The function-related instructions in this brochure must be accurately followed. Deviations from these require a separate proof of structural strength. To ensure the safe use of our products, all the relevant safety rules and regulations of the national accident insurance institutions and public authorities must be complied with. As a fundamental principle, only materials in immaculate condition may be used. Damaged components must be taken out of circulation. As replacement parts for repairs, only original parts from Thyssen Hünnebeck Schalung GmbH may be used. The combined use of our formwork system with equipment from other suppliers may entail certain dangers and therefore requires additional checks. The illustrations in these assembly instructions must be regarded as examples. It goes without saying that the regulations for occupational safety must be adhered to. We explicitly reserve the right to make changes in the service of technical progress. Rasto is a frame formwork system which can be used without a crane (manual shuttering) or shifted in large units by a crane. For element widths up to 90 cm it is not absolutely necessary to have a crane on site. However, the use of the large Rasto XXL panel or the simultaneous transfer of several panels is only possible by crane. Rasto formwork is a frame formwork system with a hot-dip galvanized steel frame and an integrated 14 mm thick, high-grade shuttering skin. The maximum permitted concrete pressure is 60 kn/m² for single-tier and 55 kn/m² for height-extended forms. As the panels are available in 9 different sizes, ranging from cm to max. 240 cm, Rasto is easy to adapt to any building shape. The three element heights of, and 0 cm make it possible to adapt the formwork easily to different heights. The 120 cm Takko form, which has an identical design, is a useful supplementary element. The Rasto aligning clamp as the connector joins the formwork elements to form a tight, tension-resistant and aligned joint. This applies both to the vertical and to the horizontal butt joints on height-extended elements. The vibration-resistant joint also permits large-area handling by crane.

11 Element connection If height-extended 3.0 m tall Rasto panels or horizontal height-extension elements are used, the longer adjustable clamp connects the elements on the horizontal joint. Rasto aligning clamp on a vertical panel joint Thanks to its greater length, the adjustable clamp achieves good alignment even in this arrangement as it is braced against the panel s ribs. Rasto aligning clamp on a horizontal panel joint /0 Adjustable clamp Horizontal panel(s) -90 The Rasto formwork panels are connected with the Rasto aligning clamp. This connector creates tension-resistant, tight and aligned joints between formwork elements. It can be used both on vertical panel joints and on horizontal joints on height-extended formwork. 0 All Rasto connectors require nothing more than a carpenter`s hammer. Instead of being used to strike the connectors, the pointed end of the hammer is inserted into the screw head like a spanner. This method is laboursaving, gentle to materials and quiet.

16 Tying Rasto formwork is tied via the tie holes provided in the panels. Before insertion of the tie rod, the plug must be removed. Unused tie holes should be sealed with plugs. Rasto panel Plug On foundations it is often difficult to tie the formwork in the building pit. The solution with the FU tightener and the punched steel tape represents a sensible alternative. The punched steel tape supplied in a continuous length is cut to size and laid beneath the horizontal Rasto panel. The FU tighteners are inserted into the ribs of the horizontal Rasto panels. The finger of the FU tightener is inserted into a hole of the tape and the formwork is adjusted with the threaded bolt. The edge tie fastener MR positions the top tie above the Rasto panel. This means that it is easy to fit and remove and can be positioned independently of the hole module. Detail of Edge tie fastener MR When tying the panel joint, the tie plate (13 cm dia) of the Manto tie nut extends across sufficiently to the neighbouring panel. Edge tie fastener MR If length adjustment pieces are used, tying is always effected through the adjustment piece. For adjustment widths > 8 cm, the tie loads are discharged via the large plate of tie nut 2. Tie nut 2 22 Length adjustment > m with 90 cm formwork height Punched steel tape FU tightener For both types of tie (steel tape and edge tie fastener MR) the maximum permitted loading is 10 kn. For 90 cm high foundations, this means a distance between ties of 1.75 m.

17 Corners The inner corner of Rasto formwork, with the patented 2 of stripping clearance, has a leg length of cm. The inbuilt corner stiffener ensures that the inner corner forms an exact right angle for concreting. Corner stiffener By simply disengaging the corner stiffener, the 90 angle can be eased by 2. It is then possible to remove the inner corner from the concrete without difficulty. First panel joint of the outer corner Rasto panel Rasto panel Outer corner clamp 2 The right-angled outer corner is always composed of two Rasto panels aligned and held together with outer corner clamps. The formwork can be adapted to wall thickness with the available elements of to 90 cm and the 5 cm adjustment piece. The number and arrangement of outer corner clamps and of the Rasto clamps on the first joint of the outer corner depends on the thickness and height of the wall being shuttered. See the table on page 19. Corner stiffener disengaged Rasto Formwork Instructions for Assembly and Use 17

18 Arrangement of Rasto panels for wall thicknesses of 15 to 50 cm in 5 cm increments 5 By using the 5 cm adjustment pieces it is possible to bridge gaps in the module of panel widths. Adjustment pieces in the panel joint (inside or outside) demand the use of the adjustable aligning clamp as the connector cm 15 cm cm 20 cm cm 25 cm cm cm Adjustable aligning clamp 5cmadjustment piece The adjustability of the corner clamp also makes it possible to fit adjustment pieces in the joint of the outer corner cm 35 cm cm 45 cm cm cm 50 cm Outer corner clamp 5cmadjustment piece System dimensions of the Rasto corner For corners with different wall thicknesses, the same principles should be applied to panel arrangement.

20 Wall T-junctions Stopends At wall T-junctions, system shuttering can be simply used up to a wall thickness of 40 cm. Adaptation is possible with the various panel widths and the 5 cm wide corner adjustment piece. The holes in the edge profiles of Rasto panels provide fastening means for stopends. By using the centering tension bolt and centering nut (or tension nut), the waler 80 or a correctly dimensioned piece of squared timber, for example, can be used to accommodate the stopend. Stopend Waler 80 Centering tension bolt and centering nut For wall thicknesses > cm, at least 3 waler profiles must be fitted for a wall height of 2.7 m > cm Centering tension bolt Corner adjustment piece Waler 80 Rasto Formwork Instructions for Assembly and Use 20

21 Length adjustment Adjustment to the required formwork length is effected by combining the various panel widths. Gaps in the module of the panel widths 15 cm are bridged with a length adjustment piece positioned between the panels. Gaps up to 15 cm are bridged with the aid of 12 cm thick timber adjustment pieces. The ties must always be inserted through the adjustment piece. The panels are given tension- and compression-resistant joints with the adjustable clamp. For larger adjustment widths up to cm, use the waler 80. It should be fastened to the perforated ribs of the Rasto panels with 2 waler spanners (and tension nuts) in each case. Tying is also effected here through the adjustment piece. max. cm 12 cm Adjustable aligning clamp (adjustable from 1-15 cm) Timber adjustment piece (12 cm thick) max.15 cm The timber adjustment pieces to be provided on site (10 cm thick squared timbers + 21 mm thick shuttering skin) can be nailed on via the holes 1 in the waler. 21 mm shuttering skin Tie nut 2 8/10 or 10/10 squared timber When tying, make sure that the tie nut is sufficiently supported on the edge profiles of adjacent Rasto panels. For adjustments greater than 8 cm wide, the tie nut 2 with the large bearing plate should therefore be used. Nail Waler spanner Tie Rasto Formwork Instructions for Assembly and Use 21

22 Corners with oblique angles With the two hinged corners 15 and offered by the Rasto system, it is also possible to shutter non-rightangled (oblique-angled) building corners. They differ in their leg lengths (15 or cm) and in their possible adjustment ranges. Hinged corner can only be used as an inner corner. On corners greater than 90, the MP-panels in the outer formwork make tying easier. Hinged corner 15 MP-panel Hinged corner max. min.60 The formwork example shows a combination of hinged corner as the inner corner with a hinged corner 15 as the outer corner.

24 Column formwork with MP-panels The MP (multi-purpose) panel with the continuous row of holes on the tying levels are used amongst other things as column formwork. Four of these MP-panels, assembled in the manner depicted, create a variable form for square and rectangular columns. It can be adjusted in a 5 cm module from 15 cm to max. 55 cm. min.15 cm max.55 cm Column formwork with Rasto panels A column form made of standard Rasto formwork panels can be simply and quickly assembled for a wide range of dimensions with the aid of the outer corner clamp. By arranging the panels in pairs or offset, or by using an adjustment piece at the panel overlap, the form can yield column cross sections ranging in size from 20 cm to 85 cm max. The number of corner clamps required depends on the form height and the width of the Rasto panels employed (see table). Panels in pairs Panels offset Number of corner clamps Form height Panel width < 60cm > 60cm 1.50 m 2.70 m 3.00* m 3x4 4x4 5x4 3x4 5x4 6x4 * Maximum form height Outer corner clamp The connection Manto tie nut Panels offset 80 (85) 65 (70) 55 (60) 50 (55) 45 (50) 40 (45) 35 (40) MP-bolt MP-nut (...) with the use of a 5 cm corner adjustment piece Panels in pairs 70 (75+80) Panel (60+65) Panel (50+55) Panel (45+50) Panel (40+45) Panel 55 (35+40) Panel (+35) Panel Panels in pairs Adjustable aligning clamp On height-extended column formwork with panels of different sizes, the smaller panel should always be at the bottom. The adjustable clamp is used as the connector. The use of a 5 cm corner adjustment piece (or a different 5 cm wide infill piece) in the corner is another means of adjustment.

25 Brackets and struts The walkway bracket is simply hooked into the holes of the Rasto panel ribs. The spring pins permanently attached to the bracket prevent it from being accidentally lifted out. The scaffold planking must be secured by means of the integrated wooden strip. The inserted railing posts create a 1.2 m high guard rail. The R-adjusting strut aligns and secures single-storey Rasto formwork (up to a form height of < 3.0 m). It comes with all the connecting pieces and is usually connected to the edge profiles of the panel joints. The formwork is aligned with the two tension- and compression-resistant spindles. Panel joint 1.00 m TK railing post 1.20 m R-adjusting strut Walkway bracket If connected to a horizontal Rasto panel, the waler bolt D20 has to be fitted and is also secured with the spring pin. For formwork heights < 3.0 m, the distance between R-adjusting struts must not exceed 2.25 m. Waler bolt D20 Waler 80 Waler spanner R-adjusting strut Spring pin The maximum permitted horizontal distance between walkway brackets is 2.5 m (or 1.9 m for applications > m above the ground). It is designed for the loads of scaffold class 2 to DIN 4420, Part 1, edition 12/90 ( kg/m²). In exceptional cases (e.g. for column formwork), it may be necessary to connect the R adjusting strut in the interior of the panel. By using waler 80, which is fastened with 2 waler spanners (+ 2 tension nuts) to the ribs, it is possible to connect both the adjusting strut and the strut connector.

26 To provide additional support to height-extended Rasto forms and for form heights > 3.0 m, the R-strut connector and the strut base joint permit the use of standard tubular steel props for this application An additional counter nut gives the tubular steel prop a tension- and compression-resistant joint. Counter nut Tubular steel prop adjustment range 35 6 The choice of tubular steel prop depends on the load, form height and the associated extension length. The Thyssen Hünnebeck range of props covers all lengths from 1.5 to 5.5 m (see loading table for tubular steel props). Important! The maximum permitted tensile loading of the tubular steel prop is always at least 15 kn. R-strut connector * = 4 hexagon bolts and nuts M 12 x Tubular steel prop * = 4 hexagon bolts and nuts M 12 x Strut base joint 21dia. 18dia. The holes of the connection plate of the R-strut connector permits the connection* of all Thyssen Hünnebeck tubular steel props. In special cases, it is also possible to connect Alu-Top props or BKS aligning struts. The fully assembled support is connected, as illustrated, to the panel joint of the Rasto form. The base plate of the strut base joint (like that of the R-adjusting strut) has 2 holes for attachment to the foundation slab. Rasto Formwork Instructions for Assembly and Use 26

27 Handling large-area formwork units with a crane For the crane handling of large-area Rasto units, only the RT crane hook must be used. This hook must always be used in pairs and has a maximum load-bearing capacity of 500 kg. In this way, formwork units of up to 25 m²(*) can be shifted with a single pair of hooks. Connected RT crane hook. Caution! The pin must be inserted as far as the stop. Angle of spread of crane ropes > 60 On the Rasto XXL panel, the connection point for the crane hook for individual panel handling is in the corner at the rail profiles. Units for crane handling must not comprise more than 3 Rasto XXL panels. Connection to a vertical Rasto XXL panel (*) = Units including the XXL panel must not exceed 20 m²of Rasto formwork The RT crane hook must always be connected to a panel joint. With the fastening pin withdrawn, the hook is guided over the panel edge profiles and aligned with the top hole. When the fastening pin is fully inserted, the RT crane hook is ready for use. RT crane hook Panel joint Top hole in edge profile Connection to a horizontal Rasto XXL panel With drawn fastening pin Always heed the following points: Always use RT crane hooks in pairs. Insert the fastening pins as far as the stop. The angle of spread between crane ropes must not exceed 60. Only use materials in immaculate condition. Do not exceed the maximum loading.
