Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of road engineering construction, in particular to a ruler for controlling the paving thickness of asphalt concrete. Background Art
[0002] During the asphalt concrete paving process, the paving thickness fluctuates easily due to the impact of the transport vehicle, hydraulic system pressure relief, baseline error and other factors during the paving process of the paver. The traditional control method generally uses manual measurement, that is, using a screwdriver with a ruler to control the thickness and correct the paving thickness deviation in time. When the traditional method determines the loose paving thickness, after the screwdriver is vertically inserted into the top surface of the lower bearing layer, the screwdriver is pinched with the finger according to the top of the loose asphalt concrete surface layer, and then the screwdriver is pulled out, and the distance between the finger and the screwdriver tip is measured with a ruler to obtain the loose paving thickness of the asphalt concrete. When measuring the thickness by the traditional method, it is greatly affected by human factors. When the human perspective is different, the top surface position of the loose asphalt concrete surface layer will be slightly different, which will lead to the measurement thickness error, which is easy to cause uneven thickness of the asphalt concrete surface layer, cost waste, unqualified construction quality and even rework. In addition, in order to improve the control accuracy, the paving thickness control personnel often observe slowly; in addition, the traditional method is easy to cause finger burns during the thickness piercing process. In the prior art, there is a road structure layer Matsuura thickness measuring tool and a method for using the tool. When measuring, a substrate is first placed on the top surface of the paved structure layer, so that the substrate and the structure layer are closely attached and the measuring ruler is perpendicular to the ground. A plurality of gears are rotated to drive the measuring ruler into the structure layer through meshing transmission. When the plurality of gears cannot rotate, the end of the measuring ruler reaches the bottom surface of the structure layer, and the loose paving thickness of the structure layer is recorded by reading the scale line. However, this measuring tool inserts the measuring ruler into the ground, and the measuring ruler is easily damaged. Moreover, the required length of the measuring ruler is long, resulting in a long length of the entire measuring tool, which is inconvenient to store and carry. Moreover, the measuring ruler not only needs to have a scale but also needs to be able to be inserted into the ground. If the measuring ruler needs to be replaced due to damage, the measuring ruler needs to be remade, which is costly. Utility Model Content

If the measuring ruler needs to be replaced due to damage, it is also necessary to remake the measuring ruler, which is costly.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0031] See also Figure 1 and Figure 2 To describe this embodiment, the utility model provides a scale for controlling the paving thickness of asphalt concrete, the scale for controlling the paving thickness of asphalt concrete comprises a flat head steel chisel 1, a slide rail 2 and a steel ruler 3, the slide rail 2 is fixedly arranged on the flat head steel chisel 1, the slide rail 2 has a slide groove, the extension direction of the slide groove is parallel to the extension direction of the flat head steel chisel 1, the steel ruler 3 is slidably arranged in the slide groove, a limiting structure is fixedly arranged at one end of the steel ruler 3 facing the tip of the flat head steel chisel 1, the limiting structure has a limiting surface 5, when the limiting surface 5 and the tip of the flat head steel chisel 1 are located in the same plane, the reading of the steel ruler 3 is zero.
[0032] After the asphalt concrete is paved and before rolling, the asphalt concrete paving thickness is detected using the ruler for controlling the asphalt concrete paving thickness. First, the ruler for controlling the asphalt concrete paving thickness is raised to the highest point, and then the flat-head steel bar 1 is vertically inserted into the asphalt concrete pavement until the tip of the flat-head steel bar 1 reaches the top surface of the underlying layer, and then the steel ruler 3 is slid downward so that the limiting surface 5 of the limiting structure on the steel ruler 3 is closely attached to the top surface of the asphalt concrete. The reading of the steel ruler 3 at this time is the asphalt concrete paving thickness. It can be understood that the reading end of the steel ruler 3 is located at the end away from the tip of the flat-head steel chisel 1. When the limit surface 5 and the tip of the flat-head steel chisel 1 are located in the same plane, the reading of the steel ruler 3 is zero. When the flat-head steel chisel 1 is inserted into the asphalt concrete pavement and the limit surface 5 is in close contact with the top surface of the asphalt concrete, the reading of the steel ruler 3 is the distance that the steel ruler 3 moves relative to the flat-head steel chisel 1. When the tip of the flat-head steel chisel 1 reaches the top surface of the underlying layer and the limit surface 5 is in close contact with the top surface of the asphalt concrete, the reading of the steel ruler 3 at this time is the asphalt concrete paving thickness.
[0033] The ruler for controlling the paving thickness of asphalt concrete determines the top surface of asphalt concrete by the way that the limiting surface 5 is closely attached to the top surface of asphalt concrete, and the determination of the top surface of asphalt concrete is more accurate, which overcomes the defect of determining the top surface of asphalt concrete by naked eyes, greatly eliminates the influence of human factors, and can avoid the direct contact between the fingers of the operator and the asphalt concrete, and also plays a role in labor protection for the operator. The ruler for controlling the paving thickness of asphalt concrete has a simple structure, is easy to operate, and can improve work efficiency. When the ruler for controlling the paving thickness of asphalt concrete is used, the flat head steel chisel 1 is inserted into the road surface, and the steel plate ruler 3 slides relative to the flat head steel chisel 1. Compared with the road structure layer Matsuura thickness measuring tool in the prior art, it is not only not easy to damage the steel plate ruler 3, but also the required length of the flat head steel chisel 1 is smaller, so that the overall length of the ruler for controlling the paving thickness of asphalt concrete is small, which is convenient for storage and carrying, and if the flat head steel chisel 1 is damaged, only the flat head steel chisel 1 needs to be replaced, and the flat head steel chisel 1 is a conventional part, and does not need to be remade, and the required cost is low.
[0034] Optionally, the scale for controlling the paving thickness of asphalt concrete further includes a locking structure, which can lock the relative positions of the flat-head steel chisel 1 and the steel ruler 3. When the tip of the flat-head steel chisel 1 reaches the top surface of the underlying layer, and the limiting surface 5 of the limiting structure on the steel ruler 3 is in close contact with the top surface of the asphalt concrete, the relative positions of the flat-head steel chisel 1 and the steel ruler 3 are locked by the locking structure, and the flat-head steel chisel 1 can be pulled out and then the reading of the steel ruler 3 can be read. This makes the scale for controlling the paving thickness of asphalt concrete more convenient to read.
[0035] Specifically, the locking structure is a locking top screw 7, a locking hole is provided on the side wall of the slide rail 2, the locking top screw 7 is threadedly connected to the locking hole, and the locking top screw 7 can abut against the side wall of the steel ruler 3. When the locking top screw 7 is separated from the steel ruler 3, the steel ruler 3 can slide relative to the slide rail 2, and when the locking top screw 7 is rotated to make the locking top screw 7 abut against the steel ruler 3, the relative position of the steel ruler 3 and the slide rail 2 can be locked, and the slide rail 2 is fixedly connected to the flat head steel drill 1, so that the locking top screw 7 can lock the relative position of the steel ruler 3 and the flat head steel drill 1.
[0036] Optionally, the limiting structure is a limiting steel plate 4, the limiting steel plate 4 is vertically arranged with the steel ruler 3, and the side of the limiting steel plate 4 away from the steel ruler 3 is a limiting surface 5. In this embodiment, the limiting steel plate 4 is welded to the steel ruler 3.
[0037] Optionally, a lifting steel plate 6 is fixedly provided at one end of the steel ruler 3 away from the tip of the flat head steel chisel 1. The lifting steel plate 6 is convenient for the operator to hold, and the operator can more conveniently control the sliding of the steel ruler 3 by lifting the steel plate 6.
[0038] Optionally, the lifting steel plate 6 is arranged vertically to the steel plate ruler 3, which is more convenient for operators to hold.
[0039] Optionally, one end of the lifting steel plate 6 close to the tip of the flat head steel chisel 1 can abut against the slide rail 2, so as to prevent the steel plate ruler 3 from escaping from the slide rail 2.
[0040] Optionally, the flat head steel drill 1 is fixedly provided with a handle 8, which is convenient for an operator to hold the flat head steel drill 1.
[0041] Optionally, the handle 8 is made of wood or plastic.
