Description

Technical field

The technical solution relates to the construction of a sandwich sandwich ribbing, intended especially for the construction of houses.

Background Art

For the building envelope, reinforced concrete sandwich panels are used, which have the function of supporting, covering and thermal insulation. A layer of heat-insulating material is arranged between the inner and outer reinforced concrete slab, the so-called monier. for example polystyrene or mineral fibers. Both monitors are connected to each other by steel ladders or mandrels, which are generally protected from corrosion by concrete encasement in a suitable geometric configuration, for example in the ribs of the panel. The disadvantages of the existing sandwich circuit elements are mainly the high weight C if their construction? they are free of reinforcing ribs that lighten their profile) and consequently deteriorate handling and furthermore in an inadequate amount of thermal resistance, which necessitates the additional pre-casting of the insulating layers with the surface treatment. Relatively large thickness of the outer monrier, up to d cm. it adversely affects the magnitude of internal forces caused by temperature changes and thus reinforcement requirements. In commonly used reinforcement, thermal stress causes cracks to develop and widen, which adversely affect the watertightness and appearance of the peripheral components. The connection with reinforced ribs or concrete targets then creates flail bridges and deteriorates the expansion joint.

-2ber parts are provided with an inserted transverse layer of additional thermal insulation. The additional heat insulation is preferably arranged throughout the cross-section of the ribs which are interrupted in their interface with the outer monier. The additional thermal insulation passes through the steel ladders of the reinforcement with the anchors of the outer monier and the inner monier of the panel, which are arranged at least in some transverse reinforcing ribs.

The sandwich peripheral panels of this invention have significantly improved thermal properties with respect to the thermal bridges in the joints between the inner and outer monitors.

The technical solution will be explained in more detail by means of a drawing which shows an axonometric plunging on a construction sandwich ribbed circuit board (with the indicated inlet opening) and a horizontal section A-A of the part of the panel.

An example of a technical solution

The peripheral panel is a 250 mm thick sandwich type, where a layer of thermal insulation, for example polystyrene, of thickness 160 mm is between the reinforced outer moni y thickness and the reinforced inner wall thickness of 40 mm. The monier, i.e. the outer monier 9 and the inner monier 10, are provided with a steel reinforcement 13 and are connected by internal reinforcing ribs 11 to the reinforcement 13 and the outer ribs 12.

The reinforcement 1.3 is in both monitors 9, 10 formed by steel nets and in the ribs 11, 12 by a steel lattice, for example ladders. The outer ribs 12 are provided with a circumferential groove. The inner stiffening ribs 11 and the outer ribs 12 are provided with an intermediate transverse layer of 25 mm thick thermal insulation made of pulystyrene, arranged over the entire cross-section of the ribs 11, 12. The inner stiffening ribs 11 and the circumferential rib 12 are interrupted by the contact areas with the outer pointer 9. Tin is severely disrupted by the thermal ripples between the sandwiches and the sandwiches 1 to 3 of the steel. the reinforcement bars 121 with the anchors of the outer monier 9 and the inner monier 10. In addition, the layered anchors may extend (not shown) at the locations of the component with the increased load of the peripheral panel. inner no The structural sandwich ribbed component according to the technical solution can be used especially for the construction of family houses.
