Description

Technical Field

[0001] This utility model relates to the field of mechanical measuring equipment, specifically a tool for quickly checking the verticality of vertical templates. Background Technology

[0002] Currently, with the rapid development of the construction industry and the increasing diversity and complexity of building forms, higher requirements are being placed on the verticality inspection of formwork during construction. Especially in high-rise building construction, the verticality of the formwork is directly related to the safety and stability of the structure. However, existing formwork verticality inspection technologies have significant limitations.

[0003] Traditionally, construction workers often use simple measuring tools such as plumb lines and spirit levels to check the verticality of formwork. Plumb lines are usually used to check the verticality of local areas, but when dealing with large areas or high formwork, it is difficult to guarantee the accuracy and comprehensiveness of the measurement.

[0004] Furthermore, while these tools can meet basic needs to a certain extent, their limitations become apparent when dealing with tall and complex templates. Plumb lines are easily affected by external factors such as wind, leading to inaccurate measurements, and can only check the verticality of localized areas. For large areas or tall templates, it's difficult to guarantee accuracy and comprehensiveness. While spirit levels can measure levelness, they are inadequate for measuring verticality, especially in angle measurements. Their accuracy is often affected by the operator's skill and experience, and they are not suitable for measuring complex template structures.

[0005] In addition, there are some more advanced surveying instruments on the market, such as laser rangefinders and total stations. While these instruments offer high precision and versatility, they also present some challenges in practical applications. First, their higher price increases construction costs. Second, their complex operation requires specialized personnel for both operation and maintenance, placing higher technical demands on on-site workers. Finally, these instruments are susceptible to factors such as weather and power supply fluctuations, limiting their application scenarios and reliability. Utility Model Content

[0006] The present invention aims to overcome the defects of the prior art and provide a tool for quickly checking the verticality of vertical templates, solving the problem of how to conveniently and quickly check whether the verticality of vertical templates meets the specified requirements during and after assembly.

[0007] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0008] A tool for quickly checking the verticality of a vertical template, characterized in that it comprises:

[0009] The upper steel cube and the lower steel cube can be connected;

[0010] The cord reel is fixedly installed on the upper steel cube and connected via a central rotating shaft;

[0011] A rotary gear selector, connected to a cable reel, is used to control its rotation;

[0012] A nylon rope is wound around a rope reel, with one end connected to a lower steel cube.

[0013] A scale, set on the upper or lower steel cube, is used to measure the angle between the nylon rope and the scale.

[0014] The support rod and center of gravity are set on the lower steel cube to ensure that the lower steel cube remains horizontally balanced after release.

[0015] The tool for quickly checking the verticality of a vertical template is characterized in that: the upper steel cube and the lower steel cube form an integral structure when connected, which is convenient for carrying and storage.

[0016] The tool for quickly checking the verticality of a vertical template is characterized in that: the rope reel is controlled to rotate by a rotating lever, thereby releasing or retracting the nylon rope, causing the lower steel cube to descend or rise.

[0017] The tool for quickly checking the verticality of a vertical template is characterized in that: the upper steel cube has a surface that contacts the vertical template, the surface of which is flat and perpendicular to the other surfaces of the upper steel cube to ensure a tight fit with the template surface.

[0018] The tool for quickly checking the verticality of a vertical template is characterized in that: the lower steel cube has a hollow metal structure to reduce weight while maintaining sufficient strength; the center of gravity is located at the geometric center of the lower steel cube to ensure that it can maintain horizontal balance under the action of gravity; and a dial is arranged on one face of the lower steel cube for reading the deviation angle.

[0019] The beneficial effects of this utility model are as follows: As can be seen from the above technical solution, this application provides a tool for quickly checking the verticality of a vertical template. This tool utilizes the characteristic that all angles of a cube are right angles, and employs a scale that can be configured on a metal hollow cube to design a simple, compact, and easy-to-use measuring tool. This tool is unaffected by weather, power supply, or other factors, and is easy to carry. It can check the verticality of the vertical template throughout its entire lifecycle, avoiding the need for subsequent rectification and repair due to template misalignment, thus saving significant manpower and resources.

[0020] This application utilizes the characteristic that all angles of a cube are right angles, and the scale dials arranged on the metal hollow cube, to accurately and quickly check the verticality of a vertical template. Compared with traditional tools, such as plumb lines and spirit levels, this tool can better ensure the accuracy and comprehensiveness of measurements when measuring large areas or high templates.

[0021] The tool is designed to be simple and straightforward, with no complicated operating procedures. On-site workers simply control the rotation of the rope reel by turning the lever, releasing or retracting the nylon rope to raise or lower the lower steel cube for measurement. The dial readings are also intuitive and easy to understand, allowing workers to quickly master and become proficient in using the tool.

[0022] Not only is it suitable for checking the verticality of formwork in tall buildings, but it is also suitable for measuring formwork in other complex structures. Its simple and compact design makes the tool easy to carry and store, and it can detect the verticality of vertical formwork at any time and throughout its entire life cycle.

[0023] Compared to more advanced surveying instruments on the market, such as laser rangefinders and total stations, this tool is more affordable and does not require professional operation or maintenance. Furthermore, because it is unaffected by weather or power supply issues, it can operate continuously and stably, thus avoiding economic losses due to instrument malfunctions or errors.

[0024] By using this tool, construction workers can promptly identify and adjust misaligned formwork, avoiding the need for corrections and repairs after the structure has been completed. This not only improves construction quality but also reduces the costs and safety risks associated with corrective actions. Attached Figure Description

[0031] like Figure 1-3 As shown: A tool for quickly checking the verticality of a vertical template, which includes:

[0032] The upper steel cube 1 and the lower steel cube 6 can be connected;

[0033] The cord reel 2 is fixedly installed on the upper steel cube 1 and connected through the central rotating shaft 4;

[0034] A rotary lever 3, connected to the rope reel 2, is used to control its rotation; by rotating the lever, the nylon rope can be released or retracted, thereby controlling the raising and lowering of the lower steel cube. This design makes the measurement process more flexible and convenient.

[0035] Nylon rope 5 is wound around the rope reel 2, and one end of it is connected to the lower steel cube 6;

[0036] The scale 8 is set on the upper steel cube 1 or the lower steel cube 6 and is used to measure the angle between the nylon rope 5 and the scale 8.

[0037] The support rod 9 and the center of gravity 7 are set on the lower steel cube 6 to ensure that the lower steel cube 6 can maintain horizontal balance after release.

[0038] The upper steel cube 1 and the lower steel cube 6 form a single integrated structure when connected, facilitating portability and storage. This design ensures stability and accuracy during measurement.

[0039] The rope reel 2 is controlled to rotate by rotating the lever 3, thereby releasing or retracting the nylon rope 5, causing the lower steel cube 6 to descend or rise.

[0040] The upper steel cube has a surface that contacts the vertical template. This surface is flat and perpendicular to the other surfaces of the upper steel cube to ensure a tight fit with the template surface.

[0041] The lower steel cube has a hollow metal structure to reduce weight while maintaining sufficient strength; the center of gravity is located at the geometric center of the lower steel cube to ensure that it can maintain horizontal balance under the action of gravity; the dial is arranged on one face of the lower steel cube for reading the deviation angle.

[0042] During measurement, place one face of the upper steel cube against the vertical template surface, and release the nylon rope by rotating the lever to lower the lower steel cube until one side of the lower steel cube coincides with the edge of the angle between the template and the ground. At this time, observe the angle reading on the scale. If the angle is 90 degrees, the template is vertical; otherwise, determine the deviation angle based on the reading and make adjustments.

[0043] Working principle:

[0044] When measuring the verticality of the template, place one face of the upper steel cube against the template surface.

[0045] The lower steel cube is lowered by rotating the gear lever to release the nylon rope.

[0046] The lower steel cube is used to maintain horizontal balance by utilizing its gravity and passing through the center of gravity.

[0047] Align one side of the lower steel cube with the side of the angle between the template and the ground.

[0048] Observe the angle on the dial at this time. If the angle is 90 degrees, the template is vertical. If the angle is not 90 degrees, the deviation angle can be determined according to the reading on the dial and adjusted in time.

[0049] Compared to conventional measuring instruments, this tool is more portable and easier to use. It can be used for measuring templates with various complex structures, unaffected by weather, power supply, or other factors. It accurately measures the verticality of the template and provides specific deviation angles. Field workers can quickly learn and master its use, improving work efficiency. Compared to expensive laser rangefinders and total stations, this tool is lower in cost and easier to promote and apply.
