The basic structure of construction elevator of the utility model bilayer raft plate, further, configuration is double-deck in the top layer raft plate Two-way concrete slab, is formed using C30 concretings.
The basic structure of construction elevator of the utility model bilayer raft plate, further, the thickness of the top layer raft plate is 350-450mm, the absolute altitude 100-200mm of the top mark higher than construction elevator road surface of top layer raft plate.
The basic structure of construction elevator of the utility model bilayer raft plate has the advantages that compared with prior art:
The basis that the basic structure of construction elevator of the utility model bilayer raft plate is combined using double-deck raft plate with support column Support, is set directly in the foundation ditch of ground, and construction elevator essential bearing stratum is reduced into balcony essential bearing stratum by backfill, The directly fixed stability in bottom is ensured;The construction of bottom raft plate and carriage post was first carried out before backfill, is returned The construction of top layer Base isolation system, the back filled foundation of support column surrounding backfill, by being compacted layer by layer, to support are carried out after the completion of filling out again Post also plays firm effect;Support column shores top layer raft plate, eliminates the elevator basis of backfill differential settlement generation The adverse effects such as deformation, sedimentation, effectively increase the security on construction elevator basis.
The basic structure of construction elevator to double-deck raft plate of the present utility model is described further below in conjunction with the accompanying drawings.
