Description

  The present invention relates to a joint assembling apparatus for temporarily attaching an arm (joint) for forming a floor surface of each floor to a steel pillar that is a pillar of a steel structure building at a regular position of the pillar. is there.

  Pipes and H-shaped steel are used for the struts that make up the steel-frame building, but on the way, arms such as H-shaped steel that form the floor of each floor (this is called the joint) are attached. In order to build a steel-framed building accurately, the joint must be assembled to the support as designed. Conventionally, fittings are mounted on a pillar and fittings on an H-shaped steel with unstable accuracy, positioned with a swirling member, right angle and parallel ruler, etc., then temporarily fixed by welding. Was transferred to the full-scale welding. For this reason, it cannot be assembled with sufficient accuracy, and further, the efficiency is poor and the number of people is large.

For this reason, this inventor has proposed the joint assembling apparatus of the following patent document 1, and had a certain effect. However, in the case of this previous example, since the support posts and joints are placed directly on the surface plate, the sparks of welding may fly when scratching, and the surface plate will be damaged. In many cases, there are many types of instruments to be operated and the operation is complicated. Furthermore, in this prior example, there is a case where the joint is attached obliquely with respect to the support column, that is, the so-called inclined joint cannot be attached.

  The present invention solves such a problem. In short, it is possible to reduce the cost of a joint assembly apparatus by reducing the types of instruments necessary for setting up the support posts and joints and simplifying the operation thereof. In addition to the implementation, it is also possible to attach an inclined joint.

  Under the above-mentioned problems, the present invention is the joint assembly device according to claim 1, wherein the joint is temporarily attached at a predetermined angle to the support lying on the surface plate. , The first unit used when the column is supported parallel to the surface plate and set at a certain height, and the protruding arm of the right angle joint having the arm protruding at right angles from the column to the column The second ruler unit used when setting and supporting in a regular position and the third ruler used when setting and supporting the base of a right angle joint that does not have an overhanging arm in a regular position with respect to the column A ruler unit, a fourth ruler unit that is used to support an inclined protruding arm of an inclined joint having an arm that tilts and protrudes from the support column at a normal position with respect to the support column, and an inclined protrusion Set the base of the inclined joint without arms in a normal position with respect to the column. Is obtained by providing a Joint assembling apparatus, characterized in that those combining the fifth and ruler unit suitably used when.

  According to the above means, since the five types of the first to fifth ruler units are sufficient for setting the support and the right angle and inclined joints, the types can be reduced, the cost is reduced, and the operation is simplified. Is done. In addition, both right-angle and inclined joints can be installed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of each element of a column. A steel column is composed of a flat base 1, a column 2 made up of a square pipe or H-shaped steel standing on the base 1, a column 2 and a column 2. And a joint 5 in which an arm 4 such as an H-shaped steel is taken out from a base (diaphragm) 3 in order to form a floor of each floor in the horizontal direction. In this case, the vertical and horizontal dimensions of the arm 4 may be the same as the vertical and horizontal dimensions of the support column 2 or may be small. Here, the opening 5 is a right angle opening 5 that protrudes the overhanging arm 4 at a right angle with respect to the column 2 and the overhanging arm 4 is extended in all directions. As for the extending direction of the arm 4, there are only one to three directions depending on the position where the column 2 is raised.

  In addition, there is an inclined joint 7 having an inclined extending arm 6 that protrudes while tilting the arm with respect to the support column 2 as a joint used for an inclined floor or roof construction. The tilted arm 6 in the tilted joint 7 is also projected in one to four directions, but many roof construction projects are projected only on one side. Also, the vertical and horizontal dimensions may be the same as those of the support 2 or may be smaller.

  FIG. 2 is a cross-sectional view of the surface plate 8 constituting the joint assembling apparatus. The surface plate 8 is parallel to the bases 10a and 10b with a space 9 between the two surface plates 8a and 8b. It was installed in. The bases 10a and 10b can be leveled by jack bolts. The column 2 is laid in parallel on the space 9 of the above-described surface plates 8a and 8b so that the centers thereof coincide with each other. At this time, the width of the space 9 is larger than the width of the column 2 that is generally used. Widely set. In addition, although the support | pillar 2 of this example is a square pipe, there exist a thing of a round pipe and H-shaped steel besides this.

  In this case, to give an example of dimensions, the length of the surface plate 8 is set to about 3 mm, the total width is about 2.1 to 2.5 m, and the width of the space 9 is set to about 600 to 1000 mm. Furthermore, the surface plate 8 is set to about 15 mm by connecting several things corresponding to the length of the support column 2 that is normally used. The surface of the surface plate 8 has numerous tap holes 11 at a constant (for example, 50 mm) pitch along the longitudinal direction (hereinafter referred to as the Z-axis direction) and the short direction (hereinafter referred to as the X-axis direction). In addition, a scale (not shown) is appropriately attached in the Z-axis direction. Furthermore, a scale (not shown) is appropriately attached in the X-axis direction at an appropriate interval.

  FIG. 3 is a plan view showing a state in which the support 2 is laid on the surface plate 8, and the right angle joint 5 and the inclined joint 7 are set at the normal positions with respect to the support 2 using the units according to the present invention. However, each of these units supports the first ruler unit 12 that supports the column 2 in parallel with the center of the surface plate 8 and supports the protruding arm 4 of the right-angled joint 5 at a normal position with respect to the column 2. The second ruler unit 13 and the third ruler unit 14 that supports the base 3 of the right angle fitting 5 having no overhanging arm in a normal position with respect to the column 2, and the inclined overhanging arm 6 of the inclined port 7 are connected to the column 2 The fourth ruler unit 15 is supported in a normal position with respect to the base, and the fifth ruler unit 16 holds the base portion 3 of the inclined joint 7 having no inclined protruding arm 6 in the normal position with respect to the column 2. The

  4 is a plan view when the support 2 is supported on the surface plate 8 by the first ruler unit 12, and FIG. 5 is a partially sectional side view. The first ruler unit 12 is between the surface plates 8a and 8b. The base member 17 is passed in the X-axis direction, and the positioning member 18 is movably fixed on the base member 17. The positioning member 18 includes a column part 19a and a tail part 19b. A hollow groove 20 having a square cross section is formed in the column part 19a, and a piece member 21 can slide up and down in the groove 20. It is mated. The piece member 21 is formed with a screw hole in the horizontal direction, and a push bolt 22 having a spherical tip is screwed into the screw hole. Further, a protrusion 23 having a square cross section is formed on the back surface of the positioning member 18.

  The base member 17 is provided with mounting portions 24 having screw holes 24a formed at both ends thereof, and bolts 25 are inserted into the screw holes 24a and screwed into the tap holes 11 of the surface plate 8 to be fixed (screw holes). The pitch of 24a is an integral multiple of the pitch of the tap holes 11). At this time, it is standard that the base member 17 is placed on the left and right surface plates 8a and 8b. In addition, tap holes 11 are provided on the upper surface of the base member 17 at the same pitch as the tap holes 11 of the surface plate 8, and grooves 26 into which the protrusions 23 of the positioning member 18 are inserted are also formed. Yes. In addition, the scale is affixed suitably also to the base member 17 in the longitudinal direction.

  The case where the support | pillar 2 is set on the surface plate 8 using the above 1st ruler unit 12 is demonstrated. In this case, the tip of the push bolt 22 of the positioning member 18 is set in accordance with the width dimension of the column 2, and the column 2 is suspended in the set push bolt 22 by a crane or the like. If the positioning members 18 are arranged on both sides of the column 2 and the distance between the tips of the push bolts 22 is set to the width of the column 2, it is difficult to lower (insert) the column 2; Set. Therefore, the other positioning member 18 is not placed on the base member 17 or is sufficiently retracted even if it is placed.

  For this purpose, first, a number of first ruler units 12 are adopted according to the length of the support column 2, and the respective base members 17 are arranged at appropriate intervals in the Z-axis direction, and the X between the surface plates 8a and 8b. It passes in the axial direction and is fixed to the mounting portion 24 (screw hole 24a) with a bolt 25. In this case, since the tap holes 11 are regularly arranged on the surface plate 8, the base member 17 is accurately oriented in the X-axis direction. Next, the front surface of the column portion 19a of the positioning member 18 is set to a position more than half the thickness of the column 2 grasped from the drawing, and is fixed to the tail portion 19b with bolts 25. The movement of the positioning member 18 at this time is always moved along the X-axis direction by the protrusion 23 and the groove 26.

  Moreover, the position of the column part 19a is measured with a scale as appropriate, or is performed with an X-axis scale attached on the surface plate 8. Further, the piece member 21 is moved up and down to be positioned at the center of the column 2 and the push bolt 22 is pushed out so that the tip thereof is positioned at half the thickness of the column 2. Therefore, it is necessary to secure at least the pitch of the tap holes 11 as the adjustment allowance of the push bolt 22. The push bolt 22 is provided with a nut 22a. When the nut 22a is tightened, the piece member 21 is fastened and fixed to the hollow groove 20 of the column portion 19a. The amount of protrusion of the push bolt 22 is measured while measuring with a scale from the front surface of the column portion 19a. However, if the push bolt 22 is directly scaled, it can be read.

  When the above operation is performed on all the first ruler units 12, the support column 2 is lowered with a crane or the like so that the side surface of the support column 2 contacts the tip of the push bolt 22. At this time, the support column 2 may be placed directly on the foundation member 17, but generally it is suitable to interpose a floor plate 27.

  As described above, since the support column 2 is set at a predetermined position on the surface plate 8, after that, if it is applied to the side surface of the support column 2 with the push bolt 22 of the positioning member 18 on the other surface side of the support column 2, Both side surfaces of the column 2 are clamped by the push bolts 22 and are stably fixed. In order to simplify the operation, setting of the other side of the column 2 by the positioning member 18 may be omitted (as long as one surface of the column 2 is in contact with the push bolt 22, the column 2 is fixed to the surface plate 8. Is set to the normal position).

  Next, the case where the right angle joint 5 is attached to the support | pillar 2 is demonstrated. In this example, the right-angled joint 5 has an H-shaped steel overhanging arm 4 having a smaller dimension than a base (diaphragm) 3 having the same shape as the cross section of the column 2 in two or three sides of the column 2 (in the column 2). Is a surface that is extended at a right angle, and the base 3 and the extended arm 4 are accurately finished in advance by welding or the like. Therefore, the column 2 constituting the lower floor of the right angle joint 5 is set by the above method, and the right angle mouth 5 is set at a predetermined dimensional position and at a right angle at the upper end thereof, This is fixed by welding. A set of right angle fittings 5 for performing tacking before welding is performed using the following second ruler unit 13 and third ruler unit 14.

  6 is a plan view of the second ruler unit 13 and FIG. 7 is a partially sectional side view, but the second ruler unit 13 is not changed in that it has a base member 17 and a positioning member 19, but the base member 17 is The difference is that the mounting plate 28 fixed on the surface plate 8 with bolts 25 is supported so that the height can be adjusted. That is, the support bolt 29 is erected on the mounting plate 28, the insertion hole 30 formed in the base member 17 is passed through the support bolt 29, and the upper and lower sides thereof are tightened with the tightening nuts 31 to set a predetermined height. This height is set so that the upper surface of the base member 17 becomes the height of the lower surface of the overhanging arm 4 and is measured while measuring with a scale or the like. In this respect, the support bolt 29 is made sufficiently high, but it is preferable from the viewpoint of safety that the collar 29a is fitted to the exposed portion on the base member 17.

  Next, the positioning member 18 is operated as described above, and the push bolt 22 is extended to a predetermined position. At this time, the reference for the position (height) for attaching the right angle fitting 5 to the support column 2 is the floor surface of each floor, that is, the upper surface side of the overhanging arm 4 from the reference point of the support column 2 (the support column 2 is set up). And so on). Therefore, the positioning member 18 is first set on this side. After lowering the right angle joint 5, the lower surface side is set as necessary. The condition required for the support 2 and the right-angled joint 5 at this time is that the overhanging arm 4 is at a specified height with respect to the support 2 and is protruding at a right angle. This is done by the unit 13. In addition, the dimension from the reference point of the support 2 to the upper surface of the right angle joint 5 is performed using a Z-axis scale or the like.

  In this case, when the overhanging arms 4 of the right angle fitting 5 are horizontally extended in two directions, the respective overhanging arms 4 are set to the normal positions using the second ruler unit 13. In addition, when taking out at a right angle in at least two directions, it is suitable to set one side horizontally and the other side upward or downward. Therefore, as in this example, the overhanging arm 4 does not exist on the other side in the horizontal direction. However, at this time, it is necessary to support the base portion 3 for stability, and the third ruler. Unit 14 is used.

  FIG. 8 is a partial sectional side view of the third ruler unit 14, but the third ruler unit 14 also has a base member 17 and a positioning member 18, but the base member 17 has two surface plates. 8a and 8 are different from each other in that they are overhanging from one side. And the supporting bolt 32 which supports the lower surface near the center of the base 3 is provided, and the base 3 is supported by this supporting bolt 32 (because the above-mentioned tap hole 11 is provided on the upper surface of the base member 17. Use the appropriate one).

  As described above, when the second ruler unit 13 and the third ruler unit 14 are set in the normal positions, the upper surface side of the overhanging arm 4 of the right angle fitting 5 hits the push bolt 22 of the second ruler unit 13 and the surface of the base 3 Lower the right-angled joint 5 so that it hits the push bolt 22 of the third ruler unit 14. Next, when the positioning member 18 is set on the lower surface side of the overhanging arm 4, the upper arm and the lower surface of the overhanging arm 4 are held by the second ruler unit 13 with the push bolts 22, and the base 3 is connected to the third ruler. It is supported and stabilized by the push bolt 22 and the support bolt 32 of the unit 14. If it will be in this state, since the right-angled joint 5 will be fixed with respect to the support | pillar 2 at right angles with the height position which is calculated | required, the contact surface 33 is welded and temporary attachment is performed. At this time, since the welding surface (contact surface) 33 is floated on the surface plate 8 at a predetermined height, there is an advantage that even if a welding spark flies, it is not damaged. In many cases, the book attachment is performed at a different location.

  When the above operation is completed, the support column 2 constituting the upper floor of the right angle joint 5 is set on the upper surface side of the base portion 3 using the first ruler unit 12, and the upper surface side of the base portion 3 and the support column 2 are temporarily attached. . This operation is repeated to temporarily attach the struts 2 having a predetermined number of floors and the right angle joint 5, but the joint for attaching the roof, etc. on the top floor is projected obliquely with respect to the strut 2. The inclined joint 7 is also as described above. In this case, the fourth ruler unit 15 sets the inclined extending arm 6 and the like at the normal position, and the fifth ruler unit 16 supports the base 3 on the side not having the inclined extending arm 6.

  9 is a plan view of the fourth ruler unit 15, FIG. 10 is a partially sectional side view, and FIG. 11 is a sectional view taken along the line AA of FIG. 9. The fourth ruler unit 15 includes a base member 17 and a positioning member 18. However, since the base member 17 needs to be passed at right angles to the inclined extending arm 6, the two attachment plates 34 and 35 at both ends thereof are different. One end of the base member 17 can be rotated with respect to the support bolt 29 of the mounting plate 34. In order to read the rotation angle at this time, an angle scale 36 is provided on the mounting plate 34, and a marker 37 is provided on the base member 17. Is provided.

  The other end of the base member 17 can also rotate with respect to the support bolt 29 of the mounting plate 35. At this time, the insertion hole 30 is a long hole in the longitudinal direction, and the support bolt 29 itself is attached to the mounting plate 35. It can be moved in the longitudinal direction. That is, a groove 38 is formed on the back surface of the mounting plate 35, and a piece 39 is slidably inserted into the groove 38, and a support bolt 29 is implanted in the piece 39, and the support bolt 29 is inserted. The insertion hole 38a of the attachment plate 35 is also a long hole.

  In the usage method of the fourth ruler unit 15 described above, first, the mounting plate 34 is fixed in the screw hole 34a through the bolt 25 at an appropriate position in the X-axis direction (or the Z-axis direction). Then, the base member 17 is rotated with respect to the mounting plate 34 by the angle scale 36 and the marker 37 in accordance with the angle of the inclined extending arm 6 so as to be perpendicular to the inclined extending arm 6, and the tightening nut 31. To fix the base member 17 to the mounting plate 34.

  Next, the base member 17 is fixed to the other mounting plate 35 oriented in the Z-axis direction (or in the X-axis direction). Normally, the tap hole 11 and the mounting plate 35 of the surface plate 8 are maintained as they are. The screw hole 35a does not fit. Therefore, the piece 39 of the support bolt 29 is moved in the groove 28 and the support bolt 29 is moved by the insertion hole (long hole) 30 to adjust the screw hole 35a in the X-axis direction and the Z-axis direction so as to match the tap hole 11. Then, the bolt 25 is screwed to fix the mounting plate 35 to the surface plate 8, and the fastening nut 31 is tightened to fix the foundation member 17 to the mounting plate 35.

  When the above operation is completed, the height of the base member 17 is adjusted so that the upper surface thereof becomes the lower surface of the inclined overhanging arm 6, and the tightening nut 31 is tightened to fix the base member 17 at that position. Then, one of the positioning members 18 (which also selects the reference surface side) is adjusted and extended until the end of the push bolt 22 comes to the surface of the inclined extending arm 6. Then, when the inclined joint 7 is lowered, the other positioning member 18 is adjusted, and the tip of the push bolt 22 is brought into contact with the surface of the inclined overhanging arm 6, both surfaces of the inclined overhanging arm 6 are held between the push bolts 22. And the posture is stabilized. Accordingly, the inclined joint 7 is set at a predetermined position (height) and angle with respect to the support column 2, and therefore, the contact surface 33 with the support column 2 may be temporarily attached. At this time, if the inclined overhanging arm 6 is overhanging both of the columns 2, the respective inclined overhanging arms 6 are set using the fourth ruler unit 15. When not overhanging, the following fifth ruler unit 16 is used on the non-overhanging side.

  FIG. 12 is a partial cross-sectional side view of the fifth ruler unit 16. The fifth ruler unit 16 is the same in that it has a base member 17, a positioning member 18, a support bolt 32, etc. As with the unit 14, the base member 17 is placed only on one surface plate 8a and cannot be passed over the other surface plate 8b. Further, the base member 17 is fixed to the mounting plate 40. However, since the base member 17 and the mounting plate 40 installed in the X-axis or Z-axis direction are set obliquely, the two are pinned. 41 is pivotably connected (the base member 17 and the back surface of the mounting plate 40 are both placed on the surface plate 8 to maintain stability), and the screw hole 40a of the mounting plate 40 is made a long hole. Thus, it can be adjusted to the tap hole 11.

  Therefore, when the inclined protruding arm 6 of the inclined joint 7 does not exist, the fifth ruler unit 16 is used for the base portion 3 and the push bolt 22 of the positioning member 18 is extended to a predetermined position. When the above operation is completed, the inclined protruding arm 6 of the inclined joint 7 is applied to the push bolt 22 of the fourth ruler unit 15, and the surface of the base portion 3 is applied to the push bolt 22 of the fifth ruler unit 16. Take down 7. Next, when the positioning member 18 is set on the other surface side of the inclined extending arm 6 and the push bolt 22 is applied to the other surface of the inclined extending arm 6, the inclined extending arm 6 has both sides of the dimensional position and angle required. Since the surface is fixed, the contact surface 33 with the support column 2 may be temporarily attached by welding.
