Description

Folding joint structure of Support components and Folding multi-support}

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.

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, four pillars are bundled and installed to stand as one set, and when dismantled from the slab formwork and moved to the upper layer, four pillars are closed to work through holes installed on one side of the building slab. Provides multiple folding clubs configured for immediate transport (rising).

In addition, the present invention provides a folding coupling structure between the members of the copper bar configured to fold the acupressure plate coupled to the top, bottom of the copper bar strut.

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. Even if there is no separate assembly, the buckling of the club is prevented because the lateral connection is made between the clubs.

3. Foldable coupling structure between copper bar members (chiropractor, strut) can be applied to the coupling structure of articulated copper bar which is mounted on reverse casting slab formwork.

4. It can reduce the space required for transporting (lifting) and loading by folding folding structure between members.

I. Dongbari Absence Folding mating structure.

The present invention is a coupling structure between the tubular support (1) and the acupressure plate (2), vertically coupled to the plate surface of the acupressure plate (2) fitting fitting tube (3) fitted to the inside or outside of the support (1); Long hole groove (4) formed vertically on both sides of the support (1); And c-shaped round bar (5), both ends of which are fused to the pressure plate (2) in the state inserted into the long hole groove (4); Consisting of, the support (1) and the pressure plate (2) is coupled through the fitting tube 3 and the c-shaped round bar (5), and in the state that the support (1) and the fitting fixing tube (3) is separated The acupressure plate (2) provides a folding coupling structure between the members of the copper bar, characterized in that configured to rotate left and right about the c-shaped round bar (5). The long hole groove 4 may be padded with a washer 6 to be fastened to the c-shaped round bar 5 together.

As will be described later, the folding member between the copper barrier members can be usefully used as a coupling structure for coupling the pressure plate to the upper and lower portions of the copper barrier. When supporting the slab formwork with a copper bar provided with a folding coupling structure as described above, the support (1) is not separated from the state fitted to the fitting tube (3) by the compressive force acting at the top. On the other hand, during the dismantling operation of the club, the length of the club can be reduced (due to the length control by the double tube structure), and then the support (1) and the fitting tube (3) can be dismantled and rotated by rotating the pressure plate (2). See Figure 1)

On the other hand, the present invention, as shown in Figure 2 on the pressure plate 2, the plate 7; It is further provided, the fitting tube 3 and the c-shaped round bar (5) is fused to the plate 7, the rivet (8) fixed to penetrate the center of the plate 7 and the pressure plate (2) ; It is configured to include, the pressure plate 2 provides a foldable coupling structure between the members of the copper bar, characterized in that configured to rotate the rivet (8) axially. By this configuration, the pressure plate 2 can be folded up and to the left and, of course, rotated about the central axis. At this time, the axial rotation of the pressure plate (2) is a relative concept, if the pressure plate (2) is rotated on the basis of the state that the plate 7 is fixed, if the pressure plate (2) is fixed The face plate 7 is axially rotated.

Such a "foldable coupling structure between member members" can be applied to the coupling structure of the articulated copper bar mounted on the lower portion of the reverse casting form to construct a building by a top-down method as shown in FIG. The articulation club refers to a group of clubs that can be folded and unfolded, mounted on the bottom of the inverse casting form, such as a leg of a sitting desk or a table. Regardless of how the posts are constructed, the articulation club is fixed to the pressure plate (2) in the lower portion of the reverse casting form, and the support posts (3) and the c-shaped round bar (5) having the configuration as described above. By connecting (1) and the pressure plate (2), it is configured to be able to fold to the bottom of the reverse pouring formwork or to stand fixed to the bottom. Of course, in this case, as shown in FIG. 2, if the pressure plate 2 is configured to be axially rotated and the pressure plate 2 is fixed to the lower portion of the inverse casting form, the refraction that behaves together with the cover plate 7. The club can be rotated freely and folded up to the desired position.

II. Foldable multi Dongbari

The present invention is an individual length adjustable four double tube support (11); A folding body (12) which connects the four double pipe supports (11) to the X letter and rotates around the intersection points; And acupressure plates 2 respectively coupled to upper and lower ends of the double pipe support 11. Provides a foldable multiple clubs 10, characterized in that configured to include.

The four double tube support 11 is to be applied to the general variable-length copper club, in the present invention, the four double pipe support 11 is configured to be connected and freely folded and unfolded by the folding coupling body 12 is arranged cross-X There is a characteristic in point.

The folding assembly 12 is to be fastened to the intersection by the pin, so that the intersection can be the center point of the folding assembly rotational movement, as a result, the folding assembly is rotated like scissors, and the four double pipe support 11 is retracted (See FIG. 4) Of course, the folding member 12 may be provided with a fixing member for fixing in a state in which the folding assembly 12 is unfolded or overlapped with an II letter.

Looking at the function of the folding multiple clubs 10 in detail. When supporting the slab formwork with the foldable multi-panel 10 to expand the four double pipe strut 11 so that the occupied area is 600mm × 600mm. When transporting the foldable multi-ply club (10) to the upper floor, the operator moves (elevates) through the working through-hole formed in 300mm × 1000mm in advance in the construction slab by retracting the four double pipe support (11) to 800mm × 200mm Make it easy to reinstall.

However, when transporting the multi-fold folding club 10 in the above manner to the upper layer, the pressure plate (2) coupled to the upper and lower ends of the double pipe support (11) may be a problem. The pressure plate (2) coupled to the bottom of the double pipe support (11) is a member necessary for self-reliance of the copper bar, and the pressure plate (2) coupled to the top of the double pipe support (11) serves to primarily support the load of the slab formwork. In order to perform the above role, the pressure plate (2) is composed of a wide plate (for example, 180mm × 180mm), so that even when the four double pipe support (11) is retracted during the movement of the multi-fold folding club (10) This is because the acupressure plate 2 can be caught in the working through hole.

Nevertheless, it is difficult to prevent the fall of the worker and the slab structure to make the work through hole infinitely large. Therefore, the acupressure plate (2) also needs to be minimized to facilitate the use of the through-hole by configuring a folding 90 °. To this end, it is preferable to apply the above-described "folding structure between the members between the members." According to this, when holding the slab formwork with the foldable multi-ply club 10, the double pipe support 11 is left in a state of fitting with the fitting tube 3 coupled to the pressure plate 2, the foldable multi-pound club 10 When moving to the upper layer can be used to fold the pressure plate (2) after the separation of the double pipe support (11) and the fitting tube (3).

The foldable multi-ply club 10 is to adjust the length of each of the double pipe support (11), to control the expansion or contraction of four double pipe support (11) by the folding coupling 12, the double pipe by the folding coupling structure between the members The support 11 is fixed on the acupressure plate 2 or fixed to raise the acupressure plate 2 to be freely realized so that it can be flexibly applied to various situations in construction. This folding multiple clubs 10 can be applied to the slab construction process as shown in FIG.

Meanwhile, the present invention cross-connects four end pipes 13 and the four end pipes 13 fixed in a predetermined position by moving up and down in a state of being fitted to the upper or lower portions of the four double pipe props 11. A movable folding assembly (15) consisting of a connecting portion (14) which rotates about an intersection point; Provides with a folding multiple club (10), characterized in that further comprises a.

The movable folding assembly 15 performs the same function as the above-mentioned folding assembly 12, but the above-mentioned movable folding assembly 15 is required to be applied to a copper bar strut having a length-adjustable double tube structure. That is, the movable folding assembly 15 is a component for fixed use by moving to the most desirable position in the structure in response to the change in the length of the double pipe support (11).

In addition, the movable folding assembly 15 may be used that the connecting portion 14 is reinforced with the inclined member (16). If the connecting portion 14 is referred to as a 'beam', the inclined member 16 is a 'beam support member', and the inclined member 16 prevents bending or twisting of the connecting portion 14.
