OUTCORNER Attached member in/out-corner where SLAB and WALL meet each other 1.2 List of Names and Usage PROP HEAD (PH) Supports the weight of E/B and Slab Panel which is reserved until Concrete is completely dry (Remained until Floors are completed) MIDDLE BEAM (MB) Connected by Slab Panel and Slab Panel and it is placed between P/H and P/H END BEAM (EB) Connected by Slab Panel and Slab Panel and it is placed between P/H and SC or P/H and Slab Panel 1.2 The Name of items and Usage JOINT BAR Used to joint End Beam, Middle Beam and Prop Head Special PROP HEAD Used where Prop Head cannot be used which supports the Slab concrete until it is dry (Remained until Floors are completed 10 SLAB PANEL Light and firm Panel made of Aluminum with special coating used for Slab which produces an excellent frame shape AL FORM’s Features Manufactured and used similar as to Euro-Form but roundshaped for precision Assemble Wall and Slab by Slab corner, monolithically Support is the Pre-Shoring System which requires set of Formwork; Reserve shoring for sets To change the height of floor, extension form is available to assemble with ease Used with Rocker to straighten root ground to reduce labor workers Triangular Pin (Wedge Pin) Round Pin (Φ16) K-AL FORM SYSTEM Assembling of materials END BEAM(EB) SLAB CORNER SLAB PANEL PROP HEAD MIDDLE BEAM(MB) JOINT BAR SUPPORT WALL PANEL 4.2 COMPARISON of the DETAIL ITEMS Linking SECTION EURO FORM AL FORM LINKING LINE LINE DESCRIPTION Joint line of Plywood and Frame (Rivet mark ) FRAME & SHEET in monolith, only JOINT Line remains 4.2 The Description of Detail Items CON’C Condition Section AL FORM EURO FORM CON’C Condition Working on concrete surface is much smaller Working on concrete surface is too much Description Formwork surface is Plywood (Coating is applied) CON’C & AL FORM surface quality lowers when oxidation occurs 4.2 Detailed Item Description CHAMFER (Features) Intersection Part (Balcony) Section EURO FORM AL FORM CHAMFER (Features) Welding of Steel Panel AL FORM CHAMFER Setup Falls off due to thin welding Surface of Steel Form is slippery but crack occurs Description Surface is slippery and less falling off Crack No Crack 4.3 OTHERS EURO FORM Advantage ☞ Changeable Plywood available depending on floor ( Cost Reduction ) (TEGO P/W – Low Floor, Woodstock– High-rise BLDG.) ☞ Low heat transmission ☞ Cheap Form oil ☞ Form Oil applied less damage in structures after rain ☞ Water prevention part handled at site ( Plywood available ) ☞ (Used Times at Site) Frame and Plywood shape is changed after one time use (Low Durability) ☞ Hard to put together if frame is fallen off and bent (Low Elasticity) ☞ Wasted plywood occurs (Polluted Environment) Disadvantage ☞ Number of used times is limited in a single site (15Times) ☞ Waterproof cut surface of plywood needed ☞ Elasticity is low that in narrow area conventional filler is needed ☞ More cracks take place AL FORM ☞ Higher Durability ☞ Low concrete finishing work.(Form Oil is Necessary) ☞ High elasticity ☞ Environment friendly and reusable ☞ Number of used times is less limited in a single site ( 120-150 Times ) ☞ Low bending when welding ☞ When Water prevention part is broken exchange work is slower ☞ High heat transmission (High temperature rise in summer) ☞ Expensive Form oil ☞ Form Oil applied more damage in structure after rain ☞ High priced raw material ☞ Welded and Chamfered materials are harder to discompose at site ☞ Especially in winter, the Al-form and concrete tend to fall lit bit K-AL FORM SYSTEM SAMPLES OF SETUP

delivery of materials (Within 50~60 Days Conformation) 2) After confirming structure drawing, it is sublated for structure drawing 3) Importance check list of Structure drawing ▣ Position of dew condensation & Width Size ▣ Entrance Door Height & Conform Door Opening ▣ Check of Extended Waterproof & Balcony ▣ Check if Architectural Drawing, Structural Drawing correspond 4) IMPORTANCE check list OF AL FORM DRAWING ▣ Confirming Standard Detailed Section Drawing ▣ Confirming TIE Position & Quantity ▣ Check different part with Structural Drawing ▣ Confirming Input Range & Delivered Goods Preparation 1) Delivery Schedule & Work Chart 2) When Assembling & Disassembling Al-form, aware of warnings and check points 3) Prepare AL FORM PLAN drawings (Final confirmed drawing) 4) Supplier & check A/S staffs’ contact number 5) Secure place for accessories (Tie, Pin…) Additional Labor Plan : Stair Team, WALL+ SLAB Team, Goods Lift Team, and ETC… Proper Staff Secure Plan K-AL FORM SYSTEM K-AL Form System Applied Effects & Management Check List Applied Effects ▣ Material Innovation - Precise construction is available until the top floor - Reduction of reconstruction & errors - Used high class materials without any workers’ skills ▣ Cost deduction in overall construction - Deduction on plastering costs of inner & stairs - Deduction on Scrap & readjustment costs ▣ Reduction of construction period - Deduction of disassemble time and lightweight compared with Euro from - Disassemble of Slab Form with Support still used - Overall deduction of construction period by finishing the end of construction ▣ Improvement of Working Area - K-Al Form is 100% reusable - Clean site without Plywood, Timber, wood - Very little dust due to reducing talcum ▣ Improvement of industry safety - Safety management with clean site - It is easy to ensure working area for working safety ▣ Improved labor workers - More skilled labor workers - Special workers not needed Management Check List ▣ Every floor spread with Form Oil thoroughly (At least floors) Used after removal (Cement & Aluminum) ▣ Notice Strong Vibration, it occurs in air bubble during curing ▣ Check whether it inserts upper side pin (Causes defect of Molding) ▣ Flatness by checking Slab Concrete (LEVEL) surface ▣ Check for bending of Long Span wall bending when installing the slab form ▣ Because of carelessness management, it occur in damaged materials ▣ Basement, Piloti, roof house not usable( By site) ▣ Specific instructions and work knowledge to all workers Thank you! ...CONTENTS K -AL Form System Outline
