A precast building material contains: a substrate, a peripheral frame, a metal reinforcement unit, and a concrete layer. The substrate is in a parallelogram shape. The peripheral frame is mounted around the substrate so that an accommodation chamber is defined between the peripheral frame and the substrate. The peripheral frame includes multiple first connection rails having at least one first slot, multiple second connection rails having at least one second slot, multiple convex engagement portions, and multiple concave engagement portions. The respective first connection rail has multiple first locking orifices, and the respective second connection rail has multiple second locking orifices. The metal reinforcement unit is fixed in the accommodation chamber and includes multiple rebars. The concrete layer is filled with the accommodation chamber, and the concrete layer is connected with the peripheral frame and the metal reinforcement unit and is removable from the substrate.

Provided herewith is a system for assembling a temporary structure using a plurality of separate members. A first member has ends at opposite sides of an elongated body portion, with notches on the top and bottom sides of each end. A second member has ends with notches formed on opposite between the ends. These notches enable the first and second members to engage with other such separate members. A third member has a triangular shape that functions as a roof truss with opposing sloped surfaces and an underside. A pair of truss notches is formed at positions corresponding to the notches of the first member, for each engaging with one of the plurality of separate members. The third member also includes feature hooks, formed on the sloped surfaces, for engaging with a fourth member defined by a planar roofing material having a plurality of holes.

Structural Panel Chase Connection Manufacture Methods are the embedded frame solution to the problems associated with providing access for services, such as plumbing or electrical chases with high precision and accuracy. Connecting two or more panels in any direction using the embedded frame method becomes easy yet incredibly strong without requiring special tools for assembly or disassembly, so that components can be flat packed and stored when not in use.

Flexible and variable these Structural Panel Chase Connection Manufacture Methods can accommodate a wide variety of dimensional configuration, not limited to only panel, post and beam configurations and can be manufactured using any available flat building materials.

A retention housing for receiving at least one load transfer member is provided. In some embodiments, the retention housing and load transfer member may be included in a sandwich wall panel or a double wall panel. The load transfer member may transfer loads between first and second concrete elements. The retention housing may include first and second retention members, at least one guide member, and a size indicator for aligning the retention members with respect to each other. The guide member may retain the load transfer member at a predetermined angle. In some embodiments, the size indicator may correspond to the thickness of an insulation layer, such as in a sandwich wall panel. The retention housing may further include at least one depth locating means. A retention housing including first and second retention members may further include means for connecting the first and second retention members, such as in an aligned position.

A system and method for attaching precast panels and for coupling a plurality of reinforcing bars together. The system and method have a plurality of reinforcing bar coupler assemblies as shown to mechanically splice reinforcing bars of two precast panels or a plurality of reinforcing bars together to provide a permanent means of connecting the panels. Each of the reinforcing bar coupler assemblies have a first component, clamp ring, insert and second component and spring that are assembled and used to couple a plurality of reinforcing bars together. The reinforcing bar coupler assembly is precast into precast panels that are then adapted to be mounted and coupled together using the reinforcing bar coupler assemblies.

A modular wall system for use in trade shows includes a wall or header panel formed of frame parts, and a connecting bracket for detachably connecting the end of the panel to an upstanding column. Perpendicular sections of a corner connector are received in the hollow end of different ones of the frame parts to connect the frame parts. A fabric cover defines a recess with an open end adapted to receive the frame parts. A closure device is provided for at least partially closing the open end of the fabric cover. A vertical support member extends from the frame parts to a surface to transmit the weight of an accessory to the surface. The accessory may be an adjustable garment rack, a coupling grid, a shelving unit, or a peg-board unit and a hook. The system includes a crate adapted to receive a plurality of members for transport.

A process for fabricating a unitized structure comprises creating a multilayer structure by applying a flame-retardant resin to a first layer and stacking, on the first layer, an intermediate layer comprising a honeycomb structure. Further, a second layer is stacked on the intermediate layer and the flame-retardant resin is applied to the second layer. The multilayer structure is then heated to a desired temperature and a pressure is applied about the multilayer structure for a predetermined process time. Moreover, the flame-retardant resin is prevented from entering spaces of the honeycomb structure. After elapse of the predetermined process time, the pressure is released, creating the unitized structure.

A panel is disclosed for use in insulating an edifice that includes a first pane, a second pane in engagement with the first pane so as to define a channel there between configured and dimensioned for drainage and air flow, a clip in engagement with the first and second panes, and an insulator including an upper portion that is positioned within the clip. A system for use in insulating an edifice includes identical panels, wherein the insulator of one panel is positionable within the clip of another panel to connect the panels together. A panel clip for use in insulating an edifice includes a first arm defining an outer surface with a plurality of connectors, a saddle extending from the first arm, and a second arm connected to the saddle opposite the first arm such that the clip is generally H-shaped in configuration.

A retention housing for receiving at least one load transfer member is provided. In some embodiments, the retention housing and load transfer member may be included in a sandwich wall panel or a double wall panel.
