Embodiment 1

[0033] Example 1: A new fully assembled concrete steel frame node.

[0034] refer to Figure 1-7 , the present invention includes prefabricated concrete columns 3 arranged vertically, and rectangular vertical steel pipes 4 are pre-embedded in the node areas of the prefabricated concrete columns 3 . Both sides of the vertical steel pipe 4 are welded with horizontal H-shaped steel 5, on the web of the horizontal H-shaped steel 5 near the end of the vertical steel pipe 4, there are several vertically arranged through holes, and the two horizontal H-shaped steel 5 The through holes correspond horizontally one by one. A column stirrup 8 is pierced in two through holes on the same horizontal plane respectively to form a column stirrup net around the vertical steel pipe 4 .

[0035] The end of the horizontal H-shaped steel 5 away from the precast concrete column 3 is provided with a horizontally arranged precast concrete beam 1, and the end of the precast concrete beam 1 close to t...

Embodiment 2

[0039] Embodiment 2: The construction method of the new fully assembled concrete steel frame joint.

[0040] Such as Figure 8 As shown, the construction method of a novel fully assembled concrete steel frame node of the present invention comprises the following steps:

[0041] S1, making beam end section steel: welding stud 6 on one end web of beam end H section steel 2, and setting bolt holes for bolt connection on the other end web;

[0042] S2. Making node section steel: set bolt holes for bolt connection on one end of the horizontal H-shaped steel 5, and weld the other end with the column wall of the rectangular steel pipe 4, wherein the horizontal H-shaped steel 5 web is provided with a column hoop The through hole through which the rib 8 passes, and a vertical triangular stiffener 7 is welded between the column wall of the rectangular steel pipe 4 and the flange of the horizontal H-shaped steel 5;

[0043] S3. Binding the beam body frame: binding beam longitudinal rei...

Abstract

The invention relates to a novel fully-fabricated concrete profile steel frame joint and a construction method thereof. The novel fully-fabricated concrete profile steel frame joint comprises a vertically-arranged prefabricated concrete column, a rectangular vertical steel pipe is pre-embedded in a joint area of the prefabricated concrete column, pieces of horizontal H-shaped steel are welded to the two sides of the vertical steel pipe correspondingly, triangular stiffening ribs are arranged at the junctions of flange plates of the horizontal H-shaped steel and the column wall of the verticalsteel pipe, and a plurality of through holes are formed in web plates of the end, close to the vertical steel pipe, of the horizontal H-shaped steel; a plurality of column stirrups surrounding the vertical steel pipe is arranged in a mode of penetrating through the through holes; and the ends, away from the vertical steel pipe, of the horizontal H-shaped steel are in bolted and welded connection with beam-end H-shaped steel pre-embedded at prefabricated concrete beams. The novel fully-fabricated concrete profile steel frame joint is creatively put forwards, and is good in anti-seismic performance, high in structure integrity, concise and attractive in design, and convenient to assemble on site.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a novel fully assembled concrete steel frame node and a construction method thereof. Background technique [0002] With the development of modern industrial technology, my country has begun to vigorously develop prefabricated buildings and promote the adjustment and upgrading of industrial structure. Compared with traditional cast-in-place structures, prefabricated buildings have the advantages of fast construction progress, high production efficiency, labor saving, and improved construction quality. However, my country's prefabricated buildings started late, and the technology is relatively backward. The reason for this is the key node connection problem, poor structural integrity and seismic performance, and inconvenient node construction. [0003] For prefabricated concrete structure systems, the connection mode between prefabricated components is one of the core ...
