Detailed Description
The technical solution of the present utility model will be described in further detail with reference to the accompanying drawings, but the scope of the present utility model is not limited to the following description.
As shown in fig. 1-2, the utility model provides a bolt type angle steel purlin supporting system, which comprises a plurality of purlins 1 which are arranged in parallel, two purlin openings 1 which are arranged on the purlins 1 in an up-down symmetrical way, an upper angle steel 2 which is used for connecting the purlins 1 through the purlin openings 1 at the upper end positions of the purlins 1, and a lower angle steel 3 which is used for connecting the purlins 1 through the purlin openings 1 at the upper end positions and the lower end positions of the purlins 1, wherein the upper angle steel 2 is connected end to end, the lower angle steel 3 is connected end to end, and the upper angle steel 2 and the lower angle steel 3 are arranged in parallel. The manufacturing materials of the upper angle steel 2 and the lower angle steel 3 are the same as those of the purline 1, so that the service lives of the materials can be consistent, and the material utilization rate can be effectively improved.
The two ends of one surface of the upper angle steel 2 for horizontal installation are respectively provided with a first installation hole 21 and a second installation hole 22, and the vertical surface of one end of the upper angle steel 2 where the second installation hole 22 is positioned is provided with an installation notch 23 for enabling one end of the second installation hole 22 to penetrate through the purline open hole 1. The second mounting hole 22 penetrates through the purline opening 1 to be vertically opposite to the first mounting hole 21 of the adjacent other upper angle steel 2, and the second mounting hole 22 penetrates through the purline opening 1 to be connected with the first mounting hole 21 of the adjacent other upper angle steel 2 through the connecting piece 4. The apertures of the first mounting hole 21 and the second mounting hole 22 are 8mm or 9mm or 10mm. In this embodiment, the upper angle steel 2 can pass through the purline open hole 1 through the installation notch 23, so that the processing of the purline open hole can be reduced, and the processing efficiency of the purline can be improved by 8%.
The structure and the connection mode of the lower angle steel 3 are the same as those of the upper angle steel 2. The vertical surface is above the horizontal surface when the lower angle steel 3 is connected, and the vertical surface is below the horizontal surface when the upper angle steel 2 is connected. The connecting piece 4 is a pin, and the connecting piece 4 is vertically arranged and simultaneously penetrates through the upper angle steel 2 and the lower angle steel 3, so that the upper angle steel 2 and the lower angle steel 3 are connected to form an upper-lower stable structure. In this embodiment, because the upper angle steel 2 and the lower angle steel 3 on the purline 1 are staggered and stretched, an additional secondary bending moment is necessarily formed on the web of the thin purline 1. If the roof load is large, the axial force of the brace is too large, so that the web plate of the thin-wall purline 1 can be locally buckled and deformed, and even angle steel can penetrate out of the web plate of the purline 1. The connecting piece 4 is arranged to form angle steel bolt type connection by the pin, so that secondary bending moment generated by angle steel can be effectively avoided, the overall stability is better, and the brace force transmission is more direct. The utility model can effectively improve the installation efficiency, ensure the supporting and installing quality between purlins and improve the on-site installation efficiency by about 30 percent.
The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein and is not to be considered as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either by the foregoing teachings or by the teaching of the relevant art. And that modifications and variations which do not depart from the spirit and scope of the utility model are intended to be within the scope of the appended claims.
