Description
Technical field
The invention belongs to prefabricated reinforced concrete structure component technology field, particularly relate to a kind of precast concrete suitable in cast in place and precast construction.
Background technology
In monolithic reinforced concrete structure work progress, field fabrication is many, and wet trade is many, has the intermediate links such as a large amount of form work engineering, scaffolding work, wastes resource, contaminated environment；Practitioner's quality, job site environment etc. are very big on build guality impact, bring the problems such as building performance, quality and durability.Change the present situation of monolithic reinforced concrete structure, precast concrete should be greatly developed.The primary structural member of precast concrete makes in factory, and production efficiency is high, quality is good, saves resource and the energy, is conducive to sustainable development.Adopting precast concrete is the direction that building industrialization develops, and is also the direction of housing industrialization development.
Having horizontal joint, vertical abutment joint etc. in precast concrete between precast concrete, the stress performance of seam determines integrality performance of the structure.Existing precast concrete seam connects complex, and globality is poor.
Summary of the invention
The invention provides a kind of precast concrete, installation and the bar connecting of precast concrete can be facilitated, improve the stress performance of seam, it is ensured that the globality of structure, improve building structure industrialized level.
For reaching above-mentioned purpose, the present invention proposes a kind of precast concrete, and this precast concrete is precast reinforced concrete structure, and side has longitudinal fluting, there is concrete thin plates longitudinal fluting both sides, are connected with string or the above transverse steel of string between concrete thin plates；Adopt transverse steel to connect concrete thin plates, the globality between precast concrete and rear pouring concrete can be improved；Transverse steel, in longitudinal fluting, conveniently makes and transport；Convenient in longitudinal fluting arrange that precast concrete is connected together by other reinforcing bars, for instance by placing reinforced steel bar ring and mutually joining with described transverse steel, casting concrete.Link one or more steel bar girders or one or a web holes light gauge cold-formed steel shape at longitudinal fluting both sides concrete thin plates, identical technique effect can be reached.The chord member of steel bar girder is embedded in the concrete thin plates of described longitudinal fluting both sides, and web member connects concrete thin plates.The edge of a wing of light gauge cold-formed steel shape is embedded in the concrete thin plates of longitudinal fluting both sides, and its cross section can be that C shape is Z-shaped or I-shaped etc..Being provided with vertical muscle in described longitudinal fluting, vertical muscle is inside transverse steel or steel bar girder.Described vertical muscle hangs with ring steel reinforced bar；Ring steel reinforced bar can be movable comparatively freely on vertical muscle, can be hidden in longitudinal fluting in transport, hoisting process.After precast concrete hoisted in position, then ring steel reinforced bar is fixed.
Described precast concrete has longitudinal bore, it is possible to be square hole, circular hole etc..In order to water in the globality of longitudinal bore inner concrete after increasing, between longitudinal bore and longitudinal fluting, have horizontal hole.Or have horizontal hole between the longitudinal fluting of precast concrete both sides.
There is horizontal concrete slab in the longitudinal fluting of described precast concrete, connect longitudinal fluting both sides concrete thin plates；For pouring concrete and the globality of precast concrete after increasing, horizontal concrete slab has hole.Hole on the horizontal concrete slab of described vertical muscle traverse.
The present invention compared with prior art has the advantage that.
There is longitudinal fluting the precast concrete side of the present invention, is connected with transverse steel between longitudinal fluting, connects concrete thin plates, can improve the globality between precast concrete and rear pouring concrete；Transverse steel, in longitudinal fluting, conveniently makes and transport.Hanging with ring steel reinforced bar between precast concrete, ring steel reinforced bar can be movable comparatively freely on vertical muscle, can be hidden in longitudinal fluting, convenient construction in transport, hoisting process；And ring steel reinforced bar location is convenient.
