Description
Technical field
The present invention relates to connecting elements technical field, overhanging connection between especially a kind of prefabricated component beam column suitable for capital construction
Steel box pin-connected joint built in shelf type precast assembly.
Background technique
With advances in technology with the raising of capital construction technical level, the industrialization increasing prevalence of assembling type buildings, assembled
Concrete structure has become a kind of dominant form of China's housing industrialization in recent years.Traditional prefabricated concrete structure is one
The kind globality structure type poorer than cast-in-place concrete structure, and installation effectiveness, bending stiffness, energy dissipation capacity compare
Weak, quality is unable to get effective guarantee, therefore difficult prevailing.According to well-known at present " for there is the beam column of anti-seismic performance requirement rigid
Property connection should constructively guarantee that the destruction of rigid beam prior to destruction of a node, guarantees bean column node when meeting with rare violent earthquake
Safety, the i.e. design principle of " strong column and weak beam, the weak component of strong node " " as it can be seen that connecting node reasonable structure and reliable operation
Property is particularly significant.At present in the beam-to-column joint of prefabricated component, the steel bar connecting joints of grouting sleeve formula are mostly used greatly, due to beam column
Connecting section is vertical neat section, therefore interconnects and need to set up support frame in lower part when installing, and fills again after node interconnection and fills out coagulation
Soil, just dismountable support frame, general provision are 28 days after concrete hardening, intensity reach design strength requirement, hence it is evident that Yu Cheng
This and duration are unfavorable.Moreover, this connection section is the structure type of vertical neat section and needs to build support frame and just can be carried out
Interconnection constructs and longer need to keep cured tradition Setting pattern again thereafter, and not only method is backward, property easy for construction is poor, work efficiency
It is low, at high cost, and technical effect is also poor, so, consider to owe ideal from practicability and economy point.
Summary of the invention
In the presence of overcoming the shortcomings of the prior art, a kind of structurally reasonable and scientific, peace is provided
Fill steel box pin-connected joint built in shelf type precast assembly convenient and quick, that globality is strong, shock resistance is good after interconnection.
Steel box pin-connected joint built in shelf type precast assembly of the invention, main body include breech face and pre-buried setting in coagulation
Column border node, the breech face that stiffness anchoring in earth pillar is weldingly connected are welded on the included class bracket node on rigid back end face, special
Sign is that the Column border node and class bracket node are filled the post of by the identical built-in steel box stiffness node of a pair of of structure, in which:
The built-in steel box stiffness node body includes steel box, column bracket and docking interconnection plate；
The steel box is formed by welding by steel plate, the L-shaped ladder square block of main body, by being constituted compared with long block and shorter blocks interconnection, by
Compared with the front end face A of long block, the front end face B of shorter blocks and between the front end face A and front end face B, by the side compared with long block
The ladder-like front end face of Z-shaped shelved working face interconnection and constitute steel box filled the post of；
The column bracket include main body pass through be welded on the front/rear end compared with long block, be equipped with front overhanging end A
Longer bracket and main body pass through the relatively short corbel for being welded on the front/rear end of shorter blocks, being equipped with front overhanging end B；
The docking interconnection plate includes the docking interconnection plate being welded on longer bracket front overhanging end A, and be welded on compared with
Docking interconnection plate B on the overhanging end B of short corbel front;
When work, built-in steel box stiffness node is arranged in pairs, and breech face is welded on respectively is embedded in stiffness anchoring in concrete column
On upper and rigid back end face, and it is located below the relatively long block for the built-in steel box stiffness node for being installed in concrete column side, if
The shorter blocks set in the built-in steel box stiffness node of rigid beam side are located below, and it is complementary to be connected to each other duration short block, while being made just
The built-in steel box held in concrete column side is put in working face fitting of shelving on the built-in steel box stiffness node of beam side compared with long block
Shelving on working face compared with long block on stiffness node, thus make the docking interconnection plate A of two pairs of nodes with dock interconnection plate B
It mutually fits, steadily dislocation contact, is convenient to docking without external world's support and tethers, again two after the completion of being bolted
Concrete grout of a node circumfusion for the purpose of the surfacing of junction.
Steel box pin-connected joint built in shelf type precast assembly of the present invention based on above-mentioned design, due to by built-in steel box stiffness
One interface of node is reasonably set to be interconnected that the Z-shaped that constitutes is ladder-like, and docking point is misplaced by interconnection by long short block
Rigidly connected two pairs of nodes are filled the post of, and other than being conducive to enhance connection reliability, ensure construction quality, also advantageously improve and apply
The simplicity of work, during Butt Assembling, as can by built in being arranged in concrete column side on steel box stiffness node compared with
Shelving for long block shelves working face compared with long block on the built-in steel box stiffness node of the rigid beam side of working face holding, does not need the external world
Support can be realized and carry out time saving, laborsaving and convenient and safe interconnection assembly with bolt in the case where stablizing to the state of holding, thus effectively
The trouble that must be provided with special-purpose supporting frame in the prior art is got rid of, while also effectively reducing and reducing the work of high altitude operation
Amount and security risk, but also since the vertical connection section of two pairs of nodes is dislocation arrangement, it can effectively avoid in the prior art
Bending strength brought by single vertical neat section is poor, the drawback of shock resistance difference caused by easy fracture, also reduces concrete and consolidates
The time requirement of change is conducive to improve productivity and reduces construction cost.Therefore technical solution of the present invention and existing skill
Art is compared, hence it is evident that structure is more scientific and reasonable, more convenient and efficient is assembled in interconnection, although increasing a pair of of node, overall cost increases
Add few, and thus bring connection more secure and reliable and time saving, laborsaving, short construction period, to interconnect more reliable and shock resistance strong
Deng very significant technical effect, thus there are technical advance, very strong practicability and valuable market application prospect outstanding.
