Description

Technical Field

[0001] The utility model belongs to the technical field of assembled buildings, and in particular relates to an assembled light composite thermal insulation exterior wall panel system. Background Art

[0002] In modern buildings, the application of thermal insulation materials has become more and more common, especially in the thermal insulation protection of the building periphery. By using thermal insulation materials, the thickness of the building periphery structure can be effectively reduced, thereby increasing the indoor usable area.

[0003] However, the mainstream insulation materials on the market are mainly divided into two categories: organic combustible materials and inorganic non-combustible materials. Organic combustible materials, such as EPS (polystyrene), XPS (extruded polystyrene) and PU (polyurethane), have low thermal conductivity, so they have good energy-saving effects and their system applications are relatively mature. However, these materials have poor safety performance. Once a fire occurs, a large amount of smoke and toxic gases will be produced during combustion, posing a serious threat to personnel safety. On the other hand, inorganic insulation materials, such as rock wool, glass wool and perlite, are all Class A non-combustible materials with high safety. However, these materials have poor thermal insulation performance, high water absorption, high density, and high cost, so they are difficult to promote.

[0004] In recent years, due to the increasing number of fire incidents caused by thermal insulation materials, relevant departments have issued a series of documents to strictly regulate the performance of thermal insulation materials. Therefore, how to provide a composite thermal insulation exterior wall panel with both good thermal insulation performance and strong fire resistance has become a problem that needs to be solved urgently by technicians in this field. Utility Model Content

[0005] In order to solve the above problems existing in the prior art, an assembled light composite thermal insulation exterior wall panel system is provided.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0017] 1. In the utility model, an inner layer is provided with an insulation core, which is positioned by a limit frame, and an outer layer of the insulation core is coated with insulation slurry.

[0027] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments.

When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0030] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] like Figure 1-3 As shown, this embodiment proposes an assembled lightweight composite thermal insulation exterior wall panel system, which includes:

[0033] Insulation inner core 3; in some embodiments, the insulation inner core 3 is glass fiber reinforced polyurethane, and the insulation inner core 3 is a rectangular parallelepiped structure;

[0034] Limiting frames 2, which are arranged on both sides of the thermal insulation core 3, and the two limiting frames are connected by limiting rods 4; the limiting frames 2 are used to cover and position the thermal insulation core 3, so as to prevent the thermal insulation core 3 from being displaced during subsequent construction;

[0035] Thermal insulation slurry 5 is used to wrap the limiter. Thermal insulation slurry 5 is a Class B material, composed of a variety of inorganic and organic components, has good thermal insulation performance, and can reduce indoor energy consumption to a certain extent.

[0036] Concrete slurry 1 is used to wrap the thermal insulation slurry 5. Concrete slurry 1 is generally considered to be a Class A material, which will not burn even at high temperatures. It is used to protect the thermal insulation core 3 and the thermal insulation slurry 5 inside it to prevent them from directly contacting a fire source and burning.

[0037] In this solution, a limiting frame 2 is set outside the insulation core and the insulation slurry 5 is poured. The combination of the two insulation materials can effectively isolate the external temperature and reduce heat loss, thereby improving the overall insulation effect. Furthermore, the limiting frame 2 plays a supporting role while covering and positioning the insulation inner core 3, making the formed insulation exterior wall panel system more stable.

[0038] In some embodiments, the limiting frame 2 is a thin-walled steel or glass fiber reinforced plastic, and the thermal insulation core is wrapped and positioned by the limiting frame 2 to prevent the thermal insulation core 3 from shifting during the pouring of the thermal insulation slurry 5. In order to further improve the wrapping performance on both sides of the limiting frame 2, in some embodiments, the limiting frame 2 is a U-shaped structure, which can further protect the side of the thermal insulation core 3 from being damaged by external forces and can further position the thermal insulation core.

[0039] In some embodiments, the limit rods 4 are cross-arranged on both sides of the insulation core 3 for connecting the two limit frames 2. The limit rods 4 are used to connect the limit frames 2 on both sides. When the insulation slurry 5 is poured, it is further in contact with the insulation core 3 and the limit frames 2, so that the combination of the three is closer to form a whole, thereby enhancing the strength of the three after the combination, and can further increase the insulation performance.

[0040] Embodiment 2

[0041] like Figure 4-5 As shown, this embodiment proposes an assembled light composite thermal insulation exterior wall panel system, and other structures are the same as those of the first embodiment. The only difference is that in this embodiment, the limit frame 2 is formed by combining a plurality of frame units 21, and a plug block 22 is provided at the bottom of the frame unit 21, and a socket 23 adapted to the plug frame is provided at the top of the frame unit 21.

[0042] Taking into account that in actual applications, the length of the insulation core 3 is not fixed, during the design process, the insulation core 3 of a suitable length is selected according to the current building environment; based on this, a structure that can adjust the height of the limit frame 2 is designed. After determining the length of the insulation core 3, several groups of frame units 21 are selected and plugged in to completely wrap the insulation material inside. A small amount of excess part can be appropriately cut off to achieve the suitability of the insulation core 3 of different lengths.

[0043] In some embodiments, the limiting rods 4 are arranged in a cross shape between the two frame units 21 to wrap the thermal insulation core 3 and position it, so as to prevent the thermal insulation core 3 from shifting during subsequent construction.

[0044] In some embodiments, the corners of the molded concrete slurry 1 are provided with a recessed accommodating cavity 6. When adjacent molded concrete slurries 1 are spliced, the accommodating cavities 6 are combined to form a joint 7 for leveling. In the present embodiment, the joint 7 is semicircular. The close-jointed joint treatment is convenient for construction. During the construction process, the slurry in the joint 7 can play a role in filling the gap of the joint 7. After a period of concrete pouring, most of the concrete shrinkage has been completed. At this time, modified polymer cement mortar is used for leveling. The joint treated in this way will have no cracks in the later stage, which greatly improves the overall strength and quality.

[0045] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
