Large-span arched venue structure system

Abstract

The invention provides a large-span arched venue structure system. Two main arch frames, two secondary arch frames, a waist truss, a top truss and a top arch frame are mutually connected to form a main arch frame body, lateral and vertical loads transmitted by a large-span cambered surface roof steel structure frame are effectively borne, and supporting side columns at the other end of the large-span cambered surface roof steel structure frame, I-shaped pile bearing platforms at arch feet and a row pile foundation formed by hole digging piles are combined, so that the building structure appearance of an unfolded book is realized, and meanwhile, the stability is extremely high. Besides, the upper structure adopts the main arch frames and a secondary arch structure to transfer force and consume energy mutually, the lower foundation adopts I-shaped bidirectional row piles with prestress straining beams and anti-pushing retaining walls to resist bidirectional horizontal pushing force of arch feet, the upper structure and the lower foundation are organically combined to form self-balance of an integral structure system, the size of components can be effectively reduced, materials are saved, and the building space impression is improved.

Description

technical field [0001] The invention relates to a building structure system, in particular to a large-span arched building structure system. Background technique [0002] A city in the west of China needs a citizen service center. In order to show the design concept of "recording the book of city history and connecting the bridge of Eurasia", the architectural shape needs to be similar to an open book, and it also needs to have an administrative service center, planning The four major functions of the exhibition hall, the science and technology museum, and the big data center are to realize the architectural functional requirements of the service system of "open office, one-stop service, and one-stop settlement". Shaped roof, and both sides are inclined to the central axis of the building, and the common building structure at the central axis is difficult to bear the lateral load of the roofs on both sides.

[0002] A city in the west of China needs a citizen service center. In order to show the design concept of "recording the book of city history and connecting the bridge of Eurasia", the architectural shape needs to be similar to an open book, and it also needs to have an administrative service center, planning The four major functions of the exhibition hall, the science and technology museum, and the big data center are to realize the architectural functional requirements of the service system of "open office, one-stop service, and one-stop settlement". Shaped roof, and both sides are inclined to the central axis of the building, and the common building structure at the central axis is difficult to bear the lateral load of the roofs on both sides

[0003] In addition, citizen service centers generally need to be built in urban areas, which are easily surrounded by municipal roads, and the foundations of such long-span arched structures are often large in size, which is easy to cause damage to the subgrade of municipal roads
