Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a foldable and height-adjustable interior temporary scaffold used for interior construction work and the like.

[0002]

[Prior art]

 Conventionally, there have been various scaffolds that can be adjusted in height and can be folded in the scaffolding used for interior work and the like. One of them was to set a pair of L-shaped flat plates so that two hinged work floors could stand up back-to-back without protruding a part of the hinge on the upper surface of the turned work floor. There was a temporary scaffolding for interiors (see Jpn. Pat. Appln. KOKAI No. 4-50354) in which two pairs of special hinges were used to fold the work floor.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional temporary scaffolding for interiors, the beam member of the frame assembly main body on which the special hinge for combining the L-shaped flat plates in pairs is pivotally supported is attached to the upper part of the frame assembly body. However, there was a problem that when the work floor stood up, it did not stay in a position lower than that, and when it was folded, the overall height became high.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention uses a framing main body with four telescopic columns composed of double pipes, with a depth shorter than the width of the work floor and two work floors each being folded. Arrange them in a rectangle with a horizontal width that can be inserted while being folded, and connect the outer tubes of these telescopic columns to the beams at a height that is less than half of these tubes and in the horizontal direction, and in each direction in the depth direction. The two work floors are connected to each other and stand up back to back at the position of the beam member of the frame main body and the center of the horizontal width of the frame main body when not needed. In order to place the hinges adjacent to each other, two sets of hinges of I-shape and L-shape are used to pivotally connect the frame body and the work floor, respectively. In this way, the overall height when the work floor is erected and folded can be made lower than before, and the handling efficiency can be improved.
