The first short side beam 102 and the second short side beam 104 are both made from a single identical I-beam. A gusset plate 6 is welded to the flange connection of the first long side beam 101, the first short side beam 102, the second long side beam 103, and the second short side beam 104.

[0028] The main beam 105 is welded and installed at the lower center of the first long side beam 101 and the second long side beam 103. The main beam 105 is parallel to the first short side beam 102. The length of the main beam 105 is the same as the width of the secondary beam platform 1. The main beam 105 is formed by welding three I-beams with the same structure together.

[0029] The force transmission column 2 includes two channel steels 201 with identical structures. The grooves of the two channel steels 201 are welded together to form a "U" shape. Multiple force transmission column gusset plates 202 are evenly distributed at the weld seam of the two channel steels 201. A force transmission column base plate 203 is welded to the lower end of the force transmission column 2. A fixing mechanism is provided between the force transmission column 2 and the main beam 105 to allow the force transmission column 2 to be detachably connected to the main beam 105.

[0030] The fixing mechanism includes a first connecting plate 3, a second connecting plate 4, a plurality of second fixing nuts 302, and a plurality of second fixing bolts 402.

[0034] The working principle of a plate load testing platform for confined spaces: When not in use, the second fixing bolt 402 and the second fixing nut 302 are removed from the first connecting plate 3 and the second connecting plate 4, thereby separating the first connecting plate 3 and the second connecting plate 4, and thus separating the secondary beam platform 1 and the main beam 105 from the force transmission column 2. This facilitates separate transportation and daily storage management, meeting the needs of plate load testing in confined spaces, and can also be used as a conventional plate load testing device when the force transmission column 2 is not connected.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
