High quality fastener is a kind of mechanical part which is widely used for fastening connection. It is widely used in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments and supplies. It is the most widely used mechanical foundation.
It is characterized by a wide variety of specifications, different performance uses, and standardization, seriation, generalization of the degree is also very high. Therefore, some people call the fastener of a kind of national standard as standard fastener, or simply as standard fastener.
Chemical anchor bolt is a new type of fastening material, which is composed of chemical reagent and metal rod It can be used for installation of post embedded parts in various curtain walls and marble dry hanging construction It can also be used for equipment installation, road and bridge guardrail installation, building reinforcement and other occasions Because the chemical reagent contained in the material glass tube is inflammable and explosive, the manufacturer must obtain the approval of the relevant national departments before production Strict safety measures are required in the whole production process, and the production line completely isolated from the staff must be used If it is done by hand, it not only violates the relevant regulations of the state, but also is very dangerous.
Chemical bolt is a new type of bolt after expansion bolt The special cement bond is used to fix the screw cement in the hole of the crucible base to realize the composite component fixed on the fixing device.Products are widely used for fixing curtain wall structure, installation machinery, steel structure, railings, windows, etc.
1. According to the engineering design requirements, drill holes at corresponding positions of baseplate (such as concrete), and the hole diameter, hole depth and bolt diameter shall be determined by professional technicians or field tests.
2. Drill with a percussion or water drill.
3. Use a special air pump, brush or compressed air machine to clean the dust in the borehole It is recommended to repeat at least 3 times There should be no dust or water in the hole.
4. Make sure the bolt surface is clean, dry and free of oil.
5. Confirm that the glass tube anchor bag is normal, such as appearance damage and drug solidification, put the round head into the anchor hole and push it to the bottom of the hole.
6. Use electric drill and special installation fixture to screw the screw into the hole bottom, with strong rotation The impact method should not be used.
7. When the position is screwed to the bottom of the hole or bolt, stop rotating immediately, remove the mounting fixture and avoid interference before the gel is completely solidified. Excessive rotation causes the glue to drain and affects the anchoring force.
