Design and Use of Inserts for Lifting and Handling of Precast Concrete - Elements

Design and Use of Inserts for Lifting and Handling of Precast Concrete - Elements

This Technical Report provides recommendations for the choice and use of cast-in steel lifting inserts, hereafter called 'inserts' for the handling of precast concrete elements. They are intended for use only during transient situations for lifting and handling, and not for the service life of the structure. The choice of insert is made according to the lifting capacity of their part embedded in the concrete, or may be limited by the capacity of the insert itself and the corresponding key declared by the insert manufacturer. The report covers commonly used applications (walls/beams/columns and solid slabs and pipes) and the range of these applications is further limited to prevent other types of failure than concrete breakout failure (cone failure), failure of supplementary reinforcement or failure in the steel insert. A basic supposition is that the concrete is demonstrably uncracked during all lifting situations.
The limitation in scope is used to obtain simple design models. Further information may be found in [1].
The recommended safety levels are intended for short-term-handling and transient situations.
This Technical Report applies only to precast concrete elements made of normal weight concrete and manufactured in a factory environment and under a factory production control (FPC) system (in accordance with EN 13369:2004, clause 6.3) covering the insert embedment.
This Technical Report does not cover :
-   The design of the insert itself (for inserts manufactured by insert suppliers).
-   The lifting key that hooks on to the embedded lifting insert as a component between the insert and the lifting machinery (crane, excavator...), nor its compliance with the embedded insert. These components, when brought to the market separately, are covered by the Machinery Directive (98/37/EC).
-   Lifting inserts for permanent and repeated use.
This report is not an interpretation of the Machinery Directive.

Conception et utilisation d'inserts pour le levage et la manutention des éléments préfabriqués en béton

1.1   Domaine d’application / Généralités
Le présent Rapport Technique fournit des recommandations pour le choix et l'utilisation d'inserts de levage en acier noyés, ci-après appelés « inserts » pour la manutention d'éléments préfabriqués en béton. Leur utilisation n'est prévue que pendant des situations transitoires pour le levage et la manutention et pas pendant la durée de vie en service de la structure. Les inserts sont choisis en fonction de la capacité de levage de leur partie incorporée dans le béton, ou ce choix peut être limité par la capacité de l'insert proprement dit et de la main de levage correspondante fournie par le fabricant d'insert. Le rapport couvre des applications utilisées couramment (murs/poutres/poteaux et dalles pleines et canalisations), la plage de ces applications étant en outre limitée pour empêcher des  types de rupture autres que la rupture par arrachement du béton (rupture du cône), la rupture de l'armature supplémentaire ou la rupture de l'insert en acier. Une hypothèse fondamentale est que la preuve est apportée de l'absence de toute fissuration du béton pendant toutes les situations de levage.
La limitation du domaine d'application sert à obtenir des modèles de conception simples. La référence bibliographique [1] donne de plus amples informations.
Les niveaux de sécurité recommandés concernent la manutention de courte durée et les situations transitoires.
Le présent Rapport Technique s'applique seulement aux éléments préfabriqués en béton façonnés à partir de béton de poids normal et fabriqués dans un environnement d'usine et sous un système de contrôle de production en usine (CPU), conforme au paragraphe 6.3 de l'EN 13369:2004, couvrant l'enrobage de l'insert.

Sustainability of construction works - Environmental product declarations - Product Category Rules for concrete and concrete elements
SIST EN 16757:2023

This document complements the core rules for the product category of construction products as defined in EN 15804:2012+A2:2019 and is intended to be used as a c-PCR in conjunction with that standard.
This c-PCR applies to products within the scope of CEN/TC 104 and CEN/TC 229, but it may be applicable to other concrete products until they have product specific c-PCRs.
This document applies to concrete and concrete elements for building and civil engineering, but excludes autoclaved aerated concrete and resin bound concrete. Apart from Annex G, it may be used as guidance for glass fibre reinforced concrete.
This document defines the parameters to be reported, what EPD types (and life cycle stages) to be covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.
In addition to the common parts of EN 15804:2012+A2:2019, this document for concrete and concrete elements:
-   defines the system boundaries;
-   defines the modelling and assessment of material-specific characteristics;
-   defines allocation procedures for multi-output processes along the production chain;
-   defines allocation procedures for reuse and recycling;
-   includes the rules for calculating the LCI and the LCIA underlying the EPD;
-   provides guidance/specific rules for the determination of the reference service life (RSL);
-   gives guidance on the establishment of default scenarios;
-   gives guidance on default functional units for concrete elements.
This document is intended to be used either for cradle to gate with options or cradle to grave assessment, provided the intentions are properly stated in the system boundary description.
Within the construction works context, a cradle to grave declaration delivers a more comprehensive understanding of the environmental impact associated with concrete and concrete elements.

Design and use of inserts for lifting and handling of precast concrete elements
SIST-TP CEN/TR 15728:2016

1.1   General
This Technical Report provides recommendations for the choice and use of cast-in steel lifting inserts, hereafter called 'inserts' for the handling of precast concrete elements. They are intended for use only during transient situations for lifting and handling, and not for the service life of the structure. The choice of insert is made according to the lifting capacity of their part embedded in the concrete, or may be limited by the capacity of the insert itself and the corresponding key declared by the insert manufacturer.
The report covers commonly used applications (walls/beams/columns and solid slabs and pipes). The range of these applications is further limited to prevent other types of failure than concrete breakout failure (cone failure), bond failure, failure of reinforcement or failure in the steel insert.
Due to lack of information this report does not cover double shell walls, floor plates and beams for beam-and-block floor systems.
The safety levels are given for information and are intended for short-term-handling and transient situations.
This Technical Report applies only to precast concrete elements made of normal weight concrete and manufactured in a factory environment and under a factory production control (FPC) system (in accordance with EN 13369:2013, 6.3) covering the insert embedment.
This Technical Report does not cover:
-   the design of the lifting inserts independently placed on the market;
-   lifting inserts for permanent and repeated use.
This Technical Report is prepared based on the fact that the anchorage in the concrete of parts of the lifting assembly is governed by the Construction Products Regulation. Lifting accessories independently placed on the market are governed by the Machinery Directive.
1.2   Types of inserts for lifting and handling
This Technical Report applies to the embedment of lifting inserts. Devices made by the precaster may consist of smooth bars, prestressing strands, steel plates with anchorage or steel wire ropes. The system devices may be e.g. internal threaded inserts, flat steel inserts and headed inserts.
Lifting loops of ribbed bars are not covered.
1.3   Minimum dimensions
This Technical Report applies in general to inserts with a minimum nominal diameter of 6 mm or the corresponding cross section. In general, the minimum anchorage depth should be hef = 40 mm.
Wire ropes of diameter less than 6 mm are not covered.

Precast concrete products - Bridge elements
SIST EN 15050:2007+A1:2012

This European Standard applies to precast concrete structural elements produced in a factory and used in bridge construction, such as deck elements.Normal weight concrete elements are considered, both reinforced and prestressed; their use can be on road bridges, railway bridges and footbridges.
Deck elements include both single elements from which the deck may be composed (beams, slabs, ribbed or cellular elements) and elements consisting of a segment of the entire deck.
Some examples of elements dealt with are shown in Annex A.
The durability aspects are also considered.
This European Standard makes reference to precast elements produced in a factory or near the construction site in a place protected from adverse weather conditions. It is assumed that if the elements are not manufactured in a factory, the production conditions assure the same level of quality control as in a factory. It is assumed that the production place is protected from rain, sunshine and wind.
Some of the elements are also treated in other European Standards (e.g. beams, slabs). This European Standard deals with the specific aspects related to the use of these elements in bridge construction.
Foundation piles, piers, abutments, barriers, bumpers, guards, arches and" box culverts are out the scope of this European Standard.

Precast concrete products - Box culverts
SIST EN 14844:2006+A2:2012

This European Standard deals with both large (structural) and small (non-structural or light structural) box culverts of rectangular cross-section formed monolithically and designed as continuous elements with a joint detail shaped to allow the possible incorporation of sealing materials. Box culverts can be used for creation of voids below ground for conveyance and storage of materials. e.g. conveyance and storage of wastewater, cable tunnels and subways
For the purposes of this European Standard, box culverts having internal cross-sectional dimensions (W and H in Figure 1) less than or equal to 1 250 mm are considered as small (non-structural or light structural). All other units are defined as large. The elements are generally manufactured in factories using either normal weight or lightweight concrete and usually require reinforcing steel. This standard does not include units manufactured from autoclaved aerated concrete, nor prefabricated reinforced box culverts of lightweight concrete with open structure.
Each unit is structurally complete. They are used in combination to form a total structure of appropriate length (including joints) and capacity.
