step 2, inserting the inner cannula 12 into the outer cannula 11 in a sleeved mode, inserting the inner cannula 12 and the outer cannula 11 into a first through hole 112 of the outer cannula 11 and a corresponding second through hole 122 of the inner cannula 12 through a bolt assembly 13 on the outer cannula 11 according to the supporting height, and adjusting the inner cannula 12 to the required height;
Step 3, two adjacent telescopic vertical rods 1 are fixedly connected through disc-buckling type horizontal rods 2 with equal lengths, and two ends of the disc-buckling type horizontal rods 2 are respectively connected with first horizontal rod buckling holes 1111 of two first connecting discs 111 or second horizontal rod buckling holes 1211 of two second connecting discs 121 with the same height;
Step 4, installing a disc buckle type vertical diagonal draw bar 3 on the outer sleeves 11 of the two adjacent telescopic upright posts 1 supporting the main rib 7, wherein one end of the disc buckle type vertical diagonal draw bar 3 is connected with a first diagonal draw bar buckle hole 1111 of a first connecting disc 111 above one outer sleeve 11, and the other end of the disc buckle type vertical diagonal draw bar 3 is connected with a first diagonal draw bar buckle hole 1111 of a first connecting disc 111 below the other outer sleeve 11;
step 5, installing an adjustable jacking support 5 on the top of each inner insertion pipe 12, and adjusting a third nut 52 on the adjustable jacking support 5 to enable the supporting height to meet the construction requirement;
And 6, arranging a main rib 7, a secondary rib 8 and a template 9 of the beam slab template on the adjustable jacking support 5, and installing according to the prior art.
After each outer sleeve 11 is adjusted to the same elevation, the adjustable base 6 is not being adjusted.
The invention relates to a combined height adjusting mode of a telescopic vertical rod 1 and an adjustable jacking support 5, which comprises the following steps:
When the height of the adjustable jacking support 5 is greater than the design height, the inner insertion tube 12 is adjusted to perform coarse adjustment, so that the height of the adjustable jacking support 5 is slightly greater than the design height (for example, the difference between the height and the design height is smaller than the distance between two adjacent second through holes 122 of the inner insertion tube 12), and then the third nut 52 or the first vertical screw 51 of the adjustable jacking support 5 is adjusted to perform precise adjustment, so that the height of the adjustable jacking support 5 is reduced, and the height of the adjustable jacking support 5 is adjusted to the required height. In this way, in the adjusting process, the vertical height difference h between the top end of the adjustable jacking support 5 and the uppermost disc-buckle type horizontal rod 2 is not increased, and the vertical height difference h can be further reduced, for example, in a specific implementation, the height difference h is adjusted as much as possible to be less than or equal to 200mm, so that the stable bearing capacity of the telescopic upright 1 and the stability of the whole supporting system are improved.
When the height of the adjustable jacking support 5 is smaller than the design height, the inner insertion tube 12 is adjusted to perform coarse adjustment, so that the height of the adjustable jacking support 5 is slightly larger than the design height (for example, the difference between the height of the adjustable jacking support and the design height is smaller than the distance between two adjacent second through holes 122 of the inner insertion tube 12), and then the third nut 52 or the first vertical screw 51 of the adjustable jacking support 5 is adjusted to perform precise adjustment, so that the height of the adjustable jacking support 5 is adjusted to the required height. Similarly, such adjustment has the same advantages as the above one.
Therefore, the height of the telescopic upright 1 is designed to be adjustable, and the telescopic upright is combined with the adjustable jacking support, so that the stability and the stable bearing capacity of the whole support system are greatly improved.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that the specific embodiments described are illustrative only and not intended to limit the scope of the invention, and that equivalent modifications and variations of the invention in light of the spirit of the invention will be covered by the claims of the present invention.
