Embodiment Construction

[0043] The present invention is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0044] figure 1 The illustrated embodiment is an elevation view of the overall structure of the spanning structure of the present invention applied to a bridge structure. Specifically, the spanning structure whose upper arch amplitude can be automatically adjusted is composed of a main structure 1 and a fixed support 2. The fixed support 2 is connected to both ends of the main structure 1 to constrain the linear displacement of the two ends of the main structure. The main structure 1 is composed of multiple The space truss segments 3 are connected, the number of the space truss segments 3 can be determined according to the actual demand, and the increase of the arch amplitude of the main structure 1 can be realized by increasing the longitudinal length of the space truss segments 3 .

Abstract

The invention relates to the technical field of the civil engineering and relates to a crossing structure. The crossing structure comprises a main body structure and a fixed bearing, wherein the fixed bearing is connected with both ends of the main body structure; and the main body structure is formed by connecting a plurality of space truss sections. Under the specific conditions, the cross structure can utilize an automatic synchronous jack device to drive a transverse telescopic connecting rod to be synchronously shortened (or extend), so that the longitudinal length of a horizontal crossed connecting rod is increased (or decreased) and the space truss sections longitudinally extends (or is shortened) along the structure, and thus, the integral crossing structure longitudinally extends (or is shortened) along the structure and the effect of automatically regulating the arch-up amplitude of the crossing structure is implemented. According to the invention, in the case of the specific conditions or in the case that the outside environment is changed, normal functions of the crossing structure are played and the safety and the practicality of the structure are ensured.

Description

technical field [0001] The invention relates to the technical field of civil engineering, and relates to a spanning structure. Background technique [0002] Spanning structures mainly include bridges, roofs and ceilings of long-span buildings. During the use of the spanning structure, some special situations may be encountered, and the external environment may also change continuously. It is necessary for the structure to automatically adjust the arching range according to different situations and environments to ensure its normal function. [0003] For example, when the bridge structure encounters sudden floods and the height of navigable ships increases, it is necessary to increase the height of the bridge deck or the clearance height under the bridge without interrupting the normal operation of the structure, and increase the arching range of the beam body to ensure the passage of vehicles. The safety of people and people and the navigation requirements of bridges; when ...
