摘要:
The invention relates to a steel beam (1) for supporting floor plates (2), consisting of a bottom plate (4) and a beam part (5). In the beam (1) and onto bottom plate (4), one or more profiles (7) are mounted, extending in a longitudinal direction, via which electric wiring liquids or gasses may be distributed. A connection can be made by drilling a hole in the profile via the bottom plate.
摘要:
The invention relates to a method for pouring a structural floor, in the process of which hollowcore concrete slabs (3) are placed at least substantially united onto beams (1), after which the space between the hollowcore concrete slabs (3) is filled with a mortar. Before pouring, strips (5) made of a flexible material are placed in a number of selected spaces between the hollowcore concrete slabs (3).
摘要:
The invention relates to a beam (1) for supporting floor elements (2), having a bottom side, a top side and two lateral sides. The inventive beam (1) consists of a bottom plate (8) and two separate, identical combined plates (10a,10b), each of which is folded in a longitudinal direction so as to form a lateral side and half the top side of the beam. Preferably, two edges (9a,9b) of the bottom plate (8) are folded in such a way that two re-entrant angles are formed into which the combined plates(10a,10b) may be fitted.
摘要:
The invention relates to a prefabricated beam (1) for supporting floor plates (2), like hollowcore plates or precast reinforced concrete plates. The beam (1) consists of a beam part (5) having a trapezoidal or triangular cross section and a rectangular bottom part (4), while the width of the beam part (5) and the width of the bottom part (4) are at least substantially the same. For pouring a structural floor, the floor plates (2) are placed between the beams (1) and separately supported.
摘要:
The invention relates to a method for reinforcing a steel beam (1). For that purpose, a number of prestress wires (8) or strands of prestress wires is stretched parallel to a bottom plate (4) of the beam (1), after which the bottom plate (4) is covered with liquid concrete (9) or epoxybound concrete, in such a way that the prestress wires (8) or strands of prestress wires are completely embedded. Subsequently the concrete (9) or epoxybound concrete is cured, after which the prestress wires (8) are cut off near the ends of the steel beam (1).
