Abstract

PURPOSE:To perform the work safely and efficiently by a method wherein a plurality of laminated sheet materials consisting of a heat insulating layer, a strength retaining material layer and a water proof sheet layer are employed and the joint parts of the waterproof sheet layers abutted each other toward the inside of a heat accumulator are covered by band waterproof sheet in order to theremally fuse the waterproof sheets. CONSTITUTION:A plurality of rectangular laminated sheet materials 10 formed by a heat insulating layer 12, a strength retaining material layer 14 and a waterproof sheet layer 16 are assembled under the ground of a building so as to use themselves as the mold of a heat accumulator and to pour concrete 20 onto their outer peripheries in order to solidify the concrete to form the heat accumulator 30. After that, the joint parts of the abutted laminated sheet materials are covered by band waterproof sheet 18 in order to fuse both the layer 16 and the waterproof sheet 18 by heating by means of a heated air generator and, after that, pressing the heated portion with a hand roller. Consequently, no harmful gas generates during working and efficient implementation can be realized under favorable working environment.

の空気中に放出づることによって行なわれる。tJIUi Recently, the 7-1 pump system is rapidly becoming popular as a dual purpose heating and cooling device in buildings. Air conditioning and heating using a heat pump uses a medium called fluorocarbon gas to pump up heat from the air either inside or outside the building with a compressor and release it into the air.

悪いものとなる。However, the capacity of the air conditioning system depends on changes in temperature inside and outside the building, and it is necessary to select the capacity of the system to meet the maximum human load. However, in this case, the equipment is often operated under partial load conditions, resulting in very low efficiency.

さくすることができる。On the other hand, in a regenerative heat pump system that combines a heat pump and a heat storage tank, the heat pump is operated outside of air conditioning hours (by doing so, the heat is stored in the heat storage tank, and the heat can be used for air conditioning, so it is very easy to use). Efficient operation can be performed, and the capacity of the P1 pump can be made smaller than that of the former.

The structure is generally constructed by forming the bottom wall, side walls, and roof walls of concrete structures, providing a layer of insulation material on the inner surface, and applying waterproofing treatment to the surface of the insulation layer. It is true. The waterproofing treatment of the heat storage tank is carried out by a mortar waterproofing method, a paint film waterproofing method, a seal/waterproofing method alone, or a combination thereof.

部を密封するだ（プで良い。The laminate used in the present invention is formed of a heat insulating material layer, a reinforcing material layer, and a waterproof sheet layer, and since split bamboo is provided in the reinforcing material layer, this is used as a formwork for concrete 1 to pouring. This method significantly reduces the number of man-hours and improves work efficiency compared to the conventional construction method in which a concrete one-structure wall is formed in advance and then the inner wall is subjected to heat and waterproof treatment. In other words, in TF Lapo, which has formed concrete walls from concrete 1 to structural walls by using laminates in formwork, a heat insulating VJ layer and a waterproof layer from 1 to 1 have already been attached to the inner walls, and after that, each laminate is Seal the joint.

A plurality of laminates consisting of layer A, a strength material layer and a waterproof sheet layer are used, and a strip-shaped waterproof sheet of the same size of 4A''jA is heat fused to the waterproof sheet layer at the joint where the laminates are joined together. As a result, the sealing is highly reliable and semi-permanent waterproofness is guaranteed.There is no gas generation during the honeymoon work, ensuring worker safety and allowing efficient work in a good working environment. In addition, by using the rigidity of the reinforcing material layer, it is possible to use the laminate itself as a formwork to drive the concrete 1 to the outer periphery, so that the waterproof sheet can be pasted afterwards. Combined with the fact that it is not necessary, the number of man-hours is greatly reduced, and the cost becomes cheaper.
