Background technology
Currently, prefabricated concrete structure is broadly divided into assembled integral and prefabricated assembled two class.Assembled integral
Refer to by precast concrete or component is by reinforcing bar, connector or application prestressing force is connected and poured in place concrete
And form whole structure.Its main feature is that it is needed when assembling prefabricated components using the cast-in-place method in part, to strengthen crucial structure
Part or the globality at position, such as beam-ends or styletable.This method is also referred to as " half dry type " assembling, which can ensure to close
The mechanical characteristic of key component is equal to site concrete, has preferable anti-seismic performance.Shortcoming is there are wet construction, and construction process is opposite
Complexity, duration are longer.And prefabricated assembled refer to by built-in connection or apply in advance should by precast concrete or component
The structure that the modes such as power are assembled, and poured in place concrete is not required, therefore also referred to as " dry type " mounting technology.
For opposite " half dry type " technology, this method site operation is easier, and the duration is also short.But due to only relying on connector or pre-
Stress technique connects, and the anti-seismic performance of key member is poor.For example, when using traditional " dry type " mounting technology, it is prefabricated
Beams of concrete directly by connector or applies installed under prestressing in the both sides of prefabricated post.At this point, gravity laod or geological process
The maximal bending moment of generation is located at connecting portion, and the connecting portion lacks the continuous steel bar stress through node, can not fully support
Anti- unfavorable Moment, easily occurs brittle break, very unfavorable for structure safety.In this context, being badly in need of one kind can
To avoid such failure mode, there are excellent mechanical performances and facilitate " dry type " prefabrication and assembly construction joint form of construction, and pin
Rational connection mode is proposed to its feature.

End set the second perforated steel plate built-in fitting, which passes through friction bolt and styletable ends
Second perforated steel plate built-in fitting connects.Precast beam, the first perforated steel plate built-in fitting of prefabricated column end and the second perforated steel plate are pre-
Embedded part is connected by the way of welding with the reinforcing steel bar in precast beam, prefabricated post.
The first perforated steel plate built-in fitting and the size and pore quantity of the second perforated steel plate built-in fitting are different.It is described
Core space, beam end components, styletable component, the size of precast beam and prefabricated post and arrangement of reinforcement situation calculated and determine according to design,
The size and arrangement of reinforcement situation of middle precast beam are consistent with beam end components, and size and arrangement of reinforcement situation and the styletable component of prefabricated post are protected
It holds consistent.
The beneficial effects of the utility model：
(1) there is better mechanical property.It is described in the utility model whole compared to the prefabricated assembled bean column node of tradition
Beam-ends, styletable and the shaping of joint cores formed by integrally casting of body formula bean column node, the continuously distributed steel bar stress of inside configuration,
The anti-seismic performance of node region is more preferable.The linked system by traditional connecting portion, from test piece end to test specimen, shift by middle part,
Weak link is avoided to be in worst moment of flexure and shearing action region, so as to improve the mechanical property of frame structure.
(2) execute-in-place is quick, facilitates construction.Prefabricated components are connected with built-in fitting using friction bolt, are eliminated at the scene
The wet constructions such as casting concrete, shorten the construction period, and improve efficiency.
