Abstract
The invention discloses a method for horizontally connecting precast concrete members. The key of horizontal connection among the precast concrete members is the connection of reinforcing steel bars. In the conventional methods, the welding of the reinforcing steel bars or mechanical connection is adopted, so the conventional methods have the disadvantages of complex connection process, relatively higher cost and difficultly ensured connecting performance, and the wide application of precast concrete structures is seriously influenced. In the method of the invention, the one-to-one corresponding reinforcing steel bars which can be horizontally connected with one another are pre-buried in the side edges of the precast concrete members; the exposed parts of the reinforcing steel bars are hemicyclic, while pre-buried ends are completely anchored in the precast concrete members; annular reinforcing steel bars are arranged on the upper parts of the reinforcing steel bars and are connected with the pre-buried hemicyclic reinforcing steel bars arranged on the two sides of the reinforcing steel bars; certain connection gaps are reserved between the annular reinforcing steel bars and the corresponding hemicyclic reinforcing steel bars; and longitudinal long through reinforcing steel bars are inserted into the connection gaps between the hemicyclic reinforcing steel bars and the corresponding annular reinforcing steel bars. The method is used for horizontally connecting the precast concrete structural members.
Description
Technical field:
The present invention relates to carry out method connected horizontally between a kind of precast unit, be specifically related to a kind of be suitable for method for horizontally connecting and construction housing industrialization, the precast concrete member.
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 invention provides the method for horizontally connecting between 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, strengthen greatly switching performance greatly, improve safety, prolonged application life.
Above-mentioned purpose realizes by following technical scheme:
Method for horizontally connecting precast concrete members, be embedded with in the described precast unit side in the horizontal direction can interconnected reinforcing bar one to one, 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.
Described method for horizontally connecting precast concrete members, described precast unit side has continuous projection, by this continuously projection inlay mutually with like product in the horizontal direction and be connected.
Described method for horizontally connecting precast concrete members, 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.
Beneficial effect of the present invention:
1. the method for horizontally connecting precast concrete members that the present invention realized, do not need a large amount of reinforcing bars to be welded to connect program, only need simple manual vertical reinforcement to insert operation and can finish connection, 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 invention horizontal reinforcement and longitudinal reinforcement keep continuously, and design has continuous projection at the interface, can transmit interface shear stress reliably, can fully ensure the overall performance of connected precast unit after therefore connecting.
3. the present invention 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.
