Description

Technical Field

[0001] This utility model relates to the field of building engineering measurement equipment technology, specifically a device for measuring the thickness of cast-in-place concrete floor slabs. Background Technology

[0002] Cast-in-place concrete is a concrete structure formed by erecting formwork in situ and pouring it monolithically on-site. Its core processes include formwork erection, rebar tying, concrete pouring, curing, and formwork removal. It has advantages such as strong integrity and good seismic performance. Floor slab thickness refers to the thickness of a reinforced concrete floor slab from its surface to its bottom after pouring.

[0003] The current method for testing floor slab thickness involves an inspector using an impact drill to vertically drill through the floor slab at the point to be tested. A rigid plate is then used to push the drilled hole upwards from the next floor, ensuring the plate is in close contact with the bottom of the slab. A depth caliper is then used to measure the distance between the bottom and top of the hole. This testing method involves inspecting the floor slab after the concrete has hardened.

[0004] During the measurement process,

[0005] Therefore, we propose to design a device for measuring the thickness of cast-in-place concrete floor slabs. Utility Model Content

[0006] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A device for measuring the thickness of cast-in-place concrete floor slabs includes a base, a platform fixedly connected to the top of the base, a threaded rod threadedly connected to the outer wall of the platform, a knob fixedly connected to the outer end of the threaded rod, and a damping plate rotatably connected to the threaded rod through the platform.

[0009] A measuring tube is slidably connected through the base. The outer wall of the measuring tube is provided with scale lines. A movable rod is slidably connected inside the measuring tube. A cap is rotatably connected to the top of the movable rod. A cone is fixedly connected to the bottom of the movable rod. Sliding grooves are opened on both sides of the cone. A movable plate is slidably connected inside the sliding grooves.

[0010] In a preferred embodiment of the cast-in-place concrete floor slab thickness measuring device described in this utility model, a handle is fixedly connected to the outer wall of the measuring tube to facilitate the lifting of the measuring tube by construction personnel.

[0011] In a preferred embodiment of the cast-in-place concrete slab thickness measuring device of the present invention, a threaded ring is fixedly connected to the outer wall of the top of the measuring tube, and an annular groove corresponding to the threaded ring is opened at the bottom of the cover near the edge. The annular groove is threadedly connected to the threaded ring. When the movable rod is further extended into the measuring tube, rotating the cover can make the cover threadedly connected to the threaded ring, thereby fixing the position of the internal movable rod.

[0012] As a preferred embodiment of the cast-in-place concrete floor slab thickness measuring device of this utility model, the measuring tube has through holes on both sides corresponding to the movable plate. The movable plate extends outward through the through holes, and by extending outward through the movable plate, it can be used as a rigid plate in the prior art to position the bottom of the floor slab.

[0013] In a preferred embodiment of the cast-in-place concrete slab thickness measuring device of this utility model, the damping plate is in contact with the outer wall of the measuring tube. By turning the knob to drive the screw to rotate, the damping plate can be tightly in contact with the outer wall of the measuring tube, which facilitates the fixing of the measuring tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes the cooperation between the base, measuring tube, movable rod, and scale line to eliminate the need for construction personnel to work on the support plate at the bottom of the floor slab. This allows for single-person operation of floor slab thickness measurement, saving significant time and manpower and increasing the speed of floor slab thickness measurement.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-3 This utility model provides a device for measuring the thickness of cast-in-place concrete floor slabs, including a base 1, a base platform 2 fixedly connected to the top of the base 1, a screw rod 10 threadedly connected to the outer wall of the base platform 2, a knob 11 fixedly connected to the outer end of the screw rod 10, and a damping plate 12 rotatably connected to the screw rod 10 through the base platform 2.

[0025] The damping plate 12 is attached to the outer wall of the measuring tube 3. By turning the knob 11 to drive the lead screw 10 to rotate, the damping plate 12 can be tightly attached to the outer wall of the measuring tube 3, which facilitates the fixation of the measuring tube 3.

[0026] The base 2 has a sliding connection through which a measuring tube 3 is connected. The outer wall of the measuring tube 3 is provided with a scale line 4. The outer wall of the measuring tube 3 is fixedly connected with a handle 301, which makes it easy for construction personnel to lift the measuring tube 3.

[0027] A movable rod 5 is slidably connected inside the measuring tube 3. A cover 6 is rotatably connected to the top of the movable rod 5. A threaded ring 302 is fixedly connected to the outer wall of the top of the measuring tube 3. An annular groove corresponding to the threaded ring 302 is opened at the bottom of the cover 6 near the edge. The annular groove is threadedly connected to the threaded ring 302. When the movable rod 5 is further extended into the measuring tube 3, rotating the cover 6 can make the cover 6 threadedly connected to the threaded ring 302, thereby fixing the position of the internal movable rod 5.

[0028] The bottom of the movable rod 5 is fixedly connected to a cone 7. Both sides of the cone 7 are provided with sliding grooves 8. A movable plate 9 is slidably connected inside the sliding grooves 8. Both sides of the measuring tube 3 are provided with through holes corresponding to the movable plate 9. The movable plate 9 passes through the through holes and extends outward. By extending outward through the movable plate 9, it can serve as a rigid plate in the prior art to position the bottom of the floor slab.

[0029] When using it, first drill a through hole in the floor slab with an impact drill, then place the base 1 on the floor slab, measure the top surface of the base 1 with a level, and put a wooden piece under the base 1 to level it.

[0030] After leveling, insert the measuring tube 3 into the through hole drilled by the drill bit and extend it downwards. Once the head of the measuring tube 3 passes through the floor slab, press the cover 6 to drive the movable rod 5 to descend in the measuring tube 3. During the descent, the movable plate 9 can slide on the outer wall of the cone 7 and is gradually squeezed outwards. The movable plate 9 is slidably connected to the slide groove 8. The part located in the slide groove 8 is provided with a limit to prevent the movable plate 9 from coming out. After pressing the cover 6 into place, screw the cover 6 into the threaded connection with the threaded ring 302 to fix the position of the movable plate 9.

[0031] At this point, pull the measuring tube 3 upwards again. When it cannot be pulled up, it means that the movable plate 9 is in contact with the bottom of the floor slab. Turn the knob 11 to drive the screw 10 to rotate, so that the damping plate 12 is tightly attached to the outer wall of the measuring tube 3. Combined with the inner wall of the base 2, the position of the measuring tube 3 is clamped and fixed.

[0032] Finally, by measuring the scale line 4 on the outer wall of the measuring tube 3, which has already eliminated errors inherent to the equipment such as the thickness of the movable plate 9 during its setting, the reading position is the position of the scale line 4 corresponding to the top surface of the base 2. Thus, the reading of the scale line 4 at this time represents the thickness of the floor slab. No construction personnel are required to go downstairs to assist; it can be operated by a single person, saving manpower and time, and improving the speed of floor slab thickness measurement.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
