Technical Field
The utility model relates to a column wallboard thickness is 80mm, and stiffening rib is thick to be equal to or is greater than 80 mm's super thick wall board steel tower segment and connects structure for 60 mm's column wallboard thickness, belongs to the steel tower segment field of making.
Background
In recent years, steel cable towers are more and more favored by bridge builders, and are divided into connection forms, and the steel towers built in China are mainly divided into 'metal contact + high-bolt connection' combined stress steel towers and welded steel towers. The welded steel tower is generally used as a city bridge landscape structure, in order to shorten the construction period, improve the anti-seismic performance and highlight the landscape effect, the height of the tower is generally not more than 100m, the design requirement is that the axis deviation of the steel tower installation is not high, the steel plate mostly adopts a thin plate or a medium plate (the thickness is 30 mm), the field girth welding is mostly carried out in a strong constraint state (the horse plates are used for rigid fixation in a large amount), the damage to the base metal is serious after the horse plates are removed after welding, and the linear precision control of the steel tower installation is not high.
Disclosure of Invention
The design purpose is as follows: the defects in the background technology are avoided, and the ultra-thick wall plate steel tower segment connection structure with the thickness of the tower column wall plate being 80mm and the thickness of the stiffening rib plate being 60mm is designed.
The design scheme is as follows: in order to achieve the above-mentioned objects. The utility model discloses in structural design: the circular seam grooves of the upper tower section wall plate and the lower tower section wall plate of the steel tower segment are asymmetric K-shaped grooves, welding materials are filled in the circular seam grooves and connect the upper tower section wall plate 3-1 and the lower tower section wall plate 3-2 in a welding mode, namely the steel tower segments are welded in a penetration welding mode, and the linear requirement of a tower column reaches the requirement of 1/4000.
Compared with the prior art, the utility model, tower section wallboard, lower tower section wallboard circumferential weld groove are asymmetric K type groove on the steel tower segment, and the installation of effective control steel tower segment is linear, and whole cable wire tower installation is linear to reach 1/5000, is far less than axis deviation 1/4000's designing requirement, has initiated the welding of thick wall plate steel tower structure, has not only promoted product quality standard, has reduced welding variable moreover, need carry out the thermal correction very seldom or almost reach standard requirement.
