Embodiment Construction
[0009] A glass fiber reinforced plastic U-shaped bolt and its manufacturing method are characterized in that the glass fiber reinforced plastic U-shaped bolt is composed of three parts: one end is threaded and the other end is made of two screw rods 1 with external splayed heads; The U-shaped curved rods 2 of the parallel outer splayed heads, the outer splayed heads of the screw rod 1 and the U-shaped curved rod 2 are butted and fixed with each other;
[0010] The method of making FRP U-shaped bolts is to use imported epoxy resin and glass fiber products as raw materials; use conventional technology to make plates, and then process them into screw rods 1, one end of which is threaded, and the other end has an outer splayed head, both of which can be used equally It is connected with the round platform transitional on the outer diameter of the screw; the U-shaped curved rod 2 is formed by molding, including a semicircle and the ends are parallel to each other, and each has an ou...

The invention relates to a glass-steel U-shaped bolt and a manufacturing method thereof. The glass-steel U-shaped bolt comprises a screw rod, a U-shaped bent rod and a reinforced connecting piece, wherein the end parts of the screw rod are respectively provided with a thread and an out-toe head; the U-shaped bent rod is semicircular and provided with an out-toe head at the end part, wherein the out-toe head is butted with the out-toe head of the screw rod; and the reinforced connecting piece is fixed outside at a butting part between the out-toe head of the U-shaped bent rod and the out-toe head of the screw rod. The manufacturing method comprises the following steps of: by taking epoxy resin and glass fiber products as raw materials, firstly making into a plate, and then machining into the screw rod; machining into the U-shaped bent rod by a die pressing way, and mutually butting and bonding the out-toe heads; and winding the butting part and manually machining into the reinforced connecting piece. Compared with stainless steel, the invention has the tensile strength of 1 / 4 to 1 / 3, the weight of 1 / 3, and the weather resistance of about 20 years, thereby saving non-ferrous metals,especially solving the problems of corrosion and electric insulation in the prior art and being capable of being widely applied in the fields of electric powers, municipal administration, building, chemical engineering, medicines, pesticides, metallurgy, environmental protection, and the like.
Description
technical field [0001] The present invention belongs to the subcategory of fastening or fixing components in the International Patent Classification, that is, F16B, and particularly relates to corrosion-resistant bolts and screws. Background technique [0002] The U-shaped bolts made of steel and iron materials adopt the bending and stamping process of threaded screw rods. It has high tensile strength but is not corrosion resistant. Stainless steel U-bolts are manufactured by the same process. They also have the advantages of high strength and corrosion resistance, but they are also not suitable for occasions requiring electrical insulation. The applicant is one of the earliest enterprises in China to develop FRP products. The "FRP" mentioned here is widely known to the public, and it is called "glass fiber reinforced plastic" abroad, but only a few professionals know it. Since many domestic industries urgently need corrosion-resistant or even electrically insulating pipes...
