Safety and the anti-seismic performance of fabricated construction can be greatly improved with formula structure, is the development that China's future architecture industrialization is built
Direction.
The present assembled levels in China are restricted by design of node, and due to domestic first stage of construction, labour is opposite
Inexpensively, construction technology is largely by artificial, and the developed countries such as external particularly American-European and Japan, assembled technology more into
Ripe, construction technology relies primarily on machinery.The building level in China mostly rests on cast-in-place, it is impossible to fully achieve equally cast-in-place.And
Building site is cast-in-place by resource restrictions such as time, manpowers, and speed of application is slow.It if can be completely using splicing and overlapping technology, institute
There is accessory by prefabrication, transport to building-site, by splicing and overlap, connected completely using dry type, wet type is avoided to connect,
Outdoor work is replaced with office operation, construction efficiency can be greatly improved.The design of novel fabricated building node is building work
The key problem and apt word added to clinch the point of industry.There are a series of researchs, scholar Lv Xilin etc. to show to add in steel to this domestic and foreign scholars
Even can more effectively improve the performance of node than adding in vinal concrete after fiber concrete, improve reinforcing bar with
The adhesion strength of concrete improves ductility.2013, scholar Sun Yanbo devised a kind of connector to connect precast concrete beam
Column border node makes it improve anti-seismic performance, i.e., shifts to an earlier date the ductility connecting rod of pre-buried alloy in pre- buried column, and alloy link passes through itself
Plastic deformation carry out earthquake energy, so as to avoid the destruction of other components.Wang Qingjie etc. proposes a kind of novel steel tube coagulation
The anti-seismic performance of earth pillar and section steel beam assembling type node, and low all reciprocation cycle loading examinations have been carried out to the node of different parameters
It tests.
But apparently, main problem and limitation are for just current research, especially domestic research：First, largely set
Meter cannot completely disengage cast-in-place, using dry-and-wet combined formula, still remain the situation of site welding, it is impossible to accomplish efficient quick；The
Two, design of node is too complicated, and accessory is cumbersome, changes and is not easy.

Shape；The connecting pin of precast beam is variable cross-section end, and variable cross-section end is connected by pre-buried serration type shear key with the bracket of prefabricated post,
And the first half embedment precast beam of shear key, the lower half embedment prefabricated column bracket of shear key.
Preferably, prefabricated post is connected with the outside on the junction both sides of precast beam by steel plate, using bolt from being located at
Precast beam or the steel plate of prefabricated post side pass through precast beam or prefabricated post, also cross the gap of pre-buried serration type shear key
Place, is pierced by from the steel plate for the opposite side for being located at precast beam or prefabricated post and is fixed with nut.
Preferably, prefabricated post and precast beam use concreting of the intensity for C80, indulge muscle and use Q345 with stirrup
Steel, it is prefabricated in assembled plant, it transports to live directly assembled.
Preferably, the bracket upper surface of prefabricated post and the variable cross-section end upper surface of precast beam are according to the sawtooth
The size of formula shear key has stayed pre-buried position.
Preferably, serration type shear key is prefabricated in the factory according to die size, direct splicing is embedded in pre- at the scene
Between column bracket and precast beam processed.
Preferably, bolt uses 8.8 grade high-strength bolts.
Preferably, the junction vertical plane part of prefabricated post and precast beam adds rubber sheet gasket.
The beneficial effects of the utility model are：
Structure design is simple, convenient for assembling, is connected firmly, easy to spread.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the sectional view along A-A of Fig. 1.
Fig. 3 is the serration type shear key structure diagram of the utility model embodiment.
It is marked in figure：1- prefabricated posts, 2- precast beams, 3- serration type shear keies, 4- steel plates, 5- bolts, 6- rubber sheet gaskets.
Specific embodiment
Fig. 1 is a kind of connection structure of prefabricated concrete structure beam column, is resisted by prefabricated post 1, precast beam 2, serration type
Key 3, steel plate 4, bolt 5, rubber sheet gasket 6 is cut to form.
The connecting pin of precast beam 1 is a step-like variable cross-section end, and the variable cross-section end of precast beam passes through serration type shear key 4
It is attached thereto at the bracket of prefabricated post 2, forms connecting node.
For the bonding strength of enhancing connecting portion, two blocks of steel plates 5 have also been correspondingly arranged in the both sides of precast beam and prefabricated post,
Steel plate is in each point of sub- bracket part of beam and column half.4 intensity is used to connect the steel plate of both sides for 8.8 grades of high-strength bolt
Fixed, bolt passes through steel plate, above two bolts wear beam and mistake, below two sub- brackets of bolt prick post and mistake, also cross saw
The gap up and down (Fig. 2) for lying down king's word shape of tooth-like shear key.
Bolt and steel plate play fixed function.Position to prevent sawtooth shear key or bolt is overlapped with reinforcement location, institute
Quantify to fix with the position of component and accessory, to ensure that bolt will not get to the detailing requiments such as reinforcing bar.
To buffer integrated member stress in the horizontal direction, flexible rubber has been installed additional at the gap that prefabricated post is connect with precast beam
Glue material, i.e. precast beam and the vertical plane of prefabricated post contact portion are partially placed into rubber sheet gasket 3, make building by level side
To power effect when with certain cushioning effect.

Serration type shear key is to be embedded between prefabricated column bracket and precast beam in advance.When pre-buried, by serration type shearing resistance
The top half of key is submerged in the precast beam on top, and the lower half portion of serration type shear key is submerged in the prefabricated column bracket of lower part,
Each half, realization splice and resist horizontal force up and down in this way.
It, be according to the size of serration type shear key when being prefabricated in the factory at the side section end of prefabricated column bracket and precast beam
Pre-buried position is stayed in advance, when assembling can efficiently be constructed with quick-assembling.
The primary effect of serration type shear key is resistant to shear, and limit levels direction is subjected to displacement, while also is able to increase
The snap-in force of connecting portion.
Prefabricated post and precast beam use concreting of the intensity for C80, indulge muscle with stirrup using Q345 steel, exist
Assembled plant is prefabricated, transports to live directly assembled.Wherein C80 concrete make prefabricated components under use environment have compared with
Good durability, safety other than with high intensity, are also provided with many new technical indicators.
The present embodiment use assembled technique, scene avoid it is cast-in-place, save the duration, articulated connection mode is with ensure that node
Free Transform under the lower effect of shake effect, so as to improve integrally-built anti-seismic performance.
Above-described the utility model embodiment, does not form the restriction to scope of protection of the utility model.It is any
Modifications, equivalent substitutions and improvements made within spirit of the present utility model and principle etc., should be included in the utility model
