Abstract

The invention belongs to the technical field of civil engineering and particularly relates to a shape memory alloy anchoring system, which consists of a shape memory alloy, a sleeve and a clamping piece, and is characterized in that: the two ends of the shape memory alloy are an inverted frustum bodies; the middle part of the shape memory alloy is a cylinder body; one side of the cylinder has an opening; the end part of the shape memory alloy is inserted into the hole of the sleeve; and the clamping piece is arranged at the connection part of the end part of the shape memory alloy and the inside of the sleeve. Different from the conventional anchoring method, the system uses extrusion force for anchoring and thereby solves the problem that the shape memory alloy cannot be anchored by a friction force or adhesive force due to overhigh hardness; and the system has a simple process, can be produced at low cost and has a promising application prospect in field of civil engineering.

Description

A kind of marmem anchoring system
Technical field
The invention belongs to technical field of civil engineering, be specifically related to a kind of marmem anchoring system.
Background technology
Along with going deep into of civil engineering research, the research of intelligent civil engineering and application are subjected to increasing attention.Intellectual materials such as marmem are connected structurally after designing, can greatly improve the safety and the reliability of structure, avoid the generation of disastrous accident.Marmem is a kind of important intellectual material, compares with traditional civil engineering material, and it has self-sensing properties and shape memory effect.In the existing research, marmem is embedded in the concrete component mostly, realizes being connected of marmem and other materials by utilizing frictional force or adhesion stress.This method of attachment has determined marmem to be applied in the new building, and driving force can not can't be brought into play the big characteristics of marmem driving force above friction or the anchored force that bonds and provided.The inventor patent " intelligent prestress system " (patent No.: 200510028189.6) with marmem with the arranged in form of external prestressing muscle outside structure, pier nose formula ground tackle and agent structure anchoring are adopted in two ends.This connected mode can avoid the marmem temperature to raise to the adverse effect of the normal functional performance of agent structure, and the range of application of marmem widened to existed building from new building, but the driving force that produces can only reach about 80% of maximum driving force, still can't give full play to the big characteristics of marmem driving force.As seen, anchorage style is to hinder the technical problem underlying that marmem is applied in intelligent civil engineering, develops the urgent problem that the effective anchor device of a cover has become the marmem intelligence structure.
Summary of the invention
The object of the present invention is to provide a kind of marmem anchoring system, the present invention has realized that the marmem muscle is connected with the effective of other materials, has advantages such as technology is simple, cost of production is low.
The marmem anchoring system that the present invention proposes, by marmem muscle 1, sleeve 2 and intermediate plate 3 are formed, wherein: marmem muscle 1 two ends are the back taper stage body, the middle part is a cylinder, sleeve one STH, marmem muscle 1 end penetrates the perforate position of sleeve 2, and marmem muscle 1 end and sleeve 2 internal connections are provided with intermediate plate 3.
Among the present invention, the size of described intermediate plate 3 medial surfaces and marmem muscle 1 end lateral surface is complementary.
Among the present invention, described intermediate plate 3 lateral surfaces are semicircle; Medial surface is half truncated cone-shaped, and is measure-alike with marmem muscle 1 end lateral surface.
Among the present invention, utilize the extruding force of marmem to carry out anchoring, avoided utilizing in traditional anchoring process frictional force or adhesion stress to carry out anchoring.(this sentence repeats with following the meaning, could delete?)
Marmem anchoring process provided by the invention is different with conventional method, this system utilizes extruding force to carry out anchoring, thereby avoided to utilize frictional force or adhesion stress to carry out anchoring because of the hardness of marmem is excessive, and technology is simple, cost of production is low, has more wide application prospect in field of civil engineering.

The specific embodiment
Further specify the present invention below in conjunction with accompanying drawing.
Embodiment 1: as Fig. 1-shown in Figure 7, marmem anchoring system of the present invention comprises: marmem muscle 1, sleeve 2 and intermediate plate 3.The back taper stage body is processed at the two ends of marmem muscle 1.At first marmem muscle 1 is penetrated sleeve 2, then intermediate plate 3 is put into sleeve 2, the two ends of sleeve 2 to marmem muscle 1 are stretched, marmem muscle 1, sleeve 2, intermediate plate 3 are combined closely, form an integral body.Be connected with other materials by the screw thread on the sleeve 2.
