Further, be provided with bed course between levels box like structure, course is rubber, polyamine material, nylon or non-woven fabrics.
Further, each box like structure comprises circular arc inwall, circular arc outer wall, both sides sidewall and top board and base plate, and wherein, top board and base plate are provided projectingly on circular arc inner wall and form ledge.
Further, each box like structure both sides sidewall is provided with two row's hoop reserving holes, in hoop reserving hole, is provided with connecting elements, complete the assembled of adjacent two box like structure by connecting elements; The top board of each box like structure and base plate are provided with vertical reserving hole, in vertical reserving hole, are provided with connecting elements, complete the assembled of box like structure between adjacent layer by connecting elements; Each box like structure circular arc outer wall is provided with reserving hole, is provided with connecting elements in reserving hole, by connecting elements, each box like structure is connected with liner structure; Box like structure ledge and circular floor plate are provided with reserving hole, are provided with connecting elements in reserving hole, complete the assembled of circular floor plate and box like structure by connecting elements; Box like structure, circular floor plate, connecting elements and liner structure are jointly stressed.
Further, described connecting elements is bolt.
Further, described liner structure is reversal of the natural order of things pipe-plate lining structure.
Further, described box like structure is steel work.
The above-mentioned construction method without median septum box-like assembling underground stereo garage parking, comprises the steps:
The first step: excavation of foundation pit, completes reversal of the natural order of things pipe-plate lining structure;
Second step: same layer box like structure is put down foundation ditch inside in order;
3rd step: adopt connecting elements to be connected and fixed between the adjacent box like structure of same layer, each box like structure is connected by connecting elements with pipe-plate lining structure;
4th step: install circular floor plate in same layer, realizes the assembled of circular floor plate and box like structure by connecting elements;
5th step: repeat the 3rd step and the 4th step, be connected and fixed by connecting elements between adjacent layer box like structure;
6th step: the construction completing underground stereo garage parking accessory structure.
Compared with prior art, the present invention has following beneficial effect:
1. box like structure and circular floor plate are precast assembly, and each box like structure and circular floor plate, in factory process, are directly transported to job site.This box like structure sizing deviation is less, accuracy is high, and in construction works, operative is simple, quick, saves time, the reduction of erection time.
2. box like structure reasonable stress, this agent structure is jointly stressed by each box like structure, circular floor plate, connecting elements and liner structure, has given full play to the vertical mechanical property of liner structure.Reasonably make use of liner structure, save box like structure, circular floor plate and connecting elements material, cost-saving.

Detailed description of the invention
As shown in figs. 1-7, have median septum box-like assembling underground stereo garage parking embodiment for inventing one, this underground three-dimensional garage forms primarily of multiple steel work box like structure 3, circular floor plate 6, bed course 10.Underground three-dimensional garage central area is circular floor plate 6, and surrounding is box like structure 3.The arranged outside of box like structure 3 has liner structure 2.Wherein, each box like structure 3 is fan annular.Each box like structure 3 and circular floor plate 6 are provided with reserving hole 5.All be connected by the connecting elements 4 in reserving hole 5 between same layer box like structure 3, between levels box like structure 3, between box like structure 3 with circular floor plate 6 and between box like structure 3 with liner structure 2, connecting elements 4 adopts bolt.Realize the precast assembly of box like structure 3, circular floor plate 6 and liner structure 2, thus complete underground stereo garage parking agent structure.
The concrete sectional dimension of this embodiment is as follows: this underground garage agent structure outward flange diameter is 28m, and the degree of depth is 12m, totally 5 layers, and often high is layer by layer 2.4m.Each box like structure 3 can stop two, and every layer stops 14, and this garage has parking 70 altogether.Middle border circular areas is garage mechanical transport passage, and traffic aisle diameter is 16m.Rubber spacer 10 is provided with between levels box like structure 3.
The central angle that inside and outside each box like structure 3, circular arc is corresponding is 36 °, and outer diameter is 28m, and base plate annular diameters is 15.5m, and sidewall annular diameters is 16m.Every one deck adopts 7 box like structure 3 assembled.Each box like structure 3 floor height is 2.4m.Box like structure top board and base plate thickness are 35mm.Top board and base plate are provided projectingly on circular arc inner wall and form ledge.
Each box like structure 3 sidewall arranges two row's bolts, and reserved bolt box hole 5 is 40mm, reserves bolt box hole 5 respectively at 1/3 and 2/3 ring width place, is highly distance base plate 1.2m place.The each reserved row bolt box hole 5 of each box like structure 3 outer shroud place distance base plate 0.6m and 1.8m place.Often two bolt box holes 5 are put in arrangement, and for being arranged symmetrically with, distance center position is 9 °.This bolt box hole 5 diameter is 100mm.Bolt adopts 8.8 grades of plain bolts.
Circular floor plate 6 thickness is 100mm, and diameter is 16m.Diameter is reserved bolt box hole, 15.75m place.Circular floor plate 6 completes assembled with box like structure 3 by bolt.
Car elevator reserving hole 7 and People's Bank of China's elevator reserving hole 8 are set, car elevator, People's Bank of China's elevator and stair are installed.
Specific construction step is:
The first step: excavation of foundation pit, completes reversal of the natural order of things pipe-plate lining structure 2;
Second step: same layer box like structure 3 is put down foundation ditch inside in order;
3rd step: be fixed with bolts between the adjacent box like structure 3 of same layer, each box like structure 3 is bolted with pipe-plate lining structure 2;
4th step: install circular floor plate in same layer, realizes the assembled of circular floor plate and box like structure by bolt;
5th step: repeat the 3rd step and the 4th step, carries out bolt by reserved bolt box hole 5 between adjacent layer box like structure 3 and is connected and fixed;
5th step: the construction completing underground garage accessory structure.
Be more than an exemplary embodiments of the present invention, enforcement of the present invention is not limited thereto.
