Abstract

The invention relates to a cast-in-place inorganic double-layer heat insulation wall and a construction method thereof, which belong to the technical field of building and aim to solve the defects of no concrete external wall heat insulation performance, complicated external heat insulation structure and worse firmness in combining the external wall. According to the invention, a cast-in-place heat insulation layer and an enclosing and protecting layer are arranged at the external side of the external wall in sequence. Reinforced nets are placed at the external side of the external wall; and cavity plates with T-shaped grooves at the back faces are spliced with each other to form the enclosing and protecting layer; foam concretes are injected between the concrete wall and the enclosing and protecting layer and into the T-shaped grooves of the cavity plates through a filling control hole; and the foam concrete cast at the upper layer can be also injected into gaps generated due to shrinkage in the solidification process of the foam concrete so that a double-layer heat insulation structure with integrated upper and lower parts and firmness in transverse combination is finally formed. The cast-in-place inorganic heat insulation wall provided by the invention has the advantages of good heat insulation performance, simple structure, convenience in construction and low manufacturing price.

Description

Cast-in-place inorganic double-layer heat insulation wall and construction method thereof
Technical field
The present invention relates to a kind of cast-in-place inorganic double-layer heat insulation wall and construction method thereof, belong to technical field of buildings.
Background technology
At present, the outer insulation of external wall relies on many advantages to become the principal mode of wall thermal insulation structure.Heat-insulation plate for external directly bears the impact of the natural causes such as solar radiation and ambient temperature and humidity variation, because durability and the freezing and thawing performance requirement of insulation construction to heat insulating material is higher in addition; Difficulty of construction is large, to the technical ability of construction team, requires high; Cast-in-place thermal-insulating layer and base course wall require to be connected tight, otherwise easily come off and pound and hurt sb.'s feelings; Conventional organic heat-insulating plate fireproof performance is poor, has disaster hidden-trouble.
In recent years, concrete frame structure form is applied in construction work more and more.In-situ concrete wall construction is quick and convenient, can significantly reduce Cross section Design size, improves building structure integral rigidity and stability, but itself exists the poor drawback of heat insulation property, therefore cast-in-place thermal-insulating layer must be set to reduce the transmission of heat.
Summary of the invention
The object of the invention is to solve concrete exterior wall heat-preserving performance shortcoming, overcome outer thermal insulation structure complicated and be combined the drawback such as not firm with exterior wall, a kind of cast-in-place inorganic double-layer heat insulation wall and construction method thereof that can improve architectural exterior-protecting construction globality, stability and heat-insulating property is provided.
The object of the invention is to be achieved through the following technical solutions:
A kind of cast-in-place inorganic double-layer heat insulation wall, comprise: the exterior wall between two floor floors, in the outside of exterior wall, be provided with and go along with sb. to guard him layer, at exterior wall and go along with sb. to guard him and be provided with cast-in-place cast-in-place thermal-insulating layer between layer, the described layer of going along with sb. to guard him is for the assembled formation of cavity plate, and described cast-in-place cast-in-place thermal-insulating layer is foam concrete layer of concrete.
A construction method for cast-in-place inorganic double-layer heat insulation wall, it comprises following operation:
A. first construction forms the exterior wall between floor and upper and lower floor, and makes floor outwards choose exterior wall, and the perfusion control hole that runs through floor is set on floor, then arranges reinforcing mat in the outside of exterior wall, and carry out following construction from bottom to top,
B. in the outside of current layer exterior wall, with the cavity plate construction that the back side is provided with T-slot, go along with sb. to guard him layer, and make exterior wall and go along with sb. to guard him the gap of leaving cast-in-place cast-in-situ thermal-insulated layer thickness size between layer,
C. by the perfusion control hole of current layer roof, foam concrete poured into the exterior wall of current layer and go along with sb. to guard him the gap between layer and foam concrete is inserted in the T-slot of cavity plate, after foam concrete solidifies, entering step D,
D. at the last layer repeating step A of current layer, B, setting completed to the perfusion control hole at last layer top for C, by the perfusion control hole of last layer roof, foam concrete is poured into the exterior wall of last layer and go along with sb. to guard him in the gap between layer, and make foam concrete by the perfusion control hole of current layer roof, enter and fill in the cast-in-place thermal-insulating layer of current layer because shrinking the space producing in foam concrete process of setting
E. last layer is set to current layer, repeating step D, until construct to top layer.
The present invention has the following advantages:
(1) foam concrete is effectively in the T-slot of cavity filling plate, make to go along with sb. to guard him layer and closely connect into entirety with exterior wall, strengthened the stability of going along with sb. to guard him layer, the hollow structure of cavity plate and foam concrete form economic benefits and social benefits cast-in-place thermal-insulating layer, have made up well the poor deficiency of external wall body thermal insulation heat-proof quality.
(2) when the insulation layer of a upper floor is built, foam concrete can flow in the cast-in-place thermal-insulating layer of lower floor's body of wall by running through the perfusion control hole of floor, the space producing because of contraction to fill up the foam concrete of lower floor's body of wall cast-in-place thermal-insulating layer, thereby upper and lower insulation layer is connected, has improved heat insulation effect.
(3) go along with sb. to guard him layer and make cast-in-place thermal-insulating layer be subject to the strength decreased of factor of natural environment effect, cast-in-place thermal-insulating layer has been played to good protection and decoration function, can extend heat insulating material application life.What go along with sb. to guard him layer and cast-in-place thermal-insulating layer employing is all non-combustible materials, has eliminated disaster hidden-trouble.
(4) going along with sb. to guard him layer cavity plate used is easy to by industrial standardization production moulding, can make the bulk board logical high with floor and splice by the size of a face wall in scene, then use facility lifting, also can carry out compound with ornament materials simultaneously, can accomplish to go along with sb. to guard him, insulation and decoration integrated, reduce working procedure, reduce construction costs.
