隨著人們審美的提高，越來越多的人選擇用GRC材料來進行裝飾，那么你們知道
濟南GRC構件與建筑物的連接點的安裝事項是怎樣的嗎？
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）當GRC構件自重小于25kg時，安裝連接點不少于4個，采用上下后左右連接；當GRC構件自重大于25kg時，每增加10kg，應少增加兩個連接點；連接點間距不得大于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）采用焊接方式連接時，焊接鋼筋時，雙面焊縫長度不應小于5倍鋼筋直徑，單面焊接焊縫長度不應小于10倍鋼筋直徑。焊縫高度不小于3㎜，焊縫等級不低于二級，禁止使用點對點、點對面的焊接方式。
(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）裸露于空氣中的連接件及焊縫應進行防腐處理。
(3) The connectors and welds exposed to the air shall be subject to anti-corrosion treatment.
此外后錨固連接點固定方式為，建筑物連接結構為現澆混凝土結構，實際強度等級大于C20級，厚度大于1.5hef(hef為有效錨固深度不應小于50mm)，且大于100mm時采用，直徑不低于8mm的錨栓，或膨脹螺栓，不符合上述要求時，應采用焊接連接方式安裝。
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.
建筑物連接結構為空心塊狀砌體結構，砌體強度大于Mu7.5，砂漿強度大于M5，砌體厚度大于等于370mm采用置換塊，置換塊應采用C20級以上膨脹細石混凝土灌注，厚度240mm高度和寬度不小于240mm，錨栓應安裝在置換塊中心位置，不符合上述要求之一時，應采用焊接連接方式安裝。
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.luxuryofwatches.cn Consult!
