Description

Description: TECHNICAL FIELD The present invention relates to a method of attaching a cuboid in a cuboid curtain wall to a building frame.

[Conventional technology]

A cubic curtain wall is one in which face materials such as glass and windows are attached between adjacent cubics in the in-plane left-right direction attached to the building frame, and the cubic is inclined in the out-of-plane direction.
If the position in the out-of-plane direction shifts, the face material becomes slanted in the out-of-plane direction, or the position shifts, resulting in a surface misalignment, and the vertical tilts in the in-plane direction, or the position shifts. If this happens, the cuboids that are adjacent to each other in the horizontal direction in the plane may not be parallel and the face material may not be attached correctly.

That is, it is necessary to position the cuboid in the out-of-plane direction and the in-plane direction and mount it so as to be vertical in the out-of-plane direction and the in-plane direction.

For this reason, conventionally, the water system was run vertically along the building frame,
They are arranged horizontally, and the verticals are positioned one by one with respect to the water system and are mounted vertically.

[Problems to be Solved by the Invention]

It is not possible to make the vertical one length that fits the entire height of the building frame, and since it is installed continuously in the vertical direction as a predetermined length, the number of verticals becomes large, and in this way many The work of positioning the verticals one by one and installing them vertically is not only very troublesome, but also takes a long time and the construction time becomes long.

Therefore, it is an object of the present invention to provide a method of attaching a cuboid that can be easily and accurately attached in a short time.

[Means and Actions for Solving the Problems]

A pair of horizontal in-plane water threads 3 and 3 are positioned vertically in the in-plane and out-of-plane directions on the building frame, and a pair of horizontal 10 , 10 are positioned in the in-plane direction and the out-of-plane direction, and are vertically attached to the building frame, and the lower part of the next azimuth 10 is connected to the upper part of each of the uprights 10 and 10 via a joint sleeve 15. Each cubic
The lower part of 10 is positioned in the in-plane direction and the out-of-plane direction with reference to the upper part of the pair of uprights 10 and 10 by the joint sleeve 15, and between the inner surfaces of the upper parts of the next uprights 10 and 10, both end faces 31 are formed. The size of the next stand 1 is set by disposing the stand set jig 30 in which the dimension between them is the same as the mounting distance between the pair of stands 10.
After positioning the upper part of 0 and 10 in the in-plane direction with the pair of uprights 10 and 10 as a reference, the distance between the upright setting jig 30 and the water thread 3 is adjusted and the upright 10 This is a mounting method in which the upper part of 10, 10 is positioned in the out-of-plane direction with the water thread 3 as a reference and is connected to the building frame with a fastener. If it is positioned in the inward and out-of-plane directions and installed vertically, the next pair of uprights 10 and 10 can be positioned in the in-plane and out-of-plane directions at the same time by using the upright set jig 30. Can be attached to the building frame.

〔Example〕

As shown in FIG. 1 and FIG. 2, PC boards 2 are attached to the front surface of each slab 1 constituting the building body A with fasteners (not shown) at intervals in the in-plane left-right direction and are adjacent in the in-plane left-right direction. Install a vertical curtain wall between the PC boards 2 and 2.

Then, between the PC plates 2 and 2 adjacent to each other in the in-plane left-right direction, a pair of in-plane left-right water threads 3, 3 are positioned vertically in the in-plane direction and the out-of-plane direction.

As shown in FIG. 1, the in-plane left and right uprights 10 and 10 are formed in the in-plane direction and across the lowermost slab 1 and the second-stage slab 1 with the pair of water threads 3, 3 as a reference. , Position out of plane and mount vertically.

At this time, the lower parts of the pair of uprights 10 and 10 may be positioned and attached, and then the upper part may be positioned by the upright set jig described later, or the upper parts may be previously positioned and attached.

The vertical 10 is a vertical plate facing out of plane as shown in FIG.
A plurality of protruding pieces 12 are integrally formed on the inner side of 11 and a groove groove 13 is integrally formed on the inner side of the outer side, and the inner shape of the upright 10 is uneven and the outer side of the vertical plate 11 is formed. A vertical seal material 14 is attached to the outdoor side of the, and a joint sleeve 15 is bolted to the concave groove 13 together with the vertical side fastener 16.
The joint sleeve 15 is attached at 17 and projects upward from the upper end of the upright 10.

A step portion 2a is formed on the PC plate 2 toward the indoor side, and a vertical seal member 14 of a cuboid 10 is pressure-bonded to the step portion 2a.

Next, on the upper part of the pair of uprights 10, 10, the next pair of uprights 1
As shown in Fig. 4, connect the lower part of 0 and 10 to the joint sleeve.
The recessed groove 13 is connected to the protruding portion 15 so that the groove 13 is closely fitted.

Accordingly, the lower parts of the next pair of uprights 10, 10 are positioned by the joint sleeve 15 in the in-plane direction and the out-of-plane direction.

After that, as shown in FIGS. 5 and 6, both end faces 31, 31 of the plate-shaped upright setting jig 30 are connected to the pair of uprights 10, 10.
The pair of uprights 10 and 10 are made parallel to each other by abutting between the inner surfaces of the upper part of 10 and defining the dimension between the upsides of the pair of uprights 10 and 10 to a predetermined value.

That is, the end face 31 of the vertical setting jig 30 has a stepped shape so as to contact each inward piece 12 of the vertical 10, and both end faces 31, 3
The dimension between 1 is the same as the mounting distance between the pair of uprights 10, 10 and the width L ₁ is the same as the out-of-plane length L _{2 of the} upright 10.

At the same time, the vertical side fastener 16 and the building body side fastener 20 temporarily fixed to the slab 1 are temporarily fixed with bolts 21.

In this state, as shown in FIG. 6, the finger 40 is brought into contact with the end face 32 of the vertical setting jig 30 to adjust the protrusion width in the out-of-plane direction with respect to the water thread 3 so that the upper portion of the vertical 10 is covered. Position outward and then tighten the bolts to connect.

In other words, the horizontal piece 22 of the building body side fastener 20 is connected to the board 23 by the bolt 24, and can be adjusted in the out-of-plane direction along the elongated hole 25, and the vertical piece 26 has the out-of-plane elongated hole 27. It is connected to the vertical side fastener 16 with the inserted bolt 21, and the vertical direction 10 is temporarily fixed to the slab 1 with the bolts 21 and 24 loosened,
After positioning in the in-plane direction with the vertical set jig 30, tighten the bolts 21 tightly to firmly connect the vertical side fastener 16 and the building body side fastener 20, and after positioning in the out-of-plane direction with the metal fitting 40, tighten the bolt 24. Refasten and tighten on the building side
Tightly connect 20 to slab 1.

In the same manner, attach the cubes in order.

〔The invention's effect〕

First, if a pair of uprights 10 and 10 to be attached to the building frame are positioned vertically in the in-plane and out-of-plane directions, the next pair of uprights 10 and 10 uses the upright set jig 30. By that 2
At the same time, it can be positioned in the in-plane direction and the out-of-plane direction and attached to the building frame.

Therefore, the vertical 10 can be easily and accurately attached in a short time.
