Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a curtain wall.

[Conventional technology]

As a conventional curtain wall, for example,
There is one shown in the figure.

This curtain wall consists of mullions 2 attached at regular intervals to a beam 1, which is the frame, and horizontal frames 3 attached with screws via brackets between each mullion 2.
and a panel 4 made of glass, decorative board, etc. attached to a lattice-like wall frame made up of the horizontal frame 3 and the mullions 2 via ribs.

Therefore, the construction was carried out in the following steps.

(1) First, as shown in Fig. 9A, a plurality of mullions 2 are fixed at regular intervals to the beam 1, which is the frame, via brackets. At that time, the inside and outside directions of each mullion 2,
Determine the opening direction and vertical position before fixing.

(2) Next, install the horizontal frames 3 between each mullion 2 one by one at regular intervals using screws through the brackets of each mullion 2, as shown in Fig. 8 (b). A wall frame consisting of a vertical frame 2 and a horizontal frame 3 is constructed.

(3) After that, a panel 4 such as glass or a decorative board is attached to this frame via a rim or the like.

[Problem that the invention attempts to solve]

However, this curtain wall had the following problems.

(1) Since we are planning to install the mullion 2 to the beam 1 in advance and then attach the horizontal frame 3, the installation screws for the horizontal frame 3 are essential, and certain Clearance required. As a result, the screws are exposed to the outside, and a gap is created between the mullions 2 and the horizontal frame 3, through which the brackets are visible, making it impossible to obtain a curtain wall with good appearance.

Of course, if you make a notch in the horizontal frame in advance and fit it into the mullion bracket from this part to prevent it from coming out, you can avoid using screws, but the notch will need to be processed, and the horizontal frame Since the notch is visible from the outside, the problem of appearance still cannot be solved.

(2) Furthermore, as mentioned above, since the construction method must be used to attach the mullions 2 to the beams 1 in advance, it is difficult to accurately determine the relative positional relationship of each mullion 2, which makes construction difficult. In some cases, it was not possible to obtain a curtain wall with high precision.

(3) Since the horizontal frame 3 is attached to the bracket of the mullion 2 with screws, and the bracket is also attached to the mullion 2 with screws, the attachment strength of the horizontal frame 3 to the mullion 2 is relatively weak.

This invention was made to solve these conventional problems, and its purpose is to provide a curtain wall that looks good, is easy to install, has good precision, and has high installation strength. be.

[Means for solving problems]

The curtain wall according to this invention consists of a cylindrical mullion with bolts, insertion holes, and horizontal frame fitting protrusions coaxially provided on the left and right sides at regular intervals in the length direction, and a cylindrical mullion inside the mullion. A connecting member that is inserted to connect the mullions in the length direction, a bracket that attaches the mullions to the frame, and a cylindrical horizontal frame and a horizontal frame that fit into the horizontal frame fitting protrusion of the mullion at the end. It is equipped with a wall frame consisting of bolts and nuts that are inserted into the bolt insertion holes of the mullion and bolts to tighten the horizontal frame and the mullion together.

In addition, 21 is the decorative board covered by the corner mullion _H1 (Fig. 2), and 22 is the concrete slab (Fig. 4).
It is.

Next, an example of the construction method of this curtain wall will be explained in order of steps with reference to FIGS. 1 to 7.

6 and 7 schematically show the procedure for constructing the curtain wall shown in FIG. 1, as in the same figure.

In the first step, as shown in Figure 6A, the first mullion is
The first column of mullions is attached to beam B by connecting _H1 with connecting member 14 and attaching bracket b to beam B. At this time, the positions of the mullions in the first row in the inner and outer directions, the opening direction, and the upper and lower directions are accurately determined while varying the relative positions of the bolt holes of the bracket b.

In the second step, as shown in FIG. 6A, one end of the first horizontal frame Y 1 is fitted into the horizontal frame fitting protrusion _{b 1} provided in advance on the side surface of the fixed mullion in the first row.
In this way, add the first horizontal frame to the mullion in the first column.
Install the required number of _Y1 .

In the third step, as shown in Figure 6B, the second mullion is
H ₂ are connected by the connecting member 14, and the horizontal frame fitting protrusion b ₂ is fitted to the other end of the first horizontal frame Y ₁ , and a second mullion H ₂ is connected to the other end surface of the horizontal frame Y ₁ . Press the sides together and in this state attach the second mullion _H2 to beam B with bracket b. In this way, the second row of mullions is attached to beam B. At this time, the positions of the mullions in the second row in the inner and outer directions, the frontage direction, and the vertical direction are determined in the same manner as in the first step.

Then, as shown in Figure 7, the first horizontal frame _Y1 and the mullions are connected so that there is no gap between the mullions in the first row, the first horizontal frame _Y1 , and the mullions in the second row. Insert bolts and nuts N into the bolt insertion holes of the first mullion H ₁ and the second mullion H ₂ that are connected to this, and then insert the bolts and nuts N into the first horizontal frame Y ₁ and both the first and second mullions H. ₁ and _H2 together.

In the fourth step, the second and third steps are repeated to create a second horizontal frame Y ₂ and a second horizontal frame in the second row of mullions.
Install the third row of mullions on Y ₂ ... and so on, then install the nth row.
Attach up to the mullions in the rows.

In the fifth step, a ridge 15 is attached to the wall frame consisting of the mullions from the first to nth rows and the first to n-1th horizontal frames Y ₁ to _{Y o-1} attached to these mullions. Attach glass G through it.

As described above, according to this embodiment, the mullions H ₁ , H ₂ ... attached to the beam B, and the mullions H ₁ , H ₂
Cylindrical horizontal frames Y ₁ , Y 2 ... that are fitted between the horizontal frame fitting protrusions b 1 , b ₂ ... provided on ... and installed between the respective mullions _{H 1 , H 2 ...} , A wall frame is constructed by the bolts and nuts that are inserted into the bolt insertion holes of the horizontal frames Y _{1 ,} Y _{2 .} . . and the mullions H 1 , H ₂ . By doing so, the following effects can be obtained.

(1) If the first row of mullions H ₁ is accurately positioned and attached to the frame, the second row of mullions H ₂
While checking the positional relationship with the second horizontal frame Y ₂ ,
The mullions H ₂ in the third row can be attached one after another while checking the relationship with the third horizontal frame Y ₃ , so positioning of each mullion H ₁ , H ₂ . . . is facilitated. Therefore, it is possible to obtain a curtain wall that is easy to construct and has high precision.

(2) First row mullion H ₁ , first horizontal frame Y ₁ , second mullion H ₂ , second horizontal frame Y ₂ ... Tighten the mullions and horizontal frames in this manner. The mullions H ₁ , H _{2 .} . . and the horizontal frame Y ₁ , can be installed alternately.
There is no gap between Y ₂ and... Therefore,
As in the past, mullions H ₁ , H ₂ ... and horizontal frames Y ₁ , Y ₂
There is no longer a possibility that a gap will be created between the horizontal frame fitting protrusions b ₁ , b ₂ , etc., resulting in an unsightly appearance.

(3) Since the mullions H ₁ , H ₂ ... and the horizontal frames Y ₁ , Y ₂ ... are tightened together with bolts and nuts N, the assembly strength of the wall frame is increased, and the mullion
There is no possibility that a gap will be created after the fact between H ₁ , H ₂ . . . and the horizontal frames Y ₁ , Y ₂ .

[Effect of idea]

As explained above, according to this invention, the mullions and the horizontal frames can be assembled alternately, and the mullions and the horizontal frames can be joined together with bolts and nuts, so it looks good and is easy to construct. A curtain wall with good precision and high assembly strength can be obtained.
