Description

Technical Field

[0001] This utility model belongs to the field of building engineering, and specifically relates to a purlin combination 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 (usually bi-directional bending) members, and are generally designed as single-span simply supported purlins. Commonly used purlins are solid web type and light steel truss type.

[0003] Currently, there are many new photovoltaic and air conditioning projects being added to existing roofs. Many of these roofs were originally designed with simply supported C-shaped purlins, which have limited load-bearing capacity and are difficult to meet the load-bearing requirements of new projects. Methods such as directly increasing the purlin cross-section, replacing the purlins, or densifying the purlins involve roof demolition, which is extremely costly and prevents many new roof projects from being implemented. Therefore, how to reinforce existing purlins to improve their load-bearing capacity is of great practical value. Utility Model Content

[0007] Furthermore, the pair of C-shaped reinforcing plates are detachably locked to the simply supported C-shaped purlin by a second bolt and a first nut.

[0008] Furthermore, the C-shaped reinforcing plate at the lower end is also secured to the simply supported C-shaped purlin by a third bolt.

[0009] Furthermore, the guide shaft slidably passes through the lower sidewall of the upper C-shaped reinforcing plate and is fixedly connected to the upper sidewall of the lower C-shaped reinforcing plate.

[0010] Furthermore, the guide shaft is threadedly connected to the side wall of the C-shaped reinforcing plate at the lower end.

[0011] Furthermore, the upper end face of the guide shaft is provided with an internal hexagonal hole; or, the upper outer surface of the guide shaft is hexagonal.

[0012] Furthermore, L-shaped fixing seats are provided on the outer sides of two adjacent simply supported C-shaped purlins, and screws are provided on the vertical connecting plates of the L-shaped fixing seats and the opposite surfaces of the simply supported C-shaped purlins; connecting plates are provided on the outer sides of a pair of C-shaped reinforcing plates; the screws pass through the simply supported C-shaped purlins and the C-shaped reinforcing plates and are connected to the connecting plates; the L-shaped fixing seats and the connecting plates further reinforce the two adjacent simply supported C-shaped purlins.

[0013] Furthermore, the vertical connecting plate of the L-shaped fixing seat is also locked to the simply supported C-shaped purlin by a fourth bolt.

[0028] Further, see Figure 4-5 As shown (the dashed box in the figure represents a uniform type of hole), in this embodiment, a first through hole 21 is provided on a pair of C-shaped reinforcing plates 2, and a second through hole 101 adapted to the first through hole 21 is provided on the simply supported C-shaped purlin 1; during installation, refer to... Figure 1-3As shown, after a pair of C-shaped reinforcing plates 2 are installed inside the simply supported C-shaped purlin 1, the second bolt 5 passes through the second through hole 101 and the first through hole 21 in sequence, and its front end is screwed into the first nut 6 and tightened, so as to detachably lock the pair of C-shaped reinforcing plates 2 onto the simply supported C-shaped purlin 1.

[0029] Further, see Figure 4-5 As shown, in this embodiment, the C-shaped reinforcing plate 2 at the lower end is also provided with a third through hole 22, and the simply supported C-shaped purlin 1 is also provided with a first threaded hole 102 that matches the third through hole 22; during installation, refer to... Figure 1-3 As shown, after the third bolt 7 passes through the third through hole 22, its front end is locked into the first threaded hole 102, thereby locking the C-shaped reinforcing plate 2 located at the lower end into the simply supported C-shaped purlin 1.

[0030] Further, see Figure 5 As shown, in this embodiment, a fourth through hole 23 is provided on the lower side wall of the upper C-shaped reinforcing plate 2, and a second threaded hole 24 is provided on the upper side wall of the lower C-shaped reinforcing plate 2; while the lower outer surface of the guide shaft 3 is provided with external threads; during installation, refer to... Figure 4 As shown, the guide shaft 3 can slide through the fourth through hole 23 and its lower end is screwed into the second threaded hole 24, thereby fixing the guide shaft 3 to the upper side wall of the C-shaped reinforcing plate 2 at the lower end. In this embodiment, in order to facilitate screwing the guide shaft 3 into the second threaded hole 24, the upper end face of the guide shaft 3 is provided with an internal hexagonal hole; or, the upper outer surface of the guide shaft 3 is hexagonal.

[0031] Further, see Figure 3 and Figure 5 As shown, in this embodiment, L-shaped fixing seats 8 are provided on the outer sides of two adjacent simply supported C-shaped purlins 1. A screw 9 is provided on the vertical connecting plate of the L-shaped fixing seat 8 opposite to the simply supported C-shaped purlin 1, and the screw 9 is fixedly connected to the vertical connecting plate of the L-shaped fixing seat 8. A connecting plate 10 is provided on the outer sides of a pair of C-shaped reinforcing plates 2, and a seventh through hole 1001 is provided on the connecting plate 10. During installation, refer to... Figure 4-5 As shown, the simply supported C-shaped purlin 1 has a fifth through hole 103, and the pair of C-shaped reinforcing plates 2 have a sixth through hole 25. (See also...) Figure 1 and Figure 3As shown, the screw 9 passes through the fifth through hole 103 and the sixth through hole 25 in sequence, and then its front end passes through the seventh through hole 1001 on the connecting plate 10. After passing through, the second nut 12 is screwed in to lock it in place. This allows the simply supported C-shaped purlin 1 and a pair of C-shaped reinforcing plates 2 to be clamped and fixed between the L-shaped fixing seat 8 and the connecting plate 10. This further reinforces the two adjacent sections of the simply supported C-shaped purlin 1 through the L-shaped fixing seat 8 and the connecting plate 10.

Figure 2-3 As shown, after the fourth bolt 11 passes through the eighth through hole 81, its front end is locked into the third threaded hole 104, thereby locking the L-shaped fixing seat 8 onto the simply supported C-shaped purlin 1.

[0033] The installation steps of this utility model are as follows:

[0034] 1) Place a C-shaped reinforcing plate 2 on the lower inner side of two adjacent simply supported C-shaped purlins 1, and align the third through hole 22 with the first threaded hole 102, then lock in the third bolt 7. At this time, the third bolt 7 should not be fully tightened, so that the C-shaped reinforcing plate 2 at the lower end and the C-shaped purlin 1 can move freely. The third bolt 7 avoids the problem of needing special operators to straighten the C-shaped reinforcing plate 2 at the lower end to prevent it from flipping, falling off or becoming misaligned, thus freeing up manpower.

[0035] 2) Pass the second bolt 5 through the second through hole 101 on the lower C-shaped reinforcing plate 2 and the first through hole 21 on the two adjacent simply supported C-shaped purlins 1 in sequence, screw the first nut 6 into its front end and tighten it, and then tighten the third bolt 7.

[0036] 3) Place another C-shaped reinforcing plate 2 on top of the previously installed C-shaped reinforcing plate 2, and after inserting the guide shaft 3 and the first bolt 4, rotate the first bolt 4 to make it rotate upward, thereby pushing the upper C-shaped reinforcing plate 2 upward and aligning the second through hole 101 on the upper C-shaped reinforcing plate 2 with the first through hole 21 on the two adjacent simply supported C-shaped purlins 1; by setting the guide shaft 3 and the first bolt 4, the problem of requiring special operators to continuously lift and straighten the upper C-shaped reinforcing plate 2 during the installation process is avoided, thus freeing up manpower and enabling fine-tuning of the position of the upper C-shaped reinforcing plate 2, thereby improving installation efficiency;

[0037] 4) After passing the second bolt 5 through the second through hole 101 on the upper C-shaped reinforcing plate 2 and the first through hole 21 on the two adjacent simply supported C-shaped purlins 1, screw the first nut 6 into its front end and tighten it.

[0038] 5) After the screw 9 on the L-shaped fixing seat 8 passes through the first through hole 21 on the two adjacent simply supported C-shaped purlins 1 and the sixth through hole 25 on the pair of C-shaped reinforcing plates 2, the L-shaped fixing seat 8 is locked to the simply supported C-shaped purlin 1 by the fourth bolt 11. The fourth bolt 11 avoids the problem of needing special operators to straighten the L-shaped fixing seat 8 in order to prevent it from falling off, thus freeing up manpower.

[0039] 6) After inserting the connecting plate 10 into the screw 9 through its seventh through hole 1001, screw the second nut 12 into the front end of the screw 9 and lock it in place.
