[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sloped steel universal frame used for constructing structures such as earth retaining walls, retaining walls, seawalls, erosion control dams, weir pits having slopes, and a method of assembling the frame.

[0002]

2. Description of the Related Art FIGS. 9 and 10 show a construction state when constructing a structure such as a weir, for example, using a steel free frame 1. As shown in the figure, after excavating the construction site of the weir, etc., the pillar material 2, depth beam 3, lateral beam 4, screen material 5, brace 6
By assembling the steel universal frame 1, and if necessary, a plurality of steel universal frames 1 are continuously arranged in the front-rear direction (left-right direction in FIG. 9).
A plurality of columns are stacked on top of each other, and a plurality of columns are arranged in the lateral direction (in the left-right direction in FIG. 10) to construct a building frame 7 ', in which case the pillar material 2 at the boundary between adjacent steel movable frames 1 is shared, The structure frame 7'is filled with a filling material 8 such as a stone having a size that does not pass through the gap between the screen materials 5, and a lid screen material (not shown) is attached to the upper surface of the uppermost steel flexible frame 1. ，
The excavated part is backfilled with earth and sand to construct a structure 7 such as a weir. The screen material 5 is provided on the outermost peripheral side surface of the building frame 7 ', and the bottom screen material is provided on the bottom surface of the lowermost steel movable frame 1.

When the above-mentioned structure 7 has an inclined surface, that is, a slope A as shown in the figure, the steel universal frame 1 located on this slope A has its front surface aligned with the angle of the slope A as shown. Incline. As shown in FIG. 11, the framework of the steel universal frame 1 with the slope includes, for example, a vertical column member 21 on the rear side, an inclined column member 22 on the front side, and a depth beam 31 on the upper side. , The brace 6 and the trapezoidal frame 11 are formed, and the trapezoidal frames 11 are vertically arranged with two spaces left and right, and the trapezoidal frames 11 are formed by the upper and lower horizontal beams 41 on the rear side and the upper and lower horizontal beams 42 on the front side. The hexahedron-shaped three-dimensional frame 12 is connected to each other, and the rear screen member 51 and the front screen member 52 are connected between the rear left and right pillar members 21 and between the front left and right pillar members 22, respectively. It is a structure. Each of the column members 21 and 22 is made of H-shaped steel. The skeleton of the steel universal frame 1 shown in FIG. 11 does not necessarily show the same one of the concrete steel universal frames shown in FIG.

By the way, the above-mentioned steel free frame 1 is shown in FIG.
As shown in Fig.7, when the lateral change (left-right direction) is caused by the change of the ground after the completion of construction, the lateral beams 41 and 42 can be naturally inclined to follow the inclination and can be displaced into a parallelogram shape when viewed from the front. It is necessary to displace the steel universal frame 1 in a tilted manner in the lateral direction, and it is also necessary to displace it in the parallelogram shape. It is connected to the pillar member 21 (or 22) so as to be vertically rotatable. In this case, as a structure for connecting the horizontal beam 41 to the vertical column member 21 on the rear side so as to be rotatable in the vertical direction, the horizontal beam 41 is simply connected to the column member 21 by a single horizontal bolt in the front-rear direction. Just enough. However, if the horizontal beam 42 is simply applied to the front slanted column member 22 and bolt-connected, the horizontal beam 42 may be twisted at the connecting portion when the horizontal beam 42 is rotated in the vertical direction and the member may be damaged. In order to connect the slanted column member 22 so as to be rotatable in the vertical direction, a special device is required.

Conventionally, as shown in FIG. 12, in order to connect the horizontal beam 42 to the column member 22 made of inclined H-section steel on the front side so as to be rotatable in the vertical direction, the column members 22 on the front side are opposed to each other. The pedestal 13 having a vertical surface is fixed to the inner surface of the flange 22a, and the end of the cross beam 42 is inserted between the pedestals 13 and is connected by bolts and nuts (Actual Publication 6).
1-26424). In addition, the front screen material 5
Also in No. 2, similarly to the above, a pedestal having a vertical surface was fixed to one side of the flange 22a of the column member 22 and connected to the vertical surface of the pedestal with bolts and nuts.

However, the column member 22 and the cross beam 4 shown in FIG.
In the connection structure with 2, the pedestal 13 is fixed to the column member 22 in order to form a vertical mounting surface for the horizontal beam 42. Therefore, the number of steps required for manufacturing the column member 22 is high and the cost is high. In addition, there is a restriction on the combination of the space size between the facing flanges 22a of the column member 22 and the width size of the cross beam 42.

Therefore, the present applicant, as shown in FIG. 13, adopts a connecting structure using a tapered washer 15 having a vertical surface by a taper adapted to the inclination of the column member 22 and having a circular hole 15a. did. In this case, the pillar material 2
The mounting plate 16 is fixed to the second web portion 22b, and the side of the cross beam 42 opposite to the tapered washer 15 side is fixed to the mounting plate 16 with a bolt. The front screen material 52 is also connected by using a tapered washer with a round hole having a vertical surface as described above. According to this method, since the component (the pedestal 13) is not fixedly mounted on the pillar member 22, the manufacture of the pillar member 22 is simplified, and there are few restrictions on the combination of the size of the pillar member 22 and the cross beam 42. .

[0008]

However, the connection method using the above-described tapered washer 15 with a round hole has some problems in workability on site. That is, when connecting the two members of the column member 22 and the cross beam 42 or the screen member 52, it is not easy to pass the bolt through the hole 15a of the small taper washer 15 which is the third separate component.
Workability is poor. In particular, when the lower horizontal beam 42 of the lowermost steel movable frame 1 is connected to the column member 22, the work is almost in contact with the ground and the workability is extremely poor.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a steel universal frame with a sloped surface and an assembling method thereof, which facilitates the assembling work.

[0010]

In addition, the flange of this pillar and the cross beam The screen material was connected by horizontal bolts in the front-rear direction with a tapered washer having a vertical surface that was vertical when it was applied to the inclined flange inner surface of the pillar material, and a notch for inserting the bolt. Is characterized by. In the above description, at least the front side pillar material is at least the rear side pillar material if the front and back are expressed in reverse, and is therefore synonymous with at least one of the front and rear pillar materials.

According to a third aspect of the present invention, the notch of the taper washer is opened in a direction perpendicular to the taper direction.

[0012]

[Operation] When assembling the steel frame with slopes described above, when connecting the depth beam, the horizontal beam, and the screen member to each column member, at least the left and right inclined column members and the flange inner surface side of this column member are connected. The connection with the cross beam or the screen material where the ends are arranged by bolts is done by temporary tightening,
Temporarily assemble the free steel frame. After that, the notch of the taper washer is fitted into the gap between the inner surface of the flange of the pillar and the cross beam or the screen of the temporarily tightened bolt, and then the temporarily tightened bolt is finally tightened.
As a result, the steel frame with slope is assembled. Since the cross beam or screen material is connected to the front slanted column member in contact with the vertical surface of the taper washer, it can be rotated in the vertical direction regardless of the slant of the column member, and the member is twisted. A stable structure with no risk of damage. Further, when connecting the column member and the cross beam or the screen member in the temporary assembly, it is not necessary to interpose a tapered washer with a round hole, which is a small part, so the work is easy.

According to the third aspect, the taper washer can be inserted laterally into the narrow space between the flanges of the pillar material having an H-shaped cross section, and the work of installing the taper washer is easy in terms of working space. Also, even when the taper washer is arranged so that the notch faces upward, the taper washer does not drop, and workability is also good in this respect.

And are connected as shown in FIGS. That is, a hole 42a is made in the flange 42b at the end of the groove-shaped cross beam 42, and a mounting plate 60 having a hole 60a is welded and fixed to the web portion 22b of the column member 22 so as to form a vertical surface. A gusset plate 61 composed of a plate material 61a that is applied to the flange 22a of the column member 22 and a plate material 61b that is butt welded and fixed to the flange member 22a of the column member 22 is welded and fixed to the bottom portion of the end beam of the column beam 22, and the flange 22a of the column member 22 and the gusset plate 61 is connected by a bolt 62 and a nut 63,
The flange 42b on one side of the horizontal beam 42 is attached to the flange 22a of the column member 22 with a taper washer 64 interposed between the bolt 6 and the bolt 6
5 and a nut 66, and the flange 42b on the other side of the horizontal beam 42 is connected to the mounting plate 60 by a bolt 67 and a nut 68. The tapered washer 64 forms a vertical surface when it comes into contact with the flange 22a of the column member 22, so that the horizontal beam 42 that comes into contact therewith is vertically rotatable. In this embodiment, the bolt 6
At 5, the gusset plate 61 is joined together with the column member 22 and the cross beam 42. The taper washer 64 is shown in FIG.
As shown in detail in (a) and (b), it has a notch 64a opened in a direction orthogonal to the taper direction,
The angle of the taper is such that a vertical surface is formed when the flange 22a of the slanted column member 22 is contacted.

The details of the connecting portion between the front side pillar member 22 and the front side screen member 52 will be described. As shown in FIGS. 3 and 4, a hole 22c is formed in the flange 22a of the pillar member 22.
A hole 52a is formed at the end of the screen member 52, and a taper washer 70 having the same taper angle as the above-mentioned taper washer 64 and having a lateral cutout 70a is interposed and connected by a bolt 71 and a nut 72. The taper washer 70 is provided on the flange 22 of the column member 22.
Since a vertical surface is formed when it contacts a, the screen material 52 that contacts this is rotatable in the vertical direction.

FIG. 5 shows the details of the vicinity of the connecting portion between the upper end portion of the front pillar member 22 and the lateral beam 42. The upper cross beam 42 has the same structure as the above on the front flange 22a of the pillar member 22,
That is, the tapered washer 64 with the notch 64a
Are connected via bolts 65 and nuts 66, and are also connected to the mounting plate 60 welded and fixed to the column member 22 by bolts 67 and nuts 68. Regarding the upper and lower boundary portions of the stacked steel flexible frames 1, the horizontal beams of either one of the steel flexible frames 1 can be omitted as shown. In addition, the brace 6 is a depth beam 31.
(Or 32) by welding and fixing the gusset plate 73 to the pillar member 22 (or 21) with bolts 74 and nuts 75.
And is connected to the gusset plate 73 with bolts 76 and nuts.

Further, the details of the connecting portion between the rear vertical column member 21 and the lower horizontal beam 41 or the depth beam 32 will be described.
As shown in FIG. 6, the flange 21a of the vertical column member 21
The gusset plate 77 welded and fixed to the depth beam 31 and the flange 41b on one side of the horizontal beam 41, and the bolt 78
The flange 41b on the opposite side of the horizontal beam 41 is simply connected to the flange 21a of the column member 21 with a bolt 80 and a nut 81. Since the flange 21a of the vertical column member 21 is a vertical surface, the horizontal beam 41 can be easily rotated in the vertical direction by simply connecting the bolts and nuts. Also, the rear pillar material 21
The screen member 51 and the screen member 51 are simply connected by bolts 82 and nuts 83 as shown in FIG. Thereby, the screen material 51 can be rotated in the vertical direction without difficulty.

When assembling the steel flexible frame 1 described above, the depth beams 31, 32, the transverse beams 41, 42, and
At the time of connecting the screen members 51 and 52, at least the left and right column members 21 and 22 and the horizontal beams 41 whose ends are arranged on the inner surface side of the flanges 21a and 22a of the column members 21 and 22,
42 or each bolt 65 with the screen material 51, 52,
The connection by 67, 71, 78, 80, 82 is performed by temporary tightening to temporarily assemble the hexahedron-shaped three-dimensional frame 12 including the screen materials 51, 52. Actually, all the column members 21 and 22 and the depth beams 31, 32, the lateral beams 41, 42, and the screen members 51, 52 at the time of temporary assembly are connected by bolts by temporary fastening. After that, regarding the bolts 65 and 71 that connect the horizontal beam 42 or the screen material 52 to the front side column member 22 among the temporarily tightened bolts,
The notch 64a of the tapered washer 64 is fitted in the gap between the inner surface of the flange 22a of the column member 22 and the horizontal beam 42 or the screen member 52. After that, all the temporary tightening bolts are finally tightened. As a result, the steel frame with slope is assembled. In the actual construction of the frame structure, the steel flexible frames 1 are not individually assembled, but the adjacent steel flexible frames 1 share a column member 21 or 22 with a cross beam or a depth. The beams are connected, and the steel universal frames 1 are sequentially installed.

In the assembling work of the steel universal frame 1 as described above, at the time of connecting the front slanted column member 22 and the horizontal beam 42 or the screen member 52 at the time of temporary assembly,
Since it is not necessary to interpose a tapered washer with a round hole, which is a small part, the work of connecting the members is extremely easy. Further, since the horizontal beam 42 or the screen member 52 connected to the slanted column member 22 is attached in contact with the tapered washer 64 or 70 having a vertical surface, it can be rotated in the vertical direction. Therefore, when the steel universal frame 1 is laterally inclined due to the fluctuation of the ground after the installation of the steel universal frame 1, or when the steel universal frame 1 is installed on the inclined ground with the inclination, Since the horizontal beam 42 can be easily deformed into a row quadrangle following the inclination, a stable structure is obtained in which there is no risk of damage due to the twisting force acting on the member.

Further, since the directions of the notches 64a and 70a of the taper washers 64 and 70 are perpendicular to the taper direction, the taper washers 64 and 70 are laterally arranged in a narrow space between the flanges of the column member 22 having an H-shaped cross section. Can be inserted from. Therefore, the work of mounting the tapered washers 64, 70 is easier in terms of work space than the case of fitting the taper washers 64, 70 on the bolts from above or below. Also, if the cutout is oriented in the same direction as the taper direction, the taper washer is arranged so that the cutout faces upward (that is, when it is arranged on the flange 22a on the outer side (left side in FIG. 5) of the column member 22). ), The taper washer easily falls, so workability is poor, but
If the notches 64a and 70a are provided orthogonally to the taper direction as described above, such inconvenience does not occur.

The pillar material according to the present invention is made of H by welding.
It may have a cross section. In short, it is sufficient if the cross beam or the screen material has an H-shaped cross section having a flange to which bolts can be connected. Further, in the embodiment, the column member 22, the horizontal beam 42, and the depth beam 32 to which the gusset plate 61 is fixed are connected together, but the depth beam 32 may be connected to the column member 22 separately from the horizontal beam 42. Further, when the steel free frame 1 has both slopes, that is, when the rear column member 21 is also inclined, the present invention is naturally applied to connect the cross beam or the screen member to the rear column member. can do.

[0023]

According to the steel frame with sloped surface and the assembling method thereof of the present invention, since the tapered washer with the notch is used, the tapered washer can be mounted after the temporary assembling. At the time of connecting the column and the cross beam or screen material at the time, it is not necessary to interpose a tapered washer with a round hole, which is a small part, so it is extremely easy to connect the members, and with a slope. The workability of assembling the steel flexible frame is improved. Also, due to the interposition of a tapered washer that forms a vertical surface when contacting the flange of the column material,
The cross beam or screen member connected to the pillar member is attached in contact with the vertical surface, and is therefore rotatable in the vertical direction. Therefore, when the steel universal frame is laterally tilted due to the fluctuation of the ground after the installation of the steel universal frame, or when the steel universal frame is installed on the sloping ground with an inclination, the inclination is followed. Since the horizontal beam can be deformed into a parallelogram, a stable structure is obtained in which there is no risk of damage due to the torsional force acting on the member.

According to the third aspect, since the direction of the notch is orthogonal to the taper direction, the taper washer can be inserted laterally into a narrow space between the flanges of the pillar material having an H-shaped cross section. It is easy to install the tapered washer spatially. Also, even when the taper washer is arranged so that the notch faces upward, the taper washer does not drop, and workability is also good in this respect.

According to the present invention, since the width size of the groove shape of the horizontal beam does not have to match the size of the H-shaped opposite flanges of the column member, the size of the column member and the horizontal beam are restricted. Less is.

According to the assembling method of the fifth aspect, it is possible to efficiently perform the assembling of the steel free frame of the present invention.
