Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an insulating construction method for a rooftop waterproof layer in a building, and the present invention relates to a method for insulating a rooftop waterproof layer of a building, in which leg pieces each having engaging uneven portions on opposite side edges are disposed on the rooftop waterproof layer of a building. Brick blocks are laid out vertically and horizontally in such a way that the engaging concave and convex portions of the legs of adjacent brick blocks engage with each other in one direction, and so that the adjacent blocks abut each other in the other direction. It is characterized by filling the joints formed between adjacent bricks with a joint material that solidifies but does not stick to the joints.The purpose of this is to have excellent heat insulation performance, and to make inspections and inspections easier. The object of the present invention is to provide an improved insulation construction method for a rooftop waterproof layer that is easy to repair.

In the present invention, as described above, a waiting space is formed between the main body of the brick blocks having insulation properties arranged vertically and horizontally on the waterproof layer of the building and the waterproof layer, and the air in the space and the outside air are naturally connected. Since the air circulates and cools the building frame, it is ideal for preventing hot weather, and since the air circulates in this way, there is no risk of condensation.

Furthermore, the brick block has opposing edges on both sides.
Leg pieces each having an engaging concave and convex portion are provided, and the blocks are arranged vertically and horizontally so that adjacent brick block leg pieces engage with each other in one direction, and so that adjacent blocks abut each other in the other direction. laid out in
A solidifying but non-adhesive joint material is filled only in the joints formed between adjacent brick blocks in one direction, and a heat insulating structure made of brick blocks is thus formed by the dry construction method. Therefore, if there is an accident with the waterproof layer, the brick blocks can be removed in order starting from the end. Inspection and repair of layers can be easily performed.

Furthermore, according to the present invention, the leg pieces of adjacent brick blocks are engaged with each other via the engagement uneven portions, so that
There is no risk of brick blocks being blown away during typhoons.

The present invention will be described below with reference to the illustrated embodiments.

Reference numeral A denotes a brick block, and a leg piece 2 having engaging concave and convex portions 2a and 2b on the outer surface is hung from the opposite side edges of a rectangular main body 1. Note that an intermediate leg piece 3 is hung from the middle of the opposite opposite side edges of the block body 1, and enlarged parts 2c and 3a are provided at the bottom of each of the leg pieces 2 and 3, and the lower part of the brick block A, which will be described later, is It is designed to evenly press the cushion material and prevent damage to the waterproof layer.

Then, a waterproof layer D is layered on the leveled mortar layer C on the roof frame concrete B of the building, and a cushion material E for unevenness adjustment and protection of the waterproof layer is layered on the waterproof layer D. In this case, by forming the cushion material E from a hard urethane foam, the heat insulation properties are further improved. Next, the brick blocks A are laid out horizontally and vertically on the cushion material E, and the engaging concave and convex portions 2a and 2b of the leg pieces 2 and 2 of adjacent brick blocks A are engaged with each other in one direction, and the engaging concave and convex portions 2b of the leg pieces 2 and 2 of adjacent brick blocks A are engaged with each other in the other direction. Match the adjacent block bodies 1 and 1,
The joints formed in one direction are filled with a joint material F that hardens but does not stick.

When the joint material F is inserted into the joint, it expands and fixes when it comes into contact with air, filling the joint, but since it has no adhesive properties, the block can be removed. As such a joint material F, for example, Compliform (product name: manufactured by Nitto Boseki Co., Ltd.) is used.

Since the illustrated embodiment is configured as described above, air is formed between the block body 1 and the cushion material E by the leg pieces 2 and 3 of the brick block A, and the air in the same space and the outside air are formed between the block body 1 and the cushion material E. Naturally circulates to air-cool the frame B, and this air circulation prevents dew condensation.

In addition, the adjacent brick blocks A are engaged with the engagement uneven portions 2a and 2b of the respective leg pieces 2, and the joints are filled with a joint material F that hardens but does not have adhesion properties. Therefore, if an accident occurs in the waterproof layer, it is possible to remove the brick blocks A in order starting from the ends, and inspection and repair can be easily performed. In addition, since the engaging concave and convex portions 2a and 2b of the leg pieces 2 of adjacent brick blocks A are engaged,
There is no risk of Block A being blown away by a typhoon or the like.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various ways without departing from the spirit of the present invention. .
