Fig. 1, 12-18 are combined, wherein fig. 13 (b) to 18 (b) are left side views of fig. 13 (a) to 18 (a), respectively; the embodiment of the invention provides an erection construction method of a cover plate structure of an assembly type building, which comprises the following steps:
step S100, after the girder transporting vehicle transports the longitudinal girder pieces 61 to the edge of the foundation pit 7 of the girder yard, the gantry crane moves to the edge of the foundation pit 7 and lifts the longitudinal girder pieces 61;
step S200, the longitudinal beam pieces 61 are transported to the erection position in the foundation pit 7 by the portal crane, and the longitudinal beam pieces 61 are erected on the pedestal 8 arranged at the erection position;
step S300, after the beam transporting vehicle transports the beam piece 62 to the edge of the foundation pit 7, the gantry crane moves to the edge of the foundation pit 7 and lifts the beam piece 62;
step S400, the gantry crane transports the beam pieces 62 to the erection position in the foundation pit 7, and the beam pieces 62 are erected on the pedestal 8 or the side beam pieces 61 provided at the erection position.
The foundation pit 7 of the fabricated building in the beam yard has a certain depth, and is internally provided with a pedestal 8 for storing beams, namely beam sheets 6 for erecting a cover plate structure of the fabricated building; the lower end of the pedestal 8 is supported on a supporting surface (ground), and the upper end of the pedestal 8 (i.e. the end of the pedestal in the positive direction of the Z axis in fig. 12) is in a step-shaped structure, so that the beam piece 6 is erected on the pedestal 8; the beam piece 6 of the cover plate structure comprises a longitudinal beam piece 61 and a transverse beam piece 62. Moreover, the pedestals 8 in the foundation pit 7 are arranged at intervals in the transverse direction (i.e. the Y-axis direction in fig. 12) and the longitudinal direction (i.e. the X-axis direction in fig. 12) of the beam field, so that on one hand, the pedestals 8 are prevented from interfering with the movement of the portal crane, and the portal crane is ensured to move smoothly in the foundation pit 7; on the other hand, the two ends of the beam piece 6 can be respectively erected on the two adjacent pedestals 8 to improve the stability of the beam piece 6. For the steps S100 and S300, before the beam piece 6 is erected, the beam piece 6 needs to be transported to the edge position of the foundation pit 7 in advance, so that the portal crane in the foundation pit 7 can take the beam; for steps S200 and S400, after the gantry crane takes the beam, the gantry crane transports the beam piece 6 to a corresponding erection position within the foundation pit 7, and erects the beam piece 6 on the pedestal 8 located at the erection position. In the embodiment, the longitudinal beam pieces 61 are erected firstly, then the transverse beam pieces 62 are erected, and the transverse beam pieces 62 are erected on the pedestal 8 or the longitudinal beam pieces 61, so that on one hand, the longitudinal movement of the portal crane in a beam yard is facilitated (namely, the portal crane moves longitudinally along the beam yard), and the orderly erection work of the beam pieces 6 is ensured; on the other hand, after the longitudinal beam pieces 61 are erected, the cross beam pieces 62 can be erected on two adjacent longitudinal beam pieces 61 which are positioned in different rows, so that the situation that the longitudinal beam pieces 61 and the cross beam pieces 62 occupy too much space of the foundation pit 7 when arranged in parallel is avoided, and the capacity of the beam pieces 6 of the beam field in the foundation pit 7 is improved, namely the number of stored beams of the foundation pit 7 is improved; therefore, the erection construction process of the cover plate structure of the assembly type building is simplified and the erection construction efficiency of the cover plate structure of the assembly type building is improved by implementing the erection construction method of the cover plate structure of the assembly type building.
Further, the erection of the cross beam pieces 62 in step S400 should be from far to near (i.e. from the position of the girder transporting vehicle far from the edge of the foundation pit 7), so as to avoid the erected cross beam pieces 62 from obstructing the longitudinal movement of the gantry crane.
Further, a plurality of beam pieces 62 are preferably erected on the pedestal 8 and the erected beam pieces 61 to increase the capacity of the beam pieces 6 in the foundation pit 7.
Optionally, as shown in fig. 1, fig. 2, and fig. 12 to fig. 14, the step S200 specifically includes the following steps:
step S210, the longitudinal beam pieces 61 are transported to the erection position in the foundation pit 7 by the portal crane, and the longitudinal beam pieces 61 are erected on two adjacent pedestals 8 which are arranged at the erection position and are arranged along the longitudinal direction of the beam yard;
step S220, the gantry crane erects the longitudinal beam pieces 61 on the pedestals 8 on the row and two ends where the gantry crane is located.
Be equipped with multiseriate pedestal 8 in the foundation ditch 7 in beam field, and a plurality of pedestals 8 of every pedestal 8 set up along the longitudinal interval in beam field, correspondingly, are located the same interval setting of pedestal 8 in different rows. For step S210, when erecting the longitudinal beam pieces 61, the longitudinal beam pieces 61 are erected on two adjacent pedestals in each column of pedestals 8 in the longitudinal direction of the beam field, so that the longitudinal beam pieces 61 do not interfere with the longitudinal movement of the gantry crane in the foundation pit 7, and the transverse beam pieces 62 are conveniently erected on the longitudinal beam pieces 61 in the transverse direction (i.e., the direction perpendicular to the longitudinal beam pieces 61) in the subsequent step. Thus, according to step S220, the gantry crane erects the longitudinal beam pieces 61 in place on the pedestals 8 located at the spanned row and the two ends (i.e., the columns through which the two cantilevers 212 of the gantry crane pass in the beam field foundation pit 7), i.e., the longitudinal beam pieces 61 at the spanned row and the two ends of the gantry crane are erected; the gantry crane is arranged to be a column of a pedestal 8 on which a support leg mechanism 3 (described later) of the gantry crane is arranged to cross in the foundation pit 7, and the pedestals 8 at both ends of the gantry crane are the pedestals 8 on which two cantilevers 212 (described later) at both ends of the gantry crane pass in the foundation pit 7.
Optionally, as shown in fig. 1, fig. 2, and fig. 12 to fig. 14, the step S400 specifically includes the following steps:
step S410, the portal crane transports the beam pieces 62 to an erection position in the foundation pit 7, and the beam pieces 62 are erected on two adjacent pedestals 8 which are arranged at the erection position and arranged transversely along the beam field, or the beam pieces 62 are erected on two adjacent columns of beam pieces 61 arranged at the erection position;
step S420, the gantry crane erects the beam piece 62 on the pedestals 8 on the row and both ends where the gantry crane is located.
After the step S220 is completed, the process proceeds to step S300, and the gantry crane returns to the edge of the foundation pit 7 to hoist the beam piece 62; then, the process proceeds to step S410, where the beam pieces 62 are erected on two adjacent pedestals 8 located at the erection positions and arranged in the beam field in the transverse direction, or two adjacent columns of the beam pieces 61 located at the erection positions. In this way, in step S400, the gantry crane sequentially spans the columns and the upper beam pieces 62 on the pedestals 8 at both ends in the order of the distance from the top to the bottom, and the foundation pit 7 is erected with the upper beam pieces 6.
Furthermore, when a plurality of erection positions (pedestals 8) are arranged in the train, the gantry crane needs to be changed to another position for erection after the erection of the cross-row beam pieces 6 and the beam pieces 6 at the two ends are finished, so that the longitudinal beam and the cross beam 22 at the edge of the foundation pit 7 where the beam transporting vehicle is located can be left for final erection, and the gantry crane can conveniently move transversely (namely the gantry crane moves transversely along the beam field) from the edge of the foundation pit 7 where the beam transporting vehicle is located to leave the original position; moreover, in the process that the gantry crane leaves the original position, the gantry crane can move row by row, and the gantry crane can conveniently complete erection of the longitudinal beam and the cross beam 22 at the original position through the trolley mechanism at the cantilever 212.

step S260, the longitudinal beam pieces 61 are transported to the erection positions of two columns of pedestals 8 adjacent to the barrier in the foundation pit 7 by the portal crane, and the longitudinal beam pieces 61 are erected on the two adjacent pedestals 8 which are arranged at the erection positions and are arranged along the longitudinal direction of the beam field;
step S270, the gantry crane erects the girder pieces 61 in place on the two rows of pedestals 8 adjacent to the obstacle.
Further, step S400 specifically includes the steps of:
step S460, the portal crane transports the beam piece 62 to cross the obstacle, moves to the erection position of two rows of pedestals 8 adjacent to the obstacle in the foundation pit 7, and erects the beam piece 62 on the pedestals 8 or the longitudinal beam piece 61 arranged at the erection position;
step S470 is to erect the beam pieces 62 on the two rows of pedestals 8 adjacent to the obstacle by the gantry crane.
When an obstacle (such as a tower crane) is arranged in the beam yard, the obstacle can block the longitudinal movement of the gantry crane at the obstacle, so that the erection of the beam pieces 62 at the two rows of pedestals 8 adjacent to the obstacle is interfered; therefore, when the portal crane erects the beam pieces at the two rows of pedestals 8 beside the obstacle, the erection of the longitudinal beam pieces 61 on the two rows of pedestals 8 adjacent to the obstacle is completed according to the step S260 and the step S270; then, according to step S460 and step S470, the gantry crane passes over the obstacle by its own movement, and the erection of the beam piece 6 is completed.
