Abstract
A bailey beam with a staggered arrangement structure is assembled of a bailey frame and a sending window. The bailey frame comprises a plurality of unit truss slices, a plurality of page slices and a plurality of rotating shafts. The edge of one end of each page slice is provided with at least two rotating shaft arrangement pipes which are arranged at intervals, and the circle centers of the two rotating shaft arrangement pipes are in the same line. A bolt through hole is arranged in the center portion of the page slice. Two to four page slices are connected through a method of utilizing the rotating shafts to penetrate through the rotating shaft arrangement pipes. The page slice is connected with one end of each unit truss slice, and therefore an elastic mesh-shaped bailey frame structure is composed. The bailey beam has the advantages that the unit truss slice forms the elastic mesh-shaped bailey frame structure through a method of connecting the page slice and the rotating shaft in a rotary mode, due to the fact that the unit truss slices are horizontally connected, horizontal strength and horizontal stability of the whole bailey frame is increased on the premise of not reducing vertical strength of the whole bailey beam, not prolonging a construction period and not increasing budget cost, therefore, a problem of heeling does not appear.
Description
Technical field
The invention belongs to technical field of bridge engineering, particularly relate to a kind of Bailey beam with staggered structure.
Background technology
Bailey beam is the trusses being assembled by being positioned at a window at two ends by Bailey bracket, and wherein Bailey bracket is comprised of the many groups of Bailey truss that be arranged in parallel, and every group of Bailey truss is connected successively and formed by a plurality of unit truss sheet.Because Bailey beam has, set up rapidly, the advantage such as mobility strong, be therefore usually used in engineering construction, such as for erection construction platform and engineering sidewalk bridge etc.But, there is following point in conventional Bailey beam at present: although above-mentioned Bailey beam has very large flexural strength, but, as mentioned above, because many group Bailey truss sheets be arranged in parallel, laterally do not connect each other, so lateral stiffness is poor, so very possible generation rolls problem with regard to monolithic Bailey truss sheet, thereby affect the integral working of Bailey beam.In addition, while installing due to above-mentioned many group Bailey truss sheets, need to arrange separately, so operating process more complicated, so the construction period is long.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of Bailey beam with staggered structure that can greatly improve lateral stiffness and can shorten the construction period.
In order to achieve the above object, the Bailey beam with staggered structure provided by the invention is assembled by Bailey bracket and the window of sending out that is connected to Bailey bracket two ends; Described Bailey bracket comprises multi-disc unit truss sheet, multi-disc hinge and Duo Gen axis of rotation; Wherein an end margin of every hinge is provided with the axis of rotation that at least two standoff distance settings and the center of circle be positioned at same straight line pipe is set, and centre has been formed through a bolt hole; Two to four hinges arrange pipe with axis of rotation on it and are mutually arranged alternately Cheng Yilie and utilize an axis of rotation to run through the mode that all axis of rotation arrange pipe and link together; Every hinge utilizes the mode of bolt-through bolt hole and one end of a blade unit truss sheet to link together, and forms thus telescopic grid type Bailey bracket structure.
Described unit truss sheet equal in length or unequal.
Described is connected with device for fixing end part in selectable mode between the adjacent two blade unit truss sheet outer ends of Bailey bracket outer end.
The Bailey beam with staggered structure provided by the invention has the following advantages:
1) truss sheet in unit is rotatably connected with axis of rotation by hinge and forms telescopic grid type Bailey bracket structure, because unit truss sheet also has connection between laterally, so can be not reducing the whole longitudinal strength of Bailey beam, do not increase the transverse strength and the lateral stability that under the prerequisite of construction period and estimated cost, increase whole Bailey bracket, therefore there will not be inclination problem.
2) because unit truss sheet, hinge and axis of rotation are standard component, therefore purchase or lease are all more convenient, and are convenient to assembling and constructing operation, and the construction period is short.
3) this structure, high trestle large in bridge span, bridge location basis more complicated, intermediate demand leave passage or are not suitable for having more advantage under the condition of full framing.
Accompanying drawing explanation
Fig. 1 is Bailey bracket structure top view in the Bailey beam with staggered structure provided by the invention.
Fig. 2 is the hinge between unit truss sheet and revolute axes configuration lateral view in above-mentioned Bailey beam.
Fig. 3 is the hinge between unit truss sheet and revolute axes configuration top view in above-mentioned Bailey beam.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the Bailey beam with staggered structure provided by the invention is elaborated.
As shown in Fig. 1-Fig. 3, the Bailey beam with staggered structure provided by the invention is assembled by Bailey bracket and the window of sending out that is connected to Bailey bracket two ends; Described Bailey bracket comprises multi-disc unit truss sheet 1, multi-disc hinge 2 and Duo Gen axis of rotation 3; Wherein an end margin of every hinge 2 is provided with the axis of rotation that at least two standoff distance settings and the center of circle be positioned at same straight line pipe 4 is set, and centre has been formed through a bolt hole 5; Two to four hinges 2 arrange pipe 4 with axis of rotation on it and are mutually arranged alternately Cheng Yilie and utilize an axis of rotation 3 to run through the mode that all axis of rotation arrange pipe 4 and link together; Every hinge 2 utilizes the mode of bolt-through bolt hole 5 and one end of a blade unit truss sheet 1 to link together, and forms thus telescopic grid type Bailey bracket structure.
Described unit truss sheet 1 equal in length or unequal, can utilize hinge 2 and axis of rotation 3 to connect into the multiple Bailey bracket with different length, to meet the needs of different engineerings like this.
Described is connected with device for fixing end part 6 in selectable mode between adjacent two blade unit truss sheet 1 outer ends of Bailey bracket outer end.
Now the using method with the Bailey beam of staggered structure provided by the invention is described below: when needs are used this Bailey beam, first by staff's ground Shang Jiang unit truss sheet 1 at the construction field (site), hinge 2 and axis of rotation 3 connect into the scalable grid type Bailey bracket that can meet Len req and span according to requirements, if needed, can between adjacent two blade unit truss sheet 1 outer ends in Bailey bracket outer end, install a fastening devices 6, then above-mentioned Bailey bracket is lifted into installation site with folding mode, make it be latticed Bailey bracket horizontal spreading afterwards, according to the method for prior art, at the two ends of Bailey bracket, connect respectively afterwards one and send out window, can be made into thus the described Bailey beam with staggered structure.
