Description

TECHNICAL FIELD The present invention relates to a mounting structure and mounting method for an exterior material on an outer wall of a building.

In an existing building or a newly constructed building, an exterior material is sometimes attached to the outside of the outer wall of the building in order to enhance the appearance design. For example, the outer wall on the front side including the entrance door of the building, which faces the aisle in front of the building, can be a symbolic outer wall that affects the exterior design of the building. Exterior materials may be attached to part of the facade. In addition, in a store that attracts customers, an exterior material having an advertisement board may be attached to the outer wall on the front side of the store.

When attaching such exterior materials to the outer wall of the building, if a frame for attaching the exterior materials is provided on the outer periphery of the building separately from the building's structural frame, it will be necessary to construct a foundation for it. The construction will be large-scale, and the load will increase in terms of construction period and construction cost. Therefore, there has been proposed an exterior material attachment device for attaching an exterior material to the surface of a building. In this device, a mounting bracket is inserted through a hole penetrating the outer wall of the ALC and fixed to the frame of the building. In the mounting bracket, a fixed metal fitting and a slide metal fitting are assembled so as to be slidable in the longitudinal direction. The fixing hardware of the mounting bracket has a horizontally elongated hole provided parallel to the longitudinal direction and a bolt hole drilled in the slide hardware, and is fixed by passing a bolt through the horizontally elongated hole and the bolt hole (see, for example, Patent Document 1).

Japanese Patent No. 3709556

However, the exterior material attachment device described in Patent Document 1 attaches the vertical furring strips and the horizontal furring strips to the exterior material fitting device, and attaches the exterior materials to these vertical furring strips and the horizontal furring strips. There is no disclosure of how specifically the facing material is attached. It is easy to understand that if the exterior materials are fixed to all of the vertical furring strips and the horizontal furring strips with bolts or the like, it would take a lot of time and effort to attach the exterior materials. In addition, in the exterior material mounting device described in Patent Document 1, the fixed hardware and the slide hardware are slidably assembled, and both are fixed by bolts provided in the direction across the plate, so that the mounting hardware can be extended and contracted in the length direction. Therefore, it cannot be denied that the structure is complicated and the manufacturing cost is high.

Hereinafter, the mounting structure and mounting method of the exterior material according to the embodiment will be described with reference to the accompanying drawings. In this specification and drawings, substantially the same components may be denoted by the same reference numerals, thereby omitting duplicate descriptions.

[Mounting Method and Mounting Structure of Exterior Material According to Embodiment]
A mounting method and mounting structure for an exterior material according to an embodiment will be described with reference to FIGS. 1 to 7. FIG. Here, FIGS. 1, 4 and 7 are process diagrams for explaining, in order, the mounting method of the exterior material according to the embodiment, and FIG. FIG. 10 shows. In each figure, the pattern of the outer wall panel is illustrated mainly on the side surface of the facade 10 to which the exterior material is attached, and the pattern of the other wall surfaces is omitted.

In the explanation of the mounting method and mounting structure of the exterior material according to the embodiment, the target is a steel-framed two-story house. The house 100 shown in FIG. 1 has an entrance door 101, and the exterior wall side of the house 100 where the entrance is recessed inward is the facade 10 (a surface that is symbolic in appearance) of the house 100. Of this facade 10, A portion of the outer wall region projecting outward is used as an attachment region for the exterior material. The house 100 is constructed by attaching rectangular outer wall panels 11 made of ceramic siding material or the like in the vertical direction and the horizontal direction (width direction) to a structural framework formed of through pillars and large beams (not shown). The outer wall is formed. For example, the structural frame is formed by connecting columns made of square steel pipes with large beams made of shaped steel materials such as H-shaped steel with bolts, etc. , braces made of molded steel or the like, ladder-type load-bearing wall frames, etc. are built into the gate-type frame.

Vertical joints 12 are formed between rows of the plurality of outer wall panels 11 stacked in the vertical direction. In the illustrated example, vertical joints 12 are provided for each of the outer wall panels 11 stacked in two rows in the vertical direction. In each vertical joint 12, three carry-out members 20 are carried out at intervals in the mounting region of the exterior material above the facade 10 (upper half of the side surface). Therefore, a total of nine extension members 20 are illustrated for three vertical joints 12 . The number of carrying out members 20 is set according to the rigidity of the carrying out members 20 and the weight of the exterior material supported by each carrying out member 20. For example, one vertical base member is supported by two upper and lower carrying members 20. There may be.

The carry-out member 20 is formed of a gusset plate having bolt holes, and is connected by welding or the like to a column made of, for example, a rectangular steel pipe or the like that forms the structural framework. In the newly built house 100, the gusset plate 20 is brought out from the vertical base material 12 in anticipation of the installation of the exterior material. In addition, in the existing house 100, the outer wall panel 11 around the vertical joint 12 is removed to expose the side of the pillar, and the gusset plate 20 is fixed to the pillar while reinforcing the pillar as necessary. The gusset plate 20 is brought out by reattaching the panel 11 .

By positioning the carrying-out material 20 at the vertical joint 12, the carrying-out material 20 can be carried out without disturbing the alignment of the outer wall panels 11 arranged in the vertical direction and the horizontal direction. Although illustration is omitted, in addition to the vertical joint 12, the side surface having the horizontal joint may be configured such that the carrying material is brought out from the horizontal joint.

Next, with reference to FIGS. 2 and 3, the vertical base material fixed to the plurality of projecting materials 20 projecting from each vertical joint 12 will be described. Here, FIG. 2 is a perspective view of an example of a vertical base member to which fixing metal fittings and engaging metal fittings are attached, and FIG. 3 is a view taken along line III--III in FIG. The illustrated vertical substrate 30 is formed from angle steel. A total of six bolt holes 31 (2 x 3 pairs) are opened at positions corresponding to the bolt holes of the three gusset plates 20 protruding from one vertical joint 12 in one metal piece of the angle iron. It is

On the other hand, on the other metal piece of the angle iron 30, a fixing metal fitting 40 is fixed with a bolt nut 61 through a bolt hole (not shown) above it, and an engaging metal fitting 50 is fixed to the bolt hole (not shown) below it. It is fixed with a bolt nut 62 through.

That is, in the mounting method of the illustrated example, prior to mounting the vertical base member 30 to the carrying member 20, the fixing metal fittings 40 and the engaging metal fittings 50 are ground assembled to the vertical base member 30. FIG. Therefore, in the mounting method of the illustrated example, when the four vertical base members 30 are mounted on the outer wall of the house 100, the fixing metal fittings 40 and the engaging metal fittings 50 are attached to the four vertical base members 30 in advance.

The fixture 40 is manufactured in a three-dimensional shape by cutting and bending a steel plate. The fixing bracket 40 has a mounting piece 41 bolted to the vertical base material 30 , a fixing piece 42 to which the exterior material is fixed, and an engaging piece 43 to engage with the corner of the vertical base material 30 . . As shown in FIG. 3, a first bolt hole 42a formed in the fixed piece 42 has a threaded hole wall surface, and a bolt 63 is screwed from below and fixed to the fixed piece 42. As shown in FIG. That is, not only is the fixing bracket 40 attached to the vertical base member 30, but also the vertical base member 30 is attached to the carry-out member 20 in a state in which the bolt 63 is fixed to the fixing bracket 40 in a posture facing upward. .

For example, the bolt 63 is only screwed into the threaded portion of the fixing piece 42 having a thickness of several millimeters. The state of being fixed to the fixing piece 42 of the fixing metal fitting 40 can be maintained.

As shown in FIG. 3, after the vertical base member 30 is attached to the carrying member 20, the bolt 63 fixed in an upward posture to the fixture 40 already attached to the vertical base member 30 is The bolt holes of the upper horizontal rails (see FIGS. 5 and 6) forming the exterior material are inserted, and nuts 64 are tightened and fixed.

On the other hand, the engaging metal fitting 50 is also manufactured in a three-dimensional shape by performing cutting and bending on a steel plate. The engaging fittings 50 are engaged with a mounting piece 51 bolted to the vertical base material 30 , a mounting piece 52 placed with the exterior material engaged, and a corner of the vertical base material 30 . It has an engaging piece 53 that engages. The mounting piece 52 has a stepped shape, bends 90 degrees from the mounting piece 51 extending in the vertical direction, extends horizontally, and further bends 90 degrees and extends vertically. This vertically extending metal strip is adapted to be engaged with the lower rung (see FIG. 5) forming the sheathing.

Both the engaging pieces 43 of the fixing metal fittings 40 and the engaging pieces 53 of the engaging metal fittings 50 are engaged with the corners of the angle steel metal pieces forming the vertical base material 30 . By engaging the fixing metal fitting 40 and the engaging metal fitting 50 with one corner of the vertical base material 30 via the engaging pieces 43, 53 in this manner, the mounting pieces 41, 51 are attached to the vertical base material. Even if it is fixed to 30 with one bolt and nut, the correct attitude of the fixing metal fitting 40 and the engaging metal fitting 50 can be maintained. If the engaging pieces 43 and 53 were not provided, the horizontal posture of the fixing piece 42 and the vertical posture of the mounting piece 52 would not be properly maintained unless the mounting pieces 41 and 51 were fixed with two or more bolts and nuts. It is difficult to do so, and they will rotate immediately, and it may take time and effort to correct these postures to the correct posture when attaching the exterior material.

In addition, in a state where the engaging pieces 43 and 53 are engaged with one corner of the vertical base member 30, the fixing metal fitting 40 and the engaging metal fitting 50 are tightened with a nut using an electric screwdriver or the like. In this case, the fixing metal fittings 40 and the engaging metal fittings 50 do not co-rotate, and quick attachment can be realized.

Next, as shown in FIG. 4, the vertical base member 30, in which the fixing metal fittings 40 and the engaging metal fittings 50 are assembled, is moved to the installation position via a temporary scaffolding (not shown) or via an aerial work vehicle or the like. It is conveyed and attached to a set of carry-out materials 20 at upper, middle and lower positions carried out from each vertical joint 12.例文帳に追加The vertical base members 30 are attached by positioning the bolt holes of the gusset plates 20 and the corresponding bolt holes of the vertical base members 30 and fixing them with bolts.

In FIG. 4, one vertical base member 30 is attached to each pair of carrying members 20 at the left and right ends. More specifically, the vertical base member 30 shown in FIG. 2 is attached to the three carrying members 20 of the leftmost set in FIG. 2 is a vertical base member having a line symmetry relationship with the vertical base member 30 shown in FIG. are engaged with opposite corners).

Further, in FIG. 4, vertical base members 30 are arranged on the left and right sides of the three carrying members 20 in the central group to secure them. That is, the set of three carrying out members 20 in the center supports two vertical base members 30 for fixing the left and right exterior members arranged on the left and right sides thereof. Therefore, it is possible to attach a plurality of exterior materials while reducing the number of carrying materials 20 as much as possible. The illustrated example has a central set of supporting members 20 that support two vertical base members 30. In a building with a laterally expanded facade, the supporting members 20 corresponding to the illustrated central set This effect becomes even more pronounced in a configuration in which the number of (sets of projecting beams that support the left and right exterior materials) is greater.

As described above, by attaching the unique vertical base material 30 to each set of the projecting materials 20 projecting from the vertical joints 12 of the outer wall of the building 100, preparation for installation of the exterior material is completed. In FIG. 4, four vertical furrings 30 are attached to the facade 10, and one cladding will be supported against a set of two vertical furrings 30 (see FIG. 4). The above is the process of installing the vertical base material).

Next, with reference to FIGS. 5 and 6, an example of an exterior material attached to the vertical base material 30 will be described. The illustrated cladding 90 is horizontally disposed in spaced relation to an upper rung 71 formed from lip channel steel and a lower rung 72 also formed from lip channel steel, It has a plurality of vertical louvers 80 fixed to the upper and lower horizontal beams 71,72.

As shown in FIG. 5, the upper rung 71 is assembled with the lip channel opening facing upwards, while the lower rung 72 is assembled with the lip channel opening facing downwards. Assembled in posture. As shown in FIG. 6, the upper horizontal beam 71 is inserted with a bolt 63 (see FIG. 2) that is fixed in an upward attitude to the fixing bracket 40 attached to the vertical base member 30. , and second bolt holes 71a. In addition, as shown in FIG. 5, the lower horizontal beam 72 is formed by bending a portion of the metal piece on the side of the vertical louver 80 of the lip channel steel, and the bent portion is connected to the vertical louver 80. An engagement recess 72a is formed to form a gap therebetween. Note that the lower horizontal beam 72 may be configured without the engaging recess 72a as in the illustrated example. In this embodiment, the mounting pieces 52 shown in FIG. An engaging fitting having a mounting piece cut off on either the left or right half from the center is applied, and the exterior material 90 is applied to the engaging fitting in which the mounting piece escapes from the vertical louver 80 in this way. be placed.

In this way, the exterior material 90 includes the upper and lower horizontal beams 71 and 72, and the members fixed to the horizontal beams 71 and 72 to create various appearance designs (in the illustrated example, a plurality of vertical louvers 80). have The vertical louver 80 can be made of various materials such as wood, resin, and metal, and each material has its own unique appearance design and atmosphere. Further, instead of arranging the vertical louvers 80 perpendicularly to the horizontal beams 71 and 72 as in the illustrated example, they may be arranged in an oblique direction, or vertical louvers such as round bars may be applied. It can create a warm atmosphere. Further, for example, when the vertical louver 80 is made of a wooden crosspiece, the upper and lower horizontal crosspieces 71 and 72 are also made of the same wooden crosspiece.

As described above, the exterior material 90 may have various forms, but hereinafter, other forms will be exemplified while omitting the drawings.

(A) an exterior material having a set of horizontal beams and a plurality of louvers (illustrated example);
(B) an exterior material having a set of horizontal beams and planting panels;
(C) an exterior material having a pair of said rungs and a shutter;
(D) a cladding having a set of rungs and an advertising billboard;
(E) An exterior material having a set of horizontal beams and a solar panel can be mentioned.

If the building 100 is a store or the like, an advertising bulletin board (commercial billboard) can be applied as the exterior material 90, and the advertising bulletin board may be one with letters or pictures stamped or painted, or an electronic bulletin board. and so on. Moreover, the exterior material having a solar panel can produce not only power generation by the solar panel but also a technological image by exposing the solar panel on the wall surface.

As shown in FIG. 7, by fixing one exterior material 90 to two vertical base materials 30, in the illustrated example, the two exterior materials 90 are used to attach the exterior material to the facade 10. A mounting structure 200 for the exterior material is formed.

A more detailed description of the method of attaching the exterior material 90 to the vertical base material 30 is as follows. By inserting the mounting pieces 52 of the engaging metal fittings 50 attached to the material 30 (in the Z direction in FIG. 5), the left and right engaging metal fittings 50 of the exterior material 90 are engaged with each other. With the mounting piece 52 inserted into the engaging recess 72a in this way, the upper horizontal beam 71 of the exterior material 90 is carried above the fixing piece 42 and fixed to the fixing metal fitting 40 in a state facing upward. By inserting the bolts 63 through the second bolt holes 71 a of the horizontal rails 71 , the exterior material 90 is temporarily fixed to the two vertical base materials 30 on the left and right sides.

By tightening the bolts 63 protruding upward from the second bolt holes 71a of the upper horizontal rails 71 to the temporarily fixed exterior material 90 with nuts 64 (see FIG. 3), the exterior material 90 is removed. is fixed, and the exterior material 90 is attached to the outer wall (the above is the exterior material attachment step).

As described above, when the exterior material 90 is attached, the exterior material 90 is not all bolted to the vertical base material 30, but the lower part of the exterior material 90 is engaged with the engaging metal fittings 50. By fixing only the upper portion to the fixing metal fitting 40 with bolts, the mountability of the exterior material 90 is improved. This good mountability becomes even more remarkable as the area of the exterior material 90 increases or as the number of exterior materials 90 increases.

Further, when the exterior material 90 is attached, since the bolt 63 is already fixed to the upper fixing metal fitting 40 in a posture facing upward, the second bolt hole 71a of the upper horizontal beam 71 is inserted into the bolt 63. The nut can be quickly tightened, and this also provides excellent mountability.
