[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a scaffolding device for forming a working scaffold when building a building such as a building or a ship.

[0002]

2. Description of the Related Art Conventionally, when a building such as a building or a ship is constructed, a work scaffold is provided, and various scaffolding devices have been proposed.

[0003] Among them, what is referred to as a frame scaffold is frequently used today. In general, the frame scaffold has a gate-shaped vertical frame material arranged at appropriate intervals in a horizontal direction and is adjacent to each other. The vertical frame members are connected to each other by horizontal members, and the frame members are formed by connecting the vertical frame members in an arbitrary number of stages in the vertical direction as necessary.

[0004] A connecting member is disposed between the vertical frame members which are vertically continuous in an arbitrary number of stages in the vertical direction to ensure the integrity, and between adjacent vertical frame members in the horizontal direction. The cross braces are arranged to ensure independence.

[0005] Therefore, according to the scaffolding device as the above-mentioned conventional proposal, the vertical frame member, the horizontal member, the connecting member, the cross brace, and the like are appropriately prepared, and these are combined in a predetermined manner. Thus, a work scaffold of a desired size can be obtained.

[0006]

However, the following inconveniences have been pointed out in the above-mentioned conventional scaffolding device.

That is, in the above-described conventional scaffolding device, portal-type vertical frame members are arranged at appropriate intervals in the horizontal direction, and adjacent vertical frame members are connected by a horizontal member. Since it is configured, the plane shape of the frame is limited to only a rectangle, and the plane shape of the frame cannot be set to a trapezoid or another quadrilateral.

Therefore, when it is necessary to set a work scaffold having a plane shape other than a rectangular shape based on the shape of a building or the like, this can only be realized by using another member such as a steel pipe and a clamp having an appropriate length. In addition, it is not only necessary to prepare various members, but also the assembly work becomes complicated.

[0009] In the above-mentioned conventional scaffolding device,
Since the scaffolding plate is erected at the upper end of the vertical frame material, when assembling or disassembling the work scaffolding, workers who stand on the topmost scaffolding plate rely on their own body unless a handrail is provided. There is nothing and there is always a danger of falling.

Further, in the above-mentioned conventional scaffolding device, the vertical frame members adjacent to each other in the horizontal direction are connected by cross braces arranged there, so as to secure the independence as one frame. However, only the connecting member is arranged between the frames that are continuous in the vertical direction, and the integrity of the upper and lower frames is not ensured.

Therefore, in the above-mentioned conventional scaffold device,
In order to secure the strength, it is necessary to prepare various other connecting auxiliary members, and the number of members is increased, so that maintenance and management thereof are troublesome.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is, of course, to be optimal for forming a desired working scaffold at the time of building a building. Another object of the present invention is to provide a scaffolding device that can be assembled and disassembled in a safe manner and can avoid an unnecessary increase in the number of members.

[0013]

In order to achieve the above object, the structure of the present invention is to form a frame with a vertical frame member connected in an arbitrary number of stages in the vertical direction, and to move the frame in the horizontal direction. In a scaffolding device in which a scaffold plate is erected between each frame and cross braces are erected on at least the front side of each frame, the vertical frame members stand upright in the front-rear direction. A pair of vertical members, a horizontal flange body integrally provided at the upper end and the intermediate part of each vertical member, and each end part is integrally connected to each horizontal flange body by being bridged between the horizontal flange bodies at each intermediate part. A scaffold plate is detachably mounted between the cross members, and the upper end of each cross brace is detachably connected to the horizontal flange body at the upper end of the upper vertical member and each cross member is connected. The lower end of the brace is detachably connected to the middle horizontal flange of the lower vertical member And it is characterized in that they are. In this case, it is preferable that the lower vertical frame member is connected to a base unit including a base member and a horizontal brace connected to the base member. Similarly, it is preferable that the horizontal flange body is formed in a dovetail shape in cross section and has an annular locking portion at a peripheral portion.

[0014]

[0015]

[0016]

Therefore, a vertical frame member is connected to the upper end of a base unit disposed on a predetermined ground or the like, and a scaffold plate is erected between the horizontal members of the vertical frame member.

At this time, if the plane shape of the frame is not rectangular, the plane shape of the base unit is set to a predetermined shape in advance.

An intersecting brace is arranged between the upper vertical frame member and the lower base unit to integrate the upper vertical frame member and the lower base unit.

Also, handrails are connected between the vertical members to be arranged in a so-called vertical and horizontal direction.

Next, a vertical frame member is connected to the upper end of each vertical frame member from above, a scaffold plate is connected between the connected vertical frame members, and the upper and lower vertical frame members are connected to each other. A cross brace is arranged between the two to achieve the integration.

A handrail is connected between the vertical members to be arranged in the vertical and horizontal directions at the uppermost stage.

[0022]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a scaffolding device according to the present invention has a vertical frame member (1, 1) connected in an arbitrary number of stages in the vertical direction.
A scaffold in which the frames are arranged to face each other in the lateral direction, a scaffold plate is erected between the frames, and a cross brace is erected on at least the front side of each frame. A vertical frame member (1, 1) includes a pair of vertical members (10, 10) standing upright facing each other in the front-rear direction, and an upper end portion and an intermediate portion of each vertical member (10, 10). Horizontal flange body (1
2,12) and the horizontal flange body (12,1
2) Each end of each horizontal flange body (12.
12) and a cross member (11) integrally connected thereto, a scaffold plate (4) is detachably mounted between the cross members (11, 11), and the upper end of each cross brace (3) is located at the upper stage. Vertical material (1
0) The upper and lower horizontal flanges (12, 12) are detachably connected to the upper horizontal flanges (12, 12), and the lower ends of the cross braces (3) are intermediate horizontal flanges (12, 12) in the lower vertical member (10). Is removably connected to the In this case, the lower vertical frame member is connected to a base unit (5) including a base member (50) and a horizontal brace (53) connected to the base member (50). Similarly, the horizontal flange body (12) is formed in a dovetail-shaped cross section, and has an annular locking portion (12a) at the periphery.

As shown in FIG. 2, the vertical frame member 1 includes a pair of vertical members 10 and a horizontal member 1 for connecting an intermediate portion between the pair of vertical members 10.
1 and is formed so that its front shape assumes an H-shape.

The vertical member 10 is made of a steel pipe having an appropriate outer diameter, is set to have a length substantially the same as that of a frame of this type, and has an outer periphery at an upper end portion and an intermediate portion. Horizontal flange body 1 formed to have an annular shape
2 are integrally connected.

In the illustrated example, the horizontal flange body 12 is also integrally connected to the outer periphery of the lower end of the vertical member 10.

The cross member 11 is also made of a steel pipe having an appropriate outer diameter, and is set so as to have substantially the same length as a member generally used as a cross member in this type of frame. When the vertical frame members 1 are disposed at appropriate intervals in the horizontal direction, the scaffold plates 4 can be erected between the horizontal members 11 that are adjacent to each other in the horizontal direction, that is, between the horizontal members 11. Is formed.

The horizontal member 11 is fixedly connected at both ends thereof to a horizontal flange body 12 provided at each intermediate portion of the pair of vertical members 10 by welding or the like.

In the illustrated example, the cross member 11 is connected to the vertical member 10 and is reinforced by a cheek stick member 13 disposed between the horizontal member 11 and the vertical member 10.

On the other hand, the vertical member 10 projects horizontally in the outer periphery of the middle portion thereof, that is, on the outer periphery below the horizontal flange body 12 provided continuously with the middle portion. And a cross brace 3 described later is connected to the locking pin 14.

Further, in the above-mentioned cross member 11, the locking pin 1 protruding forward in the horizontal direction on the outer periphery of both ends.
5 and the pin 15 has a cross brace 2 to be described later.
Are linked.

A handrail 6 to be described later is connected to a horizontal flange body 12 provided at the upper end of the vertical member 10.

As shown in FIGS. 3 and 4, the horizontal flange body 12 is formed so as to have a dovetail-shaped cross section. And an annular locking portion 12a.

The horizontal flange body 12 enables the connecting member 12a to be connected to a horizontal member H, which is another member formed in a form as shown in FIG. 4, for example.

That is, the horizontal member H has, at both ends thereof, shoes S formed so as to sandwich the horizontal flange body 12, and the shoes S are retracted when the wedge W is immersed therein. When the wedge W retreats, it has a hook Fs that moves forward by the urging force of the spring Ss.

The hook Fs is formed so that its tip engages with the locking portion 12a when the hook Fs is retracted.

When the wedge W is driven into the shoe S, the tip of the shoe S comes into close contact with the outer periphery of the longitudinal member 10.

The horizontal flange body 12 is constructed such that the inner peripheral side thereof is continuously connected to the outer periphery of the vertical member 1 by welding.

Therefore, for example, when the horizontal member H, which is another member connected to the vertical member 10 via the horizontal flange member 12, has the shoe S connected to the horizontal flange member 12, When the wedge W is driven into the shoe S,
The shoe S, that is, the horizontal member H can be connected to the vertical member 10.

As shown in FIG. 5, the cross brace 2 has a main body 20 and connecting portions 21 formed at both ends of the main body 20.
The main body 20 is made of a steel pipe having an appropriate outer diameter, and a central portion thereof is pivotally connected with a caulking pin 22 so as to be so-called foldable.
Is formed so as to crush both ends of the steel pipe as the main body 20.

The connecting portion 21 has a pin insertion hole 21a formed so as to penetrate the thickness thereof, and the pin insertion hole 21a is formed in the horizontal member 11 constituting the vertical frame member 1. The diameter is set so as to allow the continuous insertion of the locking pin 15.

On the other hand, the cross brace 3 is basically configured in the same manner as the cross brace 2 described above.
Since the installation location is different, only the basic length is different, and therefore, in FIG.
The caulking pin 32 and the pin insertion hole 31a are indicated together and their detailed description is omitted.

In the cross brace 3, the connecting portion 3
It goes without saying that the locking pin 14 connected to the vertical member 10 constituting the vertical frame member 1 is inserted into the pin insertion hole 31a formed by drilling.

Therefore, while the cross braces 2 are arranged between the vertical frame members 1 that are continuous in the vertical direction, the cross braces 3 are vertically adjacent to each other while being adjacent to each other in the horizontal direction. When forming a so-called framed scaffold using the vertical frame material 1, the vertical frames are arranged at appropriate intervals in the horizontal direction and are continuously arranged in an arbitrary number of stages in the vertical direction. The frame material 1, that is, the integrity of the frames is secured.

The horizontal member 11 constituting the vertical frame member 1, ie,
The scaffolds 4 are erected between the horizontal members 11 that are adjacent to each other in the horizontal direction by disposing the vertical frame members 1 in the horizontal direction.
There is no particular limitation on the configuration of the scaffold plate 4.

However, in the illustrated example, the scaffold plate 4 has a plurality of hooks 41 connected to an end in the axial direction of the main body portion 40 as a tread plate portion. The erection is configured to be realized by being locked.

Although not shown, the scaffold plate 4 is formed so that its main body 40 is extendable or retractable, or the hook 41 is formed so as to be able to protrude and retract from the main body 40. It is preferable to be formed so that expansion and contraction can be adjusted.

As shown in FIG. 1, the vertical frame member 1 is disposed so as to be connected to the base unit 5 at the time of installation, and the base unit 5 is basically provided. It is sufficient to have the base member 50 formed in a jack structure.

However, in the illustrated example, the base unit 5
Has long and short horizontal members 51 and 52, a horizontal brace 53, and an auxiliary vertical member 54 in addition to the base member 50.

To explain a little, the base member 50 only needs to be connected to the lower end of the vertical member 10 so as to be able to set the reference height of the vertical member 10, that is, the vertical frame member 1, In the illustrated example, it is formed to have a base plate 50a and a handle 50b.

The height of the upper end of the base member 50 can be changed by rotating the handle 50b.

The base member 50 has a horizontal flange 50c formed on the outer periphery thereof above the handle 50b so as to have the same plane shape as the horizontal flange 12 in the illustrated example. The horizontal flange 5
The connection of the horizontal members 51 and 52 is enabled through Oc.

An auxiliary vertical member 54 is connected to the upper end of the base member 50 in the vertical direction.

The horizontal members 51 and 52 are so-called connecting members that connect the base members 50 to be arranged vertically and horizontally to each other, and are the horizontal members H shown in FIG.
As in the case of (1), it is formed so as to be connected to the base member 50 by using a wedge W.

The horizontal member 51 is disposed between a pair of base members 50 disposed in a so-called short direction.
Is disposed between a pair of base members 50 disposed in a so-called longitudinal direction.

In the illustrated example, the horizontal member 51 is provided with a locking pin 51a in the same manner as provided on the horizontal member 11 constituting the vertical frame member 1. The lower end, which is one end of the cross brace 2, is connected to the locking pin 51a.

The horizontal members 52 arranged in the longitudinal direction are provided.
May be configured such that its length can be freely changed.

The horizontal braces 53 are composed of base members 50 arranged at so-called four corners and long and short horizontal members 5 connected thereto.
It is arranged to prevent deformation of the quadrilateral formed by 1, 52.

The horizontal brace 53 has a main body 53a formed to be extendable and contractable, and an end of the main body 53a is a pipe holding the horizontal flange 50c in the base member 50. It is described that the body 50d is integrally connected to the body 50d by welding or the like.

In the horizontal brace 53, it is assumed that the end of the main body 53a has a shoe S similarly to the horizontal member H shown in FIG.
0 may be connected to the horizontal flange 50c.

In the illustrated example, the horizontal brace 53
Is formed so as to be extendable and contractible. This is a result of considering that the frame formed using the vertical frame member 1 can be used even when the plane shape is not rectangular. Therefore, when the planar shape of the frame formed using the vertical frame member 1 is rectangular, the horizontal brace 53 may be formed in a fixed form in advance.

The auxiliary vertical member 54 is a so-called length adjusting member that enables the cross brace 2 to be disposed between the horizontal member 51 and the horizontal member 11 in the upper vertical frame member 1. The pipe member 5 of the base member 50
When 0d is formed to have a predetermined length, its arrangement may be omitted.

However, in the case where the auxiliary vertical members 54 are arranged as in the illustrated example, the base member 50 can be shortened, and there is an advantage that the handling is easy.

The auxiliary vertical member 54 is connected to the vertical frame member 1.
As in the case of the vertical member 10, the locking pin 54 a is laterally protruded in the horizontal direction.
4a, the lower end of the cross brace 3 can be locked.

The handrail 6 is a vertical member 1 constituting the vertical frame member 1.
The upper and lower horizontal members 5 of the base unit 5 are connected to a horizontal flange body 12 continuously provided at the upper end of the base unit 5.
Like 1 and 52, they are arranged in a so-called short direction and a long direction.

The handrail 6 has shoes S on both sides on the upper end side, like the horizontal member H shown in FIG. 4, and is connected to the upper end of the vertical member 10 by using a wedge W. Is connected to the horizontal flange body 12.

The handrail 6 may be connected directly to the upper end or the like of the vertical member 10 by using a clamp or the like, instead of the illustrated example.

The handrail 6 has a skirting board 60 at the lower end in the illustrated example, but the skirting board 60 can be freely arranged.

The scaffold device according to this embodiment formed as described above is assembled as follows.

First, the base unit 5 is arranged on a predetermined ground or the like. At this time, each base member 50 constituting the base unit 5 is tilted by using the horizontal members 51 and 52 and the horizontal brace 53. For example, it is positioned at so-called four corners of a predetermined rectangular plane.

At this time, if the height positions of the upper ends of the base members 50 do not coincide with each other horizontally, the handle 50b is rotated to adjust the height.

When the plane shape of the frame is not rectangular, it goes without saying that the plane shape of the base unit 5 is set in advance to a shape other than a predetermined rectangle.

Next, the upper end of the auxiliary vertical member 54 of the base unit 5 is connected to the lower end of the vertical member 10 of the vertical frame member 1, and the vertical frame member 1 is connected to the base unit 5.

Next, the vertical frame members 1 are connected to the upper end of each vertical frame member 1 from above, and the scaffold plate 4 is connected between the connected vertical frame members 1.

Then, the upper vertical frame member 1 and the lower vertical frame member 1
Cross braces 2 and 3 are arranged between them so as to integrate them.

Lastly, the handrail 6 is connected between the vertical members 10 which are arranged in the so-called vertical and horizontal directions at the uppermost stage.

With the above operations, the scaffolding device is completed, and an operator enters on the scaffold plate 4 and is used for a predetermined operation.

Further, at the time of assembling and disassembling the scaffolding device, the scaffolding plate 4 is disposed at the intermediate portion of the vertical frame member 1, so that the assembling or disassembling worker has a periphery. At least, the vertical member 10 constituting the vertical frame member 1 is present, so that there is always a place where the worker can leave himself.

In the above operations, the horizontal flange 12
In order to connect the horizontal members 51 and 52 and the handrail 6 as another member to the other members, when the shoe S is connected to each member, it is only necessary to drive the wedge W into the shoe S. .

The horizontal member 55 has locking pins 55a protruding in the horizontal direction at both ends thereof.
The cross brace 3 is locked to the locking pin 55a.

Further, in the illustrated example, the horizontal flange 12 provided at the upper end of the vertical member 10 constituting the uppermost vertical frame member 1 is provided with a short horizontal member 51 and the long horizontal member 51. The frame member 55 is linked.

In this embodiment, it is needless to say that it is assembled in the same manner as in the above-described embodiment.

[0088]

According to the present invention, the following effects are obtained. (1) Since the vertical frame member is integrally formed of two vertical members and a horizontal flange member provided at an intermediate portion between the vertical members and a horizontal member integrally connected to the horizontal flange member, the entire frame member is made of H. It is formed into a mold and can be assembled, dismantled, stored, and transported together. (2) Since each of the vertical members has a horizontal flange at the upper end portion and the intermediate portion, a handrail, a horizontal member, and a cross brace can be connected through the horizontal flange member. In this case, the crosspiece can be connected to the same horizontal level as the crosspiece. In addition, another frame body can be connected in the lateral direction, the front-rear direction, or the oblique direction via the horizontal member, and other scaffolding devices can be continuously connected in various directions according to the state of the construction site. (3) A scaffold plate is erected on the horizontal member connected to the horizontal flange member at the intermediate portion, and the upper end of the vertical member stands up even if no handrail is provided above the scaffold plate. Can be used as a member for connecting a stable belt.

Further, according to the present invention, the vertical frame members which are arranged in the vertical direction and which are continuous in the vertical direction and which are arranged in the horizontal direction and which are adjacent to each other in the horizontal direction and are vertically arranged. Since the intersecting braces are arranged between them, there is an advantage that the integrity of the upper and lower frameworks can be easily secured.

According to the present invention, since the integrity of the upper and lower frameworks can be ensured by the arrangement of the cross braces, it is not necessary to secure the strength by using other various connecting auxiliary members. In addition, the number of members can be reduced, and there is an advantage that maintenance and management thereof can be simplified.

Further, according to the present invention, since the vertical member constituting the vertical frame member is formed by connecting the horizontal flange body formed annularly on the outer periphery thereof, the horizontal frame member disposed in the longitudinal direction is formed. While the length is set freely, other members connected to the horizontal flange body including the horizontal member at both ends thereof have, for example, a free planar shape when having a wedge-based detachable structure. There is an advantage that a framework scaffold, that is, a work scaffold can be quickly provided.
