Detailed Description
Description of the patent principles
The operation of a lightweight straddle-type monorail transit structure is further described with reference to the accompanying drawings, and it should be noted that the embodiments described in the drawings are merely exemplary in nature and should not be construed as limiting the invention.
The operation principle of the light straddle type monorail transit structure based on the patent is firstly demonstrated with reference to fig. 1-3. From the stress perspective, the assembled straddle type steel box track beam 3a is mounted on the tops of the cover beam 6a and the cover beam 7a through the steel support 8a and the steel support 10a, the assembled straddle type steel box track beam 4a is mounted on the tops of the cover beam 6a and the cover beam 7a through the steel support 9a and the steel support 11a, and the assembled straddle type steel box track beamGravity G of straddle type steel box track beam1With the train gravity G to which it is subjected2With impact force F1The steel support is transmitted to the cover beam, and it should be noted that the specific connection mode and the connection arrangement mode of the steel support can be adjusted according to the beam field of the track beam. The fabricated straddle type steel box track beam 3a and the fabricated steel box track beam 4a are connected through a transverse connecting system 20a, and the transverse rigidity of the whole structure can be increased through the connecting system.
The construction period of the assembled steel pier is shown as the following formula:
in the formula: t is1-reinforcement cage binding time, about 3 d;
T2-erecting the formwork for a time of about 1 d;
T3-casting concrete for a time of about 1 d;
T4concrete curing time, about 28 days.
The total construction period of the existing single-rail concrete bridge pier is about 33d, and the total construction period of the fabricated steel bridge pier is 4 d. The assembled steel bridge pier can greatly shorten the construction period of the light straddle type monorail traffic structure bridge pier and improve the construction efficiency of the light straddle type monorail traffic structure.
With reference to fig. 8-10, the main characteristic of the monorail transportation structure is that the track beam is a stressed structure, and the beam height h of the track beam needs to be considered0High span ratio h to span l0The influence of/l, thereby requiring an increase in beam height h0The track beam is a vehicle running structure, and the requirement of vehicles is met to reduce the beam width b of the track beam2Determining the height h of the track beam after comprehensive consideration0Width of beam b2From the torsional section coefficient:
Wt＝αhb3
wherein α is related to the ratio h/b of the cross-sectional dimension, and the height h of the concrete box girder is known0In certain cases, the transverse dimension b of the concrete box girder2The higher the concrete box beam is, the larger the torsional section coefficient of the concrete box beam is, and the transverse connecting system enables the assembled steel box track beams on the left side and the right side to be converted from single stress to integral stress, so that the integral torsion resistance of the structure is effectively improved.
According to the simple-supported beam single-point stress deflection line equation:
and the formula of the moment of inertia of the rectangular section:
the transverse connection system converts the independent stress of the assembled steel box track beams on the left side and the right side into the integral stress, and can greatly reduce the vertical deflection of each point of the existing straddle type track beam. The aim of high speed of the light straddle type monorail traffic structure is fulfilled.
This patent is further illustrated with reference to examples.
