Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base reinforcing plate used for a structure of a mating structure such as a descending ridge of a building, a trough or a wall entering corner, an exit corner, etc. The present invention relates to the used joint structure.

[0002]

[Prior Art and Problems to be Solved] Since there are many damages to buildings due to typhoons every year, the applicant who manufactures and sells roofing materials conducted an independent investigation into the cause of the accident. As a result, at least in the case of an accident involving the scattering of roofing materials, it was found that the majority of the damage was in the area where the general plane and other surfaces meet, that is, in the mating area such as the down wing. Then, it was confirmed that there is a structural or construction problem of a building as described below as a factor causing the accident at the joint portion.

That is, to explain this with reference to the drawings, as a roof structure, for example, as shown in FIG. 8 or FIG. 9, a base material 2 is laid on a steel frame 1 which constitutes a purlin of a building, In this structure, a roofing material 5 such as a roofing material is further placed on a rafter 3 arranged in the direction of the eaves via a base material 4.

In such a structure, since a large wind pressure acts on a general surface of the connecting portion represented by the down wing, the steel frame 1 as a base is provided along the ridge core as shown in FIG. It is necessary to fix the long steel base plate 6 on the top, otherwise, except for the surface material 5 and the base material 4 to be laid and fixed on it, those which are located on the steel frame 1, The portion facing the core (the portion indicated by the arrow a in FIG. 8) is in a cantilevered supporting state and becomes structurally fragile.

However, the provision of the steel-frame base plate 6 for such reinforcement is not necessary for the structural calculation of the steel frame itself, and the construction of the steel-frame base plate 6 is desired for the roof construction. Since it is out of roof construction in terms of cost calculation, some building companies are shy to avoid it, and in most cases it is not implemented. Also,
Since the steel-frame base plate 6 falls within the scope of steel-frame work such as purlins, it is difficult for a base contractor or a sheet metal manufacturer who is in charge of it to attach it due to technical reasons such as processing equipment, and it is actually performed. Absent.

On the other hand, as the required performances such as heat insulation, soundproofing, and fireproofing for buildings are increasing, the base material having the above performances is naturally used for the base structure of the roof or wall. The base layer between the steel frame base material 2 and the surface material 5 as shown has become thick and multi-layered to 40 to 100 mm or more. A self-drilling screw (screw) with a nominal diameter of φ5 is usually used as a fixture for fixing each member on the upper layer side through the base material 2 on the steel frame 1, but the workability of the screw itself, the fixing force, etc. From the relationship, the thickness of the base material 2 which can be fixed or held is
The limit is usually about 40 mm. If the thickness exceeds this, the nominal diameter φ including specifications corresponding to a thickness of 100 mm or more
Although the screw of No. 6 is used, the use of the long fixing tool has a disadvantage that workability at the site is significantly reduced. And
The thickening of the base material 2 itself causes problems that the fixing tends to be unstable, it is difficult to confirm the fixed state, and the fixing tends to become impossible irrespective of the improper operation. From these circumstances, fixed certainty,
In consideration of workability, the upper limit of the thickness of the underlayer should be about 50 to 60 mm for practical use, but in practice, a thick underlayer tends to be used for the reason described above. As a result, fixation becomes uncertain and causes an accident in the event of a disaster.

The present invention has been made for the purpose of solving the above-mentioned conventional problems, and can be easily applied to the connecting portion without requiring special equipment or skill, and the underlayer can be reliably fixed. The present invention provides a base reinforcing plate and a joint structure using the base reinforcing plate.

[0008]

In order to solve the above-mentioned problems, the first invention is a long base material which is arranged outside the base material of the lowermost layer in the base structure of the connecting part such as a down ridge. It is assumed that the reinforcing plate has a plurality of openings continuously formed at small intervals along the longitudinal direction at the center in the width direction.

The opening may be formed such that the end of the plate in the longitudinal direction of the plate has an outwardly convex mountain shape.

A second aspect of the present invention is to lay a base material such as a heat insulating material, a soundproof material or a fireproof material on a structural body such as a steel frame, and continuously lay it at a small interval along the longitudinal direction at the center portion in the width direction. The base reinforcing plate having a plurality of openings formed thereon is bent and attached on the base material in accordance with an angle formed between adjacent base surfaces, and then fixed to the structural body, and the base reinforcing plate is provided with a surface material or The upper layer member that constitutes the mating portion such as the support member and the upper layer base material is fixed.

[0011]

According to the base reinforcing plate, when the base reinforcing plate is bent along the center line corresponding to the ridge core, a plurality of openings are continuously provided in the central portion in the width direction of the plate at small intervals along the longitudinal direction. Therefore, the bending stress concentrates on the opening, and the bending can be easily performed. That is, the bending can be easily performed on site according to the angle of the mating portion without the need for factory equipment.

Further, the base reinforcing plate can be attached by a simple on-site work as described above, in other words, it can be attached by a person other than a steel frame contractor, for example, a base material construction contractor, a sheet metal contractor, a carpenter or the like. .

Further, since the base reinforcing plate has a simple structure as described above, it can be provided at low cost and is excellent in transportability and handleability.

On the other hand, since the surface material and other mating members can be fixed to the base reinforcing plate attached as described above, it is not necessary to depend on the deep steel frame base level for fixing, and workability and workability can be improved. The reliability of fixation can be increased.

Therefore, according to the base reinforcing plate and the structure of the connecting portion constructed by using the base reinforcing plate, the fixing strength of the surface material and other members for the connecting portion at the connecting portion is improved, so that the mounting due to a storm such as a typhoon. It is possible to reliably avoid damage to the parts.

As the base reinforcing plate, the shape of the end portion of the opening in the plate longitudinal direction is formed in a convex chevron outward, so that the bending stress can be concentrated more on the crest of the chevron. The bending center of the plate is more easily exposed and workability is also improved.

[0017]

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The parts corresponding to those in FIGS. 8 to 10 are designated by the same reference numerals.

1 to 4 show an embodiment of a base reinforcing plate according to the present invention. The base reinforcing plate 10 is made of, for example, an iron plate having a thickness of about 1.0 to 2.3 mm, a surface-treated steel plate such as plating, a stainless steel plate, or the like, and is continuously formed at a small interval along the longitudinal direction at the center portion in the width direction. Multiple openings in 1
1 is formed.

In addition to the circular shape shown in FIG. 1 and the oval shape along the longitudinal direction shown in FIG. 2, the opening 11 has a chevron shape in which both ends in the longitudinal direction are convex outward as shown in FIG. Various shapes such as formed ones are applicable.

These openings 11 are provided to allow the carpenter or sheet metal trader to manually adjust the angle of the ground plane as a site work without the need for a steel frame trader such as a factory press or a factory bender. That is, when the plate 10 is bent along the ridge core, bending stress concentrates on the opening 11, so that the bending work can be performed easily and accurately as shown in FIG. Become.

Particularly, in the case of the opening shape shown in FIG. 3, since the stress is largely concentrated on the peak-shaped portion of the opening 11, the labor required for the bending work is further reduced, and the bending work is further suppressed. Position accuracy is also improved.

FIG. 5 to FIG. 7 show an example in which a connecting portion structure using such a base reinforcing plate 10 is formed on a structural frame made of steel frame 1 or the like.

The base plate 10 is, as shown in FIG. 7, a rafter 3 and a base material (upper layer member) 4 laid thereon.
It is provided after being bent according to the angle of this joint portion in advance as described above so as to be located between the rafter 3 and the lower rafter 3 and the base material 2 through the fixing tool 12 such as a screw. 5 or 6 in which the base reinforcing plate 10 is fixed on the steel frame 1 in this manner, the base material 4 is laid on the base reinforcing plate 10 thus fixed. And
Base material 4 on the surface layer on the rafter 3 and the base reinforcing plate 10
Further, by laying a surface material 5 such as a roof plate from above, and fastening these to the base reinforcing plate 10 via the fixtures 13, the joint portion structure is completed.

As the base materials 2 to 4 laid on the structural body made of the steel frame 1 etc., ALC boards, wood cement boards, glass fiber boards, rock wool boards, resin foam boards such as urethane, and the like. And is used for the purpose of heat insulation, soundproofing, fireproofing, and simply as a field.

According to such an interface structure, as shown in FIG.
Alternatively, as shown in FIG. 6, since the base reinforcing plate 10 extends along the building core at the connecting portion, the end forming the connecting portion of the base material 4 and the surface material 5 (see FIG. 7) at this portion. The part is supported from the back surface side and is not in a cantilever state. Further, the base material 2 or the base material 4 and the surface material 5 are securely fixed to the steel frame 1 or the base reinforcing plate 10 via fixing tools 12 and 13 which are not so long. Therefore, sufficient strength is ensured in this mating portion to withstand strong wind and rain such as typhoons.

Although the steel base plate 6 (see FIG. 10) in the steel frame construction is not provided in the embodiment of FIG. 7,
This is because this type of base plate 6 is desired as a roof structure, but is not always provided. However, even when the steel frame base plate 6 is provided, the work of fixing the base reinforcing plate 10 to the plate 6 via the thick base material 2 is wide on both sides because they are on the same core. Therefore, there is no influence on the reliability of fixing, and there is no problem in terms of workability.

[0027]

As is apparent from the above description, the base reinforcing plate according to the first aspect of the present invention has a plurality of openings continuously formed at small intervals along the longitudinal direction at the center portion in the width direction. Therefore, it can be easily bent at the site according to the angle of the connecting part without requiring factory equipment.
It can be easily installed even if it is not a specialist in the steel industry.

Further, since the base reinforcing plate has a simple structure, it can be provided at a low cost and is excellent in transportability and handleability.

Furthermore, since a surface material and other connecting members can be fixed to this base reinforcing plate,
It is not necessary to rely on the deep steel foundation level for these fixations, and workability and reliability of fixation can be improved.

On the other hand, when the end portion shape of the opening in the plate longitudinal direction is formed as a convex mountain shape outwardly as the base reinforcing plate, bending stress can be concentrated more on the top of the mountain shape. It is possible to obtain the effect that the bending center of the plate is more easily exposed and the workability is improved.

Further, according to the second aspect of the present invention, there is provided a structure of a connecting portion in which a base material such as a heat insulating material, a soundproof material, a fireproof material is laid on a structural body such as a steel frame, and the base reinforcing plate is adjacent to the base material. After being bent and attached according to the angle formed by the mating base surface, it was fixed to the structural frame, and the base reinforcing plate was fixed to an upper layer member that constitutes a mating portion such as a surface material or a supporting member and an upper layer base material. As a result, based on the effect of the base reinforcement plate, sufficient strength is exerted at the fixed part of the surface material and other members for the connecting part at the connecting part, so it is possible to reliably avoid damage to the connecting part due to storms such as typhoons. The effect of being able to be obtained is obtained.
