Abstract
The invention relates to a thermal-bridge-free thermal insulation building block made of straw and raw soil. The building block comprises intermediate thermal insulation blocks, lateral thermal insulation blocks, raw soil layers and midribs. Thicknesses of the intermediate thermal insulation blocks are twice of those of lateral thermal insulation blocks. The midribs are formed between the adjacent thermal insulation blocks on a same layer, and the midribs on adjacent layers are staggered mutually. The lateral thermal insulation blocks stretch to the outer edges at two ends of the building block. The heights of the thermal insulation blocks are identical to the height of the building block. The thermal-bridge-free thermal insulation building block made of straw and raw soil and a producing method thereof have the advantages that a great many agricultural wastes can be consumed to produce energy-saving building wall materials, so that not only environmental pollution can be reduced, lots of fertile farmland clay is saved, wastes are turned into wealth, and lots of bunker coal can be saved. The energy-saving capacity of buildings is improved greatly, the thermal insulation effect is enhanced, and the building block is durable, safe, fire proof and effective in sound insulation. The construction is convenient, the speed is fast, the building efficiency is high, materials are saved, the building block weight is light, and the cost is low.
Description
Technical field
The present invention relates to the building block of a kind of insulation immature soil, particularly without heat bridge straw immature soil insulation blocks and preparation method thereof.
Background technology
Earth building mainly is that the undisturbed soil of only doing simple processing with roasting not is the building that material is built agent structure.Earth building starts from the artificial chisel cave, existing long history.From beacon tower, grave and the ruins, Gucheng etc. that retain ancient times, can see that ancients use the situation of immature soil constructing architecture thing.Earth building is widely distributed, almost extend over the entire globe.Earth building exhibition was all over the world once held at fluffy skin Du of Paris, FRA Arts and Culture center in 1981.There is approximately in the world now 1/3 population to live in the earth building.
Earth building is human from one of original the most representative feature that enters civilization, is evidence and the rarity of the historical civilization of the Chinese nation, also is that ancestors leave us for and enrich important content in the legacy.Earth building is risen in the central and west regions of China, and this area's dry and rainless, abundant loess formation become China's natural building material at civilization initial stage.Earth building structural system has roughly experienced soil-covering structure system (live in caves, cave dwelling), rammed loam construction system and adobe construction system three phases.As far back as the Stone Age, the primitive man has just built various earth buildings, the magnetic mountain culture before modern 7000, Pei Li Gang culture, the culture of the earth gulf period, existing circular, square location, half paintpot formula room.The rammer soil technology that about 4000 prehumans tentatively grasp, tool is characteristic to be to ram village community and the city wall that civil engineering is made.The appearance of adobe construction makes earth building all reach very high level aspect the reservation mankind and natural Attachment and the formal aesthetic sense.The earth building that we can see today, mostly be retained in northwest, loess plateau to the region.Along with the progress in epoch, socioeconomic development, vast building houses of countryside progressively replaces sun-dried mud brick, earth rammer body of wall with clay brick, makes this ancient constructional materials move towards to wither away.Yet along with the arrival in conservation culture epoch, this was once caused again knowledgeable people's concern by the human rarity that industrial civilization is forgotten.
As one of mankind's construction method the earliest, earth building in a lot of local sites of ancient culture remains, has its historical relic to leave over now, as ruins, grave and the ruins, Gucheng etc. on ancient Great Wall, can see that ancients use the vestige of immature soil constructing architecture thing.Earth building is widely distributed, almost extend over the entire globe.Villager in 640,000 square kilometres of scopes of Chinese loess plateau still lives in cave dwelling and other earth buildings mostly.Because the difference of geographical conditions, life style, historical tradition, National Folk Customs, the earth building of each department also respectively has characteristics on construction technology and architectural style, and this has become the ingredient of various countries' architectural culture.And the multilayer Tulou of Fujian Province's Yongding Area can be rated as a miracle of world architecture.
The production of building block and application and resource, the energy, ecological environment and residential areas have close relationship.The raising of lifting, properties of product and the quality of the development of China's novel wall material, product restructuring, equipment technology level, construction and application technique perfect, all will further promote the development of China's building materials and building energy conservation cause, and the enforcement of China's strategy of sustainable development will be produced energetically effect.Building block building is as a kind of building types of suitable China's national situation, and its superiority is mainly manifested in: anti-seismic performance is comparatively outstanding; Construction technology is convenient, speed is fast; For alleviating building deadweight, improving to build efficient, economical with materials, minimizing freight volume by laying bricks or stones and reduce construction costs and all play an important role, this has wide prospect undoubtedly.
Because bending resistance, shearing resistance, the rupture strength of raw soil material are very low, cause earth building to exist congenital deficiency aspect shock resistance.China is again a multiple country of earthquake, and most regional seismic activities are also quite strong.The investigation of macroscopic view after all previous earthquake shows that the earth building earthquake is generally very serious, but the erosion by wind and rain and the earthquake that also have some earth buildings to experience the centuries give a violent shake to, and is still excellent.This is explanation just, and material of raw-soil structure needs only reasonable in design, and construction measure is proper, also can satisfy shockproof requirements.
In today of people's common concern ecocrisis, energy crisis, environment pollution, cause for various reasons China's Forest Resources to lack ecological environment frailty.From the idea of human settlement's sustainable development, and on the social aspect of conservation culture, during this ancient constructional materials of re-examine " immature soil ", will recognize clear-headedly that " immature soil " is promising green construction material.
The relevant patent of invention of immature soil building block is not yet arranged at present; To promote the development of immature soil building block without the exploitation of heat bridge straw immature soil insulation blocks.
