Detailed Description
The invention will be further explained with reference to the following drawings and embodiments:
a Bailey beam supporting system used for construction of a subway station comprises two longitudinal Bailey beam groups 2 erected on a negative two-layer plate longitudinal beam of the subway station, a plurality of transverse Bailey beam groups 4 erected on the longitudinal Bailey beam groups 2 and I-steel 3 erected on the transverse Bailey beam groups 4; the 4 groups of the transverse Bailey beam groups are connected into a whole through a cross frame, so that balanced stress is realized. The scaffold base with the middle plate at the negative layer is directly erected on the I-steel 3 to construct the main structure of the subway station.
Preferably, each longitudinal beret group 2 is composed of 4 rows of single-layer beret beams, and each transverse beret group 4 is composed of 3 rows of single-layer beret beams. The interval between the transverse Bailey beam group 4 is 0.9 m; wherein, the inter-block spacing of the transverse Bailey beam group 4 adjacent to the upright post for supporting the negative layer of the subway station is 3.2 m. The distance between the I-shaped steel 3 is 1.5 m.
In addition, the transverse Bailey beam group 4 is arranged in a steel bridge truss mode, and the transverse length is arranged according to the scaffold body.
The construction steps are illustrated below by means of specific engineering examples:
firstly, assembling Bailey sheets 1 on the ground and connecting and assembling Bailey beams through a support frame 5, wherein 4 rows of single-layer Bailey beams form a longitudinal Bailey beam group 2, and 3 rows of single-layer Bailey beams form a transverse Bailey beam group 4; and then, using a truck crane to hoist the two groups of longitudinal Bailey beam groups 2 on the longitudinal beams of the negative two-layer plate of the subway station.
Secondly, hoisting the connected transverse Bailey beam groups 4 in place by using a truck crane according to the sequence of the middle and the two sides, erecting the transverse Bailey beam groups 2 on the longitudinal Bailey beam groups, wherein the interval of each transverse Bailey beam group 4 is 0.9m, the interval of the transverse Bailey beam group 4 adjacent to the upright post for supporting the negative layer of the subway station is 3.2m, and the groups are connected into a whole by using a cross frame to realize balanced stress;
and thirdly, erecting I-beams 3 on the transverse Bailey beam group 2 at intervals of 1.5m along the longitudinal direction to complete the erection of the whole Bailey beam supporting system. A middle plate scaffold base of the negative layer can be directly erected on the I-shaped steel 3, the construction of a main structure of the subway station is achieved, the arrangement of the negative three-layer scaffold of the subway station is saved, and therefore the engineering cost is saved. Meanwhile, the shield machine can be driven into the shaft during the construction period of the main structure of the subway station, the synchronous construction of the assembly debugging of the shield machine and the main structure of the station is realized, and the construction period is saved.
Because the shield construction is carried out in step below the Bailey beam supporting system, in order to eliminate potential safety hazards and guarantee the personal safety of constructors below, a safety net is arranged below the Bailey beam supporting system in the middle of the negative two-layer plate for protection, and the constructors below the safety net are prevented from being injured by falling objects.
After the subway station construction was accomplished, demolish the scaffold frame, and the utility model discloses a bei lei liang supports the system and can regard as station major structure to remain, supports a burden plywood.
