Junction plate of the present invention, fixed head, anchor base plate, anchoring ribbed panel, anchor connection plate, anchor plate, front plate, rear plate, middle clamp plate, web ribbed panel, shrouding, preceding junction plate, back fishplate bar, front shoe, rear fixed plate all are to be processed by steel plate.Front tension bar, back stay are fining twisted steels.Capped pipe, column, forward press, back depression bar are that spiral welded pipe processes.Anchor nut, anchor plate are the fining twisted steel auxiliary products.Wheel shaft, short wheel shaft are to be processed by the rod iron weaving done in fine silks and gold thread by the tapestry method.Lining, short lining are to be processed by high-abrasive material.Connecting rod, bracing piece, H shape connector are to be processed by shaped steel.It is to be formed by cast steel moulding reprocessing that cylinder, round platform roll.Power transmission of the present invention and reach mode are as follows; Other masterpiece times spent such as the concrete of being poured into a mould when the front plate branch, template, power is decomposed into pulling force and pressure by front plate.This pulling force is passed to front tension bar, and pressure is passed to forward press.Front tension bar is passed to capped pipe with power, and capped pipe is decomposed into pulling force and pressure again with power.Pulling force is passed to back stay, and pressure is passed to column.Back stay is passed to rear plate with power, and rear plate is decomposed into power once more: vertical force and horizontal pressure force.Vertical vertical force passes to anchor part behind the Hanging Basket, behind the Hanging Basket anchor not in this equipment with beam in the smart rib steel balance of pricking.Horizontal pressure force is passed to the back depression bar, and back depression bar is passed to middle clamp plate.Column is passed to middle clamp plate with pressure, and middle clamp plate is passed to cylinder through connecting rod, junction plate, front shoe, wheel shaft, and cylinder is passed to the track that places on the beam face.Forward press is passed to middle clamp plate with pressure, balances each other with the pressure of back depression bar transmission.This steel tube concrete tripod, the transmission of power has formed closed triangle, reaches stable force structure.
When the construction of the various operations of a section concrete finishes, the Hanging Basket template is loosening, and this moment, this equipment no longer bore concrete gravity, had only template weight.The transmission of power and above-mentioned have only with, the vertical force that rear plate decomposes no longer pass to behind the Hanging Basket behind the anchor Hanging Basket anchor not in this equipment scope, but pass to the round platform cylinder by connecting rod, junction plate, rear fixed plate, minor axis.The round platform cylinder colludes in track and under two frange plates, power is not passed in track in this equipment scope.Cylinder rolls in rail top face when Hanging Basket moves forward, and round platform rolls under the track frange plate and rolls, and has realized the reach of rolling.
Transmission by above-mentioned power is known: front tension bar, back stay rod member bear pulling force.Known: carry outside after pulling force determines, required rod member cross-sectional area is inversely proportional to bar material permission tensile stress intensity, and promptly bar material allowable tensile stress intensity is big more, and then required cross-sectional area is more little.It is 6-7 times of common shaped steel that high tensile reinforcement allows tensile stress intensity, so adopt high tensile reinforcement to reach the weight reduction of saving steel.
Transmission by above-mentioned power is also known: column, forward press, back depression bar are compression member, known concrete is the pressurized ideal material, the pressurized concrete is subjected to the constraint of steel pipe walls in steel pipe again, the pipe inner concrete is in the three dimension stress state, bearing capacity can be brought up to 1.7 times, replace the common iron pressurized with concrete filled steel tube, saved material in a large number.
