PC Double-wall공법 적용을 통한 공동주택 지하주차장 시공 = The construction of an apartment underground parking lot through an application of PC Double-wall

다국어 초록 (Multilingual Abstract)

The underground parking lot of an apartment is normally constructed by using reinforced concrete (RC) construction that is comprised of the rebar and form work however, this RC construction method requires a number of labors always. Therefore, it has been pointed out as a factor to delay the duration of the whole construction frequently.
Precast Concrete (PC) construction method has been used in nowadays in a number of construction sites to solute the problems of RC construction method. PC construction is a type of construction method in which utilizes manufacturing processes normally used for production of consumer goods at factories for mass productions and on-site installations of standardized, high quality structural components. However, this method also has some limitations in terms of its construction characteristic.
In order to solve PC construction problem, many attempts have been made and the PC Double-wall method is a good example. The PC Double-wall is a kind of PC thus, the cross section and rebar details are developed considering PC manufacturing. Particularly, a form system is developed to manufacture thin and hollow core PC wall.
This study therefore, was applied this PC Double-wall method to real construction site and confirmed the characteristics.

The results of this study are summarized as follow:

(1) The PC Double-wall members is produced in the factory and constructed in the construction site. Therefore, it can skip the form work that is characteristic of RC method. Because of this reason, we could confirm the effect of shortening the construction period about 40%.

(2) In case of PC double-wall construction method, labor-intensive structure, which is a characteristic of existing RC construction, can be removed, so that it is possible to cope with delays of construction period more flexibly.

(3) In the case of RC construction, it is necessary to install a scaffolding structure, which may expose it to the risk of safety accidents. However, since the support and scaffold construction are unnecessary in the PC double-wall construction, safety accidents can be prevented.

Through the application of the PC double-wall construction method, it was possible to actively respond to the situation of the construction site where the shortage of technical engineers such as form or rebar work labors.
In addition, when PC double-wall construction method is adopted, it is confirmed that the whole frame of the underground parking lot of apartment house can be converted into PC, which simplifies construction management and improves workability.
