The adhesive of the masonry wall adopts high-intensity, non-shrink and low-expansion gelling material to replace the automatic glue injecting machine for cement mortar for construction; the wall heat preservation adopts a polyester-based polyurethane foam to inject directly into the insulation cavity in the middle of the outer wall block on site to sparkle for once molding, bonds the external wall block as an entirety firmly without seam by using the superior adhesive force and foaming tension of the polyester-based polyurethane foam, and has the advantages of simple construction, elegant figuration, excellent quality and reasonable price, and being firm and durable.

Description

Anti-seismic heat-preservation building blocks

Technical field

The utility model relates to building field, particularly provides a kind of integrated cost cheap, construction simple and fast, the anti-seismic heat-preservation building blocks of high comprehensive performance.

Background technology

China's tradition brick mixed building structure generally uses solid clay brick to do body of wall, frame construction adopts the lightweight aerated concrete building block to do filled wall, because manufacturing solid clay brick will waste a large amount of land resourcess, China's national situation is to have a large population and a few land, the soil is non-renewable scarce resource, country has prohibited the use solid clay brick now, allow to use structural clay tile and air-entrained concrete building block, because structural clay tile rib wall is thin, the gas concrete intensity difference, so that a little less than the nail-holding ability, there is very big potential safety hazard in the insulation layer of doing on the body of wall that this kind material is built by laying bricks or stones, and durability is the bottleneck of its development of puzzlement always.

The utility model content

The utility model is the anti-seismic heat-preservation building blocks that a kind of high-quality energy-saving low cost is provided at the deficiency that exists in the above-mentioned background technology.

The technical scheme that its technical problem that solves the utility model adopts is:

Anti-seismic heat-preservation building blocks does not use clay, sand, stone to do to gather materials, that uses that reproducible resources such as sintering ceramsite, flyash, building waste, chemical industry and papermaking enterprise precipitating sludge, rivers mud, slag, gangue make has an I-shaped limit rib, sizing face has the groove of laying reinforcing bar, the centre have can the filled heat insulating material hard polyurethane foam the outer shroud air chamber of incubation cavity, incubation cavity, air chamber and air chamber between have the three rows open-work small-sized hollow building block up and down in the stem stem chamber of pourable cementitious material.Far below solid clay brick, freeze proof, impervious, anti-folding, compressive strength are steamed pressure three emptying heart open-work light-weight aseismatic insulation blocks far above the hydrophobic that solid clay brick meets national standard with volume weight.

Adopt this anti-seismic heat-preservation building blocks to build the consumption that the house has not only significantly reduced materials such as clay, sand, cement, equally also reduced workload, more guaranteed quality.Because this anti-seismic heat-preservation building blocks also has air chamber except that heat insulation cavity, so waterproof, insulation, soundproof effect are very good.Do facing if desired, the levelling of need not plastering wall of inside and outside metope can directly be constructed; Owing to cut off by the building block air chamber between wall base external surface and the insulation layer, so no matter which kind of material the exterior wall finish of doing in addition adopts can be in facing generation thermal-arrest effect.Various pipelines do not need pre-buried pipeline, directly utilize air chamber to lay and get final product.The body of wall that adopts anti-seismic heat-preservation building blocks to build by laying bricks or stones belongs to the whole shear wall structure of assembling, and there are vertical reinforcement concrete-core column and the horizontal reinforcing bar that draws of level in each building block inside, and body of wall steel concrete accounts for total body of wall 10～30%.Its characteristics one are that the reinforcing bar in stem stem and the groove has been covered with whole body of wall, reinforcement density does not have the branch of tensile region and pressure zone greatly, strength of wall body is far longer than the body of wall of the band concrete aseismatic structural column of house inner corner trim, external corner design, and building integral intensity is also greater than traditional frame construction.Traditional ordinary reinforced concrete structure stretching resistance is had a surplus, warping resistance power deficiency, what the body of wall that anti-seismic heat-preservation building blocks is built by laying bricks or stones bore all is pulling force, warping resistance power is born by the pulling force of its corresponding reinforcing bar, because tensile strength of reinforcement is far longer than its rupture strength, get final product so only need join the fine steel rib tension in the body of wall, saved the bar reinforcement consumption so greatly; The 2nd, intensive arrangement of reinforcement has been blocked irradiation of electromagnetic waves as gauze screen, has reduced the harm of electromagnetic wave to human body; The 3rd, floor adopts monobloc cast and body of wall to become one, it is stressed that body of wall is press-bending during earthquake under the earthquake horizontal force, because floor and body of wall are an integral body, total has favorable extensibility and globality, the low flexibility that has more of this body of wall and traditional shear wall resilience in comparison modulus, run into shake doughtily and have the good energy dissipation capacity of the seismic wave of absorption, the antidetonation surplus is big, anti-seismic heat-preservation building blocks and reinforcing bar acting in conjunction can reach resistance to compression, tension, bending resistance, the shearing resistance peak, meet the shockproof level of structure of " little shake is not bad; middle shake can be repaiied; no collapsing with strong earthquake ", thereby have very excellent anti-seismic performance.Because shear wall structure involves great expense, only do the basis and use the above frame construction that adopts in highrise building ± 0, common buildings employing brick mix structure at the basement of highrise building ± 0 below so China is general.Because running into the house foundation differential settlement, traditional building structure can cause the tensile region of beam, post and pressure zone variation to make wall body slit, the body of wall that adopts anti-seismic heat-preservation building blocks to build by laying bricks or stones belongs to that the whole shear wall structure of assembling runs into house foundation differential settlement body of wall and floor can not ftracture yet, so general brick mix structure need not design concrete aseismatic structural column and collar tie beam, thereby avoided the design challenges of little pier between constructional column, also reduced moment of flexure outside the plane of body of wall.Make and build in this way that the house saves time, saving of labor, laborsaving, material-saving, effective intensity height, society is acceptant.Though the polyester of high density type polyurethane hard bubbles and polymer gel material costs an arm and a leg, can construct mostly is mechanized operation, the automaticity height, with artificial few, do not have waste of raw materials,, can not surpass the master budget that common brick mixes structural thermal insulation house design-build yet so build total cost far below traditional shear wall structure and frame construction, and easy construction, good looking appearance, inexpensive, sturdy and durable; Be collection insulation, waterproof, fire prevention, sound insulation, bonding, antiseismic, flood fighting water, freeze thawing resistance, cracking resistance become, anti-aging, wind resistance is taken off, radioresistance, security performance, overall performance is all good and the later stage need not maintenance.This anti-seismic heat-preservation building blocks both had been suitable for the bearing wall of building low-rise building, also was suitable for the filled wall of building highrise building.Particularly suitable earthquake, flood disaster area rebuild.
