Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering and construction, in particular to an adjustable earthquake-resistant structure for civil engineering. Background Art

[0002] To put it simply, earthquake-resistant construction means that in order to achieve earthquake-resistant effects, earthquake-resistant designs are carried out on buildings and earthquake-resistant measures are taken during construction. Earthquake-resistant measures refer to the earthquake-resistant design content other than earthquake action calculations and resistance calculations, including earthquake-resistant structural measures. The safety responsibility of civil construction projects is heavy, which may cause economic losses at the least and endanger life safety at the worst. Therefore, it is very important to do a good job in the safety design of civil engineering projects.

[0003] For example, announcement number CN 212585946 U discloses a seismic test device for civil engineering structures, comprising a base, the top of which is fixedly connected to two first springs. In this seismic test device for civil engineering structures, connecting plates on both sides respectively squeeze and stretch the second springs to achieve the purpose of left and right vibration. By loosening the bolts, the telescopic rod can be lengthened, and the combined length of the telescopic tube and the telescopic rod can be adjusted to change the amplitude of the left and right vibration. The structure is simple and easy to operate. A hydraulic push rod pushes the first plate downward, squeezing the first spring. The hydraulic push rod then retracts, restoring the elastic force of the first spring, thereby driving the first plate to vibrate up and down, achieving the purpose of up and down vibration. The squeezing amplitude of the first spring is adjusted by adjusting the pushing distance of the hydraulic push rod, thereby achieving the purpose of adjusting the up and down vibration amplitude. The structure is simple and easy to operate. This seismic test device has an easy-to-adjust vibration amplitude and a simple structure with low cost.
