Description

Technical Field

[0001] The utility model relates to the technical field of building detection, in particular to a rapid detection instrument for the thickness of building floor slabs. Background Art

[0002] Building floor slabs are load-bearing structural members that horizontally separate the upper and lower spaces in multi-story buildings. They are primarily composed of materials such as concrete and steel. They bear and transmit vertical and horizontal loads, and also provide a degree of sound insulation, fire protection, and waterproofing. They primarily consist of three parts: the floor structure layer, the floor surface layer, and the ceiling at the base of the slab. The thickness of the floor slab is typically designed based on national mandatory standards and specifications to ensure not only structural stability and load-bearing capacity, but also the functional and durability requirements of the building.

[0003] Testing building floor slab thickness is crucial to ensuring a building's structural safety, functionality, and durability. On the one hand, insufficient floor slab thickness can lead to insufficient structural load-bearing capacity, cracks, or even collapse, seriously threatening occupant safety. On the other hand, insufficient floor slab thickness can also affect sound insulation and thermal insulation, reducing living comfort. Furthermore, floor slab thickness testing can prevent accidents by identifying potential quality issues early and enabling timely repairs to avoid future safety hazards.

[0004] The floor thickness detection device, filed with application number 201921293778.0 (grant publication number CN210374975U), comprises a handheld detector, a receiving probe, and a transmitting probe, mounted on the upper and lower surfaces of a building floor. The receiving and transmitting probes are aligned vertically, and the handheld detector and receiving probe are wirelessly connected. This utility model addresses the shortcomings of existing technologies by providing a floor thickness detection device with a simple and rational structure that can quickly and accurately measure the thickness of building floor slabs.

[0005] However, when using the building floor thickness detector, it is necessary to detect multiple different sampling points on the floor. When the installation position of the transmitting probe on the lower layer of the floor is changed, it is necessary to move the receiving probe on the upper layer by hand so that the installation positions of the receiving probe and the transmitting probe are aligned up and down, resulting in a long detection time and low efficiency.

The rotating seat 12 and the support seat 21 are respectively provided with a bracket 14 and a bracket 2 22, and a moving mechanism is provided between the bracket 14 and the bracket 2 22. A fifth electric push rod 25 is provided on the top of the moving mechanism, and a transmitting probe 3 34 is provided at the telescopic end of the fifth electric push rod 25.

The controller 20 adopts a low-power microprocessor with model STM32-L0.

[0026] When the detector is detecting the thickness of the floor slab 1, first place the second electric push rod 19 and the base 9 directly below the position to be detected, then start the second electric push rod 19, the telescopic end of the second electric push rod 19 extends, driving the rotating seat 12 to rise, and when the top surface of the rotating seat 12 is close to the bottom surface of the floor slab 1, start the first electric push rod 8, the telescopic end of the first electric push rod 8 extends to drive the transmitting probe 27 to rise, so that the top surface of the transmitting probe 27 abuts against the bottom surface of the floor slab 1, and at the same time set the fourth electric push rod 24 on the ground on one side of the second electric push rod 19, then start the fourth electric push rod 24, the telescopic end of the fourth electric push rod 24 extends to drive the support seat 21 rises. When the top surface of the support seat 21 and the top surface of the rotating seat 12 are flush with each other, the third electric push rod 23 is started.

The first motor 11 adopts a stepping motor that can accurately control the rotation angle. The bottom surface of the rotating seat 12 is provided with a ring groove 31, and the inner wall of the ring groove 31 is provided with a gear ring 29. The gear 30 is engaged with the gear ring 29.

[0029] The driving mechanism is used to drive the rotating base 12 to rotate. When the first motor 11 is started, the first motor 11 rotates to drive the gear 30 to rotate, and the gear 30 rotates to drive the gear ring 29 to rotate, thereby driving the rotating base 12 to rotate a preset angle.

[0030] Preferably, the moving mechanism includes a screw rod 15, a slide rod 16, a second motor 13 and a moving block 17. The screw rod 15 is rotatably arranged between bracket one 14 and bracket two 22, one end of which is rotatably connected to bracket two 22, and the other end passes through bracket one 14 and is driven to the second motor 13.

The slide rod 16 is arranged between bracket one 14 and bracket two 22. The moving block 17 is arranged on the screw rod 15 and is slidably connected to the slide rod 16.

[0031] The moving mechanism is used to drive the moving block 17 to move. When the moving mechanism is started, the second motor 13 is started first. The second motor 13 rotates to drive the screw rod 15 to rotate, thereby driving the moving block 17 to move along the axis of the screw rod 15.

[0032] Preferably, a display screen 35 is further included, which is arranged on the side of the handheld detector 7 and is electrically connected to the controller 20.

[0033] The display screen 35 is used to display the distance between the transmitting probe 27 and the receiving probe 2, the distance between the transmitting probe 34 and the transmitting probe 27, and the angle at which the driving mechanism drives the rotating seat 12 to rotate. The operator located on the floor 1 can obtain the thickness of the floor 1 according to the display screen 35. When changing the detection position, the operator pulls the scale rope 5 to a corresponding length and rotates the receiving probe 2 to a relative angle according to the information on the display screen 35, so as to quickly align the receiving probe 2 and the transmitting probe 34, thereby quickly completing the detection, saving time, and improving detection efficiency.

[0035] An operator on the upper level of floor 1 can control the movement distance of moving block 17 using first and second buttons 36, 37. When first button 36 is pressed, first motor 11 begins forward rotation, and display 35 simultaneously displays the movement distance of moving block 17. Similarly, when second button 37 is pressed, first motor 11 begins reverse rotation, and display 35 simultaneously displays the movement distance of moving block 17, causing transmitting probe 3 34 to move a preset distance. Knob 38 can be used to control the rotation angle of rotating base 12. Clockwise rotation of knob 38 controls forward rotation of second motor 13, while counterclockwise rotation of knob 38 controls reverse rotation of second motor 13, causing rotating base 12 to rotate a preset angle, thereby driving transmitting probe 3 34 to a preset position.

[0036] Preferably, a coil spring 28 is further included, and the coil spring 28 is arranged opposite to the top surface of the rotating seat 12 .

[0037] When the telescopic end of the second electric push rod 19 extends, it drives the rotating seat 12 to rise, so that the top surface of the coil spring 28 and the bottom surface of the floor 1 abut against each other and produce a certain amount of deformation, thereby generating a pre-tightening force, so that the second electric push rod 19 provides stable support for the transmitting probe 27.

[0038] Preferably, it further includes a support block 32, which is arranged on the bottom surface of the base 9 and is made of rubber.

[0039] The support block 32 is made of rubber material, which has good elasticity and wear resistance, increases the friction between the base 9 and the ground, plays an anti-slip role, and also extends the service life of the detector.
