Description

The present invention bends a corrugated steel plate material such as a large deck plate, keystone plate, or deck plate obtained by bending a structural rolled steel plate into a corrugated shape having a large section modulus with a desired curvature in a direction perpendicular to the corrugating direction, and is required. The present invention relates to an arch-like building structure that can be expanded by a number of connections.

In general, corrugated steel sheets bent into a corrugated sheet with a large section modulus along the longitudinal direction, such as large deck plates, keystone plates, and deck plates, are bent at a desired curvature in a direction perpendicular to the corrugated direction. The resulting arched building structure is known. Such a structure has sufficient strength because it is formed by bending a structural rolled steel sheet as a raw material into a corrugated shape, and it cannot withstand stress from above and from the side as well as a wall material. A column structure can be easily realized.

Therefore, it is widely used as a snow shelter, a buffer shelter, and various warehouses, factories, processing plants, and the like. In particular, it has necessary and sufficient requirements as a building structure in heavy snowfall areas and typhoon-prone areas. In addition, the standard of the large deck plate which is the corrugated steel plate material used here is determined by the Japanese Industrial Standard (JIS), and the height of the peak of corrugation is set to 100 mm, The width is 570 mm, and the effective width is 500 mm. Also, five types of wall thickness are defined in the range of 2.3 mm to 6.0 mm.

In Patent Document 1, a large deck plate bent at a predetermined curvature is mounted on a foundation so that the tip portions thereof are close to each other, and a curved plate-like joint having an uneven corrugation on the zenith portions of both deck plates. Are fixed by bolting. The curved plate-like joint having such a corrugated corrugated shape is formed by cutting a large deck plate into an appropriate length and bending it, and fixing bolt holes formed at the end of the deck plate standing from the foundation. Are provided at both ends and are sequentially tightened. The content is to improve the conventional technology in which connecting flange-like joints are individually welded to the upper end of a large deck plate standing on the foundation to simplify the machining process in the factory. An improved technique for the purpose is disclosed.

In addition, Patent Document 2 is provided with a plurality of trapezoidal waveforms along the longitudinal direction in the same manner as Patent Document 1, bent into a curved shape in a direction orthogonal to the corrugated direction, and a wall member erected on the foundation It discloses that the connecting members are overlapped on the top and bottom of the tip of the slab and are sequentially connected by through bolts, and a structure that increases the strength by adding a reinforcing corrugated plate inside the arch-like body is disclosed. . In the configurations disclosed in these documents, the large deck plate is usually formed with a predetermined standard dimension, so the depth dimension can be easily accommodated by increasing the number of corrugated steel sheets to be used. If the bending is performed with a predetermined curvature, the maximum value of the structure is naturally determined.

If the structure of the standard dimension uses the material as it is, and a small structure smaller than that is required, the purpose can be achieved by cutting the corrugated steel sheet of the standard dimension. A large structure having a frontage is associated with various difficulties. For example, it is theoretically possible to connect members of standard dimensions in advance by joining such as welding, but considering that transportation from the factory to the construction site by road, railway, ship, etc. is required, This is unrealistic because there are transportation limitations due to various conditions such as trailers, wagons, tunnels, and cargo handling. However, in reality, this can be achieved with corrugated steel sheets of standard dimensions, such as large construction machinery hangars, large member storage or processing yard, large product processing / assembly factories, large processing facilities, etc. Not large structures may be required.

It is an object of the present invention to provide an arched building structure capable of arbitrarily expanding a frontage dimension by connecting a required number of constituent members obtained by bending a corrugated steel sheet having a standard dimension and a standard dimension or less.

The invention according to claim 1 is bent into a waveform having a large section modulus, is curved with a desired curvature in a direction orthogonal to the corrugation direction, and is mutually connected in the corrugation direction and the direction orthogonal to the corrugation direction. A pair of left and right corrugated steel sheet main members 14 and 24 forming a part of the arched structure by connecting, and the top part of the corrugated steel sheet main member bent into the same shape as the arch part of the arched structure At least one corrugated steel plate intermediate connecting member 16, 26, 26 ′ that is a member to be stretched and bent with a curvature matching the arch portion, the pair of left and right corrugated steel plate main members, and the at least one corrugated member. Joint members 18, 28, and 29 for mutually connecting opposite ends of the intermediate connecting member made of steel plate, and each opening of the corrugated steel plate main member and the corrugated steel plate intermediate connecting member. In the arch-like building structure that is sequentially fastened with the joint member interposed between the end portions, the joint members 18, 28, and 29 have the corrugated bent shape of the corrugated steel plate main member and the corrugated steel plate intermediate connecting member, and One end side bent into a waveform that fits so that there is no gap between the mutual joints in consideration of the thickness of each member, and a waveform that fits so that there is no gap between the mutual joints The arch-shaped building structure with an expandable frontage dimension configured as a stepped joint member formed so that the other end side bent into a step is shifted by a dimension that accepts the thickness of each member. It is characterized by being.

The invention according to claim 2 is characterized in that the corrugated steel plate intermediate connecting members 16, 26, 26 'are composed of two or more members connected and configured by the stepped joint members 18, 28, 29, respectively. It is an arch-shaped building structure that can be expanded in front dimension.

According to a third aspect of the present invention, the corrugated steel plate main member or the corrugated steel plate intermediate connection member is formed on the upper surface of the lower portion which is one end of the stepped joint members 18, 28, 29. Forming a corrugation having a size to receive the lower surface of the stepped joint member, and the lower surface of the upper portion, which is the other end of the stepped joint member, is either the corrugated steel plate intermediate connection member or the corrugated steel plate main member. It is an arch-like building structure capable of expanding the frontage dimension and having a waveform that is sized to accept the upper surface of the waveform without gaps.

An arched building structure having a configuration according to the present invention includes a corrugated steel sheet main member and an intermediate connecting member obtained by bending a corrugated steel sheet of standard dimensions using two, three, etc., stepped joints as described above. By sequentially fastening the open end portions, an arched building structure having an arbitrary frontage size can be assembled. In this case, the stepped joint is formed on the upper surface on one end side of the stepped joint member by forming a corrugation having a size that allows the corrugated steel plate main member or the corrugated steel plate intermediate connection member to receive the corrugated lower surface without any gaps. On the lower surface on the other end side of the joint member, the upper surface of the corrugated steel plate intermediate connecting member or the corrugated steel plate main member is formed to have a size that can receive without any gap. Therefore, since an undesirable gap does not occur between the members in each connecting portion, it is possible to reliably prevent rain and freezing of intrusion moisture only by interposing a simple packing material.

Moreover, the adjustment of the frontage dimension can be appropriately changed by changing the length of the corrugated steel plate intermediate connecting member and further changing the number of corrugated steel plate intermediate connecting members. Such a frontage dimension can be expanded by predicting the maximum load of the member including the dead weight of the roof member and the snow and snow loads such as snow accumulation and freezing and determining the curvature of curvature.

In addition, it is possible to use only the same standard member as the corrugated steel plate main member corrugated and the steel plate intermediate connecting member, but particularly in a building structure with an enlarged frontage, In order to reduce weight, it may be desirable to use lighter rigid materials. Even in such a situation, the step joint according to the present invention welds a member bent by an individual press die corresponding to each member, and can cope with it without any trouble. The structure of the roof portion constituted by such a step joint is not only easy to be waterproofed (rain rain), but also can be expected to reduce the accumulation of fallen leaves and dust, the occurrence of residual snow, and the like.

Hereinafter, an embodiment of an arched building structure capable of expanding the frontage size according to the present invention will be disclosed with reference to the accompanying drawings. FIG. 1 is a front view schematically showing the basic configuration of an arched building structure according to the present invention. FIG. 1A shows an embodiment of an arched building structure 10 in which the frontage is expanded using one intermediate connecting member 16, and FIG. 1B shows two intermediate connecting members 26, 26 ′. The Example of the arch-shaped building structure 20 which further expanded the frontage by using is shown.

In FIG. 1 (A), one intermediate connecting member 16 is disposed between the upper ends of a pair of left and right corrugated steel plate main members 14 erected on a foundation 12 by foundation bolts, and each connecting end is connected to a stepped joint member. 18 are connected with each other. In this embodiment, by determining the size of the intermediate connecting member 16 in accordance with the desired frontage size, only the standard-size member 14 is used, and the frontage in the foundation 2 in the case of using a conventional joint that covers from above is used. The dimension W ₀ can be expanded to the frontage dimension W ₁ . The dimension of the intermediate connecting member 16 can be appropriately changed from the short length to the standard dimension of the corrugated steel sheet used in consideration of the application and location conditions.

FIG. 1 (B) shows the arched building structure 20 has a frontage dimension W ₂ which is further extended than the frontage dimension W ₁ shown in FIG. 1 (A). In FIG. 1 (B), two intermediate connecting members 26, 26 'are disposed on the upper end sides of a pair of left and right corrugated steel sheet main members 24 erected on a foundation 22 by foundation bolts, whereby the first respect frontage dimension W ₁ in basic 12 embodiment of can be extended to the frontage dimension W _2.

In this embodiment, the difference between the upper end of the pair of left and right corrugated steel plate main members 24 and the two left and right intermediate connecting members 26, 26 'is different in the same manner as in the first embodiment shown in FIG. The joint members 28 are connected to each other. And the connection of two right and left intermediate connection members 26 and 26 'is mutually connected by the step joint member 29 interposed in the top | zenith part. Accordingly, the frontage W ₂ can be expanded by ΔW further than the frontage size W ₁ in the embodiment of FIG. 1A, and an arched building structure having a more expanded frontage size as illustrated above is required. It can correspond to various uses.

In addition, the connection in the zenith part of two right-and-left intermediate | middle connection members 26 and 26 'is not restricted to what mutually connects using the above-mentioned joint member 29, but as shown in FIG. By disposing the curved plate joint 39 or the connecting flange joint disclosed above and below and fixing with a through bolt, the intermediate connecting members 26 and 26 'at the zenith can be connected to each other. In the arched building structure according to the present invention, even if the zenith portion is fixed by the curved plate joint 39, it is possible to achieve the objectives of waterproofing, accumulation of dust and the like, generation of residual snow, and the like. .

FIG. 2 is a plan view (A) and a front view (B) showing a basic configuration of a stepped joint member that plays an important role in the present invention. The stepped joint members 18, 28, 29 are formed so that a step corresponding to at least the thickness of the steel plate is formed in the central portion of the two members of the upper surface joint portion 18U on the left side and the lower surface joint portion 18D on the right side in FIG. They are integrated by a welded line 18C.

As used herein, the “upper surface joint portion” means a member having a receiving surface that fits the upper surface of the member to be connected, and the “lower surface joint portion” means a receiving surface that matches the lower surface of the member to be connected. It means what you have. Note that the lower surface joint portion 18D and the upper surface joint portion 18U are welded at an appropriate angle of about 0 to 10 degrees necessary for the form of the connection portion. The lower surface joint portion 18D is obtained by pressing a rolled structural steel plate so that the lower surface of the corrugated steel plate abutted on the upper surface side can be received without a gap. Further, the upper surface joint portion 18U is obtained by pressing a rolled structural steel plate into a shape capable of receiving the upper surface of the corrugated steel plate abutted on the lower surface side without any gap.

In such a configuration, press molds having different shapes are used when the bottom joint 18D and the top joint 18U are press-molded before welding. That is, in the press molding of the lower surface joint portion 18D, a press die having a shape corresponding to the lower surface of the corrugated steel sheet material is used so as to contact the upper surface, and conversely, in the press molding of the upper surface joint portion 18U, the corrugated steel sheet is used. Each press work is performed using a press die having a shape corresponding to the upper surface of the material so as to contact the lower surface. Therefore, even if both members are the same standard or standards having slightly different dimensions, they can be supported. Bolt holes 18H for fastening are formed on the respective surfaces.

3A is a cross-sectional view of the upper surface joint portion 18U in FIG. 2A, taken along the line XX ′, and FIG. 3B is a cross-sectional view of the lower surface joint portion 18D in FIG. It is Y 'arrow sectional drawing, and has shown the state which made each surface side oppose. Here, although the thin line which shows the bending part of a trough part and each peak part is shown between both figures, since both shapes differ, displacement of (alpha), (beta), (gamma), etc. has arisen.

As a result of such a displacement between the valleys and the peaks, the structural members made of corrugated steel sheets can be connected without applying an excessive load or deformation. A gap step corresponding to the thickness of the corrugated steel sheet material used by combining the joint surfaces of the bottom joint portion 18D and the left top joint portion 18U that have been pressed in this manner is provided, and a pair of corrugated steel sheets main By welding in a state where the angle generated between the member and the intermediate connecting member is shifted, the desired joint member 18, 28, 29 is formed.

In the case of the stepped joint member 29 used at the zenith when using a plurality of intermediate connecting members as shown in FIG. 1 (B), they are pressed into shapes suitable for the upper and lower surfaces of the intermediate connecting members 26 and 26 ', respectively. It is formed by welding the lower surface joint portion 18D and the upper surface joint portion 18U in a state in which both processed members are angularly displaced so as to have the desired curvature of the zenith portion. Further, when using three or more intermediate connecting members, welding may be performed with an angular displacement so as to obtain a curvature suitable for each connecting portion.

The corrugated steel plate main members 14 and 24 and the intermediate connecting members 16, 26 and 26 'shown here are connected to one another of the stepped joint members 18, 28 and 29 having an angle suitable for the curvature of the connecting portion. Further, a rubber packing, a plastic packing, a leather packing, a caulking material, an adhesive, etc., not shown, are appropriately selected and tightened with bolts and nuts while performing waterproofing treatment (raining). In the embodiment of the arched building structure as shown in FIG. 1 (A), the corrugated steel plate main members 14 on both sides are erected on the foundation 12, the intermediate connecting member 16 is lifted by a crane, and the joint members are stepped at the left and right connecting portions. It is sufficient to construct by sequentially interposing 18 and performing necessary processing such as rain closing.

In the embodiment of the arched building structure using a plurality of intermediate connecting members 26 and 26 ′ as shown in FIG. 1B, the corrugated steel sheet main members 24 on both sides are erected on the foundation 22, and then the intermediate connecting member 26. , 26 'may be assembled while being suspended by a crane, and finally assembled with a stepped joint member 29 interposed at the zenith. Further, on the ground, the intermediate coupling members 26 and 26 ′ are integrally connected by interposing a joint member 29 at the zenith portion in advance, and then the left and right lower ends of the members integrally connected by lifting with a crane and the corrugated steel plate main member 24. An arch-shaped building structure may be constructed by performing a connecting operation with both upper end portions of the two being joined with the joint member 28 being interposed.

The arched building structure according to the present invention includes a stepped joint having one end and the other end that are press-molded so as to conform to the corrugated shapes of the corrugated steel plate main member and the corrugated steel plate intermediate connecting member, respectively. By interposing the pair of left and right corrugated steel plate main members and the corrugated steel plate intermediate connecting member rationally, the frontage dimension can be arbitrarily expanded.

Therefore, according to the present invention, it is possible to construct an arched building structure having a desired frontage size from an arched building structure having a normal frontage size using a standard steel material having a standard size. Such arched building structures with expanded frontage dimensions are standard for large construction machinery storage, large member storage or processing facilities, large product processing and assembly factories, large-scale processing facilities, etc. Large arched building structures that cannot be achieved with corrugated members of dimensions can be easily constructed.
