Rod-shaped connected composite self-insulating building block and production method thereof

Abstract

The invention discloses a rod-shaped connected composite self-insulating building block and a production method thereof, which are characterized in that the building block is composed of an outer concrete slab and a middle foam concrete slab, wherein the outer concrete slab is prepared from cement, fine aggregates, fly ash, fiber-yarns and water by blending, the middle foam concrete slab is formed by cutting a large-sized plate prepared from cement, fly ash, light aggregates, a foamed foaming agent and water by blending, and the middle of the middle foam concrete slab is provided with a through hole. The production method of the building block comprises the following steps: preparing a large-sized foam concrete plate, cutting the large-sized plate according to a design size, and arranging a through hole on the large-sized plate; casting a bottom concrete slab in a building block mold; putting a foam concrete slab on a baseplate, filling concrete in the through hole, and casting a top concrete slab; and demoulding the building block, carrying out piled maintenance on the building block, and laying the building block. By using the method, foam concrete and the outer concrete slab are closely attached, so that the thermal insulation properties of the building block are improved; and the building block has the advantages of light weight, energy conservation and environmental friendliness.

[0002] With the sharp increase in the world's energy consumption and the massive consumption of various energy resources, energy conservation is an issue of increasing concern to all countries. Building energy conservation is of great significance to my country's sustainable development. According to the country's requirements for building energy conservation, building The external wall of the building needs to add an insulation layer on the inside or outside of the current wall material to meet the requirements. If the external wall insulation is used, the insulation material is located on the outside, and the construction is cumbersome and unsafe. If the external wall is used for internal insulation, it will bring problems. There are hidden dangers of fire and pollution, and the addition of an insulation layer will increase the construction process and lengthen the construction period. The conventional method of filling insulation materials in hollow blocks has many thermal bridges and poor insulation effects. Therefore, it is necessary to move towards composite materials. develop

[0003] The utility model patent with the notification number CN 201891208 U provides a lightweight composite self-insulating block, including two concrete layers and a lightweight insulation layer between them, but the connection between the lightweight insulation layer and the concrete layer is not tight enough, affecting Its strength and thermal insulation performance, and the block does not meet the specification "Composite thermal insulation bricks and composite thermal insulation blocks GB / T 29060-2012", the connecting wall ribs in the section at any position perpendicular to the block and the bearing surface shall not be less than 2, the sum of the areas of the connecting walls and ribs of the stressed block in any section shall not be less than 1 / 20 of the corresponding section area of ​​the product

[0004] The invention patent with the notification number CN 101881063 A provides a foam concrete sandwich self-insulating block. The block is composed of an outer wall and an inner wall, and forms a plurality of sandwich cavities, and heat-insulating light-body materials are added in the cavity to form a self-insulating block. , but the block has multiple inner walls, and the outer wall is bent in many places, and there are many places where the stress concentrates, so it is not easy to lay mortar
