Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a reinforcing member that temporarily attaches a reinforcing member, for example, a diaphragm or an end plate to each end side temporary attaching position of a square tubular pillar base material. Regarding the tacking method. It can be used to manufacture the columns that make up the framework of a residential unit.

[Background technology]

The skeleton of the housing unit that constitutes the unit housing is constructed by welding beams to both ends of a square tubular pillar. When welding a beam to both ends of a column, a diaphragm is welded in both ends of the column in order to increase the strength of the column end where the beam is welded. In addition, end plates are welded to both end faces of the pillar in order to fix the unit housing to a foundation or to connect the upper and lower housing units to each other.

Conventionally, when welding diaphragms inside both ends of a pillar,
In advance, at the temporary attachment position of the diaphragm on both ends of the pillar,
Diaphragm temporary mounting holes are drilled in three outer surfaces of the outer side surfaces, and the diaphragms are set at the temporary mounting positions in both ends of the column. In this state, the diaphragms are inserted from the three temporary diaphragm mounting holes at each end. The work procedure is to weld the entire circumference of the diaphragm with a welding robot or the like after temporarily welding to the pillar.

Also, when welding the end plates to both ends of the pillar,
Set the end plates on both ends of the pillar, and in this state, temporarily weld the end plates to the pillar from the 3 outer surfaces of the 4 outer surfaces of each end of the pillar, and then weld the entire circumference of the end plate to a welding robot, etc. The work procedure for welding is adopted.

[Problems to be Solved by the Invention]

However, in the past, in tack welding of diaphragms and tack welding of end plates, tack welding was performed by positioning the column in a horizontal posture (the posture where one outer surface of the pole is horizontal) and performing tack welding. Pillar 3 while still in place
It was extremely difficult to tack weld the diaphragm and end plate from the surface.

For example, when the pillar is positioned in a horizontal position with the non-temporary surface of the pillar as the lower surface, temporary welding of the front surface and the upper surface of the pillar can be performed relatively easily for the worker, but the rear surface of the pillar is relatively easy. There is a problem that the tack welding for the side is difficult because the tack welding is on the back side of the operator with the column in between.

Here, an object of the present invention is to eliminate such a drawback of the related art, and to easily provide a reinforcing member such as a diaphragm or an entrapping plate on the pillar base material from three surfaces of the pillar base material while the operator is in a fixed position. It is to provide a method for temporarily attaching a reinforcing member that can be temporarily attached.

[Means for solving the problem]

Therefore, the tacking method of the reinforcing member of the present invention is a tacking method of the reinforcing member that tacks the reinforcing member to both end side tacking positions of the rectangular columnar column base material, and is before the tacking work position. To
The pillar base material is positioned in a substantially horizontal posture with its longitudinal direction oriented in the left-right direction, and one corner portion of the pillar base material is located at the lowermost side and is adjacent to each other with the corner portion sandwiched therebetween. Two
Position the outer surface so that the angle between the outer surface on the temporary work position side and the horizontal surface is larger than the angle between the outer surface on the opposite side to the temporary work position and the horizontal surface. After setting the reinforcing member at the temporary attachment positions on both end sides of the base material, the reinforcement member is formed from the 3 outer surfaces of the 4 outer surfaces of the column base material, excluding the outer surface on the opposite side of the temporary attachment work position. It is characterized in that it is tack welded to the material.

[Action]

Before the temporary working position, the pillar base material is positioned in a substantially horizontal posture with its longitudinal direction oriented in the left-right direction, and one corner of the pillar base material is located at the bottommost surface, and The angle formed between the horizontal surface and the outer surface on the temporary working position side of the two outer surfaces adjacent to each other with the portion sandwiched is larger than the angle formed by the horizontal surface and the outer surface on the opposite side to the temporary working position. After positioning and setting the reinforcing members at the temporary attachment positions on both end sides of the pillar base material in this state, out of the 4 outer surfaces of the pillar base material, except the outer surface on the side opposite to the temporary attachment work position, 3 outer surfaces Since the reinforcement member is tack welded to the column base material from the side surface, the worker can easily attach the reinforcement member such as the diaphragm or end plate to the column base material from the 3 outer sides of the column base material while staying in the tacking work position. Can be temporarily attached to.

At this time, of the two outer side surfaces adjacent to each other with one corner located at the lowermost side of the pillar base material, the outer side surface on the side of the temporary work position is inclined downward, so that the temporary welding work is performed. However, in the present invention, the angle between the outer surface on the temporary working position side and the horizontal plane is set to be larger than the angle between the outer surface on the opposite side to the temporary working position and the horizontal plane. That is, since the angle between the outer surface on the tacking work position side and the horizontal surface is positioned at an angle greater than 45 degrees, it is easy to perform tack welding work on the outer surface on the tacking work position side. You can

A recess 99A for fitting the diaphragm 34B and positioning the diaphragm 34 at a position corresponding to the inclination of the pillar base material 31 is formed.

Next, the operation in the temporary diaphragm attaching step 46 will be described.

The pillar base material 31 that has been conveyed in the longitudinal direction in the horizontal posture by the first conveyer conveyor 42 is first pushed out by the pusher 61 in the perpendicular direction. Then, the pillar base material 31,
Two inclined rails 62A, 62B and inclined roller conveyor 63
It slides down A and 63B, and is supported by the support member 73 of the support mechanisms 71A and 71B.

At this time, in the pillar base material 31, two adjacent outer surfaces are supporting members.
The L-shaped support surfaces 73A and 73B of the 73 are automatically positioned in a posture inclined with respect to the horizontal plane and in a posture in which the longitudinal direction is substantially horizontal.

Therefore, the suction member 8 of each diaphragm set mechanism 81, 91
After the diaphragm 34 is suction-held on the 9,99 in a predetermined posture, the cylinder 86 of one diaphragm setting mechanism 81 is driven. Then, the movable base 84 is connected to the pillar base material via the link 85.
Since a certain amount is advanced toward the end face of 31, the contact member 84
With the contact surface of B in contact with the end surface of the pillar base material 31, the pillar base material 31
Is extruded by a predetermined amount in the axial direction.

Thereby, after the pillar base material 31 is positioned in the longitudinal direction, the clamp member 75 is rotated about the pin 74 as a fulcrum to clamp the pillar base material 31 from above.

After this, the movable base 94 of the other diaphragm setting mechanism 91
Is moved toward the end surface of the column base material 31 along the guide rod 93, and the contact surface of the contact member 94B is brought into contact with the end surface of the column base material 31.

Here, the gripping ring 88 of each diaphragm setting mechanism 81, 91,
When 98 is gripped and pushed in, the advance / retreat rods 87, 97 are respectively advanced. Then, the diaphragm 34 is inserted into the end of the pillar base material 31 together with the suction members 89 and 99. Eventually, when the gripping wheels 88, 98 are advanced to a position where they cannot be pushed in, the diaphragm 34 is set to the temporary attachment position in both ends of the pillar base material 31.

In this state, the diaphragm 34 is temporarily welded to the outer peripheral surface of the pillar base material 31 at three positions, that is, from the three diaphragm temporary holes 32. At this time, as shown in FIG. 12, since the three diaphragm temporary mounting holes 32 of the column base material 31 face the operator, the worker can easily perform the temporary welding while staying in the fixed position, and the welding head Can be left facing down. Moreover, the angle between the outer surface on the temporary working position side and the horizontal surface is specifically set at 60 degrees so that the angle between the outer surface on the opposite side of the temporary working position and the horizontal surface is larger. Therefore, the tack welding work on the outer surface on the tacking work position side can be easily performed.

Therefore, according to the present embodiment, when temporarily welding the diaphragm 34 set at the temporary tacking position in the end portion of the pillar base material 31,
Since the pillar base material 31 is temporarily welded to the diaphragm 34 in a state in which the two adjacent outer side surfaces are inclined with respect to the horizontal plane and the longitudinal direction is positioned substantially horizontal, the pillar base material 31 is welded. Since the three diaphragm temporary mounting holes 32 formed in the diaphragm temporary mounting positions 31 are oriented toward the worker, the worker can easily perform the temporary welding at the three temporary mounting positions while staying in the fixed positions. Moreover, since the welding to these three temporary diaphragm holes 32 can be performed with all the welding heads facing downward, the quality can be stabilized.

Further, the carried-in pillar base material 31 is automatically positioned by the support mechanisms 71A and 71B in a posture in which the two adjacent outer side surfaces are inclined with respect to the horizontal plane and in a posture in which the longitudinal direction is substantially horizontal. The mechanism for positioning the pillar base material 31 can be simplified. That is, there is an advantage that a pusher or the like as in the past is not required.

Further, on both end sides of the column base material 31 supported by the support mechanisms 71A, 71B, movable bases 84, 9 movable in the axial direction of the column base material 31.
4, a diaphragm set mechanism 81 comprising an advancing / retreating rod 87, 97 that can move back and forth in the axial direction of the pillar base material 31 on the movable bases 84, 94 and a suction member 89, 99 attached to the inner end of the advancing / retreating rod 87, 97 Since 91 is arranged, the movable bases 84 and 94 are moved toward the end surface of the pillar base material 31 and abutted while the diaphragm 34 is suction-held to the suction members 89 and 99, respectively, and then the advancing and retracting rods 87 and 97. By advancing, the advancing / retreating rods 87, 97 are regulated so that the advancing amount from the contact surface is constant, that is, the inserting amount of the diaphragm 34 is regulated based on the end face of the pillar base material 31. Therefore, the diaphragm 34 can be accurately set at the temporary attachment position in the end portion of the pillar base material 31.

The present invention is not limited to the above-described embodiments, and includes the following modifications.

For example, the tilt angles of the support surfaces 73A and 73B that support the two adjacent outer surfaces of the pillar base material 31 are not limited to the angles described in the above embodiment. The point is that the diaphragm 34 can be easily tack-welded to the pillar base material 31 from the three diaphragm tacking holes 32 drilled at the diaphragm tacking positions of the pillar base material 31 while the operator is in a fixed position. Good.

In the above embodiment, only the movable base 84 of the one diaphragm setting mechanism 81 is automatically moved by the cylinder 86, but the other diaphragm setting mechanism 91 is used.
The movable table 94 may also be automatically moved by a driving means such as a cylinder. Furthermore, advance / retreat rod 8
The 7,97 may also be moved back and forth by driving means.

Further, in the above-mentioned embodiment, the suction means for suction-holding the diaphragm 34 is constituted by the suction members 89, 99 made of permanent magnets, but the diaphragm 34 may be suction-held by suction of air.

In the above description, in the temporary diaphragm attaching step 46,
Although the example in which the diaphragm 34 is tack-welded to the pillar base material 31 has been described, it is also applicable to the case where the end plate 35 is tack-welded to the pillar base material 31 in the end plate tacking step 50. .

〔The invention's effect〕
