Embodiment Construction

[0027] Such as figure 1 Shown is a sign tower of the specific application of the present invention. The sign tower is in the shape of an inclined triangular pyramid. Below 73m, it is composed of three leaning tower columns, and above 73m, it is composed of three steel pipes. The angle between one leaning column 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 the schematic diagram of the foundation of the three column feet of the sign tower applied in the present invention. The foundation part of the steel structure sign tower is composed of three concrete foundation piers 10, 20, 30, and each foundation pier bears the column feet of the sign tower through three main bearing points, including bearing points 1 and 2 as shown in the figure , 3, 4, 5, 6, 7, 8, 9, pier 10, 20 correspond to the above two tensioned inclined tower columns with an angle of 64.69° to the bottom surface, because the steel tow...

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 the foundation structure construction technology of towering structures, in particular to the foundation structure construction technology of inclined towering structures generating overturning force. Background technique [0002] The towering structures at home and abroad mainly include TV towers, radio towers, microwave towers, transmission line towers, tourism, sightseeing, and memorial towers, which 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, weldable and assembling, good overall stability, and light overall weight. [0003] See the table below for an overview of high-rise buildings using "steel structures" at home and abroad. [0004] [0005] [0006] The linear or folded straight towers of the...
