60 series of light steel keel, 12 thick single layer of paper gypsum board "which" 60 series light steel keel "What is the meaning of the project. Is the main keel, vice keel are 60 series? Or only refers to the main keel 60 series, vice keel 50 series? Thank you
Quality identification of light steel keel
??Light steel keel according to the use of hanging keel and cut keel, according to cross-section of the form of V-type, C-type, T-type, L-keel.
(1) product specifications series
?The main specifications of the keel are divided into Q50, Q75 and Q100.
The main specifications of the ceiling keel are divided into D38, D45, D50 and D60.
(2) product marking method
Light steel keel mark the order of the order: product name, code, cross-sectional shape of the width, height, plate thickness and standard number. Such as cross-sectional shape of "C" type, width of 50mm, height of 15mm, steel plate thickness of 1. Smm of the ceiling keel marked as: building light steel keel DC 5 0 XIS XISGBllg sl
(3) appearance quality
Light steel keel shape to smooth, angular, cut not allowed to affect the use of burrs and deformation. Galvanized layer is not allowed to skin, from the tumor, shedding and other defects. For corrosion, damage, dark spots, pitting and other defects, according to the provisions of the method should be tested in accordance with the provisions of Table 2-81.
?Appearance quality inspection, should be 0.5m away from the product under the conditions of bright light, the visual inspection.
?Light steel keel surface should be galvanized rust, the double-sided galvanized: excellent products not less than 120g / m * m, first-class goods is not less than 100g / m * m, qualified products not less than 80g / m * m.
60 series light steel keel refers to the D60 series of ceiling light steel keel, are generally 60 main dragon with 50 pay dragon, which has to meet the requirements of the Master, there are 60 to pay the dragon, but only for special design requirements, must Less use.

Construction Technology of Light Steel keel
? 1) construction sequence; light steel keel installation of the construction sequence: wall line - → wall construction - → installation along the ground, along the top keel - a → installation of vertical keel (including the door to strengthen the keel), crossed keel , Through the keel - → a variety of hole keel reinforcement.
? 2) construction points
① in the edge, along the top keel and the ground, the top of the contact with the laying of rubber or asphalt foam, and then according to the provisions of the spacing with nails (or drill with electric drill eye plug expansion bolt) will be along the edge, along the top keel fixed On the ground and the top.
② nail from the distance of 0.6 ~ 1.0m spacing arrangement, the horizontal direction of not more than 0.8m
, The vertical direction is not greater than 1.0m. The best depth of the shot shoot base: the concrete is 22 ~ 32mm ~ brick wall for 30 ~ 50mm.
? ③ will be cut in advance the length of the vertical keel, to the horizontal along the top, along the keel, the flange toward the gypsum board direction, vertical keel upside down can not be reversed, the scene can only cut from the top cut, vertical Long keel can be used long U-shaped keel sets in the C-keel joints, with a rivet or self-tapping screws.
