Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a scaffold to be used as an alternative in the stage of building a house, before the stage of making scaffolds from logs.

(Prior Art) Conventionally, scaffolds have been used to expand the work space in the construction of houses and the like.

The simple scaffold currently used is composed of a holding part provided with a means for holding a pillar of a house, and a flat plate part attached to the side of the holding part. Then, the pillars are sandwiched and fixed by the sandwiching portion, the flat plate portion is laterally extended, and the plate is bridged over the flat plate portion to form a scaffold.

(Problems to be solved by the invention) However, the above-mentioned scaffold was held because the middle part of the pillar was pinched and fixed by the holding means, and the weight of the worker was applied to the flat plate portion that horizontally extended from there. An excessive load was applied to the part, and the pillar was sometimes curved and damaged. As a result, it may have adverse effects on the attachment of joints and braces in the case of a hut structure, and further, the sway of the scaffolding is large and the safety is low.

(Means for Solving the Problems) In order to solve the above problems, a household scaffold of the present invention has a base part having a U-shaped vertical cross section with a fastening screw on one side plate, and an upper part of the base part. A lower support column that is erected on the upper part and has a locking hole formed in the upper part, and a plurality of locking holes that are formed in a smaller diameter than the lower support column in the lower part in the longitudinal direction, and a horizontal body is attached to the upper end of the horizontal structure. It consists of an upper strut on which a supporting member for the scaffolding plate is horizontally mounted, and a pin is inserted through the locking hole of the upper strut and the locking hole of the lower strut so that the upper strut can move up and down. It is fixed to.

(Operation) The foundation is fixed to the base of the building, and the lower pillar is erected on the upper surface. Then, the upper support is fixed to the upper end of the lower support at an arbitrary height. The support member is extended from the horizontal body attached to the upper end of the upper support, and the scaffold plate is placed on the support member.

(Example) An example of the present invention will be described. FIG. 1 is a front view, FIG. 2 is a plan view, and FIG. 3 is a plan view showing a usage state.

The scaffolding of this embodiment is based on a base 10 that is fixed to the base 60 of the building.
A columnar lower pillar 20 and an upper pillar 30 which are erected on the foundation portion 10, a horizontal body 33 and a supporting member at the tip of the upper pillar 30.
It consists of 34 and.

Explaining this structure in detail, the base 60 is fixed by anchor bolts on a foundation 61 made of concrete. The base portion 10 is composed of an upper plate 11 and a pair of side plates 12 and 12, and has a vertical cross section of a U-shape. A square screw 13 is screwed into one of the side plates 12, and the ratchet 13 at the end of the square screw 13
The handle 14 is fixed via a. Further, a pressing plate 15 is formed on the opposite side of the square screw 13, and the handle 14 is operated so that the pressing plate 15 and one side plate 12 hold and support the base 61. The square screw 13 and the side plate
You may hold the base 61 with 12.

The lower support column 20 is erected by welding on the upper plate 11 through four reinforcing members 17, and has a locking hole 23 in the upper portion.
In addition, the lower support column 20 is pipe-shaped and has an upper support column 30 inside.
Can be inserted.

The upper strut 30 has a smaller diameter than the lower strut 20, and a plurality of locking holes 31 having the same diameter as the locking hole 23 are formed in the upper part at regular intervals in the vertical direction. Then, the upper support column 30 is fixed to the upper part of the lower support column 20 by penetrating the locking hole 23 of the lower support column 20 and the locking hole 31 of the upper support column 30 with the pin 21. Further, when the pin 21 is placed on the upper end of the lower support column 20 with the pin 21 penetrating only the upper support column 30, the upper support column 30 can rotate in the horizontal direction at the upper end of the lower support column 20.

The horizontal body 33 is welded to the upper end of the upper column 30. In this embodiment, the size is 40 mm in width and 80 mm in height, and the support member 34 is slidably fitted therein. The support member 34 has a width of 30 mm and a height of 70 mm, and has a structure resistant to a bending moment in the vertical direction. The size is not limited to this and can be arbitrarily determined.

Next, the operation of this embodiment will be described. A plurality of the scaffolds of this embodiment are installed in parallel on the base 60 at regular intervals for use (see FIG. 3).

The scaffold is installed by covering the base 60 of the house with the base 10 and rotating the handle 14, and pressing and fixing the pressing plate 15 at the end of the square screw 13 to the base 60. This fixing is quick because the screw is a square screw 13 and is via a ratchet.

Next, place the upper strut 30 on top of the lower strut 20 and
Align 31 with locking hole 23 and penetrate pin 21 to
Secure the upper column 30 to the upper end of the. Then, the support member 34 is horizontally extended from the horizontal body 33 at the tip of the upper support column 30 by an appropriate length, and the scaffold plate 40 is placed on the support member 34.
Various work is performed on this board.

As described above, according to the present embodiment, since the foundation 10 is fixed to the base 60, stability is good and safety as a scaffold is high. It is small and lightweight, and can be installed and removed easily and quickly by operating the handle 14, thus improving work efficiency. Also, the upper column 30
Can be stored inside the lower column 20 and is highly portable.

This embodiment can be installed not only on the base 60 on the ground but also on the roof portion of the building as shown in FIG. In this case, the crane 50 may be attached to one end of the support member 34 and the scaffold plate 40 may be placed on the other end of the support member 34. Accordingly, hoisting of materials and tools can be performed easily and quickly, and the hoisted materials and the like can be placed on the scaffolding plate 40.

In addition to the above-described configuration, the present invention may be configured such that a fluid pressure cylinder is provided in the lower column 20 and the upper column 30 is moved up and down by fluid pressure. Further, the support member 34 may also be configured to be movable back and forth by a fluid pressure cylinder. Further, a plurality of locking holes 23 on the outer peripheral surface of the lower column 20 may be formed at every 90 degrees. Further, a turning means for the upper strut 30 may be provided between the lower strut 20 and the upper strut 30 so that the upper strut 30 can be swung in the horizontal direction.

(Advantages of the Invention) Since the present invention has the above-described configuration, since the foundation is directly fixed to the base for use, the pillar is not curved or damaged. In addition, the portability is good because the upper column can be stored inside the lower column. Moreover, it is safe as a scaffold because the scaffolding is stable and the stability is high. For this reason, it is possible to accurately and surely attach the joints and braces when the roof is assembled. further,
It has an effect that it can be used for multiple purposes in addition to scaffolding, such as placing materials.
