Description
Technical field
The invention belongs to building material technical field, particularly composite heat insulation block.
Background technology
In recent years, building energy conservation has become the importance of energy-saving and emission-reduction measure, along with global energy is nervous; The requirement of building energy saving rate is also increasingly high; Most of areas rises to 65% from energy-conservation 50%, some areas even require 75% energy-conservationly, and this just proposes higher requirement to the heat-insulating property of exterior wall insulation blocks; When improving the material heat-insulating property, can't reduce the intensity and the safety of material.
Existing market generally adopts following scheme through energy-conservation requirement: adopt insulation blocks to build by laying bricks or stones; The outer then warming plate system of pasting reaches 65% even 75% energy-conservation, and insulation blocks often has light-weight aggregate thermal insulation building block, Autoclaved aerated concrete blocks brick and autoclaved fly ash building block etc., singly is difficult to satisfy energy-conservation requirement with insulation blocks; Warming plate often has rock cotton board, phenolic board, organic heat-insulating plate and inorganic heat preservation plate; This scheme exposes problems, as: fire safety problem, hollowing, cracking problem and durable years problem etc.; Though the part material has solved fire safety problem; But all have some defectives to some extent, big like the rock cotton board difficulty of construction, the phenolic board ageing resistace is poor, insulation layer and building can't form the common life-span.
Therefore on the market demand a kind of can with the same life-span of building, construction technology is simple and direct, and the heat insulation building block of good heat insulation effect is arranged.
Summary of the invention
The objective of the invention is deficiency and defective, a kind of composite heat insulation block is provided to existing various heat-insulation systems.
The present invention solves its technical problem and adopts following technical scheme: a kind of expanded and vitrified small ball composite heat insulation block [390*240* (80～240) mm] is made up of air heat-insulation layer, light filler heat insulation layer and bearing course; Wherein, said bearing course adopts the preparation of expansion vitrification bead heat-preserving material; Said air heat-insulation layer is symmetrically arranged double-deck air isolation layer, and said double-deck air isolation layer adopts many cavitys cross structure; Said light filler heat insulation layer is arranged at the middle part, the filler of light filling insulation therebetween.
Above-mentioned expanded and vitrified small ball composite heat insulation block, it is further characterized in that: the building block outer periphery is equipped with a plurality of grooves, can form the heat insulation vestibule of air of a plurality of closures during the building block splicing between groove and groove.The material category of the adiabatic layered material of said light filler: organic material isolation layer, light inorganic material isolation layer, organic and inorganic composite heat insulation layer, change in size scope 20-80mm.Said air heat-insulation layer change in size scope 14-29mm.
Advantage of the present invention:
1, through selecting different light filler heat insulation layer materials and corresponding varying sized, improves the thermal resistance of composite heat insulation block greatly, satisfy the energy-conservation requirement of different regions, really realize building energy conservation.
2, after composite heat insulation block is built completion by laying bricks or stones, need not to adopt interior wall or exterior wall heat-preserving system, reduce engineering cost, reduce hollowing, cracking risk, simplify construction technology, realize and the same life-span of building.
3, bearing course adopts the incombustible material expanded and vitrified small ball as light aggregate, guarantees the fire-protection rating A level of composite heat insulation block, reduces disaster hidden-trouble.
Description of drawings
Fig. 1 is the composite heat insulation block structural representation of the embodiment of the invention.
Fig. 2 is to be the light filler heat insulation layer size sketch map of reference line with vertical central axis.
Fig. 3 is to be the air heat-insulation layer size sketch map of reference line with vertical central axis.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further to set forth in detail.
The composite heat insulation block of present embodiment is made up of air heat-insulation layer, light filler heat insulation layer and bearing course, and is as shown in Figure 1, and the composite heat insulation block structural representation is characterised in that:
1. bearing course adopts the preparation of expansion vitrification bead heat-preserving material, and coefficient of thermal conductivity is low, strengthens heat insulation effect, optimizes each component of proportioning bearing course, satisfies the block strength requirement.
2. the double-deck air isolation layer is all adopted in both sides; Utilize the still air coefficient of thermal conductivity low, the double-deck air isolation layer adopts many cavitys cross structure, and many cavitys are divided into a plurality of confined spaces with air heat-insulation layer; Further reduce the air thermal convection current; Stop heat transmission, many cavitys air layer that is staggered can effectively prolong the propagation distance of heat in bearing course, increases the heat fade amount.
3. the light thermal-insulation filler heat insulation layer of light thermal-insulation filler is adopted in the intermediate layer, utilizes the low heat conduction of light thermal-insulation filler, further stops calorie spread, has also avoided the harmful effect because of adopting the excessive thermal convection current effect that causes of air heat-insulation layer area to promote simultaneously.And the light filler heat insulation layer can be selected different light thermal-insulation fillers according to different heat preservation energy-saving needs; Can also select the thickness of different light filler heat insulation layers according to different heat preservation energy-saving needs, be reference line varying sized (Fig. 2) with vertical central axis, and corresponding air heat-insulation layer is a reference line with vertical central axis; Change (Fig. 3) according to light filler heat insulation layer change in size; Thereby further improve the thermal resistance of composite heat insulation block, satisfy energy-conservation requirement, optimize cost.
4. many groove design are adopted in the building block periphery, and when concrete block masonry became body of wall, the groove between two building blocks will be spliced to form the heat insulation vestibule of air of a plurality of closures, thereby solve the heat bridge problem of building block and blockhouse.
The material category of light filler heat insulation layer in the composite heat insulation block: organic material isolation layer, light inorganic material isolation layer, organic and inorganic composite heat insulation layer, change in size scope 20-80mm.Composite heat insulation block air isolation layer change in size scope 14-29mm.The composite heat insulation block performance indications are seen table 1.
