Description
Technical field
The utility model relates to a kind of bridge reinforcement positioner, specifically a kind of bridge curtain board steel bar positioning frame.
Background technology
Bridge curtain board is a kind of bridge floor engineering concrete component, adopts Prefabrication.In order to attractive in appearance, shield profile design is the irregular contour of band circular arc camber.In addition, the elongated employing shake table of prefabricated shield concreting vibrates.So the fixing difficult problem just becoming prefabricated quality control of shield framework of steel reinforcement, the method for traditional assembling reinforcement protective layer cushion block is adopted just to be difficult to ensure the accurate location of framework of steel reinforcement.
Summary of the invention
The utility model is difficult to the problem of the accurate location ensureing framework of steel reinforcement in order to solve, shield framework of steel reinforcement is not shifted when concreting, ensures that position is accurate, provides bridge curtain board steel bar positioning frame.
The utility model takes following technical scheme: a kind of bridge curtain board steel bar positioning frame, comprise and be arranged on angle iron frame on the upside of shield mould of plastics and two round steel backstays, angle iron frame has two symmetrical notches, in notch, card has round steel backstay, round steel backstay is welded with two and may be stuck in angle iron frame inner vertical in shaft short round steel pin I straight down, round steel backstay is also welded with two and can fixes framework of steel reinforcement position perpendicular to shaft short round steel pin II straight up.
Described angle iron frame comprises parallel and symmetrically arranged two top angle steel and parallel and symmetrically arranged two bottom angle steel, notch is arranged on the edge of a wing of top angle steel, two bottom angle steel are welded to connect the downside at angle steel two ends, top respectively by frame iron, rectangular frame is made in top angle steel and the welding of bottom angle steel, and bight, angle steel two ends, bottom is respectively welded with a dihedral baffle plate.
Described round steel backstay is L shape, and the long limit size of round steel backstay is greater than angle iron frame, and the minor face of round steel backstay is handle.
After shield framework of steel reinforcement puts into template, angle iron frame centering be placed on shield mould, dihedral baffle-plate-sleeve is stuck in shield mould of plastics bight suitable for reading.Then framework of steel reinforcement is mentioned a little height, pass upper placing of reinforcement from side by round steel backstay, when pin arrives mould inner edge to shaft, round steel backstay is put into notch.Then hold minor face handle 90-degree rotation, make two the short round steel pin I in outside be stuck in angle iron frame inner edge, two the short round steel pin II in inner side are stuck in outside framework of steel reinforcement.Now, framework of steel reinforcement position is fixed, can casting concrete.
Complete in concreting, after maintenance to demoulding strength, take off locating rack together with component, again have enough to meet the need use.
Compared with prior art, the utility model has following beneficial effect:
1, novel, the pioneering shield steel bar positioning frame that adopts substitutes traditional assembling reinforcement protective layer cushion block method, fixes shield reinforcement location, solves a difficult problem for the reinforcing bar location of this abnormity concrete member of shield, ensure that the construction quality of shield.
2, shield steel bar positioning frame is skillfully constructed.Adopt the mode of angle iron frame and the combination of round steel backstay dexterously, structure is simple, easy to operate, accurate positioning.
3, shield steel bar positioning frame achieves and fixes the three-dimensional of framework of steel reinforcement.Angle iron frame is stuck in template by dihedral baffle-plate-sleeve, ensures that the position of locating rack own is fixed.And the upper-lower position of framework of steel reinforcement, arranged by the height of angle iron frame and backstay and ensure.The front and back position of framework of steel reinforcement is ensured by the pin on backstay.The right position of framework of steel reinforcement, is embedded in by backstay in the notch of angle iron frame and ensures.Therefore framework of steel reinforcement really can be kept not to be shifted when concreting.So result of use is remarkable.
4, the material that shield steel bar positioning frame uses is all common iron conventional on construction site, and cost is low.And can use be had enough to meet the need.Save a large amount of cushion block of concrete bar protective layer in addition, therefore apply and can reduce engineering cost, obtain good economic benefit.

Detailed description of the invention
A kind of bridge curtain board steel bar positioning frame, comprises and is arranged on angle iron frame 1 on the upside of shield mould of plastics and two round steel backstays 5.As shown in Figure 1, angle iron frame 1 has two symmetrical notches 2, in notch 2, card has round steel backstay 5.As shown in Figure 4, round steel backstay 5 is welded with two and may be stuck in angle iron frame inner vertical in shaft short round steel pin I6 straight down, round steel backstay 5 is also welded with two and can fixes framework of steel reinforcement position perpendicular to shaft short round steel pin II7 straight up.
As shown in Figure 2,3, described angle iron frame 1 comprises parallel and symmetrically arranged two top angle steel 1.1 and parallel and symmetrically arranged two bottom angle steel 1.2, notch 2 is arranged on the edge of a wing of top angle steel 1.1, two bottom angle steel 1.2 are welded to connect the downside at top angle steel 1.1 two ends respectively by frame iron 3, rectangular frame is made in top angle steel 1.1 and bottom angle steel 1.2 welding, and angle steel 1.2 liang of vertex angle parts in bottom are respectively welded with a dihedral baffle plate 4.
Described round steel backstay 5 is L shape, and the long limit size of round steel backstay is greater than angle iron frame, and the minor face of round steel backstay is handle.
As shown in Figure 5, rectangle made by angle iron frame four angle steel and Plate Welding.Two top angle steel frame brandreths that little block plate is made are welded on the angle steel of bottom, and height is determined according to framework of steel reinforcement height.Bight, angle steel two ends, bottom is respectively welded with the dihedral baffle plate that a steel plate is made.The internal orifice size of framework and dihedral baffle plate presses the appearance and size making suitable for reading of shield mould of plastics.Dihedral baffle plate tightly can be stuck in the bight suitable for reading of shield mould of plastics.On the angle steel edge of a wing, top, corresponding framework of steel reinforcement endothelium position has two relative notches, and width of rebate is with the diameter of round steel backstay.The degree of depth of notch is determined according to the height and position of shield reinforcing bar.Round steel backstay round steel is bent into L shape.The long limit size of bar is greater than angle iron frame.The minor face of bar is handle, and length so that hold is advisable.On the long limit of bar, appropriate location is welded with 4 short round steel pin I perpendicular to shaft and short round steel pin II, and wherein two are used for being stuck in inside angle iron frame, and two are used for fixing framework of steel reinforcement position.
