Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary roof, and more particularly to an openable / closable temporary roof which is provided in a civil engineering or construction site and does not use a frame dedicated to the temporary roof.

[0002]

2. Description of the Related Art Conventionally, an openable and closable temporary roof has been provided in civil engineering and construction sites to improve work efficiency regardless of the weather. As a conventional opening / closing type temporary roof, there has been one using a frame newly provided separately from the scaffolding, and one using a gear rail as a traveling rail.

[0003]

However, the above-mentioned conventional temporary roof has the following problems. That is, since the geared motor is used as the opening / closing means, the sectional area of each member such as the traveling rail becomes large and heavy. Further, since the temporary roof is supported by the steel columns, another dedicated frame is required for lifting and opening and closing.

Further, since the exclusive frame is used, the position and area of the opening for carrying in the material may be limited.

An object of the present invention relates to a retractable temporary roof,
The purpose is to reduce the weight and to set the opening at an arbitrary position without requiring a dedicated frame.

[0006]

[Means for Solving the Problems] The above-mentioned problem is an openable and closable temporary roof provided at a civil engineering or construction site, and a traveling rail 2 installed on the top of an outer frame scaffold 1, and the traveling rail 2 The invention according to claim 1, which is a temporary roof characterized by comprising a truss member (3) having a tent (4) stretched thereon, and a tent (4) being stretched, and an opening / closing means (5) for opening and closing the truss member (3), The traveling rail 2 is installed on the top of the frame scaffold 1, the wheels 9 are placed on the traveling rail 2, the truss member 3 is lifted, the wheels 9 on the traveling rail 2 are fixed, the tent 4 is stretched, and the tension is transmitted. The invention is a method for assembling a temporary roof, characterized in that the means 19 is wound around the opening / closing means 5 and is connected to the truss member 3 via the rotating means 20, 22, which is solved by the invention according to claim 10.

[0007]

Therefore, according to the structure of the present invention, since the electric winch is used as the opening / closing means 5, the wire 19 is wound to open / close the truss member 3, so that the traveling rail 2
Can be formed by facing lightweight channel steels to reduce the weight, and the truss member 3 that constitutes the temporary roof can be attached to the outer frame scaffold 1
Since it is directly installed in the housing, a dedicated frame is not required for lifting and opening / closing operations, and since the temporary roof can be opened and closed as a single unit, the opening can be set at any position.

The outer frame scaffold 1 is made of steel frame,
A traveling rail 2 is installed on the top thereof. The truss 3 member is formed of a steel pipe, and a tent 4 is stretched on the member. The truss 3 member is approximately 11 m when it is opened along the traveling rail 2 (FIG. 3), and almost when it is closed (FIG. 4). 5m
When viewed from the front (Fig. 5), it has a triangular shape.

The traveling rail 2 is made of lightweight channel steel, and as shown in FIG. 8, is composed of two portions 11 having a U-shaped cross section, and the inside of the truss member 3 is formed. The wheels 9, 9 attached to the lower string 6 are adapted to run. As shown in FIG. 16, the traveling rail 2 includes a first rail 2A that is vertically connected and a second rail 2A.
It is composed of a rail 2B and a third rail 2C.

The dimension (mm) of the first rail 2A is shown in FIG.
In addition, the dimensions (mm) of the second rail 2B and the third rail 2C are as shown in FIG. 13, and the traveling rail 2 composed of these is as shown in FIG.
With the four types of pressure plate 12 of A, B, C and D,
It is fixed to the upper frame 13 of the outer frame scaffold 1.

Each of the pressing plates 12 holds the traveling rail 2, and the A, B, and D types are attached to the upper frame 13 of the outer frame scaffold 1 by U bolts 14 (FIG. 14), and the C type is externally attached by the hooks 15. It is attached to the upper frame 13 of the frame scaffold 1 (FIG. 15).

As shown in FIG. 6, wheels 9 are attached to the lower chords 6 of the truss 3 member through fixing fittings 7. The fixing metal fitting 7 is attached to the lower chord 6 of the truss member 3 by a bolt 16 (FIG. 7), and a supporting plate 8 is fixedly mounted on the fixing metal fitting 7, and the supporting plate 8 has a wheel 9 mounted thereon. It is attached so that it can rotate.

The relationship among the wheel 9, the support plate 8 and the fixing member 7 is as shown in FIGS. That is, the wheels 9 stored in the traveling rail 2 and traveling (FIG. 9) rotate around the axle 17 fixed to the support plate 8 by the bolts 10,
The support plate 8 is fixed to the fixture 7 by welding or the like.

An opening / closing means 5 is provided just below the traveling rail 2.
An electric winch is attached. The electric winch 5 has a motor 5A, and the motor 5A is received by a rail mount 5B via a winch mount 21. The rail mount 5B is fixed to the pressing plate 12 of the traveling rail 2 with bolts 18. Has been done.

The winch mount 21 is supported by the frame 3A of the truss member 3, and the pulley 23 connected to the motor 5 is rotatably mounted immediately below the frame 3A. A wire 19 is wound around the pulley 23, and the wire 19 passes through a sheave 20 rotatably attached to the traveling rail 2 and a sheave 22 shown in FIG. It is connected to the rear end.

The operation of the present invention having the above structure will be described below.
This will be described with reference to FIGS. 10, 11, 16, 17, 17, 18, 19, 21, and 22. First, Fig. 1
As shown in FIG. 6, the wheels 9 are placed on the traveling rails 2 installed on the tops of the outer frame scaffolds 1, and the truss members 3 are grounded with steel frames (FIG. 17). Each frame of the truss member 3 is lifted by the wrecker 30 onto the outer frame scaffold 1 to fix the wheels 9 (FIG. 18).

Next, as shown in FIG. 19, the truss member 3
Tent 4 is attached to the truss member 3
After shrinking (Fig. 20), by reinforcing the single pipe 32, the 3 ton suspension chain block 31
The truss member 3 is lifted up to the third stage of the outer frame scaffold 1 (FIG. 21).

Further, the single pipe 32 is removed (see FIG. 2).
2), a wire 19 is wound around the electric winch serving as the opening / closing means 5 and passed through the sheeps 22 at both ends of the outer frame scaffold 1,
As shown, the truss member 3 is connected to the front end and the rear end. After that, when the motor 5A is rotated, the truss member 3 is pulled back and forth by the tension of the wire 19, so that the truss member 3 moves along the traveling rail 2 to open.

When closing, the motor 5 is rotated in the reverse direction.

[0021]

As described above, according to the present invention, it is possible to reduce the weight of the opening / closing type temporary roof, and it is possible to set the opening portion at an arbitrary position without requiring a dedicated frame. It was supposed to play. In addition, construction work became possible even in the rain or snow (the amount of snow covered was 30 cm or less).

Further, since it covers the entire construction site, by using it together with the sheet of the external framework scaffolding, it becomes easier to carry out heat retention curing after placing concrete, which is useful for improving the quality of concrete. It can be lifted up by a tow truck or manually operated by a winch, and it is as light and easy as possible, and the cost is extremely low.

If the tent is of a fastener type, it can be easily attached to the truss member. Since it can be opened and closed at any position, it does not interfere with material lifting work. Since it can be installed immediately after pile driving and excavation work and can be used from the time of underground construction, the overall construction period can be shortened.
