[0023] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0024] The present application provides a detection tool for post-cast strip construction.

[0025] First embodiment:

[0026] Please refer to Figures 1 to 3 In the first embodiment of the present application, the detection tool for post-cast strip construction comprises: A fixed ruler plate 1 is provided with a first scale bar 11 integrated thereon, and a first measuring plate 12 is fixedly arranged on the top of the fixed ruler plate 1; An active ruler plate 2 is slidingly installed on the fixed ruler plate 1, the fixed ruler plate 1 is located between the active ruler plate 2 and the first scale bar 11, a second scale bar 21 is integrated on the active ruler plate 2, and a second measuring plate 22 is fixedly arranged on the bottom of the active ruler plate 2; An angle ruler plate 3 is fixedly arranged on the fixed ruler plate 1, and a pointer 31 is rotatably installed on the angle ruler plate 3; A synchronous mechanism 4 comprises a support foot 41 and a transmission member 42, the support foot 41 is rotatably installed on the bottom of the fixed ruler plate 1, the transmission member 42 is in transmission connection with the support foot 41 and the pointer 31, and the support foot 41 and the pointer 31 are distributed in parallel; When the bottom of the second measuring plate 22 is aligned with the bottom of the support foot 41, the top of the active ruler plate 2 protrudes relative to the fixed ruler plate 1, and the protruding distance is equal to the thickness of the second measuring plate 22.

[0027] When measurement is needed, the second measuring plate 22 and the active ruler plate 2 can be pulled upward relative to the support foot 41 to reserve an active space for the measurement of the support foot 41. When the support foot 41 is vertically distributed relative to the fixed ruler plate 1, the pointer 31 is indicated at 90° of the angle ruler plate 3.

[0028] Preferably, the zero scale of the first scale bar 11 corresponds to the inner side of the first measuring plate 12 (in the direction of the arrow A in the drawing). Figure 1The bottom surface of the first measuring plate 12 is the inner surface. The zero mark of the second scale bar 21 is located at the top of the movable ruler plate 2.

[0029] Please refer to the following: Figure 1 and Figure 4 The principle of measuring the concrete cover of reinforcing bars: When measuring the installation angle of the main reinforcement structure, first attach the fixed ruler plate 1 to the surface of the main reinforcement structure, and then push the support bracket 41 downward so that the bottom of the fixed ruler plate 1 is supported on the ground by the support bracket 41. The angle between the fixed ruler plate 1 and the support bracket 41 is the same as the angle indicated by the pointer 31 on the angle ruler plate 3, so that the installation angle of the main reinforcement structure can be quickly measured by using the corresponding degree on the angle ruler plate 3 by the pointer 31.

[0030] Manually pull the movable ruler 2 upwards. The movable ruler 2 causes the second measuring plate 22 to move upwards relative to the fixed ruler 1. The second measuring plate 22 moves upwards and abuts against the bottom of the measuring steel bar. At this time, the reading on the fixed ruler 1 relative to the second scale bar 21 is the thickness of the bottom protective layer of the steel bar, thereby realizing the rapid measurement of the thickness of the bottom protective layer of the steel bar.

[0031] When measuring the spacing of the main reinforcement bars, the fixed ruler 1 is first placed horizontally on the top of the reinforcement structure. The first measuring plate 12 is abutted against one main reinforcement bar. By pulling the movable ruler 2, the second measuring plate 22 is controlled to abut against another main reinforcement bar, so that the first measuring plate 12 and the second measuring plate 22 are clamped on the two main reinforcement bars. The installation spacing between the two main reinforcement bars is quickly read by the reading of the second measuring plate 22 corresponding to the first scale bar 11, which facilitates the rapid measurement of the spacing of the main reinforcement bars of the reinforcement structure. It enables rapid measurement of the bottom protective layer of reinforcing bars, and simultaneously measures the installation angle of the reinforcing bars; after completing the measurement of the bottom protective layer, it can also measure the spacing of the main reinforcing bars of the reinforcing bar structure.

[0032] In one embodiment, the transmission component 42 includes two transmission wheels and a transmission belt. The transmission belt drives the two transmission wheels. One transmission wheel is fixedly connected to the rotating shaft of the pointer 31, and the other transmission wheel is fixedly connected to the rotating part of the support bracket 41.

[0033] A stable connection is achieved between the support bracket 41 and the pointer 31, so that when the support bracket 41 rotates relative to the fixed ruler plate 1, the pointer 31 rotates synchronously with the position indicated on the angle ruler plate 3, thereby facilitating and intuitive observation of the installation angle of the steel bar relative to the ground.

[0034] In another embodiment, the transmission component 42 includes two sprockets and a chain, the chain drivingly connecting the two sprockets, one sprocket being fixedly connected to the rotating shaft of the pointer 31, and the other sprocket being fixedly connected to the rotating part of the support bracket 41.

[0035] Please refer to the following: Figure 3 and Figure 2 Dissect the relevant structures, along Figure 2 Viewed from above in a vertical direction, the fixed ruler plate 1 has an adjustment cavity 101, and the rotating shaft of the pointer 31 passes through the fixed ruler plate 1 and is inserted into the range of the adjustment cavity 101; The inspection tool for post-pouring strip construction also includes a torsion spring 5. The two ends of the torsion spring 5 are fixedly connected to the rotating shaft of the pointer 31 and the fixed ruler plate 1. The movable ruler plate 2 is slidably mounted on the fixed ruler plate 1 via a limiting slider 6. A limiting groove 201 is provided on the movable ruler plate 2. One end of the limiting slider 6 is inserted into the limiting groove 201 and slidably connected to the movable ruler plate 2. The other end of the limiting slider 6 is mounted on the fixed ruler plate 1.

[0036] A torsion spring 5 is added to the rotating shaft of the pointer 31 to keep the pointer 31 at 90° on the angle ruler 3 without external force, so as to adaptively control the pointer 31 to reset after measurement, thereby facilitating the measurement of whether the installation angle of the reinforcing bar meets the design standard.

[0037] In this embodiment, the other end of the limiting slider 6 is fixedly installed on the fixed ruler plate 1.

[0038] Please refer to the following: Figure 1 and Figure 4 Before installing the 200mm formwork, measure the bottom protective layer of the reinforcing bars: Step A1: Place the bottom of the support frame 41 against the ground, and insert the second measuring plate 22 into the bottom of the reinforcing bar (main bar or tie bar); Step A2: Place the surface of the fixed ruler plate 1 against the surfaces of the two corresponding steel bars, with the bottom of the support bracket 41 abutting against the ground. Observe the position of the pointer 31 corresponding to the angle ruler plate 3, and quickly measure and read the angle of the steel bars relative to the ground after installation. Step A3: Manually pull the movable ruler 2 upwards. The movable ruler 2 drives the second scale bar 21 and the second measuring plate 22 to move upwards. After the second measuring plate 22 moves upwards, it completely abuts against the bottom of the steel bar. Observe the position of the fixed ruler 1 relative to the second scale bar 21 and quickly measure and read the thickness of the protective layer at the bottom of the steel bar. Step A4, push the movable ruler plate 2 down and fully nest on the fixed ruler plate 1, reset the device, move the fixed ruler plate 1 to another measuring point, repeat steps A1 to A3; Step A5, after the measurement of the reinforcement bottom protection layer is completed, first place the fixed ruler plate 1 horizontally on the top of the reinforcement structure, control the first measuring plate 12 to abut on a main reinforcement, pull out the movable ruler plate 2 to control the second measuring plate 22 to abut on another main reinforcement, so that the first measuring plate 12 and the second measuring plate 22 are clamped on the two main reinforcements, and the installation spacing between the two adjacent main reinforcements is measured. Step A6, as Figure 9 (b), after the measurement of the spacing between the adjacent main reinforcements is completed, the formwork 200 is installed and fixed, first place the fixed ruler plate 1 horizontally on the top of the main reinforcement structure, control the first measuring plate 12 to abut on a formwork 200, pull out the movable ruler plate 2 to control the second measuring plate 22 to abut on another formwork 200, so that the first measuring plate 12 and the second measuring plate 22 are clamped on the two formworks 200, and the installation spacing between the two adjacent formworks 200 is measured.

[0039] Second embodiment:

[0040] Please refer to Figures 5 to 6 , based on the first embodiment of the present application, another detection tool for post-cast strip construction is provided. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0041] Specifically, the detection tool for post-cast strip construction provided by the second embodiment of the present application is different in that the other end of the limiting sliding block 6 is rotatably installed on the fixed ruler plate 1 through a rotating shaft 61.

[0042] That is, one end of the rotating shaft 61 is fixedly connected with the limiting sliding block 6, and the other end of the rotating shaft 61 is rotatably connected with the fixed ruler plate 1.

[0043] The movable ruler plate 2 includes two use modes: As Figure 1 and Figure 9 (a) shown, the reinforcement bottom protection layer measurement mode, the movable ruler plate 2 maintains parallel distribution with the fixed ruler plate 1, in use, the bottom of the fixed ruler plate 1 abuts on the ground of the measurement area, the bottom of the second measuring plate 22 faces the ground for measurement, so as to measure the thickness of the reinforcement bottom protection layer.

[0044] As Figure 8 (b) and Figure 9(c) as shown, the reinforcing steel bar top protection layer measurement mode, the movable ruler plate 2 maintains the vertical distribution with the fixed ruler plate 1, when used, the fixed ruler plate 1 is horizontally arranged above the formwork 200, the bottom of the second measurement plate 22 is aligned in the measurement area of the reinforcing steel bar, so as to measure the thickness of the protection layer on the top of the reinforcing steel bar.

[0045] The measurement principle of the reinforcing steel bar top protection layer is that after the installation interval measurement of the formwork 200 is completed, the use mode of the movable ruler plate 2 is adjusted to the reinforcing steel bar top protection layer measurement mode, the fixed ruler plate 1 is horizontally placed on the top of the formwork 200, the lifting adjustment of the movable ruler plate 2 is controlled, so that the bottom of the second measurement plate 22 abuts on the main reinforcing steel bar to be measured, the first measurement value is obtained by reading the position of the bottom of the fixed ruler plate 1 on the second scale bar 21, the maximum length of the second scale bar 21 is subtracted from the first measurement value, and the thickness of the reinforcing steel bar top protection layer is obtained, and the reinforcing steel bar top protection layer of multiple points is measured in turn.

[0046] The movable ruler plate 2 is rotatably installed on the fixed ruler plate 1 through the limiting sliding block 6 and the rotating shaft 61, so as to manually adjust the rotation of the movable ruler plate 2 relative to the fixed ruler plate 1, thereby manually switching the use mode of the movable ruler plate 2.

[0047] The movable ruler plate 2 can not only be telescopically adjusted relative to the fixed ruler plate 1, but also be rotationally adjusted relative to the fixed ruler plate 1, so as to switch the use mode, and can be applied not only to the measurement of the reinforcing steel bar bottom protection layer, but also to the measurement of the reinforcing steel bar top protection layer.

[0048] Please refer to Figure 5 and Figure 6 The post-cast strip construction detection tool further comprises a locking mechanism 7, the locking mechanism 7 comprises a rotating disc 71, a movable plate 72 and an adjusting piece 73, the rotating shaft 61 penetrates the fixed ruler plate 1 and is inserted into the range of the adjusting cavity 101, the rotating disc 71 is fixedly arranged on the rotating shaft 61, four clamping grooves 711 are formed in the rotating disc 71, the movable plate 72 is slidingly installed in the adjusting cavity 101, the two ends of the adjusting piece 73 are fixedly connected with the fixed ruler plate 1 and the movable plate 72, a clamping block 721 is fixedly arranged on the movable plate 72, the clamping block 721 is inserted into the clamping groove 711 and is limited in position by clamping with the rotating disc 71.

[0049] The adjusting piece 73 is convenient to drive the movable plate 72 to telescopically adjust, and is used for unlocking or locking the mode of the movable ruler plate 2.

[0050] When the movable plate 72 is retracted, the clamping block 721 is inserted into the clamping groove 711 and clamped with the rotating disc 71, so as to lock the movable ruler 2 in the corresponding use mode; When the movable plate 72 is extended, the clamping block 721 is separated from the clamping groove 711 and separated from the rotating disc 71, so as to switch the mode of the movable ruler 2.

[0051] After the movable ruler 2 is unlocked relative to the fixed ruler 1, the use mode of the movable ruler 2 is conveniently manually switched; after the movable ruler 2 is locked relative to the fixed ruler 1, the use mode of the movable ruler 2 is conveniently locked and positioned, and the stability of the movable ruler 2 in the corresponding use mode is ensured.

[0052] In an optional embodiment of the embodiment, the adjusting member 73 can be an electric telescopic rod for directly driving the movable plate 72 to move and adjust.
