Abstract
The utility model discloses a composite lightweight concrete cavity building block. Thermal insulation performance of external-wall materials for buildings is of great significance to energy saving. The current technology adopted for constructing main walls mostly is to affix a heat preservation layer and a surface layer inside or outside a main wall after completing the main wall. The technology has the disadvantages of longer construction period, poorer service life of buildings and higher project cost. The composite lightweight concrete cavity building block has an 8-12 centimeters polyphony thermal insulation layer. An end of the thermal insulation layer is provided with a protruding edge equivalent to the width of joints, and cavity dead holes within lightweight concrete base material are in a staggered form, and the outer flank is provided with mortise joints connected with surfaces of external walls. And front bricks of external walls can be directly cast on the mortise joints of lightweight concrete base material. The building block increases thermal resistance, and lowers heat transfer coefficient, thus achieving the requirements of thermal insulation and saving energy. Besides, the utility model features simple construction, which secondary paste of a thermal insulation layer is not required, and shortens the construction period and lowers cost, as well as improves project quality, thus keeping the service life be in line with that of buildings.
Description
Technical field
The utility model belongs to constructional materials, particularly the composite light concrete hollow block.
Background technology
The heat-insulating property of building outer wall material is significant to energy conservation.Country has proposed to promote energy-conservation specific requirement and index of three steps.Currently used non construction technology great majority be after main body wall completion again the method at wall outer side subsides insulation layer and surface layer reach the energy-saving heat preserving requirement.Bring many inconvenience to construction like this, prolong the duration, improve construction costs.Also influence workmanship, make building not reach designing requirement, will produce " taking off skin " phenomenon in general about 25 years, overhaul also quite trouble.For addressing this problem, CN2665260Y disclosed " non-bearing heat-preserving building block for building " has solved non weight reduction and insulation problem.But do not have heat insulating material heat insulation between this product building block slit, the position of hollow blind hole does not reach evenly heat insulation requirement, does not consider the construction problem of outer wall surface yet.
Summary of the invention
In order to overcome the existing in prior technology shortcoming and defect, satisfy the requirement of building heat preserving energy conservation standard and consider the convenience of construction.The composite light concrete hollow block that the utility model is designed, form by light weight concrete construction base material, insulation layer, hollow blind hole is arranged in the middle of the light weight concrete construction base material, its characteristics are 8 to 12 centimetres of polyphenyl insulation layer thicknesses, there is the protrusion limit of suitable joint gap the insulation layer end, light weight concrete construction base material hollow core blind hole is staggered, and the joggle with the outer wall surface joggle is arranged in the outside.This joggle is interior sunk coak wide at the top and narrow at the bottom or up-narrow and down-wide protrusion tenon piece.Also facing tile directly can be cast and be contained on the light weight concrete construction base material joggle.This building block adopts polyphenyl insulation layer cost low, easy construction, and thickness reaches 8 to 12 centimetres, can satisfy the requirement of this area wall thermal insulating.There is the protrusion limit of suitable joint gap the insulation layer end, has sealed the heat transfer slit.The staggered thermal resistance that improved of light weight concrete construction base material hollow core blind hole reduces thermal transmittance, reaches the heat preservation energy-saving requirement.Have and the joggle of outer wall surface joggle or the directly building block of casting dress facing tile in the outside.Adopt this composite light concrete hollow block, construction is simple, does not need the secondary adhesive insulating layer, the reduction of erection time, reduces construction costs.Improve workmanship, it is synchronous to reach body of wall and building life-span.

The specific embodiment
Composite light concrete hollow block as shown in Figure 1, form by light weight concrete construction base material 1, insulation layer, hollow blind hole 3 is arranged in the middle of light weight concrete construction base material 1, its characteristics are 8 to 12 centimetres of polyphenyl insulation layer 2 thickness, there is the protrusion limit 4 of suitable joint gap polyphenyl insulation layer 2 ends, the hollow blind hole 3 of light weight concrete construction base material is staggered, and the joggle with the outer wall surface joggle is arranged in the outside.The protrusion limit 4 of polyphenyl insulation layer 2 ends can be that a side is protruded the suitable joint gap in limit, also can be that both sides are respectively protruded joint gap half.The joggle of light weight concrete construction base material 1 is up-narrow and down-wide protrusion tenon piece 5 or interior sunk coak 6 wide at the top and narrow at the bottom as shown in Figure 2.Can touch outer wall surface in the main body wall outside during construction, because joggle 5,6 is arranged, increase articulates performance adhering to of outer coversheet.Or use facing tile 7, can be when construction by tack coat and light weight concrete construction base material 1 tenon close, bonding.As shown in Figure 3, also facing tile 7 directly once can be cast light weight concrete construction base material 1 and polyphenyl insulation layer 2, be formed joggle with light weight concrete construction base material 1.This building block adopts polyphenyl insulation layer cost low, easy construction, and thickness reaches 8 to 12 centimetres, can satisfy this area body of wall energy-saving heat preserving requirement.There is the protrusion limit of suitable joint gap the insulation layer end, has sealed the heat transfer slit.The staggered thermal resistance that improved of light weight concrete construction base material hollow core blind hole reduces thermal transmittance, reaches the heat preservation energy-saving requirement.Construction simultaneously is simple, does not need secondary paste heat-preserving layer process, and the reduction of erection time reduces cost.Improve workmanship, it is synchronous to reach body of wall and building life-span.
