Description

Technical Field

[0001] This utility model relates to the field of building formwork reinforcement structure technology, specifically a spherical connection type aluminum formwork back rib staggered positioning structure. Background Technology

[0002] With the widespread application of prefabricated buildings, the use of aluminum formwork systems on construction sites is increasing. Their advantages include lightweight structure, high reusability, and short construction cycle, effectively improving the standardization and industrialization level of building projects. In aluminum formwork systems, the aluminum formwork back ribs, as crucial supporting components, have a critical impact on the overall flatness and structural safety of the formwork. However, in actual construction, due to component prefabrication errors, on-site assembly deviations, and inconsistent positioning of reserved holes, problems such as height misalignment or hole displacement often occur between adjacent aluminum formwork back ribs. This prevents the formwork from being properly connected and reinforced, and in severe cases, even affects the quality of concrete pouring.

[0003] The misalignment of back braces is particularly prevalent at corners, non-standard joints, and irregular nodes in building structures. Current technologies often employ temporary welding, steel pipe supports, or custom connectors, which are complex, have low reusability, and cannot meet the rapid response requirements of standardized construction. Furthermore, some reinforced structures experience strength degradation, amplified installation errors, and localized stress concentrations over long-term use, hindering project quality control and on-site construction safety. Therefore, there is an urgent need for a structurally sound, accurately positioned, easily installed, and reusable back brace misalignment connection and reinforcement device to solve the technical challenge of rapid and stable connection of back braces in existing aluminum formwork systems.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] like Figures 1-6 As shown in the figure, the spherical connection type aluminum mold back rib staggered positioning structure provided by this utility model includes a first hemispherical shell 1 and a second hemispherical shell 2, and the first hemispherical shell 1 and the second hemispherical shell 2 are detachably connected.

[0032] The surfaces of the first hemispherical shell 1 and the second hemispherical shell 2 are each provided with a number of multi-directional connection holes 3, and the number of multi-directional connection holes 3 on the first hemispherical shell 1 and the second hemispherical shell 2 are all distributed in a ring array.

[0033] Both the first hemispherical shell 1 and the second hemispherical shell 2 are equipped with positioning screws 5. The positioning screws 5 are inserted through the multi-directional connection hole 3. One end of the positioning screw 5 is provided with a screw limiting end 4, which is a cylindrical structure and has an outer diameter larger than the opening size of the multi-directional connection hole 3. A positioning nut 7 is engaged with the surface of the positioning screw 5.

[0034] In one embodiment of this utility model, the spherical connecting aluminum formwork back rib staggered positioning structure is applied to the reinforcement and positioning of the aluminum formwork 15 system on a construction site. It is particularly suitable for situations where the aluminum formwork back ribs 13 are misaligned or offset due to pre-reserved errors or construction deviations in the reserved holes 14. In actual construction, this structure can be used for positioning and reinforcement in the corner areas of the aluminum formwork 15. At corners, due to the complex splicing method and limited space, there are often problems such as inconsistent arrangement of the aluminum formwork back ribs 13 and large differences in connection height, easily forming connection gaps that cannot be directly connected. This structure can achieve rapid connection and forced tensioning of two misaligned aluminum formwork back ribs 13 under such complex working conditions.

[0035] The aluminum formwork back rib 13 serves as a profile structure to support the aluminum formwork 15. One end is fixedly installed on the aluminum formwork 15, arranged along the outer side of the formwork and exposed for easy connection. The aluminum formwork back rib 13 has pre-drilled holes 14 for through-connection, used to cooperate with external reinforcement components for positioning. When the aluminum formwork back ribs 13 in two corner areas are inconsistent in height or axially offset in the vertical or horizontal direction, a spherical connection structure can be used to achieve a compensatory connection without changing the original component arrangement.

[0036] In the specific working process, firstly, based on the relative position between the two aluminum mold back ribs 13, select the multi-directional connection hole 3 on the first hemispherical shell 1 and the second hemispherical shell 2 that is axially aligned with or closest to the reserved hole 14. Pass the two positioning screws 5 through the selected multi-directional connection holes 3 respectively, and then insert them into the corresponding reserved holes 14 on the aluminum mold back ribs 13. One end of the positioning screw 5 is provided with a screw limiting end 4, the size of which is larger than the opening size of the multi-directional connection hole 3, thus forming a stop and restriction during insertion to prevent the screw from coming out or axially moving during installation. A positioning nut 7 is provided at the end of the positioning screw 5 near the aluminum mold back rib 13. By tightening the positioning nut 7, it presses against the surface of the aluminum mold back rib 13, thereby tightening and positioning the two staggered aluminum mold back ribs 13, forming a stable reinforcement through the spherical connection structure.

[0037] The first hemispherical shell 1 and the second hemispherical shell 2 can be disassembled and connected together by bolts or snap-fit ​​connections. They can be pre-assembled into one unit according to construction requirements before installation, and can also be quickly disassembled and reused after construction. The above structure can be adapted to the connection of aluminum formwork back ribs with different directions and height differences, and is especially suitable for rapid assembly in corner areas or off-center nodes. It has the advantages of strong versatility, high positioning accuracy, and simple operation.

[0038] This invention features six multi-directional connecting holes 3 arranged in a ring array, allowing the positioning screw 5 to be flexibly inserted according to the installation position of the back rib, adapting to the connection needs of back ribs at different angles and positions, thus possessing high versatility. The cylindrical screw limiting end 4 forms a limiting fit with the non-circular connecting hole, effectively preventing axial slippage of the screw and ensuring stable connection. The positioning process requires no welding or external temporary support, significantly saving labor and accelerating template positioning efficiency, especially suitable for external corners, arcs, and irregularly shaped edges. Compared with traditional on-site welding or support rod misalignment adjustment methods, this structure has advantages such as convenient installation, reusability, structural stability, and high positioning accuracy. It can effectively reduce secondary reinforcement time and construction costs, improve on-site construction efficiency and forming quality of prefabricated buildings, and has good prospects for widespread application.

[0039] In this embodiment, a back rib clamping washer 6 is sleeved on the outer side of the positioning screw 5, and the back rib clamping washer 6 is disposed between the screw limiting end 4 and the positioning nut 7. The back rib clamping washer 6 is mainly used to form a uniform clamping force on the aluminum mold back rib 13 when the positioning nut 7 is tightened, so as to avoid point stress concentration caused by the metal nut acting directly on the back rib surface, and prevent problems such as indentation, deformation or stress fatigue cracking on the back rib surface.

[0040] By placing the back rib clamping washer 6 between the screw limit end 4 and the positioning nut 7, the position of the limit screw 5 can be stabilized during the locking process, improving the axial stability of the reinforced connection. Simultaneously, it provides buffer protection for the aluminum mold back rib 13, enhancing the long-term reliability of the overall structure. Furthermore, the washer can achieve slight sliding adjustment during the transmission of locking force, helping to precisely fit back ribs of different sizes or surface conditions, further enhancing the connection fit and universal adaptability.

[0041] In this embodiment, a first fixing block 10 is connected to the surface of the first hemispherical shell 1, and a second fixing block 9 is connected to the surface of the second hemispherical shell 2. The surfaces of the first fixing block 10 and the second fixing block 9 are respectively provided with a first connecting threaded hole 12 and a second connecting threaded hole 11, and the interiors of the first connecting threaded hole 12 and the second connecting threaded hole 11 are engaged with a hemispherical connecting bolt 8.

[0042] By setting a first fixing block 10 and a second fixing block 9 and respectively opening threaded holes, the two hemispherical shells can be detachably fastened together by hemispherical connecting bolts 8, which not only meets the requirements of strength and stability but also has good ease of assembly and disassembly. This structure is easy to pre-assemble according to site requirements before construction, can be quickly closed and positioned during installation, and can be disassembled and recycled after construction, making it easy to reuse and improving the overall economy and site adaptability of the structure.

[0043] Furthermore, placing the threaded holes on two independent fixing blocks enhances the strength of the stress-bearing areas, preventing fatigue cracking of the spherical shell or thread damage due to frequent disassembly and assembly, thereby improving the durability and long-term structural stability of the connection. Compared to integrated casting or adhesive bonding solutions, this method is more suitable for high-frequency, standardized use in construction environments.

[0044] In this embodiment, the number of multi-directional connection holes 3 on both the first hemispherical shell 1 and the second hemispherical shell 2 is six. This hole arrangement method, by uniformly setting six multi-directional connection holes 3 on each shell, allows the positioning screw 5 to flexibly select the most suitable hole position for through connection according to the actual misalignment position or installation angle between the aluminum mold back ribs 13.

[0045] This symmetrical and equally spaced arrangement enhances the versatility and flexibility of the structure in different construction scenarios, adapting to multi-directional and multi-angle connection needs. It is particularly suitable for formwork reinforcement in corner areas, irregular nodes, or space-constrained areas. Furthermore, the six-hole structure improves the mechanical balance of the connectors themselves, exhibiting high stability under stress in different directions, further ensuring the safety and reliability of the overall reinforcement system and facilitating the rapid promotion of standardized and modular construction.

[0046] In this embodiment, the first hemispherical shell 1, the second hemispherical shell 2, the screw limiting end 4, and the positioning screw 5 are all made of ferrous material. By selecting ferrous material, the structural strength and deformation resistance of the above-mentioned connecting components can be significantly improved, enabling them to maintain good dimensional stability and connection reliability during high-intensity tension, impact vibration, or repeated use.

[0047] Iron possesses excellent machinability and economy, making it suitable for mass production of complex structures. Furthermore, its surface can be enhanced with electroplating and coatings to improve corrosion resistance, adapting to long-term use in humid or dusty environments. In addition, iron components exhibit strong resistance to deformation during on-site installation, effectively ensuring the precision and stability of threaded connections, reducing loosening and breakage caused by material fatigue, and further improving the safety and service life of reinforced structures.

[0048] like Figure 1 and Figure 6 As shown, this utility model also includes a method for using a spherical connection type aluminum mold back rib staggered positioning structure, the method specifically including:

[0049] Step S1: Determine the corresponding connection path based on the actual misalignment position or offset angle between the two aluminum mold back ribs 13, and select multi-directional connection holes 3 on the first hemispherical shell 1 and the second hemispherical shell 2 respectively, corresponding to the positions of the back rib reserved holes 14.

[0050] Step S2: Pass the two positioning screws 5 through the selected multi-directional connection holes 3 respectively, and insert them through the back rib reserved holes 14 on the aluminum mold back rib 13, so that the screw limiting end 4 is limited to the outside of the hemispherical shell to prevent axial slippage.

[0051] Step S3: Fix the first hemispherical shell 1 and the second hemispherical shell 2 together by a detachable connection to form a closed connection shell structure so as to ensure stable pressurization in the future;

[0052] Step S4: On the end of the positioning screw 5 near the aluminum mold back rib 13, the back rib clamping pad 6 and the positioning nut 7 are sequentially fitted, and the positioning nut 7 is tightened so that the back rib clamping pad 6 is close to the aluminum mold back rib 13, thereby realizing the pressure positioning of the staggered aluminum mold back rib.

[0053] Step S5: After completing the back rib reinforcement work, disassemble the positioning nut 7 and the connecting parts between the housing as needed, and remove this structural component from the aluminum mold back rib 13 to achieve reuse or transfer installation;

[0054] Step S6: Repeat the above steps according to the changes in construction location to complete the back rib positioning and reinforcement operation for other staggered locations.

[0055] In this embodiment, the method for using the spherical connecting aluminum formwork back rib staggered positioning structure provided by this utility model addresses common problems in prefabricated building formwork construction, such as misalignment of aluminum formwork back ribs and misalignment of reserved holes. It offers a streamlined process for quick and easy fixing without dismantling or modifying the formwork structure. Based on multi-directional adjustable connection holes, this method achieves stable connections between back ribs at different angles and height differences through flexible hole selection, limiting insertion, spiral pressurization, and detachable shell closure. This significantly improves the adaptability of the structure and construction efficiency.

[0056] This method boasts significant advantages, including clear operational steps, strong on-site adaptability, good structural versatility, and high connection reliability. It effectively reduces the risk of rework and labor input caused by misaligned floor plans, and lowers the difficulty of intervention during construction. By employing detachable and reusable connection devices, coupled with standardized construction procedures, it not only saves material costs but also improves the forming quality and construction safety of reinforced joints.

[0057] This method is particularly suitable for rapid on-site reinforcement of prefabricated buildings, precast component installation, high-rise formwork corner areas, and complex connection nodes, and has broad engineering adaptability and promising prospects for widespread application. As the requirements for precision and efficiency in prefabricated building construction continue to increase, this method provides a practical and replicable technical solution for the intelligent and standardized connection of formwork systems.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
