Description
Technical field
The utility model relates to a kind of cast-in-situ box girder high large span form bracing system, and particularly one crosses over operation speedway height cast-in-site box girder with large span form bracing system.
Background technology
Along with the development of China's economy, highway bridge and overhead road of city construction development are rapidly, often occur that overhead road of city, highway bridge cross over the problem of exist curves, namely different road, bridge are in identical plan-position and different locus, form multilevel traffic, but bridge type and quantity are extremely many, bridge width, turning radius are different, linear complicated and changeable.Be in the requirement reaching bridge construction diversified development, the more employing cast-in-situ box girder of top beam body.Cast-in-situ box girder has the complicated characteristic of construction, basement process, form bracing system are set up, pre-pressing bracket, template and reinforcement installation, each link influences each other, there is carelessness in arbitrary process, mishandling, all may there is mass defect, or cause serious quality accident, even destroy total.Wherein form bracing system is set up particularly important, traditional construction method and is adopted the mode of erection i iron and steel truss to ensure the normal operation of bottom speedway.No matter but the i iron set up on scaffold or steel truss are all difficult to the safety ensureing structure when crossing over the existing road and bridge of large span, and set up formwork system on i iron or steel truss, its supporting capacity is also difficult to ensure.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of cast-in-situ box girder high large span form bracing system, and structure is simple, and speed of application is fast.
To achieve these goals, the technical solution of the utility model is:
A kind of cast-in-situ box girder high large span form bracing system, primarily of scaffold, steel pipe column, steel truss, adjustable column, template composition, wherein steel truss is arranged on above original road and bridge, steel pipe column is provided with bracket, steel truss adopts high-strength bolt to be connected with steel pipe column by bracket, steel truss is provided with adjusting device, and scaffold is arranged in the both sides of original road and bridge.
Scaffold has the formwork support system of highway section cast-in-situ box girder and pier stud as non-leap, steel pipe column, steel truss and adjustable column are as the existing highway section cast-in-situ box girder formwork support system of leap, steel pipe column and steel truss are as the skeleton of Crossover phase formwork support system, and adjustable column is as the adjusting device of formwork height.
Aforesaid cast-in-situ box girder high large span form bracing system, described adjusting device is made up of adjustable column, leveling i iron and channel-section steel, and adjustable column is fixed between steel truss and leveling i iron, and leveling i iron and channel-section steel are welded and fixed.
Aforesaid cast-in-situ box girder high large span form bracing system, described scaffold is bowl fastening type steel pipe column, stabilized structure, effectively can ensure the structural stability of cast-in-situ box girder high form-tie assembly.
Aforesaid cast-in-situ box girder high large span form bracing system, the basis bottom described steel pipe column is concrete foundation, and is embedded in ground, ensures the intensity of steel tube column foundation.
Aforesaid cast-in-situ box girder high large span form bracing system, is provided with bridging between described steel pipe column, ensures the stability outside steel pipe column structure, avoids steel pipe column unstability.
Aforesaid cast-in-situ box girder high large span form bracing system, its described adjustable column is Height Adjustable steel pipe, meets the formwork requirement of top variable cross-section cast-in-situ box girder.
Aforesaid cast-in-situ box girder high large span form bracing system, described steel truss is provided with to be prevented pounding layer, avoids causing danger to bottom operation speedway during the construction of cast-in-situ box-beam of top.
the utility model has the following advantages and beneficial effect:
1, safety of structure is high, effectively can meet the normal operation of crossing over operation speedway.
2, structure is simple, and speed of application is fast, effectively can save the duration.
3, structure easy accessibility, reusable, has higher economic benefit.

Detailed description of the invention
The technical solution of the utility model is illustrated below with reference to drawings and Examples.
embodiment 1
Fig. 1 is easy adjusted type scaffold formwork system elevation, and as shown in Figure 1, in this embodiment, cast-in-situ box girder high large span form bracing system needs to cross over existing highway bridge 4.Form primarily of scaffold 1, steel pipe column 2, steel truss 8, adjustable column 6, template 17.Scaffold 1 is as the formwork braced structures of not Crossover phase cast-in-situ box girder 5 and pier stud 9, and cross over operation highway section formwork support system by steel pipe column 2 and steel truss 8 as support frame, steel pipe column 2 adopts high-strength bolt 12 to be connected with steel truss 8 by bracket 11.Steel truss 8 is provided with to be prevented pounding layer 13, ensures the safety of bottom operation speedway.
As shown in Figure 2, steel pipe column 2 is provided with steel tube column foundation 3, is provided with bridging 14 between steel pipe column, ensures the intensity of steel pipe column 2 in structure and the stability outside structure.Steel truss 8 is provided with leveling i iron 15, adjustable column 6, regulates i iron 7 and channel-section steel 16, as the formwork adjustment structure of variable cross-section cast-in-situ box girder 5.Adjustable column 6 is Height Adjustable steel pipes, as braced structures and the main adjustment structure of adjustment structure.
