A composite element (10) for use in construction, in particular building construction or civil engineering, which composite element comprises at least two components and at least one fastening element (11) for connecting the components. A first component has at least one assembly pin (13), which is cylindrical in particular. The fastening element (11) is configured as a clamping element such that it can be force-fittingly connected to the assembly pin (13). The invention further relates to a use of a fastening element (11) configured as a clamping element.

A standoff assembly for separating a first component from a second component from one another a predetermined distance includes a standoff having a predetermined length defined between a first end and a second end, and an anti-rotational structure formed at the first end. The anti-rotational structure is configured to be inserted into a corresponding opening formed in the first component. The standoff assembly further includes a first fastener to secure the first component to the first end of the standoff and a second fastener to secure the second component to the second end of the standoff. A method for separating a first component from a second component is further disclosed.

A coupling for connecting a circuit board to a mount with a fastener. The mount may be connected to a component. The fastener includes a first snap-fit connection formation for establishing a snap-fit connection with a second snap-fit connection formation provided on the mount. When connected, the fastener clamps the circuit board against the mount. The fastener further includes a first engagement formation configured to engage with a second engagement formation on the mount for bracing the snap-fit connection.

The sensor adaptor includes a case body of which a front end is closed and a rear end is open, a cap body being engageable with the rear end of the case body, a seal member interposed between the case body and the cap body, and a fixing portion configured to fix the case body to the mounting portion. A part of the sensor is inserted into an accommodation space of the case body, and the remaining portion of the sensor is drawn out to the outside via an opening of the cap body. The seal member is disposed on a rear end side of the case body to surround the sensor. The seal member is brought into close contact with the case body and the sensor. Accordingly, a gap between the part of the sensor and the case body is sealed from an external space by the seal member.

A rebar anchoring system and method are provided. The system includes: a rebar, with an external thread formed on the periphery of at least one end; an anchoring head, with a first perforation and a second perforation disposed respectively at both ends extending axially into the anchoring head and communicating with each other, the inner sides of the first and second perforations being formed respectively with a first internal thread matching with the external thread of the rebar and a second internal thread, and the anchoring head being mounted on the end of the rebar through the first internal thread and the external thread of the rebar; and a bolt, having a screw rod matching with the second internal thread, the screw rod being locked into the second perforation of the anchoring head, and the end of the screw rod pressing against the end of the rebar.

A clamp device for mounting equipment to a support structure including a base and a slider. The base includes a first trough formed in the front side of the base and a second trough formed in the back side of the base and a first coupling element located on the first lateral side and a second coupling element located on the second lateral side of the base. Each of the first and second coupling elements extend from near the top end of the base towards the bottom end of the base at an angle relative to the first trough. The slider includes a channel on a back side of the slider and corresponding coupling elements within the channel configured to slidingly engage the first and second coupling elements upon association of the slider with the base.

A stretchable rod structure and a method of mounting the same on an object are introduced. The stretchable rod structure has a fitting member and a rod member. The fitting member has a first fitting portion or first abutting portion. The first fitting portion or first abutting portion is adapted to fit to or abut against a first object. The rod member is movably fitted to the fitting member. The rod member has a second fitting portion or second abutting portion. The second fitting portion or second abutting portion is adapted to fit to or abut against a second object. Therefore, the stretchable rod structure can be fitted to the first object and the second object, thereby allowing two objects to be fitted together, moved or separated.

A rebar anchoring system and method are provided. The system includes: a rebar, with an external thread formed on the periphery of at least one end; an anchoring head, with a first perforation and a second perforation disposed respectively at both ends extending axially into the anchoring head and communicating with each other, the inner sides of the first and second perforations being formed respectively with a first internal thread matching with the external thread of the rebar and a second internal thread, and the anchoring head being mounted on the end of the rebar through the first internal thread and the external thread of the rebar; and a bolt, having a screw rod matching with the second internal thread, the screw rod being locked into the second perforation of the anchoring head, and the end of the screw rod pressing against the end of the rebar.

A hose connector 106 for a cartridge-operated fire extinguisher 100, the hose connector 106 including: a valve body connection tube 330 for connecting the hose connector 106 to a valve body of the fire extinguisher 100, the valve body connection tube 330 is non-threaded; a hose connection tube 332 for connecting a hose to the hose connector 106; and a fixing plate 334 for fixing the hose connector 106 to the valve body of the fire extinguisher 100.

A bushing assembly for tubular structures is disclosed. The bushing assembly includes a body having a substantially flat configuration and defining a planar surface and an outer edge; and a plurality of projections extending from the outer edge and traverse to the planar surface, each projection defining a longitudinal axis, each projection including at least one ridge extending at least partially along a surface of the projection and along the longitudinal axis.
