[0001] The invention relates to a thermal insulated building element, which together with
connecting elements is suitable for making a building system quickly, which is also
suitable for housing and exact fastening of any reinforcement.
[0002] Due to the development of building technologies, introducing of new materials, great
changes have taken place in the building industry. The requirement of proper thermal
insulation values in building systems providing high quality buildings in a short
time is an ordinary claim nowadays. The most frequently used material in the construction
industry is still concrete as the proper thermal insulation of concrete can be ensured.
[0003] In the state of art Hungarian utility model
HU U 2348 makes known a thermal insulated building element. Here the solution is, that the
building element is covered with polystyrene panels on both outer and inner sides,
and the space between the polystyrene panels on the outer and inner sides is filled
with load-bearing concrete and occasionally reinforcement is put into the concrete.
The parallel polystyrene panels on the outer and inner sides are fixed by connecting
cross clamps and on the side edges of the polystyrene panels groove profile and bolt
profiles fitting each other are formed.
[0004] The characteristics of the solution made known there is, that the connecting cross
clamps have rectangular cross section, the thickness of which is preferably 1.5- 5
mm, width 20-50 mm and there are perforations of 6 - 12.5 mm size in the middle line
of the width corresponding with the thickness of the building element in the distance
of 120, 250, 300, 360 mm and at each end of the cross clamp holes of circular shape
housing the closing pipe or section holes housing the closing bolt are formed. In
the polystyrene panel there are holes of vertical position from the inner side towards
the outer side conforming with the rectangular section of the connecting cross clamps,
into which the connecting cross clamps are pushed in the position of connecting the
polystyrene panel and there are parallel circle shape holes or section shape holes
of horizontal position in the outer side of the polystyrene panel going through the
opening crosswise, closing pipes or closing bolts fastening the polystyrene panels
are fixed to the hole of circle or section shape and at the side edges of the polystyrene
panels there are protruding ribs on both sides of the bolt-profile, whereas on both
sides of the groove profile there are arched, lengthwise channels.

[0009] Document
US 2002/017070 A1 discloses a foamed plastic module for building an insulated concrete wall structure
by stacking the modules together until the desired configuration of the structure
is completed, and when the form is filled, a concrete monolithic waffle wall structure
having foam insulation permanently attached to the opposed wall surfaces to form the
inner and outer wall surfaces of an enclosure is realized. The module is made of foamed
plastic material, such as expanded polystyrene, and is built in a pressure molding
apparatus. Each module comprises a rigid form block of a generally rectangular configuration
having a hollow interior of a particular predetermined configuration formed between
spaced apart confronting sidewalls to form a cement waffle wall. The side walls of
the module are secured one to the other by a plurality of spaced tension members that
can be formed of metal or plastic material. When formed of plastic, the tension members
can have plastic rebar seats into which reinforcing steel can be snapped and held
in position. The tension members are positioned at evenly spaced centers, including
across adjoining modules, whereby the flanges thereof can be more easily located.
Location of the recessed flanges is also accomplished by incorporation of molded raised
vertical lines or depressed divets centered over the flanges and visible externally
on the surface of the waffle wall module. When stacked vertically employing per-molded
corner modules, the tension members, and internal horizontal and vertical core elements
of the waffle wall are all evenly aligned.
[0010] When working out the solution according to the invention we aimed to realize a thermal
insulated building element, which ensures placement of any reinforcement beside ensuring
quick and easy process.
[0011] Working out the solution we realized, that if we connect elements made of polystyrene
foam and joined with specially shaped connecting elements, which can ensure suitable
placement and location of any reinforcement while necessary space of polystyrene element
is ensured, then the set aim can be achieved.
[0012] The invention is a thermal insulated building element, which has joined polystyrene
elements with a loadbearing part containing a metal framework between the polystyrene
elements said loadbearing part is filled with concrete in-site, furthermore has connecting

elements joining the polystyrene elements (1) are plastic connecting elements (19)
where fastening holes (8) serving joining the polystyrene elements (1) as well as
nests (20) joining a framework (18) in a space (30) between the polystyrene elements
(1) are formed, wherein the plastic connecting elements (19) are placed and fixed

the polystyrene elements 1 takes place as follows: The flexible connecting element
is placed into one of the grooves 3 formed on the edge of one of the polystyrene elements
1, which is flexibly fixed with the straining profile 25 in the groove 3. Joining
of the building elements according to the invention takes place with placing the connecting
elements 21 to the sides of the polystyrene elements 1, then the adjoining polystyrene
element 1 with the groove 3 on its side fit into this polystyrene element 1 and push
it on to the connection profile 21. This way the adjoining building elements are fixed
without shifting, which gives sufficient hold and positioning during compiling and
filling with concrete.

to ensure statical stability of the wall a hollow 28 suitable for forming a vertical
pillar is formed in the polystyrene element 1. Building of the wall takes place according
to the method described according to the invention.

Fig 21 with the framework. Fig 23 shows the elevation view from I-I section of the
girdle element joining the building element with the framework. Fig 24 shows the perspective
from I-I section of the building element with the framework. We had to take into consideration
when creating the thermal insulated building element shown in figure 13, that in case
of the basic formation, the solution is not suitable for making a girdle. To make
it possible, we apply a possible embodiment of the formwork according to the invention.
It can be seen in the figure, that a hollow 27 suitable for housing the relative reinforcement
and forming the girdle is formed in the girdle 26 elements. The girdle 26 elements
are connected with the connecting element 19, on which the framework 18 is placed.
[0025] Fig 25 shows a possible embodiment of the building-in of the building element according
to the invention. In special purpose buildings, such as very tall buildings, or freezing
houses beside keeping thermal insulation characteristics keeping structural parameters
is also necessary. It can be ensured by the solution according to the invention such
a way, that the polystyrene elements 1 and the connecting elements 19 as well as with
the help of the framework 18 solutions in accordance with statical structural measurements.
[0026] In case of a possible preferable embodiment of the solution according to the invention
formation of the interim supports of the skeletal frame takes place with the help
of a steel bar led between the parallel guiding elements in wave-form. Another possible
preferable embodiment is, when forming of the interim supports of the skeletal frame
is solved by a ladder-like straight connection between the parallel guiding elements.
[0027] Connecting of the lateral and bottom-top edges of the polystyrene elements is solved
by a long plastic strap, which is put into the lengthwise groove made into the edges
of the polystyrene elements, and when pushed together it flips into the edges of the
polystyrene elements and flexibly closing there. When assembly takes place, the reinforcement
is simply pushed between the polystyrene walls 1, then the plastic straps are pushed
as well. This solution makes possible the application of the pre-fabricated interior
reinforcements, for example application of steel grid. Notches in the walls and sides
of the polystyrene element walls are formed with heat cut or grooving.
[0028] The advantage of the solution according to the invention is, that it makes possible
easy and quick production of various thermal insulated walls in-site. Structural formation
makes possible beside simple and durable connecting of polystyrene elements the placing
and positioning of several reinforcements, grids, loadbearing structures.
