Description

TECHNICAL FIELD The present invention relates to a resin face material used for walls and the like.

Face materials made of natural stone are sometimes used as finishing materials for exterior walls of buildings and the like. There are wet construction method and dry construction method as construction methods for attaching the face material to the building frame. The wet construction method is a construction method in which the face material is tied to the base with a trigger, and the space between the face material and the frame is filled with back-filling mortar. On the other hand, the dry construction method is a construction method in which face materials are attached to the frame by a method of receiving a load one by one using fasteners. In some cases, a resin face material such as artificial marble is used instead of natural stone. Since this resin face material has a lower density and a higher bending strength than natural stone, the plate thickness can be reduced. Further, since the weight can be reduced, the area per sheet can be increased if the weight is the same. A method for constructing a wall surface of such a resin-made face material has also been studied (for example, Patent Document 1). In the wall construction method described in this document, fasteners having locking portions and fixing portions are fixed to a wall or base (panel), and artificial marble wall materials cut to a predetermined size are attached to both ends or one end. The provided groove is fitted and locked to the locking portion of the fastener.

A method of fixing wall materials using dowel pins is also known (for example, Patent Document 2). In the construction structure described in this document, dowel pins are inserted into dowel holes drilled in the lower surface of the upper side wall material and the upper surface of the lower side wall material, and the dowel pins are engaged with mounting brackets attached to the wall surface of the building frame.

However, if the thickness of the plate is thin, sufficient fixing strength of the dowel pin cannot be obtained. Therefore, a large number of dowel pins are required to withstand external forces such as wind load and seismic load. In this case, the number of mounting fasteners increases, resulting in an increase in cost. Furthermore, since many mounting operations are required, workability is also reduced.

A resin face material for solving the above problems contains a resin and is fixed to a structural member by a dry construction method. a central surface portion having a predetermined thickness; an upper surface portion having a thickness greater than the predetermined thickness; a lower surface portion having a thickness greater than the predetermined thickness; An upper fixing portion provided at the upper end of the face portion, and a lower fixing portion provided at the lower end of the lower surface portion.

INDUSTRIAL APPLICABILITY The present invention can achieve both reduction in weight due to thinness of a large resin panel and reinforcement of a portion fixed to a structural member.

The crosspiece 20 is formed by joining two layers of artificial marble together over the entire length of the upper and lower sides of the resin-made face members P10 and P20 by surface-joining them with a common material. Each artificial marble forming crosspiece 20 has a thickness of 12 mm and a height of 100 mm. The crosspiece 20 on the upper end side is a resin-constituting face material, and together with the resin-made face material, constitutes an upper surface portion that is continuous above the central surface portion. The crosspiece 20 on the lower end side is a resin-constituting face material, and together with the resin-made face material, constitutes a lower face portion that is continuous below the central face portion. The upper and lower surface portions at the upper and lower ends of the resin surface materials P10 and P20 are flush with the central surface portion to form a common surface (edge surface), and are thicker than the central surface portion having a predetermined thickness. .
