Problems solved by technology
The simple construction method, also known as the prestressed anchor construction and installation method, belongs to the construction and installation of small anchors. It is a simple construction and simple construction that drills a cylinder with a diameter of 28-75 mm and a depth of 1-Sm in the rock that is installed by the anchor. It can be drilled or manually drilled, and then explosives are charged in a simple construction method. The simple construction method can be used for excavating foundation pits, mining stones, loosening frozen soil, etc., but the amount of installation of anchors is small, the efficiency is low, and the drilling workload is low. Big

The invention discloses a pre-stressed anchorage device. The pre-stressed anchorage device comprises high-strength fiber cloth, two anchor heads, at least two screw rods and nuts, wherein the high-strength fiber cloth is arranged on the surface of a to-be-reinforced component in a surrounding way; the two anchor heads are arranged in parallel, and a gap is reserved between the two anchor heads; two end parts of the high-strength fiber cloth are connected with the anchor heads; the at least two screw rods are at least connected with the end parts of the two anchor heads; the nuts and the screw rods are in meshing installation. The invention also discloses a production method of the pre-stressed anchorage device. According to the pre-stressed anchorage device disclosed by the invention, the practicability is high, an application process of a pre-stress force is controllable and easy, and enough safety stock is obtained while the strength and the higher utilization rate of materials are ensured.
Description
technical field [0001] The invention belongs to the technical field of prestressed parts, and specifically refers to a prestressed anchor and a production method thereof. Background technique [0002] Prestressed anchor refers to the permanent anchoring device used in prestressed concrete. It is an anchoring tool used in post-tensioned structures or components to maintain the tension of prestressed tendons and transfer them to the interior of the concrete. [0003] Anchors can be divided into two categories according to the type of use: (a): Anchor tools that are installed at the end of the prestressed tendon and can always keep the prestressed tendon in an anchored state during the tensioning process of the prestressed tendon. Tension end anchors can be divided into different types of anchorage: clip anchors (YJM) for tensioning prestressed steel strands, steel tapered anchors (GZM) for tensioning high-strength steel wires, Pier head anchors (DM) used for tensioning high-s...
