Description

Technical Field

[0001] This utility model belongs to the technical field of external shear wall structure, and particularly relates to an external shear wall structure with integrated graphene thermal insulation template. Background Technology

[0002] An external shear wall structure is a building system that utilizes the building's exterior walls as the primary load-bearing and lateral force-resisting components. Reinforced concrete wall panels bear vertical gravity loads, horizontal wind loads, and seismic forces. Its structural height is typically the same as the overall building height, with a relatively thin thickness, resulting in extremely high in-plane lateral stiffness and effective control of structural lateral displacement. This system forms a load-bearing whole through walls and floor slabs, making it suitable for high-rise residential buildings, apartments, and other buildings with predominantly small spaces. It can be constructed to significantly greater heights than frame structures. Its advantages include high space utilization and no exposed beams or columns inside, but it also has disadvantages such as inflexible floor plan layout and limitations on large-space modifications.

[0003] The existing double-sided composite slab shear wall is constructed by first casting a composite slab with a steel reinforcement truss. One side of the steel reinforcement truss is exposed on one side of the composite slab, forming an exposed section of the steel reinforcement truss. Then, another composite slab is cast without a steel reinforcement truss. Before the concrete of the second composite slab solidifies, the exposed section of the steel reinforcement truss of the first composite slab is inserted into the second composite slab. After the second composite slab solidifies, the two composite slabs are connected. After the two composite slabs are connected, they are hoisted onto the floor slab, and the floor slab's reinforcing bars extend into the space between the two composite slabs. Finally, the hollow space between the two composite slabs is cast on-site.

[0004] Existing external shear wall structures have poor thermal insulation performance. When the insulation of the external shear wall is insufficient, indoor heat is rapidly lost through the wall, causing the heating system to operate at a high load continuously, resulting in a significant increase in energy consumption. In high-temperature environments, heat transfer through the wall causes indoor temperatures to rise, requiring the air conditioning system to operate for longer periods to maintain a comfortable environment, further increasing electricity consumption. To solve these problems, it is necessary to design an external shear wall structure integrating graphene insulation templates. Utility Model Content

[0005] This invention provides an external shear wall structure with integrated graphene thermal insulation template to solve the above-mentioned problems in the prior art.

[0006] This utility model is implemented as follows: an external shear wall structure with integrated graphene thermal insulation template, comprising two stacked shear wall units. Each shear wall unit includes, from the outside to the inside, a finishing layer, a plastering layer, an integrated graphene thermal insulation template, and a cast-in-place concrete layer. An alkali-resistant mesh is embedded in the plastering layer. The integrated graphene thermal insulation template is connected and fixed to the plastering layer and the cast-in-place concrete layer by special anchor bolts. The other end of the special anchor bolts is anchored in the cast-in-place concrete layer to achieve overall fixation of each layer.

[0007] The integrated graphene insulation template has a honeycomb structure to enhance its thermal insulation performance; the finishing layer is an exterior wall decorative layer, and the plastering layer is a cement-based plastering layer; the integrated graphene insulation template is made of graphene composite material.

[0008] Preferably, the two shear wall units are precast composite slab structures. One side of the reinforcing steel truss of each shear wall unit is exposed from one side of the shear wall unit, forming an exposed section of the reinforcing steel truss. The two shear wall units are arranged opposite each other, with the exposed sections of the reinforcing steel truss of the two shear wall units located on their facing surfaces. In the horizontal plane, the exposed sections of the reinforcing steel truss on the two shear wall units are staggered.

[0009] Preferably, grooves are provided on opposite sides of both shear wall units, and a support is provided at each groove. One end of the support is inserted into the groove, and the support is inserted into the interior of multiple exposed sections of the reinforcing steel truss and fits against the exposed sections of the reinforcing steel truss.

[0010] Preferably, multiple sets of spaced-apart connecting components are provided between the two shear wall units, and the two shear wall units are connected by the connecting components.

[0011] Preferably, the connecting assembly includes grooves formed on opposite sides of the two shear wall units, each groove having a first threaded sleeve fixedly installed therein, and a second threaded sleeve provided between the two shear wall units. Each end of the second threaded sleeve has a movable screw inserted into it, one end of which is threadedly connected to the second threaded sleeve, and the other end of which is inserted into and threadedly connected to the first threaded sleeve.

[0012] Compared with related technologies, the external shear wall structure of the integrated graphene thermal insulation template provided by this utility model has the following beneficial effects:

[0013] Integrated graphene insulation panels are made of graphene composite materials with a honeycomb structure. Graphene has excellent thermal conductivity, and the insulation panels made from its composite materials effectively block heat transfer. The honeycomb structure further enhances the thermal insulation performance, reducing heat loss from the interior to the exterior through the walls during heating, and also reducing the conduction of high outdoor temperatures into the interior through the walls in high-temperature environments. Thus, during heating, indoor heat does not dissipate quickly, and the heating system does not need to operate at a continuously high load; in high-temperature environments, outdoor heat does not easily enter the interior, and the air conditioning system does not need to run for longer periods to maintain a comfortable environment, thereby reducing energy consumption and electricity usage.

[0014] The wall structure is composed of a finishing layer, a plastering layer, an integrated graphene insulation template, and a cast-in-place concrete layer, arranged sequentially from the outside in. The finishing layer serves as the exterior wall decoration, primarily providing aesthetics and protection. The plastering layer is a cement-based plastering layer with embedded alkali-resistant mesh fabric, enhancing its strength and crack resistance. The integrated graphene insulation template is responsible for the main thermal insulation. The cast-in-place concrete layer provides structural support. These layers work together to ensure both the structural performance of the wall and excellent thermal insulation.

[0015] By tightly integrating the insulation layer with the cast-in-place structure, a "structure and insulation integration" system is formed. This not only eliminates the interface thermal resistance and bonding risks between the traditional insulation layer and the structural layer, but also utilizes the pressure of the cast-in-place concrete to create a mechanical bond between the insulation material and the structural layer, improving the overall integrity of the system, reducing the risk of later detachment, and achieving efficient integration of building structure and insulation function.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] A preferred embodiment of the external shear wall structure of the integrated graphene thermal insulation template provided by this utility model is, for example... Figures 1 to 4 As shown:

[0024] An external shear wall structure with integrated graphene thermal insulation template includes two stacked shear wall units 1. The shear wall unit 1 includes a finishing layer 104, a plastering layer 103, an integrated graphene thermal insulation template 102, and a cast-in-place concrete layer 101 arranged sequentially from the outside to the inside. An alkali-resistant mesh is embedded in the plastering layer 103. The integrated graphene thermal insulation template 102 is connected and fixed to the plastering layer 103 and the cast-in-place concrete layer 101 by special anchor bolts 105. The other end of the special anchor bolts 105 is anchored in the cast-in-place concrete layer 101 to achieve overall fixation of each layer.

[0025] The integrated graphene insulation template 102 has a honeycomb structure to enhance its thermal insulation performance; the finishing layer 104 is the exterior wall decorative layer, and the plastering layer 103 is a cement-based plastering layer; the integrated graphene insulation template 102 is made of graphene composite material.

[0026] The two shear wall units 1 are precast composite slab structures. One side of the steel reinforcement truss of the shear wall unit 1 is exposed from one side of the shear wall unit 1, forming an exposed section 2 of the steel reinforcement truss. The two shear wall units 1 are arranged opposite each other, and the exposed sections 2 of the steel reinforcement truss of the two shear wall units 1 are located on their facing surfaces. In the horizontal plane, the exposed sections 2 of the steel reinforcement truss on the two shear wall units 1 are staggered.

[0027] Both shear wall units 1 have grooves 3 on opposite sides, and each groove 3 has a support 4. One end of the support 4 is inserted into the groove 3, and the support 4 is inserted into the interior of multiple exposed sections 2 of the steel truss and fits against the exposed sections 2 of the steel truss.

[0028] Multiple sets of spaced connecting components are provided between the two shear wall units 1, and the two shear wall units 1 are connected by the connecting components.

[0029] The connecting assembly includes grooves 5 formed on opposite sides of two shear wall units 1. A first threaded sleeve 6 is fixedly installed in each groove 5. A second threaded sleeve 7 is provided between the two shear wall units 1. Movable screws 8 are inserted into both ends of the second threaded sleeve 7. One end of the movable screw 8 is threadedly connected to the second threaded sleeve 7, and the other end of the movable screw 8 is inserted into the first threaded sleeve 6 and threadedly connected to the first threaded sleeve 6.

[0030] The integrated graphene insulation template 102 is made of graphene composite material with a honeycomb structure. Graphene has excellent thermal conductivity, and the insulation template made of its composite material can effectively block heat transfer. The honeycomb structure further enhances the thermal insulation performance, reducing the loss of indoor heat to the outside through the walls during heating, and also reducing the conduction of outdoor high temperature to the inside through the walls in high-temperature environments. Thus, during heating, indoor heat is not easily lost quickly, and the heating system does not need to operate at a continuous high load; in high-temperature environments, outdoor heat is not easily transferred into the room, and the air conditioning system does not need to run for longer periods to maintain a comfortable environment, thereby reducing energy consumption and electricity usage.

[0031] The wall structure is composed of a finishing layer 104, a plastering layer 103, an integrated graphene insulation template 102, and a cast-in-place concrete layer 101, arranged sequentially from the outside in. The finishing layer 104 serves as the exterior wall decoration layer, primarily providing decoration and protection; the plastering layer 103 is a cement-based plastering layer with embedded alkali-resistant mesh fabric, enhancing its strength and crack resistance; the integrated graphene insulation template 102 is responsible for the main thermal insulation; and the cast-in-place concrete layer 101 provides structural support. The layers work together to ensure both the structural performance of the wall and excellent thermal insulation.

[0032] The two shear wall units 1 are precast composite slab structures, with one side of the reinforcing steel truss exposed, forming exposed section 2. The two shear wall units 1 are positioned opposite each other, with the exposed section 2 located on opposite faces and staggered in the horizontal plane. Concrete is subsequently poured between the two shear wall units 1, and the staggered exposed section 2 enhances the strength of the cast-in-place concrete. Support members 4 provide support for the exposed section 2, further improving the strength of both the exposed section 2 and the cast-in-place concrete.

[0033] One end of the movable screw 8 is threadedly connected to the second threaded sleeve 7, and the other end is inserted into and threadedly connected to the first threaded sleeve 6. By rotating the movable screws 8 on both sides, their positions within the first threaded sleeve 6 and the second threaded sleeve 7 can be adjusted, thereby adjusting the spacing between the two shear wall units 1. At the same time, the connecting assembly is used to improve the tight connection and fixation between the two shear wall units 1, ensuring the structural stability of the wall in the horizontal and other directions.

[0034] By tightly integrating the insulation layer with the cast-in-place structure, a "structure and insulation integration" system is formed. This not only eliminates the interface thermal resistance and bonding risks between the traditional insulation layer and the structural layer, but also utilizes the pressure of the cast-in-place concrete to create a mechanical bond between the insulation material and the structural layer, improving the overall integrity of the system, reducing the risk of later detachment, and achieving efficient integration of building structure and insulation function.
