A kind of composite thermal self-insulation building block
Technical field
This utility model relates to a kind of composite thermal self-insulation building block for building energy saving building exterior wall by laying bricks or stones.
Background technology
At present, in the architectural engineering of China, utilize body of wall energy-conservation and structure-integrated technology has more advantage than outside wall heat preservation in tradition.During application External Walls Heating Insulation, primarily serve energy-conservation, elimination heat bridge effect and the effect of protection exterior wall.External Walls Heating Insulation played an important role in the building trade of China, becomes one of most important link in architectural engineering, but the External Walls Heating Insulation of China is still in primary research and development and trial period.Therefore, during the use of External Walls Heating Insulation, there is also certain problem.
As a example by external hanging type outside wall heat preservation, during external hanging type outside wall heat preservation is constructed with the exterior-wall heat insulation being widely used in architectural engineering, during the use of this technology, need use special fixture or cohere mortar, although heat insulation effect is good, but in use the technology of construction is required higher, be easily subject to the impact of anthropic factor, and then affect the construction period, it is unfavorable for ensureing the safety of workmen.
Complex heat-preservation technology, it is common that be combined by the construction materials such as insulation material and concrete, forms the Constracture unit with heat insulation effect.Existing composite thermal self-insulation building block is typically to add the heat-insulation layer of the materials such as EPS in building block, forms three-decker, existing heat-insulating property, there is again building block building attribute originally.Patent CN204299026U discloses a kind of heat insulation building block, and this building block includes a warming plate and two cement board, utilizes the body of wall of this concrete block masonry to have heat insulation effect, it is not necessary to carry out plug-in insulation again.Patent CN204510594U discloses one and meets building block, accompanies heat-insulation layer in building block body, and after combination, connecting portion does not the most exist heat bridge, improves the integral heat insulation effect of building block.
But above-mentioned technology does not the most solve the stability problem of building block, due to the attribute difference of building block layer material Yu heat-insulation layer material, there is the problem combining instability, easily produce the problem that building block layer comes off from heat-insulation layer in the two during combining to a great extent.The contact surface by building block layer Yu heat-insulation layer that prior art has is processed into concaveconvex structure, increases contact area, but does not tackle the problem at its root, and therefore, now needs a kind of building block badly, had both had heat-insulating property, and had again stability and standard concurrently.
Utility model content
The purpose of this utility model is to provide a kind of high insulating effect, and stability is high, the composite thermal self-insulation building block of good integrity.
The technical solution of the utility model is:
A kind of composite thermal self-insulation building block, including the upper outer coversheet being combined with each other the most successively, heat-insulation layer and lower outer coversheet, the both sides of described heat-insulation layer are interval with groove, the upper outer coversheet of building block and lower outer coversheet are respectively equipped with, on the joint face of heat-insulation layer, the projection matched with heat-insulation layer, described heat-insulation layer is provided with the hole running through two sides, the material identical with upper outer coversheet and lower outer coversheet, upper outer coversheet, hole and the one slurry molding of lower outer coversheet it is filled with in hole.
Hole forms pulling plug structure between upper and lower outer coversheet, can be effectively improved the stability of building block, prevent structure sheaf from separating with heat-insulation layer, reduces the risk that comes off.
The material that described upper outer coversheet, lower outer coversheet and hole are used is foamed concrete or lightweight concrete.The sectional area of described hole is 1/100-1/20 with the ratio of the gross area of building block monomer.Structure sheaf uses foamed concrete or lightweight concrete material, relative to traditional materials such as cement, having firm, the advantage of light weight, the sectional area of hole arranges the coordination having accomplished heat insulating ability with stability, sectional area is excessive is unfavorable for insulation, and the drawknot effect of too small hole is not enough.
Described block interiors is evenly arranged with dowel, and dowel extends vertically through in heat-insulation layer, and the two ends of dowel lay respectively at inside and the inside of lower outer coversheet of outer coversheet.The 5/6-11/12 of a length of composite thermal self-insulation building block thickness of described dowel.Described dowel is any one in reinforcing bar, anticorrosion bamboo let, anticorrosion peg wood.For further enhancing the stability of building block, in building block in addition to arranging coupling bar, it is also possible to arrange dowel, the two ends of dowel lay respectively at inside and the inside of lower outer coversheet of outer coversheet, and the outer surface of two ends distance building block leaves the overcoat of 1-2cm.
The wherein preferred Ribbed Bar of reinforcing bar, the helicitic texture on Ribbed Bar surface is conducive to the contact area improving reinforcing bar with structure sheaf, strengthens draw knot force.
The plucking on the joint face of interface agent layer, described extruded sheet and upper outer coversheet and lower outer coversheet with mao spike, a length of 3-5mm of described plucking it is brushed with on the joint face of heat-insulation layer and upper outer coversheet and lower outer coversheet.Wharf's pavement quality has two ways, one is to pat at metope by interfacial agents, warming plate surface forms salient point one by one, another kind of method is to utilize artificial or machine mode to mark hairy projection on warming plate, two ways can be used in combination, and effect is all to strengthen the attachment force between different materials, owing to extruded sheet is different with the character of styrofoam, extruded sheet can use cutting machine to carry out plucking, and the plucking mode of styrofoam is mainly interfacial agents.
The material that described heat-insulation layer is used is any one in EPS, SEPS, XPS material.The material of heat-insulation layer has various selection, and including styrofoam EPS, graphite polystyrene board SEPS, and extruded sheet XPS, preferably graphite polystyrene board, graphite polystyrene board has insulation and fire-proof function concurrently.
This utility model has the advantage that with good effect: owing to using technique scheme, building block of the present utility model has high insulating effect, and stability is high, the advantage of good integrity.
