Abstract
Description
Technical Field
[0001] This utility model relates to the field of silo roof construction technology, and in particular to a combined support structure for tower crane sections of a silo conical roof. Background Technology
[0002] Conical silo roofs are a common structural form widely used in industrial warehousing, such as for cement, grain, and coal. The roof is shaped like a frustum or umbrella, sloping from the center outwards. This design facilitates the natural collection and drainage of materials.
[0003] However, in the construction of silo conical roofs, traditional methods typically use full-span scaffolding as the support system, which suffers from problems such as long erection periods, large material consumption, low turnover efficiency, and high construction costs. Especially in tall silo or multi-silo projects, the overall stability and load-bearing capacity of the scaffolding face severe challenges, and it is difficult to adapt to the flexible changes required by silos of different diameters. In addition, traditional support methods are cumbersome to assemble and disassemble, have poor versatility, and cannot achieve rapid assembly and repeated reuse, which restricts the improvement of construction efficiency and cost optimization. In view of this, a tower crane section combined support structure for silo conical roofs is provided to overcome the above defects. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a combined support structure for tower crane sections on a silo conical roof.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a silo conical roof tower crane section combined support structure, including a central column tower crane section, with pre-embedded anchor bolts fixedly connected to the bottom end of the central column tower crane section, a flange fixedly connected to the top end of the central column tower crane section, a splicing plate fixedly connected to the top edge of the flange, a Bailey beam fixedly connected to the inner side of the splicing plate, and pins connecting the splicing plates and the flange. An end tripod is fixedly connected to the top outer side of the Bailey beam. This structure can quickly form a high-strength, large-span central support platform, effectively replacing traditional full-span scaffolding. Furthermore, by utilizing the pin connection between the top flange and the splicing plate of the Bailey beam, rapid assembly and flexible adaptation to silos of different diameters can be achieved.
[0006] As a further description of the above technical solution: the central column tower crane section is located at the center of the silo, and a pre-embedded box is provided between the inner wall of the silo and the end tripod. The pre-embedded box is pre-embedded during the slipform construction of the inner wall of the silo, and its dimensions are 180mm deep × 200mm wide × 200mm high. Stable peripheral support is provided by the connection between the pre-embedded box in the silo wall and the end tripod.
[0007] As a further description of the above technical solution: the central column tower crane section is composed of multiple standard sections connected by high-strength bolts, and the number of pre-embedded anchor bolts is multiple, which are evenly arranged in the raft foundation of the silo.
[0008] As a further description of the above technical solution: the Bailey beam is formed by splicing a number of standardized Bailey pieces together with pins. The number of Bailey beams at the top edge of the flange is also a number, and the Bailey beams are arranged in a circle and fixed around the outside of the top of the flange to form an assembly unit. The Bailey beams can be effectively adjusted according to the change of the silo diameter and are not affected by the change of height and diameter.
[0009] As a further description of the above technical solution: there are four sets of splicing plates at the left and right ends of the Bailey beam, and the splicing plates are fixed at the top and bottom of the left end face and the top and bottom of the right end face of the Bailey beam, respectively. The splicing plates at the top of the left end face and the bottom of the right end face of the Bailey beam are at a distance from the top and bottom ends of the Bailey beam, and the distance matches the thickness of the splicing plates. Through the splicing plates at both ends of the Bailey beam, it is ensured that all transverse Bailey beams are tightly connected into an integral spatial structure, which greatly enhances the stability and load-bearing capacity of the platform.
[0010] As a further description of the above technical solution: the connection between the end tripod and the Bailey beam is through a splicing plate, and a groove is provided at the position where the inner end face of the end tripod contacts the splicing plate. The depth and cut shape of the groove are matched with the left and right lengths and cut shapes of the splicing plate. The end tripod can be used to support the connection between the Bailey beam and the inner wall of the silo, thereby improving the support force.
[0011] This utility model has the following beneficial effects:
[0012] This utility model designs a silo conical roof tower crane section combined support structure. Through the design and coordination of standard tower crane sections as the central column and modular Bailey beams arranged radially, the device can quickly form a high-strength, large-span central support platform, effectively replacing traditional full-span scaffolding. The top flange and the splicing plates of the Bailey beams are connected by pins, enabling rapid assembly and flexible adaptation to silos of different diameters. Stable peripheral support is provided by the pre-embedded boxes in the silo walls and the insertion of end tripods. The splicing plates at both ends of the Bailey beams ensure that all transverse Bailey beams are tightly connected into an integral spatial structure, greatly enhancing the platform's stability and load-bearing capacity. Furthermore, the use of standard parts and standardized connection methods significantly improves the device's versatility, reusability, and assembly / disassembly efficiency, greatly reducing construction costs. It is particularly suitable for the construction of conical roofs in tall silo and multi-silo projects. Attached Figure Description
