Problems solved by technology

The utility model patent titled "ceramic concrete hollow block" (patent number ZL88214874.5) disclosed in the Chinese patent literature, this technology is a concrete hollow block made of cement as a binder and lightweight aggregate as a raw material. Because of its light weight and high strength, this technology has been widely used in a certain period of time, but the products involved in this technology do not have thermal insulation performance, so if this product is used as an exterior wall in the north, it usually requires additional insulation. Take insulation measures
The defect of this technology and the above-mentioned technology is that it does not consider the heat conduction problem of the mortar layer connected longitudinally and between the blocks in use.

Embodiment 1

[0018] Take the thermal insulation block with a length of 410mm, a total width of 200mm, two sides, each width of 95mm, and a height of 200mm as an example:

[0019] as attached figure 1 , 2 , 3 shows that the thermal insulation block is composed of a Z-shaped thermal insulation block shell 1 and a thermal insulation material core block 2. There is a dislocation through hole in the block, and the thermal insulation material core block 2 is filled in the through hole. When in use, it also includes Sheet-shaped insulation block 3; the upper surface of the insulation material core block 2 is 1 cm lower than the surface of the block. The thickness of the insulation block is 2cm, and the 1cm reserved space embedded in the block is reserved. At the same time, the upper surface of the sheet-like insulation block is in direct contact with the bottom end surface of the insulation block of the upper layer when the wall is built. The horizontal sand-ash joints are all isolated by insul...

Embodiment 2

[0023] The difference between this embodiment and embodiment 1 is, as figure 2 , 3 It is shown that the section shape of the sheet-like insulation block 3 is preferably designed to be convex, and grooves 4 are formed on the two sides of the protruding part. 5. Increase the connection strength between blocks. The material ratio of the Z-shaped thermal insulation block shell 1 is, by weight percentage, using 45% of clay ceramsite with a particle size of 8-15mm, 11% of cement as a binder, adding 44% of cinder, and stirring evenly Finally, use 20% water to vibrate and extrude in a Z-shaped mold.

[0024] The thermal insulation material core block is made of expanded perlite and industrial liquid sodium silicate, and then it is pressed and formed in the ceramsite block. The ratio of the expanded perlite and the industrial liquid sodium silicate is as follows: the expanded perlite accounts for 66% by weight, and the industrial liquid sodium silicate with a concentration of 20% a...

Embodiment 3

[0028]The difference between this embodiment and Embodiment 1 is that the material ratio of the Z-shaped heat-insulating block shell 1 is, by weight percentage, 40% of shale ceramsite with a particle size of 8-15mm, and 12% of cement. Adhesive, add 48% coal cinder, stir well and use 28% water to vibrate and extrude in Z-shaped mould.

[0029] The thermal insulation material core block is made of expanded perlite and industrial liquid sodium silicate, and then it is pressed and formed in the ceramsite block. The ratio of the expanded perlite and the industrial liquid sodium silicate is as follows: the expanded perlite accounts for 71% by weight, and the industrial liquid sodium silicate with a concentration of 35% accounts for 29%.

[0030] The sheet-like insulation block 3 adopts a formed polystyrene board, and its thickness is 30mm.

[0031] Production method is the same as embodiment 1

Abstract

The invention relates to a heat-insulation block for building wall, especially the heat-insulation block with energy saving and heat insulation performances applied for manufacturing outer wall, belonging to the building material. The production in invention is Z-shape. Heat-insulation core block is filled in the shell. The upper surface of said heat-insulation core block is lower than the heat-insulation block by 1-2cm. In using, it also comprises a sheet heat-insulation block embedded on the upper part of block partially. The shape of sheet heat-insulation block must obligate space to satisfy that it can insert into the upper part of heat-insulation block partially while the upper surface of sheet heat-insulation block is contacted with the bottom face of block in last layer in buildingwall directly. The merit of invention is that after the block in invention is adopted to build wall, the heat-insulation material crosses in wall so that not only heat exchange of portrait masonry joint in wall is solved but also heat exchange of transversal masonry joint in wall is solved; cold-effect effect generated by masonry joint is solved; when the product in invention is used there is no need to do heat-insulation treatment for outer wall furthermore and cost is saved.

Description

technical field [0001] The utility model relates to a thermal insulation block for building walls, which relates to building materials, in particular to a thermal insulation block suitable for making outer walls with energy-saving and thermal insulation properties. Background technique [0002] In recent years, ceramsite blocks are mostly used as exterior wall materials in the building materials industry. The utility model patent titled "ceramic concrete hollow block" (patent number ZL88214874.5) disclosed in the Chinese patent literature, this technology is a concrete hollow block made of cement as a binder and lightweight aggregate as a raw material. Because of its light weight and high strength, this technology has been widely used in a certain period of time, but the products involved in this technology do not have thermal insulation performance, so if this product is used as an exterior wall in the north, it usually requires additional insulation.
