Description

Technical Field

[0001] The utility model relates to the technical field of multi-angle purlin connection of metal roofs, in particular to a multi-angle purlin connector for metal roofs. Background Art

[0002] Since most large public buildings are complex steel structures with special shapes, and the main steel structures are mostly large-span structures, they cannot be installed using the usual roof installation method, and additional purlins need to be designed on the basis of the original steel structure. Metal roofs are often equipped with thermal insulation cotton and membrane structures, which are mostly flammable items. Sparks will inevitably fall during welding, and there is a possibility of fire. Therefore, in order to eliminate fire hazards, the roof purlin connection method is usually not welded, but cold connection methods such as bolt connection and self-tapping screw connection are used instead.

[0003] The connection between existing metal roof purlins is usually made of angle steel as a connector. When the purlins need to be connected at a certain angle, bolts are required to be threadedly connected in conjunction with threaded mounting holes to achieve the connection and fixation between the purlins. The angle is controlled by the angle of the threaded mounting holes on the angle steel. Therefore, when different angle connection requirements are met, angle steel connectors with corresponding angles need to be processed, which is very troublesome to use. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, such as: the connection between the existing metal roof purlins is usually connected with angle steel as a connecting piece. When the purlins need to be connected at a certain angle, bolts are required to be used in a threaded connection manner in conjunction with threaded mounting holes to achieve the connection and fixation between the purlins. The control of the angle is achieved by the angle of the threaded mounting holes on the angle steel. Therefore, when different angle connection requirements are met, angle steel connecting pieces with corresponding angles need to be processed, which is very troublesome to use.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0013] 1. By rotating the limit piece and the threaded rod with the hexagonal groove, the distance between the upper fixing mechanism and the lower fixing mechanism can be adjusted and fixed.

The operation is simple and easy to use, which can save a lot of purlin installation time and improve overall work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-Figure 8 A multi-angle purlin connector for a metal roof comprises an upper fixing mechanism 1, a multi-angle connecting portion 2, a connecting mechanism 3, a lower fixing mechanism 4 and a switching mechanism 5, wherein the two multi-angle connecting portions 2 are respectively rotatably connected to the two sides of the upper fixing mechanism 1, one end of the two connecting mechanisms 3 is respectively rotatably connected to the two multi-angle connecting portions 2, one end of the two connecting mechanisms 3 away from the multi-angle connecting portions 2 is respectively rotatably connected to the two sides of the lower fixing mechanism 4, the upper fixing mechanism 1 is limitedly connected to the lower fixing mechanism 4, one switching mechanism 5 is used for installation and fixation between the upper fixing mechanism 1 and the multi-angle connecting portion 2, and the other switching mechanism 5 is used for installation and fixation between the connecting mechanism 3 and the lower fixing mechanism 4.

[0027] The upper fixing mechanism 1 includes an upper base plate 11, two first connecting ends 12 are provided on both sides of the upper base plate 11, a limiting groove 13 is provided in the upper base plate 11, a limiting member 131 is rotatably connected in the limiting groove 13, a threaded rod 132 is fixedly connected to one end of the limiting member 131, and a hexagonal groove 133 is provided on the surface of the side of the limiting member 131 away from the threaded rod 132.

[0028] The multi-angle connecting part 2 includes a mounting plate 21, a second connecting end 22 is provided on one end of the mounting plate 21 close to the upper base plate 11, a hollow groove 23 is provided on the mounting plate 21, threaded holes 231 and positioning holes 232 are respectively provided on the two inner side walls of the hollow groove 23, a first positioning bolt 233 passing through the positioning hole 232 and the hollow groove 23 is connected to the inner thread of the threaded hole 231, and a twisting end 234 is provided on one end of the first positioning bolt 233.

[0029] The connecting mechanism 3 includes a connecting plate 31, and a third connecting end 32 is provided on one end of the connecting plate 31 close to the mounting plate 21. The third connecting end 32 is located in the empty groove 23, and the third connecting end 32 is rotatably connected to the first positioning bolt 233. A fourth connecting end 33 is provided on one end of the connecting plate 31 away from the third connecting end 32.

[0030] Since the connecting plate 31 is rotatably connected to the empty groove 23 through the third connecting end 32, the first positioning bolt 233, the threaded hole 231 and the positioning hole 232, it is only necessary to rotate the twisting end 234 to release the threaded connection between the first positioning bolt 233 and the threaded hole 231, and then the first positioning bolt 233 can be pulled out from the mounting plate 21, and the connection and disassembly between the multi-angle connecting part 2 and the connecting mechanism 3 can be completed. Conversely, the first positioning bolt 233 is passed through the positioning hole 232 and the third connecting end 32 in turn and then threadedly connected to the threaded hole 231, and the installation and connection between the multi-angle connecting part 2 and the connecting mechanism 3 can be completed. Both the disassembly and installation processes are very simple and convenient.

[0031] The lower fixing mechanism 4 includes a lower base plate 41 , two fifth connecting ends 42 are provided on both ends of the lower base plate 41 , an internal threaded tube 43 is fixedly connected to a side wall of the lower base plate 41 close to the upper base plate 11 , and the internal threaded tube 43 is threadedly connected to the threaded rod 132 .

[0032] Since the upper fixing mechanism 1 and the multi-angle connecting part 2 are rotatably connected, the multi-angle connecting part 2 and the connecting mechanism 3 are rotatably connected, the connecting mechanism 3 and the lower fixing mechanism 4 are rotatably connected, and the upper fixing mechanism 1 and the lower fixing mechanism 4 are limited and fixed by the threaded connection between the internal threaded tube 43 and the threaded rod 132, therefore, by rotating the limit member 131 and the threaded rod 132 with the help of the hexagonal groove 133, the distance between the upper fixing mechanism 1 and the lower fixing mechanism 4 can be adjusted and fixed. As the distance between the upper fixing mechanism 1 and the lower fixing mechanism 4 is adjusted, the angle of the multi-angle connecting part 2 and the connecting mechanism 3 will change accordingly. Therefore, the multi-angle connecting part 2 can realize multi-angle adjustment within a certain range, thereby meeting different requirements for connection angles during purlin installation. By replacing the connecting mechanisms 3 of different lengths, the angle adjustment range can be further adjusted, thereby further increasing the adjustable angle range.

[0033] After the angle adjustment is completed, the upper fixing mechanism 1 and the lower fixing mechanism 4 can be regarded as being fixedly connected through the threaded rod 132 and the internal threaded tube 43, and the upper fixing mechanism 1 and the lower fixing mechanism 4 can be regarded as a whole. At this time, each multi-angle connecting part 2 and the connecting mechanism 3 form a stable triangular structure with the upper fixing mechanism 1 and the lower fixing mechanism 4. Therefore, the multi-angle purlin connector has high structural strength, strong load-bearing capacity, and is not easy to deform and damage.

[0034] The transfer mechanism 5 includes a fixing plate 51, a second positioning bolt 52 and a nut 53. The two second positioning bolts 52 are fixedly connected to one side surface of the fixing plate 51. In the rotational connection between the upper fixing mechanism 1 and the multi-angle connecting part 2, one end of the second positioning bolt 52 passes through the first connecting end 12 and the second connecting end 22, and the nut 53 is threadedly connected to one end of the second positioning bolt 52 passing through the first connecting end 12 and the second connecting end 22. In the rotational connection between the connecting mechanism 3 and the lower fixing mechanism 4, one end of the second positioning bolt 52 passes through the fifth connecting end 42 and the fourth connecting end 33, and the nut 53 is threadedly connected to one end of the second positioning bolt 52 passing through the fifth connecting end 42 and the fourth connecting end 33. A gasket 531 is provided on the nut 53.

[0035] With the help of the adapter mechanism 5, the rotational connection between the upper fixing mechanism 1 and the multi-angle connecting part 2 and between the connecting mechanism 3 and the lower fixing mechanism 4 can be easily and conveniently completed. It is only necessary to rotate the nut 53. By removing the nut 53 from the second positioning bolt 52, the second positioning bolt 52 can be conveniently taken out to complete the quick installation connection between the upper fixing mechanism 1 and the multi-angle connecting part 2 and between the connecting mechanism 3 and the lower fixing mechanism 4. The operation is simple and easy to use, which can save a lot of purlin installation time and improve overall work efficiency.
