Description

Technical Field

[0001] The utility model relates to the technical field of green steel structure wallboard production, in particular to a node of green steel structure columns, beams and wallboards. Background Art

[0002] In the modern construction industry, with the continuous improvement of the requirements for sustainable development, energy conservation and emission reduction, green prefabricated buildings have attracted more and more attention due to their advantages such as fast construction speed, small environmental impact and high resource utilization rate. However, the traditional prefabricated building node structures often have problems such as insufficient connection strength, poor seismic performance and complex construction, which seriously restrict the development and application of prefabricated buildings.

[0003] Especially in the connection nodes between the floor slab and the wall, the traditional construction methods often rely on a large number of on-site operations, such as welding and bolt connection. These methods not only increase the construction difficulty and cost, but also may cause problems such as cracks and water seepage at the connection parts, thus affecting the overall performance and durability of the building.

[0004] Therefore, developing a new type of green prefabricated building floor slab node structure to improve the connection strength, simplify the construction process and enhance the seismic performance has become an urgent technical problem to be solved in the current construction field. Content of the Utility Model

[0005] The purpose of the utility model is to provide a node of green steel structure columns, beams and wallboards in order to solve the above problems.

[0006] The utility model realizes the above purpose through the following technical solutions:

[0007] A node of green steel structure columns, beams and wallboards, including an outer wall, an inner wall and a floor slab. A cross beam is arranged on the upper end of the outer wall close to one side of the inner wall, the floor slab is erected on the cross beam and the inner wall, and the outer wall extends upward on the side far from the inner wall to wrap the floor slab; trapezoidal openings are arranged on the upper parts of the four peripheries of the floor slab, a first casting area is formed at the butt joint position between the floor slab and the outer wall, and the trapezoidal openings of the floor slab at the position above the inner wall are butted with the adjacent floor slabs to form a second casting area.

[0008] Preferably: waistlines are arranged on the surface of the outer wall on the side far from the inner wall corresponding to the positions of the joints between two adjacent outer walls up and down.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Enhanced connection strength: By setting a first pouring area at the joint between the outer wall and the floor slab, and setting a second pouring area between the floor slabs, and pouring concrete in these two areas, the connection between the floor slab and the wall is made stronger, significantly improving the connection strength of the node;

[0014] 2.

Combined with the cross arrangement of the first connecting steel bar, the main reinforcement of the floor slab connection and the second connecting steel bar, a more integrated seismic system is formed, which effectively improves the seismic performance of the building;

[0015] 3. Simplify the construction process: The present invention adopts a combination of prefabricated components and on-site casting, which reduces the amount of wet work on site, simplifies the construction process, and improves construction efficiency. At the same time, due to the reasonable design of the connection nodes, the complexity and uncertainty in the construction are reduced, and the construction difficulty and cost are reduced;

[0016] 4. Improve the aesthetics of the building: A waistline is set on the surface of the outer wall away from the inner wall, corresponding to the joint position of the upper and lower adjacent outer walls, which not only enhances the overall aesthetics of the building, but also can cover up the defects at the joints to a certain extent, thus improving the overall quality of the building;

[0017] 5. Promote the development of green buildings: The node structure of the present invention adopts the design concept of green prefabricated buildings. Through factory production and on-site assembly of prefabricated components, it reduces the generation of construction waste and waste of resources, which is in line with the development trend and requirements of green buildings.

[0026] As Figure 1 shown, a green steel structure column, beam, and wall panel joint includes an outer wall 1, an inner wall 7, and a floor slab 4. A cross beam is provided on the upper end of the outer wall 1 near one side of the inner wall 7, and the floor slab 4 is erected on the cross beam and the inner wall 7. The outer wall 1 not only serves as the external enclosure structure of the building, but also jointly supports the floor slab 4 with the inner wall 7 through the cross beam provided at its upper end. This design effectively disperses the weight of the floor slab 4 and enhances the stability of the overall structure. The side of the outer wall 1 away from the inner wall 7 extends upward to wrap the floor slab 4; trapezoidal openings are provided on the upper edges of the four perimeters of the floor slab 4. These trapezoidal openings not only facilitate effective docking with adjacent floor slabs 4, but also provide space for concrete flow and anchoring during the pouring process, further enhancing the connection strength between the floor slabs 4. A first pouring area 8 is formed at the docking position between the floor slab 4 and the outer wall 1, and the floor slab 4 forms a second pouring area 9 at the position above the inner wall 7 by docking with the trapezoidal openings of the adjacent floor slabs 4.

[0027] A waistline is provided on the surface of the side of the outer wall 1 away from the inner wall 7 corresponding to the joints of two adjacent outer walls 1 up and down.

[0028] A first connecting steel bar 3 with its upper end extending into the first pouring area 8 is fixedly installed on the cross beam; main floor connecting steel bars 5 are pre-buried inside the floor slab 4. One end of the first connecting steel bar 3 close to the outer wall 1 extends into the first pouring area 8, and one end of the first connecting steel bar 3 close to the inner wall 7 extends into the second pouring area 9; a second connecting steel bar 6 with its upper end extending into the second pouring area 9 is pre-buried at the upper end of the inner wall 7; the first pouring area 8 is located at the docking position between the floor slab 4 and the outer wall 1, and the poured concrete can effectively bond the floor slab 4 and the outer wall 1 tightly to form an integral body. The second pouring area 9 is located between the floor slabs 4. By filling the trapezoidal openings with concrete and connecting the first connecting steel bar 3, the main floor connecting steel bars 5, and the second connecting steel bar 6, a powerful seismic resistance system is constructed. Both the first connecting steel bar 3 and the second connecting steel bar 6 include interconnected horizontal steel bars and vertical steel bars.

[0029] The cross beam is an I-beam 2. A third casting area 10 is formed at the gap positions between the I-beam 2, the outer wall 1, and the floor slab 4. The third casting area 10 is arranged flush with the surface of the outer wall 1 on the side close to the inner wall 7. The lower end of the first connecting steel bar 3 is welded to the I-beam 2. Concrete is poured into the first casting area 8, the second casting area 9, and the third casting area 10. After the concrete solidifies, a firm connection node is formed.

[0030] Pipes are arranged on both side surfaces of the inner wall 7, the inner side of the outer wall 1, and the floor slab 4. The pipes are respectively connected to the rooftop radiator and the underground cooling and heating system. The rooftop radiator is used for heat dissipation, and the underground cooling and heating system is used for cooling or heating the indoor environment. The medium is water or gas. Embodiment 2

[0031] As Figure 2 shown, the difference feature between this embodiment and Embodiment 1 is that: the cross beam is a cast beam, which is arranged on the upper part of the outer wall 1 close to the indoor side. Embedded steel bars 11 are pre-buried inside the cast beam. The lower end of the first connecting steel bar 3 is pre-buried in the cross beam. The cast beam 11 can be customized according to the actual on-site situation, better adapting to the complexity and diversity of the building structure. In addition, the cast beam 11 has stronger integrity and a closer connection with the floor slab 4 and the outer wall 1, which is beneficial to improving the overall performance and seismic resistance of the structure.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
