Description

A fast positioning high waterproof and ultra high performance concrete combined permanent formwork

technical field

The utility model belongs to the field of building materials, in particular to a fast-positioning high-waterproof and ultra-high-performance concrete combined permanent formwork.

Background technique

Formwork engineering has developed along with the development of concrete engineering and has a long history at home and abroad. The permanent formwork, also known as the one-time consumption formwork, means that the formwork will not be removed after the cast-in-place concrete structure is poured. It has the advantages of simplified construction process, easy operation, improved working conditions, no or less use of formwork support, saving of formwork support and disassembly, and accelerated construction progress. At present, the main materials are steel, fiber reinforced plastics, etc. Although the production cost of permanent formwork is higher than that of traditional formwork, considering factors such as the reduction of labor, the reduction of material loss, the shortening of construction period, the enhancement of building durability, the reduction of long-term maintenance costs, energy saving and environmental protection and other factors, the use of new permanent formwork The overall engineering cost of the formwork is lower. Therefore, the permanent template has a good development prospect.

For concrete structures in chloride environments such as the ocean, seawater corrosion-resistant concrete is mainly used to improve their service life. However, in the tidal zone and splash zone where corrosion is particularly severe, due to water scouring and dry-wet cycle, the seawater corrosion-resistant concrete structure will be damaged earlier, affecting the overall life of the structure.

On the other hand, due to the poor availability of high-quality raw materials, especially high-quality admixtures, for seawater-resistant concrete, it is difficult to adopt this technical measure in many projects. There are also many large-volume concrete structures that do not need high chloride ion resistance inside, but if seawater corrosion-resistant concrete is used, all of them need to be used, resulting in waste of materials and higher construction costs.

Considering that the poor structural durability in the marine environment is mainly due to the corrosion of the internal steel bars and the damage of the external concrete, in order to further improve the structural life in the marine environment, it is proposed to use the permanent formwork of ultra-high performance concrete as the outer layer of the structure, and the internal use of ordinary concrete. Reduce the cost and consumption of high-quality raw materials, and make the best use of everything.

Ultra-high-performance concrete is a high-performance cement-based material developed at the end of the 20th century. It was originally reactive powder concrete (RPC) developed in France in 1993. At present, ultra-high-performance concrete is mainly used in the construction of highways and bridges abroad, structural maintenance and reinforcement.

The use of ultra-high-performance concrete to prepare permanent formwork can give full play to the advantages of ultra-high-performance concrete and solve the problem of low durability of seawater-resistant concrete in tidal and splash zones. It is a good use for ultra-high-performance concrete applications. , is also a frontier topic in the world.

As for the permanent formwork of ultra-high performance concrete used as concrete structure, there are only a few conceptual designs and experimental studies, and its form is only a simple plate or integral formwork.

In actual engineering, except for some small-sized columns that can use integral permanent formwork, a large number of bridge piers, piers, retaining walls and other structures are too large to use integral permanent formwork, and combined permanent formwork must be used. However, when the combined permanent formwork is used, it is inevitable that there will be formwork joints. The formwork joints are the weak link of the structural members, and the leakage caused by them is also the main problem affecting the structural durability. How to effectively solve this problem The question is one of the key issues of whether the combined permanent formwork of ultra-high performance concrete can be used. In addition, whether the combined permanent formwork can have a good connection with the internal concrete to avoid voids and cause internal communication channels is also crucial to ensuring the durability of the concrete structure. Finally, how to quickly locate the combined permanent formwork and greatly improve the construction efficiency during the splicing process is also a technical problem that needs to be solved by those skilled in the art.
