Description
Technical Field
The utility model relates to a building material field, in particular to insulation block.
Background
The building block is a block-shaped building product which is larger than the body of the clay brick. The raw materials have wide sources, various varieties, local materials and low price. The size of the product can be divided into three types, namely large, medium and small. At present, China mainly produces small and medium-sized building blocks. The building blocks are divided into concrete, cement mortar, aerated concrete, fly ash silicate, coal gangue, artificial ceramsite, slag waste and the like according to the materials. The building blocks are divided into compact and hollow building blocks according to the structure, and the hollow building blocks comprise hollow building blocks such as round holes, square holes, elliptical holes, single-row holes and multi-row holes. The compact or hollow building blocks can be used as bearing walls and partitions. China is one of the countries with the earlier building blocks, and in the 30 s of the 20 th century, the houses are built by small hollow building blocks in Shanghai. In the 50 s, cement, sandstone, slag, lime and the like are used to produce small and medium-sized building blocks in Beijing, Shanghai and other places. Fly ash silicate medium-sized building blocks are made by using fly ash, lime, gypsum, slag and the like in Shanghai in the 60 s, meanwhile, a building block forming machine and a light lifting appliance are developed, and the development of building block construction is promoted. Fly ash silicate medium-sized building blocks have been widely used and are continuously improved. In recent years, a floor block crane is developed, and the construction process is more mature.
The aerated concrete building blocks are commonly used in the filled wall body of the frame structure, although the building blocks are light in weight, the heat insulation performance can hardly meet the existing energy-saving requirement, and an external heat insulation layer needs to be additionally arranged on the outer side of the wall body. The newly made heat-insulating layer has the problems of short service life, easy water seepage of the wall body and the like.
Disclosure of Invention
To the not enough that exists among the prior art, the utility model provides a thermal insulation block can realize under the condition that the structure lightens, and the heat preservation effect is best.
The utility model discloses a realize above-mentioned technical purpose through following technological means.
A heat-insulating building block comprises a building block main body, a first hole and a second hole; the building block main body is a concrete building block, a plurality of first holes which are not connected with each other are uniformly distributed in the building block main body, the first holes are in an inverted convex shape, the small cross section end of each first hole in the inverted convex shape is communicated with a second hole, and the length of the cross section of each second hole is greater than that of the small cross section of each first hole in the inverted convex shape; and a heat insulation material is arranged in the second hole.
Further, the second hole is rectangular.
Furthermore, the length of the cross section of the second hole is equal to the length of the large cross section of the first hole in the shape of an inverted convex.
Further, each of the first holes is in an inverted convex shape, and the ratio of the length of the small cross section to the length of the large cross section of each first hole is greater than 3: 4.
and furthermore, a third hole is formed in the building block main body between the small cross section ends of the adjacent first holes, and a heat insulation material is arranged in the third hole.
Further, the heat insulation material is an extruded polystyrene heat insulation material.
The beneficial effects of the utility model reside in that:
1. the heat-insulating building block of the utility model is in the shape of an inverted convex through the first hole, so that the designed strength of the heat-insulating building block is ensured; the second hole is formed in the end portion, in the shape of the inverted-convex shape, of the small cross section of the first hole, and the heat insulation material is arranged in the second hole, so that the heat insulation building block has a heat insulation function while the strength is guaranteed.
2. Insulation block, be down "protruding" font the little cross section length and the big cross section length ratio of first hole are greater than 3: 4, the optimal heat preservation function can be ensured.

Detailed Description
The invention will be further described with reference to the drawings and the following examples, but the scope of the invention is not limited thereto.
As shown in fig. 1, the heat-insulating building block of the present invention comprises a building block main body 1, a first hole 2 and a second hole 3; the building block is characterized in that the building block main body 1 is a concrete building block, a plurality of first holes 2 which are not connected with each other are uniformly distributed in the building block main body 1, the first holes 2 are in an inverted convex shape, the first holes 2 are in the inverted convex shape and have two cross sections, wherein the cross section at the lower part is small, and the cross section at the upper part is large. The small cross section end of each inverted convex first hole 2 is communicated with a second hole 3, and the length of the cross section of each second hole 3 is larger than that of each inverted convex first hole 2; and a heat insulation material is arranged in the second hole 3. The first holes 2 are inverted and convex, so that the designed strength of the heat-insulating building block is ensured; the second hole 3 is arranged at the small cross section end of the first hole 2 in the shape of an inverted convex, and the heat insulation material is arranged in the second hole 3, so that the heat insulation block has a heat insulation function while ensuring the strength. The heat insulation material is extruded polystyrene heat insulation material.
