Description

A kind of novel fabricated bean column node of imitative joggle
Technical field
The utility model is related to a kind of novel fabricated bean column nodes of imitative joggle, belong to prefabricated assembled field.
Background technology
Prefabrication refers to being built made of assemble in site with prefabricated component.This building, which has, builds speed Degree is fast, and climate conditionality is small, saves labour, reduces energy resource and occupies and consume and construction quality and performance can be improved The characteristics of, there is vast potential for future development.
There have been some representative prefabrication projects and demonstration project in China at present, is ground in structural system Achieve some achievements and progress on studying carefully, but in practical application there is also some critical issues have it is to be solved.
The connecting node of prefabricated assembled concrete component is that the connection type of weak link and component determines that structure is whole The stability of body.Domestic existing the relevant technologies regulation pours monoblock type connection method, such connecting node area master after being all made of at present Muscle and construction stiffener all connect, and prefabricated components are linked as entirety by node area using rear pouring concrete and grouting material, from And the structural elements is made to be linked to be mutually unified entirety, ensure the globality of structure, weak part is effectively treated.Assembled integral In structure, the bar connecting of node and seam crossing preferably uses mechanical connection, sleeve grouting connection and is welded to connect, between can also be used Connect overlap joint.
Thin doctor, which is accounted for, more than later stage nineteen sixty (DR.ALFRED A.YEE) has invented straight screw sleeve connection device, Splice Sleeve receives the prefabricated post steel bar joining (Honolulu, Hawaii) in hotel in 38 buildings my moirs for the first time, has started column continued access Rigid joint;Japanese TTK companies are modified to shorter Tops Sleeve.The principle of reinforced bar sleeve grouting connection is through casting Hollow type sleeve, reinforcing bar penetrates sleeve inner from both ends open, need not overlap or fuse, filled between reinforcing bar and sleeve high-strength The structural mortar of microdilatancy is spent, that is, completes steel bar joining action.
Presently, there are problems with for the connection of prefabricated assembled component:
1. carry out bar connecting using reinforced bar sleeve grouting connection type at present, neither one is unified, specification and specific Construction method can follow, when practice of construction be inevitably present constructing operation it is more random, it is lack of standardization, cumbersome, apply The problems such as work work is relatively low, quality of connection is poor easily causes the waste of time and cost and consequence that node quality is difficult to ensure.
2. although reinforced bar sleeve grouting interconnection technique has well solved longitudinal steel in prefabricated assembled concrete structure Muscle connectivity problem can effectively realize the equivalent cast-in-place design requirement of assembly.But the most internal structure of sleeve of current generally use Complexity, manufacturing process is cumbersome, and cost is higher, and high to the accuracy of alignment requirement that need to connect reinforcing bar, and there are bar connecting processes Complicated, the defects of hand labor intensity is big, connection speed is slow.
3. overlapped, marching method cannot be used for the linking of big standard reinforcing bar, add shortcoming there are many welding, (such as steel raw material is stable, the poor situation of solderability;Power supply is not stable or the horizontal poor situation of welder;Duration is tight, capacitance Not all right situation;And the ice-cold equal climatic effects of wind and rain;The also construction plan in the high place of fire prevention demand;Horizontal reinforcement shows The quality and speed of field linking.) welding quality is unable to ensure.
Joggle as the common skill of China's traditional architecture and ancients' crystallization of wisdom, be it is a kind of by tenon be inserted into mortise or The juncture of tongue-and-groove, concrete operations are:In two block of material, one piece is made tenon, and another piece is made mortise or tongue-and-groove, and two pieces are worn To together, two block of material are fixed together by friction or occlusion by material.The utility model is summarizing prefabricated assembled company On the basis of the Problems Existing connect, the juncture of joggle is used for reference, it is proposed that a kind of novel joint.
Utility model content
The purpose of this utility model is to provide a kind of reliable in quality, assembly overlap joint is convenient, the good imitative tenon of anti-seismic performance Connect assembled bean column node.
The utility model is used for reference the wooden skill joggle method of tradition and is combined with being bolted, by analysis node loading characteristic, Energy consumption process and overlap joint mechanism propose a kind of new approaches of novel joint, i.e. beam column overlap joint is main by the way of imitative joggle, Node is made of the prefabricated tongue-and-groove of styletable and the prefabricated tenon of beam-ends:On the one hand, the pre-embedded steel slab in column, and pass through dowel and column Inner concrete anchor connection, three face steel plate of outside weld, wherein both sides steel plate are L-shaped, and the prefabricated tenon in a U-shaped section is integrally formed Slot presets duct on tongue-and-groove bottom plate and places rubber sheet gasket;On the other hand, prefabricated tenon by concrete, peripheral Baogang and Elongated bolt composition.When assembled in situ, directly prefabricated tenon is placed on prefabricated tongue-and-groove, is engaged and is provided by the high intensity of the two The bearing capacity of node, while fixed bottom nut, and welding angle steel is used as fixed and dissipative cell above beam column overlap joint.
What the utility model node was brought has the beneficial effect that:
1. the utility model node joint imitates joggle and bolted mode, by tenon and tongue-and-groove it is high-strength be engaged with And the shear behavior of bolt provides the bearing capacity of node, greatly strengthens the strength and stability of node, meets that " strong node is weak The design requirement and feature of component ".
It is finished 2. all components required by the utility model node are all prefabricated in the factory, realizes " industrialization " production; Tenon need to be only placed on to tongue-and-groove, fixed bottom nut when in-site installation, and weld angle steel, it is whole based on " dry operation ", Installation is in place convenient and time-saving, overcomes the defect of traditional construction technique.
3. the utility model substitutes traditional sleeve grouting technique, more " economy " using the assembly method for imitating joggle.
4. the utility model node places rubber sheet gasket at the steel plate of prefabricated tongue-and-groove bottom surface, can fill prefabricated error causes Uneven gap, also can energy-dissipating and shock-absorbing, and mitigate the friction between contact steel plate and collsion damage, and then improve node Anti-seismic performance enhances the stability of node, and node is made to have certain runback bit function.
5. the utility model node welds angle steel above beam column overlap joint, angle steel not only serves as the dissipative member of earthquake, And the beam column relative displacement that the imitative dovetail manner may be brought can be limited as the retaining element of beam column, in certain journey The Self-resetting of node is realized on degree, while also enhancing the load-carrying properties of node.
