Abstract
The invention relates to a method for mounting and positioning steel anchor beams for constructing a cable-stayed bridge main tower. The steel anchor beams are mounted and positioned by using a detachable and reusable steel anchor beam support rack system. The detachable and reusable steel anchor beam support rack comprises a rigid support rack I and chain hoists II, wherein the rigid support rack I is arranged on a mounted No. n steel anchor beam and is used for jacking a No. n+1 steel anchor beam; after a No. n+2 steel anchor beam is mounted, four chain hoists II are mounted on the No. n+2 steel anchor beam; the No. n+1 steel anchor beam is hoisted; the rigid support rack I of the steel anchor beams is demounted; then the chain hoists II are used for putting the No. n+1 steel anchor beam in place. According to the detachable and reusable support rack system comprising the rigid support rack and the chain hoists, the steel anchor beams are mounted and positioned; the problem that the construction operation surface is insufficient is solved; the construction period is shortened; the cost is reduced; the device is simple and convenient to operate and convenient to control.
Description
Technical field
Invention relates to a kind of steel anchor beam installation and locating method for Cable stayed Bridge Main Tower construction, is particularly useful for the king-tower steel anchor beam construction lifted after king-tower space can not meet steel anchor beam.
Background technology
On Cable stayed Bridge Main Tower tower, suspension cable anchoring adopts steel anchor beam to bear pulling force and concrete bearing compressive force structure mostly, i.e. the textural association of " steel anchor beam+concrete bracket ".Construction of Pylon adopts segmented construction, and general single segmental comprises two steel anchor beams.When king-tower space can not meet lift after steel anchor beam time, when constructing corresponding sections, before the concrete bracket reinforcing bar of a colligation topmost steel anchor beam, a bottom steel anchor beam must be hung in king-tower.But the concrete bracket that now this steel anchor beam is corresponding does not also build concrete, this steel anchor beam must be built on the steel anchor beam of sections in lower floor by dismountable rigidity bracket support.
Summary of the invention
The present invention will solve the technical problem that Cable stayed Bridge Main Tower steel anchor beam installs location, and the steel anchor beam installation and locating method providing a kind of Cable stayed Bridge Main Tower to construct.
Technical scheme of the present invention is: a kind of steel anchor beam installation and locating method for Cable stayed Bridge Main Tower construction, adopt the steel anchor beam rack system of detachable recycling that location steel anchor beam is installed, comprise rigidity bracket I and Chain block II, rigidity bracket I is shelved on mounted n# steel anchor beam, in order to jacking n+1# steel anchor beam, treat that n+2# steel anchor beam installs, then at n+2# steel anchor beam, four Chain block II are installed, to sling n+1# steel anchor beam, remove steel anchor beam rigidity bracket I, then with Chain block II, n+1# steel anchor beam is in place.
Rigidity bracket I comprises longitudinal and transverse beam, longitudinal and transverse link rod, diagonal brace, angle brace, backing plate, longeron is fixed in backing plate upper end, fixed cross beam on longeron, middle part is fixedly connected with longitudinal and transverse link rod, be connected to diagonal brace between longitudinal and transverse beam, angle brace, connected by junction plate between crossbeam, junction plate is fixed by pull bar, and backing plate is fixed by limiting plate.
Useful achievement of the present invention is: a whole set of rack system consisted of rigidity bracket and Chain block, realize the installation location of steel anchor beam, the problem of operation side deficiency can be solved, the effective shortening Construction of Pylon duration under the prerequisite meeting safety and quality requirement.This device is easy and simple to handle, and it is convenient to control.

Concrete operation method of the present invention:
1) treat that last sections concreting is complete, after putting in place by specification maintenance, the n# steel anchor beam 12 installed places rigidity bracket I11, n+1# steel anchor beam 13 is installed, is shelved on rigidity bracket I11.
2) when n+1# steel anchor beam 13 is installed, absolute altitude exceeds design and installation position and is about 15cm.
3) assembling reinforcement is continued to completing second anchoring bracket.
4), after this section concreting completes, after reaching the intensity of design code, n+2# steel anchor beam 14 is installed.
5) on n+2# steel anchor beam 14, Chain block II10 is installed, utilizes Chain block II10 to be lifted by crane by n+1# steel anchor beam 13, hang rigidity bracket I11 certain distance.
6) screw rod of rigidity of dismantling bracket I11, disintegrates rigidity bracket I11 and hangs out king-tower.
7) utilize Chain block II10 to be transferred to by n+1# steel anchor beam 13 on corresponding steel anchor beam bracket, complete the construction of a sections.
