Description

Technical Field

[0001] This utility model belongs to the field of concrete elevation measurement technology, specifically relating to an integrated ruler for concrete leveling and scraping. Background Technology

[0002] During the concrete pouring process, workers need to monitor the elevation of the concrete surface in real time to ensure the flatness of the finished concrete surface.

[0003] However, when workers measure the elevation of the concrete surface, they need to bend over and use a ruler to measure, which not only increases the labor intensity of the workers and reduces the construction efficiency, but also easily causes indentations on the concrete surface during the measurement process, affecting the smoothness of the concrete after it is formed.

[0004] Therefore, an integrated ruler for measuring and leveling concrete was proposed. Summary of the Invention

[0005] This utility model provides an integrated ruler for measuring and leveling concrete, which aims to solve the problems mentioned above.

[0006] This utility model embodiment provides an integrated concrete leveling and smoothing ruler, including a leveling contact plate; a hand-held operating rod located at the top center of the leveling contact plate; a triangular support plate located between the outer wall of the hand-held operating rod and the top of the leveling contact plate; a movable scale sleeve sleeved on the outer wall of the hand-held operating rod; two fastening screws symmetrically screwed onto the outer wall of the movable scale sleeve; and scale lines located on the outer wall of the movable scale sleeve.

[0007] Furthermore, the cross-section of the measuring contact plate is rectangular, and the measuring contact plate is perpendicular to the hand-held operating rod;

[0008] By adopting the above technical solution, the rectangular flat contact plate can also be used for leveling, thereby performing a leveling operation on the concrete and ensuring a smooth concrete surface.

[0009] Furthermore, the measuring touch plate, the hand-held operating rod, and the triangular support plate form a triangular stable support structure with a triangular cross-section;

[0010] By adopting the above technical solution, the structural strength is ensured by the triangular stable support structure, thereby ensuring the firmness of the connection between the measuring touch plate and the hand-held operating rod.

[0011] Furthermore, one end of the fastening screw is located inside the movable scale sleeve, and one end of the fastening screw is in contact with the outer wall of the hand-held operating rod.

[0012] By adopting the above technical solution, the movable scale sleeve can be fixed at different heights on the hand-held operating rod by pressing one end of the fastening screw against it.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model integrates elevation measurement and surface leveling functions, effectively improving the efficiency and quality of concrete pouring construction. Based on infrared light or external horizontal height lines, it can accurately measure the elevation of the concrete surface by moving a graduated ruler, achieving effective control over the flatness of the finished concrete surface. It also has a leveling function, which can perform leveling operations on the concrete surface to eliminate surface bumps and depressions, ensuring the flatness of the concrete surface. It effectively avoids the cumbersome process of using different tools for measurement and leveling in traditional construction. By organically combining measurement and leveling functions, it significantly improves construction efficiency and reduces construction costs.

The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1-3 This utility model embodiment proposes an integrated concrete leveling and scraping ruler, including a leveling contact plate 1. A hand-held operating rod 2 is provided at the top center of the leveling contact plate 1. The cross-section of the leveling contact plate 1 is rectangular, and the leveling contact plate 1 and the hand-held operating rod 2 are perpendicular. Through the rectangular leveling contact plate 1, it can also perform scraping functions, thereby performing scraping operations on the concrete to ensure a smooth concrete surface. A triangular support plate 3 is provided between the outer wall of the hand-held operating rod 2 and the top of the leveling contact plate 1. The leveling contact plate 1, the hand-held operating rod 2, and the triangular support plate 3 form a triangular stable support structure with a triangular cross-section. The structure ensures structural strength, thereby ensuring the firmness of the connection between the measuring contact plate 1 and the hand-held operating rod 2. A movable scale sleeve 4 is sleeved on the outer side of the hand-held operating rod 2. Two fastening screws 5 are symmetrically screwed onto the outer wall of the movable scale sleeve 4. One end of the fastening screw 5 is located inside the movable scale sleeve 4, and the other end of the fastening screw 5 is in pressure contact with the outer wall of the hand-held operating rod 2. By pressing the hand-held operating rod 2 with the other end of the fastening screw 5, the movable scale sleeve 4 is fixed at different heights on the hand-held operating rod 2. A scale line 6 is provided on the outer wall of the movable scale sleeve 4 near the two fastening screws 5.

[0023] Below the measuring contact plate 1 is a concrete layer 7 that exists during use, and an external horizontal height line 8 that serves as a reference line (the concrete layer 7 and the external horizontal height line 8 are the environment in which the ruler is used, and are not part of the ruler).

[0024] The specific implementation method is as follows: When measuring the elevation of the concrete surface, the movable scale sleeve 4 is moved on the hand-held operating rod 2 with the help of infrared light emitted by the laser level or a preset external horizontal height line 8 (baseline), so that one of the scale lines 6 coincides with the infrared light or the external horizontal height line 8 (this scale line 6 can be the zero scale line on the movable scale sleeve 4 or a specific reference mark). At this time, the fastening screw 5 is rotated, and through the threaded connection between the fastening screw 5 and the movable scale sleeve 4, one end of the fastening screw 5 presses against the hand-held operating rod 2, fixing the movable scale sleeve 4 on the hand-held operating rod 2. During the measurement, the leveling contact plate 1 is placed on the concrete surface, and the elevation of the concrete surface is measured according to the difference between the infrared light or the external horizontal height line 8 and the scale line 6. After the elevation measurement is completed, the leveling contact plate 1 can be used directly to scrape the concrete surface to eliminate surface protrusions and depressions, ensuring the flatness of the concrete surface.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
