How to use chemical bolts, chemical bolt installation methods

How to use chemical bolts:

1. Drilling: According to the design requirements, the position is determined according to the spacing and margin of the drawings, and the hole diameter and depth must meet the design requirements.

2. Hole cleaning: Use air pressure blowpipe and other tools to remove the floating ash and dust in the hole to keep the hole clean.

3. Insert the medicine tube: Insert the medicine tube into a clean hole, and use the hose only when the resin can flow like honey under hand temperature when inserted.

4. Drill into the bolt: use an electric drill.

Screw in the screw until the agent flows out. Electric drills generally use percussion drills.

or hand drills with a penetration rate of 750 rpm. At this time, the bolt is screwed in, and the agent tube will be broken, resin, and curing agent.

and quartz grains and fill the gap between the anchor bolt and the hole wall.

At the same time, the anchor bolt can also be inserted into the wet hole, but the water must be drained out of the borehole, and the waiting time for the gelling process and the hardening process must be doubled.

5. Gel process: keep the installation tool still and the chemical reaction.

See details for timing.

6. Hardening process: remove the installation tools and wait for the agent to harden, and the chemical reaction time is shown in details.

7. Fix the object: After the agent is completely hardened, add a washer and a hexagon nut to fix the object.

Chemical bolts are composed of chemical hoses, screws, washers and nuts. Screws, washers, nuts (hexagons) are generally galvanized steel and stainless steel (hot-dip galvanized can also be required as required.

Chemical hoses (or plastic-wrapped pharmaceutical tubes) contain reactive resins, hardeners, and quartz particles.

Specific use of chemical anchors:

1. According to the requirements of engineering design, drill holes in the corresponding position in the base material (such as concrete), and the hole diameter, hole depth and bolt diameter should be drilled by professional and technical personnel.

2. Use a special air cylinder, brush or compressed air machine to clean the dust in the borehole.

3. Ensure that the surface of the bolt is clean, dry and oil-free.

4. Confirm that there is no abnormal phenomenon such as appearance damage and coagulation of the glass tube anchor package.

5. Use an electric drill and a special installation fixture to rotate the screw and insert it until the bottom of the hole.

6. When it is screwed to the bottom of the hole or the marked position on the bolt, stop rotating, remove the fixture, and avoid disturbance after gelling until it is completely cured.

Chemical anchor bolt is a high-strength anchor bolt with vinyl resin as the main raw material, which was called chemical bolt in the early days. Chemical anchor bolt is a new type of anchor bolt that appears after the expansion anchor, which is a composite part that is cemented and fixed in the concrete substrate borehole through a special chemical adhesive to realize the anchorage of the fixing.

How should chemical bolts be used, the guy fixes the bolts on the wall, and the tensile force is no worse than ordinary expansion.

The standard construction process for HAMM chemical bolts is as follows:

1. Substrate drilling: drilling tools - impact electric hammer;

2. Hole clearing: 1Use compressed gas such as an air pump or gas cylinder to blow away the dust in the hole;

2.Use a brush to remove the dust attached to the inner wall of the hole;

3.Step gathering is repeated many times to remove the dust in the hole to the greatest extent;

3. Put the medicine tube: Confirm the fluidity of the resin by hand or visual inspection, and then insert the agent into the bottom of the hole after confirmation;

4. Screw-in screw: the screw is embedded in the front end with a 45° chamfering angle, and the rear end is screwed into the hexagonal nut and driven by an electric tool to screw into the bottom of the hole to stop, and confirm that there is resin rising to the vicinity of the orifice;

6. Fixed objects: objects can be fixed after the curing period;

7. Storage: Store in a cool and dry place away from light, and the storage period is 12 months.

The installation method of the chemical spiral is as follows: 1. Drilling: First of all, according to the design requirements, determine the position according to the spacing and margin of the drawing, and drill the hole on the foundation.

The hole diameter and depth of the hole must meet the design requirements. 2. Hand wash the holes: use air pressure blowpipes and other tools to remove the dust and dust in the holes and keep the holes clean.

3. Insert the medicine tube: Insert the medicine tube into a clean hole, and use the hose only when the resin can flow like honey at hand temperature. 4. Drilling bolts:

Tighten the screw with an electric drill until the agent flows out. Electric drills usually use percussion drills or hand drills with a speed of 750 rpm. After the screw is tightened, the tube breaks, the resin, curing agent, and quartz particles are mixed, and the gap between the screw and the hole wall is filled.

It is also possible to insert anchor bolts into wet holes, but water must be pumped out of the holes and the waiting time for the gel hardening process must be doubled. 5. Gel method: keep the installation tool still.

See chemical reaction time for details. 6. Hardening process: remove the installation tool and wait for the medium to harden.

See chemical reaction time for details. 7. Fixing the object: After the agent is completely hardened, fix the object with a washer and a hexagonal nut.

Chemical bolts consist of chemical hoses, screws, washers, and nuts. Screws, washers, nuts (hexagonal heads) are generally galvanized steel and stainless steel (hot-dip galvanized can also be upon request). This chemical hose (or plastic-encased chemical hose) contains reactive resins, hardeners, and quartz particles.
