6 is a flow chart of a wet lintel manufacturing method using a wet lintel manufacturing apparatus according to an embodiment of the present invention, and FIG. 7 is a flow chart of forming steps in the wet lintel manufacturing method using a wet lintel manufacturing apparatus according to an embodiment of the present invention.

Hereinafter, the wet lintel manufacturing method using the wet lintel manufacturing apparatus according to the present embodiment will be described in detail with reference to FIGS. 1 to 7.

As shown in FIG. 6, the wet lintel manufacturing method according to this embodiment mainly includes the steps of preparing concrete mortar and locking the forming mold 100 on the excitation unit 200 (S100); Injecting concrete mortar into the molding mold 100 and molding it (S200); Flattening (S300); Removing the separation partition member 130 and the spacing member 140 after 1 hour to 2 hours have elapsed (S400); And it may include a curing step (S500) of exposing to steam and curing naturally.

First, a step of preparing in advance may be performed (S100). That is, prepare the concrete mortar and place the molding mold 100 on the top of the unit 200 using a forklift, and fasten the locking hook part 320 to the locking ring 310 to have the molding mold 100 It can be locked onto the unit 200.

Next, a step of molding by injecting concrete mortar into the molding mold 100 may be performed (S200).

The molding step (S200), as shown in FIG. 7, mainly includes: injecting 40% of the concrete mortar while driving the excitation unit 200 for 20 seconds (S210); removing air bubbles by driving the excitation unit 200 for 10 seconds (S220); Installing the separation partition member 130 on the mold plate 110 and coupling the gap maintaining member 140 (S230); and injecting 100% of the concrete mortar while driving the excitation unit 200 for 20 seconds (S240); A step (S250) of removing air bubbles by driving the excitation unit 200 for 10 seconds may be included.

More specifically, the step (S210) of injecting 40% of the concrete mortar while driving the excitation unit 200 for 20 seconds is performed.
Right after the concrete mortar is added, the U-shaped steel can be inserted (S211). At this time, the inserted section may be a single piece of U-shaped section.

Thereafter, a step of removing air bubbles by driving the excitation unit 200 for 10 seconds may be performed (S250). In this case, compared to the conventional dry method, the density and specific gravity of the fabricated lintel tissue may be increased, and thus structural rigidity may be increased.

Next, a planarization step may be performed (S300). As a result, the finishing treatment can be smoother in the case of wet-type lintels compared to dry-type ones.

Next, after 1 hour to 2 hours have elapsed, a step of removing the separation partition member 130 and the space maintaining member 140 may be performed (S400).

Finally, a curing step of exposure to steam and natural hardening may be performed. The curing step may be a step of naturally curing for 8 to 9 hours after supplying steam at 50 to 60° C. for 1 to 2 hours (S500).

Through these steps, compared to the conventional dry method, it is easy to insert the shape steel into the lintel, the outer finish is excellent, the possibility of defects such as cracks is low, and the generation of air bubbles is minimized, so that structural properties can be secured. That is, compared to the conventional dry method, the density and specific gravity of the fabricated lintel tissue can be increased, and thus structural rigidity can be increased.

In addition, even if only one C-shaped steel is disposed within the lintel, sufficient rigidity can be secured, thereby reducing self-load and improving workability.
