Description

Technical Field

[0001] The present invention relates to a wall structure for building houses, and more specifically, to a multi-section stacked thermal insulation building wall structure. Background Art

[0002] With the development of science and technology, people's requirements for the comfort of the living environment are gradually increasing. In cold weather conditions, it is necessary to improve the thermal insulation performance of building walls to prevent the loss of heat in the room. Moreover, the improvement of the thermal insulation effect of building walls reduces the usage of air conditioners in effect and enhances the effect of environmental protection and energy conservation. Currently, existing thermal insulation building walls and floor slabs are usually processed and produced from raw materials with relatively large thermal conductivity, such as clay, stones, steel bars, etc., which are not conducive to thermal insulation. Therefore, in some areas, a method of directly pasting thermal insulation boards on the outer side of the wall with relatively large thermal conductivity is adopted for thermal insulation. However, this method has poor aesthetics. And after the thermal insulation board is bonded to the wall, it is prone to falling off due to the influence of the external weather, is not suitable for long-term use, and has a relatively high later maintenance cost, reducing the service life and affecting the thermal insulation effect of the thermal insulation layer.

[0003] Furthermore, some walls on the market enhance the thermal insulation effect of the wall by filling a thermal insulation layer inside it. However, after the wall is installed, the thermal insulation structure inside the wall remains fixed in the wall and cannot achieve dynamic adjustment of the thermal insulation structure, resulting in the opposite effect. For example, when the designed wall has good thermal insulation performance, its heat dissipation performance is poor in a relatively high-temperature environment, leading to a hot indoor environment and a poor living experience for users. On the contrary, when the designed wall has good thermal conductivity, the heat inside the room will quickly escape at night, resulting in a cold indoor environment. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a multi-section stacked thermal insulation building wall structure with good thermal insulation effect, high practicability, convenient installation, and capable of dynamically adjusting inside the wall within a certain range.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A multi-section stacked thermal insulation building wall structure, including an installation base, and a plurality of thermal insulation units are sequentially stacked on the installation base to form a plurality of longitudinal thermal insulation components;

[0006] The thermal insulation unit includes an inner heat insulation plate and an outer heat insulation plate arranged inside and outside. A support keel is provided between the inner heat insulation plate and the outer heat insulation plate. Connecting columns are arranged on the outer surface of the inner heat insulation plate, and elastic connectors are provided on the inner surface of the outer heat insulation plate. The outer heat insulation plate is movably connected to the connecting columns arranged on the inner heat insulation plate through the elastic connectors. A support frame is arranged outside the outer heat insulation plate. A first horizontal rotating shaft and a second vertical rotating shaft are arranged inside the outer heat insulation plate. The outer heat insulation plate is rotationally connected to the support frame through the first horizontal rotating shaft, and the outer heat insulation plate is rotationally connected to the support keel through the second vertical rotating shaft. The first horizontal rotating shaft and the second vertical rotating shaft are perpendicular to each other. The support keel of the thermal insulation unit located in the innermost side of the longitudinal thermal insulation assembly is fixedly connected to the installation base, and the support keels of the remaining thermal insulation units are fixedly arranged on the outer heat insulation plate of the adjacent thermal insulation unit on their inner sides.

[0007] The present invention is further arranged as follows: A displacement compensation mechanism is further provided inside the support frame. The displacement compensation mechanism is configured to adjust the horizontal displacement of the outer heat insulation plate relative to the inner heat insulation plate. A telescopic adjustment mechanism is arranged outside the support frame. The telescopic adjustment mechanism is used to control the telescopic movement of the support frame along the axial direction of the second vertical rotating shaft. A deformation buffer mechanism is arranged at the lower end of the outer heat insulation plate. The deformation buffer mechanism is used to absorb the thermal expansion and contraction deformation of the outer heat insulation plate around the first horizontal rotating shaft.

[0008] Preferably, the displacement compensation mechanism includes a bidirectional adjustment lead screw, a displacement compensation slider, and a guiding connecting rod. The displacement compensation slider is threadedly connected to the bidirectional adjustment lead screw. The bidirectional adjustment lead screw is horizontally arranged inside the support frame. A chute matching the movement path of the displacement compensation slider is arranged on the outer heat insulation plate. The guiding connecting rod includes a support rod and a connecting piece. The lower end of the support rod is hinged to the displacement compensation slider, and the upper end passes through the chute and is connected to the connecting piece. A collar is further arranged at the end of the connecting piece. A limiting shaft matching the collar is arranged on the connecting column of the inner heat insulation plate.

[0009] Preferably, the telescopic adjustment mechanism includes a main hydraulic cylinder, a telescopic rod, and a pressure control module. The main hydraulic cylinder is vertically arranged between adjacent support keels. The end of the telescopic piston rod is connected to the support frame through a universal adjustment block. The pressure control module includes a temperature sensor and an automatic compensation valve.

[0010] Preferably, among the multiple thermal insulation units, the telescopic adjustment mechanism of the thermal insulation unit arranged in the innermost side of the longitudinal thermal insulation assembly is fixed on the installation base, and the telescopic adjustment mechanisms of the remaining thermal insulation units are arranged in a staggered manner on the outer heat insulation plate of the adjacent thermal insulation unit on their inner sides.

[0011] Preferably, the deformation buffer mechanism includes a corrugated telescopic sheet, which is serpentinely distributed along the horizontal direction of the wall body, and both ends of the corrugated telescopic sheet are fixedly connected to the heat insulation outer plate and the support frame respectively.

[0012] The present invention is further configured that: an isolation belt is further provided between each adjacent heat preservation unit, the isolation belt includes a heat insulation core material, a reflective film sleeved outside the heat insulation core material, a dividing strip is further provided between the reflective film and the heat insulation core material, and sealant is applied to both ends of the isolation belt.

[0013] The present invention is further configured that: the heat insulation inner plate includes a concrete base layer, a foamed core material layer and an aerogel layer, an L-shaped interface is provided around the heat insulation inner plate, and heat preservation glue is provided in the interface.

[0014] By adopting the above technical solutions, the beneficial effects are as follows: 1. By arranging a plurality of heat preservation units to form several modular heat preservation units, the internal structure of the heat preservation wall body can be dynamically adjusted through adjustable mechanisms arranged in each heat preservation unit. At the same time, by arranging multiple layers of heat insulation boards in each heat preservation unit, the comprehensive heat preservation performance of the wall body is significantly improved. Moreover, the vertically stacked heat preservation units form a heat insulation barrier through their rigid connections with the support keels and the first / second vertical rotating shafts, achieving a more uniform heat preservation effect. And, a displacement compensation mechanism and a telescopic adjustment mechanism are provided in the heat insulation wall body structure, so that each heat preservation unit can dynamically compensate for displacement according to temperature changes, avoiding the problem of cracking caused by thermal expansion and contraction or structural deformation after long-term use of the wall body. At the same time, since the longitudinal heat preservation components in the wall body are formed by vertically stacking a plurality of heat preservation units, the heat preservation units can be brought to the site after being prefabricated in the factory. During the processing process, only each heat preservation unit needs to be stacked and assembled, which can significantly reduce the construction period, avoid manual processing and thus generate errors. And an isolation belt is provided between each adjacent heat preservation unit, and the isolation belt can further improve the sealing performance between the heat preservation units, reduce radiative heat transfer and air penetration, ensure the long-term stability of the overall structure, and improve the energy-saving efficiency.

[0015] 2. Further, a first horizontal rotating shaft and a second vertical rotating shaft are provided inside the heat-insulating outer plate. The heat-insulating outer plate realizes its multi-directional rotation ability through the first horizontal rotating shaft and the second vertical rotating shaft. At the same time, a displacement compensation mechanism is provided inside the support frame. The displacement compensation mechanism realizes the precise control of the horizontal displacement amount through the cooperation of a bidirectional adjusting lead screw, a displacement compensation slider and a guiding connecting rod. And the telescopic adjusting mechanism includes a main hydraulic cylinder, a telescopic rod and a pressure control module. The pressure control module includes a temperature sensor and an automatic compensation valve. Among them, the main hydraulic cylinder can dynamically adjust the support spacing of each longitudinal heat-insulating component according to the feedback temperature at the temperature sensor, so as to increase the distance between each adjacent longitudinal heat-insulating component, thereby releasing the thermal stress in the wall. The deformation buffering mechanism includes a wavy telescopic sheet, and the wavy telescopic sheet is distributed in a serpentine shape along the horizontal direction of the wall. The above design scheme can disperse local stress, absorb the deformation received by the heat-insulating unit, and maintain the flatness of the heat-insulating outer plate. At the same time, the above structure can enable the manufactured wall structure to adapt to the temperature change in a complex environment, significantly reduce the structural fatigue of the longitudinal heat-insulating component, and extend the service life of the overall structure. And each mechanism is tightly connected to ensure that the airtightness of the overall structure is maintained during the dynamic adjustment of the heat-insulating unit and has good heat-insulating performance during the adjustment process, avoiding the failure of the heat-insulating system structure.

[0016] 3. At the same time, the heat-insulating inner plate includes a concrete base layer, a foamed core material layer and an aerogel layer. The above structure can enable the heat-insulating inner plate to achieve the balance of high-efficiency heat insulation and structural strength within a limited thickness. At the same time, an isolation belt is provided between each adjacent heat-insulating unit. The isolation belt includes a heat-insulating core material, a reflective film sleeved outside the heat-insulating core material, and a dividing strip is also provided between the reflective film and the heat-insulating core material. Sealant is applied to both ends of the isolation belt. The dividing strip and the sealant are cooperatively arranged to strengthen the airtightness and waterproofness at the joint of the heat-insulating unit. An L-shaped interface is arranged around the heat-insulating plate, and heat-insulating glue is provided inside the interface, so that a sealing layer is provided inside the heat-insulating plate at the L-shaped interface, effectively blocking water vapor and forming a buffer for the heat-insulating unit to avoid the attenuation of the wall heat-insulating performance caused by joint cracking. As the preference of the above scheme, the materials of the heat-insulating unit can be selected as bio-based foamed core material and recyclable isolation belt core material, which can reduce the overall carbon emissions while improving the heat-insulating performance, meeting the development requirements of green buildings.

[0017] 4. Moreover, in this application, a temperature sensor is provided inside the thermal insulation unit. After detecting the temperature, the temperature sensor feeds back to the pressure control module, enabling each adjustment mechanism inside the thermal insulation unit to adaptively adjust the interior of the wall according to the temperature changes detected by the temperature sensor. Also, through the inclined stacking and staggered arrangement of the thermal insulation units, it can be conveniently applied to scenarios with non-uniform load distributions such as curved buildings, making the application range of the above-mentioned thermal insulation building wall wider. At the same time, with the disassembly and assembly design of the limit shaft - collar for a single thermal insulation unit, after a problem occurs in a single thermal insulation unit, only the current thermal insulation unit needs to be disassembled and replaced, so that the maintenance or replacement operation does not require damaging the overall structure, significantly reducing the maintenance cost. Preferably, the control system for controlling each adjustment mechanism in the structure of this application can be selectively docked with the Building Information Modeling (BIM) platform, and the operation and maintenance management of the wall is carried out through data-driven, providing an efficient and reliable solution for low-energy prefabricated buildings.
