Description

  The invention of this application relates to a folded-plate roof structure used for the roof of buildings such as factories, warehouses, gymnasiums, etc., and more particularly, to an improved structure for attaching folded plates to a tight frame in the folded-panel roof structure. Is.

  Conventionally, for example, in a large-capacity, large-area building such as a factory, a warehouse, or a gymnasium, a roof member made of a steel plate generally called a folded plate has been used. This folded plate is lightweight, high in strength, easy in shape processing and construction, and has become a standard roof member for those buildings.

  In such a roof structure with a folded plate, generally, a tight frame bent in a cross-sectional mountain shape (trapezoidal shape) for attaching a folded plate is welded and fixed onto a beam member of the building, and a mountain shape portion (trapezoidal shape) of the tight frame is attached. Folded plate mounting structure for fixing a goby type folded plate to the part) via a hanging member has been adopted.

  As an example of this, for example, a suspension member having a saddle type single plate structure is erected at the center of the top surface of the chevron portion of the tight frame, and either the left or right horizontal direction ( A locking piece bent at a right angle is provided, and an engaging edge (an engaging edge bent into a U-shaped cross section, etc.) of an adjacent folded plate of a goby structure on the left and right sides is provided on the locking piece portion. There is known an engagement type attachment structure in which a folded plate is engaged with a tight frame by caulking in a state of being engaged with each other (see, for example, the configuration of Patent Document 1).

However, in the case of such a configuration, in order to use the hanging member, a hanging member installation work (installation work of the hanging member with a bolt and nut) for standing the hanging member on the tight frame is necessary. Moreover, since it is necessary to securely engage the engagement edge portions of the left and right folded plates with the upper end side engagement piece portion of the hanging member, it takes time and labor.
In addition, in the case of the same configuration, the folded plate has a single plate structure hanging member erected on the upper surface of the chevron portion of the tight frame, and a part of the upper end side is horizontally (right-angled) on either the left or right ) Since it is merely engaged and locked to the bent locking piece, the suspension strength is insufficient, bending deformation (buckling) is likely to occur, and the dynamic wind pressure strength against typhoons and the like is weak.

For this reason, some of the left and right sides of the chevron portion of the tight frame are provided with upper and lower two-tiered engaging claws (cut-and-raised pieces), while the left and right sides of the folded plate of the goby type structure to be attached. The upper and lower two-tiered engagement recesses (molding stepped portions) that engage with the same engaging claws are provided on both sides. By fitting a folded plate having an engaging recess (molded step) and pressing it from above, the folded plate has left and right double-sided engaging claws on both the left and right sides of the tight frame chevron. There is also provided a folding plate attachment structure of a suspensionless fitting type in which the engagement concave portion of the two-stage structure on the side is smoothly fitted and attached in a sliding state from above.

According to such a fitting type folded plate mounting structure, the hanging member as described above is not used, so the number of parts is reduced and the troublesome hanging work is not required, and the construction work is facilitated. Become.
Moreover, after fitting, the two-stage engagement recesses provided on the left and right sides of each folded plate are engaged with the upper and lower two-stage engagement claws provided on the left and right sides of the tight frame chevron. Therefore, the attachment strength to the tight frame is improved, and the dynamic wind pressure strength against typhoons and the like is increased.

JP-A-5-272199 (see paragraph [0002] of the specification and FIG. 5)

  In the case of the attachment structure of the above-described suspensionless fitting method, the tight frame and the folded plate are directly engaged and the number of engaging portions is increased, so that the mutual coupling strength is increased. In addition, since the hanging member is not used, the working of the hanging member is unnecessary, and the engagement concave portion of the folded plate is fitted from the upper side to the engagement claw of the tight frame, and is engaged by pressing downward. Therefore, construction work becomes easy.

  However, in the case of the same configuration, although the engagement is easy, at least the engagement structure of the engagement edges of the folded plates of the goby structure is, for example, an engagement processed into a U-shape. It is necessary to engage the edges together with a good seal and then fit onto the tight frame. Never fit each folded plate straight from top to bottom (vertical direction), and then step on the whole. Is not easy to fit.

  Further, a part of the tight frame is cut and raised to form the upper and lower two-stage engaging claws. Therefore, notch holes are formed in each tight frame, and the strength is lowered, and there is a drawback that buckling deformation tends to occur.

In addition, since there is no hanging member, there is no jig function for temporarily engaging the engaging edges on both sides of the folded plate when engaging the edges of the adjacent folded plates, and between tight frames. When the distance is large and the length of the folded plate is long, there is a big problem that accurate edge-to-edge engagement and connection cannot be performed. Therefore, a lot of manpower is required, and work efficiency during construction is poor.
Compared with the case where a suspension member is provided and the engagement edges on both sides of the folded plate are engaged on the upper end side of the suspension member, the water depth of the folded plate engagement edge is prevented in order to prevent intrusion of rainwater and the like. The height needs to be high and special care must be taken to maintain the sealing function.
The invention of this application was made in order to solve such a problem. By using a suspension member, the structure of the suspension member itself and the engagement structure of the engagement edge portion of the folded plate are improved. In addition to effectively improving the attachment strength between the folded plate and the tight frame, it is also possible to engage the hanging member with the hanging member or between the folded plates simply by stepping the folded plate straight from the top to the bottom with respect to the tight frame. It is an object of the present invention to provide a fitting type folded plate roof structure that can be easily and surely fitted together including a portion.

In order to solve the above-described problems, the invention of this application includes the following problem solving means.
(1) Problem Solving Means of Invention of Claim 1 In the problem solving means of the present invention, a tight frame having a chevron portion fixed to a building side, a suspension member fixed to the chevron portion of the tight frame, both sides And the adjacent engagement edges are engaged with each other, and a goby-type folded plate attached to the tight frame via the hanging member. Folded-plate roof structure, the engagement edges of the folded plates that are engaged with each other are elastically deformed from one side to the other and fitted from the upper side to the lower side The hanging member is attached to both sides of the chevron portion of the tight frame, and the upper portion has a desired height from the upper surface of the chevron portion of the tight frame. Standing upward, the rising part A fitting locking part for fitting and locking the engagement edge of the folded plate cap type structure is provided at the end, and the fitting locking part is an engagement edge of the folded plate cap type structure After fitting, the left and right pieces of the folded plate are elastically deformed in the expanding direction and fitted to the left and right fitting guide surfaces consisting of tapered surfaces. It is characterized by having both left and right locking portions for locking and fixing both the left and right pieces of the edge portion.
In the case of such a configuration, the engaging edge portions of the adjacent folded plates that are engaged with each other first are elastically deformed from one side to the other side and fitted from the upper side to the lower side. Since the cap-type structure is formed, the mutual engagement is made by elastically expanding the one on the other side downward and the other on the other side elastically expanding from the upper side to the lower side. It can be easily engaged if fitted, and the engaged state after the fitting also becomes stable with elastic pressures in opposite directions to each other. In addition, reliable engagement is significantly facilitated.
On the other hand, since the lower part of the suspension member is fixed and firmly fixed over both sides of the chevron portion of the tight frame, the suspension member itself supporting the folded plate is strong. It becomes a support structure. As a result, the engagement locking portion that engages and locks the engagement edge portion of the folded plate formed on the upper end portion of the suspension member is also formed with a stable support strength.
Further, the fitting engagement portion at the upper end of the suspension member that has the same stable support strength and rises up to a desired height is an engagement edge portion of the cap-type structure (specifically, the folded plates are engaged with each other). When the left and right pieces of the lower engagement edge (first fitting) are fitted to the fitting locking portion, first, elastic deformation is performed so that the distance between the upper side and the lower side first increases. While having a fitting guide surface on both the left and right sides composed of descending inclined surfaces that are smoothly guided and fitted from the upper side to the lower side, the fitted folded plate The left and right side locking portions are provided to securely lock and fix the right and left pieces of the engaging edge of the cap type structure so that they cannot be separated.
The fitting guide surfaces and the locking portions on both the left and right sides are integrated by, for example, joining the middle parts of the two suspension pieces to each other, and the upper end sides thereof are folded left and right in an inverted V shape. The bent piece (arrow piece) may have a cross-sectional arrow structure, and the upper side of the bent piece (arrow piece) may be configured as a fitting guide surface and the lower end side as a locking portion. Bending may be performed so that the left and right upper surfaces are configured as guide surfaces for fitting and the lower left and right sides are configured as locking portions.
In the case of such a configuration, the engagement edge portion located below the engagement edge portion of the cap-type structure that engages the adjacent folded plates with each other is attached to the tight frame. In addition, the fitting engagement portion on the upper end side of the hanging member is fitted smoothly and straightly from the upper side to the lower side with elastic deformation, and is engaged with each other after the fitting. It is securely locked in the state and cannot be separated. Accordingly, the engaging edge located on the upper side of the engaging edges of the cap-type structure that engages with each other of the adjacent folded plates fitted thereon is also on the lower side. It is fitted and locked to the fitting locking portion on the hanging member side in the same manner through the engaging edge of the cap-type structure of the folded plate.
Therefore, when the folded plate mounting structure having the same configuration is employed, the engagement members of the cap-type structure of the adjacent folded plates among the plurality of folded plates arranged in parallel between the tight frames are connected to each other by the above suspension member. It is located at the upper part of the mating locking part of the cap, and when it is stepped on from top to bottom while being overlapped up and down, the bottom of the engaging edge of the cap type structure Is fitted and locked to the above-described suspension member-side fitting locking portion, and further, the upper folded plate cap-type structure engaging edge is fitted with elastic deformation on it. The engagement edge portions of the adjacent folded plates are finally connected to each other in a state where they are securely overlapped and locked over the entire longitudinal direction.
Therefore, in the case of the above configuration, basically, a large number of folded plates are arranged in parallel between the chevron portions of the tight frame, and the engaging edges on both sides of the folded plates are arranged on the fitting locking portion of the hanging member. (Specifically, place the lower one first) and then step on the overlapping parts of the engaging edges on both sides of each folded plate from top to bottom sequentially. A large number of folded plates can be relatively easily fitted and locked to the fitting locking part of the hanging frame member on the tight frame side, and can be temporarily fixed when the folded plate is engaged by the hanging frame member. Thus, the construction work becomes very easy.
In addition, the folded plate that has been fitted and locked is securely locked by the locking function of the fitting locking portion for folding and engaging the folding plate engaging edge of the hanging member. Even if only the fitting locking portion is locked, the mounting strength is sufficiently high.
In addition, the folding plate engaging edge fitting locking portion for locking and engaging the suspension member is located on the upper surface of the chevron portion of the tight frame and is at a desired height above Further, the engaging edge portion on the folded plate side to be fitted is formed into a cap-type structure. Therefore, the desired water depth can be obtained, and the sealing function at the engaging edge is high, and there is no fear of rainwater intrusion or the like.
(2) Problem-solving means of the invention of claim 2 The problem-solving means of the invention is the construction of the problem-solving means of the invention of claim 1, wherein the both sides of the hanging member and the both sides of the folded plate are An engaging portion having a stepped structure that engages with each other when the folded plate is fitted and locked is provided.

  According to such a configuration, in addition to the engagement at the engagement portion of the folded plate edge described above, the engagement at the engagement portions on both sides of the suspension member and both sides of the folded plate is performed at three locations. Since the folded plates are engaged, the strength of attaching the folded plates to the tight frame is greatly improved, and the dynamic wind pressure strength against typhoons and the like is also increased.

  In addition, the engagement between these engagement portions can be easily engaged just by stepping the engagement portion downward from above, as in the case of fitting and locking of the engagement edge portion of the folded plate. Can be combined.

  As a result of the above, according to the invention of this application, it is possible to effectively improve the attachment strength of the folded plate to the tight frame while using the hanging member, and at the time of attachment, the folded plate is positioned above the tight frame. By simply stepping straight down from the top, the entire folded plate can be easily fitted and locked, including the engaging portion with the suspension member and the engaging portion between the folded plates. It is possible to provide a mated folded-plate roof structure.

<Modification>
In the configuration in the above embodiment, the second engagement portion 31f on the side of the hanging member 3 that engages and fixes the engagement edges 41d and 41d of the cap structure on both sides of the folded plate 4 and 4 is secured. Are combined in a state where they are opposed to each other on the trapezoidal portion of the tight frame 1, and the lower flat portions 31 a and 31 a of the tight frame 1 are combined with each other. While fixing to both sides of the trapezoidal part, the upper end side standing parts 31d and 31d are made into a double wall by interlacing each other, and the upper end part of each of the standing parts 31d and 31d is bent outward. Accordingly, the inverted V-shaped folded plate 4 is formed on both the left and right sides, and the engaging edge portions 41d and 41d fixing portions (locking pieces) 31e and 31e on both sides are formed.
However, as shown in FIG. 4, for example, the upright portions 31d and 31d and the locking portions 31e and 31e are formed of a single continuous plate, and the cross section is formed above the upright portions 31d and 31d. The fitting guide portion having a triangular closed cross-sectional structure is configured, and the downward inclined surfaces G, G on both right and left sides thereof are used as slide guide surfaces for fitting, and the acute angle portions on the left and right sides on the lower end side of the guide surface are fitted. You may change into the structure used as the latching | locking parts 31e and 31e.

With such a configuration, the strength (support rigidity) of the engaging portion 31f on the hanging member 3 side is greatly improved, and locking after fitting by the locking portions 31e and 31e on the lower end side of the fitting guide portion. The force (locking strength) is greatly improved, and the entire engagement edge portions 41d and 41d in the overlapped state are fitted and supported by the entire fitting guide portion (the entire three surfaces) having a closed sectional structure with a triangular cross section. Therefore, the attached state of the folded plates 4 and 4 becomes more stable, and there is no backlash.
Moreover, since the fitting guide portion has stable downward inclined surfaces G and G having a large inclination angle and no elastic deformation on both the left and right sides thereof, the fitting when the folded plates 4 and 4 are fitted is provided. The guide action in the mating direction becomes smoother, and the fitting operation of the folded plates 4 and 4 becomes smoother.

Further, in the case of the same configuration, compared to a case where a structure in which the lower portions of the pair of left and right hanging pieces 31, 31 are separately attached to the tight frame 1 and then the upper end side standing portions 31d, 31d are interlaced is adopted, The assembling work of the hanging member 3 becomes much easier. Of course, in the above-described embodiment, a hanging structure in which the upright portions 31d and 31d are joined and integrated together by welding or the like is arbitrarily adopted in advance. In this case, at least the assembling operation itself is the same as that of the modified example. Although it is almost as easy as the case, it requires more man-hours than this modification in that it requires prior welding or the like.
Furthermore, since the fitting guide portion has a triangular closed cross-sectional structure as described above, it is possible to completely block intrusion of rainwater and the like.
In the case of the configuration of this modified example, as a material of the above-described suspension member, for example, an aluminum material can be adopted in addition to a normal steel material.
