The device is that the design concept of adopting the locking device for a pre-fabricated hanging plate maintaining structure is proposed; a locking device manufactured from brittle material is designed; a prefabricated hanging plate and a lower main structural cross beam are fixed, so as to ensure the normal use function of the enclosing structure; the connection between the locking device and the main structure can be kept in a complete state in case of frequent earthquake, and thus the purpose of continuously using the whole structure under medium- and low-level earthquake; in case of strong earthquake, the foam concrete in the surrounding is disconnected, the brittle locking device is broken, the hanging plate type enclosing structure is suspended on a beam body through a connecting device and swings about a hanging beam under the earthquake effect, so as to change the earthquake cycle of the structure as well as reducing the energy entering the structure due to the earthquake, and as a result, the purpose of reducing the response of the main structure to the earthquake can be achieved, and the earthquake-proofing performance of the whole structure is improved.
Description
Technical field
The present invention relates to a kind of locking device of frame structure building plate-hanging type damping space enclosing structure, be applicable to frame structure building, can under common earthquake, prefabricated concrete board be made to be fixed in lower beam, can rupture under severe earthquake action, by connection hanging piece, prefabricated concrete board is swung around drop in beam, produce damping power consumption effect, reach reduction seismic structural response, improve the object of structural entity anti-seismic performance.
Background technology
Frame construction is common architecture structure form, and along with further developing of CHINESE INDUSTRIES house, assembled-type house will adopt tower structure in a large number.Conventional frame structural construction, when earthquake occurs, is built formula or seat-plate type retaining wall by laying bricks or stones or moves with agent structure, not only increasing dead load, totally unfavorable to agent structure antidetonation; And under severe earthquake action, build formula or seat-plate type enclosed structure by laying bricks or stones easily cave in and hurt sb.'s feelings.How when almost additionally not increasing construction cost, by rationally arranging the structure locking device between enclosed structure and agent structure, reduce the seismic demand of agent structure, increase the overall anti-seismic performance of building, be the problem needing to solve, this point is particularly important to assembling industrialization house.Therefore, this patent proposes a kind of locking device, under common earthquake effect, can allow prefabricated concrete board is the same with existing build-in type wall interior panel to be stablized locked in sub-body structure, not affect normal use; And disconnect under severe earthquake action, prefabricated concrete board is swung around agent structure beam under geological process, produces damping power consumption effect, reach the object reducing seismic structural response, improve structural entity anti-seismic performance.
Summary of the invention
The anti-seismic performance that formula or seat-plate type enclosed structure not only do not utilize space enclosing structure is very well built by laying bricks or stones for tradition, but also become this phenomenon of the burden of agent structure under geological process, the present invention proposes the design philosophy adopting prefabricated link plate enclosed structure locking device, the present invention is adopted by the fragile material locking device that design is special and prefabricated concrete board and sub-body structural beams is fixed, to ensure the normal usage function of space enclosing structure.Under common earthquake effect, the connection between locking device and agent structure remains intact, and can continue with structural entity under shake effect lower in reaching the object used.Under severe earthquake action, filleting connects disconnection, fragility locking device ruptures, plate-hanging type space enclosing structure hangs on Liang Tishang by linkage, swing around drop in beam under geological process, thus change structure earthquake period, consume the energy of Seismic input structure, reach the object reducing agent structure seismic response, improve the anti-seismic performance of structural entity.
The present invention adopts following technical scheme:
A locking device for industrialization house plate-hanging type damping space enclosing structure is a kind of pin adopting glass.The power F first born under severe earthquake action according to locking device 1, severe earthquake action is in structure, produce acceleration a, the quality m of precast plate, every block prefabricated concrete board 2 is fixed on the body construction by connector and 2 locking devices 1, the ultimate shear stress of locking device 1 is φ, so the computing nodes of locking device 1 amasss A=0.25ma/ φ.
In work progress, agent structure of first constructing, and bore 2 holes at agent structure lower transverse beam 3 end face, anchor adhesive after putting in hole, inserting locking device 1, holes at correspondence position in prefabricated concrete board 2 lower end, is inserted by prefabricated concrete board in locking device 1 fixing.
According to the design scheme of this patent, require that, under common earthquake effect, the seismic forces that locking device 1 bears is less than its ultimate shear stress, does not rupture, prefabricated concrete board 2 is connected complete with agent structure, the object that can normally use with structure after reaching medium and small shake.Under rarely occurred earthquake effect, the seismic forces that locking device 1 bears is greater than ultimate shear stress, brittle fracture occurs, and prefabricated concrete board 2 and lower beam 3 disconnect, and agent structure surrounding foam concrete 6 disconnects, prefabricated concrete board 2 and agent structure upper beam 4 are formed hinged by linkage 5, swing around upper beam 4 under geological process, and then the natural vibration period of extending structure, consume Seismic input to the energy of agent structure, thus reduce the seismic response of agent structure, reach the object of damping.It is a kind of locking device of frame construction plate-hanging type damping space enclosing structure.
Frequently occurred earthquake, common earthquake and rarely occurred earthquake, generally by basic earthquake intensity zoning or ground motion parameter zoning, the regulation of locality is adopted, be respectively the earthquake of 50 Annual exceeding probabilities 63%, 10% and 2% ~ 3%, or the recurrence interval is respectively the earthquake of 50 years, 475 years and 1600 ~ 2400.
Good effect of the present invention is: the proposition of this patent can under the condition that cost is substantially identical, can make prefabricated concrete board normal with keep being connected complete under geological process with agent structure, can not swing, the practicality of raising structural entity.Also can rupture under rarely occurred earthquake effect simultaneously, make prefabricated concrete board by linkage around crossbeam swing, improve the anti-seismic performance of structural entity, thus reduce the seismic response of agent structure.
