Embodiment 1

[0034] Such as Figure 1-5 As shown, this embodiment takes two frame columns as an example to describe the structure of the high-position splicing energy-consuming beam-column node: a high-position splicing energy-consuming beam-column node, which consists of: an upper prefabricated frame column 1; a lower prefabricated frame column 2; Prefabricated frame beam 3; Energy dissipation board 4.

[0035] Wherein, the upper prefabricated frame column 1 and the lower prefabricated frame column 2 (ie, the support columns mentioned above), combined with the production, transportation and hoisting capabilities of the prefabricated components, adopt a two-layer or three-layer prefabrication. The splicing surface of the upper prefabricated frame column 1 and the lower prefabricated frame column 2 is set at a position that is less stressed and convenient for construction, and the height (H) from the floor is generally 1 / 4 to 1 / 3 of the floor.

[0036] Wherein, the upper prefabricated frame col...

Embodiment 2

[0049] This embodiment provides a construction method for high-position splicing energy-consuming beam-column nodes, including the following steps:

[0050] Step 1. When the upper prefabricated frame column 1 is prefabricated in the factory, a square steel tube 8 and a steel shoe 9 are pre-embedded at the bottom, and the embedded corrugated tube 19 forms a non-bonded prestressed rib tunnel, and the square outer tube 8 and the corrugated tube 19 are sealed. After the steel bars are tied up, the concrete is poured and cured;

[0051] Step 2. When the lower prefabricated frame column 2 is prefabricated in the factory, the shear key 10, the steel shoe 9 and the protective steel plate 12 are pre-embedded on the top, and the embedded corrugated pipe 19 forms a non-bonded prestressed tendon channel, the shear key 10 and the bellows 19 rooms are sealed, and bolt holes are provided at the position of connecting bolt 7. After the steel bars are tied up, the concrete is poured and cured. Th...

Abstract

The present invention relates to a high-level splicing energy-consuming beam column node and a manufacturing method. The node comprises a plurality of vertically arranged frame columns, wherein the plurality of frame columns are sequentially spliced in the vertical direction to form an integral structure, and the two sides of each frame column used for overlapping frame beams are provided with corbels respectively, each frame beam is lapped on each corbel, a floor panel are arranged on the upper end faces of the frame beams, and energy dissipation elements are arranged between the adjacent frame columns and between the frame columns and the frame beams respectively; and the frame columns with the corbels are supporting columns, and the height of the upper end surface of each supporting column to the floor panel is 1 / 4-1 / 3 of the floor height to achieve high-level splicing of the supporting columns and the upper frame columns above the supporting columns. According to the node, the field assembly quality and efficiency can be improved; and energy consumption plates improve the lateral stiffness of the structure and have moderate energy consumption capability, hear keys between the adjacent frame columns can limit horizontal displacement and rotation between the frame columns, and the redundancy and robustness of the structure are improved.

Description

Technical field [0001] The present disclosure belongs to the technical field of civil engineering, and specifically relates to a high-position splicing energy-consuming beam-column node and a manufacturing method. Background technique [0002] The prefabricated structure has the advantages of high degree of industrialization, material saving, low pollution, convenient construction, less on-site wet work, fewer workers, easy control of the quality of prefabricated components, short construction period, and quick return on investment. It is the direction of the industrialization of new buildings. . [0003] The inventor believes that the prefabricated concrete structure in the current project is still mainly equivalent to the cast-in-place assembled monolithic concrete structure, which dissipates seismic energy at the cost of component destruction and structural damage, and components and nodes under greater earthquake action Severe damage is very easy to occur, causing difficulty i...
