Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As Figure 1-3, a kind of heat preservation decoration integrative composite concrete prefabricated units, comprise decorative wall face brick 5 and prefabricated portion, described decorative wall face brick 5 is consolidated into an entirety with prefabricated portion by bonding mortar layer 6, described prefabricated portion is the cracking resistance surface layer 1 be made up of anticracking grout compound successively, the not stratified composite construction of the insulation layer 2 that thermal insulation mortar compound is made and layer of concrete 3 consolidation that concrete mortar compound is made, described bonding mortar layer 6 and cracking resistance surface layer 1 consolidation, described layer of concrete 3 comprises fill concrete 31, skeleton 32 and built-in fitting, described skeleton 32 extends in insulation layer 2.
The outermost layer of these prefabricated units is decorative wall face bricks 5, the shape of decorative wall face brick 5 and structure require to arrange according to actual design, generally can adopt decorative wall face brick 5 described in polylith connect arrangement shaping, in order to decorative wall face brick 5 is better combined with prefabricated portion, prevent any packaged decorations walltile 5 from departing from, need to strengthen the connection between decorative wall face brick 5, therefore it is bonding by adhesive tape 51 between adjacent decoration walltile 5, decorative wall face brick 5 links together by adhesive tape 51, and is consolidated by bonding mortar layer 6 and prefabricated component.Adhesive tape 51 can adopt any material of the bonding decorative wall face brick 5 of energy, and the present invention is not construed as limiting.
Bonding mortar layer 6 is for bonding together decorative wall face brick 5 with prefabricated portion, bonding mortar layer 6 adopts bonding mortar compound to make, and has stronger adhesive property, can strong bond decorative wall face brick 5, and having good compatibility with cracking resistance surface layer 1, the two can reliably be consolidated.
Prefabricated portion comprises cracking resistance surface layer 1, insulation layer 2 and layer of concrete 3.
Cracking resistance surface layer 1 is in the face of the first floor structure of environment, its emphasis will have higher weatherability, reduce or avoid because environmental change forms the phenomenon such as cause cracking, come off of expanding with heat and contract with cold, cracking resistance surface layer 1 is not easily blocked up, difference of expanding with heat and contract with cold inside and outside making and ftractureing, the thickness of general described cracking resistance surface layer 1 is 3-6mm.
The shape of insulation layer 2 and thickness are selected to be need to reach certain thermal requirements, and the present invention is not construed as limiting, and insulation layer 2 thickness of the present invention is preferably 30-40mm, can reach heat insulation effect within the scope of this, without the need to thicker insulation layer 2.
Layer of concrete 3 is last Rotating fields, and be the supporting part of whole prefabricated units, its shape and thickness, according to Architectural Design Requirements, are not limited in any way at this.Because insulation layer 2 is in plastic state, then when arranging cage of reinforcement 32, can be embedded in insulation layer 2 by the end of the cage of reinforcement 32 near insulation layer 2, described skeleton 32 extends in insulation layer 2, can strengthen the adhesion between insulation layer 2 and layer of concrete 3.
In prefabricated units manufacture process, building for every layer is all reaching under plastic state or just build lower one deck after one deck before building at once, then two top layers of adjacent layer are just bonded together into as a whole, do not form sharp interface.Namely between described bonding mortar layer 6, cracking resistance surface layer 1, insulation layer 2, layer of concrete 3, junction is fused into not stratified entirety mutually.Particularly insulation layer 2 is built, and owing to having light heat insulation material in thermal insulation mortar compound, overall light weight, can wait until that cracking resistance surface layer 1 reaches plastic state, and cool a little slurry or not cool slurry just can build insulation layer 2.
The built-in fitting arranged in described layer of concrete 3 comprises at least one in the lifting part 33 of prefabricated units integral hoisting, reserved pipeline poling 35, floor drain 34, and built-in fitting is cemented in fill concrete 31.
Pipeline poling 35, floor drain 34 need according to actual design and arrange, and can arrange and also can not arrange, particular location can in any position of prefabricated units, and magnitude setting also according to actual needs.Pipeline poling 35 may be used for installing of the cables such as electric wire, netting twine, data wire.Floor drain 34 is for connecting lower water discharge spout road.
The position that lifting part 33 is arranged is according to the requirement of installation, and general described lifting part 33 is arranged on the end face of layer of concrete 3, and the bottom of lifting part 33 is pre-buried to be cemented in layer of concrete 3, and the top of described lifting part 33 extends to outside layer of concrete 3 end face.Except above-mentioned position, lifting part 33 can also be arranged on hoisting prefabricated component position the most easily, the front of such as prefabricated units or the back side.Pipeline poling 35 is arranged according to actual needs, and pipeline poling 35 may be used for various uses, such as: wire through pipe, running water pipe poling etc., floor drain 34 is for being connected with outdoor house steward by indoor sewage pipe.
If the present invention uses as exterior wall, needing to arrange in the exterior wall of window 8, then described prefabricated units are provided with window 8, and the window frame interlocking of described window 8 is in described layer of concrete 3, and described decorative wall face brick 5, cracking resistance surface layer 1, the corresponding window frame of insulation layer 2 have window.
Described layer of concrete 3 top end face and bottom end face are respectively arranged with for constructing and the tongue and groove of contiguous prefabricated component tongue and groove snapping.Between levels layer of concrete 3, tongue and groove 9 is engaged mutually, corresponding location.The shape of tongue and groove 9 is male-female engagement, and namely the tongue and groove 9 of last layer and lower one deck is male-female engagement mutually.
Because insulation layer 2 is in plastic state, then when arranging cage of reinforcement 32, can be embedded in insulation layer 2 by the end of the cage of reinforcement 32 near insulation layer 2, described skeleton 32 extends in insulation layer 2, can strengthen the adhesion between insulation layer 2 and layer of concrete 3.
In prefabricated units manufacture process, building for every layer is all reaching under plastic state or just build lower one deck after one deck before building at once, then two top layers of adjacent layer are just bonded together into as a whole, do not form sharp interface.Namely between described bonding mortar layer 6, cracking resistance surface layer 1, insulation layer 2, layer of concrete 3, junction is fused into not stratified entirety mutually.Particularly insulation layer 2 is built, and owing to having light heat insulation material in thermal insulation mortar compound, overall light weight, can wait until that cracking resistance surface layer 1 reaches plastic state, and cool a little slurry or not cool slurry just can build insulation layer 2.
Each layer that the present invention adopts different special formulation to make, both had difference in functionality, met the every technical requirements of exterior wall, again can by multiple characteristic unification in overall prefabricated units.The pulp furnish of each layer of the present invention is below described in detail in detail:
