Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an outer wall structure which can be attached to a steel frame building such as a factory or a warehouse by a fitting method without forming a screw hole or the like on a steel plate outer wall forming plate which is bent and processed into a predetermined sectional shape.

[0002]

[Prior art]

 In steel-framed buildings such as factories and warehouses, a structure in which a so-called corrugated steel plate is fixed to a structural material such as a furring strip by hook bolts has been adopted as an outer wall, but in recent years, it is made of a steel plate bent into a predetermined cross-sectional shape. Outer wall forming plates are also often used.

First, as an example thereof, an “outer body” described in Japanese Utility Model Laid-Open No. 4-79115 will be described with reference to FIGS. 9 and 10. FIG. 9 is a perspective view showing an enclosure in which the device described in this publication is constructed, FIG. 10 is a sectional view, 91 is a building board, 92 is a retainer, 93 is a cap material, 94 is a screw, and 95 is a structural material. Is. Two adjacent construction boards 91a and 91b are arranged close to the structural material 95, and the convex strip called the rising side of the edge is fitted to the fixed bent portion of the pressing member 92 to construct the structural material. 95 is fixed with a screw 94, a cap material 93 is fitted into a gap between the two building plates 91a and 91b to close the gap between the building plates, and at the same time hide the presser member 92 and the screw 94, It has a flat appearance on the wall and at the joints.

Next, referring to FIG. 11, the “mounting structure for vertically attached siding” described in Japanese Utility Model Laid-Open No. 5-38165 will be described. The same symbols are used. The first building board 91a is fixed to the structural material 95 at the ends by screws 94, and then the ends of the second building board 91b are fitted to the ends of the first building board 91a. Fix it. At this time, the end portion of the second building board 91b is shaped so as to cover the head of the screw 94, so that the number of members is small, the construction is easy, and a mounting structure having a good appearance is realized.

By the way, each of these outer wall structures does not have many bolt holes on the wall surface as in the case of the conventional corrugated steel sheet, and has excellent appearance and waterproof performance without water leakage or corrosion from the hole portions. Although it was invented as a thing, as is clear from FIGS. 9 to 11, although it is concealed for a while, a gap or a mounting bolt hole between the building plates 91 constituting the outer wall remains, It is not a complete solution to the above objectives.

Further, there is a problem in that the construction efficiency is poor because the building board 91 must be sequentially attached from one direction at the time of construction.

[0007]

[Problems to be solved by the device]

 The present invention solves these problems and uses a molded plate that forms the outer wall with no joint gaps or bolt holes. The objective is to realize a fitting-mountable outer wall structure that is possible and has good construction efficiency.

[0008]

[Means for Solving the Problems]

 The present invention according to claim 1 is characterized in that the constricted portion of each convex portion of the outer wall forming plate is formed by continuously forming the convex portion having a constricted portion in the vicinity of the center of both side faces at predetermined intervals in the longitudinal direction. This is a fitting-mounting type outer wall structure in which the hanger attached to the above is clamped and fixed from the outside of the ridge by the tip-turning portion of the hanger fitting provided corresponding to the predetermined interval.

Further, according to the present invention as set forth in claim 2, an outer wall forming plate is formed by vertically forming continuous ridges having a constricted portion in the vicinity of the center of both side faces at predetermined intervals in the longitudinal direction. The ridges in the vicinity are overlapped and connected in the lateral direction, and the constricted part of each ridge is attached to the hanger attached to the structure at the end of the hook fitting provided at the predetermined interval. It is a fitting-mounted outer wall structure that is clamped and fixed from the outside of the ridge by the folded portion.

[0010]

[Work]

 According to the present invention, the molded plate forming the outer wall is fixed to the structural material by engagement of the ridge and the suspension, rather than the bolts and screws, and the outer wall molded plate is mutually attached at the ridge. Since they are overlapped, there is no gap or screw hole, or intrusion of air or water in the overlapped part, and the shape of the end part in the overlapped part does not have the upper and lower restrictions. It can be installed in any order for convenience of construction regardless of the external wall material installation procedure, improving efficiency.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view of the outer wall structure of the present invention showing a state immediately before mounting and a state after mounting, 1 is an outer wall forming plate, 2 is a hook metal fitting, 3 is a hook, 4 is a screw, 5 is a Furry, 6 is a pillar.

The outer wall forming plate 1 of the present invention is made by bending a thin coated steel plate, and the ridges 11 having a constricted portion 12 near the center of both side surfaces are continuously formed at regular intervals in the vertical direction (direction perpendicular to the paper surface). Is forming. On the other hand, a belt-shaped hanger 3 is attached to the furring strip 5 with a screw 4, and the hanger 3 has a pair of hanger metal fittings 2, 2 having an inverted V-shaped folded-back portion 21 inside. Are attached at predetermined intervals, that is, at intervals corresponding to the ridges 11 of the outer wall forming plate 1. When the outer wall forming plate 1 is pressed against the hanger 3 as indicated by the arrow in FIG. 1, the hanger fitting 2 opens as shown by the broken line in FIG. 2, and the hanger fitting is opened when the ridge 11 passes. By returning 2 to the original shape, the constricted portion 12 of the ridge 11 and the folded portion 21 of the suspension fitting 2 are engaged with each other, and the outer wall forming plate 1 is fixed to the furring strip 5 as shown in FIG.

The dimensions of this embodiment are as follows: the thickness of the outer wall forming plate 1 is 0.4 to 0.6 mm, the height of the ridge 11 is 20 mm, the width of the skirt portion is 20 mm, and the width of the constricted portion 12 is 22 mm and 29 mm. The interval between the ridges 11 is 180 mm, the lateral length of the outer wall forming plate 1 is 720 mm, and the longitudinal length is indefinite (arbitrary). FIG. 3 is a cross-sectional view showing a mounting state of a joint portion between two adjacent outer wall forming plates 1a and 1b. As shown in FIG. 3 (a), assuming that the left outer wall forming plate 1a is first attached to the hanger fitting 2, the left outer wall forming plate 1a is overlaid on the ridge 11a at the right end portion of the outer wall forming plate 1a, as shown in FIG. As shown in (b), the left end ridge 11b of the outer wall forming plate 1b is fitted. The ridge 11 formed at the end of the outer wall forming plate 1 is completely formed with the ridge 11a like the ridge 11a of the outer wall forming plate 1a in this figure, and a flat portion is partly attached to the tip. It is convenient to have different shapes on both sides of one outer wall forming plate, and one with a plate material only up to the middle of the protruding line 11b as shown by the protruding line 11b of the outer wall forming plate 1b. . When two adjacent outer wall forming plates 1a and 1b are overlapped, if different shapes are combined, two plates are formed at one ridge, as shown in Fig. 3 (b). In other words, since the five bends are shared while overlapping, it is possible to completely block the intrusion of air and rain from the overlapping parts of the plates due to the capillary phenomenon such as "leakage" in the roof. Further, in the example of FIG. 3, there is no problem even if the relationship between the upper and lower outer wall forming plates is reversed, so that there is no restriction on the mounting order of the outer wall forming plates in the outer wall structure of the present invention.

FIG. 4 is a perspective view of the outer wall showing a state where the outer wall forming plate of the present invention is being attached. First, as shown in FIG. 4 (a), a screw 4 is attached to the furring strip 5 which is a horizontal structure. Attach the suspension 3 with. You may nail it instead of screwing. Since the suspension fittings 2 are attached to the suspension 3 in advance at predetermined intervals, that is, at the intervals of the ridges 11 of the outer wall forming plate 1, so that the vertical positions of the suspension fittings 2 at each stage are aligned. warn. Then, the outer wall forming plate 1 is sequentially attached from the part having no trouble as shown in FIG. 4 (b).

5 to 8 show examples of different shapes of the suspension fitting 2. In FIG. 5, a pair of hanger fittings 2 and 2 are formed by attaching the same material in opposite directions. The angle θ formed by the folded-back portion 21 is 30 to 60 ° common to the following examples. Spot welding is recommended for attachment to the suspension 3. The position is indicated by reference numeral 22. In FIG. 6, the pair of suspension metal fittings 2 and 2 are formed by processing one material into a U-shape. In this way, the distance between the pair of hanger fittings 2 and 2 is determined at the time of processing, so that no error occurs due to mounting.

Further, in this example, the folded-back portion 21 is formed in two places. In this way, even if the suspension metal fitting 2 is attached to a certain degree, it can be fixed by engaging at least one of the two positions such as upper left and lower right or lower left and upper right. In the case of FIG. 7, ribs 23 are processed on the rising portions of the hook fittings 2 and 2 of FIG. In this way, a slightly large force is required for mounting the outer wall forming plate, but the detachment resistance after mounting increases, which is preferable.

In FIG. 8, ribs 23 are processed on the rising portions of the hook fittings 2 and 2 of FIG.
