Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure of a building constructed by attaching panels to a skeleton, and more specifically to a skeleton made of concrete or steel frame from the panel surface side of a large number of panels mainly composed of metal plates. The present invention relates to a mounted wall structure.

[0002]

2. Description of the Related Art The outer wall of a building constructed by attaching a panel mainly composed of lightweight concrete to a frame made of concrete or steel frame is often of curtain wall type,
It is common to connect a mounting member protruding from the rear surface of the panel to a receiving member such as an L-shaped steel fixed to a concrete slab or a steel beam with a bolt directly or through an intermediate member (Japanese Patent Laid-Open No. 58-58). -17948, JP-A-60-10
2452).

That is, the work of fixing the panel to the frame is performed inside the building, and since the interior materials such as the inner wall are attached after that, there is a problem that the construction period is long and the work is damaged. When it is necessary to replace the panel of the part, the interior material must be removed before the replacement work, which is extremely troublesome.

On the other hand, in order to prevent rainwater and the like from entering through the gaps between the adjacent panels, as shown in the above-mentioned publications, packing materials such as packing and putty are filled in the gaps. However, this not only causes the construction period to be lengthened, but also when the sealing material is incompletely filled or deteriorates with time to cause cracks or shrinkage, rainwater enters by capillary action.

Therefore, in a curtain wall type wall structure, a so-called non-sealing method in which a drainer is provided on the panel, or packing or caulking material is arranged on the back side of the panel, or a waterproof wall is installed and the gap is not filled with a sealing material However, water drainers impair the external appearance of the wall and those that are waterproof on the back side inevitably require a special passage for discharging invading rainwater and complicate the structure.

Further, even in a wall structure using a panel mainly composed of a metal plate other than lightweight concrete, the panel is joined to the body and waterproofed by the same means as described above, and therefore, there is exactly the same problem.

[0007]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to construct a wall structure constructed by attaching a panel to a frame, and since the panel is connected to the frame on the back side, a part of it is replaced. Is extremely troublesome, the method of waterproofing the gap between the panels with a sealing material has a problem in reliability, and these are the cause of prolonging the construction period, and draining invading rainwater. There is no suitable and simple structure.

[0008]

In order to solve the above-mentioned problems, the present invention fixes a bracket having two mounting plates parallel to each other to a frame at appropriate intervals, and a bottom plate and two parallel ends of both sides of the bottom plate. A mounting rail having a side plate is continuously arranged vertically and horizontally so that the internal spaces are communicated with each other, and the side plate is placed on the mounting plate and fitted and fixed to the bracket, and a mounting frame having an insertion edge and a pressing edge is formed on the peripheral edge of the back surface. By inserting the inserted edge into the space and stacking the retaining edge on the bottom plate, the adjacent panels are fixed to the mounting rail with a gap between them, so that the panels can use the gap from the front side. The object is to provide a wall structure that can be fixed to the body, shortens the construction period, and is easy to replace.

In addition to the above, according to the present invention, a waterproof sheet is sandwiched between the bottom plate and the pressing edge, and flexible band plate-shaped sealing members having a panel gap projected to the insertion edge are overlapped with each other. Achieved the purpose of providing a wall structure that can be waterproofed for a long time and has a shortened construction period, and a gutter passage is formed in the space of the mounting rail to form a panel. The purpose of the present invention is to provide a simple structure for appropriately discharging rainwater by forming a groove passage toward the gap.

[0010]

The brackets are fixed to the skeleton in advance or at predetermined appropriate intervals when building a wall, and the mounting rails are fitted and fixed to the brackets. Next, by inserting the insertion edge into the space of the mounting rail and stacking the holding edge on the bottom plate, a gap is provided between adjacent panels, and this is fixed and removed by using the gap. From.

Further, the waterproof capacity is increased by the waterproof sheet and the seal member, and in particular, the double seal member that closes the gap is flexible and the inside of the gap is made to have an equal pressure with the atmosphere without airtightly blocking the inside and outside. Maintain and prevent rainwater from entering due to pressure difference. Furthermore, the rainwater that has entered the gap is discharged from the lowest end along the groove passage of the panel and the gutter passage of the mounting rail.

The mounting rail 21 is a long member having a substantially U-shaped end surface, and the tip ends of side plates 23, 23 projecting parallel to each other at right and left edges of the bottom plate 22 are bent inward to form an L-shaped end surface. The weir edges 24, 24 are formed. Also, the bottom plate 22
Has screw holes 25 on the center line at appropriate intervals, and has ridges 26, 26 extending in the longitudinal direction near both edges, and the side plates 23, 23 are made of long holes in the longitudinal direction corresponding to the screw holes 25. The side plates 23, 2 are provided with bolts 28 and nuts 29 inserted into the mounting holes 27 and the mounting holes 15 of the bracket 11, respectively.
3 is attached to the insides of the mounting plates 13 and 13 and the bottom plate 22 is attached to the substrate 12
The mounting rail 21 is slightly separated from the bracket 11
It is fitted and fixed in.

The displacement of the bracket 11 due to the unevenness of the surface of the body 1 or the deviation of the fixing position is absorbed by the mounting holes 15 and 27 which are long holes orthogonal to each other, and the mounting rails 21 are aligned on one plane. Can be laid.

The mounting rails 21, which are continuously arranged in a grid pattern in the vertical and horizontal directions, are connected to each other by welding or the like at both ends so that the internal spaces 30 communicate with each other.
It should be noted that the vertical mounting rail 21 is provided at the lowermost portion of the wall.
The space 30 is opened downward so that rainwater and the like flowing along the inside of the mounting rail 21 can be discharged.

The panel 31 is formed by laminating a fluororesin-based decorative film (not shown) on the front surface of the metal plate 32, and also by laminating a heat insulating material, a sound insulating material, etc., which are also not shown on the back surface, and attaching a frame 33 on the periphery of the back surface. Is provided. The mounting frame 33 is a base plate 37 fixed by bolts 35 and nuts 36 provided at appropriate intervals on the metal plate 32 with a belt-shaped waterproof sheet 34 sandwiched between the mounting frame 33 and the metal plate 32. The holding edge 39 having an end face L-shaped and further bent outward is formed at the tip of the insertion edge 38, and the insertion edge 38 has a flexible strip-shaped seal member 40. Is projected outward and is supported in a cantilever manner over the entire circumference.

The panel 31 has a retaining edge 39 with a strip-shaped waterproof sheet 51 inserted between the ridges 26, 26 by inserting the inserting edge 38 into the space 30 of the previously installed mounting rail 21. Are stacked on the bottom plate 22, and the holding edges 39 of the adjacent panels 31 are also stacked on the bottom plate 22 in the same manner.
The bolt 52, the waterproof sleeve 53, and the U-shaped pressing piece 54 on the end face are inserted into the gap 45 of 8 and the leg 5
5 and 55 are overlapped on the presser edges 39 and 39 and the presser piece 5
The bolt 52 is fixed to the mounting rail 21 by screwing the bolt 52 from the stopper hole 56 of the pressing piece 54 through the waterproof sleeve 53 into the screw hole 25 of the bottom plate 22 with the waterproof sleeve 53 sandwiched between the waterproof sheet 53 and the waterproof sheet 53. .. The seal members 40 of the adjacent panels 31 are overlapped with each other to form the gap 45.
Close up.

As described above, the outer wall of the building is constructed by fixing the panel 31 to the mounting rail 21 and arranging them on a plane with a gap 45 therebetween, and the bracket 11, the mounting rail 21, and the panel 31. Since all of them are attached from the outside of the frame 1, the construction period can be greatly shortened by installing the interior materials in parallel.

Further, the seal member 40 that closes the gap 45 by overlapping each other is flexible, and since the inside and the outside thereof are not airtightly closed, the inside pressure is always equal to atmospheric pressure. Therefore, rainwater or the like is prevented from entering due to the pressure difference. However, when the rainwater or the like enters the inside of the gap 45 due to being blown by a strong wind or the like, if the gap 45 along the lateral mounting rail 21 is located below Groove passage 4 formed by inserting edge 38 and pressing edge 39 of the upper edge of panel 31
1 to flow into the vertical mounting rail 21. Rainwater that has entered the vertical mounting rails 21 is discharged as it is or through the gutter passage 42 surrounded by the bottom plate 22, the side plates 23, and the weir edge 24 and is discharged from the lowermost end.

A waterproof sheet 51 is provided between the presser edge 39 and the bottom plate 22. If rainwater leaks from these gaps, the mounting rail 21 guides the rainwater or the like to the bottom end. To be discharged from.

Next, a corner panel 61 bent into an L shape is used for the corner portion of the building.
The attachment means to 1 is exactly the same as above.

The lowermost end of the wall is the end face L with reference to FIG.
The bracket 65 of the shape is fixed to the skeleton 1 by the bolts 67 and the nuts 68 by the same means as the bracket 11, and the side plate 72 of the L-shaped end mounting rail 71 is fixed to the mounting plate 66 by the bolts 74 and the nuts 75. This mounting rail 7
1, a holding edge 39 along the lower edge of the panel 31 and a drainer 81 are overlapped with the waterproof sheet 76 sandwiched between the bottom plate 73 facing downward.
The drain 81 has a bottom plate 73 by means of bolts 82 and nuts 83.
And the sealing member 40 was brought into contact.

In this embodiment, the outer wall is used, but the inner wall is constructed with the same structure. In this case, the seal member 4 is used.
Instead of 0, or with the seal member 40 as it is, it is preferable to fit and close the joint material for makeup in the gap 45. However, the seal member 40 is attached to the insertion edge 38 so as to be located deep in the gap 45 to make it difficult to see from the outside, and the panel 31 can be made to appear as if it is thick to give a solid feeling. ..

The adjacent panels 31 are separated by bolts 5 separately.
2, it may be fixed by the pressing piece 54, but a part of the panel 31
Adjacent panel 3 even if bolt 52 is removed to replace
Since the remaining three sides of 1 are fixed and do not move, there is no problem even if they are fixed by the common bolt 52 and the pressing piece 54 as in the illustrated embodiment.

Needless to say, the mounting rails 21 are arranged not only horizontally and vertically in accordance with the shape and size of the panel 31 but also in oblique vertical and horizontal directions, or of a suitable size having, for example, intersections. The mesh-shaped members may be sequentially connected and fixed to the bracket 11.

Further, the bracket 11 can be fixed to the skeleton 1 in advance, and it is convenient to weld it especially when the skeleton 1 is a steel frame.

[0028]

According to the present invention, mounting rails that are continuous in the vertical and horizontal directions are fixed to a skeleton by brackets, and the peripheral edge portions of the panels of the mounting rails are fitted and fixed, and a gap between adjacent panels is used. Since it can be fixed and removed from the front side, it is possible to proceed with the construction on the opposite side of the skeleton in parallel, which not only greatly shortens the construction period, but also replaces some panels or all panels from the front side. It can be performed and the work is easy.

Further, since waterproofing of the gap is performed by stacking flexible strip-shaped seal members provided on the panel, it is not necessary to fill the seal material after the panel is installed, which not only helps shorten the construction period but also seals the seal. The inside and outside of the member are maintained at the same pressure, and rainwater does not enter due to the pressure difference. Further, even if it should enter, it can be properly discharged by being guided to the lowermost end by the groove passage toward the gap between the panels and the gutter passage toward the space where the panel of the mounting rail is fitted.
