DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to embodiments. As shown in FIG. 1 and FIG. 2, four pillar-set carriages 2 and three bracket-set carriages 3 are mounted on a long rail 1. The rods 5 of the pneumatic cylinders 4 attached to the pillar-set carriage 2 are attached to the bracket-set carriage 3 as a connecting means between the two carriages 2 and 3 alternately arranged in front and back, and mutually mounted. As shown in FIG. 3, the front and rear support seats 6 of the pillar set carriage 2 are connected to the left and right ends of the expansion and contraction axis at the left and right ends by connecting them to each other so as to expand and contract with a required connecting force. The pneumatic cylinder 7 is engaged in the direction, the pressing plate 9 is attached to the rod 8 of the pneumatic cylinder 7 in an upright state, and the seat plate of a required thickness is provided in front of the pressing plate 9 (to the right). 17 is attached, and a positioning plate 11 is erected upright on the seat plate 10 having the same thickness as the seat plate 17 on the front and right sides. Made by fastening the wrapper 12, which like engaging position of being selected through a locking hole 13 extending through oppositely arranged at a predetermined pitch toward the right and left support seat 6 around. In addition, the female screw shaft 1 is provided on the left and right ends of the bracket set carriage 3.
Elevating table 15 supported by 4 so as to be able to move up and down
Is provided, and as a holding means at the center of the upper surface of the trolley 3,
As shown in FIG. 4, a stopper 12 having a short height is attached to a support seat 16 on the right side through a locking hole 13, and a pneumatic cylinder 7 is installed below the bifurcated support seat 16 on the left side. Hang up,
On the rod 8 of the pneumatic cylinder 7, a pressing plate 9 which moves in and out between the two forks is attached in an upright state, and a support seat 16 on the left side is attached.
The seat plate 17 of the same thickness as the seat plate 10 of the stopper 12 is provided on the upper surface of the
Is engaged via the locking hole 13.

The temporary assembling apparatus a of the steel frame structure (hereinafter, simply referred to as the present apparatus a) constructed as described above firstly secures the joining straightness of the respective members of the bracket portion 18 and the pillar portion 19, In each carriage, each stopper 12 is attached to each of the support seats 6 and 16 so that the member contact surface of the positioning plate 11 is aligned with the positioning line 20, and the seat plate is placed at a position selected by the width dimension of each member. 17 is attached, and in each pillar set carriage 2, the bottom surface of the pillar 19 is provided with a stopper 12
And the front and rear pneumatic cylinders 7 are simultaneously operated to press the left side of the pillar portion 19 with the pressing plate 9, and the pillar portion 19 is positioned by the positioning plate 11 of the stopper 12. When firmly pinched by the pressing plate 9 and the pillars 19, the pillars 19 on each pillar set carriage 2 are aligned in a straight line. On the other hand, in the bracket set carriage 3, the bottom surface of the bracket main body is placed on the seat plate 10 and the seat plate 17 of the stopper 12, and the lower surfaces of the brackets joined to the left and right sides of the main body are mounted on the left and right lifting bases 15, respectively. When the screw shaft 14 is operated to be lifted to be supported and guided by the upper surface of the lifting table 15 and the pneumatic cylinder 7 is operated in a stable supporting state, the bracket portion 18 is moved to the left side (to be more precise, to the left side of the bracket body). ) Is pressed by the pressing plate 9, but at this time it moves horizontally without tilting to the left and right, the bracket portion 18 is firmly sandwiched between the positioning plate 11 of the stopper 12 and the pressing plate 9, and each bracket portion setting carriage The bracket portions 18 on the upper part 3 are aligned. In this state, if the rod 5 is pulled in by operating the pneumatic cylinder 4 that connects the two carriages 2 and 3, the carriages 2 and 3 are mutually pulled.
Approach each other, and the pillar portions 1 are attached to the front and rear surfaces of the bracket portion 18, respectively.
The end face of 9 is tightly attached, the straightness is ensured with high accuracy, and the temporary assembly is performed by temporary welding.

The pinching means in the present invention is not limited to the one shown in the embodiment of the present apparatus a, and the positioning plate 11 of the stopper 12, which serves as the positioning end of each member, continuously moves in and out by the screw shaft. It may be one,
The connecting means between the two carriages 2 and 3 is also provided with a screw mechanism or a rack and pinion mechanism in addition to the hydraulic pressure. In addition, according to the present invention, detachable receiving seats are provided on the front and rear surfaces of both carriages 2 and 3,
In each of the two carriages 2 and 3, it is easy to recall that the support seat itself can be raised and lowered.

[0009]

As described above, according to the present invention, the straightness of the arrangement of the bracket portion 18 and the pillar portion 19 can be simply and accurately ensured, and the joining in the longitudinal direction can be performed quickly and surely.
This contributes to labor saving and efficiency improvement in temporary assembly work, and is also effective in providing a high-quality steel frame structure.
