Description

Technical Field

[0001] The utility model relates to an installation node of a self-insulating external wall panel for an assembled building, belonging to the technical field of assembled buildings. Background Technique

[0002] In the field of modern building walls, the self-insulating external wall panel is a new type of assembled wall material. Its structure mainly includes three parts. One part is a material layer with heat insulation and heat preservation performance, and the other two parts are reinforcement layers arranged on both sides of the material layer. As a material integrating the functions of an external enclosure wall, heat insulation, and heat preservation, the self-insulating external wall panel realizes the synchronous design, construction, acceptance, etc. of wall heat preservation and structure, and does not require secondary heat preservation construction, saving time and cost in construction, and is currently widely used in the construction field.

[0003] The installation process of the self-insulating external wall panel is relatively simple. Since one side of the self-insulating external wall panel is provided with a key and the other side is provided with a key groove, two adjacent self-insulating external wall panels can be spliced with each other through the key and the key groove. However, since the self-insulating external wall panel can be customized according to building requirements, when the height of the self-insulating external wall panel reaches or exceeds 4000 millimeters, the self-insulating external wall panel is prone to overturning. The reason is that the height of the key of the traditional self-insulating external wall panel is relatively low and the depth of the key groove is relatively shallow, and the biting effect and joint strength between two adjacent self-insulating external wall panels gradually decrease as the height of the wall panel increases. Moreover, when multiple self-insulating external wall panels are spliced to form an external wall, due to its overall height being relatively high and the biting effect and joint strength between two adjacent self-insulating external wall panels decreasing, the overall structural strength and anti-overturning ability of the external wall are relatively poor.

[0005] The technical scheme adopted by the utility model is as follows:

[0006] The installation node of the self-insulating external wall panel for an assembled building includes a limiting column with a rectangular cross-section shape. The limiting column is vertically arranged between two adjacent self-insulating external wall panels, and the bottom of the limiting column is connected to the main structure. The height of the limiting column is less than or equal to half of the height of the self-insulating external wall panel. Limiting grooves corresponding to the limiting column are respectively arranged on the opposite surfaces of the lower halves of two adjacent self-insulating external wall panels, and the limiting grooves on the opposite surfaces of the lower halves of two adjacent self-insulating external wall panels are spliced to form a limiting space, and the limiting column is located in the limiting space.

[0007] Preferably, the bottom of the limiting column is connected to the main structure through a pre-embedded part.

[0008] As a preference of the utility model, the inside of the limit post is filled with foamed polyurethane.

[0011] As a preference of the utility model, several steel bars are connected between the U-shaped metal parts on both sides of the self-insulating exterior wall panel.

[0012] As a preference of the utility model, the steel bars are connected with the U-shaped metal parts by plug welding through holes.

[0022] The following is a specific introduction to the utility model in combination with the drawings and specific embodiments.

[0023] As Figures 1-4 shown, this embodiment is an installation node of a prefabricated building self-insulating exterior wall panel, including a limiting column 1 with a rectangular cross-section shape, which is vertically arranged between two adjacent self-insulating exterior wall panels 2. The bottom of the limiting column 1 is connected to the main structure 3, and the height of the limiting column 1 is equal to half of the height of the self-insulating exterior wall panel 2. Of course, in actual application, the height of the limiting column 1 can also be slightly less than half of the height of the self-insulating exterior wall panel 2; on the opposite surfaces of the lower halves of two adjacent self-insulating exterior wall panels 2, limiting grooves 4 corresponding to and cooperating with the limiting column 1 are respectively arranged. The limiting grooves 4 on the opposite surfaces of the lower halves of two adjacent self-insulating exterior wall panels 2 are spliced to form a limiting space, and the limiting column 1 is located in the limiting space.

[0024] In this embodiment, the bottom of the limiting column 1 is connected to the main structure 3 through a pre-embedded part 5; the pre-embedded part 5 is composed of a steel plate and four anchor bars. The upper surface of the steel plate is on the same horizontal plane as the upper surface of the main structure 3, and the limiting column 1 is welded to the steel plate; in this embodiment, foamed polyurethane 6 is also filled inside the limiting column 1 to increase the heat insulation effect.

[0025] In this embodiment, the self-insulating exterior wall panel 2 is composed of a polystyrene particle board and lightweight concrete. On the opposite surfaces of the upper halves of two adjacent self-insulating exterior wall panels 2, a key 21 and a key groove 22 corresponding to and cooperating with each other are respectively arranged. The cross-section shapes of the key 21 and the key groove 22 are both semi-circular.

[0026] In this embodiment, the limiting groove 4 is a U-shaped metal part embedded in the side surface of the self-insulating exterior wall panel 2. The U-shaped metal part has a clamping effect on the limiting column 1. A plurality of steel bars 7 are connected between the U-shaped metal parts on both sides of the self-insulating exterior wall panel 2, and the steel bars 7 are connected to the U-shaped metal parts by plug welding through holes; of course, the number of the steel bars 7 can be appropriately increased or decreased according to the actual situation; the U-shaped metal parts on both sides of the self-insulating exterior wall panel 2 restrict each other through the steel bars 7.

[0027] When two adjacent self-insulating exterior wall panels 2 are spliced, the opposite surfaces of the upper halves of the two adjacent self-insulating exterior wall panels 2 are spliced through the corresponding key 21 and key groove 22, and the opposite surfaces of the lower halves of the two adjacent self-insulating exterior wall panels 2 clamp the limiting column 1 in the middle; the limiting column 1 has a certain limiting effect and anti-overturning effect on the two adjacent self-insulating exterior wall panels 2, improving the splicing joint strength of the two adjacent self-insulating exterior wall panels 2; when multiple self-insulating exterior wall panels 2 are spliced to form an exterior wall, the overall structural strength and anti-overturning ability of the exterior wall are significantly improved.
