The inner layer body and the outer layer thread structure layer are made of inorganic nonmetal fiber materials, so that the environment-friendly property and the renewable utilization property are good; meanwhile, the product has high strength, high temperature resistance, good durability, corrosion resistance (acid and alkali resistance), no water absorption and good dielectric property.
Description
Technical Field
The utility model relates to the field of new material application, in particular to a composite water stop screw.
Background
Fiber Reinforced composite (FRP) is a composite formed by winding, molding or pultrusion a reinforcing Fiber material, such as glass Fiber, carbon Fiber, aramid Fiber, etc., with a matrix material. Common fiber-reinforced composites are classified into glass fiber reinforced composites (GFRP), carbon fiber reinforced Composites (CFRP), and aramid fiber reinforced composites (AFRP) according to the reinforcing material.
The fiber reinforced composite material has the characteristics that (1) the specific strength is high, and the specific modulus is large; (2) the material performance is designable; (3) the corrosion resistance and the durability are good; (4) the coefficient of thermal expansion is similar to that of concrete. The characteristics enable the FRP material to meet the requirements of modern structures on large span, high rise, heavy load, light weight, high strength and work development under severe conditions, and can also meet the requirements of industrialized development of modern building construction, so that the FRP material is more and more widely applied to the fields of various civil buildings, bridges, highways, oceans, hydraulic structures, underground structures and the like.
In modern building construction, the stagnant water screw rod is a commonly used product, and the stagnant water screw rod in the existing market is mainly still iron material, and iron material has corrosion and difficult cutting scheduling problem after using, for this reason the building is pouring the completion back, and the processing to the stagnant water screw rod is the thing that consumes manpower, material resources relatively.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model provides the composite material water stop screw which is more convenient to cut in use, better in corrosion resistance and more stable than the traditional iron water stop screw.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a combined material stagnant water screw rod, includes inlayer body and outer layer thread structure layer, the body is full radial fibre yarn, be provided with the screw thread on the outer layer thread structure layer.
In the above technical solution, preferably, the inner layer body is integrally formed. No subsequent processing is needed, and the consistency and the stability of the product performance are ensured.
In the above technical scheme, preferably, the outer thread structure layer is a one-step forming structure. No subsequent processing is needed, and the consistency and the stability of the product performance are ensured.
In the above technical scheme, preferably, the inner layer body and the outer layer thread structure layer are made of inorganic non-metallic fiber materials. Has good environmental friendliness and reproducibility; meanwhile, the product has high strength, high temperature resistance, good durability, corrosion resistance (acid and alkali resistance), no water absorption and good dielectric property.
In the above technical solution, preferably, the inorganic nonmetallic fiber material is one of glass fiber, basalt fiber, and aramid fiber, or a fabric of one of them.
Among the above-mentioned technical scheme, preferred, outer layer thread structure layer arranges full thread sand grip. The friction force on the surface of the product can be increased by the arrangement, so that the product has a wider range in engineering application.
In the above technical solution, preferably, the inorganic nonmetallic fiber materials in the inner layer body are radially arranged.
In the above technical solution, preferably, the inorganic nonmetallic fiber material in the outer thread structure layer is axially wound and arranged.
Through the setting for combined material stagnant water screw rod has higher tensile strength than iron stagnant water screw rod, and outer layer thread structure layer provides the screw thread shape of also nut connecting piece, just enables this product through simple mechanical connection and is applied to various occasions.
The utility model has the beneficial effects that:
1. the product has better strength, saves processing procedures and reduces production cost.
2. The inner layer body and the outer layer thread structure layer are made of inorganic nonmetal fiber materials, and have good environmental friendliness and recyclability.
