Description

Title: Wing floor element made of concrete.
The invention relates to a prefabricated floor element of concrete, at least consisting of a cantilevered beam-shaped part, provided with longitudinal hollow channels and parallel reinforcing wires.
Such floor elements are known in practice under the name "hollow core slab floors" and are shown, for example, in Figure 1B of EP-B-0.634.966. The maximum width of these hollow floor slabs is 1200 mm, because a larger width requires the application of transverse reinforcement, which is problematic with the hitherto known production techniques.
The application of "hollow core slab floors" in residential and non-residential construction offers, in addition to major advantages such as the speed of installation and the immediate accessibility of the floor elements laid on a supporting construction, the following important disadvantages: - the joints or seams between adjacent floor slabs must be somehow closed. This leads to shrinkage cracks over time without additional measures.
- pipes must be placed on the floor, they can hardly or not be concealed in the floor.
Due to the dimensions in designs, it is generally not possible to use a limited number of floor plates standardized in terms of width. A width adjustment of hollow floor slabs is difficult to implement in terms of production. The installation of a large recess in the floor, such as, for example, a stairwell and the like, requires additional constructional measures, such as, for example, the use of trimming irons.
Another type of prefabricated concrete floor element is known in practice under the name "formwork floor slab". This floor element consists of a relatively thin and therefore not self-supporting floor plate provided with longitudinal and 1003858 2 transverse reinforcement with reinforcing elements protruding outside the top surface. These floor elements are applied as a formwork floor, on which a layer of concrete, with additional reinforcement, is then poured. The formwork floor must be stamped. The entire floor has no through seams and therefore remains flat, while pipes can be concealed in the floor. It is relatively simple to change the width and / or the inclination of the floor elements, and it is also relatively easy to make recesses in the floor, such as for instance a stairwell. However, the substitution work slows down the construction process and the floor thus composed is only passable and loadable after sufficient curing of the in-situ poured concrete.
The object of the invention is to provide a prefabricated floor element which obviates the drawbacks of the above two known floor elements and combines the advantages thereof. This object is achieved according to the invention by providing a floor element of the above-described type, wherein the beam-shaped part is provided on at least one side with a laterally projecting wing, the bottom surface of which corresponds to the bottom surface of the beam-shaped part, while the thickness of the wing is considerably smaller than that of the beam-shaped part.
Preferably, the beam-shaped part is provided on both sides with laterally projecting wings, which are provided with both longitudinal and transverse reinforcement wires, which transverse reinforcement wires extend into the bottom layer of the beam-shaped part.
When applying a floor constructed from prefabricated floor elements, the floor elements are placed with the side edges of the wings against each other. Above these wings, therefore, a channel is created in which all kinds of pipes can be fitted, after which this space is filled with concrete in the work. The top surface 1003858 3 of the in-situ poured concrete, unlike adjoining hollow core slabs, can adjoin the top surface of the adjacent beam-shaped parts of the floor elements. A transverse reinforcement can be omitted with a small vent width. The maximum wing width is then determined by the allowable deflection of the wings. In the preferred wide wings, which can for instance have a width of half the width of the beam-shaped part, both longitudinal and transverse reinforcement are necessary. The transverse reinforcement, which is not present for the indicated reason for the channel floor plates discussed above, can be applied to the floor elements according to the invention because the method for manufacturing them is split into two steps. During a first molding operation, a continuous layer is formed with the thickness of the wings, in which layer a reinforcement can be applied, while in a second step the top layer of the beam-shaped part is formed on the bottom layer formed in the first step. is applied. Further details of the floor element according to the invention are described in the subclaims.
Embodiments of the floor element according to the invention are further elucidated with reference to the drawing. Herein: figure 1 - a floor element according to a first embodiment, figure 2 - a floor element according to a second embodiment, which has a considerably greater width compared to the floor element according to figure 1, figure 3 - an isometric drawing of a floor element with an embodiment detail according to the invention, and figure 4 - an example of a floor field built up from floor elements according to the invention with a stairwell arranged therein.
The wing floor element 1, as shown in figure 1, consists of a central beam-shaped 1003858 4 part 2 with wings 3 formed on either side. The width B of the beam-shaped part is, for example, 600 mm, while the width b of the wings is 300 mm is. four hollow channels 4 are provided in the beam-shaped part 2 for saving material and weight. In the upper part 9 of the beam-shaped part 2, longitudinal reinforcement wires 5 are arranged parallel to the channels 4. The bottom surface 11 of the wings 3 is in line with the bottom surface of the beam-shaped part 2. The thickness D of the beam-shaped part can for instance amount to 180-200 mm and the wing thickness d is 50-70 mm. The thickness sizes D and d depend on the desired degree of fire resistance of the floor element 1, or other building physics and construction requirements.
Using a mold-casting process, a layer of concrete is formed in a first step at the width of the wing floor element 1 at the location of the wings 3. In this first layer, both a longitudinal reinforcement 6 and a transverse reinforcement 7 are applied. The top layer 9 of the beam-shaped part 2 is then formed on the top surface 12 of this first layer. Reinforcing elements 10 protrude from the top surface 12 of the wings 3 to support additional reinforcement and absorption of possible shear forces in the concrete to be poured in the work to fill the space, which is bounded by two abutting wings 3 of neighboring wing floor elements 1 and the upward facing sides of the beam-shaped parts 2 of those wing floor elements 1.
The wing floor element as shown in figure 2 differs from the wing floor element according to figure 1 in that both the width B of the beam-shaped part 2 and the width b of the wings 3 have been increased by a factor of 2. The number of longitudinal channels 4 in the beam-shaped part 2 has therefore doubled.
The width b of the wings can be easily adjusted and this width can also be zero, so that only one wing projecting sideways is molded onto the beam-shaped part 2. The wings 3 can also be given a certain slant in the longitudinal direction if this is desired. The length of the wing floor element 1 can be chosen arbitrarily. In principle, the length of the beam-shaped part 2 and of the wings 3 will be the same. A 5 sloping end face is possible. The top layer 9 of the beam-shaped part 2 can be given a shorter length than the wings as shown in figure 3, in which the wings extend in a longitudinal direction a distance h, at least on one side, from the end of the beam-shaped part 2.
This length difference h is extremely useful in wing floor elements, which are used at the location of a recess in the floor, for example a stairwell, because this provides the possibility of applying a transverse reinforcement, which is poured into the in-work. concrete is included.
Figure 4 shows, by way of example, a floor field 20 constructed from wing-floor elements, the dimensions of which are 8300 x 5330 mm. A stairwell 26 has been cut into the floor, the dimensions of which are 2060 x 1050 mm 20. The floor 20 is composed of five wing floor elements 22-25, which rest with their end edges on a circumferential supporting edge 21 of a supporting construction, which is formed for instance by walls. The outer floor elements 22 also rest with their long sides on this edge 21.
Both floor elements 22 have a beam-shaped part with a width B of 600 mm, to which a single side wing with a width of 130 mm connects. The adjoining floor element 23 has a beam-shaped part with a width B 30 of 1200 mm, on which wings with a width of 600 mm are arranged on either side. The floor element 24 has a beam-shaped part with a width of 1200 mm and wings arranged on either side with a width of 600 mm. The wings or the bottom layer 8 of the beam-shaped element continue to the stairwell, the top part 9 of the beam-shaped element ending at a certain distance from the end edge of the wings. The floor element 24 1003858 6 is therefore of the type as shown in figure 3. The floor element 25 is connected to the floor element 24, the width of the beam-shaped part 2 of which is also 1200 mm, provided on both sides with 5 wings with a width of 420 mm. All beam-shaped parts of the floor elements 22-25 therefore have a width of 600 and 1200 mm, respectively. The wing width of the floor elements 22 and 25 is adapted to the design depth of the floor and the location of the stairwell 26. An end of the floor element 24 does not find support on the circumferential edge 21 and must therefore be temporarily supported in another way, for example, by the possibly supported formwork of the stairwell 26 in the work from the boxes.
After the floor elements 22-25 have been placed, with the wing edges against each other and the necessary pipes have been placed in the spaces located above the wings, these spaces are filled with concrete, which is leveled at the height of the adjacent floor elements. In advance 20, the reinforcement elements 27 are arranged near the stairwell to obtain a firm support of the end of the floor element 24 by the neighboring floor elements 23 and 25. The reinforcement elements 27 can take the form of so-called hidden consoles or of a continuous trimming strip. The shaded areas in Fig. 4 indicate the in-situ concrete. The dashed lines present in those shaded areas indicate the location where adjacent floor elements abut against each other with the wing edges.
