Abstract
The utility model relates to a precast concrete unit. The key of the horizontal connection among precast concrete units is the connection of steel reinforcements. The traditional method adopts steel reinforcement welding or mechanical connection but has complicated connection processes, higher cost and difficult guarantee of the connection performance, thus the wide application of the precast concrete structure is seriously affected. The utility model provides a precast concrete unit (1), wherein steel reinforcements (2) which are butted in the horizontal direction are pre-buried in the side edge of the precast concrete unit, the exposed part of each steel reinforcement is in a semi-ring shape, and the other end of each steel reinforcement is pre-buried in the precast concrete unit and is fully anchored. The utility model is applied to the horizontal connection among precast concrete units.
Description
Technical field:
The utility model relates to and carries out member connected horizontally between a kind of precast unit.
Background technology:
Key connected horizontally between the precast unit is the connection of reinforcing bar, and conventional method is by reinforcing bar welding or mechanical connection, but linker complexity, cost are higher, and switching performance is difficult for guaranteeing.To have a strong impact on the extensive use of precast concrete like this.
Summary of the invention:
The utility model provides a kind of precast unit, make and no longer need complicated program and plant equipment when carrying out level between the precast unit connects, make link cost reduce greatly, strengthened switching performance greatly, improved safety, prolonged application life.
Above-mentioned purpose realizes by following technical scheme:
Precast unit, reinforced concrete member, be embedded with the reinforcing bar of horizontal direction butt joint in the described precast unit side, the part that described reinforcing bar exposes is a semicircular, and the other end of described reinforcing bar is embedded in fully anchoring in the precast unit.
Described precast unit, described precast unit side have in the horizontal direction inlays the continuous projection that is connected mutually with like product.
The beneficial effects of the utility model:
1. the precast unit realized of the utility model carries out in the building construction process, do not need a large amount of reinforcing bars to be welded to connect program, only need again link position to add the rectangle reinforced steel bar ring, and between the semi-circular reinforcing bar of reinforced steel bar ring and this patent, vertically reinforcing bar is inserted, can finish the connection of both sides precast unit, characteristics are built in the construction that is suitable for the housing industrialization precast concrete of energy-conserving and environment-protective.
2. junction of the present utility model horizontal reinforcement and longitudinal reinforcement keep continuously, and the design of the junction of concrete component has continuous projection, can transmit interface shear stress reliably, can fully ensure the overall performance of connected precast unit after therefore connecting.
3. the utility model has changed the whole floor casting craft of existing highrise building fully, construction technology is simple, can build place beyond on-the-spot finish prefabricated units health and maintenance, greatly improved speed of application, member can carry out single-piece and detect, construction quality is easy to guarantee, work progress does not need complicated mechanical equipment and facility, does not need power consumption yet.The building course environmental protection and energy saving, reduce cost, save construction fund.Be traditional do not have interconnective floor or monobloc cast along with the building height slowly health upwards build important breakthrough on the mode.
Description of drawings:
Accompanying drawing 1 is the connecting axle mapping.
The specific embodiment:
Embodiment 1:
Precast unit, be embedded with in described precast unit 1 side in the horizontal direction can interconnected reinforcing bar one to one 2, the part that described reinforcing bar exposes is a semicircular, its pre-buried end is fully anchoring in precast unit, the ring-type reinforcing bar is placed on described reinforcing bar top, join mutually with the pre-buried semicircular reinforcing bar of both sides, be reserved with certain handing-over space therebetween, insert vertical elongated reinforcing bar in the handing-over space between described semicircular reinforcing bar and the ring-type reinforcing bar.
Embodiment 2:
Embodiment 1 described precast unit, described precast unit 1 side can also have continuous protruding 3, by this continuously projection 3 inlay mutually with like product in the horizontal direction and be connected.
During use, both sides install and the interconnective template of like product before and after the described precast unit, behind described template upper pouring concrete, through maintenance, two precast units are connected into integral body.
Claims (2)
1. precast unit, reinforced concrete member, it is characterized in that: be embedded with the reinforcing bar of horizontal direction butt joint in the described precast unit side, the part that described reinforcing bar exposes is a semicircular, and the other end of described reinforcing bar is embedded in fully anchoring in the precast unit.
2. precast unit according to claim 1 is characterized in that: described precast unit side has in the horizontal direction inlays the continuous projection that is connected mutually with like product.
