[0002] Before using steel bars, it is necessary to check the bending angle of the steel bars and the straight section of the steel bar hook to ensure that they meet the construction specifications. Therefore, a professional inspection tool is needed. After searching, the patent with authorization announcement number CN102353315B discloses a special inspection tool for stirrup hooks and its application method. The tool is in the shape of a symmetrical ruler with a flat surface and two long sides. The angle a between the two long sides is an arc shape, and a is 45°. When in use, put the tool in the stirrup and observe whether the stirrup fits with it to determine whether the bending angle and the straight length meet the requirements. The device also has the following technical problems when in use: (1) When in use, the length of the long side L of the tool is observed to check whether it is equal to the length of the stirrup hook to make a judgment. That is to say, the length of the long side of the tool is a fixed value, but different construction requirements also have different design requirements for the length of the straight section of the hook. Therefore, its use has limitations and cannot meet the use requirements of various working conditions; (3) Since angle a is a specific angle value, only the corresponding steel bar hook can be checked, and the angle of the steel bar hook corresponds to multiple values ​​of 45°, 90°, 135° and 180°. Therefore, the above device has limitations when in use.

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] like Figure 1-11 As shown, this embodiment proposes a combined steel bar bend hook inspection tool, including a scale plate 1, the scale plate 1 is circular, and the scale plate 1 is provided with a notch 12, the notch 12 is a 90° right-angle notch, and a plug-in sleeve 2 is correspondingly arranged at the notch 12, the plug-in sleeve 2 is fixedly connected to the scale plate 1, and the fixed connection method can be gluing or spot welding; the seam at the vertical connection between the plug-in sleeve 2 and the scale plate 1 forms an identification line. Since the plug-in sleeve 2 and the scale plate 1 are connected to form a seam, the seam can be used as an obvious identification line. When inspecting a straight section, the identification line can be used to better play a positioning role.

[0039] The plug-in sleeve 2 is a rectangular structure with a through plug-in port 21, and a ruler 3 is detachably inserted in the plug-in sleeve 2; the adopted rectangular structure can be conveniently matched with the ruler 3, and at the same time, the rectangular structure increases the plug-in area and can better provide plug-in stability; one end of the ruler 3 is positioned at the marking line. When in use, the zero scale segment of the ruler 3 is inserted into the plug-in sleeve 2 and rests on the inner wall of the notch 12 of the dial. At this time, the zero scale line is aligned with the marking line, which is convenient for positioning.

[0040] The scale plate 1 is provided with a slide groove 11, the central axis of which coincides with the diameter of the scale plate; a slider 5 is slidably connected in the slide groove 11, and the slider 5 can move left and right along the slide groove 11; a pointer 4 is movably connected to the top of the slider 5, and the pointer 4 can be rotated and adjusted relative to the slider 5. By adjusting the positions of the slider 5 and the pointer 4, and using the positioned pointer 4 as a reference standard for inspection, the subsequent steel bar hooks to be inspected can be quickly and intuitively compared and inspected.

[0041] It should be noted that, in order to facilitate the positioning of the slider 5 after adjustment, a positioning screw 53 for positioning the slider 5 is provided on the slider 5. The positioning screw 53 is threadedly connected to the slider 5. When positioning is required, it is only necessary to tighten the positioning screw 53.

[0042] Regarding the rotatable structure of the pointer 4, the following structure can be adopted:

[0043] A stud 51 is fixedly connected to the slider 5, and a through hole 41 is opened at one end of the pointer 4. The stud 51 freely passes through the through hole 41 and is threadedly connected to a fastening nut 52, which is used to press and fix the pointer 4. Principle of use: when the position of the pointer 4 needs to be adjusted, the fastening nut 52 is loosened, and then the pointer 4 is rotated. After the position of the pointer 4 is determined, the fastening nut 52 is screwed to press and fix the pointer 4.

[0044] It should be noted that: in order to prevent the slider 5 from escaping from the slide groove 11, a guide groove is opened on the side wall of the slide groove 11, and the side wall of the slider 5 has a guide rail, which can slide along the guide groove. By setting the guide rail, the slider 5 can be prevented from escaping from the slide groove 11, ensuring that the slider 5 can only slide along the slide groove 11.

[0045] The scale plate 1 is also provided with a locking mechanism for locking the ruler 3; the locking mechanism includes a connecting piece 6, which is fixedly connected to the scale plate 1; the connecting piece 6 is threadedly connected with a locking top screw 7 that can be adjusted up and down, and the connecting piece 6 is provided with a threaded hole 61, and the locking top screw 7 is matched and connected with the threaded hole 61, and the locking top screw 7 is used to press and fix the ruler 3.

[0046] The scale plate 1 is made of transparent plastic material, and acrylic material can be selected, which is durable and easy to make.

[0047] For easy operation, a knob is fixedly connected to the top of the locking top screw 7, and the knob can be a butterfly knob or a ring knob.

[0048] The bottom end of the stud 51 can freely penetrate the slider 5 and extend to the bottom of the slider 5; the slide groove 11 is a through slide groove 11, and the bottom end of the stud 51 freely penetrates the slide groove 11 and extends to the bottom of the slide groove 11. The stud 51 extending in this part can play a positioning role. When the slider 5 is sliding, the position is determined when the stud 51 hits the steel bar, which is convenient for positioning one end of the pointer 4, so that the subsequent rotation of the pointer 4 has a positioning point.

[0049] The present invention adopts the plug-in connection mode between the scale plate 1 and the ruler 3, so that the ruler 3 can be easily replaced, and the ruler 3 of appropriate length can be selected according to actual conditions, and has a wide range of applications; the plug-in connection mode is convenient for installation and disassembly, and is easy to combine, and is quick and convenient.

[0050] The present invention also provides a method for using a combined steel bar hook inspection tool, comprising the following steps:

[0051] Step 1: Select a ruler 3 of appropriate length, and connect the ruler 3 with the plug-in sleeve 2 of the circular scale plate to form a ruler;

[0052] Step 2: Prepare standard parts for steel bar hooks at various angles in advance; the hook angle of the standard part is recorded as B, and the two sides of angle B are recorded as the long side and the short side, where the short side is a straight section; select the corresponding standard part according to the steel bar hook to be inspected;

[0053] Standard parts for steel bar hooks can be prepared in advance. If you directly take the standard parts for comparison and inspection, it is not very convenient, so we use a combined ruler to adjust the inspection standards for inspection.

[0054] Step 3: align the identification line with the starting point of the straight section of the standard part, that is, align the zero scale line of the ruler 3 with the starting point of the straight section of the standard part; move the slider 5 in the slide slot 11 to adjust the position of the slider 5. After the position of the slider 5 is determined, the slider 5 is positioned and fixed by screwing the top screw; then rotate the pointer 4 so that the pointer 4 is aligned parallel to the long side of the standard part; after the position of the pointer 4 is determined, fix the pointer 4 to keep the position fixed (the pointer 4 is pressed and fixed by screwing the fastening nut 52). At this time, the ruler is the standard reference ruler;

[0055] It should be noted that since the central axis of the slide 11 is parallel to the ruler 3, that is, parallel to the straight section of the steel bar hook, the angle between the pointer 4 and the slide 11 is set to Q. According to the principle of equal equilateral angles, the angle value B of the standard part is equal to the formed angle value Q. Therefore, the angle value of the steel bar hook to be inspected can be checked based on Q.

[0056] Step 4. Use the ruler in step 3 as a reference standard to check and compare the steel bar hook to be checked. First, align the marking line with the starting point of the straight section of the steel bar hook to be checked. According to the scale of ruler 3, obtain the length of the straight section of the steel bar hook to be checked. Determine whether the requirements are met based on the straight length value obtained. Then check whether the pointer 4 is parallel to the long side of the steel bar hook to be checked to determine whether the hook angle meets the requirements.

[0057] Set the angle of the steel bar hook to be checked to D. If pointer 4 can be aligned parallel to the long side of the steel bar hook to be checked, it means that angle D is equal to Q, which means that the steel bar hook to be checked meets the requirements and meets the angle requirements of the standard parts; if pointer 4 cannot be aligned parallel to the long side of the steel bar hook to be checked, it means that there is a deviation between angles D and Q, which does not meet the requirements of the specification.

[0058] It should be noted that the scale plate 1 may be provided with angle value scales, and the scale plate may be used alone or in conjunction with the ruler 3 to measure angles. When the slider 5 is located at the center of the scale plate 1, it may be used as a protractor.

[0059] In the method of the present invention, a steel bar hook mark is used as a reference standard, and the pointer 4 and the slider 5 are adjusted to adjust the pointer 4 so that a standard hook angle is formed between the pointer 4 and the central axis of the slide 11, and this angle is used as the standard angle value for inspection; then the ruler adjusted in place is used as a reference standard, and the hook angle and the straight section are quickly and intuitively inspected to see whether they meet the construction requirements by observing the scale of the ruler 3 and the parallel alignment of the pointer 4 and the long side of the steel bar hook to be inspected. This method is simple, fast, and effective; and by utilizing the adjustability of the pointer 4, it can be applied to different angle values, and has few limitations in use.
