Chemical bolt

Chemical bolts rely on both the interlocking force with concrete and mechanical bonding forces to resist pull-out forces, while the bolts themselves provide shear resistance. They are primarily used at the joints between old and new structures. For information on their mechanical properties, one can refer to the product descriptions provided by the manufacturers; calculations should be carried out based on the data supplied by these manufacturers. Since chemical adhesives produced by different manufacturers vary, their bonding capacities also differ. Some well-known brands from outside mainland China that produce chemical bolts include Schilte from Germany, Huiyu Anchors from Germany, and Gutyou from Taiwan； There are many brands on the mainland, and their quality varies; it is necessary to carefully verify their performance before using them. Chemical bolts are a type of post-installed component, used when embedded components are missed or in projects constructed later.

Properties of chemical bolts: resistant to acids and alkalis, low temperatures, and aging; good heat resistance with no creep at normal temperatures; resistant to water damage, maintaining stability under long-term exposure in humid environments; good weld resistance and flame-retardant properties; excellent seismic performance.

Advantages of chemical bolts: Strong anchoring force, acting as if they are embedded; no expansion stress, allowing for small spacing between components. Fast installation, rapid curing, which saves construction time. The glass tube packaging facilitates visual inspection of the quality of the adhesive. Once crushed, the glass tubes can be used as fine aggregate, ensuring good adhesion.

Applications of chemical bolts: Suitable for fixing heavy loads at short distances and on narrow components such as columns and balconies. Can be used in concrete (>=C25 grade). Can also be used for anchoring in pressure-resistant natural stones (without prior testing). Applicable to fixing rebar, metal components, tie rods, machine bases, road barriers, formwork, the base of soundproof walls, road signs, sleepers, floor edges, heavy support beams, roof decorative elements, windows, protective nets, heavy elevators, floor supports, construction scaffolding, transmission systems, sleepers, support and shelf systems, crash prevention devices, car trailers, pillars, chimneys, heavy signage, heavy soundproof walls, heavy doors, complete sets of equipment, tower cranes, pipeline installations, heavy trailers, guide rails, connection of plates, heavy partitioning systems, shelves, and fixation of sunshades.

Stainless steel A4 bolts can be used in outdoor areas, humid environments, industrial polluted areas, and coastal regions. Galvanized steel and stainless steel A4 are not suitable for humid environments containing chlorine, such as indoor swimming pools. Suitable for fixing substrates with small spacing requirements and multiple anchor points. Last edited by Tjuleo on 2009-4-14 15:10
