Problems solved by technology

[0004] The purpose of the present invention is to overcome that the general solid structure in the prior art only produces elastic deformation and plastic deformation under the action of external load, and the force transmitted to the bottom support structure is also constantly changing, which cannot provide the bottom support structure with a maximum load of In view of the above shortcomings of the design threshold, a load-bearing structure and its design method are provided, and a support for the load-bearing structure, a joint assembly using the support, and a pipe joint using the joint assembly are also provided components

Embodiment 1

[0122] This embodiment provides a design method for the load-bearing structure 1. Under the external load, the maximum reaction force provided by the load-bearing structure 1 is its own design threshold, that is, when the external load is greater than the design threshold of the load-bearing structure 1 When the threshold is reached, the load-bearing structure 1 is deformed, and at the same time, it provides a reaction force with a design threshold value. The relationship between the magnitude of the reaction force load and the deformation displacement of the load-bearing structure 1 is as follows: figure 2 The shape of segment c of the middle curve.

[0123] The load-bearing structure 1 described in the present invention is an existing material structure, and the design threshold refers to the maximum reaction force that can be provided by the load-bearing structure 1 during the deformation process when the load-bearing structure 1 is subjected to an external load. The force...

Embodiment 2

[0133] Such as Figure 2-3 As shown, a load-bearing structure 1, the maximum reaction force provided by the load-bearing structure 1 under the action of an external load is its own design threshold, that is, when the external load is less than or equal to the design threshold of the load-bearing structure 1, The load-bearing structure 1 undergoes elastic deformation or / and plastic deformation, and provides a reaction force not greater than the external load; when the external load is greater than the design threshold of the load-bearing structure 1, the load-bearing structure 1 deforms, and provides a design Reaction force of threshold size.

[0134] The load-bearing structure 1 described in the present invention is an existing material structure, and the design threshold refers to the maximum reaction force that can be provided in a stable state or when deformation occurs when the load-bearing structure 1 is subjected to an external load. The reaction force refers to the rea...

Embodiment 3

[0147] This embodiment relates to the selection and testing of metal materials for the load-bearing structure 1 to meet the performance requirements.

[0148] 1. Primary selection of materials:

[0149] The selection of the load-bearing structure 1 (called the metal pressure-bearing column in this embodiment) needs to meet two basic conditions:

[0150] 1) The hardness is lower than that of steel and can be sheared by porous steel plates;

[0151] 2) Have sufficient corrosion resistance in the use environment;

[0152] Comprehensively considering the load and deformation requirements of the design for the shear key cushion, as well as the operating environment in which the shear key cushion works, the test materials for the shear key metal pressure-bearing columns initially selected include red copper, tin bronze, brass For copper and zinc, the main mechanical properties of each metal material used in the test are shown in the table below:

[0153] Table 1 The main mechanic...

Abstract

The invention discloses a load-bearing structure, a support, a joint assembly and a pipe joint assembly, wherein the load-bearing structure is under the action of an external load, and the maximum reaction force provided by the load-bearing structure is its own design threshold, that is, when the external load is greater than the load-bearing structure When the design threshold of the component is reached, the load-bearing structural component deforms and provides a reaction force of the design threshold; its support includes at least one load-bearing structural component, and the joint assembly and the pipe joint assembly are both provided with the support. When the external load is not high and is lower than the design threshold, the load-bearing structural member can effectively restrain deformation like a rigid structural member. When the external load exceeds the design threshold, it will deform, and at the same time provide a stable supporting reaction force lower than the external load. Load-bearing structural parts can be applied to supports, joint components and pipe joint components to protect the structure or key structural components, and can be widely used in bridge design, building structure design, tunnel design and other fields.

Description

technical field [0001] The invention relates to the technical field of bearing materials and structures, in particular to a bearing structure, a support adopting the bearing structure, a joint assembly and a pipe joint assembly. Background technique [0002] Deformable solids will deform under external loads. According to the characteristics of deformation, the mechanical behavior of general solids in the process of stress can be divided into two distinct stages: elastic deformation and plastic deformation. Among them, elastic deformation means that when the external force is less than a certain limit (usually called the elastic limit load), the solid can completely recover its original shape after the external force causing the deformation is removed. This recoverable deformation is called elastic deformation. , the stage where the solid only produces elastic deformation is called the elastic stage; plastic deformation means that once the external force exceeds the elastic ...
