when the keel pavement moisture content is too high, and gradually reduce the moisture content after drying, nail holding power while reducing timber, loose keel installation; 3,can wpc be cut with normal tools the moisture content is too high concrete base, not pavement moisture barrier layer or moisture barrier layer No overall sealed so that the keel moisture absorption, increased moisture content, distorted, loose keel installation; 4, keel material density is too low or too small cross-sectional area resulting in insufficient nail holding power, nails diameter is too small, too short, keel pavement flatness does not meet the requirements, resulting in lack of firmness installation;
wood tongue and groove wood flooring due to climate change when the swelling shrinkage, tongue and groove out, does not work, too tight friction when the swelling; 6, excessive drying of the climate make wood floors, nail holding power weakened keel between tongue and groove wood flooring loose connections, excessive humidity make wood flooring lateral expansion, composite replacement slats for benches resulting in a slight squeeze expansion bagging, fixed keel so loose, so that the same nail holding power weakened; 7, the installation process is not standardized. Preventive measures: 1, pre-construction check the flatness of the concrete base and trimmed to meet the requirements before continuing construction;
pre-construction check the moisture content of the concrete or soundness moisture barrier layer; 3, the cross-sectional dimensions and inspection keel moisture content; 4,plastic balcony fence Supplier the larger the contact keel pavement concrete grassroots area, installed more securely, bolster part, the higher the pillow, the more prone to loose.
Solution: hidden project construction conditions and to strengthen the inspection, to ensure flatness and good moisture barrier layer of the
concrete base; such as excessive moisture or when excessively dry climate, to be observed only when the weather normally occurs. If there is no obvious sound, you do not need trimming. Question 4: Alice bending deformation, surface phenomena: the wooden floor on both sides of the lateral tilt upward, like a tile-like.
Analysis: 1, the concrete wall near the moisture content or the moisture content is too high; 2, the construction of the concrete base has splash, mixed with aqueous material, how much to build a deck calculator resulting in increased moisture content of the concrete base; 3, did not seek to take water, moisture barrier isolation off measures; 4, keel moisture content is too high, the water is evaporated on the back of the absorbent wood flooring; 5,
