Between friction bond, and coagulation earth cooperation shearing resistance improves the axial compression resistance of steel pipe sleeve and meets the transmission of bucket internal force；Described
The upper and lower ends of steel pipe sleeve side are respectively arranged with multiple sleeve prepared screw-bolt holes, are installed when facilitating construction；The beam-ends
Pre-embedded steel slab is square plate, and its middle part is equipped with square hole, both sides and the sleeve of steel pipe sleeve above and below beam-ends pre-embedded steel slab
Prepared screw-bolt hole corresponding position is provided with steel plate prepared screw-bolt hole, is correspondingly provided with and adds at the left and right sides of each steel plate prepared screw-bolt hole
Strength rib, ribbed stiffener can increase depth of section of the beam-ends at node, and improving beam-ends section rigidity at node makes beam-ends node
Locate plastic hinge, so as to increase the bearing capacity of node and ductility；It is provided in the beam in beam and indulges muscle in stirrup and beam；It is described
Steel pipe sleeve is mounted on column, is provided in column in column and is indulged muscle, and steel pipe sleeve takes the form of welding to be connected with indulging muscle in column；
The beam-ends pre-embedded steel slab welds together with indulging muscle in beam, strengthens the bonding with concrete；Novel joint beam at node
End bar need not go deep into node, simplify node construction, facilitate concrete vibrating；The beam-ends pre-embedded steel slab uses high intensity
Bolt passes through sleeve prepared screw-bolt hole and steel plate prepared screw-bolt hole and steel pipe sleeve connection.
The thickness of the steel pipe sleeve is 20mm.
The cross puts more energy into and is uniformly distributed hole on web, and concrete vibrates when facilitating construction, can be better
The bonding of steel pipe sleeve and concrete is improved, improves the synergistic effect of steel pipe sleeve and concrete, so as to improve node carrying energy
Power.
Existing prefabricated construction bean column node can be divided by its construction method：
（1）Wet type node, i.e. cast-in-place node, during construction, in order to strengthen at node intensity and ensure beam column it
Between load transmission, using at node stirrup encryption and beam-ends, styletable Bar Anchorage or binding the methods of, so that at node
Construction is complicated, and difficulty of construction is big, it is difficult to ensure node quality.
（2）Dry type node is typically referred to weld, is bolted, firm nose suspension type connection etc., although this type of attachment is wetter
Formula is easy to connect and environmentally friendly, but due to construction method is more complicated in work progress and is susceptible to mistake or inconsummate technology
Lead to mistake, it is difficult to ensure that between the intensity of node and beam column load transmission.
Compared with prior art, it is had the beneficial effect that possessed by the utility model：
（1）Certain thickness steel pipe sleeve is replaced to encrypt stirrup at node, operative constraint joint cores concrete,
The cross web of putting more energy into of welding in plate sleeve, and ribbed stiffener is added in weld, improve steel pipe sleeve axial compression resistance and
Meet the transmission of cylinder internal force.
（2）Steel pipe sleeve on column at node is attached with beam-ends pre-embedded steel slab by high-strength bolt or welding form,
Facilitate and construct and can effectively ensure that construction quality.Under violent earthquake effect, using the node structure of high-strength bolt type of attachment
Part such as forms hinge mechanisms damage in beam-ends, need to only replace the precast beam after shake is ruined, realize the recycling of component.
（3）Steel pipe sleeve replaces encryption stirrup, and beam-ends reinforcing bar need not be inserted at node, solved traditional node and asked
Topic-joint structure is complicated, and concrete vibrating is difficult.
（4）Beam column component all can in factory using industrialized production, at node the welding of component can also be completed in processing factory,
Construction welding job is reduced, quality is easily controllable, greatly speeds up the fast progress of construction.
（5）Beam-ends pre-embedded steel slab is indulged muscle with beam and is welded together, and strengthens the bonding with concrete.
