Steel bearings

PFEIFER Steel Bearings absorb theintegral weight loads during the instal-lation of TT-beams. Together with theinserted reinforcement and the pou-red-in-place layer of concrete, trafficloads are safely and reliably divertedinto the ceiling joists. The overallload-bearing structure can be plannedand calculated much more easily andconstructed without bracket consolestrip supporting joists.

The lower building heights and cleanbottom views of the ceilings have apositive impact on the general appea-rance of the building.

Just 3 types of steel bearing are re-quired to cover the full range of TT-beams with span widths of up to25 m.

Ceiling joists5) and trough plates5) canalso be supported quickly and cost-effectively.

Material:Rolled steel S 355Concrete steel BSt 500S, forgedPrecision steel pipeSpot-welded support plate

All welding work is performed inaccordance with the full-scale certi-ficate of welding competence accor-ding to DIN 18800 and the weldingsuitability certificate according toDIN 4099

1 Basis for calculations:DIN 1045-1 July 2001edition DIN 18800 November 1990 edition

2 MaterialsConstruction steel: S 355, S 235Concrete steel: BSt 500 S(A), BSt 500 S(B)Concrete for precast parts: TT plate at least C35/45 (the concrete of the

precast part must be fully hardened at the startof construction).Load-bearing components (ceiling joist / wall)at least C25/30 or at least the concrete qualityof the concrete topping.

Concrete topping: Concrete strength classes C20/25 to C30/37.See dimensioning tables.

3 Loads:Predominantly static in accordance with DIN 1055-3 / 3.2.1.Additional structural calculations and verification are required if the loadsare not predominantly static in accordance with DIN 1055-3 / 3.2.2.

4 Loads on the poured-in-place concrete floor during construction siteoperations:Prerequisite: minimum strength of the young concrete at least 40% of fck ofthe concrete topping.Without more accurate calculations, the average traffic load constructionsite operation must not exceed a value of qk = 1.00 kN/m2.

5 Fire resistance:The steel bearing structure complies with fire resistance class F120 inaccordance with DIN 4102, part 2, provided the component itself complieswith this classification in accordance with DIN 4102, part 4. DIN 4102, part4, section 3.2.4.8 must be observed. The required concrete covering of theanchor plate must also be taken into account.

6 Exposition classesFor the structural type calculations, the exposition classes XC1 – XC3 areused in accordance with DIN 1045-1, Table 3, as the basis for calculationsof reinforcement corrosion. If exposition classes with more far-reachingrequirements in terms of the minimum concrete strength classification orthe minimum concrete covering thickness are present then additional calcu-lations and verifications may be required.It may be necessary to additionally coat the underside of the steel bearingswith a layer of anti-corrosion protection. In this case the planned concretethickness is 15 mm.

7 General notes:The definitions in DIN 1045-1, DIN 1045-2 and DIN 1045-3 must be takeninto account in relation to the installation and location of the reinforcement.The composition of the concrete (maximum grain diameter of the mineralaggregate dg) may need to be matched to the present separation/spacing inany given case.

8 Other calculations and verifications:The precast parts themselves and the transmission of forces both need tobe verified with separate calculations for every individual case.

1) Calculated horizontal force due to constraint: HRd = 0.20 x VRd, total

2) Intermediate values can be calculated by linear extrapolation.3) Alternatively, you can also opt for thinner rod diameters with an overall equal or greater concrete steel cross-section.4) Refer to the “General technical application criteria” on page 6/7 for information about the layout and design of the mounting reinforcement.5) During construction, the partial safety factor of the influences must not be reduced. The own weight should always be based on γG = 1.35.

Installation instructionsAs the PFEIFER steel bearing and the associated tensile rod are suppliedloose (this takes up less space in transit), the connecting rod with plateneeds to be screwed into the sleeve of the steel support with a torquewrench before installation (e.g. using a PFEIFER torque wrench) (see Fig.1). Please observe the tightening torques in Table 1 when doing this. Onthin components the plates of the anchoring bar should be aligned parallelto the steel profile. To do this, the anchoring rods can be turned backaccordingly by up to a quarter of a turn.

The PFEIFER steel bearing (with screwed-in tensile rod) can be embeddedwith wire in the reinforcement cage which is to be constructed (see Fig.2). However, the steel bearing should not be fastened too tightly to thereinforcement cage in order to enable subsequent adjustments.

The mounting of the PFEIFER steel bearing can be performed using thefollowing methods:• bearing plate welded onto the steel formwork (Fig. 3)• wooden structure on the steel formwork (Fig. 4)• bearing plate attached to the steel formwork using magnet technology.

The steel bearings which are still movably attached in the reinforcementcage are then aligned in the longitudinal and lateral directions of the TT-beam (Fig. 5) and secured onto the bearing structure using a clampingdevice (e.g. Figs. 3 to 4).

In order to correctly position the horizontal concrete steel reinforcementswhich lie to the left and right of the PFEIFER steel bearing, correspondingcutouts are provided in the formwork (rake, Figs. 6 and 7). The gapsabove the rake can be closed off and sealed with polystyrene.

The mounting reinforcement should be installed with great care in accor-dance with the drawing on page 6. During installation of the reinforce-ment, the rulings contained in DIN 1045-1 must also be satisfied. Thecompleted reinforcement cages including PFEIFER steel bearings can thenbe lifted into the prepared TT-beam formwork.

After concreting, the horizontal concrete steel reinforcement outside theprecast element and the vertical hoop above the steel support must beclearly exposed (with no concrete residue in between) in order to obtain a good bond with the layer of poured-in-place concrete which is subse-quently cast (Fig. 8).

During installation of the precast TT-plate at the construction site, caremust be taken to ensure that the gap between the level surface of the TT-plate (Fig. 9) and the ceiling joist is closed, e.g. by means of a pre-com-pressed strip, in order to prevent escape of the cement paste during con-creting of the layer of poured-in-place concrete. The dimensions andinter-component gaps shown in Fig. 9 are obtained when the steel bearingis used. Wherever the steel bearings come to rest, the hoops in the ceilingjoists must be appropriately arranged order to enable the TT-plates to belaid with the above bearings and the lateral concrete steel reinforcement,as seen at the bottom of the picture on page 3.
