Brief description of the drawings
Fig. 1 is the structural representation of steel box beam erection support meanss in the embodiment of the present application；
Wherein, 1- steel pipe columns, 2- fixed mounts, 3- pedestals, the rearmounted chemical anchor bolts of 4-, 5- reinforcements, 6- connecting plates, 7- is adjustable
Section bracket.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, but implementation method of the present utility model is not limited to
This.
Embodiment：
The simple adjustable supports system of large-span steel pile equipment Quick Release, as shown in figure 1, including being provided with pre-embedded steel slab in some
Pedestal 3, a support frame is fixed with each pedestal 3, support frame as described above is removably connected up and down successively by multiple standard knots
Connect and form, the standard knot includes at least three vertically and the steel pipe column 1 of equal length, adjacent two steel pipe column in single standard knot
Connected by fixed mount 2 between 1, the quantity of steel pipe column 1 on same support frame in all standard knots is identical and position is corresponding；Most
The lower end of steel pipe column 1 in lower floor's standard knot is connected with the pre-embedded steel slab in pedestal 3, and the steel pipe column 1 in the superiors' standard knot is pushed up
End is provided with the top board for holding up steel box-girder.The quantity of steel pipe column is typically more than 3, preferably 4 in single standard knot.This
Sample one, the repeatable utilization of steel box-girder supporting construction is realized by dismountable multiple steel pipe rod structure, saves cost,
Take up an area small.
Adjustable bracket 7 is additionally provided between the top board and the superiors' standard knot, the adjustable bracket 7 includes that correspondence is marked
The Collapsible structure being made up of inner and outer tubes of the quantity of steel pipe column 1 in quasi- section, inner tube is inserted in outer tube；Outside adjustable bracket 7
Pipe is connected with the upper end of corresponding steel pipe column 1 in the superiors standard knots, and inner tube is connected with top board, and hydraulic jack is supported on top board
Lower surface adjusts entrance depth of the inner tube in outer tube with by top board, so as to adjust the height of adjustable bracket 7.So,
Support system highly can flexibly be adjusted, to ensure the effective support to steel box-girder.
The length of steel pipe column 1 in different layers standard knot is not quite similar.For example, same support frame can include steel pipe column length
Some standard knots of 3.2m and some standard knots of steel pipe column length 1.1m are spent, 3.2a+1.1b can be so constituted（A and b are
Natural number）Height, as needed adjust a, b size（Correspond to the quantity of standard knot）And coordinate adjustable bracket, you can
Easily reach the height of needs.So, when in use can be according to job site actual conditions by the suitable number of selection
The standard knot of amount and length and then can be reached with approaching object height by hydraulic jack jacking simultaneously top adjustable bracket
To object height, it is finely adjusted finally by setting pad or cushion block on top support frame, it is achieved thereby that high to support system
The arbitrariness regulation of degree.
The fixed mount 2 includes some cross bars and connects the brace of diagonal positions between adjacent two cross bar.Steel pipe column with
Cross bar and brace composition triangular structure, can so ensure the resistance to overturning of support system.
The cross bar is rectangular steel tube with brace.Compared with pipe, the bending strength and tensile strength of rectangular steel tube are bigger,
Quality is lighter, so while fixed mount stability is ensured can also loss of weight to a certain extent, it is convenient to install.
Steel pipe column 1 in the orlop standard knot is connected by rearmounted chemical anchor bolts 4 with the pre-embedded steel slab in pedestal 3.
So can be effectively firm on pedestal by support frame.
The pedestal 3 is poured using armored concrete and formed, and its strength grade of concrete is not less than C25.For steel box-girder
The strength and stability of pedestal is extremely important for support system, is not less than the concrete of C25 using strength grade to pour base
Seat is in order to the support to steel box-girder is better achieved.
The upper and lower ends of the steel pipe column 1 are equipped with horizontal connecting plate 6, and connecting plate 6 is provided with for bolted connection
Hole, is fixed by bolt between the steel pipe column 1 of adjacent modular section correspondence position by connecting connecting plate 6.Connecting plate can be in
Circle, connecting hole spaced set on plate, the quantity of connecting hole is preferably 12.The Fast Installation of steel pipe column can so be realized
And remove.
Reinforcement 5 is provided with the connecting plate 6.Can so make the connection between upper and lower steel pipe column more stable and firm.
The two ends of the fixed mount 2 are connected with reinforcement 5.When the fixed mount is made up of cross bar and brace, can pass through
The two ends of cross bar or brace are connected with reinforcement.So the resistance to overturning and safety of support system can be better ensured that
Property.
According to engineering site actual conditions, with reference to key elements such as steel box girder form, weight, construction live loads, from mark
Quasi- section plus adjustable bracket support system.When support system is installed, it is accurately positioned by measurement, fixed support is vertically and horizontally set at it
Ensure support system resistance to overturning, in work progress, implement in strict accordance with arrangement and method for construction and code requirement.It is equal using stress
The support system of the distinguishing features such as even, recycling, makes the construction of engineering more economically reasonable, and the city steel box-girder to being similar to is high
Summarized Account of Bridge Erection Construction has reference.
Finally illustrate, above example is only used to illustrate the technical solution of the utility model and unrestricted, although logical
Cross the utility model is described with reference to preferred embodiment of the present utility model, but one of ordinary skill in the art
It should be appreciated that various changes can be made to it in the form and details, without departing from appended claims institute
The spirit and scope of the present utility model for limiting.
