When constructing underground beams with a beam length of 2 meters or more, there are various problems such as the need for a large amount of temporary materials to construct the reinforcing bars on-site, and the labor required to assemble the reinforcing bars. Ta. Therefore, there is a construction method that uses prefabricated mesh reinforcing bars and uses the rigidity of the freestanding mesh reinforcing bars to hold each reinforcing bar, for example, in Japanese Patent Publication No. 61-14294,
This is disclosed in Publication No. 14295, etc.

In this invention, a reinforcing bar assembly column is installed on the foundation, upper main reinforcing bars are arranged on the arm rod at the top of this column, and then a plurality of abdominal bars are provided on the side braces to which the lower braces are continuous. A first mesh reinforcing bar is installed by locking it to the upper main reinforcing bar at the upper part of the side strut, and a lower main reinforcing bar is installed at the lower strut of the first mesh reinforcing bar, and then the lower main reinforcing bar is installed at the side part where the upper strut is continuous. This is a method of constructing a reinforced concrete underground beam in which a second mesh reinforcing bar, in which a plurality of abdominal bars are provided on the stirrup, is fixed and installed on the upper main reinforcing bar at the upper mast.

る。 A reinforcing steel assembly column 1 is installed on a base A made of waste concrete, etc., and an arm rod 1 at the top of this column 1 is installed.
Arrange the upper main reinforcing bars 2 on top a. (See Figures 1 and 2) Next, the first mesh reinforcing bar 3, which has a plurality of abdominal reinforcements 3c provided on the side strap 3b where the lower strap 3a is continuous, is attached to the upper main reinforcing bar at the upper part of the side strap 3b. At the same time, the lower main reinforcing bar 4 is installed on the lower mast 3a of the first mesh reinforcing bar 3. (See Figures 3 and 4) Next, the second mesh reinforcing bar 5, which has a plurality of abdominal reinforcements 5c provided on the side mast 5b to which the upper slurp 5a is continuous, is placed on the upper main reinforcing bar 2 at the upper slurp 5a. Lock and install. (See FIG. 5) Then, the stopper bars 6 are attached to the abdominal muscles 3c, 5c of the side stirrups 3b, 5b of the first and second mesh reinforcing bars 3, 5. (See Figure 6) Once the reinforcement for the underground beam is completed in this way,
Construction of the underground beam is completed by installing formwork around it, pouring concrete, and removing the mold after solidification. (Not shown) [Effects of the Invention] According to the construction method of the present invention, only the pillars supporting the upper main reinforcing bars can be used as temporary construction materials. In addition, the reinforcement for underground beams can be assembled by simply installing the first and second mesh reinforcing bars, which are prefabricated with starp bars and abdominal bars, on this column, and installing the lower main reinforcing bars on these mesh reinforcing bars. I can do it.
そのため地中梁の施工時間を短縮することがで
きると共に、施工費用を安価にすることができ
る。 Therefore, the construction time for underground beams can be shortened, and construction costs can be reduced.
