A connector assembly for structural members includes a support plate that has a primary portion and a first tab portion extending from the primary portion. A second tab portion also extends from the primary portion, and the primary portion defines at least one through hole that is configured to receive a fastener. A first stirrup plate defines a first slot that is configured to receive the first tab portion such that the first stirrup plate extends from the support plate in a first direction. The first stirrup plate further defines at least one through hole that is configured to receive a fastener. A second stirrup plate defines a second slot that is configured to receive the second tab portion such that the second stirrup plate extends from the support plate in a second direction opposite the first direction.

Apparatus and methods for joining tubes in transport structures are presented herein. A part having an attached node with a socket can be joined with tubes. The tubes can be placed along nonparallel axes within the socket; and a wedge can be used to secure the tubes to the socket. The wedge can be secured between the tubes by using a fastener, such as a blind fastener; alternatively, or additionally, the wedge can be secured between the tubes using an adhesive.

A first beam (1) is inserted through a transverse opening (4) in a tubular second beam (2). A bolt (7) is inserted through unthreaded holes (9A, 9B) in the second beam. The bolt may be transverse to both beams. A wedge (5) is threaded onto the bolt inside the second beam (2). Tightening the bolt moves the wedge against a side of the first beam, forcing it against surfaces (11, 12, 13) of the transverse opening (4) opposite the wedge. The bolt counters the reaction to this force. The beams can be formed as extrusions. The joint only requires machining for the transverse opening (4) and smoothbore bolt holes (9A, 9B) for a single bolt. The second beam may have a rectangular cross section with relatively thicker corners (2A-2D) and thinner mid-walls (2E-2H).

A hold-down clamp for holding a cable tray on a strut channel includes a main body member extending between first and second ends, opposed side walls extending downwardly and perpendicularly from the main body member, and first and second side members extending from each of the opposed side walls. The main body member has a first end defining a clamp engagement portion and a second end defining an expansion guide portion. Each of the first and second side members includes a flange having a clamp engagement structure, a planar middle structure, and an expansion guide structure that are integrally connected to each other, and a clamping tooth, which is defined between the clamp engagement structure of the flange and the side wall such that the clamping tooth transitions into the clamp engagement structure of the flange and the side wall of the hold-down clamp.

The angle connector (100) has two free ends (110, 120) aligned perpendicular to each other, for the purpose of being inserted into an associated cavity of a supporting profile (10, 20), such that at every free end (110, 120) of the angle connector, a passive means of fixation (131, 132, 133) is provided, via which from one outer side of the supporting profile (10, 20), the respective end of the angle connector can he detachably connected to the associated supporting profile by way of a complementary active fixation element (40, 44). Between the free ends that are aligned perpendicular to each other, a corner element is provided, with profile elements (111, 112) compatible with the supporting profiles provided on its two outer sides that are positioned perpendicular to each other, respectively reaching until the height of the associated surface (55) of the corner element (110).

The present invention provides modular frame assembly including a plurality of connecting pieces. The connecting pieces can include a first plurality of coupling connectors, a second plurality of tee connectors, a third plurality of corner connectors, and a fourth plurality of elongate members. Each of the plurality of connecting pieces is adapted to receive at least two elongate members such that a rectangular structure can be constructed from the plurality of connecting pieces.

A removable bracket includes a generally planar body having a front face, a rear face, a first longitudinal side, a second longitudinal side, a first lateral side, and a second lateral side. Each of the first lateral side and the second lateral side extends between the first longitudinal side and the second longitudinal side and includes a lip extending outwardly from the front face. A lateral axis bisects the body and a longitudinal axis bisects the body. The body is symmetrical about each of the lateral and longitudinal axes. Two supports extending generally perpendicularly outwardly from the front face proximate to and on either side of the lateral axis. A kit includes a plurality of the brackets, and at least one of a rod, a first shelf, a plurality of extension pieces, and a second shelf.

Disclosed is a rail fixing assembly, configured to fix a rail formed by connecting rail blocks, and including a base, pressing blocks, a movable clamping block and a fixing part; an installation groove is formed in the base, the pressing block is disposed above the base, an installation hole is formed in the pressing block, the lower end of the movable clamping block is inserted into the installation groove after passing through the installation hole and may move or rotate in the installation groove; the rail block is installed at the upper end of the movable clamping block, the movable clamping block moves or rotates in the installation groove to realize displacement or angle adjustment, the side wall of the rail block abuts against the pressing block. The application is convenient for fine adjustment during rail installation, so as to enable the installation more convenient and improve the installation efficiency.

A tonneau cover and a method of attachment are disclosed herein. In some embodiments, a self-energizing clamp can be used to retain a tonneau cover onto a side wall of a truck bed, or other vehicle bed. In some embodiments, the clamp can be rotated between a usage position and a storage position in order to prevent the clamp from incidental movement or harm while accessing the truck bed.

A grating for use as shelves for pallet racks or heavy-duty racks, having two longitudinal sides and cross members fitted between the longitudinal sides. The, longitudinal sides are in the shape of a profile in cross section. The profile includes at least a first leg and a second leg arranged substantially orthogonal to the first leg. At least two of the cross members have an open profile, in particular a U- or L-shaped profile in cross section, the open end of which is oriented towards the underside of the grating. Each of these cross members has at least two punched recesses at each end. The first leg of the profile is arranged in each punched recess and is firmly connected thereto via a form- or force-fitting connection method. The first leg of the profile has at least one deformation.
