Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slab foundation, and more particularly to a foundation slab concrete and a slab concrete cast in the foundation beam concrete. About. 2. Description of the Related Art In a slab foundation as described above, a reinforcing bar of a foundation beam is formed as a unit in which a stap reinforcing bar arranged at intervals in the longitudinal direction of the foundation and a transverse bar in the longitudinal direction of the foundation are integrally connected. After the beam reinforcement unit is carried into the site and installed, slab reinforcement is arranged between the beam reinforcement units. In this case, the stirrup streaks are calculated by calculating the required number per unit length by structural calculation, and are arranged at well-cut dimensional intervals so as to satisfy the required number. The horizontal streak of the slab portion is inked out to the concrete discarded in advance in the slab portion, and is arranged according to the inked reference black. As described above, in the related art, the positions of the stirrups are arranged at appropriate dimensional intervals, and the positions of the stirrups do not always correspond to the positions of the horizontal slab streaks. Therefore, the slab streaks are inked out on the discarded concrete as described above, and are installed in accordance with the position of the inking, so that there is a disadvantage that the work is so complicated and time-consuming. The slab horizontal streaks are arranged in upper and lower two rows, and the upper horizontal streaks must be installed while looking from above when aligning with the reference black mark displayed on the discarded concrete. In particular, such a positioning and setting operation of the reinforcing bars is a work in the middle waist, and has a drawback that the position is likely to be out of order. [0005] Further, since the stap bars are installed at different positions in the longitudinal direction for each foundation beam concrete, for example, when it is necessary to open a pipe opening or the like after placing the foundation concrete, the stap bars are left as they are. Since it is not possible to check the position of the stap streaks, the work must be performed after checking the position of the stap streaks using a reinforcing bar sensor or the like, and since it is not known where such stap streaks come, There is a problem that a prior piping plan becomes difficult. SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, facilitates the work of arranging the horizontal bars of the slab, and provides an opening for installing a piping sleeve that penetrates the foundation beam. It is an object of the present invention to provide a slab foundation reinforcing structure that can easily carry out planned construction by avoiding stirrups of a beam and that can easily form such openings after construction. [0007] In order to solve the above-mentioned problems, according to the present invention, in a beam reinforcing unit provided with stirrups arranged at intervals in a longitudinal direction of a foundation beam, the stirrups are provided. together they are arranged at equal intervals combined basic module of a building the size position relative units, slabs horizontal stripes disposed between the beam muscles unit, the static
A pair of lap studs spaced apart in the transverse direction
Are arranged so as to straddle between the vertical streaks . The stirrup is installed in accordance with the basic module of the building, and the horizontal streaks of the slab foundation can be arranged in accordance with the position of the installed stap. In the drawings, (1) shows a reinforcing bar unit of a foundation beam, and this reinforcing bar unit (1) has a loop shape formed in a substantially rectangular shape when viewed from the cross section of the foundation beam. … And a plurality of horizontal streaks (3) (3) ... in the longitudinal direction of the foundation beam. The stapling bars (2) are arranged at intervals in the longitudinal direction of the foundation beam. A horizontal bar (3) is integrally connected so as to connect the inside of each corner of the stirrup bar (2). Such a unit (1) is installed along the longitudinal direction of the foundation beam, and At this time, the stirrups (2) (2) are arranged along the module cores P, P.
Are arranged at equal intervals in accordance with the position of. The module interval is, for example, about 310 mm. (4) in FIG.
Is concrete discarded on split stone (5),
Spacer block (6) on this discarded concrete (4)
And the reinforcing bar unit (1) of the foundation beam is mounted on the spacer block (6).
Is installed. (8) An upper horizontal bar for a foundation slab concrete (9) cast between the foundation beams, (10)
Also shows the lower horizontal line. These horizontal streaks (8)
(10) is cut in advance to a predetermined length that can be installed between the foundation beams, and these horizontal streaks (8) and (10) are installed at predetermined intervals and heights on site, respectively. A pair of stair bars (2) in the reinforcing bar unit (1) of the beam section
By this <br/> and be disposed along allowed to straddle between vertical stripe portion (2a) (2a), so as to follow these lateral stripes (8) (10) to the module core P, accurately positioned Can be installed. At this time, the lower horizontal line (10) is installed on the spacer block (6), and the lower horizontal line (1) is further mounted.
Another transverse streak (10) perpendicular to 0) is placed on it. On the other hand, the horizontal streaks (8) on the upper side are straddled between the vertical streaks (2a) and (2a) of the stirrup streaks (2), and the horizontal positioning streaks (11) attached to a predetermined height in advance. ) (11) so that it can be positioned and installed at a predetermined height. FIG. 2 (12) shows a column reinforcement unit installed on the column base support, and (13) shows an anchor bolt. As described above, according to the present invention, the stirrup streak of the foundation beam is set in accordance with the module core of the building, and the horizontal streak of the slab foundation also follows the module core. By taking care of the arrangement of the reinforcing bars, it is possible to easily position them without the necessity of marking out, as in the past, when performing the reinforcing work on the horizontal slab bars. it can. And next to the slab
Straddle the muscle between the pair of vertical streaks
The slabs have good parallelism

effective. In addition, the stirrup is installed along the module core of the building, so it is easy to plan the installation of the piping sleeve in the foundation beam where the beam reinforcement unit of the foundation beam is to be installed. Also, since there is always a stirrup streak for each module core, it is only necessary to open the above-mentioned opening avoiding this module core, so that the opening after the foundation concrete is cast can be easily formed. is there.
