Description
Technical field
The utility model relates to a kind of straddle-type monorail Simple-supported PC Rail Beam in Light Rail to install support construction, belong to track girder construction skill
Art field.
Background technique
Straddle type monorail beam type in rolling stock section uses Simple-supported PC Rail Beam in Light Rail structure, deck-molding 180cm, deck-siding 69cm, section
For rectangular section.Because track girder installation back rest bottom is apart from ground level 62cm, height difference is smaller, is currently using economic convenient pillow
The mode that grillage divides into simple sandbox is set a roof beam in place, and tie dimensions are length × width × height=80cm × 20cm × 20cm.Due to purchasing pillow
The wooden compactness is inconsistent, and the lumps of wood need to be laid with 3 layers, deforms larger (having 3~5cm sedimentation) after falling beam, needs cushioning steel plate repeatedly,
It falls that the beam time is long, reduces the efficiency set a roof beam in place.In addition it is observed after beam body installation in different periods, discovery still has sedimentation and inclines
Oblique situation, beam body is longer stable period, need to repeatedly adjust beam and observe repeatedly, waste a large amount of manpowers, be otherwise unable to reach design ±
The high-precision requirement of 3mm.
Utility model content
In view of the above drawbacks of the prior art, the utility model provides a kind of straddle-type monorail Simple-supported PC Rail Beam in Light Rail installation
Support construction is required with meeting track girder design and construction, while being accelerated construction efficiency, being reduced and adjust beam and measurement workload.
Technical solutions of the utility model are as follows:
A kind of straddle-type monorail Simple-supported PC Rail Beam in Light Rail installation support construction, including welding the rectangle surrounded by four rectangular tubes
Frame, the rectangular frame are parallel to the horizontal plane, and are equipped with finish rolling spiral shell along the vertical direction respectively on four angles of the rectangular frame
The height of line steel, four fining twisted steels is identical, above and below the rectangular tube on each described fining twisted steel
Screw-thread steel nut is arranged at the position of two end faces respectively；
It further include the first backing plate, four fining twisted steels are mounted on first backing plate, on first backing plate also
It is provided with jack, which is located in the rectangular frame.
By adopting the above technical scheme, beam body is fallen on four rectangular tubes, jack is placed in rectangular frame and is carried out
Adjust beam.Beam body width is 69cm, therefore direction across bridge rectangle length of tube is set as 100cm, 70cm is set as to length along bridge, using 4
Root rectangular tube is as support platform.It adjusts beam Shi Xianyong jack to play back, then passes through the screw thread on rotation fining twisted steel
The height of steel nut adjustment rectangular frame need to guarantee that rectangular frame is in level when adjusting beam, after measurement absolute altitude meets design, adjustment
Screw-thread steel height of nut simultaneously tightens unloading jack, completes to adjust beam process, and use is more convenient, while avoiding beam body and support
Flexible contact deformation occurs between structure and causes to adjust beam repeatedly.
Preferably, the lower end of each fining twisted steel is provided with the second backing plate, which is fixed on
On first backing plate, and the surrounding on each described fining twisted steel at the position of its lower end is provided with reinforcement
Plate, the stiffening plate are welded to connect with the fining twisted steel and the second backing plate respectively.
Preferably, be also cased with position limiting structure on each described fining twisted steel, the position limiting structure be it is up big and down small,
The hollow columnar structures of upper short lower length, and the upper end of the position limiting structure and the screw-thread steel spiral shell below the rectangular tube
It is close to female lower end.
The utility model has the advantages that the straddle-type monorail Simple-supported PC Rail Beam in Light Rail of the utility model installs support construction, by adjusting screw thread
The height of steel nut tightens screw-thread steel nut and unloads jack to adjust the height of rectangular tube after measurement absolute altitude meets design,
It completes to adjust beam process, it is very easy to use, while avoiding and flexible contact deformation occurs between beam body and support construction and causes
Beam is adjusted repeatedly, is improved construction efficiency, is reduced and adjust beam and measurement workload.
Detailed description of the invention
Fig. 1 is the main view of the utility model；
Fig. 2 is the left view of Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
Straddle-type monorail Simple-supported PC Rail Beam in Light Rail as shown shown in Figure 1 and Figure 2 installs support construction, including by four rectangles
Pipe 1 welds the rectangular frame surrounded, which is parallel to the horizontal plane, on four angles of rectangular frame respectively along the vertical direction
It is equipped with fining twisted steel 2, the height of four fining twisted steels 2 is identical, close to rectangular tube 1 on each fining twisted steel 2
It is arranged with screw-thread steel nut 3 respectively at the position of upper and lower two end faces, rectangular tube 1 and screw-thread steel nut 3 glide in order to prevent, In
It is further sleeved with position limiting structure 9 on each fining twisted steel 2, which is the hollow columnar of up big and down small, upper short lower length
Structure, the i.e. upper diameter of position limiting structure 9 are greater than its underpart diameter, and the length on top is less than the length of its underpart, and limits knot
It is close to the lower end for the screw-thread steel nut 3 for being located at 1 lower section of rectangular tube the upper end of structure 9；
