Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 It is a well-known fact that underground buildings have traditionally been excellent in heat insulation and airtightness.However, in the present invention, underground buildings with excellent moisture proof, heat insulation and airtightness are set at low prices. And provide it to society widely.

[0002] In addition, the present invention provides a heat insulating effect, a waterproof effect, and a moisture-proof effect, which are the characteristics of the present invention, and also has an airtightness of the underground structure. It can be provided.

Next, several examples of underground buildings will be introduced. Agricultural storage warehouses with room temperature set at 4 ° C to 15 ° C and humidity set at 60% to 70% can be built without using mechanical equipment.

Further, by setting the room temperature to 0 ° C. to −1 ° C., the airtightness of an underground building can be exhibited as a food aging storage warehouse or ice temperature warehouse for aging meat, wine, and the like. The carbon dioxide storage warehouse can be built as a storage warehouse for fruits such as apples and oranges.

[0005] As described above, the technologies that can be used in a wide variety of applications show that the running cost is greatly reduced due to the good heat retention, waterproofness, moisture proofness, and airtightness, and therefore, fresh food can be provided at any time. In addition, it can contribute to cost reduction of distribution products.

[0006]

[Prior art]

 Underground buildings in Japan are mainly constructed on the basement floor of buildings, such as restaurants, water receiving tanks and miscellaneous drainage tanks, machinery rooms, and underground parking lots.

[0007] In Japan, the following can be considered as a reason for constructing an underground building for such a use.

[0008] (1) In constructing an underground building, the cost and difficulty of civil engineering construction are hindering its progress.

[0009] Accordingly, in a building where the construction cost is relatively expensive, the building is constructed in consideration of the foundation of the building itself and the balance of the whole building, but it is not generally used for other purposes. It is the current situation.

[0010] (2) Although the underground structure is excellent in heat insulation and airtightness, since no measures are taken against the moisture-proof surface and no countermeasures are taken, there is a possibility that the construction of the underground structure is hesitant in terms of hygiene against mold and germs. Many are seen.

As a countermeasure for waterproofing and moistureproofing according to the conventional technology, a method of waterproofing with a waterproof mortar or the like after the construction of an underground building is mainly used, but there is a problem with the lack of durability. Therefore, it can be regarded as a risky construction method not only as a living space but also as a food warehouse.

[0012]

[Problems to be solved by the invention]

 The reasons for the high cost and difficulty of civil engineering construction in the prior art (1) are the foundation work and the concrete placement work on the basement.

In carrying out this work, excavation work on the basement, earth retaining work, crushed stone work (including pile driving, compaction, etc.), formwork and foundation work, formwork removal work after concrete placement In addition, there is removal work of earth retaining sheet pile.

[0014] These works are all difficult works, but in particular, the removal of earth retaining sheet piles and formwork after the concrete is cast requires human life and is of high difficulty. It is construction.

[0015] Furthermore, it is necessary to take measures against moisture-proof surfaces by groundwater and rainwater. Countermeasures against these are defined as one of the tasks to provide an underground space with excellent hygiene environment, as it will respond to the growth of mold and germs.

[0016] By solving these problems, various general-purpose technologies can be established, such as a warehouse for storing agricultural products, a warehouse for aging food, an ice temperature warehouse, and a carbon dioxide-filled warehouse, as well as conversion to living space.

[0017]

[Means for Solving the Problems]

 In the present invention, in order to solve the above-mentioned problems, a foamed frame material is used, and a foamed heat insulating plate is laid on a part or the whole of the bottom of the concrete floor.

In addition, a waterproof sheet is to be adhered to the entire outer side surface of the foamed frame material, and furthermore, a top surface on which crushed stone ground (including pile driving, pressurizing, etc.) has been applied, and A resin film is to be spread between the foam insulation board to be laid.

[0019]

Embodiment 1 An embodiment of the present invention will be described with reference to the drawings. 1 is a cross-sectional view showing an underground building, FIG. 2 is a plan view showing a part of the underground building, FIG. 3 is a partially detailed cross-sectional view of a portion Z in FIG. 1, and FIG. Fig. 5 shows a comparison between the indoor humidity 3 and the indoor humidity 3 and Fig. 6 shows a comparison between the indoor humidity 5 and the indoor humidity 6 in the underground building. It is a chart showing the comparison.

After excavating a part to be an underground building, earth retaining work is performed, crushed stone work G (including pile driving, compaction, etc.) is performed, and a resin film K is spread.

[0021] The foam insulation board L is laid on a part or the entire surface corresponding to the bottom of the soil concrete N, the soil reinforcement M is applied, and concrete is poured, whereby the soil concrete N is completed.

While constructing the side wall reinforcement D and the partition reinforcement, the foam outer wall frame material A and the foam partition shape frame material T are set, concrete is cast when the underground building room X is represented, and the exterior wall concrete B is formed. The partition concrete S is expressed.

Further, after cleaning the outer surface of the foamed outer wall frame material A, a waterproof sheet C is adhered to the entire outer side surface, and when the earth retaining sheet pile is removed, backfilling is performed to form the underground building room X.

FIGS. 4 and 5 show data obtained by constructing an underground building as a constant temperature warehouse using the present invention as a table. FIG. 4 shows the relationship between the outdoor temperature 2 and the indoor temperature 3 of the underground building. FIG. 5 shows a comparison between outdoor humidity 5 and indoor humidity 6 in an underground building.

The above data was obtained at our company's apartment and heat insulation warehouse construction site at 4-712 Hachijo 2-Jo Higashi 4-chome, Nishi-ku, Sapporo, Hokkaido, from February 1st, 1998 at 18:00 to February 8th. The data was obtained at 18:00 on the day, and the measurement was performed using two recording temperature / humidity meters OT-104 manufactured by Ota Shoji Co., Ltd.

During the data collection, as a notable matter in FIG. 4, although the outdoor temperature 2 recorded −14.7 ° C. from 6:00 to 9:00 on February 6, the temperature in the underground building room / temperature 3 is that the temperature in the underground building and room temperature 3 recovers smoothly as the outdoor temperature 2 rises without dropping below -1 ° C, and the temperature difference shows 14 ° C.

In addition, since the data was collected during the construction of the ground floor, which is the building construction site of the apartment and heat insulation warehouse owned by the Company, the concrete on the first floor slab, which is the ceiling of the underground building, was also cast. With the temporary sheet just completed, it is almost as if outdoors.

In order to complete the apartment, the roof of the thermal insulation warehouse considers the method of shutting off the outside air with heat insulating material. Fig. 6 shows the results of a temporary measurement of a 900 mm square simulated test chamber with the sides and top excluding the bottom covered by a 50 mm heat insulating material, from 18:00 on February 13 to 18:00 on February 16 It is.

Therefore, when the ground floor is completed, the improvement of these data numerical values will be clearly shown. In addition, as can be seen from FIG. 5, the comparison between the outdoor humidity 5 and the underground building interior humidity 6 shows stable fluctuation values in the range of 10% to 15% regardless of the fluctuation of the outdoor humidity 5.

[0030]

[Effect of the invention]

 In the past, plywood panels (concrete panels) have been the mainstream for formwork used in building construction, and work has been inevitably required to peel and remove the formwork after casting concrete.

[0031] The main material of these plywood panels is wood, and natural destruction due to the deforestation of forest resources has been regarded as a problem worldwide today. However, in the present invention, a panel made of wood products is used. Since it does not use natural resources, it is effective for protecting natural resources such as forest resources.

[0032] In addition, since it is not necessary to remove the formwork after the concrete is cast, the industrial waste can be greatly reduced, and the reduction of illegal dumping of industrial waste can be promoted.

Further, since no formwork removal work is required in the construction process, the number of personnel was significantly reduced, and thus the construction cost was significantly reduced.

Next, after crushing ground work (including pile driving, compaction, etc.) is performed, a resin film is laid, and a foam insulating plate is laid on a part or the entire surface corresponding to the bottom of the interstitial concrete, and foaming is performed. After cleaning the outer surface of the outer wall frame material, a waterproof sheet was adhered to the entire outer side surface.

The interior of the underground building thus constructed is completely shut out from the effects of groundwater and rainwater, so that the moisture-proof effect is dramatically improved, and the propagation of mold and germs is significantly reduced. This provides an underground space with excellent sanitary conditions.

[0036] Accordingly, the temperature can be set at a low cost by combining the excellent heat insulating effect, waterproofness, and moisture proofing effect of the present invention with good airtightness of the underground building. Agricultural storage warehouses where the temperature was set at 4 ° C to 15 ° C and the humidity was set at 60% to 70% could be built without using mechanical equipment.

Further, by setting the room temperature to 0 ° C. to −1 ° C., the airtightness of the underground building can be demonstrated as a food aging storage warehouse or ice temperature warehouse for aging meat, wine, and the like. The carbon dioxide storage warehouse can be built as a storage warehouse for fruits such as apples and oranges.

[0038] As described above, technologies that can be used in a wide variety of ways can significantly reduce running costs due to good heat retention, waterproofness, moisture proofness, and airtightness, and therefore can provide fresh food regardless of time. In addition, it can contribute to cost reduction of distribution products.
