Keel embedded-buckled assembling anti-cracking anti-seepage permanent cylinder shuttering

Abstract

The invention discloses a keel embedded-buckled assembling anti-cracking anti-seepage permanent cylinder shuttering, which comprises shuttering corner panels and connecting pieces. The invention can be used as a cylinder shuttering in cylinder pouring phases of structures such as industrial and civil building structures, hydraulic structures, harbor structures, and the like, and can be used as a protection plate and an outer protective layer of the structures after pouring molding, and bear a part of loads. The shuttering provided by the invention can be made of the following different kinds of materials: ultrahigh-toughness cement-based composite materials UHTCC, cement-based composite materials reinforced by nonmetal fiber meshes combined with short fibers, cement-based composite materials reinforced by steel wire meshes combined with short fibers, and the like, and has the characteristics of simple manufacturing, convenient usage, high endurance, and crack extension controllability.

Description

technical field [0001] The patent of the invention belongs to a building formwork, specifically a high-durability permanent formwork mainly used for columns of industrial and civil building structures, hydraulic structures, and harbor and sea structures, and used as a formwork in the pouring stage , after pouring and molding, it can also be used as the protective plate and outer protective layer of the structure, and bear part of the structural load at the same time. Background technique [0002] At present, in the field of domestic construction, the columns of industrial and civil building structures, hydraulic structures, and harbor and sea structures usually use wooden formwork, steel formwork and other formwork, which has the disadvantages of large consumption, inconvenient disassembly and assembly, high turnover costs, and low utilization rate. low disadvantages. Durability has always been one of the main problems faced by reinforced concrete structures. In the tradit...

AI Technical Summary

Problems solved by technology

In the traditional structure, the surface of ordinary concrete is naturally exposed, and its durability is low. At present, about 50% of the houses in my country have entered the aging stage, that is, 2.34 billion square meters of buildings are facing durability problems.

In addition, designing with crack resistance as the control condition is an important feature that distinguishes hydraulic structures, port and sea structures, etc. from other types of building structures. The problem of easy cracking of ordinary concrete will not only affect the normal work of hydraulic structures, but also affect their durability. performance and service life, and even affect the safe operation of the structure
