Description
Technical Field
The invention belongs to the technical field of prefabricated building, and relates to a modular assembled steel structure building connection system and a construction method thereof.
Background
In recent years, the nations are greatly pushing civil building construction to be low-carbonization, green, industrialized and intelligent, and in the great background of carbon emission reduction in the whole society industry, a modularized steel structure building structure is receiving attention of industry by virtue of unique advantages compared with the traditional building structure, and the advantages of the modularized steel structure building structure include: the construction speed is high, and the construction time is short; the method can be used for factory prefabrication, has controllable quality and less resource waste, and greatly reduces carbon emission; internal pipeline laying, equipment installation and other internal decorations can be performed in advance, and the construction period of a building is greatly shortened.

From the standpoint of node strength and rigidity, most of the above connection modes are in a "semi-rigid connection" state or a "flexible connection" state, which makes it difficult to raise the height of the modular building upwards. From the angle of the connection area, the existing connection mode enables the module units to be integrally formed only through the mutual connection of the corners, a 'stacked beam multi-column' state is formed, columns are connected at column ends only, and no reliable horizontal connection exists at other positions, so that the combined column cannot cooperatively bear force, the whole section is large, and material waste and complex force are caused.

The modular assembled steel structure building connection system according to claim 5, further comprising a connection plate for fixing the node connection piece, wherein a strip-shaped hole for facilitating the horizontal connection of the column II is formed in the middle of the connection plate, symmetrical rectangular holes are formed in two sides of the strip-shaped hole, and the node connection piece is inserted into the rectangular hole.
7. The modular fabricated steel structure building connection system of claim 6, wherein the rectangular holes are adapted to the shape of the grooves formed by the C-stiffener.
8. The modular fabricated steel structure building connection system of claim 7, wherein the node connection is one of a cross-section connection, a square tube section connection, an H-section connection, or a channel section connection.
9. The modular fabricated steel structure building connection system of claim 8, wherein the ceiling beams and floor beams are rectangular section steel beams.
10. The method of constructing a modular fabricated steel structure building connection system of claim 9, comprising the steps of:
s1, butting C-shaped open ends of two adjacent module columns in the horizontal direction, inserting the two adjacent module columns into a column horizontal connecting sleeve I, and connecting the adjacent module columns in the horizontal direction through the column horizontal connecting sleeve I to enable the adjacent module columns to be combined columns;
s2, inserting a column horizontal connection sleeve II above the column horizontal connection sleeve I, and simultaneously assembling a beam end connecting piece on a ceiling beam at the upper end of the combined column, wherein one end of a shear pin resistant on a middle ear plate of the beam end connecting piece is inserted into a beam end opening on the ceiling beam;
s3, inserting the node connecting piece into the connecting plate, sleeving the connecting plate inserted with the node connecting piece on the column horizontal connecting sleeve II, enabling the connecting plate to be level with the middle lug plate of the beam end connecting piece, and pouring concrete into the assembled combined column to enable the combined column formed by the module columns to be connected into an integral cooperative stress;
s4, after the assembly of the combined columns on the same layer and the installation and concrete pouring of various connecting pieces are completed, the module of the upper layer is hoisted, after the new module of the upper layer is hoisted, the horizontal connection of the left and right adjacent module columns and the installation of the beam end connecting pieces are carried out, namely, the grouting is carried out after the other ends of the shear pins are inserted into the beam end holes on the floor beams of the corresponding module columns, and thus, the assembly grouting is carried out along the length direction and the height direction of the module columns in a reciprocating manner.
