Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower member, such as a steel member or other long member, which is first installed on a foundation such as the ground, or a vertical member in a construction site of a structure. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long member joining refitting device that rebuilds a long member that has been built in when performing a building work that vertically builds a lower pillar member that has been built in a vertical direction.

[0002]

2. Description of the Related Art In a construction site of a structure, for example, a case where a column member such as a steel frame column or another long member is vertically built on a lower column member is performed. Will be installed on the lower pillar member into which it will be installed so as to take a substantially vertical posture. Then, the lower pillar member and the upper long member are temporarily fixed, and then the work is rebuilt. This re-building work is conventionally performed by pulling wires in four directions toward the lower part near the upper end of the upper elongated member,
A method is used in which the wires are rebuilt by pulling each wire using a tensioner and kept vertical until the long member is permanently joined to the lower pillar member.

[0003]

However, in the method of rebuilding using this wire, it takes a lot of time to attach and detach the wire and attach and detach the tensioner, and many temporary installations such as the wire and the tensioner are required. Materials are needed. Further, by stretching the wire in four directions, the wire often intersects with another wire for re-building work that is proceeding at the same time, which often becomes an obstacle to the entire construction site, which causes a decrease in work efficiency. Further, since it takes time to perform the main joining of the long members, the wires may be stretched and the tensioner may be loosened, and the long members may not be kept vertical and may need to be rebuilt again. Furthermore, it takes a lot of time and labor to remove the reassembly device after the long members are permanently joined.

Therefore, according to the present invention, the long member provided in the building operation for vertically building the upper long member on the upper end portion of the lower member is used for rebuilding the long member and joining it to the lower member. Rebuilding device for joining members that can be easily rebuilt in a short time without hindering other construction work An object is to provide a repair device.

Further, according to the present invention, a long member is provided for re-installing and joining the long member that has been installed in a building operation in which the upper long member is vertically built on the upper end portion of the lower member and joined to the lower member. It is a rebuilding device for joining members, and it is possible to provide a rebuilding device for joining long members that can be easily and quickly removed after the main joining of the lower member and the upper member is completed. It is an issue.

[0006]

In order to solve the above-mentioned problems, the present invention provides the following three types of erecting devices for joining long members.

1. Rebuilding device for the first type of long member joining Rebuilding the long member built in the building work to build the upper long member in the vertical direction on the upper end of the lower member, and rebuilding and joining it to the lower member An erecting device for joining long members, which is provided for the first erection piece provided in advance on the side surface of the upper end portion of the lower member, and the first erection piece corresponding to the side surface of the lower end portion of the upper member. The first and second erection pieces in a state where a pair of splice plates are applied from both sides of the first and second erection pieces and temporarily fixed to both of the second erection pieces provided in advance in the position. A re-equipment device for joining long members, which is mounted between the first and second members, the first member including a bifurcated portion and a screw rod protruding from a back surface of the bifurcated portion in a direction opposite to the bifurcated portion, and a bifurcated portion. Department and A second member protruding from the back surface of the bifurcated portion in a direction opposite to the bifurcated portion and including a threaded rod having a thread opposite to that of the threaded rod of the first member; and a threaded portion screwed into the threaded rod of the first member. And an intermediate drive member having back-to-back screw portions to be screwed into the screw rods of the second member, and the forked portion of the first member is fitted and engaged with the upper end portion of the first erection piece. And the forked part of the second member is fitted and engaged with the lower end of the second erection piece, or the forked part of the first member is fitted and engaged with the lower end of the second erection piece. The bifurcated portion of the second member is fitted and engaged with the upper end portion of the first erection piece, and the intermediate drive member is rotated so that the entire length between the first and second erection pieces can be adjusted for expansion and contraction. For joining long members Chi go back apparatus. The screw rod of the first member and the screw rod of the second member are
Each may be a male screw rod or a screw rod having a female screw drilled therein, and the screw portion of the intermediate drive member may be a female screw portion or a male screw portion depending on the screw of the screw rod.

When the erecting device for joining long members is used, both threaded portions of the intermediate drive member are screwed into the threaded rod of the first member and the threaded rod of the second member, respectively, to be assembled. . Both the first erection piece preliminarily provided on the upper end side surface of the lower member and the second erection piece preliminarily provided on the lower end side surface of the upper elongated member at a position corresponding to the first erection piece. In the state where the pair of splice plates are applied from both sides of the first and second erection pieces and temporarily fixed,
It is inserted between the first and second erection pieces.
This insertion is not disturbed by a pair of splice plates,
For example, this can be done on the front side of the splice plate.

Although not limited thereto, the first and second erection pieces are usually provided in four sets on the peripheral surfaces of the upper and lower members to be joined at approximately 90 ° center angle intervals. Therefore, the erecting device for joining long members is inserted into each of the first and second erection pieces of each set. At this time, the forked part of the first member in each erecting device for joining long members is fitted and engaged with the upper end of the first erection piece, and the forked part of the second member is moved to the second part.

Can be fitted into and engaged with the erection piece, thus making it difficult for the erection piece to come off.

Then, the inclination of the upper elongated member from the vertical direction is measured by a vertical measuring device such as plumb bob. When the inclination is known, in one or more of the rebuilding devices arranged around the upper and lower members to be joined, the intermediate driving member is pivotally operated in an appropriate order to move the intermediate driving member to both sides. 1. The bifurcated portions of the first and second members are driven to project in opposite directions to extend the entire device, thereby widening the gap between the first and second erection pieces against the resistance of the temporarily fixed splice plate, As a result, the periphery of the upper long member is partially lifted to control the posture of the member, and the member is rebuilt. In this way, the upper elongated member is adjusted to the vertical posture by rotating the one or more intermediate driving members in an appropriate order. Thus, the upper long member is finally placed in the vertical posture.

After that, for example, the splice plate is firmly fixed to the first and second erection pieces to which it is applied, and the lower member and the upper elongated member are firmly and temporarily joined. Then, after the upper and lower members are main-joined by welding or the like, or prior to the main-joining by welding or the like, the intermediate drive member in each of the long member joining repositioning devices is rotated in the opposite direction to shorten the device, Thus, the erecting device for joining each long member is removed from the first and second erection pieces, and after the main joining of the upper and lower members is finally completed, the splice plate is removed from the first and second erection pieces. Thus, the upper elongated member is vertically joined to the lower member.

As described above, the reassembling device for joining long members described above can perform the reassembling work easily, in a short period of time, and without hindering other construction work. It can be provided easily and inexpensively. Further, after the main joining of the lower member and the upper elongated member is completed, it can be easily removed in a short period of time, which is easy to handle. In the erecting device for joining long members described above, the forked portion of the first member and the forked portion of the second member are formed to be the same or substantially the same, and each of the forked portions is the first. The upper end of the erection piece and the lower end of the second erection piece may be fitted and engaged with each other. This makes the device easier to use, depending on the shape and thickness of the erection piece. Also, the manufacture of the device is simplified.

In order to make it easier to rotate the intermediate drive member by using a wrench or the like, it is preferable that the portion to be rotated is formed in a polygonal cross section, for example, a hexagonal cross section. Further, the bifurcated portions of the first member and / or the second member can be formed, for example, in a U-shaped cross section, and the bifurcated portions of this form are stably fitted to the ends of the erection piece. Easy to match. Further, it is easy to fit the end portion of the erection piece while sliding it from the side (in other words, from the free space side (or from the front side)).

By fitting and engaging, the end surface of the second member opposite to the bifurcated portion is made to face the upper end surface of the first erection piece, and the second member is further rotated to extend the entire apparatus to thereby extend the device. The end face can be brought into contact with the first erection pieces, and thus, the state in which they are unlikely to fall off from these erection pieces can be made. The former device, in which the bifurcated portion of the first member is fitted and engaged with the upper end portion of the first erection piece, is easier to install the device, and the former can be recommended.

In any case, the inclination of the upper elongated member from the vertical direction is then measured by a vertical measuring device such as plumb bob. When the inclination is known, one or two of the rebuilding devices arranged around the upper and lower members to be joined
In the above, by rotating the second member in an appropriate order to drive the first and second members in the opposite directions relatively, the entire device is extended, and thereby the resistance of the temporarily fixed splice plate is increased. Against this, the gap between the first and second erection pieces is widened, and by extension, the periphery of the upper elongated member is partially lifted to control the posture of the member and reassemble.

In this way, by rotating one or more second members in an appropriate order, the upper elongated member is adjusted to the vertical posture. Thus, the upper long member is finally placed in the vertical posture. After that, for example, the splice plate is firmly fixed to the first and second erection pieces to which the splice plate is applied, and the lower member and the upper elongated member are firmly and temporarily joined. Then, after the upper and lower members are permanently joined by welding or the like,
Alternatively, prior to the main joining by welding or the like, the second member in each long member joining repositioning device is rotated in the opposite direction to shorten the device, whereby each long member joining refitting device is installed. The splice plate is detached from the first and second erection pieces, and finally after the main joining of the upper and lower members is completed, the splice plate is detached from the first and second erection pieces. Thus, the upper elongated member is vertically joined to the lower member.

As described above, the second type of elongate member joining / reassembling device can also perform the reassembling work easily, in a short period of time, and without hindering other construction work. The structure is simple and can be provided at low cost. Further, after the main joining of the lower member and the upper elongated member is completed, it can be easily removed in a short period of time, which is easy to handle. In the above-described second type elongate member joining repositioning device, as with the first type long member joining repositioning device, a wrench or the like is used for the second member that is rotationally driven. In order to make it easier to rotate, it is preferable that the portion to be rotated is formed in a polygonal cross section, for example, a hexagonal cross section.

Further, the bifurcated portion of the first member can be formed, for example, in a U shape in cross section, and the bifurcated portion of this form is easily and stably fitted and engaged with the end portion of the erection piece. Further, it is easy to fit the end portion of the erection piece while sliding it from the side (in other words, from the free space side (or from the front side)).
