DELTABEAM® Frame Composite Frame System – On site

The DELTABEAM® Frame components are delivered to the site according to the agreed project schedule. What should be taken into account in terms of storing, lifting, moving, and installing the components?

Storing DELTABEAM® Frame Components

Components are marked with identification codes in accordance with the drawings. Beams, columns and other steel members can be stored in piles but remember to verify the bearing capacity and the level of the surface. Piling strips (wooden logs) must be used under the steel members to protect the surface treatment. Piling strips should be free from grease or other substances that may damage the surface treatment. For long‑term storage, steel structures must be covered.

Lifting and Moving DELTABEAM® Frame Components

DELTABEAM® Frame components can be lifted and moved using ordinary lifting equipment, such as cranes or forklifts. The weight of each structural element is displayed on the product sticker or in the fabrication drawings. Within the EU, all structures have the CE marking sticker.

DELTABEAM® must be lifted using the lifting holes on the top plate. The holes are placed symmetrically to the axis of the center of mass. The maximum allowed lifting angle of the chains must be notified.

In special cases, when there are no lifting holes, DELTABEAM® can be lifted with chains attached to the web holes. Sometimes a third chain is needed in order to maintain balance. For example, DELTABEAM® with wide inbuilt formwork should be lifted using the lifting holes and a third chain should be assembled to the formwork.

Columns are lifted using hoist bracket located at the top of the column.

Installing DELTABEAM® Frame Components

DELTABEAM® Frame components are installed according to the project’s erection method statement, installation plan, propping plan, and connection details.

The project’s erection method statement must be followed at all times. Every DELTABEAM® Frame component has an identification code. The beams are installed in such a way that the identification code on the top plate of DELTABEAM® can be read in the direction marked in the element layout drawing. Casting port location is used as orientation mark for composite columns. Casting port location is shown in the drawing.

The DELTABEAM® Frame components weight is not effective enough to stabilize the frame during installation of the slabs. Therefore, DELTABEAM®s should be connected prior to assembling the floor units in order to prevent the beams from moving. Minimal or no propping is required when the connection details and supporting structure are designed to transfer loads from the DELTABEAM® to the supporting structure. Always follow the propping plan and the installation instructions before placing the slabs.

Slab Installation

The DELTABEAM®’s connections and props must be securely installed, tightened, or welded before assembling the floor units. To minimize the rotation of the beam, the floor units should be assembled alternately on different sides of the beam. After the slabs are installed, the necessary formwork, edge forming, and slab reinforcement will be carried out.

Floor units should be assembled directly on the beam ledge. The transverse reinforcement should always pass through DELTABEAM®’s web holes or the additional web holes.

Casting of DELTABEAM®

DELTABEAM®s are cast with structural concrete simultaneously with the slab or the joints of hollow‑core slabs. DELTABEAM® must be cast completely in one run in order to secure the properties of a composite beam.

Casting of the Composite Columns

Columns are filled with concrete by pumping the concrete in from the foot of the column. Concrete filling from bottom ensures good compaction and can be executed so that it doesn’t interrupt assembly of other components and it’s not prolonging construction time of the frame. Column should be filled in one run.
