Description

Technical Field

[0001] This utility model belongs to the field of steel structure space frame installation technology, and in particular, it is an auxiliary positioning device for steel structure space frame installation. Background Technology

[0002] In modern building construction, steel space frames are widely used due to their advantages such as high strength, lightweight, and ease of construction. However, the installation process of steel space frames often requires precise adjustment of the spacing and position between various components to ensure the stability and safety of the overall structure.

[0003] Traditional installation methods rely on workers manually measuring with tools such as rulers and tape measures, and adjusting the position of steel frame poles by pushing or pulling them. This method not only requires repeated measurements and adjustments, but also necessitates reconfirming the position after each adjustment. For example, in a large steel structure project, it may take several hours to find the appropriate spacing for the steel frame poles at each node, potentially extending the entire project's installation cycle by days or even weeks. This extended installation time leads to decreased installation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary positioning device for the installation of steel structure space frame, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary positioning device for steel structure space frame installation, comprising a steel structure space frame installation fixing plate, a handle fixed to the outer wall of the steel structure space frame installation fixing plate, a first clamping plate and a second clamping plate symmetrically arranged on the inner wall of the steel structure space frame installation fixing plate, and a relative push-pull driving component provided inside the steel structure space frame installation fixing plate, the relative push-pull driving component driving the first clamping plate and the second clamping plate to move towards the center or away from each other, so that the first clamping plate and the second clamping plate pull the first steel frame rod and the second steel frame rod closer together or push the first steel frame rod and the second steel frame rod away from each other, thereby adjusting the distance between the first steel frame rod and the second steel frame rod. The outer walls of the first steel frame rod and the second steel frame rod are longitudinally and equidistantly provided with positioning screw holes. When the first steel frame rod and the second steel frame rod are pulled closer or pushed away to adjust to the required distance, the positioning screw holes of the first steel frame rod and the second steel frame rod at the same height are locked together by locking screws.

[0006] In a preferred embodiment, both the first clamping plate and the second clamping plate have longitudinally formed arc-shaped locking grooves on their opposite inner walls, and the two arc-shaped locking grooves are respectively locked to the first steel frame rod and the second steel frame rod.

[0007] In a preferred embodiment, the relative push-pull drive component includes a positioning groove laterally opened inside the steel structure grid mounting plate, a double-ended screw rotatably installed in the positioning groove, external threaded paths symmetrically arranged on both sides of the double-ended screw with opposite thread directions, and a positioning slider with threads passing through both ends of the double-ended screw.

[0008] In this preferred embodiment, both positioning sliders slide within the positioning groove, and the external thread is threadedly connected to the positioning slider.

[0009] In a preferred embodiment of this scheme, a drive motor is fixedly installed on one side of the outer wall of the steel structure grid mounting plate, and the output shaft of the drive motor passes through the positioning slide groove and is fixedly connected to one end of the double-headed screw.

[0010] In a preferred embodiment of this design, ribs are welded to the outer walls of the opposite sides of both the first clamping plate and the second clamping plate. The outer wall of the ribs near the positioning slider makes sliding friction contact with the outer wall of the steel frame mounting plate.

[0011] In this preferred embodiment, both ends of the double-ended screw are fitted with sealed bearings with interference fit, and the inner walls of both ends of the positioning groove are provided with bearing holes for fixing and embedding the sealed bearings.

[0012] In this preferred embodiment, a detachable electrical box is embedded in the outer wall of the steel frame mounting plate on one side of the handle. A control button is provided on the outer wall of the detachable electrical box. After the locking screw locks the first steel frame rod and the second steel frame rod, it is locked by the locking nut.

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

[0014] The steel structure space frame is equipped with an auxiliary positioning device. A drive motor drives a double-ended screw, causing a positioning slider to move along a positioning groove, thereby pushing the first and second clamping plates. Because the threads at both ends of the double-ended screw are in opposite directions, the two clamping plates can move synchronously towards the center or away from each other, precisely adjusting the distance between the first and second steel frame rods. Compared to traditional manual adjustment methods, this mechanized adjustment method greatly improves adjustment speed and accuracy. Traditional methods usually require multiple attempts to find the appropriate distance, while this device allows for precise adjustment with just one button operation.

[0015] The device features a handheld handle for easy operation, allowing users to easily move it to the desired location. Furthermore, control buttons are integrated into the detachable electrical box, enabling convenient start and stop of the drive motor. This design allows for easy operation of the entire device by a single person, eliminating the need for additional human assistance and greatly simplifying the workflow for on-site construction workers. Simultaneously, its lightweight design makes the equipment easy to carry and suitable for various construction environments.

[0016] The inner walls of the first and second clamping plates are provided with arc-shaped locking grooves. These grooves fit tightly against the first and second steel frame rods, ensuring that slippage or displacement does not occur during adjustment. Furthermore, rib plates increase the strength and rigidity of the clamping plates, further enhancing the stability of the structure. This design not only improves the firmness of the clamping but also reduces errors caused by unstable clamping, ensuring that each adjustment achieves the desired effect. This is crucial for ensuring the overall stability and safety of the steel structure space frame. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] This embodiment provides, for example Figures 1 to 4 The illustrated auxiliary positioning device for steel structure space frame installation includes a steel structure space frame mounting plate 1. A handle 2 is fixed to the outer wall of the steel structure space frame mounting plate 1. A first clamping plate 3 and a second clamping plate 4 are symmetrically arranged on the inner wall of the steel structure space frame mounting plate 1. A relative push-pull driving component is provided inside the steel structure space frame mounting plate 1. The relative push-pull driving component drives the first clamping plate 3 and the second clamping plate 4 to move towards the center or away from each other, causing the first clamping plate 3 and the second clamping plate 4 to pull the first steel frame rod 5 and the second steel frame rod 6 closer together or push them apart away from each other, thereby adjusting the distance between the first steel frame rod 5 and the second steel frame rod 6. Positioning screw holes 10 are longitudinally and equidistantly opened on the outer walls of both the first steel frame rod 5 and the second steel frame rod 6. When the first steel frame rod 5 and the second steel frame rod 6 are pulled closer or pushed apart to adjust to the required distance, the positioning screw holes 10 of the first steel frame rod 5 and the second steel frame rod 6 at the same height are locked together by locking screws 7. The design of the steel frame space frame mounting plate 1, the first clamping plate 3, and the second clamping plate 4 allows for convenient installation of the steel frame space frame. When assistance is needed, the handle 2 allows the user to hold the mounting plate 1 close to the first steel frame rod 5 and the second steel frame rod 6 that need to be installed together. This engages the first clamping plate 3 and the second clamping plate 4 on the back or inner wall of the first steel frame rod 5 and the second steel frame rod 6. A push-pull drive mechanism moves the first clamping plate 3 and the second clamping plate 4 towards the center or away from each other, pulling them closer together or pushing them apart. This adjusts the distance between the first steel frame rod 5 and the second steel frame rod 6, making the installation convenient and facilitating the positioning of the steel frame space frame that needs to be installed together.

[0027] In this embodiment, both the first clamping plate 3 and the second clamping plate 4 have longitudinally formed arc-shaped locking grooves 13 on their opposite inner walls. The two arc-shaped locking grooves 13 respectively engage with the first steel frame rod 5 and the second steel frame rod 6. By designing the arc-shaped locking grooves 13, the clamping plates can fit tightly against and firmly hold the steel frame rods, ensuring that there will be no slippage or displacement during the adjustment process, enhancing clamping stability, ensuring accuracy during the adjustment process, and reducing errors.

[0028] In this embodiment, the relative push-pull drive component includes a positioning groove 19 laterally opened inside the steel structure grid mounting plate 1, a double-ended screw 14 rotatably installed in the positioning groove 19, external threaded paths 15 symmetrically arranged on both sides of the double-ended screw 14 with opposite thread directions, and positioning sliders 16 with threads passing through both ends of the double-ended screw 14. The double-ended screw 14 is rotated by the drive motor 8. Because the threads at both ends of the double-ended screw 14 are opposite in direction, the two positioning sliders 16 move in opposite directions along the positioning groove 19, thereby pushing the clamping plate. This provides a mechanized adjustment method, simplifies manual operation steps, and improves adjustment accuracy and efficiency.

[0029] In this embodiment, both positioning sliders 16 slide within the positioning grooves 19, and the external thread 15 is threadedly connected to the positioning sliders 16. When the positioning sliders 16 slide within the positioning grooves 19, they are subjected to the force of the external thread 15, ensuring smooth movement and guaranteeing the stability and accuracy of the positioning sliders 16 during the sliding process, thus avoiding deviations caused by friction.

[0030] In this embodiment, a drive motor 8 is fixedly installed on one outer wall of the steel frame mounting plate 1. The output shaft of the drive motor 8 passes through the positioning slide groove 19 and is fixedly connected to one end of the double-ended screw 14. The drive motor 8 directly drives the double-ended screw 14 to rotate through the output shaft, thereby controlling the operation of the entire adjustment system, realizing automated operation, reducing manual intervention, and improving the convenience and safety of operation.

[0031] In this embodiment, ribs 17 are welded to the outer walls of the opposite sides of the first clamping plate 3 and the second clamping plate 4. The outer wall of the rib 17 near the positioning slider 16 makes sliding friction contact with the outer wall of the steel frame mounting plate 1. The ribs 17 increase the strength and rigidity of the clamping plates, while providing additional support points, reducing the risk of deformation, enhancing the stability of the structure, extending the service life of the equipment, and ensuring reliability during long-term operation.

[0032] In this embodiment, both ends of the double-ended screw 14 are fitted with sealed bearings 18 via interference fit, and both ends of the positioning groove 19 have bearing holes 20 for the sealed bearings 18 to be fixedly embedded. The sealed bearings 18 reduce the frictional resistance of the double-ended screw 14 during rotation, improve rotational efficiency and stability, reduce wear, and improve the smoothness and durability of equipment operation.

[0033] In this embodiment, a detachable electrical box 11 is embedded in the outer wall of the steel frame mounting plate 1 on one side of the handle 2. A control button 12 is provided on the outer wall of the detachable electrical box 11. After the locking screw 7 locks the first steel frame rod 5 and the second steel frame rod 6, it is further locked by the locking nut 9. The operation of the drive motor 8 is controlled by the control button 12, facilitating user operation. The locking screw 7 and locking nut 9 ensure the fixation of the steel frame rod position, providing an intuitive and simple operating interface and improving the user experience; at the same time, it ensures the stability after installation and prevents loosening.

[0034] Working principle

[0035] The steel structure space frame is installed with an auxiliary positioning device. The first steel frame rod 5 and the second steel frame rod 6 that need to be installed together are placed in the ready position. Using the handle 2, the steel structure space frame installation fixing plate 1 is brought close to the first steel frame rod 5 and the second steel frame rod 6 that need to be installed, so that the arc-shaped snap-fit ​​groove 13 on the first clamping plate 3 and the second clamping plate 4 snaps into the first steel frame rod 5 and the second steel frame rod 6 respectively.

[0036] Operate the control button 12 to start the drive motor 8. The output shaft of the drive motor 8 will drive the double-ended screw 14 to rotate. As the double-ended screw 14 rotates, the external thread 15, which is symmetrically arranged on both sides of its periphery and has opposite thread directions, will cause the two positioning sliders 16 to move along the positioning groove 19. The positioning sliders 16 are connected to the first clamping plate 3 and the second clamping plate 4. When the positioning sliders 16 move inward or outward, the first clamping plate 3 and the second clamping plate 4 will also move inward or outward and push the first steel frame rod 5 and the second steel frame rod 6 away from each other, thereby adjusting the distance between them.

[0037] After the first steel frame rod 5 and the second steel frame rod 6 are adjusted to the required spacing, a locking screw 7 is inserted between the positioning screw holes 10 of the first steel frame rod 5 and the second steel frame rod 6 at the same height, and fixed by the locking nut 9 to ensure that the position does not change.

[0038] Turn off drive motor 8 to complete the installation of the steel structure space frame.
