Abstract
The invention discloses a phase-changing heat preservation composite building block, belonging to the technical field of building materials. The body of the building block is made of lytag concrete. Eight rectangular through holes with the same thickness are formed inside the building block, in which four through holes in same shape are longer and the other four through holes in same shape are shorter. The eight through holes are arranged in four rows, in which each row consists of one longer through hole and one shorter through hole, and each row of through holes is arranged in a staggered manner mutually. The four longer through holes are internally filled with a heat preservation material, and the four shorter through holes are internally filled with gypsum boards made of a phase-changing material. A hole-like structure is selected reasonably, so that the mechanical property of the light aggregate hollow bricking block is ensured, and the thermal resistance of the building block is improved; the gypsum board made of the phase-changing material is prepared, so that the filled phase-changing material is unlikely to leak and is good in material compatibility of the main body of the building block; and the problems of the traditional hollow building block that the specific heat capacity of an exterior wall is reduced and the mechanical property is insufficient caused by improved heat-insulating property are solved, so that the indoor thermal comfort is improved, and overall energy consumption of a building is reduced.
Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of phase-transition heat-preserving composite block.
Background technology
Due to the effect of thermal resistance and thermal capacitance, temperature wave and hot-fluid ripple can produce decay during by architectural exterior-protecting construction and postpone.At present, architectural exterior-protecting construction adopts traditional organic heat-insulating heat-barrier material to satisfy code of building energy efficiency for the requirement of thermal resistance of enclosing structure usually.Although these thermal insulation materials have lower thermal conductivity value, can effectively increase the thermal resistance of space enclosing structure, they have potential safety hazard mostly, and application life is limited, and has lower specific heat capacity value.Present building adopts frame construction in a large number, and the body of wall of this structure is called infilled wall, and they are hollow, lightweight and middle matter body of wall mostly, and are wherein in the majority with concrete holllow building block wall.In order to improve the thermal and insulating performance of external wall, usually adopt light aggregate hollow block, and increase the hollow rate of building block; In addition, in order to reduce the heat bridge of building block inside, usually the limit rib with building-block blocks.Although these ways can improve the heat-insulating property of building-block, ignored its mechanical property.Above these factors can make the specific heat capacity value of whole body of wall lower, and the temperature, the hot-fluid that cause the body of wall inner surface to produce along with the fluctuation of ambient temperature, hot-fluid by a relatively large margin fluctuate, thereby make the indoor air temperature fluctuation, and indoor comfort degree reduces; Simultaneously, cause the frequent keying of room conditioning or can not keep the steady working condition operation of long period; Due to air-conditioning equipment the startup stage and unsteady-stage conditions when operation power consumption higher, just increased the energy consumption of air-conditioning system.
Phase-change material has heat storage performance when phase transformation occurs, can absorb or discharge a large amount of latent heat, and own variations in temperature own is little.Phase-change material is reasonably applied in building-block, be conducive to reduce the temperature wave amplitude of external wall inner surface, thereby make interior temperature more steady, improve comfort level; Simultaneously, reduce the energy consumption of air-conditioning system equipment.
Summary of the invention
The purpose of this invention is to provide a kind of phase-transition heat-preserving composite block, make the problem of the reduction of external wall specific heat capacity and mechanical property deficiency due to the raising heat-insulating property to solve traditional lightweight, middle matter concrete hollow block, thereby improve indoor thermal comfort, reduce the architectural complex energy consumption.
For achieving the above object, phase-transition heat-preserving composite block of the present invention can adopt following technical scheme:
A kind of phase-transition heat-preserving composite block, comprise block body and connect the through hole that at least four of block body is arranged lengthwises, be provided with length direction in described each row and extend long the first through hole and the second shorter through hole of arranging, and described two first adjacent through hole widths stagger, two second adjacent through hole widths stagger, and half of the distance between described the first through hole and the second through hole and the length sum of the second through hole equal the first through hole length half, fill the phase-change material gypsum plank in fill insulant material in described the first through hole, the second through hole.
Compare with background technology, the beneficial effect of phase-transition heat-preserving composite block of the present invention is:
1, phase-change material (aliphatic acid or paraffin) gypsum plank is put into the hole of building-block, can utilize phase-transition heat-storage, the exothermicity of phase-change material, make the hot-fluid in the external world on daytime in summer can not enter indoor, and make external wall inner surface and indoor temperature and hot-fluid fluctuate more steady, improve comfort level, and reduce the energy consumption of equipment.
The phase-change material gypsum plank of 2, filling is difficult for causing the leakage of phase-change material, and is good with the block main body material compatibility.
3, described block structure is not blocked the limit rib of building-block, thereby has guaranteed the mechanical property of light aggregate hollow block.
4, due to increase the hole row than the successful of increase hole thickness many, therefore in order to guarantee that building-block has higher thermal resistance value, described type reduced traditional building-block hole thickness, increased the hole row, be four row hole structures, thereby improved the thermal resistance value of building block.
5, the staggered structure of each round is adopted in described building block, has avoided the existence of too much heat bridge, thereby makes the thermal resistance value of building block maintain higher level.
