Since these strips are used to strengthen the webs in the reguisite manner, their thickn~ss is several times that of the thicXness of the webs.

2~64~14 insulating strips and the end face of the concrete block are generally coplanar with each other.
If, however, a block-making machine that does not compact the concrete material that is pouxed into the mold to such an extent is used, then the top side of the block may become situated above the bottom side of the reinforcing strips.
This causes unwanted recesses to clevelop above the insulating inserts after the block is formed. This problem cannot be solved merely by diminishing the thickness o~ the strips situated below the webs, since such a strategy could well reduce strength of the webs to the~ point where they are not sufficiently strong to satisfy the requirements of the operation.
There remains a need for a device for manufacturing building blocks whose webs are reinforced that also provides that after the concrete material has been poured in and compacted, the end faces of the insulating inserts are situated in the end face of the concr~t~ block.
Summary of the Invention The invention meets this need by forming at least one web either with a strip that reinforces the web on its top side or with a strip that provides reinforcement to the web on its bottom side, and that penetrates into the insulating insert.
The web is preferably formed on the top side of the mold with a strip that extends over its entire length. This strip can have a height approximately equal to the width of the web situated between the recesses, exclusive of the web's lateral projections. Its thickness can be from one to three times the thickness of the web. According to another embodiment, this strip can have a height equal to one to two times the thickness of the web, and a width equal to the width of the web, exclusive of the web's lateral projections.
In another embodiment, at least one strip protrudes from the web downwards; it can likewise extend over the entire length of the web. It can be designed thereby as a narrow strip with a rect:angular cross-section, on whose bottom side pins are configured to secure the insulating insert. However, it can also widen in cross-section toward the bottom and be 206~
used to secure the insulating inserts in a dovetail like configuration.

Detailed DescriPtion A mold 1 with a prism-shaped housing 11 is depicted in Fig. 1. It is formed on its top side with a frame 12 that projects upwardly towards the top. ~n the lower area, flanges 13 protrude ~rom the housing 11. The flanges enable the mold 1 to be gripped, lifted up and lowered> In its middle area, the mold 1 is subdivided by a partition 15 into two chambers.
Accordingly, with this type of mold 1, two concrete blocks can be manufactured at the same time.
On its top side, the mold 1 is provided with two webs 20 for covering the insulating inserts 30O These webs 20 extend from one side of the mold 1 to the other side and are designed to have lateral projections 22, whereby the formation of the webs 20 corresponds in each case to the cross-section of two 206~41~
insulating inserts 30 placed in the mold. To secure the insulating inserts 30, pins 23 protrude downwardly ~rom the webs 20.
To manufacture a concrete block using mold 1, the mold is first placed on a level surface. Concrete material is introduced into the mold through t:he recesses 25 located on the top side of the mold 1 about t:he webs 20 until the mold is completely filled. The mold 1 is then simultaneously subjected to a shaking process and the application of a press, which plunges from above into the mold 1. The concrete material is thereby compacted to such an extent that its top surface lies in the plane of the bottom side of the webs 20, as indicated in the figure by the broken line 26.
In such a design, however, the thickness of the webs 20 is not suf f icient to guarantee the required mechanical strength. One must take into consideration that the webs 20 extend over the entire width of the mold 1, and that strong impacts are exerted on these webs when the concrete material is introduced into the mold 1, which can cause them to deform.
Accordingly, for the webs 20 to exhibit the required strength, a strip 21 is provided on their top sides that extends over the entire width of the mold 1. This strip is rigidly connected ~e.g., welded) to the webs 20, and these strips reinforce the webs in the requisite manner. The thicXness of these strips 21 generally corresponds to the thickness of the webs 20; their height generally corresponds to half the width of the webs 20.
The second embodiment depicted in Figs. 3 and 4 differs from the first embodiment in that the reinforcing strips 21a which extend over the entire width of the mold 1 for the webs 20 are designed to have a width equal to the width of the webs 20, exclusive of the projections 22, which form a tooth construction. Also, their thickness is approximately double the thickness of the webs 20.
The third embodiment depicted in Figs. 5 and 6 differs from the first embodiment in that the strips 21b which extend over the length of the webs 20 are provided on the bottom side ,, ; ; , , , ,, , , ,, ~ , . .. . . .: .. , ' ` .! . .~
20~414 of the webs 20 and protrude downwardly therefrom, and bear pins 23 which protrude downwardly. They are d0signed to be sufficiently narrow, so that they penetrate, along with the pins 23, into the insulating inserts 30, in which slits are molded that correspond to the profile of the strips 21b and are used to secure the strips within the mold 1. The thickness of these reinforcing strips 21b thereby approximates the thickness of the webs 20, and their height is generally half the width of the webs 20.
The ~ourth embodiment depicted in Figs. 7 and 8 differs from the third embodiment in that the strips 21c protruding downwardly from the webs 20 are formed so that they widen in a wedge shape toward the bottom. This enables them to provide a secure attachment with respect to the insulating inserts 30 within the mold 1, although they are not formed with pins that r protrude downward. The average width of these reinforcing strips 21c is approximately the same as the thickness of the webs 20, and their height is equal more or less to half the width of the webs 20. As is apparent from Fig. 8, this mold is formed with recesses 16 in one of the housing surfaces.
These recesses are provided with guide surfaces 17, through which means the insulating inserts 30 can be inserted laterally into the mold 1, in which they are retained by the strips 21c.
If, however, a block-making machine that does not compact the concrete material that is pouxed into the mold to such an extent is used, then the top side of the block may become situated above the bottom side of the reinforcing strips.
This causes unwanted recesses to clevelop above the insulating inserts after the block is formed. This problem cannot be solved merely by diminishing the thickness o~ the strips situated below the webs, since such a strategy could well reduce strength of the webs to the~ point where they are not sufficiently strong to satisfy the requirements of the operation.
