It covers a wide range of fields, from residential and commercial buildings to infrastructure (such as bridges, roads, and tunnels).

[0003] In the construction process of building projects, steel pipes and plates are usually used to build scaffolding. Traditional steel pipe fasteners are usually welded from metal plates or metal pipes, and the whole is designed as a whole. They can usually only fix the steel pipes in a straight line, which is inconvenient to adjust and thus affects the actual use. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a steel pipe fastening device for construction engineering, which solves the problem that traditional steel pipe fasteners are usually welded from metal plates or metal pipes, and are designed as a whole. They can usually only fix the steel pipe in a straight line, which is inconvenient to adjust and thus affects the actual use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe fastening device for construction engineering, comprising a main connecting sleeve and a secondary connecting sleeve, wherein a main connecting member is connected to the main connecting sleeve, a secondary connecting member is connected to the secondary connecting sleeve, a first slot is provided on the secondary connecting member, a threaded sleeve is fixedly connected to the secondary connecting member, and a fixing plate is connected to both the main connecting sleeve and the secondary connecting sleeve;

[0006] The fixed plate is threaded with a fastening bolt, one end of which is rotatably connected to a clamping plate. The threaded sleeve is internally threaded with an adjusting screw, one end of which is connected to a connecting block. Two limiting rings are fixedly connected to the adjusting screw, and a gear block is rotatably connected to the adjusting screw.

[0007] As a further embodiment of this utility model: both the main connecting sleeve and the auxiliary connecting sleeve are connected to a fixing seat, the fixing seat is provided with a fixing groove, and a rubber pad is connected to the fixing seat.

[0008] As a further embodiment of this utility model: two guide rods are slidably connected to the fixing plate, and the two guide rods are respectively arranged on both sides of the fastening bolt, with one end of the guide rod connected to the clamping plate.

[0009] As a further embodiment of this utility model: the clamping plate is designed in an arc shape, and multiple rubber strips are connected to both sides of the clamping plate.

[0010] As a further embodiment of this utility model: the main connector is disposed between two secondary connectors, the main connector is rotatably connected to the threaded sleeve, and a second slot is provided on the main connector.

[0011] As a further embodiment of this utility model: the gear block is rotatably disposed between two limiting rings, the first slot corresponds to the second slot, the gear block is inserted into the first slot and the second slot, and the connecting block is provided with a hexagonal groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This steel pipe fastening device for construction projects consists of an adjusting screw, a connecting block, a main connector, a secondary connector, a threaded sleeve, a gear block, a first slot, and a second slot. When bending adjustment is required, the worker inserts an Allen wrench into the connecting block and turns the adjusting screw, causing the adjusting screw to move the gear block upwards. This causes the gear block to disengage from the second slot and engage in the first slot on the secondary connector, allowing the main connector to rotate on the threaded sleeve. This adjusts the angle between the main and secondary connectors. Then, the first and second slots are aligned, and the adjusting screw is turned again, causing the gear block to insert into both slots, thus fixing the main and secondary connectors in place and completing the adjustment. This multi-directional fastening connection of the steel pipe improves practicality.

[0014] 2. The steel pipe fastening device used in this construction project consists of a fixed plate, fastening bolts, clamps, rubber strips, and guide rods. By tightening the fastening bolts, the workers can move the clamps, causing the guide rods to slide on the fixed plate. This allows the clamps to come closer to the steel pipe, securing it in place. The rubber strips then come into contact with the steel pipe, preventing it from slipping. The device is simple to operate and easy for workers to use. Attached Figure Description

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1-5 As shown, this utility model provides a technical solution: a steel pipe fastening device for construction engineering, including a main connecting sleeve 1 and a secondary connecting sleeve 2. A main connecting member 3 is connected to the main connecting sleeve 1, and a secondary connecting member 4 is connected to the secondary connecting sleeve 2. The main connecting member 3 is disposed between the two secondary connecting members 4. The main connecting member 3 is rotatably connected to a threaded sleeve 6. A second slot 19 is provided on the main connecting member 3. By rotating the main connecting member 3 on the threaded sleeve 6, the main connecting sleeve 1 and the secondary connecting sleeve 2 can rotate, thereby facilitating the adjustment of the fastening angle by the workers according to the actual construction situation.

[0023] The secondary connector 4 has a first slot 5 and a threaded sleeve 6 fixedly connected to it. Both the main connector 1 and the secondary connector 2 are connected to a fixing plate 7. Both the main connector 1 and the secondary connector 2 are connected to a fixing seat 14. The fixing seat 14 has a fixing groove 15 and a rubber pad 16 connected to it. By screwing bolts into the fixing groove 15, the main connector 1 or the secondary connector 2 can be fixed to the ground or the plate, thereby preventing the main connector 1 or the secondary connector 2 from sliding during operation.

[0024] The fixed plate 7 is threaded with a fastening bolt 8, and two guide rods 17 are slidably connected to the fixed plate 7. The two guide rods 17 are respectively set on both sides of the fastening bolt 8. One end of the guide rod 17 is connected to the clamping plate 9. When the fastening bolt 8 is rotated to push the clamping plate 9 to move, the clamping plate 9 will drive the guide rod 17 to slide on the fixed plate 7, thereby guiding the movement of the clamping plate 9 and preventing the clamping plate 9 from rotating and deviating.

[0025] One end of the fastening bolt 8 is rotatably connected to a clamping plate 9. The clamping plate 9 has an overall arc-shaped design. Multiple rubber strips 18 are connected to both sides of the clamping plate 9. Through the arc-shaped design of the clamping plate 9, the clamping plate 9 can fit in close contact with the steel pipe. When in contact, the rubber strips 18 will be squeezed and deformed, thereby increasing friction and preventing the steel pipe from sliding.

[0026] The threaded sleeve 6 is internally threaded with an adjusting screw 10. One end of the adjusting screw 10 is connected to a connecting block 11. Two limiting rings 12 are fixedly connected to the adjusting screw 10. A gear block 13 is rotatably connected to the adjusting screw 10. The gear block 13 is rotatably positioned between the two limiting rings 12. The first slot 5 and the second slot 19 correspond to each other. The gear block 13 is inserted into the first slot 5 and the second slot 19. The connecting block 11 is provided with a hexagonal groove. By simultaneously embedding the gear block 13 into the first slot 5 and the second slot 19, the main connecting member 3 and the auxiliary connecting member 4 are combined and fixed together. The two limiting rings 12 can limit the gear block 13 and prevent the gear block 13 from sliding up and down.

[0027] The working principle of this utility model is as follows:

[0028] When making a straight connection, both steel pipes are inserted into the main connecting sleeve 1 or the auxiliary connecting sleeve 2. Then, the fastening bolt 8 is turned, causing the fastening bolt 8 to push the clamping plate 9 to move. This brings the clamping plate 9 closer to the steel pipe, causing the two clamping plates 9 to clamp and fix the steel pipe. At this time, the rubber strip 18 will be in close contact with the steel pipe, thus preventing the steel pipe from slipping. The operation is simple. When turning, the operator turns the adjusting screw 10, causing the adjusting screw 10 to drive the gear block 13 to move upward. This causes the gear block 13 to disengage from the second slot 19 and engage in the first slot 5 on the auxiliary connecting member 4. This causes the main connecting member 3 to rotate on the threaded sleeve 6, causing the main connecting sleeve 1 and the auxiliary connecting sleeve 2 to move away from each other. The included angle between the main connecting sleeve 1 and the auxiliary connecting sleeve 2 is adjusted. Then, the first slot 5 and the second slot 19 are aligned, and the adjusting screw 10 is turned, causing the gear block 13 to be inserted into the first slot 5 and the second slot 19, thus fixing the main connecting sleeve 1 and the auxiliary connecting sleeve 2 and completing the adjustment. This allows for multi-directional fastening of the steel pipe connection.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
