Description

Technical Field

[0001] This utility model belongs to the field of grain silo technology, and in particular relates to a reusable grain silo wall steel bar spacing control device. Background Technology

[0002] Grain silos are cylindrical, vertical storage facilities used for large-scale grain storage. They are mainly used for the centralized storage of agricultural products such as wheat, corn, and rice. Their core function is to inhibit pests and mold growth through a sealed structure and environmental control system (such as ventilation and temperature and humidity monitoring), ensuring the stable quality of grain during long-term storage. Typical applications include port transshipment warehouses, national grain reserve bases, and raw material warehouses for large processing enterprises (such as flour mills and feed mills). They are characterized by large single-silo capacity (up to 10,000 tons), high mechanization rate (with supporting conveying and cleaning equipment), and excellent space utilization, making them an indispensable storage and transportation hub in the modern grain industry chain.

[0003] In existing grain silo wall reinforcement construction, a combination of cement spacers and welded steel reinforcement cages is commonly used to control the spacing of the steel bars and the thickness of the protective layer. However, this approach has the following drawbacks: First, cement spacers are labor-intensive, fragile, and prone to being missed during construction, seriously affecting construction efficiency and quality. Second, the construction difficulty of the welded steel reinforcement cage increases with the slipform height, leading to reduced work efficiency and a longer concrete pouring interval, which can easily form cold joints, affecting the integrity and airtightness of the silo structure. Third, the spacing between the outermost layer of steel bars in the welded cage and the formwork is small, making it easy for scraping to occur during slipform construction, affecting the appearance quality of the concrete.

[0004] Based on this, this utility model designs a reusable grain silo wall steel bar spacing control device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing methods in grain silo wall reinforcement construction. These methods typically combine cement blocks with welded steel reinforcement frames to control reinforcement spacing and protective layer thickness. Firstly, cement blocks are labor-intensive, fragile, and prone to incomplete binding, severely impacting construction efficiency and quality. Secondly, the difficulty of constructing the welded steel reinforcement frame increases with the slipform height, leading to reduced work efficiency and prolonged concrete pouring intervals, which can cause cold joints and affect the overall integrity and airtightness of the silo structure. Thirdly, the small spacing between the outermost layer of welded reinforcement and the formwork makes it susceptible to scraping during slipform construction, affecting the appearance quality of the concrete. Therefore, this invention proposes a reusable grain silo wall reinforcement spacing control device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reusable device for controlling the spacing of steel bars on the wall of a grain silo, comprising a positioning circumferential pipe, a connecting rod, a sliding pipe clamp assembly and a fixing bracket. The positioning circumferential pipe is divided into an inner ring and an outer ring, and is arranged circumferentially along the wall of the silo. Both ends of the connecting rod are respectively connected to the positioning circumferential pipes of the inner ring and the outer ring. One end of the sliding pipe clamp assembly is connected to the positioning circumferential pipe, and the other end is connected to the vertical steel bar, and the connection angle between the two is adjustable. The fixing bracket is connected to the sliding formwork device and supports the positioning circumferential pipe, so that the positioning circumferential pipe slides up synchronously with the sliding formwork. The positioning circumferential pipe, the sliding pipe clamp assembly and the connecting rod are of a detachable and assembled structure.

[0008] As a further description of the above technical solution:

[0009] The positioning circumferential pipe is composed of multiple single pipes connected by screw threads to form an annular structure.

[0010] As a further description of the above technical solution:

[0011] Both ends of the connecting rod are respectively connected to the positioning circumferential pipes of the inner ring and the outer ring through pipe clamps.

[0012] As a further description of the above technical solution:

[0013] The sliding pipe clamp assembly includes two pipe clamps connected by bolts. One of the pipe clamps is fixed to the positioning circumferential pipe, and the other pipe clamp is fixed to the vertical steel bar.

[0014] As a further description of the above technical solution:

[0015] The fixing bracket is in a shape of a capital "J", and its upper part is provided with a U-shaped ring for lifting the positioning circumferential pipe.

[0016] As a further description of the above technical solution:

[0017] The length of the single pipe of the positioning circumferential pipe is 1.5m, 3m, 4.5m or 6m.

[0018] As a further description of the above technical solution:

[0019] The bottom of the fixing bracket is welded and fixed to the sliding formwork.

[0020] As a further description of the above technical solution:

[0021] The connection between the sliding pipe clamp assembly and the positioning circumferential pipe is a detachable connection.

[0022] To sum up, due to the adoption of the above technical solution, the beneficial effects of the present utility model are:

[0023] This invention achieves efficient and repeatable control over the spacing of vertical reinforcing bars and the thickness of the protective layer in a silo by setting up a positioning ring pipe (divided into an inner and outer ring) composed of polypropylene plastic pipes, a connecting rod, a sliding pipe clamp assembly, and a fixed bracket that can slide with the slipform. During construction, plastic pipes of appropriate length are selected according to the silo diameter and assembled into inner and outer ring positioning pipes. The distance between the fixed rings is connected by the connecting rod. One end of the sliding pipe clamp assembly is clamped to the positioning ring pipe, and the other end clamps the vertical reinforcing bars. The installation angle is adjustable to adapt to different reinforcing bar arrangements. The fixed bracket is installed on the slipform template, and its top is equipped with a "U"-shaped support ring, which lifts the entire positioning system synchronously during the slipform's ascent. This device has a simple structure, is easy to install, and is highly reusable. It not only eliminates the traditional construction process of cement blocks and welded frames, improving construction efficiency and the accuracy of vertical reinforcing bar positioning, but also avoids the problem of template scraping the reinforcing bars, improves the appearance quality of the concrete surface, and ensures the overall airtightness of the silo structure.

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 ,

[0032] This utility model provides a technical solution: a reusable grain silo wall reinforcement spacing control device, including a positioning circumferential tube 1, a connecting rod 2, a sliding pipe clamp assembly 3, and a fixed bracket 4. The positioning circumferential tube 1 is divided into an inner ring and an outer ring, which are arranged circumferentially along the silo wall. The two ends of the connecting rod 2 are respectively connected to the positioning circumferential tubes 1 of the inner ring and the outer ring. The two ends of the connecting rod 2 are respectively connected to the positioning circumferential tubes 1 of the inner ring and the outer ring through pipe clamps to form a rigid connection structure, which effectively limits the spacing between the inner and outer positioning tubes, thereby controlling the overall width of the circumferential positioning system and ensuring the stable positioning foundation of the vertical reinforcement.

[0033] The sliding pipe clamp assembly 3 is connected to the positioning ring pipe 1 at one end and the vertical reinforcing bar at the other end, and the connection angle between the two is adjustable. The fixed bracket 4 is connected to the sliding template device and supports the positioning ring pipe 1 so that the positioning ring pipe 1 slides up synchronously with the sliding template. The positioning ring pipe 1, the sliding pipe clamp assembly 3 and the connecting rod 2 are detachable and assembleable structures. The pipe clamp in the sliding pipe clamp assembly 3 clamps the vertical reinforcing bar with bolts, so that the reinforcing bar can be quickly positioned and stably maintain its vertical spacing under the constraint of the positioning ring pipe 1, avoiding the error of manual visual inspection and effectively improving the vertical accuracy and consistency of the reinforcing bar layout.

[0034] Specifically, such as Figures 2-4 As shown, the positioning ring tube 1 is composed of multiple single tubes connected by threaded threads to form a ring structure. The two ends of the connecting rod 2 are connected to the inner and outer ring positioning ring tubes 1 respectively by tube clamps. The sliding tube clamp assembly 3 includes two tube clamps connected by bolts. One tube clamp is fixed to the positioning ring tube 1, and the other tube clamp is fixed to the vertical steel bar. The fixing bracket 4 is shaped like a "Z" and has a U-shaped ring at the top for supporting the positioning ring tube 1. The "U"-shaped ring is set at the top of the fixing bracket 4 to support the positioning ring tube 1 from below, so that the positioning tube does not sink or shift during the sliding process, thereby ensuring that the steel bar positioning structure can always maintain a consistent height and coaxial position during the vertical sliding process.

[0035] The single pipe length of the positioning ring pipe 1 is 1.5m, 3m, 4.5m or 6m. The bottom of the fixed bracket 4 is welded and fixed to the sliding template. The connection between the sliding pipe clamp assembly 3 and the positioning ring pipe 1 is a detachable connection.

[0036] Working principle and usage: By setting up a positioning ring pipe 1 (divided into inner and outer rings) composed of polypropylene plastic pipes, a connecting rod 2, a sliding pipe clamp assembly 3, and a fixed support 4 that can slide with the slipform, efficient and repeatable control of the spacing of vertical reinforcement bars and the thickness of the protective layer in the silo can be achieved. During construction, plastic pipes of appropriate length are selected according to the silo diameter and assembled into inner and outer ring positioning pipes. The distance between the fixed rings is connected by the connecting rod 2. One end of the sliding pipe clamp assembly 3 is clamped to the positioning ring pipe 1, and the other end clamps the vertical reinforcement bars. The installation angle is adjustable to adapt to different reinforcement bar arrangements. The fixed support 4 is installed on the slipform template and has a "U"-shaped support ring at the top. During the rise of the slipform, it lifts the entire positioning system and raises it synchronously. This device has a simple structure, is easy to install, and has strong reusability. It not only eliminates the construction process of traditional cement blocks and welded skeletons, improving construction efficiency and the accuracy of vertical reinforcement bar positioning, but also avoids the problem of the template scraping the reinforcement bars, improves the appearance quality of the concrete surface, and ensures the overall airtight performance of the silo structure.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
