Description

TECHNICAL FIELD The present invention relates to a plumbing adjustment jig and a plumbing adjustment method, and more particularly to a plumbing adjustment jig used when rebuilding a building frame and a plumbing adjustment method using the same.

When constructing a steel-framed or steel-framed reinforced concrete building, in order to ensure the accuracy of the verticality of the steel-framed columns, so-called rebuilding is performed to correct the tilting, horizontality, and bending of beams and columns after erection. . Conventionally, as a method of rebuilding, a wire rope is wound around the column or beam, and the wire rope is tightened with a lever block (registered trademark) or the like to keep the vertical accuracy of the steel frame column within a predetermined accuracy. rice field. In addition, in order to rebuild the frame, for example, Patent Document 1 discloses a configuration in which wire ropes and chains arranged obliquely at the lower and middle portions of a column are wound up by an electric traction machine. .

Japanese Utility Model Laid-Open No. 6-78387

Conventionally, wire ropes and the like used for rebuilding have been attached by hooking hooks provided at the ends to omega-shaped or ring-shaped reinforcing bars (omega bars) embedded in the foundation or the earthen floor. The omega muscle embedded in the foundation or the soil will become unnecessary after rebuilding, but if left as it is, it will affect the fit of the interior and exterior. Therefore, it is necessary to cut the omega muscle after use, and the task of cutting the omega muscle is heavy.

In addition, when the wire rope is wound directly around the column without using such omega-strands, there is a possibility that the wire rope will break due to the load applied eccentrically from the center of the line. In addition, if the wire rope is wrapped around the beam instead of the column head and column base, there is a possibility that the end of the flange and the wire rope will rub against each other and be cut. It takes time to wind the wire rope around the pillar and to adjust the length of the wire rope.In addition, when the wire rope is wound around the pillar, the coating of the steel frame peels off, which may require additional repainting work. there were.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a jig for adjusting erection that can attach a wire rope to be reconstructed without cutting work.

The above-mentioned subject is a plumbing adjustment jig for fixing a wire rope having a hook at its end to an earthen floor, comprising a flat plate-shaped base portion and a base portion erected on the upper surface of the base portion so that the hook of the wire rope is attached to the base portion. and an anchor member embedded in the dirt floor and detachably fixing the hook member with a bolt, the anchor member connecting the opening of the bolt hole to the surface of the dirt floor . a first plate connected to one end of the plurality of high nuts in a state where the plurality of high nuts are arranged in parallel, and the other end of the plurality of high nuts and a second plate connecting with the plumbing adjustment jig.
Since the hooking member is detachably fixed to the anchor member, it is only necessary to remove the hooking member after the rebuilding work, and there is no need to cut the reinforcing bar as in the conventional art. The hooking member does not remain, and the removed hooking member can be reused when rebuilding other columns or beams. Since the wire rope is not wound around the pillars or beams, the wire rope will not contact the flange ends of the beams and be cut off, nor will the work of winding and adjusting the length be required. Since the wire rope is not wound around the pillars and beams, the coating of the steel frame does not peel off and additional work such as recoating is not required.
Since the anchor member is buried with the bolt hole exposed on the surface of the dirt floor, the hook member can be fixed with the bolt. In addition, since a plurality of high nuts are arranged in parallel and connected to the first and second plates and embedded in the earth, the anchor member is firmly fixed to the earth.

Further, the hooking member may further include a second ring portion erected on the upper surface of the base portion perpendicularly to the ring portion and on which the hook of the wire rope is hooked. By providing the second ring portion, it becomes possible to attach wire ropes extending from two directions with one jig for erection adjustment.

Further, the subject is a erection adjustment method for adjusting erection of columns and beams using the erection adjustment jig and a wire rope, wherein the anchor member of the erection adjustment jig is embedding the hooking member to be attached to the anchor member so that the planar direction of the ring portion of the hooking member faces the mounting ring provided on the beam; and fixing the hooking member to the anchor member. attaching one end of the wire rope to the ring provided on the beam; and hooking the hook of the wire rope to the ring portion of the hooking member.

An embodiment of the present invention (hereinafter referred to as the present embodiment) will be described below with reference to FIGS. 1 to 5. FIG. In the following embodiments, the same or similar constituent elements are indicated by common reference numerals, and the scales of these drawings are appropriately changed for easy understanding.

The erection adjusting jig 10 is a jig used during erection work, for example, a jig for attaching a wire rope 106 obliquely extending from the lower surface of a beam to the earth floor to the earth floor side. The wire rope 106 has a hook 107 at its end as shown in FIG. The erection adjustment jig 10 includes a hooking member 15 on which the hook is hooked, and an earth floor anchor 20 (an example of an anchor member) for fixing the hooking member 15 to the earth floor.

The hooking member 15 includes a flat base portion 11 and a ring portion 12 erected on the upper surface of the base portion 11, as shown in FIG. The wire rope is attached to the hooking member 15 by passing the hook of the wire rope through the through hole 12 a formed in the ring portion 12 . For example, four through holes 13 are formed at predetermined intervals L in order to bolt-join the earth floor anchor 20, as shown in FIG. 2(a).

The earth floor anchor 20 (anchor member) is, for example, a member that is embedded in the earth floor when the earth floor is placed. has a first plate 22 connected to one end 21a of the and a second plate 23 connected to the other end 21b. The high nut 21 is fixed to the first plate 22 with a bolt 25 with a predetermined gap L therebetween. The high nut 21 may be fixed to the first plate 22 by welding. The dirt floor anchor 20 is buried in the dirt floor up to a position where the second plate 23 is located, with the bolt hole opening of the high nut 21 exposed on the surface of the dirt floor and oriented vertically.

Since the two high nuts 21 are embedded in the soil while being fixed by the first plate 22 at one end side (lower end side), the soil anchor 20 is difficult to come off after the embedding.

Four through holes 13 are formed in the base portion 11 of the hooking member 15 as described above. The hooking member 15 is detachably fixed to the dirt floor anchor 20 by passing the mounting bolt 24 through the through hole 13 and bolting it to the high nut 21 . When the four through-holes 13 are formed with a predetermined interval L, the user selects two adjacent through-holes 13 from among the four through-holes 13 of the hooking member 15, and attaches the mounting bolt 24. is passed through the selected through hole 13 and fixed to the earth floor anchor 20. - 特許庁Thereby, the user can fix the planar direction of the ring portion 12 (direction A in FIGS. 1 and 2A, radial direction of the through hole 12a of the ring portion 12) in the direction in which the wire rope extends.

3 and 4 show a plumbing adjustment jig 30 which is another example. The hooking member 35 of the plumbing adjusting jig 30 is provided with a second ring portion 34 in addition to the ring portion 32 in a direction orthogonal to the ring portion 32 . By providing the second ring portion 34, two wire ropes extending in two directions orthogonal to each other can be attached. In addition, when supporting two wire ropes extending in two directions perpendicular to each other with only the ring portion 32, force is also applied in a direction perpendicular to the planar direction of the ring portion 32 (direction of arrow A in FIG. 3). , becomes unstable. By providing the second ring portion 34, it is possible to attach a wire rope extending in a direction perpendicular to the planar direction of the ring portion 32, that is, in the planar direction of the second ring portion 34 (direction of arrow B in FIG. 3). Therefore, for example, the ring portion 32 is prevented from being damaged with respect to the base portion 11 . Since the construction of the dirt floor anchor 20 is the same as that of the plumbing adjustment jig 10 shown in FIGS. 1 and 2, the description thereof will be omitted.

FIG. 5 shows how the plumbing adjusting jigs 10 and 30 of the present embodiment are used. The erection adjustment jigs 10 and 30 and the wire rope 106 are used to adjust the erection of the three pillars 101 to 103 and the beams 104 and 105 that support them. Mounting rings 40 are provided on the lower surfaces of the ends of the beams 104 and 105 that connect to the pillars 102 . A wire rope 106 is stretched from the attachment ring 40 to the plumbing adjustment jig 10 fixed near the base of the pillars 101 and 103 . For the pillars 101 and 103, wire ropes 106 extend from attachment rings 40 provided on the lower surfaces of the ends of the beams 104 and 105 connected to the pillars 101 and 103, and the hooks of the two wire ropes 106 are installed and adjusted. It is attached to a jig 30 for use. A lever block 108 of the wire rope 106 adjusts the inclination of the columns 101 to 103 and beams 104 and 105 . Note that the attachment rings 40 provided on the beams 104 and 105 may be the hook members 15 .

A plumbing adjusting method using the plumbing adjusting jig 10 and the wire rope 106 will be described. First, the soil anchor 20 of the erection adjusting jig 10 is embedded in the soil. The earth floor anchor 20 is embedded in the earth floor when the earth floor is placed, that is, before the concrete in the earth hardens. At this time, the earth floor anchor 20 is embedded so that the planar direction of the ring portion 12 of the hooking member 15 attached to the earth floor anchor 20 faces the attachment ring 40 provided on the beams 104 and 105 . After the concrete has hardened, the hooking member 15 is fixed to the earth floor anchor 20 by bolting for the erection adjustment. The upper ends of the wire ropes 106 are attached to attachment rings 40 provided on the beams 104,105. A hook 107 of a wire rope 106 is hooked on the ring portion 12 of the hooking member 15 . A lever block 108 of the wire rope 106 is used for erection adjustment. After the erection adjustment, the hook member 15 is removed from the earth floor anchor 20.例文帳に追加Since the earth floor anchor 20 is almost buried, it does not affect the fit of the interior and exterior, and cutting work is not required after erection adjustment.

The earth floor anchors 20 embedded in the earth floor can be used not only for erection adjustment, but also for fixing scaffolding inner braces 200 that support the scaffolding shown in FIG. 6 from the inside of the building. Conventionally, the scaffolding inner stay 200 has been joined to a frame anchor or joined by forming a hole-in anchor in the foundation 201 . However, when it is joined to the skeleton anchor, the scaffolding inner stay 200 has to be removed from the skeleton anchor at the start of erection. In addition, hole-in anchors require a lot of time and effort to manufacture, and thus impose a heavy load during construction. Therefore, by burying the earth floor anchors 20 at the time of placing the earth floor 202, the scaffolding inner stay 200 can be fixed with relatively little effort.

In the above embodiment, the plumbing adjustment jig according to the present invention has been mainly described. However, the above embodiment is merely an example for easy understanding of the present invention, and does not limit the present invention. The present invention can be modified and improved without departing from its spirit, and the present invention includes equivalents thereof.
