Description

Technical Field

[0001] This utility model relates to a high-altitude work platform for the construction of large-span steel structure roofs, belonging to the field of building construction. Background Technology

[0002] Structures such as trusses and frames are commonly seen on the eaves or roofs of buildings, used to support and install the roof. Currently, many buildings, in pursuit of a grand, imposing, and aesthetically pleasing visual effect, often feature wide eaves or roofs. This necessitates the use of large-span structures to provide stable support and installation, ensuring the safety of the roof and the durability of the building.

[0003] Because of their large span and excessive weight, this type of structure often faces difficulties in being hoisted as a whole using a tower crane. Therefore, during construction, such large-span structures are often broken down into multiple hoisting units and hoisted in batches to reduce the weight of each hoisting operation. During the hoisting process, each hoisting unit is lifted onto a high-altitude work platform pre-built on the main building structure before being assembled between the units.

[0004] Currently, there is a technology that involves building a full-span scaffold or steel lattice column support structure on the ground and laying a working platform on top of it to form an aerial work platform. However, this type of aerial work platform occupies a large space and affects the normal progress of other construction work on the ground.

[0005] Another technique involves hoisting large-span structures like I-beams onto the main building and then laying a work platform on top to create an aerial work platform. While this type of platform does not interfere with other construction work on the ground and offers good structural stability, the large weight of some of its components (referring to large-span structures) necessitates the use of large hoisting equipment, thus increasing hoisting costs. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an aerial work platform for the construction of large-span steel structure roofs, which has comprehensive advantages such as being located above the ground and not significantly affecting other construction operations, facilitating hoisting by small tower cranes, and having a stable structure.

[0007] A high-altitude work platform for the construction of a large-span steel roof includes a truss body. The truss body includes at least two planar truss units for hoisting onto truss support beams located on the main structure of the building and suspended above the ground, and a plurality of truss connecting beams located between two adjacent planar truss units and connected in the air to the corresponding two planar truss units. The upper surface of the truss body is provided with a work platform plate connected in the air.

[0008] Preferably, the lower chord of the planar truss unit is provided with a lower mounting plate located between two planar truss units, and the lower mounting plate has a horizontal plane that supports and mounts the corresponding truss connecting beam.

[0009] Preferably, the horizontal plane is coplanar with the upper surface of the corresponding lower chord, and the two together form a standing surface for a human body to stand on.

[0010] Preferably, the upper chord of the planar truss unit is provided with an upper mounting plate located between two planar truss units, and the upper mounting plate has a horizontal plane two that supports and mounts the corresponding truss connecting beam.

[0011] Preferably, the distance between two planar truss units is 700mm to 1000mm.

[0012] Preferably, the lower chord of the planar truss unit is provided with a lower connecting plate for mounting on the truss support beam, and the lower connecting plate is provided with a fastening connector for connecting to the truss support beam.

[0013] Preferably, the upper chord of the planar truss unit is provided with an upper connecting plate for connecting to an upper chord embedded part provided on the main body of the building.

[0014] Preferably, the work platform is provided with several guardrail interfaces.

[0015] Preferably, the working platform plate and the truss body are detachably connected, the truss connecting beam and the planar truss unit are detachably connected, and the planar truss unit and the truss support beam are detachably connected.

[0016] In summary, this utility model has the following beneficial effects: 1. This utility model uses a truss structure to replace the existing full-span scaffolding or lattice support columns, I-beams, and other support structures to support or support the work platform. Furthermore, the planar truss units in the truss structure are connected to the truss support beams on the main building and suspended above the ground. At the same time, the truss connecting beams in the truss structure are connected in the air to the corresponding two planar truss units. The work platform is also connected in the air to the upper surface of the truss structure. This type of high-altitude work platform has many comprehensive advantages, such as being above the ground and not affecting other construction operations, facilitating hoisting by small tower cranes, and structural stability.

[0017] 2: In this utility model, the lower mounting plate on the lower chord has a horizontal plane that supports and mounts the corresponding truss connecting beam, so that the corresponding truss connecting beam can be supported when installing the truss connecting beam without manual support, thus facilitating installation.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example: A high-altitude work platform for the construction of a large-span steel structure roof, see [link / reference]. Figure 1 The diagram shown is a simplified installation schematic of the aerial work platform. Figure 2 The isometric view of the aerial work platform shown includes a truss body 1, which includes at least two planar truss units 11. The planar truss units 11 are hoisted onto truss support beams 0 that are located on the main building and suspended above the ground. Multiple truss connecting beams 12 are provided between two adjacent planar truss units 11, and these truss connecting beams 12 are connected in the air to the corresponding two planar truss units 11. The upper surface of the truss body 1 is provided with a work platform plate 2 for workers to assemble the various hoisting unit groups (i.e., those mentioned in the background art) used for supporting and installing the roof, and the work platform plate 2 is connected in the air to the truss body 1.

[0021] This type of aerial work platform uses a truss body 1 to replace the existing full-span scaffolding, lattice support columns, or I-beams for supporting or supporting the platform slab. Firstly, since the truss body 1 is connected to the truss support beams 0 suspended above the ground on the main building structure, there are essentially no components or structures on the ground below the aerial work platform to support it. Therefore, it does not significantly interfere with other construction work on the ground below the platform. Secondly, the truss body 1, which supports or supports the platform slab, has a planar... Truss unit 11 is configured to be connected to truss support beam 0 via hoisting. Its truss body 1 is configured to be connected to the planar truss unit 11 via a special connection method called "aerial connection". The work platform plate 2 is also configured to be connected via a special connection method called "aerial connection". That is, the aerial work platform is assembled at high altitude, avoiding the overall hoisting of the aerial work platform, thereby saving the cost of large hoisting equipment and enabling hoisting with small hoisting equipment. At the same time, the aerial work platform uses the truss body 1 as the support structure, ensuring the basic requirement of structural stability.

[0022] Structurally, the planar truss unit 11 includes recognized basic structures such as upper chord 111, lower chord 112, and web members 113. The upper chord 111 and lower chord 112 are connected by multiple web members 113. The upper chords 111 of two planar truss units 11 are connected by multiple truss connecting beams 12, and similarly, the lower chords 112 of two planar truss units 11 are also connected by multiple truss connecting beams 12. Of course, the planar truss unit 11 itself can be composed of multiple splicing units, each splicing unit having the aforementioned upper chord 111, lower chord 112, and web members 113. The planar truss unit 11 can be assembled on the ground by selecting an appropriate number of splicing units according to the actual width of the eaves or roof.

[0023] In this embodiment, see Figure 3 As shown, a lower mounting plate 115 is provided on the lower chord 112 between two planar truss units 11. Multiple lower mounting plates 115 are arranged along the length of the lower chord 112. Each lower mounting plate 115 has a horizontal plane for supporting and mounting the corresponding truss connecting beam 12. This horizontal plane arrangement allows the corresponding truss connecting beam 12 to be supported during installation without manual support, thus facilitating installation. A more superior design is shown below. Figure 4As shown, the horizontal plane is coplanar with the upper surface of the corresponding lower chord 112, so that the two form a standing surface for the human body to stand on with a larger standing area. Otherwise, the feet can only stand on the upper surface of the lower chord 112 or on the horizontal plane to assemble the truss connecting beam 12 on the upper chord 111. Of course, it should be noted that the so-called standing does not necessarily mean that the human body stands upright. It can be a bent or tilted posture.

[0024] In this embodiment, see Figure 5 As shown, the upper chord 111 is provided with an upper mounting plate 114 located between two planar truss units 11. The upper mounting plate 114 has a second horizontal plane that supports and installs the corresponding truss connecting beam 12. Similar to the first horizontal plane, the second horizontal plane allows the corresponding truss connecting beam 12 to be supported when it is installed, without the need for manual support, thus facilitating installation.

[0025] See Figure 1 , Figure 6 As shown, the lower chord 112 of the planar truss unit 11 is provided with a lower connecting plate 116 for mounting on the truss support beam 0. The lower connecting plate 116 is provided with a fastening connector that is connected to the truss support beam 0. The fastening connector is not shown in the figure. The fastening connector can be a threaded fastener such as a bolt.

[0026] See Figure 1 , Figure 6 As shown, the main body of the building is also pre-embedded with an upper chord embedded part 01 corresponding to the upper chord 111. The structure of the upper chord embedded part 01 is not limited. The upper chord 111 of the planar truss unit 11 is provided with an upper connecting plate 117 for connecting with the upper chord embedded part 01 provided on the main body of the building. The two can be connected by threaded fasteners such as bolts.

[0027] The work platform 2 is equipped with several guardrail interfaces, which are not shown in the attached drawing. When guardrails are installed in the guardrail interfaces, the risk of workers falling from the work platform 2 is reduced.

[0028] This aerial work platform serves as a temporary support structure and needs to be dismantled after the roof construction is completed. Therefore, the platform plate 2 and truss body 1 are detachably connected, as are the truss connecting beam 12 and planar truss unit 11. Specifically, the lower mounting plate 115 and truss connecting beam 12 are detachably connected, as are the upper mounting plate 114 and truss connecting beam 12. The planar truss unit 11 and truss support beam 0 are detachably connected, specifically the lower connecting plate 116 and truss support beam 0. All detachable connections are achieved using threaded fasteners such as bolts. With these detachable connections, the dismantled platform plate 2, truss connecting beam 12, and planar truss unit 11 can be sequentially lifted to the ground using a small tower crane, without needing to lift the entire aerial work platform.

[0029] An installation method applicable to the above-mentioned aerial work platform includes: Two planar truss units 11 are assembled on the ground; Two planar truss units 11 are hoisted onto the truss support beam 0 on the main building and fixed at intervals of 700mm to 1000mm. In this embodiment, the interval is set to 750mm.

[0030] A plurality of truss connecting beams 12, which together with the two planar truss units 11 form a truss body 1, are installed between the two planar truss units 11; A working platform plate 2 is fixed on the upper surface of the truss 1.

[0031] In this method, by assembling a partial structure of the aerial work platform—the planar truss unit 11—on the ground, and then assembling it in the air with the truss connecting beam 12 and the work platform plate 2 to form the entire aerial work platform, a small tower crane can be selected, thereby saving the cost of large hoisting equipment.

[0032] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
