Problems solved by technology

[0003] In the seismic test of stainless steel reinforced concrete columns, the vibration motor is often only installed at the bottom, and the power of the motor is used to simulate the earthquake, but the general earthquake is composed of various situations, and the simple longitudinal vibration cannot simulate the earthquake well, and When conducting experiments on stainless steel reinforced concrete columns, the safety of surrounding personnel must also be ensured

Embodiment 1

[0051] Such as Figure 1-Figure 10 As shown, the power mechanism 6 includes a passive sprocket 61, a chain 62, a driving sprocket 63, and a first motor 64. The passive sprocket 61 is connected to the second vibration matching block 36 of the supporting mechanism 3, and one side of the chain 62 is provided with a driving sprocket. 63, the passive sprocket 61 and the driving sprocket 63 are connected by a chain 62, the driving sprocket 63 is keyed to connect the first motor 64, the first motor 64 is connected to the supporting seat 31 of the supporting mechanism 3, and the first motor 64 drives the driving chain Wheel 63, chain 62, passive sprocket 61, make passive sprocket 61 drive the second vibration matching piece 36, the second vibration matching piece 36 cooperates with the first vibration matching piece 35, can make the first vibration matching piece 35 drive the lower end to fix The ring 51 vibrates; the fixing mechanism 1 includes a lower fixing base 11, an upper fixing...

Embodiment 2

[0053] Such as Figure 11 The difference between this embodiment and Embodiment 1 is that the power mechanism 6 includes a worm gear 611, a worm screw 612, and a second motor 613, the worm gear 611 is connected to the second vibration matching block 36 of the support mechanism 3, the input end of the worm gear 611 is connected to the worm screw 612, and the worm screw The input end of 612 is connected to the second motor 613, the fixed end of the second motor 613 is connected to the bearing seat 31 of the support mechanism 3, the second motor 613 is started, and the second motor 613 drives the worm 612 and the worm wheel 611, so that the worm wheel 611 drives the second vibration The matching block 36, the second vibration matching block 36 and the first vibration matching block 35 can make the first vibration matching block 35 drive the lower fixing ring 51 to vibrate.

Abstract

The invention discloses an anti-seismic structure experiment device for a stainless steel reinforced concrete column and a method for using it, including a fixing mechanism, a power mechanism for providing a vibration force, an upper fixing mechanism for a fixing effect, a lower fixing mechanism for providing a stable The inner side of the fixing mechanism is connected to two sets of the supporting mechanisms, the inner side of the upper end of the stretching mechanism is connected to the upper fixing mechanism, and the inner side of the lower end of the stretching mechanism is connected to the support mechanism. The invention has a reasonable structure. The device uses the supporting machine to generate the longitudinal vibration force at the bottom, and at the same time, the stretching mechanism is used to provide the transverse and torsional force, so as to improve the variable amount of the test and the reliability of the test. The upper and lower fixing mechanisms are used. The stainless steel-reinforced concrete column can be quickly clamped, ensuring the reliability of the environment during the test, and avoiding danger when the stainless steel-reinforced concrete column breaks.

Description

technical field [0001] The invention relates to the field of anti-seismic experiments of stainless steel reinforced concrete columns, in particular to an anti-seismic structure experimental device for stainless steel reinforced concrete columns and a use method thereof. Background technique [0002] Stainless Steel Reinforced Concrete Column means that in order to compress the cross section of the concrete column in high-rise buildings, the section steel is placed in the column to enhance the bearing capacity of the column. The commonly used section steel is cross-shaped and square tube-shaped, and the connected basement and foundation are all made of reinforced concrete structure. Reinforced concrete frame structures often need to carry out seismic experiments before actual load-bearing. The seismic performance of reinforced concrete frame structures mainly depends on the seismic performance of frame beams and columns. The beam-column seismic test is a way to test the seism...
