In second groove 25 of one cylinder 2, then in the side welding first backwards to vertical muscle 6 of the first built-in fitting 15 and the second built-in fitting 22
Steel plate 4 welds the second steel plate 5 in the side backwards to vertical muscle 6 of third built-in fitting 23 and the 4th built-in fitting 32, so not only makes
Pedestal 1, the first cylinder 2 and 3 three of the second cylinder securely connect, but also are further ensured that on the first cylinder and the second cylinder and hold
The shearing force in the horizontal direction received can effectively pass to pedestal, finally the gap also between adjacent two components up and down
Middle filling grouting material, so as to uniformly transferring for isolated footing vertical load.For traditional free band cylinder integral cast-in-situ basis
For, either rim of a cup formula, anchor bolt type or direct-burried reinforcing bar formula are both needed to live formwork, tie up reinforcing bar, placing concrete is needed to coagulation
Soil is conserved, and needs to carry out the construction of superstructure after concrete reaches design strength.And the assembly in the application
Formula isolated footing can save live formwork, concreting and curing time, and subsequent apply can be quickly carried out after the completion of assembled
Work, saves the duration, and work progress is environmentally protective.The utility model overcomes the shortcomings that Foundation Fieldbus field placing concrete construction, symbol
It closes China and pushes the needs of assembled architecture energetically, be of great immediate significance and engineering application value.
