Description

Technical Field

[0001] This invention relates to the field of building metal roof trusses, specifically to a safe construction device for large-span hyperbolic metal roof trusses and its construction simulation method. Background Technology

[0002] A metal roof truss is a building structure made of metal materials, primarily used to support the weight of the roof and withstand wind loads acting on the upper chord. Metal roof trusses are typically composed of members made of various steel profiles, steel pipes, or steel plates, such as angle steel, channel steel, I-beams, and H-beams. These members are assembled together by welding, bolting, or riveting to form a stable structural system. Steel roof trusses are the most common type of metal roof truss, offering advantages such as high strength, light weight, and fast construction speed. Steel roof trusses can be designed in various shapes and spans to meet different architectural needs, such as triangular, trapezoidal, and arched shapes. They are widely used in large-span buildings such as industrial plants, commercial buildings, stadiums, and exhibition halls.

[0003] According to a patent application (publication number: CN215928931U), a BIM-based construction simulation device is disclosed. In this simulation device, a lifting platform is fixedly connected to a fixing component, and four monitors are fixedly connected to each of the four sides of the fixing component. This is because most construction simulation devices only have one monitor, which is insufficient for construction workers to view the site from all angles. By fixing monitors to each of the four sides of the fixing component, construction workers do not need to be in one location to view the site simultaneously, thus saving their time.

[0004] While the aforementioned existing technologies can achieve this through their structures, they still suffer from the following drawbacks: In practical application scenarios, although the device can meet basic multi-directional viewing needs, it cannot deeply integrate virtual information with real construction scenarios, resulting in the lack of information overlay and interactive functions during the construction process; in addition, existing technologies only support planar perspective presentation and lack an immersive viewing experience in three-dimensional space, resulting in problems such as insufficient scene adaptability and limited practical value in actual use, thus having poor practicality.

[0005] To address the aforementioned issues, a safe construction device for large-span hyperbolic metal roof trusses and its construction simulation method are proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a safe construction device for large-span hyperbolic metal roof trusses and its construction simulation method, solving the following technical problems: In practical application scenarios, although the existing technology can meet the basic multi-directional viewing needs, it cannot deeply integrate virtual information with the real construction scene, resulting in the lack of information overlay and interactive functions during the construction process; in addition, the existing technology only supports planar perspective presentation and lacks an immersive viewing experience in three-dimensional space, resulting in insufficient scene adaptability and limited practical value in actual use, thus its practicality is poor.

[0007] The objective of this invention can be achieved through the following technical solutions: A safe construction device for a large-span hyperbolic metal roof truss includes an installation frame, a heat dissipation mechanism, a stabilization mechanism, a movable mechanism, and an anti-slip placement mechanism. The installation frame is equipped with a scene simulation mechanism. The scene simulation mechanism includes a mounting slot inside a mounting frame. A first mounting frame is located inside the mounting slot. A mounting plate is fixedly connected inside the first mounting frame. A rubber pad is fixedly connected to the upper side of the mounting plate. A first display is located above the rubber pad. A transparent glass plate is located inside the mounting frame. A rubber frame is located above the transparent glass plate. A model frame is fixedly connected to the upper side of the rubber frame. A QR code slot is provided on the surface of the model frame. Three-dimensional simulation mechanisms are located on both sides of the mounting frame. Each three-dimensional simulation mechanism includes a connecting frame fixedly connected to both sides of the mounting frame. A second mounting frame is fixedly connected to one end of each connecting frame. A slot is provided inside the second mounting frame. A second display is secured inside the slot. An acrylic plate tower is fixedly connected to the lower side of the second display.

[0008] As a further aspect of the present invention: the first mounting bracket is slidably connected to the mounting groove, and the transparent glass plate is disposed on the upper side of the first display.

[0009] As a further aspect of the present invention: the heat dissipation mechanism includes a slot formed on the lower surface of the mounting bracket, and a heat dissipation groove is formed on the lower surface of the first mounting bracket, and the slot is connected to the heat dissipation groove.

[0010] As a further aspect of the present invention: the stabilizing mechanism includes a first magnet fixedly connected to the inside of the mounting groove, a second magnet fixedly connected to one side of the first mounting frame, and a first handle symmetrically fixedly connected to the other side of the first mounting frame.

[0011] As a further aspect of the present invention: a second handle is symmetrically fixedly connected to the middle of one side of the connecting frame for assisting in the movement of the device.

[0012] As a further aspect of the present invention: the movable mechanism includes a base fixedly connected to both sides of the mounting frame, the base having a hidden groove inside, an electric push rod fixedly installed inside the hidden groove, and multiple casters rotatably connected to the lower side of the electric push rod.

[0013] As a further aspect of the present invention: the anti-slip placement mechanism includes an anti-slip pad fixedly connected to the lower side of the base, and the lower surface of the anti-slip pad is provided with a plurality of anti-slip grooves.

[0014] As a further aspect of the present invention, the anti-slip pad is a rubber layer.

[0015] This invention also discloses a construction simulation method for a safe construction device for a large-span hyperbolic metal roof truss, specifically including the following steps: S1, Device setup phase; During equipment installation, the worker holds the first handle, aligns the first mounting bracket with the mounting slot, and slides it in. At this time, the second magnet on one side of the first mounting bracket attracts and adheres tightly to the first magnet inside the mounting slot, fixing the first display in place. Next, the second display is aligned with the slot of the second mounting bracket, placed in smoothly, and ensured to be securely installed. A scaled-down model of the actual roof truss is placed on the model frame to simulate the real construction scene. When the device needs to be moved, the worker holds the second handle in the middle of one side of the connecting bracket and operates the electric push rod hidden in the slot inside the base. When the electric push rod extends or retracts, it drives the casters to extend from the base and contact the ground, then pushes the device to move. After reaching the designated position, the electric push rod retracts, and the casters are hidden. S2, Three-dimensional simulation operation phase; The first display is activated to show the 3D model of the large-span hyperbolic metal roof truss constructed using BIM technology, while also displaying the construction schedule and material information. The second display is activated, which, together with the acrylic panel tower, shows the structural details and connection methods of the roof truss from different angles, providing a 3D immersive viewing experience. S3, Scene simulation and virtual-real fusion; Staff use equipment to scan the QR code in the QR code slot to associate with AR animation. AR technology is based on BIM data and overlays virtual construction processes and safety precautions, such as high-altitude operation protection and welding operation specifications, onto the physical model. Construction workers observe the content on the screen below through the transparent glass plate above the first display, and at the same time obtain information in conjunction with the physical model above, forming an intuitive virtual and real combination display. S4. Heat dissipation and stable operation are guaranteed; During the entire operation of the equipment, the heat generated by the first display during operation will be dissipated to the outside of the device in a timely manner through the heat dissipation slot and the opening slot. During operation, the first display needs to be adjusted. The construction personnel hold the first handle and push or pull the first mounting bracket to make it slide along the mounting slot.

[0016] The beneficial effects of this invention are: (1) The present invention provides a safety construction device for a large-span hyperbolic metal roof truss and its construction simulation method. AR technology uses a QR code slot as the trigger point. When the QR code is scanned, the system accurately superimposes the virtual construction information in the BIM model, such as the construction process of each stage and the technical parameters of key nodes, onto the physical model of the model frame in the form of a three-dimensional image. Construction personnel can intuitively see the specific location and operation method of the virtual construction steps in the physical scene, realize the deep interaction and integration of virtual information and real construction scene, and make up for the defects of information superposition in traditional devices. (2) The present invention provides a safe construction device and construction simulation method for a large-span hyperbolic metal roof truss. This device utilizes a two-dimensional simulation mechanism composed of a second display on both sides of the mounting frame and an acrylic plate tower to display the structural details of the roof truss from multiple angles, such as the internal structure of complex nodes and the formation process of curved surfaces. Combined with the virtual-real display of the first display and the model frame, construction personnel can observe the roof truss model from all angles, no longer limited to a planar perspective, significantly improving the immersive experience and scene adaptability of the viewing experience, and solving the problem of poor practicality of traditional devices.

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] In the field of building metal roof truss technology, existing technologies for safe construction devices for large-span hyperbolic metal roof trusses, while meeting basic multi-directional viewing needs in practical applications, cannot deeply integrate virtual information with the real construction scene, resulting in a lack of information overlay and interactive functions during construction. Furthermore, existing technologies only support planar perspectives, lacking an immersive three-dimensional viewing experience, leading to insufficient scene adaptability and limited practical value in actual use. To address these issues with traditional construction techniques, this invention utilizes innovative structural design to achieve deep interaction and integration between virtual information and the real construction scene, overcoming the shortcomings of traditional devices in information overlay.

[0024] like Figures 1 to 5As shown, this application embodiment provides a safe construction device for a large-span hyperbolic metal roof truss, including a mounting frame 1, a heat dissipation mechanism, a stabilization mechanism, a movable mechanism, and an anti-slip placement mechanism. The mounting frame 1 is equipped with a scene simulation mechanism, which includes a mounting groove 101. A first mounting frame 102 is provided inside the mounting groove 101. A mounting plate 103 is fixedly connected inside the first mounting frame 102. A rubber pad 104 is fixedly connected to the upper side of the mounting plate 103. A first display 105 is placed on the upper side of the rubber pad 104. A transparent glass plate 106 is opened inside the mounting frame 1. A rubber frame 107 is placed on the upper side of the transparent glass plate 106. A model frame 108 is fixedly connected to the upper side of the rubber frame 107. A QR code groove 109 is opened on the surface of the model frame 108. The mounting frame 1 has a three-dimensional simulation mechanism on both sides. The three-dimensional simulation mechanism includes a connecting frame 201. One end of the connecting frame 201 is fixedly connected to a second mounting frame 202. The second mounting frame 202 has a slot 203 inside. The slot 203 holds a second display 204. An acrylic plate tower 205 is fixedly connected to the lower side of the second display 204. The first mounting frame 102 is slidably connected to the mounting groove 101. A transparent glass plate 106 is located on the upper side of the first display 105. The mounting groove 101 is opened inside the mounting frame 1. The connecting frame 201 is fixedly connected to both sides of the mounting frame 1. The device consists of multiple parts such as the mounting frame 1 and the heat dissipation mechanism.

[0025] In the scene simulation mechanism, the first mounting frame 102 is slidably connected to the mounting slot 101, facilitating the disassembly and assembly of the first display 105. The first display 105 shows the 3D model of the metal roof truss constructed using BIM technology, construction schedule planning, material information, and other content. The model frame 108 holds a scaled-down physical roof truss model. The QR code in the QR code slot 109 is associated with AR animation. When staff scan the QR code, AR technology, based on BIM data, accurately overlays virtual construction processes and safety precautions, such as high-altitude operation protection and welding operation specifications, onto the physical model, achieving a deep integration of virtual information and the real construction scene. The transparent glass plate 106 is located above the first display 105, allowing construction personnel to observe the content on the screen below through it, while simultaneously combining it with the physical model above to form an intuitive display combining virtual and real elements. In the three-dimensional simulation mechanism, the second display 204 is installed in the second mounting frame 202 through the slot 203. Together with the acrylic plate tower 205, it displays the structural details and connection methods of the roof truss from different angles, making up for the shortcomings of the traditional planar perspective and providing a three-dimensional immersive viewing experience. This solves the problems of information fusion and perspective experience in the background technology.

[0026] like Figure 2 , Figure 5As shown, in one aspect of this embodiment, the heat dissipation groove 302 of the heat dissipation mechanism is formed on the lower surface of the first mounting frame 102, and the groove 301 is located on the lower surface of the mounting frame 1, and the two are in communication with each other. The first display 105 generates heat during operation. The heat can be dissipated to the outside of the device in a timely manner through the heat dissipation slot 302 and the opening slot 301, which effectively prevents the performance of the first display 105 from deteriorating due to overheating and ensures the stability and smoothness of BIM+AR simulation display.

[0027] like Figure 4 , Figure 5 In one aspect of this embodiment, in the stabilizing mechanism, when the first mounting frame 102 slides into the mounting groove 101, the second magnet 402 on one side of the first mounting frame 102 attracts and adheres tightly to the first magnet 401 on the inner side of the mounting groove 101, thereby firmly fixing the first mounting frame 102 in the mounting groove 101, preventing the first display 105 from shaking or shifting during device movement and use, ensuring that the BIM+AR simulation image is always stably presented, and the first handle 403 makes it easy for construction personnel to push and pull the first mounting frame 102, making operation convenient.

[0028] like Figure 1 , Figure 3 As shown, in one aspect of this embodiment, a second handle 501 located in the middle of one side of the connecting frame 201 can be gripped by construction personnel to assist in moving the device or adjusting its position. An electric push rod 603 is installed in a hidden groove 602 inside the base 601 of the mobile mechanism. When the electric push rod 603 extends or retracts, it can drive the caster wheel 604 to extend or retract from the base 601. When the device needs to be moved, the electric push rod 603 extends, the caster wheel 604 contacts the ground, and the device can move flexibly; after reaching the designated position, the electric push rod 603 retracts, and the caster wheel 604 is hidden.

[0029] As shown in the figure, and Figure 2 As shown, in one aspect of this embodiment, the anti-slip pad 701 on the lower side of the base 601 is in contact with the ground. The anti-slip pad 701 is made of rubber, and the anti-slip groove 702 on its lower surface increases the friction with the ground, prevents the device from sliding, ensures that the device is placed stably, and meets the usage requirements of different construction sites.

[0030] In this plan, all electrical equipment is connected to an external power source and powered by the external power source to ensure the normal operation of the electrical equipment.

[0031] The working principle of this invention is as follows: A safe construction device and construction simulation method for a large-span hyperbolic metal roof truss. During operation, a first display 105 shows a three-dimensional model of the large-span hyperbolic metal roof truss constructed using BIM technology, along with the construction process. Simultaneously, a physical model is placed on a model frame 108 to simulate a real-world construction scenario. Workers scan the QR code in the QR code slot 109 to trigger an AR animation. The AR animation precisely matches the BIM data with the physical model, overlaying virtual construction steps, safety points, and other information onto the corresponding positions on the physical model. A second display 204, in conjunction with an acrylic plate tower 205, displays the roof truss structural details from multiple angles, achieving multi-view three-dimensional simulation. A heat dissipation mechanism cools the first display 105 through heat dissipation grooves 302 and slots 301. A stabilization mechanism uses a first magnet 401 and a second magnet 402 to fix the first mounting frame 102. A mobility mechanism uses an electric push rod 603 to control the casters 604 to move the device. Anti-slip pads 701 and anti-slip grooves 702 in the anti-slip placement mechanism ensure the device's stability.

[0032] This invention also discloses a construction simulation method for a safe construction device for a large-span hyperbolic metal roof truss, comprising the following steps: During operation, the first display 105 shows a 3D model of a large-span hyperbolic metal roof truss constructed using BIM technology, along with the construction process. Simultaneously, a physical model is placed on the model frame 108 to simulate a real-world construction scenario. Workers scan the QR code in the QR code slot 109 to trigger an AR animation. This AR animation precisely matches the BIM data with the physical model, overlaying virtual construction steps, safety precautions, and other information onto the corresponding positions on the physical model. The second display 204, in conjunction with the acrylic panel tower 205, displays the roof truss structural details from multiple angles, achieving multi-view 3D simulation. A heat dissipation mechanism uses heat dissipation slots 302 and openings 301 to cool the first display 105. A stabilization mechanism uses a first magnet 401 and a second magnet 402 to fix the first mounting frame 102. A mobility mechanism uses an electric push rod 603 to control the casters 604 to move the device. An anti-slip pad 701 and anti-slip groove 702 in the anti-slip placement mechanism ensure the device's stability. In the scene simulation mechanism, the first mounting frame 102 is slidably connected to the mounting slot 101, facilitating the disassembly and assembly of the first display 105. The first display 105 shows the 3D model of the metal roof truss constructed using BIM technology, construction schedule planning, material information, and other content. The model frame 108 holds a scaled-down physical roof truss model. The QR code in the QR code slot 109 is associated with AR animation. When staff scan the QR code, AR technology, based on BIM data, accurately overlays virtual construction processes and safety precautions, such as high-altitude operation protection and welding operation specifications, onto the physical model, achieving a deep integration of virtual information and the real construction scene. The transparent glass plate 106 is located above the first display 105, allowing construction personnel to observe the content on the screen below through it, while simultaneously combining it with the physical model above to form an intuitive display combining virtual and real elements. In the three-dimensional simulation mechanism, the second display 204 is installed in the second mounting frame 202 through the slot 203. Together with the acrylic plate tower 205, it displays the structural details and connection methods of the roof truss from different angles, making up for the shortcomings of the traditional planar perspective, providing a three-dimensional immersive viewing experience, and solving the problems of information fusion and perspective experience in the background technology. The heat dissipation mechanism has heat dissipation slots 302 on the lower surface of the first mounting frame 102 and slots 301 on the lower surface of the mounting frame 1, and the two are connected to each other. The first display 105 generates heat during operation, and the heat can be dissipated to the outside of the device in a timely manner through the heat dissipation slots 302 and slots 301, effectively preventing the performance of the first display 105 from deteriorating due to overheating, and ensuring the stability and smoothness of the BIM+AR simulation display; In the stabilizing mechanism, when the first mounting frame 102 slides into the mounting groove 101, the second magnet 402 on one side of the first mounting frame 102 attracts and adheres tightly to the first magnet 401 on the inside of the mounting groove 101, thereby firmly fixing the first mounting frame 102 in the mounting groove 101, preventing the first display 105 from shaking or shifting during device movement and use, ensuring that the BIM+AR simulation image is always stably presented, and the first handle 403 makes it easy for construction personnel to push and pull the first mounting frame 102, making operation convenient; The second handle 501, located in the middle of one side of the connecting frame 201, is for construction workers to grip and assist in moving or adjusting the device. An electric push rod 603 is installed in a hidden groove 602 inside the base 601 of the mobile mechanism. When the electric push rod 603 extends or retracts, it drives the casters 604 to extend or retract from the base 601. When the device needs to be moved, the electric push rod 603 extends, the casters 604 contact the ground, and the device can move flexibly; after reaching the designated position, the electric push rod 603 retracts, and the casters 604 are hidden. The anti-slip pad 701 on the underside of the base 601 contacts the ground. The anti-slip pad 701 is made of rubber, and the anti-slip groove 702 on its lower surface increases the friction with the ground, preventing the device from sliding and ensuring that the device is placed stably to meet the needs of different construction sites.
