Description

  The present invention relates to a technique for joining a member mainly for reinforcement or earthquake resistance to a large pillar formed of steel or the like.

  Conventionally, a horizontal column or a diagonal member is attached to a large column or chimney formed of steel for seismic reinforcement and prevention of collapse. The attachment of the horizontal material or the diagonal material to the column is performed through a joint. As this joint, both the attachment side and the attachment side have a cruciform shape made of a gusset plate.

  FIG. 18 shows a state in which the horizontal member and the column member are fixed by a conventional cross joint. Gusset plates assembled in a cross shape are provided at the end of the horizontal member and the side surface of the column. After contacting the end of the gusset plate on the horizontal material side and the end of the gusset plate on the column side, both sides so as to connect the gusset plate on the horizontal material side and the gusset plate on the column side with a steel plate called a splice plate The horizontal member and the column member are joined by sandwiching them from each other, tightening them with bolts, or welding the gusset plate on the horizontal member side and the gusset plate on the column member side. In such a joining method, it is necessary to form the horizontal material gusset plate shorter than the column side gusset plate in consideration of construction accuracy.

  By the way, in the case of the conventional joining method, the length of the joined part becomes long, and the number of bolts in the joint part may increase. This makes positioning of the bolt holes more difficult and allows smooth positioning depending on the work environment (for example, high places where relatively strong winds blow, such as high-rise buildings and dam construction). It was difficult to perform, and the difficulty and cost of joining work increased.

  Further, in the conventional joining method, there is no place for temporarily placing the horizontal material and the diagonal material before joining, and therefore, it has been necessary to suspend them with a crane or the like until the joining work is completed.

  Furthermore, in the conventional joining method, the gusset positioning operation is performed in a state of being suspended by a crane, so that it is very difficult to perform positioning with high accuracy.

  Then, this invention makes it a subject to provide the joining structure of the structure which makes it possible to perform the joining operation | work of the steel pillar and steel material in a large sized structure simply and under high safety.

  Furthermore, this invention makes it a subject to provide the joining structure of the structure which makes it possible to reduce the expense required for the joining operation | work of the steel pillar and steel materials in a large sized structure.

  This invention is made | formed in view of the said matter, ie, this invention is a structure which joins the 2nd member which supports the 1st member to the 1st member used as the main axis | shaft of a structure, A first horizontal plate extending horizontally from the side of the member and a second horizontal plate extending horizontally from the second member main body, with the second horizontal plate stacked on the first horizontal plate, One member and the second member are joined.

INDUSTRIAL APPLICABILITY The present invention can be suitably used for attaching a steel pipe for supporting and reinforcing a relatively large structure such as a large steel tower, a bridge, or a large steel chimney. The first member in the present invention is a pillar material on the structure side, and the second member can be a stress material on the side that supports and reinforces the pillar material.

  And the 1st member which concerns on this invention has the 1st horizontal board | plate material provided horizontally from the side to the front, and the 2nd member was the 2nd horizontal board | plate material provided horizontally from the side or the surface ahead. have. For this reason, when attaching the second member to the first member, the second horizontal plate member of the second member can be once placed on the first horizontal plate member of the first member (so-called temporary fixing).

  Conventionally, when joining a 2nd member to a 1st member, the 2nd member was suspended with the crane etc., and it moved to the joining position with a 1st member, and joined work. For this reason, when a strong wind blows, the second member suspended from the crane is swayed by the wind, making it difficult to perform the alignment work at the joining position.

  However, according to this invention, a 2nd member can be temporarily mounted on the 1st horizontal board | plate material of a 1st member, and a joining position can be united from the state. In most cases, the first horizontal plate member and the second horizontal plate member are provided with bolt holes for inserting bolts for fixing both. According to the present invention, the second member can be temporarily placed on the first horizontal plate member, and therefore, it is possible to simplify the operation of aligning the bolt holes at a high place or when the wind is strong.

  Further, the first member according to the present invention has a first vertical plate material erected perpendicularly to the first horizontal plate material at the front end of the first horizontal plate material, and the first vertical plate material has its front end A first cut portion that is cut from the first end toward the base end, and the second horizontal plate member is positioned in the first cut portion so that the first member and the second member are joined. You can also.

  As this example, there can be mentioned a plate member made of two plate-like steel members formed in an inverted T shape, a plate-like second member, and the like.

  In addition, the first horizontal plate member according to the present invention further includes a second cut portion cut from the tip end toward the base end, and is provided at the tip end of the second horizontal plate member. The first member and the second member may be joined by positioning the second vertical plate material depending on the second notch in the second cut portion.

  This is a reverse of the inverted T-shaped first member formed by combining the two plates described above and the single plate-shaped second member (that is, an inverted T-shaped stress material and And a single plate-like pillar material).

  With these structures, the second member can be placed on the first horizontal plate, so that the joining operation can be simplified.

  Further, since the first member and the second member can be directly fixed, the first member and the second member can be joined without using a conventionally used splice plate. Thereby, the cost required for joining can be reduced.

  In addition, the first horizontal plate member and the first vertical plate member, and the second horizontal plate member and the second vertical plate member according to the present invention can be applied to those intersecting in a cross-shaped cross section. In other words, the present invention can be suitably used for the first member and the second member of steel members having a cross-shaped cross section.

  Thus, since the first member and the second member are brought into contact with each other by one-surface shearing, the screw length of the bolt can be shortened. Thereby, joining work will be simplified.

  Furthermore, since the first member and the second member can be directly joined, a splice plate is not necessary, and the operation cost can be reduced.

  Moreover, since the 2nd member can be mounted on a gusset plate when the 1st horizontal board | plate material provided in the 1st member side is made into a gusset plate, joining work can be simplified.

  In addition, in the vicinity of the deepest portion of the first cut portion or the deepest portion of the second cut portion according to the present invention, the first horizontal plate member inserted into the first cut portion or the second horizontal plate inserted into the second cut portion. It is preferable that a stopper for suppressing the movement of the plate material is provided. In addition, this stopper is installed in the position where a board | plate material does not reach the deepest part of a notch part. Therefore, the shape of the stopper is not limited, and may be, for example, a simple block-like lump or a clip shape. In any case, it is sufficient that the first vertical plate or the second horizontal plate does not enter the first cut portion or the second cut portion when the first member and the second member are joined. It may be removed at the end of.

  The vicinity of the deepest part of the first cut part or the deepest part of the second cut part is, for example, on the first vertical plate material provided with the first cut part or the first cut part provided with the second cut part. It can be on a horizontal plate.

  In this way, by suppressing the movement of the plate material in each cut portion, it is possible to reduce in advance the cause of the plate material entering the cut portion more than necessary and causing the steel material to deteriorate or crack. Thereby, it leads also to the improvement of durability and durability of a joined part.

  The present invention also includes a pair of parallel members, a first connection member that is vertically interposed between the parallel members, and connects the parallel members, and is provided in the first connection member and faces the longitudinal direction of the first connection member. A structure in which a first member having a joint plate, a pair of parallel members, and a second member having a second connecting member that is vertically interposed between the parallel members and connects the parallel members are joined at right angles. The parallel member and the second connecting member of the second member are provided with a cut portion cut in the longitudinal direction thereof, and a part of the parallel member of the first member is located in the cut portion. Thus, the first member and the second member may be joined by bringing the joint plate and the second connecting member into contact with each other.

  As an example, a case where two steel materials having a cross-sectional shape of H type (so-called H steel) are joined so as to form a right angle. Furthermore, it becomes possible by joining a 1st member and a 2nd member through a joint plate in this way so that two H steels may make a right angle.

  Also in this case, since the joint and the second member can be directly fixed, a splice plate dedicated for fixing becomes unnecessary, and the construction cost is reduced.

  In the case of such a structure, a stopper may be provided in order to reduce unnecessary movement of the plate material in each cut portion. In addition, it is preferable to install this stopper at a position where the plate material does not reach the deepest portion of the cut portion.

The present invention also includes a first member having a pair of parallel members, a first connecting member that is vertically interposed between the parallel members and connects the parallel members, a pair of parallel members, and a parallel relationship between them. A second member having a second connecting member that is vertically interposed between the members and connects the parallel members is coaxially joined to the first connecting member and the second connecting member in the longitudinal direction. A notched portion cut into the first connecting member, a part of the parallel member on the second member side is located in the notched portion of the first connecting member, and the parallel member on the first member side in the notched portion of the second connecting member It is good also as a structure by which a 1st member and a 2nd member are joined because one part is located. Even in this configuration, it is preferable to provide a stopper in the vicinity of the deepest portion of the cut portion to suppress unnecessary movement of the plate material in the cut.

  This can be exemplified by the case where two H steels are joined in the length direction. Also in this case, since the H steels can be directly joined without using a splice plate, the cost required for joining can be reduced.

  Moreover, when the two H steels are joined with a bolt, the screw length of the bolt can be shortened because the joining surface is sheared on one side. Thereby, the weight of the structure itself is reduced and the cost can be reduced.

  As described above, according to the present invention, there is provided a joint structure for a structure that enables a steel column and a steel material in a large structure to be joined easily and with high safety. It becomes possible.

  Furthermore, the present invention can provide a joint structure for a structure that can reduce the cost required for the work of joining a steel column and a steel material in a large structure.

  Hereinafter, the joint structure of the column material (first member) and the stress material (second member) of the structure in the present embodiment will be described in detail with reference to the drawings. In addition, the joining structure of this invention shall be applied to the structure of the joint of a large steel chimney, the structure which supports a steel tower, etc.

  In this embodiment, the column material and the stress material are cylindrical, and a case where the stress material is joined to the column material so as to form a right angle will be described.

(Constitution)
First, the structure of the column material and the stress material of this embodiment will be described.

  1 and 2 show a joining structure of a pillar material 1 of this embodiment and a stress material 2 that supports the pillar material 1. The column material 1 and the stress material 2 in this embodiment are cylindrical steel pipes, and hereinafter, the stress material 2 will be referred to as an attachment steel pipe.

  The pillar material 1 has a pillar-side cross gusset 3 formed on the side surface so that two plates intersect to form a cross-shaped cross section. The column-side cross gusset 3 is a column-side horizontal gusset plate (first horizontal plate material) 4 perpendicular to the axial direction of the column 1 and a column-side vertical gusset plate (vertical-side gusset plate 4 perpendicular to the column-side horizontal gusset plate 4). First vertical plate material) 5. The column side vertical gusset plate 5 is provided with bolt holes 6a, 6b, 6c, 6d for inserting bolts on the upper side and the lower side with the column side horizontal gusset plate 4 as a boundary.

  Further, as shown in FIG. 2, the column-side vertical gusset plate 5 is formed with a cut (hereinafter referred to as an upper cut-in portion) 7 above the column-side horizontal gusset plate 4. In addition, a stopper 8 is disposed on the column-side horizontal gusset plate 4 at a position corresponding to the deepest portion of the upper cut portion 7. The stopper 8 may be provided on at least one side with the pillar side horizontal gusset plate 4 as a boundary.

In addition, a steel pipe side cross gusset 9 formed by crossing two plates so as to form a cross-shaped cross section is also provided at the end of the mounting steel pipe 2. The steel pipe side cross gusset 9 is a steel pipe side horizontal gusset plate (second horizontal plate) 10 perpendicular to the axial direction of the mounting steel pipe 2, and a steel pipe side vertical gusset plate (vertical to the steel pipe side horizontal gusset plate 10 ( (Second vertical plate material) 11. Bolt holes 6a, 6b, 6c, and 6d for inserting bolts are provided on the steel pipe side vertical gusset plate 11 corresponding to the upper side and the lower side with the steel pipe side horizontal gusset plate 10 as a boundary so as to oppose each other.

  Further, the steel pipe side vertical gusset plate 11 is formed with a cut (hereinafter referred to as a lower cut portion) below the steel pipe side horizontal gusset plate 10.

  The above is the configuration of the column member 1 and the mounting steel pipe 2 of the present embodiment.

(About joining)
Next, the joining structure including the operation when joining the column member 1 and the mounting steel pipe 2 will be described. In addition, in order to attach the attachment steel pipe 2 to the column 1, the attachment steel pipe 2 is suspended by a crane (not shown) and moved to the joining position with the pillar 1.

  FIGS. 3 and 4 show a state before the column material 1 and the attachment steel pipe 2 are joined, and FIGS. 5 and 6 show a state after the column material 1 and the attachment steel pipe 2 are joined. In order to attach the mounting steel pipe 2 to the column 1, the steel pipe side horizontal gusset plate 10 on the mounting steel pipe 2 side is inserted into the upper notch 7 of the column 1 and the column on the column 1 side is inserted into the lower notch 12 of the mounting steel pipe 2. The mounting steel pipe 2 is moved so as to insert the side horizontal gusset plate 4 (the arrow X direction in FIG. 3 and the arrow Y direction in FIG. 4). That is, as shown in FIG. 7, the steel pipe side horizontal gusset plate 10 of the mounting steel pipe 2 is placed on the column side horizontal gusset plate 4 of the column material 1 at the joint portion between the column material 1 and the mounting steel pipe 2. It becomes a state.

  Thus, since the steel pipe side horizontal gusset plate 10 can be temporarily placed on the column side horizontal gusset plate 4 (temporary placement), the mounting steel pipe 2 in operation remains unstable while being suspended on the crane. The situation can be avoided, and the safety and simplification of work can be promoted.

  Then, as shown in FIGS. 6 and 7, the mounting steel pipe 2 is moved until the steel pipe side horizontal gusset plate 10 comes into contact with the stopper 8. The stopper 8 is formed in the bolt holes 6a, 6b, 6c, 6d formed in the columnar material vertical gusset plate 11 and the steel pipe side vertical gusset plate 11 when the steel pipe side horizontal gusset plate 10 comes into contact with the stopper 8.

  By providing the stopper 8 in this way, it is possible to prevent the steel pipe side horizontal gusset plate 10 from being inserted into the upper cut portion 7 more than necessary. Moreover, this stopper 8 can also prevent slipping down when the attachment steel pipe 2 attaches the stress material which has inclination with respect to columns, such as a diagonal material.

  The bolts 6a, 6b, 6c, 6d of the columnar vertical gusset plate 11 and the bolt holes 13a, 13b, 13c, 13d of the mounting steel pipe 2 are inserted and tightened to fix the mounting steel pipe 2 to the columnar material 1. .

  According to the joint structure of the present embodiment, the mounting steel pipe 2 can be temporarily placed, so that the bolt holes can be easily positioned and work efficiency can be improved.

Moreover, since the column material 1 and the mounting steel pipe 2 in this embodiment are gussets (column side cross gusset 3, steel pipe side cross gusset 9) joined by bolts, they are like splice plates used for conventional joining. It is no longer necessary to provide a dedicated member for joining, and it is possible to reduce the labor and cost of work.

  In addition, according to the joint structure of the present embodiment, the gussets of the column member 1 and the mounting steel pipe 2 are brought into contact with each other by one-surface shearing, so that the length of the screw portion of the bolt can be shortened.

  The column material and the stress material of this example are H steel as in Example 2, but in this example, a case where two H steels are coaxially joined will be described.

(About joining)
Next, the joining structure including the operation when joining the first H steel 20 and the second H steel 30 will be described. Also in the case of the present embodiment, the second H steel 30 is suspended with a crane or the like and moved to the joining position with the first H steel 20 to perform the joining work.

9 and 10 show a state before joining the first H steel 20 and the second H steel 30, and FIGS. 11 and 12 show a joined state between the first H steel 20 and the second H steel 30. FIG. To attach the second H steel 30 to the first H steel 20, the fourth flat plate 32 of the second H steel 30 is inserted into the lower notch 25 of the first H steel 20 and the upper notch 35 of the second H steel 30. The 2nd H steel 30 is moved so that the 1st flat plate 21 of the 1st H steel 20 may be inserted in (arrow P direction in FIG. 9, arrow Q direction in FIG. 11).

  And the 2nd H steel 30 is moved until the 4th flat plate 32 contact | abuts to the stopper 26, and the position of the bolt hole 24 provided in each of the 1st H steel 20 and the 2nd H steel 30 and the bolt hole 34 is match | combined. (See FIG. 11). The stopper 26 is preferably disposed at a position where the bolt hole 24 and the bolt hole 34 coincide with each other.

  At this time, the fourth flat plate 32 and the second flat plate 22 are brought into contact with each other, and the bolt holes 24 and the bolt holes 34 are aligned. That is, the second H steel 30 is placed on the second flat plate 22, the second H steel 30 is moved little by little, and the bolt holes 34 are aligned with the positions of the bolt holes 24.

  Further, by providing the stopper 26 on the second flat plate 22, the first flat plate 21 of the first H steel 20 excessively enters the upper cut portion 35 and the fourth flat plate 32 of the second H steel 30 is cut downward. It is possible to prevent the portion 25 from entering too much. Moreover, this stopper 26 can also prevent slipping off from the column material when the second H steel 30 having an inclination with respect to the column material (first H steel 20) such as a diagonal material is attached.

  Moreover, since the H steels (the 1st H steel 20 and the 2nd H steel 30) are directly joined by the volt | bolt, the joining structure of the pillar material of the structure in this embodiment and a stress material is like a splice plate. There is no need to provide a member dedicated to joining, and it is possible to reduce the labor and cost of the work.

  In addition, according to the joint structure of the present embodiment, the lengths of the bolts are shortened because the H steels (specifically, the first connecting plate 23 and the second connecting plate 33) are brought into contact with each other by one-surface shearing. be able to.

  The column material and the stress material in this example are H steels having a cross-sectional shape of H type, and in this example, a structure in the case where two H steels are joined so as to form a right angle will be described.

(Constitution)
Below, the structure of the column material and stress material in a present Example is demonstrated. The joint structure of the present embodiment is a structure when two H steels are joined vertically. In addition, the description which overlaps with Example 1, 2 is abbreviate | omitted.

  In FIG. 13, the joining structure of the column material 40 and the stress material 50 of a present Example is shown. The column member and the stress member of this embodiment are a pair of parallel members (first horizontal plate member, second horizontal plate member) facing each other, and a connecting member (first member) interposed between the parallel members and connecting the parallel members. It is a so-called H-steel having a H-shaped cross-section with one vertical plate and a second vertical plate. Therefore, hereinafter, the H steel as the column material will be described as the first H steel 40, and the H steel as the stress material will be described as the second H steel 50.

  The first H steel 40 includes a first flat plate 41 and a second flat plate 42 that face each other in parallel, and a first connecting plate 43 that is interposed between the first flat plate 41 and the second flat plate 42 and connects these flat plates. .

  Further, the first connecting plate 43 of the first H steel 40 of the present embodiment is provided with a gusset plate (joint plate) 44 for joining the second H steel 50. As shown in FIGS. 14 and 15, the gusset plate 44 is a rectangular plate. It is preferable that the first H steel 40 is formed of a member having the same or equivalent strength.

  The gusset plate 44 is provided with a bolt hole 45 through which a bolt for fixing the second H steel 50 to the first H steel 40 is passed.

  Further, a stopper 55 is disposed at a right angle portion formed by the first connecting plate 43 and the second flat plate 42. Moreover, the 2nd H steel 50 is interposed between the 3rd flat plate 51 and the 4th flat plate 52 which face each other, and the 3rd flat plate 51 and the 4th flat plate 52, and from the 2nd connection plate 53 which connects these flat plates.

And the 2nd H steel 50 can be fixed to the 1st H steel 40 by inserting and fixing a bolt in this hole.

  Further, the second connecting plate 53 is provided with a cut portion 56 at the ends of the third flat plate 51 and the second connecting plate 53. The cut portion 56 is cut out inward from the end portion of the second connecting plate 53.

  Furthermore, as shown in FIG. 14, the deepest part of the notch part 56 of the 2nd connection board 53 of a present Example is curving. Thereby, the concentration of stress generated when the column member 40 and the stress member 50 are joined can be relaxed. Note that the third flat plate 51 located above the notch 56 is also cut out in accordance with the size of the notch 56. That is, the cut portion 56 is formed by cutting out the third flat plate 51 and the second connecting plate 53.

  The above is the configuration of the column material (first H steel) 40 and the stress material (second H steel) 50 in the present embodiment.

(About joining)

In order to attach the second H steel 50 to the first H steel 40, the second connecting plate 53 of the second H steel 50 and the gusset plate 44 abut and the fourth flat plate 52 of the second H steel 50 is attached to the first H steel 50. The second H steel 50 is moved so as to come into contact with the upper surface of the first flat plate 41 of the steel 40 (arrow R direction in FIG. 14, arrow S direction in FIG. 15). At this time, since the first flat plate 41 of the first H steel 40 enters the cut portion 56, the movement of the second H steel 50 is not hindered.

  Further, the second H steel 50 is moved until the fourth flat plate 52 of the second H steel 50 comes into contact with a stopper 55 provided on the second flat plate 42 of the first H steel 40. After the second H steel 50 is moved to the position of the stopper 55, the second H steel 50 is temporarily placed on the second flat plate 42, and the bolt holes 45 provided in the gusset plate 44 and the second H steel are placed. Alignment with the bolt holes 54 provided in the 50 second connecting plate 53 is performed.

  Then, after aligning the positions of both bolt holes, the bolts are inserted into the holes, and the gusset plate (first H steel 40) 44 and the second H steel 50 are fixed.

  Thus, since the bolt can be inserted and fixed in the bolt hole aligned in a state in which the second H steel 50 is stabilized (that is, temporarily placed), work safety and simplification are promoted. be able to.

  Moreover, according to the joint structure of this embodiment, since the H steels (specifically, the gusset plate 44 and the second connecting plate 53) are brought into contact with each other by one-surface shearing, the bolt length is shortened. Thus, the joining work can be simplified.
