Abstract
The present invention relates to a kind of precast concrete, belong to prefabricated reinforced concrete structure component technology field; Described precast concrete is linked together precast slab by connector; Described connector is reinforcing bar or light gauge cold-formed steel shape or steel bar girder; Described precast slab side has transverse concave groove, and the two sides of transverse concave groove are connected with reinforcing bar. The present invention, by improving the industrialized level of building structure, improves stress performance, saving resource.
Description
Technical field
The invention belongs to prefabricated reinforced concrete structure component technology field, relate in particular to one and be applicable to assembled integralThe precast concrete of structure.
Background technology
In monolithic reinforced concrete structure work progress, field fabrication is many, and wet trade is many, has a large amount of form work engineerings, scaffoldThe intermediate links such as engineering, waste resource, contaminated environment; Practitioner's quality, job site environment etc. affect very build gualityBring the problems such as building performance, quality and durability greatly. Change the present situation of monolithic reinforced concrete structure, should greatly developPrecast concrete. The primary structure member of precast concrete is made in factory, and production efficiency is high, quality good, jointResource-saving and the energy, be conducive to sustainable development. Adopting precast concrete is the direction of building industrialization development, is alsoThe direction of residence industrialized development.
In precast concrete, between prefabricated components, have horizontal joint, vertical abutment joint etc., the stress performance of seam has determinedIntegrality performance of the structure. Between existing precast concrete, seam connects comparatively complicated.
Summary of the invention
The invention provides a kind of precast concrete, can facilitate the installation of precast concrete to be connected with reinforcing bar,Improve the stress performance of seam, ensure structural integrity, improve building structure industrialized level.
For achieving the above object, the present invention proposes a kind of precast concrete, by connector, precast slab is connectedBe connected together; Described connector is reinforcing bar or light gauge cold-formed steel shape or steel bar girder, and connector two ends anchor into precast slabIn; Described precast slab side has transverse concave groove, and the two sides of transverse concave groove are connected with reinforcing bar, and reinforcing bar is through laterally recessedGroove, anchors in the concrete of transverse concave groove both sides. Size, the shape of transverse concave groove are determined according to stressed, making etc. Steel bar girderChord member is embedded in precast slab. The edge of a wing of light gauge cold-formed steel shape is embedded in precast slab, and its cross section can be C shape or ZShape or I-shaped etc.; For increasing globality, light gauge cold-formed steel shape has hole.
The precast slab medial surface of described precast concrete is male and fomale(M&F) or crude, to increase prefabricated coagulationNative and rear pouring concrete connection integrity.
The precast concrete that the present invention proposes can be for vertical members such as bodies of wall: precast concrete is perpendicularVertical, in the space surrounding at precast slab, casting concrete can form wall body construction; Or enclose at precast slabThe formation such as fill insulant material heat-preserving wall in the space becoming. The precast concrete that the present invention proposes can be for floor etc.In horizontal member: precast concrete is being kept flat, casting concrete in the space surrounding at precast slab, orIn the space that precast slab surrounds and its upper casting concrete formation floor member.
The present invention compared with prior art has following advantage.
Precast concrete of the present invention can reduce weight, convenient transport installation etc. Composition precast concretePrecast slab side has transverse concave groove, and transverse concave groove two sides are connected with reinforcing bar, can improve precast concrete with afterGlobality between pouring concrete, facilitates reinforcing bar between prefabricated components to connect. Precast concrete of the present invention has larger rigidity,Convenient transport, installation.
