Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aluminum sash such as a window sash and a curtain wall.

[0002]

2. Description of the Related Art Conventionally, an aluminum sash has been set back from the outer wall surface from the viewpoint of preventing water leakage, but in recent years, the glass surface becomes the same surface as the outer wall surface as the performance of the aluminum sash has improved. The design sash, which is expected to have a synergistic effect of reducing the degree of dirt on the glass surface, because the entire outer wall has a smooth design with no unevenness and the rainwater will wash off the dirt on the glass surface naturally when it rains. Furthermore, a design sash has been proposed which uses heat ray reflective glass to project an external shadow by making the entire wall surface a large mirror wall. However, attempts have been made to reduce the number of aluminum fixing the glass and the width of sight, and to reduce the step difference of the frame on the glass as much as possible. Therefore, in the case of an example of a horizontally long continuous window as shown in FIG. 1 and a glass curtain wall in FIG. 2, the vertical aluminum member exposed to the outside of the glass surface is removed so that it is located only inside the glass surface. Back mullion, STRUCUAL GLAZ, which secures the glass to the back mullion with a structural adhesive on the glass vertical edge
A technique called ING SYSTEM has also been proposed.

[0003]

As for the horizontal aluminum frames 3 and 4 for fixing the glass in FIG. 1, it is practically impossible to use a long material having a frontage of a building, and it is an expansion that secures joints. Must be a joint. That is, aluminum metal has a much larger coefficient of thermal expansion than concrete and expands when heated in the summer to extend in the longitudinal direction of the material. Occurs, and the larger the span, the greater the amount of elongation and the greater the degree of bending.

However, the aluminum material must have an appropriate span according to the size of the cross section, and the joint portion must be an expansion joint that secures joints in consideration of the expansion margin of the aluminum material. However, the work efficiency in the factory is poor, and it will be difficult to bring it into the construction site. From the above point of view, it is general that the window frame is manufactured with an appropriate size to form an expansion joint that is connected while maintaining joints at predetermined intervals, and the joints are sealed with a sealant. However, in terms of appearance, a lateral flow streamline design is inconveniently divided at the joints, and the glass groove 10 of the frame as shown in FIG. 5 is formed by U-shaped thin teeth. Since the contact area of the sealant is small, a method of bridging the backing material to the joint, fitting the glass, and filling the gap with the sealant while kneading and finishing is adopted. In addition to repeated expansion and contraction of aluminum materials over a long period of time, the adhesion durability of the seal materials deteriorates due to earthquake lateral shaking, etc., and the adhesion between aluminum materials and glass breaks, creating gaps. It was the cause of water leakage. Although the performance of aluminum sashes has been improved in recent years and water leakage accidents have been mitigated, the fact is that most of the water leakage is caused by the seal breakage at the joints.

On the other hand, when fixing glass in glass construction,
Wet glass construction, such as sticking with a curing tape and kneading the sealant with a spatula so that the glass sealant does not stick out to a predetermined portion, requires skill and has a drawback that the working process is long. On the other hand, the wet glass construction method,
If the glass surface or aluminum surface is wet, the glass sealant will not be able to adhere to it, so it cannot be applied even in the rain, and there is the drawback of being affected by the weather. The above glazing method is
In addition to requiring skill, the construction period is long depending on the weather, which is a big problem in view of the actual situation of the construction industry, which is a chronic shortage of workers. Furthermore, the sash whose aluminum member is exposed to the outside of the glass surface radiates heat from the aluminum part that comes into contact with the outside air, resulting in poor heat insulation.In winter, the indoor side aluminum material cools, causing dew condensation on the surface. However, there is a drawback that dew condensation tends to occur. To summarize the above problems,
It is as follows. That is, a) the appearance of the horizontal frame joint is reduced, b) water leakage due to the seal rupture of the horizontal frame joint, c) the wet glazing method requires skill, and the construction period is long and it depends on the weather. d) A large amount of heat is radiated from the aluminum member exposed to the outside air, and the heat insulating property is inferior.

Therefore, the present invention solves the drawbacks of the above conventional ones.

[0007]

For that purpose, an organic flexible gasket made of inorganic silicon rubber or chloroprene rubber is continuously covered like an outer skin on the upper frame and the lower frame of the horizontal windows. Connected to an endless frame material, the upper and lower aluminum frames are not exposed to the outside air, and the lower frame or inner crosspiece is covered with a skin-like gasket.The above gasket is a gasket with a U-shaped cross section gutter. The rainwater that invades into the gasket gutter is guided to the gasket gutter, and the water level of the gutter is not raised through a drainage pipe arranged at the bottom of the gutter to prevent water leakage.

[0008]

With the above configuration, a) an upper frame which is expansion jointed in a straight line,
Both ends of the lower frame are free from being constrained. Freely thermal expansion and contraction of the inside of the skin-like gasket to be covered (joint waterproof seal does not break, hiding effect that joints are not visible) b) The expansion joint is continuously covered with endless skin-like gasket without waterproofing. Upper frame side → Draining action Lower frame side → Horizontal gutter action c) The aluminum material facing the outside is covered with a skin-like gasket so that it does not come into direct contact with the outside air and prevents radiation. Prevents dew condensation by preventing temperature drop on the indoor aluminum surface in winter. d) A silicone rubber skin-like gasket having a colorful design effect a to d.

[0020]

Since the gasket is made of a flexible material such as synthetic rubber made of silicone rubber or chloroprene rubber, it can be rolled up or folded and is easy to carry, and can be easily connected to the expansion joints in the window frame group. The continuous coating gives the appearance of a long piece of material, eliminating the work of filling and kneading the expansion joint joints with the waterproof seal, and the aluminum frame can be freely expanded and contracted within the gasket. In addition to eliminating the water leakage due to breakage of the waterproof seal adhesion, it enables glass construction without being affected by the weather and requires less skill than the wet construction method in which a waterproof sealant is installed in the glass groove gap. It has the effect of significantly shortening the construction period.
In addition, the conventional method sash, in which the aluminum material is exposed directly to the outside air, has the drawback that the heat radiation from the aluminum part exposed to the outside air is large and the heat insulation is poor, and dew condensation occurs on the indoor side aluminum surface. Since the structure is such that it is wrapped in the gasket and does not come into contact with the outside air, the amount of heat radiated to the outside air is reduced and the heat insulating effect is improved, so that there is an effect of reducing dew condensation on the indoor aluminum surface.

Further, by making the color gasket containing the coloring pigment in the silicone rubber the same color as the glass, the frame material is made less conspicuous and a more flat glass wall appearance can be obtained. In addition, the colorful gasket is made of aluminum. It can provide a unique appearance that cannot be expressed with metal. Furthermore, the integral aluminum mold material had to be finished in the same color on the indoor side and the outdoor side, but it has the effect of finishing the desired colors on the outdoor side and the indoor side, respectively.
