Abstract

The floor slab consists of at least one segment (1,2) as a double wall element, and the intermediate space (15) between the double walls and one or more sidewall elements in the join is uniformly filled with concrete. The double wall elements of the floor slab segments and sidewall segments (3) consist of a larger slab (4) for the outer side of the storey and a smaller slab (5) for the inner side. The respective larger slabs bear one upon the other and the smaller slabs similarly bear one upon the other. The building storey has a floor slab and at least one side wall segment as a double wall element fixed to the edge of the floor slab.

Description

The present invention relates to a building floor part with a floor plate and at least one side wall segment made of a double wall element poured with concrete, which is placed on top of the floor plate at the edge of the floor plate.

The usual method of producing building floors, especially basements, from finished parts assembled on site, has been to concrete the floor slab in the conventional way and to apply prefabricated wall elements to it after the floor slab has been cured, see for example DE-U-298 05 829. From a predominantly economic point of view, a combination of ready-made concrete slabs and prefabricated concrete is increasingly used for the construction of basements. The double wall, also known as double wall or triple wall, offers good conditions for this. The floor slabs with the same function are double, triple or triple walls, as in the case of a two-level prefabricated floor slab.

To prevent water penetration or entry into the structure, waterproof concrete is used as seals for both the previously separately concrete floor slab and the filling of the double wall elements and joint seals are made with materials according to standard criteria.

The disadvantage of all the systems known so far with the combination of double wall elements and waterproof concrete is that the floor plate and the walls cannot be concrete in one work process.

The present invention is therefore based on the task of proposing a method whereby the floor plate can be produced within one day together with the walls and, if necessary, the ceilings, without additionally creating a concrete fuse as a weak point.

The invention relates to a building floor part in accordance with the main claim and a building floor made of such floor parts.

According to the invention, the floor panel is formed as a double wall element from at least one floor panel segment and the space in the double walls of the floor panel segment and one or more side wall segments is filled continuously in combination with concrete. This special measure, namely the use of a double wall element for the floor panel, makes it possible to create the space with suitable concrete in a cast and thus eliminate the undesirable partitions. Moreover, this allows the floor panel to be produced within one day with at least the walls and, if desired, also with the ceilings. The building floor and basement floor are cost-effective for building rooms.

A particular advantage is that, in principle, the same double wall elements can be used for both the floor and the walls. Since the floor plate can be made up of one or more floor plate segments and the individual wall surfaces can also be made up of one or more sidewall segments, the singular is used below to simplify.

In a particularly favourable design, the double wall elements of the floor panel segment and the side wall segment are made of a first larger plate for the outside of the floor and a smaller plate for the inside of the floor. Furthermore, they are matched in dimensions so that the larger plate of the respective side wall segment is on the larger plate of the floor panel segment and the smaller plate of the respective side wall segment is on the smaller plate of the floor bed segment.

To permit the compaction of the concrete entering the floor slab segment and to facilitate the filling of this area, openings are placed in the smaller plate of the floor slab segment on the inside of the floor, spaced apart, to the space between the double walls. These are packed after hardening, so that the application of a squeeze is not necessary for the smooth floor. The alignments are arranged in such a way that a sufficient sealing is made through the shakers from the respective opening. Usually, a sealing in each direction of about 40 cm is assumed, so that a corresponding sealing is provided every 80 cm.

As mentioned above, the floor of the floor can be made of several such floor plate segments. For this purpose, according to further training, the impact point between the floor plate segments in the gap in the double wall element is covered. These impact points are easily accessible, since in the above-mentioned area a free space is created by the above-mentioned area-smaller plate of the double wall element due to the design. The sealing here, as well as at the impact point in the outer area between the wall segment and the floor plate segment, is done by a hot-glued bitumen rail.

The use of double wall elements can also be used for the floor slab area without prior concrete placement. For the floor slab, the usual and well-known prefabricated ceiling slabs with pre-reinforced reinforcement are also used and placed on the double wall elements of the wall segments in such a way that the space between the double walls is not covered. Then, in a concrete placement process, the sidewalls, the floor and the ceiling slab can be cemented with appropriate concrete pumps, so that the entire basement carries a continuous connected concrete placement. This increases the stability and cost of manufacturing.

The above mentioned task is also solved by a procedure having the characteristics of a procedural claim.

The method of manufacture of a building floor consists of at least one floor panel segment, several side panel segments and at least one ceiling segment, whereby the floor panel segments and the side panel segments are formed as double wall elements with different size wall panels and the ceiling elements as a finished sub-panel, as described below, provided that the substrate for the floor panel is prepared in the usual and known manner.

First, at least one floor panel segment with the larger wall panel is placed on the prepared substrate. The substrate has a gravel filter and a thin layer of concrete if appropriate. Next, the side walls with the larger wall panel facing outwards are placed on the floor panel segment (s) in such a way that the smaller wall panels and the larger wall panels are aligned with each other and the space between the floor panel segments and the wall segments is connected. Then the ceiling segments are placed on the wall segments without closing the space between the double wall elements and the upper side segments. Finally, the flattened segments and the floor surfaces of the main sections are poured out simultaneously with a water-cooled covering, for example in concrete.

The concrete is compacted in the floor slab segments through specially designed openings.

In the case of a shell manufactured in accordance with the invention, the desired stability is thus achieved at a low cost while avoiding weaknesses.

The following illustrations, together with the accompanying drawings, give a detailed description of the invention by means of an example of an embodiment: Figure 1 shows the schematic cross-sectional representation of a wall segment on a floor slab segment with a second floor slab segment following it and Figure 2 the schematic cross-sectional representation of a floor with complete site concrete casting.

Figure 1 shows two floor slab segments 1, 2 and a side wall segment placed on the left floor slab segment 2, 3 such segments are usually of a maximum width of 3 m and a length of 7-8 m depending on the requirement.

All segments 1 to 3 are formed as double wall elements and consist of a larger outer finished part 4 and an inner smaller finished part 5 connected by a grid mounting 6 The dimensions of the floor panel segments 1, 2 and the side panel segments 3 in terms of thickness can be adjusted according to the requirements.

As shown in Figure 1, the sidewall segments 3 are placed on the floor segment 1 in such a way that the finished part 4 of the sidewall segment 3 is on the floor segment 4 and the sidewall segment 5 on the floor segment 1 and, for static reasons, a connecting bracket 7 may be added as a corner connection before installation.

The finished part plate 5 of the floor plate segments 1, 2 has openings 8 which are indicated in the figure schematically and not in scale. These openings are used for the introduction of the concrete and the subsequent shaking and compaction of the concrete.

The interposition of the two floor plate segments 1, 2 creates a clearance above the impact point 9 between the two outer finished plate 4 of the two floor plate segments 1, 2 through which a hot-glued bitumen track 10 can be placed over the impact point to prevent moisture or water from entering at that point.

After the bonding, a bonding proof 14 is also applied to the free space 13 above the impact point 9.

As an additional protection against moisture entry, bitumen-coated seam plates may be placed in the area of the impact points 9, 11 and Figure 2 shows a part of a floor already poured with concrete with the segments 1 to 3 already described in Figure 1. In addition, the figure shows a load-bearing inner wall 16 which is also made of concrete in this example. This supports the floor 17 ceiling, which also consists of a finished partition with reinforcement 18 and was concrete immediately after the pouring of the intermediate space. This produces a floor with a complete continuous concrete core assembly that does not have joints that need to be specially reworked.

For smaller floors, the finished part 19 of floor deck 17 is on a second side wall segment. The support can be provided by means of appropriate non-shown supporting elements, without the need for prior concrete, which are supported on the finished part 5 of the respective floor plate segment 1.
