Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for steel structure installation, specifically an auxiliary equipment and construction method for high-altitude installation of large-span steel structures. Background Technology

[0002] Large-span steel structures are building structures that use steel as the main load-bearing material to span extremely wide spaces. When installing such structures, a wide variety of auxiliary equipment is required for construction. However, the surface of the steel structure does not have a platform for construction workers to work on. During the construction process, tower cranes or hoists are needed to lift the construction workers into a suspended platform, which is extremely inconvenient. Summary of the Invention

[0003] This invention provides an auxiliary device and construction method for high-altitude installation of large-span steel structures, which overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this invention to solve its technical problem is: A high-altitude installation auxiliary equipment for large-span steel structures includes connecting fasteners and a work platform installed on the steel structure body. The work platform is installed on the steel structure body through connecting fasteners. The connecting fasteners include scaffolding and connectors. There is a gap between two adjacent steel structure bodies. The connectors are located close to the gap, and each pair of adjacent steel structure bodies is fixed together by the connectors. The scaffolding is fixed to the surface of the connectors. The connector includes a filling plate, an I-shaped plate, an edge fixing plate, and a connecting plate. The filling plate and the I-shaped plate are disposed in the gap between two adjacent steel structure bodies, and the I-shaped plate is symmetrically disposed on the upper and lower sides of the filling plate. The edge fixing plate and the connecting plate are symmetrically disposed on the front and rear sides of the filling plate. The edge fixing plate abuts against the edge of the steel structure body, and the connecting plate tube passes through the adjacent edge fixing plate and is inserted into the steel structure body. The scaffolding is respectively installed on the upper part and the left and right sides of the connecting fasteners, and the scaffolding abuts against the surface of the edge fixing plate and the steel structure body respectively; The filling insert includes a U-shaped plate and sub-plates symmetrically arranged on the front and rear sides of the U-shaped plate. The front and rear ends of the U-shaped plate abut against the edges of the steel structure body on the left and right sides, respectively. The U-shaped plate has a protrusion in the middle that protrudes towards the steel structure body on both sides. The protrusion extends into the steel structure body and abuts against the steel structure body. The I-beam includes steel clamps and square steel blocks. The steel clamps are symmetrically arranged on the upper and lower sides of the square steel blocks. The width of the steel clamps is greater than the gap between two adjacent steel structure bodies, and both steel clamps abut against the inner and outer ends of the steel structure body. The filling insert is provided with a first insert rod, which passes through the steel clamps and the filling insert from top to bottom.

[0005] A preferred technical solution is that the scaffolding includes a support first and a support second. The support second has an M-shaped structure, and the lower part of the support second is connected to the plug-in plates provided on the surfaces of two edge fixing plates, while the upper end of the support second is fixed to the workbench. The bracket is symmetrically arranged on the left and right sides of the steel structure body. The bracket extends along the length of the edge fixing plate. The bracket has a threaded part on the side near the edge fixing plate. When the bracket is installed on the steel structure body, the threaded part passes through the threaded tube on the side of the edge fixing plate and abuts against the surface of the steel structure body, and the threaded part and the threaded tube form a threaded connection.

[0006] A preferred technical solution is that cable positioning grooves are provided on the two opposite sides of the two steel clamps. When the steel clamps are lifted by cables, the cables are positioned by the cable positioning grooves.

[0007] A preferred technical solution is that the connecting plate is provided with a slot and a second insert rod. The second insert rod is positioned towards the steel structure body. The steel structure body and the second insert rod are respectively provided at corresponding positions. The second insert rod is inserted into the steel structure body. The edge fixing plate is inserted into the slot through the plug plate provided at its lower end, and the edge fixing plate abuts against the steel structure body and the connecting plate. The steel clamp plate near the middle of the steel structure body in the I-beam has a limiting groove on its surface that corresponds to the second insertion rod. When the connecting plate is fixed on the steel structure body, the second insertion rod penetrates the steel structure body and is inserted into the limiting groove.

[0008] In a preferred embodiment, the width of the square steel block is equal to the gap between two adjacent steel structure bodies. When the I-beam is installed into the gap, both steel structure bodies abut against the surface of the square steel block, and the length direction of the steel clamp is parallel to the length direction of the steel structure body.

[0009] A method for high-altitude installation of large-span steel structures, based on the aforementioned auxiliary equipment for high-altitude installation of large-span steel structures, wherein when installing the steel structure body, two suspended steel structure bodies can be fixed by connecting fasteners, and a work platform is installed on the side and top of the connecting fasteners to form a working platform on the side and top of the connecting fasteners. When fixing two adjacent steel structure bodies with connecting fasteners, the two steel structure bodies must first be brought close together and made parallel to each other. Then, multiple I-beams are installed on the side of one of the steel structure bodies. The edge of the steel structure body is inserted between two square steel blocks in the corresponding I-beam, and the I-beam is made parallel to the steel structure body. Then, the other steel structure body is pushed into the other end of the I-beam, so that the two steel structure bodies are supported by the I-beam. A filler plate is inserted between the two steel structure bodies, and then the I-beam and the filler plate are fixed by the second insert rod.

[0010] Compared with existing technologies, this technical solution has the following advantages: In this invention, the connecting fastener consists of a connector and scaffolding. Its core function is to provide a stable and reliable high-altitude work platform for construction workers while achieving structural connection between adjacent steel structures. In existing technologies, there is a gap between two adjacent steel structures, which requires rigid fixation through connectors to ensure overall structural stability. This solution fully utilizes this necessary connection location, integrating scaffolding on the basis of the original connection function. Specifically, the filling plate and I-beam are placed in the gap between the two steel structures, the edge fixing plate abuts against the edge of the steel structure, and the connecting plate passes through the edge fixing plate and inserts into the interior of the steel structure for firm anchoring. The scaffolding is directly fixed to the surface of the connector and is arranged on the upper part and left and right sides of the connecting fastener, with its supporting ends abutting against the edge fixing plate and the surface of the steel structure, respectively. Thus, the scaffolding does not require additional support structures and can form a stable working platform based on the existing connector, allowing construction workers to work safely without relying on a suspended platform, significantly improving construction efficiency and safety.

Detailed Implementation

[0020] like Figures 1 to 7 As shown, the present invention proposes an auxiliary device for high-altitude installation of large-span steel structures, including a connecting fastener 1 and a work platform 2 installed on the steel structure body 100. The work platform 2 is installed on the steel structure body 100 through the connecting fastener 1. The connecting fastener 1 includes scaffolding and connectors. There is a gap between two adjacent steel structure bodies 100. The connectors are set close to the gap, and each pair of adjacent steel structure bodies 100 are fixed together by the connectors. The scaffolding is fixed to the surface of the connectors. The connector includes a filling plate 11, an I-shaped plate 12, an edge fixing plate 13, and a connecting plate 14. The filling plate 11 and the I-shaped plate 12 are disposed in the gap between two adjacent steel structure bodies 100, and the I-shaped plate 12 is symmetrically disposed on the upper and lower sides of the filling plate 11. The edge fixing plate 13 and the connecting plate 14 are symmetrically disposed on the front and rear sides of the filling plate 11. The edge fixing plate 13 abuts against the edge of the steel structure body 100, and the connecting plate 14 passes through the adjacent edge fixing plate 13 and is inserted into the steel structure body 100. The scaffolding is respectively installed on the upper part and the left and right sides of the connecting fastener 1, and the scaffolding abuts against the surface of the edge fixing plate 13 and the steel structure body 100 respectively; The filling insert 11 includes a U-shaped plate and sub-plates symmetrically arranged on the front and rear sides of the U-shaped plate. The front and rear ends of the U-shaped plate abut against the edges of the steel structure body 100 on the left and right sides, respectively. The U-shaped plate has a protrusion in the middle that protrudes towards the steel structure body 100 on both sides. The protrusion extends into the steel structure body 100 and abuts against the steel structure body 100. The I-beam plate 12 includes a steel clamp plate 121 and a square steel block 122. The steel clamp plate 121 is symmetrically arranged on the upper and lower sides of the square steel block 122. The width of the steel clamp plate 121 is greater than the gap between two adjacent steel structure bodies 100, and both steel clamp plates 121 abut against the inner and outer ends of the steel structure body 100. The filling insert plate 11 is provided with a first insert rod 111, which passes through the steel clamp plate 121 and the filling insert plate 11 from top to bottom.

[0021] In this invention, the connecting fastener 1 consists of a connector and scaffolding. Its core function is to provide a stable and reliable high-altitude work platform for construction workers while achieving structural connection between adjacent steel structure bodies 100. In the prior art, there is a gap between two adjacent steel structure bodies 100, which needs to be rigidly fixed by connectors to ensure the overall structural stability. This solution makes full use of this necessary connection position and integrates scaffolding on the basis of the original connection function.

[0022] Specifically, the filling plate 11 and the I-beam plate 12 are placed in the gap between the two steel structure bodies 100. The edge fixing plate 13 abuts against the edge of the steel structure body 100. The connecting plate 14 passes through the edge fixing plate 13 and is inserted into the interior of the steel structure body 100 to achieve a firm anchorage. The scaffolding is directly fixed to the surface of the connector and is arranged on the upper part and left and right sides of the connecting fastener 1, with its supporting ends abutting against the edge fixing plate 13 and the surface of the steel structure body 100, respectively. Thus, the scaffolding does not require an additional support structure and can form a stable working platform based on the existing connector, allowing construction workers to work safely without relying on a suspended platform, significantly improving construction efficiency and safety.

[0023] The function of the insert rod 111 is to vertically penetrate and lock the filler plate 11 and the I-shaped plate 12, ensuring that they maintain their relative positions under stress. The filler plate 11 is mainly used to fill the gap between two adjacent steel structure bodies 100, and provides basic support by abutting against the edge and internal protrusion of the steel structure body 100 through its U-shaped plate structure; the I-shaped plate 12 is composed of steel clamping plates 121 and square steel blocks 122. The width of the steel clamping plates 121 is greater than the gap, and they symmetrically clamp the inner and outer end faces of the steel structure body 100 from top to bottom, playing a lateral clamping role.

[0024] However, relying solely on the stacked fit of the filling plate 11 and the I-beam 12 is prone to relative slippage when bearing scaffolding and construction loads. The insert rod 111 passes through the steel clamp 121 and the filling plate 11 sequentially from top to bottom, mechanically locking them vertically to prevent the I-beam 12 from detaching from the filling plate 11 or becoming misaligned. Therefore, although the insert rod 111 does not directly bear external loads, it ensures the integrity and stability of the overall structure of the connecting fastener 1 by restraining the relative movement of the filling plate 11 and the I-beam 12, making it a key limiting component for ensuring the safety of the aerial work platform.

[0025] Furthermore, the scaffolding includes a first support 15 and a second support 16. The second support 16 has an M-shaped structure, and the lower part of the second support 16 is connected to the plug-in plates 131 provided on the surfaces of the two edge fixing plates 13, while the upper end of the second support 16 is fixed to the workbench 2. The first support 15 is symmetrically arranged on the left and right sides of the steel structure body 100. The first support 15 extends along the length direction of the edge fixing plate 13. The side of the first support 15 near the edge fixing plate 13 is provided with a threaded part 151. When the first support 15 is installed on the steel structure body 100, the threaded part 151 passes through the threaded tube 132 provided on the side of the edge fixing plate 13 and abuts against the surface of the steel structure body 100, and the threaded part 151 and the threaded tube 132 form a threaded connection. Specifically, bracket 15 is symmetrically arranged on the left and right sides of the steel structure body 100 and extends along the length of the edge fixing plate 13. A threaded portion 151 is provided on the side closest to the edge fixing plate 13. This threaded portion 151 passes through a pre-set threaded tube 132 on the side of the edge fixing plate 13 and directly abuts against the surface of the steel structure body 100, forming a reliable threaded connection with the threaded tube 132. This structure allows bracket 15 to apply a continuous clamping force to the edge fixing plate 13, firmly pressing the edge fixing plate 13 against the side wall of the steel structure body 100.

[0026] Since the connecting plate 14 needs to pass through the edge fixing plate 13 and be inserted into the steel structure body 100 for anchoring, the positional stability of the edge fixing plate 13 directly affects the fixing effect of the connecting plate 14. The bracket 15 securely locks the edge fixing plate 13 to the steel structure body 100 via a threaded connection, effectively preventing loosening, displacement, or warping during stress, thus ensuring that the connecting plate 14 remains in its designed position and maintains its anchoring function. Therefore, the bracket 15 not only provides support as a component of the scaffolding but also strengthens the connection rigidity and integrity between the edge fixing plate 13, the connecting plate 14, and the steel structure body 100 through a mechanical clamping mechanism.

[0027] Furthermore, cable positioning grooves 1211 are provided on the outer surfaces of the two steel clamps 121 that are far apart. When the steel clamps 121 are lifted by cables, the cables are positioned by the cable positioning grooves 1211. Since the cable positioning grooves 1211 are located on the outer surfaces of the two steel clamps 121 that are far apart, their main function is to provide positioning and guidance for the cables when installing the I-beam 12, so as to facilitate the stable lifting of the entire I-beam 12 by tower cranes or hoisting equipment. In the actual installation process, the hoisting cables can be embedded in the cable positioning grooves 1211 to prevent the cables from slipping or deviating during the lifting process, thereby ensuring that the attitude of the I-beam 12 is controllable and the force is evenly distributed in the air.

[0028] Furthermore, since the I-beam 12 needs to be embedded in the narrow gap between two adjacent steel structure bodies 100, and the width of its steel clamp 121 is larger than this gap, direct vertical insertion would cause interference. Therefore, during the hoisting process, the I-beam 12 can be rotated and adjusted using a cable and cable positioning groove 1211: first, the I-beam 12 is hoisted to the vicinity of the installation position in an inclined or vertical posture, then rotated moderately around its axis so that its steel clamp 121 enters the gap with a smaller cross-section, and then rotated back to the center so that the steel clamp 121 is finally horizontally clamped between the inner and outer end faces of the two steel structure bodies 100. This rotational embedding method relies on the stable positioning of the cable in the cable positioning groove 1211, avoiding component swaying or loss of control during hoisting, and improving installation accuracy and operational safety.

[0029] Furthermore, the connecting plate 14 is provided with a slot 141 and a second insert 142. The second insert 142 is positioned towards the steel structure body 100. The steel structure body 100 is provided with a socket 101 at the corresponding position of the second insert 142. The second insert 142 is inserted into the steel structure body 100 through the socket 101. The edge fixing plate 13 is inserted into the slot 141 through the plug plate 131 provided at its lower end. The edge fixing plate 13 abuts against the steel structure body 100 and the connecting plate 14. The steel clamp plate 121 in the I-shaped plate 12 near the middle of the steel structure body 100 is provided with a limiting groove 1212 corresponding to the second insert 142. When the connecting plate 14 is fixed on the steel structure body 100, the second insert 142 penetrates the steel structure body 100 and is inserted into the limiting groove 1212. The structural design of the connecting plate 14, through the slot 141, the second insert 142 and the socket 101 on the steel structure body 100, achieves a modular, precise positioning and easy installation connection method, and effectively enhances its overall fixation with the edge fixing plate 13 and the steel structure bodies 100 on the left and right sides.

[0030] First, during installation, the connecting insert 14 aligns its insert rod 142 with the pre-set insertion port 101 on the steel structure body 100 and is directly inserted to complete the initial positioning and anchoring with the steel structure body 100. This insert-type connection eliminates the need for on-site welding or complex tightening operations, significantly simplifying the high-altitude operation process and improving installation efficiency. Simultaneously, after penetrating the steel structure body 100, the insert rod 142 further inserts into the limiting groove 1212 on the surface of the steel clamp 121 near the center of the I-beam 12, forming a double axial and radial limit on the connecting insert 14, preventing it from loosening or detaching under stress, thereby improving the overall structural stability.

[0031] Secondly, the edge fixing plate 13 is inserted into the slot 141 on the connecting plate 14 via the plug-in plate 131 at its lower end, achieving a quick-fit connection between the two. This plug-in structure not only facilitates on-site assembly but also creates rigid constraints between the edge fixing plate 13 and the connecting plate 14 in both vertical and horizontal directions. Simultaneously, the outer side of the edge fixing plate 13 abuts against the edge of the steel structure body 100, while its inner side is tightly connected to the connecting plate 14 via the plug-in plate 131. The connecting plate 14 itself penetrates and is anchored within the steel structure body 100, and together the three form a closed force-bearing system.

[0032] Furthermore, the width of the square steel block 122 is equal to the gap between two adjacent steel structure bodies 100. When the I-beam plate 12 is installed into the gap, both steel structure bodies 100 abut against the surface of the square steel block 122, and the length direction of the steel clamp plate 121 is parallel to the length direction of the steel structure body 100.

[0033] Based on the above, this invention also proposes a method for high-altitude installation of large-span steel structures. Based on the aforementioned auxiliary equipment for high-altitude installation of large-span steel structures, when installing the steel structure body 100, the two suspended steel structure bodies 100 can be fixed by the connecting fastener 1, and the work platform 2 is installed on the side and top of the connecting fastener 1 to form a working platform on the side and top of the connecting fastener 1. When fixing two adjacent steel structure bodies 100 with the connecting fastener 1, the two steel structure bodies 100 should first be brought close together and made parallel to each other. Then, multiple I-beam plates 12 are installed on the side of one of the steel structure bodies 100. The edge of the steel structure body 100 is inserted between two square steel blocks 122 in the corresponding I-beam plate 12. After the I-beam plate 12 is made parallel to the steel structure body 100, the other steel structure body 100 is pushed into the other end of the I-beam plate 12 so that the two steel structure bodies 100 are supported by the I-beam plate 12. The filling insert 11 is then inserted between the two steel structure bodies 100. Finally, the I-beam plate 12 and the filling insert 11 are fixed by the insert rod 111.

[0034] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
