FI96898C - Composite slab element - Google Patents

Abstract

A composite slab element comprised of a cast portion (1), e.g. concrete, cast reinforcement (2), e.g. a steel net, possible intermediate purlins (5) and joists (8). A single joist has at least two parallel ranged joist elements (8), between which a metal sheeting (4) is placed, whereat the edge of the metal sheeting extends from the joist element to the concrete and the metal sheeting functions both as a composite and a reinforcement part.

COMPOSITE SLAB ELEMENT

The invention relates to an industrially manufactured composite slab element, which consists of a specially constructed metal frame acting as a joint and / or reinforcing part, in which wooden planks are pressed on both sides, which together form a body part, a slab part, e.g. concrete, a tile part. steel mesh and intermediate ducks, eg wood / steel.

The elements are mainly used as detached houses, terraced houses, 10 low-rise buildings and the lower, intermediate and upper bases of shark structures. The element is very well suited when installed on the concrete side down. radonalapohjaksi.

* Load-bearing floor solutions manufactured by the prior art include concrete hollow and TT slabs and floor solutions made with various composite slab structures, for example Ad Publications Fi-66229, 60752.

1. Concrete-structured tiles very heavy, not 20 suitable for use in timber-framed buildings.

2. Transport and handling of concrete slabs due to weight is cumbersome and expensive.

3. Existing slab-based floor solutions va- *. mainly under site conditions, the parasites have to use either straight or profiled sheet metal as a casting base / mold.

2.

96898 4. The spans of current composite slab floor solutions are usually about 6 meters.

5. Body parts made entirely of wood to which joints have been attached for the casting compound. in 5 more cases it has to be rectified on site because the wood is twisting / twisting. A possible pre-increase must also be made on site.

6. When using the so-called. With the Homecon jointing method, the slab becomes heavy because the concrete in the profile slab does not work effectively and the thermal / sound insulation of the slab, HVAC piping and wall cladding are cumbersome / expensive.

The object of the invention is to eliminate the above-mentioned drawbacks and to produce a composite slab element in which a light and strong structure in which the wood / metal takes a traction is obtained as shown in Fig. 2 from wooden parts pressed on both sides of a specially constructed metal web and through the same part. - and concrete pu-20 cross-loading.

The tile element according to the invention is characterized mainly by the elements set out in claim 1.

The advantage of the invention is, above all, the considerable simplification of the manufacture compared with the prior art. Another advantage is that a significantly longer span is achieved as well as a lighter structure, which reduces the cost of moving and installing the element. A significant advantage is 3.

96898 also the space between the beams, which allows HVAC installations and adequate sound / thermal insulation between the floors. Transverse HVAC installations can be performed through the pre-formed openings (6) in the web. The advantage of 5 can also be considered the ease of making stairs and other openings and the lower surface of the beams, which acts as a collar and to which various roofing materials can be fastened directly by nailing. In addition, a significant advantage is also achieved in fire filtration, because the metal web, which acts as a connecting and reinforcing part 10, is located between the wood parts protecting the fire.

The making of balconies, bay windows and other projections is: very easy, at the passage the web is removed from a distance of about 50 mm to prevent a cold bridge.

In the following, the invention will be explained in detail with reference to the accompanying drawings.

Figure 1 shows an axonametric description of the element.

Figure 2 shows a cross section of the element.

Figure 3 shows a longitudinal section of the element.

Figure 4 shows the element inverted when used as the bottom of the radon, with pressure impregnated plank being used as the intermediate duck (5).

The flat tile element according to the figures is manufactured as follows: In the first step, the cut-to-size trees (3) and the metal web (4) are pressed together.

In the second stage, the beams are connected to a certain intermediate division and the intermediate grooves (5) are fixed in place.

In the third step, a layer about 50 mm thick is placed in a mold with a transferable edge at the casting edge (1) and vibrated evenly.

In the fourth step, a reinforcement (2) is installed on top of the casting compound.

In the fifth step, the assembled beam frame is mounted on the casting compound (1) and the reinforcement (2) with the intermediate dowel, the body part is vibrated and pressed into the concrete for mm until the web has sunk 25 mm and the intermediate grooves approx. 2-3 mm into the concrete. Support and allow to dry until the next day, lift up and take to interim storage.

The application examples presented above are not intended to limit the invention, but the invention can be modified completely freely within the scope of the claims. Examples include various materials as the frame structure, such as plastic, fiberglass and various plate structures, as well as the manufacture of the element without intermediate dowels.
