[0001]
[Industrial application fields]
The present invention relates to a glass block panel used for the purpose of lighting, decoration, and the like, and an elastic waterproofing material used therefor.
[0002]
[Prior art]
Since a glass block for building is excellent in heat insulation and has translucency, it has been widely used as a material for a wall (panel) of a building.
[0003]
Hereinafter, the construction procedure of the glass block panel will be described with reference to FIG.
[0004]
First, a metal frame 11 made of a metal material such as stainless steel or aluminum is attached and fixed to the opening formed in the housing 10 of the building. A drain plate 12, anchor piece 13 and sliding members 14, 14 are attached in the groove on the inner peripheral surface of the lower side frame of the metal frame 11, and the inner peripheral surface of the side frame and the inner peripheral surface of the upper side frame (illustrated) The buffer material 15, the anchor piece 13, and the sliding materials 14 and 14 are attached in the groove portion of (omitted).
[0005]
Next, the glass blocks G, G... Are stacked in order from the bottom so as to secure the width of the sealing materials 16, 17 on the inner and outer surfaces of the metal frame 11 and to secure the joint width inside the metal frame 11. At this time, a mortar 20 is stacked on top, bottom, left and right joints while attaching ladder-like longitudinal strength bones 18 and lateral strength bones 19 formed by connecting two reinforcing bars between the glass blocks G at a predetermined interval. Laminate so that is fixed.
[0006]
Thereafter, in order to prevent rainwater from entering the interior or interior of the glass block panel, a waterproof layer 21 is formed on the joint between the glass blocks G, and a decorative joint layer 22 is formed thereon. In addition, the outdoor gap between the opening of the housing 10 and the outer periphery of the metal frame 11 is filled with a sealing material 24 such as polysulfide or silicone rubber via a backup material 23 to finish the surface. Furthermore, the sealing material 16 and 17 is filled into the indoor side and outdoor side clearances between the inner periphery of the metal frame 11 and the glass block G through the backup materials 25 and 26 to finish the surface. A plurality of drain holes 11 a are formed in the groove portion of the lower frame of the metal frame 11, and a drain hole 11 b is formed on the outdoor side of the lower frame of the metal frame 11. Even if it penetrates, it is made to drain from the drain hole 11b to the outside via the drain hole 11a.
[0007]
The sliding members 14 and 14 are members for cutting the metal frame 11 and the stacked mortar 20 and preventing them from contacting each other. When the metal frame 11 is deformed by an earthquake or the like, the sliding members 14 and 14 14 moves so that the force applied to the stacked mortar 20 can be weakened to prevent the glass block from cracking. Further, the backup materials 25 and 26 are members interposed between the sealing materials 16 and 17 and the stacked mortar 20, whereby the sealing materials 16 and 17 are attached to the glass block G only at two places on the side surfaces thereof. Since it adheres to the metal frame 11, the followability to deformation is improved, and even if the sealing materials 16 and 17 are deformed due to an earthquake or the like, the sealing performance is not easily impaired.
[0008]
[Problems to be solved by the invention]
Normally, rainwater does not enter the glass block panel or the room because it is blocked by the outdoor sealing material 16 and waterproof / makeup joints. However, the sealing material 16 may be deteriorated by long-term use. In addition, the waterproof layer 21 formed in the joint portion of the gap between the metal frame 11 and the glass block G has poor continuity with the metal frame 11, so that rainwater is generated particularly from the gap between the metal frame 11 and the glass block G. Easy to invade.
[0009]
Further, when the waterproof layer 21 is formed on the joint between the metal frame 11 and the glass block G, a waterproof material is often applied to the metal frame 11, and the waterproof material is applied to the metal frame 11, Even if the sealing material 16 is filled, it is difficult to fill it well, and there is a problem that the waterproof property is further lowered. In order to solve this problem, the waterproof material adhering to the metal frame 11 may be completely removed, but this operation is very complicated.
[0010]
As described above, rainwater easily enters from the gap between the metal frame 11 and the glass block G. However, the water that has penetrated into the metal frame 11 thus reaches the stacked mortar 20 through the backup material 25, and reaches the bottom frame of the metal frame 11. From the drain hole 11a formed in the groove portion, it flows into the inside. And the water collected in this lower side frame is discharged | emitted outside from the drain hole 11b formed in the outdoor side.
[0011]
However, this discharged water is mixed with the ash of the mortar 20 and when the amount increases, the lye is clogged in the drain hole 11b and closes the hole. The original function is not performed.
[0012]
As a measure to prevent clogging of the drain hole 11b due to this lye or the like, it is conceivable to enlarge the drain hole 11b. However, if the drain hole 11b is enlarged, dust, insects and the like enter from the outside, and these This is not preferable because it tends to block the drain hole 11b.
[0013]
The present invention has been made in view of the above circumstances, and its first object is to prevent rainwater from entering the metal frame even if the sealing material that seals the gap between the metal frame and the glass block deteriorates. It is providing the glass block panel which can be suppressed.
[0014]
In addition, the second object of the present invention is that even if the sealing material that seals the gap between the metal frame and the glass block deteriorates and rainwater enters the metal frame, water does not reach the stacked mortar and is discharged to the outside. Is to provide a glass block panel.
[0015]
[Means for Solving the Problems]
The glass block panel of the present invention is a glass composed of a metal frame fixed to an opening of a housing, and a plurality of architectural glass blocks laminated in a groove on the inner peripheral surface of the metal frame and integrated by stacking mortar. In the block panel, a sliding material is attached to both side surfaces of the groove portion of the metal frame so as to protrude upward from the groove portion.
[0016]
Moreover, the other aspect of this invention consists of the metal frame fixed to the opening part of a housing, and the several architectural glass block laminated | stacked in the groove part of the internal peripheral surface of a metal frame, and integrated by the stacking mortar. In the glass block panel, an elastic waterstop material having a sheet shape is fitted and fixed to the bottom surface and both side surfaces of the groove portion of the metal frame, and both end portions of the elastic waterproof material protrude upward from the groove portion. Features.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, since the slip material is attached to both side surfaces in the groove portion of the metal frame so as to protrude upward from the groove portion, the sealing material filled in the joint portion between the metal frame and the glass block is provided. Even if rainwater enters from the deterioration, the water is blocked by the protruding portion of the sliding material, so that the water can be prevented from entering the inside of the metal frame.
[0019]
Usually, the joint width between the metal frame and the glass block is about 15 mm. However, if the sliding length of the sliding member is 5 mm or more, there is an effect of suppressing water intrusion. The preferable length of the protruding length is 10 mm or more.
[0020]
The sliding material can cut the edge of the metal frame and the stacking mortar and prevent them from coming into contact with each other. When the metal frame is deformed due to heat, earthquake, etc., it absorbs the behavior applied to the stacking mortar by sliding. Any material that can prevent the glass block from cracking can be used. Moreover, since it is desirable that the sliding material has elasticity, weather resistance, and resilience, the material is preferably butyl rubber or vinyl chloride.
[0021]
In the present invention, the elastic waterstop material is fitted and fixed to the bottom surface and both side surfaces of the groove portion of the metal frame, and both end portions of the elastic waterstop material protrude upward from the groove portion of the metal frame. The sealing material filled in the joint between the glass block and the glass block deteriorates, and even if rainwater enters this part, the water is blocked by the both ends (protrusions) of the elastic water-stopping material. It is possible to suppress water from entering the inside.
[0022]
Also in the present invention, it is desirable to form a waterproof layer at the joint between the metal frame and the glass block, but when the waterproof material is applied to the surface of the stacked mortar, the waterproof material adheres to the metal frame. In order to prevent this, the waterproof material may be applied and formed in a state where the protruding portion of the elastic water-stopping material is temporarily bent to the metal frame side. By doing so, the upper surface of the metal frame is covered with both end portions (protrusions) of the elastic water-stopping material, so that the waterproof material can be prevented from adhering to the upper surface of the metal frame. .
[0023]
For example, even if rainwater enters from between the metal frame and the elastic waterproofing material, the water flows from the back surface side of the elastic waterproofing material to the drainage hole formed in the groove of the lower frame of the metal frame, and the lower side. It is discharged from a drain hole formed on the outside of the frame. Since this discharged water does not come into contact with the stacked mortar at all, it is not contaminated by mortar components such as lye, and it is possible to prevent clogging of the lye and the like with the drain hole.
[0024]
If the protruding length of the elastic water-stopping material is 5 mm or more, there is an effect of suppressing water intrusion, and preferably 10 mm or more.
[0025]
Further, when a water stopping ridge is formed along the longitudinal direction on the back surface side of the bottom portion of the elastic water stopping material, the water that has entered from between the elastic water stopping material and the metal frame is transferred to the back surface of the elastic water stopping material. Even if it flows into the side, it can be surely stopped by the water stopping ridge, and it is preferable because water can be prevented from flowing into the indoor side.
[0026]
Further, when the drainage concave portion is formed along the longitudinal direction on the back surface side of the bottom portion of the elastic water-stopping material, the water that has entered from between the elastic water-proof material and the metal frame is transferred to the back surface side of the elastic water-stopping material. Even if it flows into the water, it is preferable because water easily flows into the drain hole formed in the groove portion of the lower frame of the metal frame via the drainage recess.
[0027]
Any material can be used as the material for the elastic water-stopping material as long as it is flexible and has good adhesion to the metal frame, but elastic rubber such as EPDM and silicone is particularly suitable.
