Abstract

A hollow painting layer is made of a drainage plate with a plane and a rib and a keel, and relates to building surface painting. The prior method is that the steel wire mesh, the keel and the drainage plate are fixed by expansion bolts, so that cement mortar is combined with the steel wire mesh, and the defect that the cement mortar is blocked by the steel wire mesh during plastering, so that the cement mortar and the plastic drainage plate cannot be completely compacted. Cancel the wire net, do not receive the stopping of wire net when making whitewash, the fulcrum side of plastics drain bar is fluted stiffening rib, also fluted stiffening rib on the plane, and the side of plastics fossil fragments has the shape of C type, installs expansion bolts again and includes big plastics block, fixes, then whole interface liquid that spouts, directly whitewashes cement mortar and plastics drain bar and fossil fragments interlock each other. The hollow layer has a series of advantages of heat preservation, sound insulation, moisture prevention, drainage and the like, and the simpler process, the wider the application range, and the construction method which can be popularized and applied is provided for the building wall surface.

Description

Hollow painting layer made of drainage plate with plane rib and keel

One, the technical field

The invention relates to a product and a construction method, relates to building surface painting, and can form a hollow layer between a structural wall and painting on the indoor surface or the outdoor surface of the structural wall, wherein the hollow layer has a plurality of physical functions.

Second, background Art

The inventor has been engaged in the innovative process of hollow layer, the former method is to fix the steel wire mesh, the keel and the drainage plate by using expansion bolts to combine the cement mortar with the steel wire mesh, so the steel wire mesh and the keel are fixed together by using the expansion bolts, and the drainage plate is fixed by using the keel. The main joint relationship is as follows: the painting is combined with the steel wire net, and the steel wire net is fixed before painting. The defects are that cement mortar is blocked by the steel wire mesh during plastering, so that the cement mortar and the plastic drainage plate cannot be completely plastered, and a plurality of gaps are formed. In addition, when the expansion bolts are installed, if the holes are bored at the fulcrum positions, the wet phenomenon is easily guided to the painted surface, so that the expansion bolts are installed on the plane between the fulcrum and the fulcrum at the position of the hollow layer, so that the seepage water flows down from the hollow layer without being guided to the painted surface, thereby making the following invention.

Third, the invention

Firstly, the combination relation of painting is changed, the steel wire mesh is cancelled, so that the painting is not blocked by the steel wire mesh, the space between the keels is encrypted, and the basic drainage plate has no elastic room. The side face of the fulcrum of the plastic drainage plate is provided with a groove stiffening rib, the plane is also provided with a groove stiffening rib, and interface liquid is sprayed on the surface of the plastic drainage plate, so that cement mortar can be directly pulverized on the surface of the plastic drainage plate. The side of plastics fossil fragments has the shape of C type, presses on the drainage face, bores on fossil fragments, drain bar and structure wall with the impact and punches, installs expansion bolts again and includes big plastics block, fixes, then wholly spouts interfacial fluid, directly whitewashes cement mortar and plastics drain bar and fossil fragments interlock each other. The recess stiffening rib on the plastics drain bar plane breaks off on the plane between two fulcrums in 150 ~ 400mm interval, and the width of a fossil fragments is opened to the sky, makes plastics fossil fragments can the location install in this position, both reduces the protrusion height, makes expansion bolts's position can not get into the position of fulcrum again, avoids producing the diversion. The plastic drainage plate is vertically laid, a supporting point is arranged on the left hasp and the right hasp, the height of the supporting point is 1-2 mm lower than that of other supporting points, the plane groove stiffening ribs are pressed into each other, and then the plastic strip is arranged to seal the plane groove stiffening ribs to form a sealed whole.

Through the improvement, the cement mortar is densely filled with the drainage plate and the keel, the construction process is simplified, the cost is reduced, the quality is improved, the hollow layer has a series of advantages of heat preservation, sound insulation, moisture prevention, drainage and the like, the simpler the process, the wider the application range is, and the construction method capable of being popularized and applied is provided for the building wall surface.

Fifthly, specific implementation method

The surface of the integral plane 1 of the drainage board in figure 1 is provided with a fulcrum 2 and a plane groove stiffening rib 3, and the plane groove stiffening rib 3 is arranged in a distance of 150-400, and a hollow 4 is reserved between the two fulcrums so as to be used for installing a keel later.

FIG. 2 is a cross-sectional view taken along line 1-1 of FIG. 1, with the side of the anchor 2 having recessed stiffeners and the flat side having recessed stiffeners 3 for engaging the cement mortar.

Fig. 3 is a sectional view of a plastic keel, a keel 8 is provided with two stiffening ribs 5 which can ensure the rigidity of the keel, the top end is provided with an unfolded side wing 7, and the side surface is provided with a raised flanging 6 to form a C-shaped shape for wrapping cement mortar.

Figure 4 is a plan view of the installation and figure 5 is a 2-2 sectional view of the keel 8 installed in the place of the hollow 4 of the channel stiffener 3 in the plane of the drain board, after drilling the keel, drain board and structural wall with the hammer drill, the expansion bolts 9 are installed to ensure that the expansion bolts are all positioned in the plane between the fulcrums and will not guide the water seepage to the painted surface, which will flow down in the hollow. And finally, spraying interface liquid 10, which is water-containing latex, on the installed drainage plate surface, wherein the interface liquid can be firmly bonded with plastics and can be fused with cement mortar.

FIG. 5 shows the snap-fastener connection of the left and right fulcrums 12 of the drainage board, wherein the fulcrums 12 are 1-2 mm lower than other fulcrums, and the planar groove stiffeners 3 are compacted and simultaneously squeezed into the adhesive tape 11 to form a closed surface layer.
