Cable fittings lever clamp tool hoop

 Called Hold hoop hoop hoop is made of a material or hoop hold another material components. It belongs to the fasteners. Hoop device consists hoop plate, flange, Rachel ribs, bolts and inner liner constitution. Hoop has a good variety, cable hoop, hoop poles, cable hoop, hoop hanging wire, stainless steel hoop are more commonly used. An Embedded hoop, it is by the left and right halves of the hoop After the connection is made together, left and right halves sheet showed a semicircular hoop ring, half ring ends bent outward, each forming a mounting ears, characterized in that: the left end of the sheet hoop mounting ears On opened embedded slots, corresponding with its mate right sheet hoop provided with mounting ears on the corresponding pin end and right end piece hoop installation pin embedded on the left ear piece attached to one end hoop embedded slots in the ears Influence hoop installation quality factors: 1, the hoop must not have holes, trachoma, shrinkage cracks and other defects. 2, material and performance seals must comply with the requirements, the sealing surface may not have bubbles, inclusions, cracks, uneven and other defects, you can not use the aging of the rubber ring. 3, moving away from the snap ring in the British rivet head hoop theoretically half the amount of stretching of the joint, to the measured real amount, if it is not, then the amount of stretching can not meet the requirements of the pipeline. In order to promote permit sealing effect, the factory and British jets hoop supporting the rivet head end of the tube around, the actual project should not use ordinary pipe directly instead of end of the tube, and the flatness of the end of the tube end and the axis of verticality and the end itself has certain requirements , size is not standard makes the telescopic joint greatly reduced amount, can not meet the requirements. 4, the end of the tube diameter size to choose a positive bias, or clamp ring pressing force is not enough to affect the joint seal. ? Usually 1:75 models of RC pole pole hoop size formula: Q (mm) = L (mm) ÷ 75 + q (mm) Q:? Hoop dimensions (mm) L:? From bar top height (mm) q:? pole mast diameter (mm) cement poles in accordance with section may be divided into square, octagonal, I-shaped, circular or some other shaped cross-section poles, which is more commonly used in the country ring of reinforced concrete pole. An annular tapered concrete poles can be divided into equal diameter rod and bar, slightly tapered rod diameter is generally φ150mm-φ470mm, taper 1:75, wall thickness around 50mm; equal diameter rod outer diameter generally φ300mm-φ400mm wall thickness is also about 50mm. Requires a lot of different kinds of time in the installation of overhead lines or poles accessories hoop, waiting for that big hoop when the rod diameter is relatively simple, you can know the exact path a little. When tapered pole mount hoop, hoop size is too large if you need iron in stuffed; if hoop is too small, the hoop and poles can not fit, if moving up and down hoop, it will affect the vertical dimension of the electrical fittings, showing a position to know the size of the tapered rod is necessary for installation. In general, by standardizing portfolio to see what hoop size, but the hands of urban and installation of the staff are not standardized portfolio, even if the hands of a portfolio, the above are also some typical standardized hoop installation size, In reality construction, many owners need a pole for non-standard installation, the portfolio is difficult to find; on the other hand, various national standard hoop expensive, a lot of the construction team will be tailored according to the size themselves, not only On cost-effective, the installation will be handy. Here we give you to talk about the relative size calculated diameter hoop poles and for the majority of the power construction sector construction and installation can proceed smoothly. First, know a little diameter wire rod (the thinnest end of the diameter), bottom diameter poles how calculated? We can bottom diameter of formula (bottom diameter = L / 75 + slightly diameter) to obtain, which is the bottom diameter refers to the diameter of the bulk of poles, L is the total length of the poles means, refers to the smallest diameter slightly poles diameter end . For example: a pole known as GB Circular Prestressed poles, model φ190-12m, seeking the pole bottom diameter. Solution: slightly diameter of 190mm, a length L of 12000mm, the bottom diameter = 12000/75 + 190 = 350mm Second, a little known diameter poles, how calculated diameter from pole top anywhere? This is our time to install hoop often used algorithms, method of calculating the specific algorithm base diameter less the same as above, is calculated as D1 = L1 / 75 + a little path, where D1 is any position from the pole tip diameter, L1 is the length of anywhere from pole top, slightly diameter of the smallest diameter of the pole end. For example: Known pole model φ190-15m, according to the pole to be placed on top of 1200mm a hoop, seeking hoop diameter. Solution: hoop diameter = 1200/75 + 190 = 206mm, so you need hoop diameter of 206mm. Third, in any one knows poles diameter, find the distance at a location diameter. When a position is above any one time (ie, closer to the pole head position), D1 = D2-L1 / 75; when a position below the one located at any time (ie, closer to the bulk pole position), D1 = L1 / 75 + D2. Ask for the location where the diameter D1 group, L1 is a straight line from the known position and the position of the demand, D2 is a known location diameter. In fact, the size of the utility pole and hoop diameter to calculate the original aim, which is calculated are D1-D2 = L / 75. This calculation rule applies to all taper 1:75 taper rod in future construction installation, we can utilize this formula based on the hope that the wire rod size calculation method can help you!
