A mounting device or clamp is provided that can be secured to a roof joint without damaging the roof joint. Two roof panels can be joined at a roof joint that extends away from the roof. The clamp has a body with a slot to receive the roof joint. An insert of the clamp is rotatable relative to the body from a first position to a second position. The clamp body can be positioned over the roof joint, and the insert can rotate or pivot from the first position to the second position relative to the body to secure the clamp to the roof joint. In one embodiment, a body of the clamp has a first arm that is concave and the insert has a concave portion to engage the roof joint. Alternatively, in another embodiment, the insert can be connected to the clamp body such that either a first projection or a second projection of the insert faces a roof joint.

The present invention relates to a clamp assembly for securing a variety of equipment. The clamp assembly comprises a top portion, a bottom portion, a first side and a second side. The top portion comprises a first surface and a second surface separated by a first channel that is configured to receive an accessory. The bottom portion has a cavity for mounting the clamp assembly on a structure. The first side comprises a first securing hole and a second securing hole, each configured to receive a first securing means and a second securing means. The second side comprises a second channel for receiving the accessory and a first blind hole and a second blind hole for securing the first securing means and the second securing means received through the first securing hole and the second securing hole.

Embodiments herein disclose a universal clamp assembly for clamping a solar panel. The universal clamp assembly comprises a securing means to secure a support structure, the support structure configured to couple with a rail of the solar panel and a shock absorbing member disposed between the securing means and the support structure to keep the securing means in place during installation. The securing means comprises a first channel, a second channel, a first securing hole, at least one first hole, at least one first pin, a protruding structure and a grooved wall. The support structure comprises a second securing hole to secure a securing member disposed through the first securing hole of the securing means, thereby joining the securing means and the support structure, a first lateral wall, a second lateral wall, a first coupling member and a second coupling member to secure the universal clamp assembly in the rail.

An interlocking panel system for covering a base surface with interlocking panels to prevent water ingress is provided. A first panel includes a sheet-like section, a receptacle connected to the sheet-like section, a first projection and a second projection. An interlock includes an interlock hook portion and an interlock receiving portion with the interlock configured to be inserted into the receptacle of the first panel and at least one of the interlock hook portion or the receptacle preventing the interlock from being withdrawn from the first panel. A second panel includes a sheet-like portion and a second panel hook portion configured to be inserted into the interlock receiving portion and engage with the second projection of the first panel. At least one of the second panel hook portion or the second projection preventing the second panel from being withdrawn from the first panel and/or interlock.

A building panel is constructed of a corrugated material. The panel can be folded into a U-shaped configuration. Successive folded panels can be coupled together using complementary shaped corrugations to fix panels in position relative to each other. Shaped connectors can be used to connect building panels in one plane to building panels in another plane.

A clip for electrically bonding a pair of adjacently-disposed metal panels is disclosed. One embodiment entails such a clip (104) including a first clip member (112) and an oppositely disposed second clip member (116). The surface (114) of the first clip member (112) that faces the second clip member (116) includes at least one grounding projection (128), while the surface (118) of the second clip member (116) that faces the first clip member (112) also includes at least one grounding projection (128). The clip (104) may be installed on a standing seam (102) of a panel assembly (100), with its first clip member (112) engaging one of the metal panels 82″ that define this stand seam (102) and with its second clip member (116) engaging the other of the metal panels 82″ that define this same standing seam (102).
