Description
Technical field
The present invention relates to science of bridge building fields, are especially the reinforcing bar moulding bed and construction method of a kind of construction bridges T beam.
Background technique
T beam is one kind of science of bridge building central sill, is made of the web of the top plate on top and lower part, cross section be it is T-shaped, because
And it gains the name.It is convenient for statement, introduce two orientation concepts, the length direction of the length direction of T beam also bridge be it is longitudinal,
The width direction of T beam also bridge width direction be laterally.
The construction method of the construction of bridge T beam of the prior art is first to bind web reinforcement net, props up vertical web side template, sets up and fall
Ground scaffold operating platform binds roof steel bar net on the operational platform, and installs the backform board mount of semi-finished product formula, and
Roof plate template is set up on backform board mount, then the concrete of formed by integrally casting web and top plate, last tensioning maintenance.
The construction method of the construction of bridge T beam of the prior art suffers from the drawback that the process of binding roof steel bar net belongs to high-altitude
Operation, when the assembling reinforcement of high-altitude, operating difficulties, each reinforcing bar contraposition inaccuracy, the steel mesh bound out is of poor quality, time-consuming and laborious,
Construction speed is slow, long in time limit, quality safety is uncontrollable, moreover, high-altitude binding needs up to set up design of coupler scaffold from ground
Operating platform, this just further increases the consumable quantity of steel tube fastener, further increases labor intensity, schedule delays.
Summary of the invention
The invention solves a technical problem be to provide it is a kind of can make operating process it is simple and convenient, it is time saving and energy saving, top
Each reinforcement location of plate steel mesh is accurate, roof steel bar net is high-quality, can accelerate construction progress, shorten the construction period, securely and reliably
Construction bridges T beam reinforcing bar moulding bed.
The technical solution of the invention is as follows, provides a kind of reinforcing bar moulding bed of construction bridges T beam with flowering structure, it is wrapped
The Y shape steelframe being parallel to each other and the main girder steel of the one-to-one bottom steelframe of Y shape steelframe and longitudinal direction of longitudinally spaced laying are included, often
A Y shape steelframe is fixed on corresponding bottom steelframe, and longitudinal main girder steel connects whole Y shape steelframes with bottom steelframe integral；Each Y
It is equipped with positioning plate and lower positioning plate on two cant beams of shaped steel frame, is equipped with opening upwards on upper positioning plate and lower positioning plate
Locating notch, longitudinal main girder steel are equipped with fishback, and a main girder steel in longitudinal direction is fixed with parallel with longitudinal main girder steel through attachment beam
Abutment plate.
Another technical problem to be solved by the present invention is that providing, a kind of operating process is simple and convenient, time saving and energy saving, top plate steel
Each reinforcement location of muscle net is accurate, roof steel bar net is high-quality, can accelerate construction progress, shorten the construction period, securely and reliably, and
Web reinforcement net and roof steel bar net or even web and top plate be firmly combined using reinforcing bar moulding bed of the invention come construction bridges T
The method of beam.
Another technical solution of the invention be to provide it is a kind of using reinforcing bar moulding bed of the invention come construction bridges T beam
Method, it includes following construction procedure:
A, web reinforcement net is bound, and is fixed with vertical cable wire in the online welded sleeve of web reinforcement, sleeve, and is vertical
Web reinforcement net is stretched out on cable wire top, then props up vertical web side template；
B, roof steel bar net is bound on reinforcing bar moulding bed, wherein by the every longitudinal reinforcement of a upper row for roof steel bar net
It is shelved in the locating notch of the upper positioning plate of each Y shape steelframe, every longitudinal reinforcement of the next row of roof steel bar net is put
It sets in the locating notch of the lower positioning plate of each Y shape steelframe, the per pass lateral tie of roof steel bar net is stuck in fishback two
In the gap of adjacent fingers, and by the side of per pass lateral tie in abutment plate against alignment；
C, the backform board mount of semi-finished product is installed, and sets up roof plate template on backform board mount, then will be bound
The lifting of roof steel bar net it is in place, and by vertical cable wire top stretch out the part of web reinforcement net and roof steel bar net bind it is solid
It is fixed；
D, the concrete of formed by integrally casting web and top plate, last tensioning maintenance.
The reinforcing bar moulding bed of construction bridges T beam of the present invention and using the reinforcing bar moulding bed come the method for construction bridges T beam and existing
There is technology to compare, there is following remarkable advantage and beneficial effect.
Firstly, since reinforcing bar moulding bed is placed in ground, so binding roof steel bar net no longer needs high altitude operation, this
With regard to convenient process of binding, the risk of operation is reduced, and Ground Operation can ensure that each reinforcing bar contraposition is accurate, improve behaviour
Make the quality constructed, and without up setting up steel tube fastener formula operating platform from ground, further convenient operation reduces labour
Intensity is accelerated speed of application, is shortened the construction period；When especially with reinforcing bar moulding bed assembling reinforcement net, whole upper row longitudinal direction steel
Muscle is all shelved in the locating notch of upper positioning plate of Y shape reinforcing bar, and the positioning that next placing of reinforcement is then shelved on lower positioning plate lacks
In mouthful, and per pass lateral tie is then stuck in the gap of two comb teeth of fishback, and the side of whole lateral ties all with abutment plate
Alignment is pushed against, so, each reinforcing bar, the stirrup of steel mesh all align accurately, which improves the binding quality of steel mesh, into
And improve the integral strength of last molding T beam；Due also to cable wire is fixed in web reinforcement net, and cable wire upper end and top
The binding of plate steel mesh, therefore the connection and globality of web reinforcement net and roof steel bar net are strengthened, effectively increase the secured of T beam
Degree and stability.
