Manufacturing technology and safety and environmental protection measures of metal handrails with railings

The global population is slowly increasing, which also makes the per capita land use decrease, and people have to build various high-rise buildings. Stairs play the role of connecting all floors in the building. With the rapid development of science and technology, stairs have become intelligent. There are common stairs and electric stairs in our lives. No matter what stairs, there will be handrails with railings. We usually see a variety of handrails with railings. Today, I will take you to know about metal handrails with railings.

manufacturing process

(1) All handrails shall be manufactured according to the design requirements of the drawings and the patterns shown in the drawings and the actual specifications and dimensions on site.

(2) Indoor stairs and balcony railings need to be fabricated and installed on site. Before materials enter the site for fabrication and installation, they should be painted with antirust paint twice. During the fabrication process, the positioning size should be accurate, the bevel angle should be cut and the ground mouth should be ground to ensure accurate and fine angle assembly. When assembling, the welding parts should be welded flat, and the butt joint parts should be tight to ensure the flatness. The joint of the welding part must be fully welded, so that there is no broken seam and trachoma in the joint, and the joint should be polished and smooth, and the flatness is up to standard. Steel handrails should be polished and ground, and installed on site under the condition of ensuring pollution-free construction site.

(3) Stairs, balconies, balconies and entrance railings shall be made, and rust removal shall be achieved without rust or trace. After completion, inspectors shall conduct inspection according to the requirements of drawings. The finished products require smooth and clean surfaces, and the overall effect is beautiful and elegant. Be careful not to scratch or damage them during installation.

(4) arrangement of construction personnel. 1 project leader, 1 technical leader, 4 welders and 6 sewing workers. Main machine arrangement: 4 electric welding machines, 4 angle grinders and 4 electric hammers.

Safety and environmental protection measures

(1) Before painting construction, workers should be concentrated to carry out safety education and make written disclosure.

(2) It is forbidden to set up a paint material warehouse on the construction site, and the paint warehouse outside the site should have sufficient fire control facilities.

(3), the construction site should have no fireworks safety signs, the site should set up a full-time security officer to supervise and ensure that there is no open flame on the construction site.

(4) Water shall be sprayed by designated personnel for site cleaning, and there shall be no dust pollution. Wipe the grinding dust with a damp cloth.

(5) When painting, operators should wear corresponding protective facilities, such as gas masks, masks and gloves. So as not to harm the lungs and skin of workers.

(6), it is strictly prohibited to use organic solvents to clean construction equipment in civil construction engineering rooms.

(7) After use, the paint should be stored in a timely manner, and the waste should be cleared out of the room in time. During construction, the room should be well ventilated, but it is not advisable to have a draught.

technical quality assurance measures

1. Material requirements. All materials and finished products must have a material list and a certificate of approval.

2. Before the construction personnel take up their posts, they should be educated in professional technology and safe and civilized construction according to their different jobs.

3. In the construction process, technicians will check and correct the illegal operation on the construction site in time. Put forward quality change list and quality problem change measures to ensure the engineering quality to meet the design requirements and acceptance specifications.

4. Strictly implement the engineering quality standards. The variety, specification, model and thickness of materials must meet the engineering and design requirements. The welding joint should be fully welded, polished smoothly and flat, and the paint should have no tears, strong brightness, clean surface, beautiful appearance on the above table, accurate production size, horizontal and vertical products, and meet the design requirements and acceptance criteria.

Although metal handrails with handrails are common facilities that are usually seen, great attention should be paid to their safety. The function of metal handrails with railings is to help people walk, especially the elderly and children. Because they are inconvenient to move, they often have to hold the handrails with railings when walking. If the quality of handrails with railings cannot be guaranteed, they will accidentally fall down when walking, which is a very serious matter. So remind everyone to be careful when going up stairs.
