Description
Technical field
The utility model relates to the prefabricated assembled technical field of construction of cast in place frame column steel reinforcement cage, it particularly relates to one
The kind prefabricated assembled constructing device of cast in place frame column steel reinforcement cage.
Background technique
In conventional at present cast in place frame, Frame _ Shear Wall Structure system, the production of reinforced bar engineering and it is mounted on building
Occupy very big ratio in construction, no matter fee of material, labour cost or the time cost of consumption, for the economy of monolithic architecture
Benefit is most important.Meanwhile reinforced bar engineering and the processes such as template is installed, water power is pre-buried, structural concrete pours are interted mutually, mutually
To restrict, and traditional construction technique biases toward field operation, and labor intensity of workers is big, technical level is irregular, and each single item is applied
It is compact whether the linking of work link is coordinated, and directly affects safety, quality, working efficiency and the construction cost of Structural Engineering.
With the popularization increasingly of assembled architecture, concrete and reinforcement component prefabricating technique gradually form building trade reform
A large amount of works on the spot are transferred to processing factory's operation by the new industry of upgrading, element precast technique, using industrialization, it is standardized
Manufacture is produced in batches, and a large amount of human resources can be saved, effectively reduction construction period, the peace of lifting construction overall process
Entirely, quality and efficiency.
Due to current China's economic structure and the lack of uniformity of industrial system, the cooked mode of assembled architecture industrial chain is still
Do not perfect, traditional cast in place frame, Frame _ Shear Wall Structure are still widely applied, but the advantage of reinforcement component prefabricating technique
Be difficult in full cast-in-place structural be effectively played, the especially reinforcement installation of cast in place frame column, due to steel concrete supporting
Accuracy requirement, steel reinforcement cage is tied up installation in advance and is difficult to realize, and other than basal layer, ± 0 is still used manually at present with upper prop reinforcing bar
It is installed by root, largely relies on execute-in-place.In traditional handicraft, the construction of column steel reinforcement cage generally first all covers column tie-bar stretches in lower layer
Column out is indulged on muscle, then by the long vertical muscle of piece-root grafting, draws stirrup spacing line on vertical muscle, then the stirrup packaged is gradually put down upwards
It moves, is from top to bottom bound by root.There is many defects, specific manifestations for this construction method are as follows:
1, after the reinforcing bar semi-finished product vertical transport to floor of backstage production, artificial rehandling is needed, scene needs a large amount of
Underworker consumes huge cost of labor.
2, artificial setting is needed when indulging muscle spreading, by root connection, large labor intensity, and vertical muscle top generally lack enough
Strutting means indulges the flexible deformation of muscle.
3, time-consuming and laborious when the stirrup that vertical muscle lower part packages in advance moves up, need more people to cooperate, up and down repeatedly transmitting, work
Low efficiency, speed of application is slow, and artificial investment increases.
4, very difficult by vertical muscle straight thread connecting sleeve when stirrup moves up, especially column section and vertical muscle is relatively large in diameter
When, compound stirrup is criss-cross, and quantity is various, and connection sleeve outer diameter is more than in stirrup away from stirrup is difficult to smoothly above mention, Zhi Nengkuo
In stirrup away from or the curved sled of hardness be forced through, cause stirrup to deform.
5, it is required according to job specfication, stirrup corner and vertical muscle intersection point should buckle binding using twining, and guarantee stirrup and vertical muscle
It is vertical and closely connected, and field worker be it is laborsaving seek quickness, mostly use it is easy along button binding, if stirrup deform be difficult to it is completely extensive
Shape is restored, corner cannot abut and hook vertical muscle, main reinforcement protective layer is caused to be unsatisfactory for design requirement, and change reinforcing bar and tying
Stress in structure reduces the bearing capacity and anti-seismic performance of component.
6, lack the mature technology that reinforcing bar precasting process is applied to cast-in-place structural at present, continue to use conventional method, technology always
It updates slowly, the operation level and sense of responsibility of skilled worker is irregular, and quality management is there are bottleneck, bar bender in cast-in-place structural
The defect of journey conventional construction method is by long-term existence.
For the problems in the relevant technologies, currently no effective solution has been proposed.
Utility model content
For above-mentioned technical problem in the related technology, the utility model proposes a kind of prefabricated dresses of cast in place frame column steel reinforcement cage
With formula constructing device, traditional artificial rehandling can be replaced, vertical muscle is erect by root, gradually moves up the cumbersome work for being distributed stirrup
Skill, solves that the generally existing operation sequence of current frame column reinforcement construction is complicated, speed of application is slow, high labor cost, work effect
The defects of rate is low, reinforcing bar deforms, fundamentally guarantees frame column reinforcement installation quality.Column reinforcing bar can be prefabricated into advance in processing space
Cage, overall assembled lifting, live fast binding molding.It can repeatedly be used in turn, simplify working procedure, improve work efficiency, save
Human resources, realization reduce cost, accelerate construction progress.
To realize the above-mentioned technical purpose, the technical solution of the utility model is achieved in that
