A kind of mold-reducing system and mold-reducing method by reverse method

Abstract

The invention discloses an inverse method die-lowering system and die-lowering method. The die-lowering system includes a die plate support structure and a hoisting mechanism that are successively arranged on each structure column from the bottom to the top, a truss structure, a floor die plate and a column cap die plate are successively erected on the die plate support structure, one side of the column cap die plate is connected with the floor die plate, and the other side of the column cap die plate is connected with the structure column. Compared with the prior art, the inverse method die-lowering system is advantageous in that (1) scaffold erection can be prevented, the mechanical device is simple, the construction operation is less, the operation is simple and rapid, and the construction period is effectively shortened; (2) the over excavation depth is greatly reduced, the work environment is improved, and the ground pit construction security is improved; (3) the die-lowering system is convenient to detach, one column distance is divided into one unit, so that the local and overall area floor board construction is facilitated; and (4) the detached die-lowering system can be repeatedly used, the material utilization rate is improved, and the construction cost is saved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a mold-reducing system and a mold-reducing method of the reverse method. Background technique [0002] In the process of reverse construction on soft soil foundation, there are two main types of traditional formwork systems for horizontal structures: short-bent frame formwork system and cushion grid formwork system. Among them, the short-bracket formwork system needs to reserve a short-row space, and the resulting earthwork over-excavation will affect maintenance deformation and bring certain safety hazards. At the same time, the narrow and harsh construction conditions also cause a lot of inconvenience to the demolition personnel. When the cushion grid formwork system is used, it needs to be close to the earth to be excavated, and the removal of the formwork must be carried out in conjunction with reverse excavation, which puts forward high requirements for construction safe...

Problems solved by technology

Among them, the short-bracket formwork system needs to reserve a short-row space, and the resulting earthwork over-excavation will affect maintenance deformation and bring certain safety hazards. At the same time, the narrow and harsh construction conditions also cause a lot of inconvenience to the demolition personnel.

When the cushion grid formwork system is used, it needs to be close to the earth to be excavated, and the removal of the formwork must be carried out in conjunction with reverse excavation, which puts forward higher requirements for construction safety, and at the same time, there is inevitably a problem of material waste

[0003] In addition, in the existing reverse formwork lowering system, the formwork is hung on the upper floor through the boom, and the boom is pulled by the electric hoist, and the lifting bolts in the boom are continuously adjusted to make the formwork system fall downward. The formwork system needs to be laid There are a large number of reserved holes for suspenders, and there are many mechanical spreaders such as suspenders and electric hoists, which have high requirements for the site layout of lifting points. Especially when the construction area is large, the adjustment of a large number of lifting bolts and the traction of electric hoists Synchronization and other issues bring great trouble to the actual operation
