The combined member provided by the invention is particularly applicable to island port construction, a cross-sea bridge and other projects under high temperature, high humidity and high salinity severe conditions.
Description
Technical field
The invention belongs to technical field of civil engineering, be specifically related to a kind of structural element, the combined member be particularly made up of stainless steel tube and coral self-compacting concrete, the islands and reefs be particularly useful under high temperature, high humidity, high salt mal-condition build the engineering such as port, bridge spanning the sea.
Background technology
Along with the development and utilization of China's marine resources, move towards off-lying sea, deep-sea become ocean engineering development inexorable trend.Traditional encased structures is widely used in the field such as highrise building, bridge engineering, but under off-lying sea, deep sea condition, there is the present situation of following several respects: first, at high temperature, high humidity, hypersaline environment, traditional steel pipe need carry out preservative treatment, and the complex conditions of off-lying sea makes preservative treatment and maintenance cost very high; Secondly, lack in off-lying sea Under Concrete aggregate materials, long distance transportation cost is high; Finally, in traditional concrete-filled steel tube construction, need to carry out vibration compacting to the concrete of cast, need more construction machinery.
Compared with carbon steel, stainless steel material has good decay resistance and durability, make structural safety reliable, solid durable and later maintenance cost is low, but stainless steel structure also has the shortcoming that initial stage cost is high.
Off-lying sea islands and reefs there is a large amount of coral reef resources, therefore coral sand or coral reef fragment, cement and other cementitious material mixings can be utilized to become coral reef concrete, common coral reef concrete strength is lower, durability is poor, and due to its poor fluidity, need when filling steel pipe to vibrate, complicated and the risk having bleeding to emanate of construction, therefore, is not suitable for using under the off-lying sea mal-condition of high temperature, high humidity, high salt separately.
Summary of the invention
The present invention seeks to the above-mentioned shortcoming and defect in order to overcome existing common steel tube concrete and the existence of coral reef concrete, a kind of stainless steel tube-coral self-compacting concrete combined member is provided.This component is specially adapted to the off-lying sea islands and reefs port engineering construction of high temperature, high humidity, high salt and raw material deficiency.Component has that intensity is high, wind resistance behaviour at sea is strong, good endurance, easy construction and the feature such as maintenance cost is low.
Stainless steel tube provided by the invention-coral self-compacting concrete combined member, comprises the coral self-compacting concrete of filling in stainless steel tube and pipe.Described coral self-compacting concrete utilizes coral sand and coral reef fragment respectively as fines and coarse aggregate, and cement, flyash is as cementitious material, and polycarboxylic acid series high efficiency water reducing agent, as Admixture, uses water mixing to form.Utilize concrete pump, above-mentioned coral self-compacting concrete is poured in stainless steel tube, without the need to vibrating.
Top in described stainless steel tube adopts high-strength mortar plug to bind.
Described stainless steel tube can be pipe, square tube or rectangular tube.
Described stainless steel tube length is whole time shorter, and two ends are by welding shutoff; Can be many with connecting when length is longer, connected mode comprises welding, riveted joint.
Described stainless steel tube-coral self-compacting concrete combined member is mainly compressed member, and arrangement form can be straight column structure or arc arced configuration.
advantage of the present invention and effect:
The composite component that the present invention is made up of stainless steel tube and coral self-compacting concrete, its advantage to give full play to respective material behavior, and intensity is high, and corrosion resistance is strong, and construction cost is low.
Described coral self-compacting concrete aggregate is coral sand or coral reef fragment, improves islands and reefs stock utilization to greatest extent, reduces construction cost.
Described coral self-compacting concrete good fluidity, avoids the process of vibrating in work progress, is applicable to long tube construction, improves speed of application, ensured construction quality.
Described stainless steel tube corrosion resistance is strong, improves structure durability, reduces later maintenance cost.
