Description
Technical field
The present invention relates to a kind of carbon fiber mesh enhancing concrete to exempt to tear column mould and preparation method thereof open, belongs in civil engineering
Composite column structure technical field.
Background technology
In recent years, fast-developing China's economic further improves the aesthetic level of the people, the regular building of tradition
Style is difficult to meet the requirement of pluralism development, pursues the personalization of building and becomes a new demand.To prick heartily
Di De is a part of high-level architect of representative, is good at and courageously receives domestic market high praise with space and geometry,
Guangzhou grand theater, Nanjing centers Qing Ao etc. are all the masterpieces of this kind of great building individuation.And curve is architect's design of expression
How the important means of theory carries out formwork to pour being a difficulty in traditional cast-in-place construction method to these complicated curved components
Topic, the difficulty of construction often greatly constrain architect and design the space played.
In addition, there is pitted skin, honeycomb, dew muscle and other issues more due to component surface caused by leakage in cast-in-place construction method
Generally, overall structure quality is difficult to ensure, seriously affects structure durability.Meanwhile live formwork occupies a large amount of structure and makes
Valence and labour dosage, long construction period, low production efficiency, labor intensity are high, also generate a large amount of building wastes.Exempt from form removal
Plate no longer carries out template dismantlement work after the completion of concrete structure pouring, be different from the spy that plywood form uses temporarily
Point, non-dismantling formwork are not only the shaping jig of casting concrete and the primary structure member of service stage.It is mixed with after-pouring
Xtah Crude Clay structure is compound and is combined as common primary structure member, can make full use of material, has and simplifies working procedure, improves labour item
Part, the advantages that reducing shuttering supporting, saving labo r usage and accelerate construction progress.Prefabrication template-scene of non-dismantling formwork
The build model of casting concrete can improve overall structure construction quality and durability, be to meet national building industrialization development
Direction alleviates building trade labor shortage problem, practices the Feasible Mode of sustainable development view.
UHPC (ultra-high performance concrete) full name is ultra-high performance concrete, is with cement, mine
The strong toughening of superelevation of the raw materials such as object admixture isoreactivity dusty material, fine aggregate, additive, high-strength steel fibre, water production is mixed
Solidifying soil has high intensity, high tenacity, high-durability, high crack-resistant, shrinkage and creep small and the excellent spy such as good volume stability
Property, but cost is higher, can generally reach the decades of times of normal concrete, constrains its further application development.
China discloses a kind of ultra-high performance concrete column permanent template and its preparation side in careful patent CN106223544A
Method, the template include open column shape ultra-high performance concrete layer, the steel reinforcement cage being built in ultra-high performance concrete layer, and super
The inner surface of high performance concrete layer has dent of the depth not less than 5mm to pour core coagulation with after to enhance ultra-high performance concrete
Cohesive force between soil.Using the higher intensity of ultra-high performance concrete and compactness to improve the performance of component and durable
Property.But its steel reinforcement cage is placed in ultra-high performance concrete, and core is plain concrete, thus ultra-high performance concrete layer is thicker, at
This is not low, and cover to reinforcement minimum only has 10mm, and the influence to its durability leaves a question open.In addition, the template and its system of its announcement
Preparation Method can not prepare the column non-dismantling formwork with complex model just for cylinder or square column section.
