Abstract
The present invention relates to a kind of steel anchor beam installation and locating method for Cable stayed Bridge Main Tower construction, the steel anchor beam rack system using detachable recycling installs location steel anchor beam, including rigidity bracket I and chain block II, rigidity bracket I is shelved on the most 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, 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.The present invention, by rigidity bracket and the rack system of the detachable recycling of chain block composition, realizes the installation location of steel anchor beam, it is possible to resolve the problem that operation side is not enough, reduction of erection time and cost-effective, and this device is easy and simple to handle, easy 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 suited for the king-tower steel anchor beam of lifting after king-tower space can not meet steel anchor beam and constructs.
Background technology
On Cable stayed Bridge Main Tower tower, suspension cable anchoring uses steel anchor beam to bear pulling force and concrete bearing compressive force structure, the i.e. structural grouping of " steel anchor beam+concrete bracket " mostly.Construction of Pylon uses segmented construction, and general single segmental comprises two steel anchor beams.When lifting after king-tower space can not meet steel anchor beam, when constructing corresponding sections, before the concrete bracket reinforcing bar of a colligation steel anchor beam topmost, it is necessary to one, bottom steel anchor beam is hung in king-tower.But the concrete bracket that now this steel anchor beam is corresponding does not the most pour concrete, it is necessary to this steel anchor beam has been poured on the steel anchor beam of sections in lower floor by dismountable rigidity bracket support.
Summary of the invention
The present invention is to solve that Cable stayed Bridge Main Tower steel anchor beam installs the technical problem of location, and the steel anchor beam installation and locating method that a kind of Cable stayed Bridge Main Tower constructs is provided.
The technical scheme is that a kind of steel anchor beam installation and locating method for Cable stayed Bridge Main Tower construction, the steel anchor beam rack system using detachable recycling installs location steel anchor beam, including rigidity bracket I and chain block II, rigidity bracket I is shelved on the most 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, 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 includes longitudinal and transverse beam, longitudinal and transverse link rod, diagonal brace, angle brace, backing plate, backing plate upper end fixes longeron, fixed cross beam on longeron, middle part is fixing connects longitudinal and transverse link rod, it is connected to diagonal brace, angle brace between longitudinal and transverse beam, is connected by connecting plate between crossbeam, connecting plate is fixed by pull bar, and backing plate is fixed by limiting plate.
The useful achievement of the present invention is: a whole set of rack system consisted of rigidity bracket and chain block, it is achieved the installation location of steel anchor beam, it is possible to resolve the problem that operation side is not enough, the effective shortening Construction of Pylon duration on the premise of meeting safety and prescription.This device is easy and simple to handle, easy to control.

Detailed description of the invention
Below in conjunction with instantiation, the embodiment of of the present invention patent is expanded on further.
Such as Fig. 1, shown in 2,3,4, the steel anchor beam installation and locating method for Cable stayed Bridge Main Tower construction of the present invention, the steel anchor beam rack system of detachable recycling is used location steel anchor beam to be installed, including rigidity bracket I11, chain block II10.
Rigidity bracket I11 is shelved on the most mounted n# steel anchor beam 12, in order to jacking n+1# steel anchor beam 13, treat that n+2# steel anchor beam 14 installs, then at n+2# steel anchor beam 14, four chain block II10 are installed, sling n+1# steel anchor beam 13, remove steel anchor beam rigidity bracket I11, then with chain block II10, n+1# steel anchor beam 13 is in place.
Rigidity bracket II10 includes longitudinal and transverse beam 1,2, longitudinal and transverse link rod 3, diagonal brace 4, angle brace 5, backing plate 6, longeron 1 is fixed in backing plate 6 upper end, fixed cross beam 2 on longeron, and middle part is fixing connects longitudinal and transverse link rod 3, longitudinal and transverse beam 1, it is connected to diagonal brace 4, angle brace 5 between 2, is connected by connecting plate 7 between longitudinal and transverse link rod 3, connecting plate is fixed by pull bar 9, and backing plate 7 is fixed by limiting plate 8.
The concrete operation method of the present invention:
1) treat that previous sections concreting is complete, after putting in place by specification maintenance, the n# steel anchor beam 12 installed is placed 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 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) chain block II10 is installed on n+2# steel anchor beam 14, 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) chain block II10 is utilized to transfer to n+1# steel anchor beam 13, on the steel anchor beam bracket of correspondence, complete the construction of a sections.
