Description

Technical Field

[0001] The present invention relates to the technical field of green prefabricated building production, and in particular to a green prefabricated building node structure. Background Art

[0002] With the rapid development of the construction industry and the enhancement of environmental awareness, green prefabricated buildings have gradually become an important development direction in the construction field due to their advantages such as fast construction speed, low environmental pollution and high resource utilization. However, in the actual application of prefabricated buildings, the stability and functionality of the node structure often become the key factors restricting its widespread promotion. The traditional prefabricated building node structure has many shortcomings in terms of structural strength, ventilation performance, cable management and construction convenience, which makes it difficult to meet the diversified needs of modern buildings for green, efficient and intelligent.

[0003] Specifically, the structural strength of traditional node structures often relies on a large amount of on-site welding and concrete pouring, which not only takes a long construction period, but also easily leads to quality risks. At the same time, the node structure has poor ventilation performance, which easily leads to a decline in indoor air quality and affects the health of residents. In addition, chaotic cable management is also a major drawback of traditional node structures, which not only affects the appearance, but also increases the difficulty of later maintenance and repair. Summary of the invention

[0004] The purpose of the present invention is to provide a green assembled building node structure in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A green prefabricated building node structure comprises an outer wall, an inner wall and a floor slab, wherein a crossbeam is arranged at the upper end of the outer wall near one side of the inner wall, the floor slab is mounted on the crossbeam and the inner wall, and the outer wall extends upward away from the inner wall and wraps around the floor slab; trapezoidal openings are arranged on the upper parts of the four edges of the floor slab, the floor slab is docked with the outer wall at the position where the floor slab is docked to form a first pouring area, and the floor slab is docked with the trapezoidal opening of the adjacent floor slab at the position above the inner wall to form a second pouring area; an upper wind trough is provided on the upper part of the outer wall near one side of the inner wall, and a lower wind trough is provided on the lower part, the upper wind trough and the lower wind trough are connected by a connecting pipe, and are connected to an external air supply system through an air inlet pipe.

[0007] Preferably: shutters are installed at the opening positions of the upper wind slot and the lower wind slot.

[0008] Preferably: a wire box is installed inside the upper wind slot and the lower wind slot.

[0009] Preferably, a waistline is provided on a surface of the outer wall away from the inner wall at a position corresponding to a joint between two upper and lower adjacent outer walls.

[0010] Preferably: a pre-buried wire tube and a pre-buried air duct are pre-buried in the third pouring area, the pre-buried wire tube is connected with the wire box for wiring, and the pre-buried air duct is used to connect the air inlet pipe, the upper air slot, and the lower air slot.

[0011] Preferably: a first connecting steel bar is fixedly installed on the crossbeam, and its upper end extends to the first casting area; main floor slab connecting bars are pre-embedded inside the floor slab, and the first connecting steel bar extends to the first casting area near one end of the outer wall, and the first connecting steel bar extends to the second casting area near one end of the inner wall; a second connecting steel bar is pre-embedded at the upper end of the inner wall, and its upper end extends to the second casting area.

[0012] Preferably: the crossbeam is an I-beam, and the gap between the I-beam and the outer wall and the floor slab forms a third pouring area, and the third pouring area is arranged close to the inner wall and flush with the outer wall surface; the lower end of the first connecting steel bar is welded to the I-beam.

[0013] Preferably: the cross beam is a cast beam, which is arranged on the upper part of the outer wall close to the indoor side, the cast beam is pre-embedded with embedded steel bars, and the lower end of the first connecting steel bar is pre-embedded in the cross beam.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Stable structure: The present invention forms a stable supporting structure by arranging a crossbeam at the upper end of the outer wall and erecting a floor slab on the crossbeam and the inner wall. At the same time, the first pouring area formed by the trapezoidal opening design on the four edges of the floor slab and the outer wall, and the second pouring area formed by the floor slab and the trapezoidal opening of the adjacent floor slab above the inner wall further enhance the integrity and stability of the node structure. In addition, the first connecting steel bar fixedly installed on the crossbeam, the main floor slab connecting steel bar embedded inside the floor slab, and the second connecting steel bar embedded at the upper end of the inner wall together constitute a stable connection system, ensuring the stability and safety of the node structure when bearing various loads.

[0016] 2. Good ventilation: The present invention sets an upper trough and a lower trough on one side of the outer wall close to the inner wall, and connects the two through a connecting pipe. In summer, cold air is blown in from the upper trough, and the cold air falls to quickly achieve a cooling effect in the room; conversely, in winter, hot air is blown in from the lower trough, and the hot air floats upward to quickly achieve a heating effect in the room; at the same time, the shutters installed at the openings of the upper trough and the lower trough can adjust the ventilation volume as needed to prevent debris from falling in; this design not only improves the indoor air quality, but also helps to reduce building energy consumption and achieve green energy saving;

[0017] 3. Orderly cable management: The present invention pre-buries pre-buried wire tubes and pre-buried air ducts in the third pouring area, which are used in conjunction with the wire box and air duct on the outer wall to achieve orderly arrangement of cables and ventilation ducts; the pre-buried wire tubes are connected to the wire box for wiring, ensuring the neatness and beauty of the cables and easy maintenance; the pre-buried air ducts are used to extend the air inlet duct to connect the upper air duct and the lower air duct, achieving smooth operation of the ventilation system; this design not only improves the overall aesthetics of the building, but also reduces the difficulty of later maintenance and overhaul;

[0018] 4. Convenient construction: The present invention adopts the concept of prefabricated design, prefabricates and standardizes the main components of the node structure, and then assembles and casts them on site; this construction method not only shortens the construction period, but also reduces the construction difficulty and cost; at the same time, since the stability and functionality of the node structure are fully guaranteed, the construction quality and building safety can be ensured.
