Embodiment 1

[0028] Embodiment one sees figure 1 As shown, the low-level jacking steel platform formwork system includes a formwork system hydraulic synchronous jacking device supported on the core tube shear wall 8, which is connected to the formwork system hydraulically synchronously through the support column 3 of the standardized low-position jacking formwork system. The steel platform 1 above the jacking device, and the hanger 2 and the template 7 suspended on the steel platform 1. The steel platform can be an ordinary steel frame platform or an assembled variable steel truss platform, and the hanger can be an ordinary hanger or an adjustable hanger. The entire formwork system of the low-level jacking steel platform often requires three or four sets of hydraulic synchronous jacking devices for the formwork system.

[0029] see figure 1 , Figure 4 , Figure 5The hydraulic synchronous jacking device of the formwork system includes an upper support beam 5, a lower support beam 6 and...

Embodiment 2

[0035] Embodiment two see figure 2 , there is an increasing section 19 connected between the lower end of the piston rod 4.2 of the jacking cylinder 4 and the lower support beam main body 6.1, see image 3 , the added section 19 includes a round steel pipe 19.1, the upper end of the round steel pipe 19.1 is connected with an upper flange 19.2, the lower end of the round steel pipe 19.1 is connected with a lower flange 19.3, an upper flange 19.2, and a lower flange 19.3 Also be connected with back corrugated 19.4 between the sidewall of round steel pipe 19.1. The added section is connected to the piston rod through the upper flange and bolts, and the added section is connected to the main body of the lower support beam through the lower flange and bolts. The distance between the upper and lower support beams can be adjusted by adding or canceling the added section.

[0036] see Figure 7 , the present invention also has a pumping station 34, a touch-type operating table 35,...

Abstract

The invention discloses a hydraulic synchronous jacking device of a die carrier system. The hydraulic synchronous jacking device comprises an upper supporting cross beam, a lower supporting cross beam and a jacking oil cylinder connected between the upper supporting cross beam and the lower supporting cross beam, wherein the jacking oil cylinder is placed upside down and passes through the main body of the upper supporting cross beam from bottom to top; a cylinder flange plate for connecting the cylinder body of the jacking oil cylinder is welded on the lower part of the cylinder body of the jacking oil cylinder, and is connected with a cross beam flange plate, which is welded on the lower surface of the main body of the upper supporting cross beam, through bolts; the upper surface of themain body of the upper supporting cross beam is provided with an upper supporting cross beam elongated slot, and the cylinder body of an upper cantilever outrigger driving cylinder is also fixedly connected to the upper surface of the main body of the upper supporting cross beam; and the upper surface of the main body of the lower supporting cross beam is provided with a lower supporting cross beam elongated slot, and the cylinder body of a lower cantilever outrigger driving cylinder is also fixedly connected to the upper surface of the lower supporting cross beam. The hydraulic synchronous jacking device saves the vertical construction space for a low-position jacking die carrier system to ensure that the assembly height of a steel platform is greatly reduced, so the hydraulic synchronous jacking device is convenient for construction, and can improve the construction efficiency.

Description

technical field [0001] The invention relates to a jacking device used in a low-position jacking steel platform formwork system. Background technique [0002] In the construction of core tubes of existing high-rise and super high-rise building structures, it is rare to use low-level jacking steel platform formwork systems, and it has only been used in individual projects. There are few fulcrums in the existing low-level jacking formwork system, so the hydraulic jacking power system in the jacking support system generally uses a large-tonnage, long-stroke hydraulic cylinder as the jacking cylinder. The bearing capacity of this jacking cylinder Large, when the stroke exceeds 5m~6m, the jacking capacity can reach more than 300t, and due to the large stroke, the jacking cylinder can lift the steel platform to the position at one time according to the floor height, and then directly support it on the core wall through the supporting beam In addition, because there is no need to s...
