[0002] After precast construction, railway prestressed concrete box girders are generally stored on concrete platforms. Currently, one type of platform can only be matched with one type of railway prestressed concrete box girder. Although this method is feasible, it has the following problems: 1. The beam length and beam type of various railway prestressed concrete box girders have poor versatility. If there are multiple beam lengths and beam types, a wide variety of platforms are required, resulting in low utilization and poor economy, which is not conducive to the construction of large-scale precast railway prestressed concrete box girder bodies; 2. After the erection of a railway prestressed concrete box girder of one beam type, the corresponding platform will be idle and needs to be demolished and remade to accommodate the storage of railway prestressed concrete box girders of other beam types. Moreover, the construction time of the platform is long, which cannot meet the needs of rapid construction. Summary of the Invention

[0003] The purpose of this utility model is to provide a beam storage platform that can adapt to various beam types of railway prestressed concrete box girders. By setting foundation plates with different longitudinal spacing and fixed pads with different transverse spacing on the foundation plates, it is possible to store railway prestressed concrete box girders of different beam types and lengths, thereby improving the versatility of the platform, saving construction costs, and reducing temporary land use costs.

[0004] The purpose of this utility model is achieved as follows.

Both end foundation plates and the middle foundation plate are set on a compacted foundation, with the middle foundation plate positioned between the two end foundation plates. An end foundation is provided on top of each end foundation plate, and a middle foundation is provided on top of the middle foundation plate. A first fixed pad, a second fixed pad, and a third fixed pad are spaced apart on both end foundation plates and the middle foundation. The spacing between the second fixed pad, the third fixed pad, and the first fixed pad is arranged according to the beam type of the prestressed concrete box girder for railways.

[0006] Furthermore, the two end foundation plates and one middle foundation plate are set on the same straight line, the length of the middle foundation plate is equal to the length of the end foundation plates, and the width of the middle foundation plate is less than the width of the end foundation plates.

[0007] Furthermore, the two end foundations and one central foundation are located on the same straight line, the length of the central foundation is equal to the length of the end foundations, and the width of the central foundation is less than the width of the end foundations.

[0008] Furthermore, the top surfaces of the first fixed pad, the second fixed pad, and the third fixed pad are all at the same elevation, and the first fixed pad, the second fixed pad, and the third fixed pad at the same position on the two end foundations and the middle foundation are all on the same straight line.

[0009] Furthermore, the first fixed pad, the second fixed pad, and the third fixed pad are not arranged at equal intervals; the distance between the first fixed pad and the second fixed pad is greater than the distance between the second fixed pad and the third fixed pad.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model adapts to railway prestressed concrete box girders of different lengths by setting two end foundation plates with different longitudinal spacing and a middle foundation plate; and sets fixed pads with different transverse spacing on the three foundation plates, that is, by combining three types of fixed pads, it adapts to railway prestressed concrete box girders of different beam types, thereby achieving the purpose of storing railway prestressed concrete box girders of different beam types, improving the overall utilization rate of temporary land, reducing the cost of temporary land, and lowering construction costs.

[0012] 2. The use of rammed earth foundations and concrete base slabs at the bottom of both end foundations and one central foundation shortened the construction period, reduced project construction costs, and improved economic efficiency.

[0013] 3. It can replace the traditional concrete beam storage platform, improving the platform's versatility and increasing beam storage efficiency. Attached Figure Description
