Description
Technical field
The present invention relates to building structure technology fields, and in particular to a kind of steel concrete supporting dress using sleeve connection
It sets.
Background technique
As assembled architecture policy constantly pushes and the raising of market acceptance, assembled architecture development such as fire at present
Such as the bitter edible plant, each enterprise in each department all falls over each other to develop assembled architecture.In the assembled architecture using shear wall structure, mainly with pre-
Concrete shear force wall processed is in the majority.
For precast concrete shear wall, the vertical interconnection technique of shear wall is had been a concern, current main steel
The problem of muscle connection type is grout sleeve connection, but inventor has found in practice of construction due to component precision and scene are applied
The influence of worker person and condition cause grout sleeve connection that cannot smoothly connect comprehensively, occur being vertically connected with difficulty, there are larger
Construction and security risk；The increase of cost is also resulted in using grout sleeve connection simultaneously.And the reinforcing bar set of this shear wall
Cartridge type hidden-type engineering, construction quality cannot ensure that there are larger security risks for construction, and situ wet operation is excessive.Steel
Muscle mechanical connection can very good solution the above there are the problem of, but existing threaded coupling sleeve, tube-in-tube structure
Complexity needs threaded reinforcing bar cooperation assembling, there is a problem of that component complexity overall cost is high.Existing extruding links sleeve,
Geometry and the problem of discontinuity after extruding, there are certain quality risks.
Summary of the invention
Dangerous when inconvenience when based on the connection of the above grout sleeve is connected with grout sleeve, the present invention provides one kind
It processes and easy for construction, using the steel concrete supporting node of sleeve connection.The steel concrete supporting node of this kind of sleeve connection
Using the convenient advantage of steel structure connection, both solved the problems, such as that grout sleeve connection site operation was difficult, and also solved grouting
Sleeve connection, which can not detect, uses unsafe problem caused by compaction rate, form of sleeve is simple, connects the quality of posterior nodal point
Controllably.
To achieve the goals above, the present invention adopts the following technical scheme:
The first telescopic steel concrete supporting device provided by the invention, the steel concrete supporting section of the sleeve connection
Point, including flat sleeve, the first pin, the first reinforcing bar and the second reinforcing bar；First reinforcing bar is inserted into from the first end of flat sleeve,
It is stretched out from the second end of flat sleeve；Second reinforcing bar is inserted into from the second end of flat sleeve, is stretched out from the first end of flat sleeve；First steel
The axis of the axis of muscle, the axis of the second reinforcing bar and flat sleeve is parallel to each other, and between the first reinforcing bar, the second reinforcing bar between formation
Gap；First pin is inserted into from one end of flat sleeve, in the gap that the first reinforcing bar and the second reinforcing bar are formed.
Further, the telescopic steel concrete supporting device further includes the second pin, the first pin, the second pin
The insertion opposite from the both ends of flat sleeve respectively, in the gap that the first reinforcing bar and the second reinforcing bar are formed, the first pin, second
Pin axis is on same straight line.As further technical solution, it is equipped in the flat sleeve and the first reinforcing bar, the
The mutually matched screw thread of two reinforcing bars.
As further technical solution, the pin forms the tip for having plane in end by processing, so as to pin
Nail squeezes into fixation, and prevents pin from springing back.
Second of telescopic steel concrete supporting device provided by the invention, the steel concrete supporting section of the sleeve connection
Point, including flat sleeve, pin, the first reinforcing bar and the second reinforcing bar；On the flat sleeve be equipped with hole, the axis of hole with it is flat
Sleeve axis is vertical；First reinforcing bar is inserted into from the first end of flat sleeve, is stretched out from the second end of flat sleeve；Second reinforcing bar
It is inserted into from the second end of flat sleeve, is stretched out from the first end of flat sleeve；The axis of first reinforcing bar, the axis of the second reinforcing bar and flat
The axis of sleeve is parallel to each other, and forms gap between the first reinforcing bar, the second reinforcing bar；Pin is inserted into from hole, is located at the first steel
In the gap that muscle and the second reinforcing bar are formed.
As further technical solution, it is equipped in the flat sleeve and cooperates with the first reinforcing bar, the second reinforcing bar
Screw thread.
As further technical solution, the pin forms the tip for having plane in end by processing, so as to pin
Nail squeezes into fixation, and prevents pin from springing back.
When the steel concrete supporting node in-site installation using sleeve connection, first by bar splicing in sleeve,
Pin is squeezed into completion from sleeve both ends to fix, then installation template, pours and be vertically connected with place's concrete.
The beneficial effects of the present invention are:
