Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to a corrugated steel web centering measuring device. Background Technology

[0002] Corrugated steel webs are a type of high-strength steel structural component specifically designed for bridge main beams. By pressing steel plates into regular wave shapes, they possess unique mechanical properties and engineering advantages. Due to their light weight, large span capacity, and fast construction speed, they are particularly suitable for long-span bridges, bridges in areas with high seismic intensity, and bridge projects with strict construction schedule requirements.

[0003] In outdoor corrugated steel web plate installation scenarios such as bridges and elevated roads, wind conditions are uncertain due to the influence of season, time of day, and geographical location: spring is often accompanied by intermittent light winds, summer is prone to strong convective gusts, and winter is accompanied by continuous northwest winds. As the core component for centering measurement, the laser sensor is extremely sensitive to airflow disturbances. Airflow fluctuations may cause the laser beam to deviate, resulting in centering errors, which directly affect the verticality and splicing accuracy of the steel web plate installation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a corrugated steel web alignment measuring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A corrugated steel web alignment measuring device includes a base plate. A laser sensor is connected to one end of the base plate and the other end via bolts. A baffle plate is connected to one end of the base plate and the other end of the base plate. A baffle plate is connected to both ends of the base plate. Each set of baffle plates has a groove. A baffle plate is placed against each of the grooves. Each set of baffle plates has multiple holes. Some of the holes are threaded to bolts. Each set of baffle plates has a hole at one end, and the bolts are threaded to their corresponding holes. Plates are connected to all four ends of the base plate. Each plate has a groove. Clamping plates are placed against each groove. Studs are connected to one end of each clamping plate, and nuts are threaded to each stud.

[0006] Preferably, each of the multiple sets of plates has a groove three at one end and the other end, and the multiple sets of studs are respectively located in the corresponding groove three.

[0007] Preferably, both sets of grooves have sliding grooves at one end and the other end, and both sets of baffles have sliders connected to one end and the other end, with multiple sets of sliders slidably connected to the corresponding sliding grooves.

[0008] Preferably, each of the multiple sets of nuts has a washer connected to one end, and the multiple sets of washers are respectively attached to the corresponding plates.

[0009] Preferably, both sets of bolts are hexagonal socket head cap screws, and each set of bolts has a knob connected to one end.

[0010] Preferably, each of the multiple sets of grooves is connected to a rod, and the multiple sets of rods are slidably connected to the corresponding clamping plates.

[0011] Preferably, both sets of baffle one and both sets of baffle two are inclined.

[0012] The beneficial effects of this utility model are as follows: 1. Through the cooperation of the set baffles 2 and 3 and bolts 2, baffles 2 at both ends of the device's base plate are pre-set with grooves 1, and baffles 3 are embedded into the grooves 1 in a fitted manner, forming a retractable combined protective structure. When the wind force at the construction site is small, the construction personnel can push baffles 3 along the grooves 1 to retract into baffles 2, shortening the extension length of baffles 3. This adjustment method can reduce the overall space occupied by the device to a certain extent, which is suitable for construction scenarios with narrow gaps in the steel web plate installation, avoiding the problem of crowded working space caused by the excessive size of the device, and improving the flexibility of on-site construction. When encountering strong winds, baffles 3 can be pushed in the opposite direction to extend outward along the grooves 1, extending its length beyond baffles 2, thereby increasing the shielding area of ​​the laser sensor. After the baffle three is adjusted to the target extension length, the bolt two is inserted into the corresponding hole one on the baffle three and the preset hole two on the baffle two and tightened to lock the protective position of the baffle three. The fixing hole position of the bolt two can be flexibly selected according to the actual wind force to achieve step adjustment of the shielding area, ensuring that the protection strength is accurately matched with the wind force level and avoiding space waste caused by over-protection. 2. Through the engagement of the studs, nuts, and washers, when switching to measure different types of steel webs, the operator only needs to loosen the nuts to release the washer's fixation on the clamping plate. At this point, the clamping plate can slide along the pre-set rod inside the groove. The operator can then push the clamping plate along the rod to the target position according to the actual width and thickness of the steel web to be measured, until the inner side of the clamping plate is in contact with the side of the steel web. Once the clamping plate position is determined, simply retighten the nuts. The threaded locking force between the nut and the stud, combined with the increased friction from the washers, will firmly fix the clamping plate, preventing displacement due to device vibration during measurement.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1, referring to Figures 1 to 5A corrugated steel web alignment measuring device includes a base plate 1. One end of the base plate 1 and the other end are each connected to a laser sensor 3 via bolts 2. The model of the laser sensor 3 can be selected according to actual conditions. By pre-marking a point on the surface of the steel web, the laser sensor 3 emits a laser signal to detect the distance between itself and the pre-marked point in real time, thereby determining whether the device is aligned. Simultaneously, the laser sensor 3 on the other side of the base plate 1 emits a laser signal to detect the distance to a pre-marked point on the ground, determining whether the steel web is installed correctly and centered. One end of the base plate 1 and the other end are each connected to a baffle 4 to intercept and guide wind force, preventing the laser sensor 3 from being blown away. Two baffles 5 are also connected to one end of the base plate 1 to intercept and guide wind force, preventing the laser sensor 3 from being blown away. Both sets of baffles 5 have grooves 6, and two sets of grooves 6 are fitted with baffles 7. Moving the baffle 7 along the trough 16 allows adjustment of the total area of ​​the baffle 25 and the baffle 37, thus adjusting the shielding area according to the wind force. Both sets of baffle 37 have multiple sets of holes 18, some of which are threaded with bolts 29 for fixing the baffle 37. Both sets of baffle 25 have holes 210 at one end, and the two sets of bolts 29 are threaded to the corresponding holes 210. The base plate 1 has plates 13 at all four ends, and multiple sets of plates 13 have grooves 214. Multiple sets of grooves 214 have clamps 15 placed close to them, and multiple sets of clamps 15 have studs 17 connected to one end and the other end. Unscrewing the bolts 29 removes the restriction on the baffle 37, allowing the area of ​​the baffle 37 extending out of the baffle 25 to be adjusted according to the wind force, making it relatively versatile. After adjustment, screwing the bolts 29 into the holes 18 and 210 in sequence can re-fix the baffle 37.

[0017] In this embodiment, each of the multiple sets of plates 13 has a groove 16 at one end and the other end. Multiple sets of studs 17 are located within the corresponding grooves 16. Each set of studs 17 is threaded with a nut 18. By unscrewing the nuts 18 and removing the washer 19 from the groove 16, the clamping plate 15 is moved along the rod 20 until it fits against the side of the steel web. After the clamping plates 15 are all in contact with the steel web and the washer 19 is re-tightened to the groove 16, the device can be fixed to the steel web. The design of the studs 17 and nuts 18 facilitates adjusting the position of the clamping plate 15 according to the size of the steel web, thus offering a wide range of applicability. Each of the two sets of grooves 6 has a sliding groove 11 at one end and the other end. Each of the two sets of baffles 7 has a slider 12 connected to one end and the other end. Multiple sliders 12 are slidably connected to the corresponding sliding grooves 11, providing guidance for the movement of the baffles 7. Multiple sets of nuts 18 are each connected to a washer 19 at one end. These washers 19 fit snugly against their respective plates 13, increasing friction and preventing loosening due to vibration. Both sets of bolts 2 are hexagonal socket head cap screws, allowing for easy rotation with tools. Multiple sets of bolts 12 are each connected to a knob at one end, facilitating rotation. Multiple sets of grooves 24 are each connected to a rod 20, which slides along the corresponding clamping plate 15, restricting rotation and guiding movement. Both sets of baffles 14 and 25 are angled to guide airflow.

[0018] The working principle of this embodiment is as follows: In use, firstly, according to the actual width and thickness of the corrugated steel web to be measured, loosen the nut 18 matching the stud 17 on the plate 13 to release the tightness of the washer 19 against the groove 16; then push the clamping plate 15 to slide along the rod 20 in the groove 14 until the inner side of the clamping plate 15 is tightly fitted with the side of the steel web; finally, tighten the nut 18 again. Through the thread locking force of the nut 18 and the stud 17, combined with the increased friction force of the washer 19, the clamping plate 15 is firmly fixed, completing the stable connection between the device and the steel web, and avoiding displacement of the device due to vibration during the measurement process. Based on the real-time wind conditions at the construction site, adjust the protective structure composed of baffle 2 5 and baffle 3 7: if the wind is weak, push baffle 3 7 inward along the groove 1 6 of baffle 2 5, while the sliders 12 at both ends of baffle 3 7 slide along the groove 11 of the groove 1 6, shortening the extension length of baffle 3 7 to reduce the space occupied by the device; if the wind is strong, push baffle 3 7 outward along the groove 1 6 in the opposite direction, extending the protective length to increase the shielding area of ​​the laser sensor 3; after adjusting to the target position, insert bolt 2 9 into the corresponding hole 1 8 of baffle 3 7 and hole 2 10 of baffle 2 5 in sequence and tighten them, locking the position of baffle 3 7 through threaded connection, achieving precise matching between the protective strength and the wind force level, and reducing the interference of airflow on the laser sensor 3. The laser sensors 3, fixed at both ends of the base plate 1 by bolts 2, are activated. One set of laser sensors 3 emits laser signals towards preset marks on the surface of the steel web. By detecting the distance between the laser and the marks in real time, it is determined whether the device itself is aligned with the steel web. The other set of laser sensors 3 emits laser signals towards preset marks on the ground. By detecting the distance between the laser and the ground marks, it is determined whether the steel web is installed in place and centered. At the same time, the baffles 4 and 5, which are inclined at both ends of the base plate 1, cooperate to further intercept and guide the airflow, reduce the impact of wind on the stability of the laser beam, and ensure measurement accuracy. If the laser sensors 3 detect alignment deviation or installation deviation, the adjustment direction is determined according to the type of deviation: if the relative position of the device and the steel web is misaligned, the nut 18 is loosened and the clamp 15 is moved to readjust the fixed position; if the measurement deviation is caused by wind interference, the protruding area of ​​the baffle 7 is adjusted. After the adjustment is completed, the laser sensors 3 are activated again for secondary measurement and calibration until the detection data meets the alignment and installation accuracy requirements of the steel web, thus completing the entire measurement process.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
