[Conventional technology]

For reinforcing steel work when constructing high-rise RC buildings, after the on-site installation of column bars is completed, There is a method of incorporating pre-assembled beam reinforcement into the upper end of the column reinforcement as a cage-like beam assembly reinforcement. , this is done by suspending and lowering the beam assembly reinforcing bars and inserting column reinforcements between the beam reinforcements. It is.

0003 However, in high-rise RC buildings, it is necessary to increase the number of column reinforcements and beam reinforcements for strength reasons. Therefore, when inserting the beam assembly reinforcing bars into the column reinforcements, it is necessary to insert the densely arranged column reinforcements into the column reinforcements. Similarly, it becomes extremely difficult to pass the beam between the densely arranged beam reinforcements.

0004 Therefore, as shown in Fig. 7, the column main reinforcement 1 is attached to the tip of the main column reinforcement 1. A guide member 2 that can be easily passed between beam reinforcements (not shown) is conventionally used. It is being

[Problem that the idea aims to solve]

However, such a conventional guide member 2 is simply formed as a conical rigid body. Since the guide member 2 itself cannot be bent, the column main reinforcement 1 The dimensional tolerance for the hanging position of the beam assembly reinforcing bars is small. Therefore Therefore, even if guide member 2 is used in this way, the main It is necessary to improve the accuracy of the beams, that is, the horizontal accuracy when suspending the beams. As expected, the work of incorporating beam reinforcements is difficult.

[0006] In addition, in order to eliminate the work of assembling beam reinforcements, column reinforcements and beam reinforcements are assembled at the factory. Alternatively, there is a method of pre-assembling the reinforcing bars as one piece on site and then erecting this integrated reinforcing bar on site. . However, in this case, the entire reinforcing bar structure becomes significantly large and difficult to transport. Not only will it be difficult, but the construction work will be extensive and the construction period will be extended. There was a problem.

[0007] Therefore, in view of these conventional problems, the present invention was developed by suspending beam assembly reinforcing bars. By making it extremely easy to insert into the main column reinforcement in the state, the column reinforcement and beam reinforcement can be separated. We provide guide members for beam assembly reinforcing bars that enable each assembly work to be carried out in a fixed state. The porpose is to do.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Figure 1? 6 shows a guide member for beam assembly reinforcing bars according to the present invention and its usage method, and FIG. 2 is a partially cutaway side view showing the main part of the guide member 10, and FIG. 3 to 6 are perspective views showing how the guide member 10 is attached when the guide member 14 is assembled. The following is a step-by-step process of installing beam assembly reinforcing bars 14 into column main bars 12 using guide members 10. These are process diagrams schematically showing each.

[0013] As shown in FIG. The reinforcement 16 and the space defined by the main beam reinforcement 16 are surrounded in the circumferential direction from the outside of the main beam reinforcement 16. It is constructed by combining a large number of stirrups 18 into a basket shape. In addition, the beam assembly The vertical reinforcing bars 14 have stirrups 18 removed from the portion where the column main bars 12 are inserted. The space defined by the main column reinforcements 12 can be circumferentially surrounded from the outside of the main column reinforcements 12. A hoop muscle 20 is attached.

[0014] A plurality of pillar main reinforcements 12 are arranged vertically from the upper end of the pillar 22 in which concrete is poured. It is installed protrudingly. Then, when incorporating the beam assembly reinforcing bars 14 into the column main reinforcements 12, This column main reinforcement 12 is inserted into the hoop reinforcement 20 of the beam assembly reinforcement 14. Ru.

[0015] The guide member 10 is used when assembling the beam assembly reinforcement 14 into the column main reinforcement 12. and is attached to the tip (upper end) of each column main reinforcement 12. guide member 10, as shown in FIG. It is composed of a long guide rod 26 that protrudes from the outside. As a guide rod 26 For this purpose, steel rods or round steel rods used for regular reinforcing bars may be used.

[0016] The cap 24 has a recess at the center of its lower end to be fitted to the column main reinforcement 12. It has a fitting part 28 formed therein, and a direction from the fitting part 28 side to the guide rod 26 side. Once, a tapered portion 30 was formed whose outer diameter gradually decreased, and its overall shape It is constructed in the shape of a bell. The inner diameter of the fitting portion 28 is the same as that of the column main reinforcement 12. As shown in FIG. 2, this fitting portion 28 is formed to have a larger diameter than the outer diameter of It is removably fitted to the tip (upper end) of 2.

[0017] Next, the assembly of the beam assembly reinforcing bars 14 and the column main reinforcements 12 is performed using the guide member 10. The loading work is shown in sequence in FIGS. 3 to 6. First, as shown in Figure 3, The beam assembly reinforcing bars 14 assembled at the factory or on site are suspended by a crane, etc., and the columns 22 are position it above. At this time, the tip of the column main reinforcement 12 protruding from the upper end of the column 22 The guide member 10 is attached. In addition, the installation work of the guide member 10 is , can be done on top of the column 22 without having to go up on the beam assembly reinforcing bar 14, making it easy to work at high places. No work is necessary.

[0018] Subsequently, the beam assembly reinforcing bars 14 are gradually lowered, and the beam assembly reinforcing bars 14 are attached to the guide. When approaching the guide rod 26 of the guide member 10, bend the tip of the guide rod 26 appropriately. The beam is deformed to match the predetermined position of the beam assembly reinforcing bar 14. In this way, the guide rod 26 After aligning the tips of the beam assembly reinforcing bars 14, as shown in Figure 4, lower the beam assembly reinforcing bars 14 further. . At this time, the hoop reinforcements 20 of the beam assembly reinforcing bars 14 come into contact with the column main reinforcements 12, that is, , when the hoop reinforcement 20 hits the column main reinforcement 12, it can be removed by hitting the guide member 10. The hoop reinforcement 20 is deformed to eliminate the collision with the column main reinforcement 12, and it can be incorporated more easily. It can make your work easier.

[0019] Then, as described above, when the beam assembly reinforcing bars 14 are further lowered, the column main reinforcing bars 1 2, as shown in FIG. After that, as shown in FIG. 6, the guide member 10 is removed from the column main reinforcement 12. By removing it, the assembly of the beam assembly reinforcing bars 14 and the column main reinforcing bars 12 is completed. stop After the assembly is completed in this way, the outside of the beam assembly reinforcing bars 14 is covered with a formwork (not shown). By covering it and pouring concrete inside it, this concrete hardens. , a beam integrated with the column 22 can be constructed.

[0020] As described above, in the guide member 10 of this embodiment, the tip of the column main reinforcement 12 is A long guide rod 26 is integrally protruded from the upper end of the cap 24 attached detachably. The guide rod 26 is installed before the beam assembly reinforcement 14 and the column main reinforcement 12 are assembled. Since it has been inserted into the predetermined position of the beam assembly reinforcing bar 14, as the beam assembly reinforcing bar 14 descends, The guide rod 26 guides the beam reinforcement of the beam assembly reinforcing bars 14, and guides the beam assembly reinforcement 14 as a whole. The position can be adjusted with respect to the column main reinforcement 12.

[0021] Further, since the guide rod 26 is long, the amount of bending deformation thereof can be increased. This allows the tolerance of the hanging position of the beam reinforcement to be significantly increased, and the guide part Inserting the material 10 into the beam assembly reinforcing bars 14 is made much easier. And said guy After inserting the dowel rod 26 into the beam assembly reinforcing bar 14, the beam assembly reinforcing bar 14 is simply lowered. By doing so, the incorporation with the column main reinforcement 12 can be completed.

[0022] Furthermore, the cap 24 of the guide member 10 is fitted into the column main reinforcement 12 at the center of the lower end. It has a fitting part 28 in which a recess is formed for fitting, and the fitting part 28 side is A tapered portion 30 is formed whose outer diameter gradually decreases toward the guide rod 26 side. Since the entire structure is approximately bell-shaped, the beam assembly reinforcing bars 14 are connected to the guide rods 26. When passing through the cap 24 while being guided by the outer surface of the cap 24, The beam can be smoothly guided downward along the . In addition, the guide member 10 When attaching to the column main reinforcement 12, a recess with a larger diameter than the outer diameter of the column main reinforcement 12 is bored. It is only necessary to fit the fitted fitting part 28 into the tip of the column main reinforcement 12, and the fitting part 28 can be easily attached and detached. It's extremely easy. In addition, in this way, the fitting part 28 of the cap 24 is formed. Since the inner diameter of the recess is larger than the outer diameter of the column main reinforcement 12, the tip of the guide rod 26 can be rotated around the fitting part 28 with respect to the column main reinforcement 12, and the above-mentioned guide Coupled with the bending deformation of the guide rod 26 itself, the guide rod 2 It is easy to align the tips of 6.

[0023] Furthermore, the guide member 10 is used to assemble the column main reinforcement 12 and the beam assembly reinforcement 14. By making it easier to insert, the blocks of column assembly reinforcing bars 14 can be made larger and made all at once. It becomes possible to assemble to a plurality of columns 22. In this embodiment, the length of the beam assembly reinforcing bars 14 is The width is formed at three locations of the pillar 22.

[0024] In this way, by using the guide member 10 of this embodiment, the beam assembly reinforcing bars 14 After manufacturing the main column reinforcement 12 (column reinforcement 12) separately, they are assembled on site. This makes it possible to save labor when constructing high-rise RC buildings.

[0025] In addition, in this example, prior to incorporating the beam assembly reinforcing bars 14 into the column main reinforcements 12, Therefore, the guide member 10 should be attached to the upper end of each column main reinforcement 12. However, the guide member 10 is vertically movable relative to the hoop reinforcement 20 of the beam assembly reinforcement 14. The beam assembly reinforcing bars 14 are lowered from above the column main reinforcing bars 12 and each Fit the cap 24 of the guide member 10 onto the upper end of the pillar main reinforcement 12, and then If the beam assembly reinforcing bars 14 are further lowered, the beam assembly reinforcing bars 14 will be As in the embodiment, the column main reinforcement 12 is easily guided by the guide rod 26 of the guide member 10. can be incorporated into.
