Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a curtain wall installation method and a multiple curtain wall used in the method.

As shown in Figure 7, the conventional curtain wall installation method involves hoisting the curtain wall a to the outside, moving it toward the building (in the direction of the arrow in the figure), and fixing it with anchor poles b, etc. In addition, since the curtain wall a is suspended by a wire C or the like, it is difficult to prevent the curtain wall a from swinging during hanging, which may cause damage to the curtain wall a. Furthermore, in general, the overlapping parts of curtain walls a are made to have a higher inner side and are polymerized in order to provide a waterproof effect. Therefore, in order to remove a particular curtain wall a, it is necessary to remove the upper curtain wall a in sequence. must,
It took a lot of time and effort.

Furthermore, as shown in Figure 2, if a design panel d or the like is installed on the outside, an external scaffold e is required when attaching or removing it, and this work may be difficult in places where only a narrow work space can be secured. It was subject to restrictions.

There were also various problems with the single-wall curtain wall itself.

In other words, conventional curtain walls handle various functions such as design, external force transmission, waterproofing, etc. with a single wall structure.
There was a problem with the degree of freedom.

In addition, the joint waterproofing part (for example, f in Figure 1), which is made of sealant, packing material, etc., is easily deteriorated because it is directly exposed to wind and rain, and its waterproof performance is easily influenced by quality and construction management. It was undeniable.

Some panels covered the concrete wall with another panel to block sunlight and reduce the heat load, increasing the insulation and waterproofing effects by so-called double walls, but in terms of thermal performance, it was possible to freely adjust the thermal resistance of the outer wall. They were not able to make any changes, and they were not necessarily satisfied with the results.

This invention eliminates the aforementioned problems found in the existing curtain wall installation methods, and makes it possible to install the curtain wall entirely from the building side without requiring external scaffolding when installing the curtain wall. A curtain wall that does not interfere with installation even if there is an external scaffolding, and can be replaced at any time.It is also a curtain wall that dramatically improves the efficiency and construction accuracy of each work even without hanging or outside work space. At the same time, we provide a multilayer curtain wall that is optimal for the installation method of the curtain wall and separates the requirements that the external wall should have and the requirements that should be added into the component parts, which are not found in existing curtain walls. The purpose is to provide

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

In Fig. 3 (in the figure, the direction of the arrow indicates the outside of the building), 1 is a base steel frame whose cross section is roughly shaped, and 2.2' is a cross section fixed to the recesses on both sides of the base steel frame 1. This is an L-shaped guide rail, and a groove-shaped guide portion 3 is formed by both of them. The base steel frame 1 has notches 1b bored at regular intervals in the longitudinal direction of both ends of the outer panel 1a, which is the outside of the building.
On the other hand, through holes 2a and 2 for set bolts are also provided in the guide rails 2 and 2' at the same intervals so as to correspond to the notches 1b, respectively.
'a, through-holes 2b, 2'b for adjustment bolts, and through-holes 2C12'C for horizontal support members are drilled slightly below these, respectively. The base steel frames 1 constructed in this manner are provided at appropriate locations on the outer periphery of the building at equal intervals. Next, in Fig. q, 4 is a substantially rectangular double curtain wall, which is composed of an outer panel 4a, an inner panel 4b, and a connecting material 4C that joins the two.The outer panel 4a is slightly larger than the inner panel 4b. Further, there are an appropriate number of projections 4d at appropriate locations on both ends of the inner panel 4b, and a through hole 4e for a set bolt is formed in each of the projections 4d.

To install this double curtain wall 4t, first, the horizontal support member that receives the inner panel 4b and supports the load of the double curtain wall 4 including the outer panel 4a is passed to the mutually opposing guide parts 3. In this embodiment, as shown in the figure, a through hole 5 is formed in a horizontal support member 5 having an oval-shaped longitudinal section.
a and horizontal support member through holes 2C12'C bored in the guide rails 2 and 2', respectively, were fixed with bolts 6. Thereafter, the double curtain wall 4 is suspended by a wire rope 7 as shown in the figure, and the projections 4d are placed in the opposing guide portions 3 and gently slid down.

Next, as shown in FIG. 5, screw the adjustment bolt 8 into the adjustment bolt through holes 2b and 21b, and
When the adjustment is completed, insert the set bolt 9 into the set bolt through hole 4e drilled in the protrusion 4d and the set bolt through holes 2a and 2'a drilled in the guide rail 2.2I. , fix the double curtain wall 4.

As described above, the horizontal support members 5 are fixed one after another, and the double curtain walls 4 are dropped onto them and stacked in the same manner. That is, each double curtain wall 4 is independently supported by the horizontal support member 5. By carrying out the above-mentioned installation work, the wall configuration of the building using the double curtain wall 4 is completed.

Further, in order to remove any double curtain wall 4 at a later date, the following procedure may be performed.

FIG. 7 is a view from the outside of the building. A removal hole 4f is drilled in the protrusion 4d on the inner panel 4b of the double curtain wall 4, and the removal bolt 10 is inserted into the hole and pulled outward. .

In this way, the projection 4d can pass through the notch 1b without any obstruction and the double curtain wall 4 can be pulled out, and all that is left to do is to suspend it with the appropriate wire 11 and remove it. In this case, it is necessary to remove the set bolts 9 in advance, but as described above, each double curtain wall 4 is supported independently by the horizontal support member 5, so each double curtain wall 4 You can remove any one piece at any time.

As described above, the curtain wall installation method according to the present invention allows installation and removal of the curtain wall (the double curtain wall 4 in the above embodiment) extremely quickly and easily. Furthermore, during installation, even if there is some oscillation when the double curtain wall 4 is suspended by the wire lobes 7, the oscillation will naturally subside once the protrusion 4d is placed in the guide part 3, and the rest will remain as it is. Because all you have to do is lower it down, there is very little damage to the curtain wall compared to conventional curtain wall installation methods. Furthermore, each curtain wall (double curtain wall 4) is independently supported and fixed,
Since there is no polymerized part like in the past, it is possible to remove and replace any one piece. Moreover, each of these operations does not particularly require external scaffolding, and each of the above operations can be performed satisfactorily even within the narrow space of a building. Furthermore, according to the above-mentioned embodiment, each outer panel 4a can be moved in and out by simply adjusting the adjustment bolts 8, which is extremely simple.
And fine adjustment is possible.

Waterproofing treatment can also be carried out easily and reliably.

As shown in Figures 1 to 10, a bank 4g is provided in the longitudinal direction of the back surface of each inner panel 4b, and a notch 12a is provided.
A waterproof board 12 having a
2. A waterproof surface can be constructed by filling a packing material 13 between the inner panel 4b and the guide rail 2.2'. That is, according to the present invention, a waterproof surface can be easily constructed inside the inner panel 4b without requiring special skills.

Therefore, since the waterproof surface is not directly exposed to wind and rain, the waterproof material can be freely selected, construction is easy, and durability can be ensured. Post-construction inspections and repairs can also be easily carried out using internal scaffolding or floors inside the building.

In the above-mentioned embodiment, the guide rails 2 and 2' were fixed to the recesses on both sides of the base steel frame 10 to constitute the guide section 3.
As shown in the figure, the guide section 31 may be constructed by fixing a substantially T-shaped guide rail 2' to the outside of the base steel frame 1'. According to this, the pillars of the building can be used as the base steel frame and the work can be carried out. The procedure is further simplified.

Although the above-described embodiments are for the construction of a new building, the curtain wall installation method according to the present invention can of course also be used when adding various functional walls to the outer periphery of an existing building.

Regarding a single/multiple curtain wall, in this embodiment, the outer panel 4 is used as a double curtain wall 4.
a, an inner panel 4b and a connecting material 4C,
This outer panel 4a may incorporate various heat-related panels such as solar heat absorption panels, solar insulation panels, heat radiation panels, and panels that prevent or control heat transfer.
It incorporates radio wave absorbing panels and various lighting panels for advertising and expression media, or uses a combination of these to develop as a functional wall.
It is also possible to give the outer panel a large degree of freedom as a decorative material.

Furthermore, there is a hollow part in the connecting material 4C, and the air in the hollow part can be expected to have an insulating effect and a chimney effect.In addition, refrigerant, optical fibers, electric wires, etc. can be inserted into the hollow part as appropriate, and it can be used as a path for transmitting heat and other things. It can have various functions.

In addition, the inner panel 4b can be made of only a frame as a load transmitting material, and the weight can be reduced. In other words, the 1'Hl11 panel 4b is not limited by its name, as long as it has at least the function of a frame, and can also function as a heat insulating panel by using other highly heat insulating materials.

In this way, various functions can be differentiated by the double structure O as in the above embodiment, but if the outer panel 4a and the inner panel 4b themselves are made into a so-called multilayer structure, further functions can of course be added. The entire curtain wall may have a multilayer structure.

That is, the multiple curtain wall according to the present invention enables diversification of wall functions, and by combining these curtain walls, it is possible to easily create various composite walls. In addition, when used in combination with the curtain wall installation method mentioned above, it is effective not only for newly constructed buildings but also for adding new functions to existing buildings. Needless to say, there is no need for external scaffolding in this case, and the work can be done without having to remove the existing external scaffolding used for erecting pillars. Of course, this also applies to any of the curtain wall replacement work mentioned above.
