Description

Technical Field

[0001] The utility model relates to the technical field of earthquake resistance testing, in particular to a frame earthquake resistance testing platform for construction engineering design. Background Art

[0002] The frame structure has the advantages of flexible space division, light weight, and short construction period. It is widely used in multi-story buildings. After the frame is produced, the frame model needs to be seismically tested to test the frame's seismic resistance.

[0003] After searching, Chinese patent CN220854091 U was retrieved and announced a frame seismic inspection equipment for construction engineering design. The staff rotates the threaded sleeve to make the threaded rod shrink in the middle of the threaded sleeve to adjust the overall length of the threaded rod and the threaded sleeve, to adjust the distance between the slide rods, and to make the side of the slide rod fit tightly against the side of the frame. At this time, the staff rotates the rotating shaft to set the pressure rod in a vertical state, and by rotating the bolt, the top of the bolt is set on the surface of the slide rod to position several pressure rods. At this time, the output end of the hydraulic cylinder is retracted to move the positioning plate downward. At this time, several pressure rods can be moved downward, so that several pressure rods are tightly fitted against the upper surface of the frame. The surface plays a role in positioning the frame. The process of installing and disassembling the frame by this device is simple and stable. The first electric guide block moves in the middle of the first electric guide rail, and the second electric guide block moves in the middle of the second electric guide rail. At the same time, the support platform is shaken back and forth, and the frame is driven to shake, and the frame is subjected to an earthquake test. It can be seen that this patent realizes the fixation of frames of different specifications and the front and back and left and right shaking of the frame. Then, earthquake waves have not only transverse waves but also longitudinal waves. The above patent realizes the transverse wave earthquake test, but does not have the longitudinal wave earthquake test. For this reason, a frame earthquake test platform for construction engineering design is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a frame seismic test platform for construction engineering design, which has the advantage of being convenient for seismic testing of longitudinal earthquake waves.

[0005] In order to achieve the above-mentioned purpose of facilitating seismic longitudinal wave seismic resistance testing, the present invention provides the following technical solutions: a frame seismic resistance testing platform for construction engineering design, comprising a base plate, a mounting shell fixedly mounted on the top of the base plate, and a wave assembly for performing seismic longitudinal wave seismic resistance testing provided on the mounting shell;

[0006] The wave assembly includes a fixed shaft, a movable shaft, a motor, an eccentric wheel and a wave rod, wherein the fixed shaft is fixedly mounted between opposite sides of the inner side wall of the mounting shell, the movable shaft is rotatably connected between opposite sides of the inner side wall of the mounting shell, the motor is fixedly mounted on the outer surface of the mounting shell, the output shaft of the motor is fixedly mounted on the movable shaft, the eccentric wheel is fixedly mounted on the outer surface of the movable shaft, the eccentric wheel is fixed at various positions on the outer surface of the movable shaft, the wave rod is rotatably connected to the outer surface of the fixed shaft, and the wave rod is mounted on the outer surface of the eccentric wheel.

[0007] Furthermore, the movable shaft is located outside the fixed shaft, the eccentric wheel is cylindrical in shape, and the front and rear end surfaces of the eccentric wheel and the wave rod are flush.

[0008] Furthermore, a through hole is provided on the substrate and located on the outer side of the mounting shell.

[0009] Furthermore, a connecting block fixedly connected to the wave rod is rotatably connected to the outer surface of the fixed shaft, and there is a gap between each eccentric wheel and each wave rod.

[0010] Furthermore, a mounting groove is provided on the upper surface of the wave rod.

[0011] Compared with the existing technology, the utility model provides a frame seismic test bench for construction engineering design, which has the following beneficial effects:

[0012] The frame seismic test bench designed for this construction project is equipped with a wave component. After the wave component is used, the movable shaft drives the eccentric wheels in different directions to rotate, so that the wave rod is driven by the eccentric wheel to swing back and forth along the axis of the fixed shaft. Due to the eccentric wheels in different directions, the ups and downs of the wave rod are different, forming wave crests and troughs, thereby forming a shape similar to the longitudinal wave of an earthquake, thereby realizing the longitudinal wave seismic test of the frame.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-3 A frame seismic test bench for construction engineering design includes a base plate 1, a mounting shell 2 is fixedly installed on the top of the base plate 1, a through hole 4 is opened on the base plate 1 and located on the outside of the mounting shell 2, the base plate 1 can be fixed by passing a screw through the through hole 4, and the base plate 1 can be disassembled by removing the screw.

[0019] See also Figure 1-3 A wave assembly 3 for performing earthquake longitudinal wave seismic resistance testing is provided on the mounting shell 2. The wave assembly 3 includes a fixed shaft 31, a movable shaft 32, a motor 33, an eccentric wheel 34 and a wave rod 35. The fixed shaft 31 is fixedly mounted between opposite sides of the inner wall of the mounting shell 2, and the movable shaft 32 is rotatably connected between opposite sides of the inner wall of the mounting shell 2. The movable shaft 32 is located on the outside of the fixed shaft 31, and the motor 33 is fixedly mounted on the outer surface of the mounting shell 2. The output shaft of the motor 33 is fixedly mounted on the movable shaft 32. When the motor 33 is started, the movable shaft 32 rotates, and the longitudinal wave seismic resistance testing work is gradually performed.

[0020] In addition, the eccentric wheel 34 is fixedly mounted on the outer surface of the movable shaft 32 and can rotate along with the movable shaft 32. The eccentric wheel 34 is cylindrical in shape and is fixed at various positions on the outer surface of the movable shaft 32. The distance between the axis of the eccentric wheel 34 and the axis of the movable shaft 32 determines the amplitude. The larger the distance, the larger the amplitude, and the smaller the distance, the smaller the amplitude. The wave rod 35 is rotatably connected to the outer surface of the fixed shaft 31 and can rotate along the axis of the fixed shaft 31.

[0021] At the same time, the wave rod 35 is mounted on the outer surface of the eccentric wheel 34. Since the eccentric wheel 34 is located at various positions on the outer surface of the movable shaft 32, the mounted wave rod 35 is driven to move up and down, thereby forming a shape similar to the longitudinal wave of an earthquake, thereby realizing the longitudinal wave seismic test of the frame. The outer surface of the fixed shaft 31 is rotatably connected to a connecting block 5 fixedly connected to the wave rod 35. There is a gap between each eccentric wheel 34 and each wave rod 35. The front and rear end faces of the eccentric wheel 34 and the wave rod 35 are flush, and the upper surface of the wave rod 35 is provided with a mounting groove 6.

[0022] When this embodiment is in use, the frame is built on the wave rod 35, the motor 33 is started, the movable shaft 32 and the eccentric wheel 34 rotate, and the eccentric wheels 34 in different directions drive the wave rod 35 to swing around the axis of the fixed shaft 31, so that the multiple wave rods 35 gradually form a seismic longitudinal wave pattern that fluctuates back and forth, thereby performing seismic longitudinal wave resistance test on the frame.

[0023] The beneficial effects of the above embodiment are:

[0024] The frame seismic test bench for the construction engineering design is provided with a wave component 3. The rear movable shaft 32 of the wave component 3 drives the eccentric wheels 34 in different directions to rotate, so that the wave rod 35 is driven by the eccentric wheel 34 to swing back and forth along the axis of the fixed shaft 31. Due to the eccentric wheels 34 in different directions, the ups and downs of the wave rod 35 swing differently, forming wave crests and troughs, thereby forming a shape similar to the longitudinal wave of an earthquake, thereby realizing the longitudinal wave seismic test of the frame.

[0025] The motor 33 mentioned in the text is electrically connected to a main controller and a power supply. The main controller can be a conventional known device for controlling a computer, etc., and the existing disclosed power connection technology is not described in detail in the text.
