Composite precast concrete panels are described herein having have an anchor that distributes forces imposed on the anchor through concrete wythes of the panels. Specifically, pins can be embedded in at least one concrete wythe, and then the anchor is secured to the wythe as described herein. The anchor extends through another Wythe to selectively connect to a hoist system that moves and places the composite precast concrete panel. The forces imposed on the anchor are distributed through the pins and into multiple concrete wythes to prevent failure of the composite precast concrete panels and improve safety.

A concrete wall section manufactured with a weight that allows the user of the concrete wall section to transport manually the concrete wall section. Combinations of concrete wall sections can be used to replace traditional frames of a structure.

Improved tilt-up and precast construction panels and improved methods for creating the same address deficiencies in the current tilt-up and precast construction panels. Improved tilt-up and precast construction panels use less concrete and less steel reinforcement and weigh less than current tilt-up and precast construction panels. Additionally, improved tilt-up and precast construction panels have greater insulative properties (both heat and sound) than do current tilt-up and precast construction panels. Improved tilt-up and precast construction panels require less labor on the construction site, thereby increasing efficiency and profitability of construction crews. Additional advantages of implementations of the invention will become apparent through the following description and by practice of implementations of the invention.

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 structural insulation panel (SIP) is made of a central insulation material or block core covered with cementitious material. The layers of cementitious material are reinforced with fiber mesh sheets, rebar and corner blocks. The corner blocks are held in thickened cementitious material edges by reinforcement pins that are fixed to the corner blocks. The corner blocks are accessible for lifting the panel and for assembling multiple panels to build a wall.

A shear connector for use with insulated concrete panels. The shear connector comprises an elongated core member that includes a first end and a second end, and a flanged end-piece removably secured to one of the first end or the second end of the core member. At least a portion of the flanged end-piece includes a maximum diameter that is larger than a maximum diameter of the core member. The shear connector is configured to transfer shear forces.

Disclosed is a building board construction that provides enhanced acoustical properties. In one possible embodiment, the board is a gypsum board with opposing facing sheets and an intermediate set gypsum core. An opened celled polymeric sheet is formed within the gypsum core and gives the resulting board enhanced sound absorption. In an alternative embodiment, individual pieces of polymeric foam are used in stead of the polymeric sheet. Also disclosed are various manufacturing methods whereby boards with enhanced acoustical properties can be formed in an continuous process. The various components of the present disclosure, and the manner in which they interrelate, are described in greater detail hereinafter.

The present invention discloses a prefabricated module, including a bottom plate, a left side plate, a top plate, and a right side plate. The bottom plate, the left side plate, the top plate, and the right side plate are connected in sequence to form a closed loop. Filling internal molds are provided inside the bottom plate, the left side plate, the top plate and the right side plate. The filling internal molds are provided with a plurality of through holes. Tensile members are further provided inside the prefabricated module, the tensile members are continuously distributed inside the bottom plate, the left side plate, the top plate and the right side plate, and the tensile members are connected end to end. The filling internal molds and the tensile members are encapsulated inside an inorganic composite material. The structure of the prefabricated module can improve the strength and reduce the weight.

Reinforced concrete structures and assemblies, building systems, and methods of fabrication.

A structural insulated building unit is provided for constructing a building. The structural insulated building unit includes an insulating core, first and second cementitious panels, and a connecting portion. The insulating core is defined by multiple sides and opposing first and second faces. The first and second cementitious panels are coupled to the first and second faces of the insulating core. The connecting portion is provided on one of the sides of the insulating core, and aligns the structural insulated building unit with an adjacent structural insulated building unit having a complementary connecting portion when constructing a building.
