[0005]
[Means for Solving the Problems]
In the present invention for solving the problem, in the blindless structure of a screen in which a blind material is provided over substantially the entire length of a steel horizontal structural member, and an exterior material such as a panel or glass is disposed on the blind material, A hook-shaped upper holding portion extending over the entire length of the blind material is formed at least on the inner upper portion of the blind material, and the upper holding portion is engaged with an upper portion of a vertical flange portion of a horizontal structural member having a substantially T-shaped cross section. In addition, the inner lower part of the blank is attached to the lower part of the flange part (claim 1). According to this, the upper holding portion is engaged with the flange portion, and the blind material is integrated with the horizontal structure material while being hooked on the horizontal structure material, so that the assembly of the seamless material and the horizontal structure material is simplified. Therefore, it is easy to carry out the construction, and there is no need to transport with the blind material and the horizontal structural material assembled, and the heavy steel horizontal structural material and the transparent material can be transported separately.

[0006]
A hook-shaped lower holding member is screwed to a lower portion inside the blind material with a vertical screw, and the lower holding member is engaged with a lower portion of the flange portion (claim 2). By screwing the lower holding member with the vertical screw in this way, when pressure is applied to the screen, the screw bears shearing stress. It is possible to bear a larger force than when the effective screw portion bears pressure, and it is possible to reduce the number of screws when attaching the lower holding member when engaging the blind material and the horizontal structure material. This further facilitates mounting.
[0007]
The blank is provided with a drainage hole (claim 3). According to this, water that has entered the indoor side due to deterioration of the sealing material due to dew condensation or deterioration of weather resistance can be drained, and the operation is good.

Stand 2 is fixed to the frame.
[0009]
The blind 3 is made up of a blind material 13 and a horizontal structural member 14 as shown in FIG. The horizontal structural member 14 is made of, for example, a T-shaped steel material obtained by cutting a standard steel H-section steel in the width direction, and the horizontal structural member 14 extends in the horizontal direction on the indoor side (inside). Both ends of the horizontal portion 15 in the longitudinal direction are fixed to a bracket 16 fixed to an H-shaped steel 11 provided on a frame by screws 17 and welded via a reinforcing bar 18. The blind material 13 is a die material formed by extruding or drawing aluminum or an aluminum alloy, and has an upper outdoor vertical wall 20 erected above the outdoor end of the upper wall 19, and an indoor side at the indoor end. A vertical wall 21 is suspended from the indoor vertical wall 21, and a lower wall 22 is provided from the lower side of the upper wall 19 toward the outdoor direction from the lower side of the upper wall 19. A lower outdoor-side vertical wall 23 hangs down. From the indoor vertical wall 21, a dew condensation receiving wall 24 that extends upward toward the indoor side is extended, and a standing piece 25 is erected at the indoor side end of the dew condensation receiving wall 24, and the dew condensation receiving wall 24 is formed. A holding hanging piece 26 is provided to extend downward from an intermediate portion of the wall 24, and a hook-shaped upper holding portion 27 is formed on the seamless material 13. In addition, drainage holes 28 that open toward the lower wall 22 are provided on both sides in the longitudinal direction of the upper wall 19 of the blind material 13.
[0010]
Further, lid members 29 are attached to both ends in the longitudinal direction of the blank 13. As shown in FIG. 2, the lid member 29 has a water blocking portion 30 extending upward on the side of the condensation receiving wall 24, and is continuous with the water blocking portion 30 in the longitudinal direction of the seamless material 13. The bent seal material receiving portion 31 is formed. The lower end of the sealing material receiving portion 31 and the outdoor end of the condensation receiving wall 24 have a metal touch, and the metal touch portion (between the lower end of the sealing material receiving portion 31 and the outdoor end of the condensation receiving wall 24). ), A gap 32 is provided, and a blind space 33 surrounded by the upper outdoor side vertical wall 20, the upper side wall 19, and the indoor side vertical wall 21, the dew condensation receiving wall 24, the standing piece 25, and both ends. The lid member 29, the exterior material 4, and the sealing material 9 communicate with the dew condensation water receiving space 34.
[0011]
In the blind material 13, the upper holding portion 27 is engaged with the upper portion of the vertically extending flange portion 35 of the horizontal structural member 14, and the lower portion of the indoor-side vertical wall 21 is located at the lower portion of the flange portion 35. It is screwed with a screw 36 in the indoor / outdoor direction, and is integrated with the horizontal structural member 14 to form the blind 3. The number of the screws 36 is set so as to withstand the negative pressure acting on the screen 1 together with the holding hanging pieces 26. The blind 3 configured as described above is disposed between the cubicles 2, and the lower edge of the exterior material 4 between the upper outdoor-side vertical wall 20 and the indoor-side vertical wall 21 via the sealing material 9. The upper edge of the exterior member 4 is held between the lower outdoor-side vertical wall 23 and the flange portion 35 of the horizontal structural member 14 via the sealing member 9.

When the screen 1 is installed, the hook-shaped upper holding portion 27 is hooked on the flange portion 35, and the lower portion of the indoor-side vertical wall 21 and the flange portion 35 are screwed together with screws 36, so that the on-site assembly is easy. In addition, since the blind material 13 and the horizontal structural member 14 made of one member are assembled into the blind 3, the number of members is smaller than that of the conventional one, and the construction is simple. Since the assembly of the blind material 13 and the horizontal structure material 14 is simple, the blind material 13 and the horizontal structure material 14 can be transported separately when transported to the construction site. The weight of the blank 13 is reduced, and it is possible to prevent the blank 13 from being damaged by vibration or the like during transportation, thereby preventing the design of the screen 1 from deteriorating. Further, when dew condensation occurs, the dew drops accumulate in the dew condensation water receiving space 34, and the dew water is drained from the drain hole 28 through the gap 32 from the dew condensation water receiving space 34 through the blind space 33. Then, the water flows down the upper surface of the inclined lower side wall 22 and is drained to the outdoor side. Further, even when the sealing material 9 is damaged due to a decrease in weather resistance and rainwater enters the blind hole 3, the water is drained from the drainage hole 28. As described above, dew condensation and the like are drained to the outside of the room from the drainage hole 28, so that the rain is good.
[0013]
Next, another embodiment will be described with reference to FIGS. The same parts as those in the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted. At the lower side of the lower side wall 22 of the indoor-side vertical wall 21, a mounting piece 37 protruding in the outdoor direction is formed. A lower holding member 38 is integrally attached to a lower portion of the indoor vertical wall 21. The lower holding member 38 extends over substantially the entire length in the longitudinal direction of the blind material 13, has a lower upward hook shape, and is attached to the indoor vertical wall 21. The lower part of the flange portion 35 of the horizontal structural member 14 is engaged between the inner wall 39 and the indoor-side vertical wall 21. The lower holding member 38 is screwed by a plurality of screws 41 in a vertical direction to a mounting piece 37 of the indoor side vertical wall 21 with a screw stopper 40 formed at an upper end so as to protrude in the outdoor direction. The number of screws for stopping the lower holding member 38 is such that the lower holding member 38 can be prevented from dropping from the indoor-side vertical wall 21. When a negative pressure is applied to the screen 1, the screw 41 becomes Since it bears shear stress, it bears a larger force than the one that bears the negative pressure acting on the screen 1 with the effective screw portion as in the case of fixing the screw in the indoor and outdoor directions as in the first embodiment. Therefore, the number of screws 41 can be reduced, and the construction is further facilitated.
[0014]
【The invention's effect】
As described above, according to the present invention, the cross-sectional shape is substantially T-shaped, and the upper part of the hook-shaped part extending in the full length direction formed on the inner upper part of the seamless material is formed on the upper part of the flange part of the steel horizontal structural member. Since the holding portion is engaged and the lower portion of the blind material is attached to the lower portion of the flange portion, the assembly of the blind material and the horizontal structural member is simplified, and the construction can be easily performed. Therefore, the blind material and the horizontal structure material can be separately transported, and the heavy steel horizontal structure material can be prevented from being damaged by the weight of the horizontal structure material. Also, by screwing the hook-shaped lower holding member to the blind material with a vertical screw and screwing the lower holding member to the lower part of the flange, the screw can reduce the negative pressure acting on the screen by shear stress. Therefore, a large pressure can be borne, and the number of screws for stopping the lower holding member seamlessly can be reduced. In addition, since the drainage holes are provided in the seamless material, water such as dew condensation can be drained from the indoor side to the outdoor side, and the water treatment is good, which is preferable.
