The area of each foamed cement heat-insulating wall board is preferably 0.2-0.8 square meter. The width of the strip-shaped gap is 10-25 mm.
Description
Technical Field
The utility model relates to a thermal insulation wallboard, especially a blank pressing installation formula foaming cement thermal insulation wallboard especially composite insulation wallboard.
Background
The heat insulation coefficient of the building is an important assessment index and becomes the requirement of the hard index of the existing building, so that the adoption of a heat insulation mortar layer and even a heat insulation wallboard in the existing building is an important way for improving the heat insulation coefficient (energy-saving coefficient) of the existing building, the heat insulation mortar layer is formed by permeating a large amount of EPS into cement mortar, the material cost is not high, the construction cost is higher, the design margin is not large particularly during the preparation of a facing plastering, the facing of an outer wall needs to be installed on site, the construction quality of the heat insulation mortar layer is not easy to control in general, the adhesive force of a large amount of cement mudflats is generally lower, and the spalling phenomenon is difficult to avoid. Thermal insulation mortar
The prior art has considered the advantages of the foam cement thermal insulation wallboard in application, but the foam cement thermal insulation wallboard is not enough in installation, the adhesive force of cement paste is generally low, the thermal insulation wallboard can easily fall off, and the installation of the foam cement thermal insulation wallboard in a large area is preferably the installation of the cement paste and expansion screws, which is the best mode for adding the existing building.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a blank pressing installation formula foaming cement thermal-insulation wallboard to the board that can not reach 2.5 centimetres thickness can satisfy building energy saving coefficient requirement (the coefficient of heat dissipation of certain difference in temperature, has important energy-conserving meaning to air conditioner and winter keep warm summer), especially dual structure's mounting means, and the installation is firm and easy.
The utility model discloses technical scheme: the utility model provides a blank pressing installation formula foaming cement heat preservation wallboard, the shape is the foaming cement board of rectangle, the utility model discloses a design is a long banding step of length of preparation or width direction's both edges department at the foaming cement board of rectangle, and the foaming cement board is the structure of two-layer board promptly, and the length of upper plate or width are less than down the plywood, then the edge of plywood exposes a rectangular form space down. The area of each foamed cement heat-insulating wall board is preferably 0.2-0.8 square meter.
The structure can be a strip-shaped notch formed by cutting the upper layer, and also can be a foamed cement composite heat-insulation wallboard formed by two layers of boards.
The first foamed cement board (base plate) and the second foamed cement board (panel) are used as composite boards, the density of the base plate is high, the strength can be high when the cement paste is used for lining, and the polypropylene or polyethylene fiber net lining is added, so that the overall strength is high, and the good yield can be ensured during transportation and facing.
Has the advantages that: the utility model provides a blank pressing installation formula foaming cement heat preservation wallboard, foaming cement heat preservation wallboard can not have the contradiction in coefficient of heat conductivity and in-service use, can also with the wainscot integration, can not satisfy the building energy saving coefficient requirement by the board of 2.5 centimetres thick (the coefficient of heat dissipation of certain difference in temperature, it is significant to air conditioner and cold-proof winter in summer). The utility model discloses a succinct structure, compound incubation wallboard have two insulating layers, and basement density is big, and material cost is low, and is rational in infrastructure, and intensity is big, save material, and outer thermal-insulated effectual, light in weight adopts inorganic material basically, long service life, and intensity meets the requirements, and the construction is easy. The utility model discloses difficult damaged does benefit to large-scale application.

Detailed Description
As shown in fig. 1, the utility model relates to a blank pressing installation formula foaming cement heat preservation wallboard, two-layer board constitute the further structure of foaming cement composite insulation wallboard: the first foamed cement board 1 and the second foamed cement board 2 are bonded with cement slurry through a polypropylene or polyethylene net 4, the thickness of the first foamed cement board and the thickness of the second foamed cement board are both 10-17 mm, the thickness of the first foamed cement board and the polypropylene or polyacetylene net after the first foamed cement board and the second foamed cement board are compounded is 22-36 mm, the density of the first foamed cement board is 0.9-1.2, and the density of the second foamed cement board is 0.4-0.6; the first foamed cement board is used as a substrate and can be directly pasted on a wall surface by cement paste, and the second foamed cement board is arranged on the outer layer. Primarily fixing the foamed cement heat-insulating wall board with cement paste; the upper edge, the lower edge, the left edge and the right edge (the lines of all steps are in the same direction) of the foam cement heat-insulation wallboard are exposed out of a strip-shaped gap 3, the strip-shaped gap 3 can be pressed by a pressing strip, the width of the pressing strip is twice of the width of the strip-shaped gap 3, two adjacent edge-pressing mounting type foam cement heat-insulation wallboards can be pressed by the pressing strip, the edges of the foam cement heat-insulation wallboards can be pressed by the pressing strip, and the pressing strip is fixed with a wall body. The fixing mode of the pressing strip and the wall body by the expansion screw is a common structure, the nut sleeve is fixed in the wall body through a punched hole, and then the pressing strip is fixed in the nut sleeve through the hole on the pressing strip by the screw. The batten can be made of weather-proof high polymer materials or inorganic magnesite (fibers such as glass fibers are added). The width of the bead is 20-50 mm. The width of the elongated voids is 10-25 mm.
The first foamed cement board is used as a substrate and can be directly pasted on a wall surface by cement paste, and the second foamed cement board is arranged on the outer layer. The density is low, the heat insulation effect is good, and the condition that the heat conductivity is affected by the base plate cement paste is not fully coated.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention. The present invention is intended to cover by those skilled in the art various modifications and adaptations of the invention without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention is subject to the claims.
