Embodiment 1

[0034] Such as Figure 9 As shown, an assembled special-shaped column node includes a special-shaped column 1 and a beam 2 on both sides of the special-shaped column, and a joint energy dissipation device is provided at the connection between the special-shaped column 1 and the beam 2 on each side, such as the special-shaped column 1 It is a column with a cross-section; a limit energy dissipation device is provided at the two angles between the special-shaped column and the beam; for example Figure 10 As shown, the beams 2 on both sides of the special-shaped column are connected by tensioned prestressed steel rods 40, and the node energy dissipation device includes the third connecting steel plate 31, the fourth connecting steel plate 32 and the rubber pad 37, the third connecting steel plate 31 and the fourth connecting steel plate The four connecting steel plates 32 face each other, and the rubber pad 37 is located between the third connecting steel plate 31 and the fourth ...

Embodiment 2

[0048] Such as Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that two limiting plates 12 are welded on the outer wall of the outer cylinder 10, and the angle between the two limiting plates 12 is 90 degrees, and one of the limiting plates 12 Horizontally welded on the side of the outer cylinder 10 away from the special-shaped column 1, another limiting plate 12 is vertically welded on the side of the outer cylinder 10 away from the beam 2, and the two limiting plates 12 are respectively provided with two limiting holes 18, Two limiting holes 18 are arranged in the axial direction of the outer cylinder 10 , the axes of the limiting holes 18 are parallel to the axis of the outer cylinder 10 , and the two sections of the second chain 6 respectively pass through one limiting hole of the two limiting plates 12 .

Embodiment 3

[0050]The difference between this embodiment and Embodiment 1 is that this specific embodiment uses steel strands instead of tensioned prestressed steel rods, and the rubber pad 37 is located between the third connecting steel plate 31 and the fourth connecting steel plate 32. The rubber pad 37 is composed of two layers of rubber pads, the two layers of rubber pads are fixed between the third connecting steel plate 31 and the fourth connecting steel plate 32 through the fixing device, and the first steel cylinder 42 and the second steel cylinder 43 are respectively in the two layers of rubber pads , and the other structures are the same.

[0051] The sliding limit guide rail 13 in the foregoing embodiments can be a cage with multiple layers of balls or rollers, the cage is fixed on the outer cylinder 10, and the second chain 6 passes through the middle of the two layers of balls or rollers.

[0052] The working principle of the assembled special-shaped column node of the prese...

Abstract

The invention discloses a fabricated special-shaped column joint and a construction method. The fabricated special-shaped column joint comprises a special-shaped column and cross beams located on thetwo sides of the special-shaped column correspondingly. The connecting positions of the special-shaped column and the cross beams of both sides are each provided with a joint energy consumption device, and the at least one corner of the special-shaped column and the cross beams is provided with a limiting energy consumption device; and the cross beams on the two sides of the special-shaped columnare connected by tensioning prestressed steel bars. According to the construction method, driving chains are mounted by using a limiting adjusting scale, the anti-shearing stiffness at a beam-column joint can be improved, the structural stability is improved, the structural anti-deformation capacity is improved, and damage of earthquakes to a structure is reduced; and the mounting positions of thedriving chains can be accurately controlled under the natural states of the special-shaped column and the cross beams.

Description

technical field [0001] The invention relates to the field of building anti-seismic technology, in particular to an assembled special-shaped column node and a construction method. Background technique [0002] With the continuous expansion of the scale of residential buildings in my country and the vigorous advancement of the modernization of the housing industry, the multi-layer special-shaped column frame light-weight wall structure system with better building functions than ordinary frame structures has been gradually promoted and applied. The special-shaped column structure avoids the frame column protruding indoors, occupies less building space, and brings convenience to architectural design and use functions. The special-shaped column frame structure residence has good economic benefits, environmental benefits and social benefits, and shows good development prospects. [0003] my country is one of the land-earthquake-prone countries, especially in recent years, earthqu...
