Description
Technical field
The present invention relates to a kind of assembled integral concrete component and construction methods.
Background technique
Assembled monolithic concrete structure have industrialized level it is high, convenient for winter construction, reduce on-site wet operation amount, subtract
Few waste of material reduces dust from construction sites, noise, improves construction quality to reach, improves production efficiency, energy-saving and emission-reduction and protection
The purpose of environment.Reinforcement connection for the globality for guaranteeing structure, vertical prefabricated supporting member (wall, column) is dress
With technology the most key in monolithic concrete structure.
At present both at home and abroad there are mainly two types of the rebar connecting technologies of the vertical prefabricated supporting member of comparative maturity: sleeve grouting
Connection and slurry anchor overlap joint connection.Sleeve grouting connection, which refers in pre-buried metal sleeve in precast concrete, is inserted into reinforcing bar
And cement injection base grouting material and the reinforcing bar connection type realized.Slurry anchor overlap joint connection refers to be used in precast concrete
Insertion needs overlapped reinforcing bar in duct made of special process, and cement injection base grouting material and the bar splicing connection side that realizes
Formula.But both methods complicated construction technique, the density of grouting are not easy to examine, and easily become hidden danger of quality.Patent " it is folded to fill core
The method of construction of conjunction assembled reinforced concrete shear wall structure " (ZL201210399425) provides a kind of spelling of vertical shear wall
Method is connect, i.e., reserves vertically communicated hole in component to realize the perforation connection of upper and lower level vertical member reinforcing bar.But this method
Reinforcing bar connection type is still by the way of sleeve connection.Therefore, it is necessary to develop a kind of connection that Simple And Practical is safe and reliable
Method is very necessary.
Summary of the invention
In order to solve the technical problems existing in the prior art, it is an object of the invention to propose that a kind of new assembled is whole
Body formula concrete component and Vertical bar connection method；Due to there is certain cohesion between reinforcing bar and concrete, reinforcing bar will be undertaken
Power be transmitted in neighbouring concrete by cohesion, and further rely on cohesion and pass to neighbouring reinforcing bar.For reliable power transmission,
There must be enough laps of splice between two reinforcing bars.
The mechanism of connection power transmission is overlapped based on concrete member steel bar, the present invention proposes a kind of assembled integral concrete
Component, including multiple sub- concrete components are equipped in every sub- concrete component and wear muscle duct, wear the exterior domain in muscle duct by setting
Meter requires to be configured with vertical reinforcement, is connected between adjacent sub- concrete component by being inserted in the overlap joint reinforcing bar worn in muscle duct；
It wears in muscle duct in described filled with concrete.
Further, in assembled integral concrete component described above, muscle duct is worn in sub- concrete component
Through its top and bottom；The both ends of the overlap joint reinforcing bar are respectively inserted in two adjacent sub- concrete components, realize phase
The connection of adjacent sub- concrete component.
Further, in assembled integral concrete component described above, the vertical reinforcement is close in duct
Wall position is fixed.
Further, in assembled integral concrete component described above, overlap joint reinforcement location and sub- concrete structure
Vertical reinforcement is adjacent in part, direction straight up, protrude into wear muscle duct inside lap reinforcing bar length need to be greater than specification as defined in take
Spreading degree, and the reserved length for being inserted upwardly into the overlap joint reinforcing bar that a knot concrete component wears muscle duct also needs to be greater than specification rule
The fixed lap of splice.
Further, overlap joint reinforcing bar is consistent with the quantity of vertical reinforcement in sub- concrete component and specification.
The specific construction method of assembled integral concrete component recited above is as follows
The prefabricated multiple sub- concrete components of step 1 are prefabricated in every sub- concrete component and wear muscle duct, the outskirt in duct
Domain configures vertical reinforcement by design requirement；
Step 2 erects sub- concrete component prefabricated in step 1 at assembled scene；And enter to take wearing the trace interpolation of muscle hole
Reinforcing bar is connect, and is fixed temporarily；
Step 3 is poured slightly expanded concrete to wearing in muscle duct；
Step 4 slings upper cross-talk concrete component, puts at the top of sub- concrete component in step 3, the son in step 3
The overlap joint reinforcing bar of concrete component penetrates into the wearing in muscle duct of cross-talk concrete component；Upper section prefabricated components and lower section are prefabricated
Members in alignment；Then slightly expanded concrete is poured to wearing in muscle duct again；
Step 5 repeats step 2,3,4, and whole building vertical member assembly is finished.
Further, the sub- concrete component of step 1 specifically the production method is as follows:
Muscle duct is worn by what the method for pre-buried inner template made pre- system concrete component, sub- concrete component wears muscle hole
The exterior domain in road configures vertical reinforcement by design requirement, for the reliable power transmission of the reinforcing bar connecting with duct inside lap, the vertical steel
Muscle is fixed close to duct inner wall position, for forming the outer edge for wearing muscle duct inner template than the summary of vertical reinforcement inner edge line position
It is small；After the initial set for having poured vertical member concrete, (about 10 hours or so) extract inner template out before final set, are formed
Hollow wears muscle duct；
Since sub- concrete component is prefabricated according to a story height segmentation, vertical reinforcement is on the top of sub- concrete component
It is disconnected with bottom end.
Further, the overlap joint reinforcing bar is consistent with the quantity of vertical reinforcement in sub- concrete component and specification, position
It is adjacent to vertical reinforcement in sub- concrete component, direction straight up, is protruded into and wears the length of muscle duct inside lap reinforcing bar and need to be greater than
The lap of splice as defined in standardizing, and the reserved length for being inserted upwardly into a knot concrete component and wearing the overlap joint reinforcing bar in muscle duct
The lap of splice as defined in standardizing need to be greater than.
Beneficial effects of the present invention are as follows:
This method is compared with the traditional method, when pre- system concrete vertical member (wall, column), according to a story height point
Section is prefabricated, is an entirety by the Vertical bar connection in component.In order to reserve upper and lower layer vertical reinforcement overlap joint connection
Space, by sub- precast concrete vertical member be made it is hollow up and down, vertical reinforcement can be penetrated and coagulation can be poured into
The duct of soil；The joint style of reinforcing bar avoids sleeve grouting and slurry anchor overlap joint, simpler, conveniently.Upper and lower prefabricated components
It is an entirety by the concreting in duct, more securely and reliably.
