Description
Technical field
The utility model belongs to constructional materials, is mainly used in construction work external wall construction.
Background technology
In order to make building have good fireproof performance, heat-insulating property and exterior surface of wall feature elegant in appearance, especially meet the thermal requirements in north cold area, numerous buildings all arranges insulation construction on its exterior wall surface.
At present, insulation construction is generally after air-entrained concrete building block used for building exterior wall has been built by laying bricks or stones, polyphenyl plate or extruded sheet are pasted onto on exterior wall, be coated with one deck anticracking grout again, grid cloth paving is bonded on anticracking grout face, then followed closely on exterior wall with special nail, and then be coated with one deck anticracking grout, finally carried out incrustation process.But this conventional insulation construction material therefor only can meet heat-insulating property, but fire protection flame retarding, wall integrity and weatherability are poor, and working procedure is many and miscellaneous, and cause the construction period long, construction cost is high, the shortcoming that construction safety coefficient is low.
Summary of the invention
the utility model provides good heat insulating, long service life and construction cost is low, can avoid that wall insulating layer comes off, the concrete self-insulating composite block of problem of Cracking.
Concrete self-insulating composite block
,connect pin by concrete main body building block, external thermal insulation, heat-preserving core, concrete cover and concrete to form.
Described concrete main body building block is made up of upper plate, lower plate (build by laying bricks or stones and refer to inner side of outer wall on body of wall), junction plate and four joint pins, and upper plate is connected by joint pin with four angles of lower plate, and upper plate is connected by junction plate with the centre of lower plate;
Described heat-preserving core is filled in the cavity of described concrete main body building block; External thermal insulation is provided with above concrete main body building block; Concrete cover (build by laying bricks or stones and refer to outside exterior wall on body of wall) is provided with above external thermal insulation; Be connected with concrete between concrete cover, external thermal insulation with concrete main body building block and be connected pin; Concrete connects in pin has built steel wire.
The unit weight (kg/m3) of composite self-heat-insulation concrete building block (the present invention) is 400-500; Cubic compressive strength (MPa) is 6; Coefficient of thermal conductivity (W/ (mK)) is 0.064; Sound insulation coefficient DB is 45-50; Dry contraction mm/m is 0.16; Moisture content (mass percent) is 5%; Saturated water absorption (mass percent) is 29%; Heat insulation pattern and the scope of application are heat insulation without cold-heat bridge, composite wall structure, are applicable to entirely to cut, framework, building with brick-concrete structure; Binding type and the durability of plastering is the same life-span with building, and good endurance, bonds with floated coat, and metope ftractures without hollowing.
The unit weight (kg/m3) of Autoclaved aerated concrete blocks is 500-700; Cubic compressive strength (MPa) is 3-5; Coefficient of thermal conductivity (W/ (mK)) is 0.2-0.22; Sound insulation coefficient DB is 45-55; Dry contraction mm/m is 0.8; Moisture content (mass percent) is 6-10%; Saturated water absorption (mass percent) is 60-70%; Heat insulation pattern and the scope of application have cold-heat bridge, without sheet material advantage, only fills for framework; Binding type and the durability of plastering is non-caked with floated coat, needs specially treated, the easy hollowing cracking of metope.
The unit weight (kg/m3) of outer heat preservation system is light; Cubic compressive strength (MPa) is minimum; Coefficient of thermal conductivity (W/ (mK)) is 0.045; Nothing without sound insulation coefficient DB; Dry contraction mm/m is large; Without moisture content; Without saturated water absorption; Heat insulation pattern and the scope of application are heat insulation without cold-heat bridge, composite wall structure, are applicable to entirely to cut, framework, building with brick-concrete structure; Binding type and the durability of plastering is the easy hollowing cracking of durability extreme difference metope.
The present invention also has following advantage:
1, building block inside and outside wall, topping: the concrete that material is is aggregate with building waste, microlith; give building block: high-strength, low air shrinkage value, low water absorption, low-water-content and excellent anti-freezing property, good secondary workability, for the hanging of decoration construction and sanitaryware provides solid metope.Increase the heat inertia index of masonry, improve indoor thermal environment quality, improve the comfortableness of inhabitation human body.
2, building block external thermal insulation, filling heat insulating wall: EPS heat insulating material is filled in the cavity of concrete support, and self does not bear any active force.Its unit weight does not require>=18 ㎏/m by secondary heat preserving mode
3; Gauze wire cloth frame plate requires>=15 ㎏/m
3; Restriction.When there being special fire protection requirement, mineral wool board can be selected.
3, the hanging of masonry wall pipeline box and sanitaryware, air-conditioning etc. is reliably easy: according to design corresponding drawing defoam, can in body of wall multi-direction layout pipeline; After relatively solid metope perforate, insert clay after a small amount of foam around taking out, switch enclosure or the suspender member such as sanitaryware, air-conditioning can be buried underground in clay, solid and reliable.
4, fireproof performance
(1) the concrete frame structure of heat insulation building block itself is A level fireproof overall structure, and B1 level EPS heat insulating material is filled in the cavity of tectonic system, belongs to Self-thermal-insulation System.
Heat insulating material is filled in the cavity of concrete support, and when building by laying bricks or stones, it contacts with masonry mortar, without disaster hidden-trouble; After becoming wall, EPS heat insulating material is sealed in the thick concrete cover of >25-30mm, do not have the environment burnt, also without the approach lighted.
(2) when there being special fire protection requirement, heat insulating material can select mineral wool board, block of glass wool.
