Description
Technical field
The present invention relates to a kind of card cable device, particularly relate to the compressible U-shaped steel card cable of a kind of comprehensive high strength used for mine laneway.
Background technology
U-shaped steel bracket refers to and is interconnected each other by metal connecting piece by U-shaped steel section, forms half (entirely) closed metal support with cross-section shape of roadway.Card cable is the one of U-shaped steel bracket metal connecting piece, because its structure is simple, convenient and practical, moderate and by extensive practicality.
At present, in roadway and the U-shaped steel bracket supporting construction of geotechnical engineering, be by after U-shaped steel section head and the tail superposition between two overlap joint, then fix with U-shaped steel metal connecting device.The method is strong adaptability in well lane engineering, but metal connecting device no matter strength and stiffness, or profile, all will through special processing, and cost is relatively high.And, metal connecting device is contacted abundant not with first by admittedly U-shaped steel, Stationary liquid is to firm not, only can be limited to and shrink at the U-shaped steel above-below direction of two joints, and left and right directions is rigidly connected, if when tunnel horizontal pressure force is large, pressure is allowed due to finite deformation can not be realized in the lateral direction, U-shaped steel metallic support superposition coupling part in the lateral direction, is easily distorted and fractures, causing bracket support to lose effect.Like this, tunnel just faces the danger of reprocessing or scrapping, and wastes human and material resources and financial resources greatly.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the compressible U-shaped steel card cable of a kind of structure comprehensive high strength simple, esy to use, safe and reliable.
The technical scheme that the present invention solves the problem is: comprise the first U-shaped bloom, the second U-shaped bloom, first by admittedly U-shaped steel, second by admittedly U-shaped steel, compressible annular sleeve and bolt; Described first U-shaped bloom, the second U-shaped bloom bottom surface all have bolt hole, first is had rectangular opening by admittedly U-shaped steel and second by corresponding on the bottom surface of admittedly U-shaped steel junction, described first by admittedly U-shaped steel or/and second is provided with two springs by admittedly U-shaped steel or second by the axis direction of admittedly U-shaped steel along first by the rectangular opening place of admittedly U-shaped steel, one end of two springs is arranged near the two ends of rectangular opening respectively, and the other end of two springs is all towards rectangular opening center; Described first U-shaped bloom and the second U-shaped bloom clamping first by admittedly U-shaped steel and second by admittedly U-shaped steel junction, the first U-shaped bloom, the second U-shaped bloom, first by admittedly U-shaped steel with second by the opening of admittedly U-shaped steel towards consistent; Described compressible annular sleeve is placed in the first U-shaped bloom and first by admittedly U-shaped steel or second by between admittedly U-shaped steel; Bolt by the first U-shaped bloom, the second U-shaped bloom, first by admittedly U-shaped steel, second by admittedly U-shaped steel and compressible annular sleeve fastening.
In the compressible U-shaped steel card cable of above-mentioned comprehensive high strength, the strength and stiffness of described bolt are greater than the first U-shaped bloom, the second U-shaped bloom, first by admittedly U-shaped steel and second by the strength and stiffness of admittedly U-shaped steel.
In the compressible U-shaped steel card cable of above-mentioned comprehensive high strength, described compressible annular sleeve is the spherical of hollow.
Compared with prior art, the invention has the beneficial effects as follows: the first U-shaped bloom of the present invention and first is provided with compressible annular sleeve by admittedly U-shaped steel or second by between admittedly U-shaped steel, compressible annular sleeve has along parallel bolt shaft to compressibility, the present invention is had along parallel bolt shaft to compressibility, realizes the compressible of U-shaped steel bracket left and right directions.
Described first is had rectangular opening by admittedly U-shaped steel and second by admittedly U-shaped steel bottom surface, first by admittedly U-shaped steel or/and second is welded with spring respectively by near admittedly U-shaped steel rectangular opening two ends, the present invention can be stretched by admittedly U-shaped steel axis direction along first, realize the compressible of U-shaped steel bracket above-below direction.
Therefore, the present invention, in the simple situation of structure, achieves the comprehensive compressibility of U-shaped steel bracket above-below direction and left and right directions, has good supporting effect, and can adapt to the large deformation feature of heavily stressed loose weak country rock, safety is high.And waste and old U-shaped steel section is more in Mineral Engineering, the present invention can make full use of these waste and old U-shaped steel sections, after simple and easy perforate, gets final product practical application, reduces manufacturing cost.
