Description

Technical Field

[0001] This utility model relates to the field of construction engineering management, specifically a construction engineering management inspection ruler. Background Technology

[0002] Construction project management is a systematic undertaking that plans, organizes, and controls the entire process of a construction project, from planning and construction to completion, aiming to ensure the achievement of project quality, safety, schedule, and cost objectives. In this process, a measuring ruler, as a key quality control tool, can accurately measure parameters such as wall flatness, verticality, and levelness, which directly affect the acceptance standards for construction quality and are an important means of ensuring project compliance and safety. Existing measuring rulers (such as straightedges, spirit levels, and vertical measuring rulers) are typically made of high-precision aluminum alloy or carbon fiber. Structurally, they include a main ruler body, a bubble level (level), a sliding probe, or a digital display screen. Their use primarily relies on manual operation. The measuring ruler is placed firmly against the wall to be measured, and the flatness deviation is judged by observing the gap between the ruler and the wall or reading the data on the digital display. Alternatively, the position of the bubble level can be used to determine the horizontal or vertical status.

[0003] The applicant believes that the shortcomings of the existing engineering management inspection ruler are as follows: 1. The inspection results are affected by the condition of the wall: When the wall surface being inspected has bulges, unevenness, or other irregularities, the fit between the inspection tool and the wall surface is affected, making it impossible to accurately obtain data on the actual condition of the wall surface. This leads to a large error in the inspection results, making it difficult to guarantee the accuracy and reliability of the inspection; 2. Functional limitations: The existing inspection tools have relatively simple functions and lack the ability to inspect right angles. In scenarios such as building acceptance and decoration quality control, it is difficult to meet comprehensive inspection needs.

[0004] To address these issues, we propose a construction project management and inspection ruler. Utility Model Content

[0005] The purpose of this utility model is to provide a construction engineering management and inspection ruler to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction engineering management and inspection ruler, including a main ruler and a level, one end of the main ruler is connected to a secondary ruler, and both the main ruler and the secondary ruler are provided with hollow handles; a shovel is inserted at the middle position of the end of the secondary ruler away from the main ruler, and a groove is opened on the side of the main ruler, and a rectangular frame is fixedly embedded in the groove.

[0007] Preferably, the sides of the main scale and the secondary scale are provided with scale marks, and the sides of the scale marks are at the same horizontal position as the side of the main scale with the rectangular frame. This design makes it easy for the device to be perpendicular to and closely fit the wall surface to be tested, while also being able to measure the length of the wall surface.

[0008] Preferably, the main scale has slots on its top and side surfaces, and the auxiliary scale has a locking block that mates with the slots fixedly connected to one end. A knurled locking bolt that mates with the locking block is threaded into the front of the main scale. The knurled locking bolt can fix the locking block on the main scale to prevent it from shifting and affecting the accuracy and reliability of the measurement results.

[0009] Preferably, the level is provided in three sets, and two sets of the level are assembled by rotating cylinders. The two sets of the level are respectively assembled at one end of the main scale and the auxiliary scale by rotating cylinders. Both sets of rotating cylinders are rotatably embedded in the main scale and the auxiliary scale. The level is fixedly installed in the middle position of the rotating cylinder. Multiple sets of level can detect the levelness of the device and the wall to be measured over a wider range, making the measurement results more reliable.

[0010] Preferably, the bottom of another set of rotating cylinders is provided with a T-shaped slider. The bottom surface of the rectangular frame is provided with a T-shaped groove that matches the T-shaped slider. The T-shaped groove has the same internal length as the rectangular frame. The T-shaped slider and the T-shaped groove are interference-fitted. The design of the T-shaped groove allows the level to slide up and down. The interference fit structure prevents the T-shaped slider from sliding down automatically on the T-shaped groove, thus fixing the level on the T-shaped slider and facilitating the detection of the flatness of specific locations on the wall.

[0011] Preferably, the scraper is movably inserted into the vernier scale, and a push rod is fixedly connected to the bottom of the scraper. The outer surface of the vernier scale has a groove that matches the push rod. A star-shaped locking bolt is threaded into the vernier scale at the front end of the push rod. The bottom end of the scraper has a limiting hole that matches the star-shaped locking bolt. This design can remove bumps, bulges, etc. on the wall surface, making the measurement results more accurate. At the same time, the combined use of the push rod and the star-shaped locking bolt can store the scraper in the vernier scale, avoiding accidental scratches.

[0012] This utility model provides a construction engineering management and inspection ruler, which has the following beneficial effects: The scraper design effectively removes unevenness such as bulges on the wall, ensuring a tight fit between the measuring tool and the wall surface and effectively avoiding measurement errors caused by unevenness. The combination of the push rod and the locking bolt allows the scraper to be stored in the vernier scale, preventing accidental damage. Furthermore, the T-shaped slider design allows the level to move along the groove, expanding the level's detection range and improving the accuracy and reliability of the measurement results.

[0013] By using the main ruler, the auxiliary ruler, and the slot together, the auxiliary ruler can be inserted from the top of the main ruler to the side of the main ruler and fixed with a plum blossom locking bolt, transforming the device into a right-angle ruler. By observing the position of the bubble in the level on the right-angle ruler, it can be determined whether the corner meets the standard. This expands the function from simple flatness detection to right-angle measurement of the corner, giving the device multi-dimensional detection capabilities and meeting the dual detection needs of corner angle and wall flatness in scenarios such as building decoration.

Detailed Implementation The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This embodiment proposes a construction project management and inspection ruler. Example 1 like Figures 1 to 4As shown, this embodiment proposes a construction engineering management inspection ruler, including a main ruler 1 and a level 6. One end of the main ruler 1 is connected to a secondary ruler 2, and both the main ruler 1 and the secondary ruler 2 are provided with hollow handles 4. A scraper 7 is inserted into the middle of the end of the secondary ruler 2 away from the main ruler 1. A groove is opened on the side of the main ruler 1, and a rectangular frame 10 is fixedly embedded in the groove. Scale marks are provided on the sides of the main ruler 1 and the secondary ruler 2, and the side of the scale marks is at the same horizontal position as the side of the main ruler 1 with the rectangular frame 10. The level 6 is provided in three sets, two of which are... The level 6 is assembled via the rotating cylinder 5. The two sets of level 6 are respectively assembled at one end of the main scale 1 and the auxiliary scale 2 via the rotating cylinder 5. Both sets of rotating cylinder 5 are rotatably embedded in the main scale 1 and the auxiliary scale 2. The level 6 is fixedly installed in the middle position of the rotating cylinder 5. The scraper 7 is movably inserted into the auxiliary scale 2. The bottom of the scraper 7 is fixedly connected to the push rod 8. The outer surface of the auxiliary scale 2 has a groove that matches the push rod 8. A pendant lock bolt 9 is threaded into the auxiliary scale 2 at the front end of the push rod 8. The bottom end of the scraper 7 has a limiting hole that matches the pendant lock bolt 9.

[0017] In the above embodiment, when encountering unevenness on the wall surface during the inspection process, the plum blossom locking bolt 9 can be unscrewed from the auxiliary ruler 2, the push rod 8 can be pushed forward until the end of the groove, and then the plum blossom locking bolt 9 can be screwed back in to fix the scraper 7. The scraper 7 can then be used to remove the bulges on the wall surface. After use, the plum blossom locking bolt 9 can be unscrewed, the push rod 8 can be moved backward to move the scraper 7 to the end of the groove, and then the plum blossom locking bolt 9 can be tightened to fix the scraper 7 and prevent it from coming out. After removing the bulges, protrusions, etc. on the wall surface with the scraper 7, the scraper 7 can be retracted into the main ruler 1 and locked by the plum blossom locking bolt 9 to avoid accidental skin injury. At this time, the wall flatness can be inspected. The inspector holds the hollow handle 4, so that the side with the scale is in contact with the wall surface, and keeps it in place. While maintaining a vertical position, observe whether the bubbles in multiple sets of levels 6 are in the center position. When measuring a specific location, move the T-shaped slider 11 along the slide rail to that position. Once the bubble in the level 6 is in the center, use a feeler gauge to measure the distance between the measuring ruler and the wall gap. The scraper 7 is designed to remove unevenness such as bulges on the wall, ensuring a tight fit between the measuring tool and the wall, effectively avoiding measurement errors caused by unevenness. The push rod 8 and the plum blossom locking bolt 9 work together to store the scraper 7 in the auxiliary ruler 2, preventing accidental scratches. Compared to traditional measuring rulers, the T-shaped slider 11 allows the level 6 to move on the slide rail, expanding the measuring range of the level 6 and improving the accuracy and reliability of the measurement results.

[0018] Example 2 like Figure 1 and Figure 5As shown, based on the same concept as the above embodiment, this embodiment also proposes: a slot is provided on the top and side surfaces of one end of the main ruler 1, and a locking block that cooperates with the slot is fixedly connected to one end of the secondary ruler 2. A knurled locking bolt 3 that cooperates with the locking block is threaded into the front position of the main ruler 1. A T-shaped slider 11 is provided at the bottom of another set of rotating cylinders 5. A T-shaped groove that cooperates with the T-shaped slider 11 is provided on the bottom surface of the rectangular frame 10. The T-shaped groove has the same internal length as the rectangular frame 10. The T-shaped slider 11 and the T-shaped groove are interference fit.

[0019] In the above embodiment, when it is necessary to check for deviations at the corners of walls during construction project management and inspection, the knurled locking bolt 3 on the back of the device needs to be unscrewed, the auxiliary ruler 2 is taken out from the top of the main ruler 1, and then inserted into the slot on the side of the main ruler 1. After the connection is tight, the knurled locking bolt 3 is inserted into the main ruler 1 and tightened, thus transforming the device into a right-angle ruler. The right-angle side of the measuring ruler is aligned with the wall, and multiple sets of levels 6 are observed simultaneously. The bubble in the level 6 is centered. When checking a specific position, the T-shaped slider 11 can be slid. The cooperation between the T-shaped slider 11 and the T-shaped groove can move the level 6 to that position. Then, the position of the device is adjusted so that the bubble in the level 6 is centered. By keeping the corner centered, the standard of the corner can be determined. For more precise data, a feeler gauge can be used to measure the gap width between the measuring ruler and the wall to check whether the corner meets the standard. Compared with traditional single-function measuring rulers, this device uses the main ruler 1, the auxiliary ruler 2 and the slot to connect the auxiliary ruler 2 from the top of the main ruler 1 to the side of the main ruler 1, transforming the device into a right-angle ruler. By observing the position of the bubble in the level 6, the standard of the corner can be determined. This expands the function from single flatness detection to right-angle measurement of the corner, giving the device multi-dimensional detection capabilities and meeting the dual detection needs of corner angle and wall flatness in building decoration and other scenarios.
