Description
Technical field
This patent belongs to building field more particularly to a kind of high-rise assembly concrete shear wall structure boxlike connection structure
And method.
Background technique
Prefabricated assembled concrete structure has that few energy consumption, system easy to control the quality, speed of application be fast, construction site environment
The advantages that good and concrete shrinkage crack is few.Prefabricated assembled concrete structure may advantageously facilitate China building industrialization and
Housing industrialization, exploitation are suitable for the prefabricated assembled shear wall structure residential housing of industrialization, and undoubtedly future architecture develops
Direction.China's high residential building is based on reinforced concrete structure at present, and there are three types of basic structure forms: shear wall knot
Structure, frame-shear-wall structure and frame structure.Frame and frame-shear-wall structure are used in residential housing due to being influenced by column
It obtains seldom, shear wall structure is the most common structure type of high residential building, and high-rise prefabricated assembled shear wall structure is suitable
Close the residential industrialized building system of China's national situation.
For assembly concrete shear wall structure, the connectivity problem between prefabricated components is that its research and extension is answered
The reliability pair of (i.e. horizontal joint connection) is connected between one of key technical problem in, especially upper and lower level precast shear wall
Assembly of shear wall structure overall performance is most important.
Connection for fabricated shear wall vertical reinforcement, current Chinese code of practice " prefabricated concrete structure technical regulation "
(JGJ1-2014) it is mainly recommended to use sleeve grouting connection and slurry anchor overlap joint connection (Fig. 1), but in view of shear wall is vertically distributed
The quantity of reinforcing bar is more, diameter is small, if every vertical distribution bar all uses sleeve grouting connection or slurry anchor overlap joint connection, due to
More demanding to construction precision, component inevitably will lead to reserved steel bar positional shift during production, maintenance, transport and make
Wallboard lifting is difficult, to will increase cost and difficulty of construction.
Summary of the invention
To solve the above problems, the invention discloses a kind of bolted-on attachments of full prefabricated concrete structure bean column node
Structure and method.The present invention is to replace the vertical distribution bar of precast concrete shear wall with bar reinforcement, in embedded bar end
The end of embedded bar is carried out thread processing by reserving installation hole slot on precast shear wall, and connection box is protruded into wall in assembly
In the reserved installation hole slot of body, then it is connected by screw bolts.It is this compared with sleeve is in the milk connection and slurry anchor overlap joint interconnection technique
Boxlike interconnection technique avoids the corresponding grouting hole for respectively reserving every reinforcing bar insertion, will make site operation more in this way
Add convenient and efficient.And interface shearing-resistance is carried out using the connection box across seam, structure is more safe and reliable.
To achieve the above object, the technical solution of the present invention is as follows:
A kind of high level assembly concrete shear wall structure boxlike connection structure, including precast shear wall, precast shear wall
Interior pass through has embedded bar, and the installation hole slot for exposing embedded bar end is formed on precast shear wall, exposes installation hole slot
The end of embedded bar is formed with external screw thread, and embedded bar is connected with connection box by external screw thread；It connects box and is in installation hole slot
It is interior；Connection box top and bottom surface shape are formed with the through-hole with embedded bar cooperation, and embedded bar is connected with across through hole whorl
Nut, the connection box lateral surface parallel with precast shear wall, which is open, to be arranged；Adjacent precast shear wall passes through connection box, pre-buried steel
Muscle and nut are interconnected and fixed.
Further to improve, the through-hole extends to the connection box medial surface parallel with precast shear wall and forms L shape.
Further to improve, the external screw thread passes through the processing forming of lathe thread.
Further to improve, the contact surface of adjacent precast shear wall starches adhesion by seat.
A kind of bolt connection of full prefabricated concrete structure bean column node, includes the following steps:
Step 1: embedded bar both ends working process is formed into external screw thread, it is pre-buried in precast shear wall；
Step 2: the reserving installation hole slot on the precast shear wall of the embedded bar end；
Step 3: will connect box by after precast shear wall lifting in place and be put into the mounting hole reserved on precast shear wall
In slot, and box will be connected by nut and linked together with embedded bar；
Step 4: being sealed by filling microdilatancy mortar into connection box, the installation of precast shear wall component is completed,
Precast shear wall component interconnected is set to form an entirety.
Further to improve, the connection box top and bottom surface shape are formed with the through-hole with embedded bar cooperation.
Further to improve, the through-hole extends to the connection box medial surface parallel with precast shear wall and forms L shape.
The invention has the advantages that
On the one hand distribution bar is replaced with bar reinforcement and is connected by screw bolts, the q&r of raising reinforcing bar connection,
Accelerate speed of application, on the other hand, high-rise type connections across seam place, enhance precast shear wall horizontal connection at intensity and
Rigidity significantly improves the stress performance of structure.

Specific embodiment
The present invention will be further described with reference to the accompanying drawings and embodiments.
Embodiment
The vertical distribution bar connection method of high-rise assembly concrete shear wall structure as illustrated in figs. 2 through 8, it is mainly logical
It crosses high-rise type connections to be attached upper and lower level precast shear wall, type connections are mainly (i.e. pre- by connection box and dowel
Bury reinforcing bar) composition, main Connection Step are as follows:
Step 1: will replace vertical distribution bar bar reinforcement (i.e. embedded bar) both ends carry out thread processing, it is pre-buried extremely
In precast shear wall；
Step 2: the reserving installation hole slot on the precast shear wall component of the embedded bar end；
Step 3: will connect box after the prefabricated part hanging is in place and be put into the installation hole slot reserved on wall,
And box will be connected by bolt and linked together with dowel；
