Ti t I e: I MPROVED CONNECT! ON SYSTEM FOR CONNECT! NG WOOD ELEMENTS
TO A REI NFORCED CONCRETE ELEMENT OF A BUI LDI NG, METHOD FOR
PRODUCI NG THE CONNECT! ON, AND CONSTRUCT! ON KI T
* * * *
The present i nventi on rel at es to a connect i on system for
wooden el ements with a rei nf orced concrete el ement of a
bui I di ng accordi ng to the preambl e of cl ai m 1 and a met hod
usi ng the devi ce accordi ng to the i nventi on and a kit
accordi ng to the i nventi on.
The scope of the present i nventi on i s connect i ons between
structural wooden el ements and structural rei nf orced concrete
el ements. A part i cul ar probl em i n t hi s area i s that after the
rei nf orced concrete has been poured, either a wooden el ement
must be fastened usi ng a connect i ng devi ce that penetrates the
rei nf orced concrete or part of the devi ce must be i nserted
i nto the concrete formwork before pouri ng. The second met hod
i n part i cul ar requi res a hi gh I evel of preci si on that cannot
al ways be achi eyed due to the exact t ol erances for posi ti oni ng
and f asteni ng are only known after the components have been
cast or laid out. This is particularly problematic because i n
concrete constructi on the tol erances are i n the cm range,
whi le in wooden constructi on the t ol erances are i n the mm
range.
State of the art
A one-piece angle is known from EP 2 093 335, in which a first
part of the angl e i s fastened to a surf ace usi ng connect i ng
means, e.g. screws that penetrate the constructi on are
attached to a surface and a second component i s al so attached
at an angl e usi ng screws or nail s, creati ng a connect i on
between the two components.

From the GAH Al berts catal ogue, a brace bracket for masts and
the I i ke i s known, whi ch has a base that can be i nserted i nto
a concrete cast i ng, the base has a grooved structure and on
this base there is an L-shaped angle with holes for f asteni ng
a wooden component, e.g. a wooden post. The problem that
an ses with the consol e descri bed i s that the consol e must be
posi ti oned preci sel y and correctly before I ayi ng out and
subsequent concreti ng so that all t ol erances are adhered to.
From US 20200165812 a system for f asteni ng a concrete
foundation is known, whi ch then fixes an additional component.
However, there i s no system that all ows the base to be
adj usted after the concrete has been pl aced. The base i s
fastened mechani call y, whi ch requi res access to the f asteni ng
area and therefore an openi ng i n the wall for access to the
f asteni ng screws and al so does not all ow compensati on
t ol erances i n all di recti ons. The US publ i cat i on i s desi gned
for vertical forces and not lateral forces.
A f asteni ng system for a rei nf orced concrete base i s al so
known from US 5375384, but t hi s system does not all ow the base
to be adj usted after the concrete has been pl aced. The base i s
attached mechani call y, whi ch requi res access to the attachment
area and therefore an openi ng i n the wall to access the screws
for attachment and al so does not all ow for compensati on
t ol erances i n all di recti ons.
The US publ i cat i on i s desi gned for verti cal forces, not
lateral forces.
The ai m of the present i nventi on is to real i ze a system that
all ows, in a fi rst step, to posi ti on an el ement f ormi ng the
seat for the connect i ng devi ce, and i n t hi s way to obtai n
greater t ol erances i n posi ti oni ng before pouri ng mortar,
cement, concrete and the I i ke and thus have the possi bi I i ty of
correct i ng the posi ti on of the connect i ng devi ce without

I osses i n the strength of the connect i on between the two
components.
Thi s obj ect i s achi eyed by a system accordi ng to the i nventi on
and a met hod for produci ng a connect i on between two
components, one of whi ch consi sts of rei nf orced concrete,
concrete, mortar and the I i ke and a second consi sts of wood,
with the ai d of a system accordi ng to the i nventi on.
What i s proposed i s a connect i on system consi sti ng of at I east
two hol I ow bodi es made of metal or pl asti c, i n part i cul ar of a
tubul ar and/or rectangul ar shape, whi ch advantageously have a
corrugated outer surf ace and/or anchori ng el ements and/or a
rough outer surface, whi ch are sui tabl e for bei ng used i n a
formwork or the I i ke i nto whi ch concrete, rei nf orced concrete,
mortar or the I i ke i s poured. Advantageously, the hol I ow
bodi es al so have a corrugated/ rough i nner surf ace and/or
anchori ng el ements arranged on the i nner surf ace and/or a
rough surface. These hol I ow bodi es form the seat for i nserti ng
a base made of metal I i c mat eri al accordi ng to the i nventi on.
The base made of metal I i c mat eri al , whi ch i s connected i n a
preferred manner to a pl ate and/or an angl e, i s formed i n one
pi ece, the pl ate and/or angl e havi ng hol es or connect i ng
el ements for connect i ng the pl ate and/or the angl e to a second
wooden component on. The hol I ow body has a I arger hori zont al
cross sect i on, whi ch all ows the base i nserted i nto the hol I ow
body to be moved hori zont al I y by at least 10mm.
The hol I ow body can be open on both si des or one- si ded, e. g. a
tube cl osed by a lid and/or a casi ng.
Thi s all ows an easy posi ti oni ng and enough space to choose the
f i nal posi ti on of the bases.
The devi ce accordi ng to the i nventi on compri ses at I east two
bases, each of whi ch i s i nserted i nto a hol I ow body.

The met hod usi ng the devi ce accordi ng to the i nventi on
compri ses the foil owi ng steps of i nserti ng or pl aci ng an
el ement, whi ch consi sts of a hol I ow body with at I east one
openi ng, i nto a formwork. Advantageously, the openi ng can al so
be cl osed with a Ii d, whi ch can I at er be removed before
i nserti ng the base i nto the hol I ow body. Advantageously, t hi s
hol I ow body el ement has a corrugated and/or wri nkl ed outer
surf ace and/or anchor i ng el ements, whi ch enabl es a better
connect i on to the hardeni ng mat er i al , e.g. rei nf orced
lo concrete, concrete or si mi I ar, i nto whi ch it is i nserted.
Advantageously, t hi s el ement is a t ubul ar el ement, whi ch
advantageousl y has a cl osed bottom.
After inserting at least two hollow bodies and solidifying the
mat er i al around the hol I ow body, i n a second step at I east two
bases of the devi ce are each i nserted i nto a hol I ow body
accordi ng to the i nventi on.
Ina further step, the wooden wall i s pl aced on the pl ate
and/or the angle by pl aci ng level I i ng elements, e.g. wooden
bl ocks, between the wall and the concrete i nto whi ch the
hol I ow bodi es are i nserted.
Advantageously, the wooden wall i s posi ti oned agai nst the
vertical part of the plate and/or angle and placed on the
curved part of the plate and/or angle.
After the f i nal posi ti oni ng of the wooden part, it will be
fixed with the devi ce accordi ng to the i nventi on usi ng
f asteni ng el ements, e.g. screws or nail s. Ina further step,
the space between the base and the i nteri or of the hol I ow body
is fill ed with a hardeni ng mat er i al , e.g. B. cement mortar or
similar.
The i nner surf ace of the hol I ow body i s al so grooved and/or
provi ded with threads and/or f ol ds, whi ch enabl es a better
connect i on with the hardeni ng mat er i al i nt roduced.

The base i s connected to a pl ate or angl e or forms a si ngl e
el ement with openi ngs or connect i ng means to connect the pl ate
or angle to a wooden component.
After hardeni ng, I evel I i ng el ements such as wooden bl ocks are
removed and the gap i s advantageously fill ed with hardeni ng
materi al such as cement mortar or si mi I ar.
Accordi ng to the i nventi on, a kit i s al so proposed whi ch
compri ses at I east two hol I ow bodi es and a devi ce with a
corner/ pl ate with at least two bases for real i zi ng an

I n Fi gures la and lb, reference number 100 i ndi cat es a
connect i on system with a connect i on devi ce 110, whi ch connects
two components 200 and 201, of whi ch the f i rst component
consi sts of rei nforced concrete, concrete, mortar and the I i ke
and the second component 201 comprises at least one layer/part
made of wood.
Dun i ng its product i on, at I east two hol I ow bodi es 101 i n a
tubul ar and/or rectangul ar shape, whi ch can have a cl osed or
open bottom, are preferably i nserted i nto the f i rst component
200. I n one embodi ment, both si des may be cl osed, with one
si de bei ng cl osed by a removabl e I i d. The hol I ow body 101 has
at I east one openi ng at the top and i s preferably tubul ar. The
hol I ow body 101 preferably compri ses a corrugated and/or rough
outer surf ace and/or an outer surf ace with anchori ng el ements,
so that when the component 200 i s formed, for exampl e by means
of a hardeni ng mat eri al cast i ng, for exampl e made of concrete,
cement or the I i ke, the material embeds the hollow bodi es 101
and solidifies their embedding.
Advantageously, the i nner surf ace of the hol I ow body 101 i s
al so grooved and/or wri nkl ed and/or provi ded with anchori ng
el ement s.
The hol I ow body 101 has a hori zont al cross sect i on that i s at
least 10mm larger than the horizontal cross section of a part
of the base 102 that i s embedded i n the hol I ow body 101.
After rei nf orced concrete, concrete or the I i ke has
solidified, the hollow bodi es 101 accordi ng to the i nventi on
form the seat for one base 102, 122 of the connect i ng devi ce
110, 120. The bases 102, 122 can be i nserted i nto the hol I ow
bodi es 101 and moved so that the connect i ng devi ce 110 shown
CA 03231915 2024- 3- 14

i n Figures 2a and 2b can be posi ti oned to fi nd the fi nal
posi ti on of the connect i ng devi ce 110. Advantageously, the
bases 102, 122 al so have a corrugated and/or wri nkl ed outer
surf ace and/or anchor i ng el ements.
I n a second step, the base 102, 122, whi ch i s connected to,
for example, a T- shaped plate 124 and/or an angle 103, forms
the receptacl e for the component consi st i ng of at I east one
wooden part 201. The component 201 is connected to the
connect i ng devi ce 110, for exampl e by screws or by nail s
arranged on the plate or the angle 103. After attachment, the
component 201 comprises at least one wooden part. The
connect i ng devi ce 110 is placed i nto its fi nal posi ti on and
al i gned so that the second component 201 i s al so fi rml y
connected to the connect i ng devi ce 110. The connect i ng devi ce
110 has at I east two bases 102 whi ch are i nserted i nto two
different, spaced apart hol I ow bodi es 101.
Level I i ng el ements, e.g. wooden bl ocks are used to hol d the
second component i n posi ti on.
After posi ti oni ng the second component 201, a preferably
expansive hardeni ng compound 204, for exampl e cement, mortar,
concrete and the I i ke, i s i nt r oduced i nto the i nt er i or of the
hollow body 121 inside the hollow body 101 and thus fixes the
posi ti on of the connect i ng devi ce 110 and thus al so the
position of the second component 201, whi ch is at least
part i ally formed from wood mat er i al . Advantageously, the
cavity/gap 203 between the fi rst component 200 and the second
component 201 is al so fill ed usi ng filli ng material and the
connect i ng devi ce 110 after the I evel I i ng el ements have been
pull ed out, for exampl e with mortar, concrete, cement and the
like.
I n the embodi ment shown i n Fi gures 3a, 3b, 3c and 3d, the
connect i ng devi ce 110 has an angl e 103 connected to the base
102. The individual steps of the exemplary embodiment are

bei ng i nserted i nto a formwork in a fi rst step, whi ch i s shown
in FIG. 3d, and then fixed by pouring a hardening material,
such as mortar or si mi I ar.
I n Fi gure 3c, the devi ce 110 shown i n Fi gure 3a i s used.
Fi gure 3b shows the f i ni shed connect i on after the devi ce 110
has been attached to the wall 201 with nails and/or screws and
the gap between the f i rst component 200 and the second wooden
component has been filled with fill i ng material 204.
Fi gures 4a, 4b, 4c and 4d show a further exampl e of produci ng
a connect i on by means of a connect i ng devi ce 120, i n whi ch t he
connect i ng devi ce 130 has a T- shaped plate 123 whi ch is
connected to the base 122 and whi ch is i nserted i nto the
second component 201 with a correspondi ng seat.
i.s To connect the at least two components 200, 201 by means of
the connect i ng devi ce 110, 120 accordi ng to the i nventi on, the
f ol I owi ng met hod i s proposed, whi ch compri ses the f ol I owi ng
steps, the order of the steps bei ng abl e to be changed and

and or
f) filling the hollow bodies 101 with a hardening filling
mat er i al 204,
and or
f 1) posi ti oni ng the I evel I i ng el ements, preferably wooden

Accordi ng to the i nventi on, a kit i s al so proposed whi ch
i ncl udes at I east two t ubul ar or rectangul ar hol I ow bodi es 101
with an outer and i nner corrugated and/or f ol ded surf ace
and/or anchor i ng el ements, a connect i ng devi ce 110, 120 with
at I east two feet 102, 122 and hol e I ocati ons for i nserti ng
f asteni ng el ements, such as screws, nail s and pi ns.
An angl e 321 i s shown i n Fi gure 5a. Thi s angl e 321 can be
combi ned with a pl ate 322 whi ch i s provi ded with bases. The
combi nati on of an angl e 321 and a pl ate forms a connect i ng
devi ce 320. Thi s compound angl e 320 al so all ows for better
adj ustment on the constructi on site by all owi ng the posi ti on
of the bases to be adj usted rel at i ve to the verti cal surf ace
of the connector 320 agai nst whi ch the wooden component, such
as a wall , rests.

Fi gures 7a and 7b show how the connect i ng devi ce 320 can be
modi f i ed dependi ng on the component 201 with wood content and
al so dependi ng on the posi ti on and size of the f i rst component
200 made of concrete or similar and the position of the hollow
bodi es 101.
Figure 8a shows a further connection devi ce 340 for a further
embodi ment of the connect i on system accordi ng to the
i nventi on. The connect i ng devi ce 340 has at I east two bases
342. These bases are each i nserted i nto an i nteri or 121 of a
lo hol I ow body 101. Advantageously, these bases 342 have a f i nal
bend and hol es 343 at t hei r respective free ends, and the base
342 can al so have a long bend in the longitudinal direction.
These properti es ensure better stability of the foot and
better i ntegrati on i nto the filli ng materi al that fills the
space 121. The at I east two bases are connected to a pl ate 344
of the connect i ng devi ce 340, with whi ch a component 201 i s
connected to at least one wooden part/layer by screws and/or
nail s and advantageously al so forms the rebate for the second
component 201.
Numerous van i ants and suggest i ons can be provi ded for the
scope of protecti on of the subj ect matter accordi ng to the
