been developed.

As shown in FIG. 14, this framework scaffold is composed of a frame 3 made up of building frames 1, 1 that are continuously inserted in the vertical direction, and a horizontal frame 2 that is installed between the building frames 1, 1. Then, after arranging a large number of the frame bodies 3, the scaffolding plates 4, 4 are constructed on the horizontal member 2 via hooks, and the baseboards 5, 5 are arranged on both sides of each scaffolding plate 4, 4. The baseboards 5 and 5 are connected to the building frames 1 and 1 which also serve as an upper handrail by a wire or the like.
Japanese Utility Model Publication No. 4-129256 (see drawing)

  The above-mentioned conventional scaffold using the scaffold board has the following problems.

  The scaffolding plates 4 and 4 are continuously arranged in the longitudinal direction. In this case, the scaffolding plates 4 and 4 are provided by hooking the horizontal members 2 with hooks extending from both front and rear ends. A gap corresponding to the width of the two hooks is formed between the scaffold plates 4 and 4 adjacent to each other in the front and rear, and there is a risk that a tool or the like on the scaffold plate falls downward from the gap.

    Therefore, an object of the present invention is to provide a gap closing shielding plate that prevents a gap from being generated between adjacent scaffold plates when a plurality of scaffold plates are connected in the front-rear direction in a framework scaffold. .

  In order to achieve the above object, one means of the present invention includes a plate body, a mounting portion formed in the longitudinal direction along the plate body at a lower portion of the plate body, and a drilling in the plate body along the short direction. And a long groove that is notched in the mounting portion and faces the long hole.

  Similarly, the other means includes a plate body, a mounting portion coupled to the lower portion of the plate body via a stopper, and a hook insertion long hole formed in the plate body along the short direction. The body is composed of a horizontal plate portion and inclined portions provided at both ends of the plate portion, and the attachment portion is formed of a spring plate having a holding portion bent on both sides.

  The present invention has the following effects.

  According to the invention of each claim, when the shielding plate is installed between the scaffolding plates in the framework scaffolding, the gap between the scaffolding plates is closed by the shielding plate, which is safe.

  Similarly, since the shielding plate can be coupled to the horizontal member via the mounting portion, the plate body is prevented from being lifted or moved.

  In addition, since the shield plate has a long hole for hook insertion, even if the plate is placed on the hook, the upper part of the hook fits into the long hole, and the hook and the plate of the shield plate interfere with each other. Without positioning, the plate can also be positioned.

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

  1 to 5 show an embodiment of a framework scaffold using a shielding plate according to the present invention.

    As shown in FIG. 3, the long hole 8b and the long groove 12a are for inserting the bent upper portions of the hooks 9 and 9, and one or a plurality of the long holes 8b and the long grooves 12a are formed according to the number of hooks.

    The length of the shielding plate 8 is arbitrary, and is selected according to the width of the scaffold plate 6 and the length when arranged in the horizontal direction.

    It is preferable to form a taper 8c downward on the upper surfaces of both ends of the plate body 8a.

    The attachment portion 12 corresponds to the outer surface shape of the horizontal member 2, and is formed with a fitting groove 12b having a C-shaped cross section, for example, and the fitting groove 12b is fitted to the horizontal member 2.

    As shown in another embodiment of FIG. 5, the shielding plate 8 includes a plate body 8d, a mounting portion 14 coupled to a lower portion of the plate body 8d via a stopper 13 such as a pin, and a short side to the plate body 8d. You may comprise with the long hole 8b for hook insertion drilled along the direction.

    The plate body 8d includes a horizontal plate portion 8e and inclined portions 8f and 8f provided at both ends of the plate portion 8e, and the attachment portion 14 includes a spring plate provided with holding portions 14a and 14a bent on both sides. ing.

    In this case, after the shielding plate 8 is installed between the scaffolding plates 6 and 6, the holding portions 14a and 14a are fitted to the horizontal member 2, and the upper portion of the hook 9 is inserted into the long hole 8b.

    The skirting board 7 is formed in a cross-section L shape with a skirting board main body 15 standing upward and a support plate 16 provided horizontally at the lower part of the skirting board main body 15, and is attached to the building frame 1 at the end of the baseboard main body 15. An attachment member 7 that is detachably fitted is provided.

    As shown in FIG. 4, the baseboard body 15 has a side L-shaped cutout portion 15 a formed in the lower portion on the front side, which is one end, and a side L-shaped cutout portion 15 b formed in the upper portion on the rear side, which is also the other end. Yes.

    A mounting member 7 is coupled to outer side surfaces of both ends of the baseboard body 15 via a stopper 17a such as a pin. The mounting member 7 is, for example, a spring plate 17b having a C-shaped cross section as shown in the embodiment of FIG. It consists of

    The baseboard body 15 is attached to the building frame 1 via a spring plate 17b, and the support plate 16 is disposed so as to overlap the upper surface of the plate body 10 constituting the scaffold plate 6, whereby the scaffold plate 6 and the baseboard 7 There is no gap between them.

    When the baseboard 7 is continuously attached in the longitudinal direction along the scaffold plate 6, the notch 15b of the front baseboard body 15 and the notch 15a of the back base body 15 are fitted to each other, A gap is not generated between adjacent baseboard bodies 15 and 15.

    As shown in FIGS. 1 to 4, the scaffold device A according to the present invention has a large number of frames 3 arranged in a row, and a scaffold plate is interposed between the horizontal members 3 and 3 of each frame 3 via hooks 9 and 9. A number 6 and 6 are arranged in series along the longitudinal direction.

    In this case, a shielding plate 8 is installed from above in order to close the gap P between the scaffolding plates 6 and 6, the fitting groove 12c of the mounting portion 12 is fitted to the horizontal member, and the hooks 9 and 9 are fitted. Is fitted into the long groove 12a and the long hole 8b.

    Next, the support piece 16 of the baseboard 7 is piled on each scaffold board 6, the L-shaped spring board 15a which is the attaching part 17 is fitted to the building frame 1, and the baseboard 7 is attached to the left and right sides of each scaffold board 6. It is made to stand continuously to prevent a gap from being generated between the scaffolding plate 6 and the scaffolding plate 6.

    The baseboard bodies 15 adjacent to each other in the front-rear direction are continuous in the longitudinal direction while being fitted through the notches 15a and 15a at the ends so that no gap is generated between the baseboard bodies 15 and 15.

    As shown in another embodiment of FIG. 6, the attachment member 17 provided on the baseboard 7 is constituted by a known clamp 18 coupled to the outer surface of the end portion of the baseboard body 15 via a stopper 17a. Also good.
