Abstract
The utility model discloses an iron tower with a large specification, which comprises three or more main supporting rods, and reinforcing rods which are arranged among the main supporting rods, wherein the cross section of each main supporting rod comprises two pieces of L-shaped supporting angle steel with butted angle parts, and a piece of reinforcing angle steel is fixedly arranged between the two pieces of supporting angle steel. The iron tower with the large specification, which adopts the structure, has the advantages that the bearing capacity is high, the main supporting rods are not liable to deform, the on-site assembly is easy, and the erection and the transport are convenient.
Description
Technical field
The utility model relates to a kind of transmission facility, relates in particular to a kind of big specification iron tower.
Background technology
In the electric power course of conveying; Need to use electric power pylon; Electric power pylon not only will carry the weight of lead itself; Also need carrying lead frame to be located to bear when aerial receive each to wind-force, and the extra pressure that causes because of situation such as conductor glaze formations, so the design bearing capacity of electric power pylon must be far above the weight of lead itself.
Increase the bearing capacity of iron tower, best means are exactly size and the thickness that increases the steel that constitute iron tower, are assembled into big specification iron tower; And electric power pylon tends to be set up in the remote mountain areas, and the electric power pylon of big specification is not only manufactured trouble, and transports, sets up extremely inconvenience; Especially as the main support rod of iron tower main support structure, need be criss-cross steel bar through being welded to form cross section often, add four blocks of angle steel again and reinforce formation by four block plates; Size is huge, and it is more inconvenient to transport, as installing at the construction field (site); The multiple working procedure that then welds and reinforce has strengthened difficulty of construction, the equipment that increase need be carried.
The utility model content
The utility model provides a kind of big specification iron tower easy to use for solving the prior art problem.
The technical scheme of the utility model is: a kind of big specification iron tower; Constitute by three or three above main support rods and the bracing piece that is arranged between the main support rod; The cross section of said main support rod comprises the L shaped support angle steel that two bights offset, and is set with the reinforcement angle steel between two said support angle steel.
Expect by four original block plates that welded construction changes to by two and support that angle steel offset and through strengthening the structure that angle steel is reinforced; Omitted original welding sequence; Assembling speed is fast, efficient is high, guarantees that simultaneously existing support strength is not less than original support strength.
As preferably, said strut angle ladle draw together two vertical each other, be flat support edge.
As preferably, said reinforcement angle steel comprise two vertical each other, be flat stiffened edge.
Two right angles support angle steel and offset each other; Strengthen angle steel through two right angles and reinforce, having formed cross section is criss-cross main support rod, and the main support rod of this structure is saved material most on the basis of the bearing capacity that guarantees sufficient intensity; Have higher side direction supporting capacity simultaneously, not yielding.
As preferably, the inboard of the connecting portion of two said support edges is provided with circular chamfering.Angle steel is processed through flap by the monoblock steel plate, and the knuckle place is circular chamfering, and the angle steel of this structure has higher anti-lateral deformation ability, and bearing capacity is stronger.
As preferably, the arranged outside of the connecting portion of two said support edges has to the limit.Two are supported angle steel through having offseting to the limit of certain width, are difficult for dislocation, be easy to install, and firmness are good after the installation, and not yielding, bearing capacity is strong.
As preferably, be mutually permanently connected through screw bolt and nut between said support angle steel and the reinforcement angle steel.
As preferably, be mutually permanently connected through screw bolt and nut between said bracing piece and the main support rod.
The fixed structure easy accessibility of screw bolt and nut, set up at the scene of not only being convenient to, and be corroded in the monolithic steel and be easy to change after aging.
In sum, the utlity model has following advantage:
1, the big specification iron tower bearing capacity of this structure is strong, and main support rod is not yielding;
2, the big specification iron tower of this structure is easy to assembled on site, sets up and convenient transportation.
Description of drawings
Fig. 1 is former iron tower main support rod cross section structure sketch map;
Fig. 2 is the utility model main support rod cross section structure sketch map.
Among the figure, 1, support angle steel, 11, chamfering, 12, the support edge, 13, support the limit, 2, strengthen angle steel, 21, stiffened edge, 3, bolt, 4, nut.
The specific embodiment
With embodiment the utility model is described further below.
Embodiment one:
A kind of big specification iron tower is made up of four main support rods and the bracing piece that is arranged between the main support rod, and is as shown in Figure 2, and the cross section of main support rod comprises that 1, two in L shaped support angle steel that two bights offset supports to be set with between the angle steel 1 and strengthens angle steel 2; Support angle steel 1 and comprise that two connecting portion inboards vertical each other, that be 12, two support edges 12, flat support edge are provided with circular chamferings 11, arranged outside has to the limit 13, strengthen angle steel 2 comprise two vertical each other, be flat stiffened edge 21; Support between angle steel 1 and the reinforcement angle steel 2 and be mutually permanently connected through bolt 3 and nut 4.
Wherein, two support edge opposite sides are regarded as the inboard, otherwise then are regarded as the outside.
When setting up, two limits 13 of supporting of supporting angle steel 1 are offseted, reinforcement angle steel 2 is close in the outside; Supporting angle steel 1 and strengthening penetrating bolt 3 between the angle steel 2, and fastening through nut 4, and constituting cross section is criss-cross main support rod; Process four successively with main support rod, and main support rod is holded up, put into ground stabilization; Between adjacent main support rod, add bracing piece, form complete iron tower.
