Abstract

PURPOSE:To weld quickly and safely a tight frame on the upper face of a beam and to increase the operability by fitting a welding work device to the frame to load a tight frame and a frame and by constituting out of the leg body to enable the adjustment of the gap so as to pinch a tight frame and the wheels for moving of the lower end of the leg body. CONSTITUTION:The right and left leg bodies 12, 13 are adjusted in the width of a tight frame 3 by putting up a welding work device onto a beam 2, also the gap is adjusted until a supporting rod 16 pinches the beam 2 from the right and left. The box which loads numerous tight frames 3 is then fitted into frame 11, 14. The right frame 3 is then welded on the upper face of the beam 2 by making the tight frame inside the leg bodies 12, 13 located by taking out of the box the tight frame 3 with the movement of the whole device on the beam 2. There is no difficulty in moving even if there is a horizontal beam on the beam 2 due to the supporting rod 16 being rocked.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a tight frame welding device used when welding a tight frame to a beam.

<Prior art and its problems> Figure 2 is a perspective view of a roof plate 1 of a folded plate structure attached to beams 2 to form the roof of a factory or the like. In this roof, a rectangular wavy tight frame 3 is welded to the upper surface of a beam 2 of a roof base material made of H steel, and a roof board 1 having a rectangular wavy folded structure is adhered to the tight frame 3. configured.

Here, the tight frame 3 has a predetermined length,
By welding the beams 2 side by side in a state that they are lined up on the upper surface of the beams 2, the beams 2 are connected in the longitudinal direction, and screw punches 4 are respectively erected on the top sides. The roof board 1 is inserted into a mounting hole (not shown), and the roof board 1 is installed by screwing the tightening nut 5 into the screw 4, and the ends of the roof board 1 are overlapped with the adjacent roof board. By doing so, the roof is formed.

When constructing such a roof, when welding the tight frame 3 to the upper surface of the beam 2, conventionally, a worker had to weld a large number of tight frames and carry cap tires, which are electrical cords, while walking on the beam 2 while welding the tight frame 3. was welded to the top surface of beam 2.

When the Tight Frame in his possession ran out, he received another Tight Frame and performed the same work while walking on the beam 2.

Therefore, such work not only requires a great deal of effort on the part of the worker, but also involves the risk of falling. In addition, the welding work is performed by the worker while holding the tight frames together, and there is a limit to the number of tight frames that can be carried, so there are problems in that work efficiency is poor and speed is lacking.

Means for Solving the Problems> The present invention solves the problems of the prior art by providing a new tight frame welding device that runs on a beam while mounting a large number of tight frames. .

That is, the present invention provides a pedestal on which a tight frame is mounted, legs attached to the pedestal such that the interval can be adjusted so as to sandwich the tight frame welded to the upper surface of a beam of a roof base material, and a lower end of the legs. The vehicle is characterized by comprising wheels that are attached to the vehicle and move over the beam.

Function> In the present invention, wheels are transferred over beams to transport a large amount of tight frames. The legs also sandwich a tight frame welded to the top of the beam to prevent it from falling off the beam.

<Embodiment> FIG. 1 shows an embodiment of a tight frame welding device according to the present invention.

This device consists of frames 11, 14, legs 12, 13 and wheels 15. More preferably, it consists of a support rod 16.

The pedestal includes an upper frame 11 constructed in a rectangular shape and legs 12.1.
It consists of a lower frame 14 which extends in the same direction as the longitudinal direction of the upper frame 11 at the middle part of 3, and a tight frame in a free state before welding is mounted within these frames 11 and 14. It has become. That is, a box (not shown) is placed within the upper frame 11.
etc. are fitted into the box, and the bottom surface of the box is supported by the lower frame 14, and the box is mounted by filling a large number of tight frames into the box.

The legs 12 and 13 are U-shaped, and their upper ends are attached to the lower surface of the upper frame 11 of the pedestal. Of these, the left leg 12 is fixed by welding to the lower surface of the upper frame 11, while the right leg 13 is capable of sliding left and right with respect to the upper frame 11. This sliding mechanism is achieved by, for example, forming a long hole in the lower surface of the upper frame 11, and attaching a slider such as a bolt to the leg body 13, which slides inside the long hole.A locking device such as a nut is attached to the slider. , the slide is fixed in an appropriate position. The distance between the legs 12 and 13 is adjusted by sliding the right leg 13, so that the tight frame 3 welded to the upper surface of the beam 2 is sandwiched between the left and right legs 12 and 13. , toppling and falling during running on the beam 2 is prevented. Wheels 15 are rotatably mounted on the lower ends of the legs 12 and 13, respectively, and the entire device runs on the beam 2 by shifting the wheels 15. In this embodiment, the wheels 15 are each leg 12.
, 13, three wheels are attached to each of the front and rear ends and the middle part, but the wheels in the middle part may be omitted.

The support frames 16 are attached to the side surfaces of the left and right legs 12 and 13 in pairs. That is, brackets 17 are suspended from the left and right sides of the upper frame 11, and horizontal adjustment rods 18 are attached to the brackets 17 to adjust the left and right legs 12, 13.
The support rod 16 is attached to this adjustment rod 18. In this case, the adjustment rod 18 has a thread carved on its outer circumferential surface, and a handle 1 at the end of the adjustment rod 18.
By rotating 9, the support rod 16 can be adjusted to move left and right. Further, this support rod 16 is swingably attached to an adjustment rod 18. Such support rod 1
Reference numeral 8 is used to hold the beam 2 from both sides before starting the welding work to prevent the device from falling.

Next, the handling of this embodiment configured as above will be explained. This device is hoisted onto the beam 2 by a crane or the like before the work starts. Here, the left and right legs 12,1
3 to match the width of the tight frame 3 to be welded, and also adjust the spacing until the support rods 16 sandwich the beam 2 from the left and right. Next, a box loaded with a large number of tight frames is lifted up by a crane, and the box is fitted into the frames 11 and 14. After the preparations have been completed as described above, the operator sits on the pedestal and pulls it with his legs, causing the entire device to move on the beam 2. Therefore, while performing this moving work, the worker takes out the tight frame from inside the box and welds the tight frame to the top surface of the beam so that the tight frame is located inside the leg 12.13. Welding is done. In addition, beam 2
If there is a cross beam that is perpendicular to the cross beam, the support rod 16 will come into contact with the cross beam, but since the support rod 16 will swing when it comes into contact with the cross beam, even if there is a cross beam, it will not cause any hindrance to the moving work.

Note that the present invention is not limited to the above embodiments, and various modifications are possible. For example, the support rod is used to prevent the Tight Frame from falling before welding, and after the Tight Frame is welded onto the beam, the legs that hold the Tight Frame will surely prevent it from falling, so this is omitted. You may.

Further, the device may be automatically moved on the beam by a motor or the like, and both the left and right legs may be slid. This sliding mechanism may also be implemented by means such as a rack and pinion instead of using a long hole and a slider. Furthermore, this device is a tight frame luck t#tt! Kedena (, can be used to load and transport other roof components.

<Effects of the Invention> As described above, according to the present invention, the work of welding a tight frame to the upper surface of a beam can be performed quickly, and workability is improved. Also, a fall from a beam.

This has the effect of not only improving work safety by preventing falls, but also reducing the amount of labor required by the worker.
