The term "two or more" includes two or more than two cases.
[0024] The present application proposes a purlin assembly 10 , which is installed on a house panel to support the house panel and the structure thereon.
[0025] Please refer to Figure 1 The purlin assembly 10 includes: a first purlin 1 and a second purlin 2. The first purlin 1 and the second purlin 2 can be made of cold-bent thin-walled steel, and both the first purlin 1 and the second purlin 2 can be C-shaped steel.
[0026] Exemplarily, the second purlin 2 is connected to the first purlin 1, and the end of the first purlin 1 away from the second purlin 2 is used to support the object being carried. Therefore, when the first purlin 1 supports the object being carried, the second purlin 2 is connected to the end of the first purlin 1 that does not support the object being carried.
[0027] For example, in some usage scenarios, the first purlin 1 and the second purlin 2 are both fixed on the house panel. When the first purlin 1 supports the carried object, the second purlin 2 is fixed on the side of the first purlin 1 facing the ground. Thus, the second purlin 2 can support and reinforce the first purlin 1.
[0028] For example, the projection of the first purlin 1 on the second purlin 2 falls within the second purlin 2. Thus, the force acting on the first purlin 1 can be completely dispersed to the second purlin 2, which is equivalent to increasing the bearing area of the first purlin 1, so as to improve the bearing capacity of the first purlin 1, thereby making the bearing capacity of the first purlin 1 meet the requirements and reducing the risk of failure or damage of the first purlin 1.
[0029] The purlin assembly 10 provided in the embodiment of the present application is provided with the second purlin 2. When the first purlin 1 supports the loaded object at one end away from the second purlin 2, the second purlin 2 can support and reinforce the first purlin 1. The projection of the first purlin 1 on the second purlin 2 falls within the second purlin 2, so as to improve the load-bearing capacity of the first purlin 1, thereby ensuring that the load-bearing capacity of the first purlin 1 meets the requirements and reducing the risk of failure or damage of the first purlin 1.
[0030] In some embodiments, the first purlin 1 and the second purlin 2 are arranged perpendicularly. The second purlin 2 can be arranged horizontally, and the first purlin 1 can be arranged vertically. This allows the force direction of the first purlin 1 to be parallel to the gravity direction, so that the second purlin 2 can better support and reinforce the first purlin 1, thereby improving the bearing capacity of the first purlin 1. This ensures that the bearing capacity of the first purlin 1 meets the requirements, reducing the risk of failure or damage to the first purlin 1.
[0031] In some embodiments, in the horizontal direction, a ratio of a length of a projection of the first purlin 1 on the second purlin 2 to a length of the second purlin 2 is greater than or equal to 1 / 4 and less than or equal to 1 / 2.
[0032] It is understandable that if Figure 1 As shown, in the horizontal direction, the length of the projection of the first purlin 1 on the second purlin 2 is L1, the length of the second purlin 2 is L2, the ratio of L1 to L2 is L1 / L2, and the value range of L1 / L2 is 1 / 4-1 / 2.
[0033] For example, the ratio of L1 to L2 is 1 / 4, or the ratio of L1 to L2 is 3 / 8, or the ratio of L1 to L2 is 1 / 3, or the ratio of L1 to L2 is 1 / 2. When the ratio of L1 to L2 satisfies the above value range, it can be ensured that the projection of the first purlin 1 on the second purlin 2 falls within the second purlin 2. Therefore, the force acting on the first purlin 1 can be completely dispersed to the second purlin 2, which is equivalent to increasing the bearing area of the first purlin 1, so as to improve the bearing capacity of the first purlin 1, thereby ensuring that the bearing capacity of the first purlin 1 meets the requirements and reducing the risk of failure or damage of the first purlin 1.
[0034] In some implementations, the second purlin 2 and the first purlin 1 can be connected by bolt connection, clip connection or plug-in connection, etc. The connection method is relatively simple, which helps to reduce the difficulty of connecting the second purlin 2 and the first purlin 1, and makes the second purlin 2 and the first purlin 1 detachably connected, which is beneficial to the disassembly and subsequent maintenance of the second purlin 2.
[0035] In some implementations, the second purlin 2 and the first purlin 1 can be connected by welding, and welding includes but is not limited to fusion welding or pressure welding, thereby facilitating the enhancement of the connection strength between the second purlin 2 and the first purlin 1 and reducing the risk of separation of the second purlin 2 and the first purlin 1.
[0036] In some implementations, the second purlin 2 and the first purlin 1 may be an integrally formed structural member, thereby enabling the second purlin 2 and the first purlin 1 to be integrally formed, thereby reducing production difficulty and cost.
[0037] In some embodiments, as Figure 1 As shown, the first purlin 1 and the second purlin 2 are closely connected. This allows the first purlin 1 and the second purlin 2 to be tightly connected, thereby ensuring the stability of the connection between the first purlin 1 and the second purlin 2. In particular, when the first purlin 1 supports the load, the force applied to the first purlin 1 is stable, reducing the shaking of the first purlin 1.
[0038] In some embodiments, as Figure 1 As shown, the purlin assembly 10 further includes: a connecting member 3 , which is passed through the connection between the first purlin 1 and the second purlin 2 .
[0039] Thus, the structural strength of the connection between the first purlin 1 and the second purlin 2 can be enhanced by the connector 3 , and the first purlin 1 and the second purlin 2 can be connected by the connector 3 to enhance the connection strength between the first purlin 1 and the second purlin 2 .
[0040] In some embodiments, the connecting members 3 include but are not limited to nails. Thus, the first purlin 1 and the second purlin 2 can be detachably connected by nails, thereby reducing the difficulty of connecting the first purlin 1 and the second purlin 2. In particular, this connection method is simpler, which helps reduce construction difficulty and improve construction efficiency.
[0041] In some other embodiments, the connecting member 3 may also be a bolt. Thus, the first purlin 1 and the second purlin 2 can be detachably connected by the bolt, thereby reducing the difficulty of connecting the first purlin 1 and the second purlin 2. In particular, this connection method is simpler, which helps to reduce construction difficulty and improve construction efficiency.
[0042] In some embodiments, as Figure 1 and Figure 2 As shown, a plurality of connectors 3 are provided, and the plurality of connectors 3 are spaced apart. Thus, by providing a plurality of connectors 3 spaced apart, the structural strength of the connection between the first purlin 1 and the second purlin 2 is enhanced, and the first purlin 1 and the second purlin 2 can be connected through the connectors 3 to enhance the connection strength between the first purlin 1 and the second purlin 2.
[0043] In some embodiments, as Figure 2 As shown, the connection lines of the multiple connectors 3 along the same direction are in a broken line shape. This facilitates enhancing the structural strength of the connection between the first purlin 1 and the second purlin 2, and the connection lines of the multiple connectors 3 along the same direction are in a broken line shape to enhance the shear resistance of the connection between the first purlin 1 and the second purlin 2.
[0044] In other embodiments, the connectors 3 may be arranged in multiple rows or columns in the width direction or the length direction of the first purlin, thereby facilitating enhancing the structural strength of the connection between the first purlin 1 and the second purlin 2 .
[0045] In some embodiments, as Figure 1 As shown, the first purlin 1 includes a first web 11 and a first connecting plate 12 connected to each other, and the second purlin 2 includes a second web 21 and a second connecting plate 22 connected to each other, and the first connecting plate 12 is connected to the second web 21 .
[0046] As a result, the second web 21 can be connected to the first connecting plate 12, so that when the first purlin 1 supports the object at the end away from the second purlin 2, the first connecting plate 12 can be supported and reinforced by the second web 21, and the projection of the first connecting plate 12 on the second web 21 falls within the second web 21, so as to improve the bearing capacity of the first purlin 1, thereby ensuring that the bearing capacity of the first purlin 1 meets the requirements and reducing the risk of failure or damage of the first purlin 1.
[0047] In some implementations, two first connecting plates 12 may be provided, the two first connecting plates 12 being connected to the two ends of the first web 11, and the first connecting plates 12 may be arranged perpendicular to the first web 11. Correspondingly, the second purlin 2 also includes a second web 21 and two second connecting plates 22, the two second connecting plates 22 being connected to the two ends of the second web 21, and the second connecting plates 22 may be arranged perpendicular to the second web 21.
[0048] In some embodiments, as Figure 1 As shown, the first web 11 and the second web 21 are arranged perpendicularly. The second web 21 is arranged in the horizontal direction, thereby making the force direction of the first purlin 1 parallel to the direction of gravity. As a result, the second purlin 2 can better support and reinforce the first purlin 1, thereby improving the bearing capacity of the first purlin 1, thereby ensuring that the bearing capacity of the first purlin 1 meets the requirements and reducing the risk of failure or damage of the first purlin 1.
[0049] In some embodiments, as Figure 1 As shown, the first connecting plate 12 and the second web 21 are arranged in parallel, thereby making the first connecting plate 12 fit better with the second web 21 and making the connection simpler, which helps to reduce construction difficulty and improve construction efficiency.
