[0002]

2. Description of the Related Art When constructing a structure or the like (hereinafter referred to as a construction target), various works are performed by assembling scaffolding so as to surround the inside or outside of the structure. Be seen. For example, if the planned construction material has a curved portion such as a circular shape or a fan shape in a plan view, if the scaffolding materials are arranged along the wall surface of the construction target material, a substantially triangular shape will be formed between adjacent scaffolding materials. A gap with a shape or trapezoid is generated.

Therefore, it has been troublesome that, for example, a properly cut veneer plate or the like is covered and tied with a wire or the like so as to close this gap, and the scaffolding materials adjacent to each other are used by using the veneer plate or the like. Was not sufficient to connect them securely.

The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to make it possible to close the gap between adjacent scaffolding materials by a simple mounting operation. The purpose of the present invention is to provide a bridging material for scaffolding that can reliably connect the adjacent scaffolding materials to each other.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a scaffolding material for scaffolding according to the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the scaffolding bridging material 10 is attached so as to pass through the gap S1 between adjacent scaffolding materials K1 and K1. The scaffolding material 10 for scaffolding is composed of a material 12 for a material to be passed over so as to cover the gap S1, and each scaffolding material K adjacent to the material 12 for a material.
1, K1 and a connecting portion 14 provided on the transfer material body 12.

In the case of this embodiment, scaffold materials K1 and K1
For example, a frame scaffold is used, and this frame scaffold, as shown in FIGS. 2 and 3, is a planned construction object Y1 having a curved portion, such as a circular storage tank, as a planned work object. Are assembled side by side along the outer wall surface side (solid line in FIG. 3). Here, the construction target Y1 refers to a state before the scaffolding material is assembled to complete the construction, but in the present invention, in a broad sense, scaffolding material is planned to be assembled for repairing the completed construction. Including constructs. Further, the work target object is not limited to a building or the like as long as it is a work (mainly a construction work) with scaffolding assembled, for example,
It may be a natural product or the like, and its target is not particularly limited. Further, the work-scheduled target may be, for example, concrete, wood, metal or the like, and the construction material is not particularly limited.

Each of these frame scaffolds is composed of a set of building frames K2, K.
2. A steel cloth plate K3 serving as a passage or a work place, a fixing brace K4, and the like. Each building frame K2 is made of, for example, a steel pipe, and is made up of a pair of pillar portions L1 and L1 which are stood apart from each other at a constant interval, and a horizontal beam portion L2 which is bridged over the pillar portions L1 and L1. . Then, one end of the steel cloth plate K3 is hung on the horizontal beam portion L2, and between the pair of building frames K2, K2,
A steel cloth plate K3 is bridged.

In the illustrated embodiment, adjacent scaffold materials K
The substantially triangular or trapezoidal gap S1 formed between the first and the first K1 is the building frame K of the adjacent scaffolds K1 and K1.
2, scaffolds K1, K1
However, due to the fact that they are arranged side by side along the outside of the construction target Y1, the gap S1 between the adjacent building frames K2, K2 is more distant than the location near the construction planned Y1. Becomes wider.

Therefore, the transfer material main body 12 is located near or away from the construction object Y1.
Corresponding to the width of the gap S1 between the scaffold materials K1 and K1,
It has a narrow upper side portion 12a and a wide lower side portion 12b, and specifically, has a substantially trapezoidal shape in a plane and a size capable of covering a gap S1 between adjacent building frames K2 and K2. ing. The width of the upper side portion 12a and the width of the lower side portion 12b are determined by the curved portion of the planned construction product Y1 when the lengthwise dimension of the scaffold K1 is constant. Depends on the curvature of. That is, as the curvature increases, the upper side portion 12
That is, in the illustrated embodiment, the shorter side closer to the construction target Y1 is further narrowed, and the lower side 12b, that is,
It is necessary to further widen the long side portion away from the construction target Y1. On the contrary, the smaller the curvature, the smaller the difference in length between the upper side portion 12a and the lower side portion 12b.

However, the main body of the bridging material 12 does not necessarily have to have a trapezoidal shape as in the illustrated embodiment, and if it has a size capable of covering the gap S1 between the scaffold materials K1 and K1, other than that. It may have a shape of. Further, the upper side portion 12a or the lower side portion 12b of the transfer material body 12 may have, for example, a curved shape.

Further, the transfer material main body 12 is composed of a mesh portion T1 made of metal such as iron and a support frame T2 surrounding the mesh portion T1 made of metal such as iron. Specifically, the support frame T2 is welded to the four sides of the net portion T1 so that the net portion T1 having a substantially trapezoidal plane shape is surrounded by the support frame T2.

In this way, the transfer material main body 12 is connected to the net portion T1.
The reason for forming from is that it works as a non-slip,
This is because the weight becomes lighter, the transportation becomes easier, and even if rain or snow falls, it falls out.

In the case of this embodiment, the net portion T1
For example, an expanded metal specified by JIS is used, but it is not necessarily limited thereto. Further, the transfer material main body 12 includes the net portion T1 and the support frame T.
The net portion T1 may be, for example, a lattice portion, or may be a flat plate on which no net or lattice is provided. Also, the support frame T
2 is not necessary. Furthermore, the material of the transfer material main body 12 does not necessarily have to be made of metal, and may be made of a material other than metal such as synthetic resin as long as it has a predetermined strength or more.

Further, the scaffolding material main body 12 is in contact with and supports the scaffolding material main body 12 from the lower side.
1 side end portion, that is, the building frame K2, the lateral beam portion L2 of K2,
As it straddles L2, it rises on both sides so as to stand up. That is, the passing material body 12
Is provided with rising portions 12c on both sides thereof, and protrudes upward so that the central portion between the rising portions 12c, 12c is substantially horizontal.

As described above, the reason why the bridging material main body 12 is protruded upward so as to stand up on both sides thereof is that the bridging material main body 12 has the gap S1 between the adjacent scaffold materials K1 and K1. When handed over to cover K
2, K2 straddling the lateral beam portions L2, L2 to prevent obstruction in the attachment, and the lateral beam portion L when the passing material body 12 serves as a passage or a work place.
The reason for this is that L and L2 are hidden below the handing material main body 12 to prevent obstacles such as passing. Also, scaffold materials K1 and K1
Since the horizontal beam portions L2 and L2 of the transfer material body 12 abut and support the transfer material main body 12 from the lower side, the transfer material main body 12 does not contact the horizontal transfer beam portions L2 and L even when a load is applied to the transfer material main body 12 from the upper side.
It will be surely supported from below by 2.

Thereby, on the steel cloth plate K3, for example,
When carrying equipment for work such as pump trucks, steel cloth plate K3
Even if it approaches the transfer material body 12 from the
Since L2 and the like do not obstruct traffic, they are easily transported.

However, the transfer material body 12 does not necessarily have the rising portions 12c, 12 as in the illustrated embodiment.
It is not necessary to project so that the space between c is horizontal. For example,
The protrusion may be formed so as to be curved as a whole, or if it is not necessary, it may be a substantially horizontal plane without protrusion.

Next, the connecting portion 14 has a width B1 of a gap S1 between the pillar portions L1 and L1 of the adjacent scaffold materials K1 and K1.
A width greater than a width B2 (see FIG. 5) obtained by adding at least a dimension corresponding to the outer diameter of each of the pillar portions L1 and L1 and allowing the pillar portions L1 and L1 to be inserted therethrough. Through holes 18, 18 are provided. In the illustrated embodiment, since the connecting portion 14 is continuously provided on the upper side 12a side of the passing material body 12, the adjacent scaffolding materials K are used.
The gap S1 between 1 and K1 means the gap S1 between the pillar portions L1 and L1 located near the construction target Y1.

Specifically, the connecting portion 14 is made of a metal plate and is attached by welding one end bent at a right angle to the support frame T2 on the side of the upper side 12a. Further, the connecting portion 14 is provided with the two through holes 18, 18 which are separated from each other in the left-right direction by a predetermined distance. By inserting the pillar portions L1 and L1 into the through holes 18 and 18, the attachment of the scaffolding material 10 for the scaffold is ensured, and the positional deviation of the pillar portions L1 and L1 is regulated, so that the adjacent scaffolds are provided. The materials K1 and K1 can be reliably connected to each other.

The pillar portions L1 and L1 are connected to the through holes 18,
4 and 5 in order to prevent rattling in 18
As shown in FIG. 3, the stopper M having a wedge-shaped lower end is provided in each of the through holes 18, 18 into which the pillars L1, L1 are inserted.
It is desirable to hit 1 with a hammer or the like to insert each. Then, in order to prevent loss and the like of the stopper M1 and to facilitate handling, the stopper M1 is connected to the net portion T1 by a tie M2 such as a rope, a string, or a chain.

However, it is not necessary for the connecting portion 14 to have a plurality of through holes 18, 18 as in the illustrated embodiment, and each scaffold material K1, K1 adjacent to the transfer material body 12 is not necessary.
If the scaffolds K1 and K1 adjacent to each other can be connected to each other, they may have a structure other than that. Further, the number of the through holes 18, 18 is the scaffold material K.
Two or more may be provided depending on the situation such as the installation site of 1, K1.

The reason why the connecting portion 14 is provided on the side of the narrow upper side 12a of the crossing material body 12 is that the position where the scaffolding materials K1 and K1 are connected is that the gap S1 between the scaffolding materials K1 and K1 is narrow. This is to correspond to. And scaffolding material K
The position where the 1, K1 are connected is set to a narrow space S1 between the scaffolds K1 and K1 because the pillar portions L1 and L1 are located in the through holes 18 and 18 as compared with the wide space S1. This is because the work of inserting becomes easier.

However, the connecting portion 14 does not necessarily have to be provided on the side of the narrow upper side 12a of the transfer material body 12,
For example, it may be provided on the side of the wide lower side 12b of the transfer material main body 12, or may be provided at a place other than that.

Next, the scaffolding material 1 for scaffolding of this embodiment
A method for connecting adjacent scaffolds K1 and K1 using 0 will be described. First, the scaffolds K1 and K1 on the lowermost stage side will be described.
Are arranged along the outside of the construction target Y1 having the curved portion. And the planned construction material Y of the scaffold materials K1 and K1
The pillar portions L1 and L1 located near 1 are connected to the connecting portion 14
The column portions L1, so as to be inserted into the individual through holes 18, 18.
The connecting portion 14 is lowered from the upper side of L1 toward the lower side, and the upper portions of the pillar portions L1, L1 are inserted into the through holes 18, 18.

The scaffold members K1 and K1 are provided with a horizontal cross section L.
2. The connecting portion 14 is lowered toward the lower side until the L2 contacts and supports the transfer material body 12 from the lower side. After that, if necessary, the scaffolding material K1 on the bottom side,
The lower end of the scaffold K1 at the lowermost stage is connected to the upper ends of the pillars L1 and L1 of K1 by connecting the lower ends of the pillars L1 and L1 of the second stage of the scaffold K1 and the pillars L1 and L1 of K1, for example, via a connecting pin. , On K1,
Stack the second-stage scaffolding materials K1 and K1. The scaffolding materials K1 and K1 of the second step are also the scaffolding material K on the bottom side
The scaffolding material 10 for scaffolding is attached like 1 and K1.
The scaffold materials K1 and K1 are similarly piled up until the required height is obtained, and the scaffolding material 10 for scaffolding is sequentially attached.

Further, the connecting portion does not necessarily have to be a metal plate provided with the plurality of through holes 18, 18 as described above. For example, the connecting portion 20 shown in FIG. 6 is attached to the lower surface side of the transfer material main body 12, and the left and right clamps W1
However, the scaffold members K1 and K1 can be connected to each other by grasping the lateral beam portions L2 and L2 of the adjacent scaffold members K1 and K1.

That is, the clamp W1 has a pin P
1, a hook portion W2 having a protruding portion P1 and the pin P1,
A movable piece W4 having guide holes P2 and P2 with which P1 engages
Consists of Thereby, when the horizontal beam portions L2, L2 are fitted into the hook portion W2, the movable piece W4 is positioned on the upper side (shown by the solid line in the figure), and the opening W3 of the hook portion W2 is formed.
To increase. In addition, in the hook portion W2, a horizontal beam portion L2,
When L2 is fitted, the movable piece W4 can be positioned on the lower side (shown by a virtual line in the figure), and the opening W3 can be made smaller so that the lateral beam portions L2, L2 do not come off from the opening W3. .

The present invention is not limited to the above-mentioned embodiment, but various modifications can be made.
For example, the scaffolding materials may be arranged along the inside (imaginary line in FIG. 3) of the work scheduled object having the curved portion. Further, the scaffolding material for scaffolding according to the present invention may be used in scaffolding materials installed in tunnel construction sites, elevated construction sites, ceiling construction sites, subway construction sites, and other construction sites. Further, the scaffold is not limited to the frame scaffold, and may be a scaffold having another structure such as a log scaffold or a single pipe scaffold.
