Design Manual connectors



A/ HVP concealed connectors1. General pointsPitzl HVP connectors are two-piece,face-fixed beam hangers for connections of joist to header (beam or column).

The load-carrying capacity of the Pitzl HVP connectors is determined by calculation assisted by tests.

In the following formulas are given to calculate the load-carrying ca-pacities according to the European Technical Approval ETA-11/0295.

Thanks to a timber or wood-based panel protection on all sides the Pitzl HVP connectors can verify a fire resistance up to 60min.The cal-culation concept is to find in Part 4,such as in the European Technical Approval ETA-11/0295.

For typical material combinations and geometry the characteristic load-carrying capacity is given in the tables of the Part 5 for Spax screws.

Pitzl HVP connectors can as well be used with screws from other manufacturers.Tables with load-carrying capacities for other screws are available on demand.

2. Design conceptPitzl HVP connectors shall be designed according to Eurocode 5 or a similar national Timber Code.The following formulas were deter-mined taking account of the European norm Eurocode 5: Design of timber structures (EN 1995-1-1) and take also into considera-tion the current state of technical development in terms of safety concept,dimensioning and design.

On the action side the characteristic loads are increased by the safety partial coefficients (G = 1,35 for permanent actions, Q= 1,5 for variable actions).

Whereas on the resistance side the characteristic load-carrying capaci-ties are reduced by division with the partial coefficient M.

For wood-based materials the influence of the service class and the load-duration class is additionally to take into account by the modifi-cation coefficient kmod.

3. FormulasIn the following formulas are given to calculate the load-carrying capacities,such as they are also to find in the European Technical Approval ETA-11/0295. So the load-carrying capacity of the connec-tion can be calculated depending on the load-carrying capacity of the chosen wood-based material, such as the connection geometry (inclined joist).

Pitzl HVP connectors are designed for use in service classes 1 and 2.

The load-carrying capacities are given for loads in the direction of insertion (F2),against the direction of insertion (F3) and perpendicu-lar to the direction of insertion (F4) as well as perpendicular to the connector plane (F1).

The force in the direction of insertion (F2),the force against the direc-tion of insertion (F3) and the force perpendicular to connector plane (F1) are supposed to act in the joist axis.

The torsion moment from the joist connection must be taken into account for the design and the storage of the header.

The verification of the connection of the HVP connector to concrete or steel elements must be led with the given shear force.

The given load-carrying capacities are valid on the condition that all designed fasteners are built in.The header connections to concrete or steel elements must be built with at least 2 fasteners in the upper holes.

In the following are given characteristic load-carrying capacities for a connection where the joist beam is horizontally and vertically perpen-dicular to the header beam for definite material combinations.

As fasteners are used full threaded Spax-screws made of carbon steel with countersunk head according to ETA-12/0114.

Their dimensions and the wood-based materials with them they are used are as below:

4,5 x 50 mm or 4.5 x 60 mm (HVP 8045 and 8075) 5 x 60 mm or 5 x 80 (or 70) mm (HVP 8160 to 8320) in timber elements classified C24 or GL24h

8 x 160 mm or 8 x 180 mm or 8 x 120 mm in timber elements classified GL24h or GL28h.

NB:

Tables of load-carrying capacity for screws from other manufacturers are available on demand.

Pitzl HVP connectors are designed for use in service classes 1 and 2

The load-carrying capacities are given for loads in the direction of insertion (F2),against the direction of insertion (F3) and perpendicu-lar to the direction of insertion (F4) as well as perpendicular to the connector plane (F1).

The force in the direction of insertion (F2),the force against the direc-tion of insertion (F3) and the force perpendicular to connector plane (F1) are supposed to act in the joist axis.

The torsion moment from the joist connection has to be taken into account for the design and the storage of the header.

If the HVP connector is connected to concrete or steel elements,the load-carrying capacity of the header metal anchors or screws shall be additionally verified (cf.Part 3.3).The connection to concrete or steel elements must be built with at least 2 fasteners in the upper holes.

The given load-carrying capacities are valid on the condition that all designed fasteners are built in.

Wood-based materials:

Solid timber classified C24 minimum according to EN 338:2010-02,

Glued laminated timber classified GL24h or GL28h minimum according to EN 1194:1999-05

DIN18800




The eccentricities e2 and e45 for the determination of the load-carrying capacity in the direction of insertion (F2) and the load-carrying capa-city perpendicular to the direction of insertion (F4) are assumed as follows: e2 elim and e45= 0.If the force (F2) acts with an eccentricity e2 > elim,the load-carrying capacity is to calculate according to the formula (9) (cf.Part 3.2).

If the force (F4) does not act in the centre of the HVP connector (for example,for a front transom) with an eccentricity e2 > elim, the load-carrying capacity is to calculate according to the formula (12) (cf.Part 3.2).

For this the load-carrying capacities of the single screws according to Table 2 can be used.

The combinations 5 and 6 allow to reduce the minimal timber sec-tions (cf.Minimal timber sections).

The both upper inclined screws of the header plate and the both lower inclined screws of the joist plate are 120mm long.

6. Timber dimensions6.1. Minimal timber dimensions and distances to the edgesJoist horizontally and vertically perpendicular to header:

In the following the minimal timber dimensions and distances to the edges are given for a connection with Spax screws of different lengths where the joist is horizontally and vertically perpendicular to the header.

The minimal timber dimensions and distances to the edges are valid for the HVP connectors 8045 to 8320 for a loading in the direction of insertion (F2).

For the HVP connectors high loads (8420 to 8460) they are valid for the loadings: in the direction of insertion (F2) and perpendicular to connector plane (F1).

For other loadings and connection geometries the indications of the screws manufacturer and of the page 23 must be respected.

7. Connections to concreteThe load-carrying capacity of the concrete part (anchors and concrete) and the distance between the anchors and the edges must be calcula-ted according to the corresponding current standards.

Fasteners of the concrete part per HVP connector:HVP 8211B to 8320B:

4 x 12 mm high performance anchors with countersunk head,for example Fischer FH II 12/15 SKHVP 8420B to 8440B:

4 x internal threaded anchors M12,for example Fischer RG 18 x 125 M 12 I

4 x screws with countersunk head M 12,steel quality 8.8 (inclusive in the delivery content)HVP 8445B to 8460B:

6 x internal threaded anchors with M12 (or M16 according to static requirement),for example Fischer RG 18 x 125 M 12 I

6 x screws with countersunk head M12 (or M16 according to static requirement),steel quality 8.8 (inclusive in the delivery content)

The header-plates of HVP 8445 to 8460 comprise injection drilled holes in order to fill the gap between the screws and the connector-plate and thus ensure an equal and simultaneous loading transmission of all screws and screw anchors.

NB:

HVP 8425B, 8435B, 8445B, 8450B, 8455B und 8460B are no carry articles.

Construction:

The construction instructions of the anchors manufacturer must be observed.

The anchors with internal screw thread can be fixed either with boreholes in the concrete wall and injection mortar or by embedded anchor plates in concrete.

Anchor plates with welded internal threaded anchors ensure a precise and quick fixation of the HVP connectors.

By the way the distances to the concrete edges can be reduced.

These anchor plates will be manufactured according to your requirement (structural engineering calculation).

EH,d Design value of stress in the load cases H1 or H2 in N

RH,d Design value of load-carrying capacity in the load cases H1 or H2 in N

Increase of the tension load-carrying capacity:

The load-carrying capacity of the fasteners in timber was calculated for screws with a thread length of 100mm.

By use of screws with longer thread lengths the tension load-carrying capacity can be calculated with the following equation:

and
