Title:
LONG-SPAN PRE-STRESSED STRUCTURE FLOOR SLAB AND HIGH-PRECISION BUILDING FLOOR TOPPING ONE-TIME FORMING CONSTRUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/012759
Kind Code:
A1
Abstract:
Disclosed is a long-span pre-stressed structure floor slab and high-precision building floor topping one-time forming construction method. The method comprises the following steps: carrying out three-dimensional finite element modeling and finite element simulation analysis on a pre-stressed concrete structure, a high-formwork full frame body system and a concrete unit slab combination to obtain a post-cast strip sealing implementing solution, a concrete unit slab pre-stress tension solution, and a formwork solution, a pre-pressing solution and a form removal solution for a high-formwork full frame body; constructing a pre-stressed high-formwork; pre-pressing a full scaffold body according to the pre-pressing solution; carrying out one-time forming construction on a structural floor topping; carrying out pre-stressed construction on a concrete unit slab; and determining a reasonable slab combination sequence in order to carry out post-cast strip partitioning combination sealing according to the post-cast strip sealing implementing solution. The long-span pre-stressed structure floor slab and high-precision building floor topping one-time forming construction method provided by the present invention can lower construction costs and can effectively shorten the construction period.
