Description

Technical Field

[0001] This utility model relates to the field of purlin connection, specifically an assembled purlin connection structure. Background Technology

[0002] Purlins, also known as rafters or purlins, are an important component of building structures. They are roof beams perpendicular to the roof trusses or located horizontally to the rafters. As a crucial component of the roof structure, the primary function of purlins is support. They support roofing materials such as rafters, tiles, wooden planks, or metal sheets, ensuring these materials can stably cover the roof and provide shelter from wind and rain.

[0003] In existing technologies, purlins are mainly used to connect with roof tiles, planks, and other roof components to ensure the roof can be used normally and smoothly. Purlins also support the roof components, allowing their weight to be smoothly transferred and distributed to the load-bearing columns, ensuring the stability of the tiles, planks, and other components. However, most purlins are connected to steel structures by welding. Welding not only requires high precision but also has a long overall construction period, which can reduce the installation efficiency of purlins. Furthermore, welding makes it difficult to move the purlins after installation and can easily damage the anti-corrosion layer on the surface of the steel structure. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, most purlins are connected to steel structures by welding. However, welding not only requires high precision but also has a long overall construction period, which can reduce the installation efficiency of purlins. Furthermore, welding makes it difficult to move the purlins after installation. This utility model proposes a prefabricated purlin connection structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a prefabricated purlin connection structure, including a truss upper purlin, a hot-dip galvanized angle steel purlin support is provided at the top of the truss upper purlin, a purlin body is provided on one side of the hot-dip galvanized angle steel purlin support, a hot-dip galvanized U-bolt is movably inserted into the inner cavity of the hot-dip galvanized angle steel purlin support, a hot-dip galvanized bolt connecting washer is slidably connected to the surface of the hot-dip galvanized U-bolt, and a hot-dip galvanized nut sleeve is threadedly connected to the surface of the hot-dip galvanized U-bolt.

[0006] Preferably, a hot-dip galvanized nut washer is slidably connected to the surface of the hot-dip galvanized U-bolt, and the hot-dip galvanized nut washer is disposed between the bottom of the hot-dip galvanized bolt connecting pad and the top of the hot-dip galvanized nut sleeve.

[0007] Preferably, one side of the hot-dip galvanized angle steel purlin bracket is threaded with a fixing bolt, and the surface of the fixing bolt is threadedly connected to the inner cavity of the purlin body.

[0008] Preferably, the bottom of the purlin body intersects with the top of the upper truss member, and the angle between the top of the purlin body and the top of the upper truss member is 90 degrees.

[0009] The advantages of this utility model are:

[0010] This invention connects hot-dip galvanized U-bolts to the inside of the hot-dip galvanized angle steel purlin bracket and simultaneously to the surface of the upper purlin of the truss. The hot-dip galvanized U-bolts are then securely connected to the outside of the upper purlin using a hot-dip galvanized bolt connecting plate and a hot-dip galvanized nut. This achieves stable installation of the hot-dip galvanized angle steel purlin bracket and the purlin body, improving installation efficiency and simplifying the process. It also minimizes the impact on the anti-corrosion coating on the upper purlin surface and reduces the workload of workers. Furthermore, it solves the problem of welding, a common method for connecting purlins to steel structures. Welding requires high precision, has a long construction period, reduces installation efficiency, and makes the purlin difficult to move after installation. Attached Figure Description

[0015] 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 scope of protection of the present utility model.

[0016] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0017] This application discloses a prefabricated purlin connection structure. (Refer to...) Figure 1 and Figure 2 A prefabricated purlin connection structure includes a truss upper purlin 6, a hot-dip galvanized angle steel purlin support 1 at the top of the truss upper purlin 6, a purlin body 5 on one side of the hot-dip galvanized angle steel purlin support 1, a hot-dip galvanized U-bolt 2 movably inserted into the inner cavity of the hot-dip galvanized angle steel purlin support 1, a hot-dip galvanized bolt connection washer 3 slidably connected to the surface of the hot-dip galvanized U-bolt 2, and a hot-dip galvanized nut sleeve 8 threadedly connected to the surface of the hot-dip galvanized U-bolt 2.

[0018] When the hot-dip galvanized U-bolt 2 is inserted into the interior of the hot-dip galvanized angle steel purlin bracket 1 and fitted onto the surface of the upper purlin 6 of the truss, the hot-dip galvanized angle steel purlin bracket 1 can be smoothly connected to the top of the upper purlin 6 of the truss. At the same time, the connection between the hot-dip galvanized bolt connecting washer 3 and the hot-dip galvanized U-bolt 2 can effectively increase the stability of the hot-dip galvanized U-bolt 2 during use. When the hot-dip galvanized nut sleeve 8 is connected to the surface of the hot-dip galvanized U-bolt 2, the connection between the hot-dip galvanized U-bolt 2 and the upper purlin 6 of the truss can be more stable. This not only allows the hot-dip galvanized angle steel purlin bracket 1 and the purlin body 5 to be used stably, but also makes it less prone to shaking when the connection between the hot-dip galvanized U-bolt 2 and the upper purlin 6 of the truss. In addition, multiple hot-dip galvanized nut sleeves 8 can be used when connected to the hot-dip galvanized U-bolt 2, thereby increasing the tightness of the connection between the hot-dip galvanized U-bolt 2 and the upper purlin 6 of the truss.

[0019] Reference Figure 1 and Figure 2 A hot-dip galvanized nut washer 4 is slidably connected to the surface of the hot-dip galvanized U-bolt 2. The hot-dip galvanized nut washer 4 is located between the bottom of the hot-dip galvanized bolt connecting washer 3 and the top of the hot-dip galvanized nut sleeve 8. The hot-dip galvanized nut washer 4 can not only further increase the connection stability between the hot-dip galvanized nut sleeve 8 and the hot-dip galvanized U-bolt 2, but also reduce the wear between the hot-dip galvanized nut sleeve 8 and the hot-dip galvanized bolt connecting washer 3.

[0020] Reference Figure 1 and Figure 2One side of the hot-dip galvanized angle steel purlin bracket 1 is threaded with a fixing bolt 7. The surface of the fixing bolt 7 is threaded with the inner cavity of the purlin body 5. The hot-dip galvanized angle steel purlin bracket 1 can be connected to the purlin body 5 through the fixing bolt 7, so as to realize the normal installation of the purlin body 5 and enable it to be used smoothly in the future. At the same time, it increases the stability and firmness of the purlin body 5 during use.

[0021] Reference Figure 1 and Figure 2 The bottom of the purlin body 5 intersects with the top of the upper purlin 6 of the truss, and the angle between the top of the purlin body 5 and the top of the upper purlin 6 is 90 degrees. The intersecting arrangement between the purlin body 5 and the upper purlin 6 ensures that the connection and use of the purlin body 5 and the upper purlin 6 are sufficiently stable when they are connected, thereby increasing the sturdiness of the purlin body 5 during use.

[0022] Working Principle: When using this device, the operator can place the hot-dip galvanized angle steel purlin bracket 1 on the top of the truss upper beam 6, then insert the hot-dip galvanized U-bolt 2 into the inner cavity of the hot-dip galvanized angle steel purlin bracket 1 and fit it onto the surface of the truss upper beam 6. After completing the above operation, the hot-dip galvanized bolt connecting washer 3 can be inserted into the surface of the hot-dip galvanized U-bolt 2, and the hot-dip galvanized nut washer 4 can be slid onto the surface of the hot-dip galvanized U-bolt 2. When the hot-dip galvanized bolt connecting washer 3 and the hot-dip galvanized nut washer 4 are connected to the hot-dip galvanized U-bolt 2, the hot-dip galvanized nut washer 4 should be placed at the bottom of the hot-dip galvanized bolt connecting washer 3. After that, the hot-dip galvanized nut sleeve 8 can be threaded onto the surface of the hot-dip galvanized U-bolt 2. After completing the above operation, the hot-dip galvanized angle steel purlin bracket 1 and the purlin body 5 are connected together by the fixing bolt 7. At this time, the normal installation and use of the hot-dip galvanized angle steel purlin bracket 1 and the purlin body 5 can be completed.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
