Since 1987, Buzon Pedestal International has been Europe's leading manufacturer of screwjack polypropylene pedestals. The reputation of BUZON® pedestals is the fruit of extensive experience and a willingness to satisfy the exacting demands of Architects, Specifiers, quantity surveyors and construction professionals, offering a wealth of construction and technical information. Our team of designers and engineers are ready to give you immediate support for your projects and construction sites all over the world.
For exterior and interior locations, commercial, industrial installations such as food storage; where regular cleaning and drainage is required. At roof level, pedestals can be used to support decking or pavers to contain and protect the services for ventilation, water supply and lighting. Services running in cavity below can be easily accessed.
Pedestal spacing options allow for complex layouts, abutments, penetrations and edge details. Typical application types include: raised access decks at ground or roof level for commercial and other sectors; support for visible bottom surface of water features over service voids; industrial floors using grid systems; temporary exhibitions, podiums, plinths and raised false floors.

2. Compliance:

** NOTE TO SPECIFIER ** Loading Test Positions: The following loading data for pedestals with loads applied at various positions on the load bearing top surface of the pedestals. 1/1 is load evenly applied across entirety of the load- bearing surface; 1/2 is load applied to half of the load- bearing surface; 1/4 is load applied to one quarter of the load-bearing surface. The tests were carried out on a universal testing machine, type Instron 1185 n degrees H - 4573, with a capacity of 100 kN, fitted with a 100 kN force transducer No. 2518 - 201. The loading speed was 10 mm/min. The mean RUPTURE value, expressed in daN or en lbf, is the result of carrying out the test on 3 supports at different heights. If any option other than ' Standard, talc-loaded...' is selected above for ' Pedestal Component Materials' then delete data listed under ' Configuration' for ' Loading Data.'
a.Testing Agency: Belgium (CRIF) Centre De Recherches Scientifiques ET Techniques Del Industrie Des Fabrications.

1. Composition: Five piece, interlocking, multi-threaded unit consisting of slope corrector, mounting head, height extension coupler, adjustment ring clamp coupler, and support base.

a. Slope Corrector: Slope compensation system, adjustable in increments of 0.5% up to a maximum 5% slope. Slope corrector is mounted to the pedestal head with fixing clips, and is formed from two cylindrical parts that allows compensating for 1 to 5% slopes to provide a level mounting head; 255mm (10 inch) diameter; 12mm (1/2 inch) thickness to be added to the adjustable height of the pedestal.

b. Pedestal Head: Large support surface with reinforcement ribs; screwed directly into the coupler or adjustment ring clamp; fitted with slots to receive cylindrical plate with 4 paver positioning blades of various thicknesses to achieve an open gap between pavers. Including locking safety clips to prevent total unscrewing of the pedestal head.

c. Height Extension Coupler: One-piece extension coupler with upper part threaded to receive additional extension couplers or the pedestal head, and lower part threaded to screw into the adjustment ring clamp coupler. Including safety clips to prevent total unscrewing of the pedestal head or ring clamp. Lock keys keep the pedestal height in place after height adjustment.

d. Adjustment Ring Clamp Coupler: Factory assembled ring clamp coupler, factory fitted onto the support base; ring clamp consists of reverse threading cylinders with multiple inner and outer threads, and fitted with safety locks to prevent total unscrewing of the components.

e. Support Base: Cylindrical support base with reinforcement ribs, threaded to receive ring clamp coupler. Support base can be placed or fixed to a solid substrate, or partially cut away for positioning against a wall. Includes holes at bottom for drainage.

2. Height Range: Fix (17 mm; 21/32 inch) and (28mm;1 3/32 inch) or infinitely adjustable by rotation of each pedestal component, using variable height support bases ranging from 17 to 175mm (5/8 to 6- 7/8 inch), and multiple height extension couplers up to a maximum height of 1073 mm (42 1/8 inch).

3. Material: Ultraviolet (UV) stabilized, talc-filled, high density, copolymer polypropylene, weather, sea salt, and chemical resistant; 3 to 4.5mm (1/8 to 3/16 inch) thickness.

4. Temperature Range: Resistant from -30 degrees C to 90 degrees C (-22 degrees F to 194 degrees F).

C. Mounting Head Accessories: Spacer tabs, rubber shims and mounting plates with paver positioning blades, support pins, and joist supports that can be clipped to the head of the pedestal to accommodate the selected roof decking material.

D. Perimeter Containment And Support

1. The complete assembly of roof decking pedestals and pavers shall be restrained at the perimeter of the walk deck area to resist lateral movement. 3mm standard allowed at all edges, total 6mm allowed max.

2. Cumulative movement in excess of 6 mm (1/4 inch) will void the manufacturer's warranty.
