Embodiment 1

[0021] The insulation boards (2, 6, 6') used in the present invention are polystyrene foam boards.

[0022] Such as Figure 1 ~ Figure 3 As shown, a thermal insulation and energy-saving block is made of 230 kg of 42.5 ordinary Portland cement, cement as the cementitious material, and 750 kg of various light aggregates (that is, 500 kg of industrial waste slag, 30 kg of waste bricks) Slag, 100 kilograms of ceramsite, 50 kilograms of perlite, 70 kilograms of hard shell waste polyphenylene particles, etc.) are used as filling aggregates, mixed with 18 kilograms of mortar anti-cracking and shrinkage reduction external admixtures and 2 kilograms of sodium dodecylbenzenesulfonate, The fluidized lightweight concrete with excellent thermal performance is mixed with water, and then it is formed by one-time pouring through the special group mold (ZL02254811.4) and the polystyrene foam board as a whole without gaps. The thermal insulation board 2 is in the shape of a "Z" in the section ...

Embodiment 2

[0025] During the pre-laying construction in the shear wall formwork, when the formwork is poured to support the shear wall 7, the concrete support eaves 8 are made layer by layer when the shear wall is poured, and are attached to the outer formwork, and the heat-insulating and energy-saving blocks 1 are pre-built with mortar , the shear wall pouring formwork and the block 1 are tensioned by the tensioned steel bars 9 . The ends of the supporting eaves 8 are filled with polystyrene foam boards. After the masonry is completed, the steel bars are bound, and the formwork on the other side is supported to construct the main body of the shear wall. After completion, the heat-insulating and energy-saving blocks and the main body of the shear wall form a compact composite insulation wall structure, and the cement mortar is plastered and whitewashed.

Embodiment 3

[0027] During the external insulation construction of the building wall of the brick-concrete structure system, the concrete support eaves 8 are made when the brick-concrete structure is built, and the ends of the support eaves 8 are filled with polystyrene foam boards. On the support eaves 8, 24 brick wall load-bearing 600X300X120 heat-insulating and energy-saving blocks 1 are used as the form of external heat preservation. When building masonry, bricks and blocks are used to match the inside and outside of the support eaves 8. The height of the support eaves 8 and the tensioned steel bars 9 is 600mm , 24 brick walls 10 and blocks 1 are tensioned by tensioning steel bars 9 to form a composite masonry structure outside the blocks inside the bricks, which meets the load-bearing requirements and achieves the effect of heat preservation and energy saving, and is plastered with cement mortar.

Abstract

The present invention relates to a construction method for a heat-preservation adiabatic energy-saving building block off a shear wall. The building block is through adopting the following steps that: cement and various light aggregates are mixed with a mortar anti-cracking shrinkage exosmotic agent and a powder foaming foam stabilizer to make light concrete; and then the building block is made through the gapless tight composite one-step pouring forming. The heat-preservation adiabatic energy-saving building block is used in construction modes including shear wall gluing building, shear wall template inner prebuilding, mixed match building and frame filling to form the outer heat-preservation protective layers, the inner heat-preservation protective layers and the self heat-preservation protective layers of building wall bodies of various structural systems; moreover, the building block eliminates self cold / thermal bridge phenomenon and increases the quality and the effect of a building heat-preservation engineering.

Description

technical field [0001] The invention relates to a construction method of a heat-insulating and energy-saving block for external heat preservation of a shear wall. Background technique [0002] At present, my country is in the heyday of construction industry development. From 1990 to 2002, the average annual growth rate of the building area under construction and completion in my country was as high as 155%. With the rapid growth of the building area, the country's requirements for building materials continue to increase. That is to say, light weight, high strength, but also energy saving and heat preservation. The Chinese patent discloses a "multifunctional composite building block". Although the block integrates the functions of enclosure and decoration, it also has the excellent performances of energy saving, heat preservation and heat insulation. However, the concrete on the left and right sides of the block fails to solve the technical problem of "cold (hot) bridge" ...
