GRC is a kind of new building materials, before you is not very understanding this building materials, now with GRC component product exposure to improve, improve visibility, more and more people choice of GRC products to decorate his own house, the villa. Lanxi City three-dimensional art decorative elements of the GRC product design has many years of design and development and construction experience, the following to introduce the next, the GRC component of the installation of ten key steps.

1, the structure of the components to install the connection structure of the surface of the structure to deal with, to ensure its smooth, solid.

2, the surface of the component is missing edge off angle and other defects, after installation should be used to repair cement materials.

3, before installation should be according to the construction drawings on the wall of the bomb good standard of wire, horizontal, vertical, and the center member control line to control the GRC component mounted on the same horizontal line.

4, when the outer frame to take full account of the GRC line of the installation features and the outside size, ensure that the installation of GRC line when there is enough space

5, the component installation error should be in accordance with the following requirements;

(1) unit decorative surface verticality error less than 5mm/ height, and the total error is less than 50mm;

(2) unit decorative surface flatness error of less than 5mm/2m, and the total error is less than 50mm;

6, install the joint should be smooth, the error is more than 5mm, should be polished.

7, the component connection should be reserved gap, and according to the design requirements for processing.

8, there are parts of the waterproof requirements, should be waterproof treatment, and take the necessary measures to freeze damage. The links and welds exposed to air should be treated reliably.

9, after anchoring connection point fixation:

(1) building connecting structure for cast-in-situ concrete structure, actual strength grade more than C20, thicker than 1.5hef (HEF for effective anchorage depth should not be less than 50mm) and more than 100mm by, diameter of not less than 8mm bolt, or expansion bolt, do not meet the above requirements should be used when welding connection setup.

(2) building connection structure is a hollow block masonry structure and masonry strength greater than MU7.5. Mortar strength more than M5, masonry thickness greater than equal to 370mm using permuted blocks and block replacement should be the C20 above expansion of fine stone concrete pouring, the height and width of 240mm thickness not less than 240, the anchor bolt should be installed in the center of the replacement block, does not conform to the moment of the above requirements, should adopt welding connection setup.

10, component and building link points of the installation:

(1) when the GRC component weight less than 25, installation and connection point of not less than four, a post about connection: when the GRC component weight greater than 25 kg for each additional 10 kg should be increased by at least two connection: connection point spacing of not more than 500mm.

(2) the length of the two sides shall not be less than the diameter of the 5D bar, and the length of one side welding seam shall not be less than the diameter of 12D steel bar. The height of the welding seam is not less than 3mm, the welding seam is not less than two, which is forbidden to use point to point.

(3) in general building is a hollow piece of strong masonry structure or size of more than 400 (wide * 400) (high) of GRC component due to greater weight shall be embedded angle steel. Component reservation (diameter) phi 6 reinforced through 12 reinforced with angle steel welding and fixed GRC component, the horizontal direction of each 500mm a root (diameter) with a diameter of 12 reinforced, vertical direction along the GRC height two. (all steel welded parts shall be painted with anticorrosive paint).

(4) there is no pre buried installation angle of GRC components and in the installation of the corresponding structures to 45 degree angle implants (diameter) with a diameter of thread steel bar, the horizontal direction for each 500mm set a root, GRC along the height of two. By (in diameter) with 12 reinforced steel bar and GRC component in welding, thereby fixing the GRC component. (all steel welded parts shall be painted with anti rust paint)

(5) the connecting parts in the air and the welds shall be treated for corrosion protection.

After these ten steps, we should pay more attention to the maintenance, prolong the service life and the appearance of the appearance. Overall, the early work, the latter maintenance is not so much trouble, the builder or spend more time in the installation and construction, to reduce the maintenance of consumer.
