Description

The self-insulating concrete building block

Technical field:

The utility model relates to a kind of self-insulating concrete building block, belongs to building material technical field.

Background technology:

Along with becoming increasingly conspicuous of energy problem, country more and more payes attention to building energy conservation.The height of building efficiency directly influences the energy security strategy of China, also can have influence on the sustainable development of China.Building energy consumption (comprise and build energy consumption, life energy consumption, heating air conditioning etc.) accounts for 30% of whole society's total energy consumption.Propelling building energy conservation work not only can energy conservation, alleviate environment pollution, and continuous development of society economy is had very positive effect.

Present stage, China mainly adopted External Thermal Insulation Technology for External to improve the thermal and insulating performance of building masonry wall, as glue powder polyphenyl granule exterior wall outer heat preservation system, expansion polyphenyl plate (EPS, XPS) external insulating system for thinly plastered external wall, inorganic heat-insulating mortar exterior wall outer heat preservation system, polyurathamc external thermal insulation system etc., these broad application have been pushed forward the building energy conservation work of China comprehensively.But there are limitation respectively in time-proven, various external thermal insulation systems in technology, quality and construction, the most outstanding life-span, the safety problem of being to use.The common regulation of national and local correlation technique rules application life is 25 years, exists asynchronous, inflammable, easy to crack, hollowing of outer heat preservation system and building application life, comes off etc., many potential problems such as weather resistance is relatively poor.Therefore External Thermal Insulation Technology for External is subjected to querying in many ways.

Along with the pushing forward comprehensively and deepening constantly of building energy conservation work, active demand has been proposed multi-form heat insulation system, the energy-conservation and structure-integrated important directions that becomes the structural system development and use.Energy-conservation and the structure-integrated architectural structure system that not only enriched has also solved the same life problems of heat insulation system and building preferably, has obtained reinforcement at aspect of performances such as antidetonation, safety.Therefore, development, the building block of promotion and application self-insulating concrete will advance China's building energy conservation work to develop in a healthy way, and have significant social and technology economy advantage.The self-insulating concrete building block is as a kind of Multifunction materials for wall, and good endurance is prevented fires, easy construction, and integrated cost is low, with the same life-span of building, therefore has broad prospect for its application, is that one of direction will be given priority in China building block field from now on.

The self-insulating concrete blockwork should be from block performance, build by laying bricks or stones with plastering mortar performance, masonry technology, vertical puzzle joint and the blocking-up of bed joint heat bridge, the processing of beam column built from concrete position heat bridge, anti-crack and anti-seepage technology etc. and study by system engineering, solving its high standard energy conservation project quality and requirement in application life under various weather conditions, is the correct technology path of self-insulating concrete blockwork.Design of building block piece type and structure design are to improve its thermal property fundamental way, are the important effective ways that solves masonry anti-crack and anti-seepage, blocking-up puzzle joint heat bridge.

Self-insulating concrete building block practices well is to fill heat preserving and insulating material in the building block hole at present, and the middle rib of limit rib and width easily forms structural heat bridge, and blockwork mortar mortar joint also exists heat bridge, and these have all influenced the blockwork thermal property.

Summary of the invention:

For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of type reasonable in design with structure, physical and mechanical property is stable, the thermal property excellence, it is convenient to use to construct, antidetonation, sound insulation, fireproof performance is good, the anti-leakage common quality defect is few, overall economic efficiency is high with the synperiodic self-insulating concrete building block of building structure life.

The utility model technical solution problem adopts following technical scheme:

The self-insulating concrete building block comprises block body and is located at middle rib in the described block body along the length direction of building block that be respectively equipped with T shape hole in the inner chamber both sides of described block body, two T shape holes form symmetry with described middle rib; Be arranged with the opening U-shaped hole of in block body, shrinking at the both ends of described block body.

Described U-shaped hole is a clear opening, and described T shape hole is clear opening or half-blindness hole or blind hole.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, block body of the present utility model is provided with "T"-shaped hole and " U " shape pore structure, satisfying under the physical mechanics standard-required, " U " shape pore space structure of the "T"-shaped pore space structure of the middle rib of cancellation width and prolongation limit rib has reduced the heat transfer area and the heat output of heat passage (rib) in the heat transfer direction, the heat-transfer path of heat passage (limit rib) has extended, increased thermal resistance and delay the heat transfer time, significantly reduced structural heat bridge that building block causes owing to the reason of rib degree of influence the building block thermal property.

2, building block of the present utility model is provided with " U " shape hole, "T"-shaped hole, can improve the thermal and insulating performance of building block by fill heat preserving and insulating material in the hole.

3, after the utility model building block fissure of displacement is taken block, " U " type hole interpolation is gone into tabular heat preserving and insulating material, exceed block body up and down, length is longer than two " U " type hole lengths, the horizontal mortar joint major part is blocked by tabular heat preserving and insulating material, perpends is blocked by tabular heat preserving and insulating material fully, and the mortar joint heat bridge reduces greatly to the degree of influence of block masonry thermal property.

4, the utility model block body end face is provided with vertical mortar joint mortar pin groove, forms perpends mortar pin key after the concrete block masonry, improves block masonry shear strength and anti-seismic performance; The perpends mortar is full, closely knit, has improved impervious, the anti-performance of leaking of blockwork.
