Modern architecture

The current trend in modern

architecture is, by the skilful

use of steel and glass, to

present large-scale buildings

as airy, futuristic constructions

soaring skywards.

Outstanding features of this

style of building are roofs that

seemingly float on air, with

a filigree supporting frame-

work and skilfully suspended

facades.

The availability of special,

easily integrated fastening and

support elements is a pre-

requisite for the optimum

implementation of this form

of construction. The special

tension rod and compression

strut systems, as integral ele-

ments in the building design,

must guarantee maximum

functionality and safety. At

the same time they must

blend into the whole con-

struction as clearly visible

design elements with aesthe-

tic appeal.

mm··ccoonnnneecctt product program

The product range of m·con-nect tension rod and com-

pression strut systems was

specially developed for the

smooth fulfilment of these

tasks.

The products meet the tough-

est demands and, due to their

wide-ranging applicability, are

of great practical benefit to

• architects, • construction engineers • construction companies

Tension rod and compressionstrut systems

The m·connect tension rod

systems are the ideal compo-

nents to distribute tension for-

ces in an economical and,

at the same time, elegant

manner. They are suited to

all types of suspension and

anchoring. Connection plates

(circular disks) and connecting

lugs provide optimum additio-

nal features.

The m·connect compression

strut systems are able to bear

tension forces, but are also

specially designed to take up

and distribute compression

forces. They are ideally suited

to act as stabilizing elements

and supports, suspension

components on simultaneous

compression loads and com-

pression struts in frame con-

struction.

By combining compression

strut and tension rod systems,

additional construction poss-

ibilities are available.

Design elements of significance

As clearly visible elements,

the m·connect tension rod

and compression strut systems

are of crucial significance

in the representative design

of the building. They blend

easily, in a filigree fashion,

into the sophisticated archi-

tecture and shape the style

of the structure.

Elegant designs of lightweight construction

The highest demands were

made in the design and finish

of the components. This also

applies to structural connections,

such as the connection lugs,

whereby functionality is to be

expressed through the corre-

sponding design.

In line with the principle

design follows function the

distribution of material corre-

sponds to FE (finite element)

calculated operational stresses,

whereby for the fork heads,

the component function finds

convincing expression in the

optimized droplet shape. The

cap nuts consistently follow

the form of the fork heads and

by a smooth transition seem

to merge with the connecting

tension rod.

Prop supports

The m·connect construction

elements are designed strictly

according to the application

demands. In this way they

offer an economical and at

the same time attractive

solution to a wide range of

tasks in the field of construction.

As the distribution of materi-

al corresponds to the loads

imposed, the high-tensile

materials are exploited to

the optimum level.

This permits lightweight cons-

truction at maximum loading

capacity.

The modular system and

corresponding enginering soft-

ware further facilitate imple-

mentation and speed up the

design and construction cycle.


07

The application possibilities

of the m·connect tension

rod and compression strut

systems are as diverse as the

possibilities in construction,

whether in steel, steel/wood

or steel/glass.

• exhibition halls

• bus terminals

• bridge building

• pedestrian bridges

• galleries

• airport buildings

• glass roofs

• glass facades

• industrial workshops

• shopping malls

• congress halls

• sports centres

• tower constructions

• covered sheds

• roofing

• canopies

• tent constructions

Multiple applications

With the m·connect tensionrod and compression strutsystems, typical static designchallenges can be expertly,elegantly, stylishly and eco-nomically solved - at a singlestroke!


FORK HEADS

Only a few components are

required for the formation

of m·connect tension rod and

compression strut systems.

The fork heads are of crucial

importance in the system as

connections for the structural

attachments (see p. 14).

The operational load capacity

of the fork heads is approved,

both for tensile and compres-

sion loads. They are corres-

pondingly designated for use

in tension rod and compres-

sion strut systems.

A quenched and tempered

steel casting, manufactured in

a quality lost-wax investment

process, bestows the compo-

nent with great strength and

excellent cold tenecity.

For maximum corrosion pro-

tection of the threaded con-

nection, the tapped hole

takes the form of a pocket

not a drilled-through hole.

TENSION RODS

The MÜRMANN plant can look

back on more than 40 successful

years of experience in the

manufacture of threaded rods

and studs. The threads can be

produced by cutting (CNC or

cutter head), rolling or spinn-

ing process. The tension rods

are equipped with left-hand /

right-hand threads for length

adjustment and with flat faces

on both sides. Individual rod

lengths of up to 12 m can be

supplied as standard. The

high-strength fine-grained

structural steel S460N is the

standard component material.

Other materials, including a

range of stainless steel can

also be supplied.

CAP NUTS

The m·connect cap nuts are

used to lightly lock the tension

rod and also serve to cover

the exposed thread.

To maintain the minimum

engagement depth, no threa-

ding must be visible after a

cap nut is screwed on!

CONNECTING SLEEVES

The m·connect sleeves are

used as connecting parts

between the tension rods if

the system length, e.g. above

12 m, is to be extended.

Through standardised design

with left-hand/right-hand threads,

they function as a turnbuckle

at the same time.

CONNECTING SLEEVES WITH LUGS

The connecting sleeves can be

fitted with suspension lugs

for load-bearing in horizontally

arranged tension rod systems

(underbracing).

� The compression resistance N given is calculated according to DIN EN 1993. The static resistance must be verified for each critical load

case. To verify static resistance the acting loads are multiplied by the partial safety factors or combination factors. Static resistance is given if

the values calculated in this manner do not exceed the compression resistance of the compression bar selected.

CONNECTION PLATES

The m·connect connecting

plates are required in frame

constructions as central junct-

ion points. In standard designs

three or four tension rods can

be attached.

To guarantee a secure load

distribution, only m·connectconnecting plates with the

material quality and dimensions

corresponding to calculations

should be implemented.

The direction of forces always

passes through the junction

point – an angle displacement

of 5 % is permissible.

For selection according to a

particular design the basic

shapes, e.g. rectangular or

circular, are offered as stan-

dard. Variants can however

be supplied.

STRUCTURAL ATTACHMENTS

As structural attachments,

connection lugs are required

with geometries and properties

which meet both building

requirements and the size

and nature of the loads given.

For safe load-bearing by the

tension rod or compression

strut systems, strict observ-

ance of the specifications

regarding material quality and

dimensions must be guarant-

eed. The exclusive use of

m·connect connection lugs is

recommended.

The specifications for welding

seams (p. 26) must also be

strictly followed.

As standard solutions, the

basic shapes for the most

important installation situa-

tions are suggested in our

catalog for selection accord-

ing to a particular design.

Variants can also be supp-

lied.

Further practical componentsfor steel constructionApart from the connection

lugs, other practical connection

elements can be offered from

the MÜRMANN and LISEGAproduct ranges.

Beam adapters Type L 76

With these beam adapters,

clamping joints are created

which, with the correspon-

ding pre-stressing, ensure

form-fitting at the contact sur-

faces and thereby high

security against displace-

ment due to lateral forces.


� �

Beam clamps Type L 78

Beam clamps are flexible due

to their form of construction

and can be supplied in many

versions for all kinds of sup-

ports for practically any type

or size of beam.

Threaded clevises Type L 61

Threaded clevises are, in

combination with threaded

rods, an economical alterna-

tive to costly welded lug

designs for support bracing

and fixing.


Functionality and Safety

20

Finite element calculation and supplementary load tests

ensure the maximum degree of safety.

The system components fulfil

crucial load-bearing funct-

ions in the statics. The

demands on these compo-

nents regarding safety and

reliability are correspondingly

high.

DESIGN

In their design, ample safety

factors were considered. The

specifications are in full accor-

dance with current regulations

and have undergone expert

scrutiny by the Institute for

Structural Steel Engineering

at the University of Brunswick

and have been certified by

the German Institute of

Structural Engineering in

Berlin under the number

Z-14.4-441 of 12.01.2004

and comply with DIN 18800.

QUALITY ASSURANCE

The technical supervision and

manufacture of the system

components is carried out

at the MÜRMANN Gewinde-

technik (Thread Technology)

plant in line with the requi-

rements of certified quality

assurance according to DIN

EN ISO 9001. Suppliers are

also subject to the corre-

sponding certification and

approval.


21

Rational application via modular systemAt the conception of the

m·connect product program,

rational application stood at

the forefront together with

functionality and design:

simple engineering, simple

application and simple install-

ation.

A prerequisite was to con-

ceive the product range as a

modular system.

Standardised according to

uniform criteria, the individual

components are assembled

herein as modules. Through

strict classification as to

loads and connection geo-

metries, the components wit-

hin a load group are comp-

atible with regard to connect-

ions. They can consequently

be assembled at will to form

functional load chains. At the

same time the combination of

components of different load-

bearing capacity is excluded.

For projects, engineering can

be executed very easily and

safely using this catalog or,

even more conveniently, by

electronic means with our

CONNCAD® software program

(see p. 23).

As integrated elements in

suspension and support con-

structions, the m·connect-load chains fulfil important

tasks in building structures.

The range of applications is

considerable and the multiple

combination possibilities of

individual components are

designed to fulfil almost all

practical demands.

Verification of static resistance

For each critical load case,

the verification of static

resistance shall be determined:

Examples for typical load

cases:

- permanent loads

- permanent loads plus one

leading variable load

- permanent loads plus one

leading variable load and

other variable loads

For the verification of static

resistance, the acting loads

has to be multiplied with the

relevant partial factor resp.

factor of combination (s. DIN

EN 1990, Annex A1 resp.

national annexes).

The static resistance is given,

when the above calculated

values do not exceed the

tension resistance NRd of the

selected thread size.

For surface protection against

corrosion, selection can be

made from the usual types

of corrosion protection:

Only materials meeting DIN,

guaranteed strength values

are selected.

CONNCAD® - DESIGN ANDENGINEERING PROGRAM

For the swift and simple

design and planning of

m·connect tension rod and

compression strut systems,

the user has our design

and engineering software

CONNCAD® at his disposal.

The basis of this special user-

friendly program is the

m·connect modular system

(p. 21) and the coding of

components (p. 24).

CONNCAD® helps to save

time and cut costs. Just a

few mouse clicks suffice to

generate ready-to-order

design documentation, to

scale and in the required

detail.

By way of the appropriate

interfaces the designs can be

fed into common CAD pro-

grams. The usual time and

effort spent on planning is

thereby reduced to a mini-

mum. CONNCAD® is availa-

ble on our homepage under

www.mconnect.eu or for

downloading free of charge.

are of crucial significance as

load-bearing components for

the load-bearing capacity of

the whole construction.

Observation of the following

instructions is a prerequisite

for trouble-free functioning.

If the components in the tensi-

on rod system are subse-

quently subjected to thermal

or mechanical treatment, the

building supervision certifica-

tion loses its validity.

1. Delivery condition

1.1. The m·connect tension rod

and compression strut

systems are preassembled

and supplied as ready-to-

install load chains with the

corresponding markings.

1.2. If connection lugs are

also supplied, they are

separately marked with the

installation position and tied

to the tension rod system

with binding wire.

1.3. To guarantee the given

load capacity of the connect-

ion lugs, the welding speci-

fications under Point 3 of these

instructions must be strictly

adhered to.

2. Packaging

2.1. Wooden laths are used

to protect the tension rod

systems from damage. The

delivery packages are wrap-

ped in foil as protection

against dust and dirt.

Wooden crates are used for

the delivery of individual

components.

2.2. On delivery the compo-

nents must be inspected for

transport damage and protec-

ted against moisture by storage

in closed rooms until assembly.

3. Welding procedure forconnection lugs

The following procedure is

recommended when welding

connection lugs:

3.1. The minimum welding

seam thickness (a) for

connection of the lug to a

supporting structure depends

on the shape of the

connection lug and the angle

of load distribution.

3.2. The “a” dimensions

according to lug type are

given in the table.

3.3. Connection lugs for ten-

sion rod systems M56x4

(corresponding to see thickn-

ess 35mm) must be

preheated to approx. 100°C.

3.4. Only approved welding

filler metals (Ü-stamp), prefe-

rably base electrodes (e.g.

EN499; E 42 5 B4 2 H5) are

permissible.

3.5. Vertical seams are only

to be welded using the

appropriate welding filler

metals (e.g. EN499: E38 0 RC

1 1).

3.6. Spot welds are to be

made with an intermediate

layer temperature � 250°C.

3.7. Delays in welding are to

be avoided by the appropria-

te welding sequence (see

Fig. 1)

3.8. The connection lugs are

always to be welded all aro-

und.

4. Installation

The following procedure is to be followed when installing the

preassembled load chains:

4.1. Before installation it is advisable to check that the install-

ation dimensions correspond with the lengths delivered.

4.2. Loosen cap nuts, screwing them back a little.

4.3. Remove the circlips on the pins at the forked ends

and extract the pins.

4.4. Position the fork heads on the connection lugs and make

the pin connections. Sudden loading of the fork heads is not

permissible.

4.5. If length adjustment is required, it is only to be made by

rotating the tension rod; in this way the engagement depths

of the left-hand/right-hand thread are kept equal and the

maximum adjustment possibility is maintained.

4.6. For the proper functioning of the tension rod, the end

connection must be free of play. Therefore sufficient prestress

must be applied by rotation of the rod. It is recommended to

turn both ends at the same time.

4.7. To ensure minimum engagement depths, the tension rod

thread must be fully covered by the tightened cap nuts. If no

cap nuts are ordered, the visible thread length must not

exceed the catalog dimension L (p. 10) of the cap nut.

4.8. Tighten the cap nuts. The screw connections are supplied

with permanently elastic, silicon-free sealing material. If the

tension rod systems are to be used in the open, the gap

between cap nut and tension rod should be filled with a

suitable sealant.
