SOLUTIONS FOR HIGH RISE APPLICATIONS

Richa Steel structure is an ideal solution for High Rise applications as today in urban Infrastructure there is a space crunch and such buildings are an appropriate solution to this problem and are cost effective too due to optimized use of steel.

Steel Buildings can be built as per architectural design for optimized energy requirement, such as Natural cooling, solar gains & natural day light

These buildings incorporate a high level of services which can be easily interfaced within our system: Air conditioning system ducts, flooring, electric power plants for essential facilities , fire protection system and all other Mechanical and electrical services easily designed in our Structural system


BENEFITS OF USINGSTEEL STRUCTURES

Beter ROI due to speedy construction of superstructure Lighter in weight due to use of High strength steel, hence lighter foundations required Internal dry wall partition system and acoustic proofing helps to keep structure lighter

along with quick erection time Provision for all MEP and other services offsite planning Large span are possible in reception, lobby, function halls, food court etc Architectural aesthetics and energy efficient views Modern amenities provision and efficient work space Customized solution to each and every need

PROCESS OF MANUFACTURINGSTEEL STRUCTURES


FABRICATION

Structural steel members are fabricated by precisely cutting, sharing, punching, drilling, fitting and welding in order to produce the configurations detailed in the shop drawings. Each member is labeled with a piece mark, length, and job number for identification.

LABELLING

Once fabricated, each finished structural steel member is labeled. In this case the fabricator labels each steel member with its piece mark, sequence number, and the last two digits of the job number. Richa uses specific labeling practices. In the image, the label color is yellow to differentiate it from previous labels. Labeling of the steel pieces is crucial because it helps identify members on the job site.


STORAGE

After fabrication, finished structural steel members are stored in the storage yard. The yard is properly organized and it makes easier to transport steel to the site in phased manner. Steel structures are stored according to erection sequence. Sequences define areas of the frame and are used to organize their delivery and erection. The practice of planning and storing by sequence improves the efficiency of loading, delivery, offloading and erection.


ANCHOR BOLT PLAN

One of the first drawings prepared by the detailer is the Anchor Bolt Plan. This plan guides the foundation subcontractor in the placement of anchor bolts. It contains horizontal and vertical information for placement of anchor rods, as well as dimensions and elevations of leveling plates (if used).d).


ANCHOR BOLT SURVEY

Before the erection process started, anchor bolts and leveling plates are surveyed to check if they are correctly positioned. If anchor rods are improperly located, they are corrected by the foundation subcontractor before the erection process may start. The surveyor uses a total station to determine the horizontal and vertical location of each leveling plate and anchor bolts.

ERECTION PROCESS

An animation of the steel structure erection process sequence wise


ERECTION TEAMThe Erection Team consists of One Project Manager, One Foreman, 3-4 Iron workers for hooking steel, three to four iron workers connecting steel and a crane operator.


CRANES

Cranes are selected on the basis of cost, availability, speed, reach and capacity. There are many configurations and sizes of cranes available.

UNLOADING & SHAKEOUT

Upon delivery to the job site, fabricated steel unloads and places on wood or steel blocking. The blocking allows for chokers to be attached to each member for subsequent hoisting and erection. Shakeout of structural steel takes place after unloading. Shakeout is the process of sorting the steel pieces on the site so that they can be efficiently erected, and involves organizing and spacing each structural steel piece.


ERECTION DRAWING

This is the erection drawing of floor framing for a project. The numbers one and two inside the red hexagons on each side of the red line indicates the sequence number for each part of the structure. The piece marks on the drawing matches those on the beams, girders and columns and are used to locate and orient each member during erection.

2. INSTALL BEAMS AND GIRDERS

3. PLUMB STRUCTURES

4. COMPLETE ALL CONNECTIONS (TIGHTEN) INCLUDING BRACING

5. GROUT COLUMN BASE PLATES


FIRST COLUMN

This is the first column being hoisted into position. Using ladders, iron workers temporarily bolted the column. Prior to erection, the erector must consider column stability in accordance with safety standards and the AISC Code of Standard Practice.


SEQUENCE COLUMN


BEAMS

Main girders are hoisted after the columns. Beams are then hoisted and connected to the girders.


PRILIMINARY BOLTING

The connector uses pins to align the holes between structural steel members being connected. Then several bolts are placed and temporarily tightened with spud wrench. At least two bolts per connection are used to temporarily fasten each connection.


HAND SIGNALS

Teamwork and communication are important when erecting steel. Iron workers use hand signals to communicate with the crane operator.


PLUMBING

Turnbuckles are a common part of the bracing system. A turnbuckle is a device that usually consists of a link with screw threads at both ends that is turned to bring the ends closer together. Using several turnbuckles connected to the temporary bracing, the steel frame is shifted until it is vertically aligned.


METAL DECKING

This is a view (right 1st image) of the welding used to fasten metal deck to the structure.


PERIMETER SAFETY CABLES

On multi-storey structures, perimeter safety cables are installed at the interior and exterior perimeters of floors and openings as soon as the metal decking has been installed.


SHEAR STUDS

This is a view of the welded studs. Shear studs are tested to ensure that they are correctly welded to the structural steel members in compliance with the bend test of the AWS D 1.1 Structural Welding Code.


TEMPORARY BRACING

Temporary bracing is used to provide temporary lateral stability to the structure and to plumb up the frame. The temporary bracing is removed once the structural steel frame is secured.


FINAL BOLT UP

After a section of the structural frame is assembled and vertically aligned, iron worker permanently fastens the structural steel members with additional bolts. Tension controlled black bolts of SS 8.8 grade are widely used. Final bolt-up is performed using a torque wrench. The wrench stops automatically when the bolt shears at a tension control groove indicating that the required tension is reached.


SLABS

Floor slabs are poured after the structural steel frame is secured to the vertical masonry shafts. After reinforcing steel and concrete is placed, the slab is leveled and finished.
