Lay­her All­round Scaf­fold-Ideal for High-rise Struc­tures


More Pos­si­bil­i­ties with Lay­her Prod­ucts and Ser­vices

Ger­man com­pany, Lay­her, pro­duces high-qual­ity scaf­fold­ing sys­tems and has a world­wide pres­ence with more than 40 sales sub­sidiaries. Prod­ucts are be­ing used in the construction in­dus­try, in ce­ment, chem­i­cal, and power plants, and at ship­yards and in off­shore ap­pli­ca­tions.

Lay­her's ad­vanced prod­uct fea­tures and ap­pli­ca­tions, along with af­ter-sales ser­vices, help cus­tomers in­crease the prof­itabil­ity of their com­pa­nies. Lay­her’s All­round mod­u­lar scaf­fold­ing sys­tem has the ver­sa­til­ity, strength, and reli­a­bil­ity for use in construction sites, chem­i­cal in­dus­tries, power plants, air­crafts, ship­yards, in the­atres, are­nas and sta­di­ums.

Not only has the shape of the build­ing come to re­sem­ble a crys­tal, but also its pol­ished façade sur­face. To at­tach a lo­cal scaf­fold, the tech­ni­cal task was per­formed by Lay­her’s Scaf­fold­ing and Tech­ni­cal team. It in­volved sec­tion by sec­tion adap­tion of the scaf­fold to the slope of the build­ing, with var­i­ous

Se­lec­tion of an­chor­ing con­fig­u­ra­tion

An­chor­ing is es­sen­tial for the sta­bil­ity of the scaf­fold­ing, which must be con­tin­u­ally in­stalled as the scaf­fold­ing as­sem­bly pro­gresses. It is im­por­tant to pro­vide an­chor­ing on suf­fi­ciently strong com­po­nents, and if nec­es­sary, test­ing the an­chor­ing sur­face by pull–out tests. A check can be dis­pensed with if suf­fi­cient load-bear­ing ca­pac­ity can be as­sessed on the ba­sis of pro­fes­sional ex­pe­ri­ence, and the ser­vice value of the an­chor­ing force does not ex­ceed 1.5 KN, or in case of re­in­forced con­crete.

To con­nect a Hor­i­zon­tal Ledger with two stan­dard cou­plers with very wide scaf­fold­ing struc­tures, it must be nec­es­sary to an­chor with the aid of a hor­i­zon­tal ledger. The se­lec­tion of an­chor­ing con­fig­u­ra­tion de­pends on the bay width, the load on the scaf­fold­ing, live load, wind load, and the struc­tural height of the scaf­fold­ing. As the load on the scaf­fold in­creases, the an­chor­ing con­fig­u­ra­tion must be­come denser in or­der to pass the force safely into the an­chor­ing sur­face. The denser the an­chor­ing con­fig­u­ra­tion, lower the force on the in­di­vid­ual wall ties.

Ce­ment si­los are ei­ther part of the pro­duc­tion process in in­te­grated ce­ment plants, or as key stor­age cen­ters in dis­tri­bu­tion ter­mi­nals. As stor­age si­los in the ce­ment in­dus­try, they are very im­por­tant as they al­low con­tin­u­ous pro­duc­tion, while ce­ment dis­patch can be dis­con­tin­u­ous.

The largest ce­ment stor­age si­los in the ce­ment in­dus­try are built with di­am­e­ters of (upto) 30 m, while typ­i­cal si­los for stor­age of 20000 t ce­ment are 4 to 30 m in di­am­e­ter and 20 to 84 m in height. So, such si­los re­quire ef­fi­cient and trou­ble-free emp­ty­ing. Ac­cord­ingly, the strong­est em­pha­sis is on the over­all plant reli­a­bil­ity and 100% avail­abil­ity.

To achieve high avail­abil­ity, flow prob­lems have to be com­pletely elim­i­nated. The the­ory of flow in si­los well in­di­cates that this can only be achieved with mass-flow. For ce­ment si­los, the cen­tral cone ver­sion has be­come a pre­dom­i­nant de­sign. On one hand, the cen­tral cone has a dis­place­ment func­tion for the ma­te­rial in the silo. On the other hand, sev­eral de­signs, es­pe­cially for multi-com­part­ments, be­come pos­si­ble. Mul­ti­com­part­ment si­los are used for pro­duc­ing spe­cial ce­ments from a num­ber of main and sec­ondary ce­ment com­po­nents.

brack­ets on the in­side, and then shifted in­wards by one scaf­fold width. The scaf­fold was an­chored with the help of Lay­her’s an­chor­ing equip­ment, and even the in­creased wind loads could be trans­ferred with­out putting un­nec­es­sary strain on the struc­ture.

The construction of scaf­fold­ing for main­te­nance of a silo is a chal­leng­ing task due to wind pres­sures. It re­quires se­lec­tion of sup­port sys­tems (scaf­fold­ing with per­ma­nent struc­ture) and to avoid ob­struc­tions, brack­ets or a cable tray around the silo are used. Lay­her All­round Scaf­fold­ing sys­tem pro­vides a unique, bolt­less con­nec­tion tech­nique. In­fact, the patented All­round joint has re­placed the con­ven­tional scaf­fold tech­nique, es­pe­cially in construction of scaf­fold for si­los of heights upto 72 me­ters.

Lay­her All­round Scaf­fold­ing can ac­com­mo­date all types of high loads and is the ideal sys­tem for all kinds of sup­port scaf­fold­ing. It is an ef­fi­cient so­lu­tion for all chal­lenges, re­gard­less of whether they in­volve false work at great height, or round in­ner scaf­fold­ing. It needs to be built as a mod­u­lar scaf­fold­ing sys­tem for main­te­nance of si­los and high-rise in­dus­trial struc­tures. Ce­ment plant sit­u­ated near sea shores need to take care of the wind force. Mithilesh Ku­mar, Di­rec­tor, Lay­her Scaf­fold­ing Sys­tems
