Description

[Detailed description of the invention] (Industrial application field) This invention relates to a suspended scaffolding mainly used in the construction of wooden houses such as ordinary houses.

(Prior Art) Normally, scaffolding for two-story general houses, etc., was completely enclosed around the outside, but recently, to shorten the construction period, panels produced in factories are used. Furthermore, in the case of relatively low scaffolding for ordinary houses, etc., two sets of stepladders, which serve both as supports and for lifting and lowering, are erected at appropriate intervals, and a scaffold board made of plywood or the like is simply placed between the upper ends of each stepladder.

(Problem that the invention aims to solve) However, the former method requires less work at the construction site, less use of scaffolding, and low-risk construction except for the second floor, which is a high-risk area such as general housing. There is no longer a need to enclose the outer periphery of floors, etc. In addition, in the latter case, if each stepladder and the scaffolding board are not completely connected and the ground is sloped or weak, the scaffolding board may become unstable and easily fall over, which is very dangerous. Moreover, the level of the scaffolding boards could not be secured, making the work extremely difficult.

Therefore, this idea was devised in view of the above-mentioned issues. Complete scaffolding is installed only on the second floor, which is a high-risk part of a general residence, etc., and the first floor, etc., which is a low-risk part, is equipped with a complete scaffold. In addition to making it possible to move the scaffolding to any desired location, it is not limited by the flatness of the ground or the strength of the ground.
The scaffolding board is stable and safe with no risk of falling, the level of the scaffolding board can be ensured, making work extremely easy, and it is economical because there is no need for lifting equipment to reach the scaffolding board. Furthermore, the present invention provides a suspended scaffolding that does not pose any hindrance to the final ground leveling work or the transportation of materials for interior construction work.

(Means for Solving the Problems) In order to achieve the above-mentioned purpose, this invention has a scaffold board holder installed between the lower ends of the front support and the rear support, and the upper end of the rear support. A plurality of fixing frames are formed with hanging screws attached to each eaves edge of a general house at the upper end of the rear support and the rear bracket tip, and the lower ends of one of the supports of each fixed frame are mutually connected. A fixed scaffold is constructed by connecting the frames at appropriate intervals with connecting rods, and installing scaffold plates between the scaffold plate holders of each fixed frame, and one rear support of the ladder body having a hook at the upper end. A scaffolding plate holder is constructed between the vertically substantially central portions of the ladder body and the front support, and a pair of moving frames are formed with an abutting plate for abutting the foundation concrete attached to the rear side of the lower end of the ladder body, A movable scaffold is constructed by installing scaffold plates between the scaffold plate holders of each movable frame, and is movably suspended by hooking the hooks of the movable scaffold to the connecting rods of the fixed scaffold.

(Example) Hereinafter, an example of this invention will be described based on the drawings.

As shown in Figure 1, the suspended scaffold of this invention consists of a fixed scaffold 1 that is suspended from the eaves of a general house A, and a movable scaffold 2 that is movably suspended from the fixed scaffold 1. ing.

The fixed scaffold 1 has a net support 5 installed between the vertical center of the front support 3 and the upper end of the rear support 4, which is shorter than the front support 3, and the front support 3 and the rear support. A scaffold board holder 6 is installed between the lower ends of the rear support 4 and the upper end of the rear support 4 and the rear support 4.
A suspension screw 9 with a tightening plate 8 is rotatably attached upward to the tip of the bracket 7 that protrudes from the rear side of the upper end, and a clamp 1 is attached to the lower end of the rear column 4.
A plurality of fixing frames 11 are formed by attaching 0 to A net 13 for fall prevention is continuously installed between the upper sides of the pillars 3 and between the net supports 5, and a scaffold board 14 is installed between the scaffold board supports 6 of each fixed frame 11. ing.

On the other hand, the movable scaffold 2 has two rear supports 16 each having a hook 15 at the upper end, and a footrest rod 1 between them.
A ladder body 18 is provided in which the ladder bodies 18 are horizontally hung at appropriate intervals, and one rear column 16 of this ladder body 18 and a front column 19 projecting forward from the one rear column 16.
A scaffold board support 20 is installed between the vertically central portions of the ladder body 18, and an abutting plate 2 for abutting the foundation concrete C is installed at the rear of the lower end of each rear support 16 of the ladder body 18.
A pair of moving frames 23 are formed by protruding 1 from each other through two support rods 22, and further, a scaffold board 24 is constructed between the scaffold board supports 20 of each moving frame 23, and Two braces 25 for stabilization are installed in an intersecting manner approximately in the vertical center of the front support 19 of each moving frame 23 and at the lower end of the front support 19 of each moving frame 23. ing.

Then, the hook 15 of the movable scaffold 2 is hooked onto the connecting rod 12 of the fixed scaffold 1, so that it is movably suspended.

(Effects of the invention) Since this invention is configured as described above, when in use, as shown in Figure 2, protrusions are provided at appropriate intervals on each eave edge B, etc. under the eaves of a general house A. 2
Fix a hanging fitting E such as a nut to the upper end of each hanging hole D, and insert each fixing frame 11 of the fixed scaffold 1 of this invention into the hanging fitting E, and insert the hanging screw 9 from the hanging hole D. Not only can it be hung from the edge of each eave B of a general house A, but also the hook 15 of the movable scaffold 2 of the fixed scaffold 1 can be hung with an extremely easy operation of just tightening with the rotation means of the tightening board 8. By hanging the scaffolding so that it can be moved freely, the complete fixed scaffolding 1 can be installed only on the second floor, etc., which has a high degree of danger, such as general housing A, and can be installed on the first floor, which has a low degree of danger. Therefore, the movable scaffold 2 can be moved to any desired location.

Moreover, since the movable frame 23 of the movable scaffold 2 is not in contact with the ground due to the hanging type, the scaffold boards 14, 20 are not restricted by the flatness of the ground, the strength of the ground, etc. Each fixed frame 1 of the scaffold 1 is stable and safe with no risk of falling, and is fixed to the eaves edge B, which is the reference surface of the general house A.
1 is suspended, the level of the scaffolding boards 14 and 20 can be secured, making the work extremely easy.In addition, the final leveling work, bringing in materials for interior construction work, and access to the first floor of general housing A, etc. There is no problem in working with the parts.

Furthermore, by providing the ladder body 18 on the moving frame 23 of the moving scaffold 2, there is no need for lifting equipment such as a stepladder or a ladder, which is extremely economical.

In addition, the rear support 4 of the fixed frame 11 of the fixed scaffold 1
A bracket 7 for hanging to the eaves edge B etc. is provided protruding from the rear side of the upper end, and the movable frame 23 of the movable scaffold 2
Foundation concrete C on the rear side of the lower end of the ladder body 18.
By protruding the abutting plate 21, the fixed frame 11 of the fixed scaffold 1 and the movable frame 2 of the movable scaffold 2
Fixed scaffolding 1
And the vertical state of the moving scaffold 2 can be maintained reliably.

As explained above, according to this invention, complete fixed scaffolding can be installed only on the second floor, which is a high risk area such as in a general residence, and a movable scaffold can be installed on the first floor, which is a low risk area. In addition to being able to move to any desired location, the scaffolding board is stable and safe without the risk of falling, without being constrained by conditions such as the flatness of the ground or the strength of the ground, and the level of the scaffolding board is It is very easy to secure and work, and it is economical as there is no need for lifting equipment to reach the scaffolding board.Furthermore, there is no problem in carrying in materials for the final leveling work or interior construction work, and there is no need for fixed scaffolding or Various effects such as ensuring the vertical state of the moving scaffolding can be obtained.
