Description
Technical field
The invention belongs to the energy-saving building materials technical field, be specifically related to a kind of composite type modified steel reinforced concrete self-insulating wall material and preparation method thereof.
Background technology
Along with Chinese economic development, external wall energy-conservation required increasingly high.According to relevant regulations: the external wall energy-saving of public Class A building requires mean thermal transmittance to reach 0.7W/ (m
2.K) below; The external wall energy-saving of public Class B building requires mean thermal transmittance to reach 1W/ (m
2.K) below; The external wall energy-saving of public Class C building requires mean thermal transmittance to reach 1.5W/ (m
2.K) below; The external wall energy-saving of the building of residential houses requires mean thermal transmittance to reach 1.5W/ (m
2.K) below.For satisfying the building energy conservation requirement, at present, the main method of external wall energy-saving is to increase insulation layer at wall face; This method has not only increased working procedure, has increased a large amount of labour costs, and the application life of insulation layer is shorter; Cause fire easily, cause security incident.
Summary of the invention
The invention provides a kind of energy-conservation requirement of external wall of building and suitability for industrialized production composite type modified steel reinforced concrete self-insulating wall material that can satisfy all kinds of buildings.
The invention provides a kind of composite type modified steel reinforced concrete self-insulating wall material; Comprise upper strata modified concrete layer, lower floor's modified concrete layer and intermediate layer sandwich thermal insulation board; It is characterized in that; Be provided with the top mat sheet in the modified concrete layer of described upper strata, be provided with lower floor's reinforced mesh in lower floor's modified concrete layer; The intermediate layer sandwich thermal insulation board is provided with connecting hole, is installed with reinforcing bar in the connecting hole; Upper strata modified concrete layer, intermediate layer sandwich thermal insulation board and lower floor's modified concrete layer fuse through the modified steel reinforced concrete that forms in the connecting hole; Be provided with the frame reinforced concrete beam of the sealing of being made up of frame reinforcing bar and the modified concrete of building around lower floor's reinforced mesh and the top mat sheet, frame reinforced concrete beam one side is equipped with hoisting ring.
Described lower floor reinforced mesh has the crotch that can hold the frame reinforcing bar.
The bar gauge that the present invention adopted comprises: the frame reinforcing bar is selected from
screw thread or
reinforcing bar, can adjust as required; Top mat sheet and lower floor's reinforced mesh are selected from
reinforcing bar; Reinforcing bar is selected from
reinforcing bar in the connecting hole, can adjust as required in the practical application.
The adoptable hoisting ring specification of the present invention is at least
hoisting ring, can adjust as required in the practical application.
The frame reinforced concrete beam cross-sectional height of sealing according to the invention is: 160-300mm, width is: 60-200mm.
The present invention takes all factors into consideration heat-insulating property and manufacturing cost, the sandwich thermal insulated plate thickness 40-180mm in described intermediate layer.The intermediate layer sandwich thermal insulation board is too thick, can increase preparation cost, and middle sandwich thermal insulation board is too thin then not to have good heat preservation and energy conservation effects.
The present invention takes all factors into consideration whole walling heat transfer property and requirement of strength, and the thickness of described upper strata modified concrete layer and lower floor's modified concrete layer is 40-100mm.If upper strata modified concrete layer and lower floor's modified concrete layer are too thick, the thermal transmittance of walling will increase, and energy-saving effect reduces; If upper strata modified concrete layer and lower floor's modified concrete layer are too thin, then do not reach the building requirement of strength.
Described modified concrete, wherein cement: sand: rubble: the volume ratio of foam beads is 1: 1.5-2: 2-2.4: 0.6, and weight ratio is: 1: 1.5-2: 2-2.4: 0.003-0.008, can mix Admixture and flyash simultaneously, intensity can reach more than the C20.
Described foam beads is haydite or polyphenyl expanded beads.Adding foam beads mainly is to reduce concrete coefficient of thermal conductivity.The addition of foam beads can not be too big, and too conference makes concrete intensity not reach requirement.
Described frame reinforcing bar horizontal direction is stretched out vertical direction edge 200-300mm, uses with frame column is whole and waters or on the frame reinforced concrete beam of vertical direction, establish pre-buried steel part, is used for and the post welding of having watered.
A plurality of connecting holes that evenly distribute on the described sandwich thermal insulation board, the connecting hole pore size can be adjusted as required, is used for guaranteeing the integral rigidity of whole walling, guarantees to produce, transportation, intact when installing.
The preparation method of described composite type modified steel reinforced concrete self-insulating wall material comprises: size by drawing prepares framed, puts into lower floor's reinforced mesh and frame reinforcing bar; Preheating embedding line is put into hoisting ring then, and hoisting ring is connected with the frame reinforcing bar; Build lower floor's modified concrete layer, put into the intermediate layer sandwich thermal insulation board, in the tie point hole, put into connecting reinforcement; Put into the top mat sheet, build upper strata modification coagulating layer soil layer, maintenance; Remove framedly, process composite type modified steel reinforced concrete self-insulating wall material.
The beneficial effect that the present invention obtained is:
(1) composite type modified steel reinforced concrete self-insulating wall material of the present invention adopts the reinforced concrete beam of four limits for sealing, no disaster hidden-trouble, and guaranteed the integral rigidity of walling.
(2) composite type modified steel reinforced concrete self-insulating wall material of the present invention, on-the-spot easy for installation, can water or weld with frame column is whole again by first wall plate with the post that has watered.
(3) composite type modified steel reinforced concrete self-insulating wall material of the present invention, employing be the mode of evenly arranging a plurality of tie points, can reduce the heat transfer of steel concrete rib in the walling, guarantee the integral rigidity of walling simultaneously.
(4) composite type modified steel reinforced concrete self-insulating wall material of the present invention has adopted the sandwich thermal insulated sheet material in intermediate layer, in insulation, has reduced the overall weight of walling, makes it easy for installation.
(5) composite type modified steel reinforced concrete self-insulating wall material of the present invention has adopted modified concrete, thus with the coefficient of thermal conductivity of steel concrete by existing 1.74W/ (m.K), reduce to below the 1.4W/ (m.K).
(6) composite type modified steel reinforced concrete self-insulating wall material of the present invention must not whitewash, and can when making, arrange good concreting again to exposed wall facing brick earlier, and facing and wallboard are made and once accomplished; Concrete size can be adjusted flexibly; Also can make energy-conservation floor uses.
