NO822802L - DEVICE FOR AA CONNECTING MORE BUILDING STONES USING PLASTIC - Google Patents

Description

i The invention relates to a device as stated in

the introduction to claim 1. These building blocks exhibit large I

tolerances regarding the external dimensions, so that the binding of such Stones using a synthetic material; for better heat and sound insulation, whereby two or more

Building stones are cast in a form into a stone unit with the desired wall thickness, causing considerable work. This work consists in a pre-sorting of building stones in a consistent variable form or in filling the form with foils in places with smaller building stones, must avoid that the building blocks' difference in size results in

jen plastic overfill. Furthermore, the form rafts require a j

[i

Deicing agent so that the plastic that is molded in between

jthe building blocks come loose from the inner walls.

' The purpose of the invention is to reduce the mentioned

(use of time and materials.

According to the invention, this task is solved by the |

characteristic features according to claim 1. A foam rubber layer has, in tests, proven to be fully satisfactory for highlighting differences in the dimensions of the building blocks so that

! ' The sub-requirements indicate appropriate further developments. According to claim 2, not all the inner surfaces of the mold need to be coated with the layer according to claim 1. The tolerance differences in the thickness of the building blocks can be compensated by means of the thickness of the connecting layer. Claim 3 specifies an appropriate embodiment: of the form.

I Of fig. 2, it will appear that despite the fact that the height of the building blocks 15 and 18 falls below the determined height 20, and the height of the building block 14 exceeds this height, there will be no need for further precautions for

to avoid an overfilling with plastic. Depending on the height of the building stones, the foam rubber layer 11 is pressed more or less together, so that a closed cavity is formed between the stones to be connected. The thickness of the foam rubber layer depends on the tolerance ranges of the building blocks. Usually, this layer is 3-5 mm thick (unloaded).

It is of course also possible to connect three or more building blocks with each other, or choose a form length where only two units, or four or more units can

Claims (3)

jl. Device for connecting several, preferably square-shaped building stones to each other at a side surface by means of a synthetic material, in particular a foamed polyurethane mixture, to a larger stone unit by means of a mold consisting of rigid plates, the mold cavity being plated ; With a layer, characterized in that this layer consists of foam-in-rubber (11) or other material that can easily be compressed for a few millimeters attached to the inner walls of the mold (1), as well as a thinner covering layer (12), ; preferably of low-density polyethylene. i' 2. Device according to claim 1, with a square shaped cavity consisting of six internal surfaces, characterized in that four of the six. inner surfaces (plates 2- - 7) are coated with foam rubber, namely the inner faces that are perpendicular to the faces of the cuboid in the building blocks (14 - 19) which are connected to each other. 3. Device according to claim 2, characterized in that two adjacent inner surfaces of the four inner surfaces coated with foam rubber (plates 2-5) belong to mutually rigidly connected plates (3, 4) with which the other plates (2, 5) are articulated.
