Description

Technical Field

[0001] This utility model relates to the field of purlin reinforcement technology, specifically a purlin reinforcement structure. Background Technology

[0002] Purlins, also known as purlins or rafters, are horizontal roof beams perpendicular to the roof trusses or rafters, used to support the rafters or roofing materials. Purlins are transversely bending members (usually bi-directional bending) and are generally designed as single-span simply supported purlins. Commonly used purlins include solid-web and light steel truss types.

[0003] Since the purlins are subjected to stress independently, they are often fixed by welding when splicing them. However, the load-bearing capacity and toughness of the joints of the entire purlin after fixing are poor. Therefore, this does not meet the current requirements. To address this, we propose a purlin reinforcement structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a purlin reinforcement structure. To solve the above-mentioned technical problem, the technical solution of this utility model is as follows:

[0005] A purlin reinforcement structure includes a first purlin and a second purlin. A slot is formed on the same side of both the first and second purlins. A locking block adapted to the slot is fixedly connected to the other side of both the first and second purlins, and the locking block on one side of the first purlin engages with the slot on one side of the second purlin. A reinforcement block is provided between the internal connections of the first and second purlins. Symmetrical driving cavities are formed on the upper and lower sides of both sides of the reinforcement block. A limiting block is movably connected to the interior of each of the upper and lower driving cavities, penetrating the driving cavity and extending to the outside of the reinforcement block. The limiting block is connected to the inner wall of the corresponding first and second purlins.

[0006] Preferably, a groove is provided between the upper and lower driving cavities, and a rotating rod is rotatably connected to the inside of the groove via a rotating shaft. A driving block is fixedly connected to the outer surface of the rotating rod, and the two ends of the driving block are arranged in an extended, protruding arc shape.

[0007] Preferably, a sliding plate is slidably connected inside both the upper and lower driving cavities, and a connecting rod is fixedly connected to the side of the upper and lower sliding plates that are close to each other. A first spring is fixedly connected between one side of the sliding plate and one side of the inner wall of the driving cavity, and the first spring is wound around the outer surface of the connecting rod. The end of the connecting rod away from the sliding plate extends movably through the groove and slides in contact with the outer surface of the driving block.

[0008] Preferably, the limiting block is fixedly connected to one side of the upper and lower sliding plates that are far apart from each other. Symmetrical first limiting grooves are provided on the upper and lower sides of both the inner sides of the first purlin and the second purlin. The limiting block extends through to one end of the outer side of the reinforcing block and is inserted into the corresponding first limiting groove.

[0009] Preferably, on the side of the two grooves that are far apart from each other, and inside the reinforcing block, there are symmetrical movable cavities, and each of the two movable cavities is movably connected to a limiting rod that extends through to the outside of the movable cavity.

[0010] Preferably, a limiting plate is fixedly connected to the outer surface of one end of the limiting rod inside the movable cavity, and a second spring is fixedly connected between one side of the limiting plate and the inner wall of the movable cavity, and the second spring is wound around the outer surface of the limiting rod.

[0011] Preferably, one end of the limiting rod extends through the outside of the movable cavity into the inside of the groove, and a second limiting groove is provided on one side of the outer surface of the rotating rod, and the end of the limiting rod extending through the groove is inserted into the corresponding second limiting groove.

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

[0013] This invention achieves initial docking of the first and second purlins by engaging a locking block on one side of the first purlin with a locking groove on the other side. Then, a reinforcing block is slidably engaged between the first and second purlins. Next, rotating rods inside the grooves on both sides cause the driving block to rotate. When the extended arc surfaces at both ends of the driving block rotate to a vertical position, the connecting rods at the upper and lower ends slide against the outer surface of the driving block. Through the pressure of the protruding ends of the driving block, the connecting rods and sliding plates move along the interior of the driving cavity, compressing the first spring. This compresses the first spring, causing the limiting block to extend through and into the outer side of the reinforcing block, where it engages with the first limiting groove. This fixes the reinforcing block between the first and second purlins, providing support and reinforcement for the connection. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figure 1 As shown, one embodiment of this utility model provides a purlin reinforcement structure, including a first purlin 1 and a second purlin 2. A slot 101 is provided on the same side of both the first purlin 1 and the second purlin 2. A locking block 3 adapted to the slot 101 is fixedly connected to the other side of both the first purlin 1 and the second purlin 2. The locking block 3 on one side of the first purlin 1 engages with the slot 101 on one side of the second purlin 2. A reinforcement block 4 is provided between the internal connections of the first purlin 1 and the second purlin 2. Symmetrical driving cavities 402 are provided on the upper and lower sides of both sides of the reinforcement block 4. A limiting block 10 is movably connected to the interior of both upper and lower driving cavities 402, penetrating the driving cavity 402 and extending to the outside of the reinforcement block 4. The limiting block 10 is connected to the inner wall of the corresponding first purlin 1 and second purlin 2.

[0021] As a preferred technical solution in this embodiment, such as Figure 2 As shown, a groove 401 is provided between the upper and lower driving cavities 402. A rotating rod 5 is rotatably connected to the inside of the groove 401 via a rotating shaft. A driving block 6 is fixedly connected to the outer surface of the rotating rod 5. The two ends of the driving block 6 are arranged in an extended, protruding arc shape. A sliding plate 7 is slidably connected to the inside of the upper and lower driving cavities 402. A connecting rod 8 is fixedly connected to the side of the upper and lower sliding plates 7 that are close to each other. A first spring 9 is fixedly connected between one side of the sliding plate 7 and one side of the inner wall of the driving cavity 402. The first spring 9 is wrapped around the outer surface of the connecting rod 8. The end of the connecting rod 8 away from the sliding plate 7 extends movably through the groove 401 and slides in contact with the outer surface of the driving block 6.

[0022] In this embodiment, the first purlin 1 and the second purlin 2 are initially connected by engaging the locking block 3 on one side of the first purlin 1 with the locking groove 101 on one side of the second purlin 2. Then, the reinforcing block 4 is slidably engaged between the connection between the first purlin 1 and the second purlin 2. Next, the rotating rod 5 inside the grooves 401 on both sides is rotated, so that the rotating rod 5 drives the driving block 6 to rotate. When the extended arc surfaces at both ends of the driving block 6 rotate to a vertical state, the connecting rods 8 at the upper and lower ends slide into contact with the outer surface of the driving block 6.

[0023] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 3 As shown, the limiting block 10 is fixedly connected to the side of the upper and lower sliding plates 7 that are far apart from each other. The upper and lower sides of the inner sides of the first purlin 1 and the second purlin 2 are provided with symmetrical first limiting grooves 11. The end of the limiting block 10 extending through to the outside of the reinforcing block 4 is inserted into the corresponding first limiting groove 11. The connecting rods 8 at the upper and lower ends slide in contact with the outer surface of the driving block 6. Through the compression of the protruding end of the driving block 6, the connecting rods 8 and the sliding plates 7 are pushed to move along the inside of the driving cavity 402 and the first spring 9 is compressed. This causes the limiting block 10 to extend through to the outside of the reinforcing block 4 and be inserted into the first limiting groove 11, thereby fixing the reinforcing block 4 between the connection of the first purlin 1 and the second purlin 2 and supporting and reinforcing the connection.

[0024] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 4 As shown, on the side of the two grooves 401 that are far apart from each other, and inside the reinforcing block 4, there are symmetrical movable cavities 403. Both movable cavities 403 are movably connected to a limiting rod 12 that extends through to the outside of the movable cavity 403. A limiting plate 13 is fixedly connected to the outer surface of one end of the limiting rod 12 inside the movable cavity 403. A second spring 14 is fixedly connected between one side of the limiting plate 13 and the inner wall of the movable cavity 403. The second spring 14 is wrapped around the outer surface of the limiting rod 12. One end of the limiting rod 12 that extends through the outside of the movable cavity 403 extends into the inside of the groove 401. A second limiting groove 501 is provided on one side of the outer surface of the rotating rod 5. The end of the limiting rod 12 that extends through to the inside of the groove 401 is inserted into the corresponding second limiting groove 501.

[0025] In this embodiment, the side of the rotating rod 5 with the second limiting groove 501 rotates to the side corresponding to the movable cavity 403. At this time, one end of the limiting rod 12 extends through the groove 401 under the elastic push of the second spring 14 and is inserted into the second limiting groove 501 on the outer surface of the rotating rod 5, thereby restricting the rotation of the rotating rod 5.

[0026] When the purlin reinforcement structure is used, the first purlin 1 and the second purlin 2 are initially connected by engaging the locking block 3 on one side of the first purlin 1 with the locking groove 101 on one side of the second purlin 2. Then, the reinforcement block 4 is slidably engaged between the connection between the first purlin 1 and the second purlin 2. Next, the rotating rod 5 inside the grooves 401 on both sides is rotated, so that the rotating rod 5 drives the driving block 6 to rotate. When the extended arc surfaces at both ends of the driving block 6 rotate to a vertical state, the connecting rods 8 at the upper and lower ends slide in contact with the outer surface of the driving block 6. Through the compression of the protruding end of the driving block 6, the connecting rods 8 and the sliding plate 7 are pushed to move along the inside of the driving cavity 402, and the first spring 9 is compressed. This causes the limiting block 10 to extend through to the outside of the reinforcement block 4 and be inserted into the first limiting groove 11, thereby fixing the reinforcement block 4 between the connection between the first purlin 1 and the second purlin 2 and supporting and reinforcing the connection.

[0027] After the first purlin 1 and the second purlin 2 are supported and reinforced by the reinforcing block 4, the side of the rotating rod 5 with the second limiting groove 501 rotates to the side corresponding to the movable cavity 403. At this time, one end of the limiting rod 12 extends through the groove 401 under the elastic push of the second spring 14 and is inserted into the second limiting groove 501 on the outer surface of the rotating rod 5, thereby restricting the rotation of the rotating rod 5.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
