Description

Technical Field

[0001] The utility model relates to a rib height measuring gauge for ribbed steel bars. Background Art

[0002] At present, many steel structures in engineering structures use ribbed steel bars (such as Figure 1 ) to improve the ability of concrete to resist the sliding of steel bars after construction, so the rib height of the steel bars (such as Figure 2 ) is particularly important and needs to be accurately measured during the design process. The traditional measurement method is to use a vernier caliper to measure directly. This not only requires the ruler of the measuring ruler to be perpendicular to the main body of the steel bar, but also because the side head cannot be accurately stuck at the highest point of the rib height, it will cause dimensional errors; at the same time, if the maximum position of the steel bar rib height is uncertain, the measured size will not be the maximum value of the rib height, affecting the subsequent dimensional design.

[0003] Therefore, a simple, fast and accurate device is currently needed to measure the rib height of ribbed steel bars. Utility Model Content

[0006] Furthermore, the distance measuring gear and the dial indicator are connected through a linkage bearing and a dry set to achieve synchronous rotation.

[0007] Furthermore, a spring rod is provided on one side of the height measuring rod. The spring rod is located on one side of the height measuring rod, one end of which is fixedly connected to the height measuring rod and extends outward along the side of the height measuring rod; one end is connected to the measuring gauge main board through a spring, and the height measuring rod is forcibly pulled back by the spring tension, so that the height measuring rod is pressed on the highest rib height of the steel bar to be measured.

[0008] Furthermore, an adjustment slot is provided on the gauge main board, and the adjustment slot is arranged horizontally on the gauge main board, matched with the fixed measuring rod, and the direction is perpendicular to the fixed measuring rod.

[0009] Furthermore, the adjustment slots are provided with two and are connected to the fixed measuring rod via bolts and nuts, so as to adjust the lateral position of the fixed measuring rod and the distance between the fixed measuring rod and the height measuring rod.

[0010] Furthermore, a measuring arc is provided at the bottom of the fixed measuring rod, and the measuring arc is used to match the outer circle of the steel bar to be measured and locate the position of the measuring gauge mainboard.

[0011] Furthermore, a rotating shaft and a height measuring head are provided at the bottom of the height measuring rod, and the rotating shaft is located between the height measuring rod and the height measuring head, connecting the height measuring head and the height measuring rod so that the height measuring head can rotate freely at the bottom of the height measuring rod; the height measuring head has an arc shape, and is used to contact the highest point of the rib height on the steel bar to be measured.

[0012] Furthermore, the arc arrangement direction of the height measuring head is perpendicular to the rib height of the steel bar to be measured, and wraps the highest point of the rib height.

[0013] Compared with the prior art, the utility model provides a rib height measuring gauge for ribbed steel bars, which uses a fixed measuring rod to position the steel bars, and then uses the height measuring head on the height measuring rod to contact the highest point of the steel bar rib height, and through the upward movement of the height measuring rod, drives the dial indicator to rotate, and forms a reading to obtain the height value of the rib height. Since the height measuring head adopts an arc design, the highest point of the rib height can be captured, and the rack on the height measuring rod cooperates with the distance measuring gear to achieve the accuracy of the rib height measurement; the fixed measuring rod can move freely in the adjustment groove through the bolt, and then the relative position between the fixed measuring rod and the height measuring rod can be adjusted, which can adapt to products of different sizes and expand the use range of the gauge; at the same time, the structure is simple and reliable, easy to carry and convenient to use.
