Description
Technical field
The invention belongs to building structure technology field, particularly relate to a kind of method of attachment of the precast concrete plank for fabricated assembly overall concrete structure.
Background technology
Precast concrete is applicable industrialized form of structure, is the direction of housing industrialization development.Joint's connection fabrication in precast concrete between prefabricated units determines integrality performance of the structure.Existing precast concrete node is generally the weak link of structure, have impact on stress performance, and work progress is comparatively complicated.
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 feature of the method for attachment of the precast concrete plank that the present invention proposes is, described precast concrete plank side is embedded with abundant anchoring, exposed portion is Semicircular reinforcing bar, described semicircular reinforcing bar hangs with transverse reinforcement, such transverse reinforcement can move, rotate on semicircular reinforcing bar, freely adjust position, facilitate precast concrete plank to transport, lift, facilitate transverse reinforcement to locate; Transverse reinforcement is concentrated in factory or building site and is hung on semicircular reinforcing bar, reduces job site steel project; After precast concrete plank installation in position, by the preset clearance inside lap of transverse reinforcement between precast concrete plank, fix, install template in preset clearance bottom, 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 and semicircular bar connecting reliably, ensure that transverse reinforcement gives full play to intensity.
The feature of the method for attachment of the precast concrete plank that the present invention proposes is, described transverse reinforcement end upwards bends 90
., or bending 135
., or other angles, the anchorage length of transverse reinforcement in rear pouring concrete can be increased, increase the connection integrity between precast concrete plank.In order to improve the connection integrity of precast concrete plank further, longitudinal reinforcement is set in described transverse reinforcement corner.
The feature of method of attachment of the precast concrete plank that the present invention proposes is, described precast concrete plank side has transverse concave groove, described transverse reinforcement at transverse concave groove place, or in the projection of described transverse reinforcement between transverse concave groove.By arranging transverse concave groove, 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, thus reduce template amount.
The method of attachment that the present invention proposes can use 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, can translation within the specific limits, rotation, freely adjust position, facilitate the transport of precast concrete plank, installation, facilitate that the reinforcing bar between precast concrete plank is located, connection etc.
(2) there is transverse concave groove precast concrete plank side of the present invention, 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.

Detailed description of the invention
Below in conjunction with drawings and Examples, the method for attachment of precast concrete plank of the present invention is described in detail.
A kind of embodiment of the method for attachment of the precast concrete plank that the present invention proposes, as Fig. 1, precast concrete plank 1 side is embedded with abundant anchoring, exposed portion is Semicircular reinforcing bar 2, described semicircular reinforcing bar 2 hangs with transverse reinforcement 3, transverse reinforcement 3 is connected reliably with semicircular reinforcing bar 2, ensures that transverse reinforcement gives full play to intensity.Transverse reinforcement can move, rotate on semicircular reinforcing bar, freely adjusts position, facilitates precast concrete plank to transport, lifts, facilitate transverse reinforcement to locate; Transverse reinforcement is hanging on semicircular reinforcing bar in factory, reduce job site steel project.After precast concrete plank 1 installation in position, by the preset clearance inside lap of transverse reinforcement 3 between precast concrete plank, fix, install template in preset clearance bottom, in preset clearance, precast concrete plank is linked to be entirety by concreting 5.The another kind of embodiment of the precast concrete plank method of attachment that the present invention proposes, as Fig. 2, forms precast concrete superimposed sheet with precast concrete plank 1 top concreting in preset clearance.
Fig. 1 schematic diagram turns over turnback can obtain another embodiment of the present invention, and namely the Semicircular reinforcing bar 2 of precast concrete plank 1 is arranged on the position near precast concrete plank 1 epithelium.This embodiment can be used for the connection that floor bears hogging moment region.
In a kind of embodiment of the method for attachment of the precast concrete plank that the present invention proposes, described transverse reinforcement 3 end upwards bends 90
., as Fig. 1 or Fig. 2 or Fig. 3.Or described transverse reinforcement 3 end upwards bends 135
., or other angles, the anchorage length of transverse reinforcement in rear pouring concrete can be increased, increase the connection integrity between precast concrete plank.In order to improve the connection integrity of precast concrete plank further, in described transverse reinforcement corner, longitudinal reinforcement 6 is set, as Fig. 3.
In the method for attachment of the precast concrete plank that the present invention proposes, there is one or more transverse concave groove 4 precast concrete plank 1 side, connection integrity between pouring concrete and precast concrete after can improving between precast concrete plank, and the overlapping regions part of transverse reinforcement is at transverse concave groove place, reduce preset clearance, reduce template amount.Described transverse reinforcement 3 at transverse concave groove place, as Fig. 4, Fig. 6, or in the projection of described transverse reinforcement 3 between transverse concave groove, as Fig. 5.Fig. 8 is the embodiment schematic diagram that precast concrete plank 1 side does not have transverse concave groove.
In the method for attachment of the precast concrete plank that the present invention proposes, other transverse reinforcements are stretched out in precast concrete plank 1 side, as Fig. 7, can increase the connection integrity between precast concrete plank further.
