A forming system includes a frame and two forming walls. The two forming walls are positioned at a distance from each other to define a first vertical wall course. One forming wall is supported by the frame such that the one forming wall can be translated toward or away from the respective other forming wall. The frame can be raised to raise the two forming walls to be positioned to pour a second vertical course on top of the first vertical course. The translation of the one forming wall allows for the pouring of the first vertical course with horizontally extending rebar that extends through the one forming wall outside of the first vertical wall course, to tie in to a subsequently poured floor slab. The translation permits the vertical raising of the one forming wall, without striking the extending rebar, to pour the second vertical course on the first vertical course. A worker's platform is provided that is supported by the frame and vertically movable by raising the frame. The worker's platform is located below the one forming wall on a side of the one forming wall opposite the respective other forming wall and is rollable or pivotal to also clear the extending rebar during raising of the frame.

The disclosed building construction system with split precast horizontal floor supports combines the strength and ease of construction of pre-cast concrete, with ease of transportation of cast-in-place concrete. The system avoids the requirement of casting difficult shapes by breaking the complex T-shape sections of prior patents into separate flat pieces. The formwork for flat pieces is simpler than that of complex items that include both long and wide components. For examine, T-shapes and cross-shapes are hard to cast and difficult to transport because these shapes do not sit flat, and thus must be supported at their ends. Instead of this complex casting and transport, the slabs are separated into shapes that can later be placed around the columns. This simulates the strength of a fully-precast system, while reducing the precast costs and transportation costs.

The profiled metal fibre with a substantially rectangular cross-section, also with bent fibre ends in the form of a clip, is used to stabilise, bond, attach or join materials and construction materials such as concrete, wood, paper and the like. The fibre edges of the fibre outer surfaces extending in the longitudinal direction of the fibre are designed as edge surfaces (2) oriented at an angle to the fibre outer surfaces in the manner of a bevel. The two wider fibre outer surfaces (3.1, 3.2) of the rectangular fibre are provided with V-shaped channels (4) extending in the longitudinal direction, wherein the edge surfaces (2) are provided with projections (6) and the V-shaped channels (4) are provided with end zones (5) that bound their longitudinal extent. The projections form anchoring heads and the end zones form anchor surfaces with respect to the material to be stabilised, bonded or attached.

A panel assembly for a building includes a panel configured to extend between a first surface and a second surface. The panel is movable along a predetermined path relative to the first surface and the second surface. A first pin and a second pin are coupled to the panel. A first bottom face plate is positioned on a first side and defines a first slot. A second bottom face plate is positioned on a second side and defines a second slot. A first top face plate is positioned on the first side and defines a third slot. A second top face plate is positioned on the second side and defines a fourth slot. The first pin is movable in the first slot and the second slot, and the second pin is movable in the third slot and the fourth slot for guiding movement of the panel along the predetermined path.

A V-shaped tie hoop assembly enhances field construction performance by integrally forming a plurality of V-shaped tie hoops after constituting the plurality of V-shaped tie hoops in a bundle form, maintains intervals, and enhances reinforcement performance. The V-shaped tie hoop assembly can includes: a plurality of V-shaped tie hoops, each of which has a bending part at the center thereof and anchor parts extending to opposite sides of the bending part, and disposed at different heights at an interval; and a vertical support bar connecting all of the V-shaped tie hoops to integrally couple the V-shaped tie hoops.

The hybrid post-installed anchor for concrete is a structural anchor for installation within a hole formed in concrete. The hybrid post-installed anchor for concrete includes an anchor rod and a plurality of anchor rings mounted on and encircling the anchor rod. Each anchor ring includes a cylindrical ring, having opposed open upper and lower ends, and a plurality of fins secured to an outer surface of the cylindrical ring. Each fin has a fixed edge, which is secured to the outer surface of the cylindrical ring, and a free edge. Each fin projects radially and upwardly, such that each fin is angled with respect to a common central axis of the anchor rod and each anchor ring when the anchor rings are mounted coaxially on the anchor rod. Alternatively, the fins may be formed integrally on the anchor rod, without separate cylindrical rings.

The invention can be used in producing prestressed reinforcement for reinforcing items made of concrete and provides maximally strong adhesion to concrete in any potentially possible direction of displacement, and a high level of specific strength, relaxation resistance and fatigue resistance. In a reinforcement wire having a spiral profile, three ruled surfaces, separated from one another by the areas of the cylindrical surface, are applied on the surface of the wire along a spiral line. Trapezoidal projections are disposed on the ruled surfaces at an incline in a direction reversed to the direction of the spiral line along which the ruled surfaces themselves are arranged.
