Horizontally adjustable stiff support of lattice framed structure

Abstract

The invention discloses a horizontal rigidity adjustable support with a grid structure. The support comprises a support ball joint, grid components, a cross-shaped rib plate, a support base plate, ananchor bolt, a sliding chute, a sliding plate, a support steel tube, a pre-embedded steel plate and a lower structure. A steel plate, the sliding plate and the support base plate are respectively arranged on the pre-embedded steel plate in sequence; the cross-shaped lib plate is arranged on the support base plate; the support ball joint is arranged on the cross-shaped lib plate; the plurality of grid components are arranged on the support ball joint; the support steel tube is arranged in the horizontal direction of the circle center passing through the support ball joint; the other end of thesupport steel tube is connected with a rigidity adjusting device; the sliding chute is arranged on the support base plate; the anchor bolt matched with the sliding chute is arranged on the pre-embedded steel plate; and the anchor bolt respectively penetrates through the steel plate, the sliding plate and the support base plate. The support has the advantages that the adjustment and the optimization of the horizontal rigidity of the support can be realized; the reaction force and the horizontal displacement of the horizontal rigidity adjustable support with the structure can be effectively controlled; and the mechanical performance of the structure under the actions of temperature, earthquake and dynamic loading can be improved to a certain extent.

Description

technical field [0001] The invention relates to a grid structure, in particular to a horizontal adjustable rigidity support of the grid structure. Background technique [0002] The grid structure is widely used in large public and industrial buildings, such as stadiums, airports, exhibition halls and large industrial production rooms. It is currently the most common structural form used in long-span building structures in my country. With the rapid development of my country's economy and culture, the shapes of long-span buildings are becoming more and more novel and complex, and their functions are becoming more and more diversified, which also makes their design loads more and more heavy. All of these put forward higher requirements for structural design work. . Complex building surfaces and increased service loads often lead to excessive horizontal reaction force or horizontal displacement of the support under the commonly used support conditions in the past, which is diff...

Problems solved by technology

[0005] In addition to the above two commonly used support structures, a domestic patent for a "universal support" that provides a horizontal spring structure has also been developed, but the position of the spring layout is at the bottom of the support, and the horizontal reaction force The direction does not pass through the center of the spherical node of the support, so it will bring adverse effects on the eccentric force of the support, and this eccentric state will also increase the error between the theoretical calculation and the actual structure, which will lead to the actual formation of the horizontal support. The deviation between the seat stiffness and the ideal value that the theoretical design wants to achieve

Therefore, its performance in providing accurate support horizontal stiffness needs to be improved
