Description
Technical Field
The invention belongs to the technical field of bridge engineering construction, and particularly relates to a semi-fabricated honeycomb steel beam and prestressed concrete combined capping beam and a construction process.
Background
With the rapidly growing demand of social economy, the construction of highway bridges and urban bridges in China is rapidly developed. At present, the construction of concrete bridges in China mainly adopts a cast-in-place concrete construction technology, precast concrete components are adopted in the upper structure part of a plurality of small and medium-span concrete bridges, and the cast-in-place concrete construction technology is mostly adopted in the lower structure of the bridge. The cast-in-place concrete construction technology has many disadvantages: in the process of pouring concrete, the quality of the formed concrete member cannot be guaranteed due to the technical restriction of construction managers; a large amount of manpower and material resources are needed in the manufacturing and installation processes of the template, and the quality of the concrete member is directly influenced by the template; the construction site needs to occupy surrounding urban roads, adverse effects are caused on road traffic, a large amount of noise pollution is generated, and the concept of green construction is not met; the construction period can not be guaranteed due to the influence of the environment and seasonal climate during the site construction. Precast concrete elements are used, mainly in superstructures with relatively small spans, i.e. precast concrete beam elements. The precast concrete construction technology is to transport the precast concrete components in different places or in factories to the site for installation, greatly shortening the construction period, reducing the loss of manpower and material resources, reducing the investment of cost and reducing the damage to the urban environment. However, the fully-prefabricated concrete member has the defects of heavy weight, huge potential safety hazard in the hoisting process, limitation on the length and the self weight of the prefabricated member due to the influence of factors such as transportation facilities, hoisting space and the like, and for this reason, a semi-fabricated concrete structure is adopted, namely, the prefabricated concrete member is manufactured in a different place or a factory, and then the rest of concrete is poured in a construction site, so that a better effect can be obtained. However, for some large-span beam-type members, large cantilever beam-type members, large-volume concrete members and the like, under the condition of limiting the self weight, size, rigidity, bearing capacity and the like of the members, the prefabricated concrete structure or member made of ordinary concrete can not meet the requirements of manufacturing, transporting, hoisting and constructing the structure or member, therefore, the prefabricated member made of ultra-high-performance concrete or steel plates is considered to be combined with the ordinary concrete to form a semi-fabricated concrete beam-type structure, and the expected purpose can be achieved. Therefore, the characteristics of material characteristics, low price, strong applicability and the like of the ultra-high performance concrete, steel and common concrete are comprehensively considered, and the semi-fabricated honeycomb steel beam and prestressed concrete combined capping beam and the construction process are provided.
