Description

Description: TECHNICAL FIELD The present invention relates to a scaffolding for temporary use used in interior work of a building, and in particular, small transportation of upper and lower floors can be performed using a small lift, and a narrow passage. It is possible to carry around, scaffolding is widely installed in the room, and the interior work such as the ceiling surface can be done on it.
Also, when the scaffold is not used, the wide scaffold floor and the legs are folded to reduce the protruding portion, and the present invention relates to an internal scaffold for construction which is easy to handle and transport.

(Prior art) When performing work in high places such as the ceiling in the interior work of a building, it is necessary to build a temporary scaffold.

When this temporary scaffold is assembled indoors, a large entrance cannot be transported due to a narrow entrance or corridor. Therefore, a pair of stepladders have been conventionally known, as disclosed in Japanese Utility Model Publication No. 62-126438. Were set apart from each other, and square steel pipe scaffolding boards were hung between the stepladders as temporary scaffolds.

(Problems to be Solved by the Invention) However, in this conventional one, there is a gap in the layout of the scaffolding plates, which is a problem in terms of regulations, and there is a risk that it may be unfavorable for safety management and may fall off the foot and fall.

In addition, since the scaffolding boards are arranged in a simple manner, when an operator walks on the scaffolding board, the scaffolding board splashes and the item placed on the scaffolding board falls, and other work on the scaffolding board There was a problem in that the work was disturbed by transmitting vibrations to the workers.

In addition, when moving a heavy and long stepladder, square steel pipe, and scaffolding plate, there was a problem of hitting other members, wall surfaces, and floors and scratching.

(Means for Solving Problems) The present invention has been made to solve such conventional problems, and small transportation on the upper and lower floors can be performed by a permanent elevator, or curved stairs and narrow corridors and entrances can be installed. You can pass freely and form temporary floors in various rooms on the upper and lower floors, and you can move freely without damaging the floor with casters, safely on the temporary floor adjusted to any height Providing internal scaffolds for use in the interior construction work of workable buildings.

The gist of the present invention is to dispose a pair of panels, whose surfaces are non-slip, at the same height in a butting state, and to rotate extendable legs before and after the end of the panel opposite to the butting end. Between the insertion parts of the left and right legs so that both panels can be crotch, and the legs are freely movably attached and are provided at the four corners below the mating ends of the panels The horizontal rod that is laid horizontally on the side, the connecting member that is laid between the insertion parts of the front and rear legs, and the horizontal rod and the butt end of each panel are connected by inner links and outer links, and Make the distance between the link connecting pins of the link longer than the distance between the link connecting pins of the inner link, and
An unequal leg trapezoidal link mechanism is formed between each set of links and the horizontal rod, and the lower part of the leg attached to the panel end opposite to the butt end of the panel is connected with the connecting member by a rod. Then, attach casters to the lower end of each leg,
A lock for height adjustment that adjusts the length of the extendable leg is provided on each leg, and when each panel is rotated from the horizontal state to the vertical state by the above-mentioned unequal leg trapezoidal link mechanism, an appropriate interval is provided between each panel. The internal scaffolding for construction is characterized in that the legs of the end opposite to the butt end of the panel are turned to the back side of the panel with a rod to reduce the lateral projection. .

(Operation) In the building internal scaffolding of the present invention, each panel is rotated by the unequal leg trapezoidal link mechanism, and the scaffolding floor surface is bent in the middle,
The panels are stored and transported in a vertical position.

After being transported to the construction site, it is loaded into the room for interior work using casters, and the panels are spread left and right by the unequal leg trapezoidal link mechanism in the room for construction. When the panel is pushed to the left and right, the leg attached to the end opposite to the butt end of the panel has the lower leg connected to the connecting member by a rod, so that the rod will move as the panel rotates. When the legs are rotated and the panel becomes horizontal, each leg becomes vertical and grounds on the floor to support the panel horizontally. After that, the length of each leg is expanded and contracted to adjust the height of the panel, and then locked after adjusting.

In this way, a large number of internal scaffolds are assembled in the room, and the scaffold floor surface is expanded one after another.

The worker uses the upper surface of the panel, which is higher than the floor surface of the building, as the scaffolding floor surface, and works the ceiling surface on the non-slip scaffolding floor surface occupying a large area in the room. Workers can concentrate their nerves only on the ceiling surface without paying attention to their feet, and since they do not have to step down the scaffold and move heavy objects such as a stepladder at the end of each narrow area, it is safe and finishes in a short time. Can do good job.

In addition, even if a heavy material is placed on the scaffolding floor, the casters can move smoothly without scratching the floor, so a wide range of work can be performed even if the number of internal scaffolds is small, and additional -Can be used alone for repair work.

After finishing the work, unlock the legs to minimize the length of the legs, lower the panel to the lowest position, and then lift the end opposite the butt end of the panel to put it in the folded state.
In this folded state, the abutting contact between the panel and the horizontal rod prevents further rotation of the panel, and the vertical state is maintained. Moreover, since the panels do not contact each other in the vertical state at the same time, the panels can be prevented from being pushed down in the horizontal direction due to the contact between the panels, and stable transportation can be performed.
Also, since the leg portion provided at the end opposite to the butt end of the panel is connected to the connecting member by the rod, the leg portion rotates so as to be pulled to the back side of the panel as the panel rotates, and The scaffold is folded in a short width to facilitate transportation and storage.

After folding, the casters need to be carried out one after another from the room using casters, and the number of members need only be checked individually.

Due to the construction method using this internal scaffold, the work efficiency can be significantly improved compared to the conventional one.

(Example) Hereinafter, the Example of this invention is described based on drawing.

In the embodiment shown in the figure, a pair of panels (1), (1) having a length of 1.5 m and a width of about 1 m are arranged in a butting state at the same height to form a scaffolding floor surface (2). Punching metal, expanded metal, or the like is attached to the upper surface of the panel (1) as a slip stopper. Further, an extendable leg portion (5) is rotatably attached to a corner portion of an end portion of the panel (1) opposite to the butt end.

Included casters (8). Each leg (5) is provided with a lock (9) for fixing the length of the leg to a required length. The lock (9) is urged toward the fixed side by the spring (12), and when released, the pin (13) is pulled out from the groove (14) and fixed to the end surface of the guide tube (15). The leg portion (5) is provided with three lock holes (16) into which the lock (9) is inserted, so that the length of the leg portion (5) can be adjusted in three stages.

The horizontal state of the panel (1) is supported and restrained by the floor (1) of the panel (1), the grounded leg (5) and the link (11), and is stably held.
The two panels (1) form a horizontal scaffolding floor (2).

When folding the panel (1), lift the end (7) opposite to the butt end of the panel (1), and the panel (1) will rotate around the link (11) part of the butt end and be in a vertical state. Becomes Further rotation of the panel (1) is limited by the butt end of the panel (1) descending with the rotation and contacting the horizontal rod (4), and the panel (1) is held vertically. . Moreover, the panel (1)
The butt edges of the panels (1) move in a direction away from the butt edges as the panels (1) stand up, and an appropriate gap is generated between the vertically erected panels (1). By providing an appropriate gap between the panels (1), the panels (1) do not come into contact with each other, and the panels (1) are not pushed down by the facing panel (1) and returned to the horizontal direction. Become.

(Effect of the Invention) As described above, according to the present invention, it is possible to temporarily install a flat floor surface in a wide range of the room by using an internal scaffold in which the floor surface of the scaffolding floor is folded in the interior construction work of a building. As a result, safe and accurate interior work can be done in a short time, and labor can be greatly saved.

In addition, since the internal scaffold closes the wide foot scene in a folded state and the legs at both ends are also automatically folded and stored on the back of the foot scene, the whole can be folded compactly, The storage and transportation space is small, and storage and transportation is easy.

Further, the procedure of assembling and folding is simple, and even narrow passages and entrances can be easily transported by using casters, and can be easily transported without scratching the floor surface. Since the internal scaffold used can adjust the height of the floor of the scaffold, it can be set to the optimum height on site according to the interior work of the building interior, making interior work easier. be able to. Further, when the panel is folded, the unequal leg trapezoidal link mechanism restricts the rotation so that the panel does not rotate more than vertically and falls to the opposite side, and holds the panel vertically and stably. Moreover, since an appropriate space can be provided between the vertically held panels, the panels do not come into contact with each other even if the panels swing during transportation / storage. This prevents the panels facing each other from being pushed down due to the contact between the panels and returning to the horizontal direction, and the panels can be stably transported and stored.
