The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
The present embodiment be take Novel power transmission shaft tower as example, as shown in Figures 1 to 5, the Novel power transmission shaft tower that the embodiment of the present invention provides comprises: tower body 1, supervisor 2, honeycomb structure 3, filler 4, reinforced concrete foundation 5, cement 6, flange 7, cross-arm 8, connected node 9, earth wire support 10, junction plate 11, stiffener 12, connecting screw hole 13.The honeycomb structure 3 consisting of around a hollow regular hexagon body six hollow regular hexagon bodies is bonded in supervisor 2 by tack coat, and fill filler 4 between supervisor 2 and honeycomb structure 3 and in six hollow regular hexagon bodies around a hollow regular hexagon body of honeycomb structure 3, the integral body after solidifying forms tower body 1; After connecting by flange 7 between tower body 1, be vertically arranged in the reinforced concrete foundation 5 that is embedded in level ground, and it is rear fixing to pour into cement 6; On tower body 1, also level is installed cross-arm 8, tower body 1 top water safety dress earth wire support 10.By at supervisor's 2 interior layout honeycomb structure 3 and fillers 4, can improve the integrated carrying ability of transmission tower.
Wherein, the position that cross-arm 8 and earth wire support 10 are set on tower body 1 is provided with connected node 9, and connected node 9 comprises stiffener 12 and junction plate 11, adopts welding or bolt to be connected between junction plate 11 and stiffener 12 and tower body 1; Cross-arm 8 is connected with connected node 9 by bolt with earth wire support 10.
Wherein, cement 6 is portland cement, take clay and limestone as raw material, through high-temperature calcination, obtains take the grog that calcium silicates is main component, then adds 3.5% limestone or granulated blast-furnace slag and the levigate hydraulic cementing materials of making of proper amount of gypsum; Its essential mineral forms: tricalcium silicate, dicalcium silicate, tricalcium aluminate, tetra calcium aluminoferrite.Tricalcium silicate is determining the intensity of portland cement in four weeks; Dicalcium silicate four stars after date is Developed fiber strength effect, reaches the tricalcium silicate Developed fiber strength in four weeks about approximately one year; Tricalcium aluminate intensity performance is very fast, but intensity is low, its to portland cement 1 to 3 day or slightly long-time in intensity play a role; The intensity performance of tetra calcium aluminoferrite is also very fast, but intensity is low, little to the intensity contribution of portland cement.The initial setting time 50min of portland cement, final setting time 310min.
Wherein, tack coat is comprised of epoxy resin and curing compound, and is mixed with a small amount of copper powder.
Wherein, filler 4 adopts cement and blowing agent to mix, and blowing agent is neutral substance.Concrete manufacturing process is, after being utilized to air compressor machine pressurization, cement blowing agent forms the foam with some tension, then foam and cement paste are stirred simultaneously, in whipping process, cement constantly expands, and then after adding setting accelerator in the cement after expanding, can fill.Cement adopts Portland cement more than 32.5R, and blowing agent adopts good fluidity, the vegetalitas blowing agent that amount of expansion is high, setting accelerator milliosmolarity between cement consumption 4% to 6% between; Meanwhile, should be higher than 3 ℃ to the on-the-spot temperature while filling filler 4 in supervisor 2 and honeycomb structure 3.
Wherein, the material that supervisor 2 adopts is steel or composite material.As adopt composite material can be by changing technique turn colors, make its outward appearance better and surrounding enviroment adapt.
Wherein, honeycomb structure 3 is welded for after high-strength steel sheet clod wash, and the mode that welding adopts is submerged arc welding; The sidewall thickness that forms seven hollow regular hexagon bodies of honeycomb structure 3 equates, at the sidewall of hollow regular hexagon body, evenly has manhole.
