Description

Technical Field

[0001] This utility model relates to the field of frame structure technology, specifically a novel precast monolithic multi-layer frame structure. Background Technology

[0002] Precast monolithic multi-layer frame structures are a composite structural system in modern construction that integrates the advantages of precast assembly and on-site casting. This structure uses precast concrete columns, beams, and other components as the main frame. Standardized factory production ensures the dimensional accuracy and mechanical properties of the components before they are transported to the construction site for hoisting and assembly. At key connection nodes, a post-cast concrete monolithic casting process is used to tightly integrate the precast components with the core area of ​​the node, forming a unified load-bearing frame system, effectively improving the structure's integrity and seismic performance.

[0003] Traditional systems rely heavily on a single construction method of on-site casting. The size of components is limited by the formwork and is difficult to adjust flexibly. Furthermore, the connection between components often uses simple welding, which makes it difficult to achieve flexible splicing when the structure is modified or expanded in the later stages. To address this, we propose a new type of precast monolithic multi-layer frame structure. Utility Model Content

[0004] The purpose of this utility model is to provide a novel precast monolithic multi-layer frame structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel precast monolithic multi-layer frame structure includes a first fixing frame, a first mounting hole, a connecting rod, a second fixing frame, a second mounting hole, and a first protrusion. The first fixing frame has a plurality of first mounting holes on one side, and the connecting rod is threadedly connected to the interior of the plurality of first mounting holes. The other end of the connecting rod is provided with a second fixing frame. The second fixing frame has a plurality of second mounting holes on one side, and the other end of the connecting rod is threadedly connected to the second mounting holes. A first protrusion is fixedly provided at one end of the first fixing frame.

[0007] The first protrusion has a first threaded groove on its top, and the second bracket has a second protrusion fixedly mounted on one end.

[0008] The second protrusion has a second threaded groove on its top, and the first fixing bracket has a first slot on its other end.

[0009] The first slot has a first fixing screw hole at the top and a second fixing screw hole at the bottom.

[0010] The second fixing bracket has a second slot at the other end, and a third fixing screw hole at the top of the second slot.

[0011] The second slot has a fourth fixing screw hole at the bottom, and the first protrusion matches the first slot.

[0012] The second protrusion and the second slot are matched. The top and bottom of the first fixing frame are provided with first connecting holes, and the first connecting hole is internally threaded with a first connecting post. The top and bottom of the second fixing frame are provided with several second connecting holes, and the internal connecting holes are internally threaded with second connecting posts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This novel precast, monolithic, multi-layered frame structure uses a first fixed frame and a second fixed frame as basic load-bearing units, connected laterally for stability via connecting rods. The connecting rods are threaded to the first mounting holes of the first fixed frame and the second mounting holes of the second fixed frame, respectively, forming independent frame units. Simultaneously, the first protrusion of the first fixed frame matches the first slot of the adjacent first fixed frame, and the second protrusion of the second fixed frame matches the second slot of the adjacent second fixed frame. After assembly, the joints are secured with bolts through the fixing screw holes at the top and bottom of the slots, ensuring no loosening of the nodes during lateral expansion and achieving uniform load distribution. This not only guarantees the integrity and stability of the overall structure but also enables efficient construction and flexible expansion through the standardized interfaces of the precast components.

[0015] 2. This novel precast monolithic multi-layer frame structure achieves layer extension through the cooperation of connecting holes and connecting columns in terms of longitudinal multi-layer construction and functional expansion. The first connecting holes at the top and bottom of the first fixed frame are internally threaded to the first connecting column, and the second connecting holes of the second fixed frame are internally connected to the second connecting column. The multi-layer structure is completed by docking the connecting columns with the corresponding interfaces of the upper and lower frame layers. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution:

[0023] A novel precast monolithic multi-layer frame structure includes a first fixing frame 1, a first mounting hole 2, a connecting rod 3, a second fixing frame 4, a second mounting hole 5, and a first protrusion 6. The first fixing frame 1 has several first mounting holes 2 on one side, and the connecting rod 3 is threadedly connected to the inside of the several first mounting holes 2. The other end of the connecting rod 3 is provided with a second fixing frame 4. The second fixing frame 4 has several second mounting holes 5 on one side, and the other end of the connecting rod 3 is threadedly connected to the second mounting holes 5. The first protrusion 6 is fixedly provided at one end of the first fixing frame 1.

[0024] The first fixing bracket 1 and the second fixing bracket 4 are manufactured using an integrated prefabrication process, forming a rectangular frame structure. Several first mounting holes 2 are evenly distributed horizontally on one side, with standard threads inside the hole walls to form a tight threaded connection with the connecting rod 3, ensuring no loosening under lateral force. The end design of the first fixing bracket 1 exhibits bidirectional splicing characteristics: one end features an integrally formed first protrusion 6, with a deep threaded groove 7 on the top of the protrusion; the other end has a first slot 10 precisely matching the size of the first protrusion 6, with the inner wall of the slot precision-machined to ensure a snug fit. Furthermore, the end design of the second fixing bracket 4 is identical to that of the first fixing bracket 1.

[0025] The first protrusion 6 has a first threaded groove 7 on its top. The second bracket 4 has a second protrusion 8 fixedly mounted on one end. The second protrusion 8 has a second threaded groove 9 on its top. The first bracket 1 has a first slot 10 on its other end. The first slot 10 has a first fixing screw hole 11 on its top and a second fixing screw hole 12 on its bottom. The second bracket 4 has a second slot 13 on its other end. The second slot 13 has a third fixing screw hole 14 on its top and a fourth fixing screw hole 15 on its bottom. The first protrusion 6 and the first slot 10 are matched. The second protrusion 8 and the second slot 13 are matched. The first bracket 1 has a first connecting hole 16 on its top and bottom. The first connecting hole 16 is threadedly connected to a first connecting post 17. The second bracket 4 has several second connecting holes 18 on its top and bottom. The second connecting holes 18 are threadedly connected to second connecting posts 19.

[0026] The connecting rod 3 is a high-strength alloy screw with a thread length of ≥50mm at both ends to ensure effective engagement length with the mounting hole; the first connecting post 17 and the second connecting post 19 are both capped screws with galvanized anti-rust treatment on the surface of the post body. The top nut has an internal hexagonal groove to facilitate quick tightening with tools, achieving precise docking and load transfer between the upper and lower shelves.

[0027] In this embodiment, a novel precast monolithic multi-layer frame structure is used. First, the first fixed frame 1 and the second fixed frame 4 serve as basic load-bearing units, achieving a stable lateral connection through connecting rods 3. The two ends of the connecting rods 3 are threaded to the first mounting holes 2 of the first fixed frame 1 and the second mounting holes 5 of the second fixed frame 4, respectively, forming independent frame units. Simultaneously, the first protrusion 6 of the first fixed frame 1 matches the first slot 10 of the adjacent first fixed frame 1, and the second protrusion 8 of the second fixed frame 4 matches the second slot 13 of the adjacent second fixed frame 4. After splicing, they are secured with bolts through the fixing screw holes at the top and bottom of the slots, ensuring no loosening of the nodes during lateral expansion and achieving uniform load distribution. This ensures both the integrity and stability of the overall structure and achieves efficient construction and flexible expansion through the standardized interfaces of the precast components. Then, in terms of longitudinal multi-layer construction and functional expansion, the structure achieves layer extension through the cooperation of connecting holes and connecting columns. The first connecting hole 16 at the top and bottom of the first fixing frame 1 is internally threaded to the first connecting post 17, and the second connecting hole 18 of the second fixing frame 4 is internally connected to the second connecting post 19. The multi-layer structure is completed by connecting the connecting post to the corresponding interface of the upper and lower layer frames.
