Description

Technical Field

[0001] The utility model relates to the technical field of design and construction of assembled external wall panels, and more specifically, to a novel external wall panel installation node. Background Art

[0002] With the continuous development and advancement of construction technology and building material performance, more and more engineering structural designs are adopting precast concrete exterior wall panels, which are prefabricated in factories and installed on-site. Precast concrete exterior wall panels are non-load-bearing precast concrete exterior wall panels installed on the main structure to provide enclosure and decoration. Precast concrete exterior wall panels are a subsystem of prefabricated buildings and are widely used in concrete frame structures, steel structures, and cast-in-place exterior systems. They can be industrially produced in factories and undergo high-temperature and high-pressure treatment and surface pre-coating processes to ensure excellent weather resistance and decorative effects.

[0003] Currently, because external wall panels are not the primary load-bearing components in prefabricated structural systems, these systems generally rely on the main structure to bear vertical and horizontal loads, while the wall panels do not participate in the load-bearing process. However, under the influence of wind and earthquakes, the wall panels in such structures will shift relative to the main structure to a certain extent, inevitably causing damage and destruction to the connection nodes, resulting in reduced durability of the connection parts, and further causing partial wall panel detachment, posing a certain degree of safety hazard. Secondly, external wall panels generally use four-point or six-point connections. However, the existing node structure is complex, inconvenient to construct, and difficult to repair if problems arise during subsequent use. Utility Model Content

The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention. That is, the present invention is not limited to the described embodiments.

[0025] In order to better understand the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments:

[0026] See also Figure 1 and Figure 2 As shown, the utility model provides a new type of exterior wall panel installation node, including an exterior wall panel 1 and a main structure 2, the exterior wall panel 1 and the main structure 2 are fixedly connected through a load-bearing component node 3 and a limit node, the load-bearing component node 3 includes a load-bearing support 31 embedded and fixed in the main structure 2, a support assembly 32 installed on the load-bearing support 31, and a first embedded assembly 33 arranged on the exterior wall panel 1, and the top of the support assembly 32 is welded and fixed to the first embedded assembly 33; the limit node includes an upper limit node 4 and a limit support node 5, the upper limit node 4 is used to connect the upper end of the exterior wall panel 1 with the main structure 2, and the limit support node 5 is used to connect the lower end of the exterior wall panel 1 with the main structure 2.

[0027] Specifically, by setting limit nodes, including an upper limit node 4 and a limit support node 5, the upper limit node 4 connects the upper end of the external wall panel 1 to the main structure 2, and the limit support node 5 connects the lower end of the external wall panel 1 to the main structure 2. This effectively limits the displacement of the external wall panel 1 under external forces such as wind and earthquake. The upper limit node 4 tightly connects the upper end of the external wall panel 1 to the main structure 2, while the limit support node 5 is responsible for fixing the lower end of the wall panel. The two work together to form a stable constraint system, greatly reducing the relative displacement of the wall panel under wind and earthquake. Secondly, the load-bearing component node 3 adopts a combination design of a load-bearing support 31 embedded and fixed in the main structure 2, a supporting component 32 installed on the load-bearing support 31, and a first embedded component 33 on the external wall panel 1. This not only increases the contact area of ​​the connection node and improves the stability of the connection, but also enhances the rigidity and bearing capacity of the node through welding and fixation; even under extreme conditions such as wind and earthquake, it can ensure that the connection node will not be damaged due to excessive force, which can reduce the overall shaking and deformation of the building and protect the safety of the building structure and internal facilities.

[0028] See also Figure 3 As shown, the support assembly 32 includes a support bolt 321 and an adjusting nut 322 disposed on the support bolt 321. The support bolt 321 is disposed on the hanging end of the load-bearing support 31. The adjusting nut 322 is threadedly connected to the support bolt 321, and the adjusting nut 322 is fixed to the load-bearing support 31 by welding. Specifically, the adjusting nut 322 is fixed to the load-bearing support 31 by welding, which ensures that the adjusting nut 322 will not loosen or fall off during the load-bearing process, thereby enhancing the stability and reliability of the entire support assembly 32.

[0029] See also Figure 1 As shown, the first embedded component 33 includes a plurality of embedded steel bars 331 embedded in the external wall panel 1 and a steel plate 332 connected to the plurality of embedded steel bars 331. The top surface of the supporting bolt 321 is welded and fixed to the lower end surface of the steel plate 332. Specifically, by embedding a plurality of steel bars in the external wall panel 1 and connecting them to the steel plate 332, a stable internal skeleton is formed. The top surface of the supporting bolt 321 is welded and fixed to the lower end surface of the steel plate 332. This connection method is not only firm and reliable, but also can effectively transfer loads, ensuring that there will be no relative displacement or loosening between the supporting bolt 321 and the steel plate 332. This further improves the connection stability between the external wall panel 1 and the main structure 2, and significantly improves the ability of the external wall panel 1 to resist external forces (such as wind pressure, earthquake force, etc.), thereby enhancing the safety of the overall building structure.

Specifically, the second embedded component 41 includes a plurality of embedded steel parts 411 embedded in the main structure 2 and a connecting steel block 412 connected to the plurality of embedded steel parts 411. The connecting steel block 412 is provided with a first mounting hole, and the connecting steel plate 43 is provided with a second mounting hole and a third mounting hole. The first mounting hole and the second mounting hole are correspondingly provided for the insertion of a first bolt 44 therethrough, and the third mounting hole is provided for the insertion of the steel column 42. This design significantly enhances the connection strength between the main structure 2 and the external wall panel 1 through the secure connection between the second embedded component 41 embedded in the main structure 2 and the steel column 42 in the external wall panel 1, thereby improving the stability and safety of the entire building structure, effectively resisting external forces such as wind loads and earthquakes, and reducing structural deformation. Secondly, the provision of the second embedded component 41 makes on-site installation convenient and quick, reduces the workload of on-site welding or drilling, and reduces construction difficulty and cost.

[0031] Preferably, the first mounting hole and the second mounting hole are both waist-shaped holes. Specifically, the design of the waist-shaped holes allows a certain range of lateral movement when installing the bolts, thereby facilitating the alignment of the holes and the insertion of the bolts, reducing the difficulty of installation and improving construction efficiency.

[0032] Preferably, the connecting steel sheet 43 includes a first steel sheet 431 and a second steel sheet 432 . The first steel sheet 431 and the second steel sheet 432 are perpendicular to each other.
