Description

Unit block system {Unit block system}

In the present invention, by combining the lower connector and the upper connector provided to interconnect the horizontal member and the vertical member at the corner of each box-shaped unit block with a guide pin and a fixing bolt, it is easy to combine vertically adjacent unit blocks. It is about a unit block system that can minimize on-site processes.

Unlike existing buildings in which members are assembled on site, the modular system is a system that completes a building by stacking and assembling prefabricated box-type units at the site vertically and horizontally.

This modular system not only secures uniform and excellent quality by pre-installing various interior and exterior materials and facilities as well as the frame, but also shortens the construction period by minimizing on-site processes.

In particular, since the plane of each household floor in an apartment building remains the same, construction is repeated for each floor by a large formwork such as a gang form. Unlike this, the roof top floor has a different planar shape from the lower units, so it is impossible to construct a large formwork, so it is mainly constructed with the RC method using conventional formwork.

However, it is difficult to secure uniform quality in such a conventional method. In addition, since the rooftop floor is constructed at the time of completion of the frame construction, there are difficulties in construction, such as restrictions on the supply of on-site manpower and the use of equipment such as tower cranes. Accordingly, the demand for modular systems is increasing.

The modular system can be said to be a key technology for the stability and constructability of the joining method between modular units.

Conventional Patent Registration No. 10-0923637 discloses a technique of fixing a modular unit with bolts and nuts by forming a cutout hole in a pillar.

However, the registration technique has poor workability because it inevitably loses the cross section of the member due to the cutting of the pillar, and requires putting a hand into the pillar to fasten the nut. In addition, only an open section member such as a C-beam can be used as a horizontal member to access the incision hole, but the open section member has a limited cross-sectional efficiency, so the size of the member must be increased and resistance to torsion is weak. In addition, since interior material assembly or fireproof construction is only possible after fastening the nut, there is a problem in that field work increases.

In addition, Patent Publication No. 10-2011-0053101 discloses a technique for fixing positions between modular units using guide pins. At this time, the guide pin is used only for fixing the position, and is coupled by a bolt to see.

In the case of the above technology, although no incision hole is formed in the column, since the upper and lower beams are joined with bolts, only open-section members can be used, resulting in reduced cross-sectional efficiency. And there is no choice but to assemble the interior materials afterward. In addition, since the beams, not the columns, are connected to each other, the columns are separated between the upper and lower units, so there is a limit to the transmission of the column axial force.

In order to solve the above problems, an object of the present invention is to provide a unit block system capable of easily coupling adjacent unit blocks and transmitting stress reliably.

The present invention is to provide a unit block system capable of improving workability by minimizing on-site processes.

The unit block system of the present invention is for interconnecting unit blocks 1 as shown in FIG.

The unit block 1 includes a plurality of lower horizontal members 2a, an upper horizontal member 2b, and a vertical member 3 connecting the upper and lower horizontal members 2a and 2b.

The unit block 1 may be provided with 4 lower horizontal members 2a, 4 upper horizontal members 2b and 4 vertical members 3, respectively, so as to have a rectangular parallelepiped shape.

Each corner of the unit block (1) is provided with a lower connector (4a) or an upper connector (4b) to interconnect the horizontal members (2a, 2b) and the vertical member (3).

Here, 'upper' and 'lower' are distinguished for convenience of explanation, and do not mean the upper and lower parts of the unit block 1. For example, the upper horizontal member (2b) and the upper connector (4b) may be located in the lower part of the unit block (1), the lower horizontal member (2a) and the lower connector (4a) is the upper part of the unit block (1) can be located in

The lower connector (4a) is provided at the lower edge of the unit block (1) to connect the lower end of the lower horizontal member (2a) and the vertical member (3).

That is, the lower connector 4a connects a pair of lower horizontal members 2a and vertical members 3 orthogonal to each other.

To this end, the lower connector 4a is configured to include a L-shaped connector body 40a.

Horizontal member junctions 41 are formed at both ends of the L-shaped connector body 40a so that the ends of the lower horizontal members 2a orthogonal to each other can be coupled to each other.

A vertical member joint 42 is formed on the upper surface of the connector body 40a so that the lower end of the vertical member 3 can be coupled.

The upper connector (4b) is provided at the upper edge of the unit block (1) and connects the top of a pair of upper horizontal members (2b) and vertical members (3) orthogonal to each other.

The upper connector 4b is also configured similarly to the lower connector 4a, and the horizontal member joint 41 is coupled to the ends of the upper horizontal member 2b orthogonal to each other at both ends of the L-shaped connector body 40b. is formed In addition, a vertical member joint 42 is formed on the lower surface of the connector body 40b so that the upper end of the vertical member 3 can be coupled.

Unit blocks (1) adjacent to each other are fixed to each other by guide pins (5) and fixing bolts (6).

To this end, a fixing groove 43 into which the upper end of the guide pin 5 is inserted and fixed is formed on the lower surface of the connector body 40a of the lower connector 4a.

The upper end of the guide pin 5 may be screwed into the fixing groove 43.

An insertion groove 44 into which the guide pin 5 can be inserted is formed on the upper surface of the connector body 40b of the upper connector 4b.

Accordingly, the upper unit block 1 is lowered while the upper end of the guide pin 5 is inserted into the fixing groove 43 provided in the lower connector 4a of the upper unit block 1. At this time, the upper end of the guide pin 5 is inserted into the fixing groove 43 and the lower end protrudes downward from the lower connector 4a.

While the upper unit block 1 is lowered, the lower end of the guide pin 5 is inserted into the insertion groove 44 formed on the upper surface of the upper connector 4b of the lower unit block 1'.

The guide pin 5 may be positioned on the same axis as the vertical member 3 to smoothly transfer stress between the vertical members 3 of the upper and lower unit blocks 1 and 1'.

The lower end of the guide pin 5 may be formed to be tapered so that the width becomes narrower toward the lower end so that it can be easily inserted into the insertion groove 44 .

At this time, a first fixing hole 45 communicating with the insertion groove 44 is formed on one side of the connector body 40b constituting the upper connector 4b of the lower unit block 1'.

In addition, a second fixing hole 51 is formed in the guide pin 5 to communicate with the first fixing hole 45 at a position corresponding to the first fixing hole 45 .

Therefore, after the guide pin 5 is inserted into the insertion groove 44, the fixing bolt 6 passes through the first fixing hole 45 of the upper connector 4b to fix the second fixing of the guide pin 5. By inserting into the ball 51, the upper and lower unit blocks 1, 1' are connected to each other.

The fixing bolt 6 prevents the guide pin 5 from vertically departing.

Unlike the conventional modular system in which the guide pin fixes only the plane position of the upper and lower unit blocks, in the present invention, the guide pin 5 not only fixes the plane position, but also connects the upper and lower unit blocks 1 and 1' to each other. It also serves as a link. Accordingly, the assembly time of the unit block 1 can be greatly reduced.

In addition, since the fixing bolt 6 is fastened within the upper connector 4b, it is not necessary to form the horizontal members 2a and 2b or the vertical member 3 into open sections. That is, for the horizontal members 2a and 2b and the vertical member 3, it is possible to use square tubes having excellent structural performance.

As shown in FIG. 3, a connecting plate 7 may be provided on top of the upper connector 4b adjacent in the horizontal direction to connect the unit blocks 1 adjacent in the horizontal direction.

A through hole 71 is formed in the connection plate 7 through which a guide pin 5 for connecting the upper and lower connectors 4a and 4b passes.

Figure 4 is a perspective view showing the coupling relationship of the upper and lower connectors, Figure 5 is a plan sectional view showing the upper connector, Figure 6 is a cross-sectional view along A-A 'of Figure 5 showing the order of coupling the upper and lower connectors.

When the fixing bolt 6 is fastened, the fixing bolt 6 may be fastened at the inner edge of the upper connector 4b so as not to interfere with the interior and exterior materials.

To this end, an accommodation space 46 is formed at the inner edge of the upper connector 4b so that the fixing bolt 6 can be accommodated, and an insertion groove 44 can be formed on the inner surface of the accommodation space 46. .

The stress of the upper horizontal member 2b coupled to the upper connector 4b is transferred by the upper and lower plates of the accommodation space 46.

Since there is almost no interference of the interior materials on the inside of the corner of the upper connector 4b, the entire interior and exterior materials can be pre-assembled at the factory. In addition, fireproof treatment can be pre-installed in most factories.

In addition, when the fixing bolt 6 is fastened, there is no interference of the horizontal members 2a and 2b or the vertical member 3, and there is no external work, so the work safety is excellent.

5 and 6, the inner circumferential surface of the insertion groove 44 communicates with the first fixing hole 45 and the second fixing hole 51 on the surface opposite to the first fixing hole 45. A third fixing hole 47 may be formed.

The opposite side of the first fixing hole 45, that is, the guide pin ( 5) It is possible to insert the end of the fixing bolt 6 by forming a third fixing hole 47 on the inner circumferential surface of the insertion groove 44 located on the rear side.

Accordingly, since the fixing bolt 6 is supported at two points of the first fixing hole 45 and the third fixing hole 47, it is firmly fixed.

As shown in FIGS. 4 and 5, the horizontal member joint 41 or the vertical member joint 42 has a member insertion groove having a shape corresponding to the end shape of the horizontal members 2a and 2b or the vertical member 3. (411, 421) is formed, the horizontal member (2a, 2b) or the vertical member (3) can be inserted into the member insertion groove (411, 421) and fixed.
