Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a scaffolding device that is fixed to a pillar and used at a construction site or the like.

(Prior Art) Scaffolding equipment as shown in FIG. 2 has been in existence for some time. This allows the substrate 4 on which the support beam insertion portion 3 is formed to be fixed to the vertical pillar P by sandwiching the opposing surface of the vertical pillar P located between the fixed side plate 1 and the vertical jacking device 2 with the vertical jacking device 2. When used, multiple items are used in pairs.

Support beams 5 are appropriately inserted into the support beam insertion portion 3, and scaffolding boards 6 are constructed and secured between the support beams 5.

(Problems to be Solved by the Invention) However, the above-mentioned scaffolding equipment has the drawback that it easily comes off from the pillar P, and also has the drawback that it cannot be easily handled when a scaffold is required for only one pillar P.

In order to solve this problem, the purpose of the present invention is to provide a scaffolding device that can be fixed to a standing pillar in a manner that does not easily come off, and that can easily provide a stable footing even for a single standing pillar. shall be.

(Means for Solving the Problems) In order to achieve the above object, the present invention, as shown in FIG. , the member 1
2 is provided with connecting members 14, 14 that extend through the vicinity of each side of the pillar P and reach the other surface P2 side of the pillar P opposite to the one surface P1, and the connecting members 14, 1
A jacking device 15 for pressing the other surface P2 is installed between the distal ends of the scaffolding frame 10 so that the distal ends thereof can be opened and closed. A U-shaped piece 24 is disposed to be fitted with the lateral movement restricted, and the U-shaped piece 24 and the scaffolding frame 10 are fixedly connected by a support member 27.

(Function) When using the device of the present invention, first, the jacking device 15 is placed in an open state between the ends of the connecting members 14, 14, and in this state, the vertical pole P is placed between the connecting members 14, 14. position. Next, the jacking device 15 is brought into a closed state between the distal ends of the connecting members 14, 14, while the abutment member 12 of the scaffolding frame 10 is brought into contact with one surface P1 of the upright pillar P, and the U-shaped piece 24 is also brought into contact with the upright pillar. It is fitted onto one surface P1 of P. In this state, the jacking device 15 is operated to press the other surface P2 of the upright column.

As a result, the contact member 12, the connecting members 14, 1
4 and the jacking device 15 surround and tighten the vertical pillar P, and thus the device of the present invention is firmly fixed to the vertical pillar P and becomes difficult to come off from the vertical pillar P.

In addition, the device of the present invention controls the inclination displacement of the U-shaped piece 2
4 and the support member 27, the movement becomes even more stable.

(Example) Hereinafter, specific examples of the present invention will be described based on illustrative drawings.

FIG. 1 is an overall perspective view of the device of the present invention. The scaffolding frame 10 has a structure in which expanded metal 11a is stretched over the upper surface of a rectangular frame 11, and a contact member 12 that contacts one surface P1 of a vertical column P is provided on one side. The contact member 12 has an elastic plate 13 attached to its contact surface.

The contact member 12 is provided with connecting members 14, 14, which extend through the vicinity of each side of the upright pillar P and reach the other surface P2 of the upright pillar P, which is opposite to the one surface P1. The connecting member 14 of this example has enlarged portions 14a at both ends.
The rod-shaped body is inserted into the through hole 12a of the abutting member 12 in a freely movable manner and in a state in which coming out is restricted.

A vertical pillar P is provided between the leading ends of the connecting members 14, 14.
A jacking device 15 for pressing the other surface P2 is installed. This jacking device 15 includes a construction plate 16 and a nut 17 fixed to the construction plate 16.
an operating screw rod 18 screwed into the screw rod 1;
8 and a press plate 19 pressed by the tip.
An enlarged portion 1 is provided at one end of the construction plate 16 and the push plate 19.
Through holes 20 and 21 having a smaller diameter than 4a are provided, and one connecting member 14 is freely inserted into these through holes 20 and 21. In addition, the other connecting member 1 is attached to each other end of the construction plate 16 and the push plate 19.
Engagement grooves 16a and 19a, which are narrower in width than the diameter of the enlarged portion 14a, are formed to engage with the enlarged portion 14a. Therefore, by rotating the construction plate 16 and the push plate 19 around one of the connecting members 14, it becomes possible to open or close the distal ends of the connecting members 14, 14.
Furthermore, by screwing in the operating screw rod 18 in the closed state, it becomes possible to displace the push plate 19 toward the other surface P2 of the vertical column P. Note that 22 and 23 are elastic members.

Reference numeral 24 denotes a U-shaped piece having elastic plates 25, 26, . This U-shaped piece 24 and the scaffolding frame 10 are fixedly connected by a support member 27. The support member 27 consists of a vertical member 28 and a diagonal member 29, the latter 29 effectively preventing the free end of the scaffolding frame 10 from being displaced downwardly.

The use of the apparatus of the above embodiment is as follows. First, the jacking device 15 is displaced in order to open the distal ends of the connecting members 14, 14. That is, the construction plate 16 and the push plate 19 are rotated upward about one of the connecting members 14.
In this state, the standing post P is positioned between the connecting members 14, 14, and the contact member 12 of the scaffolding frame 10 is brought into contact with one side P1 of the standing post P, and the U-shaped piece 24 is also placed on one side P1 of the standing post P. so that they fit together.

Next, the jacking device 15 is displaced so that the distal ends of the connecting members 14, 14 are brought into a closed state. That is, by rotating the construction plate 16 and the push plate 19 around one of the connecting members 14, each engagement groove 16
a, 19a are engaged with the other connecting member 14.

Thereafter, the operating screw rod 18 is screwed in and operated. When the operating screw rod 18 is screwed in a certain amount,
The construction plate 16 is the enlarged portion 14a of the connecting members 14, 14.
...and the displacement is regulated. This construction board 1
The operating screw rod 18 supported by 6 displaces the push plate 19 toward the other surface P2 of the vertical column P.
This push plate 19 finally reaches a state where it strongly presses the other surface P2 of the upright pillar P, and the device is fixed.

In this way, a scaffold can be simply and easily formed even for a single pillar P.

The worker then performs the work while riding on the scaffolding frame 10 of the device thus fixed.

Furthermore, by attaching the devices of the present invention to a plurality of standing pillars P that are close to each other, scaffold boards can be erected and fixed to the scaffold frames 10 of each device, and a wide scaffold can be easily formed.

(Effect of the invention) As is clear from the above, in the present invention, when the device is installed, the contact member 12, the connecting members 14, 1
4 and the jacking device 15 tighten the vertical pole P in a manner that surrounds it, and the U-shaped member 24 and the support member 27 prevent the entire device from tilting. The scaffolding frame 10 is firmly and stably attached in a manner that does not easily come off, and since the scaffolding frame 10 is fixed to the pillar P as a part of the device, stable scaffolding can be easily and easily established even for a single pillar P. It becomes something that is formed.
