Description

Technical Field

[0001] This utility model belongs to the technical field of grain storage building structure, specifically relating to a shallow circular silo roof gutter and ring beam assembly structure. Background Technology

[0002] Shallow circular silos are cylindrical above-ground grain silos with a height-to-diameter ratio of less than 1.5. Primarily used for grain storage, they are characterized by large single-silo capacity, small footprint, and structural stability. This type of grain silo was introduced to China in the 1990s through a World Bank loan project. The traditional method for constructing the roof platform of a shallow circular silo involves pre-reserving openings in the silo wall, passing platform crossbars through these openings, and then laying platform panels on the crossbars. This method requires pre-reserving openings in the silo wall, which are difficult to seal later and pose a significant risk of leakage. Grain silos have extremely high requirements for airtightness and impermeability. To prevent such problems, a triangular platform method with pre-embedded prefabricated connectors was studied. Therefore, we propose an assembled structure for the roof gutter and ring beam of a shallow circular silo. Utility Model Content

[0003] The purpose of this utility model is to provide a shallow circular silo roof gutter and ring beam assembly structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a shallow circular silo roof gutter and ring beam assembly structure, including a shallow circular silo sidewall. A positive threaded sleeve is symmetrically embedded on both the inner and outer sides of the shallow circular silo sidewall. Two sets of threaded steel bars are welded side-by-side on the upper and lower sides of the positive threaded sleeve. The threaded steel bars are embedded and pass through the inner side of the shallow circular silo sidewall. The threaded steel bars and the positive threaded sleeve are arranged circumferentially around the silo wall. A round steel bar is provided on one side of the positive threaded sleeve. One end of the round steel bar is threadedly fixed to the positive threaded sleeve through a threaded connection. A horizontal steel pipe is sleeved on the outer side of one end of the round steel bar, and the surface of the horizontal steel pipe is fixedly welded to the surface of the round steel bar.

[0005] Preferably, the end of the horizontal steel pipe near the side wall of the shallow circular silo is vertically fixed to a vertical steel pipe by fasteners, and the end of the horizontal steel pipe away from the side wall of the shallow circular silo and the bottom end of the vertical steel pipe are both fixedly connected to inclined steel pipes by fasteners.

[0006] Preferably, the horizontal steel pipes, vertical steel pipes, and inclined steel pipes are arranged in a circumferential manner around the inner and outer sides of the silo wall.

[0007] Preferably, a scaffolding is laid in a ring above the horizontal steel pipe.

[0008] Preferably, a vertical guardrail is vertically fixed to one end of the horizontal steel pipe away from the side wall of the shallow circular silo using fasteners, and a fence rod is fixedly connected in a ring between the vertical guardrails.

[0009] Preferably, a dustproof net and a safety net can be suspended between the horizontal steel pipe and the vertical guardrail.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The device uses a pre-embedded positive thread sleeve to fix the round steel in place, and is then welded to a pre-set triangular frame. It is arranged in a ring around the inner and outer sides of the silo wall to complete the construction of the operating platform. Compared with the traditional triangular operating platform, this method can effectively eliminate the safety and quality hazards caused by leaving through-wall holes and reduce construction costs.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a shallow circular silo roof gutter and ring beam assembly structure, including a shallow circular silo sidewall 1, with positive thread sleeves 3 symmetrically embedded on the inner and outer sides of the shallow circular silo sidewall 1, and two sets of threaded steel bars 2 welded side by side on the upper and lower sides of the positive thread sleeves 3. The threaded steel bars 2 are embedded and pass through the inner side of the shallow circular silo sidewall 1. The threaded steel bars 2 and the positive thread sleeves 3 are arranged in a circumferential manner around the silo wall. A round steel bar 4 is provided on one side of the positive thread sleeve 3. One end of the round steel bar 4 is threadedly fixed to the positive thread sleeve 3 through the provided thread. A horizontal steel pipe 5 is sleeved on the outer side of one end of the round steel bar 4. The surface of the horizontal steel pipe 5 and the round steel bar 4 are fixedly welded.

[0018] Specifically, the end of the horizontal steel pipe 5 closest to the side wall 1 of the shallow circular silo is vertically fixed to the vertical steel pipe 6 by fasteners, and the end of the horizontal steel pipe 5 away from the side wall 1 of the shallow circular silo and the bottom end of the vertical steel pipe 6 are both fixedly connected to the inclined steel pipe 7 by fasteners.

[0019] Specifically, the horizontal steel pipe 5, the vertical steel pipe 6, and the diagonal steel pipe 7 are arranged in a ring around the inner and outer sides of the warehouse wall.

[0020] Specifically, a scaffolding board 9 is laid in a ring above the horizontal steel pipe 5.

[0021] Specifically, a vertical guardrail 8 is vertically fixed to one end of the horizontal steel pipe 5 away from the side wall 1 of the shallow circular silo via fasteners, and a fence post 10 is fixedly connected in a ring between the vertical guardrails 8.

[0022] Specifically, dustproof netting and safety netting can be suspended between the horizontal steel pipe 5 and the vertical guardrail 8.

[0023] In this embodiment, the threaded steel bars 2 are welded side by side to the outside of the positive threaded sleeve 3. The inside of the positive threaded sleeve 3 is filled with grease and then sealed with tape. Its inner side is welded shut to prevent concrete from entering. The sleeve is pre-embedded in the concrete under the bottom of the lower ring beam by the slipform. The pre-embedded part is removed and cleaned using the slipform's finishing hanger. Then, the round steel bar 4 with threaded ends is connected to the positive threaded sleeve 3 and tightened with a threading wrench. The inner and outer sides of the shallow circular chamber are consistent. The horizontal steel pipe 5, vertical steel pipe 6 and inclined steel pipe 7 are used to connect them in advance. After connecting the triangular frame, the horizontal steel pipe 5 is inserted into the outside of the round steel 4 and spot welded to prevent the steel pipe triangular frame from slipping. The construction of the inner and outer platforms is consistent. After the triangular frame is completed, the slipform scaffolding plank 9 is used to flip it up onto the triangular frame platform to make a ring beam construction platform. After laying the plank 9 on the top of the triangular frame, the vertical guardrail 8 and the fence post 10 are built at one end of the horizontal steel pipe 5 using fasteners to achieve a protective effect. Finally, dustproof nets and safety nets can be hung between the vertical guardrail 8 and the fence post 10. Multiple sets of triangular frames are arranged around the warehouse wall.
