Description

Technical Field

[0001] This utility model belongs to the field of building construction. It can quickly measure the verticality and flatness of the surface of components such as formwork, concrete, masonry, plastering, paint, and floor. It has the characteristics of high precision, convenient operation and storage, and not easily damaged. Background Technology

[0002] With the standardization and data-driven development of the construction market, all parties involved in the construction process attach great importance to the actual measurement data of each component. During the concrete formwork stage, the verticality of the formwork needs to be measured. After the concrete formwork is removed, the vertical flatness of the concrete surface needs to be measured. After the masonry, plastering, and painting are completed, the vertical flatness of the surface needs to be measured. After the floor is completed, the surface flatness also needs to be measured. The actual measurement work is very extensive, and all parties attach great importance to accuracy. Therefore, it is particularly important to use a convenient and accurate measuring tool.

[0003] Conventional straightedges are not only bulky and have many components, making them inconvenient to carry, but also often become inaccurate or deviate in verticality after prolonged use, and are difficult or impossible to correct. Utility Model Content

[0004] To address the problems of conventional straightedges being bulky and inaccurate in terms of verticality, the present invention aims to provide a high-precision integrated vertical and flat measuring tool, which features high accuracy, convenient operation, and durability.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-precision vertical leveling integrated measuring tool includes: a main rod, with a protrusion extending from each end of the main rod in the same direction, a snap-back device 3 provided on the side of the top protrusion of the main rod, a hanging line 4 wrapped around the snap-back device 3 and which can be stretched or retracted onto the snap-back device 3, and a pendant provided at the other end of the hanging line 4; and scale lines provided on the bottom protrusion of the main rod and the pendant.

[0007] In the aforementioned high-precision vertical leveling integrated measuring tool, the protrusions are all the same in size and specifications, and their length is less than that of the main rod; the snap-back device 3 is set in the middle of the top protrusion of the main rod.

[0008] The aforementioned high-precision vertical leveling integrated measuring tool, wherein the main rod is made of a rigid metal including but not limited to aluminum alloy, and is square in shape; the main rod is a segmented structure.

[0009] The aforementioned high-precision vertical leveling integrated measuring tool has a segmented structure in which the main rods include main rod I and main rod II of the same size, which are connected by a pin 5 and can be folded along the pin 5.

[0010] The aforementioned high-precision vertical leveling integrated measuring tool has a pendulum 7 that is wedge-shaped with a thinner bottom and a thicker top. A scale line II8 is provided on the pendulum along the vertical direction, and it has its own weight to straighten the hanging line.

[0011] The aforementioned high-precision vertical leveling integrated measuring tool has a hanging line 4 with a length greater than the length of the main rod. The hanging line can be pulled out to any size and fixed, and it is automatically stored after use.

[0012] When using this tool, place the front side against the surface of the component to measure verticality and read the deviation directly. Place the back side against the surface of the component to measure flatness directly using a plumb line (which also functions as a feeler gauge).

[0013] Beneficial effects: Compared with the prior art, the advantages of this utility model are:

[0014] (1) It is easy to operate and carry, and integrates the vertical flatness detection function.

[0015] (2) The verticality accuracy is high and will not become inaccurate due to long-term use or collision.

[0016] (3) The overall structure is simple, easy to manufacture, and the parts are easy to replace or repair. Attached Figure Description

[0021] The technical solutions of the present invention will now be described in detail with reference to the accompanying drawings of the embodiments. Example

[0022] Please see Figure 1This utility model provides a high-precision integrated vertical and flatness measuring tool, comprising: a main rod, with a protrusion of equal size extending from both ends of the main rod in the same direction; a snap-back device 3 is provided on the side of the top protrusion of the main rod; a hanging line 4 is wound around the snap-back device 3, which can be stretched or retracted to the outer periphery of the snap-back device 3; and a pendant is provided at the other end of the hanging line 4. A scale line I6 is provided on the side of the bottom protrusion of the main rod; the verticality deviation is measured based on the degree of the hanging line at the scale line I6.

[0023] The main rod is made of aluminum alloy or other metals with a certain rigidity and resistance to deformation, and is square in shape. The main rod can be a single piece with a concave cross-section, or, for ease of storage, it can be segmented. Specifically, the main rod includes two main rods, I and II, of the same size, connected by a pin 5, and foldable along the pin 5. The folded state is shown in the image. Figure 2 As shown.

[0024] The aforementioned pendant 7 has a wedge-shaped cross-section (thinner at the bottom and thicker at the top). Horizontal graduation lines are provided on both sides of the pendant 7 along the vertical direction. It has a certain self-weight and can straighten the hanging line by gravity. Another function of the pendant 7 is as a feeler gauge. When measuring flatness, the pendant 7 is inserted into the gap to measure the flatness deviation.

[0025] Figure 3 This is a schematic diagram of the measurement principle of this utility model; see reference. Figure 3 As shown, the utility model is used in the following ways:

[0026] (1) When the main members are segmented, main members I and II need to be opened first, and then folded and stored after inspection. When the main members are integrated, they can be used directly.

[0027] (2) When measuring verticality, pull out the plumb line 7, place the protrusions at both ends of the main rod against the surface of the component, and read the degree at the scale line 6 when the lower hanging line is in a drooping state to measure the verticality deviation.

[0028] (3) When measuring flatness, retract the plumb bob 7, place the main member against the surface of the structure, and use the plumb bob 7 (which is used as a feeler gauge at this time) to insert into the gap position to measure the flatness deviation.
