Cloth is intensive, and especially center pillar has the construction connecting with more beams, and when using whole heavy beam, stirrup binding is difficult, and there are omission columns
Stirrup or stirrup binding not in place cause stirrup heap circle phenomenon.8 reinforcing bar of Φ is respectively set in node area quadrangle when construction and leads muscle
(length is identical as height of node), node area stirrup is welded on to lead by design spacing forms overall skeleton on the inside of muscle, then by bone
Frame, which is inserted in column, to be indulged muscle and is shelved on floor bottom mould, and beam steel is then worn, by tie tendons skeleton binding depth of section at node
On maximum beam.After binding, beam steel cage and tie tendons skeleton are integrally fallen into beam column template.To prevent from leading muscle position
It indulges muscle with column to conflict, node dimension of hoop reinforcement need to increase 10mm, lead muscle and deviate stirrup corner 50mm.
(7) whole heavy beam enters mould, using the 2 self-locking hauling capstans 9 installed on channel steel 8 at the top of trolley as steel reinforcement cage
Vertical lift device, suspends the first stull 13 in midair by 8mm wirerope (19*7), locks wirerope with snap ring.Then eave tile is unscrewed
Bolt 10 dismantles the second stull 14, while dismantling bottom bracing 17 and the second connecting screw of trolley lower part 6.Before beam steel cage enters mould, clearly
Working face sundries is managed, is blown off the sawdust in template with air pump, operator synchronizes in trolley two sides and shakes a liter self-locking pulley strand
Disk 9 makes steel wire tensioning holding force, and the lengthening nut 12 on harness cord screw rod 7 is rotated 180 °, avoids falling to steel reinforcement cage and causes to hinder
Hinder.Then self-locking hauling capstan 9 is turned round, bearing beam is used as by the first stull 13, steel reinforcement cage bulk settling is driven to enter mould.
(8) inspection of quality, transfer dolly after beam steel cage integrally enters mould, release wirerope, extract the first stull 13, peace out
The beam steel cage installed through entering next procedure after the assay was approved.The trolley component centralized collection assembling removed, transports reinforcing bar back and adds
Continue to be used in turn in workshop.
In conclusion having by means of above-mentioned technical proposal of the invention and loading transport, wear stirrup in advance, tied framework, hang down
Go straight up to drop, size adjustable, it is mobile flexible the features such as and function, set up falsework, live rehandling, repeatedly instead of traditional
It substitutes support, manually or mechanically lift the cumbersome technique that steel reinforcement cage enters mould, it is generally existing to solve current Cast-in-situ Beam reinforcement construction
The defects of operation sequence is complicated, speed of application is slow, high labor cost, working efficiency are low, reinforcing bar deformation, effectively prevent beam steel cage
Arcuation deformation, vertical muscle array pitch is exceeded, skew is tied up in stirrup leakage, the unequal common quality defect of interlamellar spacing is protected in beam side, it is ensured that cast-in-place joist steel
Muscle project installation quality.Tool trolley can be repeatedly used in turn, and simplify working procedure, mitigate labor intensity of workers, improve work efficiency,
A large amount of human resources and auxiliary material are saved, realization reduces cost, accelerates construction progress.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
