Embodiment 1

[0027] Embodiment 1: This embodiment aims to provide an intelligent test device for cyclic loading of shear parts. In view of the shortcomings of the existing structure, it is impossible to truly simulate the actual force condition of the shear parts. This embodiment can not only easily realize one-way loading Shear testing, but also cyclic loading smart shear testing can be easily implemented as required.

[0028] like figure 1 As shown, an intelligent test device for cyclic loading of shear parts includes a vertical fixed plate, an actuator, a fixture and a test platform; the vertical fixed plate is vertically fixed on the shear wall, and the vertical fixed plate The middle part is vertically provided with double track 1 arranged at intervals, and the bottom of the actuator 2 is provided with a track groove corresponding to the double track 1, and the track is in a dovetail structure, so that the bottom of the actuator 2 is nested on the track. The double dovetail-shaped ra...

Embodiment 2

[0032] Embodiment 2: This embodiment is basically the same as Embodiment 1, the difference is that this embodiment further limits the structure of the clamp.

[0033] Fixture 7 comprises two halves 71 and connecting bolts 72, the butt joint surfaces of two halves 71 have corresponding notches 73, the four corners of two halves 71 are provided with corresponding through holes, and the connecting bolts are set in the through holes so that the two halves The half pieces are connected together, the side wall of the notch is provided with fine teeth, the clamp 7 is clamped on the shearing part, and the fixing fixture can make the shearing part firmly fixed, and the radian of the notch 73 is smaller than π at the same time. Different clamps can be used for shear parts of different specifications. During the clamping process, the fine teeth include tooth blocks connected together. The tooth blocks are basically in the shape of an isosceles triangle. Shaped parts, and the shear parts ...

Embodiment 3

[0034] Embodiment 3: This embodiment is basically the same as Embodiment 1, the difference is that this embodiment further limits the installation method of the load sensor.

[0035] Both sides of the load sensor 6 are provided with screw rods, and the thread directions of the screw rods on both sides are opposite. The middle part of the clamp 7 and the middle part of the telescopic rod 4 are provided with corresponding screw holes. The screw rods are synchronously connected on the telescopic rod 4 and the clamp 7.

[0036] Simultaneously in this embodiment, because screw hole is respectively arranged in the middle part of telescopic rod 4 and clamp 7, thereby when completing connection, screw hole and screw rod have certain rigidity, thereby makes the middle part of clamp and telescopic rod 4 correspond to the middle part, and The middle part of the fixture is provided with a notch correspondingly, and the middle part of the shear member can be made to correspond to the middl...

Abstract

The invention belongs to the technical field of building structure test equipment, and particularly relates to an intelligent cyclic loading test device for a shear-resistant part, which has the maincontribution that the shear-resistant performance of the shear-resistant part can be tested, a one-way loading shear-resistant test can be easily realized, and an intelligent cyclic loading shear-resistant test can be easily realized as required. The vertical position of the actuator is adjustable, so that different height positions of the shear-resistant part can be tested, the test device is suitable for shear-resistant parts with different lengths, the application range and the detection range of the test device are improved, the shear-resistant part is mounted on the test platform throughthe transverse moving seat, and the shear-resistant part can be aligned to the test device; what is ensured is that the acting force applied by the actuator to the shear-resistant part is consistent with the force detected by the load sensor, the authenticity of detection data is improved, the structure is reasonable, detection is accurate, the actual stress condition of the shear-resistant part can be truly simulated, and the device is a great innovation of shear-resistant part detection.

Description

technical field [0001] The invention belongs to the technical field of building structure test equipment, and in particular relates to an intelligent test device for cyclic loading of shear parts. Background technique [0002] There are many problems in the construction process of traditional construction buildings: long construction period, dust pollution, large labor demand, defective components, etc., which can no longer meet the development requirements of my country's construction industrialization. [0003] The development of prefabricated buildings complies with this requirement. Fast construction, low pollution, less labor required, industrialized production, and standardized construction make prefabricated buildings a favorite. The connection between different components in prefabricated structures has always been a difficult problem that scholars have been working hard to solve. Commonly used methods include sleeve type, cantilever short beam type, truss beam, uni...
