1. Technical preparations

Technical preparation Before the construction, the technical person in charge shall conduct the technical disclosure of the construction plan for each construction person in charge, and the construction team leader shall prepare the safety technical disclosure, and conduct the training and on-site operation guidance for the construction personnel.

2. Material preparation

According to the construction drawings and design requirements, purchase all kinds of raw materials required by the project. After determining that the material meets the design requirements of the drawing, the railing must be processed in the processing workshop to ensure that the unqualified material is not used on site.

3. Production process

(1) The railings are made according to the design requirements of the drawings and according to the drawings shown and the actual specifications and dimensions of the site.

(2) Do anti-rust treatment before the material enters the field production and installation. During the production process, the positioning size should be accurate and the grinding place should be ground. Ensure accurate and fine Angle assembly.

When assembling, the welding parts should be welded flat, and the butt parts should be tight to ensure the flatness. The welding joint of the welding part shall be fully welded, so that the welding joint has no broken cracks, missed welding, and no trachoma. The welding joint shall be polished and smooth, and the flatness shall meet the standard.

(3) The wall railing is processed for semi-finished products with steel wheel rust removal, and the surface is treated with rust prevention and then painted to ensure the cleanliness of the railing surface.

4. Construction personnel arrangement: everyone in charge of the project, everyone in charge of technology, welders, installation workers, paint workers.

Embedded parts and iron railing installation

1. Horizontal installation process

Wrought iron guardrail is installed in accordance with the standard line provided for the rail level standards.

2. Installation process

(1) After the product arrives at the construction site, it is accurately installed in place according to the position and size specified on the drawing, and the elevation and vertical flatness are determined. Positioning shall be carried out in accordance with Party A's requirements and drawing design requirements to ensure that design requirements and acceptance specifications are met.

(2) The installation of embedded parts is accurately positioned according to the design requirements of the drawings and the actual situation of the construction site to avoid being on a parallel line.

(3) The installation of the wrought iron guardrail shall be horizontally positioned according to the standard line copy provided, and the embedded spacing shall be installed according to the site size and drawing design requirements.

(4) The installation deviation must meet the national regulations and design requirements, and meet the acceptance standards.

(5) Embedded parts, iron guardrail installation b must be firm, installation deviation according to national regulations and design requirements: straightness <3mm, verticality <3mm, railing spacing error <3mm, diagonal error <3mm, embedded parts vertical error <3mm, horizontal error <3mm.

(6) The installation and positioning of the embedded parts are accurate and accurate. After receiving, brush two anti-rust paints, and then install the iron railing.
