Pre-embedded bolt hole site is accurately positioned in column 1, and forms the contact surface connecting with fashioned iron connection board 4.
The steel rest 6 of the beam column dry type ductility connection, is the steel branch of angle steel (or thick steel plate and other fashioned iron) form
Support 6 is welded on pre-buried steel liner plate 7, is supported on 4 lower section of fashioned iron connection board, is born end when supporting and work when playing installation
The effect of shearing.
The fire prevention filler 13 of the beam column dry type ductility connection is wrapped in type after beam-to-column joint is installed
Steel weakens 5 surrounding of section, so that structure overall appearance is kept regular, and effective protection steel construction part, improves the connection of beam column dry type
Fire protecting performance.
Two, as illustrated in figs. 8-12: the intercolumniation dry type connection, intercolumniation link position are arranged at inflection point, so that even
The plane of weakness connect improves integrality performance of the structure, while bolt connecting mode realizes column far from the node area of beam-to-column joint
Between the detachability that connects.
The intercolumniation dry type connection, comprising: upper precast concrete column 1U and lower precast concrete column 1D, upper high grade coagulation
Native reinforcement block 14U and lower high-grade concrete reinforcement block 14D, upper styletable steel plate 15U and lower styletable steel plate 15D, upper prop anchor steel
Muscle 16U and lower prop anchor bar 16D, connects bolt 3 and fire prevention filler 13 forms.
The styletable steel plate up and down of the intercolumniation dry type connection, the outer periphery positioned at upper and lower styletable steel plate (15U and 15D) are pre-
12 position of bolt hole is stayed, for connecting the fastening of bolt 3；Upper lower prop anchor bar (16U and 16D) is then fixed using welding method
In upper and lower styletable steel plate (15U and 15D), the lateral surface of upper styletable steel plate 15U and accordingly lower styletable steel plate 15D are by connecting bolt
3 fastenings, by about two precast concrete columns, (1U is connected with 1D)；Medial surface relies on upper lower prop anchor bar (16U and 16D)
Cohesive force and upper and lower high-grade concrete reinforcement block (14U and 14D) even it is integral.
The connection bolt 3 of the intercolumniation dry type connection, is arranged in upper and lower high-grade concrete reinforcement block (14U and 14D)
Around, make to form rigid connection between concrete prefabricated shell of column up and down, it is ensured that effective transmitting of column internal force connects the quantity of bolt 3
It should be determined according to internal force calculating；When specific installation, bolt 3 will be connected across the reserved spiral shell of upper and lower styletable steel plate (15U and 15D)
Keyhole 12 is fastened with nut by certain pretightning force.
The strength mark of the reinforcement block of high-grade concrete up and down (14U and 14D) of the intercolumniation dry type connection is higher than up and down
The strength mark of precast concrete column (1U and 1D), to increase local concrete bearing capacity, compensation intercolumniation junction is due to mixed
The adverse effect coagulating soil reduced cross-sectional and generating；One end of upper and lower high-grade concrete reinforcement block (14U and 14D) is corresponding and upper and lower
(15U's styletable steel plate is connected with 15D), and it is viscous between concrete surface to improve that other end concrete surface requires coarse processing
Power is tied, and above and below locally embedding in precast concrete column (1U and 1D), forms embedded (19)；In order to further enhance intercolumniation connection
Shearing resistance and anti-pressure ability at reduced cross-sectional can wrap up in high-grade concrete reinforcement block exposed parts and paste high strength fibre cloth
(18) lateral deformation is constrained to improving its resistance to compression and shear-carrying capacity.
The upper lower prop anchor bar (16U and 16D) of the intercolumniation dry type connection is to transmit precast concrete column (1U up and down
And 1D) in upper lower prop the supreme lower styletable steel plate (15U and 15D) of internal force suffered by longitudinal reinforcement (17U and 17D) important component,
Column anchor bar is fixed on styletable steel plate by one end by welding；The other end then passes through high-grade concrete reinforcement block up and down
(14U and 14D), anchoring into precast concrete column (1U and 1D) interior certain length, anchorage length up and down should be determined by calculation,
Anchor force can be improved using other effective ways；Upper lower prop anchor bar (16U and 16D) has not only acted as will be prefabricated mixed up and down
Solidifying earth pillar (1U and 1D), upper and lower high-grade concrete reinforcement block (14U and 14D) and upper and lower styletable steel plate (15U and 15D) are connected as
The important channel of internal force transmitting in the effect and intercolumniation connection of one entirety.
The fire prevention filler 13 of the intercolumniation connection is wrapped in high grade up and down after the connection of column column is installed
Concrete reinforcement block (14U and 14D) surrounding not only makes the appearance in intercolumniation connection section keep regular, but also effective protection steel knot
The fire protecting performance of intercolumniation connection is improved in structure part.
The above content is in conjunction with specific embodiments to detailed description made by the utility model, and it cannot be said that this is practical new
Type specific implementation is only limitted to these explanations.For those skilled in the art of the present invention, this is not being departed from
Under the premise of utility model is conceived, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to the utility model guarantor
