Description

A kind of contrary sequence method mechanization fall modular system

Technical field

This utility model relates to the realm of building construction, particularly to a kind of contrary sequence method mechanization fall modular system.

Background technology

Rapid development along with city, in Urban Building Construction field, particularly in the deep foundation pit construction in Soft Soil Layer geologic structure (such as Shanghai), reverse construction owing to its construction period is short, safety is high, be increasingly subject to people's attention the advantages such as the impact of buildings or structures around is little, has been applied in more and more engineering project.

Traditional contrary sequence method is to continue to backbreak out downwards certain space after digging designed elevation, utilize the space that this part is backbreak, the supporting construction of template system and template built by reinforced concrete structure (floor or beam) for cast-in-site, therefore interim bed course need to be poured into a mould at supporting surface, add cost；Meanwhile, owing to the reinforced concrete structure of cast-in-site requires time for maintenance, earth excavation can not be carried out during maintenance, this considerably increases the construction period of whole underground engineering.For shortening the construction period, later, it is developed a kind of contrary sequence method formwork hoisting device, the template system of whole contrary sequence method can be suspended on the reinforced concrete structure that last layer is poured into a mould by hanging apparatus, during reinforced concrete structure maintenance, can synchronize to carry out the excavation of lower floor's soil body, shorten the construction period of engineering to a certain extent；But owing to the template system of contrary sequence method can only be suspended on last layer reinforced concrete structure by hanging apparatus, if underground reinforced concrete structure is multiple structure (number of plies N >=2), often carry out one layer of construction to be required for the template system of hanging apparatus and contrary sequence method being dismantled and installing once, waste time and energy；Additionally, during the template demoulding and adjusting, owing to each suspension centre of template is to be suspended in the most separate hanging apparatus lower end, so being difficult to accomplish that template quick and stable moves, it usually needs through attempting can be only achieved the result of anticipation many times；On the other hand, due to different buildings, the story height of underground reinforced concrete structure differs greatly, the length of formwork hoisting device therefore used is the most different, the most same project, same deep-foundation pit engineering, owing to the function of every layer of underground concrete structure is different with role, the underground concrete structure of every layer is usually designed to different height, also imply that engineering project needs the formwork hoisting device of a lot of all sizes (length), considerably increase the early investment of engineering, increase Construction Cost virtually.

In sum, fall modular system and fall mould method thereof in existing reverse construction the most increasingly can not meet the high efficiency of Modern Construction, the requirement of low cost, in order to make the fall modular system of contrary sequence method be suitable for the different number of plies and the underground structure of the degree of depth and avoid mould method needing fall die device is repeatedly mounted and dismounted and drops die worker to make inefficiency owing to existing contrary sequence method drops, and cause substantial amounts of manpower, material resources and the waste of financial resources, therefore a kind of low cost of research and development, high efficiency contrary sequence method mechanization fall modular system and fall mould method thereof have become as the technical barrier that those skilled in the art are in the urgent need to address.
