随着人们审美的提高，越来越多的人选择用GRC材料来进行装饰，那么你们知道
济南GRC构件与建筑物的连接点的安装事项是怎样的吗？
With the improvement of people's aesthetics, more and more people choose to use GRC materials for decoration. Do you know what is the installation of connection points between GRC components and buildings in Jinan?
（1）当GRC构件自重小于25kg时，安装连接点不少于4个，采用上下后左右连接；当GRC构件自重大于25kg时，每增加10kg，应少增加两个连接点；连接点间距不得大于400㎜.
(1) When the dead weight of GRC component is less than 25kg, there shall be no less than 4 installation connection points, which shall be connected from top to bottom, left to right; When the dead weight of GRC component is more than 25kg, at least two connection points shall be added for every 10kg increase; The distance between connecting points shall not be greater than 400 ㎜
（2）采用焊接方式连接时，焊接钢筋时，双面焊缝长度不应小于5倍钢筋直径，单面焊接焊缝长度不应小于10倍钢筋直径。焊缝高度不小于3㎜，焊缝等级不低于二级，禁止使用点对点、点对面的焊接方式。
(2) When welding is used for connection, the length of double side weld shall not be less than 5 times of the rebar diameter, and the length of single side weld shall not be less than 10 times of the rebar diameter. The weld height shall not be less than 3mm, and the weld grade shall not be lower than Grade II. Point to point and point to face welding are prohibited.
（3）裸露于空气中的连接件及焊缝应进行防腐处理。
(3) The connectors and welds exposed to the air shall be subject to anti-corrosion treatment.
此外后锚固连接点固定方式为，建筑物连接结构为现浇混凝土结构，实际强度等级大于C20级，厚度大于1.5hef(hef为有效锚固深度不应小于50mm)，且大于100mm时采用，直径不低于8mm的锚栓，或膨胀螺栓，不符合上述要求时，应采用焊接连接方式安装。
In addition, the fixing method of the rear anchor connection point is: the building connection structure is a cast-in-situ concrete structure, the actual strength level is greater than C20, the thickness is greater than 1.5 hef (hef means the effective anchoring depth should not be less than 50 mm), and when it is greater than 100 mm, the anchor bolt or expansion bolt with a diameter of not less than 8 mm should be used. If it does not meet the above requirements, the welding connection method should be used for installation.
建筑物连接结构为空心块状砌体结构，砌体强度大于Mu7.5，砂浆强度大于M5，砌体厚度大于等于370mm采用置换块，置换块应采用C20级以上膨胀细石混凝土灌注，厚度240mm高度和宽度不小于240mm，锚栓应安装在置换块中心位置，不符合上述要求之一时，应采用焊接连接方式安装。
The connecting structure of the building is hollow block masonry structure. The masonry strength is greater than Mu7.5, the mortar strength is greater than M5, and the masonry thickness is greater than or equal to 370 mm. The replacement block shall be poured with C20 or higher expansive fine aggregate concrete, with a thickness of 240 mm and a height and width of not less than 240 mm. The anchor bolt shall be installed in the center of the replacement block. If one of the above requirements is not met, the replacement block shall be installed by welding.
Due to the particularity of the material itself and the manufacturing process, GRC component materials can be shaped arbitrarily according to the drawings. If you have relevant needs, please come to our website http://www.aswjc.com Consult!
