Description

Technical Field

[0001] This utility model relates to the field of assembled steel connection, and more specifically, it relates to a quick positioning connection structure for assembled steel structures. Background Technology

[0002] With the construction industry's continuous pursuit of efficiency, environmental protection, and industrialization, prefabricated steel structures have become an important development direction for modern architecture due to their advantages such as fast construction speed and recyclability.

[0003] When using existing devices, the connection method relies on a complex measurement and calibration process, which results in low positioning efficiency and is prone to deviations, often leading to rework and seriously affecting the construction progress. At the same time, some connection structures have insufficient vibration resistance and stability, making it difficult to meet the safety requirements of building structures.

[0004] Therefore, it is necessary to redesign a prefabricated steel structure quick positioning and connection structure to address the above-mentioned problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a quick positioning connection structure for prefabricated steel structures.

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

[0007] A quick-positioning connection structure for prefabricated steel structures includes two prefabricated steel sections arranged symmetrically. Each prefabricated steel section has a connecting hole and two guide holes symmetrically formed on each section, with the connecting hole located in the middle of the two guide holes. A bidirectional screw is provided between the two connecting holes. A positioning component is slidably connected to the outer wall of the bidirectional screw, and the output end of the positioning component passes through the corresponding guide holes. A limit block is fixedly installed at the bottom end of the bidirectional screw, and a first nut and a second nut are symmetrically threaded onto the bidirectional screw.

[0008] In a preferred embodiment, the positioning component includes a fixing plate, which is slidably sleeved on the outer wall of the bidirectional screw. Two guide rods are symmetrically fixedly installed on the upper end face of the fixing plate, and the two guide rods pass through corresponding guide holes and extend outward.

[0009] In a preferred embodiment, a first sealing gasket and a second sealing gasket are respectively fitted on the outer wall of the bidirectional screw, with the first sealing gasket located at the bottom end of the first nut and the second sealing gasket located at the top end of the second nut.

[0010] In a preferred embodiment, the size of each of the connecting holes is adapted to the size of the bidirectional screw.

[0011] In a preferred embodiment, the dimensions of each guide rod are adapted to the dimensions of the guide hole.

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

[0013] 1. This utility model, by setting up positioning components, guide holes, bidirectional screws and other devices, achieves rapid lateral positioning of two assembly steel pieces through the precise cooperation of the guide holes and guide rods, eliminating the need for complex measurement and calibration steps, and greatly shortening the assembly time. At the same time, the cooperation between the positioning components and the bidirectional screws ensures that the assembly steel pieces are accurately aligned during installation, effectively reducing rework problems caused by positioning deviations.

[0014] 2. This utility model uses a first nut, a second nut, a first sealing gasket, and a second sealing gasket to set up a device. The bidirectional screw, together with the first nut and the second nut, applies axial clamping force. Combined with the first sealing gasket and the second sealing gasket, it increases friction and disperses pressure, thereby achieving three-dimensional fastening of the assembled steel and giving the connection structure good stability and vibration resistance.

[0015] In summary, this utility model is simple to operate. The cooperation between the guide hole and the guide rod enables rapid lateral positioning of the assembled steel, simplifies the measurement and calibration process, shortens the assembly time, reduces rework, and the bidirectional screw and double nuts apply axial clamping force. The sealing gasket increases friction and disperses pressure to achieve three-dimensional fastening, ensuring the stability and vibration resistance of the connection structure.

[0021] 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.

[0022] Reference Figure 1-4 A quick-positioning connection structure for prefabricated steel structures includes two prefabricated steel bars 1, which are symmetrically arranged. Each prefabricated steel bar 1 has a connecting hole 11 and two guide holes 3 symmetrically arranged on each prefabricated steel bar 1. The connecting hole 11 is located in the middle of the two guide holes 3. A bidirectional screw 2 is provided between the two connecting holes 11. The size of each connecting hole 11 is adapted to the size of the bidirectional screw 2. A positioning component is slidably connected to the outer wall of the bidirectional screw 2, and the output end of the positioning component passes through the corresponding guide hole 3. A limit block 6 is fixedly installed at the bottom end of the bidirectional screw 2. A first nut 7 and a second nut 8 are symmetrically threaded on the bidirectional screw 2. Tightening these two nuts will generate an axial clamping force through the threaded engagement of the nuts and the screw, which will tightly fix the two prefabricated steel bars 1 together.

[0023] The positioning assembly includes a fixing plate 5, which is slidably sleeved on the outer wall of the bidirectional screw 2. Two guide rods 4 are symmetrically fixedly installed on the upper end face of the fixing plate 5, and the two guide rods 4 pass through the corresponding guide holes 3 and extend outward. The size of each guide rod 4 is adapted to the size of the guide hole 3. The tight fit between the guide rod 4 and the guide hole 3 restricts the horizontal displacement of the assembly steel 1, ensures accurate connection position, avoids the decrease in connection strength due to misalignment, simplifies the assembly process, and improves construction efficiency.

[0024] The outer wall of the bidirectional screw 2 is respectively fitted with a first sealing gasket 9 and a second sealing gasket 10. The first sealing gasket 9 is located at the bottom end of the first nut 7, and the second sealing gasket 10 is located at the top end of the second nut 8. The gasket can increase the contact area between the nut and the surface of the assembly steel 1, disperse the pressure generated when the nut is tightened, and prevent the surface of the assembly steel 1 from being damaged due to excessive local stress.

[0025] When using this utility model, during assembly, first align the two guide holes 3 on one piece of assembly steel 1 with the two guide rods 4 in the positioning assembly, and then place the assembly steel 1 on the fixing plate 5. At this time, operate the other piece of assembly steel 1 in the same way, aligning its guide holes 3 with the guide rods 4. Through the precise cooperation between the guide holes 3 and the guide rods 4, the two pieces of assembly steel 1 can be quickly positioned laterally, ensuring that their positions correspond accurately.

[0026] The first nut 7 and the second nut 8 are symmetrically threaded onto the bidirectional screw 2. The first sealing gasket 9 and the second sealing gasket 10, fitted onto the outer wall of the screw, are located at the contact points between the nuts and the assembly steel 1. After the guide rod 4 completes its positioning, the first nut 7 and the second nut 8 are tightened. Utilizing the thread transmission characteristics of the nuts and the screw, an axial clamping force is applied to the two assembly steel 1s. The sealing gaskets increase contact friction, disperse pressure, and prevent the nuts from loosening while protecting the surface of the assembly steel 1, ensuring that the assembly steel 1 is firmly fixed axially. Combined with the lateral positioning achieved by the guide rod 4, a three-dimensional fastening effect is achieved, ensuring the stability of the connection structure.

[0027] When disassembly is required, rotate the first nut 7 and the second nut 8 in the opposite direction to release the axial clamping force on the assembly steel 1. Once the clamping constraint is released, the two assembly steel 1s can be easily separated. Thanks to its threaded connection and guide positioning design, it enables rapid disassembly and reuse, making it suitable for various steel structure scenarios involving frequent assembly and disassembly.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
