Background technology
Usually steel support brace pre axial force adopts active head to be used with jack, promptly locates to load axle power to preset value by jack at active head, more active head is fixed.There is following some shortcomings part in this form: the one, and when steel was supported on brace pre axial force, jack was arranged at the both sides that steel supports, and steel supports eccentric compression during loading, causes supporting member to be easy to the both sides discontinuity; The 2nd, after jack loads, use gad that active head fix, when gad deforms or during slippage, can cause the off-load of steel support; The 3rd, jack can only support steel and add unidirectional axial compression in advance, can't apply axial tension; The 4th, because of jack dismounting inconvenience, after the steel supporting loading, again its axial force is adjusted very difficult; The 5th, when removing the steel support, steel supports suffered load meeting moment removal, easily produces potential safety hazard.
Summary of the invention
The purpose of this invention is to provide a kind of adjustable steel and support brace pre axial force device and using method thereof, solve traditional steel and support the technical problem of using inconvenience, steel support brace pre axial force to regulate.
For achieving the above object, the present invention adopts following technical scheme: a kind of adjustable steel supports the brace pre axial force device, it is characterized in that: by axis, be connected the left pedestal of axis left end, the right pedestal that is connected the axis right-hand member is formed with the release handle that is connected the axis middle part, the structure of wherein left pedestal and right pedestal is identical, by sleeve, be welded to connect at the supporting plate of sleeve one end and the stiffener that is connected between sleeve lateral wall and the supporting plate and form, described supporting plate is by bolt and steel support and connection, described jacket casing is connected with axis on axis and by screw thread, and left pedestal is opposite with the hand of spiral between the axis with right pedestal with the screw thread between the axis.
Described axis can be hollow shaft or solid shafting.
Described screw thread can be trapezoidal thread, rectangular thread or saw-tooth thread.
Described release handle can be along be radially distributed with four of axis.
Described stiffener can be radially distributed with four along sleeve.
A kind of adjustable steel supports the using method of brace pre axial force device, it is characterized in that: left pedestal, right pedestal and the axis that adjustable steel is supported in the brace pre axial force device fits together earlier, with bolt left pedestal, right pedestal and steel are supported connection then, pass through the release handle rotating middle shaft at last, give steel supporting loading axle power.
Compared with prior art the present invention has following characteristics and beneficial effect: the present invention is that a kind of foundation ditch steel that is applicable to supports the adjustable augmentor of brace pre axial force, have simple in structure, peace is torn convenience, flexible operation safety open, can adjust the advantage of the axle power of steel support at any time.The present invention can accurately control the steel axial force of the supports, so increased the safety of foundation ditch support system, simultaneously easily simplified control complicated work progress, accelerated construction speed, reduced engineering cost, the flange bolted on connection that supporting plate among the present invention and steel support is an one, become the part that steel supports, can support the two-way axle power that provides to steel by threaded adjusting, and guarantee to provide the axle center pre-applied force to support, especially can support in the use at steel, the increase and decrease of its power is finely tuned.
The present invention also has following 4 characteristics, and the one, be arranged on the axis of steel support, support uniaxial force during loading, the supporting member both sides are stressed evenly; The 2nd, adopt the trapezoidal thread loading principle, need not gad and reinforce, the off-load that can not cause steel to support; The 3rd, a two-way power that applies can provide axial compression, also can provide axial tension; The 4th, conveniently its power is adjusted, when removing the steel support, can realize slow unloading.
Description of drawings
The present invention will be further described in detail below in conjunction with accompanying drawing.
