Abstract
The utility model discloses a cold-bending thin-wall 60 DEG angle steel microwave tower which comprises a tower post and a belly rod which are connected together, wherein the tower post is a cold-bending thin-wall 60 DEG angle steel, and the cross section of a tower frame composed of the connected tower post and the belly rod is a triangle; the tower post is made of cold-bending thin-wall 60 DEG lipped angle steel, and the belly rod is made of cold-bending thin-wall channel steel or lipped channel steel. The utility model uses cold-bending thin-wall 60 DEG angle steel and the cold-bending thin-wall 60 DEG lipped angle steel, so the number of components is reduced about one fourth and steel products is saved more than 40 percents, compared with a quadrangle angle steel tower; the structure of a node is simple, the number is reduced and the engineering work load of field installation is reduced.
Description
Technical field
The utility model relates to moving communicating field, is a kind of supporting structure of microwave transmitting and receiving apparatus, the pylon structure of 60 ° of angle steel of particularly a kind of cold bending thin wall.
Background technology
Over year, along with the develop rapidly of mobile communication cause, China newly sets up ten hundreds of microwave pylons every year surplus in the of nearly ten, and its main version mostly is the angle steel tower, and promptly king-post and web member mainly adopt the pylon that common hot-rolled angle steel is made.Because two limits of common hot-rolled angle steel are the right angle, so the body of the tower cross section mostly is quadrilateral, and the shortcoming of quadrilateral angle steel tower is:
1) quadrangular section is a geometrically unstable system, is a geometrically stable system for guaranteeing stressed tabula face, and body of the tower needs to be provided with the tabula of putting more energy into every 2～3 tower sections, and the two ends that become place, slope, microwave antenna suspension place, delivery unit at king-post should be provided with tabula.Therefore compare with the triangular-section, quadrilateral pylon cross section has increased the material of tabula and making, erected cost.
2) quadrangular section has increased the web member of a leg of angle and a facade, and not only steel using amount increases, and has increased number of nodes and field erected workload.
3) adopt common hot-rolled angle steel, king-post splicing node place, interior cornerite steel needs back-off, has increased to make and the splicing mounting hardness.
Summary of the invention
The purpose of this utility model is to provide 60 ° of angle steel microwaves of a kind of cold bending thin wall pylon, can reduce structural steel consumption, node number of connection and on-site installation work amount, thereby reduces microwave tower shelf structure cost, makes that it is simple in structure, sets up conveniently.
The technical solution of the utility model is achieved in that
The utility model comprises king-post, web member, and king-post links to each other with web member, and king-post is 60 ° of angle steel of cold bending thin wall, and the pylon xsect that king-post and web member are connected to form is a triangle.
King-post is 60 ° of lipped angles of cold bending thin wall.
Web member adopts cold bending thin wall channel-section steel or lipped channel.
The utility model is by adopting 60 ° of angle steel of cold bending thin wall or 60 ° of lipped angles of cold bending thin wall, and it is about 1/4 to make the number of components of the present utility model compare will lacking of quadrilateral angle steel tower, saves steel more than 40%; Joint structure is simple, quantity reduces, and significantly reduces on-the-spot installation work amount.

Fig. 2 is a facade structures synoptic diagram of the present utility model;
Fig. 3 (a) is 60 ° of angle steel synoptic diagram of cold bending thin wall of the present utility model;
Fig. 3 (b) is 60 ° of lipped angle synoptic diagram of cold bending thin wall of the present utility model.
Embodiment
Accompanying drawing is a specific embodiment of the utility model;
Below in conjunction with accompanying drawing content of the present utility model is described in further detail:
Shown in Fig. 1,2, cold bending thin wall angle steel microwave pylon comprises king-post 1 and web member 2, adopt bolt to be connected between king-post 1 and web member 2 connected nodes, form the space pylon structure, its xsect is a triangle, and wherein king-post 1 adopts 60 ° of angle steel of cold bending thin wall or 60 ° of lipped angles of cold bending thin wall.
The pylon xsect that king-post 1 and web member 2 are connected to form is a triangle, makes pylon structure more stable, saves material, reduces cost.
Shown in Fig. 3 (a) and (b), king-post 1 adopts 60 ° of angle steel of cold bending thin wall or 60 ° of lipped angles of cold bending thin wall.Because sheet steel can be bent into 60 ° of angle steel or lipped angle by cold working, so pylon structure can be made up of three limbs, and king-post 1 can directly link to each other by bolt with web member 2, and the pylon xsect that king-post 1 and web member 2 are connected to form is a triangle.The cold bending thin wall cross section is very economic section form simultaneously, and single construction weight is light, is easy to carrying, and fabrication and installation are easy, and overall economic efficiency is very remarkable.
