In general, in the case of a concrete skeleton that is often constructed as an underground outer wall, many steps are required, such as rebar work, formwork work, concrete work, formwork dismantling work, waterproofing work, and heat insulation work.
In addition, a work space of about 1 m to 1.5 m is required between the underground outer wall and the mountain retaining, and the amount of excavation and backfilling of the soil increases.
Therefore, by using formwork concrete blocks on the underground outer wall and constructing it from the inside, the construction process is reduced, the working space around the outer wall is reduced to about 150 to 200 mm, and the amount of soil excavation and backfilling is greatly reduced. Things become possible.
The present invention provides a heat-insulating waterproof structure that integrates a waterproof material and a heat-insulating material that can be laid on an underground outer wall even in a narrow work space, a heat-insulating waterproof material used for this heat-insulating waterproof structure, a tool, and a heat-insulating waterproof structure. It is intended to provide a construction method for laying.

The heat-insulating waterproof structure of the present invention is constituted by a plate-like heat insulating material to which an adhesive sheet-like waterproof material is adhered. By attaching a soft sheet-like waterproof material to the plate-like heat insulating material, it becomes possible to lower the inside of the basement from the upper part straight into the gap between the mountain retaining and the basement outer wall. By stacking formwork concrete blocks according to the size of the heat insulating material, it can be repeatedly constructed on the upper part.
The overlap of the seam portion of the waterproof sheet is secured by shifting the adhesive sheet-like waterproof material to the heat insulating material and pasting it twice. In addition, a handle at the time of construction and a protrusion which is a hit when the next step of the insulation and waterproofing material is constructed are provided at the front upper part of the insulation material.

The invention expands the possibility of constructing formwork concrete blocks on underground outer walls. In addition, the construction period can be simplified and shortened, and construction costs can be reduced.

It is a figure showing the construction method of an embodiment. It is a figure showing the construction method of an embodiment. It is a figure showing the construction method of an embodiment. It is a development view and a sectional view showing one embodiment of a construction method of a heat insulation waterproofing structure of the present invention.

Hereinafter, a method of installing a heat-insulating waterproof material and a heat-insulating waterproof structure according to an example of an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a configuration of a heat insulating and waterproofing material according to the present embodiment. 1 (A) is a front view of the heat-insulating waterproof material, FIG. 1 (B) is a cross-sectional view of the heat-insulating waterproof material, and FIG. 1 (C) is a drawing of the bonding surface of the heat-insulating waterproof material.

As shown in FIG. 1 (A) to FIG. 1 (C), the heat-insulating and waterproofing material of the present invention comprises a plate-shaped heat-insulating foam material 1 and a handle portion 2 and a viscous material adhered to the back surface of the plate-shaped heat insulating material. It comprises a waterproof sheet 3 and a waterproof sheet 4 having two layers. The waterproof sheet 4 is stuck on the waterproof sheet 3 or on the left or right side by about 100 mm. This is the basic member of the heat insulating and waterproofing material of the present invention.

As the material of the plate-shaped heat insulating material 1 and the handle part 2, for example, materials (bead method polystyrene foam heat insulating material, extrusion method polystyrene foam heat insulating material, rigid urethane foam heat insulating material) indicated in JIS A9511 (foamed plastic heat insulating material) Materials, polyethylene foam insulation material and phenol foam insulation material) and calcium carbonate foam board. The length of the short side of the heat insulating material is, for example, 600 to 1000 mm, but it is considered that about 600 mm is preferable in consideration of workability. The length of the long side is, for example, 600 to 2000 mm. The thickness depends on the required heat insulation performance, but is, for example, 20 to 100 mm.

The handle portion 2 is attached so as to protrude from the plate-shaped heat insulating material 1 and serves as a clue for lowering the inside of the basement from the upper portion straight into the gap between the mountain retaining and the basement outer wall. It is necessary to lower the insulation and waterproof material slightly away from the outer wall so that the adhesive surface does not touch the outer wall of the basement. At this time, the protruding handle portion 2 comes into contact with the next heat insulating material 1.

As a material for the waterproof sheets 3 and 4, a viscous material is suitable, for example, a butyl rubber sheet or a modified asphalt sheet. Both have strong adhesiveness so that they can be easily and tightly adhered to the substrate and can be expected to have reliable waterproofing performance. By shifting the 100mm waterproof material to the top and left or right and sticking it twice, it corresponds to the waterproof seam.

2 to 4 are views showing a construction method according to the present embodiment.

As shown in FIG. 2 (a), the waterproof sheet 4 made of a heat-insulating waterproof material is installed so as to hang on the first step of the formwork concrete block 5. The formwork concrete blocks are piled up from the inside by the height of the insulation. FIG. 2 (b) shows a state in which formwork concrete blocks 5 having a height of 200 mm are stacked from the second stage to the fourth stage, with the height of the heat insulating material being 600 mm as an example. As shown in FIG. 2 (c), hold the handle portion 2 and lower it straight from above into the gap between the mountain retaining and the outer wall of the basement. At that time, it is necessary to lower the heat insulating and waterproofing material slightly away from the outer wall so that the adhesive surface does not touch the outer wall of the basement.

As shown in FIG. 3D, the protruding handle portion 2 hits the heat insulating material 1. After that, the entire insulation and waterproofing material is drawn toward the formwork concrete block. As shown in FIG. 3 (e), after bonding to the formwork concrete block, it is sufficiently pressed from above by a rubber roller or the like. Then, formwork concrete blocks are stacked again from the inside by the height of the heat insulating material. FIG. 3 (f) shows a state in which formwork concrete blocks 5 having a height of 200 mm are stacked from the fifth stage to the seventh stage, with the height of the heat insulating material being 600 mm as an example.

After that, as shown in FIG. 4 (g), the user again holds the handle portion 2 and lowers it straight from the upper portion into the gap between the buckle and the outer wall of the basement. Similarly, the entire heat insulating and waterproofing material is drawn toward the formwork concrete block side (FIG. 4 (h)), and after being bonded, it is sufficiently pressed from above by a rubber roller or the like (FIG. 4 (i)). This step is repeated.

FIG. 5 (D) is a view of the embodiment of the present invention as viewed from a mountain retaining side. In particular, the heat-insulating and waterproofing material at the inner corner portion or the outer corner portion 10 is applied first. The waterproof sheet 4 at the inner corner portion or the outer corner portion 10 is shifted by about 100 mm above the waterproof sheet 3, and is stretched by about 100 mm on both the right and left sides and attached. After that, the basic heat insulating and waterproofing material is applied by shifting each stage by half. At the end of each step, the remaining part is cut off from the heat insulating material pasted up to the waterproof sheet 3 at the site, and a waterproof sheet 4 shorter than the waterproof sheet 3 by about 100 mm on both the left and right sides is applied.

FIG. 5E is a cross-sectional view of the embodiment of the present invention. After stacking the formwork concrete blocks 5 and applying insulation and waterproofing materials, concrete 7 is poured into the slab and the formwork concrete. At that time, the release paper of the adhesive surface of 100 mm above the uppermost waterproof sheet 4 is left. After that, concrete 8 is poured into the gap between the mountain retaining and the heat insulating material or backfilled with high quality soil, but it is more preferable to put the concrete in view of protection of the heat insulating material. The insulation on the ground is protected by mortar 9. Lastly, peel off the release sheet of the waterproof sheet 4 that has been left, and attach it to the upper part of the concrete block in which concrete has been cast.

INDUSTRIAL APPLICABILITY The present invention is expected to be used mainly when a small basement is provided in a building such as a wooden structure or a lightweight steel frame. In particular, since the excavation area is small, utilization on a small site is expected. The materials used are also commercially available, such as concrete concrete blocks, foam insulation, and sticky waterproof sheets such as butyl rubber and modified asphalt sheets. In addition, work can be performed not only by special works such as formwork, reinforcing steel work, and waterproofing work, but also by general works, and can be performed at relatively low cost.
