Abstract

PURPOSE:To obtain excellent workability by forming a form which frames three sides and provides a press-in groove in its longitudinal direction and coating this frame material and glass with a fluid material and then pressing the glass into the press-in groove. CONSTITUTION:One side is preliminarily left over while the other three sides 1, 2 and 3 are connected to an L-shaped coupler 4, thereby forming a form. An engagement press-in groove is installed to the frame members 1, 2 and 3 at the degree of about 45. Liquefied silicone resin is applied to a part where the frame members and glass 6 are placed into direct contact with each other. The glass 6 is pressed into the press-in groove under the condition that the resin is still uncured. The other frame member 8 pressed in while it is being placed over the top of the glass 6. This construction makes it possible to prevent the silicon resin from flowing between the frame members and face bars and inhibit the generation of a clearance.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame structure for a face material in a curtain wall and the like, and a method for frame structure.

[0002]

2. Description of the Related Art Generally, in order to fix a face material, particularly glass, to a frame, it is attached through a so-called glazing channel.

On the other hand, in the specification and drawings of Japanese Utility Model Laid-Open No. 144988/1990, the outer appearance of the frame member and the face member are flush with each other to enhance the appearance and prevent the attachment of dust due to the step. Is disclosed. In addition, the present invention improves the glass retaining property by forming the inwardly inclined locking portion on the outer surface side, particularly in the cross section, and inserting the glass therein. In this case, the glass and the frame material are fixed with an adhesive, but under the comparison of the size with the cross-sectional wall thickness of the frame material, a general adhesive made of a silicone resin for filling with high viscosity is used. Considered a drug.

[0004]

However, when the glass is attached to the frame member through the glazing channel, the glazing channel may be curled or cut at the edge of the glass during the attachment. Further, since the glazing channel is usually made of rubber, it is inferior in durability and weather resistance, and the adhesion between the face material and the frame material is poor.

On the other hand, although the technique of the above publication has excellent appearance and has an effect of preventing dust from adhering due to steps,
From the description of the embodiment (including the drawings, particularly FIGS. 1 and 2), it is considered that the adhesive is filled after the glass is fitted, and even if the work is performed on-site, it can be produced in a factory. However, the workability is extremely poor. In particular, it is also a factor that deteriorates workability that the glass needs to be left stationary until the adhesive is cured.

[0006] Therefore, a main object of the present invention is to make a frame only by press-fitting the face material into the frame material, and thus to improve workability.

[0007]

A method of framing a face material according to the present invention, which has solved the above-mentioned problems, includes a temporary frame having one side left in advance and the other three sides framed and having a press-fitting groove along the longitudinal direction thereof. In a portion where the frame material and the face material are in direct contact, substantially the entire of at least one of the frame material and the face material is coated with a fluid material such as a liquid silicone resin, and this is in an uncured state,
The face material is press-fitted into the press-fitting groove of the frame material from the one side, and a frame material corresponding to the other one side is attached later.

The frame structure of the face material is a structure in which one side is left in advance and the other three sides are framed, and the face material is press-fitted into the press-fitting groove of the frame material having a press-fitting groove along the longitudinal direction, Further, at least one of the frame material and the face material in a portion in direct contact with the frame material is substantially entirely coated with a fluid material, and the corner portion of the face material is chamfered small. is there.

[0009]

In the present invention, as the face material, in addition to glass, a plate-like material having rigidity such as a metal panel, a stone material, and an artificial stone, or a composite plate in which a reinforcing plate-like body having a honeycomb structure is laminated on the back surface thereof Etc. can be used. However, since it is particularly effective in the case of glass, an example of glass as the face material will be mainly described.

According to the method of framing a face material of the present invention, liquid silicone is substantially all over at least one of the frame material and the glass in the press-fitting groove of the temporary frame in which one side is left in advance and the other three sides are framed. A fluid material such as a resin is applied, and in a uncured state, the face material is press-fitted into the press-fitting groove of the frame material from the one side, and a frame material corresponding to the other one side is attached later. Therefore, it is sufficient to leave the glass in a press-fitted state without positioning it in the press-fitting groove and wait for the silicone resin to cure.
No special jigs are required for positioning, and workability is excellent. Further, unlike the conventional example shown in the above publication, the gap is not filled with a silicone resin, but the silicone resin is applied to the contact surface of the frame material and / or the glass in advance, which is by press fitting. Therefore, with the press-fitting, the silicone resin does not flow between the frame material and the face material without causing any gap or void. Therefore, the sealing property is extremely excellent.

In addition, the coating thickness of the fluid material is very thin, and even if it deteriorates due to long-term use, the clearance with the frame material is practically negligible or very small, so that the fluid material does not exist in the press-fitting groove of the frame material. The glass does not rattle, and the glass retainability is extremely excellent. In addition, a low adhesive strength of the fluid material is sufficient, or the adhesive function itself becomes unnecessary. On the other hand, in the conventional publication description example, the silicone resin adhesive is filled, and the filling gap is enlarged,
When the silicone resin adhesive is deteriorated over time or deteriorated by vibration due to wind pressure, the amount of backlash becomes large, and in some cases, there is a risk of glass falling.

On the other hand, by chamfering a small corner portion of the glass in advance, there is no catching between the frame material and the press-fitting groove of the frame material at the time of press-fitting, and the press-fitting can be smoothly performed. There is no chipping.

From the viewpoint of the purpose, the fluid material referred to in the present invention is one that enhances the adhesion between the face material and the frame material, one that aims at the effect of the cushioning material, and one that secures the sealing property. There are things that expect adhesiveness, and you can select appropriate materials according to the purpose, but examples are modified silicone type, butyl rubber type, synthetic rubber type, urethane type, polysulfide type, acrylic type etc. Can be used. When a silicone resin is used, it is suitable for press fitting because it has excellent weather resistance as well as slipperiness. Moreover, since it has elasticity to some extent, it has the function of absorbing vibrations and protecting the glass.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 is an explanatory view showing a framework method of the present invention. Frame members 1, 2 having one side left in advance and the other three sides are formed.
3 is connected by, for example, L-shaped corner connecting members 4 and 4, and is framed to form a temporary frame. These frame materials 1, 2, 3
Has an engaging press-fitting groove 5 of 45 degrees, for example, as shown in FIG.

On the other hand, the liquid silicone resin 7 is applied to substantially the entire portion of at least one of the frame material and the glass at the portion where the frame material and the glass 6 are in direct contact with each other. Frame materials 2, 3 from the open side
The glass 6 is press-fitted into the press-fitting grooves 5 and 5 of the above, and finally also into the press-fitting groove 5 of the lower frame member 1. Then, the frame material 8 corresponding to the other side is attached. The upper frame member 8 is press-fitted while covering the upper portion of the glass 6 and is connected to the adjacent frame members 2 and 3 by using the corner connecting members 4 and 4 as described above.

The edges of the glass 7 in the embodiment are frame materials 1 to 1.
Since 3 and 8 have the press-fitting groove 5 of 45 degrees as shown in FIG. 4, they are also chamfered at an angle of 45 degrees as shown in FIG. In the case of having a press-fitting groove, glass 6A which is not chamfered can be used as shown in FIG.

When the silicone resin is applied to the glass 6 in advance, it can be applied by immersing the edge of the glass 6 in the silicone resin 7 stored in the bat 10 as shown in FIG. The other three sides can be similarly coated. This applied state is shown in FIG.

On the other hand, when the glass 6 is press-fitted, as shown in FIG.
As shown in FIG. 7 and FIG. 7, the corner portion of the glass 6 is chamfered in advance (the chamfered portion is indicated by reference numeral 6a) to prevent the frame material from being caught in the press-fitting groove 5 of the frame material. It is possible to smoothly press fit, and it is possible to prevent chipping of the corner portion of the glass 6. The chamfer may be arcuate instead of straight. This chamfer has the advantage that, when applying the silicone resin 7 and adopting the dipping method as shown in FIG. 8, it is possible to prevent the thickening of the silicone resin 7 at the corners where the surface tension becomes large when the glass 6 is pulled up. Also brings.

The coating thickness of the fluid material such as silicone resin is preferably 0.1 to 1.0 mm in dry thickness. 0.1 m
If it is less than m, the sealing properties will be poor, and if it exceeds 1.0 mm, it will cause sagging during press-fitting or the deterioration of the glass will cause it to rattle. This film thickness can be adjusted by the type of fluid material, its viscosity, liquid temperature, and the like.

The coating may be brush coating or the like. further,
It is also possible to apply the fluid material to the frame material side or both, instead of the glass 6 side. When the coating is completed and the framework is completed, it is possible to wait for curing by natural drying and also to accelerate heat curing. For example, when a silicone resin is used, hot air drying can be performed at 60 to 100 ° C. for 3 minutes to 120 minutes.

An example of the outer wall of a building framed according to the present invention will be described with reference to FIG. 9. Between the lip groove type vertical support frame 20 and the vertical support frame 21 in which the channel members are assembled in a staggered manner, respectively, the frame member 3, 2 is locked by the locking bracket 22, and the locking bracket 22 is fixed to the vertical support frame 2
The bolt 22 is fixed to 0 and 21. The space between the adjacent frame members 2 and 3 is sealed with a sealing material 24 and tight materials 25 and 25 are provided on the back.
The same applies to the opening wall surface.

FIG. 10 shows an example in which a honeycomb material 61 is reinforced on the back side of an aluminum alloy panel 60 as a face material, and the other mounting structure is basically the same as the example in FIG. However, in the example of FIG. 10, while the outer surface of the panel 60 and the outer surfaces of the frame members 2 and 3 are flush with each other,
In the example of FIG. 9, the glass 6 is in a protruding relationship.

In order to prevent the frame members 2 and 3 from exhibiting a metallic luster, a surface material (not shown) such as rubber or plastic that does not show luster can be attached to the stepped portion.

[0024]

As described above, according to the present invention, it is possible to form a frame only by press-fitting the face material into the frame material, and thus the workability is excellent.
