Pass-Through Head Assembly for a Grid Shoring System

A platform support comprising:

• a first pass-through head assembly comprising:
• a first central shaft extending between a first top end plate and a first bottom end plate, each of the first top end plate and the first bottom end plate defining an aperture that aligns with an interior cavity of the first central shaft,
• a first plurality of support bars extending from an exterior surface of the first central shaft and a surface of the first bottom end plate, each support bar of the first plurality of support bars extending along a portion of an axial length of the first central shaft,
• a first seat circumferentially disposed about the first central shaft and configured to support at least a first beam, the first seat defining an aperture sized to allow the first seat to pass over the first central shaft and the first plurality of support bars, and
• a first seat support plate circumferentially disposed about the first central shaft between the first seat and the first bottom end plate, and defining an aperture sized to allow the first seat support plate to pass over the first central shaft and the first plurality of support bars, the first seat support plate configured to rest on the first plurality support bars in a first position and pass over the first plurality of support bars in a second position;
• an adjustable shaft assembly supported by the first top end plate and extending into the interior cavity of the first central shaft;
• and
• a prop coupled to the first bottom end plate axially opposite the first central shaft.

A grid shoring system comprising:

• a plurality of platform supports arranged in an array, each platform support comprising:
• a first pass-through head assembly comprising:
• a first central shaft extending between a first top end plate and a first bottom end plate, each of the first top end plate and the first bottom end plate defining an aperture that aligns with an interior cavity of the first central shaft,
• a first plurality of support bars extending from an exterior surface of the first central shaft and a surface of the first bottom end plate, each support bar extending along a portion of an axial length of the first central shaft,
• a first seat circumferentially disposed about the first central shaft, the first seat defining an aperture sized to allow the first seat to pass over the first central shaft and the first plurality of support bars, and
• a first seat support plate circumferentially disposed about the first central shaft between the first seat and the first bottom end plate, and defining an aperture sized to allow the first seat support plate to pass over the first central shaft and the first plurality of support bars, the first seat support plate configured to rest on the first plurality of support bars in a first position and pass over the first plurality of support bars in a second position,
• an adjustable shaft assembly supported by the first top end plate and extending into the interior cavity of the first central shaft, and
• a prop coupled to the first bottom end plate opposite the first central shaft;
• a first plurality of main beams, each main beam coupled to the first seat of two adjacent platform supports of the plurality of platform supports and parallel to at least one other main beam;
• a first plurality of secondary beams, each secondary beam coupled to the first seats of two adjacent platform supports of the plurality of platform supports, or two main beams of the first plurality of main beams;
• and
• at least one panel disposed on top of at least two secondary beams of the first plurality of secondary beams.
