Description

[Detailed Description of the Invention] This was manufactured in a factory, and a beam was assembled on site and a wall was cast on the bottom of the beam, but in this case, as shown in Figure 7, a Frame the roof frame for the wall (however), open the upper end of the formwork ■, attach an auxiliary formwork plate (O) diagonally to the opening for the concrete pouring frame, and insert this auxiliary formwork plate (O) into the opening. Frame board (wall by pouring concrete from the opening of O)
It forms the

Therefore, the extra inside of the auxiliary formwork plate ρ =/IJ-)
It had drawbacks such as the need to hack and finish the (hatched area).

Currently, beams with slits are being manufactured at the factory.

However, when manufacturing beams with slits, a construction method is used in which horizontal reinforcement is raised vertically upwards, concrete is poured to form the beam, and after curing, the slit frame is bent and reinforcement is placed. This method has drawbacks such as the fact that it is difficult to bend the objects.

The present application was invented in view of these shortcomings, and to explain its embodiment now, a rectangular librus cylindrical frame (5) with an open top and a bottom is spaced at regular intervals into a lower formwork (3
) After arranging on top of the librus cylindrical frame (5) and outer formwork (1)
This is made by pouring concrete (6) in between.

When concrete (6) is poured, the concrete will protrude a little from the small hole of Ribras, but since Ribras is used for this purpose, there is no problem.
) and the wall concrete more firmly. When it's necessary, I'm there.

Therefore, after installing the beam (8) manufactured as described above (see Figure 3) between the columns, a wall formwork (9) is framed at the bottom of the beam (8), and concrete αl is poured through the slit (2). It is made by pouring.

As mentioned above, on the bottom frame plate of the external deaf frame for beams with the upper part open, a lower formwork for a punching hole is formed at intervals of a constant length in the longitudinal direction, and the lower formwork is located between the width of the punching hole and the width of the punching hole. The rectangular Libras cylindrical frames with open top and bottom are arranged at regular intervals on the lower formwork, and then concrete is poured between the outside of the Libras cylindrical frame and the inside of the outer form. It has the characteristics that it can be formed by combining various things.

[Brief explanation of the drawings] Fig. 1 is a cross-sectional view of the beam construction, Fig. 2 is a perspective view of the librus cylindrical frame, Fig. 3 is a perspective view of the completed beam, Fig. 4 is the same plan view, and Fig. 5 is a perspective view of the completed beam. The figure is a side view of the same, FIG. 6 is a sectional view of wall construction, and FIG. 7 is a sectional view of the conventional construction method.

Claims (1)

[Claims] (1) On the bottom frame plate of the outer formwork for beams with the upper part open, a lower formwork for punching holes that is low and has the same width as the punched hole width is installed at regular intervals in the longitudinal direction or at regular intervals along the length. After the beam main reinforcements, which are provided over the entire length of the direction and are formed in a rectangular shape on the lower formwork, are erected at regular intervals, and the rectangular librus cylindrical frames with the top and bottom open are arranged at regular intervals on the lower formwork. A method for manufacturing a beam for pouring wall concrete from a beam slit, characterized by pouring concrete between the outside of a librus cylindrical frame and the inside of an outer formwork.
