Description

[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention relates to a windshield device used at a welding work site such as an internal pillar of a building construction. It is easy to carry and handle, and it is easy to assemble, disassemble, transport, store, etc. The feature is that welding work can be performed efficiently without the need.

[0002]

2. Description of the Related Art Conventionally, gas welding work for steel inner columns has been carried out at work sites such as building construction.

However, particularly in a high place of a building, it is difficult to perform efficient welding work because of strong wind.

Therefore, it is necessary to protect the welding work site from the wind.

Conventionally, when performing the welding work of the inner column in the high place of the building, a receiving piece for providing a windshield panel is welded in advance near the welding point, and the inner column to be connected is an erection piece. After temporarily fixing with a cross beam or the like, a windshield panel was provided around the inner column using the receiving piece to form a windshield device.

[0006]

The conventional windshield device for protecting the welded portion from the wind requires the welding of the receiving piece in the vicinity of the welded portion in advance, which is troublesome. It took time to install and disassemble the panel.

The present invention has been made in view of the above circumstances. When the welding work is performed at a high place such as a building, the assembly,
It can be installed very easily without disassembling,
An object of the present invention is to provide a windshield device that can perform efficient welding work.

[0008]

In order to solve the above-mentioned problems, the present invention is designed so that it can be foldable and expanded in a generally L-shaped plane.
It is composed by connecting a plurality of windshield panels, each of which has a freely connectable portion with the end of the windshield panel facing the outside edge, and further, an entrance door for workers is provided at an appropriate position of at least one windshield panel. It is configured as follows.

[0009]

The windshield device of the present invention can be folded and easily brought into a welding work site such as an inner pillar of a building construction, and efficient welding work can be carried out without assembling and disassembling it. You can

That is, in the windshield device of the present invention, usually, a plurality of windshield panels folded in two are carried to a welding work site, and then each windshield panel is opened into an L shape at the welding site. All you have to do is connect them in the state of enclosing.

If the above procedure is reversed, it can be easily disassembled for transportation, storage, etc., and can be reused.

Therefore, in the present invention, as in the conventional case,
It is not necessary to weld the receiving piece for providing the windshield panel in the vicinity of the welded portion in advance, and it is possible to easily assemble, disassemble, transport, store, etc., and perform efficient welding work.

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

FIG. 1 shows the windshield device of the present invention for connecting and welding the inner pillars H when building a building.

As shown in the embodiment of the drawings, the windshield device has four windshield panels 1, 2, 3 and 4 each of which is expanded into a substantially L-shape in a plane and is foldable. It is configured to be connected around the circumference of the with a proper interval.

The windshield panels 1, 2, 3, 4 are
Synthetic resin sheets or the like S are adhered to the frame bodies 5 and 6 of a predetermined size, and a freely connectable portion 10 with the windshield panel end portion facing the outer end is formed.

Reference numeral 7 in the drawing denotes an entrance door for an operator or the like to enter and exit, and is provided in at least one windshield panel, in the illustrated embodiment, the windshield panel 4.

Since the four windshield panels 1, 2, 3 and 4 constituting the windshield device have the same structure, one of them will be described in detail.

First, as shown in FIG. 3, the windshield panel 1 is constructed such that one sides 5a and 6a of the frame bodies 5 and 6 are connected by a hinge 8 so that the windshield panel 1 can be expanded and folded.

That is, one end 9a of the folding metal fitting 9 is pinned to an appropriate position above the frame body 6 of the windshield panel 1, and the other end 9b is pinned to an appropriate position above the frame body 6 of the windshield panel 1, Further, the central portion 9c of the folding metal fitting 9 is connected by a pin so that it can be folded.

Therefore, when the two frames 5 and 6 are expanded through the hinges 8, the folding metal fittings 9 are straightened so that the windshield panel 1 is maintained in a substantially L-shaped expanded state. To function.

Further, in the present invention, the windshield panels 1, 2,
Each of the outer end portions of 3 and 4 is formed with a freely connectable portion 10 with the opposite panel end portion.

An example thereof is shown in FIG.

That is, the frame bodies 5 and 6 constituting the windshield panels 1, 2, 3 and 4, respectively, are formed of square pipes, and the horizontal bars 5 provided at the upper and lower intermediate portions of the frame bodies 5 and 6, respectively.
A freely connectable portion 10 is formed between b and 6b.

That is, each windshield panel 1, 2,
One of the outer end portions of 3, 4 specifically, the horizontal crosspiece 6b of the frame body 6
A connecting rod 11 is slidably provided in the inside, and a receiving hole 12 of the connecting rod 11 is provided at the other outer end, specifically, the horizontal rail 5b of the frame body 5.

In the figure, 13 is a knob for sliding the connecting rod 11, 14 is a long hole for restricting the limit of storage and projecting of the connecting rod 11, and 15 is a screw for fixing the connecting rod 11 inserted in the receiving hole. Is.

The connectable portion 10 having the above structure connects the outer end portions of the opposing windshield panels 1 and 2, 2, 3, 3, 4 and 4 and 1, respectively.

That is, the crosspiece 6 of the frame body 6 of the windshield panel 1
The connecting rod 11 in b is inserted into the receiving hole 12 of the horizontal rail 5b of the frame body 5 of the windshield panel 2, and the windshield panels 1 and 2 are connected by the connecting rod 11 by tightening the screw 15. 2 and 3, 3 and 4 and 4 and 1 are sequentially connected.

In the present invention having the above-mentioned structure, each windshield panel 1, 2, 3, 4 is folded and carried to the welding work site prior to use.

After that, when the windshield panels 1, 2, 3 and 4 are respectively opened, the folding metal fitting 9 is linearly extended,
Each of the windshield panels 1, 2, 3, and 4 has a substantially L-shaped plane.

Next, the expanded windshield panels 1, 2,
It suffices to connect and install the parts 3 and 4 to be welded, that is, around the inner pillar H at the center of the floor shown in FIG.

The disassembly, removal, and transfer after welding is completed are as follows.
Conversely, the connection between the windshield panels 1, 2, 3, 4 may be released, and the folding metal fitting 9 and the respective frames 5 and 6 may be folded.

As described above, the windshield device of the present invention does not need to weld the receiving piece for attaching the windshield panel in the vicinity of the welding point as in the conventional case, and the assembly and disassembly of the windshield device is troublesome. It is very easy to handle.

[0034]

EFFECTS OF THE INVENTION According to the present invention, the windshield panel can be easily handled, such as being carried, and the welding work can be performed efficiently without the need for assembly and disassembly.
