Embodiment 1
As shown in Figure 1, 2, 3, urban viaduct cantilever support system of setting a roof beam in place includes multiple concrete bearing platforms 1, concrete
Cushion cap 1 is arranged on ground 2 in two rows, and the line number of certain concrete bearing platform 1 is not limited to two rows, with specific reference to support column 3
Structural strength and the weight of precast beam 7 be determined.Ground 2 is to pass through the concrete after concrete hardening in the present embodiment
Ground, to improve the bearing capacity of support system.Concrete bearing platform 1 is the cuboid concrete pier as made of concreting, is applied
In advance by the predeterminated position installation template on 2 top of ground before work, then penetration concrete and bolt is inserted into concrete,
And it is fixed on the nut of bolt in concrete, the size of concrete bearing platform 1 is carried out with specific reference to the outer diameter and quantity of support column 3
It determines, further, in order to improve the precision of support system, the flatness control of 1 upper surface of concrete bearing platform is needed in 3.5mm
Within.
As shown in figure 4, support column 3 is the steel tube component of circular in cross-section, the both ends of support column 3 are provided with flange, prop up
The lower end of dagger 3 is bolted with concrete bearing platform 1.By setting flange, the installation and removal of support column 3 are facilitated,
Not only construction period is shortened, but also reduces operating expenses.Support column 3 is connected and composed by more 5 head and the tail of short steel pipes, short steel pipes 5
Both ends are also equipped with flange, to facilitate adjacent two short steel pipes 5 to be bolted.Since the length of every support column 3 can lead to
The quantity for crossing increase and decrease short steel pipes 5 is changed, therefore is wanted by the construction that the length of change support column 3 can meet different engineerings
It asks, after an engineering use, Other Engineering construction can be used for by maintaining it, without customizing support column 3 again, because
This can substantially reduce the operating expenses of engineering, shorten construction period.In addition, the diameter of short steel pipes 5 is 609mm, diameter 609mm
Short steel pipes 5 be common steel pipe in engineering, the short steel pipes 5 in different engineering constructions are used interchangeably, to further decrease
The operating expenses of engineering.
Sling by loop wheel machine for carrying precast beam 7, when construction precast beam carrier 4 be set up in prefabricated joist support by precast beam 7
On carrier 4, precast beam carrier 4 includes two girders 41 and Duo Gen distribution beam 42, and the quantity of certain girder 41 is not limited to
Two, two girders 41 are respectively correspondingly set up in the upper end of every row support column 3, and distribution beam 42 is then set up in the top of girder 41
And it is vertical with the trend of girder 41.The length of distribution beam 42 is greater than the width of 7 bottom of precast beam, provides for precast beam 7 certain
Mobile space.
The urban viaduct cantilever of the present embodiment support system of setting a roof beam in place is supported by using support column 3, simplifies branch
The structure of frame system has the advantages that installation and removal convenience, short construction period, bearing capacity are high and highly-safe.
Embodiment 2
The present embodiment based on embodiment 1, the present embodiment difference from example 1 is that, it is main in the present embodiment
Beam 41 and distribution beam 42 are H profile steel, since H profile steel is common steel in engineering, can be with the H on Other Engineering
Fashioned iron is used interchangeably, and is mounted and dismounted conveniently, therefore can further decrease the operating expenses of engineering.In addition, in the present embodiment
Adjacent two support columns 3 are connected by connecting rod 8, and by being welded to connect, adjacent two support columns 3 are logical for connecting rod 8 and support column 3
The connection of connecting rod 8 is crossed, so that support system in the present embodiment is compared to the support system in embodiment 1, structural strength and is held
Power is carried to be greatly enhanced.
Application method, before construction, the predetermined position casting concrete cushion cap 1 on 2 top of ground between two bridge piers 6.It applies
Working hour, the lower end of support column 3 and concrete bearing platform 1 were bolted, so that support column 3 is fixed on concrete bearing platform 1
Top, adjacent two support columns 3 are connected by connecting rod 8, precast beam carrier 4 are set up in the upper end of support column 3, then lead to
It crosses the top that precast beam 7 is set up in precast beam carrier 4 by loop wheel machine, and is connect with bridge pier 6, bent cap etc..Again will after construction
Precast beam carrier 4 and support column 3, which disassemble, to be saved for future use, at this time the weight of overpass all by bridge pier 6 into
Row carrying.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
