Problems solved by technology

The utility model patent disclosed in the Chinese patent literature is called "ceramsite concrete hollow block" (patent No. CN88214874.5). This technology uses cement as a binder and lightweight aggregate as a concrete hollow block made of raw materials. Because of its light weight and high strength, this technology has been widely used in a certain period of time, but the products inv...

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 shown in attached drawings 1, 2, and 3, the thermal insulation block is composed of a Z-shaped thermal insulation block shell 1 and thermal insulation material cores 2. There are dislocation through holes in the blocks, and the through holes are filled with thermal insulation material cores. 2. When in use, it also includes a 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. When in use, it also includes a sheet-shaped insulation block 3 with the same or similar cross-sectional shape as the through hole. The thickness of the sheet-like insulation block 3 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 botto...

Embodiment 2

[0022] The difference between this embodiment and Embodiment 1 is that, as shown in Figures 2 and 3, the cross-sectional 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 parts, and the grooves 4 can be designed It is about 1cm, such a structure can make the sand and ash part enter the reserved space 5, and increase the connection strength between the blocks. The material ratio of the Z-shaped thermal insulation block shell 1 is, by weight percentage, 45% of clay ceramsite with a particle size of 8-15mm, 11% of cement as a binder, and 44% of cinder, and stir evenly Finally, use 20% water to vibrate and extrude in a Z-shaped mold.

[0023] 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 fol...

Embodiment 3

[0027] 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.

[0028] 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%.

[0029] The sheet-like insulation block 3 adopts a formed polystyrene board, and its thickness is 30mm.

[0030] 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 building wall 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 disclosed in the Chinese patent literature is called "ceramsite concrete hollow block" (patent No. CN88214874.5). This technology uses cement as a binder and lightweight aggregate as a concrete hollow block made of raw materials. 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 me...
