Description

本発明は、沓摺用充填材、沓摺部、及び沓摺部の製造方法に関する。   The present invention relates to a hulling filler, a hulling portion, and a method for manufacturing a hulling portion.

従来、建屋の床に設けられる沓摺部は、下面に凹部を有する金属製の沓摺と、その凹部内に充填されたモルタルとから成る(特許文献1参照)。   Conventionally, a hull portion provided on a floor of a building is composed of a metal hull with a recess on the lower surface and a mortar filled in the recess (see Patent Document 1).

特開平11−256934号公報Japanese Patent Laid-Open No. 11-256934

従来の沓摺部は、沓摺の凹部にモルタルを流し込み、それを硬化させる方法で製造される。モルタルの硬化時間は長いため、従来の沓摺部は製造に長時間を要する。また、従来の沓摺部は、衝撃を与えたとき、モルタルが割れ易かった。また、モルタルは沓摺の凹部から脱落し易く、脱落を防止するために、沓摺の凹部に鉄筋棒を設ける必要があった。   The conventional hulling part is manufactured by a method of pouring mortar into the concave part of the hulling and curing it. Since the curing time of mortar is long, the conventional hulling portion takes a long time to manufacture. Further, in the conventional hulling part, the mortar was easily cracked when an impact was applied. In addition, the mortar is easy to drop out from the recess of the huller and it is necessary to provide a reinforcing bar in the huller's recess to prevent the hull from falling off.

本発明は、こうした問題にかんがみてなされたものであり、上記の課題を解決できる沓摺用充填材、沓摺部、及び沓摺部の製造方法を提供することを目的としている。   The present invention has been made in view of these problems, and an object thereof is to provide a hulling filler, a hulling portion, and a method of manufacturing a hulling portion that can solve the above-described problems.

The hulling filler and the hulling portion manufactured using the hulling filler are excellent in impact resistance. Moreover, if this filling material for a hulling is used, the manufacturing efficiency of a hulling part can be improved. Moreover, if this hulling filler is used, the possibility that the hulling filler falls off from the recesses of the hulling can be reduced.

本開示の一態様は、下面に凹部を有する沓摺と、前記凹部に充填された、上記の沓摺用充填材と、を備える沓摺部である。この沓摺部は、耐衝撃性に優れる。また、この沓摺部は、高い製造効率で製造することができる。また、この沓摺部は、沓摺の凹部から沓摺用充填材が脱落するおそれを低減できる。   One aspect of the present disclosure is a hull portion including a hull having a recess on a lower surface and the hull filling material filled in the recess. This hull portion is excellent in impact resistance. Moreover, this hulling part can be manufactured with high manufacturing efficiency. Moreover, this hulling part can reduce a possibility that the filler for hulling may fall out from the recessed part of a hulling.

本開示の一態様は、下面に凹部を有する沓摺と、前記凹部に充填された沓摺用充填材と、を備える沓摺部の製造方法であって、少なくとも石こう及び水を含む流動体を前記凹部に充填し、硬化させて前記沓摺用充填材を形成する沓摺部の製造方法である。この沓摺部の製造方法によれば、耐衝撃性に優れる沓摺を製造できる。また、この製造方法によれば、沓摺部の製造効率を向上させることができる。また、この製造方法によれば、沓摺の凹部から沓摺用充填材が脱落するおそれを低減できる。   One aspect of the present disclosure is a method for manufacturing a hull portion including a hull having a recess on a lower surface and a hulling filler filled in the recess, wherein the fluid includes at least gypsum and water. It is the manufacturing method of the hulling part which fills the said recessed part and makes it harden | cure and forms the said filler for hulling. According to this method for manufacturing a hull portion, a hull with excellent impact resistance can be manufactured.

本開示の実施形態を説明する。
1.沓摺用充填材
本開示の沓摺用充填材は、少なくとも石こうを含む。本開示の沓摺用充填材は、少なくとも石こうを含むことにより、以下の効果を奏する。すなわち、本開示の沓摺用充填材は耐衝撃性が高い。また、本開示の沓摺用充填材は軽量である。また、本開示の沓摺用充填材は、沓摺との密着性が高い。その結果、沓摺用充填材が沓摺から脱落し難くなる。また、本開示の沓摺用充填材は、沓摺の凹部全体に充填することが容易である。また、本開示の沓摺用充填材は、例えば、沓摺の凹部からはみ出したとき、そのはみ出した部分を削り取ることが容易である。
An embodiment of the present disclosure will be described.
1. The hulling filler of this indication contains at least gypsum. By including at least gypsum, the hulling filler of the present disclosure has the following effects. That is, the hulling filler according to the present disclosure has high impact resistance. Further, the hulling filler of the present disclosure is lightweight. Further, the hulling filler of the present disclosure has high adhesion to the hulling. As a result, it becomes difficult for the filler for hulling to fall out of the hull. Moreover, the filling material for hulling of this indication is easy to fill the whole recessed part of a hulling. In addition, for example, when the filling material for hulling of the present disclosure protrudes from the concave portion of the hulling, it is easy to scrape off the protruding portion.

100質量部の沓摺用充填材に含まれる石こうの量は、固形分換算で、70質量部以上であることが好ましい。この範囲内である場合、上記の効果が一層顕著になる。
本開示の沓摺用充填材は、例えば、少なくとも石こう及び水を含む流動体を沓摺の凹部に充填し、その流動体を硬化させて製造することができる。流動体が石こうを含むことにより、以下の効果を奏する。すなわち、流動体の硬化時間が短くなるため、沓摺部の製造効率を向上させることができる。また、流動体が硬化するときに膨張し易くなるので、形成された沓摺用充填材と沓摺との密着性が高くなる。その結果、沓摺用充填材が沓摺から脱落し難くなる。また、流動体を沓摺の凹部全体に充填し、凹部全体において沓摺用充填材を形成することが容易になる。
The amount of gypsum contained in 100 parts by weight of the filler for pallet is preferably 70 parts by weight or more in terms of solid content. When it is within this range, the above effect becomes more remarkable.
The hulling filler according to the present disclosure can be manufactured, for example, by filling a fluid containing at least gypsum and water into the concave portion of the hulling and curing the fluid. When the fluid contains gypsum, the following effects can be obtained. That is, since the hardening time of the fluid is shortened, the manufacturing efficiency of the hulling portion can be improved. Moreover, since it becomes easy to expand | swell when a fluid hardens | cures, the adhesiveness of the formed filler for hulling and a hulling becomes high. As a result, it becomes difficult for the filler for hulling to fall out of the hull. In addition, it becomes easy to fill the fluid into the entire recess of the hull and form the hulling filler in the entire recess.

石こうとしては、例えば、二水石こう、半水石こう、無水石こう等が挙げられる。特に半水石こうを用いることが好ましい。半水石こうを用いると、流動体の硬化時間が一層短くなる。半水石こうには、α型半水石こうと、β型半水石こうとがある。α型半水石こうを用いると、流動体の硬化時間がさらに短くなる。   Examples of the gypsum include dihydrate gypsum, hemihydrate gypsum, and anhydrous gypsum. It is particularly preferable to use hemihydrate gypsum. When hemihydrate gypsum is used, the hardening time of the fluid is further shortened. There are two types of half-water gypsum: α-type and half-type gypsum. When α-type hemihydrate gypsum is used, the curing time of the fluid is further shortened.

本開示の沓摺用充填材は、バーミキュライト又は焼成バーミキュライトをさらに含むことができる。バーミキュライトとは、酸化ケイ素、酸化マグネシウム、酸化アルミニウムを主成分とする鉱物であり、ひる石とも呼ばれる。バーミキュライトは、高温で急熱すると膨張する性質を持つ。焼成バーミキュライトとは、バーミキュライト原石を高温(800〜1000℃)の焼成炉の中を通過させて膨張させたものである。   The hulling filler of the present disclosure may further include vermiculite or fired vermiculite. Vermiculite is a mineral mainly composed of silicon oxide, magnesium oxide, and aluminum oxide, and is also called vermiculite. Vermiculite has the property of expanding when rapidly heated at high temperatures. The calcined vermiculite is obtained by expanding a raw vermiculite through a high-temperature (800 to 1000 ° C.) firing furnace.

本開示の沓摺用充填材がバーミキュライト又は焼成バーミキュライトをさらに含む場合、沓摺用充填材の耐衝撃性が一層向上する。また、沓摺用充填材が一層軽量になる。また、沓摺用充填材にネジを埋め込む際の作業性が一層向上する。   When the hulling filler of the present disclosure further includes vermiculite or fired vermiculite, the impact resistance of the hulling filler is further improved. Moreover, the filler for hulling becomes lighter. Moreover, the workability | operativity at the time of embedding a screw | thread in the filler for hulling improves further.

本開示の沓摺用充填材におけるバーミキュライト又は焼成バーミュライトの配合量は、石こう100質量部に対し、3〜5質量部の範囲が好ましい。この範囲内である場合、セルフレベリング性及びネジ埋め込み性において優れる。   The blending amount of vermiculite or calcined vermulite in the hulling filler of the present disclosure is preferably in the range of 3 to 5 parts by mass with respect to 100 parts by mass of gypsum. When it is within this range, it is excellent in self-leveling property and screw embedding property.

本開示の沓摺用充填材は、その他に、適宜公知の成分を含んでいてもよい。
2.沓摺部
沓摺部は、下面に凹部を有する沓摺と、前記凹部に充填された沓摺用充填材とを備える。図1、図2に示すように、沓摺1は、例えば、下面が開放された中空の長尺部材である。その長尺部材は、例えば、中空の角筒状部材において、下方が開放された形状(いわゆるコノ字形状)を有する。
The hulling filler of the present disclosure may contain other known components as appropriate.
2. The hull portion The hull portion includes a hull having a recess on the lower surface, and a hull filling material filled in the recess. As shown in FIGS. 1 and 2, the huller 1 is, for example, a hollow long member whose lower surface is opened. The elongate member has, for example, a hollow rectangular tube-like member with a shape in which the lower part is opened (so-called cono-shape).

沓摺1は、その下面が開放されることにより、下面に凹部3を有する。沓摺1を使用するとき、その端面は、図1に示すように、たて枠5に接続される。沓摺1は、図3、図4に示すように、上面が段差を有する形態であってもよい。   The huller 1 has a recess 3 on its lower surface by opening its lower surface. When the huller 1 is used, its end face is connected to a vertical frame 5 as shown in FIG. As shown in FIGS. 3 and 4, the huller 1 may have a form in which the upper surface has a step.

沓摺1の材質は特に限定されず、例えば、金属、樹脂等とすることができる。金属としては、例えば、ステンレス、鋼、アルミ等が挙げられる。樹脂としては、例えば、硬質塩化ビニール等が挙げられる。   The material of the huller 1 is not specifically limited, For example, it can be set as a metal, resin, etc. Examples of the metal include stainless steel, steel, and aluminum. Examples of the resin include hard vinyl chloride.

図5、図6に示すように、沓摺部7を構成する沓摺用充填材9は、沓摺1の凹部3に充填されている。沓摺用充填材9は前記「1.沓摺用充填材」の項で述べたものである。沓摺用充填材9は、凹部3の全てに充填してもよいし、一部に充填してもよい。また、沓摺用充填材9の一部は、凹部3の外側に存在してもよい。沓摺用充填材9は、その内部に鉄筋棒等の他の部材を含んでいてもよい。   As shown in FIGS. 5 and 6, the hulling filler 9 constituting the hulling portion 7 is filled in the concave portion 3 of the hulling 1. The hulling filler 9 is the same as that described in the section “1. hulling filler”. The hulling filler 9 may be filled in all of the recesses 3 or a part thereof. Further, a part of the hulling filler 9 may exist outside the recess 3. The hulling filler 9 may include other members such as a reinforcing bar inside.

本開示の沓摺部では、沓摺と沓摺用充填材との密着性が高い。その結果、沓摺用充填材が沓摺から脱落し難くなる。また、本開示の沓摺部を構成する沓摺用充填材は、耐衝撃性が高い。   In the hulling portion of the present disclosure, the adhesion between the hulling and the hulling filler is high. As a result, it becomes difficult for the filler for hulling to fall out of the hull. Moreover, the hulling filler constituting the hulling part of the present disclosure has high impact resistance.

本開示の沓摺部は、例えば、少なくとも石こう及び水を含む流動体を沓摺の凹部に充填し、その流動体を硬化させて沓摺用充填材を形成し、製造することができる。流動体が石こうを含むことにより、流動体の硬化時間が短くなる。その結果、沓摺部の製造効率を向上させることができる。   The hulling portion of the present disclosure can be manufactured, for example, by filling a fluid containing at least gypsum and water into the concave portion of the hulling and curing the fluid to form a hulling filler. When the fluid contains gypsum, the curing time of the fluid is shortened. As a result, the manufacturing efficiency of the hulling portion can be improved.

本開示の沓摺部を構成する沓摺用充填材がバーミキュライト又は焼成バーミキュライトをさらに含む場合、沓摺用充填材の耐衝撃性が一層向上する。また、沓摺用充填材が一層軽量になる。また、沓摺用充填材にネジを埋め込む際の作業性が一層向上する。   When the hulling filler constituting the hulling portion of the present disclosure further includes vermiculite or fired vermiculite, the impact resistance of the hulling filler is further improved. Moreover, the filler for hulling becomes lighter. Moreover, the workability | operativity at the time of embedding a screw | thread in the filler for hulling improves further.

3.沓摺部の製造方法
本開示の沓摺部の製造方法では、少なくとも石こう及び水を含む流動体を沓摺の凹部に充填し、硬化させて沓摺用充填材を形成する。本開示の沓摺部の製造方法で形成される沓摺用充填材は、前記「1.沓摺用充填材」の項で述べたものである。また、本開示の沓摺部の製造方法で使用する流動体は、前記「1.沓摺用充填材」の項で述べたものである。
3. The manufacturing method of the hulling part In the manufacturing method of the hulling part of this indication, the fluid containing at least gypsum and water is filled into the concave part of the hulling, and is hardened to form the hulling filling material. The hulling filler formed by the method for manufacturing a hulling portion of the present disclosure is the same as that described in the section “1. In addition, the fluid used in the method for manufacturing a hull portion according to the present disclosure is the same as that described in the section “1. Filler for hulling”.

本開示の沓摺部の製造方法では、石こう及び水を含む流動体を用いるので、以下の効果を奏する。すなわち、流動体の硬化時間が短くなる。その結果、沓摺部の製造効率を向上させることができる。また、流動体が硬化するときに膨張し易くなるので、形成された沓摺用充填材と沓摺との密着性が高くなる。その結果、沓摺用充填材が沓摺から脱落し難くなる。   In the manufacturing method of the hulling part of this indication, since the fluid containing gypsum and water is used, the following effects are produced. That is, the curing time of the fluid is shortened. As a result, the manufacturing efficiency of the hulling portion can be improved. Moreover, since it becomes easy to expand | swell when a fluid hardens | cures, the adhesiveness of the formed filler for hulling and a hulling becomes high. As a result, it becomes difficult for the filler for hulling to fall out of the hull.

また、形成された沓摺用充填材と沓摺との密着性が高いため、従来の沓摺部のように、沓摺に鉄筋棒を溶接することが必須ではない。なお、従来の沓摺では、モルタルから成る沓摺用充填材が沓摺から脱落することを防止するため、沓摺に鉄筋棒を溶接することが必要であった。   Further, since the adhesion between the formed hulling filler and the hulling is high, it is not essential to weld a reinforcing bar to the hulling like a conventional hulling portion. In the conventional hulling, it was necessary to weld a reinforcing bar to the hulling to prevent the hulling filler made of mortar from falling off the hulling.

また、流動体を沓摺の凹部全体に充填し、凹部全体において沓摺用充填材を形成することが容易になる。また、例えば、形成された沓摺用充填材が沓摺の凹部からはみ出したとき、そのはみ出した部分を削り取ることが容易である。   In addition, it becomes easy to fill the fluid into the entire recess of the hull and form the hulling filler in the entire recess. For example, when the formed hulling filler protrudes from the recess of the hulling, it is easy to scrape off the protruding portion.

本開示の製造方法で用いる流動体は、例えば、バーミキュライト又は焼成バーミキュライトをさらに含むことができる。流動体がバーミキュライト又は焼成バーミキュライトをさらに含む場合、形成された沓摺用充填材の耐衝撃性が一層向上する。また、形成された沓摺用充填材が一層軽量になる。また、形成された沓摺用充填材にネジを埋め込む際の作業性が一層向上する。   The fluid used in the production method of the present disclosure can further include, for example, vermiculite or calcined vermiculite. When the fluid further contains vermiculite or fired vermiculite, the impact resistance of the formed hulling filler is further improved. Further, the formed hulling filler becomes lighter. Moreover, the workability | operativity at the time of embedding a screw in the formed filler for hulling improves further.

4.沓摺部の使用方法
本開示の沓摺部7は、例えば、工場で製造することができる。その場合の製造方法は以下のとおりである。まず、沓摺1と、帯アンカー11と、一対のたて枠5及び上枠15を溶接して構成した3方枠と、を用意する。次に、帯アンカー11を沓摺1に溶接する。次に、流動体を沓摺1の凹部3に流し込み、硬化させて、沓摺部7とする。次に、沓摺部7と3方枠とを溶接し、四方枠14を作成する。作成した四方枠14を工場から出荷し、現場に搬入する。なお、後述する鉄筋棒13は、工場では沓摺部7に固定せず、現場で床スラブに設置する。
4). How to use the hull portion The hull portion 7 of the present disclosure can be manufactured in a factory, for example. The manufacturing method in that case is as follows. First, the huller 1, the band anchor 11, and a three-way frame formed by welding a pair of the vertical frame 5 and the upper frame 15 are prepared. Next, the band anchor 11 is welded to the hull 1. Next, the fluid is poured into the recess 3 of the huller 1 and cured to form a huller 7. Next, the hull portion 7 and the three-side frame are welded to create a four-side frame 14. The created four-sided frame 14 is shipped from the factory and carried to the site. In addition, the reinforcing bar 13 mentioned later is not fixed to the hulling part 7 in a factory, but is installed in a floor slab on the spot.

また、本開示の沓摺部7を現場で製造し、使用してもよい。その場合は、以下のように沓摺部7を現場で製造し、使用することができる。まず、沓摺1と、一対のたて枠5と、上枠15とを現場に搬入する。搬入される沓摺1には、予め工場において帯アンカー11が溶接されている。次に、流動体を沓摺1の凹部3に流し込み、硬化させて、沓摺部7とする。次に、沓摺部7と、一対のたて枠5と、上枠15と、をビス又は溶接で固定し、四方枠14を作成する。   Moreover, you may manufacture and use the hulling part 7 of this indication on-site. In that case, the hulling part 7 can be manufactured and used on site as follows. First, the huller 1, the pair of vertical frames 5, and the upper frame 15 are carried into the site. A belt anchor 11 is welded to the pallet 1 to be carried in advance at the factory. Next, the fluid is poured into the recess 3 of the huller 1 and cured to form a huller 7. Next, the hull portion 7, the pair of vertical frames 5, and the upper frame 15 are fixed with screws or welding to create a four-sided frame 14.

沓摺部7を含む四方枠14は、以下のようにして、建物の躯体に対し固定することができる。具体的には、図6に示すように、床スラブ17に鉄筋棒13を設置し、その鉄筋棒13と帯アンカー11とを溶接することで、沓摺部7を、床スラブ17に固定する。また、図5に示すように、たて枠5を、帯アンカー19及び鉄筋棒21を用いて鉄骨23に固定する。上枠15も、図示しない躯体に固定する。なお、躯体が木造の場合は、ビス留めにより四方枠14を躯体に固定してもよい。   The four-sided frame 14 including the hull portion 7 can be fixed to the building frame as follows. Specifically, as shown in FIG. 6, the reinforcing bar 13 is installed on the floor slab 17 and the reinforcing bar 13 and the band anchor 11 are welded to fix the hull portion 7 to the floor slab 17. . Further, as shown in FIG. 5, the vertical frame 5 is fixed to the steel frame 23 using the band anchor 19 and the reinforcing bar 21. The upper frame 15 is also fixed to a housing (not shown). In addition, when the housing is wooden, the four-sided frame 14 may be fixed to the housing by screwing.

次に、図5、図6に示すように、沓摺部7の両側にコンクリートの塗り床25を設ける。コンクリートの塗り床25の高さは、沓摺部7の上面よりわずかに低い高さとする。

(2)試験方法
流動体S1〜S7のそれぞれについて、以下の方法で試験を行った。また、石こうボードについても同様の試験を行った。この石こうボードは、JIS A6901(GB−R)である。
(2) Test method About each of fluid S1-S7, it tested by the following methods. A similar test was performed on gypsum board. This gypsum board is JIS A6901 (GB-R).

(2−1)比重
容積210ccの容器に流動体を摺り切り一杯に充填した。よって、充填時における流動体の容積は210ccである。その後、室温で24時間静置した。流動体は硬化し、沓摺用充填材が形成された。沓摺用充填材の質量を測定し、容積(210cc)で除することにより、沓摺用充填材の比重を算出した。石こうボードについても、周知の方法で比重を算出した。
(2-1) Specific gravity The fluid was scraped into a container with a volume of 210 cc and filled to a full extent. Therefore, the volume of the fluid at the time of filling is 210 cc. Then, it left still at room temperature for 24 hours. The fluid was cured, and a filigree filler was formed. The specific gravity of the hulling filler was calculated by measuring the mass of the hulling filler and dividing by the volume (210 cc). The specific gravity of the gypsum board was also calculated by a well-known method.

(2−2)硬化時間
容積300ccのビーカーに、200ccの流動体を充填し、試験体とした。充填直後に、試験体を横に90°傾けた。流動体を充填した時点から、流動性が無くなる時点までの時間を硬化開始時間とした。硬化開始時間の経過後、5分ごとに、直径5mmの木棒を流動体に対し垂直に突き刺す操作を行った。流動体を充填した時点から、木棒が刺さらなくなる時点までの時間を硬化終了時間とした。
(2-2) Curing time A 200 cc fluid was filled into a 300 cc beaker to prepare a test specimen. Immediately after filling, the specimen was tilted 90 ° to the side. The time from when the fluid was filled to when the fluidity disappeared was defined as the curing start time. Every 5 minutes after the lapse of the curing start time, an operation of piercing a wooden bar having a diameter of 5 mm perpendicularly to the fluid was performed.

次に、試験体を1.5mの高さから落下させた。沓摺用充填材に変化がなかった場合は○と評価し、沓摺用充填材にひび割れが生じた場合は×と評価した。石こうボードについても、上と同様に評価を行った。   Next, the test body was dropped from a height of 1.5 m. When there was no change in the hulling filler, it was evaluated as “good”, and when cracking occurred in the hulling filler, it was evaluated as “poor”. The gypsum board was also evaluated in the same manner as above.

(2−10)圧縮強度
前記「(2−6)ネジ埋込み性」と同様に、沓摺用充填材を形成した。容器から取り出した沓摺用充填材を試験体とした。試験体に対し、144kN/分の試験荷重を加え、試験体が降伏し始めるまでの時間(以下では降伏時間とする)を計測した。降伏時間の長さに基づき、試験体の圧縮強度を評価した。
(2-10) Compressive strength As in the case of “(2-6) Screw embedding property”, a filler for hulling was formed. The hulling filler taken out from the container was used as a test specimen. A test load of 144 kN / min was applied to the test body, and the time until the test body started to yield (hereinafter referred to as the yield time) was measured. Based on the length of the yield time, the compressive strength of the specimen was evaluated.

×: Yield time is less than 30 seconds ○: Yield time is 30 seconds or more and less than 40 seconds ◎: Yield time is 40 seconds or more The gypsum board specimen was also evaluated in the same manner as above. The test piece of gypsum board is obtained by laminating a required number of commercially available gypsum boards and having the same thickness as the test piece of the filler for hulling.
(3) Test results The evaluation results are shown in Table 1 above. The fluids S1 to S6 and the filler for hulls formed by curing them showed good results in at least one of the tests.

なお、圧縮強度の試験において、S6の試験体は硬化しなかったため、試験を行うことができなかった。また、石こうボードの試験体は、試験荷重を加えたとき、試験体を構成する石こうボードの薄板同士がずれてしまい、試験を行うことができなかった。   In the compressive strength test, the test specimen of S6 could not be tested because it did not cure. Moreover, when the test load of the gypsum board was applied with the test load, the thin plates of the gypsum board constituting the test body were displaced from each other, and the test could not be performed.
