What are the effects of GRC products in exterior decoration?

Beijing Longyuan Decorative Materials Co., Ltd. Tell you what effect GRC products can play in exterior decoration?

GRC product components prevent construction cracks

Most of the GRC product lines are made of 1.5 to 3 meters/root in exterior decoration, and use a plurality of connecting devices to outline the effect of the exterior wall. On the one hand, due to its heavy weight, the device is not evenly loaded, and is affected by its own weight. Cracks occur between adjacent joints; on the other hand, the lines are connected by multiple connections at the time of installation, and the joints are mostly treated with 1:2 cement mortar in the construction process, and the coefficient of thermal expansion is different from that of GRC cement products. The formation of cracks; GRC line device again, especially in the horizontal line without expansion joints, when the temperature changes in the joint was pulled or cracked, and cracking occurred.

Satisfactory construction requirements

GRC line device on the external wall, generally according to the device diagram provided by the manufacturer, install 8 ~ 10 general expansion bolts on the external wall, and then use the standard 6 steel rebar and embedded steel reinforcement welding, or direct expansion bolt placement convex Blocks, window tops are fixed on the wall. In the above method, the method of spot welding is generally used in construction. The length of the weld cannot meet the requirements. After the bolts are struck by the wall, they are simply hit in the brick seams, and the effect cannot be achieved. The requirements of the "Regulations" pose a danger to the installation of GRC lines.

Prevent safety hazards

In order to prevent the position of the GRC components in the embedded reinforcing steel frame from proceeding in the direction of reinforcing steel corrosion and large cracks, the GRC component embedded skeleton steel reinforcement and embedded parts shall be treated with galvanized steel bars or stainless steel bars or other anti-rust treatment to prevent corrosion. Swelling cracks eliminates safety hazards.

In general, the steel bar generally plays the role of bearing pressure, tension, shear force, etc. The stress of the steel bar is generally equipped in columns, beams, and plates. The equipment of the steel bar is different for different forces. Therefore, it is necessary to select Be extra attention. Because there are many types of steel bars in the market, the general chemical composition of steel bars can be classified into carbon steel and general low alloy steel according to the classification. The nature of the steel bars is not the same, and the steel bars required in GRC components have high strength and good resistance. Mainly, so you must choose according to your needs.
