Abstract
The utility model belongs to a bearing-type cast-in-place insulating layer outer wall. The wall is composed of bearing-type hollow building blocks used for building and insulating layers arranged in the hollow blocks in a cast-in-place mode. The bearing-type hollow blocks are building bodies formed through building block outer wall face layers integrally connected with building block connecting ribs Insulating layer casting space is arranged between the hollow building blocks and the building block outer wall face layers. According to the wall, in the building construction of the bearing-type building blocks, the polyurethane foaming insulating layers are arranged in the cast-in-place mode, so that the built outer wall insulating layers and the building block outer wall face layers firmly adhere to be of an integrated structure in the process of foaming. Therefore, the heat bridge phenomenon or the cold bridge phenomenon generated by mortar joints can be effectively eliminated for the wall, and the bearing-type cast-in-place insulating layer outer wall has the advantages of being good in heat preservation, heat insulation and sound insulation effect and not prone to cracking, water seepage and falling, so that comprehensive cost is reduced.
Description
Technical field
The utility model belongs to Building architecture technical field, is specifically related to a kind of bearing type cast-in-place thermal-insulating layer exterior wall.
Background technology
Building energy conservation wall thermal insulating is commonplace at present, but heat preservation energy-saving system has different drawbacks, although adopt cystosepiment heat insulation system heat preservation energy-saving can reach requirement, its complex process, application life is short, inflammable, dangerous, uneconomical, later period maintenance maintenance cost is large; Although adopt rock cotton board to belong to inorganic non-combustible material, its cost is high, and also defectiveness of the aspect such as application life; At the operable heat preservation slurry in Xia Redong cryogenic region, because its used thickness is large, cost is high, easily produce potential safety hazard.Existing bearing type composite heat insulation block for building on market, conventionally adopt batch production to make, because the insulation layer in building block is also that the monolithic the same with building block forms, after building wall, between building block and building block, leave mortar joint, not integrative-structure, easily produce " heat bridge " or " cold bridge ", cause the loss of energy, therefore, heat insulation effect does not reach national energy-saving standard-required.
Utility model content
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, provide a kind of insulating layer of external wall of building and body of wall of making to become one structure, and can meet national energy-saving requirement, reach easy construction, reduction of erection time, saving cost, bearing type cast-in-place thermal-insulating layer body of wall that integrated cost is low.
Realizing the technical scheme that the purpose of this utility model takes is, this body of wall is to consist of bearing type hollow blocks built and cast-in-place insulation layer in building block, wherein, bearing type building-block is by the masonry of the building block outer wall surface formation of building block dowel one connection, between building-block and building block outer wall surface, is provided with insulation layer casting space.
The cast-in-place compound that is filled with hard polyurethane foam expanded material or polyurethane rigid foam material and granular polystyrene material in described insulation layer casting space.
Described bearing type building-block is concrete products.
The bearing type cast-in-place thermal-insulating layer exterior wall of making according to such scheme, can be in load bearing hollow block building construction, cast-in-site polyurethane foamed thermal-insulating layer, makes insulating layer of external wall and the building block outer wall surface of building by laying bricks or stones firmly be bonded to and be structure as a whole in foaming process.And the technique of this cast in situs polyurethane foam is simple, can save 50% expense, its duration is short, cost is low, economic, practical, safety.This body of wall by adopting cast-in-place hard polyurethane foam expanded material in body of wall, can increase the intensity of whole exterior wall, and can effectively eliminate " heat bridge " or " cold bridge " phenomenon that body of wall produces due to mortar joint, insulation, heat insulation, effective, the hardship that can remove later maintenance engineering and maintenance simultaneously from.Significantly reduced thus integrated cost.Compared with prior art, this body of wall have that bulk strength is high, simple process, saving of work and time, the duration is short, the life-span is long, insulation, heat insulation, sound insulation, good water-proof effect and not easy to crack, the feature such as come off.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, bearing type cast-in-place thermal-insulating layer exterior wall of the present utility model, this body of wall is to be built by laying bricks or stones with cast-in-place insulation layer 4 in building block and formed by bearing type building-block 1, wherein, bearing type building-block 1 is by the masonry of building block outer wall surface 3 formations of building block dowel 2 one connections, between building-block 1 and building block outer wall surface 3, is provided with insulation layer casting space.In insulation layer casting space, cast-in-site is filled with the compound of hard polyurethane foam expanded material or polyurethane rigid foam material and granular polystyrene material, wherein, the mixed proportion of polyurethane rigid foam material and granular polystyrene material is rigid polyurethane foam material ︰ granular polystyrene material=1 ︰ 0.3～1 by weight.Described bearing type building-block 1 is concrete products.When construction, first with building-block 1, carry out building by laying bricks or stones of body of wall, when building 3～5 layers by laying bricks or stones, just can carry out cast-in-site polyurethane foam material at the heat insulating material casting space arranging, make the insulating layer of external wall 4 of building by laying bricks or stones firmly be bonded to and be structure as a whole in foaming process with building block outer wall surface 3.When adopting the compound of polyurethane rigid foam material and granular polystyrene material, in watering the process of post polyurethane rigid foam material, according to the ratio of described weight proportion, directly granular polystyrene material is joined in the polyurethane rigid foam material that waters post, granular polystyrene material is under liquid foaming material effect, together dissolving cured.In this case, the polyurethane rigid foam material of filling in building block, is net structure, belong to cross-linked thermal set resin foam, be a kind of high score thermosetting polymer, there is nontoxic, corrosion-resistant, high-low temperature resistant and resistance to compression, tensile strength is large, Stability Analysis of Structures, anti-aging, the features such as long service life.Because polyurethane rigid foam material has unique hole-closing structure, rate of closed hole reaches more than 90%, its coefficient of thermal conductivity is generally between 0.017～0.022W/MK, therefore, the heat insulation and preservation effect of this material is good, energy-saving efficiency is high, and this material also has not moisture, water absorption rate is low, there is high water vapor permeable barrier, good impermeability and larger pliability and the strong characteristic of opposing external force variations in temperature ability, its heat stability can be up to 120 ℃, therefore, under summer high temperature state, hard polyurethane foam insulation layer is difficult for producing deformation, bending phenomenon, can thus be exterior insulation work cracking resistance, impervious water, anti-coming off provides good basic guarantee, thereby effectively improve the overall security of building.
