Description

  The present invention relates to a vibration exciter and a vibration test method for a house for testing and measuring the earthquake resistance of an existing house by generating a pseudo shake of an earthquake.

  As a device that generates pseudo-quake of an earthquake, a flat frame-shaped foundation frame is fixed to the floor of the test site building, and a horizontal excitation frame can be freely moved in a predetermined horizontal direction via a linear bearing on the foundation frame. The vibration floor is supported on a horizontal vibration frame via a spring leg, and a rolling cylinder for reciprocating the vibration floor in the horizontal direction is interposed between the horizontal vibration frame and the base frame. While fixing a frame that forms a substantially horizontal support surface on the floor and placing two vibration floors on the support surface movably in a predetermined horizontal direction via linear guides, Two actuators that reciprocate each excitation floor in the guide direction are arranged coaxially on both sides of a common cradle with their operating directions opposite to each other. A common cradle and cradle Such bound vibrating apparatus is disclosed (e.g., see Patent Document 1.).

However, these conventional vibration devices are complicated and bulky, and it is assumed that a new house to be tested is built on the vibration floor and then the house is vibrated. Alternatively, it is assumed that a light-weight and simple structure house is assembled in a building in which a vibration exciter is installed and then placed on a vibration floor with a crane to give vibration to the house. Therefore, in order to test the seismic resistance of existing, post-construction houses using these conventional vibration generators, the houses are dismantled once and carried into the building where the vibration exciter is installed. Such a method is unsuitable because there is a problem that it must be reconstructed on the floor, which takes a lot of time, and changes in the building structure due to reconstruction cannot be avoided and accurate data cannot be obtained.

FIG. 2B shows the configuration of the base 8. The base 8 may be a pair of parallel or multiple pairs of rails on which the rolling tool 6 is placed. In the present specification, the disc-shaped frame means a frame that is framed mainly in a two-dimensional spreading direction, for example, in the shape of a frame, a shoji frame, or a wooden pallet for a forklift. .

  FIG. 3 is an enlarged view of a main part of the vibration means 10, and FIGS. 3 (a) and 3 (b) are a front view and a plan view, respectively. The vibration means 10 includes a hydraulic cylinder 12, a reciprocating piston 14 set in the cylinder 12, a shaft attaching portion 96 at the tip of the piston 14, and a drive of the tip attaching portion 96 and the upper frame 4. A drive plate is interposed between the frame member 20 and fixed to the frame member 20, and is configured by a bearing plate 26 that pivotally attaches a bearing portion 96 to the upper frame body 4 via a pin 24. Due to the reciprocating motion of the piston 14, the upper frame 4 vibrates horizontally (in the direction of arrow B), and thereby the house 1 is vibrated.

  FIG. 4 is an enlarged view of a main part of the rolling tool 6, and FIG. 4 (a) and FIG. 4 (b) are a front view and a side view, respectively. The rolling tool 6 includes an upper plate 34, a pair of bearing side plates 36, 36 depending from both side edges of the upper plate 34, and a pair of bearing side plates 36, via a shaft 38 passed over the bearing side plates 36, 36.
