Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and specifically relates to a portable installation support construction platform. Background Technology

[0002] In recent years, with the rapid development of steel box girder cable-stayed bridge construction in my country, higher demands have been placed on the efficiency of temporary scaffolding erection. The traditional method of stacking scattered components on-site and then assembling them into temporary scaffolding is cumbersome and inefficient, failing to meet the demands of rapid progress in modern engineering. Furthermore, on-site assembly brings challenges such as difficulty in quality control, large storage space requirements, and increased construction complexity and uncertainty. Traditional temporary scaffolding erection methods, due to their inherent limitations—such as requiring extensive manual labor, dependence on site conditions, and a lack of standardized manufacturing processes—are gradually becoming inadequate for the speed and quality standards of current bridge construction projects. Especially in large-scale bridge projects, the erection time of temporary scaffolding directly impacts the overall project schedule; therefore, improving the efficiency of temporary scaffolding erection has become an urgent problem to be solved.

[0003] Existing methods for erecting temporary scaffolding typically involve the following steps: First, transporting various loose steel pipe piles and other structural components to the designated location on the construction site; second, driving the steel pipe piles according to the design drawings; then, using hoisting equipment to lift and install each structural component onto the steel pipe piles; finally, completing the welding connections between the parts to form a complete temporary scaffold. However, this method is not only time-consuming but also easily affected by factors such as weather changes and differences in personnel skill levels, making it difficult to guarantee construction quality and progress. Furthermore, the space constraints on the construction site make the stacking and management of loose components more difficult, increasing safety risks. Utility Model Content

Detailed Implementation

[0024] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 5 This utility model provides a portable installation support platform, comprising: a platform semi-finished product 100, a steel pipe column 200, and a limiter. (See reference...) Figure 1 and Figure 3The platform semi-finished product 100 includes a foundation horizontal bracing 110, two platform panels 120, and railings 130. The foundation horizontal bracing 110 and railings 130 are fixedly connected. The two platform panels 120 are spliced ​​in half and fixed to the end faces of the foundation horizontal bracing 110 and railings 130. Lifting holes 122 are provided on the platform panels 120. A steel pipe column 200 is provided with platform support components, which are welded to the steel pipe column 200. A limiter is located on the edge of the steel pipe column 200, providing vertical linear and rotational constraints for the inclined support. This utility model significantly improves the installation efficiency and quality of temporary supports by proposing a combination of a portable construction platform and temporary support pipe piles. First, the structural design of the platform semi-finished product 100 integrates the foundation horizontal bracing 110, platform panels 120, and railings 130 into a single module, reducing on-site assembly work and lowering construction complexity. This modular design not only improves installation speed but also ensures the connection strength and stability between components, avoiding quality fluctuations caused by on-site welding and assembly in traditional methods. Secondly, refer to... Figure 4 The design of the lifting holes 122 on the platform panel 120 allows the platform to be quickly lifted and installed by a crane, further shortening the construction cycle. The position of the lifting holes 122 is precisely calculated to ensure balance and safety during the lifting process, avoiding structural deformation or damage caused by improper lifting. Furthermore, the platform support components on the steel pipe columns 200 are welded to the columns, providing a robust support point and ensuring the stability and safety of the platform during high-altitude operations. Finally, the limiter design provides vertical linear and rotational constraints for the inclined supports, effectively preventing potential offset and rotation problems during construction and ensuring the overall rigidity and stability of the support structure. By optimizing the platform structure and connection methods, construction efficiency and quality are significantly improved, safety risks are reduced, and the development of bridge engineering construction is promoted.

[0025] Furthermore, referring to Figure 1The railing 130 includes a front railing 131 and two side railings 132, with the two side railings 132 vertically connected to both sides of the front railing 131. The combined design of the front railing 131 and the side railings 132 provides comprehensive safety protection for construction workers. The vertical connection of the front railing 131 and the side railings 132 forms a closed protective space, effectively preventing falls by construction workers while working at height. This design not only improves construction safety but also enhances the psychological safety of construction workers, enabling them to operate in a more stable environment. Of course, this invention does not limit the specific height of the railing 130. Preferably, the height of the railing 130 is set to approximately 1.2 meters. The structural design of the railing 130 takes into account ergonomic principles, ensuring that it does not affect the operational flexibility of construction workers while providing sufficient protection. Of course, this invention does not limit the specific material of the railing 130. Preferably, the railing 130 is made of high-strength steel, which has good impact resistance and corrosion resistance, ensuring reliability and durability in long-term use. Furthermore, this utility model does not limit the fixing method of the front railing 131 and the side railing 132. Preferably, the front railing 131 and the side railing 132 are fixed by welding. Further, referring to... Figure 4 The platform panel 120 has a semi-circular hole 121. Two platform panels 120 are spliced ​​in half and welded to the bottom end face of the foundation tie 110 and the railing 130. The steel pipe column 200 can pass through the circular hole formed in the center of the two platform panels 120. Moreover, the size of the platform panel 120 and the position of the semi-circular hole 121 can be adjusted according to the pile diameter and pile spacing of the steel pipe column 200. The design of the semi-circular hole 121 allows the platform panel 120 to perfectly match steel pipe columns 200 of different diameters, ensuring accurate positioning of the platform during installation. By adjusting the position of the semi-circular hole 121, the platform can adapt to the requirements of different pile diameters and pile spacings, making it suitable for various bridge engineering construction scenarios. This flexibility not only improves the versatility of the platform but also reduces the cost and time of customized production, enabling the platform to be used in more projects. At the same time, the design of the semi-circular hole 121 simplifies the installation process. Construction workers only need to align the platform panel 120 with the opening of the steel pipe column 200 to quickly complete the installation, greatly improving work efficiency.

[0026] Furthermore, after assembling the platform semi-finished product 100, a crane is used to lift the platform with the help of the lifting holes 122. Of course, this utility model does not limit the specific type of the lifting holes 122; preferably, the lifting holes 122 are beak-shaped holes. Furthermore, this utility model does not limit the specific position of the platform support components. Preferably, the position of the platform support components is 1.5 meters to 1.8 meters below the top of the steel pipe column 200 to ensure the stability and safety of the platform during high-altitude operations. The position of the platform support components is determined based on the circumferential weld of the steel pipe column 200, the weld points of the diagonal supports, and the average height of the workers. For example, the platform support components can be set at a position 1.5 meters below the top of the steel pipe column 200 and at each diagonal support position. Furthermore, the portable platform of this utility model system also includes two total station monitoring devices 300. The total station monitoring devices 300 are used to monitor the verticality and flatness of the steel pipe column 200 in real time during the splicing process. The total station monitoring device 300 can monitor the verticality and flatness of the steel pipe columns 200 in real time during the splicing process, ensuring that the installation of each layer of columns meets the design requirements. (Refer to...) Figure 5 Two total station monitoring devices 300 are located at two 90° vertical angles on the steel pipe column 200. By setting up a total station at each of the two 90° vertical angles, locking the horizontal angle, and measuring the horizontal distance between the top and bottom of the column, the verticality and flatness of the column can be precisely controlled, avoiding structural deviations caused by installation errors. This real-time monitoring method not only improves installation accuracy but also reduces the time and cost of subsequent adjustments, ensuring the stability and safety of the entire support system.

[0027] Furthermore, the platform support components are fixed to the platform semi-finished product 100 at the contact points using spot welding. Spot welding is an efficient and reliable connection method that can quickly fix the platform support components to the platform semi-finished product 100, significantly shortening the installation time. Compared to traditional bolted or full-welded connections, spot welding eliminates the need for additional fasteners, reducing material costs and installation steps, making platform installation more convenient. Secondly, spot welding provides sufficient connection strength to ensure the stability and safety of the platform during high-altitude operations. Although the welding area of ​​spot welding is small, the greater penetration depth effectively transfers the load, ensuring a firm connection between the platform support components and the platform semi-finished product 100. In addition, spot welding offers excellent durability, maintaining a stable connection during prolonged use and preventing loosening or detachment.

[0028] Furthermore, the limiter is cut from a steel plate. Cutting the steel plate ensures the dimensional accuracy and surface quality of the limiter, allowing it to perfectly fit the steel pipe column 200 during installation and provide reliable constraint. The dimensional accuracy of the limiter directly affects its constraint effect on the inclined support. Only a precisely sized limiter can effectively prevent the inclined support from shifting and rotating during construction, ensuring the overall rigidity and stability of the support system. Of course, this invention does not limit the specific dimensions of the limiter; preferably, the basic dimensions of the limiter are thickness × width × length = 20mm × 50mm × 50mm. This aims to ensure that the limiter provides the best constraint effect during construction. The limiter provides linear and rotational constraints in the vertical direction for the inclined support, allowing welding construction of the inclined support without unhooking. Throughout the entire process, the inclined support will not directly contact the construction platform, providing only a safe high-altitude working space for construction personnel. The 50mm x 50mm width and length design allows the limiter to fit perfectly against the edge of the 200mm steel pipe column, providing reliable restraint. This size selection not only considers the functional requirements of the limiter but also takes into account the convenience of construction. An excessively large limiter would hinder the operator's work, while an excessively small one would not provide sufficient restraint. The 20mm thickness ensures that the limiter has sufficient strength and rigidity to withstand large loads and impacts, preventing deformation or damage during construction.

[0029] Furthermore, the steel pipe column 200 is assembled into a first layer of pipe piles 210, a second layer of pipe piles 220, and a third layer of pipe piles 230. All three layers are welded together in alignment. This design, where each layer of pipe piles is welded to its correct position, significantly improves the overall stability and safety of the support system. The advantage of layered assembly is that construction workers can immediately begin assembling the next layer after completing the installation of one layer of pipe piles, greatly improving construction efficiency. Moreover, the layered steel pipe column 200 proposed in this application connects the short sides of the column, reducing the need for workers to climb up and down and avoiding the risk of falls from heights.
