CONSTRUCTION OF LARGE-SPAN SELF-BRAND BUILDINGS OF COMPOSITE LOAD-BEARING WALL PANELS AND FLOORS

摘要

The present invention relates to a composite wall panel and to a construction using such panels. The wall panel (1) comprises two slabs (2, 3) made of reinforced concrete, fixed to each other by some spacing elements thereby forming a free space between them which is partially filled with a thermal insulation (10) adhering to the inner surface of one of the concrete slabs (2, 3), the rest of the space being used as an air ventilation (11), characterized by the fact that each slab (2, 3) is reinforced with two wire nettings (5), the slabs (2, 3) being maintained at a given distance by means of some steel strips (4) fixed in a continuous manner on the entire length of the wall panel (1), anchored to the two slabs (2, 3) by means of some steel loops (7) having some holes (9) into which short steel rod anchors (8) are inserted keeping the distance between the two nettings (5) and supporting some additional longitudinal reinforcing bars (6) or prestressed cables, respectively.
