[0025] The application will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, but not to limit the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for the convenience of description.

[0026] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0027] Referring to Figures 1 to 5 The present application provides an irregular thickness measuring device for construction site, which comprises a test frame 1 and a point measuring assembly 2. The number of the point measuring assembly is one or two.

[0028] Specifically, in one embodiment, the number of the point measuring assembly is one. The test frame 1 of the irregular thickness measuring device for construction site according to the present application comprises an upper beam 12, a lower beam 11 and a connecting column 13.

[0029] The upper beam 12 and the lower beam 11 are arranged in the same direction. The connecting column 13 is connected between one end of the upper beam 12 and one end of the lower beam 11. A plurality of guide holes are formed on the side of the upper beam 12 facing the lower beam 11.

[0030] The point measuring assembly 2 comprises a plurality of impact pins 21, a shutter plate 22, a movable member 23, a pull rod 24 and a locking member 25.

[0031] Specifically, the striker 21 has opposite abutting end and a sliding end. The sliding end of each striker 21 is elastically mounted in a guide hole. The bottom of the guide hole and the sliding end of the rotor are connected by a spring. The abutting end of the striker 21 extends to the outside of the guide hole. The abutting end of the striker 21 is mounted with a displacement sensor. The displacement sensor is used to collect the distance between the end face of the abutting end of the striker 21 and the bottom surface of the upper beam. In this embodiment, the cross section of the upper beam and the lower beam is rectangular respectively. The bottom surface of the upper beam is opposite to the top surface of the lower beam.

[0032] The gate plate 22 is supported on the abutting end of the plurality of strikers 21. This is the initial position of the striker, and the spring is in a compressed state. The gate plate 22 and the lower beam 11 form a containing space for containing the object to be measured. When measuring the thickness of the object to be measured, the object to be measured is placed on the top surface of the lower beam, and when the gate plate releases the striker, the striker extends downward and abuts against the upper surface of the object to be measured.

[0033] The upper beam 12 is provided with a vertical hole at each end. The movable member 23 is movably contained in the vertical hole. The two ends of the gate plate 22 are connected to the movable members 23 at the two ends of the upper beam 12 through the pull rod 24. The bottom of the vertical hole is provided with a locking member 25 for locking the movable member 23. The hole diameter of the vertical hole is larger than the outer diameter of the pull rod. The movable member, on the one hand, is slidably arranged in the vertical hole, and on the other hand, can be rotated in the vertical hole. Therefore, the pull rod, on the one hand, can move along the axial direction of the vertical hole, and on the other hand, when the movable member slides to the hole opening position of the vertical hole, the pull rod can also be flipped upward by a predetermined angle (the flip angle is small, and it is appropriate for the gate plate to be separated from the striker and the object to be measured). In order to improve the flip angle range of the pull rod, the upper beam is provided with a flip groove connected to the vertical hole, and after the movable member is flipped upward, the pull rod can be embedded in the flip groove and continue to flip upward by a larger angle.

[0034] When measuring the object to be measured with irregular thickness, the object to be measured is inserted into the containing space between the gate plate and the lower beam, so that the object to be measured is placed on the top surface of the lower beam. After the object to be measured is inserted into the containing space, the locking member 25 releases the locking of the movable member 23, the abutting end pushes the gate plate 22 downward to make the movable member 23 slide to the hole opening of the vertical hole, and then the movable member 23 is flipped upward to make the gate plate 22 be separated from the abutting end and the object to be measured, so that the plurality of abutting ends abut against the object to be measured.

[0035] After the end face of the abutting end of the plurality of strikers abuts against the upper surface of the object to be measured, the displacement sensor collects the first distance value between the end face of the abutting end of the striker and the bottom surface of the upper beam. The second distance value between the bottom surface of the upper beam and the top surface of the lower beam can be regarded as known by measurement. By calculating the difference between the second distance value and the first distance value, the difference is the thickness of the point of the object to be measured.

[0036] The irregular thickness measuring device for construction site of the present application can quickly and accurately measure the thickness of the uneven thickness object at multiple points (positions) at the same time, which improves the construction efficiency, saves labor and shortens the construction period.

[0037] In the present embodiment, the upper beam 12 is provided with a plurality of display screens 26. The positions of the plurality of display screens correspond to the positions of the plurality of firing pins one by one. The plurality of display screens 26 are connected to the displacement sensors at the abutting ends of the plurality of firing pins 21 one by one.

[0038] In some embodiments, the display screen is connected to the displacement sensor through a controller. The controller acquires the first distance value collected by the displacement sensor in real time, calculates the difference value based on the preset second distance value, and outputs the difference value on the display screen. The construction personnel can quickly and intuitively know the detailed thickness of the uneven thickness object at different positions, which improves the construction quality.

[0039] Referring to Figure 4 and Figure 5 , in the present embodiment, the upper beam 12 is provided with a through hole communicating with the upper part of the vertical hole. The locking member 25 is detachably inserted into the through hole and extends to the upper part of the vertical hole to support the movable member 23, thereby locking the movable member at the bottom position of the vertical hole. After the locking member 25 is withdrawn into the through hole, the locking member 25 releases the locking of the movable member 23, and then the movable member slides to the opening position of the vertical hole after the firing pin pushes the gate.

[0040] Continuing to refer to Figure 4 and Figure 5 , the inner wall of the vertical hole is oppositely formed with a guide groove. The opposite sides of the movable member 23 are formed with sharp ends. The sharp ends of the movable member are rotatably slidably arranged in the guide groove. The guide groove is arranged in the axial direction of the vertical hole and extends to the opening of the vertical hole.

[0041] In the present embodiment, the movable member 23 is spindle-shaped.

[0042] Referring to Figure 2 and Figure 3 , as a preferred embodiment, when the upper surface and the lower surface of the object to be measured are both uneven surfaces, the side of the lower beam 11 facing the upper beam 12 is provided with another point measuring assembly 2. The gate 22 of the two-point measuring assembly 2 forms a receiving space.

[0043] Correspondingly, the lower beam is provided with a vertical hole and a guide hole, which will be described in detail with reference to the structure of the upper beam.

[0044] The present application provides a measuring method for an irregular thickness measuring device for a construction site, comprising the following steps:

[0045] S1: inserting the object to be measured into the receiving space.

[0046] In the embodiment, one side of the object to be measured is a flat surface and the other side is an uneven surface. The flat surface of the object to be measured is placed against the top surface of the lower beam, so that the uneven surface of the object to be measured faces the gate.

[0047] S2: The locking member 25 releases the locking of the movable member 23, and pushes the abutting end downward to push the gate 22, so that the movable member 23 slides to the opening of the vertical hole, and the gate 22 is pressed against the side of the object to be measured away from the lower beam 11.

[0048] S3: The movable member 23 is turned upward, and the gate 22 is pulled out from between the abutting end and the object to be measured, so that the plurality of abutting ends abut against the side of the object to be measured away from the lower beam 11.

[0049] S4: The displacement sensor on the plurality of plungers 21 collects the first distance value of the abutting end to the bottom of the upper beam 12, and the distance value between the upper beam 12 and the lower beam 11 is the second distance value, so that the thickness of a part of the object to be measured is the difference between the second distance value and the first distance value.

[0050] In some embodiments, when the opposite two sides of the object to be measured are uneven surfaces, the number of measuring plungers of the point measuring assembly is two. When the irregular thickness of the object to be measured is obtained, the first distance value obtained by the two point measuring assemblies is subtracted from the second distance value, and the difference is the thickness of the irregular thickness of the object to be measured.

[0051] The above description is only the preferred embodiment of the present application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the application involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features disclosed in the present application (but not limited to) having similar functions to form technical solutions.
