Abstract

PURPOSE:To enable construction panel to be fitted from the back side (interior of a building) when conditions do not allow to fit the construction panel from the front side because of such reasons as narrow space between buildings in such places as densely built-up areas. CONSTITUTION:A locking portion 24 of a fitting means B, which is formed almost in the same shape as a male connecting portion, is fitted and interposed between panels formed by means of a male-female connection structure. A fitting surface 23 of the fitting means B is secured to a lathing D of a column shape made of a C-shape steel by means of a securing means such as bolts and nuts or welding means and a panel A is fitted to the lathing D. Thus a panel can be fitted from the back side of the panel, in other words, from inside of a building and furthermore, the fitting work can be accomplished by not deteriorating the normal fitting strength and workability.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building panel mounting structure for forming an outer wall of a building or a structure.

[0002]

2. Description of the Related Art Conventionally, this type of building panel (hereinafter, simply referred to as "panel") is attached to a wall substrate by, for example, FIG.
As shown in FIG. 0, the concave groove of the lower panel a ₁ is fixed to the wall foundation α made of steel frame foundation with a fixture β such as a hex or a tex, the upper panel a ₂ is dropped, and the concave groove is formed on the upper surface thereof.
That is, a mounting structure is being put on the market in which the head of the fixture β is covered and construction is carried out sequentially from the lower stage to the upper stage.

[0003]

However, the above-mentioned mounting structure is only a mounting structure from the panel surface side, and as the density of buildings is increasing as seen in today's large cities, the space between buildings is There is a drawback that the above-described conventional mounting structure cannot be used under the condition that the scaffolding for mounting the panel cannot be installed from the front side in a narrow space.

[0004]

Therefore, in the present invention, a male,
Via the locking portion of the fixture between the panels formed by the female connection structure, the fixing surface of the fixture is further fixed to a columnar wall base such as C-shaped steel by a fixture such as a bolt-nut or by means such as welding. Since it is fixed and the panel is attached to the wall foundation, the panel can be attached from the back side of the panel, that is, the interior side of the building, and the structure can be attached without losing the usual attachment strength and workability. It is a proposal.

The male-type connecting portion 6 has an upper edge 8 that further projects the tip of the subterranean ground 5 to the outside.
And a lower edge 9 in which the tip of the upper edge 8 is bent inward in a substantially inverted U-shape.
The insertion edge 7 is composed of the insertion edge 7, the concave groove 10 formed in the upper edge 8 of the insertion edge 7, and the reinforcing piece 11 in which the tip of the lower edge 9 is bent inward in an L-shape.

As shown in FIG. 2, the inserting edge 7 is a portion which is inserted into a fitting groove 15 of a female connecting portion 12 which will be described later and is fixed to the wall base D, and a fixing groove of a fixture B which is described later. 25
It is a part that is inserted and locked in and is integrated with the fixture B. The recessed groove 10 is a portion that locks the locking piece 26 of the fixture B and forms a void in the connecting portion to prevent a capillary phenomenon and enhance waterproofness.

The female connecting portion 12 has an upper surface 13 in which the lower end edge of the side wall 4 is bent inward, a lower surface 14 in which the tip of the upper surface 13 is bent outward, and a substantially inverted U-shaped cross section from the upper surface 13 and the lower surface 14. It is composed of a fitting groove 15 formed in a shape and a reinforcing piece 16 in which the tip of the lower surface 14 is projected inward. This fitting groove 15
Is a portion that is engaged with the insertion edge 7 of the male connecting portion 6 and fixes the panel A to the wall base D. The steps 2b and 2c formed on the decorative surface 2a are designed to have a step-like makeup joint so that the joint portion is three-dimensionalized and clarified to improve the design.

As shown in FIG. 3 (c), the back surface material 17 has an inner piece 18 in which one end edge of a long plate material is bent inward in parallel with the plate material and is bent in an L-shape, and the other end edge is outward. Is formed from an outer piece 19 that is substantially parallel to the plate material and is bent in an L shape. In the figure, the tips of the inner piece 18 and the outer piece 19 are bent upward to stabilize the stable piece 18.
a and 19a are formed to function as a guide surface at the time of engagement and a mold at the time of production, and a gutter-shaped portion 17a is formed from these.

The male part 22 is engaged so as to be inserted into the connector 1 to connect the panels A to each other. Further, the inner piece 18 and the outer piece 19 of the back surface material 17 are for greatly improving fire resistance, waterproofness, and airtightness at the connecting portion, and especially in case of a fire, the flame enters the back surface 17b. This is to prevent panel A from becoming panel A that can pass the fire resistance test.

The core material 20 is mainly made of synthetic resin foam and functions as a heat insulating material, a waterproof material, a soundproof material, a cushioning material, a fireproof material, and the like. For example, polyisocyanurate foam,
