DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling unit for use in constructing a columnar structure such as an environmentally-friendly tower for high-voltage power transmission.

[0002] Conventionally, a high-voltage power for environmentally friendly towers, erected next to one another a plurality of pillar members on a base, linked via a Harizai each other該隣Ri <br/> fit pillar as the type of steel towers made, for example, FIG. 7, there is shown in FIG.

[0003] pillar pylons 13A shown in FIG 7 is formed by joining the flange joint 14 to pillar 13 ₁ and Hashirazai 13 ₂ of different diameters which are galvanized with each other. Further, the column member pylons 13B shown in FIG. 8 is formed by joining the same diameter pillar 13 ₃ and Hashirazai 13 ₄ welded joints 15 each other which are galvanized.

[0004]

However [0007] In the conventional upper and lower pillar 13 ₁ and 13 _2, 13 ₃ and 13 _4, the joint portion for the column member bonded to the (flange joint 14, weld joint 15) Beams The joint part 16 for joining the members is provided to be separated in the axial direction of the column member. Further, one of the pillars 13 ₁ and 13 ₂
So, since it constitutes the pillar members joining the joint portion in the flange joint 14, it is necessary to provide a large-scale joint flange pillar 13 ₁ and 13 ₂ of each of the opposed ends. Also, the other pillar 13 ₃ and 13 _4, since it constitutes the pillar members joining the joint portion in the welded joint 15, not only providing the welding backing member 13 _4a to the lower end of the upper column member 13 ₄ , on the inner surface of the upper end of the lower column member 13 _3, it is necessary to provide the flange 13 _3a for receiving the backing member 13 _4a. Therefore,
Each of the column members 13 ₁ and 13 ₂ and the column members 13 ₃ and 13 ₄ requires labor and cost for manufacturing.

Further, when the column material of the tower 13A is constructed, it is only necessary to fasten the joint flange with a large number of bolts, but the material cost of the joint flange, the cost of mounting on the column material and increasing the weight are required. Was a problem.
When constructing the pillar of the steel tower 13B, the pillar 13
After tacked by ₃ and 13 ₄ of the opposite ends erection piece 13 _3a and 13 bolts and nuts between _4a splice plate 13 _5a attached at regular intervals in each circumferential direction on the outer surface of the temporary welding (splice plate 13 _5a perform welding) for securing the upper column member 13 ₄ until circumferential welding remove the, thereafter, subjected to circumferential welding, it must then blown removing the erection piece 13 _3a and 13 _4a Therefore, the efficiency of construction site work is poor.

[0025] In the hot-dip galvanizing, the welding location of the unit pillar 3 ₁ (3 _2, 3 ₃₎ Unit pillar is welded to the joint portion 6 ₁ of 3 ₂ (3 _3, 3 ₄₎ by a masking or the like An unplated portion is formed to prevent the weld bead from becoming brittle with the zinc component in the hot-dip galvanized after welding.

When constructing the high-voltage power transmission tower 1, first,
The two unit column members 3 ₁ and 3 ₁ are opposed to each other and each joint 6
After forming the gate-shaped by bonding Harizai 4 to _1, basic 2 anchor base 9 provided at the lower end of the unit pillar 3 ₁ and 3 ₁
And anchor constructing the unit pillar 3 ₁ and 3 ₁ by anchor bolts 10 is brought into contact with the upper. Then, the first coupling flange 6a provided at the joint end of these units pillar 3 ₁ and 3 ₁ in the annular receiving portion 6a _s, the same manner as described above portal formed by the unit column members 3 ₂ and 3 ₂ of The backing material 8 for welding provided at the joint end is brought into contact with the unit column members 3 ₁ , 3 ₁ and 3 ₂ , 3 _2.
And the first joint flanges 6a, 6
They joined together by welding of a and upper unit column members 3 _2, 3 _2. By repeating the above-mentioned vertical stacking and welding of the unit column members, a plurality of unit column members are joined to form the base 2
The pillar 3 is built on top.

[0027] In order to bind a pair of upper and lower units pillar members 3 ₁ to be joined 3 _2, 3 ₂ and ₃ 3, 3 ₃ and 3 ₄ to each other, one of the unit pillar 3 _{2 (3} 3, 3 ₄₎ first coupling flange 6a provided at the joint end and the other units pillar 3 ₁ (3 _2, 3 ₃₎
Since welding bets, 3 (1), if the unit pillar 3 ₁ shown in (2) and 3 ₂ vertically overlap unit pillar as is the same diameter to each other, and FIG. 4 (1) , the bondable easily even when a different diameter vertical overlapping unit pillar to each other as shown in (2) to the unit column members 3 ₂ showing a 3 _3, 3 ₃ and 3 _4. In the case of different diameters, as shown in FIG. 4 (3), it is preferable to form the column member 3b constituting the upper end of the lower unit column member into a tapered tube.

Further, the axial force acting on the column member 3 of the constructed high-voltage power transmission tower 1 is one unit column member 3 ₂ (3 ₃ ,
Smooth transmission is achieved via the joint between the 3 ₄ ) and the first joint flange 6 a provided on the other unit column member 3 ₁ (3 ₂ , 3 ₃ ).

[0029]

Further, the unit column member 3 _1, 3 _2, 3 _3, 3 ₄ was constructed in a circular cross section of the tube, it may be constituted by polygonal section of the tubular body of course.

Furthermore, lower unit pillar material 3 ₁ (3 _2, 3 ₃₎ the joint portion ₆₁ is provided at an upper end portion of,該継hand portion 6 ₁ of the first upper unit pillar 3 to the joint flange 6a ₂ (3 _3, 3 ₄₎ has been welded to the lower end of, as shown in FIG. 5, the upper unit column members 3 _{2 (3} 3, 3
₄₎ The joint portion ₆₁ provided at the lower end of welding the first coupling flange 6a of該継hand portion ₆₁ to the upper end of the lower unit pillar 3 ₁ (3 _2, 3 _3), a first coupling flange The second joint flange 6b may be arranged above the 6a.

Although the number of pillars 3 to be constructed is two, three or four pillars, for example, as shown in FIG. 6 , may be used.

[0033]

As described above, according to the present invention, of the pair of upper and lower unit pillars joined to each other, the backing material for welding is fixed to at least the inner surface of the joining end of one of the unit pillars, and the other. After attaching the first joint flange and the second joint flange joined to each other via a web plate at the joint end of the unit column material, the unit column material is inclined to the hot dip galvanizing solution in the plating tank. Immersion and take out in an inclined state after plating is completed, allowing the plating solution to freely enter and exit into each unit column material, and reliably obtaining a hot-dip galvanized assembled unit as before. Can be. Also,
The number of joints can be reduced by using the first joint flange, which forms a part of the joint for beam joining, for joining the unit column members, and the welding back surface provided on one of the unit column members. The patch can be received by the annular receiving portion of the first joint flange provided on the other unit column member, and the conventionally separately provided flange can be omitted. Therefore, the assembling unit can be manufactured with less labor.

Further, the annular receiving portion of the first joint flange provided at the joining end of the other unit column material and the welding backing material provided at the joining end of the one unit column material are brought into contact with each other so as to make the pair. The first joint flange is welded to the other unit column material regardless of whether the two unit column materials have the same diameter or different diameters, and Unit pillars can be easily combined. Therefore, the efficiency of the construction work of the columnar structure can be improved as compared with the conventional case where the column members are directly welded to each other.

Further, the axial force acting on the column material of the constructed columnar structure is applied via the joint between the one unit column material and the first joint flange provided at the joint end of the other unit column material. It can be transmitted smoothly. Therefore, assembling strength of the columnar structure can be ensured as in the conventional case.
