Description

[Detailed Description of the Invention] The present invention relates to a mortar base plate useful as a base for cement mortar walls.

Cement mortar walls used as external walls of buildings are usually made by sealing pieces of wood around the edges, fixing asphalt felt or lath on top of it, and then spraying or brushing cement mortar on it. It formed a mortar wall.

However, when forming this outer wall, not only many steps are required to prepare the base, but also the following points are required.
There was a big drawback.

That is, since the conventional cement mortar wall is formed integrally with the structure of the building, vibrations and the like are directly transmitted to the mortar wall, which tends to cause cracks in the mortar wall.

Furthermore, it is complicated to install the lath material, and since the lath material has a small height difference, the mechanical connection with the cement mortar material is not very strong.

Furthermore, the wood 9 undergoes dimensional deformation due to dew condensation or rain seepage.

That is, the cement mortar wall repeatedly expands and contracts as the evaporation occurs, and this occurs locally, resulting in the formation of cracks and the like.

In addition, as moisture evaporates during reaction hardening of the mortar cement material, the fine ventilation holes shrink as the evaporation progresses.

Since the reaction base does not shrink, cracks and peeling occur due to the degree of contact with the base, differences in the adhesion forces of other adhesion structures, and so-called unbalance of displacement.

In order to eliminate these drawbacks, the present invention integrates a synthetic resin foam that allows water vapor to pass through but has a low water absorption rate on the waterproof layer, thereby significantly attenuating vibrations from the building structure and reducing condensation on the waterproof layer. To provide a mortar base plate which prevents and equalizes moisture in a mortar cement wall after reaction hardening of a mortar cement material, and further integrates a cement mortar material and a reinforcing material.

An embodiment of the mortar base plate according to the present invention will be described in detail below with reference to the drawings.

FIGS. 1a and 1b are perspective views showing a part of the base plate, in which 1 is a synthetic resin foam, and its surface, the surface 2 in contact with the so-called cement mortar material, has holes or holes of appropriate size and depth. A plurality of grooves 3 are provided.

Reference numeral 4 denotes a block made of a hydraulic composition, which is injected into the holes 3 in a fluid state and hardened to integrate with the structure of the metal resin foam.

That is, the anchoring effect is strengthened by penetrating into the structure of the synthetic resin foam, the so-called foam structure in which at least some of the small voids are continuous.

5 is a waterproof layer provided on the opposite side of the synthetic resin foam from the side to which the cement mortar material is attached, that is, the so-called back side.

The waterproof layer 5 functions as a reinforcing material and a waterproof layer for the cement mortar base plate.

To explain in more detail, the synthetic resin foams mentioned above include hard and anti-hard materials such as polyurethane foam, polyisocyanurate foam, and polyurea foam, as well as polystyrene foam, epoxy foam, phenol foam, vinyl chloride foam, and vinyl chloride resin. The foam is made of a foam made by foaming calcium carbonate, calcium carbonate, and asbestos under high pressure. In particular, the foam structure is preferably a foam in which at least some of the cells are continuous with each other.

Further, the cross-sectional shape of the holes, grooves, etc. 3 is not particularly limited, and may be arbitrary, such as circular, oval, triangular, quadrilateral, polygonal, dovetail, etc.

Further, the first composition of the lump of the hydraulic composition is mainly composed of one or more types of Portland cement, gypsum, etc. mixed in an appropriate amount of water, and the second composition is the first composition. A third composition is a composition in which perlite, silica sand, bentonite, talc, vermiculite, shirasu, and pebbles are mixed.The third composition is a composition in which a water-soluble thermosetting resin emulsion is added in place of water in the first composition. It is a thing.

The mass 4 made of this type of composition is filled into the holes 3 described above to an appropriate depth.

For example, filling or protruding as shown in FIGS. 2a-e.

In other words, figure a shows the lump filled to half of hole 3, figure b shows the lump sticking out using a mold material not shown, and figure 0 shows the lump filled flush with the cement mortar adhesion surface. Figure d shows a lump formed with only a portion protruding from the resin foam, and Figure e shows a lump that completely fills the through hole.

Each of these hydraulic compositions is injected into the holes 3 in a fluid state and cured by dehydration or by reaction.

Next, an example of the use of the cement mortar base plate according to the present invention will be briefly described. The cement mortar base plate according to the present invention, for example shown in FIG.

After this, the cement mortar material M is laminated on the cement mortar base plate by brushing or spraying.

In addition to what has been described above, as shown in FIG. 2C, at least a portion of aggregate K such as talc, anti-flinder stone, pearlite vermiculite, etc. may be adhered to the mortar adhesion surface.

As mentioned above, according to the cement mortar base plate of the present invention, ■ Since the synthetic resin foam has elasticity, cracks in the mortar wall caused by vibrations of the building frame (columns) can be greatly reduced. can be prevented.

@Synthetic resin foam has excellent insulation and waterproof properties, so no condensation occurs.

○The synthetic resin foam, which has slightly inferior compressibility, is integrated with a hard mass embedded in the foam structure, resulting in enhanced expulsion compressibility.

■It has good adhesion with cement mortar material, and since the lump with a rough surface is placed on the mortar adhesion surface, there is no chance of the cement mortar material falling off or peeling off.

■Since a complete waterproof layer is integrally bonded to the resin foam, mechanical strength and further waterproofing effects can be obtained.
