Embodiment Construction

[0027] Such as figure 1 Shown is a landmark tower for the specific application of the present invention. The sign tower is in the shape of a slanted triangular pyramid. Below 73m is composed of three inclined tower columns, and above 73m is composed of 3 steel pipes. The angle between one leaning tower and the bottom is 99.68°, and the angle between the other two and the bottom is 64.69°.

[0028] Such as figure 2 Shown is a schematic diagram of the foundation of the three pillars of the landmark tower applied by the present invention. The foundation part of the steel structure landmark tower is composed of three concrete foundation piers 10, 20, and 30. Each foundation pier carries the column foot of the landmark tower through three main bearing points, as shown in the figure, including bearing points 1, 2 , 3, 4, 5, 6, 7, 8, 9, and piers 10 and 20 correspond to the above two leaning tower columns with an angle of 64.69° to the bottom surface. Because the steel tower is under b...

Abstract

This invention discloses a method for balancing tilting major structure overthrow force with the basic weight form, which comprises the following steps: a) combining the inclined main body and the foundation structure as an integrated structure, counterweigh designing the basic structure; b) declining the gravity height of the integrated structure, adjusting it to the geometry center of the foundation structure; c) adjusting the forced state in the foundation structure, integrating the different piers which connect the inclined main body in the foundation structure to a whole; d) allocating the lever prestressed reinforcement in the beam, balancing the outward thrust of the pier through the lever prestressed force; allocating vertical prestressed reinforcement in the pier with vertical pull force, balancing the prestressed force of the pier through the vertical prestressed force.

Description

Technical field [0001] The invention relates to a basic structure construction technology of a high-rise structure, in particular to a basic structure construction technology of an inclined high-rise structure that generates overturning force. Background technique [0002] The high-rise structures at home and abroad mainly include TV towers, radio towers, microwave towers, transmission line towers, tourism, sightseeing, and memorial towers. They are mainly divided into steel structures and reinforced concrete structures (including prestressed concrete structures). Among them, the steel structure has the following advantages: high steel strength, good plasticity and toughness, homogeneous isotropic properties, weldability and assembly, good overall stability, and light overall weight. [0003] Use function Facade form Representative project Main construction technology During construction Between TV Tower Straight tower...
