Abstract

PROBLEM TO BE SOLVED: To provide a base fixing bracket capable of suppressing a consumption of energy resources by a heating and cooling appliance or the like.SOLUTION: An L-shaped fitting 14 is attached to a pedestal 16 via a heat-insulating member. In a base fixing bracket 10 fixed to a concrete wall 22 of a building, the L-shaped fitting 14 is fixed to the concrete wall 22 with an anchor bolt 18. At this time, the anchor bolt 18 is fitted to a cavity part of the heat-insulating member and is not in contact with the L-shaped fitting 14, so that temperature of the L-shaped fitting 14 is not transmitted to the concrete wall 22. Furthermore, the pedestal 16 for the L-shaped fitting has a predetermined thickness and the L-shaped fitting 14 is fixed apart a certain distance from the concrete wall 22. Therefore, the temperature of the L-shaped fitting 14 is not transmitted to the concrete wall 22. Consequently, the indoor of the building cannot be affected by an outside air temperature and a consumption of energy resources increased by a change in the outside air temperature can be suppressed when performing indoor cooling and heating.

Description

本発明は、下地を建築物の壁に固定するための下地固定用ブラケットに関するものである。 The present invention relates to a base fixing bracket for fixing a base to a wall of a building.

建築物の外壁工事では、建築物を風雨から守る外装用パネル等の外装材を下地に取り付ける工事が行われる。下地は、アングル材（山形鋼）等の下地金属を縦横に組んだ骨組みであり、格子状に組まれる。また、下地は、Ｌ字状のブラケット（Ｌ字金具）を介してアンカーボルトで建築物のコンクリート壁に固定される（例えば、特許文献１）。 In exterior wall construction of a building, construction is performed in which exterior materials such as exterior panels that protect the building from wind and rain are attached to the base. The base is a framework in which base metals such as angle materials (yamagata steel) are assembled vertically and horizontally, and is assembled in a lattice shape. Further, the base is fixed to a concrete wall of a building with an anchor bolt via an L-shaped bracket (L-shaped metal fitting) (for example, Patent Document 1).

実公平６−７１４０号公報（図２、図３）Japanese Utility Model Publication No. 6-7140 (FIGS. 2 and 3)

特許文献１の外装用パネルでは、下地の縦材はブラケット（Ｌ字金具）を介してアンカーボルトで建築物のコンクリート壁に固定されている。
外装用パネルの温度（表面温度）は、夏であれば６０℃〜１００℃程度になり、冬であればマイナス温度にもなる。
特許文献１に記載のブラケットによると、外装用パネルの温度は、金属のブラケットおよびアンカーボルトを介して建築物のコンクリート壁に伝わる。すなわち、夏は、外装用パネルの温度がコンクリート壁を通じて建築物室内に伝わり、建築物の室内温度が上昇する。冬は、室内温度が低下する。この場合、暖冷房機器等を用いて室内を一定の温度に保つようにすると、電気、ガス、灯油等のエネルギー資源の消費が増大する。このようにＬ字金具からなる従来のブラケットは、エネルギー資源を消費する欠点があった。 In the exterior panel of Patent Document 1, the underlying vertical member is fixed to a concrete wall of a building with an anchor bolt via a bracket (L-shaped metal fitting).
The temperature (surface temperature) of the exterior panel is about 60 ° C. to 100 ° C. in summer, and a negative temperature in winter.
According to the bracket described in Patent Document 1, the temperature of the exterior panel is transmitted to the concrete wall of the building via the metal bracket and the anchor bolt. That is, in summer, the temperature of the exterior panel is transmitted to the building room through the concrete wall, and the room temperature of the building rises. In winter, the room temperature decreases. In this case, consumption of energy resources such as electricity, gas, and kerosene increases if the room is kept at a constant temperature using a heating / cooling device or the like. Thus, the conventional bracket which consists of L-shaped metal fittings had the fault of consuming energy resources.

本発明は、上記欠点を解決するものであって、暖冷房機器等によるエネルギー資源の消費を抑える下地固定用ブラケットを提供することを目的とするものである。 The present invention solves the above-described drawbacks, and an object of the present invention is to provide a base fixing bracket that suppresses consumption of energy resources by a heating / cooling device or the like.

本発明の下地固定用ブラケットは、略筒状に形成された断熱性部材と、その断熱性部材が貫通可能な孔部を有するＬ字金具と、前記断熱性部材を嵌入する貫通孔部が形成され所定の厚さを有するＬ字金具用台座とを備え、前記断熱性部材が筒状の脚部とその脚部の上部に形成される断熱部とからなるものであり、前記Ｌ字金具用台座に前記Ｌ字金具をその両孔部が連通するように取り付け、当該連通する両孔部に前記断熱性部材の脚部を挿入して形成されるようにしたものである。 The base fixing bracket of the present invention includes a heat insulating member formed in a substantially cylindrical shape, an L-shaped metal fitting having a hole through which the heat insulating member can pass, and a through hole portion into which the heat insulating member is fitted. And a base for the L-shaped metal fitting having a predetermined thickness, wherein the heat insulating member is composed of a cylindrical leg portion and a heat insulating portion formed on an upper portion of the leg portion. The L-shaped metal fitting is attached to a pedestal so that both hole portions thereof communicate with each other, and the leg portions of the heat insulating member are inserted into the both communicating hole portions.

本発明の下地固定用ブラケットは、外装用パネルの温度が建築物のコンクリート壁に伝わることを遮断するものである。これにより、建築物の室内が外気温度の影響を受けないようにすることができ、暖冷房機器等の暖房又は冷房に要するエネルギー資源の消費を抑えることができる。 The base fixing bracket of the present invention blocks the temperature of the exterior panel from being transmitted to the concrete wall of the building. Thereby, the interior of the building can be prevented from being affected by the outside air temperature, and consumption of energy resources required for heating or cooling of the heating / cooling device or the like can be suppressed.

本発明の下地固定用ブラケット１０は、略筒状の断熱性部材１２と、断熱性部材１２が貫通可能な孔部１４ａを有するＬ字金具１４と、断熱性部材１２を嵌入する貫通孔部１６ａを有するＬ字金具用台座１６とを備える。Ｌ字金具１４は、金属板をＬ字状に曲折したＬ字型断面の取付金具であり、特許文献１に記載のＬ字状のブラケットと同じものである。Ｌ字金具１４が下地に固定される一片１４ｂには、ネジ等の固定手段を打ち込む穴部１４ｃが数個形成されており、他片１４ｄの中央部に孔部１４ａが形成されている。 A base fixing bracket of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing the components of the base fixing bracket of the present invention. FIG. 2 is a diagram illustrating a state in which the base is fixed using the base fixing bracket of FIG.
The base fixing bracket 10 of the present invention includes a substantially cylindrical heat insulating member 12, an L-shaped metal fitting 14 having a hole portion 14a through which the heat insulating member 12 can pass, and a through hole portion 16a into which the heat insulating member 12 is fitted. And an L-shaped bracket base 16. The L-shaped bracket 14 is a mounting bracket having an L-shaped cross section obtained by bending a metal plate into an L shape, and is the same as the L-shaped bracket described in Patent Document 1. Several holes 14c into which fixing means such as screws are driven are formed in one piece 14b on which the L-shaped metal fitting 14 is fixed to the base, and a hole 14a is formed in the center of the other piece 14d.

断熱性部材１２は、筒状の脚部１２ａと、その脚部１２ａの上部に形成される断熱部１２ｂとからなるものである。断熱部１２ｂは、脚部１２ａの上部開口部から水平方向に延出された部分であり、脚部１２ａより径大に形成されている。また、断熱性部材１２は、断熱できる素材、たとえば合成樹脂により形成されている。
図１の断熱部１２ｂの形状は、平座金と同様の形状に形成されているが、この形状に限るものではない。断熱部１２ｂは、アンカーボルト１８を装着したときにアンカーボルト１８のワッシャー１８ａがＬ字金具１４に接しないような形状および大きさに形成されるものであればよい。 The heat insulating member 12 includes a cylindrical leg portion 12a and a heat insulating portion 12b formed on an upper portion of the leg portion 12a. The heat insulating part 12b is a part extending in the horizontal direction from the upper opening of the leg part 12a, and is formed to have a diameter larger than that of the leg part 12a. The heat insulating member 12 is made of a heat insulating material such as a synthetic resin.
Although the shape of the heat insulation part 12b of FIG. 1 is formed in the shape similar to a plain washer, it is not restricted to this shape. The heat insulating portion 12b may be formed in any shape and size so that the washer 18a of the anchor bolt 18 does not contact the L-shaped metal fitting 14 when the anchor bolt 18 is attached.

Ｌ字金具用台座１６は、所定の厚さ（又は高さ）を有するものである。また、台座１６は、断熱できる素材、たとえば合成樹脂により形成され、その表面中央部には、貫通孔部１６ａが形成されている。
なお、図１の台座１６には、台座本体１６ｂの表面（台座１６の上面）にＬ字金具１４の一片１４ｄを装着するための金具押さえ部１６ｃが設けられている。台座本体１６ｂと金具押さえ部１６ｃとの間には隙間２０が形成されており、隙間２０にＬ字金具１４の一片１４ｄを挿入することにより、台座１６にＬ字金具１４を容易に取り付けることができるようになっている。
また、Ｌ字金具用台座１６は、Ｌ字金具１４の一片１４ｄと建築物のコンクリート壁２２（図２）との間に所定の距離を形成するスペーサであってもよく、その形状・構造は特定されるものではない。 The L-shaped bracket base 16 has a predetermined thickness (or height). The pedestal 16 is formed of a heat-insulating material such as synthetic resin, and a through hole 16a is formed at the center of the surface.
The pedestal 16 shown in FIG. 1 is provided with a metal fitting pressing portion 16c for mounting the piece 14d of the L-shaped metal fitting 14 on the surface of the pedestal main body 16b (the upper surface of the pedestal 16). A gap 20 is formed between the pedestal main body 16b and the metal fitting pressing portion 16c. By inserting one piece 14d of the L-shaped metal piece 14 into the gap 20, the L-shaped metal piece 14 can be easily attached to the pedestal 16. It can be done.
The L-shaped bracket base 16 may be a spacer that forms a predetermined distance between the piece 14d of the L-shaped bracket 14 and the concrete wall 22 (FIG. 2) of the building. It is not specified.

続いて、下地固定用ブラケットの組立ておよび下地金具の固定方法を説明する。
Ｌ字金具用台座１６の隙間２０にＬ字金具１４の一片１４ｄを差込み、台座１６にＬ字金具１４を取り付ける（図１）。なお、取り付けた場合、Ｌ字金具１４の孔部１４ａと台座１６の貫通孔部１６ａは、連通するように設けられている。
次に、Ｌ字金具１４の孔部１４ａおよび台座１６の貫通孔部１６ａに断熱性部材１２の脚部１２ａを嵌入又は挿入する。これにより、Ｌ字金具１４は断熱性部材１２を介して台座１６に取り付けられ、下地固定用ブラケット１０が組み立てられる（図１）。
また、Ｌ字金具１４を取り付けた台座１６の裏面（台座１６の底部）を建築物のコンクリート壁面２２に当接させた状態で（図２）、断熱性部材１２の空洞部にアンカーボルト１８を挿入し打ち込むことにより、コンクリート壁２２に下地固定用ブラケット１０を固定することができる。他方、台座１６にＬ字金具１４の他の片１４ｂは、ビス等の固定部材を用いて下地２４（縦材又は横材）に固定する。これにより、下地２４は建築物のコンクリート壁２２に固定される（図２）。
なお、断熱性部材１２の脚部１２ａの長さは、当該脚部１２ａが台座１６の底面から突き出ないように設定されている。 Next, the assembly of the base fixing bracket and the base metal fixing method will be described.
A piece 14d of the L-shaped bracket 14 is inserted into the gap 20 of the L-shaped bracket base 16, and the L-shaped bracket 14 is attached to the base 16 (FIG. 1). In addition, when it attaches, the hole part 14a of the L-shaped metal fitting 14 and the through-hole part 16a of the base 16 are provided so that it may connect.
Next, the leg portion 12 a of the heat insulating member 12 is fitted or inserted into the hole portion 14 a of the L-shaped metal fitting 14 and the through hole portion 16 a of the base 16. Thereby, the L-shaped metal fitting 14 is attached to the base 16 through the heat insulating member 12, and the base fixing bracket 10 is assembled (FIG. 1).
Further, with the back surface of the pedestal 16 to which the L-shaped metal fitting 14 is attached (the bottom portion of the pedestal 16) being in contact with the concrete wall surface 22 of the building (FIG. 2), the anchor bolt 18 is attached to the cavity of the heat insulating member 12. By inserting and driving, the base fixing bracket 10 can be fixed to the concrete wall 22. On the other hand, the other piece 14b of the L-shaped bracket 14 on the pedestal 16 is fixed to the base 24 (vertical material or horizontal material) using a fixing member such as a screw. Thereby, the foundation | substrate 24 is fixed to the concrete wall 22 of a building (FIG. 2).
The length of the leg portion 12 a of the heat insulating member 12 is set so that the leg portion 12 a does not protrude from the bottom surface of the pedestal 16.

建築物のコンクリート壁２２に固定された下地固定用ブラケット１０において（図２）、Ｌ字金具１４は、アンカーボルト１８によりコンクリート壁２２に固定されている。このとき、アンカーボルト１８は断熱性部材１２の空洞部に装着されＬ字金具１４に接していないため、Ｌ字金具１４の温度すなわち図示しない外装用パネルの温度は、コンクリート壁２２に伝わらない。
さらには、Ｌ字金具用台座１６は所定の厚さを有し、Ｌ字金具１４とコンクリート壁２２とは一定の距離離れて固定されるため、Ｌ字金具１４の温度はコンクリート壁２２に伝わらない、すなわち断熱される。また、台座１６を非伝熱性の素材で形成することにより、断熱効果を高めることができる。 In the base fixing bracket 10 fixed to the concrete wall 22 of the building (FIG. 2), the L-shaped metal fitting 14 is fixed to the concrete wall 22 by anchor bolts 18. At this time, since the anchor bolt 18 is mounted in the cavity of the heat insulating member 12 and is not in contact with the L-shaped metal fitting 14, the temperature of the L-shaped metal fitting 14, that is, the temperature of the exterior panel not shown, is not transmitted to the concrete wall 22.
Furthermore, since the L-shaped bracket base 16 has a predetermined thickness, and the L-shaped bracket 14 and the concrete wall 22 are fixed at a certain distance, the temperature of the L-shaped bracket 14 is transmitted to the concrete wall 22. Not insulated, ie insulated. Moreover, the heat insulation effect can be improved by forming the base 16 with a non-heat-conductive material.

本発明の下地固定用ブラケットによると、外装用パネルの温度が建築物のコンクリート壁に伝わることを遮断できる下地構造とすることができる。これにより、建築物の室内が外気温度の影響を受けないようにすることができ、室内の冷暖房を行う際、外気温度の変化によって増大するエネルギー資源の消費を抑えることができる。 According to the base fixing bracket of the present invention, it is possible to provide a base structure that can block the temperature of the exterior panel from being transmitted to the concrete wall of the building. As a result, the interior of the building can be prevented from being affected by the outside air temperature, and energy consumption that increases due to a change in the outside air temperature can be suppressed when the room is air-conditioned.
