Problems solved by technology

[0003] When the external temperature of the steel structure changes greatly, it is easy to generate temperature stress inside, resulting in deformation of the steel structure. At present, the best way to release the temperature stress is to set a hinged support at the end of the steel structure. The traditional hinged support is The nodal sphere is in direct contact with a spherical inner cavity, and an opening for accommodating steel structural rods is reserved on the upper part of the spherical inner cavity, and the temperature stress is released through the rotation of the nodal sphere in the spherical inner cavity. However, due to the spherical cavity and The nodal spheres are in direct contact, and while the nodal spheres are rotating, more heat is generated due to friction, which affects the release of the temperature stress of the steel structure. Therefore, a hinged support that can avoid frictional heat generation and the use of the support is provided. Steel structure node hinged structure to meet demand

Embodiment 1

[0025] see Figure 1-3 , the embodiment of the present invention provides a hinged support, including a support base 2, a left clamp 9 and a right clamp 4, the left clamp 9 and the right clamp 4 have the same structure, and are used to splice to form a hinged chamber , the supporting base 2 is fixedly installed on the upper part of the concrete foundation 1, and the upper part of the supporting base 2 is provided with a card slot 3 for accommodating the left card holder 9 and the right card holder 4.

[0026] The installation and fixation of the hinged support is realized by embedding the left clamping base 9 and the right clamping base 4 used for splicing to form the hinged chamber into the clamping groove 3 and cooperating with the fixed connection between the supporting base 2 and the concrete foundation 1 .

[0027] The bottom of the hinged chamber is movably provided with a supporting plate 10, and the supporting plate 10 is in a bowl-shaped structure; the upper part of t...

Embodiment 2

[0031] see figure 1 And with reference to Embodiment 1, in the embodiment of the present invention, a steel structure node hinged structure based on the use of the above-mentioned hinged support includes a steel structure member 6 and a node sphere 5 fixedly connected to the bottom of the steel structure member 6. The nodal sphere 5 is embedded in the hinged chamber, and the bottom of the nodal sphere 5 is attached to the supporting plate 10 , and an oil immersion cavity 8 is formed between the nodal sphere 5 , the left clamping seat 9 and the right clamping seat 4 .

[0032] The nodal sphere 5 is separated from the hinge chamber by the supporting plate 10, so that the nodal sphere 5 can freely rotate on the supporting plate 10, and meanwhile the supporting plate 10 can also slide in the hinged chamber, which improves the rotation flexibility of the steel structural member 6, The temperature stress generated by the steel structure rod 6 can be eliminated faster; the lubricatin...

Abstract

The invention provides a hinged supporting seat, and belongs to the technical field of steel structural connection. The hinged supporting seat comprises a surrounding supporting base, a left clampingseat and a right clamping seat, the left clamping seat and the right clamping seat have same structures and used for splicing to from a hinged chamber, the surrounding supporting base is fixedly mounted on the upper part of a concrete foundation, and a clamping groove used for accommodating the left clamping seat and the right clamping seat is formed in the upper part of the surrounding supportingbase; and a supporting plate is movably arranged at the bottom of the interior of the hinged chamber, and a movable opening is formed in the upper part of the hinged chamber. According to the hingedsupporting seat, the supporting plate is movably arranged in the hinged chamber to bear a joint sphere, compared with the prior art, contact area of the joint sphere and the hinged chamber is reduced,it is guaranteed that steel structural rod pieces are connected stably while the speed of temperature stress release of the steel structural rod pieces is improved, and the higher practical value isachieved.

Description

technical field [0001] The invention relates to a technical field of steel structure connection, in particular to a hinged support and a steel structure node hinged structure using the support. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, and adopts rust removal and antirust processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. The components or components are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, stadiums, super high-rises and other fields. [0003] When the external temperature of the steel structure changes greatly, it is easy to generate temperature stress inside, resulting in deformation of the steel s...
