Description

Folding Support Complex {Folding Support Complex}

The present invention relates to a copper bar which is a temporary member for constructing a reinforced concrete structure.

For slab construction of reinforced concrete structures, the installation of slab formwork for concrete placement must be preceded, and the slab formwork must be supported by copper bars until rigidity is expressed by concrete curing. These clubs usually consist of a double tube structure for length adjustment according to the ceiling. However, the conventional copper barrier is difficult to install, dismantle and transport, causing air delays and increasing construction costs. The copper barrier, which has been buckled, cannot be recycled, which causes industrial waste.

It is an object of the present invention to simplify various installation and dismantling operations for causing air delay and increase in construction cost, and to provide various schemes for preventing buckling of the copper bars.

The biggest problem with using clubs was that they required a lot of repetition. In the past, the clubs were fixed on the floor and fixed and installed. Assemble horizontal barge to control buckling deformation and install slab formwork on it, pour slab concrete and cure it, harden slab concrete to a certain strength and then disassemble copper bar, horizontal bar and slab formwork to move to upper layer After multi-layered buildings were built by repeating the process of establishing and fixing a copper bar on the upper slab. However, in the conventional method as described above, it took a lot of time and effort to raise the horizontal bar to fix the horizontal bar, and to dismantle it again to move to the upper layer.

Therefore, in the present invention, the four pillars are installed to stand as one set, and when dismantled from the slab formwork and moved to the upper layer, the four pillars are retracted, and the work holes installed on one side of the building slab are directly connected to the working through holes. Provides a folding clubbed composite configured for transport (rising).

According to the present invention has the following effects.

1. It can reduce the air and labor required by repeating the installation, dismantling, transportation and re-installation of the group.

2. The transverse connection is made between the struts even if there is no separate cross assembly to prevent buckling of the group.

3. Foldable coupling structure between struts reduces transportation and storage costs by reducing the space required for transportation (rising) and loading.

The present invention is a copper composite complex consisting of four struts and the intermediate member interconnecting the four struts, the four struts, the first struts on each vertex located clockwise from one vertex of the virtual square on the floor surface; landlord; Second holding; Third holding; And fourth holding; The intermediate member may include: a first crossbar disposed to traverse the first and second supports horizontally so that both ends are hinged to the first and second supports, respectively; A second cross bar arranged to traverse the third and fourth supports horizontally so that both ends are hinged to the third and fourth supports, respectively; And one or a plurality of connecting rods arranged to horizontally cross the first crossbar and the second crossbar so that both ends are fixed to the first crossbar and the second crossbar, respectively. Provides a foldable composite complex configured to include.

Hereinafter, the present invention will be described in detail with the accompanying drawings.

As shown in FIG. 1, the present invention is configured such that the first to fourth pillars 110a, 110b, 110c, and 110d are installed to stand as one set. The four struts 110a, 110b, 110c, and 110d are interconnected by the intermediate member 120, whereby the four struts support the slab formwork together, thereby preventing buckling of the copper span.

As shown in FIG. 2, the intermediate member 120 includes a connecting rod 122 connecting the first cross bars 121a and the second cross bars 121b and the first and second cross bars 121a and 121b spaced in parallel to each other. It consists of. The connecting rod 122 may be configured in plural as necessary, and FIG. 2 illustrates an embodiment in which two connecting rods 122 are coupled between the first and second cross bars 121a and 121b.

Both ends of the first horizontal rod 121a are arranged to horizontally cross the first and second supports 110a and 110b, respectively, and are hinged to the first and second supports 110a and 110b, respectively. (See FIG. 3). Similarly, the second crossbar 121b is hinged to the third and fourth pillars 110c and 110d, respectively, in the state in which the second horizontal rod 121b is disposed to horizontally cross the third and fourth pillars 110c and 110d. To combine.

Hinge coupling is a coupling method in which the members can be rotated based on connection points between the members, and the first and second cross bars 121a and 121b and the first to fourth supports 110a, 110b, 110c, and 110d are all coupled. It is possible to rotate relative to the connection point. However, since the first and second rails 121a and 121b are coupled through the connecting rod 122, the first and second rails 121a and 121b behave together in the vertical direction.

The intermediate member 120 may be provided with a plurality of the four pillars (110a, 110b, 110c, 110d) at equal intervals, thereby strengthening the unity between the pillars, the greater the resistance to the buckling.

When supporting the slab formwork with the foldable composite composite 100, it is preferable that the occupied area of the four struts (110a, 110b, 110c, 110d) is 600mm × 600mm, in this case as shown in Figure 4a The strut (the first holding in the drawing) and the crossbar (the first cross in the drawing) are at right angles. The four pillars 110a, 110b, 110c, and 110d are respectively fixed at the bottom thereof to the bottom and at the top thereof to the slab formwork. Since the hinge coupling between the strut and the crosspiece is for up and down rotation, as shown in FIG. 4A, in the state where the foldable copper composite 100 supports the slab formwork, the intermediate member 120 connects the four struts and buckles. It only serves to fight against.

When dismantling the foldable composite complex 100, the upper and lower ends of the four struts are separated from the bottom surface and the slab formwork, and then the medial member 120 is rotated as shown in FIG. 4B.

4C illustrates a state in which the foldable clamshell composite 100 is completely folded, and the first and fourth pillars 110a and 4d, 110d, and the second and second pillars 110b and 110c are stacked.

The foldable composite complex 100 is preferably stored or transported in the state shown in Figure 4c, thereby minimizing the size of the working through-hole formed in the slab in advance for the operation of transporting the foldable composite complex 100 to the upper layer You can.

The four pillars (110a, 110b, 110c, 110d) may be configured to extend the length by the connecting pipe 130, respectively.

At this time, the connecting pipe 130, the upper and lower rotary disks (133a, 133b) coupled by the rotation center axis 135 in a state stacked on each other; An upper tube 131a having a lower end welded to an upper surface of the upper rotating disc 133a; And a lower tube 131b having an upper end welded to a lower surface of the lower rotating disc 133b. It can be configured to include. The upper and lower rotating disks 133a and 133b may be freely rotated about the rotation center axis 135 so that the upper and lower rotating disks 133a and 133b are welded to the upper and lower rotating disks 131a and 133b, respectively. The 131b may be coupled to or disassembled from the struts 110a, 110b, 110c, and 110d while rotating in opposite directions.
