1. Key points of railing construction
1. Some railings can be installed on the ground;
2. When installing, pay attention to protect the surface of the wood plastic material from being scratched;
3. When installing, ensure the beauty while ensuring the strength, and pay attention to the position of the screws;
4. For railings with radian requirements, the angle of the tenon needs to be calculated;
5. Pay attention to the beauty when installing the flower plate of the railing, and try not to expose the screw holes;
6. Use glue when installing the hat;
7. For railings with radian requirements, pay attention to symmetrical transitions;
8. The characteristics of thermal expansion and contraction of wood plastic should be considered when tenoning, leaving room for expansion and contraction;
9. When installing the column and the road ground, steel plates can be embedded in the concrete, and the steel plate at the bottom of the column can be welded with the embedded steel plate or fastened with bolts;
10. When the total length of the railing is greater than 300 meters, consider adding a deformed transitional column; 11. The style of the railing, the specifications of the selected profile and the span of the railing should be closely matched.
Two, the key points of floor construction
1. The load-bearing capacity must be calculated before floor construction;
2. Some places that need to be reinforced can be reinforced with concrete tie beams and steel;
3. Be careful not to damage the original concrete structure when using steel for reinforcement;
4. The distance between the keels should be calculated accurately;
5. The keel should be leveled;
6. The keel and the ground should be fastened with expansion screws;
7. The effect of burying the keel in concrete is better;
8. It is necessary to reserve a drainage channel;
9. Considering that wood plastic has the characteristics of thermal expansion and contraction, expansion joints should be left horizontally on the floor;
10. Use stainless steel screws to fasten the floor and keel;
11. Expansion joints should also be reserved in the longitudinal direction of the floor, and the size of the gap should be reasonably designed according to the temperature in use, the expansion coefficient of the material, and the length of the material;
12. The plate shall be fastened with 2 stainless steel screws and keel;
13. Because wood plastic has the characteristics of slight thermal expansion and contraction, and considering cleaning and other reasons, when wood plastic profiles are installed, there must be a proper gap between the edges and the ends;
14. When installing wood-plastic floor, it is best to install the profile on the keel;
15. When there is an inclination between the profile and the keel, or if it is installed in the bath, please reduce the distance between the keels at least 10 cm.
