Hollow structural formwork for shell concrete construction File number:

B- 66 428 / 37a

Field of use:

The invention relates to a structural formwork hollow body for cladding concrete construction, which is prefabricated in the factory on the construction site is delivered.

The individual hollow building formwork bodies are lined up, placed on top of one another and then filled with concrete. They form what is known as permanent formwork that insulates atter or can isolate.

Purpose;

By using this hollow building formwork, the following are valued Purposes pursued and achieved:

a) working time savings,

b) Use of unskilled unskilled labor for building shell construction,

c) Improvement of the possibilities for "do-it- ^{yourself tf} ,

d) Saving the otherwise necessary visualization,

e) saving money,

f) Breathing of the otherwise hardly "breathing" concrete wall and thus improvement the climatic conditions within the structure,

g) Use according to any architect's plan, as it is easy to predict at all points, as the plan prescribes,

h) improvement of the thermal insulation values,
i) Improvement of the acoustic insulation.

State of the art;

The concrete-clad construction has been well known for a long time.

With her they were dressed in a coat made of plates Construction site, at the point where a wall was to be erected, with a certain distance, next to each other and on top of each other ^ - stellir, then concrete filled.

The plates were previously connected loosely with wire anchors, metal strips, etc. before they were filled.

That had some downsides that look negative on the application the concrete shell construction.

The erection of such formwork requires skilled workers who have to work very precisely and sometimes an additional one Formwork is required because the pouring pressure of the concrete can push the panels apart. In addition, the walls hardly have any

Have breathing possibilities. Working time savings were rare recorded.

Task s

The invention aims to overcome these disadvantages. Solution:

This object is achieved according to the invention in that a) already In terms of fabrication, the plates are firmly attached to one another by their spacers are connected and "boxes" = hollow bodies are created, b) there are overlaps, which means that without precise assembly Stacking of the individual structural formwork hollow bodies also for; a layman can do this without difficulty, - e) the spacers allow the walls to breathe.

Description of an embodiment:

An embodiment of the invention is shown in the drawing and is described in more detail below?

a.) The building formwork hollow body consists of the 2 side parts ('F) and the 2 or more spacers (A) that hold the side parts (B) by nailing, screwing or gluing stick together. -

b.) The side parts (b) are 2 wood-wool cement lightweight panels, or other panels made of insulating material, such as chipboard etc. and these possibly in connection with other materials, like foam ect., respectively. Plaster supports connected.

c :.) The spacers (A) are made of the same material or made of wood or a ventilated metal sheet.

d.) The construction formwork hollow bodies are, as can be seen from the drawing, placed side by side and placed on top of one another by means of the overlaps (G) of the spacers (A), whereby with; Concrete-fillable cavities are created into which the concrete is poured on the construction site.

e.) So that the resulting, individual concrete columns with the connection shaft, which is created between 2 adjacent building halves, - and with each other have a good connection, the spacers (A) are shorter than the height of the side parts (B). This creates the flow connection opening (E).

f.) By filling the built-up Bautenhalungs-Hohlköper with loading> clay creates a load-bearing concrete wall that can breathe through the spacers (A).

Achievable benefits:

The advantages achieved by the invention are already under "Purpose" listed individually.
