Problems solved by technology

[0004] The connection between purlins generally uses angle steel as the connecting piece. If the bolt connection scheme is used to connect the purlins, the angle control of each angle steel connection point is required. The factory or the site is required to perform blanking processing according to the angle of the purlin connection, and Corresponding to the specific number for construction and installation, this has caused great difficulties for design deepening, factory cutting and on-site construction and installation

Embodiment Construction

[0014] The overall structure schematic diagram of the present invention is as figure 1 , figure 2 shown. image 3 For the enlarged three-view structural diagram of the fixing clip 2, the upper and lower ends of the fixing clip are shown with the same circumferential ribs 7.

[0015] It can be seen from the figure that a metal roof multi-angle purlin connector includes two hinge pieces 1 / 3 that can be rotated and separated around the pin shaft 5 and the pin shaft 5 connecting the two hinge pieces. It is characterized in that: the pin Between the first hinge piece 1 and the second hinge piece 3 connected in series on the shaft 5, there is also a cylindrical fixing clip 2 connected in series; between the first hinge piece 1 and the fixing clip 2 , and the joint surface between the fixed clip 2 and the second hinge 3 are provided with the same circumferential ribs; the lower surface of the first hinge 1 is provided with circumferential ribs The ribs 7 and the circumferential r...

Abstract

The invention relates to a metal roof multi-angle purlin connector, which aims to solve the technical problems of realizing multi-angle purlin connection by cold treatment and convenient on-site installation, and belongs to the technical field of metal roof construction. It is characterized in that, the first hinge piece, the cylindrical fixing clip and the second hinge are connected in series on the pin shaft, between the first hinge piece and the fixed clip, and between the fixed clip and the second hinge. The connecting surfaces between the sheets are provided with the same annular rib, which can be engaged and connected with each other. The positive effects of the present invention are: the present invention optimizes the design of the hinge-like profile member, and after being fastened by the pin spring nut, the annular rib is meshed and fastened with each other without rotation; not only can the welding process be avoided, but also During on-site installation, the purlin can be connected with various angles to meet the installation of special-shaped and complex building shapes. The invention has simple and reasonable structure, convenient installation, very firm connection and good overall safety.

Description

technical field [0001] The invention relates to a metal roof purlin connector, in particular to a multi-angle purlin connection for a special-shaped hyperbolic roof, and belongs to the technical field of construction engineering. Background technique [0002] With the development of my country's steel structure buildings, metal roofs are widely used in various airports, stadiums (stadiums), exhibition halls, stations and other large public buildings. Since most large public buildings are special-shaped and complex steel structures, and the main steel structure is mostly a long-span structure, it cannot be installed by the usual roof installation method, and it is necessary to design additional purlins on the basis of the original steel structure. [0003] In order to meet the installation stress requirements of metal roof panels or profiled steel plates, metal roof purlins are usually connected by welding or angle steel connection. However, since the metal roof is often equ...
