Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a temporary roof that is installed so as not to be exposed to rain at a construction site, a composting site, or the like, or is installed for use as a simple warehouse or event venue.
[0002]
[Prior art]
In recent years, in order to prevent water pollution, a simple roof has been needed to prevent the compost from raining. In addition, it is required to cover the site with a temporary roof so that construction can be performed without being affected by weather conditions. There is also a demand for a simple and inexpensive roof that can be used for temporary warehouses and event venues.
[0003]
[Problems to be solved by the invention]
In order to answer such a request, there are the following proposals and products, but each has some problems.
That is, Japanese Patent Laid-Open No. 9-235781 discloses that end plates with through holes are fixed to both ends of an I-shaped steel to form columns, beams, vertical rails, etc., and seat plates with through holes at appropriate locations on these side surfaces. The I-shaped steel flange has a through-hole, and bolts are inserted into the end plate, seat plate, and flange through-holes to fasten and fasten the front and rear struts with braces with turnbuckles. An assembling-type temporary building is disclosed in which several roof boards made of corrugated plates are juxtaposed on a beam.
In this assembly-type temporary building, the roof is made of corrugated plates, so that the load is large and disadvantageous in design. In addition, if the span is large, it is necessary to increase the size of the beam, which is uneconomical. In addition, since it is necessary to weld columns and beams for manufacturing, the processing cost is high, and the cost of soaking plating after processing is high.
[0004]
In addition, in Japanese Patent Application Laid-Open No. 9-41674, a horizontal beam is spanned between main fences on both sides made of I-shaped steel to which an end plate is fixed, and a roof plate such as a corrugated plate is stretched on the horizontal beam, A seat piece is provided below the front end of the main fence to form front and rear roof pieces, and the end plates of the main fence are bolted together, and a T-shaped central support whose upper surface is chevron-shaped is below the junction of the main fence on both sides An assembly roofing board for a temporary building is disclosed in which the lower part of the T-shaped central support and the seat piece of the roof piece are connected by a wire.
In this assembled roofing board, a tora wire is required for mounting on the framework scaffold, which is disadvantageous when there is no room on the site. Moreover, since the tie bar (wire) is at the height of the eaves, the usable upper space is limited. Moreover, since it is necessary to weld in order to form a roof piece, a processing cost becomes high and the cost of the soaking plating becomes high.
[0005]
Japanese Patent Application Laid-Open No. 5-195633 discloses a mountain-shaped roof material made of a long aluminum alloy long mold material arranged in a predetermined number along a girder direction, and a hollow aluminum alloy material integrally joined to the roof material. It consists of a pillar made of a long material and a roof sheet stretched between the roof materials, and a retaining material provided at both ears of the roof sheet is slidably inserted into the guide groove opened in the roof material, In addition, a temporary roof is disclosed in which a roof sheet is stretched so as to be movable between roof materials, and a traveling member with a roller that moves by guiding rails provided on both sides of the work space is attached to the lower part of the column. Yes.
In this temporary roof, the material cost is high because the roofing material and the support are made of aluminum alloy. Also, since the tie bar is attached between the eaves, the upper space above it cannot be used. In addition, since the pillar is made of a hollow aluminum alloy long material, the strength is low and the eave height cannot be increased too much.
[0006]
In addition, tent warehouses or general steel warehouses are provided.
However, since the former is a steel pipe lattice structure, material cost and processing cost are high. The latter is a heavy steel structure, which requires a large amount of construction, and because it uses a lot of materials and welding, the cost is high, and the number of secondary members such as binders and purlins is large. It becomes complicated.
[0007]

[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing the overall configuration of the temporary roof according to the present embodiment. The temporary roof is constructed by arranging a plurality of portal unit frames F in parallel at equal intervals, and these are connected by a connecting material and braces. The interval between the frames F is set to about 2 m in accordance with the width of the sheet stretched on the roof. As a result, standard braces used for the framework scaffold can be used as they are.
[0019]
FIG. 2 is a front view showing the unit frame. The unit frame F includes columns 1 on both sides, beams 2 and 2 combined in a mountain shape, canes 3 and 3 and tie bars 4, and the columns 1 and beams 2 are made of H-section steel. For the column 1 and the beam 2, a welded light H-shaped steel or a light-weight grooved steel fixed back to back can be used, but the H-shaped steel and the welded H-shaped steel are more suitable than the latter. The cross-sectional performance is excellent. In addition, when high-strength light-weight H-section steel is used for the column 1 and the beam 2, since the section modulus is larger than that of the rolled H-section steel at the same weight, the overall steel weight is reduced, so that the material cost can be reduced. Since the weight of the member is light, the construction efficiency is improved. As a material, for example, a material equivalent to or higher than SM490A defined in JIS G3106 may be used.
[0020]
As described above, since the interval between the unit frames F is set narrowly in accordance with the width of the stretched roof / wall sheet, the roof / wall sheet can be directly attached to the column 1 and the beam 2. Members such as purlins and trunk edges are not required, and the load per unit frame can be reduced. In addition, light members (for example, braces for frame scaffolds) are used for the connecting material of the pillar 1 and the beam 2. be able to.
The cane 3 and the tie bar 4 are formed by fixing lightweight grooved steel with lips back to back. The tie bar 4 is attached to an intermediate portion of the beam 2 on the ridge side, and can thereby be used effectively up to a height indicated by a broken line in the drawing.
[0021]
FIG. 3 is a side view of the temporary roof. Each unit frame F is connected by a pillar connecting material 5A, and a girder brace 6 is installed. The girder brace 6 is attached to the indoor flange of the pillar 1. The column 1 may be installed on a concrete foundation, but it is preferable to place the column 1 on a base 11 made of H-shaped steel because accuracy is easily obtained.
[0022]
FIG. 4 is a plan view (roof plan) of the temporary roof. The roof surfaces are connected by an eaves connecting material 5B, a roof connecting material 5C, and a ridge connecting material 5D, and a roof brace 7 is installed. The roof brace 7 is attached to the indoor flange of the beam 2. The roof brace 7 is continuously disposed in the eaves portion and the rib portion (a portion adjacent to the wife surface) to counter the wind pressure, but may be omitted in other portions as appropriate. .
[0023]
FIG. 5 is a detailed view of the eaves part and the cane joint part. Each of the column 1 and the beam 2 has an H-shaped steel end portion cut obliquely, and these web end portions are sandwiched from both sides by a T-shaped splice plate 8 and joined by a high-strength bolt. The eaves-linking material 5B is joined to the central protrusion 8a of the splice plate 8.
In order to transmit the force of the roof brace 7 to the girder brace 6, it is desirable that the indoor flanges of the column 1 and the beam 2 are joined to each other with a high-strength bolt via a square-shaped joining member 12. However, since it is not necessary to transmit a bending moment at this column / beam joint, there is no need to connect the outdoor flange.
[0024]
The cane 3 is formed by combining two lightweight grooved steels with lips back to back and fixed integrally by a spelling material 13. Since the compressive force acts on the structural calculation, the resistance to buckling is strengthened. Both ends of the cane 3 are joined to the flange near the eaves of the column 1 and the flange near the eaves of the beam 2 with high-strength bolts via T-shaped joining members 14 and 14A. That is, the projecting portions of the joining members 14 and 14A are inserted between the back-to-back lip-shaped lightweight channel steels and bolted, and the flange portions of the joining members 14 and 14A are bolted to the flanges of the columns 1 and 2. Is done. L-shaped reinforcing members 15 are attached to the insides of the flanges of the pillar 1 and the beam 2 to which the cane 3 is attached for reinforcement.
[0025]
FIG. 6 is a detailed view of the ridge. In the beams 2 and 2, the end portions of the H-shaped steel are cut obliquely, the web end portions are sandwiched from both sides by a T-shaped splice plate 9, and are joined by high-strength bolts. An eaves-linking material 5D is joined to the central protrusion 9a of the splice plate 9.
[0026]
FIG. 7 is a detailed view of the tie bar joint. The tie bar 4 is formed by combining two lightweight channel steels with lips back to back and fixed integrally by a spelling material 16. There is no concern about buckling because the tie bar 4 only works on the structural calculation. However, a certain amount of compressive force is applied during assembly, and when a tie bar 4 is made of a wire or steel rod, it is resistant to compression. In addition, there is a problem in that there is a problem that the deflection is generated and the shape of the cabin is not determined. Therefore, it is preferable to use the member as described above.
[0027]
The closer the tie bar 4 is to the eave, the smaller the bending moment of the beam is. However, the length of the tie bar becomes too long and the handling at the site becomes difficult. In addition, the height of the usable indoor space is restricted. On the other hand, if the mounting position of the tie bar is too close to the building, the structural effect is reduced. Therefore, it is desirable to attach the both ends of the tie bar 4 at a position of about 1/4 to 3/4 from the ridge in the length between the ridge and the eave.
[0028]
Both ends of the tie bar 4 are joined to the flanges near the eaves of the beams 2 and 2 with a high-strength bolt via a T-shaped joining member 17. That is, the protruding portion of the joining member 17 is inserted between the back-to-back lightweight grooved steel and bolted, and the flange portion of the joining member 17 is bolted to the flange of the beam 2. An L-shaped reinforcing member 18 is attached to the inside of the flange of the beam 2 to which the tie bar 4 is attached for reinforcement.
[0029]
FIG. 8 is a detailed view of the connecting material joint and the brace joint. L-shaped joining members 19 are attached to the webs of the columns 1 and 2 by high-strength bolts at predetermined intervals. The plate thickness of the joining member 19 is set to be thicker than the web thickness of the column 1 and the beam 2 and is sandwiched by the joining members 19 and 19 from both sides over the entire height of the web. Even if it is not fixed, lateral buckling can be prevented.
[0030]
The connecting members 5A to 5D and the braces 6 and 7 are obtained by crushing both ends of a small-diameter steel pipe flatly to make a hole, and connecting them with a pin 20 at the center part, and the brace of a normal framework scaffold Is the same. Therefore, when a standard product for scaffolding is used for these connecting materials 5A to 5D and braces 6 and 7, costs can be significantly reduced. Since the connecting materials 5A to 5D and the braces 6 and 7 are lightweight, they can be easily carried by one person and are easy to construct. Furthermore, there is no need to adjust the length on-site like a round steel brace with a turnbuckle, and the shape of the entire shed is automatically set by bolting to the predetermined holes of the connecting materials 5A to 5D and braces 6 and 7. It will be decided.
The connecting members 5A to 5D are attached to the joining member 19 by bolts, and the girder brace 6 and the roof brace 7 are respectively attached directly to the holes opened in the flanges on the indoor side of the pillar 1 and the beam 2 by bolts.
[0031]
FIG. 9 is a detailed view of the seat mounting portion. As shown in FIG. 8 and FIG. 9, seat guides 21 having “C” -shaped seat fixing portions 21 a at both ends are fixed to the outdoor flanges of the pillar 1 and the beam 2 by guide fixing bolts 22. Yes. Since the interval between the unit frames F is set to be approximately equal to the width of the seat 23, the edge of the seat 23 is reinforced with a rope or the like to form the insertion portion 23a, and the insertion portion 23a of the seat 23 is fixed to the seat of the seat guide 21. A roof and a wall can be completed only by inserting in the part 21a.
