Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, in particular to a slope ruler for controlling the slope of foundation pit excavation. Background Art

[0002] Slope excavation means that when digging the foundation of a civil building, for the sake of safety, a sufficient slope should be left at the edge when a certain depth is reached. In other words, when digging the soil, you cannot continue digging straight up and down, but should increase the width at the top to form a slope, and then dig down to prevent the soil wall from collapsing; during the construction process, the slope of the mechanical brush is not uniform, and it needs to be measured repeatedly. Different construction requirements have different slope requirements, and the measuring ruler needs to have good applicability. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a slope ruler for controlling the slope of foundation pit excavation. During the construction process, the problem of inconsistent and uneven slopes caused by mechanical slope brushing is solved, and the problem of repeated slope brushing during the slope brushing process is solved.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A slope ruler for controlling the slope of foundation pit excavation, comprising a U-shaped seat and a level ruler installed thereon, wherein one end of the U-shaped seat is rotatably connected to a rod body b, and the other end is rotatably connected to a rod body a, and the end of the rod body a away from the U-shaped seat is connected to the rod body b through a locking structure, and the side wall of the U-shaped seat is provided with an angle measuring structure, which is arranged concentrically with the rotation center of the rod body b.

[0006] Preferably, the locking structure comprises a sliding seat slidably mounted on the rod body b, the sliding seat is rotatably connected to an end of the rod body a away from the U-shaped seat, and a locking member is provided on the side of the sliding seat away from the rod body a.

[0007] Preferably, the locking member comprises a locking bolt threadedly connected to the side wall of the slide seat, and one end of the locking bolt away from the slide seat is rotatably connected to a folding buckle.

[0008] Preferably, the angle measuring structure comprises an angle ruler arranged on the side wall of the U-shaped seat, and an angle pointer is coaxially arranged at the rotation center of the rod body b.

[0009] Preferably, the angle pointer is arranged parallel to the rod body b.

[0010] Compared with the prior art, the utility model has the following beneficial effects: according to the on-site construction requirements, the utility model adjusts the position of the slide seat on the rod body b while ensuring that the level ruler is horizontal, and locks it with a locking bolt. At this time, the angle pointer on the angle ruler points out the corresponding angle, that is, the angle between the U-shaped seat and the rod body b. Then, the rod body b is attached to the slope surface to measure the slope angle of the slope surface. During the construction process, the ruler can be used to dynamically measure the control of the slope finishing slope, thereby improving the construction efficiency.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-4 A slope ruler for controlling the slope of foundation pit excavation, comprising a U-shaped seat 1 and a level ruler 2 installed thereon, one end of the U-shaped seat 1 is rotatably connected to a rod b4, and the other end is rotatably connected to a rod a3, the end of the rod a3 away from the U-shaped seat 1 is connected to the rod b4 through a locking structure, and an angle measuring structure is arranged on the side wall of the U-shaped seat 1, and the angle measuring structure is arranged concentrically with the rotation center of the rod b4.

[0019] According to the on-site construction requirements, while ensuring that the level ruler 2 is horizontal, adjust the position of the slide 5 on the rod body b4 and lock it with the locking bolt 8. At this time, the angle pointer 7 points out the corresponding angle on the angle ruler 6, that is, the angle between the U-shaped seat 1 and the rod body b4. Then, stick the rod body b4 on the slope surface to measure the slope angle of the slope surface. During the construction process, the ruler can be used to dynamically measure the control of the slope finishing slope to improve the construction efficiency.

[0020] In this embodiment, the locking structure includes a slide seat 5 slidably mounted on the rod body b4, and the slide seat 5 is rotatably connected to the end of the rod body a3 away from the U-shaped seat 1. A locking piece is provided on the side of the slide seat 5 away from the rod body a3 to fix the relative position of the rod body a3 and the rod body b4. In addition, the rod body a3 and the rod body b4 can be folded into the U-shaped seat 1 and locked to reduce their volume for easy carrying.

[0021] In this embodiment, the locking member includes a locking bolt 8 threadedly connected to the side wall of the slide 5. The end of the locking bolt 8 away from the slide 5 is rotatably connected to a folding buckle 9. When the rod body b4 is in contact with the slope surface, the folding buckle 9 is folded up to avoid bulging, which causes the rod body b4 to be unevenly fitted with the slope surface.

[0022] In this embodiment, the angle measuring structure includes an angle ruler 6 arranged on the side wall of the U-shaped seat 1, and an angle pointer 7 is coaxially arranged at the rotation center of the rod body b4 for intuitively reading the slope angle.

[0023] In this embodiment, the angle pointer 7 is arranged parallel to the rod body b4.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
