Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding scaffold cloth used in building construction work.

[0002]

2. Description of the Related Art In the construction of houses and the like, building materials are built around the building or at necessary places at intervals, and a scaffold cloth board receiving member (referred to as a carrying frame). ) Is attached to the building material, and a scaffold cloth board of a fixed size corresponding to the interval between the building materials is passed over the scaffold cloth board receiving member. Workers walk across the scaffold slabs and carry out construction work.

[0003] In the conventional scaffolding device, if the spacing between the building materials corresponds to the fixed size of the scaffolding slabs, the scaffolding slabs can be sequentially laid without overlapping. .

However, in practice, the length of a building,
Depth dimensions, shapes, and the like vary. In addition, the shape and size of the site where the scaffold is to be built differ from site to site.
Moreover, under such conditions, it is necessary to set the distance between the building and the scaffold to a predetermined size.

[0005] For this reason, it is difficult to maintain the arrangement interval of the building materials over the entire circumference of the scaffold so as to have a size corresponding to the standard size of the scaffold cloth. At the same time, there is a space between the building materials that does not correspond to the fixed-size dimensions of the scaffold cloth.

Conventionally, in such a case, two scaffold cloth boards are arranged such that one ends in the length direction overlap each other. For this reason, a step is generated between two overlapping scaffolding boards, and an operator walking on the scaffolding board has a risk of tripping over the step and causing a crash.

In addition, as a means for preventing the scaffolding cloth plate from blowing up due to strong winds or the like, it is necessary to fix the overlapping portion of the two scaffolding cloth sheets with a wire called a line. For this reason, the work of laying the scaffold cloth was troublesome.

Recently, a technique has been known in which a metal cover is placed over the above-mentioned step to eliminate the step. However, when the surface of the metal cover is slippery due to rainfall, snowfall, frost, or the like, the worker may slip on his / her feet, and there is still a risk of a crash.

[0009]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a slide type scaffolding cloth board and a scaffolding apparatus which can follow a change in the interval between building materials.

Another object of the present invention is to provide a highly secure slide type scaffolding cloth board and scaffolding device which can follow a change in the interval between building materials without causing a step which may cause a walking obstacle for an operator. It is to provide.

[0011]

In order to solve the above-mentioned problems, a sliding scaffold cloth board according to the present invention includes a first cloth board member and a second cloth board member.

[0012] The first cloth plate member includes a first tread plate, a storage space, and a guide portion. The storage space,
The first tread plate is formed below the first tread plate, and the first tread plate is formed under the first tread plate.
One end of the tread surface plate in the length direction is open. The guide portion is arranged at least on both sides of the first tread plate in the width direction of the first tread plate in the storage space,
And it extends in the length direction.

[0013] The second cloth plate member includes a second tread plate, is inserted into the storage space through the opening of the storage space provided in the first cloth plate member, and is connected to the second tread plate. The tread plate is adjacent to the first tread plate, and both sides in the width direction are supported by the guide portion and guided in the length direction.

As described above, the guide portions provided on the first cloth plate member are arranged at intervals on both sides in the width direction and extend in the length direction in the storage space. The second cloth plate member is inserted into the storage space through the opening of the storage space provided in the first cloth plate member, supported by the guide portion, and guided in the length direction. According to this structure, the length of the entire scaffolding cloth plate can be variably adjusted by expanding and contracting the first cloth plate member and the second cloth plate member in the length direction. Therefore, even when the interval between the building materials does not correspond to the fixed size of the scaffolding board, it can be dealt with by one scaffolding board.

[0015] The second tread is adjacent to the first tread. According to this structure, between the surface of the first cloth plate member and the surface of the second cloth plate member, a small amount substantially corresponding to the thickness of the first tread plate of the first cloth plate member. Only a step is created. This step has such a size that it can be almost neglected in comparison with a conventional step caused by stacking two independent scaffold cloth boards. That is, according to the present invention, the step can be substantially eliminated. For this reason, a worker who walks on the scaffold cloth does not trip on a step, and thus a highly safe scaffolding device that can avoid a danger of falling can be realized.

Further, according to the present invention, the work of laying the scaffolding slab is significantly simplified because the work of bundling the track is unnecessary.

Further, according to the present invention, there is no need to use a metal cover for eliminating a step, so that an operator does not slip on his / her feet, and thus a highly secure scaffold capable of avoiding the danger of falling. The device can be realized.

The slide type scaffolding cloth board according to the present invention comprises an intermediate socket for a scaffolding pipe,
It can be used in combination with a terminal socket for a scaffold pipe, a corner / bracket, an adjusting connection member between building materials, an arc-shaped corner connecting member for a scaffold, or the like.

The slide type scaffold cloth board 3 arranged between 0-53 will be described as a representative, and other building materials 50-51, 50-52, 50-
Regarding the slide-type scaffolding cloth plate 3 arranged between 54,
Description is omitted.

The first guide portion 141 and the second guide portion 142 provided on the first cloth plate member 1
Are arranged at intervals on both sides in the width direction W and extend in the length direction L. The second cloth plate member 2 has a storage space 13 provided in the first cloth plate member 1.
Is inserted into the storage space 13 through the opening of the storage space 13. Each of the two side plates 221 and 222 is supported by the first guide portion 141 and the second guide portion 142,
It is guided in the length direction L (see FIG. 3). According to this structure, the length of the entire sliding type scaffolding cloth plate 3 can be variably adjusted by extending and contracting the first cloth plate member 1 and the second cloth plate member 2 in the length direction L. Therefore, the building material 50
The distance d2 between −53 is the length dimension d1 of the fixed-length scaffold cloth board 6.
Even if it does not correspond to (see FIG. 8), one slide type scaffold cloth plate 3 can be used.

The second tread plate 2 includes a first tread plate 11
Is adjacent to According to this structure, the first cloth plate member 1
And a small step ΔG (see FIG. 3) substantially corresponding to the thickness of the first tread plate 11 of the first cloth plate member 1 between the surface of the second cloth plate member 2 and the surface of the second cloth plate member 2. It only happens.

This step ΔG has such a size that it can be almost neglected in comparison with the conventional step caused by stacking two independent scaffold cloth boards. That is,
According to the present invention, a step can be substantially eliminated.
Therefore, it is possible to realize a highly safe scaffolding device in which a worker walking on the slide-type scaffold cloth board 3 does not trip on a step, and thus can avoid a danger of falling.

Further, according to the present invention, the work of laying the scaffolding slab is significantly simplified since the work of tying the track is unnecessary.

Further, according to the present invention, it is not necessary to use a metal cover for eliminating a step, so that an operator does not slip on the foot, and therefore a highly secure scaffold capable of avoiding the danger of falling. The device can be realized.

The advantages of the sliding scaffold cloth board 3 according to the present invention described above become more apparent when compared with the conventional scaffolds shown in FIGS. For example, in the middle of a scaffold,
In the case where a building material space portion that does not correspond to the standard size of the scaffolding slab occurs, conventionally, as shown in FIG. They were arranged to overlap. As a result, the two scaffold cloth plates 61, 6
Step G1 occurred between the two.

For example, as a specific example of the fixed-length scaffold cloth plate 62, assuming that a plate having typical dimensions and shape is used, the side plate 621 has a thickness g1 of about 5 cm, and the hook 628 It protrudes from the surface of the tread plate 620 at a height g2 of about 2 cm. Also in the fixed-size scaffold cloth board 61, the hook 618 protrudes at the height g3. Step G1 is scaffold cloth board 61
Since the height is based on the tread plate 610, G1 =
g1 + g2 + g3. Therefore, the actual step G1
Is about 9cm. A scaffolding device using a conventional scaffold cloth board,
The worker walking on the scaffold cloth plates 61, 62 is provided with the step G1.
There was a risk of stumbling and causing a crash.

Further, in the corner portion of the scaffold, when a building material interval portion that does not correspond to the fixed-size dimension of the scaffolding slab occurs, FIG.
As shown in FIG. 7 and FIG. 28, a step was generated between the fixed-length scaffold cloth plates 61 and 62 extending from two different directions.

As shown in FIG. 27, when the side plate 623 of the fixed-length scaffolding cloth plate 62 is disposed so as to overlap with the hook 618 of the fixed-length scaffolding cloth plate 61, the same as in the case of FIG.
A step G1 of about 9 cm is generated between 1 and 62.

As shown in FIG. 28, when the side plates 623 of the fixed-length scaffolding cloth plate 62 are arranged so as not to overlap with the hooks 618 of the fixed-length scaffolding cloth plate 61, a step between the scaffolding cloth plates 61, 62 is formed. Is reduced by the height g <b> 3, but the hook 618 of the scaffolding cloth plate 61 protrudes from the side plate 621 in the width direction of the scaffolding cloth plate 62. The protrusion of the hook 618 impairs the aesthetic appearance of the scaffold and damages the sheet or mesh sheet.

Recently, as shown in FIG. 29, there is also known a technique of covering the step portion with the metal cover 7 to eliminate the step G1. However, when the surface of the metal cover 7 is slippery due to rainfall, snowfall, frost, or the like, the worker may slip on his / her feet, and there is still a risk of causing a crash.

According to the present invention, as is clear from the above description, the problems of the prior art can be solved.

Referring to FIGS. 1 to 7 again, another operation and effect of the sliding scaffold 3 will be described.

As described above, the first cloth plate member 1 is
Including a first side plate 121 and a second side plate 122,
The first side plate 121 and the second side plate 122 are arranged below the first tread plate 11 and reinforce the mechanical strength of the first tread plate 11.

The first cloth board member 1 includes a storage space 13, and the storage space 13 includes the first tread plate 11 and the first tread plate 11.
Are surrounded by the side plate 121 and the second side plate 122. As described above, the first cloth plate member 1 is composed of a small number of members, and the storage space 13 is formed on the lower side. Therefore, the weight of the first cloth plate member 1 can be reduced.

The second cloth plate member 2 includes side plates 221 and 222.
And the side plates 221 and 222 are provided on the second tread plate 21.
, On both sides in the width direction W, facing each other. As described above, the second cloth plate member 2 is composed of a small number of members, and moreover, the second tread plate 21
A space is formed underneath. Therefore, the weight of the second cloth plate member 2 can be reduced. For this reason, the slide-type scaffold cloth board 3 becomes light as a whole, and the burden on the worker during transportation can be reduced.

Moreover, since the lower side of the first tread plate 11 is open and the lower side of the second tread plate 21 is open, the latching device 18, the retaining mechanism 23, or the fixing means 16 ( (See FIG. 6).

The guide portions 141 and 142 include a first guide portion 141 and a second guide portion 142. The first guide portion 141 and the second guide portion 142
3, they are arranged on both sides in the width direction W with an interval D therebetween and extend in the length direction L. The second cloth plate member 2 is configured such that the side plates 221 and 222 have the first guide portions 14.
It is supported by the first and second guide portions 142 and guided in the length direction L. According to this structure, the sliding contact area between the first cloth plate member 1 and the second cloth plate member 2 has a small area corresponding to the width and length of the side plates 221 and 222. Therefore, the first cloth plate member 1 and the second cloth plate member 2
