What are the preparations before the construction and installation of seismic support?

Preparation before construction and installation

Preparation before installation

According to the market, at present, most domestic installation enterprises have no experience in the installation of anti-seismic supports and hangers or have too little experience in installation. Problems occur frequently in the formal installation and construction process, which seriously affects the construction quality and project progress.

Therefore, the manufacturer of seismic supports and hangers shall be responsible for the installation technical guidance on site, and the installation unit shall prepare the installation scheme and conduct pre job training for personnel before the installation of seismic supports and hangers.

Seismic support and hanger construction materials

It mainly includes anchors, reinforced suspenders, anti-seismic connecting members, pipeline connecting members, anti-seismic diagonal bracing, section steel and fasteners; Note: all components constituting seismic supports and hangers shall be finished components; Because the seismic supports and hangers are concentrated in the basement, which belongs to indoor humid environment, the materials of seismic supports and hangers are generally hot-dip galvanized.

The installation of seismic supports and hangers shall be carried out after the installation of load-bearing supports and hangers. When rooting in the concrete structure, the holes shall be drilled first, and the completed holes shall be cleaned before the installation of anchor bolts. The anchor bolts shall be rear expanding anchor bolts; Rooting on steel columns and beams shall be connected with special beam clamps.

Construction preparation

1. Be familiar with construction drawings. Before construction, first understand the detailed drawings and recheck the calculation sheet and checking sheet. Find out the situation of the project, review the project quantities, compare the detailed drawings of each node, and prepare the corresponding installation scheme in advance for places with great construction difficulties.

2. Prepare documents. Prepare a reasonable construction scheme according to the drawings and the actual situation of on-site pipeline installation.

3. Material preparation. Prepare the required materials, components and accessories according to the quantities of drawings, and negotiate with the receiving unit on the mobilization time node, mobilization route and storage location of goods in combination with the overall progress of the project.

4. Technical disclosure. After the materials are mobilized and accepted, the team shall be organized to conduct on-site investigation in time, and the technical disclosure shall be made to the team leader. The principle of sample first shall be adhered to and the installation of sample shall be carried out.

Preparation is an important prerequisite for carrying out a project and the locomotive ahead. Only by making preliminary preparations can we ensure the smooth progress of follow-up work.
