Description

Iron tower variable cross-section built-up joint
Technical field
The utility model belongs to the technical field of iron tower of power transmission line, relates in particular to the technical field that angle steel tower master material variable cross-section node connects, and is specially iron tower variable cross-section built-up joint.
Background technology
Some bear the iron tower of power transmission line and the general single heavy in section angle steel or the steel tubular structure of adopting of communication iron tower main material of big load at present, in design, run into the iron tower load when very big, can suitably extenuate main material bearing load by becoming sloping enlarging section size, but increase iron tower cross section span simply, to cause the auxiliary material specification obviously to increase, can cause the iron tower foundation root to hold simultaneously and become big, increase is taken up an area of on the basis, will influence the overall aesthetics and the safety of iron tower like this, so the mode of this kind bearing load is subjected to certain restriction.In addition, the single main material connection of also normal at present employing becomes two main materials connections or two main material connects change four main material ways of connecting, solve the big problem of load, when conversion, realize connection between the main material with joint, this joint is for adopting the form of cross weld holder, and the defective of its existence is, after the conversion of main material quantity, the skewness of load can not well play the effect of sharing load.
The utility model content
The purpose of this utility model is to provide a kind of practicality good iron tower variable cross-section built-up joint at the defective of above-mentioned existence, this joint adopts and comprises the cross-wire weld fishplate bar, also comprise fixed head, wherein said cross-wire weld fishplate bar is welded in two surfaces up and down of fixed head, this joint adopts integral solder fully by the technical scheme that bolt is connected with main material, and processing technology is simple, install and convenient transport, can be applied on the various electric pressure iron towers.
The technical solution of the utility model is: iron tower variable cross-section built-up joint, comprise the cross-wire weld fishplate bar, and it is characterized in that also comprise fixed head, wherein said cross-wire weld fishplate bar is welded in two surfaces up and down of fixed head, this joint is connected with main material by bolt.
Characteristics of the present utility model also have: be welded with the stretching fixed head on the described cross-wire weld fishplate bar; This joint integral body is Type of Welding.
The beneficial effects of the utility model are: this iron tower reduced section sub is provided with fixed head, the form of structure of welding cross-wire weld fishplate bar on the fixed head, realized that single main material connects the two main materials connections of change or two main material connection becomes four main materials connections, and load has reached uniform by fixed head, eliminate the problem of former load distribution inequality, brought into play the ability of the bearing load of main material to greatest extent.The utility model adopts integral solder fully, and processing technology is simple, installs and convenient transport, can be applied on the various electric pressure iron towers, and practicality and strength character is good, and stability is strong, and is simple in structure, good looking appearance.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of single main material when becoming two main material.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the upward view of Fig. 1.
Wherein, 1 is single main material, and 2 is two main materials, 3 welded plates for the single main material in fixing upper end, and 4 is junction plate, and 6 is fixed head, and 7 is upper end cross-wire weld fishplate bar, and 9 are the stretching fixed head, and 10 is bolt, and 11 is lower end cross-wire weld fishplate bar.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in detail.
This iron tower variable cross-section built-up joint comprises the cross-wire weld fishplate bar, also comprises fixed head 6, and wherein said cross-wire weld fishplate bar is welded in two surfaces up and down of fixed head 6, and this joint is connected with main material by bolt 10.
Be welded with stretching fixed head 9 on the described cross-wire weld fishplate bar.
This joint is whole for the convenient transportation of Type of Welding, installation and construction, is applicable to that the iron tower main material cross section is the angle steel structure.
As Fig. 1, Fig. 2, Figure 3 shows that a kind of Application Example of the present utility model, from Fig. 1 as can be seen, this carries out bolt 10 with single main material 1 above built-up joint and is connected, below carry out bolt 10 with two main materials 2 and be connected, single main material 1 is fixed by the welded plate 3 of the single main material in fixing upper end, and be provided with junction plate 4, connect with bolt.
As shown in Figure 2, be welded with upper end cross-wire weld fishplate bar 7 at fixed head 6 upper surfaces, wherein, be welded with stretching fixed head 9 on this upper end cross-wire weld fishplate bar 7, it is fixing to play a part to stretch.
As shown in Figure 3, be welded with lower end cross-wire weld fishplate bar 11 at fixed head 6 soffits, wherein, be welded with stretching fixed head 9 on this lower end cross-wire weld fishplate bar 11, it is fixing to play a part to stretch.
The utility model is a kind of machine made integral solder joint, is applicable to the different cross section angle steel, can select suitable connecting hole size and size according to the main material specification and the directrix of iron tower design use.
