Description
[technical field]
The utility model relates to Precast T-Beam web reinforcement moulding bed.
[background technology]
Prestressed T beam is in Current Engineering Construction process, existence due to presstressed reinforcing steel makes beam body own wt reduce to some extent, save steel, cross section reduces, span is larger, structural behaviour more, but in Precast T-Beam work progress, it is excessive or too small that the colligation of web reinforcement can produce vertical spacing, horizontal reinforcement can not ensure point-blank, the reinforcement location of variable cross-section accurately can not install location, can make to cause beam body concrete protective layer in later stage concreting process otherwise excessive or too small, standard construction requirement can not be met, simultaneously beam body variable cross-section reinforcement is located inaccurate meeting and is caused beam body to install inharmonious with matched template in work progress, cause problematic in work progress, beam body construction Quality Down.
Can show that prior art exists following shortcoming with existing construction technology according to causality reasoning:
1., on precast pedestal colligation web reinforcement, it is longer that steel bar meter semi-finished product are transported to transportation range on precast pedestal, and transport more difficult.
2., the web reinforcement spacing that goes out of colligation is difficult to control, and it is lower that the later stage measures concrete cover qualification rate.
3., on pedestal the bad accurate location determining beam body variable cross-section of colligation web reinforcement, the web reinforcement often causing colligation to go out exist after installation form dew muscle, or through secondary adjustment after qualified, waste of manpower.
4., manually, mechanical, material transfer carrying input is more, and efficiency of construction is low, causes unreasonable economically, and the steel bar quality of colligation is difficult to control.
5., colligation web reinforcement needs on precast pedestal time is longer, makes T girder prefabricated pedestal turnaround speed slow, long construction period.
[utility model content]
Main purpose of the present utility model is the positioning precision improving reinforcement construction in prestressed T beam construction.
Another object of the present utility model improves accuracy and the efficiency of prestressed T beam construction.
To achieve these goals, a kind of Precast T-Beam web reinforcement moulding bed is provided, comprise and multiple there is side vertical edge and bottom horizontal edge L-type support, L bracket is directly equidistantly arranged, the two ends of the horizontal edge of described multiple L-type support connect respectively by a foundation limit reinforcement welding, the position of multiple equal altitudes of the vertical edge of described L bracket is welded with the end of spacer bar, spacing between multiple height and positions of same vertical edge is corresponding with the spacing of the side reinforcement construction needing the T web reinforcing bar of constructing, the top of spacer bar is inclined upwardly and makes spacer bar and vertical edge form an accommodating angle.
This moulding bed also has optimizes structure as follows:
Described L-type support comprises the angle bar and side reinforcing bar with side vertical edge and bottom horizontal edge, the bottom of side reinforcing bar is welded with the side vertical edge of angle bar, the vertical edge of side iron and steel and angle bar forms the vertical edge of L-type support, and the base of angle bar forms the base of L-type support.
The diameter of described side reinforcing bar is 20mm.
The utility model compared with the existing technology, Precast T-Beam web reinforcement moulding bed is in work progress, accurately can locate the indirect size of vertical reinforcement, the straight problem of horizontal reinforcement, can production in enormous quantities be recycled simultaneously, make construction fast and accurate, the reduction of erection time, accelerate the construction speed of engineering, ensure Precast T-Beam construction quality.

[detailed description of the invention]
Below in conjunction with embodiment and accompanying drawing, the utility model is described further; be to be understood that embodiment and accompanying drawing are only not used in for explaining explanation and limit protection domain of the present utility model; the description about orientation in embodiment, as up, down, left, right, before and after is relative position instead of absolute position.
The structure of the Precast T-Beam web reinforcement moulding bed of the present embodiment as shown in Figure 1, comprise and multiple there is side vertical edge and bottom horizontal edge L-type support, L-type support comprises the angle bar and side reinforcing bar with side vertical edge and bottom horizontal edge, the bottom of side reinforcing bar is welded with the side vertical edge of angle bar, the diameter of side reinforcing bar is 20mm, the vertical edge of side iron and steel and angle bar forms the vertical edge of L-type support, the base of angle bar forms the base of L-type support, L bracket is directly equidistantly arranged, the two ends of the horizontal edge of described multiple L-type support connect respectively by a foundation limit reinforcement welding, the position of multiple equal altitudes of the vertical edge of described L bracket is welded with the end of spacer bar, spacing between multiple height and positions of same vertical edge is corresponding with the spacing of the side reinforcement construction needing the T web reinforcing bar of constructing, the top of spacer bar is inclined upwardly and makes spacer bar and vertical edge form an accommodating angle.
During construction, as shown in Figure 2, first carry out T beam base plate steel bar binding, according to the needs of the construction of T beam, by multiple T beam baseplate reinforcing bar interval colligation on the bottom horizontal edge of L bracket,
Shape of a hoof reinforcing bar binding
First to construct end muscle and the shape of a hoof reinforcing bar during construction of T web reinforcing bar binding, the spacing of shape of a hoof reinforcing bar is put according to the paint code made on the connecting reinforcement of bottom, carrying out colligation shape of a hoof reinforcing bar and can ensure that bar spacing meets design and code requirement according to the mark of working it out before, simultaneously for basis carried out by colligation vertical reinforcement below.
Transverse horizontal reinforcing bar binding
Transverse horizontal reinforcing bar binding has been come by the spacer bar that moulding bed has welded, spacer bar is inherently welded on above vertical φ 20mm plain bar, all positioning bars can ensure on one wire, and therefore transverse horizontal reinforcing bar is directly stuck on positioning bar and just can ensures that transverse horizontal reinforcing bar is straight.
Vertical reinforcement colligation
During vertical reinforcement colligation, shape of a hoof reinforcing bar and transverse horizontal muscle are all in place, the spacing of vertical reinforcement can well be controlled according to the shape of a hoof reinforcing bar of having good positioning before, simultaneously vertical reinforcement carries out colligation connection with already installed transverse horizontal reinforcing bar, and vertical reinforcement and shape of a hoof bar connecting and vertical reinforcement and transverse horizontal bar connecting can carry out colligation operation simultaneously.
Web reinforcement lifting after colligation completes
Web reinforcement after colligation completes carries out employing straddle truck machinery and lifts by crane, because spacer bar is deep in web reinforcement, and spacer bar is just in web reinforcement side, only need when therefore removing by lifting web reinforcement straddle truck to other side crawl, come off moulding bed spacer bar.
Lifting framework of steel reinforcement
Web reinforcement employing straddle truck can carry out lower one working procedure after rising and winching to precast pedestal;
It is exactly finally conventional construction procedure, Precast T-Beam web reinforcement moulding bed after colligation is risen and winches to precast pedestal, position the construction of the prestress pipe in web, installation end head formwork, installation termination prestressed anchor backing plate, side form installation, reinforcing, colligation roof steel bar, installation hogging moment prestress pipe, casting concrete.
