As shown in (2), when the apparatus is used in a place where the floor F is at the upper part, the temporary beam 10 and the load equalizer 3 need a space for the top beam empty space, so that the space cannot be used (there is no installation space). In addition, since the crane cannot be used, the temporary receiving beam 10 cannot be attached or detached.

[0007] Accordingly, an object of the present invention is to provide a push-push system which can be used even when a building frame such as a floor is provided at the top, and in which a temporary support beam can be attached and detached without using a crane. To provide an up device.
Another object is to provide a push-up device capable of adjusting the level and the inclination of the temporary beam in a state where the temporary beam is mounted.

[0008]

According to the present invention, a column is erected on a base, and four tension rods are suspended from a top beam provided on the top of the column so as to exhibit a plane quadrilateral,
An upper load receiving beam and a lower load receiving beam are inserted through the tension rods, a main jack is provided between the load receiving beams, and a screw is screwed into a male screw formed on each tension rod below the load receiving beams. Provide a rotating nut, place the building skeleton on the upper load receiving beam, expand and contract the main jack to raise the upper load receiving beam and the lower load receiving beam in a worm-like manner, and follow the rotating nut to sequentially build the building skeleton. In the push-up device for raising, the building frame is pushed up to the pillar, and then, when the next building frame is added, the building frame raised first is replaced with the temporary load supporting beam to support the building frame. A driver who forms a horizontal hole through which the receiving beam passes, moves the temporary receiving beam horizontally through the hole, detaches the temporary receiving beam, and moves the temporary receiving beam horizontally. And the level of the temporary receiving beam is provided with a sub jack for adjusting the inclination.

[0009]

[Function] At the time of push-up, the temporary receiving beam is pulled out from the horizontal hole of the pillar. When pushing up the building frame (main body column) and then adding the next building frame, the temporary beam is moved horizontally through the hole of the column by means of the temporary beam driving means and mounted on the column. The level and inclination of the temporary receiving beam are adjusted by the sub jack. In the temporary beam installed in this way, the building frame that was raised first was replaced from the upper load beam of the push-up device, and the temporary frame supported the building frame,
The push-up device is temporarily removed and the next building skeleton is added. After the building frame is completed, a push-up device will be installed to perform the next push-up.

[0010]

In FIGS. 14 and 15, T is a main pillar which is a building frame. As shown in FIG. 15, there is a floor F at the top, and the space at the head of the top beam 2 is narrow. For this reason, the temporary receiving beam 10 and the load equalizer 3 cannot be placed on the top beam 2. Therefore, a horizontal through hole 11 for passing the temporary receiving beam 10 is formed in the column 1 immediately below the top beam 2, and the temporary receiving beam 10 is horizontally moved through the hole 11 to move the temporary receiving beam 10 horizontally.
Desorption. Reference numeral 12 denotes a stay for supporting the temporary receiving beam 10. FIGS. 14 and 15 show a state in which the temporary receiving beam 10 is mounted. The temporary receiving beam 10 is prevented from coming out by inserting a pin 13 therein. Further, the load equalizer 3 is not provided on the top beam 2 but is provided between the upper load receiving beam 5 and the rotating nut 8 and between the lower load receiving beam 6 and the rotating nut 8.

FIG. 16 and FIG. 17 show driving means for moving the temporary receiving beam 10 horizontally. In FIG. 16, a driving roller 15 is rotated by a geared motor 14, and a driven roller 16 is rotated via a chain 17. FIG. 17 shows details of a drive (following) roller. A roller 15 (16) is rotatably supported by upper and lower brackets 19 via a thrust bearing 20, and a hydraulic tube is provided on the outer periphery of the roller 15 (16). The roller 15 (16) is rotated by a chain 17 and a sprocket 21 via a swivel joint 22. When the temporary receiving beam 10 is moved horizontally, the temporary liquid is sent to the tube 18 to be inflated and pressed against the temporary receiving beam 10, and the roller 15 (16) is rotated to move the temporary receiving beam 10. The pressure liquid is drained from the tube 18 except when the temporary receiving beam 10 is detached.

Referring to FIGS. 14 and 15, the column 1
Is provided with a sub jack 23 for supporting the front and rear two portions of the temporary receiving beam 10 and adjusting the level and inclination of the temporary receiving beam 10.

FIG. 18 shows a push-up control system which controls a valve stem based on a signal from a CPU.
The hydraulic fluid is supplied and discharged from the hydraulic pump to the drive motors of the load equalizer 3, the main jack 7, and the rotating nut 8 described above. Further, the hydraulic fluid is supplied to the sub jack 23.
The level and the inclination of the temporary receiving beam 10 are adjusted in the mounted state of the temporary receiving beam 10 shown in FIGS. 14 and 15. This allows the building frame to be pushed up with high precision.

[0014]

The push-up device according to the present invention can be used even when there is a building body such as a floor on the upper part. In such a case, a crane cannot be used, but the temporary receiving device can be used without using a crane. The beam can be attached and detached. In addition, the level and the inclination of the temporary beam can be adjusted in the mounted state of the temporary beam, and push-up can be performed with high accuracy.
