A reinforcement arrangement and a method for producing a construction material body using the reinforcement arrangement. The reinforcement arrangement comprises a reinforcement body and at least one holding anchor unit. Each holding anchor unit is arranged or attached at the reinforcement body by a foot section. A holding section adjoining the foot section is moveable between a storage position and a function position. In the storage position, the holding section extends directly adjacent along the reinforcement body and abuts the reinforcement body at one or more locations. In the function position, a free end of the holding section opposite the foot section is larger than in the storage position. The holding section can be moved manually or self-acting from the storage position into the function position. The reinforcement body, the holding section, and the foot section are preferably embodied as textile-reinforced elements.

A system for providing reinforcement to structures comprises a prefabricated rebar assembly, a first end plate and a second end plate. The prefabricated rebar assembly comprises multiple rods connected to each other. The prefabricated rebar assembly is held between the first end plate and the second end plate to form a block of rebar assembly.

Provided is a novel metallic coarse aggregate for concrete which can be used as a coarse aggregate which is one of the essential constituents of concrete, can further improve the compressive strength and tensile strength of concrete, is less likely to be sedimented in fresh concrete, and has good productivity at a low cost. The metallic coarse aggregate for concrete includes a coarse aggregate body including a spherical cap portion bonded body having two hollow spherical cap portions and an annular portion protruding from a surface of the spherical cap portion bonded body so as to surround an outer periphery of the spherical cap portion bonded body, the annular portion having a shape in which a corner of a rectangular shape is bent upward or downward.

A prong is configured for use with a concrete reinforcement element and includes first and second legs positioned opposite first and second sides of the prong and a bridge portion connecting distal ends the legs, where the bridge portion forms a first end of the prong. The legs extend from the bridge portion to a second end of the prong opposite the first end, and each of the legs has a proximal end at the second end of the prong. The proximal end of the first leg is bent toward the second leg, and the proximal end of the second leg is bent toward the first leg, such that the proximal ends of the legs overlap each other. Inner surfaces of the proximal ends of the legs define engagement surfaces configured to engage a tie wire, enabling the proximal ends to be connected to the tie wire.

The invention relates to a system for erecting a building structure, the system comprising a foundation for receiving the building structure, and a plurality of inner and outer walls, roof and floor panels, the panels being adapted to engage each other for defining at least one story of the building structure, wherein the foundation comprises a first section and a second section, the first section being adapted to bear the load of the building structure and the second section being adapted to provide access to the interiors of the building structure.

Reinforcing panel having high durability, high strength, and high hardness is applied such that a concrete structure may be repaired to have excellent resistance to an external environment and to be structurally excellent. In comparison to existing bonding methods, a concrete structure and a reinforcing panel may be completely attached to each other as a whole using a repairing material with high fluidity as a cement-based material injected into a repair cross section. Part with microcracks is completely filled with repairing cement mortar injected at high pressure. Since reinforcing panel is precast-fabricated in a factory, embossing, intaglio, color, and the like may be easily added to an external surface of the reinforcing panel and an excellent exterior may be provided after repair due to an aesthetic cross section thereof. The reinforcing panel fabricated in a factory is applied as to reduce labor costs and construction costs.

Provided are a method of manufacturing a three-dimensional textile reinforcement material and a method of constructing a textile reinforced concrete structure using a three-dimensional textile reinforcement material. A two-dimensional grid is bent into a three-dimensional shape using a two-dimensionally woven or knitted textile grid, and the bent grid is coupled with at least one two-dimensional grid, and thus the three-dimensional textile reinforcement material can be simply and easily formed. The three-dimensional textile reinforcement material can be formed by coating the coupled two-dimensional grid and a three-dimensional grid with a thermosetting resin and curing the coupled grids to support a concrete pouring pressure. The three-dimensional textile reinforcement material is formed in a truss material, and the three-dimensional textile reinforcement material with high bending strength can be manufactured, thus a concrete pouring pressure can be supported when a textile reinforced concrete structure is constructed using the three-dimensional textile reinforcement material.

A reinforcement arrangement and a method for producing a construction material body using the reinforcement arrangement. The reinforcement arrangement comprises a reinforcement body and at least one holding anchor unit. Each holding anchor unit is arranged or attached at the reinforcement body by a foot section. A holding section adjoining the foot section is moveable between a storage position and a function position. In the storage position, the holding section extends directly adjacent along the reinforcement body and abuts the reinforcement body at one or more locations. In the function position, a free end of the holding section opposite the foot section is larger than in the storage position. The holding section can be moved manually or self-acting from the storage position into the function position. The reinforcement body, the holding section, and the foot section are preferably embodied as textile-reinforced elements.

Stay-in-place forms and methods and equipment for installing thereof. A concrete form includes a vertical component and a horizontal component, the vertical component located substantially perpendicular to the horizontal component. Also, the form includes an interior surface, at least a portion of the interior surface providing a form for supporting uncured concrete; wherein the uncured concrete forms a concrete structural portion upon curing of the uncured concrete; and wherein the interior surface remains attached to the concrete structural portion after curing. The form may include inserts and compatible form attachments. Also, forms including recesses may be utilized to reduce the weight thereof. Lifting equipment and accessories may be utilized to lift the form from a form holder and set same in place. Forms contain the work area as soon as it is installed to minimize fall hazards and the time, costs, and downtime associated with installation of safety measures.

A structural panel for building construction includes a series of truss members, and accompanying sinusoidal support elements in welded communication and enclosed in a planarly extended foam layer. Together, the structural panel allows for easy and efficient off-site assembly, which creates a lightweight panel with an increased weight-bearing capacity using inexpensive and versatile materials.
