A kind of masonry of precast facade
The utility model relates to building material field, particularly a kind of masonry of precast facade.
Traditional external wall all is first masonry panel, and heat insulating material is installed again, carries out outer the decoration then and handles.Being the technology of disclosed potter's clay plate faced wall in the Chinese patent, 201377135 Chinese patent of 101012673 Chinese patent, 202227544U as publication number, all is to adopt this mode of construction successively.In the mode of this construction successively, body of wall, heat insulating material and ornament materials all are separate products, and the user need divide buying several times, installs respectively at the construction field (site) then, and management cost and construction cost improve greatly, and long construction period, and efficient is low.
The utility model content
The purpose that the utility model will reach provides a kind of masonry of precast facade, at the construction field (site) disposable body of wall, heat insulating material and the ornament materials installed simultaneously.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of masonry of precast facade comprises outside plate and substrate, the described outside plate back side is provided with some draw-in grooves, be provided with the fastener that is complementary in the draw-in groove, fastener is provided with connector, and connector connects fastener and described substrate; Described outside plate and substrate are fitted.
Further, described substrate comprises insulation layer and the body of wall of mutual applying, and described connector penetrates insulation layer and embeds in the body of wall.
Further, described draw-in groove is dovetail groove or T-slot, and these two kinds of flute profiles can prevent that fastener from deviating from draw-in groove.
Further, described fastener embeds in the substrate, strengthens the bonding strength between the masonry each several part.
Further, described connector is anchoring piece, and compared to other connectors such as screws, the bonding strength that anchoring piece provides is stronger and reliable.
Further, described insulation layer thickness 〉=30mm is to reach the heat insulation effect that needs.
Further, the material of described insulation layer is hard foam polyurethane, the light high insulating effect of this heat insulating material quality, the masonry convenient transportation that the utility model is provided.
Further, described thickness of wall body 〉=120mm is to reach intensity and the weight capacity that needs.
Further, be provided with reinforcing bar in the described body of wall, further strengthen the weight capacity of masonry.
Further, the material of described body of wall is haydite concrete or foam concrete, and these two kinds of materials are lighter compared to other materials weight under equal weight capacity, convenient transportation.
After adopting technique scheme, the utlity model has following advantage:
The masonry of the precast facade that the utility model provides can shape in factory, directly is mounted to exterior wall after waiting to be transported to construction site, can reduce construction cost and accelerate speed of application, and this external thermal insulation and outside plate can not come off, and improves construction quality.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of an embodiment of the present invention;
Fig. 2 is the schematic diagram of the required mould of middle processing embodiment illustrated in fig. 1.
The specific embodiment
Accompanying drawing is depicted as a kind of embodiment of the present invention.
See Fig. 1; the outside plate 1 of the masonry of precast facade is the potter's clay plate; have some swallow-tail form draw-in grooves on the outside plate 1; fastener 2 is housed in the draw-in groove; anchoring piece 3 is housed on the fastener 2, and material is that the insulation layer 4 of hard foam polyurethane is fitted with outside plate 1, and material is that the body of wall 5 of haydite concrete is fitted with insulation layer 4; fastener 2 embeds in the insulation layer 4, and anchoring piece 3 penetrates insulation layer 4 and embeds in the body of wall 5.
During the processing masonry, make and assemble the employed mould 6 of masonry of processing precast facade shown in Figure 2 earlier; Then at mould 6 paving potter's clay plates, namely outside plate 1, keeps decorative cover down, namely has the back side of draw-in groove up, and on draw-in groove mounting clip pieces 2, at fastener 2 anchoring piece is installed; Form insulation layer 4 at the back side of outside plate 1 spraying heat insulating material hard foam polyurethane then, the thickness of insulation layer 4 is not less than 30mm, after spraying is finished insulation layer 4 is carried out maintenance, guarantees that the heat insulating material knot of insulation layer 4 is solid, reach hardness and the intensity of design, and rate of closed hole is more than or equal to 95%; Build haydite concrete at insulation layer afterwards and form body of wall 5, the thickness of body of wall 5 is not less than 120mm, and in time body of wall 5 is carried out vibration processing and surface finish is handled, and guarantees more standard of the shape that there is not the problem of cavity segregation in body of wall 5 knots after solid and makes masonry; At last the related mould of masonry is moved to fog room and continue maintenance until reaching designing requirement, masonry is carried out the demoulding, from mould, take out fixing successively outside plate 1, insulation layer 4 and body of wall 5, obtain described masonry.
Hard foam polyurethane is a kind of good heat insulation effect material; and quality is lighter; and the quality of haydite concrete is compared to the concrete of other kinds; tool has great advantage on strength-weight ratio; adopt these two kinds of materials and potter's clay plate to constitute masonry; make that the masonry quality is lighter, it is very convenient to be transported to the job site from factory.Can also add reinforcing bar in the masonry, make the weight capacity of masonry further strengthen.
The material of body of wall 5 also can use high strength foam concrete.
Except above preferred embodiment, the utility model also has other embodiment, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
