Description

本発明は、基礎構造の施工方法に関する。   The present invention relates to a construction method for a foundation structure.

建物の基礎構造としては断熱材を敷設した構造が知られている。断熱材は居住部分の床下以外、例えば玄関などの土間部分にも敷設されることもある（例えば特許文献１参照）。
図１０は、従来の建物の基礎構造の概略構成を示す断面図である。図１０に示すように、基礎構造１００には、基礎１０１間に対して下から順に防湿用コンクリート１０２、断熱材１０３、土間コンクリート１０４が敷設されている。また、土間コンクリート１０４と基礎１０１との間には土間コンクリート１０４を囲むように断熱材１０５が配置されている。
ここで、基礎１０１と防湿用コンクリート１０２との間に隙間があると蟻が床下内に侵入してしまうので、防蟻用のシール剤でその隙間を埋める防蟻処理が施されている。 As a basic structure of a building, a structure in which a heat insulating material is laid is known. The heat insulating material may be laid on a soil portion such as an entrance other than under the floor of the living portion (see, for example, Patent Document 1).
FIG. 10 is a cross-sectional view showing a schematic configuration of a conventional building foundation structure. As shown in FIG. 10, moisture-proof concrete 102, heat insulating material 103, and soil concrete 104 are laid on the foundation structure 100 in order from the bottom with respect to the foundation 101. Further, a heat insulating material 105 is disposed between the soil concrete 104 and the foundation 101 so as to surround the soil concrete 104.
Here, if there is a gap between the foundation 101 and the moisture-proof concrete 102, ants will enter the floor, and therefore, an ant-proofing process is performed in which the gap is filled with a ant-proof sealant.

特開２００３−１９３５８２号公報JP 2003-193582 A

ところで、防蟻品質の確実性を高めるためには、防蟻処理を防湿用コンクリート１０２の硬化後に行うことが望まれている。このため、防湿用コンクリート１０２を硬化させてから防蟻処理を施し、防湿用コンクリート１０２上に断熱材１０３を敷設した後に土間コンクリート１０４を打設することになる。このため、防湿用コンクリート１０２と土間コンクリート１０４とがそれぞれ硬化する時間が必要となり、作業時間が長期化してしまうのが実状であった。
このため、本発明の課題は、防蟻処理を施す場合であっても作業時間の短縮化を図ることである。 By the way, in order to increase the certainty of the ant-proof quality, it is desired to perform the ant-proofing treatment after the moisture-proof concrete 102 is cured. For this reason, after the moisture-proof concrete 102 is hardened, an ant-proof treatment is performed, and after the heat insulating material 103 is laid on the moisture-proof concrete 102, the soil concrete 104 is placed. For this reason, the time required for the moisture-proof concrete 102 and the soil concrete 104 to be cured is required, and the working time is prolonged.
For this reason, the subject of this invention is aiming at shortening of working time, even when it is a case where an ant protection process is performed.

前記間隔Ｈに対して副断熱材７を設置する副断熱材設置工程と、
を含むことを特徴としている。 As shown in FIGS. 1 and 4, for example, the construction method of the foundation structure 1 according to the invention of claim 1
A first concrete placing step for placing the first concrete layer 3 so as to be in close contact with the side surface of the foundation 2;
A heat insulating material laying step of laying a heat insulating material 4 on the first concrete layer 3 before the first concrete layer 3 is cured so that a gap H is provided with respect to the side surface of the foundation 2;
Before the heat insulating material laying step or after the heat insulating material laying step, a mold installing step for installing the mold 10 for maintaining the distance H;
A second concrete placing step for placing the second concrete layer 5 in the mold 10 so as to overlap the heat insulating material 4;
A curing step of curing the first concrete layer 3 and the second concrete layer 5;
Removing the mold 10 and applying an ant sealant 6 to the boundary between the foundation 2 and the first concrete layer 3;
A sub-insulator installation step of installing the sub-insulator 7 with respect to the interval H;
It is characterized by including.

請求項１記載の発明によれば、基礎２と第一コンクリート層３との境界が前記間隔Ｈによって露出されているので、第一コンクリート層３及び第二コンクリート層５の硬化後に防蟻工程を施すことができる。
そして、第一コンクリート層３の硬化と第二コンクリート層５の硬化が同時に行われているために作業時間の短縮化を図ることができる。 According to invention of Claim 1, since the boundary of the foundation 2 and the 1st concrete layer 3 is exposed by the said space | interval H, after the 1st concrete layer 3 and the 2nd concrete layer 5 harden | cure, an ant-proof process is carried out. Can be applied.
And since hardening of the 1st concrete layer 3 and hardening of the 2nd concrete layer 5 are performed simultaneously, working time can be shortened.

請求項２記載の発明は、請求項１に記載の基礎構造１の施工方法において、例えば図１に示すように、
前記副断熱材７は、前記間隔Ｈよりも幅が小さい第一副断熱材７１と、第二副断熱材７２とを備え、
前記第一副断熱材７１は、断熱材４の端面に当接し、
前記第二副断熱材７２は、前記第一副断熱材７１の上に重ねられているとともに、前記基礎２の側面に当接していることを特徴としている。 Invention of Claim 2 is the construction method of the foundation structure 1 of Claim 1, for example, as shown in FIG.
The sub heat insulating material 7 includes a first sub heat insulating material 71 having a width smaller than the interval H, and a second sub heat insulating material 72,
Said 1st sub heat insulating material 71 contact | abuts to the end surface of the heat insulating material 4,
The second sub heat insulating material 72 is overlaid on the first sub heat insulating material 71 and is in contact with the side surface of the foundation 2.

断熱性の観点から考えると、副断熱材７が断熱材４の端面及び基礎２の側面に接して、基礎２の内側に連続した断熱材４，７のラインが形成されていることが好ましい。しかしながら副断熱材７が単体であると前記間隔Ｈ内に嵌合させなければ断熱材４の端面及び基礎２の側面の両者に当接させることは困難である。つまり、単体の副断熱材７に対してはある程度の精度が要求されることになる。
しかしながら、請求項２記載の発明のように、断熱材４の端面に当接する第一副断熱材７１と、第一副断熱材７１の上に重ねられているとともに基礎２の側面に当接する第二副断熱材７２とを副断熱材７が備えていると、断熱性を確保しつつも副断熱材７の形状の自由度を高めることができる。 From the viewpoint of heat insulation, it is preferable that the sub heat insulating material 7 is in contact with the end face of the heat insulating material 4 and the side surface of the foundation 2, and a continuous line of heat insulating materials 4 and 7 is formed inside the foundation 2. However, if the auxiliary heat insulating material 7 is a single body, it is difficult to contact both the end surface of the heat insulating material 4 and the side surface of the foundation 2 unless the sub heat insulating material 7 is fitted within the gap H. That is, a certain degree of accuracy is required for the single auxiliary heat insulating material 7.
However, as in the invention described in claim 2, the first sub heat insulating material 71 that contacts the end surface of the heat insulating material 4 and the first sub heat insulating material 71 that overlaps the first sub heat insulating material 71 and contacts the side surface of the foundation 2. When the secondary heat insulating material 7 includes the two secondary heat insulating materials 72, the degree of freedom of the shape of the sub heat insulating material 7 can be increased while ensuring the heat insulating property.

請求項３記載の発明は、請求項１記載の基礎構造１の施工方法において、例えば図９に示すように、
前記副断熱材７Ａが前記型枠として用いられることを特徴としている。 The invention according to claim 3 is the construction method of the foundation structure 1 according to claim 1, for example, as shown in FIG.
The sub heat insulating material 7A is used as the mold.

請求項３記載の発明によれば、副断熱材７Ａが型枠として用いられているので、型枠専用の部材が不要となり、施工時に用いられる部材を削減することができる。   According to the invention described in claim 3, since the auxiliary heat insulating material 7A is used as a mold, a member dedicated to the mold becomes unnecessary, and the number of members used at the time of construction can be reduced.

請求項４記載の発明は、請求項１〜３のいずれか一項に記載の基礎構造１の施工方法において、例えば図１に示すように、
前記第二コンクリート層５上にモルタル８を敷設するモルタル敷設工程をさらに含むことを特徴としている。 Invention of Claim 4 is the construction method of the foundation structure 1 as described in any one of Claims 1-3. For example, as shown in FIG.
The method further includes a mortar laying step of laying the mortar 8 on the second concrete layer 5.

請求項４記載の発明によれば、第二コンクリート層５上にモルタル８が敷設されるので、モルタル８を介してタイル９を設置することができ、見栄えをよくすることが可能である。   According to invention of Claim 4, since the mortar 8 is laid on the 2nd concrete layer 5, the tile 9 can be installed through the mortar 8, and it can improve appearance.

請求項５記載の発明は、請求項４記載の基礎構造１の施工方法において、例えば図１に示すように、
前記モルタル８は、前記第二コンクリート層５と前記副断熱材７との隙間Ｓ１を埋めていることを特徴としている。 Invention of Claim 5 is the construction method of the foundation structure 1 of Claim 4, for example, as shown in FIG.
The mortar 8 is characterized by filling a gap S1 between the second concrete layer 5 and the auxiliary heat insulating material 7.

請求項５記載の発明によれば、第二コンクリート層５と副断熱材７との隙間Ｓ１をモルタル８が埋めているので、副断熱材７の位置ズレを防止することができるとともに断熱性も高めることができる。   According to the invention described in claim 5, since the mortar 8 fills the gap S1 between the second concrete layer 5 and the auxiliary heat insulating material 7, it is possible to prevent the positional displacement of the auxiliary heat insulating material 7 and also the heat insulating property. Can be increased.

本発明によれば、防蟻処理を施す場合であっても作業時間の短縮化を図ることができる。   According to the present invention, the working time can be shortened even when the ant protection treatment is performed.

以下、図面を参照して本発明の実施の形態について説明する。図１は本実施形態に係る建物の基礎構造１を示す断面図である。図１に示すように、基礎構造１には、地中に埋設された基礎２と、基礎２の立ち上がり部２１の側面に対して密着するように地面に設けられた第一コンクリート層３とが設けられている。第一コンクリート層３は防湿土間コンクリートとして機能する。
また、第一コンクリート層３上には、基礎２の立ち上がり部２１の側面に対して間隔Ｈを空けるように、例えば防蟻断熱材などの断熱材４が敷設されている。断熱材４上には、当該断熱材４とともに間隔Ｈを形成するように第二コンクリート層５が重ねて配置されている。第二コンクリート層５は下地土間コンクリートとして機能する。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing a building foundation 1 according to this embodiment. As shown in FIG. 1, the foundation structure 1 includes a foundation 2 buried in the ground and a first concrete layer 3 provided on the ground so as to be in close contact with the side surface of the rising portion 21 of the foundation 2. Is provided. The first concrete layer 3 functions as moisture-proof soil concrete.
Further, on the first concrete layer 3, a heat insulating material 4 such as an ant-proof heat insulating material is laid so as to leave a space H with respect to the side surface of the rising portion 21 of the foundation 2. On the heat insulating material 4, the 2nd concrete layer 5 is piled up so that the space | interval H may be formed with the said heat insulating material 4. FIG. The second concrete layer 5 functions as the ground soil concrete.

間隔Ｈ内においては、立ち上がり部２１と第一コンクリート層３との境界に塗布された防蟻シール剤６と、例えば防蟻断熱材などの副断熱材７とが設けられている。
副断熱材７は、間隔Ｈよりも幅が小さい第一副断熱材７１と、第二副断熱材７２とを備えている。第一副断熱材７１は断熱材４の端面に当接している。第一副断熱材７１と基礎２の立ち上がり部２１との間には隙間Ｓ１が設けられていて、この隙間Ｓ１内に防蟻シール剤６が配置されている。
第二副断熱材７２は、第一副断熱材７１の上に重ねられているとともに立ち上がり部２１の側面に当接している。このため、第一副断熱材７１と第二コンクリート層５との間には隙間Ｓ２が形成されることになる。また、第二副断熱材７２の上面と立ち上がり部２１の上面とは面一となっている。 Within the interval H, an ant-proof sealant 6 applied to the boundary between the rising portion 21 and the first concrete layer 3 and a secondary heat-insulating material 7 such as an ant-proof heat-insulating material are provided.
The sub heat insulating material 7 includes a first sub heat insulating material 71 having a width smaller than the interval H and a second sub heat insulating material 72. The first sub heat insulating material 71 is in contact with the end face of the heat insulating material 4. A gap S <b> 1 is provided between the first sub heat insulating material 71 and the rising portion 21 of the foundation 2, and the ant sealant 6 is disposed in the gap S <b> 1.
The second sub heat insulating material 72 is overlaid on the first sub heat insulating material 71 and is in contact with the side surface of the rising portion 21. For this reason, a gap S <b> 2 is formed between the first sub heat insulating material 71 and the second concrete layer 5. Further, the upper surface of the second sub heat insulating material 72 and the upper surface of the rising portion 21 are flush with each other.

そして、隙間Ｓ２を埋めるように第二コンクリート層５の上面及び第二副断熱材７２の側面には例えばバサモルタルなどのモルタル８が重ねられている。このモルタル８に対してはタイル９が貼付されている。   Then, a mortar 8 such as a bath mortar is overlaid on the upper surface of the second concrete layer 5 and the side surface of the second auxiliary heat insulating material 72 so as to fill the gap S2. A tile 9 is attached to the mortar 8.

次に、基礎構造１の施工方法について説明する。図２〜図８は基礎構造１の施工方法の各工程を示す断面図である。
まず、基礎２の設置後においては、図２に示すように、基礎２の立ち上がり部２１の側面に対して密着するように第一コンクリート層３を打設する（第一コンクリート打設工程）。 Next, the construction method of the foundation structure 1 will be described. 2-8 is sectional drawing which shows each process of the construction method of the foundation structure 1. FIG.
First, after the foundation 2 is installed, as shown in FIG. 2, the first concrete layer 3 is placed so as to be in close contact with the side surface of the rising portion 21 of the foundation 2 (first concrete placing step).

その後、図３に示すように、基礎２の立ち上がり部２１の側面に対して間隔Ｈが空くように、第一コンクリート層３の硬化前、つまり湿潤状態である場合に当該第一コンクリート層３上に断熱材４を敷設する（断熱材敷設工程）。
そして、図４に示すように、断熱材敷設工程の後に間隔Ｈを保持するための型枠１０を設置する（型枠設置工程）。型枠１０には、コンクリートと直接接する堰板１１と、当該堰板１１を所定の位置に固定する支保工１２とが設けられている。堰板１１が断熱材４の端面に当接した状態で垂直となるように支保工１２で堰板１１の位置を固定する。なお、図示はしていないが、第二コンクリート層５を打設する領域が型枠１０により囲まれている。 Thereafter, as shown in FIG. 3, the first concrete layer 3 is not hardened before the first concrete layer 3, that is, in a wet state, so that a gap H is provided with respect to the side surface of the rising portion 21 of the foundation 2. The heat insulating material 4 is laid in (heat insulating material laying step).
And as shown in FIG. 4, the mold 10 for hold | maintaining the space | interval H is installed after a heat insulating material laying process (formwork installation process). The mold 10 is provided with a dam plate 11 that is in direct contact with the concrete, and a support 12 that fixes the dam plate 11 at a predetermined position. The position of the weir plate 11 is fixed by the support work 12 so that the weir plate 11 is vertical in a state where it is in contact with the end face of the heat insulating material 4. Although not shown, the area where the second concrete layer 5 is placed is surrounded by the mold 10.

次いで、図５に示すように、断熱材４上に重なるように型枠１０内に第二コンクリート層５を打設する（第二コンクリート打設工程）。
このままの状態で所定時間待機して、第一コンクリート層３及び第二コンクリート層５を同時に硬化させる（硬化工程）。 Next, as shown in FIG. 5, the second concrete layer 5 is placed in the mold 10 so as to overlap the heat insulating material 4 (second concrete placing step).
In this state, the first concrete layer 3 and the second concrete layer 5 are cured simultaneously for a predetermined time (curing step).

硬化後においては、図６に示すように、型枠１０を取り外して、基礎２の立ち上がり部２１と第一コンクリート層３との境界に防蟻シール剤６を塗布する（防蟻工程）。境界に隙間がある場合はその隙間を埋めるように防蟻シール剤６を塗布する。
そして、図７に示すように、間隔Ｈに対して副断熱材７を設置する（副断熱材設置工程）。このとき、断熱材４の端面に当接するように第一副断熱材７１を第一コンクリート層３上に載置し、隙間Ｓ１を形成する。次いで、第一副断熱材７１の上に第二副断熱材７２を重ねて、基礎２の立ち上がり部２１の側面に当接させる。 After the curing, as shown in FIG. 6, the mold 10 is removed, and the ant sealant 6 is applied to the boundary between the rising portion 21 of the foundation 2 and the first concrete layer 3 (ant proofing process). If there is a gap at the boundary, the ant sealant 6 is applied so as to fill the gap.
Then, as shown in FIG. 7, the auxiliary heat insulating material 7 is installed with respect to the interval H (sub heat insulating material installing step). At this time, the 1st sub heat insulating material 71 is mounted on the 1st concrete layer 3 so that it may contact | abut to the end surface of the heat insulating material 4, and the clearance gap S1 is formed. Next, the second sub heat insulating material 72 is stacked on the first sub heat insulating material 71 and brought into contact with the side surface of the rising portion 21 of the foundation 2.

副断熱材７の設置が完了すると、図８に示すように、第二コンクリート層５上にモルタル８を敷設する（モルタル敷設工程）。このとき、第二コンクリート層５と第二副断熱材７２との隙間Ｓ２をモルタル８で埋めるとともに、第二副断熱材７２の側面もモルタル８で覆う。
そして、モルタル８上にタイル９を貼付することで、図１に示した基礎構造１が形成される。 When the installation of the auxiliary heat insulating material 7 is completed, the mortar 8 is laid on the second concrete layer 5 as shown in FIG. 8 (mortar laying step). At this time, the gap S <b> 2 between the second concrete layer 5 and the second secondary heat insulating material 72 is filled with the mortar 8, and the side surface of the second secondary heat insulating material 72 is also covered with the mortar 8.
And the basic structure 1 shown in FIG. 1 is formed by sticking the tile 9 on the mortar 8.

以上のように、基礎２と第一コンクリート層３との境界が間隔Ｈによって露出されているので、第一コンクリート層３及び第二コンクリート層５の硬化後に防蟻工程を施すことができる。
そして、第一コンクリート層３の硬化と第二コンクリート層５の硬化が同時に行われているために作業時間の短縮化を図ることができる。 As described above, since the boundary between the foundation 2 and the first concrete layer 3 is exposed by the interval H, an ant-proofing step can be performed after the first concrete layer 3 and the second concrete layer 5 are cured.
And since hardening of the 1st concrete layer 3 and hardening of the 2nd concrete layer 5 are performed simultaneously, working time can be shortened.

また、断熱材４の端面に当接する第一副断熱材７１と、第一副断熱材７１の上に重ねられているとともに基礎２の立ち上がり部２１の側面に当接する第二副断熱材７２とを副断熱材７が備えているので、断熱性を確保しつつも副断熱材７の形状の自由度を高めることができる。   Moreover, the 1st sub heat insulating material 71 contact | abutted to the end surface of the heat insulating material 4, and the 2nd sub heat insulating material 72 contact | abutted on the side surface of the rising part 21 of the foundation 2 while being piled up on the 1st sub heat insulating material 71, Since the auxiliary heat insulating material 7 is provided, the degree of freedom of the shape of the auxiliary heat insulating material 7 can be increased while ensuring the heat insulating property.

また、第二コンクリート層５上にモルタル８が敷設されるので、モルタル８を介してタイル９を設置することができ、見栄えをよくすることが可能である。これに加えて防汚性、防水性、保温性等の効果を持つ種々のタイルを選択して適用すれば住環境の一層の向上が可能となる。
また、第二コンクリート層５と副断熱材７との隙間Ｓ２をモルタル８が埋めているので、副断熱材７の位置ズレを防止することができるとともに断熱性も高めることができる。 Moreover, since the mortar 8 is laid on the second concrete layer 5, the tile 9 can be installed through the mortar 8, and the appearance can be improved. In addition to this, it is possible to further improve the living environment by selecting and applying various tiles having effects such as antifouling properties, waterproof properties, and heat retaining properties.
In addition, since the mortar 8 fills the gap S2 between the second concrete layer 5 and the auxiliary heat insulating material 7, it is possible to prevent the positional displacement of the auxiliary heat insulating material 7 and to improve the heat insulating property.

なお、本発明は上記実施形態に限らず適宜変更可能である。以下、変形例について説明するが、上記実施形態と同一の部分においては同一の符号を付しその説明を省略する。   Note that the present invention is not limited to the above embodiment, and can be modified as appropriate. Hereinafter, although a modification is demonstrated, the same code | symbol is attached | subjected in the part same as the said embodiment, and the description is abbreviate | omitted.

例えば、上記実施形態においては、型枠設置工程が断熱材敷設工程の後に行った場合を例示して説明したが、型枠設置工程は断熱材敷設工程の前に行うことも可能である。
また、上記実施形態では、堰板１１と支保工１２とを備える型枠１０を用いた型枠設置工程を例示して説明したが、例えば図９に示すように、型枠１０の代わりに副断熱材７Ａを用いることも可能である。この場合、第一コンクリート層３及び第二コンクリート層５が硬化した後に副断熱材７Ａを一時的に取り外して、基礎２と第一コンクリート層３との境界を露出させてから当該境界に防蟻シール剤６を塗布する。その後、再度副断熱材７Ａを間隔Ｈ内に配置する。
このように、副断熱材７Ａが型枠として用いられていれば、型枠専用の部材が不要となり、施工時に用いられる部材を削減することができる。 For example, in the above-described embodiment, the case where the mold installation process is performed after the heat insulating material laying process has been described as an example. However, the mold frame installation process can be performed before the heat insulating material laying process.
Moreover, in the said embodiment, although the mold installation process using the mold 10 provided with the dam plate 11 and the support work 12 was illustrated and demonstrated, for example, as shown in FIG. It is also possible to use the heat insulating material 7A. In this case, after the first concrete layer 3 and the second concrete layer 5 are hardened, the auxiliary heat insulating material 7A is temporarily removed to expose the boundary between the foundation 2 and the first concrete layer 3, and then the ant-preventive material is applied to the boundary. A sealant 6 is applied. Thereafter, the auxiliary heat insulating material 7 </ b> A is disposed within the interval H again.
In this way, if the auxiliary heat insulating material 7A is used as a mold, a member dedicated to the mold becomes unnecessary, and the number of members used during construction can be reduced.
