Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a wall panel connection node structure and a wall panel having the same structure. Background Technology
[0002] In recent years, with the increasing severity of global climate change and the energy crisis, building energy conservation and emission reduction have become a global research hotspot. Among them, zero-energy buildings, as an important development direction in the field of building energy conservation, have enormous potential and value. Zero-energy buildings can significantly improve the thermal insulation performance of buildings and reduce the energy consumption of air conditioning systems by reducing the heat transfer coefficient of external walls, thereby achieving the goal of energy conservation and emission reduction.
[0003] However, when using UHPC (Ultra-High Performance Concrete) composite wall panels with integrated insulation and structure, if the internal metal connectors and steel framing are not properly handled during design or construction, these metal components can form "thermal bridges." A thermal bridge refers to a situation in a building envelope where certain materials or structures have higher thermal conductivity than surrounding materials, allowing heat to pass through these parts more easily and resulting in additional heat loss. This thermal bridge phenomenon leads to significant localized heat dissipation, increasing the heat transfer coefficient of the UHPC wall panel and consequently increasing building energy consumption, making it difficult to achieve the energy-saving and emission-reduction design goals required for zero-energy buildings. Utility Model Content
[0004] The purpose of this utility model is to provide a wall panel connection node structure and a wall panel having the same structure, so as to solve one or more problems in the prior art, such as the thermal bridging problem that easily occurs in the metal components inside the wall panel, which increases building energy consumption.

[0010] Optionally, the first hanger is fixedly connected to a sleeve embedded in the prefabricated panel by connecting bolts.

[0025] Example 1
[0026] This embodiment provides a wall panel connection node structure. Specifically, please refer to... Figure 1 , Figure 1 This is a specific example diagram of the wall panel connection node construction provided in this embodiment. From Figure 1 As can be seen, the wall panel connection node structure includes a prefabricated panel 10 and a plurality of horizontal keels 11 distributed along the length extension direction of the prefabricated panel 10 on one side of the prefabricated panel 10. Each horizontal keel 11 is connected to the prefabricated panel 10 through a connecting component 12, and a heat insulation component 13 is provided between each connecting component 12 and the horizontal keel 11. Therefore, the wall panel connection node structure provided in this embodiment, by connecting each horizontal keel 11 to the prefabricated panel 10 through a connecting component 12, can improve the connection effect and reliability between the prefabricated panel 10 and the horizontal keels 11. Furthermore, by providing a heat insulation component 13 between each connecting component 12 and the horizontal keel 11, the thermal bridging effect between the connecting component 12 and the horizontal keel 11 can be reduced, reducing heat loss through the connecting component 12, thereby improving the thermal performance of the wall panel and reducing building energy consumption, laying a good foundation for achieving the design goal of zero-energy building energy conservation and emission reduction.
[0027] It should be noted that, as those skilled in the art will understand, the present invention does not impose excessive limitations on the type of the connecting component 12.
[0028] Exemplary, in some exemplary embodiments, the connecting assembly 12 includes a first connector 121 connected to the transverse keel 11 along its length extension direction, and a plurality of hanger groups 122 connected to the first connector 121 and distributed along its length extension direction; the hanger groups 122 are configured to allow the prefabricated panel 10 to be hung onto the first connector 121; the heat insulation assembly 13 is provided between the first connector 121 and the transverse keel 11. Thus, by connecting the first connector 121 to the transverse keel 11, the prefabricated panel 10 can be more securely connected to the transverse keel 11. By distributing the plurality of hanger groups 122 along the length extension direction of the first connector 121, the connection stability between the prefabricated panel 10 and the transverse keel 11 can be further improved. The hanger groups 122 allow the prefabricated panel 10 to be hung onto the first connector 121, thereby facilitating the installation and removal of the prefabricated panel 10 and improving construction efficiency. By providing a heat insulation component 13 between the first connector 121 and the transverse keel 11, the first connector 121 can be separated from the transverse keel 11, thereby effectively reducing the thermal bridging effect between the connector 121 and the transverse keel 11.
[0029] It should be noted that the present invention does not impose excessive limitations on the number and distribution of the hanging accessory groups 122. Exemplarily, in some exemplary embodiments, at least four hanging accessory groups 122 are evenly distributed along the length extension direction of the first connector 121.
[0030] For example, please continue to see Figure 1 and Figure 2 ,in, Figure 2 This is a specific example diagram illustrating the connection between the connecting component 12 and the prefabricated panel 10 and the transverse keel 11 provided in this embodiment. From... Figure 1 and Figure 2 As can be seen, the first connector 121 includes an angle steel 1211, which has a first side 12111 and a second side 12112 that are perpendicular to each other. The first side 12111 is fixedly connected to the transverse keel 11 by a first fastener 123, and the heat insulation component 13 is provided between the first side 12111 and the transverse keel 11. The second side 12112 is fixedly connected to the hanging assembly 122 by a second fastener 124. Thus, by connecting the angle steel 1211 to the transverse keel 11, the angle steel 1211 has high strength and rigidity, and can withstand large vertical and horizontal loads, thereby enhancing the stability of the structure.
[0031] It should be noted that, as those skilled in the art will understand, the first fastener 123 and the second fastener 124 may be, but are not limited to, bolts and nuts that match the bolts.
[0032] It should be noted that the above description is merely an exemplary illustration of the first connector 121 and not a limitation thereof. This utility model does not impose excessive limitations on the specific type of the first connector 121; for example, in some other embodiments, the first connector 121 may also be a square steel bar.
[0033] For the preferred options, please continue reading. Figure 2 ,like Figure 2 As shown, each of the mounting brackets 122 includes a first mounting bracket 1221 fixedly connected to the prefabricated panel 10 and a second mounting bracket 1222 fixedly connected to the first connector 121. The first mounting bracket 1221 is attached to the second mounting bracket 1222. Thus, through the cooperative use of the first mounting bracket 1221 and the second mounting bracket 1222, the prefabricated panel 10 can be attached to the first connector 121, thereby laying the foundation for the rapid installation and removal of the prefabricated panel 10.
[0034] It should be noted that this utility model does not impose excessive limitations on the specific shapes of the first pendant 1221 and the second pendant 1222. For example, please refer to [reference needed]. Figure 2 ,like Figure 2 As shown, the first hanging member 1221 and the second hanging member 1222 can be U-shaped aluminum alloy hanging members. The open end of the first hanging member 1221 and the open end of the second hanging member 1222 are opposite to each other. The closed end of the first hanging member 1221 is fixedly connected to the prefabricated panel 10, and the closed end of the second hanging member 1222 is fixedly connected to the first connecting member 121.
[0035] Furthermore, the top of the first hanger 1221 is threaded with an adjusting bolt 1223, the bottom of which abuts against the top of the second hanger 1222. Thus, by threading the adjusting bolt 1223 onto the top of the first hanger 1221 and abutting the bottom of the adjusting bolt 1223 against the top of the second hanger 1222, tightening the adjusting bolt 1223 allows the prefabricated panel 10 to move vertically upwards, and loosening the adjusting bolt 1223 allows the prefabricated panel 10 to move vertically downwards. This allows for fine-tuning of the vertical height of the prefabricated panel 10, laying a good foundation for ensuring alignment of each prefabricated panel 10 during wall panel assembly.
[0036] Preferably, the first hanger 1221 is fixedly connected to the sleeve 1225 embedded in the prefabricated panel 10 by a connecting bolt 1224. Thus, the prefabricated panel 10 and the first hanger 1221 can be fixed by the cooperation of the connecting bolt 1224 and the sleeve 1225, which makes it easier to connect or disassemble the prefabricated panel 10 and the first hanger 1221.
[0037] For example, in some embodiments, the sleeve 1225 may be an M10 stainless steel sleeve.
[0038] It should be noted that the above is merely an exemplary description of the connecting component 12, and not a limitation of this utility model. Furthermore, this utility model does not impose excessive restrictions on the type of the transverse keel 11. Exemplarily, in some embodiments, the transverse keel 11 can be a square steel structure; in other embodiments, the transverse keel can also be an angle steel structure.
[0039] For example, please see Figure 3 , Figure 3 This is another specific example diagram showing the connection of the connecting component 12 provided in this embodiment to the prefabricated panel 10 and the transverse keel 11. From Figure 3 It can be seen that the connecting component 12 may also include a plurality of T-shaped hangers 125 that are fixedly connected to the transverse keel 11 by bolts (not shown in the figure) along the length extension direction of the transverse keel 11. Each T-shaped hanger 125 is snapped into a groove (not shown in the figure) opened on the prefabricated panel 10, and the heat insulation component 13 is provided between each T-shaped hanger 125 and the transverse keel 11.
[0040] Preferably, the thermal insulation component 13 includes a polyurethane pad. Therefore, by using the polyurethane pad, which has excellent thermal insulation properties, heat transfer can be effectively blocked. In addition, the polyurethane pad has high strength, can withstand large loads and pressures, and is not easily damaged.
[0041] Furthermore, the prefabricated panel 10 includes a UHPC decorative panel, the area of which is not less than 10 square meters.
[0042] It should be noted that the present invention does not impose excessive limitations on the size of the prefabricated panel 10. For example, in some embodiments, the length of the UHPC decorative panel can be 5 meters and the width can be 2 meters; in other embodiments, the length of the UHPC decorative panel can be 4 meters and the width can be 2.5 meters.
[0043] It should be noted that the above description is merely an exemplary illustration of the precast panel 10 and not a limitation thereof. Exemplarily, in some other embodiments, the precast panel 10 may also be a precast concrete slab.
[0044] Preferably, the length of the horizontal keel 11 is the same as the width of the prefabricated panel 10. Therefore, when assembling the wall panels, by ensuring that the length of the horizontal keel 11 is the same as the width of the prefabricated panel 10, gaps between the prefabricated panels 10 and between the horizontal keels 11 can be avoided, thereby improving both the appearance quality of the building and the structural safety.

Each horizontal keel is connected to the prefabricated panel through a connecting component, and a heat insulation component is provided between each connecting component and the horizontal keel.
