Il 74769

Prefabricated building elements! The present invention relates to a prefabricated building element for erecting cast-walled buildings according to the preamble of the claim.

Such an element is shaped so as to have an open side panel and a wall cladding panel which are parts of a mold and which are adapted to form the inner and outer sides of the finished wall, respectively, the two panels being fixedly connected to each other.

13 Cast-walled buildings are in many cases multi-storey buildings. The erection of multi-storey houses today takes place by mold casting of load-bearing pillars and beam elements. A brick wall is then laid between the pillars, etc. Another method is to use load-bearing façade elements made of concrete, which ZO then form a complete outer wall.

A disadvantage of the above-mentioned construction method is, among other things, the passage of time when casting columns, when, among other things, the mold timber has to be assembled and dismantled. Concrete building or Γ-5 facade elements limit transport possibilities and maneuverability due to their weight.

Therefore, it has also been proposed (Swedish patent application 7610977-6) to prefabricated formwork elements in which concrete or Senta roast is injected at the construction site itself and which are then included in a finished wall, the outer and inner side of which are formed by opposite walls of the formwork element. These known formwork elements are relatively small, which makes the erection of the wall relatively complex, time consuming and expensive.

The prior art is also represented by the solutions disclosed in AT patent publication 310 392 and DE application publications 22 28 967 and 28 36 862.

2,74769 AT-A-310 392 discloses a wall element which can be as high as the floor of a building and consist of several separate frames. These are connected to each other by means of a fiberglass cloth and a plastic filler, which is 5 complex and expensive.

According to the solution described in DE-A-28 36 862, the formwork wall to be installed consists, like the above-mentioned Austrian structure, of formwork sides formed by a plurality of superimposed elements, which is why it has the same drawbacks.

DE-A-22 22 967 also discloses a wall element which, like the 13 wall elements disclosed in the Austrian patent publication, consists of a plurality of vertical, stacked building element parts, which also have the above-mentioned drawbacks. Said building element has a facade plate higher than the side on the inner wall side.

2C

The object of the invention is to provide a wall element of the type mentioned at the beginning, which does not involve the disadvantages of the known elements.

This object is achieved by a building element according to the invention, in which the height of the wall element is substantially equal to the floor of the building. The façade panel of the element is higher than the wall cladding panel and at the same time forms a casting wall for the casting of the beam. The facade and wall cladding-30 panels are both seamlessly formed into one piece and connected to each other by means of vertical profile beams with openings for reinforcing steels. One beam is then located next to the other end of the wall element and projects laterally substantially the entire extent beyond the end edges of said plates to form a tongue, and the other beam is located at the opposite end of the element inside the end edges of the plates to form a groove.

Li 3 74769 More specifically, the element according to the invention is mainly characterized by what is stated in the characterizing part of the claim.

Other features and advantages of the invention will be apparent from the following detailed description and the accompanying drawings, which show schematically and by way of non-limiting example a preferred embodiment of the invention.

1C Figure 1 is a perspective view of a mold or building element with a window.

Figure 2 shows in a simplified cross-section the upper part of the lower wall element, the beam cast on it and the lower part of the wall element cast on it.

Figure 3 shows the casting of a wall element to a base plate, also in a simplified cross-section.

20

The wall element according to the invention, which is indicated in its entirety by reference numeral 10, consists of a facade panel 1 and a wall cladding panel 2, as well as intermediate latches 3> attached between these panels, which connect the panels to each other.

25

Certain wall elements are pre-equipped with a window 11 or doors or the like. As shown in Figure 1, the wall element 10 has substantially the same height as the floor level of the building.

30

Electrical and HVAC equipment is installed between plates 1 and 2.

The wall elements are light to carry due to their low weight, which is an advantage, for example, in exports.

35

When the building has to be erected, a concrete slab 4 with an anchoring or reinforcing iron 11a 5 is cast, on which the wall elements 10 are placed. In order to facilitate the placement of the wall element in the correct position on the base plate or beam 40 ton 4, the fastening members 12 shown schematically are used.

Claims (1)

4 74769 Concrete or other material is sprayed into the space between the facade panel 1 and the wall cladding panel 2, which gives the wall its load-bearing capacity. The walls can also be reinforced, as shown by reference numeral 7 in Figure 1. When all the wall elements of the floor level 5 are in place, a beam is cast, which is indicated in its entirety by reference numeral 6 and preferably comprises a reinforced concrete layer 14 reinforced with reinforcement 13. element 15. 10 As can be seen from Fig. 1, the facade plate 1 also serves as a mold wall when the beam 6 (Fig. 2) is cast. Once the beam 6 has been cast, the next floor level 15 is erected on top of this and so on. In order to strengthen and stabilize the structure, two wall elements 10 of different layers, located directly above each other or below, respectively, are combined with each other and with the intermediate beam 6 by means of cast reinforcing or anchoring irons 16. The invention provides a building with prefabricated wall cladding panels. no stubble erection with its associated disadvantages. Thanks to the invention, the disadvantages caused by heavy transports and time-consuming mold construction have also been eliminated. The financial benefits are obvious. The embodiment 30 described above and shown in the drawing is, of course, to be considered only as a non-limiting example, and its details may be modified in many ways within the scope of the following claim.
