Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, specifically to a transition structure for connecting tie rods and C-shaped purlins. Background Technology

[0002] In the field of steel structure construction, the connection between tie rods and purlins is a crucial element in ensuring structural stability. As a key structural component, tie rods primarily enhance the lateral stability of purlins. Purlins in steel structure systems typically bear vertical loads and horizontal loads such as wind loads. When the span is large, they are prone to lateral bending and torsional deformation. Tie rods, by connecting to the purlins, constrain their lateral displacement and torsion, ensuring that the purlins remain stable under load.

[0003] For C-shaped purlins, there are three main traditional ways to connect tie rods to C-shaped purlins: First, such as... Figure 1 As shown, a direct bolt connection is used, with the tie rod passing through the opening in the web of the C-shaped purlin and the end tightened with a nut for fixation. However, during long-term use, structural vibration and temperature changes can easily cause the bolts to loosen, leading to connection failure. Furthermore, this method affects the subsequent installation and opening of doors and windows, hindering the construction process. Secondly, as... Figure 2 As shown, a bent C-shaped connector is used for connection. This method has high requirements for the position of the opening in the web of the C-shaped purlin. If the edge distance of the opening is too close, the C-shaped connector is prone to collision with the flange of the C-shaped purlin, and its stress mode is prone to deformation, which is not conducive to the transmission of vertical and horizontal forces. Thirdly, as Figure 3 As shown, short purlins are welded together, but this method is not conducive to large-scale production in the processing plant. It will lead to an increase in the number of C-type purlins, complicated packaging and shipping, and increased transportation costs. If implemented on-site, the workload will increase significantly, and the on-site welding quality will be difficult to guarantee.

[0004] It is evident that traditional connection methods in C-type purlin applications suffer from problems such as loosening, deformation, and complex construction, necessitating optimized design to improve connection reliability and construction efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a transition structure between tie rods and C-shaped purlins to solve the above-mentioned problems.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A transition structure for connecting a tie rod and a C-shaped purlin includes a column and a fastener. A first connecting hole and a second connecting hole are provided in the column. The first connecting hole extends from one end of the column into the column, and the second connecting hole extends from the other end of the column into the column. The first connecting hole is connected to the connecting end of the tie rod. The fastener is provided on the C-shaped purlin and can be connected to the second connecting hole.

[0008] As a further improvement of this utility model, the first connecting hole is a threaded hole, and a thread that mates with the first connecting hole is provided on the connecting end of the pull bar. The column is threadedly connected to the pull bar through the first connecting hole.

[0009] As a further improvement of this utility model, the second connecting hole is a threaded hole, and an mounting hole is provided on the web of the C-shaped purlin. The fastener is a bolt, and the bolt passes through the mounting hole and is threadedly connected to the second connecting hole.

[0010] As a further improvement to this utility model, the bolt is a flat-head bolt.

[0011] As a further improvement of this utility model, a limiting part is provided in the first connecting hole, and the limiting part is used to limit the depth of the connecting end of the pull bar in the first connecting hole.

[0012] As a further improvement of this utility model, the first connecting hole and the second connecting hole are coaxially arranged.

[0013] As a further improvement of this utility model, the threads of the first connecting hole and the threads of the second connecting hole have opposite directions.

[0014] As a further improvement of this utility model, at least two third connecting holes are provided on the side wall of the column. At least one of the third connecting holes is connected to the first connecting hole, and the remaining third connecting holes are connected to the second connecting holes. A locking member is provided in the third connecting hole. The locking member connected to the first connecting hole is used to lock the pull bar, and the locking member connected to the second connecting hole is used to lock the bolt.

[0015] As a further improvement of this utility model, the third connecting hole is a threaded hole, and the locking member is a pin that cooperates with the third connecting hole.

[0016] As a further improvement of this utility model, chamfers are provided on both ends of the column.

[0017] The beneficial effects of this utility model are as follows:

[0018] The above structure simplifies the installation process, significantly shortens the construction cycle, reduces the length of the tie rod, lowers construction costs, improves the reliability of the connection, avoids structural safety hazards caused by loose connections, and makes the installation and disassembly of the transition structure easy, improving the maintainability of the structure.

[0026] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0027] If the description of this utility model involves directions (e.g., up, down, left, right, front, back, outside, inside, etc.), then the directions involved need to be defined. For example, "To clearly express the position and direction described in this utility model, the operator of the instrument is used as a reference, the end closer to the operator is the proximal end, and the end farther from the operator is the distal end." Or, the paper can be used as a reference. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, then this definition is not required.

[0028] like Figures 4-6As shown, a connecting structure for connecting a tie rod 1 and a C-shaped purlin 2 includes a column 3 and a fastener. A first connecting hole 4 and a second connecting hole 5 are provided in the column 3. The first connecting hole 4 extends from one end of the column 3 into the column 3, and the second connecting hole 5 extends from the other end of the column 3 into the column 3. The first connecting hole 4 is connected to the connecting end of the tie rod 1. The fastener is provided on the C-shaped purlin 2 and can be connected to the second connecting hole 5, thereby connecting the C-shaped purlin 2 and the column 3 together.

[0029] As an embodiment of this utility model, in order to improve the connection strength and connection convenience, the first connection hole 4 is set as a threaded hole, and a thread that matches the first connection hole 4 is provided on the connection end of the pull bar 1. The column 3 is threadedly connected to the pull bar 1 through the first connection hole 4. The threaded connection can provide sufficient tensile strength and shear strength.

[0030] The second connecting hole 5 is a threaded hole. An mounting hole is provided on the web of the C-shaped purlin 2. The fastener is a bolt 6, which passes through the mounting hole and engages with the thread of the second connecting hole 5. The bolt 6 is threadedly connected to the second connecting hole 5, thus connecting the column 3 to the web of the C-shaped purlin 2. This bolt connection is simple to operate and allows for fast construction. Specifically, the bolt 6 is a flat-head bolt 6. The flat head of the flat-head bolt 6 allows for better contact with the surface of the web of the C-shaped purlin 2, reducing stress concentration.

[0031] In one embodiment of this utility model, a limiting part 401 is provided in the first connecting hole 4. The limiting part 401 is used to limit the depth of the connecting end of the pull bar 1 in the first connecting hole 4, so that the connecting end of the pull bar 1 can be directly screwed to the column 3. When the connecting end of the pull bar 1 abuts against the limiting part 401 and cannot move, the positioning of the pull bar 1 can be achieved. Specifically, the first connecting hole 4 and the second connecting hole 5 can be set to not be connected. Then the first connecting hole 4 has a bottom, which is the limiting part 401. At the same time, the connecting end of the pull bar 1 set in the first connecting hole 4 and the bolt 6 set in the second connecting hole 5 do not contact each other and do not affect each other.

[0032] As one embodiment of this utility model, the first connecting hole 4 and the second connecting hole 5 are coaxially arranged, which improves the fitting accuracy and connection convenience during connection and facilitates positioning.

[0033] As one embodiment of this utility model, the threads of the first connecting hole 4 and the second connecting hole 5 have opposite directions of rotation, which improves the convenience of installation and operation, prevents the connectors from loosening under vibration or external force, and improves the reliability of the connection.

[0034] In one embodiment of this utility model, at least two third connecting holes 7 are provided on the side wall of the column 3. At least one of the third connecting holes 7 communicates with the first connecting hole 4, and the remaining third connecting holes 7 communicate with the second connecting holes 5. A locking member is provided in each of the third connecting holes 7. The locking member communicating with the first connecting hole 4 is used to lock the pull bar 1, and the locking member communicating with the second connecting hole 5 is used to lock the bolt 6. Specifically, there are two third connecting holes 7. One third connecting hole 7 communicates with the first connecting hole 4, and the other third connecting hole 7 communicates with the second connecting hole 5. A locking member is provided in each of the third connecting holes 7. Specifically, the third connecting hole 7 is a threaded hole, and the locking member is a pin 8 that cooperates with the third connecting hole 7. The two pins 8 limit the loosening of the pull bar 1 and the flat-head bolt 6 caused by vibration, temperature changes, and other factors by pushing and locking, thereby improving the reliability and stability of the connection.

[0035] As an embodiment of this utility model, chamfers are provided on both ends of the column 3 to avoid the problem of burrs or other processing residues that may exist on the edge of the end face of the column 3 during processing. This allows the end face of the column 3 to perfectly fit the web of the C-shaped purlin 2, ensuring the stability of the connection and the straightness of the installation of the tie rod 1. This makes the tie rod 1 and the C-shaped purlin 2 form a complete force-bearing system, achieving a coordinated unity of functionality, economy, and safety.

[0036] like Figure 4 As shown, during installation, first screw the end of the tie rod 1 to the first connecting hole 4. After screwing it in place, pass the bolt 6 through the mounting hole on the web of the C-shaped purlin 2 and screw the bolt 6 to the second connecting hole 5. After screwing it in place, screw the pin 8 into the third connecting hole 7 to push the tie rod 1 and the bolt 6. After screwing it in place, the installation is complete.

[0037] The adapter structure provided by this utility model adopts a threaded connection between the tie rod 1 and the C-shaped purlin 2, which simplifies the installation steps, significantly shortens the construction cycle, reduces the length of the tie rod 1, reduces steel consumption, and eliminates the use of installation nuts, improving the project's economy and effectively reducing construction costs. The threaded connection combined with the pin 8 push-locking design greatly improves the reliability of the connection and avoids structural safety hazards caused by loose connections. The adapter structure is easy to install and disassemble, facilitating later maintenance, modification, or replacement of components in the building structure, thus improving the maintainability of the structure. It perfectly solves the problem of inconvenience in subsequent door and window installation and opening caused by the traditional method of the tie rod 1 passing through the web opening of the C-shaped purlin 2 and being fixed with nuts, providing greater convenience for construction and subsequent use.

[0038] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0039] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementation methods or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
