Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for renovating the exterior of an existing building.

Existing buildings have exterior materials such as tiles and mortar layers attached to the outer walls of the building blocks, and as time passes, the exterior materials may peel off or cracks may occur in the mortar layer. This will cause damage.

For this reason, the exterior of the existing building becomes unsightly, and rainwater and the like can enter the building frame, which is undesirable.

Therefore, as shown in Japanese Patent Publication No. 56-51265, for example, a plurality of supporting metal fittings are installed at intervals in the vertical direction on the outer wall of the existing building frame, and a mullion for assembling a curtain wall is installed between the supporting metal fittings. Renovation equipment is known in which the outer walls of the building structure are covered with a new curtain wall.

With this renovation device, it is possible to cover the exterior of a damaged outer wall of a building frame with a new curtain wall to improve its appearance and to prevent rainwater from penetrating into the outer wall of a building frame.

However, in the case of the above-mentioned renovation equipment, the supporting hardware is attached to the outer wall of the building frame, so the installation position of the mullion is significantly farther away than the outer wall of the building frame, and the amount of protrusion of the new curtain wall from the outer wall of the existing building frame is reduced. (In other words, the amount of overhang of the newly renovated curtain wall is large), which is not desirable because the construction area becomes large or it overhangs the neighboring land.

The present invention was made in view of the above circumstances, and its purpose is to easily renovate the exterior of an existing building into a new curtain wall, and to reduce the amount of protrusion of the renovated new curtain wall from the outer wall of the existing building frame. To provide an exterior renovation device for an existing building that can be made smaller.

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 is a partial schematic vertical cross-sectional view of the existing building.
The frame A includes a floor slab 1 and an outer wall 2. An opening 3 is formed between the floor slabs 1 in the outer wall 2, and the outer wall side portion of the frame A has an inverted T-shaped cross section due to the floor slab 1 and the outer wall 2. It's summery.

An existing sash frame 4 is attached to each opening 3, and a shoji 5 is provided on the existing sash frame 4.

To renovate the exterior of the existing building, first measure the dimensions of the existing sash frame 4 and frame A, and then remove the shoji 5.

As shown in FIG. 2, upper connecting pieces (fasteners) are attached to the upper frame 4a and lower frame 4b of the existing sash frame 4.
6. Fix the lower connecting pieces 7 (fasteners) respectively, and attach the upper and lower brackets 8, 8' to the upper and lower connecting pieces 6, 7.
are provided respectively.

After that, the first, second, and third mullions 9 ₁ , 9 ₂ , and 9 ₃ are attached to the upper and lower brackets 8 and 8', respectively, and the lower end of the first mullion 9 ₁ and the second mullion 9 2 are attached to the upper and lower brackets 8 and 8 _' . The first mullion 91 and the second mullion 92 are connected to the first mullion lower end surface _91a and _the second mullion by fitting the sleeve ₁₀ over the upper end portions.
The mulloid upper end surface 9 ₂ b is connected so as to be spaced apart from each other, and the second
A sleeve 10 is fitted over the lower end of the mullion 9 ₂ and the upper end of the third mullion 9 ₃ to connect the second mullion 9 ₂ and the third mullion 9 ₃ to the second mullion lower end surface 9. The mullion 9 is attached to the existing sash frame 4 via the brackets 8, 8' by connecting the mullion _2a and the third mullion upper end face _93b so as to be separated from each other.

Then, as shown in FIG. 3, the blinds 11 are attached across the mullions to form square frame sections 12, and panel members 13 are attached to each square frame section 12 to form a curtain wall. The outer wall 2 of the frame is covered with a wall, and fittings 13' such as a revolving window are attached to the rectangular frame 12' facing the opening 3 of the frame.

In Fig. 3, 14 is an upper cover material (kasagi) installed across the outer wall upper part 2' and the uppermost open wall 11', and 15 is the upper cover material (kasagi) installed between the lowermost open wall 11'' and the lower outer wall 2''. This is the lower cover material that was installed across.

Since the exterior of the existing building is renovated by covering the outer frame wall 2 of the existing building with a curtain wall in the manner described above, the refurbishment work becomes easy.

In addition, the mullions 9 are the upper and lower frames 4a of the existing sash frame 4,
Since it is attached to the upper and lower connecting pieces 6, 7 attached to the frame 4b via the brackets 8, 8', the distance between the mullion 9 and the outer wall 2 of the frame is shortened, and the mounting position of the mullion 9 is moved closer to the outer wall 2 of the frame. It can be the location.

Therefore, the amount of protrusion of the curtain wall from the outer wall of the existing building frame can be reduced, and the construction area can be reduced.

Next, a specific example will be explained with reference to FIGS. 4 and 5.

First, an upward U-shaped base 21 with bolts 20 welded and fixed to the upper frame 4a is welded and fixed, and the horizontal piece 6a of the upper connecting piece 6 is brought into contact with this base 21, and the long hole 22 in the out-of-plane direction is made into contact with the base 21. The upper connecting piece 6 is attached to the upper frame 4a via the base 21 by loosely fitting it into the bolt 20 and screwing the nut 23 onto the bolt 20. Because of this, the mounting position can be adjusted in the out-of-plane direction using the elongated hole 22.

On the other hand, since the lower frame 4b has an indoor side rising piece 4'b and a horizontal piece 4''b, and the lower connecting piece 7 cannot be installed horizontally, a height adjustment piece 24 having a substantially U-shaped cross section is attached to the horizontal piece 4''b. are fixed by welding, and the mounting base 25 is mounted astride this height adjustment piece 24 and the rising piece 4'b.
Weld and fix it in a horizontal position.

Then, the lower connecting piece 7 is attached by loosely fitting the out-of-plane elongated hole 27 formed in the horizontal piece 7a of the lower connecting piece 7 onto the bolt 26 welded and fixed to the mounting base 25, and screwing the nut 28. It is fixed to the base 25.
Because of this, the lower connecting piece 7 can be mounted horizontally, and the mounting position can be adjusted in an out-of-plane direction.

Thereafter, the upper and lower brackets 8 and 8' are attached to the vertically bent pieces 6b and 7b of the upper and lower connecting pieces 6 and 7 with bolts 29 and nuts 30, respectively.

2, 32 are drilled, the base vertical wall 8a abuts the bent pieces 6b, 7b, and the bolt 29 is inserted into the elongated hole 32,
31 and screw the nut 30 on.

Because of this, the mounting position of the brackets 8, 8' can be adjusted in the in-plane direction in the lateral and vertical directions by the elongated holes 32 and 31.

After this, the mullions 9 are attached to the upper and lower brackets 8,8.

That is, the mullion 9 includes a front vertical wall 9a, a connecting wall 9b, and a U-shaped base vertical wall 9c, and the base vertical wall 9c is fitted into the front vertical wall 8c of the bracket 8 from above and below, and the screw It is fixed at 33.

Therefore, the mullion 9 can be stably mounted, and adjustments of the bracket 8 and the mullion 9 can be performed from within the frame.

Then, the blind 11 is attached, the panel member 13 and fittings 13' are attached, and the frame opening 3 is covered with a cover. That is, the upper cover 40 covers the upper frame 4a and the blind 11, the lower cover 41 covers the lower frame 4b and the blind 11, and the vertical cover 42 covers the vertical frame 4c and the mullion 9. Once installed, the existing sash frame 4 and body opening 3 are covered with covers 40, 41, 42, and 42. Note that a sealing material 45 is installed between the vertical cover 42 and the vertical frame 44 attached to the mullion 9.

Therefore, the sealing performance of the newly installed curtain wall is good, and since it covers the existing sash frame 4, the appearance is good.

In addition, the bracket 8 is attached to the mullion 9 in advance,
The bracket 8 may be attached to the upper and lower connecting pieces 6 and 7.
