Embodiment Construction

[0025] Displacement meter fixing device in civil engineering structure experiment, please refer to Figure 1 to Figure 4 , including a main body bracket 1 and an adjusting part 2, the main body bracket 1 is made of aluminum alloy.

[0026] The main body bracket 1 includes a main rod 11, a solid seat 12 and a U-shaped seat. The main rod 11 is arranged vertically. Seats 12 are respectively arranged on the front and rear sides of the main rod 11, and the opening of the U-shaped seat is arranged forward. The U-shaped seat includes a middle rod 13 and end rods 14 respectively fixed on both sides of the middle rod 13 , and the lower end of the main rod 11 is fixed at the middle position of the top surface of the middle rod 13 . A first threaded hole 15 is concavely formed on the rear end surface of the solid base 12 , and a second threaded hole 16 is formed on one end rod 14 .

[0027] The adjustment member 2 is a butterfly bolt, and the butterfly bolt includes a screw rod 21 , wh...

Abstract

The invention discloses a fixing device for a displacement meter for civil engineering structure experiments and a method of using the fixing device. The fixing device comprises a main support and anadjuster; the main support includes a main rod, a fixing seat and a U-shaped seat; the tail end face of the fixing seat is provided with a first threaded hole in concave manner; the first threaded hole can be connected with a stud that is fixedly connected to a test object; the U-shaped seat and the adjuster can cooperate to clamp the displacement meter; therefore, the fixing device can help tightly connect the test object, the fixing device and the displacement meter, loosening of the displacement meter during an experiment can be effectively avoided, and measurement errors due to unexpectedloosening of the displacement meter are prevented. The fixing and the test object can be bolt-connected through the stud welded to the test object and the first threaded hole of the main support; thestud can be placed at any part of the test object so that resting of the displacement meter is facilitated; measuring points are more flexible to set during an experiment.

Description

technical field [0001] The invention relates to the field of building structure experiments, in particular to a displacement meter fixing device and a using method in civil engineering structure experiments. Background technique [0002] Civil engineering structure experiment is an important means to research and develop new components, new materials and new systems of engineering structures, and plays an important role in the scientific research of engineering structures. In order to measure the deformation of the experimental object, the commonly used measurement method is to arrange a displacement meter on the experimental object, and use the displacement meter to measure the deformation of the experimental object. The conventional displacement meter fixing device is a magnetic meter base with a chuck, which can be adsorbed on the iron part of the loading device, and the displacement meter is fixed by the chuck and arranged at a position parallel or perpendicular to the e...
