HOLLOW PRE-FABRICATED COMPONENT FOR ERECTING WALLS AND THE LIKE.

The invention relates to a hollow prefabricated component For erecting walls and the like., The two via cavities having forming webs integrally connected side walls, the height of the webs is less than that of the Side walls. Hollow prefabricated components of this type are known - They are made of wood-concrete (wood shavings or sawdust, cement, chemicals). To well-known prefabricated part of this Art to be trained in such a way that it can also be used by non-specialists can be relocated, it was recommended to ensure that

that at least two of the webs over the one longitudinal - Overhang the narrow side surfaces of the side walls. This hollow prefabricated parts to make them easier,

made of wood wool cement, all of the interior wall surfaces delimiting the cavities were sloping surfaces, albeit with relatively low inclination.

write from the sheet concerned

The last-mentioned prefabricated elements mentioned in were pressed in one operation, have proven themselves,

that,

but have the disadvantage / if they are placed on a base for themselves, the protruding webs can be damaged.

The invention has for its object to form the aforementioned known hollow prefabricated parts so that the the aforementioned disadvantage does not occur, and that on the one hand sufficient between prefabricated components arranged one above the other Space is available to insert rebar and on the other hand the concrete to be poured easily everywhere there to be able to lead where he should fill cavities after the prefabricated parts are arranged one above the other. To solve this problem, it is proposed according to the invention to ensure that the middle area of each web top and each web bottom is a distance from those defined by the top and bottom of the side walls Has levels. It is also advisable to ensure that the middle area of each web underside from the through the undersides of the side walls defined plane has a greater distance than the middle area of the web top from the corresponding other level. "It is recommended to have the upper and lower sides of the webs curved to train.

So that such prefabricated parts can now also be assigned to one another by non-peasants, after Another feature of the invention proposed each Side wall both in the area of the top and in the area of the underside of the prefabricated component with a To provide longitudinal recess that are on top of each other facing or facing away from one another, facing away from one another on the upper side or facing one another.

The invention is explained below on the basis of several exemplary embodiments. It shows :

Fig. 1 is a side view of a prefabricated component according to the invention,

FIG. 2 shows a section along the line If-II of FIG. 1, FIG. 5 shows a plan view of the prefabricated component according to FIG. 1,

4 shows a section through a modified prefabricated component., in an enlarged view similar to the section according to FIG. 2,

Fig. 5 shows two prefabricated parts according to Figure 1, after each one side wall of each prefabricated component is shortened by cutting to the nearest web has been.

The two side walls 1 and 2 of each prefabricated component are as known per se, via webs J integral with them

connected with each other. All of the cavities formed delimiting side surfaces are slightly inclined, placed, in order to be able to easily demould the prefabricated component produced by pressing. The middle area 5 each The web top and the middle area β of each web bottom has from that through the top surfaces of the Side walls 1 and 2 defined level 7 or from the level Ö defined by the web undersides a pTostand. Although in the exemplary embodiment, the upper and lower sides of the webs are shown curved, needs If this is not the case, these areas can also consist of several partial areas.

The prefabricated component shown in section in FIG differs from the prefabricated part in Figures 1-3 in that its side walls are in the region of the upper sides the same longitudinal recesses 9 and 10 and in the area of Undersides of the side walls of longitudinal recesses 11 and 12 exhibit. The longitudinal recesses 9 and 10 are mutually exclusive facing away, the longitudinal recesses 11 and 12 facing each other, so that prefabricated components designed in the same way ^, arranged one above the other ^ interlock, it will thus achieved the same thing as each other in another way known prefabricated parts, only the surfaces are! Tilt which a prefabricated part, if it is on a flat surface

is deposited, this pad touches., area larger than with the previously known prefabricated components. In addition, it can be seen from the exemplary embodiment in FIG. 4 that the central area of each lower side of the web is at a greater distance from the plane 8 defined by the undersides of the cross winds than the central area of the upper side of the web is at a greater distance from the other plane J, the radius of curvature r, is slightly larger than the radius of curvature r _? . It is thus not only achieved that reinforcing iron can be inserted easily, but also that sufficient passage cross-sections are available for concrete to be poured. Of course, if the prefabricated components are used as lintels for windows and the like, these reinforcing bars must be supported by spacers in order to achieve the encasing with in-situ concrete.

Figure 5 shows two prefabricated parts according to Figures 1-.3, whose side walls 1 "to the nearest web at one end have been shortened. When assembling these prefabricated parts This then results in a cavity 13 in the area of Corner 14, which, like the other cavities, is filled with concrete and the butt-jointing prefabricated components are also flawless against each other.
