Description

  The present invention relates to a baseboard for a temporary scaffold to be attached to a temporary scaffold constructed at a construction site or the like. More specifically, the invention can cope with a wide range of conditions of a pedestal and a flooring material in the temporary scaffold, and is lightweight. The present invention relates to a skirting board for temporary scaffolding that is not bulky and can be easily carried into and out of the site.

  Framework scaffolds and wedge-tight scaffolds known as temporary scaffolds to be built at the construction site form work floors with floor materials laid between arm timbers (horizontal materials) and perform various operations on this work floor. However, as a measure for preventing a crash from the temporary scaffold, it is instructed to install a baseboard so as not to create a gap between the floor material and the pedestal on the work floor of each floor.

  The I-type type (for example, refer to Patent Document 1) in which long plate-like baseboards, which are known as conventional baseboards for temporary scaffolding, are arranged in a standing state between the legposts of the temporary scaffolding, is a floor material and a pedestal. It is not enough to fill the gap between the vertical plate and horizontal plate, which is formed by bending a single metal plate, and both ends of the vertical plate are placed upright between the pedestals of the temporary scaffold with mounting brackets. An skirting board of an L-type integrated type (for example, Patent Documents 2 and 3) in which a gap between a floor material and a pedestal is closed by overlapping a horizontal plate on the floor material has been proposed.

  By the way, the L-type integrated temporary scaffolding skirting board is inexpensive in price, but has a problem that it is difficult to carry in and out of the building site because it is heavy and bulky.

  In order to solve the bulky problem of the L-type integrated type, the vertical plate and the horizontal plate can be divided, and the horizontal plate can be pivotally attached to the vertical plate so that it can be moved up and down. Although it is conceivable, the weight problem during carrying cannot be solved, and the adoption of the pivoting mechanism becomes structurally complicated, leading to an increase in cost.

  Therefore, the problem of the present invention is that the skirting board main body and the horizontal member are separated and independent, and the skirting board main body can be used independently, so that it can widely correspond to the conditions of the pedestal and flooring in the temporary scaffolding. In addition, it is possible to provide a temporary scaffolding baseboard which can be reduced in weight by separating the baseboard body and the horizontal member as a single body by separation and can be easily carried into and out of the site because it is not bulky.

  In order to solve the above-described problems, the present invention provides a baseboard body that is arranged in a standing state between the pedestals of the temporary scaffold using mounting brackets provided at both ends, and a separate member from the baseboard body. It consists of a combination of horizontal members arranged between a wooden body and a floor material laid on a temporary scaffold, and the horizontal member is attached to the baseboard body so as to be separable by a detachable fitting.

  The skirting board body is formed by providing a horizontal member receiving portion that bends toward a floor material side laid on a temporary scaffolding at a lower edge of a horizontally long vertical plate, and the horizontal member is a horizontally long horizontal plate. The upright plate that is bent upward is provided on the side edge of the side supported by the receiving portion, and the detachable fitting is provided on one of the opposing vertical plate and upright plate, and on the other side It can be formed by the provided pin insertion hole.

  The mounting bracket is fixed to the upper surface of both ends of the skirting board main body, hooks fitted from the floor material side to the pedestal of the temporary scaffold, vertical movement and horizontal rotation on the vertical board of the skirting board main body, It can be made to be formed by a rotating pin that is engaged with and disengaged from the surface opposite to the hook with respect to the pedestal of the temporary scaffold.

  Here, the skirting board body uses a metal plate having a length that fits between the pedestal spans of the temporary scaffolding, a receiving portion that is bent at a right angle to the lower edge of the vertical plate, and an upper edge in a direction opposite to the receiving portion. The horizontal member has a cross-sectional shape provided with a bent bending portion, and the horizontal member has a horizontal plate and an upright plate having the same length as the baseboard body, and a contact piece to the vertical plate at the upper end of the upright plate. The cross-sectional shape is bent.

  The retaining pin, which is a detachable metal fitting, uses a brace pin and is fixed horizontally at the center position in the length direction of the upright plate in the horizontal member so as to protrude in the opposite direction to the horizontal plate. A pin insertion hole is provided at a central position in the vertical direction, and the horizontal member can be attached to and detached from the skirting board main body by inserting and removing the retaining pin with respect to the pin insertion hole.

  The hook of the mounting bracket is fixed in a horizontal state to the upper end of the mounting plate that is vertically long, and the mounting plate is fixed to the vertical plate of the baseboard body by overlapping the surface on the receiving portion side at the end, Arranged on the upper surface of the end of the skirting board main body, and by making the height position of the hook different at the end of the skirting board main body, when the skirting board main body is mounted side by side, interference of hooks adjacent to the end part is prevented. I try to escape.

  In addition, the rotary pin is formed by using a circular shaft material, and is formed by bending a horizontal locking shaft at a right angle at the upper end of the vertical shaft, and is fixed to the surface opposite to the hook with respect to the vertical plate of the baseboard body. It is held so that it can be rotated and moved up and down with a support metal.

  This support hardware is provided with a folding plate on the upper and lower sides of the base plate fixed to the vertical plate of the baseboard body and a locking plate in the middle, and from a notch provided in the upper folding plate to a hole provided in the locking plate and the lower folding plate. By inserting the circular shaft material of the rotation pin, the rotation pin is held in the lowered position by receiving the engagement shaft by the engagement plate, and this rotation pin can move up and down between the upper bent plate and the engagement plate, The rotation of the rotation pin is restricted by the engagement piece and the engagement shaft standing on the tip of the engagement plate. By operating the rotation and rotation of the rotation pin, the engagement shaft can be used as a pedestal of the temporary scaffold. On the other hand, it is possible to select a state where it is locked to the surface opposite to the hook and a state where it is separated from the pedestal.

  According to the present invention, since the skirting board main body and the horizontal member are separate members, the skirting board main body and the horizontal member can be separated into a single unit to reduce the weight, and since it is not bulky, it can be easily carried into and out of the site.

  Also, if the distance between the pedestal and flooring in the temporary scaffolding is narrow, the horizontal member may be unnecessary. In this case, it is possible to use the baseboard body alone, and the conditions of the pedestal and flooring in the temporary scaffolding Therefore, it is possible to reduce the total cost of the skirting board by making it possible to use the skirting board body independently.

  Furthermore, by using a retaining pin insertion method for coupling the skirting board main body and the horizontal member, the skirting board main body and the horizontal member can be easily attached and detached on site.
