Description
Technical field
The invention belongs to building material field, be specifically related to a kind of ultra-high performance concrete cylinder permanent template and preparation thereof
Method.
Background technology
When carrying out concreting, need to use template to obtain the concrete component of design shape.The most all adopt
By templates such as wooden model, punching block, aluminium alloy moulds, installation form, concrete before casting concrete, is needed to need after reaching intensity to remove mould
Plate.Form work engineering is the important component part of concrete structure construction, long construction period, costly.
After World War II, for improving speed of application, developing permanent template, template is not removed, as the one of structure after using
Part uses.Permanent template, due to its easy construction, is saved the duration, has been started progressively to be applied in all kinds of concrete works.
Not only there is the support molding function meeting casting concrete, the member-retaining portion in building structure can be become again, both may participate in and built
Build thing load-bearing, stress performance and the serviceability of structure can be improved again.According to the needs of building, permanent formwork can also be attached
Band have waterproof, insulation, heat insulation, insulate against sound, decorate, improve durability, reduce the function such as the number of turnover, accomplish one-shot forming, save
But the operation such as sand finish, levelling, secondary decoration, waterproof thermal-insulated process, surface layer fitting-up, thus work can be greatly saved
Journey construction momentum and decoration, decoration cost.Owing to permanent formwork need not form removal, can save a large amount of due to form removal with have bad luck
Time spent by template and expense, highly shortened the duration, reduces construction costs, and reduces the labor intensity of workman.
The most external permanent template mainly has following several form: (1) ICT heat insulation formwork, is to assist at american concrete
A new technique of lower positive application can be promoted, and define " the new concrete structure residential body with technique as core
System ".(2) SRC structure construction is without support shuttering, this be one be exclusively used in that steel composite construction (SRC) constructs permanent
Template, owing to being made by factory process now, production efficiency is high, and Product Precision is ensured, and without supporting.(3) prefabricated height
Strength mortar thin-walled template, by the exploitation of Xi Song company of Japan, inner side is provided with shear connector and is processed to form male and fomale(M&F), watering through scene
Build concrete, it is ensured that molding integrated member.(4) concrete prefabricated column mould, high-strength for adaptation by the exploitation of great Lin group company of Japan
Concrete requires and the concrete prefabricated column mould of research design, and its molding mode has two kinds: centrifugal casting and the inflow method of forming.
Since the nineties in 20th century, China's architectural structure system achieves huge development, along with skyscraper and superelevation
A large amount of constructions of layer building, and the developing rapidly of large-scale capital construction, urban transportation and highway, the building of China
Construction technology makes great progress, the template of Building Trade in China the most constantly Introduced From Abroad, scaffold system, and develops
All kinds of permanent new type formworks, main research has: (1) uses FRP(fiber-reinforced polymer) as concrete works forever
The feature that property template, fiberglass tensile strength and shock resistance are high for a long time effectively compensate for the feature that concrete tensile strength is low,
The rupture strength of beam can be increased substantially.(2) steel-wire-net reinforced concrete thin plate template, is the steel fiber reinforced concrete structure of a kind of broad sense
Part, intensity is high, Elastoplastic Performances in Simulation is high, and durability is high.(3) Ribbed shuttering steel concrete compoboard, overcomes widely used
The deficiency of version that combines with steel-concrete combination beam as bed die of profiled sheet, improve dramatically
The ductility of component.
In recent years, along with the development of ultra-high performance concrete, the most also carry out ultra-high performance concrete permanent template
Research, the RPC of the most more research.
2005, Beijing Jiaotong University's clock prunus mume (sieb.) sieb.et zucc. forever comprcssive strength based on RPC superelevation, activity powder is proposed
End concrete permanent template, the compressive mechanical property of its component is superior, and construction technology has had the biggest improvement, the tension of single member
Mechanical property in terms of anti-folding has been short of, and requires further improvement.
Mixing of steel fiber in ultra-high performance concrete, can effectively overcome High Strength Concrete Under Compressive Cyclic Loading intensity high and tension,
The defect of fracture resistance difference.Harbin Institute of Technology and Institutes Of Technology Of Changsha all carried out the material of steel fibre high performance concrete
Experiments of Machanics, have higher Research Significance and future in engineering applications.
Ultra-high performance concrete permanent template molding at present mainly has two ways, centrifuging and casting method.
But during centrifugal forming ultra-high performance concrete permanent template, owing to ultra-high performance concrete not having coarse aggregate
Stopping, the steel fibre that density is bigger can be concentrated the outer layer being distributed in permanent template under the action of the centrifugal, even cause steel fibre big
Amount is exposed to outer surface, and corrosion is so that the performance such as resistance fragility, toughness and durability of ultra-high performance concrete reduces.With
Time, the steel fibre of uneven distribution can cause the mechanical heterogeneity of ultra-high performance concrete component, and outer layer permanent template mixes
Solidifying soil globality is destroyed, and increases the uncertain factor of element bearing capacity, the component strength design that impact is relevant, also drops simultaneously
Low component shearing resistance and the ability of Bend.These problems above-mentioned, can make the ultra-high performance concrete component being centrifuged use
Time safety, durability or even bearing capacity can not reach intended purpose, the safety of Structural Engineering is threatened.
During casting method molding, owing to ultra-high performance concrete degree of compaction is the highest, the ultra-high performance concrete permanent template demoulding
Rear inner surface unusual light, during use permanent template with after water the imperfect bonding of wadding weft variation, can frequently result in bi-material
Can not collaborative work, cracking load is too low, it is impossible to gives full play to the performance of material, occurs crack too early, causes durability to decline,
Especially under cyclic reverse loading, both each work even more serious, and mechanical property is substantially reduced.
Summary of the invention
For solving problem above, the invention provides a kind of ultra-high performance concrete cylinder permanent template to improve concrete
Permanent template and after water the cohesive force between core concrete, thus improve the overall performance of structure, improve its intensity and length
