Wind pressure resistant SQ-Bar System

AL tile system which is most generally used as indoor/outdoor ceiling of building architecture adopted clip-in fixture method. Therefore there was fear of falling off when used to external canopy and pilotis. Wind resistant SQ-Bar System being developed by Yoochang adopted screw fixing method thus sturdiness was improved and securing wind resistance function. Thus possible to assure beauty by forming 15 mm or 20 mm Joint Line.

Special feature of SQ-bar system (for resistance against wind pressure)

* Firm fixing to high ceilling difficult for checking such as external canopy/piloti and lobby of building architecture etc.
* As wind pressure resistant structure securing highest efficiency against wind pressure
* High productivity and economy through production method same as that for AL Tile.
(1) Set up centerline of building; Set up center line by checking other work process such as light line and location of diffuser etc. after carrying out precise survey of ceiling.

(2) Installing molding for preventing falling off
    ① After checking height of ceilling according to drawing carrying out marking by using level.
    ② Along the marking install molding for preventing falling off and install piece or framing nailer pin at an interval of 300∼600mm.
    ③ At the time of installing finishing material as per Paragraph (9) panel for fringe shall be made at the site and place it on molding and prevents falling off by pressing down 2 SUS fixing clips per piece.

(3) Strong anchor work
    ① At the time for strong anchor work; When centerline is set mark the part for fixing strong anchor (9mm) at slab face and drill hole then fix it.
    ② It is ideal to make interval for its installation as @900∼1,200 mm in consideration of direction of installing SQ-bar(upper part0
    ③ Note; It is required to pay attention to interval between anchor or insert and right angle. After installation each piece shall withstand uplift load of 100kgf or more. After embedding insert independently to slab install ceiling hanger bolt.

(4) Installing wind pressure resistant bolt
    ① Fix the upper part of wind pressure resistant bolt to strong anchor or insert and fix lower part of bolt with hanger and nut in consideration of ceiling height.
    ② At the place where installation duct and other obstacles are present work shall be carried out after reinforcementaccording to drawing and specification.

(5) Attachment of SQ-runner
    ① Attach SQ-runner along ink-pot string and SR-runner shall be fixed at an interval of @500∼1,000mm by using 1" concrete nail.
    ② Be careful not to slacken height and gap between SQ-runner and SQ-runner.
    ③ Attach it according to specification in connection with installed pieces such as curtain box etc.
    ④ Caution; If not indicated on the drawing SQ-runner may be omitted.

(6) Installation of lightline
It shall be done according to specification for installation of lightline but consultation with persons related to electricity and installation shall be required.

(7) Installation of SQ-bar (upper part)
Hanger set and SQ-bar are tied by piece and fixed and shall be installed within @1,200 mm.
The connection part of SQ-bar shall be connected by SQ-bar joint.
SQ-bar shall be installed in a way not to be away more than 30 cm from wall or curtain box side.

(8) Installation of SQ-bar (lower part)
    ① Install SQ-bar after placing string at centerline of the work sturdily by using SQ-bar clip with piece at right angle direction to SQ-bar (upper part) according to dimension of the product and along the light line.
    ② Installation interval of SQ-bar (lower part) shall comply with drawing or specification. When it is not recorded at drawing or specification then install it within 450 mm.
    ③ SQ-bar (lower part) shall be installed by inserting it to SQ-runner or curtain box wing.
    ④ Level of installed ceiling frame shall be maintained accurately by water level or using level device.
    ⑤ Note: At the time of using ceiling hanger bracket then with approval from supervisor SQ-bar (upper part) may be omitted.

(10) Installation of finishing plate
    ① Finishing plate is fixed with piece to SQ-bar.
    ② Line of finishing plate shall be straightline and there shall be no gap at joint part.
    ③ Finishing place shall comply with drawing.

(11) Installation of curtain box
    ① Depending on specification products suitable to purpose is manufactured and installed.
    ② Welding work is carried out concurrently thus install work bench enabling work in safe and convenient stance.
(1) Handling and storage of the product
① Store it in a condition with relative humiditiy of 80% or less.
② To prevent any damage from water or moisture always keep it at dry and clean place.
③ Be careful not to damage corners
④ Maintain certain space from the wall surface and place spread sheet and then lay down water-proof sheet then preserve it.

(2) Environmental condition at the time of carrying out the works
① At the time of works temperature of 30℃ or less and relative humidity of 80% or less shall be maintained.
② The works shall be commenced after completion of joiners' works.
③ Before. during and after the works air-conditioners shall be operated so that proper level of indoors temperature and relative humidity are maintained.
④ The works shall be commenced after completion of all the papering and painting walls and ceiling.

(3) Caution at the time of carrying out works
Pipe-layng and electric works shall be completed before installation of SQ-bar installation and then works shall be carried out.

(4) Conditions for carrying out works
① The contractor for the works shall consult with the client with sufficient consideration of site conditions.
② While carrying out works at the time of appearance of any problems works shall be continued after sufficient consultation with the client.
③ As much as possible ceiling plan intended by the designer shall be observed.
