Abstract

The invention relates to a prefabricated concrete structure interlayer seismic isolation method. The method comprises the following steps: step 1, forming an upper connecting hole in an upper concretecolumn, and forming a lower connecting hole in a lower concrete column to prepare a rubber seismic isolation column; step 2, inserting the lower end of the rubber seismic isolation column into the lower connecting hole; step 3, fixing the upper concrete column above the lower concrete column in a liftable manner; step 4, inserting the upper end of the rubber seismic isolation column into the upper connecting hole; step 5, overlapping lower fixing claws on a lower hole portion inner flange and overlapping upper fixing claws on an upper hole portion inner flange; step 6, pouring concrete in theupper connecting hole and pouring concrete in the lower connecting hole; and step 7, dismantling a support structure after the concrete in the upper connecting hole and the concrete in the lower connecting hole are solidified. By adopting the prefabricated concrete structure interlayer seismic isolation method provided by the invention, the problem of a poor seismic isolation effect between layers of the existing prefabricated concrete structure is solved.

Description

Technical field [0001] The invention relates to the field of construction engineering, in particular to a method for isolating an assembled concrete structure layer. Background technique [0002] As the most important system of industrialized buildings, prefabricated concrete structures have the advantages of high quality, short construction period, low energy consumption and green construction. Therefore, it has broad research and development space and important social value for fabricated concrete structures. [0003] However, the existing fabricated structure layers are connected by concrete pouring together. This method has poor side displacement resistance at the connection and is prone to cracking and cause the connection to fail. In order to overcome the above problems, it is changed to The connecting seat is supported between the layers, and the connecting seat is connected with the upper and lower layers by bolts. Although this connection method overcomes the poor anti-si...
