Description

Technical Field

[0001] The utility model belongs to the technical field of concrete floor thickness measurement, and particularly relates to an adjustable concrete floor thickness measurement detector. Background Technique

[0002] The concrete floor is one of the very important structural components in the building structure. Specifically, the concrete floor is a load-bearing structure that bears the weight of people and objects in the house. Therefore, relatively high performance requirements are imposed on the concrete floor, and the thickness of the floor is one of the important indicators reflecting the load-bearing capacity of the floor.

[0003] Therefore, during the building construction process, especially during the subsequent acceptance process of the building, it is necessary to detect the thickness of the floor. At present, the detection method for the thickness of the floor is to use a thickness sensor, and the detection method is: place the thickness sensor on the top surface and the bottom surface of the floor respectively. The top surface of the floor is the ground of the upper-side house, and the bottom surface of the floor is the ceiling of the lower-side house.

[0004] Therefore, during the detection process, it is relatively convenient to place the sensor on the top surface of the floor, while it is relatively difficult to place it on the bottom surface of the floor. Especially when the indoor height of the house is relatively large, during the detection process, the operator needs to tie the sensor to a support rod and press the sensor against the ceiling.

[0005] However, during the detection process, it is often necessary to perform multi-point detection on multiple positions in the detection area to ensure that the detected data value can accurately reflect the thickness of the floor. Therefore, the operator needs to continuously move the position of the sensor on the ceiling by holding a long support rod.

[0006] Obviously, during the detection process with a high support rod, it is not only laborious, but also extremely easy to cause the thickness sensor not to be closely attached to the floor surface. Specifically, after the operator holds the detection for a long time and the arm aches, the lifting force of the arm will be unconsciously reduced, and then the height of the support rod will be reduced. Due to the sensor not being able to closely adhere to the floor surface, the detection data often appears incorrect.

[0007] Moreover, for multi-point sampling detection, the method of holding the sensor by hand is not only extremely inefficient, has a high data error rate, but also has very poor operation flexibility. Specifically, when holding the bottom of the support, due to the small force arm, a relatively large lifting force is required, which leads to inflexible operation when moving.

[0040] Embodiment 1

[0041] As Figures 1-5 shown, an adjustable concrete floor thickness measuring detector includes a lower roller frame 1 (the longitudinal cross-sectional shape of the lower roller frame 1 is trapezoidal and is formed by welding steel frames). In order to facilitate the pushing of the device and realize the convenient movement of the detection position during the detection process, a pair of rollers 11 are respectively installed on both sides of the bottom of the lower roller frame 1 (the pair of rollers 11 are respectively located on the front and rear sides). Specifically, in the same installation manner as the existing rollers 11, roller seats for rotatably connecting the rollers 11 are respectively fixedly connected to both sides of the bottom of the lower roller frame 1 (the wheel axles of the rollers 11 are rotatably connected to the roller seats).

[0042] A long telescopic adjustment mechanism is assembled and connected to the above-mentioned lower roller frame 1. The specific structure is as follows: The long telescopic adjustment mechanism includes a lower adjustment tube 21 threadedly connected to the lower roller frame 1 (the outer side wall of the lower adjustment tube 21 has a threaded structure, and the inner wall of the tube cavity of the lower adjustment tube 21 has a threaded structure). The lower adjustment tube 21 is threadedly connected to an upper adjustment rod 22 (which has an external threaded structure). The top of the upper adjustment rod 22 is rotatably connected to the top seat 23 (according to the existing rotational connection method, a limiting sleeve for rotatably connecting the upper end position of the upper adjustment rod 22 is fixedly connected to the bottom of the top seat 23, and the upper end position of the upper adjustment rod 22 is a smooth part).

[0043] Meanwhile, a driving handwheel 211 is fixedly connected to the bottom of the lower adjusting pipe 21. The height adjustment method is as follows: First, by rotating the driving handwheel, the lower adjusting pipe 21 is screwed to the lower rolling frame 1 to raise or lower the lower adjusting pipe 21. On both sides of the bottom of the top seat 23, long guide rods 24 that are slidably connected to both sides of the lower rolling frame 1 are respectively fixedly connected. During height adjustment, the sliding smoothness is achieved by the long guide rods 24 being slidably connected to the lower rolling frame 1.

[0044] Second, adjust the depth of the upper adjusting rod 22 screwed to the lower adjusting pipe 21. Specifically, in order to facilitate screwing the upper adjusting rod 22, a convex rib structure is integrally formed at the lower end of the upper adjusting rod 22. A wrench is used to hold the hexagonal convex rib structure to achieve height adjustment.

[0045] A number of detection sensor mechanisms 3 are fixedly assembled and connected to the top seat 23; specifically, one detection sensor mechanism 3 is installed on each of the front, rear, left, and right side walls of the top seat 23. Taking the top seat 23 as a reference point, simultaneous sampling detection is achieved in four directions on the bottom surface of the floor slab. Furthermore, the number of sampling points is increased to improve the accuracy of the detection data.

[0046] Specifically, the detection sensor mechanism 3 includes a pair of long slide rails 31 fixedly connected to the side wall of the top seat 23, and a slide seat 32 is slidably connected to the long slide rails 31; a thickness detection sensor 34 is fixedly installed on the top of the slide seat 32 through a spring telescopic structure.

[0047] Among them, the thickness detection sensor 34 is a conventional thickness sensor used in the prior art for detecting the thickness of the floor slab.

[0048] During the detection process, the thickness detection sensor 34 abuts against the ground of the floor slab, which is the same as the existing detection method. Another operator holds a detector at the top surface of the floor slab (i.e., inside the upper floor room) and synchronously abuts it against the floor slab for detection.

[0049] Specifically, a telescopic spring 33 is sleeved on the long slide rail 31, and both ends of the telescopic spring 33 are respectively fixedly connected to the side wall of the slide seat 32 and the top seat 23; a pulling rope 351 is fixedly connected to the long slide rail 31.

[0050] Specifically, a downwardly inclined pull rod 35 is fixedly connected to the outer side wall of the slide seat 32, a pull ring is installed at the end of the pull rod 35, and the upper end of the pulling rope 351 is fixedly connected to the pull ring.

[0051] During the detection process, the operator pulls the pulling rope 351 by hand to make each thickness detection sensor 34 - slide seat 32 slide on the long slide rail 31. After sliding to a position point, detection is performed. Then, it slides to the end of the long slide rail 31 again (push the entire device to move the detection position and perform detection again in the same way).

[0052] During the detection process, the four thickness detection sensors 34 can synchronously slide and adjust the detection position. Therefore, during the detection process, it is not only convenient to adjust the position of the thickness detection sensors 34, but also only requires the operator to pull the rope 351 during the inspection process.

[0053] This method enables detection at multiple position points on the floor slab in a relatively short time, thereby improving the detection efficiency. In a short time, a large number of detection values can be obtained, enabling accurate reflection of the thickness of the floor slab.

[0054] Embodiment 2

[0055] As Figures 1-5 shown, on the basis of the structure of Embodiment 1, a pair of hand pressure rods 13 are respectively fixedly connected to the left and right side walls of the lower rolling frame 1, and brackets 12 are respectively hinged to both sides of the bottom of the lower rolling frame 1. The purpose of using the hand pressure rods 13 and brackets 12 is as follows:

[0056] During the detection process, if it is necessary to adjust the angle of the thickness detection sensor 34 (to facilitate abutting the thickness detection sensor 34 against an inclined wall or floor slab), at this time, the operator flips and lowers one side of the bracket 12, such as the left side, and presses down the right hand pressure rod 13 with the hand. Using the right roller 11 as a fulcrum, the entire device is lifted, facilitating the thickness detection sensor 34 to contact the vertical wall. Subsequently, after adjusting the posture, using the brackets 12 and rollers 11 as fulcrums for stable support, it is convenient for detection.

[0057] The hinged manner of the bracket is as follows: A pin rod for hinging the bracket is fixedly connected to the front and rear side walls of the lower rolling frame 1. The pin rod is threadedly connected with a nut. Loosening the nut enables the bracket 12 to be flipped, and tightening the nut after flipping enables the bracket to be fixed under the extrusion of the nut.

[0058] Embodiment 3

[0059] As Figures 1-5 shown, on the basis of the structure of Embodiment 2, the above spring telescopic structure includes a telescopic short rod 342 fixedly connected to the bottom position of the thickness detection sensor 34, and a short sleeve 341 fixedly connected to the top of the sliding seat 32 and slidably connecting the telescopic short rod 342; a socket spring 343 sleeved on the telescopic short rod 342 is fixedly connected to the bottom of the thickness detection sensor 34, and the bottom of the socket spring 343 is fixedly connected to the top of the short sleeve 341.

[0060] Under the elastic force of the socket spring 341, the thickness detection sensor 34 always elastically abuts against the floor slab surface. In this way, it is possible to avoid the existence of a hollow gap between the thickness detection sensor 34 and the bottom surface of the floor slab during the detection process, which affects the accuracy of the detection.

[0061] Of course, the above description is not a limitation to the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present utility model shall also fall within the protection scope of the present utility model.
