Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a waterproof louver (louver, louvre) connection structure, and more specifically, a vertical waterproof louver connection structure or joint that can be appropriately installed in buildings, factories, power plants, gymnasiums, warehouses, houses, etc. Regarding the structure.

[0002]

[Prior art]

 Conventionally, as a waterproof louver installed in buildings, various factories, power plants, gymnasiums, warehouses, houses, and other places, for example, wood, synthetic resin, or metal blades are used, and these are used in the specified frame. It is composed by assembling into. In this case, the blade plate member is usually attached in a horizontal type in which the installation direction is arranged in the horizontal direction, that is, a so-called hundred-leaf box type.

[0003] The vane plate material is installed in such a lateral direction to prevent wind and rain from above or obliquely above, and to prevent invasion of wind (rain) from the lateral direction during strong wind and rain. Furthermore, it is intended to perform various functions and functions such as waterproofing, daylighting, ventilation, smoke emission, etc. while effectively preventing the direct entry of sunlight (solar radiation). Or it has been adopted regardless of the Japanese style.

However, when observing in detail the louvers of the type in which the vane plate material is installed in the horizontal direction, which has been traditionally taken in such a way, the rainwater collected by each vane plate is gradually removed. It has a weak point that it easily hangs down on the side blades and scatters, and easily enters the louver, and the effect of shielding wind and rain from the left and right lateral directions is not always sufficient. It was found that the problem of shielding becomes remarkable when the louver becomes particularly large.

The inventors of the present invention have installed the respective vanes in the vertical direction instead of in the horizontal direction, and by adding various creative ideas to the conventional horizontal louver. We have developed and applied for a series of vertical waterproof louvers that can efficiently prevent the entry of rainwater and wind, and have excellent waterproofness, sound insulation, breathability, and daylighting, which have solved all of the above drawbacks. However, these are actually put into practical use (Japanese Patent Application No. 59-120688, Japanese Patent Application No. 5-73984, Japanese Patent Application No. 6-326, etc.).

FIGS. 1 (a) to 1 (c) show specific structural aspects of constituent members obtained by improving and improving the waterproof louver of Japanese Patent Application No. 59-120688. 1 (a) is a cross sectional view thereof, FIG. 1 (b) is a side view, FIG. 1 (c) is a front view, and FIGS. 1 (b) and 1 (c) are FIG. 1 (a). It is shown in a reduced size compared to. 1 (a) to 1 (c), reference numerals 1 and 2 _denote frame bodies provided at both left and right ends, respectively, and a plurality of blade plates A _{1 to} A _n are arranged at equal intervals therebetween, and adjacent blades are provided. Spaces S _{1 to} S _n are formed between the plates. Further, reference numerals 3 and 4 _denote frame bodies provided on the upper and lower edges of the blade plates A _{1 to} A _n , respectively. The blade plate A is integrally assembled by these and the frame bodies 1 and 2 on both left and right sides. A louver unit consisting of _{1 to} A _n is configured.

Further, each of the vane plates A _{1 to} A _n constituting the louver unit is made of a strip-shaped plate made of a metal such as aluminum or another material, and has a width as shown in FIG. The cross-section is approximately right angled (about 90 °) at the center of the direction, and the bent part 5, the protruding part 6 and the folded part 7 described below are overlapped with each other. It is located in These can bend the path of wind and rain from the outside, and prevent wind and rain from entering the indoors.

The blades A _{1 to} A _n are provided with a projecting piece 6 on the back side of the bent portion 5, and the direction thereof is parallel or substantially parallel to the surface of the louver as shown in FIG. 1 (a). Is provided. Although the blades A _{1 to} A _n are configured and arranged so that the bent portion 5, the protruding piece portion 6 and the like are on the left side in FIG. 1A, they are arranged in the opposite left-right direction [that is, FIG. 1A]. It is also possible to construct and arrange so that the bent portion 5, the folded portion 7 and the like are on the right side.

In addition, air is allowed to flow between the indoors and outdoors through the spaces S _{1 to} S _n formed between the adjacent vanes, and [when installed, as shown in FIG. as described, the upper outdoor side, the lower is the indoor side], the ventilation through the space S ₁ to S _n, performs smoke, etc., also in which to perform lighting and the like. In this case, by using a material having a high light reflectance, such as aluminum (including aluminum alloy), as the material for the pedestal plate, the daylighting effect can be further enhanced.

The upper and lower edges of the blades A _{1 to} A _n are brought into contact with the frame bodies 3 and 4, and they are fixed at appropriate places by, for example, screws, bolts / nuts, rivets or other appropriate fixing and fixing means. (Although not shown in the figure, the fixing can be performed by an appropriate means adopted as this type of fixing method). Further, the number n of the vanes A _{1 to} A _n is appropriately set depending on the installation location of the louver, the dimensions of the vane itself, the overall dimensions of the louver, and other conditions such as design.

Further, the tip end of the projecting piece 6 is provided with a folded-back portion 7 provided to the outside, that is, toward the outdoor side, and the folded-back portion 7 is folded as shown in the figure. It is needless to say that not only the case of the embodiment but also the structure can be folded back into an arc shape, a curved shape, or the like. By these, it is possible to prevent the intrusion of wind and rain from the outdoors to the inside, to catch raindrops here, and to collect and drop them. In this case, a groove is formed in the vertical direction by the back surface of the bent portion 5, the abdominal portion of the protruding piece portion 6 and the folded portion 7, so that the water collected here can flow down. In addition, a bent portion 8 directed inward is provided at the outer edge of the strip-shaped strip, that is, the edge on the outdoor side, to reduce the pressure of wind and rain from the outdoors to the interior. There is.

Further, a vane plate extension portion 9 is provided at an inner edge portion having a V-shaped cross section, that is, an edge portion on the indoor side. As shown in FIG. 1 (a), the extension portion 9 extends a predetermined width in parallel with the projecting piece portion 6, and the end portion of the extension portion 9 is provided with a bent portion 10 that is bent inward in a lateral cross section. By this, it is possible to prevent the remaining raindrops from entering the indoor space, and also to receive the raindrops here and collect them to let them flow down. Further, the entry (invasion) of raindrops from the outside to the inside can be prevented by the back surface of the bent portion 8, the abdomen of the protruding piece portion 6 and the folded portion 7 if it is a normal wind and rain. By providing the bent portion 10, the entry of raindrops can be almost completely prevented even in the case of strong wind and rain such as a typhoon, and the wind direction toward the inside can be finally changed to reduce the wind pressure.

The waterproof louver shown in FIG. 2 was proposed in the above-mentioned Japanese Patent Application No. 5-73984 and Japanese Patent Application No. 6-326, and further improved and improved on the above-mentioned louver. It Without changing the basic structure of installing the blade plate in the vertical direction, the folding part 8 of the outdoor side edge and the folding part 10 of the indoor side edge of the vane plates A _{1 to} A _n are circular. It is configured in an arc shape, and in addition, the bending angle of the V-shaped cross section of the vane plate is greatly expanded to an obtuse angle, which is approximately 110 ° to 130 ° (the lower limit is effectively up to about 105 °). ), The centrifugal force is used more effectively so that not only rainwater can be prevented from entering, but also the functions such as ventilation, smoke emission, and daylighting can be sufficiently maintained, and the aperture ratio can be 50%. It is something that can be made big before and after.

In the case of the waterproof louver shown in FIG. 2, each vane plate A _{1 to} A _n has a substantially obtuse angle (in FIG. 2, an obtuse angle of about 107 ° is drawn) at a substantially central portion thereof. It is formed in a V shape, which is a characteristic part of the bent portion 8 which has an arc-shaped cross section and the bent portion 10 which has an arc-shaped cross section. It is to be noted that each reference numeral in FIG. 2 is shown by the same reference numeral in correspondence with the reference numeral given in FIGS. ) Is the same. Further, the cross-sectional shape formed by the protruding piece portion 6 and the folded-back portion 7 is, for example, the bent portion 8 within a range in which the above-mentioned members can achieve their functions including imparting centrifugal force to the circulating air. A suitable shape such as an arc shape similar to the bent portion 10 or a curved shape can be used.

In this louver, in addition to the above-mentioned characteristic portions, by including the above-mentioned characteristic portions and, it is possible to impart a centrifugal force to the air flowing between the vane plates, and to significantly reduce the resistance of the circulating air. In this regard, as shown in FIG. 1, when the angle is set to a substantially right angle, the porosity is limited to 40% at the maximum, whereas the louver shown in FIG. As a result, even if the characteristic portion, that is, the angle of the V-shaped cross-section is widened significantly, the porosity can be greatly improved while maintaining the function and action as a waterproof louver. .

The above are only a few examples of various vertical louvers that have been studied and developed so far. These waterproof louvers are, for example, as shown in FIGS. 1 (a) to 1 (c) and FIG. A plurality of blades are arranged at fixed intervals between the left and right frame bodies, and are manufactured in fixed units, and installed in the required places. When installing this louver in a wide and wide installation location in the lateral direction, it is necessary to install multiple louver units side by side so that each louver unit has a predetermined width. In this case, adjacent louver units need to be connected to each other via a seal member or the like.

In the present specification, a unit in which a plurality of vanes are arranged and fixed between the left and right frame bodies as described above is referred to as a “louver unit” or “louver unit body” as appropriate. . In addition, these "louver units" and "louver unit bodies" mean that a plurality of blades are arranged at equal intervals without using a frame body on both the left and right sides or the left and right sides. It is meant to include those fixed by an appropriate means such as the body.

FIGS. 3A and 3B show various vertical louver units connected to each other at the installation site, for example, a plurality of louver units as shown in FIGS. 1A to 1C and FIG. It is a figure which shows one aspect at the time of installing together. Of these, FIG. 3 (a) shows an example in which adjacent louver units are connected to each other, and FIG. 3 (b) shows three louver units connected to each other (reference numeral W _{1 in the} drawing). , W ₂ and W ₃ ) are viewed from the outside (front view). In FIGS. 3 (a) and 3 (b), the same reference numerals are used for the same or similar members as those shown in FIGS. 1 (a) to 1 (c) and FIG.

In FIG. 3A, 11 is a sealing material, 12 is a rigid fixing member for holding the sealing material 11 with a predetermined space between the frame bodies 1 and 2, and 13, 13 ′ and 14 are fixed. It is a rigid member for fixing the member 12. The left and right louver units are connected by these respective members. First, the rigid members are respectively attached to the frame 2 of the louver unit and the frame 1 of the right louver unit shown on the left side of the drawing. 13 and 13 'are fixed by a fixing means such as a rivet 15. Then, the rigid fixing member 12 is fitted and inserted between them, and the rigid fixing member 12 is fixed from behind by the rigid fixing member 12.

At this time, the rigid member 14 is brought into contact with one or both of the rigid members 13 and 13 ', and is fixed by an appropriate fixing means such as an adhesive. Next, a sealing material 11 is applied to the recess formed by the frame 2 of the left unit body, the frame 1 of the right unit body, and the fixing member 12, and the exterior members 16 and 17 are attached to the upper and lower ends thereof, respectively. Completed the joint installation of both louver units. FIG. 3 (b) shows a state in which the three louver units are connected, and the portions indicated by L in FIG. 3 (b) are the respective connecting portions.

However, in the conventional connection method as described above, due to the presence of the connection portion L, the effect of preventing rainwater intrusion is reduced by that amount, and the functions and actions such as ventilation, smoke emission, and daylighting are also reduced by that amount. I will let you. In addition, there is a problem with the appearance after finishing the connection installation, which not only spoils the landscape but also increases the cost due to the need for several types of members as described above. It had a drawback that it was time-consuming. 4 (a) and 4 (b) show a mode in which the louver units are connected in a "cubic" form. In this mode, a large number of louver units are arranged at intervals, and the openings between adjacent frame bodies are as indicated by reference numeral H in FIGS. 4 (a) and 4 (b). The so-called "stand-up" is used for connection, and even in this case, there are still the drawbacks described above.

[0022]

[Problems to be solved by the device]

 The present invention was made to solve such problems in the conventional vertical waterproof louver connection structure, and in a vertical waterproof louver in which a plurality of blades are installed vertically, The purpose of the invention is to provide a joint structure or a joint member for joining and connecting the louver units, so that the vertical water-proof louver can only sufficiently prevent its entry, that is, rainwater and wind. Rather, it maintains various functions and functions such as ventilation, smoke emission, and daylighting, does not impair the performance as a waterproof louver, and also eliminates the external appearance inconsistency as in the past. (Landscape property and design property) are added so that they can be retained.

Hereinafter, the joint structure of the present invention will be described in more detail with respect to its form, mode, action and effect, etc., but it goes without saying that the present invention is not limited to these modes. 5 to 9 are views showing several examples of the configuration mode and the like of the present invention, and FIGS. 5A to 5C show an example of the configuration mode and assembly sequence of members necessary for the configuration. . Z also is a view 6 (a) ~ (c) are pieces Za and pieces Zb for explaining how that make up the assembly of Z ₁ from diagram (sectional view), FIG. 7 to FIG. 8 in the present invention _In the configuration and assembly of ₁ , various other aspects of the contact fitting portion of the piece Zb to the piece Za are shown.

FIG. 9 shows a strip-shaped plate body having a braces “[” shape in its cross section in the member Za of (A) described above so as to be provided with extension portions in the back direction from both sides of the braces “[” shapes. It is a figure which shows the aspect made. Further, FIG. 10 is a view showing a state after completion of the assembling thereof [corresponding to the aspect shown in FIGS. 5 (a) to 5 (c)]. 5 to 9, the same members and portions as those shown in FIGS. 1 to 4 are denoted by the same reference numerals, and the blades are denoted by A in FIGS. _{1 to} A _n, and in FIGS. 5 to 6, different symbols are attached as Xn _-1 , Xn, Y ₁ , Y _2, ..., Z ₁ , Z ₂ . The materials are the same, including the points having the spaces S _{1 to} S _n between the blades.

In FIGS. 5A to 5C, X and Y are louver units, and these louver units X and Y are basically the same as the louver unit bodies W _{1 to} W ₃ described above. . Z is a joint member that is arranged and fixed between the X and Y and connects the two. As shown in the drawing, the right end of the louver unit X is not provided with a frame body as indicated by reference numeral 2 in FIGS. 1 (a) and 2 and the blade plates ... Fixing and holding X _n-1 , X _n Is performed with upper and lower frames and the like as shown by reference numerals 3 and 4 in FIGS. 1 (b) to 1 (c). In addition, the left end portion of Y is not provided with a frame body indicated by reference numeral 1 in FIG. 1A and FIG. 2, and the blade plates Y ₁ , Y ₂ ... Y _n-1 , Y _n are fixed and held. Is performed with upper and lower frames and the like as shown by reference numerals 3 and 4 in FIGS. 1 (b) to 1 (c). The joint member Z is fitted between the both ends, and thereby the louver units X and Y are connected.

In FIG. 5A, as a unit body of the joint member, three blade plates (Z out of Z ₁ composed of Za and Z b, Z ₂ and Z ₃₎ are used. The blades Z ₂ and Z ₃ are the same as the blades X and Y), and are fixed at equal intervals. The number of blades is not limited to three, and may be two or four or more, and the joint member may be composed of only one Z ₁ . In any of these cases, a vane plate Z ₁ composed of a member Za and a member Zb is used as the vane plate for the end portion as shown in FIG. When forming with only one of Z ₁ as a joint member is composed of only slats Z ₁ is composed of a member Za and member Zb.

When Z ₁ alone is used as a joint member unit, it is independent, but when Z ₁ is included in two or more sheets, as described above, Za (Z a and Z b that constitute Z ₁₎ Za), Z ₂ , Z ₃ ... Zn are integrally connected and fixed in advance at equal intervals. There are no particular restrictions on the method of connecting and fixing them, but for example, the upper and lower ends of the blade plate [Za, Z ₂ and Z _{3 in} FIG. Use to fix. In this case, particularly in the case of a long louver in the vertical direction, it may be connected and fixed using a thick plate or the like at appropriate positions such as the upper and lower end portions as well as the long central portion.

FIGS. 6A to 6C are views (cross-sectional views) showing the assembly method for constructing Z ₁ from the member Za and the member Zb. As shown in FIG. 6B, the member Za is formed by cutting a part of the V-shaped section of the blade Z ₂ (= Z ₃ ...). As shown in FIG. 6A, a member Z b corresponding to the cut portion is brought into contact with and fixed to the piece Za. The member Za is similar to the case of Z ₂ (= Z ₃ ...) In that the bent portion 8, the extension portion 9 and the arc-shaped bent portion 10 are provided. , The reference numeral 18 is also used to indicate the back of the member Za), and its cross section is formed into "braces"["" and [where "braces"["" Means that the engaging portions 19 and 20 on both sides of the bracket are included], and the engaging portions 19 and 20 for abuttingly engaging the member Zb are provided.

In the present specification, portions corresponding to the locking portions 19 and 20 are also referred to as both side portions. Further, the size, the degree of bending, etc. of the bent portion 8 are appropriately set, but instead of being bent, the edge of the bent portion 8 may be simply rounded. Also regarding the extended portion 9 and the arc-shaped bent portion 10, the size thereof, the extension length of the extension portion 9, the degree of the arc of the arc-shaped bent portion 10, and the like can be appropriately set. Depending on the size of the bend 10, the extension 9 can be substantially zero, or instead of being bent, its edge can be simply rounded. In the present specification, the “bent portion” or “arc-shaped bent portion” has a meaning including these aspects. And these points are the same for the parts corresponding to these in the louver unit.

On the other hand, the member Zb is similar to the case of Z ₂ (= Z ₃ ... Zn) in that the member 5 has a bent portion 5, a protruding piece portion 6 and a folded portion 7, but a cross section including the bent portion 5 Both ends 21 and 22 of the strip-shaped portion formed in a V shape are configured to abut and engage with the engaging portions 19 and 20 of Za, respectively. As a result, the member Zb is brought into contact with and locked to the member Za so as to be fixed. The contact and locking of the member Zb with respect to the member Za performed at the installation site of the louver is performed from the lateral direction with respect to the member Za [from the bottom side to the upper side with respect to Za in the case of FIG. 6 (b)]. Or, from the upper direction to the lower direction], insert and abut and fix as shown in FIG. 6 (c).

In FIG. 6C, reference numerals 23 and 24 indicate contact and locking portions of the two, and FIG. 7A shows a portion corresponding to the portion indicated by reference numeral 23 in FIG. 6C. Is an enlarged view of. The shape and structure of the abutting and locking portions in the present invention are not particularly limited, and any suitable shape and structure can be adopted, but FIGS. 7 (b) to 7 (d) show a few of them. There is. In this case, the shape and structure of the side portion of the member Za, that is, the portion indicated by reference numeral 19 in FIG. 6B and the portion corresponding to the side portion of the member Zb are configured in accordance with each of these aspects. . That is, these are the portions denoted by reference numerals 19, 20, 21, and 22 in FIGS. 6A to 6C.

Next, after abutting both of them, the member Zb is fixed to the member Za. Although FIG. 6 (c) shows the case of fixing with screws (see reference numeral 24 in FIG. 6 (c)), the fixing is suitable for screws, bolts / nuts, rivets, etc., as well as the contact surface. It is carried out by an appropriate means such as interposing an adhesive. Further, in FIG. 6 (c), the portion corresponding to the reference numeral 23 may be fixed by these means in addition to the above locking or instead of such locking.

As another mode of the member Za in the present invention, both sides thereof are made relatively long as shown in, for example, FIG. 8B, and recesses are provided in the middle of each side as shown. Further, it is also possible to abut and lock a member Zb having a corresponding convex portion as shown in FIG. 8 (a).

Further, as another aspect of the member Za and Zb corresponding thereto in the present invention, as shown in FIG. 9B, for example, as shown in FIG. The strip-shaped plate may be configured so as to have strip-shaped extensions extending in the back direction from both sides of the curly bracket "[", and both ends of the member Zb may be abutted and locked thereto. . In this case, the both side portions are short or slight as shown by reference numerals 25 and 26 in FIG. 9 (b), and strip-shaped extensions are provided from both sides in the back direction as shown by reference numerals 27 and 28. Both end portions 29 and 30 of the member Zb as shown in (a) are brought into contact with each other and fixed by screws or other appropriate means. FIG. 9 (c) shows the contacting and fixing state of both.

By the way, FIG. 5A shows a joint member in which three blade plates (Za, Z ₂ and Z ₃ ) containing Za are integrally connected and fixed, but not Z ₁ alone as the joint member, When two or more (Za and Z ₂ ) or three (Za and Z ₂ and Z ₃ ) or more are connected and fixed to form a joint member, a louver unit (referred to as Y in FIG. 5B). Unit], the blade plate on the side adjacent to Z ₂ (in the case of 2 sheets) and Z ₃ (in the case of 3 sheets) [indicated by reference numeral Y _{1 in} FIG. 10 corresponding to FIGS. The vane plate] preferably has the same structure as Z ₁ . In this case, this Y ₁ is composed of Ya and Yb (see FIGS. 5B to 5C).

The leftmost blade plate Y ₁ in the louver unit Y in FIG. 5B shows a mode of the blade plate on the side opposite to the blade plate Z ₃ . 5 (b) to 5 (c), Ya and Yb are members corresponding to Za and Zb in Z ₁ and have the same shape and structure as those (the final shape of Y ₁ is Z _1). And Ya and Yb may be different from Za and Zb). In this way, the leftmost blade plate Y ₁ of the louver unit Y is composed of Ya and Yb, so that when the joint member composed of a plurality of blade plates is installed at the installation site, it is In FIG. 5B, between the louver unit X and the louver unit Y], the joint member can be fitted and inserted more smoothly.

Next, a process of joining the louver units X and Y by this joint member will be described. First, the louver units X and Y are arranged and fixed at a required installation place. At this time, the width occupied by the joint member Z is set with a space between both X and Y [in FIG. 5 (b), at this point, the joint member Z is not present]. After that, the joint member Z is laterally fitted and interposed between them, and is arranged and fixed as shown in FIG. 5B. The arrow (↓) between FIG. 5 (a) and FIG. 5 (b) indicates the fitting direction of the joint member Z, but this fitting direction is from the indoor side [from the bottom in FIG. 5 (b). [Upward]] may be performed.

Next, after the member Zb is fitted in the member Za from the lateral direction, both the members Za and Zb are fixed by abutting and locking them so that the state of FIG. 6C is obtained. The arrow (↑) between FIG. 5 (b) and FIG. 5 (c) indicates the fitting direction of the member Zb. This fitting direction is from the outdoor side [from the top in FIG. 5 (b)]. Downward] can be done. Further, as for the method of locking and fixing the member Zb with respect to the member Za, as shown in FIG. 6, after fixing both ends 21 and 22 of the member Zb to the locking portions 19 and 20 of Za, respectively, they are fixed. .

The fixing may be performed with screws, bolts / nuts, rivets, or the like, or may be performed by interposing a suitable adhesive on the contact surface. As an aspect thereof, a portion 23 in FIG. 6 (c) is bonded with an adhesive, and a portion 24 in the figure is fixed with a screw, and the portion 23 is only locked [FIG. 7 (a)- (D)], it is needless to say that an appropriate combination such as fixing the 24 part with rivets or screws, fixing both the 23 part and the 24 part with screws, rivets, or the like can be performed.

The above is for Z ₁ in the joint member Z, but the same is true for the leftmost blade plate Y _{1 in} the louver unit Y, and in FIG. 5B to FIG. 5C, Ya is Za And Yb corresponds to Zb. The fitting and assembling of the member Yb with respect to the member Ya can be performed in the same manner as in the case of Z ₁ . When three or more louver units are connected and installed, at least one of the left and right ends of the louver unit has a blade plate corresponding to Y ₁ (Z ₁ ) at one of its left and right ends. In addition, the other outermost end is not provided with a frame (that is, in FIG. 5A, it is a blade plate corresponding to Xn, and the frame is not provided on the right side).

The present invention is not limited to the examples illustrated above, and is applied as a joint member of various vertical waterproof louvers. In this case, the shape of the member Z ₁ having (A) to (B) and one or more blades Z ₂ , Z ₃ ... Connected to the member Z ₁ is adopted by various vertical waterproof louvers. It has a structure that corresponds to the shape and structure of the blades (including various shapes and structures of the bent and folded parts on the outdoor side and indoor side). FIG. 10 shows an example of the state after the assembly is completed as shown in FIGS. 5A to 5C, and FIG. 11 shows the joint member according to the present invention. It shows a state in which dozens of louver units are connected and installed. Note that reference numerals 31 and 32 in FIG. 11 denote strip-shaped exterior members.

[0044]

[Effect of device]

 According to the present invention, the louver unit does not need the frame bodies 1 and 2 at each end of the adjacent louver unit bodies as in the above-described conventional case, and does not require a sealing material or a stand between them. Can be connected. Therefore, in the present invention, the conventional method does not reduce the functions and effects of ventilation, smoke emission, daylighting, and other louvers that are reduced by the frame bodies 1 and 2, the sealing material and the erection. .

Further, in the present invention, since the joint member is made of the same member as the louver unit constituent member also in the joint structure portion, rainwater intrusion (infiltration) is sufficiently prevented even in the joint member portion, and ventilation, Sufficient smoke emission, daylighting and other functions and functions are maintained, and the performance as a louver is not impaired. Further, since it is not necessary to use a frame body, a seal member, or a stand between the louver units, for example, as shown in FIG. 11, there is no appearance mismatch, and excellent aesthetics can be maintained.
