Description

Technical Field

[0001] This utility model relates to the field of verticality measurement technology, and in particular to a portable verticality measuring device. Background Technology

[0002] In construction engineering, the main measured items for cast-in-place concrete structures generally include column verticality, wall surface flatness, and wall verticality. Measuring verticality can reflect the quality of the forming process. Measuring the verticality of wall and column formwork before concrete pouring can also help control the verticality of the concrete structure in advance.

[0003] A search revealed a Chinese patent with publication number CN202121054177.1, which discloses a device for measuring the verticality of wall formwork. The device involves placing the ends of the upper and lower measuring rods furthest from the vertical support rod against the wall formwork, allowing a plumb bob to hang naturally, and then observing the positional relationship between the string in the plumb bob and the mark on the lower measuring rod to determine the verticality of the wall formwork. This device is simple to operate, allowing one person to measure the verticality of the formwork, saving manpower and improving the efficiency of measuring the verticality of wall formwork. The sliding rod can slide along the connecting rod, allowing adjustment of the length of the vertical support rod, making the device suitable for floors of different heights. By setting the connecting rod as a folding structure, the device can be folded for easy storage, and the stored device is easy for operators to carry and move in floors with full scaffolding.

[0004] The above-mentioned technical solution has the following drawbacks. Although such a verticality measuring device can be stored through a folding structure to reduce its footprint and facilitate loading and transportation, it is usually stored only after use in actual construction sites. To facilitate the movement and use of the verticality measuring device on the construction site, and to facilitate stable storage after use, making it easy to carry, a portable verticality measuring device is proposed. The verticality measuring device can be extended and retracted as needed to adjust the measurement point, thus having better applicability. The whole device has a retractable and foldable structure, which is easy to fold and store, making it easy to carry and transport. It is equipped with a mobile base that is easy to assemble and disassemble, so that the verticality measuring device can be connected to the mobile base, making it easy to move within the measurement site without carrying it, making it easy to carry and saving effort and time.

[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

A scale is installed on the second horizontal bar. The movable base has a slot corresponding to the second upright.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the first upright and the first support rod can be positioned using positioning screws, and the second upright and the second support rod can also be positioned using positioning screws, allowing the first upright and the first support rod, as well as the second upright and the second support rod, to have their lengths adjustable, thereby adjusting the distance between the contact blocks on both sides, so that the verticality measuring device can adjust the detection span as needed.

[0011] Furthermore, the positioning plate is a rectangular plate with two screw holes. The first connecting block and the second connecting block have screw grooves corresponding to the screw holes. After the positioning plate is attached to the first connecting block and the second connecting block, they can be connected by screws, so that the first connecting block and the second connecting block can be positioned.
