Description

[Detailed Description of the Invention] The present invention relates to a welding jig used for welding plate metal to the end face of a steel frame member.

Steel frames used in construction of prefabricated houses, etc.
In place of commercially available channel steel from the viewpoint of strength, etc., when using a steel plate of an appropriate thickness with sound grooves or a steel frame processed into a C shape, either alone or in combination, and then using these metals. There is.

If you try to use the C-shaped steel frame by itself as a column or support, you will have to do play welding to fix it at one or both ends.

Conventionally, the end of a steel frame member fixed to a welding jig was pressed against the end of the steel frame member at the correct dimensional position using a welding plate 1 - a suitable tool, and the contact points were metal welded.

In this case, if the pressure of the welding plate is weak, the welding plate will move due to the force applied during welding, resulting in poor dimensional accuracy. This results in high processing costs.

The present invention provides a welding plate feeding device that can solve this problem.

In the drawings showing the present invention, reference numeral 1 indicates a rear fixing part 4 which is connected to rear wall plates 2, 2' facing each other at a predetermined interval by a horizontal end metal connecting plate 3, and is connected in parallel with the rear wall plates 2, 2'. A front fixing part 6 consisting of a front wall plate 5.5' facing the side end face side where there is no plate 3;
and sliding rods 7, 7 connected on the outer sides of the rear wall plate 2 or 2' and the front wall plate 5, respectively, and holding the rear fixing part 4 and the front fixing part 6 at predetermined intervals. One end of the sliding plate 8 and the string 9 or 9', which are held slidably through the upper part near both ends, is fixed to the upper part near both ends of the sliding plate 8, and the other end is fixed to the upper part near both ends of the sliding plate 8, and the other end is fixed to the upper part near both ends of the sliding plate 8. A welding plate supply device [string 9', guide wheel 13'] consisting of a load section 12 fixed to a weight 11 or 11' through a guide wheel 10 casing or 10' metal which is fixed to the outer part of the guide wheel 13'. and weight 14' are not shown].

A method of using an embodiment of the present invention is to place a welding plate supply device 1 near the end of a jig stand 13 equipped with a 14-karat gold fixture so that the rear fixing part 4 is at the end of the jig stand 13. It is attached and fixed to both side walls of the jig stand 13 by welding or screwing to the rear wall plates 2, 2' and the front wall plates 5, 5'.

Next, a large number of welding plates 1 are provided between the front fixed part 6 and the sliding plate 80.
5... Insert the metal, place one end of the steel member 16 against the outermost welding plate 15, and fit it between the fixtures 2.

Subsequently, the contact portions of the steel frame member 16 and the welding plate 15 are welded.

Since the sliding plate 8 is pulled toward the front fixed part 6 by the weights 11 and 11', the welding plate 15 is always crimped to the end face of the steel member 16, and some force is applied to the welding plate 15 during welding. Welding can be performed with high dimensional accuracy without any movement.

Also, when the external welding plate 15 is used and is moved outward, the sliding plate 8 moves by the weights 11 and 11' and presses the external welding plate 15, so the steel frame member 16 which is There is no need to install a welding plate every time the condition changes.

In the above embodiment, the string 9.9' is used to pull the sliding plate 8 gold.
However, materials made of metal or synthetic resin may also be used as long as they have flexibility and tensile strength.

Also, the load portion 12 to be moved to the sliding plate 8 is a purple guide wheel io, in
' and weights 11, 11', but other methods such as attaching a bullet bar between the sliding plate 8 and the rear wall plates 2, 2', or It is also possible to use a load portion such as a tensioning bullet bar between 5 and 5'.

As described above, the present invention is a welding jig consisting of a jig stand provided with a fixture for fixing a steel frame part by hammering, and a welding plate supply device provided at one end of this stand. However, a pair of rear wall plates 2, 2' are erected facing each other on the left and right so that both ends of the welding plates are in contact with each other, and the welding plate is parallel to the rear wall plates 2, 2' in the front and rear directions. A pair of front side wall plates 5, 5' are erected facing each other on the left and right so that both ends of the plate are in contact with each other. side wall plate 5,
The sliding rods 7 and 7' are connected to the left and right sliding rods 7 and 7', and are held slidably back and forth between the sliding rods 7 and 7', and are always in pressure contact with the wall plate. One end surface of the steel frame member fixed to the fixture is in contact with the surface of the welding plate pressed against the front wall plates 5, 5', so that welding is prevented. Plate metal can be accurately welded to steel members in a short time.

In other words, the jig table is equipped with a fixture for fixing the steel frame parts with a hammer, and a welding plate supply device is installed at one end of the jig table, so that the steel frame parts fixed by the fixtures and the welding plate supply device are provided at one end of the jig table. The positional relationship between the welding plate and the welding plate is constant, and the welding position of the welding plate is accurate even when a large number of steel members are sequentially welded to the welding plate.

Moreover, since the welding plate is held horizontally, vertically, and at an angle by the welding plate supply device, it is possible to weld to the end face of the steel frame member in a constant state.

First, the welding plate is always pressed against the wall plates 5, 5' by the sliding plate, so it maintains the same posture. Since both the left and right sides are corrected, they come into contact with the steel frame member at a fixed position.

Additionally, since both the rear wall plate and the front wall plate are erected facing each other on the left and right, it is possible to easily replenish the welding plate metal by pulling the sliding plate towards the rear, and also when welding is completed. The steel member can be removed from the welding jig by lifting it upward.

Furthermore, since a pressing force is applied to the welding plate by the sliding plate, it is possible to weld by pressing the steel part with the welding plate, and the next welding plate can be attached immediately after welding is completed and the welding play Hr is removed together with the steel part. Since it is set, the work can be done by one person in a short time.

As described above, the present invention allows welding plates that require dimensional accuracy and are heavy in weight to be easily welded to steel members.
