Joint structure of housing PC module and construction method of housing PC modular using the joint structure {Joint structure of housing PC module and construction method of housing PC modular using the joint structure}

The present invention relates to a joint structure of a housing PC module and a construction method of a housing PC module using the joint structure, and more specifically, to a joint structure of a housing PC module which vertically joins a reinforcing bar protruding downward from an upper-layer PC module in a vertical direction by inserting it into a sleeve of a lower-layer PC module and integrating it with mortar, and a construction method of a housing PC module using the joint structure.

Most buildings currently being built in Korea are concrete structures or concrete structures based on steel structures. Since most of these buildings are constructed on-site, relying on skilled workers and equipment on-site, there are differences in construction quality and construction period at each site due to various factors such as the skill level of skilled workers, environmental conditions at the site, climate change, material supply status, and supervisor capabilities. Recently, various types of buildings are being widely applied thanks to continuous technological development of industrialized construction technology based on factory production, centered around the U.S., Europe, and Japan. In particular, the application cases of modular buildings using modular construction methods are increasing significantly.

Modular construction refers to a construction method in which modular units are manufactured in a factory, and various interior and exterior materials, facilities, and wiring are constructed in advance, and then transported to the site and assembled and laminated, unlike the existing wet construction method in which construction is done on site. Therefore, modular houses are houses built by applying the modular construction method described above. Conventional modular houses using the modular construction method have been using modules that are approximately 6 m long due to the weight of the concrete module. In addition, the ramen method is used to complement the shortcomings of houses using the conventional wall-type method. However, when using this ramen method to manufacture PC modular houses, there is a disadvantage in that the number of modules increases due to strength limitations. In order to solve this problem, it is necessary to improve the joint structure between the modules.

The joint structure (J) of the housing PC modular according to the present embodiment is described as being applied to a duplex house having a symmetrical structure centered on the core portion (9000), as an example. However, the present invention is not limited thereto, and the joint structure (J) of the housing PC modular can be applied to a typical PC modular house, not a duplex house having a symmetrical structure centered on the core portion.

And in Fig. 1, in order to show the internal structure of the lower layer, the illustration of the left upper layer portion including the upper layer 1 PC module (5000), the upper layer 2 PC module (6000), the upper layer 3 PC module (7000), and the upper layer side wall portion (8000) illustrated in Figs. 13 and 14 is omitted. And in Fig. 1, the illustration of the right upper layer portion corresponding to the upper layer 1 PC module (5000), the upper layer 2 PC module (6000), the upper layer 3 PC module (7000), and the upper layer side wall portion (8000) centered on the core portion (9000) is also omitted.

The lower layer first-length direction girder sheath pipe (1140) is arranged so as to be spaced apart from each other in the longitudinal direction of the lower layer first-length direction girders (1110). The lower layer first-length direction girder systole (1140) is inserted into the lower layer first-length direction girder (1110) to provide a space in which a PC steel bar (S) for horizontally joining the lower layer first PC module (1000) and the lower layer second PC module (2000) can be inserted into the lower layer first-length direction girder (1110).

The column sheath pipe (1150) of the lower first-way girder is installed to connect the lower first slab portion (1100) and the lower first wall portion (1210). Specifically, the column sheath pipe (1150) of the lower first-way girder is installed to allow the lower first wall portion column reinforcing bar (1221) that is formed by protruding downward from the lower first wall portion (1210) to be inserted and connected. The column sheath pipe (1150) of the lower first-way girder is installed at each of the two width-wise edges of the lower first-way girder (1130).

The lower first wall main body portion (1210) is the central portion of the lower first wall portion (1200). A window is formed in the lower first wall main body portion (1210).

The lower first wall column part (1220) is arranged at an edge portion facing the lower second PC module (2000). Of course, the lower first wall column part (1220) is also arranged at an edge portion facing the core part (9000). The lower first wall column part (1220) has lower first wall column reinforcing bars (1221) arranged inside. In addition, the lower first wall column reinforcing bars (1221) penetrate the column sheath pipe (1150) of the lower first single-way girder of the lower first slab part (1100) and are exposed (protruded) downward. That is, the upper portion of the lower first wall column reinforcing bars (1221) is arranged inside the lower first wall column part (1220), and the lower portion is exposed downward of the lower first wall column part (1220). At this time, mortar may be filled between the lower first wall section column reinforcing bar (1221) and the lower first single-way girder column section sheath (1150). In addition, the lower first wall section column section (1220) is embedded with a lower first wall section sleeve (lower first column sleeve) (1222) so that the upper first wall section column reinforcing bar (5221) exposed in the upper first wall section (5200) can be inserted from the upper top to a position spaced apart by a set length downward from the top. The lower first wall section sleeves (1222) are arranged so that four are spaced apart from each other so that they form a rectangle when connected to each other. The lower first wall section sleeves (1222) are installed in the vertical direction.

In order to prevent the lower layer second wall wire loop (2140) protruding in the direction of the lower layer first wall column (1220) from interfering with the lower layer first wall column (1220) when the lower layer first PC module (1000) and the lower layer second PC module (2000) are joined, a lower layer first wall column groove (1220a) that acts as a shear key is formed in a portion facing the lower layer second wall column (2220).

A plurality of lower first wall portion wire loops (1240) are installed so as to be spaced apart along the height (up and down) direction of the lower first wall column portion (1220). The lower first wall portion wire loop (1240) includes a lower first wall portion wire loop ring (not shown). The lower first wall portion wire loop ring is formed in a structure similar to the lower first slab portion wire loop ring (1171). The lower first wall portion wire loop ring protrudes toward the lower second PC module (2000). That is, one side of the lower first wall body wire loop (1240) is embedded in the lower first wall body column (1220), and the other side of the lower first wall body wire loop ring protrudes toward the lower second PC module (2000).

And in this embodiment, the two lower second longitudinal direction girders (2110) are formed in the same length, for example. At this time, the length of the lower second longitudinal direction girder (2110) is longer than the length of the lower first longitudinal direction girder (1110) among the two lower first longitudinal direction girders (1110).

The lower second slab panel (2120) is formed integrally by arranging lower second longitudinal girders (2110) and lower second single-directional girders (2130) at the edges, and serves as a lower floor in the middle of the lower first PC module (1000) to the lower third PC module (3000).
