A lateral locating device includes a body, which is for assembling in a first direction thereof to a first object. The body has in a second direction a fastening portion or a leaning portion for fastening connecting, interfering or bearing in the second direction a second object or another object. Thus, the body can be securely coupled at the first object, and the second object or the another object can be coupled or removed by using the fastening portion or the leaning portion, so as to complete coupling or separation of at least two objects, achieving the effect of repeated quick coupling and separation.

A connecting element for a mechanical joint includes a base part, and a connector part protruding from the base part. The connector part includes a protrusion portion, and a contacting portion extending from the protrusion portion to a direction of the first end of the base part such that a gap is formed between the contacting portion and the front surface of the base part and such that a bottom of the gap is formed by the protrusion portion. The contacting portion includes a front surface which is parallel to the portion of the front surface of the base part in the area of the gap and a back surface facing toward the front surface of the base part.

A fastening assembly having a sliding column and a sliding groove. The sliding column includes a fixing portion provided on a surface of a first installing member facing a second installing member, and an extending portion connected to the fixing portion. The sliding groove is formed on a surface of the second installing member facing the first installing member, and includes an avoiding space for inserting the extending portion into the sliding groove. A fastening space is provided for clamping the extending portion to the sliding groove. A bottom surface of the fastening space is formed with a locking hole. A limiting space is provided for limiting the extending portion from extending from the avoiding space to the fastening space.

A butting structure includes a first connecting portion disposed on the inner surface of a first object and a second connecting portion disposed on the inner surface of a second object. A leading angle is provided at the junction of a top surface and a first side of the first connecting portion. An accommodation space is defined between the top surface and the inner surface of the first object. The second connecting portion includes a bump and a horn structure. The bump is connected to the second object and is disposed corresponding to the accommodation space. The horn structure is connected to the second object and is disposed corresponding to the first connecting portion. A first gap is provided between the bump and the horn structure. An assembling method of the butting structure is also provided.

A concrete embeddable mount for a ledge is provided having a plate with a plurality of keyhole slots therein, four anchors extending from the back of the plate, for embedding the mount in a precast concrete component, wherein the anchors define vertices of a convex quadrilateral, and a fifth anchor extending from the back of the plate, wherein the fifth anchor is positioned within the convex quadrilateral defined by the four anchors. The invention further includes a ledge having a back plate and a perpendicular base extending from the back plate, wherein the back plate has a plurality of rearward extending studs aligned to engage the keyhole slots in the mount plate. Together, the mount and the ledge create a corbel system.

Building or structural panels may be joined, such as to form walls or floors. The panels may be connected in various orientations via one or more connectors. The connectors may mount to anchors associated with the panels. The panels may have outer skins located over an expanded core comprising a matrix of supporting elongate members and voids or openings, with the anchors located at edges of the panels.

An assembled structure includes multiple first assembling units, each of the first assembling units comprising main body parts and connection parts, wherein the main body parts have a profile shape of a polygon having 6n equal-length sides, wherein n is a positive integer; and the connection parts are provided on each equal-length side of each main body part; and the connection parts on each equal-length side are connected to each neighboring first assembling unit by a sliding pair, and the sliding direction of the sliding pair is the same as the extension direction of the sliding pair on the equal-length side on which the sliding pair resides.

A lateral locating device includes a body, which is for assembling in a first direction thereof to a first object. The body has in a second direction a fastening portion or a leaning portion for fastening connecting, interfering or bearing in the second direction a second object or another object. Thus, the body can be securely coupled at the first object, and the second object or the another object can be coupled or removed by using the fastening portion or the leaning portion, so as to complete coupling or separation of at least two objects, achieving the effect of repeated quick coupling and separation.

The present invention relates to a modular frame for CNC machining, comprising: a first side panel and a second side panel, each side panel for with an elongated base with a notch at either end and a vertical extension from the base with a notch at the distal end of the vertical extension; a first crossbeam and a second crossbeam, each crossbeam having a notch at either end, the notches on the crossbeam oriented in an opposing direction to the notches on the side panels; and a gantry beam, the gantry beam having a notch at either end, the notches on the gantry beam oriented in an opposing direction to the notches on the side panels, wherein the side panels, crossbeams and gantry beam are user-assembled into the modular frame via alignment and engagement of the respective notches on the crossbeams and gantry beam with the notches on the side panels, and wherein user assembly of the modular frame is performed without the use of tools.

A fastening device, a fastening system comprising a fastening device and corresponding slots/routs are described. There is a fastening device having at least two sides. In another embodiment the fastening device has three sides. Two of the three sides are about ninety degrees to each other and each of the two sides have a fastener located on its outer surface. There is one corresponding slot for each fastener. Each corresponding slot is on the surface of two separate substrates and located approximately ten millimeters away from an outermost edge of the substrate. The fastener secures with the corresponding slot, consequently joining the two substrates at approximately ninety degrees.
