Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail detailed description of the invention of the present utility model below in conjunction with accompanying drawing.It should be noted that, the utility model accompanying drawing all adopts the form of simplification and all uses non-ratio accurately, only in order to object that is convenient, aid illustration the utility model embodiment lucidly.
Shown in Fig. 1 ~ 4, lifter foundation mechanism of the present utility model, includes lifter foundation raft plate l0, is embedded with the pre-buried pedestal 101 of hoist in this lifter foundation raft plate 10.
Particularly, described lifter foundation raft plate 10 comprise reinforced concrete floor 102 and be positioned at described reinforced concrete floor 102 both sides and with the reinforcement foundation concrete beam 103 of described reinforced concrete floor 102 integral molding, the pre-buried pedestal 101 of described hoist is embedded in reinforcement foundation concrete beam 103;
The side that lifter foundation raft plate 10 is provided with reinforcement foundation concrete beam 103 is taken and is placed on outer wall of basement 20, and be provided with outer wall of basement bar planting 30 between lifter foundation raft plate 10 and outer wall of basement 20, the top of this outer wall of basement bar planting 30 anchors in lifter foundation raft plate 10, and the bottom of this outer wall of basement bar planting 30 is implanted in outer wall of basement 20;
The opposite side that lifter foundation raft plate 10 is provided with reinforcement foundation concrete beam 103 is taken by reinforced concrete wall 40 and is placed on the supporting dowel crown beam 50 at excavation slope place, hat beam bar planting 60 is provided with in described reinforced concrete wall 40, and the top being preced with beam bar planting 60 anchors in lifter foundation raft plate 10, the bottom of hat beam bar planting 60 is implanted in supporting dowel crown beam 50; The topping of described supporting dowel crown beam 50 upper surface will be rejected, pouring reinforcement concrete wall 40 again after hat beam bar planting 60 requires to reach.
Backfill 70 is filled with in basic deep foundation ditch between supporting dowel crown beam 50 and outer wall of basement 20, backfill 70 is covered with the bed course 80 be made up of plain concrete or steel concrete, and bed course 80 leans on the side of supporting dowel crown beam 50 to be also clipped between lifter foundation raft plate l0 and supporting dowel crown beam 50;
Described backfill 70 is tamped, and the coefficient of consolidation of backfill 70 is not less than 0.94, and backfill 70 does not participate in stressed, only plays bed course basis and template.
Described reinforcement foundation concrete beam 103 comprises two longerons, taking for one in described two longerons is placed on outer wall of basement 20, another root in two longerons is taken by reinforced concrete wall 40 and is placed on the supporting dowel crown beam 50 at excavation slope place, described outer wall of basement bar planting 30 anchors in the longeron above outer wall of basement 20, and described hat beam bar planting 60 anchors in the longeron above supporting dowel crown beam 50.
Beam level in longeron is indulged muscle and is directly arrived the disconnection of outer wall of basement 20 limit, and the waist muscle in longeron is 6 diameters is the reinforcing bar of 14mm.Reinforcement in longeron is not connected with outer wall of basement 20, to limit, shear wall hole disconnection on the ground, only often hold 6 diameters to be that the reinforcing bar of 14mm is connected with outer wall of basement 20, the termination outer wall of basement 20 of two longerons need not pick cutter, can reduce the impact on building like this.
