Abstract
The utility model discloses a spherical node of assembled concrete frame with from reset function, beam -ends design into the spheroidicity and are embedded into in the post, reserve the prestressing tendons pore in the middle of the precast beam unit, implement stretch -draw to prestressing tendons during the site assembly. Connect the construction and give first place to with " dry operation ", carry out the grout of non - designability around the node, consider at junction embedding rubber pad that the damage that can lighten the member upon impact can guarantee also that absorption cell surrenders the rotation deformability of back node. The utility model discloses the structure has from the reset function, through the mode that designs into the beam -ends spheroidicity, makes the anti -seismic performance of beam column node effectively improve, simultaneously easy to assemble taking one's place.
Description
Technical field
The utility model relates to a kind of assembly concrete framework sphere nodes with Self-resetting function.
Background technology
Prefabrication is the building structure of suitability for industrialized production, and features such as having from heavy and light, construction is fast, construction noise is little, cost is low, energy-saving and environmental protection, technique are simple, has vast potential for future development.Prefabrication is studied, has important practical significance and using value.Propose a kind of prefabricated assembled frame structure system at present, adopted a kind of novel light monolithic architecture wallboard collecting the function integrations such as precast construction, insulation, decoration, waterproof, fire prevention, achieve structure-function integration.Applied for the patent of wall self-insulation technology, city, the great Xi river Gongjian's project in Yixing, Jiangsu Tai Yuan Environmental Protection Technology Co., Ltd newly construct the factory buildings, garden, Yixing Mountain-spring north etc. has carried out demonstration project construction.But China not yet forms theory and technology system that is unified, specification to its technical system.Therefore, needing to carry out systematized theoretical research to the key position-node of prefabricated costruction, providing fundamental basis for promoting industrialization of construction industry.
For accelerating development prefabricated, the mounting technology of construction project, improve industrialization of construction industry Integration ofTechnology level.Support the industrialization construction of base of Integration Design, production, construction overall process, pilot is carried out in the city that alternative condition possesses, and accelerates marketing application.Country and provinces and cities all propose construction object, and the assembled architecture area as China's construction in 2015 reaches 1,000 ten thousand square meters, and single building requires that prefabrication and assembly construction rate reaches 30%.60% is reached to the year two thousand twenty single building prefabrication and assembly construction rate.Country, for the project adopting prefabrication, awards and tax revenue aspect preferential policy, and preferential wall of returning changes the support such as fund, cement in bulk fund.In assembly concrete frame construction, node is the key position connecting beam column, directly affects the performance of framework entirety.At present, the main Problems existing of prefabricated costruction has:
The standardized designs of assembling coagulation scholar structure and modularization make problem.This is the inevitable requirement of suitability for industrialized production, and relate to simultaneously connected mode between component, leakproof and the structure of thermal insulation, corresponding connection fittings series of problems is set etc.
The link technique of prefabricated concrete structure prefabricated units.Under the prerequisite ensureing overall structure safety, globality, simplify connecting structure as far as possible.Reduce the uncertain impact on structural performance in construction.Meanwhile, the leakproof of junction, antiseepage and insulation problem etc. should be paid close attention to.
The establishment of the design of assembling coagulation scholar setted structure, making, construction and acceptance criteria.Conscientiously should grasp on the basis of prefabricated concrete structure performance, determine the requirement of supporting method for designing, manufacture craft, construction guidbook and acceptance criteria etc.Ripe and the popularization with facilitated technique.Although a lot of building enterprise has all put into effect respective provincial standard.But because regional center (RC) is sex-limited and the inadequate system of standard and maturation, hinder each technology in nationwide popularization and application.
Utility model content
The utility model object is that the defect existed for prior art provides a kind of assembly concrete framework sphere nodes with Self-resetting function.
The utility model uses for reference the structure of domestic and international ductility joint, the loading characteristic of analysis node and Energy Dissipation Mechanism, proposes a kind of novel joint structure thinking: beam-ends is designed to elliposoidal and embeds in post; In the middle of precast beam unit, reserved presstressed reinforcing steel duct, implements stretch-draw to presstressed reinforcing steel during site assembly.
The beneficial effects of the utility model: the utility model is simple and practical, by beam-ends bulbous configuration, make beam, post component, under geological process, Rigid Body in Rotation With ability occurs, component itself is from damage, and globe joint can alleviate the local compression in beam column rotation process.
Accompanying drawing explanation
Fig. 1 node drawing of the present utility model;
In Fig. 1,1-presstressed reinforcing steel, 2-rubber pad, 3-screed.
Detailed description of the invention
Shown in Fig. 1, be a kind of assembly concrete framework sphere nodes with Self-resetting function, beam-ends is designed to elliposoidal and embeds in post; In the middle of precast beam unit, reserved presstressed reinforcing steel duct, implements stretch-draw to presstressed reinforcing steel during site assembly.
The foregoing is only preferred embodiments of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
1. have an assembly concrete framework sphere nodes for Self-resetting function, it is characterized in that, beam-ends is designed to elliposoidal and is embedded in post; In the middle of precast beam unit, reserved presstressed reinforcing steel duct, implements stretch-draw to presstressed reinforcing steel during site assembly; Connection construction, based on " dry operation ", carries out unstructuredness grouting around node, considers to embed rubber cushion blocks in junction, can alleviate damage during member impacts, also can ensure the Rigid Body in Rotation With ability of the dissipative cell surrender back rest.
2. a kind of assembly concrete framework sphere nodes with Self-resetting function as claimed in claim 1; it is characterized in that, the end of beam is designed to elliposoidal, improve the Rigid Body in Rotation With ability of beam; alleviate local compression stress, protect component in earthquake from damage.
