Description

Technical Field

[0001] The present application relates to the field of construction, and in particular to a purlin connecting rod and a purlin assembly. Background Art

[0002] Purlins are bending members used to support roof panels or wall panels, perpendicular to the roof frame or beams. Purlins used for roofs are called roof purlins, and purlins used for walls are called wall purlins. Purlins are connected by tie rods and struts to increase the stability of purlins. Tie rods can only bear tension, while struts can bear both tension and pressure.

[0003] The support rod includes a sleeve and steel bars with threads at both ends. The sleeve is sleeved outside the steel bars. The steel bars can be used to withstand tension, and the sleeve is only used to withstand pressure. With this arrangement, the structure of the support rod is complex and the cost is high.

[0004] How to simplify the structure of the purlin connecting rod and reduce the cost is a technical problem that technical personnel in this field need to solve urgently. Utility Model Content

[0005] The purpose of the present application is to provide a purlin connecting rod and a purlin assembly, which simplifies the structure of the purlin connecting rod and reduces the cost.

[0006] In order to solve the above technical problems, the present application provides a purlin connecting rod, including a connecting tube and two fixing parts, the two fixing parts are respectively arranged at the two ends of the connecting tube; the end of the connecting tube is also provided with a fixing plate, the fixing plate and the end of the connecting tube are fixed along the circumference of the connecting tube, the fixing part includes a screw, the screw is used to fix the fixing plate and the purlin, and the outer diameter of the connecting tube is larger than the outer diameter of the screw.

[0007] The end of the connecting pipe is fixed to the fixing plate, and the fixing plate is fixedly connected to the purlin through the fixing part.

[0008] The outer diameter of the connecting pipe is larger than the outer diameter of the screw rod. Therefore, the cross-sectional radius of the connecting pipe is larger, which can effectively improve the stability of the connecting pipe, thereby reducing the probability of bending deformation when providing support between two purlins, thereby ensuring the stability of the overall structure.

[0009] In addition, since the connecting pipe is a tubular structure, compared with the solution with an internal solid structure, it can increase the cross-sectional radius and improve stability while also effectively reducing the overall weight and reducing costs.

[0011] The fixing plate and the end of the connecting tube are fixed along the circumference of the connecting tube. Such an arrangement can ensure the connection stability between the fixing plate and the connecting tube, and when the fixing part transmits the tension or pressure to the fixing plate, the force can be evenly transmitted to the connecting tube, so as to ensure the fixing stability while also ensuring that the connecting tube can withstand the tension and pressure stably.

[0012] Optionally, the fixing plate is located inside the connecting tube, and the outer peripheral wall of the fixing plate is fixed to the inner peripheral wall of the connecting tube by welding along the circumferential direction.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] An embodiment of the present application provides a purlin connecting rod and a purlin assembly, wherein the purlin assembly includes a plurality of purlins and purlin connecting rods arranged in parallel, the purlin connecting rods are connected between two adjacent purlins, the purlin connecting rods can play a connecting role between two adjacent purlins, and can withstand the tension and pressure between two adjacent purlins to ensure the stability of the overall structure.

[0032] Specifically, there is no restriction on the number of purlins and the number of purlin connecting rods, and there is no restriction on the specific setting position of the purlin connecting rods, which can be set according to actual conditions.

[0033] like Figure 1As shown, the purlin connecting rod includes a connecting tube 1 and two fixing parts 2, and the two fixing parts 2 are respectively arranged at both ends of the connecting tube 1. The fixing part 2 includes a fixing plate 11 and a screw 21, wherein the fixing plate 11 is fixed to the end of the connecting tube 1, and the screw 21 is used to fix the fixing plate 11 and the purlin, and the outer diameter of the connecting tube 1 is larger than the outer diameter of the screw 21.

[0034] The end of the connecting pipe 1 is fixed to the fixing plate 11, and the fixing plate is fixedly connected to the purlin through the fixing part 2. In the installed state, the structure between the purlin connecting rod and the two adjacent purlins is relatively stable, and the connecting pipe 1 can directly withstand tension and pressure between the two purlins through the fixing part 2.

[0035] The outer diameter of the connecting pipe 1 is larger than the outer diameter of the screw 21. Therefore, the cross-sectional radius of the connecting pipe 1 is larger, which can effectively improve the stability of the connecting pipe 1, thereby reducing the probability of bending deformation when providing support between two purlins, thereby ensuring the stability of the overall structure.

[0036] In addition, since the connecting pipe 1 is a tubular structure, compared with the solution with an internal solid structure, it can increase the cross-sectional radius and improve stability while also effectively reducing the overall weight and reducing costs.

[0037] Furthermore, since the purlin connecting rod can withstand tension and pressure between two purlins, and compared with the support rods in the prior art, the purlin connecting rod can effectively reduce the cost, in the purlin assembly, the purlin connecting rod can be used as a support rod between purlins, and can also be used as a pull rod between purlins, with high versatility and good flexibility.

[0038] Specifically, in this embodiment, the connecting tube 1 can be a round tube with a circular cross section or a square tube with a square cross section, and no specific limitation is made here. When the connecting tube 1 is a round tube, the outer diameter of the round tube is greater than the outer diameter of the screw 21. When the connecting tube 1 is a square tube, the diameter of the pitch circle where each vertex of the outer periphery of the cross section of the connecting tube 1 is located is greater than the outer diameter of the screw 21.

[0039] The fixing plate 11 and the end of the connecting tube 1 are fixed along the circumference of the connecting tube 1. Such an arrangement can ensure the connection stability between the fixing plate 11 and the connecting tube 1, and when the fixing portion 2 transfers the tension or pressure to the fixing plate 11, the force can be evenly transferred to the connecting tube 1, so as to ensure the fixing stability while also ensuring that the connecting tube 1 can withstand the tension and pressure stably.

[0040] Specifically, Figure 1 and Figure 2As shown, the fixing plate 11 is arranged in the end of the connecting pipe 1 and is fixed to the connecting pipe 1 by welding along the circumferential direction. That is, the shape and size of the outer circumferential wall of the fixing plate 11 and the inner circumferential wall of the connecting pipe 1 can be set to be the same or approximately the same, and the fixing plate 11 is placed in the connecting pipe 1 and fixed by welding along the circumferential direction.

[0041] Of course, the fixing plate 11 can also be fixed outside the connecting pipe 1. In this case, there is no restriction on the structure of the fixing plate 11. The fixing plate 11 is set inside the connecting pipe 1 and fixed by circumferential welding, which can make the overall structure of the purlin connecting rod more regular.

[0042] Alternatively, the fixing plate 11 and the connecting pipe 1 may be provided as an integrally formed structure, and when the two are provided to be fixed by welding, the forming process of the connecting pipe 1 can be simplified. The connecting pipe 1 is a common pipe fitting, which can be cut according to the required length, and the fixing plate 11 can be provided as a standard part, which has good versatility, simplifies the processing technology, and reduces the manufacturing cost.

[0043] like Figure 1 and Figure 2 As shown, the fixing part 2 also includes a gasket 23 and a fixing member, wherein the fixing member is relatively fixed to the screw rod 21, and the purlin is provided with a mounting hole. During installation, the screw rod can pass through the mounting hole and is relatively fixed to the purlin through the fixing member. In the installed state, the fixing member is located on the side of the screw rod 21 away from the fixing plate 11, specifically on the side of the purlin away from the fixing plate 11, and the gasket 23 is sandwiched between the fixing member and the purlin to provide protection for the purlin, while ensuring that the purlin is evenly stressed to avoid damage to the purlin.

[0044] In this embodiment, the connecting pipe 1 is preferably a steel pipe. Of course, there is no restriction on the material of the connecting pipe 1. For example, the connecting pipe 1 can also be set to a pipe fitting made of other materials such as a plastic pipe, as long as the structural strength of the connecting pipe 1 meets the requirements. When the connecting pipe 1 is set to a steel pipe, the overall structural strength of the connecting pipe 1 can be guaranteed, and the service life of the connecting pipe 1 can also be extended.

[0045] Specifically, this embodiment does not limit how the screw rod 21 and the fixing plate 11 are fixed. Six fixing methods between the screw rod 21 and the fixing plate 11 are given below, which can be set according to actual conditions.

[0047] During installation, first pass the rod 26 of the bolt 24 through the through hole 111 of the fixing plate 11, and then weld the fixing plate 11 to the end of the connecting pipe 1, so that the head 25 of the bolt 24 is located on the side of the fixing plate 11 facing the inside of the connecting pipe 1, and the screw rod 21 is located outside the connecting pipe 1.

[0049] The second fixing method is that the screw rod 21 is fixed to the fixing plate 11 by welding. In this case, it can be as follows Figure 2 As shown, the fixing plate 11 is provided with a through hole 111, and the screw rod 21 passes through the through hole 111 and is fixed to the fixing plate 11 along the circumferential direction by welding. Alternatively, the end of the screw rod 21 may be directly fixed to the fixing plate 11 by welding. Alternatively, the fixing portion 2 may include a bolt 24, a rod portion 26 of the bolt 24 is formed with the screw rod 21, and a head portion 25 of the bolt 24 abuts against the outer peripheral wall or the inner peripheral wall of the fixing plate 11 and is fixed by welding along the circumferential direction of the head portion 25 of the bolt 24.

During installation, the stem 26 of the bolt 24 is inserted into the threaded hole 112 after passing through the purlin, and is threadedly matched with the threaded hole 112 to be fixed. At this time, the head 25 of the bolt 24 forms the above-mentioned fixing member.

[0053] A fifth fixing method is that the fixing plate 11 is provided with a through hole 111, and the screw rod 21 passes through the through hole 111, so that one end of the screw rod 21 is located in the connecting pipe 1 and is limited by the fixing nut, and the other end of the screw rod 21 is located outside the connecting pipe 1, and is used to be fixed to the purlin through the mounting nut 22. In the installed state, both ends of the screw rod 21 are limited by the mounting nut 22 and the fixing nut, so that the gasket 23, the purlin and the fixing plate 11 are located between the two nuts.
