Description
Technical field
The present invention relates to a kind of Coordinate Adjusting device, particularly a kind of Support Method when installing tubular arch arch sections and CFST X-type arch arch sections Coordinate Adjusting device is installed.
Background technology
Because the physical dimension of the arch sections of long-span Steel Arch is large, weight is large, need to adopt large lifting equipment lifting, when tubular arch sections is installed, mileage direction error of coordinate can by last closure section length adjustment of installing, and the coordinate that is horizontal, height of the arch sections mouth of pipe needs accurately location.Because CFST X-type arch arch sections mouth of pipe three-dimensional coordinate can interact when adjusting, needing repeatedly to adjust and just can reach requirement, and it is very difficult to use large lifting equipment accurately to locate arch sections position.
Common way is large lifting equipment cooperation, and manually by jack, small-size jack draws, pushing tow operates, and not only there is accurate adjustment arch pipe joint mouth coordinate in construction needs to expend for a long time, and there is the risk of constructor by object strike in operation.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Support Method that can steel tube arch rib mouth of pipe absolute altitude be made to reach installation requirement fast, safely, accurately and installs tubular arch arch sections Coordinate Adjusting device.
For solving above technical problem, the present invention by the following technical solutions.
A kind of Support Method installs tubular arch arch sections Coordinate Adjusting device, comprise sliding base, grooved slideway, rack beam, slideway support post, traversing jack, vertical shift jack and cross spacing frame, two cross spacing framves are separately fixed at rack beam two ends, two slideway support posts and two vertical shift jack are individually fixed in rack beam both sides, grooved slideway is supported in above slideway support post and vertical shift jack, sliding base loads in flute profile slideway, and traversing jack is arranged between sliding base and cross spacing frame opposite flank.
Tubular arch arch sections is arranged on sliding base, and sliding base laterally can slide in grooved slideway under the effect of horizontal jack, and grooved slideway can move up and down under the effect of vertical jack, thus tubular arch is encircleed sections accurately locates.
As the preferred scheme of one, described sliding base comprises sliding base base plate, and vertical sliding base base plate is fixed with sliding base web, and sliding base web stiffener is fixed in sliding base web both sides.
As the preferred scheme of another kind, between slideway support post and flute profile slideway, be provided with billet.Space billet between grooved slideway and slideway support post, when laterally sliding, pads, avoids flute profile slideway to tilt by base.
Adjusting device of the present invention can regulate tubular arch arch sections to reach absolute altitude fast, safely, exactly, decreases construction workload, reduces difficulty of construction, ensure that homework precision and construction safety.
