Abstract
The invention provides a masonry structure-based isolated structure, which comprises a building blocks layer and an isolated layer in vertical alternating arrangement, wherein the building block layer comprises an upper reinforcement mortar layer, building blocks, and a lower reinforcement mortar layer; and the isolated layer is located between the adjacent two building block layers. The whole isolated structure is arranged between a foundation top surface and the superstructure, thus, the structure can bear most of deformation of the whole building under the action of earthquake so as to ensure safety and reliability of the superstructure. The building block layer only generates horizontal rigid motion at the time of suffering the earthquake; and the isolated layer arranged between a foundation top surface and the superstructure generates horizontal shearing deformation, which restrains the horizontal motion of the building block layer, thereby having isolating function and limit effect. The invention has the advantages of reasonable structure, simple construction and lower cost of construction, can effectively improve shock absorption and disaster prevention capacity of brickworking houses, obviously improves the isolated capacity of the brickworking houses based on the non-change traditional construction method and particularly is applied by being matched with brickworking buildings.
Description
Technical field
The invention discloses a kind of isolation structure, be meant a kind of isolation structure especially based on the masonry building; Belong to the building structure technology field.
Background technology
The big several times earthquake of China's generation in recent years all occurs in rural area or small towns, and mostly these regional houses are the masonry building, in earthquake, have suffered a large amount of destruction.The anti-side rigidity of masonry building is bigger usually, and its basic cycle T is generally less than place Tg eigenperiod.So the seismic load that this house is born in earthquake is often very big, and is as shown in Figure 2.Because the intensity of masonry structure is generally lower, if do not increase necessary construction measure, structural deterioration is inevitable.If increase the cost that these measures will inevitably increase the house.Though there has been the measure of many shock insulations in China, these measures otherwise just too expensive, otherwise be exactly that complex structure, technical requirements are high.Based on this situation, research and develop a kind of rational in infrastructure, construction is simple, cheap, can effectively improve rural area local-style dwelling houses, the urban housing damping performance of taking precautions against natural calamities, and it is very necessary not change the seismic isolation technology of conventional construction method.
Summary of the invention
The objective of the invention is on the basis of the deficiency that overcomes prior art, to provide a kind of rational in infrastructure, construction is simple, cheap, can effectively improve the take precautions against natural calamities isolation structure of ability of masonry building damping.Guarantee that when earthquake takes place isolation structure effectively reduces the effect of earthquake to masonry building, promptly the masonry structure on top does not excessively destroy, caves in because of being out of shape.The property and the life security of protection masonry building interior.
A kind of isolation structure based on the masonry building of the present invention is made up of in vertical arranged alternate building block layer and shock insulation layer, and said building block layer comprises that arrangement of reinforcement screed, building block reach arrangement of reinforcement screed down, are provided with the shock insulation layer between adjacent two building block layer.
Among the present invention, saidly go up the arrangement of reinforcement screed, be furnished with the horizontal mesh reinforcement sheet in the arrangement of reinforcement screed down, said reinforced mesh is formed by reinforcing bar binding in length and breadth, thereby, can guarantee the strength and stiffness of building block layer.
Among the present invention, said shock insulation layer is guaranteeing to have preferably to have horizontal shear deformability preferably in the vertical bearing capacity, and its upper and lower surfaces is provided with lines to guarantee well boning with screed.
Among the present invention, mortar used in the said building block layer is a composite mortar, has higher intensity and adhesive property.
Among the present invention, said shock insulation layer is by the rubber manufacturing.
Working mechanism of the present invention is sketched in following:
The present invention is owing to adopt said structure; Lateral rigidity through the reduction of the rubber layer in isolation structure masonry house prolongs the single order natural vibration period of total system, and the single order that masonry is built surpasses the eigenperiod in place natural vibration period; Thereby the horizontal earthquake influence coefficient that makes the masonry building is in the descending branch of earthquake effect coefficient curve; Referring to accompanying drawing 2, reduce the earthquake response of masonry house, and make distortion mainly concentrate within the isolation structure; Reduce the distortion of superstructure, thereby superstructure is protected.
At the multi-layer building block layer of isolation structure set inside, guaranteed an isolation structure occurred level motion under the geological process effectively, thereby increased the ability of the overturning or slip resistance analysis in whole house.The present invention guarantees that through in the individual layer building block layer arrangement of reinforcement screed being set up and down building block layer has enough rigidity and intensity.In addition; Reinforcing bar in the arrangement of reinforcement screed disposes according to the mode of reinforced mesh; Reinforced mesh is formed by reinforcing bar binding in length and breadth; Improve the ability that isolation structure carries vertical load, retrained the generation of the rubber in shock insulation layer horizontal distortion under vertical uniform load q, and then improved the ability that isolation structure carries vertical pressure.
Rubber upper and lower surfaces in the isolation structure has lines, effectively improves the rubber and the bonding reliability of arrangement of reinforcement screed up and down.
The thickness of isolation structure of the present invention and mechanical performance index are confirmed according to the size of top masonry built-loading, and the height of isolation structure is according to height, the number of plies and the load level decision of top masonry building.
Isolation structure of the present invention can be arranged on the apron piece of strip foundation or pile foundation.
When isolation structure of the present invention is constructed, require in principle to accomplish continuously; If interrupt in the middle of needing really, must interrupt at the end face of shock insulation layer.When replying construction, at first clean the end face of shock insulation layer, clean up the arrangement of reinforcement screed above the continued construction.
In sum, the present invention is rational in infrastructure, construction is simple, cheap, and the shock insulation ability of masonry building is obviously improved, and special the adaptation with masonry built supporting use.This technology can effectively improve the ability of taking precautions against natural calamities of masonry building,
