Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for attaching exterior wall panels.

[Prior art]

Conventionally, it has been widely adopted to attach external wall panels of buildings, etc. to mullions. A sealing material such as caulking is embedded in the joints between these outer wall panels to stop water after the outer wall panels are fixed. This type of sealing work was a troublesome and dangerous work, requiring scaffolding to be erected outside the room.

In order to solve this problem, it is possible to fix sealing material in advance at the joints of the exterior wall panels and assemble the exterior wall panels from the outdoor side, but it is difficult to install the exterior wall panels. Water-stopping performance cannot be maintained unless strict precision is maintained.

[Purpose of the invention]

This invention was made in order to eliminate the above-mentioned drawbacks, and provides an installation method for external wall panels that can be installed without the need for external scaffolding and that can ensure sufficient water-stopping performance. The purpose is to

[Structure of the invention]

The method for installing exterior wall panels according to this invention is as follows:
On the outside of the structure's frame, mullions with vertically continuous sealing material fixed along the outer wall panel surface are fixedly erected at predetermined intervals to the structure frame, and water-stopping seals are installed around the four circumferences of the outer wall panel body. Attach the rotating edges, fix sealing material to the upper or lower rotating edges in advance, and make the rotating edges on both the left and right sides of the outer wall panel contact the sealing material that is continuously fixed in the vertical direction of the mullion. Further, by stacking the outer wall panels one after another on the fixed outer wall panels, the horizontal sealing material fixed to the upper or lower circumferential edge is crimped, and the horizontal sealing material is made to intersect with the vertical sealing material provided on the mullion. Fix the exterior wall panels in contact with the panels, and install the water stop material for the primary seal from above between the left and right edges of the adjacent exterior wall panels.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

In the figure, reference numeral 1 denotes mullions provided at predetermined intervals at predetermined positions on the outside of the structural frame of a building, and a sealing material 2 is fixed to one side in advance in a factory or the like. In the embodiment, a panel mounting member 3 having a U-shaped cross section and reinforcing pieces 31, 31 at both ends is fixed to one side of the mullion, and a sealing material 2 is further applied to the surface of the panel mounting member 3.
is fixed. In the panel mounting member 3, rectangular locking holes 32 are formed near the reinforcing pieces 31, 31, respectively, and the locking holes 32, 32 are formed at a plurality of locations at appropriate intervals in the longitudinal direction.

The sealing material 2 is made of an elastic member such as rubber, and protrusions 21 and 22 are formed on the surface thereof over the entire length in the longitudinal direction. Seal material 2
A first protruding piece 21 and a second protruding piece 22 are formed symmetrically to the left and right from the center in the width direction. 1st
The protrusion 21 has a tongue shape, and the second protrusion 22 has a cylindrical shape.

The mullion 1 configured as described above is vertically arranged with the sealing material 2 facing the outdoor side. An outer wall panel 4 is fixed to this mullion 1.

The outer wall panel main body 4 can be a panel made of a material such as metal or concrete. In the embodiment, a steel plate 42 is used on the outer surface, mullion-shaped connecting fittings 41 are fixed to the inside of the four corners, and a heat insulating material is stretched inside.

In addition, metal plates such as aluminum and stainless steel, lightweight concrete plates, precast concrete plates, etc. can be used as the exterior wall panel body 4. The outer wall panel A is constructed by fixing water-stopping edges 5, 6, 7, and 8 made of metal or non-metal to the upper, lower, left, and right peripheries of the outer wall panel main body 4.

The upper rotating edge 5 fixed to the upper end of the outer wall panel main body 4 has a rising piece 51 on the indoor side;
A horizontal piece 52 is formed at the upper end thereof over the entire length in the longitudinal direction. An interior material holding edge 53 is further provided on the indoor side of the horizontal portion 52 and extends upward and downward.

The lower circumferential edge 6 fixed to the lower end of the exterior wall panel main body 4 has a hanging piece 61 formed over the entire length on the outdoor side, and a vertical water return 62 on the indoor side and a horizontal piece 63 extending toward the indoor side over the entire length in the longitudinal direction. It has been formed over the years. A sealing material 9 having elasticity such as rubber is pasted over the entire length of the fixing part having an L-shaped cross section formed by the water stop piece 62 and the horizontal piece 63, and both left and right ends of the sealing material 9 are It protrudes to the side edges of the left and right edges 7 and 8.

The rotating edges 7 and 8 fixed to the left and right ends of the outer wall panel main body 4 are two parallel protrusions 71 and 7 on the indoor side.
2, 81, 82 are formed over the entire length, and at the indoor end there is a contact piece 73 parallel to the indoor surface of the panel 4,
83 protrudes over the entire length in the longitudinal direction. The ends of the contact pieces 73, 83 on the opposite side from the panel 4 are bent toward the outdoor side and have a hook-like cross section.

A locking member 1 is provided on the indoor surface of the outer wall panel main body 4.
0 is fixed. The locking member 10 has a locking slit 11 formed upward from the lower end. The protruding portion of the locking member 10 corresponds to the locking hole 32 of the panel mounting member 3.

When installing the exterior wall panel A constructed as described above, the exterior wall panel A is positioned from the indoor side of the building to the outdoor side of the mullion 1. Insert the locking member 10 of the outer wall panel A into the locking hole 32 of the panel mounting member 3 from the outdoor side, and insert the locking hole 32 into the locking slit 11.
Insert the lower part of the panel and temporarily secure the outer wall panel A.
If the outer wall panel A is temporarily fixed in this way, positioning becomes easy and support to prevent falling becomes extremely easy.

Next, a bolt 13 is inserted through the reinforcing member 12 having a U-shaped cross section and the surface of the panel mounting member 3, which is similarly fixed to the indoor surface of the outer wall panel A, and the bolt 13 is inserted into the nut 14 located inside the reinforcing member 12. Screw them together to fix the exterior wall panel A.

Left and right edges 7 of adjacent left and right exterior wall panels A,
A water stop material 15 for primary sealing is inserted between the spaces 8 and 8 from above and installed. The water stop material 15 is made of an elastic material such as rubber, and has a substantially C-shaped cross section at the middle part in the width direction, and water stop pieces 16, 16 are formed laterally from the two ends. has been done. The water stop material 15 configured in this manner is inserted into the vertical space formed by the protrusions 71 and 72 and the protrusions 81 and 82.

The outer wall panel A is stacked and fixed on the already fixed outer wall panel A, and a sealing material 9 is interposed between the upper and lower outer wall panels A. That is, exterior wall panel A
Since the sealant 9 is already fixed to the outer wall panel A, when the outer wall panel A is placed on the upper circumferential edge 5 of the lower outer wall panel A, the sealant 9 comes into contact with the upper surface of the horizontal portion 52 of the upper circumferential edge 5. Do it like this. Seal material 9
is crushed by the weight of the panel 4, and the close contact between the upper and lower panels 4 becomes complete. It protrudes to the side edges of the left and right edges 7 and 8 of the sealing material 9, and the mullion 1
The indoor side surfaces of the horizontal sealing material 9 are brought into contact with the projecting pieces 21 and 22 of the vertical sealing material 2 so as to be perpendicularly overlapped with each other. Therefore, even if there is some error in installation accuracy and the gap between the left and right exterior wall panels A becomes wider or narrower, the sealant 2 of the mullion 1 will still come into contact with the sealant 9 of the exterior wall panel 4, so water will be stopped. The effect never decreases.

Seal material 9 protruding from both left and right sides of exterior wall panel A
Protective members 18 made of hard rubber are fitted into the hook-shaped contact pieces 73 and 83 above and below the sealing material 9 to prevent abnormal deformation of the sealing material. Moreover, the interior material holding edge 53 on the outdoor side of the upper rotating edge 5 is connected to the sealing material 2 of the mullion 1 and the contact pieces 73, 83 of the left and right rotating edges 7, 8.
Make a notch so that it does not interfere with contact.

In order to hide the bolt 13 and the locking member 10, a decorative material 17 made of synthetic resin or the like and having a substantially U-shaped cross section is fitted along the reinforcing piece 31 of the panel mounting member 3 and the outer surface of the mullion 1. Mullions of different sizes 1'
In this case, the size of the decorative material 17 may be changed accordingly.

〔Effect of the invention〕

Since the present invention has the above configuration, the following effects can be obtained.

Because the sealant is fixed to the mullions and exterior wall panels in advance at a factory, etc., installation work can be done from the indoor side, and it can be installed adjacent to other buildings without the need for scaffolding outside. Installation work can be done easily and safely.

Since the horizontal sealing material between the upper and lower panels was overlapped and abutted from the outdoor side against the vertical sealing material fixed to the mullion, even if there was some error in the installation accuracy of the panels, the vertical sealing material would still be applied. Since the horizontal sealing material and the horizontal sealing material abut perpendicularly to each other, the water-stopping effect is not reduced.

In addition, by stacking multiple tiers of exterior wall panels and then inserting and fixing water-stopping material for the primary seal from the top, it is possible to form a double structure that prevents rainwater from entering even if rainwater sprays from the outside. .
