Embodiment 1

[0026] Refer to attached picture. An interlocking, crack-proof and seepage-proof permanent formwork of this embodiment includes five first panels 1 and two second panels 2 . The cross-sections of the second panel 2 and the first panel 1 are concave with walls on both sides, and the outer side of the wall on one side of the first panel 1 has a connecting groove 11 opening in the opposite direction to the concave, and its size can be the same as The walls 20 on both sides of the second panel are plug-fitted and are plug-fitted with the wall 12 on the other side of the first panel.

[0027] There are several grooves 3 distributed on the inner surface of the first panel 1 and the second panel 2; the connection groove 11 of the first panel adjacent to the second panel is buckled on the adjacent second panel wall 20, and the adjacent Among the two first panels 1, the connecting groove of the first panel far away from the second panel 2 is buckled on the wall 12 without the connecti...

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...
