[0003]

When the above panel is made of wood, not only the weight becomes heavy but also there is a disadvantage in terms of durability such as rot due to long-term use. Since the panel is provided, the panel itself becomes large in size, and there is a disadvantage that the weight becomes heavier. or,
When carrying or installing a large sealed box-shaped panel, it is difficult to grasp a thick flat panel, which is disadvantageous in terms of handling. In addition, at least two types of panels, that is, a floor panel in which a hot water pipe is arranged inside the outer frame member and a panel in which a conduit tube is provided inside the outer frame member must be manufactured, which is disadvantageous in terms of cost. Was there. Also, since the hot water pipes and conduits are buried inside the panel, it is not possible to grasp the condition of the pipes, and it is difficult to replace the damaged pipes, and the panel itself is replaced. Therefore, there is a disadvantage that the cost becomes high.

In view of the above-mentioned situation, the present invention is to solve the problems while suppressing an increase in weight.
It is an object of the present invention to provide a plastic panel for construction which is excellent in strength, is easy to handle, and is advantageous in terms of both cost and maintenance.

[0005]

In order to solve the above-mentioned problems, the building plastic panel of the present invention is provided with hollow first reinforcing portions which are substantially rectangular in plan view at both ends in the left-right width direction. , A large number of hollow second reinforcing portions that are substantially rectangular in plan view are provided in the middle portion in the left-right width direction without gaps along the left-right width direction, and the first reinforcement portions and the first reinforcement portions located at both ends thereof. Between the respective reinforcing portions, the second reinforcing portions located in the middle portion opposite to each other in the left-right width direction are opened in the same direction as the panel thickness direction, and the electric wire storage portion and the electric wire are provided over the entire panel length direction. A recessed groove for forming at least one of a pipe storage portion, a hot water pipe storage portion, and an air conditioning pipe storage portion is provided, and a cover member for closing the recessed groove from the panel thickness direction is removed from the recessed groove. Provided freely, the first reinforcing portion Beauty inside of the second reinforcing portion is characterized by being filled with foam. By using plastic as the material of the panel, it is possible to reduce the weight as compared with the case where the panel is made of wood. By providing the substantially rectangular and hollow first reinforcing portion and a large number of second reinforcing portions, it is possible to improve the shape retention strength while achieving weight reduction. Further, by filling the inside of the first reinforcing portion and the second reinforcing portion with a foam material,
Not only can a heat insulating layer be provided, but also the shape retention strength of the panel can be dramatically improved. Also, the first
The recessed groove formed between the reinforcing portion and the second reinforcing portion can be grasped to move the panel quickly or perform construction. Moreover, the concave groove is used to store the electric wire storage portion, the conduit pipe storage portion, the hot water pipe storage portion,

It is preferable to use polyurethane as the foam material.

The left and right corners of the second reinforcing portion on the concave groove side and the corners of the first reinforcing portion that oppose to these are formed with protrusions protruding in the left-right direction, and the cover member is provided with the protrusions. By providing the projecting portion with the locking portion capable of locking and holding, the cover member can be quickly attached and detached by the locking, as compared with the case where the cover member is attached and detached using a screw or the like.

When the building plastic panel is used as a floor panel, the panel is placed in a posture in which the open side of the groove is the upper surface, and the cover member is the first reinforcing member forming the groove. Section and a pair of left and right vertical plate portions that are substantially parallel to the surfaces of the side plate portions of the second reinforcing portion, and a connecting plate portion that connects the base end portions of these vertical plate portions, the cross-sectional shape is U-shaped, In the mounted state of the cover member, a connecting plate part that forms the recessed groove by connecting the end plate of the vertical plate part to the side plate parts of the first reinforcing part and the second reinforcing part in a direction orthogonal to the plate thickness direction. The dimension of the vertical plate portion is set so as to be in contact with the surface of the vertical plate. As described above, when the cover member is attached, since the front end surface of the vertical plate portion of the cover member is in contact with the surface of the connecting plate portion that forms the concave groove, the cover member is large in strength. Even if a pressing force is applied, the cover member is less likely to be deformed.

When the hot water pipe is housed in the groove,
By covering the other surface of the surface of the hot water pipe excluding the surface on the cover member side with a heat insulating member made of a foam material, it is possible to suppress a decrease in the heat insulating effect of the panel in the groove and to prevent the heat water pipe from the hot water pipe. The heat radiation can be efficiently transmitted to the cover side. When the cover member is made of metal having a high thermal conductivity, the heat from the hot water pipe can be more efficiently transferred to the floor side than the cover member made of synthetic resin.

Moreover, since the direction changing guide member includes the heat insulating layer formed by filling the inside of the substantially rectangular tubular portion with the foam material, the heat insulating performance of the direction changing guide member located between the panels is improved. Not only can it be prevented from falling, but the shape retention strength of the direction changing guide member can be increased.

By lowering the heat insulating performance in the groove by providing a heat insulating layer on the inner surface side of the cover member and the cover portion so as to fill a part of the groove and to insulate the inside of the groove. Not only can it be suppressed,
It can function as a cushioning material.
