GRC構件轉角、邊口處應設置不低于?4 的通長連續(xù)刻痕鋼絲加強;幾何尺寸大于400 mm 的GRC構件應配置鋼筋網(wǎng),其鋼筋直徑不小于?6、間距不大于400 mm。
GRC component corners and edges shall be set at not less than? 4) reinforcement of full-length continuous scored steel wire; GRC members with geometric dimensions greater than 400 mm shall be equipped with reinforcement mesh, and the reinforcement diameter shall not be less than? 6. The spacing shall not be greater than 400 mm.
GRC構件幾何尺寸不宜超過1000mm,當超過1000 mm時,鋼筋的直徑和間距由結構設計確定.鋼筋保護層厚度不應低于15mm;構件肋部(只有鋼筋部位的幾何尺寸應不應小于6d(d為鋼筋直徑,下同),并加設耐堿玻璃纖維網(wǎng)格布,網(wǎng)格布寬 200mm.GRC構件小壁厚不宜小于8 mm;頂面的寬度大于300 mm 時,小壁厚不宜小于30 mm。
The geometric dimension of GRC members shall not exceed 1000mm. When it exceeds 1000mm, the diameter and spacing of reinforcement shall be determined by the structural design. The thickness of reinforcement protective layer shall not be less than 15mm; The geometric dimension of member rib (only the reinforcement part) shall not be less than 6D (D is the reinforcement diameter, the same below), and alkali resistant glass fiber mesh cloth shall be added, with the mesh cloth width of 200mm. The minimum wall thickness of GRC member shall not be less than 8mm; When the width of the top surface is greater than 300 mm, the minimum wall thickness should not be less than 30 mm.
GRC構件的預留連接件一般采用預留鋼筋或預留錨板兩種方式：
The reserved connectors of GRC members generally adopt two methods: reserved reinforcement or reserved anchor plate:
(1)當 GRC 構件較小時(大尺寸小于 600 mm,且自重小于25kg),可直接將構件配筋外露,外露長度應大于10d 且滿足焊接要求;
(1) When GRC members are small (the maximum size is less than 600 mm and the self weight is less than 25 kg), the member reinforcement can be directly exposed, and the exposed length shall be greater than 10 D and meet the welding requirements;
(2)當 GRC 構件較大時(大幾何尺寸大于等于600mm,或自重大于等于25kg),應預留錨板,錨板應采用強度不低于Q235級鋼,錨板的厚度應不小于構件配筋直徑的0.6倍,錨板鍍鋅層的鍍鋅含量不小于350g/㎡; 錨栓或鋼筋穿孔中心錨板邊緣的距離 D不應小于 2d 或 20 mm,穿孔與鋼 筋之間的大間隙不應大于 2 mm..鋼筋與錨板延穿孔周邊雙面滿焊.
(2) When GRC members are large (the maximum geometric size is greater than or equal to 600mm, or the self weight is greater than or equal to 25kg), anchor plates shall be reserved. The anchor plates shall be made of steel with strength not lower than Q235. The thickness of anchor plates shall not be less than 0.6 times the diameter of reinforcement of members, and the zinc content of zinc coating of anchor plates shall not be less than 350g / ㎡; The distance d from the center of the anchor bolt or reinforcement hole to the edge of the anchor plate shall not be less than 2D or 20 mm, and the maximum gap between the hole and the reinforcement shall not be more than 2 mm. The reinforcement and the anchor plate shall be fully welded on both sides along the periphery of the hole
