Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering, and in particular relates to a concrete component thickness detection device. Background Art

[0002] Because concrete structural components have the characteristics of good structural performance, fast construction speed, good product quality, and good fire resistance, they are frequently used in the field of construction engineering. In order to ensure the qualification of concrete components, a thickness detection device is needed to detect the thickness of concrete components.

[0003] The Chinese patent with publication number CN219121317U discloses a device for detecting the thickness of concrete structural members of a construction project, comprising a fixed box and two side panels, the two side panels are symmetrically fixedly installed on the left and right sides of the fixed box, and an electric push rod is vertically fixedly installed on the inner top, a hole is penetrated at the midpoint position of the lower end of the fixed box, the electric push rod passes through the hole, and a measuring plate is horizontally fixedly installed on the lower end of the electric push rod, a scale is vertically arranged on the inner side wall of the side panel, and infrared transmitters are arranged on both sides of the measuring plate near the side panel. The above scheme drives the measuring plate to move up and down horizontally through the setting of the electric push rod, moves the measuring plate to the upper end of the object to be measured, and then measures the height difference from the lower end of the measuring plate to the lower end of the object to be measured to obtain the thickness of the object, and through the setting of the infrared transmitter, in combination with the scale, the measured value can be quickly read, and the entire device can realize rapid and accurate detection of the thickness of concrete structural members of a construction project.

[0004] However, in actual use, although the scale value corresponding to the lower surface of the measuring plate can be identified by the infrared transmitter, since the scale is located on the inner side of the side panel, the side panel and the fixing box have a certain obstruction effect on the light. Therefore, when observing the scale, the surveyor needs to constantly adjust the light receiving angle on the inner side of the side panel of the device to clearly distinguish the reading on the scale. That is, the above scheme is not convenient for reading the test results. Utility Model Content

[0005] The utility model aims to provide a device for detecting the thickness of a concrete component, so as to solve the problem that the above-mentioned solution is inconvenient to read the detection result.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for detecting the thickness of a concrete member, comprising:

[0007] Fixed box;

[0008] Side panels, two side panels are provided and symmetrically installed at the lower end of the fixed box, the inner wall of the side panel is provided with a sliding groove, a guide rod is fixed in the sliding groove, the outer wall of the side panel is provided with an observation groove connected with the sliding groove, and the outer wall of the side panel is provided with a scale near the observation groove;

[0009] The measuring plate group is slidably matched with the guide rod, and the measuring plate group slides in the sliding groove. The side wall of the measuring plate group is fixed with an identification plate, the identification plate is slidably matched with the observation groove, and the bottom surface of the identification plate is flush with the bottom surface of the measuring plate group. A spring is sleeved on the guide rod, and the spring is located between the measuring plate group and the fixed box.

[0010] The principle and effect of this technical solution:

[0011] 1. After holding the fixing box and placing the side plate and the concrete component to be measured on the same horizontal plane, the projection of the concrete component on the side plate is the thickness of the concrete component, and the measuring plate group slides in the sliding groove and cooperates with the guide rod, and the identification plate is fixed to the measuring plate group, and the lower surface of the identification plate is flush with the lower surface of the measuring plate group. Therefore, by putting the measuring plate on the upper surface of the concrete component and making the bottom of the side plate contact with the horizontal plane, the distance from the lower surface of the identification plate to the bottom of the side plate is the thickness of the concrete component. The identification plate slides in the observation groove, and the outer end of the observation groove is also provided with a scale. Therefore, the inspector can obtain the thickness of the concrete component through the scale value corresponding to the identification plate on the outer surface of the side plate, and the scale mark is on the outer side of the side plate without light obstruction, which is conducive to the reading of the test result data.

[0012] 2. By setting the spring, measuring plate group, guide rod and sliding groove, the position of the measuring plate group can be adaptively adjusted according to the thickness of the concrete member, so that there is no need for manual adjustment or electric drive to adjust the position of the measuring plate group. That is, when measuring, the surveyor places the side plates on both sides of the concrete member, and then abuts the measuring plate group against the surface of the concrete member, and then presses down with the grip of the fixed box to make the side plate abut against the horizontal plane. The measuring plate group cannot be pressed down due to the limitation of the concrete member, thereby compressing the spring. The compression of the spring makes the measuring plate group slide relative to the side plate. Therefore, the position of the measuring plate group can be automatically adjusted according to the thickness of the concrete member, which saves manpower.

[0013] The utility model is further configured as follows: the measuring plate group includes a detection plate, a connecting plate and a movable plate, two connecting plates are provided and are symmetrically arranged on both sides of the detection plate, two movable plates are provided and are slidably plugged with the connecting plates on both sides respectively, the movable plates on both sides slide in the sliding grooves on both sides respectively, and are slidably matched with the guide rods on both sides respectively, the identification plate is fixed to the movable plate, and the lower surface of the identification plate, the lower surface of the detection plate and the lower surface of the movable plate are all in the same horizontal plane.

[0014] The principle and effect of this technical solution: through the sliding connection between the connecting plate and the movable plate, the movable plate can move left and right relative to the connecting plate, that is, the overall width of the measuring plate can be adjusted according to the spacing between the side plates, thereby making the measuring plate group more applicable.

[0015] The utility model is further configured as follows: a telescopic rod is fixed on the side plate, the upper end of the telescopic rod passes through the bottom of the fixed box and is fixed to the top of the inner wall of the fixed box, and the thread on the side wall of the telescopic rod is matched with a limiting bolt.

[0016] The principle and effect of this technical solution: the setting of the telescopic rod makes the position of the detection plate moderately located in the center of the movable plates on both sides, so that the connecting plate will not be separated from the movable plate, and at the same time the force between the movable plate and the connecting plate is more balanced. The setting of the limit bolt makes it inconvenient for workers to press and observe at the same time. The telescopic rod can be limited by the limit bolt to prevent the spring from driving the movable plate to reset, so that workers can choose the observation method according to their needs.

[0017] The utility model is further configured as follows: a bidirectional screw is rotatably connected in the fixed box, one end of the bidirectional screw passes through the side wall of the fixed box and is fixed with a screw cap, the thread on the bidirectional screw is matched with a nut seat, a clearance groove is opened at the lower end of the fixed box, the lower end of the nut seat is slidably matched with the clearance groove, and the side plate is fixed to the bottom of the nut seat.

[0018] The principle and effect of this technical solution: the bidirectional screw is driven by the screw cap, so that the bidirectional screw can drive the nut seat to move, thereby driving the side plate to move, so that the distance between the side plates on both sides can be adjusted according to the width of the concrete member, and in this process, in order to cooperate with the change of the distance between the side plates, the matching length between the connecting plate and the movable plate is also changed, so that the distance adjustment between the side plates can operate normally.

[0019] The utility model is further configured as follows: a measuring groove is opened on the fixed box, a scale is formed on the upper surface of the fixed box near the measuring groove, a measuring plate is fixed on the upper end of the nut seat, and the measuring plate is slidably matched with the measuring groove.

[0020] The principle and effect of the technical solution are as follows: by setting the measuring plate, the measuring groove and the scale, the spacing between the side plates on both sides can be adjusted according to the width of the concrete component, and the side plates on both sides can be clamped with the concrete component, and then the width of the concrete component is obtained according to the reading difference of the measuring plate, so that the device can not only measure the thickness of the concrete component, but also measure the width or length of the concrete component, making the use function of the device more extensive and comprehensive, and improving the scope of application of the device.

[0021] The utility model is further configured that: the inner wall of the measuring plate, the inner wall of the nut seat and the inner wall of the side plate on the same side are in the same vertical plane.

[0022] The principle and effect of this technical solution: Because the inner wall of the measuring plate, the inner wall of the nut seat and the inner wall of the side plate are in the same vertical plane, the distance between the inner walls of the measuring plates on both sides is the width of the concrete component, making it easier for inspectors to read the width of the concrete component.

[0023] The utility model is further configured as follows: the handle on the fixed box is provided with anti-skid patterns.

[0024] The principle and effect of this technical solution: The setting of the anti-slip texture allows the surveyor to hold the handle of the fixed box tightly, so as to better apply force. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] As attached Figure 1-5 As shown, the utility model discloses a concrete member thickness detection device, including a fixing box 101, a side plate 201 and a measuring plate group;

[0033] A handle is provided on the top of the fixed box 101, and anti-skid lines are formed on the handle. A bidirectional screw 401 is rotatably connected in the fixed box 101. The bidirectional screw 401 is arranged in the left and right directions. The left end of the bidirectional screw 401 passes through the side wall of the fixed box 101 and is fixed with a screw cap 402. Two nut seats 403 are threadedly matched on the bidirectional screw 401. The two nut seats 403 are symmetrically arranged about the bidirectional screw 401. A clearance groove 102 is provided at the lower end of the fixed box 101, and the lower end of the nut seat 403 is slidably matched with the clearance groove 102. A measuring groove 103 is provided at the upper end of the fixed box 101, and a scale is formed on the upper surface of the fixed box 101 near the measuring groove 103. A measuring plate 404 is fixed to the upper end of the nut seat 403, and the measuring plate 404 is slidably matched with the measuring groove 103.

[0034] Two side panels 201 are provided and are respectively fixed at the bottom of two nut seats 403. A vertical sliding groove 202 is provided on the inner wall of the side panel 201. A vertically arranged guide rod 203 is fixed in the sliding groove 202. A spring 205 is sleeved on the guide rod 203. An observation groove 204 connected to the sliding groove 202 is provided on the outer wall of the side panel 201. A scale is formed on the outer wall of the side panel 201 near the observation groove 204. The spring 205 is in a compressed state when not in operation.

[0035] The measuring plate group includes a detection plate 301, a connecting plate 302 and a movable plate 303. Two connecting plates 302 are provided and are symmetrically arranged on both sides of the detection plate 301. Two movable plates 303 are provided and are slidably plugged with the connecting plates 302 on both sides respectively. The movable plates 303 slide in the sliding grooves 202 on both sides respectively, and are slidably matched with the guide rods 203 on both sides respectively. Identification plates 306 are fixed to the outer sides of the movable plates 303 on both sides. The identification plates 306 are slidably matched with the observation grooves 204. The lower surface of the identification plate 306, the lower surface of the detection plate 301 and the lower surface of the movable plate 303 are all in the same horizontal plane, and the inner wall of the measuring plate 404, the inner wall of the nut seat 403 and the inner wall of the side plate 201 on the same side are in the same vertical plane.

[0036] Telescopic rods 304 are fixed to the front and rear ends of the upper surface of the side panel 201. The upper end of the telescopic rod 304 passes through the bottom of the fixed box 101 and is fixed to the top of the inner wall of the fixed box 101. The thread on the side wall of the telescopic rod 304 is engaged with a limiting bolt 305. The threaded end of the limiting screw passes through the side wall of the fixed end of the telescopic rod 304 and abuts against the outer wall of the sliding end of the telescopic rod 304.

[0037] The specific implementation process is as follows:

[0038] When the device is used to inspect a concrete member, the device is first held and placed on the upper surface of the concrete member. The screw cap 402 is then rotated according to the width of the concrete member, so that the screw cap 402 drives the bidirectional screw 401 to rotate so that the spacing between the two side plates 201 is wider than the width of the concrete member. The inspector then holds the handle to allow the inspection plate 301 and the movable plate 303 to abut against the upper surface of the concrete member, and then presses the handle downward. The downward pressure drives the side plate 201 to overcome the elastic force of the spring 205 and move downward, while the inspection plate 301 and the movable plate 303 are limited by the upper surface of the concrete member and stop moving. At this time, the identification plate 306 is relative to the side plate 201. And the observation groove 204 slides. When the side plate 201 abuts against the horizontal plane, the scale corresponding to the identification plate 306 is the thickness value of the concrete component. The inspector can press the handle with one hand and lean sideways to observe the scale value corresponding to the identification plate 306. If the inspector is unable to lean sideways to observe due to position restrictions, he can press the handle with one hand and use the other hand to screw the limit bolt 305 on the telescopic rod 304 so that the limit bolt 305 is tightly against the outer wall of the movable rod of the telescopic rod 304. The device can then be taken out to observe and record the readings at a suitable position. The scale value is made on the outside of the side plate 201 and will not be blocked by other devices, so it is easy for the inspector to observe.

[0039] While inspecting the concrete component, the inspector can also turn the screw cap 402 to make the side plates 201 on both sides close to the concrete component. After the side plates 201 on both sides clamp the concrete component, the inspector can read the width of the concrete component through the scale difference corresponding to the measuring plates 404 on both sides, so that the device can detect two data on the concrete component in one inspection process, thereby improving the scope of application of the device.
