Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a base substrate for fixing exterior blocks such as bricks and tiles used for the exterior of buildings.

[Prior Art] In the first dry method for fixing this type of exterior block, grooves for engagement are provided on the back surface of the exterior block, and a base substrate for fixing the exterior block is provided with a holding means that fits the grooves. It is supposed to be used.

This fixed base board is made of a steel plate, for example, as in Utility Model Application No. 63-165029, and hook-shaped holding protrusions that match the grooves of the exterior block are partially cut and protruded by press working, or As in Japanese Utility Model Application No. 57-195452, a separate rail-shaped retaining strip was fixedly protruded on a base plate.

On the other hand, it is also known that the fixing base substrate is made of extruded cement that has been subjected to an autoclave treatment, and a holding portion is attached thereto.

[Problems to be Solved by the Invention] However, among this kind of conventional exterior block fixing base substrates, those made of steel plates are thick because they are heavy, and the processing is complicated, and they are required separately. Those with fixed protruding retaining strips require accurate positioning when fixing them, which poses a problem in workability on site, and cement-made ones have problems with fixing the base substrate itself. Nails and screws may break when used, and especially in cold regions or during cold periods, rainwater or condensation water enters these nail holes, which freezes and expands, resulting in cracks appearing in the fixing base board after the exterior is completed. is left behind.

The present invention has been made in view of these problems, and its purpose is to provide a lightweight exterior block that can be easily and reliably held and fixed, and that does not cause problems during long-term use. To provide the underlying substrate.

[Means for Solving the Problems] The present invention comprises a single thin metal surface plate and a thick closed-cell foamed resin layer that is integrally bonded to the back surface of the surface plate, and the surface plate is formed by roll forming. An exterior block fixing base substrate (Claim 1) characterized in that it is formed into an uneven plate shape in which a plurality of continuous horizontal holding grooves and surface protrusions are carved alternately (Claim 1); An exterior block fixing base characterized in that an adhesive holding part or a joint holding part is additionally provided in the surface protrusion or holding groove of item 1 by means of narrow grooves or minute irregularities similarly carved by roll forming. The present invention relates to the substrate (Claim 2), and each of these is the gist.

[Function] According to claim 1 of the present invention, after fixing the fixed base substrate to the pillars or walls of the building with nails or screws penetrating the surface plate,
Each exterior block is engaged and placed on the retaining groove, and the back side is faced to the surface protrusion, and fixed with adhesive, etc., and a joint material is interposed between the exterior blocks at the position of the retaining groove or surface protrusion. In addition, in the second aspect of the present invention, the adhesive or joint material is further held by the holding portion to improve the adhesive strength of the exterior block or to prevent the joint material from falling off.

Note that the thick foamed resin layer holds the nails or screws of the fixed base board in an elastic manner, preventing rainwater and dew water from being introduced into the fixed base board, and even if these penetrate and freeze, the nails or screws will be held firmly in place. In addition to absorbing the expansion of the body 81, the thick foamed resin layer has excellent heat insulation and sound insulation properties.

[Examples] The present invention will be further explained below with reference to the drawings showing examples. In FIGS. 1 and 2, 1 is a fixed base substrate;
This fixed base substrate I has a thickness of, for example, 17 mm to 20 m.
It is configured as a horizontally long one with a height of 630 mm and a width of 5.00 mm, and a single surface plate 3 made of colored steel plate.
and a thick foamed resin layer 15 integrally bonded to the back surface thereof.

In this example, the fixed base substrate 1 is formed by forming the thick foamed resin M15 by foaming and filling closed-cell hard urethane foam into the box 2 including the surface plate 3.

In other words, one box 2 has a thin surface plate 3 of 0.27 mm to 0.3 g+m, side wall plates to and ii with the upper and lower ends of this surface plate 3 bent toward the back side, and side wall plates 10 and 11 between the ends. The foamed resin is supplied to one of the continuously long front plate 3 and the back plate 14, and then the other is supplied oppositely to form a pressurizer. The fixed base substrate 1 is obtained by performing foaming and cutting the box body 2 and the foamed adhesive-integrated product according to the predetermined width.

The surface plate 3 undergoes a roll-forming process prior to the formation of the foamed resin layer 15, and by this roll-forming, the surface plate 3 (in this example, a large number of continuous horizontal retention grooves in the upper and lower width directions made of 9 wood) is formed. 4... and surface protrusions 7... are alternately engraved, so that the overall surface is shaped like an uneven plate.

Each retaining groove 4 has a retaining base wall 5 at its lower part that is slightly inclined toward the lower back surface, while the upper part thereof is provided with a loose fitting part 6 which is more acutely inclined toward the upper rear surface and has a dovetail cross-sectional shape. It is constructed to have a groove shape, and the surface protrusion 7 is located between these holding grooves 4, 4 so as to form a vertical surface.

In addition, 8 in the figure is a nail or screw 9 to the pillar etc. of the fixed base board l.
12 and 13 are a pair of fitting protrusions and fitting grooves provided for connecting the upper and lower parts of the fixed base substrate l. 16 are nails or screws for fixing the fixed base substrate l within the upper end holding groove 4.

On the other hand, 17 is an exterior block fixed by this fixed base substrate l, and specifically, for example, bricks or tiles of an appropriate color sintered at high temperature are used.

The exterior block 17 of this example has a height of 60 ts and a width of 108 to 227 cm, and has a height dimension slightly smaller than that along the cross-sectional shape of the retaining groove 4 on the back side of the block body. In addition, a dovetail-shaped engagement protrusion 18 whose upper part is cut into the block body side is integrally provided.

This exterior block 17... has its engagement protrusion 18 gradually inserted into the holding groove 4 of the fixed base substrate l from the front side, while the back surface of the exterior block 17 is attached to each surface coated with adhesive. Each exterior block 1 faces the protrusion 7 and
Joint mortar 19 is filled and fixed as a joint material at the end of each surface protrusion 7 between 7....

3 and 4 show another fixed base substrate 20.23. In FIG. These are joint holding parts made of narrow dovetail grooves that were similarly carved by roll forming at the same time as the formation, and 25 and 26 in FIG. It is an adhesive holding part or a joint holding part by a large number of narrow grooves,
These holding parts 25 and 26 allow the joint mortar 19 to
This is to prevent the exterior block 17 from falling off due to biting, and to improve the adhesive strength of the exterior block 17 due to the accumulation of adhesive. The rest is the same as the previous example, so the same reference numerals are given and the explanation thereof will be omitted.

FIG. 5 shows yet another example of the fixed base substrate 27,
In this example, the height and width of the holding grooves 4 of the surface plate 28 are made large and the surface protrusions 7 are made small, while the slope of the holding base wall 5 is made steep to change the cross-sectional shape of the holding grooves 4. It is supposed to be closer to the dovetail groove.

Contrary to the above, the exterior block 29 in this case integrally has a pair of engaging protrusions 30, 30 facing each other at the upper and lower ends so as to receive the surface protrusions 7 on the back side of the central part, respectively. Exterior block 2 in which retaining grooves 4 are arranged above and below
The lower and upper engaging protrusions 30, 30 of 9 are received with the joint mortar 19 interposed therebetween, and the fixed base substrate 27 is fixed with nails or screws 31 at positions corresponding to the joint mortar 19. .

Since the rest remains the same, the same reference numerals are given and the explanation will be omitted.

The illustrated example is as above, but in the present invention, the surface plate may be used in addition to the color steel plate mentioned above, for example, from 0.27 mm to 0.27 mm.
It is practical to use various types of rust-proof steel plates such as PVC steel plates and stainless steel plates with a thickness of about 30 mm, or metal plates such as aluminum alloy plates with a similar thickness of about 0.4 mm.

In addition, it is also possible to form a closed-cell thick foamed resin layer of isocyanurate foam, phenol foam, or the like.

It is also possible to bond and integrate a pre-formed thick foamed resin layer to the surface plate using an adhesive, but in order to ensure sufficient integrity with the surface plate, which is shaped like an uneven plate, the above method is not recommended. As shown in the example, it is desirable to utilize the adhesive properties during foaming.

At this time, a foaming agent can be sprayed on the back side of the top plate to cause foaming, but it is also possible to provide the back side with a paper material or a metal foil vapor-deposited material in addition to the above-mentioned metal back plate and fill it by internal foaming. It is effective in improving

By the way, in the example illustrated above, the joint holding parts and adhesive holding parts 1, for example, in FIG. In addition, as shown in FIG. 5, these can be provided at positions corresponding to the joint material of the surface protrusion or the retaining groove.

In addition, the dimensions of the fixed holding substrate and the exterior block, the number of shapes of the protrusions on one surface of the holding groove, etc. can be determined as appropriate, and as is clear from 1 or more, each specific configuration in carrying out the present invention can be determined as appropriate. The materials, shapes, dimensions, etc. can be changed in various ways as long as they do not go against the gist of the invention, and there is no need to limit them to what has been shown and described above.

[Effects of the Invention J Since the present invention is constructed as described above, it has the following effects.

In other words, the fixed base substrate is made up of a single thin metal surface plate and a thick closed-cell foamed resin layer that is integrally bonded to the back surface of the thin metal surface plate, which reduces its weight and makes it lighter than conventional ones. Even if it is large in size, it is easy to transport and fix, improves workability, and can be highly heat-insulating and sound-proof. In addition, even if it is fixed with nails or screws, the thick foam resin layer itself has elasticity, so it is effective in holding it elastically and preventing the intrusion of rainwater and condensation water. There is no possibility of breakage even if it freezes, and it is suitable for cold regions and has sufficient durability.

Furthermore, even though the surface plate is thin, the thick foamed resin layer is integrally bonded, so it maintains sufficient self-supporting strength and can be used to securely support a large number of exterior blocks without worrying about its strength, and it can also be fixed with nails or screws. It can be done freely and the work can be done easily.

In addition, the surface plate is provided with retaining grooves and surface protrusions to stabilize each exterior block, and since these are engraved on the roll I & mold, high dimensional accuracy can be obtained, and the adjacent fixed base substrate There is no difference in level between them, and the reference position for fixing the exterior block can be accurately obtained.

Furthermore, it is easy to obtain long pieces in the width direction, and since there are no hook-shaped holding protrusions on the surface plate, deformation due to external forces such as during transportation can be prevented, and even if deformation occurs, it can be easily avoided. It can be repaired with a hammer, etc.

On the other hand, in claim 2, since the adhesive holding part or the joint holding part is additionally provided, in addition to the above effects, the exterior block is firmly fixed by the adhesive pool, and the joint material is bitten. It is possible to easily and reliably prevent the product from falling off.

As described above, the present invention can provide an ideal exterior block fixing base substrate that has good workability and is excellent in heat insulation, sound insulation, water resistance, and durability even after the exterior is completed.
