Description

[Detailed Description of the Invention] This invention relates to a protection device in which light-shielding heat insulating plates are laid out on a roof surface, particularly a flat roof surface on which a waterproof layer is formed.

Conventionally, light shielding heat insulating plates such as concrete plates are laid on the roof surface with gaps between them and the edges of each plate to protect the roof surface and prevent damage to the waterproof layer and deterioration due to sunlight, exposure, etc. Furthermore, the open air layer improves heat insulation.

However, in order to arrange a board material such as a concrete board on the roof surface in this way, it is necessary to provide legs on the bottom surface of the board material and fix it by fitting into a fitting groove provided on the roof surface, or to form protrusions on the roof surface. They were arranged by placing and fixing plate materials on this. These methods require time and effort to form fitting grooves and protrusions on the roof surface.
In addition, it is difficult to lay out the planks accurately while keeping gaps between them, and positioning and fixing them requires a lot of effort.

This idea was created by focusing on the above problem, and its purpose was to maintain a gap between the light shielding heat insulating board and the roof surface, and also to create a gap between the end faces of the boards. To propose a roof surface protection device that can be installed accurately and easily.

This will be explained below with reference to the illustrated embodiments.

In FIG. 1, a jointer 1 is arranged with a predetermined gap on the roof surface, has a rectangular parallelepiped shape, and has one guide protrusion at the center of the upper surface, with the guide protrusion 2 aligned parallel to one direction. Waterproof layer 3 formed on the roof surface
is attached with adhesive. 1 joiner 1
The four corner parts of four square light-shielding insulation boards 4 made of lightweight concrete plates are placed and lined up from four directions on top, and disk-shaped presser caps 5 are placed over the corner parts. The light-shielding and heat-insulating plate 4 is fixed by locking it to the joiner 1 with a stopper.

In FIGS. 2 and 3, the joiner 1 is an extrusion molded product of hard vinyl chloride resin, and has a rectangular parallelepiped main body 6 with square upper and lower surfaces, and one side (side surface along the extrusion direction) at the center of the upper surface. It consists of a rectangular parallelepiped guide protrusion 2 protruding parallel to the guide protrusion 2, and a screw hole 7 is bored in the center of the upper surface of the guide protrusion 2. In addition, two parallel elastic protrusions 8, 8 made of plastic are fixed to both sides of the guide protrusion 2 on the upper surface of the main body 6, and base plates 9, 9 made of soft vinyl chloride resin are attached to the lower ends of both sides of the main body 6. are aligned flush with the lower surface of the main body part 6 and fixedly integrated with the main body part, and are adhered to the waterproof layer 3 with an adhesive.

The light-shielding heat insulating board 4 has two rectangular parallelepiped notches 10 and 1 at the corners, which are open in the upper and lower surfaces and in the direction of the two end surfaces, and are cut out in two planes parallel to the two end surfaces, respectively.
0' are provided partially overlapping each other, and the dimensions of the two plane sides are slightly smaller than 1/2 of the length and width of the guide protrusion 2. Further, a 1/4 arc-shaped concave portion 11 is provided at the corner portion of the upper surface, and the protruding corner portion formed by the two overlapping notches 10 and 10' is an oblique notch surface.

This light-shielding heat insulating board 4 has two orthogonal side wall surfaces of one notch 10 attached to two side wall surfaces forming the corner of the guide ridge 2 of the joiner 1 fixed on the roof surface. It is placed on a positioning jointer main body 6, and four light-shielding heat insulating plates 4 are arranged on one jointer 1 from all sides with the corner portions centered around the screw holes 7. The light shielding heat insulating board 4 is the guide protrusion 2
and positioned by the dimensions of the notch 10,
They are arranged with a predetermined gap between their end faces, and the gap with the roof surface is maintained by the height of the joiner main body. Although two notches 10 and 10' are provided at the corner, it is not necessarily necessary to provide two notches; one notch may be sufficient.
If two are provided, the directionality of the light-shielding heat insulating plates can be freely determined, and workability in arranging and arranging them will be improved.

Place the disc-shaped presser caps 5 in the concave portions 11 at the four corners of the light-shielding heat-insulating plates 4 laid out in this manner, and screw the screws 12 into the screw holes 7 from the center hole to attach the corner portions to the joiner body. A roof surface protection device is formed by tightening and fixing on the part 3.

In addition to the light-weight concrete board used in the example, the light-shielding insulation board used in this invention can be made of synthetic resin, concrete, a board made of glass fiber, steel fiber, etc., and other water-resistant and fire-resistant boards. The length of one side is 30~
It is about 90cm square.

This idea is as described above, and the two orthogonal side wall surfaces of the rectangular parallelepiped-shaped notch, which is open in the upper and lower directions and the two end surfaces provided at the corners of the light shielding heat insulating board, are rectangular guide projections with a rectangular cross section on the upper surface of the joiner. By attaching and positioning the strip to the two orthogonal side wall surfaces, and making the planar dimensions of the notch portions slightly smaller than 1/2 of the length and width of the guide protrusion, the light-shielding heat insulating plate can be positioned between the mutual end surfaces. The gap can be easily and accurately set to a desired size, and at the same time, a gap can be provided between the roof and the roof surface that is equal to the height of the top surface of the joiner. In addition, there is no need to form fitting grooves or protrusions to lock the board on the roof surface as in the past, and the corners can be covered with presser caps and fixed with screws, etc., improving construction efficiency. can. Since the jointer can be manufactured by extrusion molding using a synthetic resin such as hard vinyl chloride, the cost is low and the length dimension can be freely selected, which is convenient.

In addition, if an elastic protrusion is provided on the main body of the jointer and a light-shielding heat insulating plate is placed in contact with the elastic protrusion as in the example, the impact received by the plate material can be alleviated and damage to the plate material can be prevented, and the base plate can be If it is provided at the lower end of the side surface, it is effective in protecting the adhesive layer on the bottom surface of the jointer and maintaining the adhesive strength over a long period of time.
