DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind curing device provided near a welding point to prevent the influence of wind when welding a building such as a steel structure at a construction site.

[0002]

2. Description of the Related Art When constructing a building such as a steel frame structure, steel members are assembled at a construction site and seams of the members are connected by welding, and the welded portions are exposed to strong wind. In addition, since the welding strength is reduced, the surroundings of the welding location are cured to prevent a strong wind. This curing is performed, for example, by assembling a short pipe with a clamp to form a frame, arranging the frame around a welded portion, fixing the frame to a steel frame material, and stretching a flameproof sheet over the frame.

[0003]

In the conventional curing method, materials such as a single pipe and a clamp are unloaded to a welding point and assembled on a steel beam or the like. This is time-consuming and has safety issues, and also hinders the working path during installation of the curing. Further, the setting work and the welding work of the curing are different occupations, and it is necessary to separately arrange a craftsman.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the problem is that the assembling and installation are easy, so that the curing installation work and the welding work can be performed by the same craftsman. It is an object of the present invention to provide an air conditioner that can reduce labor costs.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided an apparatus which is disposed near a welding position of a steel frame material at a construction site to prevent the influence of wind at the time of welding work. When,
An inner frame and an outer frame to which different ends of the film material are detachably attached, a connecting member connecting the inner frame and the outer frame, and fixing means for detachably fixing the connecting material to a steel frame material Wherein the outer frame is formed to have a larger outer shape than the inner frame, and is provided on the connecting member so as to be rotatable outside the inner frame. .

In the climate curing device of the present invention, a locking portion for locking the steel frame material is provided on the outer frame, and the locking portion can be formed to be rotatable. Further, in the present invention, the fixing means comprises a first fixing tool detachably fixed to the connecting member, and a second fixing tool detachably fixed to the steel frame material, and the first fixing tool It may be formed by connecting the second fixture with the second fixture so as to be rotatable mutually. In the fixing means thus formed, if the first fixing tool and the second fixing tool are appropriately rotated, the fixing angle of the connecting member with respect to the steel frame material, that is, the fixing angle of the film material, according to the wind direction Can be adjusted appropriately, and welding work can be performed regardless of the wind direction.

FIG. 1 is a side view of a wind curing device according to one embodiment of the present invention. FIG. 2 is a front view of an air conditioner according to an embodiment of the present invention. For convenience of illustration, the film material 15 is omitted.
The inner frame 12 and the outer frame 11 are shown in an upright state. FIG. 3 is a plan view of the air conditioner according to one embodiment of the present invention, and the plan view when the tube 13 is rotated in the horizontal direction is also shown by dotted lines. As described above, in FIGS. 1 to 3, the wind curing device 10 includes a tube 13 as a connecting member, a clamp 17 for detachably fixing the tube 13 to the steel beam 20, and a shaft member such as a reinforcing bar. It comprises a frame 12 and an outer frame 11, and a film material 15 stretched between the inner frame 12 and the outer frame 11.

Here, the inner frame 12 is formed in a U shape by a shaft material, and its ends 12c, 12c are fixed to both ends 13a of the tube 13 by welding or the like. As shown in FIG. 2, the outer frame 11 is formed in a rectangular shape larger than the inner frame 12 by the shaft member, and a shaft member 11c on one side thereof is inserted into the inside of the tube 13, and the outer frame 11 is In a state where the membrane material 15 is stretched between the inner frame 12 and the inner frame 12 around the shaft 11c.
Is formed so as to be rotatable outside.

The clamp 17 has a steel frame fixing portion 17b which is detachably fixed to a steel frame material such as a steel beam 20, and the like.
It comprises a tube fixing portion 17a which is detachably fixed to the tube 13, and the steel frame fixing portion 17b and the tube fixing portion 17a are rotatably connected to each other. With this rotatable connection structure, for example, one of the steel frame fixing portions 17b in FIG. 2 is released, and the pipe 13 is rotated as shown by a dotted line M in FIG. When the portion 17b is fixed, the entire air conditioning device 10 can be rotated and moved in the horizontal direction. Therefore, depending on the wind direction,
If the fixing angle of the wind curing device 10 is appropriately adjusted, the welding operation can be performed regardless of the wind direction.

FIG. 4 is a side view of an embodiment different from that of FIG. 1 and shows how the outer frame 21 is arranged on both sides of the inner frame 12 by solid lines and dotted lines, and FIG. FIG. 2 is a plan view of an outer frame 21 and a tube 13 used in the present embodiment. In FIG. 5, the outer frame 21 is formed of a shaft material such as a reinforcing bar so that the entire shape is substantially convex, and the shaft material 21c inserted into the tube 13 is a shaft material 2c.
1b and 21b are integrally formed so as to be continuous with each other.
The locking portion 21a is formed of a shaft member separated from the shaft members 21b, 21b, and is rotatably connected to the shaft member 21b by a joint 22. This joint 22 is
1a and the shaft member 21b are restrained so as not to come off. Wind curing device 10 including outer frame 21 having the above configuration
In this case, as shown in FIG. 4, regardless of which side of the outer frame 21 is disposed on the inner frame 12, the locking portion 21 a rotates around the joint 22 and locks on the upper flange of the steel beam 20. It is configured as follows.

In any of the air curing devices 10 shown in FIGS. 1 and 4, when the device is used, the inner frame 12 is preferably used.
The tube 13 is fixed by the clamp 17 so that the inner frame 1 is substantially vertical.
It is installed so as to abut or lock on the steel beam 20 on the windward side of the second. When the wind curing device 10 is installed on the windward side of the welding location 20a as described above, the worker 25 performs the welding operation on the leeward side while blocking the wind with the film material 15.

[0012]

According to the weather curing device of the present invention, the outer frame is formed to have a larger outer shape than the inner frame, and is provided on the connecting member so as to be rotatable on the outer side of the inner frame. If the outer frame is rotated so as to be located on the windward side, the wind is blocked by the film material stretched between the outer frame and the inner frame, and the welding operation can be performed even in a strong wind.

In the weather curing device of the present invention, the locking portion for locking to the steel frame material is provided on the outer frame and the locking portion is formed to be rotatable, so that the locking portion is locked to the steel frame material. This can prevent the film material from being blown off together with the outer frame by wind pressure. Further, since the locking portion is rotatably provided, it becomes easy to lock the locking portion to the steel frame material regardless of which side of the outer frame is located on the inner frame.
