Embodiment Construction
[0027] The present invention will be further described below in conjunction with specific embodiment:
[0028] Such as Figure 1-7 Shown is a roll support that releases displacement in a single direction and its angle of rotation. The support is mainly composed of a base plate subsystem, a roller shaft subsystem, a limit subsystem, and a protection subsystem; among them, the base plate subsystem is the pre-embedded steel plate (lower base plate) of the corbel top, column top or beam top, trestle, bridge or truss and other bottom reserved steel plate (upper base plate); the roller axis subsystem is composed of hollow roller 1, shaft 2 set in the hollow roller, horizontal plate and vertical plate; the limit subsystem is composed of limit plate and The pin bolt key is formed; the protective subsystem is composed of connecting angle steel 13, hinge 14, and protective plate 15. It is characterized in that: the steel plate (lower base plate) is pre-embedded on the top of the corbe...

The invention relates to a roller bearing capable of releasing displacement in a single direction and its rotation angle and its method, which belong to a roller bearing for reducing gap setting and eliminating temperature stress in reinforced concrete structures, steel structures, and the like. The support includes a substrate subsystem, a roller subsystem, a limit subsystem and a protection subsystem; wherein, the substrate subsystem is composed of a lower substrate and an upper substrate; the roller subsystem is composed of a hollow roller, a shaft set in the hollow roller, It is composed of two horizontal plates and two pairs of vertical plates, and the vertical plates are provided with oval holes; the limit subsystem is composed of a pair of limit plates and a pair of pin keys; the protection subsystem is composed of connecting angle steel, hinges and protective panels. The invention provides a support form with the advantages of economical applicability, convenient construction, stress reduction, etc., which can ensure that the bearing position of the engineering structure is not damaged and can move in one direction. The setting of long-span bearings for structural, industrial and civil building systems.
Description
technical field [0001] The invention relates to a roller bearing capable of releasing displacement in a single direction and its rotation angle, relates to a manufacturing method thereof, and belongs to a roller bearing for reducing gap setting and eliminating temperature stress in a reinforced concrete structure, a steel structure, and the like. Background technique [0002] With the development of social construction technology, especially the needs of economic and cultural development, more and more new structural forms are gradually applied to civil and industrial buildings. In the past two decades, long-span structures have developed rapidly in developed countries such as the United States, Japan, and Europe, and many new technologies and materials have been adopted to promote the progress of long-span building structures. In civil, industrial, and bridge engineering, it is increasingly approaching the use of long-span structures in order to save space and beautify the ...
