The invention relates to a multilayer brick concrete laying insulation wall body and a construction method thereof. The insulation wall body is a brick concrete structure. A brick masonry is circularly laid by the combination of the following three layers. An insulation layer is formed by a middle insulation layer, an external insulation layer and an internal insulation layer which are circularlyand alternately arranged in the brick masonry from bottom to top sequentially. A first layer of brick masonry is formed by two stripes of stretcher bricks from a first layer to a fifth layer; a gap for the middle insulation layer is reserved between the two stripes of the stretcher bricks; the gap is filled with an insulation material; and the outside of a reinforced concrete structural column ata corner is coated by the structural column external insulation layer. A second layer of brick masonry is laid by paralleled header bricks from a first layer to a fifth layer, and an external insulation layer is adhered to the outsides of the header bricks. A third layer of brick masonry is laid by paralleled header bricks from a first layer to a fifth layer; the outside of the header bricks fit the outside of the wall body; and the internal insulation layer is adhered to the insides of the header bricks. By changing the laying mode of the bricks, the construction method can meet the requirements of the wall body on insulation effect. The construction method which is simple and saves materials and energy can be widely applied to brick concrete insulation wall bodies.

A method of insulating a building that includes one or more existing external walls 2 and an existing roof structure 4 supported by the walls, comprises constructing a first external shell structure 24a that covers an outer surface of at least one external wall, said shell structure being spaced from the outer surface of the wall to provide a wall void 28 between the external wall and the shell structure. A second shell structure 24b is constructed that extends around or through (fig.15) the existing roof structure 4 and provides an enclosed roof void 26b that extends around or through the roof structure. The roof void 26b is interconnected with the wall void 26a. The wall void 26a and the roof void 26b are filled with an insulating material to provide a continuous insulating layer 28 extending through the wall and roof voids to eliminate thermal breaks between them. A vapour resistant membrane is preferably included between the external wall and the wall void and below the roof void.

The invention relates to a heat bridge-free self-insulation building block comprising insulation boards and concrete, wherein the insulation boards are arranged in the concrete at intervals in four rows; concrete ribs are formed between adjacent insulation boards in the same row; the concrete ribs and the insulation boards in different rows are staggered; the insulation boards in even layers and odd layers respectively extend out of the left side and the right side of the building block to form outwards-extended insulation boards; and all the insulation boards extend out of the top surface of the building block to form outwards-extended insulation boards. The building block disclosed by the invention has the beneficial effects that the heat bridge effect of non-insulation parts of the building block, masonry mortar joints and the like can be avoided with no need of adopting other insulating layers, so that the energy saving ability of the buildings is greatly increased and the heat insulation effect is enhanced and has the advantages of durable service, safety, fire prevention and effectiveness in sound insulation. According to the invention, the heat preserving layer does not need to be added, therefore, the construction technique is convenient, the speed is high, the building efficiency is increased, the material is saved, the transportation volume is reduced and the construction cost is reduced.

The invention relates to a thermally isolating housing (11) for a cooling device (10) comprising an internal and external surface layer (17, 19) in addition to a thermally insulating layer (20) inserted between entrances of the surface layers (17, 19) in the form of fluidic components, introduced through at least one entrance opening (23) arranged close to a machine chamber (21) for receiving a condensed refrigerating medium (16). A problem of the known cooling device is that the thermally insulating material (20) which turns into mousse is introduced by the high processing pressure thereof, preferably in the upper part of the thermally insulating housing (11). A shrinkage formation therefrom can not be prevented in the deep lying sections of the housing. According to the invention, at least in the neighbouring area of the entrance opening (23) a flat profile (24) is provided for using as a brake for the mousse.

The invention relates to an external wall heat insulation structure and a construction method thereof. A part of a filling wall body outwards projects out of the outer side edges of a building structure post, a structure wall, a beam and a floor slag; at least two crisscross structural belts are formed; and the at least two crisscross structural belts form a groined structural belt on the whole building elevation. On the basis of remaining the effects of avoiding a heat bridge and preventing inside moisture condensation of a conventional outer heat insulation structure, a construction method is optimized, so that the advantages are realized through being compared with conventional outer heat insulation in aspects of material saving, labor saving, fireproof safety, thermal performance and the like.

The invention discloses a heat-preserving cast-in-situ stripe for a novel sintered shale heat-preserving hollow building block wall body. The heat-preserving cast-in-situ stripe comprises novel sintered shale heat-preserving hollow building blocks built on the cast-in-situ stripe of a main wall body, wherein the main wall body is partitioned into an upper wall body and a lower wall body; a layer of novel sintered shale heat-preserving hollow building blocks is built on the inner and outer sides of the upper section of the lower wall body along the width direction respectively; full-length tension meshes are arranged between the two layers of novel sintered shale heat-preserving hollow building blocks; the two ends of two longitudinal ribs in the full-length tension meshes are reliably connected with construction columns respectively; and transverse tension ribs are arranged between the two layers of novel sintered shale heat-preserving hollow building blocks along the length direction of the main wall body at certain intervals. According to the cast-in-situ stripe, a heat bridge effect between the cast-in-situ stripe and the novel sintered shale heat-preserving hollow building block wall body is avoided effectively on the premise of ensuring the high efficiency and convenience of construction, and the average heat transfer coefficient of a wall body is increased, so that the heat preserving and heat insulating properties of the wall body are improved; and meanwhile, shrinkage fractures can be reduced effectively, the job progress can be accelerated effectively, and continuous construction is realized.
