A prefabricated superimposed recycled lump concrete slab includes a fresh concrete, demolished concrete lumps, and a reinforcement fabric at a lower part of the slab. The demolished concrete lumps can protrude from the fresh concrete, but a protruding height is no more than 25 mm, and the protruding height is controlled by assembling molds. The assembling molds comprise casting molds and a height-controlling cover plate, reinforcement-locating slots are reserved on side molds of the casting molds, and a vertical position of the height-controlling is determined by using screws, position-controlling nuts and gaskets of different thicknesses, which are located at four corners of the casting molds. A construction method of the prefabricated superimposed recycled lump concrete slab is also provided.

The present invention relates to the construction industry, and in particular to laboratories, hospitals, food production areas and other places where asepsis is required. Specifically, it relates to a modular construction system based on self-supporting panels, which have post-formed exterior surfaces and are complemented with corner components of similar construction to build hermetic, waterproof and insulating walls that have smooth surfaces. For this, there is a modular system of panels for forming aseptic spaces within an enclosure and a method of installing a clean room wall by means of a modular system of panels to form aseptic spaces inside an enclosure.

A modular device adapted for subdividing room space, the modular device comprising: a panel comprising a corrugated portion positioned between a first planar surface and a second planar surface of the panel, wherein the peaks of the corrugated portion are in engagement with the first planar surface, wherein the troughs of the corrugated portion are in engagement with the second planar surface; the first planar surface and the second planar surface each having a first end and a second end; wherein the first and second ends of the first planar surface are respectively opposite relatively to the first and second ends of the second planar surface; the second planar surface is parallel to the first planar surface; wherein the corrugations are is parallel to the vertical axis of the panel; a concave female portion positioned along the vertical axis in the panel, wherein the concave female portion is formed from at least: the first end of the first planar surface, the first end of the second planar surface, and a curved portion from the corrugated portion; a convex male portion positioned along the vertical axis of the panel, wherein the convex male portion is positioned outside of the second end of the first planar surface and the second end of the second planar surface; wherein to extend the length of the panel, the convex male portion of a first panel is adapted to engage with the concave female portion of a second panel.

Approaches describe a panel system (e.g., a closed-, open-, and/or solid-panel system) that can be assembled quickly and easily in the field without field modifications to the panel. The panels can be precision engineered, and include a building connection system for structural and/or utility connection between building elements. An interpanel connector can include a structural connector, a utility connector, or a combination connector that is both a structural and utility connector. A control component or another appropriate component can be used to automatically facilitate coupling of one or more building elements, and provide feedback on the assembly process.

Modular building methods and systems using lightweight modular panels, and specially configured transition panels for transitioning from wall to floor, or from wall to roof. Identically configured standard panels are used for constructing the walls, floor, and roof, with transitions from one structure to the next (e.g., wall to floor, or wall to roof). Each of the variously configured panel types includes channels (e.g., 2 pair of channels) formed through the length of the foam body, where the channels are configured to receive splines (e.g., flanges of an I-beam) therein. In the standard panel, the channels may include pairs of top and bottom channels, with the channels offset towards the respective panel major faces. In the transition panels, the channels may be similarly configured, but positioned differently to make the appropriate transition. The splines are connected to a frame, which acts as a template and transfers loads to a foundation.

A lumber use designation system includes a building construction plan that shows the layout, wall thickness, wall height, ceiling angles, etc., of a structure, which are color coded from a series of color codes each corresponding to a preselected, standard board size and length of lumber that should be selected for constructing a particular portion of the structure. The system includes a supply of lumber boards marked with a color code correlating to the color code found on the construction plans. The lumber boards may be imprinted by an ink spray head. A method of installing lumber during the construction of a structure is disclosed.

An interchangeable structure module to provide a structural building panel may include a structural panel having a front surface being opposed to a back surface and having side surfaces to connect the front surface and the back surface and having a top surface and a bottom surface to connect the front surface and the back surface; and a structural stud to engage the structural panel. The structural stud is U-shaped.

Various embodiments for a wall assembly having an acoustic panel defining a plurality of thru-holes that act to break low density mechanically coupled pathways for sound transmission through the acoustic panel for reducing sound transmission are disclosed herein.

A modular seamless corner component for providing a corner to a structure without having to compromise between structural integrity and energy efficiency. The continuous insulation and structure of the modular seamless corner component provide for a stronger corner because there are no seams to magnify stress and provide for a high energy efficiency because there is no thermal bridging.

A medical-gas panel connector system includes a frame assembly. The frame assembly includes a horizontal frame member, a vertical frame member connected to the horizontal frame member, and a ceiling integration assembly. The medical-gas panel connector system also includes a medical-gas outlet removably secured to at least one of the horizontal frame member and the vertical frame member via a bracket. In addition, a manifold is removably secured to the ceiling integration assembly, the manifold being at least partially disposed inside the medical-gas panel connector system, and a flexible gas line connects the manifold to the medical-gas outlet. The medical-gas panel connector can be reconfigured and rearranged within a modular wall system.
