Description

Technical Field

[0001] The invention relates to the technical field of roof suspension, and in particular to a joint type roof hanging point locking device and an installation assembly. Background Art

[0002] Metal roof panels commonly used in buildings are mainly divided into the following three types based on the installation method: nailing, snap-on and seam-type. Seam-type roof refers to the adjacent roof panels being locked together along the longitudinal edges of the panels during installation, forming different seam structures perpendicular to the roof. The panels are connected by the seam structure. Generally, the seam roof is roughly divided into vertical seam roof 9, diamond seam roof 9 and spherical seam roof 9 according to the different shapes of the seam structure. The so-called diamond seam roof means that the cross-sectional shape of its seam structure 9 is as follows: Figure 1b The so-called standing seam roof, that is, the cross-sectional shape of the seam structure 9 is as shown Figure 1a The shape shown; and the so-called spherical joint roof that is, the cross-sectional shape of the joint structure 9 is as shown Figure 1c Shape shown.

[0003] When performing construction and other operations, it is necessary to install the joint type roof hanging point locking device on the joint roof 9. When the existing locking device is installed, the joint roof is easy to fall off from the installation groove of the locking device, which poses a hidden danger to human life safety. In addition, the existing locking device has a connecting hole, and screws pass through the connecting hole to lock multiple locking devices on the external connecting piece. First, the screw passing through the connecting hole will cause damage to the roof, and second, the connecting hole of the locking device corresponds to the opening on the external connecting piece. The screw can only fix the locking device to the fixed position of the external connecting piece through the connecting hole and the opening, and the installation direction is relatively single.

[0004] Therefore, it is necessary to provide a new mounting assembly. Utility Model Content
