Base plate detachable PC modular structure {Precast Concrete Modular Structure}

The present invention relates to a PC modular structure with a separate floor plate, and more particularly, a box-type unit PC modular structure is manufactured by combining a separately manufactured floor plate with an inverted U-shaped body part in which a ceiling plate and two side plates are integrally manufactured. It relates to a PC modular structure with a detachable bottom plate that is advantageous for demolding during manufacture and minimizes a lifting load.

It started with PC (Precast Concrete) of columns and beams forming the structure of the building in 1988. Currently, the Singapore government mandates that more than 65% of the structure of a building be made of PC, and in the 2000s, PBU (factory-made prefabricated toilet unit; Prefabricated Bathroom Unit) is activated, and bathrooms in buildings are currently being constructed with 100% PBU.

Therefore, in recent years, concrete PC units have been manufactured in the form of boxes so that they can be freely inserted or removed into or removed from the frame for wall-type structures or for ramen structures, and to be utilized for both remodeling and new construction/extension of buildings.

However, the conventional box-type PC unit is not only very difficult to demold because it has to install a mold inside and demold when producing a box-shaped closed section, but also increases the lifting load when lifting due to the heavy weight of the PC unit itself. there was a problem with

It consists of a bundle 142 and a fixing member 143 joined so as to partially protrude from the coupling plate 141, and an end coupling hardware on the edge beam 13 so that the coupling hole 141a is exposed in the end coupling groove 132. 14 are each configured to be embedded.

The nut bundle 142 has a nut groove formed therein so that the bolt is fastened, and the fixing member 143 may be made of an iron wire, a stud, etc., and the fixing member 143 is embedded in the edge beam 13 . It may be formed to be fixed or to be embedded in the side plate 12 and the edge beam 13 at the same time, and the shape may be a straight line or a bent form.

As described above, a separately manufactured bottom plate 20 is coupled to the lower portion of the body portion 10 made of an inverted U shape.

The bottom plate 20 is formed in a plate shape of a predetermined thickness to close the lower portion of the body portion 10 .

To explain in more detail, the bottom plate 20 is formed with a bottom part 21 having a plate shape of a certain thickness, and is formed higher than the height of the bottom part 21 around the outer periphery of the bottom part 21 and consists of a rim beam 23, To be coupled to the lower portion of the inverted U-shaped body portion (10).

The edge beam 23 forms a thin thickness of the bottom portion 21 while reinforcing the strength, and is blocked out to a predetermined depth on both ends in the longitudinal direction to form an end fastening groove 231 with the body portion 10 . To provide a bonding surface for bonding.

The edge beam 23 is said to be coupled in contact with the edge beam 13 of the main body 10 , so that the edge beam 23 of the bottom plate 20 is also configured with an end coupling hardware 24 .

The end coupling hardware 24 has the same configuration as the end coupling hardware 14 that is embedded in the body portion 10, and the coupling plate 241 through which the coupling hole 241a is formed in a plate shape of a predetermined size, and the coupling plate It consists of a nut bundle 242 configured under the fastening hole 241a of the 241 and a fixing member 243 joined to partially protrude from the coupling plate 241 .

The end coupling hardware 24 is such that the end coupling hardware 24 is embedded in the edge beam 23 so that the coupling hole 241a is exposed in the end coupling groove 231, as in FIGS. 3 and 4, The end coupling hardware 14 of the main body 10 and the end coupling hardware 24 of the bottom plate 20 are positioned on the same line and welded or bolted 40 using a separate cover plate 30 on the upper part. Alternatively, the bolt 40 is fastened and then welded to be coupled to the body portion 10 .

In this way, the body portion 10 and the bottom plate 20 are bonded using the cover plate 30 to make bonding very easy.

The protruding ribs 27 are formed on the upper surface of the bottom plate 20 so as to protrude upward, so that the bottom plate 20 can be reinforced, and the protruding ribs 27 are the width of the bottom plate 20 . The first ribs 271 and the second ribs 272 may be respectively formed in the longitudinal direction of the bottom plate 20 by being spaced apart by a predetermined distance in the direction.

In particular, in the protruding rib 27 , the first rib 271 is formed in the entire longitudinal direction of the bottom plate 20 , and the second rib 272 is a predetermined distance inward from one end of the bottom plate 20 . It is formed only from the spaced apart point to the other end, and the reinforcing rib 273 is formed so that both ends in a right angle direction from one end of the second rib 272 connect the first rib 271 and the edge beam 23, respectively. Thus, the first rib 271, the reinforcing rib 273, and the reinforcing rib is not formed in the space made of the edge beam 23, so that the facility and the piping can be facilitated.

In this way, by forming a separate space in which the reinforcing rib is not formed, it is possible to form a separate space, such as a toilet, which requires facilities and piping when forming a unit structure.
