Technical field
The utility model relates to the bridge span erecting machine field, and particularly wherein U type concrete beam is hung operation platform.
Background technology
In building High-speed Railway Bridges, urban track traffic bridge, U type concrete beam application quantity enlarges day by day.At present, for bridge formation, the carrying out that pier roof rail prestressed stretch-draw, grouting and roof beam structure are set to operations such as a rear suspension bar dismounting, support grouting all needs operation platform.Present most widely used method is the scene formula platform that scaffolds erecting, but this is not only time-consuming but also be subject to foundation condition, if run into the rivers pool, also will spend significant cost that ground is carried out landfill, exhausts the people and drains the treasury very much.
Summary of the invention
The utility model technical problem to be solved provides a kind of U type concrete beam and hangs operation platform, can ingeniously utilize the features of shape of U type concrete beam, forms the movable prefabricated platform that does not rely on ground, practices thrift engineering time and cost.For this reason, the utility model adopts following technical scheme: it is provided with the hanging hang structure that colludes that cooperates with U type concrete beam web upper end, and the said hanging hang structure that colludes is held said web upper end tightly through roller; Said operation platform also comprises pillar construction, working platform, said pillar construction with collude hanging hang structure and be connected, working platform is connected with pillar construction; Said working platform, pillar construction and collude that hanging hang structure forms can be around the suspended structure of U type concrete beam web and pier roof rail side and bottom, said working platform is under the pier roof rail.
On the basis of adopting technique scheme, the utility model also can adopt following further technical scheme:
Said working platform is divided into inboard canned paragraph and outside active segment, and inboard canned paragraph is connected with pillar construction, and outside active segment and inboard canned paragraph are hinged, and the berm width of inboard canned paragraph is less than the spacing between column and the bridge pier pier shaft.
The upper end of said column also connects second platform, and said operation platform is provided with from the inner cat ladder of second platform to U type concrete beam, colludes the below that hanging hang structure is in second platform.
The said running roller that colludes hanging hang structure comprises left and right sides roller, upper roller and bottom roller, and the web upper end has inside colluding and hangs the edge of a wing and cooperate with said left wheel or right roller, upper roller and bottom roller.
The adjustable positions of left and right sides roller and bottom roller is whole.
Said working platform is connected by section bar with pillar construction builds.
Working platform is provided with the railing of rotatable folding; Owing to adopt the technical scheme of the utility model; The utility model can ingeniously utilize the features of shape of U type concrete beam, forms the movable prefabricated platform that does not rely on ground, to place under the bridge and the basic no requirement (NR) of headroom; On the operation platform of the utility model, can carry out the operation that pier roof rail prestressed stretch-draw, grouting and U type concrete beam set up the operations such as rear suspension bar dismounting, support grouting that put in place; The utility model can be practiced thrift engineering time and cost.
Description of drawings
Fig. 1 is operation platform that the utility model the provided sketch map when in running order.
Sketch map when Fig. 2 is in mobile status for operation platform that the utility model provided.
The specific embodiment
With reference to accompanying drawing.The utility model is provided with the hanging hang structure that colludes that cooperates with web 101 upper ends of U type concrete beam 100, and the said hanging hang structure that colludes is held said web upper end tightly through roller; Said operation platform also comprises pillar construction 2, working platform 3, said pillar construction 2 with collude hanging hang structure and be connected, working platform 3 is connected with pillar construction 2; Said working platform 3, pillar construction and collude that hanging hang structure forms can be around the suspended structure of U type concrete beam web 101 and pier roof rail 200 sides and bottom, as shown in Figure 1, said working platform is under the pier roof rail.
Pillar construction is the connecting elements that colludes 3 of hanging hang structure and working platformes, the double hanging point of stretch-draw jack and staff's the last lower channel done.
Said working platform is divided into inboard canned paragraph 31 and outside active segment 32, and inboard canned paragraph 31 is connected with pillar construction 2, and outside active segment 32 and inboard canned paragraph 31 are hinged, and the berm width of inboard canned paragraph is less than the spacing between column and the bridge pier pier shaft.Like this, can guarantee not hinder working platform to move, make working platform can make working platform wide as far as possible through under the prerequisite of pier shaft 201, the operating personnel that are more convenient for carry out associative operation.
The upper end of said column also connects second platform 4, and said operation platform is provided with from the inner cat ladder 5 of second platform, 4 to U type concrete beam, colludes the below that hanging hang structure is in second platform.Like this, the utility model also becomes the inside and outside instrument of U type concrete beam of linking up.
The said running roller that colludes hanging hang structure comprises left and right sides roller 61,62, upper roller 63 and bottom roller 64, and the web upper end has inside colluding and hangs the edge of a wing 102 and cooperate with said left wheel or right roller, upper roller and bottom roller.The adjustable positions of left and right sides roller and bottom roller is whole, such as connecting through modes such as bolt, slotted holes, thereby position, the scalable left and right sides, upper-lower position, further guarantee and the web upper end between the gap suitable.
Said working platform is connected by section bar with pillar construction builds, in light weight.
