Description

[Detailed Description of the Invention] The present invention relates to a mortar base plate provided with a heat insulating material and useful as a mortar base material for internal and external walls of buildings and structures.

Generally, when forming a mortar wall, the underlying structure is ■Lath board - waterproof paper - lath material, ■Patent No. 941718
No. ◎Synthetic resin foam-lath material is well known.

However, in this type of base structure, the mortar wall cracks or falls off in severe cases.

○ Particularly, the bases marked ■ and ◎ had drawbacks such as frequent cracking and falling off of the mortar walls at the joints between the base plates.

The present invention was devised in view of these shortcomings, and is particularly effective by simplifying and increasing the efficiency of construction, suppressing cracks and falling off of the mortar wall at the joints of base plates, and combining it with a lightweight heat insulating material. The present invention provides a mortar base plate that can function as a structural material and provide heat insulation properties all at once.

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

FIG. 1 is a perspective view showing the base plate, where 1 is the main body;
A hard substrate having a certain degree of elasticity and being plastically deformable is formed into a concave cross-section by pressing, rolling, etc., and side walls 3 and 4 are formed into a square or rectangular shape and are inclined in the same direction as the bottom part 2;
It consists of male and female connecting portions 5 and 6 formed on its edges.

Further, the bottom surface portion 2 is provided with a plurality of locking pieces 7 which are partially cut and protrude upward.

More specifically, the locking piece 7 is formed to have a cross-sectional shape as shown in FIGS. 2a and 2e.

That is, the figure a shows the locking piece 7 expanding toward the end in a curved line, and the figure b shows the locking piece 7 protruding perpendicularly to the outer surface 2a, and only the tip 7a is bent to form a substantially hook shape.

Figure C is the same as Figure B, but the tip 7a is connected to the outer surface 2a.
Figure A shows a shape in which the locking piece 7 is tilted in a straight line.

In figure e, the tip 7a of the locking piece 7 shown in figure a is set at an angle θ,
It has a bent shape.

The height H of this locking piece 7 is arbitrarily set depending on the thickness of the mortar wall, but for example, if the wall has a thickness of 2-
It has about 5 ribs, and the diameter is arbitrary.

Furthermore, the shape of the locking piece 7 in plan view is various, as shown in FIGS. 3a to 3j, and may be formed into a crown-like shape consisting of one piece, three pieces, or multiple pieces depending on the purpose.

The locking piece 7 can be formed by using a general press, a press with notches, or a burring process to exceed its limit and cause cracks to occur at the periphery of the burring part.

Of course, in order to make the locking piece into a complicated shape, the locking piece may be bent, punched, etc. before it is projected.

To explain further, in Fig. 3, figure a shows the case where three rectangular locking pieces 7 are formed as shown in a, and figures b-d show the case where triangular locking pieces 7 are formed on the periphery of the circle as shown in b. This is a case where four pieces or a plurality of pieces (not shown) are formed, and Fig. e shows a case where a triangular locking piece 7 is formed around the periphery of a hexagon.

Of course, when burring is performed using a polygonal punch, the locking piece 7 will be formed accordingly.

Fig. 3f shows the case where the locking piece 7 is formed by dividing the periphery of the ellipse into a large number of pieces, and Fig. 3g shows the case where the rectangular locking piece 7 is formed high. This is a case where the periphery of a square is formed into four locking pieces 7, and Figure J is a case where the periphery of a triangle is formed into three pieces.

Furthermore, the distribution of this type of locking piece 7 is arranged as shown in FIG. 4a"d.

That is, diagram a is a random distribution, diagrams b and c are regular distributions, diagram b is a staggered distribution, and diagram C is a distribution of the base.

Of course, the distribution is not limited to this, but it can be distributed in a diamond shape, a polygonal shape, a circular shape, etc., and the locking pieces 7 can be arranged in two (as shown in Fig. 4 d) or three in succession, or with narrow intervals. It is also possible to arrange them.

Note that in forming the mortar base plate, regular distribution is convenient for later manufacturing steps.

The most suitable material for the main body 1 provided with such a locking piece is a metal plate or a synthetic resin plate, such as a surface-treated steel plate (galvanized iron plate, colored iron plate, etc.), a stainless steel plate, a lath plate,
It is preferably a steel plate or the like, and the plate thickness is preferably 3.2 mm or less from the viewpoint of forming.

Further, the male type connecting part 5 is composed of an insertion edge 8 that extends the edge of the side wall 3 outward, and the female type connecting part 6 is formed by bending the edge of the side wall 4 inwardly and then bending it outward again. The engagement hole 9 is formed by extending the lower edge 10 of the engagement hole 9, and is composed of a protrusion 11 protruding in the middle thereof and a lip (tongue) 12 having a bent tip.

In particular, the protrusions 11 serve to press the heat insulating material 13 and strengthen the connection during connection, as shown in a partially enlarged view in FIG.

The heat insulating material 13 is filled into the recessed portion, and is formed, for example, by using a molded body or by foaming in place by discharging raw material (liquid).

As this heat insulating material 13, synthetic resin, especially foam, is used.

Specific examples include polyurethane foam, polyisocyanurate foam, phenol foam, and polystyrene foam.

In the in-situ foaming method, it is very preferable to use raw materials that have self-adhesive properties in order to integrate the constituent materials.

In addition, in the case of the on-site foaming method, the discharge timing is controlled so that too much raw material leaks to the outer surface 2a from the gap where the locking piece 7 is formed, or nonwoven fabric, tape, etc.
A suppressing layer such as aggregate is provided inside the bottom part 2.

14 is a relatively strong waterproof sheet, such as asphalt felt, kraft paper, synthetic resin sheet, asbestos paper, metal foil, a laminate of one or more of these, or a sheet-like material that has been subjected to waterproof treatment. be.

What has been described above is only one embodiment of the mortar base plate according to the present invention, and the heat insulating material 13 contains one or more of pearlite grains, zeolite, borax, styrene beads, and fibers to provide fire resistance, compression resistance, and sound absorption. For 10 parts of raw material due to
It is also possible to add about 10 to 10 parts by volume.

Further, in FIG. 1, the waterproof sheet 14 can also be projected outward as shown by the two-dot chain line.

Also, the slope θ of the side wall is arbitrary other than 90°, 30°, 4
5°, 60° and 75° are preferred.

As mentioned above, according to the mortar base plate according to the present invention, the base formation of the mortar wall is: (1) easy and highly efficient, and does not require any skill, and (2) cracks in the mortar wall at the joints between the base plates. Since the entire surface of the mortar wall resembles the same underlying structure, cracks and the like can be largely suppressed.

■Since the base plate functions well as a structural material, it is possible to reduce the occurrence of cracks caused by external force on the mortar wall from the frame.

■Since it forms a base that is both heat-insulating and waterproof at the same time, it has great economic and manufacturing advantages.
