[0028] The basement member according to the present invention can be applied to the construction of a prefabricated basement without a dry moat. Sometimes it happens.

[0029]

[Effect of the idea]

The present invention has the following excellent effects. The basement member according to the present invention has a large protrusion that functions as a large pull on the upper surface of the bottom plate. It is equipped in one piece. Therefore, when constructing the floor of the basement itself, it is possible to omit the installation of large drawers. The floorboards can be immediately installed by placing the joists on the large extensions. Ru. Therefore, it is possible to improve the efficiency of floor construction after constructing the basement itself, and Combined with the fact that the main body of the room is prefabricated, it is possible to improve the construction efficiency of the basement as a whole. .

[0030] The top surface of the large extension is one step higher than the top surface of the bottom plate of the basement member, so the floor Even if condensation occurs in the space below, the joists are less susceptible to the effects of condensation, creating a stable floor. can be achieved.

[0031] The basement member according to the present invention is configured to have a U-shape with an open upper end. When assembled, the weight is reduced compared to the conventional rectangular tube-shaped member shown in Fig. 15. This makes it easier to handle the parts during transportation and assembly.

[0032] In order to adopt a structure in which the upper end opening of the basement member is closed with a separate lid member, Therefore, the upper end opening of multiple connected members can be closed with a single lid member. becomes. Therefore, when providing an entrance/exit opening in the ceiling of a basement, the size of the opening must be The opening has a greater degree of freedom than conventional methods in terms of the area where it is formed, and it also has a stable opening. can be formed. For example, as shown in Figure 1, a large Even large entrance/exit openings can be stably formed.

[0033] In addition, since the basement members are U-shaped or box-shaped with an open top, the bottom Even if a large protrusion is formed on the plate, the mold structure is simple and the manufacturing of the part is difficult. Easy to make.

[0034] Especially when the inner surfaces of the opposing side panels of the basement member are formed as vertical surfaces. As shown in Figure 10, the ceiling can be formed as a flat surface. Also, the ceiling space formed by installing ceiling panels (the gap in the space is usually 10 cm) ), including its edges, for piping, etc. be able to.

[0035] By the way, the connecting part between the side plate and the top plate was formed as an inclined surface A, as shown in Fig. 16. Construct a basement using the conventional square tube-shaped basement component (intermediate member a) shown in In this case, the gap in the ceiling space was relatively small, usually around 10 cm. , both edge parts B and B of the ceiling of the constructed basement were sloped along this slope A. The ceiling of the basement had to be finished to look good. There was no problem. Also, the end of the ceiling space, which is a convenient place for piping, can be used effectively. There was a problem that made it impossible to utilize it.

[0036] The large protrusion provided on the bottom plate of the basement member is a protrusion extending in the width direction of the bottom plate. When a drainage ditch is formed between adjacent large spaces, each basement member The drainage ditch will be connected in the direction of connecting the basement members, and the end will open into the dry moat. do. Therefore, after the construction of the basement itself and before finishing the interior of the room such as the floor, If the condensed water that adheres to the wall of the main body flows down, drain the condensed water from this communication state. This means that the water can be discharged sequentially from the water ditch to the dry moat.
