Abstract

PROBLEM TO BE SOLVED: To execute a joint bar for a nonbearing wall as post-execution in a ground form construction method accurately at low cost. SOLUTION: Flat bars 5, 6 are positioned and fixed onto leveling concrete 3 placed prior to bar-arrangement works at the time of the execution of a building frame 10, to which the nonbearing wall must be installed, and anchor bars 8 for fixing in the building frame are welded beforehand onto the flat bars 5, 6. The joint bars 11 are fastened onto the flat bars 5, 6 exposed to the bottom section of the building frame 10 after the placing of concrete onto the building frame by welding.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for installing a reinforcing bar for a non-bearing wall in a ground foam method.

[0002]

2. Description of the Related Art In the case of providing a reinforcing bar for a non-bearing wall to be later-constructed in a ground form method in a frame, conventionally, a fixing length for the non-bearing wall is inserted so as to protrude downward from the frame. A method has been widely adopted in which a reinforcing anchor is set and then discarded concrete is poured in, thereby fixing the inserting anchor.

[0003]

However, according to the above-mentioned conventional method, it is necessary to set a reinforcing bar anchor in advance during the formation of a ground form form and then to cast discarded concrete. In particular, there is a problem in that it is extremely difficult to locate a streak position in a narrow place after assembling the formwork and to insert the streak.
In addition, if the streak is incorrectly positioned, it takes time and effort to repair the streak, which is not preferable in terms of construction quality.

[0004] It is conceivable to avoid the above-mentioned problem by making the form bottom double, but there is another problem that it takes time for carpenters and time for dismantling the forms, thereby increasing the cost. Cause problems.

It is an object of the present invention to provide a low-cost, high-precision construction of a reinforcing bar for a non-bearing wall, which is to be post-constructed by a ground foam method.

[0006]

A feature of the present invention for solving the above-mentioned problems is a method of constructing a reinforcing bar for a non-bearing wall in the ground foam method, and constructing a skeleton to which the non-bearing wall is to be attached. Sometimes a flat bar is positioned and fixed on discarded concrete that is cast prior to the reinforcing work, and anchor bars for fixing the skeleton in the flat bar are welded to the flat bar. Is fixed by welding.

[0007] A flat bar to which the anchoring bar for fixing the inside of the skeleton is welded and positioned after the marking on the cast-out discarded concrete can be provided so as to be exposed on the lower surface of the skeleton. The reinforcement for the non-bearing wall can be easily attached to the exposed flat bar by welding, thereby improving the construction accuracy of the reinforcement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an explanatory view for explaining an example of an embodiment in which a reinforcing bar for a non-bearing wall of the ground foam method is provided below a beam by the method of the present invention.

In FIG. 1A, reference numeral 1 denotes a ground, and a portion for constructing a skeleton including a beam portion is excavated to form a space 2 having a desired shape. The excavated surface 2A on which the skeleton is to be constructed is leveled, the discarded concrete 3 is cast, and the formwork 4 is constructed.
Then, after marking on the discarded concrete 3, the flat bars 5, 6 are laid on the discarded concrete 3 along the longitudinal direction of the beam portion, and fixed to the discarded concrete 3 by nailing.

After that, when the beam reinforcing bars 7 are constructed, a plurality of anchor bars 8 for fixing in the beams are SAP-welded to the flat bars 5 and 6 at appropriate intervals in the longitudinal direction of the flat bars 5 and 6. I do. Thereafter, concrete of the skeleton is cast and a skeleton 10 including the beam 9 is constructed on the ground 1 (see FIG. 1B).

When the lower part of the skeleton 10 is excavated to remove the discarded concrete 3 and the formwork 4 and the lower part of the skeleton 10 is exposed, as shown in FIG. A plurality of reinforcing bars 11 used for attaching a non-bearing wall (not shown) to the beam 9 in post-installation are fixed to the lower surfaces of the flat bars 5 and 6 fixed by SAP welding. The mounting position of the streak 11 corresponds to the mounting position of the wall bar 8 welded to the flat bars 5 and 6 first.

As described above, after the discarded concrete 3 is cast in advance and the ink is printed, the flat bars 5 and 6 for anchors are set and fixed, and buried in the beam 9 of the skeleton 10 using the anchor bars 8, and Since the reinforcing bars 11 are welded to the flat bars 5 and 6 exposed on the lower surface of the beam 9, the construction is simple, and the construction accuracy of the reinforcing bars 11 can be significantly increased without increasing the cost. In addition, since it is not necessary to rectify the streaks, the construction quality is improved.

[0014]

According to the present invention, as described above, a flat bar for an anchor is set and fixed after rubbing out concrete, and then buried in a skeleton using an anchor bar. Since the rebar is welded to the flat bar exposed on the lower surface of the skeleton, the construction is simple and the rebar construction accuracy can be significantly increased without increasing the cost. In addition, since it is not necessary to rectify the streaks,
Construction quality is improved.
