Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure truss construction technology, and more specifically, to a dimensional measuring device for the installation of steel connecting corridors. Background Technology
[0002] In steel truss construction, the installation of diagonal braces is a crucial step in ensuring the overall structural stability and precision. Traditional installation methods typically involve phased operations, such as first installing vertical braces and correcting their verticality, then sequentially installing diagonal braces, horizontal braces, and diagonal braces, and finally performing overall alignment and welding. The specific process includes jig installation, measurement and correction, chord positioning, and installation of vertical members and diagonal tie rods (including diagonal braces).
[0003] The installation of diagonal web members typically proceeds from the center outwards, relying on temporary supports, hoisting lugs, and a two-point lifting process. During installation, the position of the outer chord members needs to be adjusted to position the diagonal web members, followed by repositioning the chord members and spot welding them in place. Measurements are performed using a plumb bob and a total station for accuracy control. Additionally, sections need to be reserved at the segment locations for later installation; the diagonal web members are then installed after the upper and lower chords are joined, with temporary reinforcement measures used if necessary.
[0004] To improve installation accuracy, existing technologies employ three-dimensional layout and hoisting point simulation to optimize the positioning of the diagonal bracing, and adjust the hoisting angle using specialized welding lugs and wire ropes. For dimensional control, they rely on staged correction (such as main beam deflection, spacing measurement, and correction) and pre-camber technology, combined with jacking devices to suppress welding deformation. However, existing methods still suffer from problems such as complex procedures, high demand for temporary supports, and low correction efficiency. Utility Model Content
[0005] The purpose of this utility model is to provide a dimension measuring device for the installation of steel connecting corridors, which addresses the shortcomings of existing technologies and solves the problems mentioned in the background.
[0006] The technical solution of this utility model is implemented as follows:
[0007] This utility model provides a dimension measuring device for the installation of a steel connecting corridor, including a reference base. A fixing mechanism is installed at the bottom of the reference base to fix it to the steel connecting corridor. A transverse sliding structure is installed between the fixing mechanism and the reference base. The transverse sliding structure is used to push the reference base to move along the extension direction of the steel connecting corridor. A reference measuring arm is rotatably installed on the top of the reference base. An adjustment mechanism is provided on the reference base to control the rotation of the reference measuring arm. Lifting arms are installed at both ends of the reference measuring arm. A locking mechanism for fixing the diagonal bracing is installed on the lifting arms.
[0008] In some technical solutions of this utility model, the adjustment mechanism includes an angle measuring plate, which is installed on the side wall of the reference base. A rotating shaft is installed on the side wall of the angle measuring plate. A reference measuring arm is rotatably mounted on the rotating shaft. A locking hole is opened on the side wall of the reference measuring arm. A locking rod passes through the locking hole. Several limiting holes are opened around the outer side wall of the rotating shaft. A blocking spring connected to the inner wall of the locking hole is sleeved on the side wall of the locking rod.
[0009] In some technical solutions of this utility model, the fixing mechanism includes a fixing frame installed at the bottom of the reference base. A rectangular limiting groove is opened on the side wall of the fixing frame. A limiting plate is installed in the limiting groove. A guide rod is installed on the side wall of the limiting plate. The guide rod passes through the fixing frame and extends outward. A limiting spring connected to the fixing frame is installed on the extended end of the guide rod.
[0010] In some technical solutions of this utility model, the number of fixing mechanisms is two sets.
[0011] In some technical solutions of this utility model, the transverse structure includes a transverse frame, a guide groove is provided on the side wall of the transverse frame, a displacement block connected to the reference seat is slidably provided in the guide groove, and the fixing frame in the fixing mechanism is connected to the transverse frame.
[0012] In some technical solutions of this utility model, the fixing mechanism includes a fixing seat, which is connected to the lifting arm. A groove is provided on the side wall of the fixing seat, and a first electromagnetic lock is installed in the groove.
[0013] In some technical solutions of this utility model, a first push rod is installed inside the lifting arm, and the telescopic end of the first push rod is connected to the fixed base.
[0014] In some technical solutions of this utility model, a second electromagnetic lock is installed inside the displacement block, and a connecting plate magnetically connected to the second electromagnetic lock is installed inside the guide groove.
[0015] Compared with existing technologies, this utility model has at least the following advantages or beneficial effects: The reference base and fixing mechanism rely on the steel connecting corridor body as the reference surface, ensuring the rigid transmission of the measurement reference, eliminating external environmental interference, and significantly improving the installation accuracy of structural components. The symmetrically arranged double fixing mechanism design balances the torque, reduces offset errors during the measurement process, and enhances overall stability. The disc angle measuring plate and locking device in the adjustment mechanism support relatively precise angle adjustment and quick locking, avoiding measurement arm offset caused by vibration or external force, and ensuring that the horizontal height of both ends of the inclined web is consistent; the transverse structure realizes stepless movement and quick locking of the reference base along the extension direction of the steel connecting corridor through the second electromagnetic lock and connecting plate, covering the needs of large-area continuous measurement and reducing the time for repeated positioning. The limiting plate in the fixing mechanism, together with the limiting spring and guide rod, forms a two-way elastic clamp, automatically adapting to the size differences of different parts of the steel connecting corridor, realizing rapid installation and reliable fixing. The first push rod adjusts the horizontal height of the lifting arm supporting the structural components, and works with the first electromagnetic lock to quickly lock the inclined web, reducing manual intervention and improving alignment efficiency.

[0024] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0025] Example
[0026] This utility model provides a dimensional measuring device for the installation of steel connecting corridors, such as... Figures 1-6 As shown, the structure includes a reference base 2, which is a steel frame structure to extend the service life of the structure. A fixing mechanism is installed at the bottom of the reference base 2 to secure it to the steel connecting corridor. This fixing mechanism allows the structure to be fixed to the main body of the steel connecting corridor, using the corridor as a reference for installing other structural components within the corridor, ensuring the installation accuracy of the structural components during assembly. A transverse sliding structure is installed between the fixing mechanism and the reference base 2. This structure pushes the reference base 2 to move along the extension direction of the steel connecting corridor, increasing the coverage area of the structure and enabling continuous measurement. A reference measuring arm 3 is rotatably mounted on the top of the reference base 2. The reference measuring arm 3 is a steel frame structure, which is not easily deformed during use. This ensures that when the structure supports the diagonal bracing or other structural components, the horizontal height of the two ends of the diagonal bracing will not fluctuate, preventing the installation of the diagonal bracing from failing to achieve the specified installation accuracy. The reference base 2 is equipped with an adjustment mechanism to control the rotation of the reference measuring arm 3. Support arms 5 are installed at both ends of the reference measuring arm 3, and locking mechanisms for fixing the diagonal bracing are installed on the support arms 5. The locking mechanism is used to fix the diagonal brace to the two lifting arms 5 to prevent the diagonal brace from moving laterally when its installation angle is adjusted or measured by the reference measuring arm 3, which would prevent the diagonal brace from being assembled into the preset position.
[0027] In some technical solutions of this utility model, the adjustment mechanism includes an angle measuring plate 13. The measuring plate is disc-shaped, and its surface is engraved with 360° circumferentially arranged measuring marks, which facilitates manual adjustment and observation of the rotation angle of the reference measuring arm 3, adapts to different installation angles of the inclined web members, and improves the installation accuracy during the installation process of the inclined web members. The angle measuring plate 13 is fixedly installed on the side wall of the reference base 2 by bolts. A rotating shaft 4 is installed on the side wall of the angle measuring plate 13, and the rotation center of the rotating shaft 4 is coaxial with the center of the circle on which the angle measuring plate 13 is located. The reference measuring arm 3 is rotatably mounted on the rotating shaft 4. A locking hole is opened on the side wall of the reference measuring arm 3, and a locking rod 11 passes through the locking hole. The end face of the locking rod has a locking bevel. Several limiting holes are arranged around the outer wall of the rotating shaft 4. A stop spring 14 connected to the inner wall of the locking hole is fitted on the side wall of the locking rod 11. The stop spring 14 enables the locking rod 11 to be quickly locked on the rotating shaft 4, ensuring that the reference measuring arm 3 works stably at a fixed angle and avoiding displacement due to vibration or external force during measurement. Furthermore, the cooperation between the stop spring 14 and the locking rod 11 can improve the flexibility and stability of the angle adjustment of the reference measuring arm 3 in this structure and simplify the operation process.
[0028] In some technical solutions of this utility model, the fixing mechanism includes a fixing frame 1 bolted to the bottom of the reference base 2. A rectangular limiting groove is formed on the side wall of the fixing frame 1. The fixing frame 1 has a U-shaped frame structure. A limiting plate 15 is installed in the limiting groove. The side wall of the limiting plate 15 has raised and recessed scratches to increase the friction between the limiting plate 15 and the steel connecting corridor. Guide rods 10 are installed on the side walls of the limiting plate 15. The guide rods 10 extend outwards after passing through the fixing frame 1, and a limiting spring 16 connected to the fixing frame 1 is installed on the extended end of the guide rod 10. The elastic extension and contraction of the limiting spring 16 forces the guide rod 10 to reciprocate on the fixing frame 1 to adapt to the dimensional differences of different parts of the steel connecting corridor, enhancing the versatility of the device. The limiting plate 15 and the guide rod 10 provide bidirectional clamping force in cooperation with the limiting spring 16, ensuring a rigid connection between the reference base 2 and the steel connecting corridor and avoiding displacement errors during measurement. It enables rapid installation and reliable fixation, adapting to complex working conditions.
[0029] In some technical solutions of this utility model, the number of fixing mechanisms is two sets. The symmetrically distributed fixing mechanisms enhance the overall stability of the reference base 2, balance the torque generated during the measurement process, reduce errors, and improve the stability of the structure in fixing the reference base 2 to the steel connecting corridor.
[0030] In some technical solutions of this utility model, the lateral movement structure includes a lateral movement frame 8, a guide groove 9 is provided on the side wall of the lateral movement frame 8, and a displacement block 17 connected to the reference seat 2 is slidably disposed in the guide groove 9. The fixing frame 1 in the fixing mechanism is connected to the lateral movement frame 8. A second electromagnetic lock is installed in the displacement block 17, and a connecting plate magnetically connected to the second electromagnetic lock is installed in the guide groove 9. The reference seat 2 is slidably disposed in the guide groove 9 via the displacement block 17. When the operator pushes the reference seat 2 to move precisely along the extension direction of the steel corridor, it covers the continuous measurement requirements. The second electromagnetic lock and the connecting plate fix the displacement block 17 by electromagnetic adsorption, simplifying the lateral position locking operation and improving adjustment efficiency. The above structure can expand the measurement range and reduce the need for manual repetitive positioning.
[0031] In some technical solutions of this utility model, the fixing mechanism includes a fixing seat 6, which is connected to the lifting arm 5. A groove 7 is provided on the side wall of the fixing seat 6. A first electromagnetic fixing seat 6 and a first electromagnetic lock are installed in the groove 7. The electromagnetic locking force is used to quickly clamp the inclined web bar, reduce manual intervention, and improve fixing efficiency.
[0032] In some technical solutions of this utility model, a first push rod 12 is installed inside the lifting arm 5, and the telescopic end of the first push rod 12 is connected to the fixed seat 6. The first push rod 12 controls the fixed seat 6 to move up and down in the vertical direction, and can finely adjust the horizontal height of the fixed seat 6 to ensure the precise alignment of the inclined web member.
[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
