1. Check whether the specifications of the wooden keel meet the design requirements (generally, it is better not to be less than 5 cm × 3 cm, generally it is better to be 30 cm × 30 cm);
2. Check whether the spacing of wooden keels meets the requirements for the installation of wooden floors;
3, check whether the wooden keel loose phenomenon (can step on a step);
4. Check if the plane on the wooden keel is flat (use 2 meters by the ruler);
5. Check whether the gap between the wooden keel and the ground is replaced with a wood wedge instead of a wooden block;
6. Check whether the length of the nails used in the fixed wooden keel can meet the requirements of long-term use, and no loose phenomenon will occur;
7. Check whether there is a telescopic gap at the junction of the wood keel and the wall (to avoid moisture deformation).
Tip: Some people believe that solid wood flooring is prone to deformation and its service life is relatively low. However, if it meets the above acceptance requirements, the service life will be greatly enhanced.
Ground acceptance
Self drilling Screw made of 410 stainless steel, high hardness (40 Rockwell C), steel process.
Drilling screw is also very strong hardness, compared to the ordinary screw up, not only to maintain the ability is good, the connection object effect is also very strong, for the performance of the screw, are generally does not need auxiliary processing, can be directly on the object directly drill a Kong Sue into objects, not just use rise very convenient, Also can greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of workers in various fields.
So what is the use of drilling screws?
1 stainless steel plate, metal plate, galvanized steel plate, engineering installation.
2 metal curtain wall metal light compartment and other indoor and outdoor installation.
General Angle steel, channel steel, iron plate and other metal materials combined installation.
4, automobile, container, shipbuilding, refrigeration equipment and other assembly projects.
