Abstract
Description
Technical Field
[0001] The utility model relates to the field of concrete slab thickness detection, in particular to a convenient cast-in-place concrete slab thickness detection device. Background Art
[0002] In the existing construction process, the method for testing the thickness of cast-in-place concrete floor slabs is to place a slab thickness controller, use the steel bar insertion method and the wire pulling method. Such a detection method leads to certain errors in the detection of the floor slab thickness and cannot accurately measure the slab thickness. As a result, after the concrete is poured, the slab thickness does not meet the specification requirements. Floor slabs with large slab thickness deviations are difficult to handle. The conventional method is partial replacement or overall replacement, which often brings great economic losses to the project. Therefore, a more accurate detection method is needed in cast-in-place concrete construction to avoid delays and economic losses caused by rework of construction projects. Utility Model Content
[0003] The purpose of the utility model is to provide a convenient cast-in-place concrete slab thickness detection device, which can solve the technical problem of large errors in existing concrete slab thickness detection, realize more convenient and accurate slab thickness detection of cast-in-place concrete, reduce detection errors, reduce construction delays and economic losses caused thereby, and improve the overall efficiency and quality of construction.
[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:
[0005] A convenient cast-in-place concrete plate thickness detection device comprises a scale rod and a detection rod, wherein the scale rod is provided with scale lines, a clamping ring is fixed on the scale rod, the clamping ring is sleeved on the outside of the detection rod and is slidably connected with the detection rod, a caliper is fixed on the detection rod, the caliper is used in conjunction with the scale lines, a retaining ring is provided on the detection rod and is used in conjunction with the clamping ring, and the retaining ring moves up and down along the detection rod.
[0006] Furthermore, there are two symmetrically arranged snap rings, and the retaining ring is located between the two snap rings.
[0007] Furthermore, the retaining ring is made of elastic rubber material and is sleeved on the outside of the detection rod.
[0008] Furthermore, a cone head is provided at the bottom of the scale rod, and a handle is provided at the top of the scale rod.
[0009] Furthermore, a leveler is provided on the handle.
[0010] Furthermore, a detection plate is provided at the bottom of the detection rod.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The structure of the utility model includes a scale rod and a detection rod. A clamping ring is fixed on the scale rod. The clamping ring is slidably sleeved on the outside of the detection rod, so that the detection rod can slide vertically up and down relative to the detection rod through the clamping ring. At the same time, a caliper used in conjunction with the scale line on the scale rod is fixed on the detection rod. When using such a structure, the bottom of the scale rod is inserted into the bottom of the concrete, and then the detection rod is moved downward to make its bottom move to the surface of the top of the concrete. At this time, the reading of the caliper on the scale line is read. The reading at this time is the slab thickness of the cast-in-place concrete. Such a structure is simple to operate, and the measurement data is more accurate, which reduces the error of slab thickness measurement, reduces the possibility of rework in the later stage, reduces the delay in construction period and economic losses caused by it, and ensures the efficiency and quality of concrete construction.
[0013] 2. When it is necessary to continuously inspect multiple poured concrete plates of the same thickness, the retaining ring on the inspection rod is moved so that it is located a certain distance above the clamping ring to block the clamping ring, thereby limiting the moving distance of the inspection rod relative to the scale rod, so that the relative distance between the two is maintained within a range close to the plate thickness. In subsequent inspections, the inspection rod only needs to move a small distance to achieve rapid measurement of the plate thickness, further simplifying the steps of continuous measurement and improving the efficiency of continuous measurement of the same plate thickness.

[0020] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.
[0021] Reference Figure 1 The utility model is a convenient cast-in-place concrete plate thickness detection device. The main structure includes a scale rod 1 and a detection rod 2. Both are rod-shaped structures. Preferably, metal, wood or plastic materials can be used to avoid corrosion and deterioration and ensure service life. The scale rod 1 is provided with scale lines 3. The unit scale of the scale line 3 is determined according to the requirements of the project construction. Figure 2 A clamping ring 4 is welded or bolted on the scale rod 1, and the clamping ring 4 is sleeved on the outside of the detection rod 2 and slidably connected thereto. The clamping ring 4 includes a fixing portion and a collar portion. The fixing portion is plate-shaped and fixed to the scale rod 1 by welding or bolts. The collar portion is sleeved on the outside of the detection rod 2 and slides up and down along the detection rod 2. Such a structure enables the detection rod 2 to move vertically more accurately relative to the scale rod 1, so that the relative movement distance between the two is more accurate, so that the later measurement of the vertical thickness of the concrete slab is more accurate. Figure 3 A caliper 5 is welded or bolted on the detection rod 2, and the caliper 5 is used in conjunction with the scale line 3. Preferably, one end of the caliper 5 is fixed to the detection rod 2 by welding or bolts, and the other end is also provided with a collar portion, which is sleeved on the outside of the scale rod 1, so that when the caliper 5 moves up and down, its top can better fit with the scale line 3 to ensure the accuracy of the reading of the scale line 3. During the specific detection, the bottom of the scale rod 1 is first inserted into the bottom end of the concrete, and then the detection rod 2 is moved so that the bottom end of the detection rod 2 moves to the top surface of the concrete. When the bottom end of the detection rod 2 and the bottom end of the scale rod 1 are aligned, the caliper 5 coincides with the zero scale of the scale line 3, and the relative movement distance between the two during the detection is the concrete plate thickness. At this time, the scale line 3 corresponding to the caliper 5 can be directly read. To achieve rapid measurement of the plate thickness, the detection rod 2 is provided with a retaining ring 6 used in conjunction with the snap ring 4. The size of the retaining ring 6 protruding from the outside of the detection rod 2 is larger than the snap ring 4, thereby achieving effective blocking of the snap ring 4. The retaining ring 6 moves up and down along the detection rod 2. The setting of the retaining ring 6 can block the snap ring 4. Such a structure allows the retaining ring 6 to be moved to a certain distance above the snap ring 4 or directly contact the top of the snap ring 4 when it is necessary to continuously measure concrete of the same plate thickness, thereby limiting the position of the detection rod 2 relative to the scale rod 1, so that the detection rod 2 only needs to move a short distance in subsequent detection to achieve rapid detection of the plate thickness, making the continuous detection of the concrete plate thickness more convenient and accurate, and improving the efficiency of continuous detection.
[0022] Preferably, there are two symmetrically arranged retaining rings 4, and the retaining ring 6 is located between the two retaining rings 4. Such a structure ensures that when the detection rod 2 moves relative to the scale rod 1, there are contact points at the positions of the two retaining rings 4, thereby making the structure of the detection rod 2 more stable when moving relative to the scale rod 1, and not easy to tilt relative to the scale rod 1, thereby making the measurement of the plate thickness more accurate and further reducing the measurement error.
[0023] Preferably, refer to Figure 4 The retaining ring 6 is made of elastic rubber material and is sleeved on the outside of the detection rod 2. This structure allows the retaining ring 6 to be moved manually, making the operation more convenient. At the same time, the elastic rubber material can be automatically fixed on the detection rod 2 under the action of elastic force after moving to the specified position, making the movement and fixing operation of the retaining ring 6 more convenient.
[0024] Preferably, a cone head 7 is provided at the bottom of the scale rod 1, so that the bottom of the scale rod 1 can be inserted into the concrete more smoothly, the resistance during insertion is reduced, the interference with the poured concrete is reduced, and the convenience and fluency of the detection operation are improved. A handle 8 is welded or integrally formed on the top of the scale rod 1, and the handle 8 can be held by hand during operation, which is more convenient for applying force, making the operation of inserting the scale rod 1 into the concrete more convenient.
[0025] Preferably, a level 9 is provided on the handle 8, and the level 9 can adopt the structure of a bubble level commonly used in the existing mechanical industry, so that the scale rod 1 is inserted vertically, thereby further reducing the measurement error.
[0026] Preferably, a detection disk 10 is provided at the bottom of the detection rod 2, and the cross-sectional area of the detection disk 10 is larger than the cross-sectional area of the detection rod 2, so that when the bottom of the detection rod 2 contacts the surface of the top of the concrete, the detection disk 10 contacts the concrete, thereby avoiding the bottom of the detection rod 2 from being inserted into the concrete, allowing the detection disk 10 to better fit the surface of the concrete, making the detection data of the concrete more accurate.
[0027] Working principle: The structure of the utility model includes a scale rod 1 and a detection rod 2. A clamping ring 4 is fixed on the scale rod 1. The clamping ring 4 is slidably sleeved on the outside of the detection rod 2, so that the detection rod 2 can slide vertically up and down relative to the detection rod 2 through the clamping ring 4. At the same time, a caliper 5 used in conjunction with the scale line 3 on the scale rod 1 is fixed on the detection rod 2. When using such a structure, the bottom of the scale rod 1 is inserted into the bottom of the concrete, and then the detection rod 2 is moved downward so that its bottom moves to the surface of the top of the concrete. At this time, the reading of the caliper 5 on the scale line 3 is read. The reading at this time is the slab thickness of the cast-in-place concrete. Such a structure is simple to operate, the measurement data is more accurate, and the slab thickness is reduced. The measurement error is reduced, the possibility of rework in the later stage is reduced, the resulting delays in construction period and economic losses are reduced, and the efficiency and quality of concrete construction are guaranteed; when it is necessary to continuously inspect multiple poured concrete plates of the same thickness, the retaining ring 6 on the inspection rod 2 is moved to be located a certain distance above the clamping ring 4 to block the clamping ring 4, thereby limiting the moving distance of the inspection rod 2 relative to the scale rod 1, so that the relative distance between the two is maintained within a range close to the plate thickness, so that in subsequent inspections, the inspection rod 2 only needs to move a smaller distance to achieve rapid measurement of the plate thickness, further simplifying the steps of continuous measurement and improving the efficiency of continuous measurement of the same plate thickness.
