Description

Technical Field

[0001] This utility model relates to the field of steel structure construction positioning and layout technology, and in particular to a detachable horizontal measurement and positioning device. Background Technology

[0002] Positioning and layout are crucial during steel structure construction, especially for steel plate walls and truss-type components, where alignment is challenging and acceptance standards are stringent. When components are installed at considerable heights, it is impossible to simultaneously meet the alignment requirements for both verticality and positioning.

[0003] During steel structure construction, the most commonly used measuring tools are reflective stickers, spirit levels, and prisms. Reflective stickers have a gel backing material that loses its adhesiveness after one or two uses, making them prone to falling off and unusable. They are especially difficult to stick to steel components after they get wet, and they are easily blown off in heavy rain or wind, requiring personnel to climb back onto the components to re-attach them, greatly increasing safety hazards. Moreover, the material is very thin and easily deformed, which increases the error when measuring large elevation angles. Ordinary spirit levels are too large to carry and have limited functionality. Prisms offer high precision, but require personnel assistance to use, and while durable, they are not easy to carry.

[0004] At this point, a detachable, horizontally oriented measurement and positioning device is needed to meet the installation and measurement needs of various types of steel components. Utility Model Content

[0005] In order to achieve the above-mentioned objectives and address the above-mentioned technical problems, this utility model provides a detachable horizontal measuring and positioning device.

[0006] The technical solution includes a square prism and two spirit levels, which are detachably connected to the two sides of the prism. Magnetic strips for attaching to steel components are fixedly installed on the outer edge of the prism, and a prism crosshair is located at the center of the prism. The spirit levels are detachable and can be removed for individual use at any time.

[0007] The thickness of the prism is 2 cm.

[0008] The level is made of iron and has a bubble level in the middle. The iron level is magnetically attached to the magnetic strip on the edge of the prism.

[0009] Two horizontal rulers are set on two adjacent sides of the prism, and scale lines are set on the other two adjacent sides of the prism.

[0010] Each of the scale lines represents a length of 1 cm, which can temporarily replace a measuring tape and can also be attached to different steel components. It only needs to be installed on the component before hoisting, and there is no need for people to climb the component to perform auxiliary measurements afterwards.

[0011] The prism panel is made of plastic.

[0012] The device features a central prism crosshair and a plastic panel, similar to a small prism in measuring tools. Its accuracy surpasses that of ordinary reflective pads. On components installed at higher heights, it effectively reflects the total station's laser, improving measurement accuracy and reducing errors. This device not only performs both positioning and verticality measurements but is also simple in material and extremely compact and portable. It can assist in measuring various types of steel components, improving accuracy and reducing errors. Furthermore, the detachable prism and two spirit levels can meet temporary on-site needs. Its simple materials and compact portability reduce measurement and calibration time, eliminate the need for manual measurement, and significantly reduce safety hazards.

[0013] The beneficial effects of the technical solution provided by this utility model embodiment are as follows: This solution provides a detachable, horizontal measurement and positioning device, which facilitates construction while ensuring personnel safety; currently common measurement auxiliary tools can no longer meet the conditions for installation and positioning at the same time. This device can not only complete measurement and positioning, but also adjust the verticality at the same time; through the magnetic connection method, it can be used on different steel components. The material is simple, portable, reusable, and durable, reducing construction costs. The detachable device can also temporarily replace the measuring tape and spirit level, thereby more effectively improving the accuracy and efficiency of construction measurement.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1 See Figures 1 to 3 This utility model provides a detachable horizontal measuring and positioning device, including a square prism 1 and two level rulers 2. The two level rulers 2 are detachably connected to the two sides of the prism 1. A magnetic strip 3 for adsorbing onto a steel component is fixedly provided on the outer edge of the prism 1, and a prism crosshair 4 is provided at the center of the prism 1. The level rulers are detachable and can be removed and used separately at any time.

[0023] The thickness of prism 1 is 2cm.

[0024] The level 2 is made of iron, and a level bubble 5 is set in the middle of the level 2; the iron level 2 is magnetically attached to the magnetic strip 3 on the edge of the prism 1.

[0025] Two horizontal rulers 2 are set on two adjacent sides of prism 1, and scale lines 6 are set on the other two adjacent sides of prism 1.

[0026] Each scale mark 6 represents 1cm in length. It can temporarily replace a measuring tape and can be attached to different steel components. It only needs to be installed on the component before hoisting, and there is no need for people to climb the component to perform auxiliary measurements afterwards.

[0027] The Prism 1 panel is made of plastic.

[0028] The device features a central prism crosshair and a plastic panel, similar to a small prism in measuring tools. Its accuracy surpasses that of ordinary reflective pads. On components installed at higher heights, it effectively reflects the total station's laser, improving measurement accuracy and reducing errors. This device not only performs both positioning and verticality measurements but is also simple in material and extremely compact and portable. It can assist in measuring various types of steel components, improving accuracy and reducing errors. Furthermore, the detachable prism and two spirit levels can meet temporary on-site needs. Its simple materials and compact portability reduce measurement and calibration time, eliminate the need for manual measurement, and significantly reduce safety hazards.

[0029] When using this utility model, the following steps are included: (1) Preparation Check the integrity of the device: Before use, check that all parts of the device are intact. Ensure that the surface of the square prism 1 is clean and free of scratches or damage, and that the prism crosshairs 4 are clearly visible; that the two spirit levels 2 are not deformed or damaged, and that the bubble level 5 is normal; that the magnetic strip 3 has normal adsorption force, and that the scale lines 6 are clearly distinguishable.

[0030] Inspect the surface of the steel components: Clean the surface of the steel components that need to be measured and positioned, removing dust, oil, rust, and other impurities to ensure that the magnet strip 3 can be firmly attached to the steel components. For steel components with water on the surface, wipe them dry first to prevent affecting the adhesion of the magnet strip.

[0031] Prepare auxiliary tools: Prepare surveying instruments such as total station, ensure they are working properly, and place the total station in a suitable position so that it can clearly illuminate the detachable leveling and positioning device.

[0032] (2) Installation device Adsorption Prism: Place one side of the magnetic strip 3 of prism 1 close to the surface of the steel component, and use the magnetic force of the magnetic strip to firmly adsorb the prism onto the steel component. Since the connection between prism 1 and the steel component is through the magnetic attraction of the magnetic strip 3, this connection method is detachable, allowing prism 1 to be reused in different locations or on different steel components. During the adsorption process, ensure that prism 1 is in close contact with the surface of the steel component to avoid loosening or tilting. If the surface of the steel component is relatively smooth, the number of magnetic strips 3 can be increased or a stronger magnetic strip can be used to ensure the stability of prism 1.

[0033] Install the spirit level: Place two iron spirit levels 2 on opposite sides of the prism 1, allowing them to magnetically attach to the magnetic strips 3 along the edge of the prism 1. The connection between the spirit levels 2 and the prism 1 is detachable; this design not only facilitates installation but also allows the spirit levels 2 to be removed separately for other measurement tasks when needed. During installation, pay attention to the position of the level bubble 5 on the spirit levels 2 to ensure they are level. If the spirit levels 2 are not level, adjust the position of the prism 1 on the steel component or make minor adjustments to the steel component to achieve a level position.

[0034] Check the installation: After installation, check the entire device installation again. Observe whether prism 1 is firmly attached to the steel component, whether the spirit level 2 is tightly attached to prism 1 and is horizontal, and whether the scale line 6 is clearly visible. If there are any problems, adjust them in time to ensure that the device can work normally.

[0035] (3) Perform measurement and positioning Positioning Measurement: A total station is used to illuminate the detachable horizontal positioning device mounted on the steel component. The positioning coordinates of the steel component are determined by observing the total station readings and the position of the prism crosshairs 4. Prism crosshairs 4 provide precise reflection points, improving the accuracy of the total station measurement and reducing measurement errors. During the measurement process, it is essential to ensure a clear line of sight between the total station and the detachable horizontal positioning device, avoiding obstructions from other objects that could affect the measurement results. Due to the detachable nature of the device, if it is necessary to change the measurement position or adjust the device during the measurement process, it can be easily disassembled and reinstalled without affecting the continuity of the measurement work.

[0036] Verticality Measurement: Verticality is measured using two level rulers (2). Observe the position of the horizontal bubble (5) on the level rulers (2). If the horizontal bubble (5) is in the center, the steel component is vertically correct in that direction. If the horizontal bubble (5) deviates from the center, the steel component is tilted and needs adjustment until the horizontal bubble (5) returns to the center position. For steel components requiring verticality measurements in multiple directions, the level rulers (2) can be detached and reinstalled on other sides for measurement. This detachable design makes the measurement work more flexible and can meet different measurement needs. Ensure that the verticality of the steel component meets the requirements in all directions.

[0037] Example 2 Based on Example 1, situations may arise at steel structure construction sites where a measuring tape or ruler is temporarily unavailable. In such cases, the scale lines 6 on the detachable horizontal measuring and positioning device can play a crucial role, providing a convenient temporary measurement method.

[0038] Align one end of the object or component to be measured with the zero point of scale line 6. Ensure alignment accuracy to avoid measurement errors caused by inaccurate alignment.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
