Description

A kind of bridge cut-off self-heat conserving infilled wall for building

Technical field

The utility model relates to a kind of construction wall, is specially a kind of bridge cut-off self-heat conserving infilled wall for building.

Background technology

Along with carrying out of China's energy saving policy, building energy conservation is also proposed to higher requirement.In building construction process, carried out energetically at present External Thermal Insulation Technology for External, but current thermal insulation system engineering, mostly rest on the body of wall basis of having completed, take in addition the way of secondary insulation, like this, one side long construction period, prior reason is to have increased building costs in addition, how to develop and integrate multi-functional, and to remove the working procedure of doing again secondary insulation from be the starting point of this programme.Heat insulating material conventional in engineering adopts extruded sheet more, polyphenyl plate, and rock cotton board, phenolic board, fly ash building block etc., product category is abundanter, but extruded sheet, phenolic board fireproof performance are poor, during construction cutting, easily produce the spittle, and contaminated environment, impact are breathed; Rock cotton board water imbibition is poor, during construction cutting, easily produces the short fiber spittle, contaminated environment, difficult construction.And these products are all more difficult aspect quality control, some material, application life is short, can not with the same life-span of building.

Infilled wall is with building blocks such as fly ash aerated, hollow brick in the market, if reach national 65% energy conservation standard, just must increase its thickness or do secondary insulation, can increase load to building like this, and affect building effective area, increase building costs, and construction period extends.And in the market steel wire net rack sandwich partition wall of the same type owing to all having adopted common galvanized steel wire netting to support and two-sided enclosed structure as skeleton, the coefficient of thermal conductivity of steel wire is 80W/mK, coefficient of thermal conductivity is high, and have a strong impact on heat insulating effect, not even as the heat insulating effect of common brick wall.In addition, between zinc-coated wire in the molding polyphenyl plate galvanized steel wire netting sheet surperficial with it, use spot welding to be connected, common spot welding is because production, transportation, on-site cutting are easy to cause weld sealing-off, have a strong impact on production efficiency and efficiency of construction, and some sandwiched plates is while adopting as organic materials such as polyphenyl plate, have disaster hidden-trouble, and sandwich inner frame is not continuous triangle shape, shock resistance is poor, can not meet exterior wall instructions for use.The partition wall of other types is as excessive in GRC plate, hollow cement board, deadweight, and compressive strength is low, and heat preservation and soundproof poor performance can not effectively improve Antiseismic building performance.All do not meet national energy-saving environmental protection policy.

Summary of the invention

In order to solve, existing building is high with infilled wall coefficient of thermal conductivity, heat insulating effect is poor, skeleton connection is unreliable for the utility model, need the problems such as increase secondary insulation construction, provides a kind of bridge cut-off self-heat conserving infilled wall for building.

The utility model is realized by the following technical solutions: a kind of bridge cut-off self-heat conserving infilled wall for building, comprise inner side layer of concrete, outside layer of concrete and be coated on the steel wire net rack thermal insulation clamp sandwich layer between inner side layer of concrete and outside layer of concrete, described steel wire net rack thermal insulation clamp sandwich layer contains expanded perlite sandwich, be set up on expanded perlite sandwich, the in-core skeleton of the steel fabric sheet of soffit and some insert continually expanded perlite sandwiches, expanded perlite sandwich is stretched out at in-core skeleton two ends, and end is connected with in-core skeleton respectively, innovative point of the present utility model is that described steel fabric sheet adopts PVC plastic coating steel wire to make.Described PVC plastic coating steel wire is existing well known materials, there is good mechanical property, abrasion resistance and outstanding rotproofness, application life is longer, the more important thing is that the steel fabric sheet that adopts PVC plastic coating steel wire to make can effectively stop heat transfer effect, reduce the thermal transmittance of heat-preserving wall, and anticorrosive, antiageing effect is better.

In order to optimize the structure of this infilled wall, improve its function, the utility model has also carried out following structure design:

Described in-core skeleton is V-shaped, and adopts PVC plastic coating steel wire to make, and the utility model adopts V-type PVC plastic coating steel wire to replace common V-type zinc-coated wire to do bridge cut-off and processes, can further stop infilled wall heat transfer effect, reduce the thermal transmittance of body of wall, and anticorrosive, and antiageing effect is better.

Between described in-core skeleton two ends and steel fabric sheet, adopt U-shaped metal card or C type metal card to be connected.Described U-shaped metal card or C type metal card are existing known products, its structure and using method are known for the public, and this kind of connected mode replaces spot welding to connect for the utility model, can site operation convenient, increase work efficiency, also can avoid the existing problems of spot welding.

Compared with prior art, the utility model is simple in structure, reasonable in design, easy to make, good effect of heat insulation, removed the working procedure of doing secondary insulation on existing body of wall basis from, solve the problem that existing infilled wall metallic framework heat is transmitted, improved partition wall heat insulation effect of heat insulation, improved Antiseismic building performance, reduce building costs, shorten construction period, increase effective area, the most important thing is to actively push forward national green building, industrialization of construction industry development.
