Description

  The present invention relates to a scaffolding baseboard suitable for a scaffold used at a civil engineering construction site, a construction site, or the like.

  In civil engineering construction sites, construction sites, etc., work scaffolds such as those shown in FIG. Specifically, the scaffold 51 is formed by a support column 52 extending in the vertical direction and a cloth material 53 provided perpendicularly to the support column 52 and in the horizontal direction. A scaffold plate 54 is installed between the facing fabric materials 53.

  In order to prevent the fall of an object such as a tool placed on the scaffolding plate 54 or the operator's stepping off of the foot, the width for the scaffolding that stands up in the vertical direction (Z direction) on the outer edge of the scaffolding plate 54 A tree (hereinafter, simply referred to as “baseboard”) is installed.

  The skirting board has a plate-like member (baseboard body) having a length in the longitudinal direction (Y direction) substantially equal to the distance between the adjacent support columns 52, and is constructed between the support columns 52. Fixing members such as metal fittings are attached in the vicinity of both ends in the longitudinal direction of the skirting board main body, and the skirting boards are attached to the columns 52 by this fixing member.

  The fixing member includes a type that can be attached to and detached from the baseboard body and a type that is integrated with the baseboard body. If the fixing member is detachable from the skirting board main body, the management cost of the fixing member is extra, and if the fixing member corresponding to the desired skirting board main body (removable) is not prepared in the field, the skirting board is attached. It may not be possible, and sudden construction of the scaffold may be difficult. From these viewpoints, it is preferable to use a type of baseboard in which the fixing member is integrated with the baseboard body.

  Patent document 1 is mentioned as literature which disclosed the invention which attaches a baseboard main body to a support | pillar via a fixing member.

JP-A-11-141116

  It is necessary for the fixing member to protrude from the plate surface of the skirting board body so that the column can be gripped. In the prior art including the above-mentioned Patent Document 1, by integrating the skirting board main body and the fixing member, the fixing member always protrudes from the plate surface of the skirting board main body. Various problems are caused from time to time. Specifically, when the skirting boards are stacked and stored, there is a problem that the protruding fixing member becomes bulky. In addition, there is a risk of causing an accident or injury by contacting the protruding fixing member during transportation of the skirting board. Thus, conventionally, the baseboard in which the fixing member is integrated has a problem that the operability is poor.

  Further, in the skirting board disclosed in Patent Document 1, a connecting portion (reference numeral 92 in FIG. 1 of Patent Document 1) is provided at an end portion in the longitudinal direction (Y direction) of the skirting board. When the baseboards are mounted side by side in the horizontal direction (Y direction), both one baseboard and the other baseboard are supported by one cloth material (lateral beam). Specifically, a description will be given with reference to FIG. 4A schematically showing FIG. The connecting portion 92a provided at the end of one baseboard and the connecting portion 92b provided at the end of the other baseboard are supported on the cloth material 53, respectively. In the invention disclosed in Patent Document 1, when a plurality of baseboards are arranged in the Y direction, as shown in the range A in FIG. 4A, the Y direction end faces of the lower portions of the connection portions 92a and 92b are connected to each other. Will match. Thus, in the state which faced the Y direction end faces of the lower part of the connection part (or baseboard main body) arranged in the Y direction, the length of the connection part (or baseboard main body) supported by the cloth material 53 is long. There is a problem that the skirting board is likely to slide down due to short vibrations or the like.

  The present invention has been completed in view of the above-mentioned problems, prevents the fixing member from being bulky during transportation and storage, improves the operability, and the cloth material at the end in the longitudinal direction. It is an object of the present invention to provide a skirting board that sufficiently secures a length near the contact portion and is difficult to slide down when subjected to vibration or the like.

FIG. 3 is an explanatory diagram of a skirting board according to the present invention. FIG. 4 is an explanatory diagram of the ends of the baseboards arranged in the Y direction. FIG. 5 is an explanatory view showing a hanger member used in the present invention. FIG. 6 is a cross-sectional view showing a positional relationship in the X direction between adjacent positioning portions.

  First, with reference to FIG. 2, a work scaffold (sometimes simply referred to as “scaffold”) and a scaffolding baseboard (sometimes simply referred to as “baseboard”) will be briefly described. In the following description, the axial direction of the cloth material 53 is the X direction, the longitudinal direction of the scaffolding board 54 and the baseboard body 11a is the Y direction, and the axial direction of the support column 52 is the Z direction.

  First, a work scaffold is formed by assembling a skeleton with the support columns 52 extending in the vertical direction and the cloth material 53 extending in the horizontal direction, and constructing a scaffold plate 54 between the cloth materials 53. In addition, a baseboard 11 is provided on the outer edge of the scaffold board 54 in order to prevent the falling of objects and people.

  The skirting board 11 has a skirting board main body 11a that rises in the Z direction along the outer edge of the scaffold board 54. The skirting board main body 11 a is a long plate-like member whose length in the longitudinal direction (Y direction) is equal to or greater than the distance between the adjacent struts 52 so as to be spanned between the adjacent struts 52. A fixing member (provided on the back side of the paper surface in FIG. 2 and not shown) is attached to one side of the skirting board main body 11a. Although details will be described later, in addition to the baseboard body 11a and the fixing member, the baseboard 11 may include a shielding plate 11c in the lower portion and may include a flange portion 11d in the upper portion. The positioning part 11e is provided in the longitudinal direction (Y direction) edge part of the lower part of the baseboard main body 11a. A gap may be opened between the shielding plate 11c and the scaffold plate 54.

  When attaching the skirting board 11, after attaching the fixing member to the support column 52, the skirting board main body 11a is lowered and the positioning portion 11e in the lower part of the skirting board main body 11a is brought into contact with the cloth material 53. The lower part of the skirting board 11 is fixed. A wedge head 55 that protrudes upward from the upper surface of the cloth material 53 may be provided in the vicinity of the intersection between the cloth material 53 and the support column 52. In this case, the positioning portion 11e is positioned between the wedge head 55 and the support column 52. Although not shown in the drawings, a wedge tail portion (lower portion) that protrudes downward from the lower surface of the fabric material 53 is inserted into a socket portion that protrudes to the side of the support column 52, whereby the fabric material 53 is inserted into the support column 52. Can be attached to.

  Next, the skirting board of the present invention will be described in more detail with reference to FIG. FIG. 3A is a plan view of a skirting board according to the present invention, FIG. 3B is a front view of the skirting board according to the present invention, and FIG. 3C is a right side of the skirting board according to the present invention. FIG.

  As shown in FIG.3 (c), the fixing member 11b is attached to the surface (right surface in a figure) facing the support | pillar of the baseboard main body 11a. The fixing member 11b is attached so as to be foldable. The solid line in the figure shows a state in which the fixing member 11b is projected in order to attach the skirting board to the column, and the dotted line in the figure shows the state in which the fixing member 11b is folded during storage or transportation of the skirting board. It is a state. The mode in which the protruding state and the folded state of the fixing member 11b can be changed without removing the fixing member 11b is not particularly limited. For example, the fixing member 11b may be attached to the skirting board main body 11a via a hinge. In addition, it is preferable that the fixing member 11b can hold | maintain the state protruded horizontally.

  The fixing member 11b is desirably folded when the baseboard 11 is stored. When the skirting board 11 is stored, a plurality of skirting boards 11 are stored in an overlapping manner, but by fixing the fixing member 11b, the fixing member 11b is prevented from being bulky, Less storage space for skirting boards 11 is required.

  Further, it is desirable to fold the fixing member 11b when the skirting board 11 is transported. Thereby, danger, such as an accident and an injury by contacting with the fixing member 11b which protruded from the plate surface, can be prevented.

  From the above viewpoint, it is desirable that the fixing member 11b is folded during storage and transportation, and the fixing member 11b is protruded immediately before being attached to the column 52, and then the base plate 11 is attached.

  The fixing member 11b is not particularly limited as long as the fixing member 11b can be fixed to the column. For example, a spring-type fixing bracket that has a substantially Ω cross section and can hold the column by an elastic force such as a spring can be suitably used.

  The skirting board main body 11a preferably includes a notch at the other end having the same height as the fixing member 11b at one end in the longitudinal direction (Y direction). The height of the fixing member 11b refers to the height at which the protruding tip of the fixing member 11b is located when the fixing member 11b is in the protruding state. In the example of FIG. 3B, notches are provided in the lower right end and the upper left end of the skirting board main body 11a, and the fixing member 11b is attached to the lower left end and the upper right end having the same height. It is done. With such an arrangement, when a plurality of baseboards 11 are mounted side by side in the horizontal direction (Y direction), the baseboard body 11a of one baseboard 11 becomes an obstacle, and the other baseboard 11 This prevents the fixing member 11b from being attached to the support column 52. In addition, the notch part of a right lower end part is provided with the positioning part 11f separate from the baseboard main body 11a so that it may mention later.

  In the example of FIG. 3B, either the upper end or the lower end is notched at both ends of the baseboard body 11a, but the notch may be other than the upper end and the lower end. .

  It is preferable to provide the shielding board 11c in the lower part of the baseboard main body 11a. As shown in FIG.3 (c), the shielding board 11c is provided so that it may become substantially right angle with the baseboard main body 11a, and it protrudes on the opposite side to the direction where the fixing member 11b protrudes. The shielding plate 11c has a function of filling a gap generated between the skirting board main body 11a and the scaffolding plate 54 and preventing falling of an object or the like through the gap. In addition, the width | variety, length, etc. of the shielding board 11c can be suitably changed according to the specification etc. of a scaffold.

  As shown to Fig.3 (a), the flange part 11d which is thick and protrudes in the axial direction (X direction) of a cloth material can be provided in the upper part of the base board main body 11a. A so-called “haze” is formed in the flange portion 11d by bending the upper portion of the baseboard body 11a. By providing the flange part 11d, the load resistance from the upper part of the base board 11 can be improved. In the example of FIG. 3C, the flange portion 11d at the upper portion of the skirting board main body 11a protrudes on the front side in the X direction (side on which the shielding plate 11c extends), but on the back side (fixing member 11b). May protrude to both the front side and the back side.

  In addition, as shown in FIG. 3B, positioning portions 11e and 11f are provided below the both ends of the base plate body 11a in the Y direction. The positioning portions 11e and 11f abut on the upper portion of the cloth material 53 in order to prevent the baseboard 11 from sliding down after the baseboard 11 is attached to the support column 52 by the fixing member 11b. In the example of FIG. 3B, the left end of the baseboard body 11a has a shape in which the upper side of the baseboard body is cut out, and the baseboard body 11a remaining on the lower side of the cutout part is the positioning portion. 11e. On the other hand, the right end of the baseboard body 11a in FIG. 3 (b) has a shape in which the lower side is cut out, and a thin plate provided so as to protrude laterally at the cutout. A shaped hanger member becomes the positioning portion 11f. In the example of FIG. 3B, the hanger member is separated from the skirting board main body 11a, and the skirting board main body 11a and the hanger member are joined by screwing, but by other joining methods such as welding. You may join. Moreover, the positioning part of the shape similar to the hanger member shown in FIG.3 (b) can also be formed by a part of base board main body 11a.

  As shown in FIG. 4B, the positioning portions 11 e and 11 f preferably have a length in the longitudinal direction (Y direction) of each baseboard body 11 a equal to or larger than the outer diameter of the cloth material 53. When the length is less than the outer diameter, as shown in FIG. 4A, which is a conventional example, the length of the end of the baseboard in the vicinity of the contact portion with the cloth material cannot be provided sufficiently, and vibration or the like. There is a risk that the skirting board 11 slides downward. In the present application, by setting the length to be equal to or greater than the outer diameter, both ends of the left and right baseboards can be provided so as to cross the cloth material, and when vibration or a load from above is applied. However, it is possible to reliably prevent the skirting board from sliding down. In addition, the length of the positioning parts 11e and 11f in the longitudinal direction refers to a length protruding from the end surface in the Y direction of the notch part of the baseboard body 11a. The outer diameter of the cloth material 53 may be a circle diameter if the cloth material 53 has a circular cross section as shown in FIG. 4B. The length in the Y direction may be adopted.

  It is preferable that the positioning portion 11e and the positioning portion 11f at the both ends of the skirting board main body 11a have different positions in the X direction. 3A is a simplified drawing, the position of the positioning portion 11e and the position of the positioning portion 11f are not drawn differently.

  First, it demonstrates using FIG. In FIG. 5, the hanger member 31 which forms the positioning part 11f attached to the baseboard main body 11a is shown. 5A is a front view, and FIG. 5B is a plan view.

  As shown to Fig.5 (a), the fixing | fixed part 31a provided with the hole 32 for attaching to the base board main body 11a is provided in the left side of the hanger member 31. As shown in FIG. Further, as shown in FIG. 5B, a bent portion 31b is formed adjacent to the fixed portion 31a, and then a contact portion 31c that actually contacts the cloth material is formed. By providing the bent part 31b extending in the Y direction while changing the X direction position, the X direction position of the contact part 31c and the X direction position of the baseboard body attached to the fixed part 31a are different.

  Next, a description will be given with reference to FIG. In FIG. 6, the X direction position of the positioning part 11e of one base board 11 arranged in the Y direction and the positioning part 11f of the other base board 11 is shown by a sectional view. The positioning part 11e provided on one baseboard body is shown on the left side of the figure, and the positioning part 11f provided on the other baseboard body is shown on the right side of the figure.

  As shown in FIG. 6, if the positions of the two positioning portions in the X direction are different, even when two baseboards are installed side by side in the Y direction, the positioning portion of one baseboard and the other baseboard Can be prevented from interfering with the positioning portion. In particular, when the length of the positioning portions 11e and 11f is equal to or larger than the outer diameter of the cloth material 53 as shown in FIG. 4B, a position where both positioning portions overlap in the Y direction is generated. Since the positions of the portions 11e and 11f in the X direction are different, it is possible to prevent the positioning member of one baseboard from becoming an obstacle and the other baseboard from being attached.
