Description

[Detailed Description of the Invention] The present invention relates to a mortar base plate that improves the workability of mortar walls, strengthens the adhesion of mortar wall materials, and reduces cracks in mortar walls.

Mortar walls made of flat wood are generally made by sealing strips at intervals between pillars and studs, placing a waterproof sheet on top of this, and then fixing lath material to this using staples. This formed a mortar base, which was then coated with mortar wall material multiple times to create a mortar wall.

However, this type of structure has the disadvantage that the mortar wall material is not directly adhered to the lath board, resulting in weak adhesive strength and frequent peeling and cracking.

Further, this type of base structure has the disadvantage that it requires a very large number of man-hours and requires skill.

Furthermore, as an improved version of this type of base,
No. 20563 exists.

This base plate has considerably improved workability compared to the previous one.
This is intended to reduce cracking and peeling.

However, large cracks continued to occur at the joints between the base plates, and there was still room for improvement in the base as a whole.

Furthermore, since the base board is made of plywood, it has the disadvantage that it absorbs moisture when the mortar wall material adheres to it, and it also bends as the mortar wall material dries (cures), eventually causing cracks and flaking of the mortar wall material. There was a disadvantage.

In order to eliminate these drawbacks, the present invention provides a mortar base plate that has rigidity and elasticity and has a locking piece that physically functions as a reinforcing material, an adhesive material, and an isolating material.

An embodiment of the mortar base plate (hereinafter simply referred to as 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 above-mentioned base plate, and 1 is a board made of plywood, and its size is 900 x 1800 mm.
The plate thickness is 3 to 20 mm.

Reference numeral 2 denotes a locking piece which has rigidity and elasticity and is formed of, for example, a thin metal plate or a synthetic resin plate into an L-shape or the like.

That is, the length 1 is equal to or larger than the width W of the substrate 1, and the height H is 3 to 5 mm shorter than the wall thickness of the attached mortar.

Further, the tip 2a may be formed into a straight line, or may be formed into a wavy (round, square), sawtooth, or other arbitrary shape (not shown).

Furthermore, the plan view of the locking piece 2 is not limited to a straight line, but can be circular, oval, or other bent shapes.

The distribution of the locking pieces 2 is, for example, as shown in FIGS. 2a to 2c.

That is, figure a is in the direction of inclination, figure b is in the direction of surface inclination, and figure c
, d are arranged in parallel, and e is arranged in a grid pattern on the base, and the spacing S is arbitrarily selected depending on the purpose.

Reference numeral 3 denotes a fixing tool, for example a nail as shown in FIG. 3, which fixes and integrates the locking piece 2 onto the substrate 1.

Reference numeral 4 denotes an adhesive layer or an adhesive layer containing aggregate, which covers the substrate 1 and the locking piece 2 as shown in FIG. 1 or FIG. 3 a, l).

In particular, the aggregate forms irregularities on the mortar adhesion surface 1a in order to integrate it with the mortar wall material and strengthen its adhesion.

Furthermore, the adhesive layer greatly contributes to increasing the moisture content of the plywood, so-called waterproofing property, and the adhesive strength.

What has been described above is only one embodiment of the base plate according to the present invention, and the locking piece 2 can also be made to protrude from the edge of the base plate 1 as shown in FIGS. 4a and 4l).

Of course, they may also be made to protrude in a staggered manner. Note that a is
The length of the locking piece 2 is smaller than that shown in photo 4.

As mentioned above, the plywood and the locking piece are integrally formed, and on top of that is an adhesive layer that has good "wetness" with the mortar wall material, strengthens adhesion, and is waterproof, making the mortar There are no cracks or peeling of the walls, and the construction is easy.

In addition, since the locking pieces prevent the plywood from bending due to moisture, the base structure is rigid and has elasticity, which reduces external forces and vibrations.

Claims (1)

[Scope of utility model registration request] A plurality of locking pieces having rigidity and elasticity and having a rectangular cross section are fixed to the plywood at appropriate intervals, and a synthetic resin adhesive or aggregate is applied to the adhesive on the surface containing the locking pieces. A mortar base plate characterized by having an adhesive layer mixed therein and coated and hardened so as not to reduce the unevenness of the aggregate.
