Abstract

The invention relates to a method for hoisting a large-sized component through air bags. The method is characterized in that the lower side of the component is provided with two or more than two air bags, and the air bags are charged with air or water to hoist the component. The action areas of the air bags occupy 10 to 45 percent of the bearing load areas of the component bottom. The method aims to solve the technical problems that the large-sized component adopts the conventional hoisting method of a hydraulic jack, the hoisting point load is centralized, and the prior method has the disadvantages of high base requirements, large construction difficulty, high cost, low efficiency and poor safety. The invention provides the technical method for hoisting the large-sized component through the air bags to replace the prior hoisting method of the hydraulic jack and makes use of the characteristics of large air bag bearing area and dispersed load to greatly reduce the requirements on base load force, ensure that the hoisted objects are not damaged and meet the jacking requirements of various ultra-large size components.

For addressing the above problem, the present invention by the following technical solutions:

Large-scale component jacking method is characterized in that: arrange two or more air bag below member, give airbag aeration or water-filling, component jacking is got up.The active area of air bag account for that member bottom can stress bearing area 10%~45%.

Below be the further improved technical scheme of such scheme:

Described large-scale component jacking method is the position that reserves hoisting gasbag below member, penetrates hoisting gasbag when member needs jacking.

Described large-scale component jacking method is on the workplatform below member several hoisting gasbag grooves to be set.

The hoisting gasbag groove of described large-scale component jacking method is provided with slot cover and cover plate, and the last plane of cover plate and workplatform are same planes, and air bag can penetrate in the air bag groove below the cover plate.

The height of the air bag groove of described large-scale component jacking method is 40mm~300mm.

The height of the air bag groove of described large-scale component jacking method is 50mm~240mm.

Be provided with cover plate above the hoisting gasbag groove of described large-scale component jacking method, cover plate can be wooden, also can be steel or ferro-concrete.

Be provided with cover plate above the hoisting gasbag groove of described large-scale component jacking method, the thickness of cover plate is 50mm~300mm.

Be provided with cover plate above the hoisting gasbag groove of described large-scale component jacking method, during jacking, give airbag aeration or water-filling, cover plate is by air bag jack-up from slot cover, and plane effect finishes at component jacking in the bottom of member on the cover plate, give air bags or draining, cover plate falls back in the slot cover.

Described large-scale component jacking method be below member, reserve the basis of several hoisting gasbag grooves and workplatform can pour into an integrated entity or respectively the cast.

Beneficial effect

Large-scale component jacking method of the present invention, a kind of process with air bag jacking large-scale component is provided, replace conventional hydraulic jack jack-block, utilize the characteristics that the air bag loaded area is big, load is disperseed, the air bag active area account for that member bottom can stress bearing area 10%~45%, reduce the requirement to ground bearing pressure greatly, general ground bearing pressure is at 50t/m 2Can satisfy the jacking requirement of large-scale component, and can guarantee by the jacking object injury-freely, satisfy the jacking needs of various super-large components.

For some large-scale component factory for prefabrications, go up several hoisting gasbag grooves of reservation at workplatform (prefabricated platform), lay cover plate above the air bag groove, whole place is very smooth, can lay end template very easily, carries out the prefabricated of concrete member.

Hoisting gasbag groove design-calculated is long as far as possible, connects a plurality of prefabricated platforms, and air bag drags in the air bag groove below each member easily, can satisfy the component jacking of all size.

Safety king-sized for the hoisting gasbag operation pressure, come for the air bag water-filling than inflation, and stability will be got well.

The invention will be further described below in conjunction with drawings and Examples:

Description of drawings

Accompanying drawing 1 is large-scale component jacking air bag trench pattern scheme drawing of the present invention;

The scheme drawing that accompanying drawing 2 is got up by the air bag jacking for large-scale component of the present invention;

Accompanying drawing 3 is reserved the scheme drawing of hoisting gasbag position for large-scale component of the present invention bottom;

Among the figure: the 1st, member, the 2nd, workplatform, the 3rd, cover plate, the 4th, air bag, the 5th, air bag groove, the 6th, slot cover, the 7th, air bag groove basis, the 8th, a underbed.
