Description

Technical Field

[0001] The utility model relates to an improved structure of a floor slab thickness insertion dowel measurement controller. Background Art

[0002] The existing concrete floor thickness plunger measuring controller is manufactured according to the different thicknesses of the concrete floor. The plunger measuring controllers of different floor thicknesses are respectively manufactured. When pouring concrete, the pouring thickness of the concrete floor is guaranteed by the plunger measuring control. However, the drawback is that it is necessary to manufacture the plunger measuring controllers of various sizes. When pouring concrete, if it is necessary to plunge plungers into concrete floors of different measuring thicknesses, the improved structure of the floor thickness plunger measuring controller needs to be frequently adjusted. At present, the adjustment operation of the improved structure of the floor thickness plunger measuring controller is cumbersome and inconvenient for users to operate. Utility Model Content

[0003] The utility model aims to provide an improved structure of a floor slab thickness insertion dowel measurement controller which can adapt to the insertion dowel measurement of concrete floor slabs of different thicknesses, is easy to use and has more convenient scale observation.

[0004] The purpose of the utility model is achieved in this way:

[0005] An improved structure of a floor thickness insertion measurement controller, comprising an outer sleeve, an inner core and a controller, wherein the inner core comprises a rod body and a lower end head, the lower end head is fixed to the lower end of the rod body, and the rod body is provided with a transverse channel;

[0006] The outer sleeve comprises a cylinder and a measuring control disk, wherein the measuring control disk is fixed at the lower end of the cylinder, through holes are provided at intervals on the back of the cylinder along its length direction, and vertical slide grooves are provided on the front of the cylinder along its length direction;

[0007] The rod body is placed in the inner cavity of the cylinder in a sliding manner, and the inner core and the outer sleeve are slidably connected;

[0008] The controller is inserted into the corresponding through hole through the vertical slide groove and the transverse channel, so that the controller locks the relative sliding state between the inner core and the outer shell.

[0009] After the user learns the thickness required by the design drawing of the concrete floor to be measured, the user moves the inner core and adjusts the improved structure of the floor thickness plunger measurement controller to the thickness required by the design drawing of the concrete floor to be measured, and then makes the controller lock the relative sliding state between the inner core and the outer shell. Then the user inserts the improved structure of the floor thickness plunger measurement controller into the unsolidified concrete floor until the lower end of the lower end abuts against the bottom surface of the unsolidified concrete floor. At this time, the user observes the measurement control disk. If the bottom surface of the measurement control disk is horizontally attached to the surface of the unsolidified concrete floor, the measured concrete floor reaches the thickness required by the design drawing. If the surface of the unsolidified concrete floor is smaller than the bottom surface of the measurement control disk, the thickness of the measured concrete floor is smaller than the bottom surface of the measurement control disk. For the thickness required by the design drawings, if the surface of the unsolidified concrete slab is larger than the measuring control disk, the thickness of the measured concrete slab is greater than the thickness required by the design drawings. At this time, when the workers measure a thickness greater than or less than the thickness required by the design drawings, they can adjust the thickness of the unsolidified concrete slab in time, and make up for it by thinning and thickening, so that the thickness of the concrete slab meets the requirements of the design drawings. The improved structure of the floor slab thickness plug-in measurement controller can be used for rapid measurement, and the improved structure of the floor slab thickness plug-in measurement controller is suitable for measuring concrete slabs of various thicknesses. The measurement is convenient and quick. After the measurement is completed, the concrete is prevented from sticking to the improved structure of the floor slab thickness plug-in measurement controller, and the user can rinse it with clean water for easy use next time.

[0010] After the user learns the thickness required by the design drawings of the concrete floor to be measured, the user moves the controller so that the controller leaves the corresponding through hole, thereby releasing the relative locking state between the inner core and the outer shell. At this time, the inner core and the outer shell can slide relative to each other. Then the user moves the controller up and down, and the controller slides along the vertical slide groove, so that the controller drives the inner core to move until the height of the measurement control panel is adjusted to meet the thickness required by the design drawings of the concrete floor to be measured. Finally, the user moves the controller so that the controller is inserted into the corresponding through hole, thereby locking the relative sliding state between the inner core and the outer shell, and completing the height adjustment of the measurement control panel. This operation method allows the user to quickly adjust the improved structure of the floor thickness insertion measurement controller in a short time, thereby improving work efficiency.

[0011] When the concrete slab measured by the plunger is not too thick and the inner core is not subjected to much reaction force, a through-hole limiting controller (forming a support point) is used. This solution is adopted while ensuring that the pin and jacket of the controller are not deformed.

[0012] The purpose of the utility model can also be solved by the following technical measures:

[0013] Furthermore, a line connecting the center point of the through hole and the center line of the vertical slide groove passes through the center of the cylinder.

[0014] Inserting and sliding the controller is easier and smoother. Users don’t have to struggle to find the right position, they just need to insert it along the straight track.

[0015] Furthermore, a vertical slide groove is provided on the front side of the cylinder along its length direction, and transverse slide grooves are arranged at intervals on the front side of the cylinder along its length direction, and the transverse slide grooves are connected to the vertical slide grooves.

[0016] Improved stability: After the improved structure of the floor thickness measuring controller is adjusted, the user moves the controller so that the front end of the controller enters the horizontal slide and the rear end of the controller enters the corresponding through hole, forming two support points for supporting the controller. This design can provide two points of support when the inner core is inserted into the concrete floor. When the inner core is inserted into a thicker concrete floor and the reaction force is large, the controller's latch and jacket are not easily deformed.

[0017] Enhanced applicability: This design is particularly suitable for measuring deeper concrete slabs, because the controller has two supporting points, which can better support and stabilize the inner core, so that the pin and outer sleeve are not easily deformed during the measurement process, making it suitable for measuring deeper concrete slabs.

[0018] Furthermore, the width of the transverse slide groove is the same as the width of the vertical slide groove, and the end of the transverse slide groove is a semicircular opening.

[0019] Furthermore, a line connecting the center lines of the first through hole and the last through hole on the back of the cylinder and the center line of the vertical slide groove passes through the center of the cylinder, and a line connecting the center lines of the remaining through holes between the first through hole and the last through hole and the center of the semicircular opening of the horizontal slide groove passes through the center of the cylinder.

[0020] When the concrete floor is thicker, the controller is restricted by through holes and transverse slides to form two support points (when the front end of the controller is in the transverse slide and the rear end enters the corresponding through hole). Under this solution, the inner core can withstand a larger reaction force when inserted into the concrete. Compared with the solution with one support point (when the rear end of the controller enters the corresponding through hole), it can withstand a larger reaction force and can measure thicker floors by inserting a dowel.

[0021] Furthermore, a non-slip handle cover is sleeved on the upper part of the cylinder. The non-slip handle cover is provided to facilitate users to hold the floor thickness drilling measurement controller to improve the structure.

[0022] Furthermore, a blocking block is provided on the inner wall of the transverse channel, and the blocking block divides the transverse channel into a first channel section and a second channel section, and the width of the second channel section is smaller than the width of the first channel section.

[0023] Furthermore, the controller includes a latch, a spring, a nut and a handle, the head size of the latch is larger than the tail size, the tail of the latch passes through the through hole, the first channel section, the second channel section and extends out of the vertical slide groove to connect with the nut, the spring is sleeved on the tail of the latch, the spring is placed in the first channel section, one end of the spring abuts against the head of the latch, and the other end of the spring abuts against the blocking block, the spring constitutes a reset mechanism of the latch, and the handle and the nut are fixedly connected.

[0024] Easy to disassemble and clean: The design of the controller allows the user to disassemble it for cleaning. This feature allows the controller to be cleaned and maintained regularly, keeping it clean and in good working condition, extending its service life.

[0025] Easy to operate: The user only needs to pull the handle to move the bolt so that the head of the bolt leaves the through hole. This operation is simple and intuitive, allowing the user to easily unlock the outer shell and inner core without the need for additional tools or complicated operating steps.

[0026] Automatic reset function: When the user releases the handle, the spring will automatically drive the latch to move, so that the head of the latch is inserted into the corresponding through hole, completing the locking of the outer sleeve and the inner core, and the operation is simple.

[0027] Simplified maintenance: Users can easily disassemble and clean each part of the controller without specialized skills or tools. This simplified maintenance process saves time and effort, making it more convenient for users to keep the controller clean and in good condition.

[0028] Furthermore, the width of the vertical slide groove is the same as the width of the horizontal slide groove, and the width of the vertical slide groove and the width of the horizontal slide groove are both smaller than the width of the through hole.

[0029] The width of the vertical slide groove and the horizontal slide groove are both smaller than the width of the through hole, and the width of the vertical slide groove and the horizontal slide groove are slightly larger than the width of the tail of the bolt and smaller than the width of the head of the bolt. The width of the through hole is slightly larger than the width of the head of the bolt, so that the head of the bolt can be easily inserted into the corresponding through hole. This design ensures the accurate positioning of the bolt and improves the convenience and fluency of operation.

[0030] Furthermore, a scale is provided on the back of the cylinder body next to the through hole, the scale values ​​of the scale increase from top to bottom, and the adjacent scale values ​​are 10 mm apart, the interval between the adjacent through holes is 10 mm, and the outer wall of the cylinder that is 500 mm larger than the measurement control panel is provided with a 500 mm scale value. The improved structure of the floor thickness plunger measurement controller can not only measure the thickness of the concrete floor, but also measure the elevation of the concrete floor by drawing a line on the wall column steel bar (500 mm elevation line above the concrete floor), thereby improving the practicality of the improved structure of the floor thickness plunger measurement controller.

[0031] Furthermore, the position of the scale value corresponds to the position of the center line of the corresponding through hole.

[0032] Furthermore, the lower end of the lower end head is circular, semicircular or pointed.

[0033] When used to measure the thickness of road concrete (the base layer below the road concrete surface layer is a soil or gravel base layer), the lower end of the lower end head is semicircular to prevent the lower end of the lower end head from being inserted into the gravel or soil base layer, thereby improving the measurement accuracy.

[0034] The beneficial effects of the utility model are as follows:

[0035] According to the utility model, after the user learns the thickness required by the design drawing of the concrete floor to be measured, the user moves the controller so that the head of the pin of the controller leaves the corresponding through hole, thereby allowing the controller to release the relative locking state between the inner core and the outer sleeve. At this time, the inner core and the outer sleeve can slide relatively to each other. Then the user moves the controller up and down, and the controller slides along the vertical slide groove, so that the controller drives the inner core to move until the height of the measurement control plate is adjusted to meet the thickness required by the design drawing of the concrete floor to be measured. Finally, the user moves the controller so that the controller is inserted into the corresponding through hole, thereby allowing the controller to lock the relative sliding state between the inner core and the outer sleeve, and completes the height adjustment of the measurement control plate. This operation method allows the user to quickly adjust the improved structure of the floor thickness insertion rod measurement controller in a short time, thereby improving work efficiency.

[0036] In the utility model, the head of the latch enters the through hole corresponding to the outer sleeve, and the tail of the latch extends out of the vertical slide groove of the outer sleeve to complete the locking of the outer sleeve and the inner core. When the head of the latch leaves the through hole corresponding to the outer sleeve, the tail of the latch extends out of the vertical slide groove of the outer sleeve to complete the unlocking of the outer sleeve and the inner core. In the unlocked state, when the user adjusts the relative position of the outer sleeve and the inner core, the user drives the handle to move along the vertical slide groove of the outer sleeve. When reaching the appropriate position, the user moves the controller to insert the head of the latch into the corresponding through hole. The operation is simple and the height of the control panel can be quickly adjusted. In addition, when the outer sleeve and the inner core are locked, the head of the latch is inserted into the through hole to form a first supporting point to withstand the reaction force during the insertion process and ensure the measurement effect.

[0037] According to the utility model, after the user learns the thickness required by the design drawing of the concrete floor to be measured, the user moves the controller so that the head of the pin leaves the corresponding through hole, thereby allowing the controller to release the relative locking state between the inner core and the outer sleeve. At this time, the inner core and the outer sleeve can slide relatively to each other, and then the user moves the controller up and down, and the controller slides along the vertical slide groove, so that the controller drives the inner core to move until the height of the measurement control panel is adjusted to meet the thickness required by the design drawing of the concrete floor to be measured. Finally, the user moves the controller so that the head of the pin is inserted into the corresponding through hole, and the tail of the pin enters the horizontal slide groove, thereby allowing the controller to lock the relative sliding state between the inner core and the outer sleeve, and complete the height adjustment of the measurement control panel. This operation method allows the user to quickly adjust the improved structure of the floor thickness plunger measurement controller in a short time, thereby improving work efficiency.

[0038] The utility model has the following steps: the head of the latch enters the through hole corresponding to the outer sleeve, and the tail of the latch extends out of the horizontal slide groove of the outer sleeve to complete the locking of the outer sleeve and the inner core. When the head of the latch leaves the through hole corresponding to the outer sleeve, the tail of the latch extends out of the vertical slide groove of the outer sleeve to complete the unlocking of the outer sleeve and the inner core. In the unlocked state, when the user adjusts the relative position of the outer sleeve and the inner core, the user drives the handle to move along the vertical slide groove of the outer sleeve. When the appropriate position is reached, the user moves the controller to insert the head of the latch into the corresponding through hole, and the tail of the latch enters the horizontal slide groove. The operation is simple and the height of the control panel can be quickly adjusted. In addition, when the outer sleeve and the inner core are locked, the head of the latch and the inserted through hole form a first support point, and the tail of the latch enters the horizontal slide groove to form a second support point. Under the action of the two support points, a greater reaction force can be borne during the insertion process.

[0039] The utility model adopts a through-hole limiting controller solution (forming the first supporting point) when the concrete floor is not too thick. Under this solution, the reaction force borne by the inner core when inserted into the concrete is not large. Therefore, when the concrete floor is not too thick, only one supporting point is needed to ensure that the latch and the outer sleeve are not deformed, which makes the user operation more convenient.

[0040] In the present invention, when the concrete floor is thick, a through hole and a transverse slide groove are used to jointly limit the controller (forming two supporting points). Under this solution, the reaction force borne by the inner core when inserted into the concrete is relatively large. The two supporting points make it easier to ensure that the pin and the outer sleeve are not easily deformed. The inner core can be inserted into thicker concrete floor, thereby improving the application range of the floor thickness insertion measurement controller. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0067] Embodiment 1, combination Figures 1 to 10 As shown, an improved structure of a floor thickness insertion measurement controller comprises an outer sleeve 1, an inner core 2 and a controller 3, wherein the inner core 2 comprises a rod body 4 and a lower end head 5, wherein the lower end head 5 is fixed to the lower end of the rod body 4, and the rod body 4 is provided with a transverse channel 6;

[0068] The outer sleeve 1 includes a cylinder 7 and a measurement control disk 8, wherein the measurement control disk 8 is fixed to the lower end of the cylinder, through holes 71 are provided at intervals on the back of the cylinder 7 along its length direction, and a vertical slide groove 9 is provided on the front of the cylinder 7 along its length direction;

[0069] The rod body 4 is placed in the inner cavity of the cylinder body 7 in a sliding manner, and the inner core 2 and the outer sleeve 1 are slidably connected;

[0070] The controller 3 passes through the vertical slide groove 9 and the transverse channel 6 and is inserted into the corresponding through hole 71 so that the controller 3 locks the relative sliding state between the inner core 2 and the outer shell 1 .

[0071] Furthermore, a line connecting the center point of the through hole 71 and the center line of the vertical slide groove 9 passes through the center of the cylinder 7 .

[0072] Furthermore, a non-slip handle cover 100 is sleeved on the upper part of the cylinder 7 .

[0073] Furthermore, a blocking block 61 is provided on the inner wall of the transverse channel 6 , and the blocking block 61 divides the transverse channel 6 into a first channel section 62 and a second channel section 63 , and the width of the second channel section 63 is smaller than that of the first channel section 62 .

[0074] Furthermore, the controller 3 includes a latch 31, a spring 32, a nut 33 and a handle 34. The head size of the latch 31 is larger than the tail size. The tail of the latch 31 passes through the through hole 71, the first channel section 62, and the second channel section 63 to extend out of the vertical slide groove 9 to connect with the nut 33. The spring 32 is sleeved on the tail of the latch 31. The spring 32 is placed in the first channel section 62. One end of the spring 32 abuts against the head of the latch 31, and the other end of the spring 32 abuts against the blocking block 61. The spring 32 constitutes a reset mechanism for the latch 31. The handle 34 and the nut 33 are fixedly connected.

[0075] Furthermore, the width of the vertical slide groove is the same as the width of the horizontal slide groove, and the width of the vertical slide groove and the width of the horizontal slide groove are both smaller than the width of the through hole.

[0076] Furthermore, a scale 421 is provided on the back of the cylinder 7 next to the through hole 71, and the scale values ​​of the scale 421 increase from top to bottom, and adjacent scale values ​​are 10 mm apart. The interval between adjacent through holes 71 is 10 mm, and the position of the scale value corresponds to the center line position of the corresponding through hole 71. In this embodiment, the marking range of the scale 421 is 60 mm-200 mm, and the outer wall of the cylinder 7 that is larger than 500 mm of the measuring control panel 8 is provided with a 500 mm scale value.

[0077] Measurement scheme (the design drawing thickness of the measured concrete floor slab A is 60 mm, and the floor slab thickness insertion measurement controller of Example 1 is used for measurement):

[0078] The design drawing thickness of the measured concrete floor A is 60mm. The user pulls the handle 34 outward to make the head of the pin 31 leave the corresponding through hole 71, so that the outer cover 1 and the inner core 2 are in a free sliding state. Then the user moves the handle 34 up and down to drive the inner core 2 to move. Since the vertical slide groove 9 limits the sliding distance of the handle 34, the moving distance of the inner core 2 is limited until the pin reaches near the 60mm scale. Then the user releases the handle 34 and moves the handle 34 up and down. When passing the 60mm scale, the pin will automatically bounce into the first through hole 71 (forming a support point for supporting the inner core 2) under the action of the spring, so that the outer cover 1 and the inner core 2 are in a locked state.

[0079] Then the user inserts the improved structure of the floor thickness dowel measurement controller into the unsolidified concrete floor A until the lower end of the lower end 5 contacts the bottom surface of the concrete floor, and then observes the measurement control panel 8:

[0080] If the bottom surface of the measuring control panel 8 is horizontally attached to the surface of the uncured concrete floor slab, the measured concrete floor slab reaches the thickness required by the design drawings.

[0081] If the surface of the unsolidified concrete slab is smaller than a certain range of the bottom surface of the measurement control panel 8, the thickness of the measured concrete slab is smaller than the thickness required by the design drawings.

[0082] If the surface of the unsolidified concrete slab is larger than a certain range of the measurement control panel 8, the thickness of the measured concrete slab is greater than the thickness required by the design drawings.

[0083] The above-mentioned thickness that is greater than or less than a certain range required by the design drawings is considered unqualified. At this time, when the workers measure a thickness that is greater than or less than the requirement of the design drawings, they can promptly adjust the thickness of the unsolidified concrete slab, and make up for the thinning and thickening, so that the thickness of the concrete slab meets the requirements of the design drawings. The improved structure of the floor slab thickness plunger measurement controller can be used for rapid measurement, and the improved structure of the floor slab thickness plunger measurement controller is suitable for measuring concrete slabs of various thicknesses, and the measurement is convenient and fast. Since the cylinder 7 is provided with a 500mm elevation, the elevation of the concrete floor slab is measured by pulling a line on the wall column steel bars (500mm elevation line above the concrete floor slab surface), thereby improving the practicability of the improved structure of the floor slab thickness plunger measurement controller.

[0084] To prevent concrete from adhering to the improved structure of the floor thickness probe measurement controller after the measurement is completed, the user can rinse it with clean water or remove the controller 3 for cleaning to facilitate next use.

[0085] Measurement scheme (the design drawing thickness of the measured concrete floor slab B is 200 mm, and the floor slab thickness insertion measurement controller of Example 1 is used for measurement):

[0086] The design drawing thickness of the measured concrete floor B is 200mm. The user pulls the handle 34 outward to make the head of the pin 31 leave the corresponding through hole 71, so that the outer cover 1 and the inner core 2 are in a free sliding state. Then the user moves the handle 34 up and down to drive the inner core 2 to move. Since the vertical slide groove 9 limits the sliding distance of the handle 34, the moving distance of the inner core 2 is limited until the pin reaches near the 200mm scale. Then the user releases the handle 34 and moves the handle 34 up and down. When passing the 200mm scale, the pin will automatically bounce into the last through hole 71 (forming a support point for supporting the inner core 2) under the action of the spring, so that the outer cover 1 and the inner core 2 are in a locked state.

[0087] Then the user inserts the improved structure of the floor thickness dowel measurement controller into the unsolidified concrete floor B until the lower end of the lower end 5 contacts the bottom surface of the concrete floor, and then observes the measurement control panel 8:

[0088] If the bottom surface of the measuring control panel 8 is horizontally attached to the surface of the uncured concrete floor slab, the measured concrete floor slab reaches the thickness required by the design drawings.

[0089] If the surface of the unsolidified concrete slab is smaller than a certain range of the bottom surface of the measurement control panel 8, the thickness of the measured concrete slab is smaller than the thickness required by the design drawings.

[0090] If the surface of the unsolidified concrete slab is larger than a certain range of the measurement control panel 8, the thickness of the measured concrete slab is greater than the thickness required by the design drawings.

[0091] The above-mentioned thickness that is greater than or less than a certain range required by the design drawings is considered unqualified. At this time, when the workers measure a thickness that is greater than or less than a certain range required by the design drawings, they can adjust the thickness of the unsolidified concrete floor slab in time, and make up for the thinning and thickening, so that the thickness of the concrete floor slab meets the requirements of the design drawings. The improved structure of the floor slab thickness plunger measurement controller can be used for rapid measurement, and the improved structure of the floor slab thickness plunger measurement controller is suitable for measuring concrete floors of various thicknesses, and the measurement is convenient and fast. Since the cylinder 7 is provided with a 500mm elevation, the elevation of the concrete floor slab is measured by pulling a line on the wall column steel bars (500mm elevation line above the concrete floor slab surface), thereby improving the practicability of the improved structure of the floor slab thickness plunger measurement controller.

[0092] To prevent concrete from adhering to the improved structure of the floor thickness probe measurement controller after the measurement is completed, the user can rinse it with clean water or remove the controller 3 for cleaning to facilitate next use.

[0093] The floor thickness dowel measurement controller of Example 1 is suitable for situations where the concrete floor is not too thick and the reaction force borne by the inner core when inserted into the concrete is not large. It only requires one supporting point to ensure that the pin and the outer sleeve are not deformed, and the user operation is more convenient.

[0094] Embodiment 2, combined Figure 11 to Figure 22 As shown, the difference between Example 2 and Example 1 is:

[0095] A vertical slide groove 9 is provided on the front side of the cylinder 7 along its length direction, and transverse slide grooves 10 are arranged at intervals on the front side of the cylinder 7 along its length direction, and the transverse slide grooves 10 are connected to the vertical slide grooves 9 .

[0096] Furthermore, the width of the transverse slide groove is the same as the width of the vertical slide groove, and the end of the transverse slide groove is a semicircular opening.

[0097] Furthermore, a line connecting the center lines of the first through hole 71 and the last through hole 71 on the back of the cylinder 7 and the center line of the vertical slide groove 9 passes through the center of the cylinder 7, and a line connecting the center lines of the remaining through holes 71 between the first through hole 71 and the last through hole 71 and the center of the semicircular opening of the horizontal slide groove 10 passes through the center of the cylinder.

[0098] Measurement scheme (the design drawing thickness of the measured concrete floor slab C is 60 mm, and the floor slab thickness insertion measurement controller of Example 2 is used for measurement):

[0099] The design drawing thickness of the measured concrete floor C is 60mm. The user pulls the handle 34 outward to make the head of the pin 31 leave the corresponding through hole 71, so that the outer cover 1 and the inner core 2 are in a free sliding state. Then the user moves the handle 34 up and down to drive the inner core 2 to move. Since the vertical slide groove 9 limits the sliding distance of the handle 34, the moving distance of the inner core 2 is limited until the pin reaches near the 60mm scale. Then the user releases the handle 34 and moves the handle 34 up and down. When passing the 60mm scale, the pin will automatically bounce into the first through hole 71 (forming a support point for supporting the inner core 2) under the action of the spring, so that the outer cover 1 and the inner core 2 are in a locked state.

[0100] Then the user inserts the improved structure of the floor thickness dowel measurement controller into the unsolidified concrete floor C until the lower end of the lower end 5 contacts the bottom surface of the concrete floor, and then observes the measurement control panel 8:

[0101] If the bottom surface of the measuring control panel 8 is horizontally attached to the surface of the uncured concrete floor slab, the measured concrete floor slab reaches the thickness required by the design drawings.

[0102] If the surface of the unsolidified concrete slab is smaller than a certain range of the bottom surface of the measurement control panel 8, the thickness of the measured concrete slab is smaller than the thickness required by the design drawings.

[0103] If the surface of the unsolidified concrete slab is larger than a certain range of the measurement control panel 8, the thickness of the measured concrete slab is greater than the thickness required by the design drawings.

[0104] The above-mentioned thickness that is greater than or less than a certain range required by the design drawings is considered unqualified. At this time, when the workers measure a thickness that is greater than or less than the requirement of the design drawings, they can promptly adjust the thickness of the unsolidified concrete slab, and make remedial measures by thinning and thickening, so that the thickness of the concrete slab meets the requirements of the design drawings. The improved structure of the floor slab thickness plunger measurement controller can be used for rapid measurement, and the improved structure of the floor slab thickness plunger measurement controller is suitable for measuring concrete slabs of various thicknesses, and the measurement is convenient and fast.

[0105] Measurement scheme (the design drawing thickness of the measured concrete floor slab D is 70 mm, and the floor slab thickness insertion measurement controller of Example 2 is used for measurement):

[0106] The design drawing thickness of the measured concrete floor D is 70mm. The user pulls the handle 34 outward to make the head of the pin 31 leave the corresponding through hole 71, so that the outer cover 1 and the inner core 2 are in a free sliding state. Then the user moves the handle 34 up and down to drive the inner core 2 to move. Since the vertical slide groove 9 limits the sliding distance of the handle 34, the moving distance of the inner core 2 is limited until the pin reaches near the 70mm scale. Then the user drives the handle 34 to move, so that the tail of the pin 31 enters the horizontal slide groove 10 (forming a support point for supporting the inner core 2). At the same time, under the action of the spring, the pin will automatically bounce into the second through hole 71 (forming a support point for supporting the inner core 2), so that the outer cover 1 and the inner core 2 are in a locked state (forming two support points in total).

[0107] Then the user inserts the improved structure of the floor thickness dowel measurement controller into the unsolidified concrete floor D until the lower end of the lower end 5 contacts the bottom surface of the concrete floor, and then observes the measurement control panel 8:

[0108] If the bottom surface of the measuring control panel 8 is horizontally attached to the surface of the uncured concrete floor slab, the measured concrete floor slab reaches the thickness required by the design drawings.

[0109] If the surface of the unsolidified concrete slab is smaller than a certain range of the bottom surface of the measurement control panel 8, the thickness of the measured concrete slab is smaller than the thickness required by the design drawings.

[0110] If the surface of the unsolidified concrete slab is larger than a certain range of the measurement control panel 8, the thickness of the measured concrete slab is greater than the thickness required by the design drawings.

[0111] The above-mentioned thickness that is greater than or less than a certain range required by the design drawings is considered unqualified. At this time, when the workers measure a thickness that is greater than or less than the requirement of the design drawings, they can promptly adjust the thickness of the unsolidified concrete slab, and make remedial measures by thinning and thickening, so that the thickness of the concrete slab meets the requirements of the design drawings.

[0113] The design drawing thickness of the measured concrete floor E is 200mm. The user pulls the handle 34 outward to make the head of the pin 31 leave the corresponding through hole 71, so that the outer sleeve 1 and the inner core 2 are in a free sliding state. Then the user moves the handle 34 up and down to drive the inner core 2 to move. Since the vertical slide groove 9 limits the sliding distance of the handle 34, the moving distance of the inner core 2 is limited until the pin reaches near the 200mm scale. Then the user releases the handle 34 and moves the handle 34 up and down. When passing the 200mm scale, the pin will automatically bounce into the last through hole 71 (forming a support point for supporting the inner core 2) under the action of the spring, and the pin will abut against the end of the vertical slide groove 9 (forming a support point for supporting the inner core 2), so that the outer sleeve 1 and the inner core 2 are in a locked state (a total of two support points are formed).

[0114] Then the user inserts the improved structure of the floor thickness dowel measurement controller into the unsolidified concrete floor E until the lower end of the lower end head 5 contacts the bottom surface of the concrete floor, and then observes the measurement control panel 8:

[0115] If the bottom surface of the measuring control panel 8 is horizontally attached to the surface of the uncured concrete floor slab, the measured concrete floor slab reaches the thickness required by the design drawings.

[0116] If the surface of the unsolidified concrete slab is smaller than a certain range of the bottom surface of the measurement control panel 8, the thickness of the measured concrete slab is smaller than the thickness required by the design drawings.

[0117] If the surface of the unsolidified concrete slab is larger than a certain range of the measurement control panel 8, the thickness of the measured concrete slab is greater than the thickness required by the design drawings.

[0118] The above-mentioned thickness that is greater than or less than a certain range required by the design drawings is considered unqualified. At this time, when the workers measure a thickness that is greater than or less than the requirement of the design drawings, they can promptly adjust the thickness of the unsolidified concrete slab, and make remedial measures by thinning and thickening, so that the thickness of the concrete slab meets the requirements of the design drawings.

[0119] Embodiment 2 is suitable for the case where the concrete floor is thicker. The reaction force borne by the inner core when inserted into the concrete is larger. The two-support point solution can more easily ensure that the pin and the outer tube are not easily deformed. Therefore, the floor thickness insertion measurement controller (two support points) of Embodiment 2 can measure thicker concrete floors than the floor thickness insertion measurement controller (one support point) of Embodiment 1. For example, Embodiment 2 can measure concrete floors with a thickness greater than 200 mm.

[0120] In the above-mentioned Embodiment 1 and Embodiment 2, after the concrete floor thickness measurement is completed, the user can clean the improved structure of the floor thickness probe measurement controller with clean water to prevent the improved structure of the floor thickness probe measurement controller from being stuck with concrete, so as to facilitate the next use.

[0121] The outer sleeve 1 in the above-mentioned embodiment 1 and embodiment 2 is a circular tube. In other embodiments, the outer sleeve 1 may also be a cylindrical structure such as a square or polygonal structure.

[0122] The inner core 2 in the above-mentioned embodiment 1 and embodiment 2 is a round tube. In other embodiments, the cylinder body may also be a square or polygonal cylinder body structure, as long as the inner core 2 can slide freely in the outer sleeve 1.

[0123] The lower end of the lower end head 5 of the above-mentioned embodiment 1 and embodiment 2 is pointed (such as Fig.24 As shown in FIG. 1 ), in other embodiments, the lower end 5 can also be designed to be semicircular (as shown in FIG. Fig.23 As shown) and round, and the lower end 5 can be made of alloy steel material and have a pointed shape (such as Fig.25 As shown), the wear resistance of the lower end head 5 is enhanced.

[0124] When used to measure the thickness of road concrete (the base layer below the road concrete surface layer is a soil or gravel base layer), the lower end of the lower end head is semicircular to prevent the lower end of the lower end head from being inserted into the gravel or soil base layer, thereby improving the measurement accuracy.

[0125] The thickness range measured by the floor thickness plunger measurement controller in the above-mentioned embodiments 1 and 2 is 60mm-200mm. In other embodiments, the thickness range measured by the floor thickness plunger measurement controller can be adjusted according to actual needs. For example, the thickness range measured by the floor thickness plunger measurement controller is 50mm-200mm, 60mm-300mm, 60mm-350mm, etc.
