Description

Description: TECHNICAL FIELD The present invention relates to an outer insulating roof structure for a flat roof, a gently sloping roof, or the like.

[Problems to be Solved by Prior Art and Invention]

The development and implementation of external heat insulating roof structures are increasing to save energy and improve habitability of buildings. The applicant has previously proposed that the heat insulating composite block be mounted on the flat roof of a concrete building so as not to fly by the wind.
7434 and Japanese Utility Model Laid-Open No. 58-17435 have been developed, and they are constructed by attaching each heat insulating composite block with a stopper having a sandwiching plate at the top and bottom.

By the way, when a concrete flat roof is made of cast-in-place concrete, a non-terrain condition often occurs. Therefore, in the case of attaching to the stopper, the unterrain appears as it is on the upper surface of the composite block,
The composite block may rattle, or part of the water may be trapped on the roof below the composite block, water may splash when walking on the roof, or this water may gradually penetrate into the concrete flat roof. There is a lot of work required for installation work by.

The present invention was developed to solve the above problems.

[Means for Solving the Problems]

This invention is a composite block in which a lower synthetic resin foam plate and an upper mortar plate are integrated, and a lower surface of the synthetic resin foam plate and concave portions are formed in four gaps, and a bulky structure with a predetermined interval on the roof upper surface. And the composite blocks are laid and arranged on the roof upper surface, and the adhesive material enters the recesses on the lower surface of the synthetic resin foam plate, and the adjacent recesses form a group of adhesive materials. The outer heat insulating roof structure is characterized in that a heat insulating layer having a uniform upper surface of the composite block is formed on the roof upper surface as a whole. The details will be described below with reference to the illustrated embodiment.

〔Example〕

FIG. 1 shows a cross section of the outer insulating roof of the present invention.

In the composite block A, the lower synthetic resin foam plate 1 and the upper mortar 2 are integrated, and the recesses 3 are formed at the four corners of the lower surface of the synthetic resin plate 1.

The roof 4 is made of a reinforced concrete slab provided with a waterproof layer 5, and an adhesive material 6 is bulged into a bulky or dango-like shape on its upper surface at a predetermined interval, and a composite block A is pressed and laid on the adhesive material 6 to form a synthetic resin foam board. 1. Adhesive material 6 is made to enter the concave portion 3 on the lower surface of 1 and adjacent concave portions 3, 3
They are connected to each other with a group of adhesive materials. As a result, even if the upper surface of the roof 4 is in a non-landing state, the bulky adhesive material 6 is deformed so that a gap is created between the roof 4 and the composite block A. A uniform heat insulating layer is formed so as to be flush with.

The position where the adhesive material is raised in bulk may be either a position where individual recesses are arranged on the roof, a central part where a plurality of adjacent recesses are arranged, or a recess position of the composite block A. The point is that a composite block laid with noble adhesive material is pressed to make it enter the recess, and at the same time, it is not a group that spans multiple recesses, the recesses are connected, and the block top surface is a uniform surface. Just align.

Various embodiments of the composite block A are shown in FIG.

This composite block is width, length 450mm, thickness mortar board is fiber strength cement mortar board, asbestos board and other inorganic molded board that can withstand human walking, and thickness is 15
The synthetic resin foam plate is made of polystyrene or polyvinyl chloride such as Styrofoam "trade name, manufactured by Dow Kako Co., Ltd." and has a thickness of about 25 to 50 mm.

The shape of the concave portion 3 is an arc dovetail groove shape in FIGS.
8-15, b; 10-25, c; b + 10-25, d; 4
It is 0 to 70 (unit: mm).

In FIGS. 4 to 5, the outside of the dovetail-shaped recess 3 is open, and a; 8 to 15, b; 40 to 70, c; b + 5
It is 10 (unit: mm).

In FIGS. 6 to 7, the concave portion 3 has a circular dovetail shape, and a;
~ 20, b; 10-30, c; b + 5-15 (unit mm)
Is.

“The composite block A shown in FIGS. 6 to 7 has a shape in which the recesses 3 do not open to the side surfaces of the corners. In this case as well, a group of adhesives having a size that spans the four recesses 3 in the corners of the composite blocks laid out side by side. The material is heaped up on the upper surface of the roof, the upper part of the adhesive material is made to enter the respective concave portions 3, and a group of the adhesive materials is used as a connecting material to be connected to each other to form a heat insulating layer having a uniform upper surface. It can be formed. ”As a dango-like adhesive material, a room temperature-curable aliphatic or aromatic amine curing agent or a polyamide curing agent is added to an epoxy resin which is a basic epoxy resin adhesive. In addition, powdered fibers and the like are mixed as a filler. Other urethane resin adhesives can be used.

The bulky adhesive has a thickness of 3 to 30 mm and a diameter of 40.
Approximately 50 mm in diameter and crushed to a diameter of 60 to 12
It will be about 0 mm.

〔The invention's effect〕

Since the present invention has the above-mentioned structure and the adhesive material is bulged up on the roof top surface, it is easy to press the composite block so that the top surface of the composite block becomes flat even if the roof surface is uneven. Can be pasted. In addition, there is a recess in the corner of the composite block, and the adhesive material enters into this area and is anchored, and the adhesive material forms a group and serves as a connecting material to connect the adjacent composite blocks, and at the same time, fix the block to the roof top surface. Since it is fixed to the roof, the composite blocks are also connected to each other, and there is no fear of flying by the wind.
