Interlocking dismountable anti-cracking anti-seepage permanent template

Abstract

The invention provides an interlocking dismountable anti-cracking anti-seepage permanent template. A column of second panels and multiple columns of first panels are connected to form a template, the cross sections of each first panel and each second panel are of a concave shape the two sides of which are provided with walls, and each first panel and each second panel are made by adopting the following materials: ultra high toughness cementitious composite (UHTCC), a non-metal fiber woven mesh and a short fiber combined reinforced cementitious composite and a steel wire mesh and short fiber combined reinforced cementitious composite. The interlocking dismountable anti-cracking anti-seepage permanent template disclosed by the invention is used as a template in a pouring stage and is a permanent template after pouring is completed, dismounting and turnover costs are eliminated, and the problems of dismounting in template construction of a hydraulic structure, a seaport structure and a bridge, culvert and tunnel and utilization rate are solved. The interlocking dismountable anti-cracking anti-seepage permanent template disclosed by the invention has the characteristics of high stretching drawability, high crack control ability, high damage tolerance and strong energy absorption capability, anti-chlorine ion permeability and water resisting property of the interlocking dismountable anti-cracking anti-seepage permanent template disclosed by the invention are far better than those of common concrete, and the durability and service life of a concrete structure can be obviously improved.

Description

technical field [0001] The patent of the present invention belongs to a building formwork, specifically a high-durability permanent formwork mainly used in hydraulic structures, harbor and sea structures, bridges and culverts, etc. It is used as a formwork during the pouring stage, and is also used as a structure after pouring and molding The protective plate and outer protective layer. Background technique [0002] At present, in the domestic construction field, building structures such as hydraulic structures, harbor and sea structures, bridges and culverts and tunnels usually use wooden formwork, steel formwork and other formwork, which have disadvantages such as large consumption, inconvenient disassembly and assembly, high turnover cost, and low utilization rate. In the traditional structure, the ordinary concrete surface is naturally exposed, and its durability is low. At the same time, design with crack resistance as the control condition is an important feature that...

Problems solved by technology

At the same time, design with crack resistance as the control condition is an important feature that distinguishes hydraulic structures and 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 and performance. Seriously, it may even affect the safe operation of the structure
