Production in the factory

Precast concrete elements for structural engineering are efficiently produced with consistent quality at the precast concrete factory. Paul provides advice and supplies casting bed equipment for beams, roof trusses, Pi slabs, flat slabs as well as smaller bar-shaped elements and bridging joists. Paul casting bed equipment is available for various element sizes, up to heavy bridge girders.

During the planning phase we pay particular attention to designing your plant in such a way that it meets possible future requirements and complies with the highest demands of occupational safety. At the same time we always focus on the economic efficiency.

For prestressing precast concrete elements we supply

Casting bed equipment:

• Planning and in-depth advisory service
• Complete casting bed equipment for main reinforcement and (retrofittable) upper reinforcement (abutment anchor posts, transverse anchor plates, detensioning equipment, vertically adjustable supports, guards /safety devices, detensioning cylinders with support sleeves)
• Synchronous stroke display for detensioning equipment
• Anchor grips and couplers for wire and strand

Basic machinery equipment:

• Easy to operate stressing jacks, optionally with automatic elongation measurement and logging (TENSAcontrol system) with the appropriate hydraulic pump units with jack lifting unit, pneumatic tires and multiple connections or smaller and better manoeuvrable pump units for constricted space conditions
• Wire pushing machines and systems, also with steel cutters, either hydraulic or mechanical, as well as strand uncoiling reels and wire cages
• Detensioning pump units for soft force transmission for highest quality of the elements
• Force measuring units for calibrating the stressing jack and for stressing force control at the casting bed
• Cleaning lines for anchor grips
• Accessories and spare parts available in the long term

We should be glad to provide advice on the following subjects

• New construction, renewal or load increase for casting beds, change of the elements to be produced
• Multi-strand prestressing vs. single-wire/strand prestressing
• Quality optimization
• Efficiency optimization
• Cost-effective solutions
• and many more

Hollow core slabs or flat elements are endlessly produced on long casting beds using slide formers or extruders. After setting of the concrete the elements are sawn to the requested length.

For stressing on the sliding mould we supply

Casting bed equipment:

• • Equipment for casting beds of 1.2 m, 1.5 m and 2.4 m in width with a stressing force of 2000 kN to 4000 kN incl. abutment anchor plates (also arranged below floor level allowing the slide former to pass over)
• • With or without detensioning equipment (abutment anchor posts, detensioning anchors, detensioning cylinders)
• • If requested, also special solutions for your individual requirements
• • Anchor grips for wire and strand

Basic machinery equipment:

• Mobile and stationary synchronized multi-stressing systems
• Single-wire stressing jacks with force and elongation measurement and logging (TENSAcontrol system)
• Hydraulic pump units with jack lifting unit, pneumatic tires and multiple connections
• Strand uncoiling reels and wire cages, automatic wire pushing plants, strand cutters and wire cutters
• Detensioning pump units for soft force transmission for highest quality of the elements
• Force measuring units for calibrating the stressing jack and for stressing force control at the casting bed
• Cleaning lines for anchor grips
• Accessories and spare parts available in the long term
• Button heading machines and plants

We should be glad to provide advice on the following subjects

• Multi-strand prestressing vs. single-wire/strand prestressing
• Hydraulic detensioning
• Efficient set-up
• Alternative production of hollow core slabs or flat slabs on tables or using the carousel system

Prestressed concrete poles for advertising beams visible from a long distance, power lines, signal posts or other applications are produced at the precast concrete factory in a cost-efficient and effective manner and with consistent quality using various methods. Either pre-cut prestressing wires (also with button heads) or strands with anchor grips are used for this purpose. Depending on the method, all wires are prestressed in a bundle (particularly in the case of many small wires) or using a single-wire stressing jack. A rigid spun mould is often transmitting the stressing force.

Ram piles, however, are either produced on long casting beds or, in individual cases, using the carousel system.

For the production of prestressed poles or ram piles we supply

Casting bed equipment:

• Casting bed equipment with abutment anchor posts, transverse anchor plates, detensioning equipment, vertically adjustable supports and guards
• Detensioning cylinders with support sleeves
• Synchronous stroke display for safe detensioning

Basic machinery equipment for casting beds or rigid moulds:

• Strand uncoiling reels and wire cages, wire pushing machines and plants, optionally with hydraulic and mechanical steel cutters
• Button heading machines and plants
• Anchor grips and couplers for wire and strand, supports for flame-cutting the strand after setting of the concrete
• Stressing jacks, optionally with elongation measurement and logging (TENSAcontrol system)
• Pump units with jack lifting unit, pneumatic tires and multiple connections as well as detensioning pump units
• Force measuring units for calibrating the stressing jack and for stressing force control
• Cleaning lines for anchor grips
• Screw jacks and detensioning wrenches for threaded anchors
• Stressing force measuring units for threaded anchors
• Saws for prestressed concrete
• Accessories and spare parts
• Spiral coiling machines for rigid ring-shaped reinforcement

• Rigid mould vs. long casting bed
• Detensioning equipment
• Multi-strand prestressing vs. single-wire/strand prestressing
