Standard

Stremaformworking joints enable large

structural elements to be formed in sections.

The sequence of these work ing joints is

precisely scheduled depending on work at the

construction site. Working joints may be fitted

with water stops and / or with transverse force

dowels for absorption of shear forces.

with water stopStandard

Expansion joints or movement joints separate

structural elements made of concrete from

each other. EPS or mineral wool inserts are

used to form the required joint between the

structural elements. Watertight expansion joints

are produced by incorporating a waterstop.

Stremaform

elements are prefabricatedin our factory, ready for installation on site.

Stremaformelements can be manufactured

with a metal waterstop or a rubber water bar

cage. The rubber water bar is installed in the

cage at the construction site.

with water stopStandard

Controlled crack joints

Stremaformcontrolled crack joints are used

to produce intended cracks in working joints

by deliberate weakening of the concrete cross

section. The cross section is weakened by

introducing a separation layer, which prevents

the production of a concrete bond within one

third of the concrete cross section.

Other types of expansion joints

Stremaformformwork elements for expansion

joints can be fitted in our factory with dowels

(Egcodubel) or with transverse force dowels

(Egcodorn) for absorption of shear forces.

For mass-spring-systems we use dowels whichhave also been approved for transmission of

dynamic loads.

Benefits of Stremaform

1. pour 2. pour

The resistance of construction joints

produced with Stremaformto shear forces

is identical to the values obtained with

monolithic concrete.

StremaformSpacer ensures a reliable

concrete cover and formwork for the lower

reinforcement layers without any gaps.

Water stops are integrated in our factory. Reduced assembly time, formwork

elements will be shaped to size in our factory.

No formwork removal required.

Anchors placed at the rear side of the

formwork elements provide for increased

freedom of movement in the second concrete

pour.

Short delivery times due to sufficient stock

accompanied by quick cutting to size in our

factory.

No need for formwork removal, i.e. the

reinforcement can be continued withoutinterruption in the second concrete pour.

Our transport department with factory owned

trucks guarantees fast dispatch and reducesdelivery times to the construction site to a

minimum.

Quick manufactureto your layout drawings

On receipt of your layout drawings our design

department will submit proposals for suitable

jo int designs.

Stremaform elements will be shaped to

the required size in our factory so that they

are ready for quick on-site installation in

conformity with installation layouts supplied.

Stremaform

Stremaformis the formwork material for medium size slabs and walls. Stremaformis

fixed between the reinforcement layers.

With its rough sur face Stremaform

flat material satis

fies the requirements of an indented

joint to DIN 1045-1.

A metal water stop or a rubber water bar cage can be instal led in our factor y if required.

The formwork is supplied precisely to your layout specifications.

StremaformStrong

StremaformStrong with factory made stiffening made of lattice girders is suited for any

dimensions of structural elements.

If required, a metal water stop or a rubber water bar cage can also be installed in this case

as well.

Stremaform

Strong is supplied precisely to your layout specifications.

Stremaweb

Stremaweballows for the uninterrupted installation of reinfoorcement. Stremaweb

consists of a specially designed expanded mesh with a fibre concrete rail bar top and

bottom. The rail ensures correct cover and the reinforcement is easily pushed through

the mesh. Stremawebelements are produced precisely according to your layout

requirements.

Stremaboard

Stremaboard consists of a profiled, lightweight expanded metal:

The profile satisfies requirements to DIN 1045-1, so that working joints produced with

Stremaboard are classified indented joints.

Stremaboard is supplied on pallets in quantities of 100 pcs./pallet, with the following

dimensions, which will be cut to size at site:

Stremaform Standard

The bond between concrete and Stremaformprovides a

shear strength equivalent to that of monolithic concrete

Manufactured to size in our factory, Stremaformeliminates

the need for traditional formwork erection and stripping, as

well as subsequent scabbling of the joint resulting in faster

pouring cycles

Maximizing of f-site prefabrication minimizes work on the

construction site and guarantees fast progress of the

project.

Stremaform

Stremaformis used as lost formwork for working joints in floor

slabs, ceilings and walls. Consisting of an expanded metal

welded between steel bars, Stremaform is placed between

the reinforcement bars providing a rough surface to the finished

concrete.

This sur face forms an indented structure with the second

concrete pour so that the working joint transfers shear forces

identical to those obtained with monolithic concrete (proven by

tests carried out at the IBMB Brunswick).

StremaformStrong StremaformStrong

with indented joint

Formwork elements for very large working joints can be

No additional formwork elements are required for the 2nd

concrete pour due to rear anchoring via supports in the first

concrete pour.

Installed Stremaformformwork elements remain in the

concrete and reinforcement layout is unaffected.

StremaformStrong

StremaformStrong is the combination between Stremaform

flat material with factory-made stif fening and it is eminently

suited for use with thick structural elements.

Factory made stiffening of the rear side with girders (e.g. with

Stremafix) produces formwork elements for any size of working

joints.

Stremaform Foundation Box-outs

Using a Pecafil external formwork in combination with

Stremaforminternal formwork, individual column foundations

can be easily and economically produced.

Pecafilformwork elements can be reused for several identical

foundations. They can be easily moved to a new position

manually without the need for lifting equipment.

Foundation Box-outs

Stremaformformwork elements are used to form box-outs in

foundations that are used as a recess for subsequent production

of supports and columns.

After completion of the foundation slab or individual foundations,

steel or reinforced concrete columns can be positioned exactly

according to the layout.

The internal sur face of the box-out produced by Stremaform

formwork elements is perfectly indented. Between the column

and base slab there is a positive connection after pouring of the

infill concrete.

Stremaform Box-Outs / Hoppe r formwork e lements

Hopper formwork elements

Hopper formwork elements are used to produce conical

concrete structures (e.g. for wastewater treatment plants or

silos) where they form the upper formwork. The surface is

subsequently covered with a screed to the required concrete

cover. Fixing at the bottom via anchors / lift protectors prevents

the risk of flotation.

Stremaformhopper formwork elements can also be supplied

complete with factory-made bracing.

Box-Outs

Stremaformformwork elements for box-outs are used for wall

or slab openings. These openings for e.g. large diameter pipe

leadthroughs, are subsequently filled with concrete.

Stremaform formwork elements for recesses are available in

various designs and sizes.

Many options are available, such as elements with stiffening,

concrete cover rails, chutes, with seals and wooden covers

used as drop protection.

Due to the special design of the expanded mesh, reinforcement

bars can simply be pushed through the formwork element.

Fibre concrete rails and integrated accurately positioned rebars

integrated dynamic transverse force

dowels for expansion joints

Mass-spring systems are used to prevent the transfer of vibrations

and for railways this means resting concrete bases on a resilient

material. This creates strains and at expansion joints it is necessary

to transfer dynamic forces across the joint. These dynamic forces

can be transferred via the use of special dynamic transverse force

dowels (Egcodorn type DND). To speed up work cycles at the

construction site we manufacture and deliver prefabricated units

consisting of the Egcodorn dowels integrated into Stremaform

formwork element for expansion joints. These units are simplydropped into position and tied into the main reinforcement. This

type of construction ensures fast and accurate placement of the

dowels and expansion joint material and ensures uninterrupted

work progress, thus speeding up completion of concrete

structures, i.e. a major benefit especially for tunnel construction.
