Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a building panel (hereinafter simply referred to as a panel) useful for constructing an outer wall and an inner wall of a building and a building. More specifically, even if the decorative surface width and the panel thickness are increased, the male and female fitting structures do not peel off from the wall base, and fixtures such as nails are not exposed to the outside. It relates to a panel that can be stretched horizontally.

[Conventional technology]

Conventionally, as this type of panel, as shown in FIG. 11, a panel a having a real structure formed on the back side is connected by a male-female fitting structure, and an end of the panel a _{1 is} attached to a wall base α. A fixing device using a fixing tool β has been proposed.

[Problems to be solved by the invention]

However, a gap γ is formed between the panels a ₁ and a ₂ by the head of the fixing tool β, and rainwater or the like blown up from the joint portion b is transmitted to the wall foundation α by the large gap γ, and the wall foundation is formed. There was a disadvantage of corroding α. In addition, fixture β
Is formed in the vicinity of the joint b, so that rainwater or the like directly reaches the head of the fixing tool β and the fixing hole formed in the panel a ₁ by the fixing tool β. However, there are drawbacks such as infiltration of rainwater into the wall foundation α from the fixing holes. Furthermore, the fixing tool β was visible from the outside through the gap in the joint portion b, and the aesthetic appearance was significantly poor. Further, the reinforcing piece c formed in the core material is fixed by the fixing tool β. However, when the panel a ₁ is fixed by the fixing tool β, the reinforcing piece c is deformed and the fixing piece β is fixed. It was extremely difficult to cast, which was a major drawback in construction. Furthermore, if the core material is a synthetic resin foam, the front surface material during production, covered with a sheet-like material so as not to leak from the end between the back material,
In order to further enhance waterproofness and airtightness, a packing or the like must be interposed in the female portion, and two members, a sheet-like material and a packing, are indispensable.

[Means for solving the problem]

In order to eliminate such drawbacks, the present invention fixes the panel at one end and also fixes the panel from the front side of the surface material by using the fixing groove of the male connecting portion and the upper surface of the female connecting portion. In addition, the combination of the drop-in structure and the actual structure improves waterproofness and workability, and also enhances workability as a structure in which the reinforcing piece interposed in the core material on the fixed part side is not fixed by the fixture. An object of the present invention is to provide a panel in which a flexible joint member is integrally formed at both ends in the width direction of the panel.

As shown in FIG. 5, the insertion edge 7 is a portion which is inserted into a fitting groove 15 of the female connecting portion 12 to be described later and is fixed to the wall foundation α, and a fixing tool β such as a nail is inserted into the fixing groove 10. And functions as a fixing portion for fixing the panel A to the wall base α. The concave fixing groove 10 is formed to be larger than the height and width of the nail head of the fixing tool β so that the fixing tool β does not protrude above the surface of the basement 5 and engages the panel A. In this case, a gap is not formed in a contact portion between the upper surface 13 and the underground base 5 and the upper edge 8, which will be described later.
A gap is formed by 10 to prevent the capillary phenomenon and enhance waterproofness, and at the same time, from the tip of the insertion edge 7 to the upper edge 8 of the fixing groove 10.

The joint member 23 as shown in FIG. 4 has a hollow portion 24a in the main body 24, substantially at the bottom of the main body portion 24 in a shape that can engage the reinforcing and locking pieces 19, 21 of the backsheet 17 L It is formed in a long shape from an engagement piece 25 and an engagement groove 26 projecting in a letter shape, and has a certain degree of flexibility. More specifically, as shown in FIG. 5, the joint member 23 is formed at the end of the panel A, so that the contact surfaces 24b of the joint members 23 are in close contact with each other at the joint between the panels A, and In addition to improving the waterproof and airtight properties of
1 and 17 , which function as a contact prevention material and a thermal bridge prevention material, and further prevent leakage of the synthetic resin foam raw material serving as the core material 22 during the production of the panel A from the space between the front surface material 1 and the back surface material 17. It functions as a preventive material. Also, the engagement groove 26
Is fixed to the reinforcing and locking pieces 19 and 21 and has a function of positioning the joint member 23 and a function of a fixing groove. The material is a synthetic resin-based or rubber-based extruded material having excellent flexibility, weather resistance, heat resistance, waterproofness, and dimensional stability, for example, soft PVC.

〔The invention's effect〕

According to the panel of the present invention as described above,
The joint member significantly improves the waterproofness and airtightness of the joint. The joint member functions as a leakage preventing material for the synthetic resin foam raw material. Since the joint member has flexibility, waterproofness and airtightness are greatly improved. The joint member improves the dimensional accuracy of the end portion and the construction accuracy. Joint member 1
Thus, it has the functions of a conventional liquid leakage prevention sheet and packing. The thermal bridge between the surface material and the back surface material is eliminated by the interposition of the joint member, the heat insulation is improved, and a dew condensation preventing function is provided. In fixing to the wall base, a portion where the core material and the back surface material are present in the lower layer at one edge of the surface material is fixed, so that the panel is securely fixed to the wall base and does not peel off.
Large panels can be securely fixed to the wall base without exposing nails, bolts, etc. to the outside. Since the middle of the upper edge is depressed in a concave shape along the longitudinal direction and a fixing groove larger than the width of the head of the fixture and the height is formed, the fixture does not protrude from the upper edge, eye underground, Waterproofness, airtightness, and workability can be improved. Since the length of the upper surface is formed longer than the position of the fixing groove, the fixing tool is not exposed to the outside. Even if a slight error occurs in the joint width, the fixing tool is not seen from the outside. The extended portion and the cutout portion formed on the back surface material prevent the rainwater caused by fire, heat, wind and rain, etc., from entering the wall foundation side due to the fire. Since the reinforcing piece formed on the male connecting portion side of the surface material is formed inside the core material, the integration with the core material is ensured, and the strength of the insertion edge against external force is improved. Since the reinforcing piece was formed at a position where it was not fixed by the fixture, it did not interfere with the construction. Since the surface material and the back material do not come into contact with each other even at the connection part, a heat bridge is prevented and fire resistance, heat insulation, and dew condensation resistance are improved. Waterproof, airtight, shockproof,
Panels with improved heat insulation, fire resistance, soundproofing, and workability. There are features and effects such as.
