Description
本発明は、上下及び左右に接合される外装材の施工に用いられ、特に左右に接合される外装材に跨るよう固定される固定金具及びこの金具を用いた外装材の施工構造に関するものである。 The present invention relates to a construction of an exterior material that is joined vertically and laterally, and particularly relates to a fixing bracket that is fixed so as to straddle the exterior material that is joined to the left and right, and a construction structure of the exterior material using the fixture. .
従来から、特開2000−240252号公報に示されるように、上下及び左右に接合される外装材の左右接合部に、左右に位置する外装材に跨るよう設けられる固体金具が知られている。この固定金具は、例えば、図7に示すように、上下及び左右に接合される外装材(1)の左右接合部(2)に、左右の外装材(1)に跨るよう設けられ、外装材(1)を建物躯体の外壁部(3:図示せず)に固定するものであって、平板状の固定板部(6)と、固定板部(6)の中程に固定板部(6)より前方に突出するよう設けられた水平片(8)と、水平片(8)の前端に下方に向うよう設けられた第一支持片(9)と、水平片(8)の前端両側部に左右それぞれの外装材に対応し上方に向うよう設けられた第二支持片(10)とを備えている。 Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 2000-240252, there is known a solid metal fitting provided at a left and right joint portion of an exterior material to be joined vertically and laterally so as to straddle the exterior material located on the left and right. For example, as shown in FIG. 7, the fixing bracket is provided at the left and right joint portions (2) of the exterior material (1) that is joined vertically and laterally so as to straddle the left and right exterior materials (1). (1) is fixed to the outer wall portion (3: not shown) of the building frame, and the fixed plate portion (6) is arranged in the middle of the flat fixed plate portion (6) and the fixed plate portion (6). ) A horizontal piece (8) provided to protrude further forward, a first support piece (9) provided to face downward at the front end of the horizontal piece (8), and both sides of the front end of the horizontal piece (8) And a second support piece (10) provided to face upward corresponding to the left and right exterior materials.
そして、外装材(1)を施工する場合には、釘等の固定具(4:図示せず)によりこの固定金具を建物躯体の外壁部(3:図示せず)に固定し、第一支持片(9)により下方に位置する左右の外装材(1)の上端部(15)を支持し、水平片(8)の前端両側部にそれぞれ設けられた第二支持片(10)により上方に位置する左右それぞれの外装材(1)の下端部(16)を支持するものである。 And when constructing the exterior material (1), this fixture is fixed to the outer wall part (3: not shown) of the building frame with a fixture such as a nail (4: not shown), and the first support The upper ends (15) of the left and right exterior materials (1) positioned below are supported by the pieces (9), and the upper portions are supported by the second support pieces (10) provided on both sides of the front end of the horizontal pieces (8). It supports the lower end part (16) of each of the left and right exterior materials (1).
したがって、この場合には、水平片(8)の前端両側部に左右それぞれの外装材に対応するよう第二支持片(10)が設けられているため、この固定金具を用いて外装材(1)を施工した場合、一つの固定金具により左右の外装材(1)を同時に固定することができ、施工性を向上させることが可能になるものである。 Therefore, in this case, since the second support pieces (10) are provided on both sides of the front end of the horizontal piece (8) so as to correspond to the left and right exterior materials, the exterior material (1 ), It is possible to fix the left and right exterior materials (1) at the same time with one fixing bracket, thereby improving the workability.
しかしながら、この場合には、外装材(1)の裏面が平板状の固定板部(6)の表面にほぼピッタリと接触した状態で施工されるため、外装材(1)と建物躯体の外壁部(3:図示せず)との間にほとんど隙間が無く、外装材(1)の裏面等に結露を生じることがあった。近年では、外装材(1)と建物躯体の外壁部(3:図示せず)との間に通気層(17:図示せず)を設ける所謂通気工法が標準施工として採用されており、この固定金具を用いて通気層(17:図示せず)を形成するには、建物躯体の外壁部(3:図示せず)に別途通気用胴縁等を設ける必要があり、施工が非常に煩雑になると共に通気用胴縁等の切断により廃材が増加するという問題があった。 However, in this case, since the back surface of the exterior material (1) is constructed in a state in which the back surface of the exterior plate (1) is in close contact with the surface of the flat plate-like fixed plate portion (6), the exterior material (1) and the outer wall portion of the building frame (3: not shown) There was almost no gap between them and dew condensation sometimes occurred on the back surface of the exterior material (1). In recent years, a so-called ventilation method in which a ventilation layer (17: not shown) is provided between the exterior material (1) and the outer wall (3: not shown) of the building frame has been adopted as a standard construction. In order to form a ventilation layer (17: not shown) using metal fittings, it is necessary to separately provide a ventilation trunk edge or the like on the outer wall (3: not shown) of the building frame, which is very complicated. At the same time, there is a problem that waste materials increase due to cutting of the ventilating trunk edge and the like.
また、同種の固定金具として、実開平5−830号公報に示されるようなものも知られている。この固定金具は、例えば、図8及び図9に示すように、上下に接合される外装材(1)の上下接合部に設けられ、外装材(1)を建物躯体の外壁部(3)に固定するものであって、固定具(4)が挿通される小孔(5)が所定位置に設けられた平板状の固定板部(6)と、固定板部(6)の左右両端に固定板部(6)より前方に突出するよう設けられた凸条部(7)と、固定板部(6)の中程に固定板部(6)より前方に突出するよう設けられた水平片(8)と、水平片(8)の前端中央部に下方に向うよう設けられた第一支持片(9)と、水平片(8)の前端両側部に上方に向うよう設けられた第二支持片(10)とを備えている。 Moreover, what is shown by Japanese Utility Model Laid-Open No. 5-830 is known as the same type of fixing bracket. For example, as shown in FIGS. 8 and 9, the fixing bracket is provided at the upper and lower joints of the exterior material (1) to be joined vertically, and the exterior material (1) is attached to the outer wall (3) of the building frame. A fixed plate portion (6) having a small hole (5) through which the fixture (4) is inserted and fixed at a predetermined position, and fixed to both left and right ends of the fixed plate portion (6). A ridge (7) provided so as to protrude forward from the plate portion (6), and a horizontal piece provided so as to protrude forward from the fixed plate portion (6) in the middle of the fixed plate portion (6). 8), a first support piece (9) provided so as to face downward at the center of the front end of the horizontal piece (8), and a second support provided so as to face upward on both sides of the front end of the horizontal piece (8). And a piece (10).
そして、外装材(1)を施工する場合には、ビスからなる固定具(4)を固定板部(6)の小孔(5)に挿通することによりこの固定金具を建物躯体の外壁部(3)に固定し、第一支持片(9)により下方に位置する外装材(1)の上端部(15)を支持し、第二支持片(10)により上方に位置する外装材(1)の下端部(16)を支持するものである。 And when constructing the exterior material (1), the fixture (4) made of screws is inserted into the small hole (5) of the fixing plate portion (6) to attach the fixing bracket to the outer wall portion ( 3), the upper end portion (15) of the exterior material (1) positioned below is supported by the first support piece (9), and the exterior material (1) positioned above by the second support piece (10). The lower end part (16) of this is supported.
したがって、この場合には、固定板部(6)の左右両端に固定板部(6)より前方に突出するよう凸条部(7)が設けられているため、この固定金具を用いて外装材(1)を施工した場合、別途通気用胴縁等を設けることなく、外装材(1)と建物躯体の外壁部(3)との間に通気層(17)を形成することができ、外装材(1)の裏面等に結露が生じるのを防止することが可能になるものである。 Accordingly, in this case, since the protruding strips (7) are provided at the left and right ends of the fixed plate portion (6) so as to protrude forward from the fixed plate portion (6), the exterior member is formed using the fixed bracket. When (1) is constructed, a ventilation layer (17) can be formed between the exterior material (1) and the outer wall (3) of the building frame without providing a separate vent edge or the like. It is possible to prevent dew condensation on the back surface of the material (1).
しかしながら、この固定金具にあっては、上下及び左右に接合される外装材(1)の左右接合部(2)に、左右の外装材(1)に跨るよう設けられることについては配慮されておらず、この固定金具を用いて外装材(1)を施工した場合、水平片(8)の前端両側部にそれぞれ設けられた第二支持片(10)により、左右それぞれの外装材(1)が支持され、支持された外装材(1)は、その左右接合部(2)において、凸条部(7)により外装材(1)と固定板部(6)との間に空間部を生じることになる。このように、外装材(1)は、その裏面において、凸条部(7)にのみ接触、支持されることになるため、左右接合部(2)で段差やガタツキが発生し易く、十分な意匠性や防水性が得られないという問題があった。 However, in this fixing bracket, the left and right joints of the outer package to be joined vertically and horizontally (1) (2), taken into consideration for the Ru provided to straddle the left and right of the outer package (1) When the exterior material (1) is constructed using this fixing bracket, the left and right exterior materials (1) are respectively provided by the second support pieces (10) provided on both sides of the front end of the horizontal piece (8). Is supported, and the supported exterior material (1) has a space portion between the exterior material (1) and the fixed plate portion (6) by the ridges (7) at the left and right joints (2). It will be. In this way, the exterior material (1) is in contact with and supported only by the ridges (7) on the back surface thereof, so that a step or rattle is likely to occur at the left and right joints (2), which is sufficient. There was a problem that designability and waterproofness could not be obtained.
本願発明は、上記背景技術に鑑みて発明されたものであり、その課題は、上下及び左右に接合される外装材の左右接合部に、左右の外装材に跨るよう設けられても、別途通気用胴縁等を設けることなく、外装材と建物躯体の外壁部との間に通気層を形成して、外装材の裏面等に結露が生じることを防止することができるとともに、左右接合部での段差やガタツキの発生を無くして、十分な意匠性や防水性を得ることができる固定金具及びこの金具を用いた外装材の施工構造を提供することである。 The present invention has been invented in view of the above-mentioned background art, and the problem is that a separate ventilation is provided even if the left and right joints of the exterior material to be joined vertically and laterally are provided to straddle the left and right exterior materials. It is possible to form a ventilation layer between the exterior material and the outer wall of the building frame without providing a body rim, etc., and to prevent condensation on the back surface of the exterior material. It is an object to provide a fixing bracket capable of obtaining sufficient designability and waterproofness, and a construction structure of an exterior material using the bracket without the occurrence of the step or backlash.

The front end portion of the cut portion is divided into three, and the central portion thereof is bent obliquely upward to form a first support piece (9), which supports the exterior packaging material (1) located above and is oblique It is designed so that the outer packaging material (1) located above depending on the shape is attracted to the outer wall portion (3) side and brought into close contact with the lower packaging material (1).
また、先端部の両端部は下方に向かうよう折り曲げられて第二支持片(10)が形成されている。この第二支持片(10)には、凸条部(7)の前方に伸びたストッパー部(10a)が形成されており、このストッパー部(10a)の後端が凸条部(7)の表面に当たることで上方に位置する外装材(1)の荷重により水平片(8)および第二支持片(10)が下がるのを防止するものである。また、第二支持片(10)の垂下片(10b)は階段状に形成されており、水平片(8)および第二支持片(10)の剛性を向上させるものである。 Moreover, the both ends of the front-end | tip part are bent so that it may go below, and the 2nd support piece (10) is formed. The second support piece (10) is formed with a stopper portion (10a) extending forward of the ridge portion (7), and the rear end of the stopper portion (10a) is the ridge portion (7). By hitting the surface, the horizontal piece (8) and the second support piece (10) are prevented from being lowered by the load of the exterior packaging material (1) positioned above. Moreover, the drooping piece (10b) of the second support piece (10) is formed in a step shape, and improves the rigidity of the horizontal piece (8) and the second support piece (10).
また、固定板部(6)の中程には、この切り込み部に相当する開放部(20)が形成されることになり、金具の軽量化を図ることができるとともに、紐等を通して施工時に数多く携帯できるものである。 In addition, an open portion (20) corresponding to the cut portion is formed in the middle of the fixed plate portion (6), so that the weight of the metal fitting can be reduced, and a large number can be provided during construction through a string or the like. It can be carried.
固定板部(6)の下部水平端には、凸条部(7)と略同一高さとなるよう薄板の下端部を固定板部(6)に対して略直角となるよう折り曲げてガイド片(11)が形成されており、左右それぞれの外装材(1)の裏面側を支持して左右接合部(2)での段差やガタツキの発生を無くすように設計されている。また、固定板部(6)の下部には、固定金具の剛性を向上させガイド片(11)の直線度を確保するために水平方向全長に亘って前方に膨出するよう断面略円弧状の下部補強リブ(19)がガイド片(11)に近接させて形成されている。 At the lower horizontal end of the fixed plate portion (6), the lower end of the thin plate is bent so as to be substantially the same height as the ridge portion (7) so as to be substantially perpendicular to the fixed plate portion (6). 11) is formed, and is designed to support the back side of each of the left and right exterior materials (1) and eliminate the occurrence of steps and backlash at the left and right joints (2). Further, the lower part of the fixed plate portion (6) has a substantially arc-shaped cross section so as to bulge forward over the entire length in the horizontal direction in order to improve the rigidity of the fixed fitting and to ensure the straightness of the guide piece (11). A lower reinforcing rib (19) is formed adjacent to the guide piece (11).
水平片(8)の中央部には、下方に且つ固定板部(6)と直交方向に水平片(8)の一部を切り起こして垂直片(13)が形成されており、下方に位置する左右それぞれの外装材(1)が伸縮して位置ずれするのを防止するものである。また、水平片(8)の一部を切り起こして垂直片(13)を形成することで水平片(8)に隣接して開口(14)が形成されており、外装材(1)の裏面側に浸入した雨水や裏面側に生じた結露水が水平片(8)に溜まり外装材(1)に対し吸水や凍害等の悪影響を及ぼすのを防止するものである。 At the center of the horizontal piece (8), a vertical piece (13) is formed by cutting and raising a part of the horizontal piece (8) downward and in a direction orthogonal to the fixed plate portion (6). This prevents the left and right exterior materials (1) from expanding and contracting and being displaced. Moreover, the opening (14) is formed adjacent to the horizontal piece (8) by cutting and raising a part of the horizontal piece (8) to form the vertical piece (13), and the back surface of the exterior material (1). This prevents rainwater that has entered the side and condensed water that has formed on the back side from collecting on the horizontal piece (8) and adversely affecting the exterior material (1) such as water absorption and frost damage.
