The construction of a layer of hanging stone in a villa generally adopts angle steel + corner hanging, and the second layer adopts channel steel + angle steel + corner. The podium basically adopts channel steel dry hanging + sealant processing. And the use of corners is relatively small. The safety coefficient of dry hanging channel steel is the highest, decreasing in turn. Here's a look at dry marble steps and dry marble safety assurance measures.
Dry hanging marble steps
1. Measure to determine the location, use electric drill to drill holes in the wall.
2, four expansion screws.
3. Use a hammer to tap the expansion screw into the previously calibrated hole.
4. Use a spanner to fasten the fasteners.
5, check the fastener is completely fixed.
6, the expansion screw distance to be determined according to the size of the marble.
7. The marble is leaned against the fastener. The previously applied marble glue will stick to the marble, and the slot can be set.
8. Slot at the location where the glue sticks to marble.
9. Apply a large amount of marble adhesive after opening the groove. On the grooved surface, it is polished to increase the adhesive fastness of the rough surface.
10. Apply glue. 
11. Fix the marble after adjusting the level.
12, finished product, the effect is not bad.
Dry hanging marble safety assurance measures
1. Timely and targeted safety technology for construction personnel shall be implemented.
2. Sign economic contracts and safety production agreements with subcontracting construction units and professional construction companies.
3, on-site construction personnel after three levels of safety education, after passing the exam can be post jobs.
4. The use of ladders must be solid and must not be lacking. The ladder should have a stable rope and a firm support, with anti-slip measures on the ground.
5, the use of wooden stools to be solid and reliable, stable corners and the ground, is strictly prohibited for more than two people standing with a stool, a ladder.
6. Personnel entering the construction site must wear a safety helmet and tie a cap.
7, high-altitude workers dressed, easy to wear hard bottom and nail slippery shoes.
8. Workers should not disperse construction wastes at will and must not throw any debris from high altitudes.
9. Persons suffering from heart disease, epilepsy, hypertension, anemia and other diseases are strictly prohibited from engaging in construction operations.
10, strictly in accordance with the safety operation procedures, special types of jobs must hold valid credentials, non-type of work can not engage in special operations.
11. During working hours, you must not drink alcohol, smoke, play slapsticks, and concentrate on sticking to your job.
12. The construction site must use three-phase five-wire power supply.
13, all electrical equipment, facilities must be zero, grounding protection, protection zero, ground contact solid and reliable.
14. Rubber cable should be used for cables. Overhead protection must be protected. The brakes in the electrical box should be intact, sensitive and effective, and the inside of the box should be clean.
15, the use of electrical machinery, power tools, lighting, etc. must be installed leakage protection device, leakage protection device to be sensitive and effective.
16, the use of electrical machinery, electrical equipment, power tools, etc. must be implemented "one machine and one brake" control, is strictly prohibited "a brake multi-machine" use.
17. The welding machine shall be equipped with a separate control switch. The first line shall not exceed 5 meters in length. The two ends shall be firmly connected and the enclosure shall be protected by zero or grounding.
18, welding machine should be double line in place, the line skin should be intact, to ensure good insulation.
19. Electricity is used at the construction site. It must be operated by a professional electrician. It is forbidden to use this type of work.
Editor's summary: The dry marble steps and dry marble safety assurance measures are introduced here, and we hope to help everyone. Want to learn more related knowledge can focus on this site information.
