Description

Technical Field

[0001] The utility model relates to the technical field of square steel pipes, in particular to a square steel pipe with an internal reinforcement structure. Background Art

[0002] In many fields such as construction engineering, bridge structures, water conservancy facilities and offshore platforms, steel structures are widely used due to their high strength, high toughness and good durability. As an important component of steel structures, square steel tubes have become an indispensable structural material in the above fields due to their regular cross-sectional shape and easy processing and connection.

[0003] However, in actual use, square steel tubes often need to work under large loads or complex stress conditions, which puts higher demands on the strength and stability of square steel tubes. Traditional square steel tube designs mainly rely on increasing material thickness or using more expensive alloy materials to improve their load-bearing capacity, but these methods not only increase manufacturing costs, but may also bring about problems such as increased processing difficulty. Therefore, a square steel tube with an internal reinforced structure is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the existing technology that rely on increasing the material thickness or using more expensive alloy materials to improve the bearing capacity of square steel tubes, resulting in increased manufacturing costs and possible increased processing difficulty, and to propose a square steel tube with an internal reinforced structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A square steel pipe with an internal reinforcement structure comprises a square steel pipe body, a reinforcing steel pipe is provided inside the square steel pipe body for structural reinforcement of the square steel pipe body, and a connecting mechanism is provided on the top of the inner wall of the square steel pipe body for connecting the reinforcing steel pipe;

[0007] The connecting mechanism includes a snap-fit sleeve, which is snap-fitted to the top of the inner wall of the square steel tube body. The top of the snap-fit sleeve is fixedly connected to a limiting cover plate. The inner walls on both sides of the snap-fit sleeve are fixedly connected to the same connecting rod. The bottom of the inner wall of the square steel tube body is provided with a locking mechanism for fixing the reinforcing steel pipe.

[0008] In one possible design, the locking mechanism includes a snap-fit block, which is snap-fitted to the bottom of the inner wall of the square steel tube body, and the bottom of the snap-fit block is fixedly connected to a limiting cover plate 2, and the top of the snap-fit block is provided with a receiving groove 1, and the circumferential inner wall of the receiving groove 1 is provided with multiple limiting grooves, and the bottom of the snap-fit block is provided with a receiving groove 2, and the top inner wall of the receiving groove 2 is provided with a through limiting hole, and the top of the limiting hole is connected to the bottom of the receiving groove 1.

[0009] In a possible design, a sliding groove is provided on the top of the reinforced steel pipe, a rotating groove perpendicular to the sliding groove is provided at the bottom of the sliding groove, a fixed groove parallel to the sliding groove is provided on one side of the top of the rotating groove, the sliding groove, rotating groove and fixed groove are connected to each other, the sliding groove, rotating groove and fixed groove are adapted to the connecting rod, and a plurality of limit blocks are fixedly connected to the bottom of the circumferential outer wall of the reinforced steel pipe, and the limit blocks are adapted to the limit grooves.

[0010] In a possible design, a hexagon socket bolt is rotatably connected in the second receiving groove, and the threaded portion of the hexagon socket bolt is threadedly connected to the bottom center of the reinforcing steel pipe.

[0011] In a possible design, a through hole is opened at the center of the second limiting cover plate, and a second limiting ring is fixedly connected in the through hole to prevent the hexagon socket bolt from falling off.

[0012] In one possible design, the circumferential outer wall of the reinforced steel pipe is fixedly connected with multiple limit rings 1, and the circumferential outer wall of the reinforced steel pipe is snap-connected with multiple reinforcement blocks, the reinforcement blocks are located between two corresponding limit rings 1, and the reinforcement blocks are adapted to the square steel pipe body.

[0013] In this application, when people need to strengthen the structure of the square steel pipe body, first, the reinforcement block is engaged between the two corresponding limit rings fixedly connected on the circumferential outer wall of the reinforcement steel pipe, and at the same time, the locking mechanism and the reinforcement steel pipe are connected together through the hexagon socket bolt and the bottom thread of the reinforcement steel pipe. Then, the reinforcement steel pipe is inserted into the square steel pipe body and the locking mechanism is engaged with the bottom of the square steel pipe body. Then, the hexagon socket bolt is turned with an hexagon socket wrench to push the reinforcement steel pipe upward along the limit groove so that the top of the reinforcement steel pipe is exposed. Then, the reinforcement steel pipe is engaged with the connecting rod of the connecting mechanism through the sliding groove, rotating groove and fixing groove opened on the top. Then, the hexagon socket bolt is rotated in the opposite direction to move the reinforcement steel pipe downward through the thread, and the connecting rod is pulled through the fixing groove to move the connecting mechanism downward as a whole and engage with the top of the square steel pipe body to complete the structural reinforcement of the square steel pipe body.

[0014] In the present invention, the square steel tube with an internal reinforcement structure directly increases the internal stress-bearing area of the square steel tube body by using the internal reinforcement steel tube as the core reinforcement member, effectively dispersing the external load, thereby significantly improving the bearing capacity of the square steel tube body. This allows the square steel tube body to remain stable under heavy loads or complex stress conditions, thereby extending its service life.

[0015] In the utility model, the square steel tube with an internal reinforcement structure adopts a combined design of a snap-fit sleeve and a connecting rod as the connection mechanism, which not only realizes a stable connection between the reinforced steel tube and the top of the square steel tube body, but also facilitates installation and disassembly, thereby improving construction efficiency. At the same time, the locking mechanism ensures that the reinforced steel tube is firmly fixed to the bottom of the square steel tube body through the cooperation of the snap-fit block, the limiting groove and the limiting block, thereby preventing the reinforced steel tube from shifting or falling off.

[0016] In the present invention, the square steel tube with an internal reinforcement structure, compared with the traditional method of relying on increasing the material thickness or using expensive alloy materials, the present invention improves the load-bearing capacity of the square steel tube without significantly increasing the material consumption through the design of the internal reinforcement structure, thereby effectively reducing the manufacturing cost of the square steel tube;

[0017] In the present invention, the internally arranged reinforcing steel pipe is used as the core reinforcing component, which directly increases the stress-bearing area inside the square steel pipe body, effectively disperses the external load, and thus significantly improves the bearing capacity of the square steel pipe body. This enables the square steel pipe body to remain stable when subjected to large loads or complex stress states, thereby extending its service life. The connecting mechanism adopts a combination design of a snap-fit sleeve and a connecting rod, which not only achieves a firm connection between the reinforcing steel pipe and the top of the square steel pipe body, but also facilitates installation and disassembly, thereby improving construction efficiency. At the same time, the locking mechanism ensures the firm fixation of the reinforcing steel pipe at the bottom of the square steel pipe body through the cooperation of the snap-fit block, the limit groove and the limit block, thereby preventing the reinforcing steel pipe from shifting or falling off. Compared with the traditional method of relying on increasing the material thickness or using expensive alloy materials, the present invention achieves an improvement in the bearing capacity of the square steel pipe without significantly increasing the material usage through the design of the internal reinforcing structure, thereby effectively reducing the manufacturing cost of the square steel pipe.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1

[0025] Reference Figures 1-4 A square steel pipe comprises a pipe body 1, which is shaped like a standard square tube. A reinforcing steel pipe 2 is designed and installed inside the pipe body 1 to enhance the rigidity and load-bearing capacity of the overall structure. The diameter of the reinforcing steel pipe 2 is slightly smaller than the inner diameter of the pipe body 1 to facilitate smooth installation.

[0026] A snap-fit sleeve 31 is mounted on the top of the inner wall of the square steel pipe body 1. A limit plate 32 is fixedly attached to the top of the snap-fit sleeve 31 to prevent vertical movement of the reinforcing steel pipe 2. Connecting rods 33 are also fixedly attached to the inner walls of both sides of the snap-fit sleeve 31 to engage with the specific structure at the top of the reinforcing steel pipe 2.

[0027] The top of the reinforcing steel tube 2 is provided with a sliding groove 21, and the bottom of the sliding groove 21 further provides a rotation groove 22 perpendicular to the sliding groove 21. A fixed groove 23, parallel to the sliding groove 21, is also provided on one side of the top of the rotation groove 22. These three grooves are interconnected, forming a unique track structure. When the reinforcing steel tube 2 is installed inside the square steel tube body 1, the connecting rod 33 first enters the sliding groove 21, then rotates into the rotation groove 22, and finally secures in the fixed groove 23, thereby achieving a stable connection at the top of the reinforcing steel tube 2.

[0028] A locking mechanism 4 is provided at the bottom of the inner wall of the square steel pipe body 1. This mechanism includes a snap-fit block 41, the bottom of which is fixedly connected to a second limiting cover plate 42, which is used to prevent the reinforcing steel pipe 2 from moving at the bottom. A receiving groove 1 44 is provided at the top of the snap-fit block 41, which is used to accommodate the bottom of the reinforcing steel pipe 2. The circumferential inner wall of the receiving groove 1 44 is provided with a plurality of limiting grooves 45, which are adapted to the limiting block 24 at the bottom of the circumferential outer wall of the reinforcing steel pipe 2. At the same time, a second receiving groove 46 is also provided at the bottom of the snap-fit block 41, and a through limiting hole 47 is provided on the top inner wall of the receiving groove 2 46, and the top of the limiting hole 47 is connected to the bottom of the receiving groove 1 44.

[0029] Insert the bottom of the reinforcing steel pipe 2 into the first receiving groove 44, so that the limit block 24 engages with the limit groove 45. Then, rotate and connect a hexagon socket bolt 7 in the second receiving groove 46, and the threaded portion of the bolt is threadedly connected to the center of the bottom of the reinforcing steel pipe 2, thereby further locking the reinforcing steel pipe 2.

[0030] This application can be used in the field of square steel pipes, and can also be used in other fields applicable to this application.

[0031] Example 2

[0032] refer to Figures 1-4 Based on the first embodiment, an improvement is provided: a square steel pipe with an internal reinforcement structure, which is applied to the field of square steel pipes. Multiple retaining rings 5 are fixedly connected to the circumferential outer wall of the reinforcing steel pipe 2. These retaining rings 5 are evenly spaced and used to support and position subsequent reinforcing blocks 6. Subsequently, multiple reinforcing blocks 6 are engaged and connected between two corresponding retaining rings 5. The shape and size of these reinforcing blocks 6 match the inner wall of the square steel pipe body 1, thereby increasing the contact area between the reinforcing steel pipe 2 and the square steel pipe body 1, further improving the stability and strength of the overall structure.

[0033] To prevent the hexagon socket bolt 7 from falling off during use, a through hole is provided at the center of the second limiting cover plate 42, and a second limiting ring 43 is fixedly connected to the through hole. The inner diameter of the second limiting ring 43 is slightly smaller than the head diameter of the hexagon socket bolt 7, thereby effectively preventing the bolt from accidentally falling off.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
