[0002]

2. Description of the Related Art As an assembly scaffolding unit for construction,
There is already a scaffolding unit proposed by the applicant in Japanese Patent Application No. 2-272995.

Particularly, among them, a base frame body having at least two vertical columns and two outermost vertical columns of the base frame body should be opened in a double door shape through a suitable number of horizontal members. An appropriate number of sheets that are swingably arranged in a parallel state by axially supporting at least a part of one side between the two front-mounted vertical columns that are axially supported and the two outermost vertical columns of the base frame. The scaffolding plates of the above-mentioned scaffolding plates are placed in a swinging position until they are arranged substantially horizontally, and the scaffolding plates are attached to either one or both of the above-mentioned open vertical columns or the horizontal members. , Those which can be locked and fixed have been proposed.

In this scaffolding unit, a scaffold used for building a building can be assembled very easily with a small number of constituent members and good operability.
It has been well-received as it has various excellent effects such as the space required for storage can be minimized.

[0005]

However, such an excellent scaffolding unit also has the following problems.

[0006] That is, in the position where the scaffolding plates are rocked until they are arranged substantially horizontally, the forward-moving vertical columns, which are opened,
Alternatively, it may not be possible to secure sufficient mounting strength of the scaffolding plate depending on the location only by forming it so that it can be locked and fixed to either or both of the horizontal members.

Therefore, in that case, the scaffolding plate is reinforced by a separate member each time, but the work is troublesome and the scaffolding unit can be easily assembled, while the scaffolding plate is reinforced. Since it takes time and effort, the improvement has been desired.

In view of the above-mentioned problems and the like, the present invention has a very simple structure and is easily assembled and the scaffolding plate has sufficient attachment strength. In addition, it can be folded and stacked. In the case of storage, it was created as an issue to provide a scaffolding unit that can reduce the collapse of cargo and arrange it well.

[0009]

Therefore, the present invention is
A base frame body having at least two vertical frames, and the outermost vertical frame among the vertical frames as vertical columns, respectively, and swings through the appropriate number of horizontal members on these vertical columns to open in a double-door shape. It consists of two front vertical columns that are axially supported in an appropriate manner and a suitable number of scaffolding plates that pivotally support at least a part of one side between the vertical columns and are swingable in a parallel state. Scaffolding board
The scaffolding plate is formed so that it can be locked and fixed to either one or both of the open front vertical column and the horizontal member that are opened in a position where they swing until they are arranged substantially horizontally. Are connected to either one or both of the above-mentioned vertical columns or the horizontal members, which are connected to each other so as to be swingable so that they can be rocked and fixed together with the scaffold plate. The above-mentioned problems are solved by forming it so that it can be fixed.

Further, a short rod-shaped body, a substantially cylindrical body, or a substantially cylindrical body, in which a shaft support member for swingably supporting a horizontal member on a vertical support is attached to the vertical support at a substantially right angle to the front, is formed. The member is formed by appropriately notching the one end of a horizontal member swingably supported at a substantially intermediate portion of the member, and the tip end portion of the shaft supporting member is stacked in a state where the front vertical column is closed. At this time, the above-mentioned problems are solved by forming the vertical pillars in a concave shape so that the peripheral surfaces thereof match.

[0011]

When the scaffolding unit according to the present invention is assembled, first, the two front projection vertical columns are opened in a double-sided open state.

Then, an appropriate number of scaffolding plates are swung, and fixed by locking either one or both of the opened front columns or the horizontal members.

At that time, the scaffolding plate is placed at the position where the forward vertical columns are opened so that the horizontal members are substantially perpendicular to the vertical columns of the base frame, and the forward vertical columns or the horizontal members are By locking and fixing to either or both of them, a total of four columns of two front vertical columns and two vertical columns are arranged at the four corners of the scaffolding board to be assembled and self-supporting. is there.

When a suitable number of scaffolding plates are rocked and locked, the reinforcing support members swingably connected to the scaffolding plates are simultaneously opened with the above-mentioned vertical columns or the horizontal bridges. It is locked and fixed to either one or both of the materials. Thereby, it can withstand the strength sufficiently.

Further, a shaft-supporting member for swingably supporting a horizontal member on a vertical column is attached to the vertical column at a substantially right angle to the front, and is a short rod-shaped body or a substantially cylindrical body or a substantially cylindrical body. The member is formed by appropriately notching the one end of the horizontal member swingably supported in the substantially middle portion of the member, and the tip end portion of this shaft supporting member is piled up when the front vertical column is closed. If the vertical pillars are formed in a concave shape so that the peripheral surfaces of the vertical pillars coincide with each other, the vertical pillars are matched and supported when the concave portions are stacked, so that the load collapse can be reduced and the arrangement can be favorably performed.

[0016]

Embodiments of the present invention will be described below with reference to the drawings.

That is, the reference numeral 1 shown in the drawing is a base frame body, and has a vertical column 2 composed of at least two pipes,
These vertical columns 2 are connected by a plurality of horizontal rods 3 to form a rectangular shape. At this time, the horizontal rod 3 is strengthened in strength by the truss structure.

Then, an appropriate number of columns are provided on each of the two outermost vertical columns 2 of the base frame 1, and in the case of the figures, 3 columns each.
The horizontal members 4 are pivotally supported at right angles to the vertical columns 2 so as to be swingable in the circumferential direction of the vertical columns 2. The horizontal members 4 have the same length as the vertical columns 2. The front column 5 of the above, vertical column 2
Fix them so that they are arranged parallel to each other, one for each vertical column 2. As a result, the front vertical column 5 is attached to the base frame 1 via the horizontal member 4 so as to open in a double door shape.

With respect to the axial support state of the horizontal member 4, the horizontal member 4 is axially supported by the shaft support member 6, as shown in FIG.

The shaft support member 6 is formed by appropriately cutting out a short rod-shaped body, a substantially cylindrical body, or a substantially cylindrical body member which is attached to the vertical strut 2 at a substantially right angle to the front. A tubular member is appropriately cut out, and a shaft support portion 6b that pivotally supports one end of the horizontal member 4 is formed in a substantially middle portion thereof, and the shaft support member 6b is formed at this shaft support portion 6b. Against horizontal material 4
To support.

The tip end portion of the shaft support member 6 forms a concave engaging portion 6a with which the peripheral surface of the vertical column 2 is aligned when the front vertical column 5 is stacked in a closed state. Thereby,
Since the horizontal member 4 is pivotally supported at a substantially middle portion, the engaging portion 6a of the shaft support member 6 is located on the horizontal member 4 and the front vertical column when the front vertical column 5 is closed. If the vertical strut 2 that is slightly protruding further than 5 and is stacked in a state where the front vertical strut 5 is closed, the vertical strut 2 to be stacked next is engaged with the engaging portion 6a at the tip end thereof, the load collapses. There is no need to organize it.

On the other hand, between the two outermost vertical columns 2 of the base frame 1, an appropriate number of, in the illustrated case, three rectangular scaffolding plates 7 are provided at the positions of the horizontal members 4. At least a part of one side, in the illustrated case, both ends are pivotally supported, and three scaffolding plates 7 are separately arranged in parallel in a swingable manner.

These scaffold plates 7 are swung until they are arranged substantially horizontally, whichever of the above-mentioned forward-standing vertical column 5 or the horizontal member 4 in that state is opened. One or both of them is formed so as to be locked and fixed. In a concrete locking state, for example, as shown in FIG. 4, a locking portion 11 is formed, and the locking portion 11 is
A locking piece 11b is formed on the scaffolding plate 7, and the front vertical column 5
A small frame-shaped locking body 11a into which the locking piece 11b can be inserted is formed, and the locking piece 11b is inserted into the locking body 11a in a state where the scaffold plate 7 is horizontal by swinging. And lock. For the locking, a pin is provided on the locking body 11a toward the inside of the frame, and a notch into which the pin can be inserted is provided on the locking piece 11b. Locking body 1
When it is inserted into 1a, the pin of the locking body 11a engages with the notch of the locking piece 11b to be inserted and locked.

[0024] Further, each of the scaffolding plates 7 is swingably connected to a reinforcing support member 9, and the front vertical column 5 or the horizontal bridge member 5 which is opened while the scaffolding plate 7 is locked and fixed. It is formed so that it can be locked and fixed to either one or both of the four.

As shown in FIG. 4, the concrete structure of the scaffolding plate 7 is that the end face of the scaffolding plate 7 is framed so as to form a substantially triangular shape by a supporting member 9 which is a hypotenuse and a vertical rod 8. Is provided with a locking piece 12b at the tip so as to be locked and fixed to the locking portion 12 provided on the front vertical column 5.

The locking portion 12 is a small frame into which the locking piece 12b can be inserted, and the fixing screw 12a is screwed from the outside toward the inside.
The fixing screw 12a is inserted and locked in the notch formed in the locking piece 12b in the state of being inserted in 2.

The supporting member 9 and the vertical rod 8 thus formed are pivotally supported on the end faces of the scaffolding plates 7 so that they can swing freely. The surface is folded in a U shape so as to have a slight thickness so as to also serve as a reinforcement, and the vicinity of the tip of the shaft support member 10 is fixed to this front end surface, and at the lowermost part of the end surface. Vertical rod 8,
Each of the supporting members 9 is axially supported.

By doing so, the scaffolding plate 7 is slightly used.
Since the end face has a width corresponding to the thickness in the up-down direction, when the scaffolding plate 7 swings to a substantially horizontal position, the vertical rod 8 and the tip of the supporting member 9 come into contact with the upper end edge of the end face of the scaffolding plate 7. It prevents the plate 7 from further swinging downward.

In assembling the scaffolding unit S formed in this way, first, the two front-side vertical columns 5 are opened in a double-opening state.

Then, an appropriate number of scaffolding plates 7 are swung, respectively, and fixed to either one or both of the opened front columns 5 or the horizontal members 4 or both. Assemble with At the same time, each support material 9
Is swingably connected to the scaffolding plate 7, and is fixed to either one or both of the front vertical column 5 and the horizontal member 4 which are opened together with the fixing.

At that time, the scaffolding plate 7 is placed at a position where the forward-moving vertical columns 5 are opened so that the horizontal members 4 are substantially perpendicular to the vertical columns 2 of the base frame 1, Or the horizontal member 4
If either one or both of them is locked and fixed, 2
A total of four columns, which are a front vertical column 5 of a book and two vertical columns 2 are arranged at four corners of the scaffolding plate 7 to be assembled and self-supporting.

In the storage of the scaffolding unit S, first, as shown in FIG. 2, either one of the scaffolding plate 7 and the supporting member 9 and the front vertical column 5, or the horizontal member 4 or By releasing the lock with both and making all three scaffolding boards 7 reach the vertical column 2 side respectively, and then approaching the front vertical column 5 close to the base frame 1 side, It can be folded into the state shown in FIG. Therefore, when stored,
It is thin enough to look like a plate, and when assembled
This is a scaffolding unit S having four columns.

In this state, as described above, the shaft support member 6
The portion of the engaging portion 6a of the above protrudes slightly from the horizontal member 4 and the forward-moving vertical strut 5, and when the forward-moving vertical strut 5 is piled up in a closed state, Stacking vertical columns 2
By engaging with each other, it is possible to satisfactorily organize the load without collapsing the load.

Reference numeral 13 in the drawing is a ladder vertically fixed to the side surface of one of the forward-moving vertical columns 5 so that an operator can easily come and go to each scaffolding plate 7 in the assembled state. is there.

In the scaffolding unit S assembled in this way, the worker may be allowed to walk directly on the scaffolding plate 7, but in reality, although not shown, a long and narrow wooden scaffolding plate is used for each of the scaffolding plates. When the scaffolding units S are connected in parallel in the lateral direction, if the scaffolding units S are connected in a lateral direction, even if there is a slight step, the wooden boards are placed on the plank 7 when the scaffolding units S are connected in parallel. Since it can be covered with the scaffolding plate 19, it is possible to ensure safety when the building material is transported and the worker walks.

In this case, instead of the wooden scaffolding plate, a square scaffolding connecting plate having the same width as the scaffolding plate 7 or a slightly narrower width is arranged between the scaffolding units S, although not shown. However, the scaffolding units 7 may be connected to each other on the scaffolding by extending the connecting scaffolding plate between the scaffolding plates 7. In this case, a plurality of connecting hooks (not shown) are provided on the end surface of the connecting scaffolding plate, and the connecting hooks are hooked to the horizontal members 4 of the respective scaffolding units S so that the scaffolding units S can be connected to each other. You may make it connect. At this time, it is convenient that the connecting hook is easily hooked on the horizontal member 4 by appropriately providing a notch on the side of the scaffolding plate 7.

On the other hand, the scaffolding unit S formed in this way
It is very convenient to do the following in order to connect in parallel directly in the horizontal direction.

That is, as shown in FIG. 6, the advancing vertical columns 5 of the adjacent scaffolding units S and the vertical columns 2 of the base frame 1 are connected by the connecting foot member 14.

The connecting foot member 14 has a height adjusting foot portion 15 whose height can be adjusted by a turnbuckle structure at the lower end of a single rod, and has a vertical column 2 or a vertical pillar 2 formed of a pipe or the like at the upper end. A connecting portion 16 having a structure in which two fitting pins that can be fitted into the front-side vertical columns 5 are erected close to each other is formed.

With this connecting foot member 14, the height of the scaffolding unit S is appropriately adjusted by the height adjusting foot portion 15, and then the adjoining forward vertical columns 5 of the adjacent scaffolding units S are adjoined.
The height adjustment and connection of the scaffolding unit S are performed at the same time by inserting the fitting pins of the connecting portion 16 from the lower ends of the vertical columns 2 of the base frame 1 and the vertical columns 2 of the base frame 1.

Needless to say, the scaffolding unit S according to the present invention is not limited to the above-mentioned embodiment.
