Technical Field

[0001] This application relates to the technical field of cold-formed thin-walled steel, and in particular to a reinforcement structure for cold-formed thin-walled C-shaped steel purlins. Background Technology

[0002] Cold-formed thin-walled profiles, as a type of high-efficiency and energy-saving thin-walled steel plate, have superior material properties compared with hot-rolled and welded steel profiles, such as uniform wall thickness, diverse self-folding cross-sectional shapes, large cross-sectional radius of gyration and moment of inertia, as well as flexible and versatile riveting and bolting assembly performance. They are widely used in prefabricated steel structures and modular housing panels.

[0003] Cold-formed thin-walled steel sections are prone to instability under stress because of their thin walls and mostly non-closed cross sections. Utility Model Content

[0004] To improve stability, this application provides a reinforcement structure for cold-formed thin-walled C-shaped steel purlins.

[0005] This application provides a reinforcement structure for cold-formed thin-walled C-shaped steel purlins, employing the following technical solution:

[0006] A reinforcement structure for a cold-formed thin-walled C-shaped steel purlin includes a C-shaped purlin and a first reinforcement mechanism. The first reinforcement mechanism includes a Z-shaped purlin and a first connecting component. The Z-shaped purlin is disposed at the bottom of the C-shaped purlin through the first connecting component.

[0007] By adopting the above technical solution, the Z-shaped purlin is connected to the C-shaped purlin through the first connecting component to enlarge the purlin cross section and strengthen it, thereby increasing its strength and stiffness and improving its stability.

[0008] Optionally, the first connecting component includes a connecting adhesive, one side of which abuts against the C-shaped purlin and the other side against the Z-shaped purlin.

[0009] By adopting the above technical solution, the connecting adhesive is applied to the joint between the Z-shaped purlin and the C-shaped purlin, and the Z-shaped purlin and the C-shaped purlin are connected together by the adhesive function of the connecting adhesive.

[0010] Optionally, the first connecting assembly includes a first blind rivet, the Z-shaped purlin has a first through hole, the C-shaped purlin has a second through hole, one end of the first blind rivet passes through the first through hole and the second through hole, one end of the first blind rivet abuts against the Z-shaped purlin and the other end abuts against the C-shaped purlin.

[0011] By adopting the above technical solution, the Z-shaped purlin and the C-shaped purlin are first brought into contact, then one end of the first pop rivet passes through the first through hole and the second through hole, and then one end of the first rivet is pressed against the Z-shaped purlin and the other end is pressed against the C-shaped purlin, so that the Z-shaped purlin and the C-shaped purlin are firmly connected together; the first connecting component is simple in structure and easy to operate.

[0012] Optionally, a second reinforcement mechanism is also included, which includes a reinforcement block and a second connecting component. One end of the reinforcement block is connected to the Z-shaped purlin via the second connecting component, and the other end of the reinforcement block is connected to the C-shaped purlin via the second connecting component.

[0013] By adopting the above technical solution, before connecting the Z-shaped purlin and the C-shaped purlin with the first connecting component, one end of the reinforcing block abuts against the Z-shaped purlin and the other end abuts against the C-shaped purlin. Then, the second connecting component is used to connect the reinforcing block and the Z-shaped purlin, and the reinforcing block and the C-shaped purlin. The second reinforcing mechanism can improve the stability of the connection between the Z-shaped purlin and the C-shaped purlin.

[0014] Optionally, the Z-shaped purlin has a third through hole, the C-shaped purlin has a fourth through hole, and one end of the reinforcing block passes through the third and fourth through holes; the second connecting assembly includes a second blind rivet, the reinforcing block has a fifth through hole, the Z-shaped and C-shaped purlins have a sixth through hole, one end of the second blind rivet passes through the fifth and sixth through holes, one end of the second blind rivet abuts against the Z-shaped or C-shaped purlin and the other end abuts against the reinforcing block.

[0015] By adopting the above technical solution, one end of the reinforcing block is first passed through the third and fourth through holes, so that one end of the reinforcing block abuts against the Z-shaped purlin and the other end abuts against the C-shaped purlin, and the axis of the fifth through hole coincides with the axis of the sixth through hole; then, the second pop rivet is passed through the fifth and sixth through holes, one end of the second pop rivet abuts against the Z-shaped purlin or C-shaped purlin and the other end abuts against the reinforcing block, so that the Z-shaped purlin and C-shaped purlin are firmly connected together by the reinforcing block, thereby improving the stability when the Z-shaped purlin and C-shaped purlin are connected together.

[0016] Optionally, the reinforcing block is provided with a positioning mechanism, which includes a positioning block and a locking block. The reinforcing block has a locking groove, and the locking block engages with the locking groove. The positioning block is disposed on the locking block and can abut against the Z-shaped purlin.

[0017] By adopting the above technical solution, the card block is first engaged with the card slot, so that the positioning block is connected to the reinforcing block. Then, when one end of the reinforcing block passes through the third and fourth through holes, the positioning block abuts against the Z-shaped or C-shaped purlin, so that the axis of the fifth through hole and the axis of the sixth through hole coincide, which facilitates the subsequent installation of the second pull rivet. Therefore, the positioning mechanism has a positioning function, reduces the adjustment time of the reinforcing block, and thus improves efficiency.

[0018] Optionally, the card block is provided with a stabilizing mechanism, which includes a stabilizing block and an adjusting component. The stabilizing block is slidably disposed on the card block, and a stabilizing groove is formed on the side wall of the card slot to engage with the stabilizing block.

[0020] Optionally, the adjustment assembly includes a spring, an adjustment rod, and an adjustment block. The locking block has a cavity, a seventh through hole communicating with the cavity, and an eighth through hole communicating with the cavity.

The positioning block has a ninth through hole communicating with the eighth through hole. The adjustment block is slidably disposed in the ninth through hole. One end of the adjustment rod is connected to the adjustment block and the other end is connected to the stabilizing block.

[0021] By adopting the above technical solution, when it is necessary to separate the card block from the card slot, the adjusting block is pulled, the adjusting block drives the adjusting rod to move, the adjusting rod drives the stabilizing block to move, and the stabilizing block will stabilize the card slot to separate. At this time, the spring will deform; then the operator pulls the positioning block to separate the card block from the card slot; the setting of the adjustment component has a simple structure and is easy to operate.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0032] The first reinforcing mechanism 2 includes a Z-shaped purlin 21 with a cross-sectional specification of Z100x70x20x2. The Z-shaped purlin 21 is located at the bottom of the C-shaped purlin 1 and abuts against the C-shaped purlin 1. After the Z-shaped purlin 21 is connected to the C-shaped purlin 1, the cross-section of the purlin will be expanded to C200x70x20x2 + Z100x70x20x2.

[0033] A first connecting component is provided on the C-shaped purlin 1 to connect with the Z-shaped purlin 21. The first connecting component includes a connecting adhesive, which in this embodiment is a steel-adhesive adhesive. The ends of the C-shaped purlin 1 and the Z-shaped purlin 21 that are close to each other are coated with steel-adhesive adhesive. Then, the ends of the C-shaped purlin 1 and the Z-shaped purlin 21 coated with steel-adhesive adhesive are brought together. A second through hole is opened on the end of the C-shaped purlin 1 near the Z-shaped purlin 21, and a first through hole is opened on the end of the Z-shaped purlin 21 near the C-shaped purlin 1. A first blind rivet 22 is provided on the Z-shaped purlin 21. One end of the first blind rivet 22 passes through the first through hole on the Z-shaped purlin 21 and the second through hole on the C-shaped purlin 1. Then, one end of the first blind rivet 22 is pressed against the C-shaped purlin 1 and the other end is pressed against the Z-shaped purlin 21. The method of fixing two plates or blocks with pop rivets 321 is existing technology and will not be described in detail in this embodiment.

[0034] refer to Figure 1 and Figure 2 A third through hole is provided on the end of the Z-shaped purlin 21 near the end of the C-shaped purlin 1, and a fourth through hole is provided on the end of the C-shaped purlin 1 near the end of the Z-shaped purlin 21. A second reinforcing mechanism 3 is provided on the Z-shaped purlin 21. The second reinforcing mechanism 3 includes a rectangular reinforcing block 31. The cross-section of the reinforcing block 31, the cross-section of the third through hole, and the cross-section of the fourth through hole are the same. One end of the reinforcing block 31 passes through the third through hole on the Z-shaped purlin 21 and the fourth through hole on the C-shaped purlin 1, so that one end of the reinforcing block 31 abuts against the C-shaped purlin 1 and the other end abuts against the Z-shaped purlin 21. A fifth through hole is provided on the reinforcing block 31, and a sixth through hole is provided on both the C-shaped purlin 1 and the Z-shaped purlin 21. A second connecting component 32 is provided on the reinforcing block 31. The second connecting component 32 includes a second pull rivet 321. One end of the second pull rivet 321 passes through the fifth through hole and the sixth through hole. One end of the second pull rivet 321 abuts against the reinforcing block 31 and the other end abuts against the C-shaped purlin 1 or the Z-shaped purlin 21.

[0035] refer to Figure 1 and Figure 2 The reinforcing block 31 has a slot and a positioning mechanism 4. The positioning mechanism 4 includes a card block 42 that engages with the slot. The positioning block 42 is fixedly connected to the positioning block 41. When the positioning block 41 abuts against the Z-shaped purlin 21, the axis of the fifth through hole and the axis of the sixth through hole coincide.

[0036] refer to Figure 2 The card block 42 has a cavity 421, and the positioning block 41 has a seventh through hole and an eighth through hole 422 communicating with the cavity 421. The axis of the seventh through hole and the axis of the eighth through hole 422 are perpendicular, and the axis of the seventh through hole is perpendicular to the positioning block 41. The positioning block 41 has a ninth through hole communicating with the eighth through hole 422 on the card block 42.

[0037] A stabilizing mechanism 5 is provided on the locking block 42. The stabilizing mechanism 5 includes a stabilizing block 51 that is slidably connected in the seventh through hole. A stabilizing groove is provided on the reinforcing block 31 that communicates with the locking groove and engages with the stabilizing block 51. One end of the stabilizing block 51 is located in the cavity 421. An adjusting component 52 is provided on the positioning block 41. The adjusting component 52 includes an adjusting block 522 that is slidably connected in the ninth through hole. One end of the adjusting block 522 is located outside the positioning block 41, and the other end passes through the ninth through hole and the eighth through hole 422 and is located in the cavity 421. An adjusting rod 521 is hinged to the adjusting block 522 located in the cavity 421. The end of the adjusting rod 521 away from the adjusting block 522 is hinged to the stabilizing block 51. A spring is sleeved on the stabilizing block 51. One end of the spring is connected to the stabilizing block 51, and the other end is connected to the locking block 42. When the spring is in the normal state, the stabilizing block 51 can engage with the stabilizing groove. A red mark and a green mark are provided on the adjustment block 522 located outside the positioning block 41. When both the red mark and the green mark are located inside the ninth through hole, it indicates that the spring is in normal condition. When both the red mark and the green mark are located outside the positioning block 41, it indicates that the end of the stabilizing block 51 away from the cavity 421 is located inside the seventh through hole.

[0038] The implementation principle of the reinforcement structure in Embodiment 1 of this application is as follows: firstly, steel-adhesive is applied to the ends of the C-shaped purlin 1 and the Z-shaped purlin 21 that are close to each other.

[0039] Then pull the adjusting block 522 so that the red and green marks are both outside the positioning block 41, meaning the operator can see the red and green marks. At this time, the spring is in a deformed state. Next, engage the locking block 42 with the locking groove on the reinforcing block 31. When the positioning block 41 abuts against the reinforcing block 31, release the adjusting block 522. The force of the spring restoring its elastic deformation drives the stabilizing block 51 to move towards the stabilizing groove and engage with it. When the stabilizing block 51 moves, it will drive the adjusting rod 521 to move. The adjusting rod 521 drives the adjusting block 522 to move, so that the red and green marks on the adjusting block 522 are both inside the ninth through hole.

[0040] Then, one end of the reinforcing block 31 is passed through the third through hole on the Z-shaped purlin 21 and the fourth through hole on the C-shaped purlin 1 in sequence, and the positions of the C-shaped purlin 1 and the Z-shaped purlin 21 are adjusted. When the positioning block 41 abuts against the Z-shaped purlin and the C-shaped purlin 1 abuts against the Z-shaped purlin 21, the fifth through hole on one end of the reinforcing block 31 coincides with the sixth through hole on the C-shaped purlin 1, and the fifth through hole on the other end of the reinforcing block 31 coincides with the sixth through hole on the Z-shaped purlin 21; and the axis of the second through hole on the C-shaped purlin 1 coincides with the axis of the first through hole on the Z-shaped purlin 21. Next, one end of the second pop rivet 321 is passed through the reinforcing block 31, the fifth through hole, and the sixth through hole on the C-shaped purlin 1, and then one end of the second pop rivet 321 is pressed against the C-shaped purlin 1 and the other end is pressed against the reinforcing block 31. Then, pass one end of the second pop rivet 321 through the reinforcing block 31, the fifth through hole, and the sixth through hole on the Z-shaped purlin 21. Then, press one end of the second pop rivet 321 against the Z-shaped purlin 21 and the other end against the reinforcing block 31. Then pull the adjusting block 522 to make the stabilizing block 51 no longer engage with the stabilizing groove and to separate the locking block 42 from the locking groove.

[0041] Finally, one end of the first pull rivet 22 passes through the first through hole and the second through hole, and then one end of the first suction rivet abuts against the C-shaped purlin 1 and the other end against the Z-shaped purlin 21. Example

[0042] refer to Figure 3 The difference from Embodiment 1 is that the adjustment component 52 includes a rotating shaft 523, which is rotatably disposed in the ninth through hole. One end of the rotating shaft 523 is located outside the positioning block 41 and the other end is located inside the cavity 421. A drive gear 524 is keyed to the rotating shaft 523 located in the cavity 421. A rack 525 that meshes with the drive gear 524 is fixedly connected to the stabilizing block 51 located in the cavity 421.

[0043] Rotating the shaft 523 causes the drive gear 524 to rotate, which in turn drives the rack 525 to move. The rack 525 then drives the stabilizing block 51 to move, causing the stabilizing block 51 to engage with or separate from the stabilizing groove.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
