Description

Technical Field

[0001] This utility model belongs to the field of engineering surveying technology, specifically relating to a surveying device for civil engineering management. Background Technology

[0002] In civil engineering management, surveying is a core component for ensuring construction quality, controlling project progress, and guaranteeing structural safety. Traditional surveying techniques mainly rely on manual operation of optical instruments (such as theodolites and levels) or laser rangefinders. In large-scale construction sites, to ensure construction quality and the reliability of support structures, it is necessary to measure the verticality of walls, the verticality of scaffolding steel pipe connections, and the verticality of scaffolding vertical steel pipes. Traditional electronic surveying instruments such as levels are complex to operate, require training, and are expensive, making them difficult to widely equip construction workers with. Often, specialized surveyors are needed to carry and measure them. However, in construction sites, there are numerous measurement points for scaffolding and building walls, and the measurement speed of specialized personnel carrying electronic surveying instruments is limited, making it difficult to meet the needs of rapid construction in modern engineering. Therefore, this application proposes a surveying device for civil engineering management. Utility Model Content

[0012] Beneficial effects

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes the vertical arrangement of a first and second measuring arm, along with the placement of positioning forks and a spirit level. A pair of positioning forks are flipped to the side of the first and second measuring arms that are far apart from each other, and are positioned by the cooperation of a positioning component and a second connecting block. The first and second measuring arms are placed at the connection point of two steel pipes of the scaffolding. The pair of positioning forks are respectively clamped onto the two steel pipes.

[0023] 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.

[0024] This embodiment provides a measuring device for civil engineering management, the structural diagram of which is shown below. Figures 1-5 As shown, it includes a first measuring arm 1 and a second measuring arm 2, which are distributed at right angles and connected as one unit. A level bubble 4 is set on the facing side of the first measuring arm 1 and the second measuring arm 2. By utilizing the vertical distribution of the first measuring arm 1 and the second measuring arm 2, the first measuring arm 1 and the second measuring arm 2 are placed at the connection of two steel pipes of the scaffold or at the corner of the building wall during the construction process. With the help of the level bubble 4, it is possible to intuitively measure and judge whether the two steel pipes of the scaffold are vertically connected or horizontally erected, and at the same time, it is possible to intuitively judge the verticality of the building wall.

[0025] In a further embodiment, positioning forks 3 are provided on the opposite sides of the first measuring arm 1 and the second measuring arm 2. The positioning forks 3 can be flipped and retracted towards the opposite side of the first measuring arm 1 and the second measuring arm 2. The positioning forks 3 are U-shaped and nested with the scaffold steel pipes. The closed end of the positioning fork 3 has a flat boss that can fit against the surface of the first measuring arm 1. After the positioning fork 3 flips to the opposite side of the first measuring arm 1 and the second measuring arm 2, the internal cavity of the positioning fork 3 maintains a translational length direction with the first measuring arm 1 or the second measuring arm 2. With this structure, the pair of positioning forks 3 flip to the opposite side of the first measuring arm 1 and the second measuring arm 2, with the first measuring arm 1 and the second measuring arm 2 positioned at the connection point of the two scaffold steel pipes. The pair of positioning forks 3 are respectively clamped onto the two steel pipes. By observing whether the pair of positioning forks 3 can simultaneously and tightly clamp onto the two steel pipes, it is possible to visually determine whether the two steel pipes are vertically connected. The verticality of the two scaffold steel pipes can be measured by observing the level bubble 4 on the first measuring arm 1 or the second measuring arm 2. This device can intuitively determine whether the scaffolding steel pipes are horizontally erected, thus enabling measurement and management of the reliability of scaffolding construction. One positioning fork 3 is flipped to face the first measuring arm 1 and the second measuring arm 2, while the other positioning fork 3 is clamped onto the vertical steel pipe of the scaffolding. The second measuring arm 2 rests on the ground. By observing the level bubble 4 on the second measuring arm 2, it is possible to intuitively determine whether the scaffolding steel pipes are vertically erected on the ground. This can be used to measure whether the vertical steel pipes of the scaffolding are vertically erected on the ground. Alternatively, both positioning forks 3 can be flipped to face the first measuring arm 1 and the second measuring arm 2, with the first and second measuring arms 1 and 2 placed at the bottom of the building wall. Combined with the level bubble 4, this device can be used to measure the verticality of the building wall. Because this measuring device uses the mechanical structure of the first measuring arm 1, the second measuring arm 2, and the positioning fork 3, as well as the physical measurement principle of the level bubble 4, compared to traditional electronic measuring equipment such as levels, it has a simple structure, low cost, is easy to carry and operate, and can be mass-produced for engineering personnel, thus facilitating the management of construction quality.

[0026] In this embodiment, a fixing rod 5 connects the facing surfaces of the first measuring arm 1 and the second measuring arm 2. The fixing rod 5 reinforces the first measuring arm 1 and the second measuring arm 2. A rubber sleeve 6 is fitted onto the fixing rod 5 for easy hand operation. An outer corner protector 17 is provided at the connection point of the first measuring arm 1 and the second measuring arm 2 to provide wear resistance. The corner protector 17 can be replaced individually, extending the overall service life. A raised ridge 18 is provided at the inner corner of the connection point of the first measuring arm 1 and the second measuring arm 2 for reinforcement.

[0027] In a further embodiment, a first connecting block 8 is provided on the positioning fork 3. The first connecting block 8 is disposed on the planar boss of the positioning fork 3. The ends of the first measuring arm 1 and the second measuring arm 2 are provided with connecting grooves 7. The first connecting block 8 is rotatably installed in the connecting grooves 7 to realize the flipping and retraction of the positioning fork 3. A second connecting block 9 is also provided on the planar boss of the positioning fork 3. A pair of second connecting blocks 9 are symmetrically arranged with the first connecting block 8 as the center. The second connecting blocks 9 can be embedded in the connecting grooves 7. An assembly hole 10 is provided at the position where the ends of the first measuring arm 1 and the second measuring arm 2 are aligned with the connecting grooves 7. A positioning member 11 for preventing the second connecting block 9 from falling out of the connecting grooves 7 is installed in the assembly hole 10. Specifically, the positioning member 11 includes an end cap 12 threaded in the assembly hole 10 and a part passing through the end cap. The pull rod 13 on the 12 and the pin 14 fixed at the end of the pull rod 13 facing the inside of the assembly hole 10. The pin 14 extends into the connecting groove 7. The second connecting block 9 has a positioning hole 19 that engages with the pin 14. A spring 15 is provided between the pin 14 and the end cap 12. The end of the pull rod 13 located outside the assembly hole 10 is provided with an end block 16. When the positioning fork 3 is flipped to the point where the first measuring arm 1 and the second measuring arm 2 are away from each other or facing each other, one of the second connecting blocks 9 is embedded in the connecting groove 7. The spring 15 pushes the pin 14 to insert into the positioning hole 19 on the second connecting block 9, which can prevent the second connecting block 9 from coming out of the connecting groove 7 and position the positioning fork 3. By holding the end block 16 and pulling the pull rod 13, the pin 14 is disengaged from the positioning hole 19, and the positioning fork 3 can be flipped.

[0028] Working principle: When measuring the verticality of two steel pipes of scaffolding, the positioning fork 3 is flipped so that the first measuring arm 1 and the second measuring arm 2 are far apart. The corresponding second connecting block 9 on the positioning fork 3 is embedded in the connecting groove 7. The spring 15 pushes the pin 14 into the positioning hole 19 on the second connecting block 9, preventing the second connecting block 9 from coming out of the connecting groove 7 and positioning the positioning fork 3. At this time, the first measuring arm 1 and the second measuring arm 2 are placed at the connection point of the two steel pipes of the scaffolding by holding the fixing rod 5. The pair of positioning forks 3 are respectively clamped against the two steel pipes. Since the first measuring arm 1 and the second measuring arm 2 are vertically distributed, it can be intuitively judged whether the two steel pipes are vertically connected by observing whether the pair of positioning forks 3 can be tightly clamped with the two steel pipes at the same time. At the same time, the level bubble 4 on the first measuring arm 1 or the second measuring arm 2 can be observed. This allows for a direct assessment of whether the scaffolding steel pipes are horizontally erected, thus aiding in quality management of the reliability of scaffolding construction. Furthermore, when it is necessary to measure whether the vertical steel pipes of the scaffolding are vertically erected on the ground, one of the positioning forks 3 is flipped to face the first measuring arm 1 and the second measuring arm 2 (taking the positioning fork 3 on the second measuring arm 2 as an example). Then, the positioning fork 3 on the first measuring arm 1 is pressed tightly against the vertical steel pipe of the scaffolding, while the second measuring arm 2 rests against the ground. By observing the level bubble 4 on the second measuring arm 2, it is possible to directly assess whether the scaffolding steel pipes are vertically erected on the ground. Furthermore, both positioning forks 3 can be flipped to face the first measuring arm 1 and the second measuring arm 2. At this time, the first measuring arm 1 and the second measuring arm 2, together with the level bubble 4, can be used to measure the verticality of the building walls. With a reasonable overall structure, it can be used to measure the verticality of scaffolding steel pipes as well as the verticality of building walls. Compared with the traditional method of measuring with electronic equipment such as levels, it has a simple structure, low cost, and is easy to carry and operate. It is suitable for mass deployment by engineering personnel and indirectly ensures project quality.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
