Description

Complete equipment for producing glass fiber rib joints by wire rope pultrusion

Technical field

The invention belongs to the field of thermal insulation wall connecting parts, and particularly relates to a complete set of equipment for producing glass fiber rib joints by pultrusion winding of steel wire ropes.

Background technique

Precast concrete sandwich insulation wall is a new type of prefabricated thermal insulation wall integrating load bearing and heat preservation. The wall consists of inner and outer concrete wall panels, intermediate insulation layer and connecting parts. The connecting piece is connected with concrete sandwich insulation wall. The key components of the outer concrete wall panel and the intermediate insulation layer are mainly used to resist the interlaminar shear between the two concrete wall panels. According to different materials, the connecting parts are mainly divided into three types: ordinary steel connecting parts, metal alloy connecting parts and glass fiber composite connecting parts.

Glass fiber reinforced plastic is a glass fiber reinforced composite material which is easy to cut and is thermally fused by glass fiber and resin. The main function of the resin matrix material is to bond the fiber bundles together and make them have a fixed shape and It transmits the shearing force and protects the fibers from the physical and chemical corrosion of the surrounding environment, so that the glass fiber ribs have high corrosion resistance. At the same time, the density of the glass fiber ribs is about one quarter of that of the steel bars. Under the same diameter, the quality of the glass fiber ribs is much lower than that of the steel bars, which is beneficial to the production and transportation of the glass fiber ribs, and the glass fiber ribs are obtained according to experiments. The tensile strength is higher than that of ordinary steel bars, which is suitable for the dangerous pit with large tonnage protection. Therefore, a complete set of equipment for producing glass fiber rib joints has been greatly welcomed by the market.

The process is complicated and complicated, it can not be formed at one time, it takes time and labor, and the on-site processing is difficult, and the cost is extremely high, which is not conducive to mass production of commercial production. At present, when producing the outer surface thread of the glass fiber rib joint, the production equipment is wound with polyester thread. Each thread is wound by a polyester thread. After the molding is cured, manual stitching is required. After use, the polyester thread cannot be used repeatedly, resulting in waste of the polyester thread. Due to the tightness of the polyester thread, the produced fiberglass rib connection is produced. Pieces have low tensile properties and often require more resin with good performance, increase the cost of raw materials, and require manual disconnection, increasing labor costs while reducing production efficiency.
