EFFICIENT TIMBER JOINTS:
No slitting and tapping - the BiLO ® -UBt-connector connects timber joints
of solid wood and wood material quickly and invisibly.
BiLO ® -UBt-connectors are manufactured of 4 mm thick steel and are
galvanized all-around.
The BiLO ® -UBt-connector is marked by numerous application options
at a high flexibility in planning and the design of wood structures.
The wide-range selection of the connector sizes allows the optimal
implementation of all connections in static wood construction.
The invisible use of the connectors enables clean component connecting
joints, which meet the highest aesthetic demands.
The BiLO ® -UBt-connector can support loads in hanging direction
(symmetric axis) lateral to the hanging direction as well as tensile forces.
Forces against the slide-in direction (such as lifting forces) can be absorbed
in conjunction with the BiRA ® -HK-screw connector. The simple, filed
plug-in system of the BiLO ® -UBt-connectors provides the employee with
great potential cost-reductions.

BiLO ® -UBt-connector:

• A hole of diameter 5 mm is introduced in the direction of the upper edge of
the secondary beam to precisely position the BiLO ® -HK-screw connector
by the longitudinal hole of the assembled BiLO ® -Ubt-connector on the
secondary beam below an angle of ≤ 80°. The focus of the bolted part
attached in the secondary beam should equal 10 d1 from the end of the
secondary beam according to appendix 10 of the permit.
• Based on pre-drilling, the load of the BiLO ® -HK-screw connector is reduced
by 10% against extracting (authorized Nz i.e. Rax,k) (see Z-9.1-667).

In (horizontal) slanted (30° ≤ a < 90°) or (vertical) inclined (30° ≤ b < 90°) connections, the values Q i,k and/or Q r,k must be multiplied by
factor ks = [ ( 1-sin5 (90° - a)) x ( 1-sin3 (90° - b) ] m . (m = 0,5 bzw. 0,7 depending on the positioning of the main beam).
(e.g.: a = 60°, b = 45°, m = 0,7 ks = [ 0,969 x 0,646 ] 0,7 = 0,720).
2) Values only apply for a single load from Q i,k oder Q r,k oder Z k (Load combinations and planned momentum effect are regulated in the
permit by additional verifications).
3) Table values Q i,k bzw. Q r,k must be multiplied by 0.8, if the main beam and/or support or wall cannot freely turn (or slope accordingly)
and via timbered joints and grain-cut timber - grain-cut timber connection for load reductions.

Building-inspection approved under No.: Z-9.1-667
BiRA ® -HK-screw connectors were developed for the structural timber
construction. They are used to deflect lifting forces in conjunction with the
BiLO ® -UBt-connector (forces against the inserting direction).
A hole of diameter 5 mm is introduced in the direction of the upper edge of
the secondary beam to precisely position the BiLO ® -HK-screw connector
through the longitudinal hole of the assembled BiLO ® -Ubt-connector on the
secondary beam below an angle of ≤ 80°.
The BiRA ® -HK-screw connector is bolted in effortlessly and precise after
attaching the secondary beam through the hole at the desired length.

Advantages of the BiLO ® -UBt-connectors:
1). Invisible connection.
2). Easy and powerful plug-in connection.
3). Load reduction of lateral forces (Q i,k ) in the inserting direction and
laterally toward the inserting direction (Q r,k ) as well as tensile
forces (Z k ).
4). Load reduction of suction forces (against the inserting direction)
in conjunction with BiRA ® -HK-screw connectors (Z-9.1-667).
5). No gap formation.
6). Reduction of the assembly time as well as a calculation advantage.
7). Great pre-manufacturing standard.
8). Usable for timber cross-sections from 64 / 90 mm.
9). Quick and easy assembly.
10). Low sinking depth of 8.5 - 9.0 mm. The cross-section reduction
is generally negligible.
11). Connections of various material combinations
(e.g. solid wood materials).
12). Time-saving and efficient assembly of pre-manufactured
complete elements.
