Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, the most right
The detailed description of the invention of the present invention is described in detail.It should be noted that, accompanying drawing of the present invention all uses simplification
Form and all use non-ratio accurately, only in order to convenient, aid in illustrating the mesh of the embodiment of the present invention lucidly
's.
As shown in Figures 1 to 6, car ramp and floor structure synchronous construction in the inverse work that the present invention provides
Method, including:
Step 1: the B0 layer of basement structure 100 of having constructed successively and B1 layer, refer to Fig. 7 to Fig. 9,
Basement structure 100 and lane plate 240, ramp side wall 250 junction arrange lane plate muscle 230 and reserving rib
220, and need to arrange temporary support 210 in top board appropriate position according to stress.Described temporary support 210
Need to be arranged at every layer of top board of basement structure 100 according to stress, executing of car ramp can be avoided
Territory, work area, therefore car ramp can be constructed continuously, and speed of application is faster than the construction method of routine, and relatively
Decrease the quantity of temporary support in prior art, the present invention need not changing during conventional reverse construction
Support, it is to avoid the foundation ditch secondary deformation that causes due to support replacement process, reduces the impact on foundation ditch surrounding enviroment.
The Rotating fields maintenance of step 2:B1 is to designing requirement, after template that Demolition Construction B1 layer is used and short framed bent,
The earthwork of excavation lower floor；Set up landing leg hands simultaneously in the car ramp position that B1 Rotating fields is corresponding and hang foot hands,
