CONNECTION AND REINFORCEMENT SYSTEM FOR COLUMNS AND FLOORS MULTI-STOREY BUILDINGS It allows the construction of multi-storey buildings with a column-tofloor structure. Certified, calculated and optimised for glulam, LVL, steel and reinforced concrete columns. New architectural and structural horizons. COLUMN-TO-COLUMN The steel core of the system prevents the CLT panels from being crushed and allows more than 5000 kN of vertical load to be transferred between the columns. REINFORCEMENT SYSTEM FOR CLT The arms of the system ensure the punching shear reinforcement of the CLT panels, allowing exceptional shear strength values. Column spacing greater than 7,0 x 7,0 m structural mesh. CHARACTERISTICS FOCUS multi-storey buildings STRUCTURAL MESH Rk compression greater than 5000 kN VIDEO Scan the QR Code and watch the video on our YouTube channel MATERIAL S355-S690 zinc plated steel. FIELDS OF USE Multi-storey buildings with column-to-floor system. Solid timber, glulam, high density timber, CLT, LVL, steel and concrete columns. 292 | SPIDER | PANELS AND BUILDING JOINTS

WOODEN SKYCRAPERS Standard connection and reinforcement system to build wooden skyscrapers with column-to-floor system. New architectural possibilities in construction. CROSS CLT PANELS Exceptional strength and stiffness of the structure with crossed arrangement of the CLT floors. It is possible to create free spans greater than 6,0 x 6,0 m even without the use of moment joints. PANELS AND BUILDING JOINTS | SPIDER | 293

CODES AND DIMENSIONS SPIDER CONNECTOR Dtp ttp Dcyl tbp Dbp The code consists of the respective CLT panel thickness in mm (XXX = tCLT). SPI80MXXX for CLT panels with XXX = tCLT = 200 mm : code SPI80M200. CODE bottom plate SPI60S is supplied without top plate. This can be ordered separately with the code STP20020C. Also available for tCLT thickness values not shown in the table. Each code includes the following components: countersunk screw M16/M20 top plate (not included for SPI60SXXX) disc cylinder bottom plate 294 | SPIDER | PANELS AND BUILDING JOINTS

ASSEMBLY Fasten the bottom plate to the upper face of the column using the VGS Ø11 screws in accordance with the relevant installation instructions. It is possible to conceal the bottom plate in a grooving prepared in the column. For installation on steel columns it is possible to use M12 countersunk head bolts. Use suitable countersunk head connectors in case of installation on reinforced concrete columns. Fit the pre-drilled CLT panel with a circular hole of DCLT diameter onto the cylinder. A compression reinforcement can be provided to the panel bottom of beam to increase strength. Screw the...

ASSEMBLY Fasten the upper plate to the lower face of the column using the VGS Ø11 screws, in accordance with the relevant installation instructions. The top plate is equipped with suitable threaded holes for fastening to the hexagonal disc. Place the upper column on the hexagonal disc and fasten it using 4 SPBOLT1235 bolts with ULS125 washer. In the case of an upper steel column, the upper plate must not be used and the column must be equipped with a suitable steel plate with holes for fastening the 4 SPBOLT1235 bolts. The slotted holes in the hexagonal disc allow the column to be rotated ±5°....

For SPIDER connectors with cylinder diameter Dcyl = 100 or 120 mm, the hexagonal disc dimension is increased. In this case, the phase 6A must be replaced with phases 6B - 6F . After inserting the hexagonal disc and countersunk head screw, insert 12 HBSP8120 screws into the 12 vertical holes provided in the 6 arms. These screws will hold the arms in place in the following phases. Unscrew the countersunk head screw and remove the hexagonal disc. With a NON-PULSE screwdriver, insert the 12 VGS Ø9 screws inside the inclined washers closest to the cylinder, respecting the 45° insertion angle (if necessary...

CLT PANEL PRODUCTION AND INSTALLATION TOLERANCES The connector is designed to adapt to CLT panel production and installation tolerances. The actual thickness of CLT panels may be slightly different from the nominal thickness due to a production tolerance. 1. PRODUCTION TOLERANCE ON CLT PANEL THICKNESS of ±2 mm The cone must be screwed until it touches the surface of the CLT panel (surface way to ensure contact with the cylinder (surface A ). The tolerance of ±2 mm is absorbed in the area - ), while the disc must be installed in contact between disc and arm in the area joint of 2 mm in the area...
