Abstract
The invention relates to a precast concrete member, belonging to the technical field of precast reinforced concrete structural members. According to the precast concrete member, precast concrete slabs are connected together by connecting members; the connecting members are reinforcing steel bars or cold-bent thin-walled steel or reinforcing steel bar trusses; transverse grooves are formed in the side edge of each precast concrete slab, reinforcing steel bars are connected to the two side faces of each transverse groove. The precast concrete member has the advantages that the level of industrialization of a building structure can be increased, the stress property is improved, and resources are saved.
Description
Technical field
The invention belongs to prefabricated reinforced concrete structure component technology field, relate in particular to a kind of precast unit that is applicable to 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 engineerings, scaffolding work, waste resource, contaminated environment; Practitioner's quality, job site environment etc. are very large on build guality impact, bring the problems such as building performance, quality and durability.Change the present situation of monolithic reinforced concrete structure, should greatly develop precast concrete.The primary structure member of precast concrete is made in factory, and production efficiency is high, quality good, and saving resource and the energy, be conducive to sustainable development.Adopting precast concrete is the direction of industrialization of construction industry development, is also the direction of housing industrialization development.
In precast concrete, between prefabricated units, have horizontal joint, vertical abutment joint etc., the stress performance of seam has determined integrality performance of the structure.Between existing precast unit, seam connects comparatively complicated.
Summary of the invention
The invention provides a kind of precast unit, can facilitate the installation of precast unit to be connected with reinforcing bar, improve the stress performance of seam, guarantee structural integrity, improve building structure industrialized level.
For achieving the above object, the present invention proposes a kind of precast unit, by connector, precast concrete plank is linked together; Described connector is reinforcing bar or light gauge cold-formed steel shape or steel bar girder, and connector two ends anchor in precast concrete plank; Described precast concrete plank side has transverse concave groove, and the two sides of transverse concave groove are connected with reinforcing bar, and reinforcing bar, through transverse concave groove, anchors in the concrete of transverse concave groove both sides.Size, the shape of transverse concave groove are determined according to stressed, making etc.The chord member of steel bar girder is embedded in precast concrete plank.The edge of a wing of light gauge cold-formed steel shape is embedded in precast concrete plank, and it is Z-shaped or I-shaped etc. that its cross section can be C shape; For increasing globality, light gauge cold-formed steel shape has hole.
The precast concrete plank medial surface of described precast unit is male and fomale(M&F) or crude, to increase precast concrete and rear pouring concrete connection integrity.
The precast unit that the present invention proposes can be for vertical members such as bodies of wall: precast unit is erect, and in the space surrounding at precast concrete plank, concreting can form wall body construction; Or in the space surrounding at precast concrete plank, fill insulant material etc. forms heat-preserving wall.The precast unit that the present invention proposes can be in the horizontal members such as floor: precast unit is being kept flat, concreting in the space surrounding at precast concrete plank, or in the space surrounding at precast concrete plank and its on concreting form floor member.
The present invention compared with prior art has following advantage.
Precast unit of the present invention can reduce weight, convenient transportation installation etc.The precast concrete plank side of composition precast unit has transverse concave groove, and transverse concave groove two sides are connected with reinforcing bar, can improve the globality between precast concrete and rear pouring concrete, facilitates reinforcing bar connection between prefabricated units.Precast unit of the present invention has larger rigidity, convenient transportation, installation.
