Description

Connection structure of modular unit using guide-pin}

The present invention is a guide pin that exhibits sufficient shear force, has excellent resistance to vibration and deflection, and does not require removal of finishing materials during joint construction by joining the horizontal members of the upper and lower modular units to each other using a plurality of guide pins inserted inside the pinhole. This is about the joint structure of modular units using .

Unlike existing buildings where assembly or construction of members is performed on site, modular structure is a structural system that is completed by stacking and assembling modular units pre-manufactured in a box-type factory at the site, up, down, left, and right.

In this modular system, not only the structural frame, but also various interior and exterior materials, mechanical equipment, and electrical wiring processes are mostly carried out in the factory, so excellent quality can be secured and construction period can be greatly shortened by minimizing field processes.

In particular, in apartment complexes, the floor plan of each unit is kept the same, so construction is repeated on each floor using large forms such as gangforms, while the rooftop floor has a different plan shape from the lower unit, making it impossible to construct large forms, so it must be used with conventional forms. It is mainly constructed using the RC method. However, it is difficult to secure quality with this conventional construction method, and since the rooftop floor is constructed at the end of the frame construction, construction is difficult due to limitations in the supply of on-site manpower and the use of equipment such as tower cranes. Accordingly, demand for modular systems is increasing.

The modular unit that makes up the modular system is usually shaped like a hexahedron and has vertical members at each corner, and the top and bottom of the vertical members are connected by horizontal members, respectively.

These box-shaped modular units are brought into the site and connected to each other by bolting the vertical members of modular units adjacent to each other up and down or left and right.

In the past, four unit modules were installed adjacent to each other, and a connection shear plate through which guide bolts protruding from the top of each pillar was installed on the top of the pillar to fix the adjacent unit modules to each other. The unit modules installed at the top were also fixed to each other using the above-described guide bolts (Patent No. 10-1031299).

However, in this modular structure, since the upper and lower modular units are joined only to vertical members, it is difficult to exert sufficient shear force at the joint when lateral force is applied to the modular structure, so there is a limit to resistance to lateral force. In addition, the rigidity of the horizontal members supporting the floor slab is not high, so there is a risk of serviceability being reduced due to excessive vibration or deflection.

In order to solve the above problems, the present invention seeks to provide a joint structure of modular units using guide pins that can exert sufficient shear force by joining the horizontal members of the upper and lower modular units to each other using guide pins.

The present invention seeks to provide a joint structure of modular units using guide pins that has excellent resistance to vibration and deflection and does not require removal of finishing materials during joint construction.

The present invention according to a preferred embodiment includes vertical members provided at four corners to be spaced apart from each other, a plurality of upper horizontal members connecting the upper ends of neighboring vertical members, a plurality of lower horizontal members connecting lower ends of neighboring vertical members, and a plurality of horizontal members. It is for assembling a plurality of modular units consisting of a bottom plate provided inside the lower horizontal member by stacking them vertically. A plurality of guide pins are protruding from the upper surface of the upper horizontal member of the lower modular unit, and the upper modular unit A joint structure of a modular unit using a guide pin is provided, wherein a pin hole into which the guide pin is inserted is formed in the lower horizontal member.

In the present invention according to another preferred embodiment, the lower horizontal member is composed of a lower flange, an upper flange, and a web connecting ends of the upper and lower flanges and has a U-shaped cross section with an open inside, and the bottom plate has an end of the lower horizontal member. It is provided inside the guide, wherein the pinhole is formed to penetrate the lower flange and the bottom plate of the lower horizontal member and communicate with the upper flange of the lower horizontal member or the upper surface of the bottom plate, and the inside of the pinhole is filled with a filler.

And Figure 3 is a perspective view showing the coupling relationship between the horizontal members of the upper and lower modular units by guide pins, and Figure 4 is a perspective view showing the guide pin inserted into the pinhole.

As shown in Figures 1 to 4, the joint structure of the modular unit using the guide pin of the present invention includes vertical members 2a and 2b provided at four corners to be spaced apart from each other, and the upper ends of neighboring vertical members 2a and 2b. A plurality of upper horizontal members (3a, 3b) connecting, a plurality of lower horizontal members (4a, 4b) connecting the lower ends of neighboring vertical members (2a, 2b), and a plurality of lower horizontal members (4a, 4b) inside It is for assembling a plurality of modular units (1a, 1b) composed of bottom plates (5a, 5b) by stacking them vertically, and a plurality of guides are provided on the upper surface of the upper horizontal member (3a) of the lower modular unit (1a). A pin 6 is formed to protrude, and a pin hole 7 into which the guide pin 6 is inserted is formed in the lower horizontal member 4b of the upper modular unit 1b.

The present invention is a guide that exhibits sufficient shear force by joining the horizontal members of the upper and lower modular units (1a, 1b) to each other by the guide pin (6), has excellent resistance to vibration and sagging, and does not require removal of finishing materials during joint construction. This is to provide a joining structure for modular units using pins.

The modular structure to which the present invention is applied can be used in various buildings such as residential houses, school facilities, various lodging facilities, officetels, and temporary disaster facilities as well as rooftop structures.

The modular units (1a, 1b) include four vertical members (2a, 2b), upper horizontal members (3a, 3b) connecting the upper parts of neighboring vertical members (2a, 2b), and neighboring vertical members (2a, 2b). ) is composed of lower horizontal members (4a, 4b) connecting the lower part of the cuboid and forms a rectangular parallelepiped shape.

Bottom plates (5a, 5b) are provided inside the plurality of lower horizontal members (4a, 4b).

The ends of the upper horizontal members 3a, 3b or the lower horizontal members 4a, 4b may be provided with horizontal connectors for coupling each horizontal member to the side of the vertical members 2a, 2b.

When stacking the upper and lower modular units (1a, 1b), the upper horizontal member (3a) of the lower modular unit (1a) and the lower horizontal member (4b) of the upper modular unit (1b) are fixed to each other by a plurality of guide pins (6). do.

For this purpose, a plurality of guide pins 6 are protruding from the upper surface of the upper horizontal member 3a of the lower modular unit 1a, and the guide pins 6 are formed on the lower surface of the lower horizontal member 4b of the upper modular unit 1b. ) A pinhole 7 is formed at a position corresponding to ) and the guide pin 6 is inserted into the pinhole 7.

Since the guide pins 6 can be freely installed in the required number at any point of the horizontal member in consideration of the size of the lateral force, etc., sufficient shear force can be exerted at the joint of the upper and lower modular units 1a and 1b.

The horizontal member is provided in both x and y directions on a plane. Therefore, the horizontal members in each direction are supported by the guide pins (6) and can exert sufficient support against two-way lateral forces.

In addition, when the upper and lower modular units (1a, 1b) are previously joined by bolting, the ceiling finishing material of the lower modular unit (1a) or the floor finishing material of the upper modular unit (1b) must be removed or left in an unconstructed state for bolting. Post-construction had to be done after joining the upper and lower modular units (1a, 1b). In contrast, in the present invention, the upper and lower modular units 1a and 1b are joined by the guide pin 6 and the pinhole 7, so there is no need for a finishing material removal process, thereby improving constructability.

The guide pin 6 may be welded to the upper surface of the upper flange 32 of the upper horizontal members 3a and 3b, or may be tapped and screwed to the upper flange 32. Alternatively, it is also possible to bolt the guide pin (6) to the upper flange (32) using a one-way bolt method.

As shown in FIGS. 3 and 4, a protection panel 9 is provided between the upper horizontal member 3a of the lower modular unit 1a and the lower horizontal member 4b of the upper modular unit 1b, The guide pin (6) may penetrate the protection panel (9) and be inserted into the pinhole (7).

When installing a connection plate on the upper part of a neighboring vertical member to connect laterally neighboring modular units, the lower modular unit 1a and the upper modular unit 1b are spaced apart from each other by the thickness of the connection plate.

In this case, the upper surface of the upper horizontal member 3a of the lower modular unit 1a and the lower surface of the lower horizontal member 4b of the upper modular unit 1b are exposed, so separate fire resistance treatment must be applied to these parts.

Additionally, if the spacing between the guide pins 6 is large, sagging may occur in the upper horizontal members 3a and 3b.

Therefore, in order to solve this problem, the protection panel 9 can be installed between the upper horizontal member 3a of the lower modular unit 1a and the lower horizontal member 4b of the upper modular unit 1b.

At this time, the guide pin 6 may penetrate the protection panel 9 and be inserted into the pinhole 7 of the lower horizontal member 4b.

The protection panel 9 may be made of a non-combustible material with excellent fire resistance. For example, it is possible to use mineral fiber board that has excellent heat resistance and is lightweight.

The protection panel 9 can be pre-assembled when manufacturing the modular units 1a and 1b. However, when the protection panel (9) is installed at the lower part of the upper modular unit (1b), there is a risk of damage during transportation and loading of materials, so the protection panel (9) is attached to the upper horizontal member (3a) of the lower modular unit (1a). Pre-assembly on the upper surface is preferable.

In this case, if the base portion 62 of the guide pin 6, which will be described later, is supported by hanging on the upper surface of the protection panel 9, the protection panel 9 can be fixed without a separate fastening member.

Figure 5 is a perspective view showing a state in which the inside of a pinhole is filled with a filler, and Figure 6 is a cross-sectional view showing embodiments of the pinhole.

As shown in FIGS. 5 and 6, the lower horizontal members 4a and 4b include a lower flange 41, an upper flange 42, and a web 43 connecting ends of the upper and lower flanges 41 and 42. It has a U-shaped cross section with an open inside, and the bottom plates (5a, 5b) have ends provided inside the lower horizontal members (4a, 4b), and the pinholes (7) are located at the lower horizontal members (4a, 4b). It is formed to communicate with the upper flange 42 of the lower horizontal member 4a, 4b or the upper surface of the bottom plate 5a, 5b through the lower flange 41 and the bottom plate 5a, 5b, and the pinhole ( 7) It may be configured to be filled with filler 8 inside.

The guide pin 6 can be inserted and fixed into the pinhole 7 using an interference fit method. However, in this case, the guide pin 6 may fall out of the pinhole 7 due to external force, so the vertical joining of the upper and lower modular units 1a and 1b is weak.

Therefore, a mortar inlet communicating with the pinhole 7 is formed on the upper part of the pinhole 7, and the filler 8 is filled into the pinhole 7 into which the guide pin 6 is inserted through the mortar inlet, thereby forming the guide pin 6. ) can be fixed to the upper modular unit (1b).

At this time, the lower horizontal members (4a, 4b) can be formed with a U-shaped cross section with an open inside so that a form such as a deck plate for concrete pouring of the floor plates (5a, 5b) can be mounted.

For manufacturing and management efficiency, the upper horizontal members (3a, 3b) can also be formed with the same cross-section as the lower horizontal members (4a, 4b). That is, the upper horizontal members (3a, 3b) are also composed of the lower flange (31), the upper flange (32), and the web (33) connecting the upper and lower flanges (31, 32) to form a U-shaped cross section with an open inside. You can.

The bottom plates (5a, 5b) are provided inside the lower horizontal members (4a, 4b) arranged in a square shape in plan view. Therefore, the bottom plates (5a, 5b) serve as diaphragms of the frame by the lower horizontal members (4a, 4b) to improve resistance to lateral force.

The pinhole 7 may be formed to penetrate the lower flange 41 of the lower horizontal members 4a and 4b and communicate with the inside of the bottom plates 5a and 5b.

The mortar injection port may be formed to extend from the pinhole 7 and penetrate the upper flange 42 of the lower horizontal members 4a and 4b (FIG. 6(a)). In this case, the pinhole 7 can be formed in a straight line in the vertical direction.

If interference occurs because the interior and exterior materials for forming a wall are pre-assembled on the upper part of the lower horizontal members (4a, 4b), the mortar inlet is bent toward the inner floor plates (5a, 5b) and not toward the lower horizontal members (4a, 4b). It can be configured to allow injection of the filler 8 from the top of the bottom plates 5a and 5b (Figure 6(b)). In this case, the pinhole 7 may have a bent shape rather than a straight shape.

Although not shown in the drawing, when the dry wall is pre-assembled on the upper part of the lower horizontal members 4a and 4b, the mortar injection hole is drawn through the dry wall to the upper surface of the upper horizontal members 3a and 3b to form the modular unit 1a, It may be configured to enable injection of the filler 8 from the top of 1b).

The mortar injection port can be formed by installing an injection pipe (not shown) such as a PVC pipe or flexible pipe in advance before pouring concrete into the floor plates 5a, 5b, and then pouring concrete into the floor plates 5a, 5b.

The filler 8 filled inside the pinhole 7 may be mortar, epoxy, etc.

The guide pin (6) is fixed to the lower horizontal members (4a, 4b) and the bottom plates (5a, 5b) by a filler (8) such as mortar filled inside the pinhole (7). Therefore, vibration and deflection of the horizontal members can be minimized by the upper and lower horizontal members 3a, 3b, 4a, and 4b operating as one.

In addition, since the guide pin (6) is embedded within the filler (8), separate fire resistance treatment is not required.

Figure 7 is a perspective view showing an embodiment of a guide pin.

As shown in FIGS. 6 and 7, a head portion 61 with an enlarged diameter may be formed at the upper end of the guide pin 6.

A head portion 61 with an enlarged diameter is formed at the top of the body portion 63 of the guide pin (6) so that the guide pin (6) is firmly anchored inside the filler (8) filled inside the pinhole (7). You can.

The head portion 61 is physically engaged with the filler 8 inside the pinhole 7, so that the guide pin 6 can be firmly fixed inside the bottom plates 5a and 5b.

A base portion 62 that is inserted into the lower part of the pinhole 7 may be formed at the lower portion or middle of the guide pin 6.

The head portion 61 and the base portion 62 may be formed in the shape of a truncated cone whose diameter decreases toward the top to facilitate entry into the pinhole 7.

The base portion 62 has a lower diameter to prevent flow from occurring after being inserted into the pinhole 7, and to prevent the filler 8 from flowing out after filling the inside of the pinhole 7. It is desirable to form it to have the same size as the inner diameter of the pinhole (7).
