Embodiment 1

[0024] Example 1 as figure 1 The composite self-insulating concrete hollow block is composed of an inner part 1, an insulating part 2 and an outer part 3. The inner part 1 and the outer part 3 are made of fly ash as the main raw material, cement, water-quenched slag and water are added. The material of the heat preservation part 2 is polystyrene resin; the inner part 1 and the outer part 3 clamp the heat preservation part 2 through two pairs of dovetail grooves 4, so that the inner part 1, the heat preservation part 2 and the outer part 3 are tightly combined; The center of the outer part 3 has a rectangular opening 5 with rounded corners on the front; two protruding lock heads 6 and two recessed lock grooves 7 are respectively provided at both ends of the outer part 3 . A V-shaped groove is respectively arranged at both ends of the thermal insulation part 3 .

[0025] The external dimension of this block is 394mm * 194mm * 200mm. After inspection, its density is 765kg / m 3 ...

Embodiment 2

[0027] Embodiment 2 produces composite self-insulating concrete hollow block according to the following steps:

[0028] ①Put the expandable granules into the foaming cylinder and foam them with steam until the pressure reaches 1800kPa, and then pass the obtained granules into a foam block through a molding machine for later use;

[0029] ② fully mix fly ash, cement, water-quenched slag and water according to the mass ratio of 20:14:76:170, stir evenly, and prepare the obtained slurry for later use; Sorted raw ash; the cement is Portland cement labeled P.C32.5; the water-quenched slag is mainly calcium silicate and calcium aluminosilicate produced during blast furnace smelting pig iron. Molten material, material that is granulated by water quenching;

[0030] ③ Add the above-mentioned mixture into the molding machine, and form it through molding vibration, and the vibration acceleration is 15g; before the masonry is formed, insert the insulation layer with dovetail groove stru...

Abstract

The invention discloses a composite self-heat-insulation concrete hollow building block comprising an internal member, a heat-insulation member and an external member, wherein the internal member and the external member are made by adding cement, water granulated slag and water into fly ash as a main raw material; the heat-insulation member is made from foaming resin; the internal member and the external member are used for clamping the heat-insulation member through a dovetail groove to ensure that a building block, a heat-insulation material and a protection layer are tightly bonded together so as to improve the tensile strength among the protection layer, a heat-insulation layer and the building block; a through hole is arranged in the center of the external member to reduce the weight of the external member and improve heat insulation and sound insulation effects; and a convex lock head and a concave lock groove are respectively designed at two ends of the external member so that an interlocking mechanism is formed between building blocks. The building block provided by the invention has the advantages of favorable self-heat-insulation property, convenience for construction in masonry, smooth masonry wall surface, great reduction of building plastering thickness; and meanwhile the shock resistant capacity of a building wall is improved due to the interlocking mechanism. The composite self-heat-insulation concrete hollow building block can be used for wall materials of buildings and structures.

Description

technical field [0001] This invention relates to block elements in building components, and in particular to concrete blocks. Background technique [0002] Existing self-insulating concrete hollow blocks mainly adopt several insulation methods: one is to insert insulation materials in the cavity of the block, such as Chinese patent application No. 01109265.3 "Insulation Block and Insulation Wall Structure Utilizing Insulation Block" ", No. 02254823.8 "Multifunctional Composite Block", etc., the second is to add insulation materials and accessories between the blocks, such as No. 200720073982.2 "Concrete Thermal Insulation Module Block", etc., and the third is to improve the block material to enable self-insulation , such as No. 200720013576.7 "A Core Foamed Concrete Thermal Insulation Block", No. 200910245114.1 "Steam-free fly ash aerated thermal insulation block and its preparation method", etc. These patented technologies can give concrete blocks a certain thermal insulat...
