Embodiment
The present invention is described in further details with specific embodiment below in conjunction with the accompanying drawings.As shown in figure 1, a kind of bridge pier
Post reinforcement installation crosshead, including two independent steel pipe frames 2, the cross section of steel pipe frame 2 are U-shaped, during combination, two steel pipes
The free end face of the U-shaped of frame 2 is corresponding to be surrounded on the periphery of bridge pier column 1, and two corresponding free end faces are detained by combining
Part 4 is fixedly connected.Steel pipe frame is welded using 57 × 3mm of φ steel pipe combinations.
The combination of two steel pipe frame preferences is as shown in Fig. 2 assembly buckle 4 includes fastener body 42, fastener body
42 left and right ends respectively set a combination neck 43；Connection cross bar 21, corresponding freedom are provided with the free end face of steel pipe frame 2
Two connection cross bars 21 on end face are fastened in the combination neck 43 of the same left and right ends of fastener body 42 respectively.Assembly buckle
4 are formed using Φ 28 reinforcement welding, and fastener body 42 is welded with the rectangular frame of reinforcing bar diagonal brace 41, wherein fastener sheet for centre
Using patch angle full weld between body 42 and the combination neck 43 of projection.Can be with according to the height of steel pipe frame, on corresponding free end face
Multigroup connection cross bar 21 and assembly buckle 4 are set, to ensure the firm of connection.The combination, is not only simple in structure, and connection is steady
Gu, installing/dismounting is also more convenient.
The structure and size of steel pipe frame 2 can be set according to the shape and size of the cross section of bridge pier column 1 in construction.If beam
The cross section of pier stud 1 is circle, then steel pipe frame 2 need to be set to the semicircle arcuation of corresponding size, if the cross section of beam pier stud 1 is rectangle,
Then steel pipe frame 2, which should be set to structure, includes one long frame side 22 and two side racks 23 for being vertically fixed on the long two ends of frame side 22.
Exemplified by reinforcement installation crosshead for cross section for the bridge pier column of rectangle, the concrete structure of above-mentioned steel pipe frame
As shown in figure 3, long frame side 22 includes outrigger and internal frame, outrigger is that multiple column steel pipes 25 and multiple cross bar steel pipes 24 intersect
The gratings of composition is fixedly connected with, internal frame is identical with outrigger structure, and is fixedly connected between internal frame and outrigger by support rail 27；
The side rack 23 is identical with the long structure of frame side 22.
Wherein, the intersection of column steel pipe 25 and cross bar steel pipe 24 is provided with the welding groove being mutually twisted.In steel during welding
Pipe junction eliminates 1/3 as welding groove, is allowed to be close to firm welding.
For convenience of lift, can on steel pipe frame 2 welding hanging ring 5, suspension ring use the reinforcing bars of Q235 φ 16, per single steel pipe frame use
4 suspension ring, are allowed to lifting and are steadily easily installed in place, suspension ring weld answers two-sided firm welding.
The bottom of steel pipe frame 2 is fixedly connected with angle cleat 26, can be using the welding of the angle steel of L100 × 10.It is welded on internal frame
φ 20 bolt hole is opened up on angle cleat, so that steel pipe frame is bolted to connection with template.
Welding anti-slip steel thickness of slab 2.5mm is set up on every layer operation platform of crosshead, berm width is not less than 60cm, inner side
Steel cat ladder is hung to be easy to pass through above and below workmen.
In use, can in advance on construction ground outside steel pipe frame is welded, can not so be limited by construction site, operate
It is more convenient and simple.During construction, it is fixedly connected after two steel pipe frames are lifted in place with tower crane or automobile first with assembly buckle,
It need to only be placed on one side on reserved section template operation platform, another side and reserved section template bolt connection.After steel pipe frame is installed
Close mesh protection network is completely hung in surrounding, protection network should be close to surrounding.Dismantling operation frame after the completion of the construction of this section reinforcement installation is treated, then is pacified
Fill combined steel formwork casting concrete.The steel pipe frame disassembled can also repeat recycle, greatly reduce operational procedure and
Construction cost.
