A module for the production of concrete parts has a row of displacement bodies that are adjacently arranged in a horizontal longitudinal direction (L) and that are clamped captively to a grid structure made of at least two individual grids running in the longitudinal direction (L). Surfaces of the grids are oriented in a transverse or inclined manner in relation to the horizontal. Each of the grids has at least a first and a second longitudinal bar arranged at a distance in parallel to one another and running in the longitudinal direction (L) and a plurality of transverse bars being arranged at a distance from one another and oriented in a transverse or inclined manner in relation to the horizontal. The transverse bars are respectively connected with the longitudinal bars. One of the displacement bodies for each grid has a first and a second retaining device.

A number of modular preformed skeletal steel panels are mounted side by side in a row on a building structure to form a composite panel assembly on the building structure. Each modular preformed skeletal steel panel comprises two mesh layers, namely a bottom mesh layer and a top mesh layer supported spaced-apart in parallel planes by intermediate spacers extending between the layers. The bottom layer has a plurality of spaced-apart outwardly projecting splice bars for interengagement with an adjacent preformed skeletal steel panel in the panel assembly thus facilitating interengagement of the modular preformed skeletal steel panels in the composite panel assembly. Each spacer comprises a cross member engaged with the top layer and having outwardly extending legs at opposite ends of the cross member. A lower end of each leg terminates in a foot which engages with the bottom layer. The cross member, legs and feet are all mutually perpendicular.

The invention relates to a reinforcing element (1) comprising a first (2) and a second reinforcing mat (3) having metal mat rods (6), which are welded at angles to each other at junction points (7), which reinforcing mats (2, 3) are held spaced apart from each other at a normal distance (9) by rod-shaped spacers (8) with respect to the first mat plane (4) and the second mat plane (5) of the reinforcing mats. The spacers are metal (8) and are permanently connected to individual mat rods (6) of the first (2) and second reinforcing mat (3) by welding connections (10), preferably resistance welding connections, wherein at least individual spacers (8) protrude outward at least beyond the first mat plane (4) of the first reinforcing mat (2) in a direction (11) pointing away from the second reinforcing mat (3) by a first protrusion length. The invention further relates to a double wall furnished with the reinforcing element and a method for producing the reinforcing element and the double wall.

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.

A multi-piece pre-assembled raft foundation is provided and includes pre-assemble bottom layer rebars of foundation slab, foundation steel columns, upper layer rebars of the foundation slab, and foundation rebars. The pre-assembled raft foundation is transported to a construction site for final assembly. A construction method of the multi-piece pre-assembled raft foundation is also provided.

The present invention relates to a prefabricated deck unit for a building system, the deck unit including: a reinforcing framework encased in a composite material, the reinforcing framework comprising: a first metal mesh unit, a plurality of interspaced spheroidal void formers attached to or in intimate contact with the first mesh unit, and a second mesh unit resting upon, or attached to, the spheroidal void formers, wherein the framework defines at least one terminal channel on at least one end of the deck unit, the terminal channel being shaped and dimensioned to snugly receive an elongate connecting rod for connecting the deck unit to a further structural element of the building system.

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.

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.
