A self-bracing, two-way moment frame precast system for industrial support structure and method of erecting a precast industrial support structure without temporary or permanent bracing or shoring are disclosed. This is accomplished by utilizing a moment frame element in two directions to create free standing tower that requires no bracing during erection or in service. The system also utilizes a connection that allows the erection crane to achieve alignment during erection such that the entire system can be erected by a ground based personnel.

A support assembly for providing a high degree of lateral strength and integrity is presented herein. The support assembly includes a beam support bracket having a body and at least one elongated support member that is slidingly engaged with a corresponding lateral beam. The elongated support member of the beam support bracket is defined by spaced apart first and second support plates each including oppositely disposed edges which will mate with corresponding ledges, protrusions or reinforced corners within the lateral beam and bracket body.

A modular structure system of detachable members, the system includes a support pillar and various connectors. The support pillar has a main body and a plurality of channel walls outwardly radiating from an outside surface of the main body. The channel walls are disposed lengthwise on the main body from one terminal end of the main body to another terminal end of the main body. The support pillar has a symmetrical cross-sectional shape and each of the channel walls has an expanded distal end forming two lips.

This invention provides connector assemblies comprising at least two connector elements pivotally joined to each other, wherein each connector element is configured for attachment to a natural tree pole such as bamboo. Useful connector elements include members configured to conform the surface of a natural tree pole. Useful connector elements include terminal connector elements configured for attachment to the terminal end of a natural tree pole and side connector elements configured for attachment to the side of a natural tree pole.

A machining method and coupling structure for a fiber reinforced plastic structure member (1) obtained by narrowing an end of the member (1). Also included are a reinforcing member (4) which inhibits expansion by adhering to the outer circumference of the narrowed portion of the fiber reinforced plastic structure member, a locking member (2) which is provided with a through-hole (2a) in an axial direction and which fits into a narrowed portion (1a) of the fiber reinforced plastic structure member 1, a coupling anchoring member (3) which is provided with a rotation stop on the side thereof, and a spacer (5) which restricts only a rotation of the coupling anchoring member (3) and which is attached between a member (7) to be coupled and an end of the fiber reinforced plastic structure member (1) by passing the coupling anchoring member (3) through so as to slide in the axial direction.

A method for using modular items arranged as a system to connect easily available mostly inexpensive, bulky materials sourced elsewhere for the purpose of constructing objects of a person's own or another's design. The modular items work as an interlocking system that allows a wide range of options for securely connecting hoses, timber, pipes, plastic, metal and plywood sheets together as well as allowing various degrees of freedom of movement where required. Among other methods, connectors comprised of specialized sections that connect with each other as well as various base sections via inserts, lugs or other means are used to quickly assemble a designed item.

An inflatable greenhouse panel joiner includes a middle circular tube, a first circular tube, and a second circular tube. Each tube includes an input base and an output base for the user to introduce supporting materials. The first circular tube and the second circular tube both include a pair of filleted edges for the user to slide the panel into the first or second circular tube, respectively. The panel joiner allows the user to join multiple plastic panels with support material to build or modify a greenhouse with minimum effort.

A joint assembly comprising; an engagement block having a plurality of insert receiving faces; each insert receiving face having a slot, and an aperture at a mid-point of said slot; a plurality of inserts each having a core, at least a pair of ribs projecting from said core, a coupling at an insertion end of the core and a mount at a mounting end of the core, and; a coupling pin; wherein said engagement block is arranged to receive the inserts, with said ribs received into the slots and said core received into said aperture, said coupling pin arranged to be inserted into said engagement block and couple with the couplings of said inserts so as to releasably fix the inserts to the engagement block.

A tube construction set. The tube construction set includes a set of tubes. Each tube includes a wall, where the wall is the body of the tube, a first end and a second end, where the second end is opposite the first end. Each tube also includes four holes near the first end of tube and four holes near the second end of the tube. The tube construction set also includes a set of connectors. Each connector is configured to attach two or more tubes to one another and includes a first port, where the first port is configured to receive a first tube a second port, where the second port is configured to receive a second tube. Each connector also includes a first hole near the first port and a second hole near the second port.

A module splicing structure comprises to-be-spliced modules (C), a connecting component (A), a reinforcing accessory (B), and functional accessories (D, E, G). The to-be-spliced modules (C) are provided with holes or troughs. The connecting component (A) is inserted into the holes or the troughs of two adjacent to-be-spliced modules (C). The shape of the whole or partial cross section of the connecting component (A) inserted into the to-be-spliced modules (C) is the same as the shape of the cross sections of the holes or the troughs of the to-be-spliced modules (C). Connected by the connecting component (A), multiple to-be-spliced modules (C) are spliced into a whole structure or a building. The structure is applied to the field of engineering construction, and can be assembled, disassembled and maintained conveniently and quickly.
