Summary of the invention
The invention provides the method for attachment of a kind of easy construction, precast concrete plank that stress performance is good.The method of attachment of the precast concrete plank that the present invention proposes can improve the globality of assembled monolithic concrete structure, improves the performance of building structure, improves industrialization of construction industry level.
The method of attachment of the precast concrete plank that the present invention proposes is characterised in that, described precast concrete plank side is embedded with abundant anchoring, exposed portions serve is Semicircular reinforcing bar, on described semicircular reinforcing bar, hang with transverse reinforcement, transverse reinforcement can move, rotate on semicircular reinforcing bar like this, freely adjust position, facilitate precast concrete plank transportation, lifting, facilitate transverse reinforcement location; Transverse reinforcement is concentrated and is hung on semicircular reinforcing bar in factory or building site, reduces job site steel project; After precast concrete plank installation in position, preset clearance inside lap by transverse reinforcement between precast concrete plank, fixing, installs template in preset clearance bottom, and in preset clearance, precast concrete plank is linked to be entirety by concreting; Or install template in preset clearance bottom, in preset clearance, form precast concrete superimposed sheet with precast concrete plank top concreting.Transverse reinforcement is connected reliably with semicircular reinforcing bar, guarantees that transverse reinforcement gives full play to intensity.
The method of attachment of precast concrete plank that the present invention proposes is characterised in that, described transverse reinforcement end upwards bends 90
., or bending 135
., or other angles, can increase the anchorage length of transverse reinforcement in rear pouring concrete, increase the connection integrity between precast concrete plank.In order further to improve the connection integrity of precast concrete plank, in described transverse reinforcement corner, longitudinal reinforcement is set.
The method of attachment of precast concrete plank that the present invention proposes is characterised in that, described precast concrete plank side has transverse concave groove, and described transverse reinforcement is at transverse concave groove place, or described transverse reinforcement is in the projection between transverse concave groove.By transverse concave groove is set, connection integrity between pouring concrete and precast concrete after can improving between precast concrete plank, and the lap length of transverse reinforcement some at transverse concave groove place, reduce preset clearance, thereby reduce template amount.
The method of attachment that the present invention proposes can be used for reference the connection for body of wall.
Technical characterstic of the present invention and advantage.
(1) transverse reinforcement of the present invention hangs over precast concrete plank side, and position is freely adjusted in translation within the specific limits, rotation, facilitates transportation, the installation of precast concrete plank, facilitates reinforcing bar location, connection etc. between precast concrete plank.
(2) there is transverse concave groove precast concrete plank of the present invention side, improves the binding ability of new-old concrete.
(3) transverse reinforcement of the present invention is linked on precast concrete plank in factory, and the part reinforced bar engineering of job site is transferred to factory, improves industrialization of construction industry level.
