Abstract
本发明属于土木工程技术领域，具体涉及一种形状记忆合金锚固体系，由形状记忆合金筋，套筒和夹片组成，其特征在于形状记忆合金筋两端为倒锥台体，中部为圆柱体，套筒一侧开孔，形状记忆合金筋端部穿入套筒的开孔部位，形状记忆合金筋端部与套筒内部连接处设有夹片。与传统的锚固方法不同，该体系利用挤压力进行锚固，从而避免了因形状记忆合金的硬度过大而无法利用摩擦力或粘结力进行锚固，而且工艺简单，生产成本低，在土木工程领域具有较广阔的应用前景。
The invention belongs to the technical field of civil engineering, and specifically relates to a shape-memory alloy anchoring system, which is composed of a shape-memory alloy tendon, a sleeve and a clip, and is characterized in that both ends of the shape-memory alloy tendon are inverted cones, and the middle part is a cylinder A hole is opened on one side of the sleeve, the end of the shape memory alloy rib penetrates into the opening of the sleeve, and a clip is provided at the connection between the end of the shape memory alloy rib and the inside of the sleeve. Different from the traditional anchoring method, this system uses extrusion force for anchoring, thus avoiding the failure of friction or cohesive anchoring due to the excessive hardness of the shape memory alloy, and the process is simple and the production cost is low. It is widely used in civil engineering The field has broad application prospects.
Description
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.
