Description
Technical Field
The utility model relates to a climb flange joint tower node reinforcing apparatus in single tube.
Background
The communication towers built by Chinese iron towers and third parties and stocked by operators are collectively called stock iron towers; by 12 and 31 months in 2018, 194.8 million total station sites of the Chinese communication iron tower exist, the communication iron tower structure is divided into a truss tower, a guyed tower, a single-pipe tower, a roof tower and the like, wherein the connection of the single-pipe tower sections mainly adopts two modes of inner flanges and splicing connection, the conservative estimation is carried out, and the number of the flange single-pipe towers in the existing stock is more than 10 million.
According to the planning of the Ministry of industry and communications, China iron tower companies are established for the main purpose of improving the sharing rate of base stations, and with the arrival of 5G, stock iron towers need to bear 2G \3G \4G \5G four-frequency-band devices of three families of China Mobile, Unicom and telecom, the number of antennas mounted on a single iron tower is required to be more than 18 at least, and generally more than 27 pairs are required, while the stock iron towers are basically switched from operators, and when the operators build, the demands of the current self-use frequency bands are basically considered, and the bearing capacity of the mast after the antennas are added is generally increased according to the mounting consideration of 9-18 pairs of antennas.
At present, the shared reconstruction of the domestic single-pipe tower is realized by reducing additional loads of a platform, a camouflage cover, a lamp and the like to replace a newly added antenna load, or the tower height is reduced to reduce the tower height so as to reduce the service performance, and the application range is narrow.
Through the experience analysis of reinforcement and transformation engineering in recent three years, after the single-pipe tower is subjected to increased mounting, the strength of flange rib plates and flange connecting bolts in tower body flange nodes is insufficient, and the single-pipe tower flange node reinforcement technology is not an effective technology. The reinforcing device for the single-pipe internally-climbing flange connecting tower node can effectively solve the problem that the strength of a flange rib plate and a flange connecting bolt in the existing tower body flange node is not enough.
Disclosure of Invention

The utility model adopts the technical proposal that:
the utility model provides a single pipe internal climbing flange joint tower node reinforcing apparatus which characterized in that: the long anchor ear is coated on the outer surface of an inner climbing flange connecting tower node and uniformly coated on the upper tower section and the lower tower section by taking a flange node binding face as a central line. The utility model discloses a long staple bolt redistribution flange node's atress form avoids producing the not enough condition emergence of flange gusset and flange connecting bolt intensity in the interior flange node of climbing of tower body.
Further, the thickness of the long anchor ear is equal to the wall thickness of the tower section where the flange joint is located.
Further, the length of the long anchor ear is equal to 3 times of the outer diameter of the flange.
Furthermore, the surface of the circular arc plate is provided with a lifting lug plate.
Furthermore, the two sides of the arc plate are respectively provided with a connecting plate, and the adjacent connecting plates are fixedly connected through bolts.
Furthermore, a plurality of reinforcing plates are arranged between the outer surfaces of the connecting plates and the outer surfaces of the arc plates, so that the reliability of connection between the adjacent arc plates is guaranteed.
The utility model has the advantages that: the outer surface cladding through climbing flange joint tower node has long staple bolt, the atress form that changes the node is by single flange pressurized in the past, when crooked, the power at its pressurized edge is by the section of thick bamboo wall, the inside and outside welding seam transmission between gusset and the flange board, change into at the flange pressurized, thereby it is curved also to bear the pressure to bend to change the reinforcing apparatus simultaneously and reach the atress form that changes the node and solved the problem that flange gusset and flange connecting bolt intensity are not enough in the tower body flange node, it is reasonable to have simple structure simultaneously, low cost, be applicable to the node reinforcement.
