Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold plate frame unit which constitutes a scaffold plate frame to be assembled when a scaffold is provided around a pillar of a building under construction.

[0002]

2. Description of the Related Art In constructing various structures,
First, the steel frames are assembled, and then various works are carried out by appropriately providing temporary scaffolds around these steel frames.

The scaffold has been constructed by connecting a large number of straight pipes vertically and horizontally using various clamps.

[0004]

However, according to the above-mentioned prior art, there is a problem that an extremely large number of pipes and clamps are required, and that the mounting work is complicated and the work requires a great deal of labor.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a unit capable of easily forming a frame for a scaffolding plate.

[0006]

In order to solve the above problems, the present invention relates to a scaffolding plate frame unit in which a plurality of adjacent scaffolding plate frame units are arranged side by side so as to surround a standing fixed column. And a scaffolding plate support portion that extends in the horizontal direction in a state in which the connection portions are connected to each other and are attached around the fixed column. It is configured.

[0007]

A plurality of scaffolding board frame units of the present invention are arranged next to each other so as to surround a fixed column (for example, H-shaped steel) standing upright. For example, when the fixed column is H-section steel, four units are arranged at the four corners of the H-section steel, and adjacent units are connected to each other by compatible connecting portions. On the other hand, it is attached and fixed using an appropriate attachment means, for example, a catch clamp or the like.

At this time, since the scaffolding plate supporting portion projecting in the horizontal direction projects around the fixed column to form a scaffolding plate supporting frame, the scaffolding plate is placed and fixed there.

As described above, according to the scaffolding board frame unit of the present invention, the scaffolding board frame can be formed more easily and more reliably than in the prior art in which linear pipes are combined and connected by various clamps. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing a scaffolding plate frame unit according to an embodiment of the present invention, and FIG. 2 is a perspective view thereof.

The scaffolding board frame unit 1 of this embodiment is a rod body,
Specifically, it is configured by fixing metal pipes in an orthogonal state. The metal pipe is used in consideration of various requirements such as toughness of the unit 1, weight reduction of the unit 1, convenience of handling, and the like.

In the embodiment shown in the drawings, first, a first pipe 4 is prepared whose one end side is a connection receiving portion 3 which is compatible with a connection projection 2 which will be described later. Then, at a position closer to the connection receiving portion 3 side than the central portion of the tubular body of the first pipe 4, the second and third pipes 5 are sandwiched so as to sandwich the first pipe 4 in an orthogonal state, 6 are fixed in a straight line. That is,
Arc-shaped recesses conforming to the peripheral surface shape of the first pipe 4 are formed at the ends 5a, 6a of the second and third pipes 5, 6, respectively. The pipe 4 is tightly adhered to the peripheral surface of the tubular body and is firmly fixed by an appropriate means such as welding.

A connecting projection 2 is formed by partially inserting a connecting pipe 7 having a diameter compatible with the inner diameter of the second pipe 5 into the open end 5b of the second pipe 5 and fixing it by welding or the like. ing. The connection pipe 7 is also compatible with the first pipe 4, and a plurality of units are connected side by side by fitting the connection protrusion 2 of a unit into the connection receiving portion 3 of an adjacent unit.

In the figure, 8 is a pin hole provided in the connection receiving portion 3,
Reference numeral 9 denotes a pin hole formed on the cylindrical body of the connecting projection 7 so as to be aligned in the axial direction, and 10 denotes a fixing pin.
By inserting the fixing pin 10 by aligning the pin holes 8 and 9 with each other after the connection projection 2 is fitted in the connection projection 2, the connection projection 2 is prevented from coming out of the connection receiving portion 3, and the connection reception of the connection projection 2 is prevented. By changing the amount of insertion into the portion 3, it becomes possible to accommodate fixed columns 11 of various sizes. However, a female screw may be provided in the connection receiving portion 3 instead of the pin hole 8, and a bolt adapted to the female screw may be used instead of the fixing pin 10 to fix the both.

It should be noted that the entire length of the first pipe 4 and the end of the connecting pipe 7 from the outer end portion 6b of the third pipe.
Up to the same length.

A scaffolding board frame unit 1 having the above structure
3 to 6, they are connected side by side so as to surround the circumference of a fixed column 11 such as an H-shaped steel that is erected in advance, and are attached to the fixed column 11.

That is, the unit 1 is arranged at the four corners of the fixed column 11 so that the connecting projection 2 and the connecting receiving portion 3 are adjacent to each other.
Is fitted into the connection receiving portion 3 and fixed by the fixing pin 10 or the like. Then, as shown in FIGS. 5 and 6, it is attached and fixed to the fixed column 11 by using an appropriate attaching means such as a catch clamp 12.

As a result, the first pipe 4 and the third pipe 6 constituting each unit 1 are horizontally projected around the fixed column 11, and the scaffolding plate is formed by these overhanging pipes. A scaffolding board support frame that supports 13 is formed. Therefore, as shown in FIG. 7, if the scaffold plate 13 is installed and fixed on the projecting pipe, the scaffold can be easily and surely built around the fixed column 11. Further, according to the embodiment shown in the drawings, since the insertion amount of the connecting projection 2 with respect to the connecting receiving portion 3 can be freely adjusted and fixed, there is an advantage that it can be applied to fixed columns of various sizes.

In the figure, reference numeral 14 connects the first pipe 4 and the third pipe 6 in each unit 1 and constitutes a scaffolding plate support frame like the first and third pipes 4 and 6. It also serves as a transfer pipe, and at the same time acts as a brace that reinforces each unit 1. The transfer pipe 14 does not have to be the linear one shown in the drawing, and may be formed in a curved shape from the end of the first pipe 4 to the end of the third pipe. Good.

In each unit 1, a handrail pillar support pipe 15 is vertically fixed to the outer ends 4b and 6b of the first and third pipes 4 and 6 by welding or the like. . A handrail post 16 is inserted into the handrail post support pipe 15 so that its height can be adjusted.

That is, the handrail pillars 16 are provided with pin holes 17 arranged in parallel in the vertical direction at appropriate intervals, while the handrail pillar support pipe 15 has a chain for preventing loss at the upper end thereof. A fixing pin 19 is provided via 18.

Then, by adjusting the insertion amount of the handrail post 16 into the handrail post support pipe 15 and inserting the fixing pin 18 into an appropriate pin hole 17, the handrail post 16 is brought to a desired height. Is set.

A handrail rod holding portion 21 for inserting the handrail rod 20 is provided at the upper end of the handrail pillar 16, and the handrail rod 20 is passed through here to connect the handrail rods 20 to the corner joint 2.
If the two are connected, a handrail with a desired height is formed around the scaffolding plate 13.

[0025]

According to the present invention, it is possible to construct a frame for a scaffolding plate around a fixed column very easily and surely, and since units having the same structure are used in combination, it is manufactured. There are effects such as cost reduction.
