Description

Technical Field

[0001] This utility model relates to the field of steel structures, and in particular to a modular prefabricated steel structure. Background Technology

[0002] Steel structure is a building structure that uses steel as the main load-bearing material and is connected by steel. It has been widely used in special buildings such as bridges, towers, and stadiums.

[0003] When using steel structures, the first and second steel frames come into contact, and then the first bolt is used to connect and fix the contacting first and second steel frames to complete the modular assembly of the steel structure. When the second steel frame comes into contact with the first steel frame, it is not precisely positioned, requiring continuous support to ensure it does not shift during assembly. At this point, the first bolt is used to fix the first and second steel frames together, but without proper positioning, this process introduces certain instability and error risks, potentially leading to problems that affect the overall assembly effect of the steel structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is that when the second steel frame comes into contact with the first steel frame, the second steel frame is not accurately positioned, which requires continuous support for the second steel frame to ensure that it does not shift during assembly. At this time, the first bolt is used to fix the first steel frame and the second steel frame together. However, without positioning, this process has certain instability and error risk, which leads to problems that affect the assembly effect of the steel structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a modular prefabricated steel structure, including a first steel frame and a second steel frame. A plurality of first bolts are provided on one side of the first steel frame. The first bolts are inserted into the surface of the first steel frame to connect with the second steel frame. A positioning device is provided on one side of the first steel frame to position the connection between the first steel frame and the second steel frame.

[0006] Preferably, the positioning device includes a mounting plate, a second bolt, a placement plate, a bracket, a spring, a positioning frame, and positioning holes formed on the second steel frame. The mounting plate is disposed on the surface of the first steel frame. The second bolt is inserted into one side of the mounting plate to connect with the placement plate. The bracket is disposed on one side of the placement plate. The two ends of the spring are respectively connected to the bracket and the positioning frame. The two ends of the positioning frame penetrate the placement plate and are inserted into the positioning holes on one side of the second steel frame to position the second steel frame.

[0007] Preferably, the telescopic rod is sleeved inside the spring, and both ends of the telescopic rod are connected to the bracket and the positioning frame.

[0008] Preferably, the positioning frame has inclined slots at both ends, and the inclined slots at both ends of the positioning frame are close to the second steel frame.

[0009] Preferably, the inclined groove areas at both ends of the positioning frame are provided with a number of ball bearings to reduce the contact area between the inclined grooves at both ends of the positioning frame and the second steel frame.

[0010] Preferably, the positioning frame is U-shaped, and the positioning holes on the surface of the second steel frame are located on both sides of one end of the second steel frame.

[0011] Preferably, the bracket has a reinforcing plate on the side near the placement plate to improve the connection strength between the placement plate and the bracket.

[0012] Preferably, one side of the bracket is provided with several anti-slip blocks to increase the friction on one side of the bracket.

[0013] In summary, the beneficial effects of this utility model are as follows: By using a positioning device, the second steel frame and the first steel frame can be accurately positioned when they come into contact, so that the first steel frame and the second steel frame will not be misaligned during assembly. This avoids instability and error risks when the first bolt is used to assemble and fix the first steel frame and the second steel frame, thereby improving the modular assembly effect of the steel structure.

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium.

[0019] Figures 1 to 6 The illustrated modular prefabricated steel structure includes a first steel frame 1 and a second steel frame 2. A plurality of first bolts 3 are provided on one side of the first steel frame 1, and the first bolts 3 are inserted into the surface of the first steel frame 1 to connect with the second steel frame 2. A positioning device 4 is provided on one side of the first steel frame 1 to position the connection between the first steel frame 1 and the second steel frame 2. During the use of the steel structure, the first steel frame 1 and the second steel frame 2 come into contact, and the positioning device 4 is used to accurately position the connection between the second steel frame 2 and the first steel frame 1. Then, the first bolts 3 are used to connect and fix the contacting first steel frame 1 and the second steel frame 2, thus completing the modular assembly of the steel structure.

[0020] Figures 1 to 6 The positioning device 4 shown includes a mounting plate 41, a second bolt 42, a placement plate 43, a bracket 44, a spring 45, a positioning frame 46, and a positioning hole 47 opened on the second steel frame 2. The mounting plate 41 is disposed on the surface of the first steel frame 1. The second bolt 42 is inserted into one side of the mounting plate 41 to connect with the placement plate 43. The bracket 44 is disposed on one side of the placement plate 43. The two ends of the spring 45 are respectively connected to the bracket 44 and the positioning frame 46. The two ends of the positioning frame 46 penetrate the placement plate 43 and are inserted into the positioning hole 47 on one side of the second steel frame 2 to position the second steel frame 2.

[0021] Figures 1 to 6When using the positioning device 4, the placement plate 43 is inserted into the mounting plate 41 fixed to the surface of the first steel frame 1. Then, the second bolt 42 is rotated to insert the second bolt 42 into the placement plate 43 for threaded fixation with the mounting plate 41. This completes the installation and fixation of the placement plate 43 on one side of the first steel frame 1. When the second steel frame 2 contacts the first steel frame 1, the positioning frame 46 is moved downwards. At this time, both ends of the positioning frame 46 move inside the placement plate 43, causing the spring 45 fixed to the positioning frame 46 and the bracket 44 to compress and deform. Then, the positioning hole 47 on the second steel frame 2 aligns with the positioning frame 46, and the device is released. The positioning bracket 46 is opened, causing the spring 45 to return to its original position. This allows the positioning bracket 46 to move inside the placement plate 43 and reach the positioning hole 47 of the second steel frame 2, thereby engaging and fixing the second steel frame 2. This completes the positioning of the second steel frame 2 and the first steel frame 1. By using the positioning device 4, the second steel frame 2 and the first steel frame 1 can be accurately positioned when they come into contact, preventing the first steel frame 1 and the second steel frame 2 from shifting during assembly. This avoids instability and error risks when the first bolt 3 is used to assemble and fix the first steel frame 1 and the second steel frame 2, thereby improving the modular assembly effect of the steel structure.

[0022] Figures 1 to 6 The telescopic rod 48 shown is sleeved inside the spring 45, and both ends of the telescopic rod 48 are connected to the bracket 44 and the positioning frame 46. By sleeved inside the spring 45 and fixedly connected to the bracket 44 and positioning frame 46 at both ends, the shape of the spring 45 is restricted, preventing the spring 45 from bending and affecting its reset, thus avoiding movement of the positioning frame 46. The positioning frame 46 has inclined grooves 49 at both ends, which are close to the second steel frame 2. The inclined grooves 49 at both ends of the positioning frame 46 allow the second steel frame 2 to press against the inclined grooves 49, bringing the positioning frame 46 closer to the bracket 44 and compressing the spring 45. After the positioning holes 47 on the second steel frame 2 align with the ends of the positioning frame 46, the spring 45 resets, achieving automatic locking and fixing of the positioning frame 46 to the second steel frame 2, thus completing the positioning of the second steel frame 2 and the first steel frame 1.

[0023] Figures 1 to 6The positioning frame 46 shown has several ball bearings 410 in the inclined groove 49 areas at both ends to reduce the contact area between the positioning frame 46 and the second steel frame 2. By having several ball bearings 410 rolling in the inclined groove 49 areas at both ends of the positioning frame 46, the contact area between the positioning frame 46 and the second steel frame 2 is reduced, making it easier for the second steel frame 2 to contact and press against the inclined groove 49 of the positioning frame 46, thereby improving the performance of the positioning frame 46. The positioning frame 46 is U-shaped, and the positioning holes 47 on the surface of the second steel frame 2 are located on both sides of one end of the second steel frame 2. The U-shape of the positioning frame 46 and the location of the positioning holes 47 on both sides of one end of the second steel frame 2 allow the positioning frame 46 to position the two sides of one end of the second steel frame 2, thus making the positioning frame 46 more firmly positioned close to the first steel frame 1, thereby improving the performance of the positioning frame 46.

[0024] Figures 1 to 6 The bracket 44 shown has a reinforcing plate 411 on the side near the placement plate 43 to enhance the connection strength between the placement plate 43 and the bracket 44. By fixing the bracket 44 to the placement plate 43 with the reinforcing plate 411, the connection strength between the placement plate 43 and the bracket 44 is enhanced, preventing deformation at the connection point and thus improving the usability of the bracket 44 and the placement plate 43. Several anti-slip blocks 412 are provided on one side of the bracket 44 to increase friction on that side. By fixing several anti-slip blocks 412 to one side of the bracket 44, the increased friction allows the bracket 44 to be better gripped and moved by the operator, facilitating the movement of the placement plate 43 to the mounting plate 41 for threaded fixing with the second bolt 42.

[0025] Working Principle: When using the steel structure, the first steel frame 1 and the second steel frame 2 come into contact. A positioning device 4 is used to precisely position the connection between the second steel frame 2 and the first steel frame 1. Then, the first bolt 3 is used to connect and fix the contacting first steel frame 1 and the second steel frame 2, completing the modular assembly of the steel structure. When using the positioning device 4, one side of the placement plate 43 is inserted into the mounting plate 41 fixed to the surface of the first steel frame 1. Then, the second bolt 42 is rotated, causing it to be inserted into the placement plate 43 for threaded fixation with the mounting plate 41. This completes the installation and fixation of the placement plate 43 on one side of the first steel frame 1. When the second steel frame 2 comes into contact with the first steel frame 1, the positioning frame 46 is moved downwards. At this time, both ends of the positioning frame 46 move inside the placement plate 43, causing the spring 45, which is fixed to the positioning frame 46 and the bracket 44, to compress and deform. Then, the positioning hole 47 on the second steel frame 2 aligns with the positioning frame 46, and the device is released. The positioning frame 46 resets the spring 45, causing the positioning frame 46 to move inside the placement plate 43 and reach the positioning hole 47 of the second steel frame 2 to engage and fix the second steel frame 2, thus completing the positioning of the second steel frame 2 and the first steel frame 1. By using the positioning device 4, the second steel frame 2 and the first steel frame 1 can be accurately positioned when they come into contact, so that the first steel frame 1 and the second steel frame 2 will not be offset during the assembly process. This avoids instability and error risks when the first bolt 3 is used to assemble and fix the first steel frame 1 and the second steel frame 2, thereby improving the modular assembly effect of the steel structure.
