Description
Technical Field
The utility model belongs to the building material field, concretely relates to quick location high waterproof ultra high performance concrete combination formula permanent formwork.
Background
The formwork project is developed along with the development of the concrete project, and has a long history at home and abroad. The permanent form is also called as a disposable consumption form, namely the form is not removed after the cast-in-place concrete structure is poured, wherein the permanent form is used as a protective layer or is combined into a common stress member after being overlapped with the cast-in-place structure. The method has the advantages of simplifying construction procedures, being simple and convenient to operate, improving labor conditions, not using or using few templates for supporting, saving the labor amount for template support and disassembly, accelerating construction progress and the like, and the main materials at present are steel, fiber reinforced plastics and the like. Although the production cost of the permanent template is higher than that of the traditional template, the total cost of the project using the novel permanent template is lower by comprehensively considering the factors of reducing the labor amount, reducing the material loss, shortening the construction period, enhancing the durability of the building, reducing the long-term maintenance cost, saving energy, protecting environment and the like. Therefore, the permanent template has good development prospect.
In the concrete structure under the chloride salt environment such as the ocean, the service life of the concrete is improved mainly by adopting seawater corrosion resistant concrete at present. However, in tidal zones and splash zones with particularly severe corrosion, the seawater corrosion resistant concrete structure is damaged early due to water flow scouring and dry-wet circulation, and the service life of the whole structure is influenced.
On the other hand, the seawater corrosion resistant concrete needs to adopt high-quality raw materials, particularly high-quality admixtures, and the availability is poor, so that the technical measure is difficult to adopt for many projects. There are also a lot of mass concrete structures, the interior of which does not need high resistance to chloride ions, but if seawater corrosion resistant concrete is used, it needs to be used entirely, resulting in waste of materials and high cost.
Considering that the poor structure durability under the marine environment is mainly internal steel bar corrosion and external concrete damage, in order to further improve the structure life under the marine environment, the idea of adopting an ultra-high performance concrete permanent template as the structure outer surface layer and adopting common concrete inside is provided, thereby reducing the manufacturing cost and the consumption of high-quality raw materials, and making the best use of things.
The ultra-high performance concrete is a high performance cement-based material developed at the end of the 20 th century, and is originally Reactive Powder Concrete (RPC) developed in France in 1993, and at present, the ultra-high performance concrete is mainly used for constructing highway bridges, maintaining and reinforcing structures and the like abroad.
The permanent formwork prepared from the ultra-high performance concrete can fully exert the advantages of the ultra-high performance concrete, solve the problem that the durability of the seawater corrosion resistant concrete in a tidal area and a splash area is low, is a good application of the ultra-high performance concrete and is a leading-edge subject in the world.
For the use of ultra high performance concrete as a permanent formwork for concrete structures, there is currently only a small amount of conceptual design and experimental research, which is also in the form of simple slab or monolithic formwork.
In actual engineering, except that some small-sized columns can adopt integral permanent templates, a large number of buildings such as piers, pier columns, retaining walls and the like cannot adopt the integral permanent templates due to large volume, and combined permanent templates are required. However, when the combined permanent formwork is used, the existence of the formwork joints cannot be avoided, the formwork joint part is a weak link of the stress of a structural member, the leakage caused by the weak link is also a main problem influencing the structural durability, and how to effectively solve the problem is one of the key problems of the use of the combined permanent formwork of the ultra-high performance concrete. In addition, whether the combined permanent formwork can be well connected with the internal concrete or not is avoided, an internal communication channel caused by hollowing is avoided, and the method is also very important for guaranteeing the durability of a concrete structure. Finally, how to quickly position the combined permanent template in the splicing process and greatly improve the construction efficiency is also a technical problem to be solved by technical personnel in the field.
