Description

[Detailed description of the invention] This invention separately forms a locking piece for attaching mortar wall material to the panel surface of a rigid and elastic hard board that is shaped to be easily connected, and integrates this with the board. Concerning mortar base plate adhered to.

In general, the base structure for a mortar wall is: ■Lath board - waterproof paper - lath material, ■Cement mortar undercoat layer provided on plywood, for example, Patent No. 941718, ■Insulating material and lath material integrally formed. Japanese Unexamined Patent Publication No. 54-68019 is known.

However, method (2) requires a lot of work and skill, and has the disadvantage of causing cracks and peeling.

Although workability was greatly improved in (2), it lacked heat insulation and weight reduction, and had the disadvantage of causing cracks or peeling at the joints of the base plate.

In case (2), the insulation properties were greatly improved, but the mechanical strength of the integrated part of the insulation material and the lath material was low, and there was a disadvantage that the entire mortar wall could peel off.

In order to eliminate such drawbacks, the present invention has a plurality of long locking pieces arranged at arbitrary intervals, angles, and directions on the panel surface of a panel-like member with a male-female connection structure, so that the mortar wall material and the base plate can be fixed. We propose a mortar base plate that improves the peeling and cracking of mortar wall materials.

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.

In the figure, a main body 1 is formed by bending a hard substrate to have a concave cross section, and has male and female connecting portions 2 and 3 of a fitting structure on the left and right side wall edges.

That is, the male type connecting part 1 consists of an insertion edge 4, and the female type connecting part 3 consists of an engaging groove 5, its lower edge 6, and an extension part 7 extending outward.

Note 2a. 3a is a tongue piece, and 3b is a protrusion provided for cutting ice and strengthening retention as necessary.

8 is a heat insulating material, for example, one or more of gypsum board, rock wool, asbestos, seal insulation board, polyurethane foam, polyisocyanurate foam, phenol foam, polystyrene foam, etc., using a molded product or integrally formed by in-situ foaming. to form.

A waterproof sheet 9 covers the back side of the heat insulating material 8 and is fixed to the lower edge of the male and female connecting portions.

This is largely related to the improvement in mechanical strength due to the sandwich structure of the base plate.

To give a specific example, the waterproof sheet 9 may be a relatively strong sheet-like material such as asphalt felt, kraft paper,
These are synthetic resin sheets, asbestos paper, metal foils, laminates of one or more of these, or sheet-like materials that have been subjected to waterproof treatment.

A plurality of locking pieces 10 are installed on the panel surface 1a of the main body 1 at appropriate intervals and directions and are integrated.

There are various kinds of locking pieces 10, as shown in FIGS. 2a to 2g, and variations thereof are also possible.

The main function of this locking piece 10 is to prevent cracks and peeling of the mortar wall material, and also to reduce the transmission of external forces and vibrations to the mortar wall due to rigidity and elasticity, which ultimately results in cracking and peeling of the mortar wall. The aim is to reduce the

To further explain each locking piece, the tip of the locking piece is shaped like a mountain in figure a, V-shaped in figure b, sawtooth wave in figure 0, net shaped as shown in figure d, and figure e is shaped like a sawtooth wave in figure 0. is semicircular,
The figure f shows a trapezoidal locking piece, and the figure g shows a wavy locking piece with a through hole 11 formed therein.

Further, the length L of this locking piece 10 satisfies W≧L, where W is the width of the panel surface, and the height H is about 5 to 20 mm.

As the material of the locking piece 10, a plate material having rigidity and elasticity is used like the main body 1, and this is integrated with the main body 1 by welding and adhesive.

Further, the locking pieces 10 are arranged as shown in FIGS. 3a to 3d.

That is, a, t) figures are parallel, 0 figures are tilted,
Figure d shows the base plates of the locking piece 10 itself arranged in a meandering shape and facing each other at appropriate intervals.

What has been described above is only one embodiment of the mortar base plate according to the present invention, and the cross-sectional view of the locking piece 10 can be formed not only in an L-shape but also in any shape that can be fixed.

As mentioned above, the base board according to the present invention has the characteristics that the locking piece and the mortar wall material are more integrated, and the construction of the base is easy and highly efficient without requiring any skill. There is.

Furthermore, since the base plate and the mortar wall material are sufficiently integrated, the mortar wall material is less prone to peeling off and cracking.

Furthermore, since it has thermal insulation properties, it has the advantage that dew condensation hardly forms on the back surface of the base plate.

Furthermore, since the locking piece and the main body have elasticity, the transmission of external force and vibration can be significantly suppressed.
