Description

Building heat preservation blocks and production method thereof

Technical field

The present invention relates to self-heat conserving composite block and production method thereof in the building block.

Background technology

Building energy conservation is to carry out conservation-minded society, a fundamental state policy of sustainable development.Under the policy guidance of the standard of carrying out building energy conservation 50% and realization building energy conservation 65%, a large amount of energy-saving heat preservation building blocks constantly occur, as some in the building block hole filled and process plate or the cast foam beads composite heat insulation block, still there is the water absorption rate height in above-mentioned insulation blocks, big, the easy to crack and heat bridge effect problem of drying shrinkage.Occur a kind of haydite in recent years and strengthened aerated-block, adopt foam concrete to mix a large amount of haydites and do lightweight aggregate, solved insulation blocks lightweight, high-strength, drying shrinkage is little, thermal property is good technical requirements preferably.But haydite need use a large amount of clays, also will be through firing, haydite strengthens the production of aerated-block and adopts the integrated poured technology of single chamber pattern, the building block matrix is continuous foamed concrete material, the intensity that still has MATRIX CRACKING and produced subtracts mistake, infiltration and heat bridge problem, and has shortcomings such as technology is numerous and diverse, cost of production height.At the problems referred to above by retrieval, do not find relevant technical solution as yet.

Summary of the invention

Purpose of the present invention just provides a kind of building heat preservation blocks, the easy cracking that exists with the building block matrix that solves in the prior art, and the intensity that is produced thus subtracts mistake, infiltration and heat bridge problem, and another object of the present invention makes the production method that described building heat preservation blocks is provided.

To achieve these goals, the present invention has adopted following technical scheme:

A kind of building heat preservation blocks, it is framed to it is characterized in that interior bulkhead that it is made by constructional materials and external surrounding frame are formed building block, interior bulkhead middle part is provided with inner chamber, be provided with one group of dowel between external surrounding frame and the interior bulkhead, dowel is cast with light heat insulation material with being divided into exocoel independent of each other between external surrounding frame and the interior bulkhead in exocoel and inner chamber.The constructional materials that interior bulkhead is used, as typically can adopting coagulation materials such as cement, microlith, sand, haydite, bulkhead and dowel in molding or mould pressing process are made.

All pour into a mould in described exocoel and the inner chamber and be filled with the foam concrete that contains the certain proportion haydite, the ratio of haydite in foam concrete is 2%-10%.Perhaps be filled with polyphenyl foam particle or crushed crude pearlite in inner chamber, be cast with the foam concrete that contains the certain proportion haydite in the exocoel, the ratio of haydite in foam concrete is 2%-10%.

Can also be filled with other light heat insulation material in the inner chamber, as heat insulating materials such as foam concrete, polystyrene foam particles, polyurethane foam materials.

The present invention also comprises a kind of production method of building heat preservation blocks, it is characterized in that having adopted the following step:

(1), it is framed to suppress the described building block of claim 1 with brick equipment;

(2), pour into a mould or be filled with light heat insulation material in the exocoel between interior bulkhead and external surrounding frame;

(3), cast or filling light thermal insulation material in the inner chamber of interior bulkhead;

(4), also can treat pour into a mould or filling light thermal insulation material do solid after, the external surrounding frame at excision two ends.

The invention has the advantages that: 1, composite heat insulation block of the present invention, have lightweight, high-strength, water absorption rate is low, drying shrinkage is little, thermal technology's property is good, can satisfy the designing requirement of building energy conservation 65%, build the wall self-insulation system of system by laying bricks or stones for foundation, a kind of safe, reliable, short construction period, novel wall self-thermal insulation material that comprehensive cost is low are provided.2, the framed making of building block provided by the present invention is simple, can adopt conventional block material, through molding, compression molding all can, as utilize conventional building block pressure forming machine (technology) but and raw material both the production building block was framed.3, can be directly in the framed cavity of building block, cast, the multiple suitable material of filling, the framed material of imbedding after the sclerosis with cast becomes the composite monolithic of a multilayer, both can cut.Therefore to have production method simple in the present invention, do not need special-purpose casting mold not want the demoulding, group mould.
