Planning of GRC board

GRC exterior wall decoration components are used for building construction and it is necessary to plan. Regarding new construction, GRC components should be included in the construction planning and structure planning. As for the old construction and renovation projects, special construction and structural planning must be carried out. It is forbidden to construct only on the basis of the elevation effect map.

The planning of GRC board includes:

1. Establish a plan for the establishment of a plan (ie, a plan for the use of components).

2. Component and construction connection node planning.

3, component planning.

The planning and use planning of GRC exterior wall decoration components must be in conformity with the national standards for construction and structure. Repair build surface planning and component selection The use of GRC exterior wall decoration components for repair and build surface planning is necessary to satisfy the following requirements:

1. Satisfactory requirements for the utility of the building.

2. Reconcile the environment with the site of the building.

3, beautiful, harmonious, consistent style.

4, the correct proportion, the right standard.

5. Skills are feasible and the device is convenient.

6, economic and reasonable.

It is necessary to give concrete construction plans and node diagrams for the establishment of a plan for the establishment of a plan (ie, a plan for the use of components). And conclude that:

1, component types, types, specifications, texture, color.

2, the parts and the number of components used.

3, the combination of components placed and joint methods.

4, components deal with the mouth.

Cross-connected components (eg twisted and waistline) shall determine the length of individual components, the method of jointing and the method of treatment at the corner, including:

1. Determine the gap where the components meet. Taking into account dry and wet deformation and temperature deformation elements, there is a need for expansion joints between horizontal connecting members. The length of the expansion joint of a single member not more than 2m in length is not less than 5mm. For a single piece with a length of 2m or more, the width of the expansion joint should be 5-10mm.

There are three ways to deal with gaps between components:

(1) Ming seam. Similar to real stone components, adhere to the natural joint effect.

(2) Semi-clear seam. Use rubber strips (or plastic strips) to seal seams and seal joints.

(3) The dark seam. Use rubber strips (or plastic strips) to seal joints, build sealants and then apply putty, brush paint, and make joints and components look the same.

Filler: Cement mortar must not be used for caulking in semi-emphatic seams and blind seams.

3. It is necessary to determine the length of each component according to the size of the axis of the building, the orientation of the doors and windows, the change of the corners of the wall, and the orientation of the expansion joints (settlement joints) of the wall so that the orientation of the joints of the components and the construction object can be established. Faces are harmonized with symmetry. And the size of the components is suitable for making and devices. The horizontal member length scale can be between 1.2-2.4m.

4. The horizontal members at the corners of the building shall be planned as yin and yang corner members, and the splicing shall not be carried out using the components. Yin Yang angle unilateral length can be between 0.3-1.2m.
