Description

A kind of insulation brick

technical field

The utility model relates to the field of building materials, in particular to a thermal insulation brick.

Background technique

Bricks are one of the essential building materials in the field of construction and one of the most basic structural components in house construction.

Insulation brick is a kind of brick (in fact, all bricks have the function of heat preservation, but the strength of heat preservation function is different), the house built with heat preservation brick has better heat preservation performance, heat preservation brick is especially suitable for our country In the northern region, insulation bricks with better thermal insulation performance have been in short supply in the market.

The common insulation bricks on the market are holes in the bricks or insulation layers. Generally speaking, the structure is relatively simple, and the insulation effect is average. It is suitable for buildings that do not require very high insulation performance.

Some buildings have very high requirements on the thermal insulation performance of the house. The construction of this kind of house not only needs to start with the structure of the wall, but also needs to use bricks with higher thermal insulation performance. But bricks in the prior art obviously cannot satisfy its demand.

Utility model content

The utility model provides a thermal insulation brick, aiming at solving the above problems.

The utility model is achieved in that:

Insulation bricks, including two porous bricks, the porous bricks are cuboid structure, the two porous bricks are connected through the insulation layer, the largest surface of each porous brick is connected with the insulation layer, and the insulation layer is made of insulation material; the porous brick A plurality of thermal insulation holes are vertically spaced on the brick, and the outline of the thermal insulation holes in the cross section of the porous brick includes a wavy outline.

There are two porous bricks inside the heat insulating brick, and the two porous bricks are connected through the heat insulating layer. The thermal insulation layer is located between the porous bricks. For the walls made of this thermal insulation brick, one of the porous bricks is close to the interior, and the other is close to the exterior. In winter, after the indoor heat is transferred to the insulation layer through the indoor porous bricks, most of the heat preservation effect of the insulation layer is no longer transferred, so that the heat remains indoors; in summer, the outdoor heat is transferred to the insulation layer through the outdoor porous bricks. , Most of the thermal insulation effect of the thermal insulation layer will no longer continue to pass inward, so that the room remains cool.

There are three basic ways of heat transfer: heat conduction, convective heat transfer and radiation heat transfer. Heat conduction relies on the movement or (and) vibration of molecules, atoms or electrons of substances to transfer heat, and heat conduction in fluids is similar to molecular momentum transfer. Convective heat transfer relies on the macroscopic movement of fluid microgroups to transfer heat, so it can only exist in fluids and is accompanied by momentum transfer. Radiation heat transfer is the transfer of heat through electromagnetic waves without the need for a medium.

The porous brick has a porous structure. After the heat is transferred to the wall of the insulation hole by a certain or concentrated transfer method, it can only be further transferred in the form of heat radiation, and the heat transfer method of heat radiation is compared with the other two groups of heat transfer methods. The form is relatively slow, so the porous brick with porous structure can greatly reduce heat transfer and achieve better insulation effect.

At the same time, the outline of the thermal insulation hole in the cross section of the porous brick includes a wavy outline. The wavy surface forms a reflective surface. When the heat is transferred to the reflective surface in the form of thermal radiation, due to the special structure of the reflective surface, the amplitude of the thermal radiation is reduced, and the heat transferred through the thermal radiation is significantly slowed down, which further reduces the heat transfer and further improves the thermal insulation performance.

Therefore, the thermal insulation brick structure of this structure is ingeniously designed and has a variety of thermal insulation designs. The thermal insulation wall made of this thermal insulation brick has a good thermal insulation effect, which makes the thermal insulation effect of the house better, especially suitable for areas with very cold weather. , to meet the needs of the house for thermal insulation performance.

Further, the heat preservation hole is circular, and the outline of the heat preservation hole is a wavy circle in the cross section of the porous brick.

As shown in Figure 1, the heat preservation hole can be circular, and when the heat preservation hole is circular, its entire outline can be wavy. The circular heat preservation hole is more convenient to manufacture, and it is convenient to pass through the pipeline.

The heat preservation hole can also be a rectangular hole, and one of the inner walls of the heat preservation hole is a corrugated surface. As shown in Fig. 2, the rectangular heat preservation hole can occupy a larger area, so that the range of the heat preservation hole is larger. Only one inner wall in the rectangular heat preservation hole is a wave surface, and this design can also achieve the purpose of heat preservation.

Further, the wavy surface of the thermal insulation hole is close to the thermal insulation layer. The heat is transferred from the indoor to the outdoor, and the wave surface set at this position can play a better reflection effect and reduce the heat radiation effect.

Further, the heat preservation hole is a rectangular hole, and all inner walls of the heat preservation hole are wavy surfaces. As shown in Figure 4, the insulation brick with this structure has better insulation effect and is more high-grade.

Further, the thickness of one of the porous bricks is 2cm-4cm thicker than that of the other porous brick. The main function of this kind of insulation brick is to reduce the loss of indoor heat in cold seasons. Among them, the thicker porous brick is set near the indoor position, and the other porous brick is set close to the outdoor position. The thermal insulation brick in this way can further improve the thermal insulation effect.

Further, it can also be designed like this: the side where the porous brick is connected to the insulation layer is the connection surface, and the connection surface is provided with T-shaped card slots along the vertical direction, and T-shaped card slots are provided on both sides of the insulation layer. block, two porous bricks and the insulation layer are clamped together through the clamping block and the clamping groove.

The material of the porous brick and the insulation layer is different, so they are processed separately during processing, and then connected together after processing. The porous bricks and the insulation layer of the above structure are connected by clamping, which is convenient in connection and ingenious in structure, and does not need to use other adhesives or other auxiliary tools and materials during connection, and the connection efficiency is high and the cost is low.

Insulation can be made of polyester foam or polystyrene.

Polyester foam, also called polyurethane rigid foam, is a new type of synthetic material with thermal insulation and waterproof functions. Its thermal conductivity is low, only 0.022-0.033W/(m*Κ), which is equivalent to half of extruded board. Lowest thermal conductivity of all insulating materials. Rigid polyurethane foam is mainly used in building exterior wall insulation, roof waterproof insulation integration, cold storage insulation, pipeline insulation materials, building panels, refrigerated vehicles and cold storage insulation materials, etc.

Polystyrene is colorless and transparent, can be colored freely, and its relative density is second only to PP and PE. It has excellent electrical properties, especially good high-frequency characteristics, and is second only to F-4 and PPO. In addition, it is second only to methacrylic resin in terms of light stability, but its radiation resistance is the strongest among all plastics. The most important feature of polystyrene is that it has very good thermal stability and fluidity during melting, so it is easy to form and process, especially injection molding, and is suitable for mass production. The molding shrinkage rate is small, and the dimensional stability of the molded product is also good.

Both of these materials are suitable for making insulation layers.

The porous bricks can be made of concrete or ceramics or gypsum. These materials are the more commonly used brick materials.

Further, the inner wall of the heat preservation hole is provided with a reflective layer made of metal foil. The reflection layer is arranged on the inner wall of the heat preservation hole, which can reflect the heat radiation and further reduce the heat radiation.

The beneficial effects of the utility model are: the structure design of the thermal insulation brick obtained by the above design in the utility model is ingenious, and it has various thermal insulation designs.
