Description
Technical field
The present invention relates to the realm of building construction, specially a kind of Precast T-Beam web reinforcement binding auxiliary moulding bed construction.
Background technique
With the economic rapid growth in China, southwest creates highway and is increasing, because southwest mountainous region is more
Mountain shape is steeper, and for freeway bridge tunnel than usually higher, highway often selects the side of Precast T-Beam lifting when across mountain valley
Formula construction.
The reinforcing bar of Precast T-Beam web is densely distributed, substantial amounts, and during T is beam prefabricated, the binding of reinforcing bar is to restrict
Duration and the critical process for influencing quality.
The low efficiency of current construction method construction method Precast T-Beam reinforcing bar binding, labor intensity of workers is high, construct into
Degree is slow, and the construction period is long；The binding of reinforcing bar is of low quality, spacing and different design, out of plumb after often there is reinforcing bar binding
Etc. many common quality problems, disposable acceptable quality level is low, and input cost is high, and construction cost is high.
Summary of the invention
Precast T-Beam reinforcing bar binding auxiliary moulding bed is made according to design drawing the present invention provides a kind of, auxiliary moulding bed is main
It is made of body frame, reinforcing bar locating slot, hanger, is mainly used to position T web and diaphragm plate reinforcing bar.It is bound in Precast T-Beam reinforcing bar
When, using body frame and the positioning of reinforcing bar locating slot and support webs reinforcing bar (including horseshoe reinforcing bar, vertical web reinforcement), utilize hanger
Positioning and support diaphragm plate reinforcing bar, so that it is determined that spacer bar spacing, improving the disposable qualification rate of steel corrosion quantity, improving worker and apply
The Precast T-Beam web reinforcement binding auxiliary moulding bed construction of work efficiency rate.
The object of the present invention is achieved like this: Precast T-Beam web reinforcement binding auxiliary moulding bed construction, comprising:
A assists moulding bed to prepare
Preparation auxiliary moulding bed body frame each section of A1 auxiliary moulding bed body frame is formed by steel pipe and reinforcement welding；
A2 assist moulding bed reinforcing bar locating slot combination design drawing, design the reinforcing bar locating slot for meeting bar spacing modulus and
Hanger, auxiliary moulding bed reinforcing bar locating slot are formed using steel processing and fabricating, are installed on pedestal, the aperture position of locating slot must
Must be accurate, it can come into operation after qualified by inspection；
The preparation hanger suspending of A3 hanger is fixed on body frame, is welded using seamless steel HPB steel bar meter；
Awning is welded in body frame topmost by the preparation of A4 awning；
Horseshoe muscle binding in the lower part B is bound using reinforcing bar locating slot spacer bar spacing, is controlled by way of bracing wire
The lateral position of vertical web reinforcement；
The vertical web reinforcement binding of C is bound using reinforcing bar locating slot with the reinforcing bar positioning spacing bound, vertically
Before web reinforcement binding, the lateral position of vertical web reinforcement is controlled by way of bracing wire；
D diaphragm plate reinforcing bar binds diaphragm plate reinforcing bar using hanger progress muscle binding, and when binding needs to pay attention to different-diameter
Position where diaphragm plate reinforcing bar
The binding of E longitudinal reinforcement carries out the binding of longitudinal reinforcement after completing the positioning binding of vertical web reinforcement,
F examination, handling
Further, in step A1, the longitudinal steel pipe and supporting steel pipe of body frame use 60 × 4 seamless steel pipe of Φ, body frame
Truss bars and hanging ring use the HPB reinforcement fabrication of diameter 10mm.Body frame must assure that enough intensity, rigidity and stability,
The position of hanging ring must be accurate, can come into operation after qualification by inspection of marching into the arena.
Further, in step A2, the reinforcing bar locating slot is mounted on pedestal, and pedestal concrete strength reaches must
It must specification.
Further, in step A3, the hanger is using the welding of the HPB steel bar meter of 60 × 4 seamless steel pipe of Φ and 8mm
It forms, welding position of the reinforcing bar on steel pipe must be accurate, can come into operation after qualified by inspection.
Further, in step B, bottom longitudinal reinforcement is placed after horseshoe reinforcing bar in lower part is first installed, then carry out horseshoe reinforcing bar
With the binding of longitudinal reinforcement；Before carrying out the binding of horseshoe reinforcing bar and longitudinal reinforcement, bar spacing is checked, it is wrong timely
Adjustment.
Further, in step C, T beam both ends end portion vertical reinforcement is needed from the bottom plate longitudinal reinforcement bound
Under be inserted in, be then put into the reinforcing bar locating slot one by one；The vertical web reinforcement of T beam during installation, close by vertical web reinforcement
Ring will be inserted in lifting connecting steel wire ropes, and lifting connecting steel wire ropes penetrate body frame hanging ring before vertical reinforcement binding.
Further, in step E, when binding should be noted is inserted in every square meter much not 4 circles in advance on longitudinal reinforcement
Minimum Concrete Protective Coating Thickness controls cushion block, and cushion block presses quincuncial arrangement and fixation.
Further, in step E, the T web and diaphragm plate reinforcing bar bound is inspected by random samples, it is ensured that binding is secured；It utilizes
Body frame carries out T web and the handling of diaphragm plate reinforcing bar, it is noted that safety, handling relevant regulations meet relevant safety regulations when handling
It is required that；It needs to penetrate bellows before handling, simultaneously fixation；After being hoisted to beam making bench, T beam steel position is carried out again
It examines, underproof place re-starts adjustment, after self-test is qualified, asks Party A, management to check and accept reinforcing bar, installs mould after acceptance(check)
T beam roof steel bar is bound after plate, template installation.
The present invention can effectively improve the efficiency of Precast T-Beam reinforcing bar binding, be effectively reduced labor intensity of workers, quickening construct into
Degree saves the construction period；
The binding quality for effectively improving reinforcing bar, the spacing and different design, out of plumb etc. after avoiding reinforcing bar binding are many
Common quality problems improve disposable acceptable quality level；
The present invention is primary investment, is used in turn often, can be effectively reduced construction cost from many aspects.
Positive beneficial effect: due to use of the invention, improving the quality of T beam steel bar colligation, to improve T joist steel
Muscle binds disposable acceptable quality level, reduces trimming of doing over again, and saves human resources, and then not only reduce required wave of doing over again
The time of expense can also establish flat image, to obtain the approval of management, owner, Quality Supervision Station and personages of various circles of society.
Expense, duration are carried out to score by taking the binding of a piece of 30m Precast T-Beam reinforcing bar (by 8 worker's bindings for radix) as an example
Analysis analyzes result as shown in following table 10.1.
The a piece of 30mT beam steel bar colligation expense of table 1, duration comparative analysis table
As can be seen from the above table, a piece of 30 meters of T beam steel bar colligations, if labour cost about 800 can be saved using auxiliary moulding bed
Member, the duration about 0.5 day.It can be seen that the present invention can generate very considerable economic benefit.
