[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a glass curtain wall bearing capacity detection device includes two fixed beams 1 arranged up and down, and the fixed beam 1 is fixedly connected to the support surface through a fixing member. There is a movable beam 2 between the two fixed beams 1. The fixed beam 1 and the movable beam 2 fix the specimen 3. Driving mechanisms are arranged on the X-axis, Y-axis, and Z-axis of the movable beam 2. The driving mechanism on the X-axis is connected to the first support mechanism, the driving mechanism on the Y-axis is connected to the second support mechanism, and the driving mechanism on the Z-axis is connected to the third support mechanism;

[0033] The three driving mechanisms on the X-axis, Y-axis, and Z-axis are used to drive the movable beam 2 to move along the X-axis, Y-axis, and Z-axis respectively;

[0034] The first support mechanism, the second support mechanism, and the third support mechanism respectively support the three driving mechanisms to realize the stable operation of the three driving mechanisms.

[0035] In this embodiment: The fixed beam 1, the movable beam 2, and the specimen 3 (i.e., the curtain wall to be tested) are connected by fixed angle codes. The two fixed beams 1 are respectively connected to the upper and lower ends of the specimen 3, and the movable beam 2 is fixedly connected to the middle section of the specimen 3. When detecting the bearing capacity of the specimen 3, by respectively starting the driving mechanisms on the X-axis, Y-axis, and Z-axis, the driving mechanisms drive the movable beam 2 to perform actions on the X-axis, Y-axis, and Z-axis, which can drive the specimen 3 to perform actions on the X-axis, Y-axis, and Z-axis, and then force the specimen 3 to deform under the load, and further measure the bearing capacity of the specimen 3 (also known as: interlayer deformation performance);

[0036] The specific calculation of displacement angle is as follows: The inter-story displacement angle γx in the X-axis dimension is calculated according to the following formula: γx=δx / H, where: H is the floor height, in millimeters (mm), δx is the absolute value of the horizontal displacement in the X-axis dimension, in millimeters (mm);

[0037] The inter-story displacement angle γy in the Y-axis dimension is calculated as follows: γy=δy / H, where: H is the floor height, in millimeters (mm); δy is the absolute value of the horizontal displacement in the Y-axis dimension, in millimeters (mm).

[0038] The height change between layers in the Z-axis dimension is expressed by the absolute value of the vertical displacement δ in the Z-axis direction, and the unit is millimeter (mm).

[0039] Please refer to Figure 1 , Figure 2 and Figure 3 The driving mechanism includes: a driving motor 4, a synchronous wheel 5, a synchronous belt 6, a threaded rod 7, a motor bracket 11 and a mounting plate 18;

[0040] The three groups of threaded rods 7 are respectively threadedly connected to the movable beam 2 along the X-axis, the Y-axis, and the Z-axis, and the three groups of threaded rods 7 are staggered and do not interfere with each other;

[0041] The three mounting plates 18 are rotatably mounted on the outer walls of one end of the three groups of threaded rods 7, and the three groups of synchronous wheels 5 are fixedly connected to the ends of the three groups of threaded rods 7 in a one-to-one correspondence, and the two synchronous wheels 5 in one group are connected by a synchronous belt 6, and the two synchronous wheels 5 in one group are fixedly connected to the ends of the two threaded rods 7 in one group in a one-to-one correspondence, and one synchronous wheel 5 in one group is connected to the driving motor 4 through a coupling;

[0042] The motor bracket 11 with an L-shaped structure is fixedly connected between the mounting plate 18 and the end cover of the driving motor 4 , and the output end of the driving motor 4 passes through the motor bracket 11 and is rotatably connected to the motor bracket 11 .

[0043] In this embodiment: by starting the driving motor 4, the driving motor 4 drives a synchronous wheel 5 to rotate through a coupling, and the synchronous wheel 5 drives another synchronous wheel 5 to rotate synchronously in the same direction through a synchronous belt 6. The two synchronous wheels 5 can drive two threaded rods 7 in a group to rotate synchronously in the same direction. Since the position where the movable beam 2 is connected to the threaded rod 7 is provided with an internal thread that engages with the threaded rod 7, the movable beam 2 can move along the X-axis, Y-axis and Z-axis under the drive of the corresponding driving mechanism, thereby driving the middle section of the specimen 3 to move, forcing the specimen 3 to deform.

[0044] Please refer to Figure 1 and Figure 2, the first support mechanism is used to support the driving mechanism of the X-axis. The first support mechanism includes: a first support platform 8, a support chute 10, a telescopic unit 16, and a slider 17;

The driving motor 4 in the driving mechanism arranged along the Y-axis drives the motor bracket 11, and the motor bracket 11 drives the slider 17 to move along the X-axis along the support chute 10 in the second support mechanism;

[0053] When the driving mechanism on the Z-axis operates, the movable beam 2 moves up and down at this time, forcing the specimen 3 to deform in the up and down directions.

The connecting chute 15 is opened on the top of the fourth support platform 14 and recessed downward, and the top end of the vertical rod 13 is slidably connected to the inner cavity of the connecting chute 15 along the Y-axis.

[0057] In this embodiment: When the driving mechanism on the X-axis operates, the movable beam 2 moves left and right at this time, forcing the specimen 3 to deform. At this time, the driving mechanism arranged along the Z-axis slides along the third support mechanism driven by the movable beam 2. The driving motor 4 in the driving mechanism arranged along the Z-axis drives the motor bracket 11, and the motor bracket 11 drives the slider 17 to move along the X-axis along the support chute 10 in the third support mechanism;

[0058] When the driving mechanism on the Y-axis operates, the movable beam 2 moves back and forth at this time, forcing the specimen 3 to deform in the back and forth directions. At this time, the driving mechanism arranged along the Z-axis drives the third support mechanism to move back and forth driven by the movable beam 2, and the third support platform 12 drives the vertical rod 13 to move back and forth along the connecting chute 15 during the back and forth movement.

[0062] In this embodiment: during the operation of the driving mechanism along the Z-axis, the driving movable beam 2 is driven to move up and down, thereby driving the driving mechanisms along the X-axis and Y-axis to act in the up and down directions. At this time, the telescopic unit 16 receives a downward pressure or an upward pulling force, and the telescopic unit 16 acts, so that the driving mechanisms along the X-axis and Y-axis act synchronously with the driving mechanism along the Z-axis.
