layer is right angle to the grain in the adjacent layer.

The Chief advantages of plywood over a signal board of the same thickness is the more uniform strength of the plywood,

along the length and width of the plywood and grater resistance to cracking and splitting with change in moisture content.

Usually synthetic resins are used for gluing, pherolic resins are usually cured in a hot press which compresses and

simultaneously heats the plies between hot plates which maintain a temperature of 90 degrees C. to 140 degrees C. and a

pressure of 11 to 14 kg/sq.cm. on the wood. The time of heating may be anything from 2 to 69 minutes depending

When water glue are used , the wood absorbs so much water that the finished plywood must be dried carefully. When

synthetic resins are used as adhesive finished by plywood must be exposed to an atmosphere of controlled humidity until

the proper amount of moisture has been absorbed.

Accordingto I.S. 303-1975 the plywood for general purpose shall be of three grades BWR, WWR and CWR, depending

upon the adhesives used for bonding and veneers, and it will be further classified into six types namelyAA,AB,AC,BB,BC

plywood should be reconditioned to a moisturecontent not less than 8 percent and not more than 16 percent.

When architects and designers approach us with a tensile fabric structure idea, sometimes they know what type of fabric

they want, other times, they look to us for direction.This article provides an overview on the fabrics we design & build

with. Today’s fabrics are innovative, allowing you to create iconic spaces.

A coated structural fabric consists of a woven base cloth stabilised and protected by a coating on both sides. The base cloth

consists of warp threads running the length of the roll and weft threads running across the width.

A mesh fabric is a coated cloth with spacing between the thread bundles. With some meshes for interiors use the threads are

coated before weaving.

A typical structural fabric would have a tensile strength of 10 tonnes in the warp and weft direction. A factor of safetyof

on a maximum design loads is used select a cloth although this may be reduced if the circumstances are well understood ie.

if the maximum strength of the membrane is 10 tonnes/linear metre the maximumpermissible load would be

tonnes/metre, and the typical pre-stress load would be 150-350kg/metre.

not feasible, overlapping bars shall be bound with annealed wires not less than 1 mm

thick twisted tight. The overlaps shall be staggered for different bears and located at

points along the span where neither shear nor bending movement is maximum.

Whenever indicated on the drawings or desired by the Engineer-in-charge, bars

shall be joined by couplings which shall have a cross-section sufficient to transpit the full

stresses of bars. The ends of the bars that arejoined bycoupling shall be upset for

sufficient length so that the effective cross section at the base of threads is not less than

normal cross-section of the bar. Threads shall be standard threads. Steel for coupling shall

maximum diameter not exceeding the nominal diameter of rivets or bolts.

Drifting done during assembling shall not distort the metal or enlarge the holes.

The shanks of rivets shall project beyond the plate surface sufficiently so as to

fill the hole thoroughly and from the required head after riveting.

The riveting shall be done by hydraulic or pneumatic process. However where such facilities are not available,

hand riveting may be permitted. The rivet shall be heated red -hot, care being taken to control the temperature of

heating so as not to burn the steel. Riveting of diameter less than 10 mm may be fitted cold. Rivets shall be of

heat finish with heads full and of equal size. All loose, burnt or badly formed rivets with concentric or deficient

heads shall be cut out and replaced. The heads of rivets shall be central to shanks and shall grip the
