Description

BEAM HOLLOW PIPE AND MANUFACTURING METHOD THEREOF

The present invention relates to a hollow tube for a dam, and more specifically, to a hollow tube for a dam that is installed inside the dam and provides a hollow space for installing a cable or the like inside, and a method for manufacturing the same.

In various buildings such as factories or large buildings, various cables such as communication or power cables, telephone lines, or public lines are installed to supply power, connect communication lines, or supply fluids.

Typically, the above cables are laid underneath the ceiling slab using cable trays, cable ducts, conduits, etc.

The above cable tray has the function of making the appearance of various cables installed more attractive, relieving inconvenience to passersby, and preventing various cables from becoming tangled.

For example, patent documents 1 and 2 below disclose cable tray and cable duct configurations applicable to buildings.

Meanwhile, in places where aesthetics are not greatly considered, such as underground parking lots or warehouses, it is sometimes installed inside hollow pipes installed between beams without cable trays or channels.

For example, Fig. 1 is a drawing illustrating a state in which a hollow tube is installed according to conventional technology.

A hollow tube (1) according to the prior art is installed in a state exposed to the lower part of a ceiling slab (2), as shown in Fig. 1.

These hollow tubes (1) are placed between beams (3) that are partially installed on the ceiling slab (2) and are fixed by the beams (3).

In this way, when installing a hollow pipe (1) without a cable tray or duct, interference must be avoided during the transport of vehicles or goods.

Due to this, the maximum number of floors that can be secured during construction of a building may be adversely affected as the floor height increases by the height required to install the hollow pipe (1).

In addition, since the hollow pipe (1) must be placed based on the beam (3) constructed in the building, there was a problem that the installation location of the hollow pipe (1) was limited and the difficulty level increased during design work.

Hereinafter, terms indicating directions such as 'left', 'right', 'front', 'rear', 'upper', and 'lower' are defined as indicating each direction based on the state depicted in each drawing.

A hollow tube (10) according to a preferred embodiment of the present invention includes a main body (20) that is installed inside the tube and has a hollow space formed therein through which a cable is routed, as shown in FIGS. 2 to 4, and one or more pairs of first reinforcing bars (30) that are arranged on both sides of the main body (20) to provide rigidity and support to the main body (20).

And according to a preferred embodiment of the present invention, the hollow tube (10) includes one or more pairs of second reinforcing bars (40) installed on the upper and lower sides of the main body (20) to provide rigidity and support to the main body (20), and the first and second reinforcing bars (30, 40) can be connected to main reinforcing bars (not shown in the drawing) installed inside the beam and in the ceiling slab.

The main body (20) can be formed in a shape and size corresponding to the installation space formed inside the vessel so that it can be installed inside the vessel.

For example, the main body (20) may be provided as a solid body having a square cross-section, as shown in FIG. 2.

Of course, the present invention is not necessarily limited to this, and the main body (20) may be changed to a cylinder with a circular cross-section or a polygonal shape such as a triangle or hexagon.

A flange having a through hole may be provided on the outer surface of the main body (20) so that first and second reinforcing bars (30, 40) can be installed.

For example, a pair of first flanges (21) may be provided on each side of the main body (20), through which one or more pairs of first reinforcing bars (30) are connected through penetration.

And, a pair of second flanges (22) may be provided on the upper and lower surfaces of the main body (20), respectively, through which one or more pairs of second reinforcing bars (40) are connected through penetration.

Through holes (23) through which first and second reinforcing bars (30, 40) are connected through can be formed in the first and second flanges (21, 22), respectively.

Here, in FIGS. 2 to 4, five through holes (23) are illustrated so that five pairs of first and second reinforcing bars (30, 40) are connected to each flange (21, 22), but the present invention is not necessarily limited thereto, and the number and spacing of the through holes (23) formed in each flange (21, 22) and the number of the first and second reinforcing bars (30, 40) may be variously changed depending on the length of the main body (20), the size of the load applied to the hollow tube (10), etc.

The main body (20) can be formed by bending a metal plate having rigidity and corrosion resistance, such as steel, stainless steel, or aluminum.

For example, the main body (20) can be manufactured by folding approximately 90° along four first folding lines (24) displayed at preset positions so as to have the left-right width and the up-down height of the main body (20) to be manufactured as a square-shaped plate, as shown in FIG. 3, and joining the two ends of the plates that are in contact with each other by welding or the like.

Here, as a pair of first and second flanges (21, 22) are formed in the central portion of each outer surface of the main body (20), three second folding lines (25) can be formed between each first folding line (24) to form each flange (21, 22).

Among the three second folding lines (25), the two second folding lines (25) arranged on both sides are formed to be bent approximately 90° toward the outside and inside with respect to the main body (20), and the second folding line (25) in the center can be formed to be bent approximately 360°.

The first reinforcing bar (30) can be arranged vertically along the up-down direction on both sides of the main body (20), and the second reinforcing bar (40) can be arranged horizontally along the width direction of the main body (20) on both sides of the main body (20).

The first and second reinforcing bars (30, 40) are each provided with a length longer than the width in the left-right direction and the height in the up-down direction of the main body (20), and can be installed on the outside of the main body (20) to form an approximately square frame shape.

The first and second reinforcing bars (30, 40) formed in a square frame shape like this are firmly connected to each other using a fixing member such as a wire, or a connecting means such as a clamp or coupler, and can provide a supporting force for supporting the hollow tube (10) and the beam.

Of course, the first and second reinforcing bars (30, 40) can be firmly joined to each other at the contact points by welding or the like.

Therefore, the first and second reinforcing bars (30, 40) extend outward from the upper and lower ends and both ends of the main body (20) and can be connected to the main reinforcing bars installed inside the beam and in the ceiling slab.

Meanwhile, in this embodiment, it has been described that one or more pairs of first and second reinforcing bars (30, 40) are arranged vertically and horizontally on both sides and upper and lower sides of the main body (20), but the present invention is not necessarily limited to this.

For example, the present invention may be modified to place a main body (20) having a square cross-section rotated to one side by about 45° to form a diamond shape, or to place one or more pairs of first and second reinforcing bars (30, 40) on the outside of a main body (20) having a polygonal or cylindrical cross-section so as to have an incline corresponding to the outer surface of the main body (20).

Additionally, the present invention may be modified to additionally install a plurality of third reinforcing bars along the longitudinal direction of the main body on both sides and the upper and lower sides of the main body.

For example, FIG. 5 is a perspective view of a hollow tube according to another embodiment of the present invention.

A hollow tube (10) according to another embodiment of the present invention has the same configuration as the hollow tube described with reference to FIG. 2, except that, as shown in FIG. 4, a pair of connecting flanges (26) may be formed by bending toward the outside of the main body (20) at each of the front and rear ends of the main body (20). In addition, a plurality of through holes (23) may be formed in the pair of connecting flanges (26), through which a plurality of third reinforcing bars (50) installed horizontally along the longitudinal direction of the main body (20), i.e., the front-back direction, penetrate and are connected.

In this way, the present invention can further improve the longitudinal rigidity and support capacity of the main body by providing connecting flanges at the front and rear ends of the main body and additionally installing a third reinforcing bar along the longitudinal direction of the main body.

Meanwhile, the main body (20) may be formed with a length corresponding to the length of the beam, or, if the length of the beam is long, may be formed by connecting a plurality of main bodies (20) to correspond to the length of the beam.

Here, when the third reinforcing bar (50) is applied as shown in Fig. 5, the main bodies (20) that are connected to each other can be tightly connected using the third reinforcing bar (50).

Of course, if the third reinforcing bar is not applied, the main bodies can be tightly connected to each other using connecting members such as bolts and nuts.

Next, a method for manufacturing a hollow tube according to a preferred embodiment of the present invention will be described in detail with reference to FIG. 6.

Figure 6 is a process diagram explaining step-by-step a method for manufacturing a hollow tube according to a preferred embodiment of the present invention.

In step S10 of Fig. 6, a metal plate is folded along each of the first and second folding lines (24, 25) at preset positions to form a main body (20).

Then, the main body (20) is formed into a cylindrical shape with a rectangular cross-section, and a first flange (21) and a second flange (22) are formed on both sides and the upper and lower surfaces of the main body (20), respectively. Here, one or more through holes (23) may be formed in the first and second flanges (21, 22) by a perforation method.

Of course, if necessary, additional connecting flanges (26) may be formed at the front and rear ends of the main body (20).

In step S12, one or more pairs of first reinforcing bars (30) are connected to each side of the main body (20). Each first reinforcing bar (30) is vertically arranged on both sides of the main body (20) by being connected through a through hole (23) formed in each first flange (21), and protrudes upward and downward from the upper and lower ends of the main body (20).

In step S14, one or more pairs of second reinforcing bars (40) are connected to the upper and lower sides of the main body (20). Each second reinforcing bar (40) is connected through a through hole (23) formed in each second flange (21), and is horizontally arranged on the upper and lower sides of the main body (20), and protrudes outward from both ends of the main body (20), that is, to the left and right.

In this way, the first and second reinforcing bars (30, 40) arranged on the outside of the main body (20) are connected to each other to form a square frame shape, and the portions where the first and second reinforcing bars (30, 40) come into contact with each other are connected or joined.

Through this process, the assembled hollow tube (10) is placed at the location where the beam is to be constructed on the ceiling slab of the building, and concrete is poured to construct the beam (S16). At this time, the first and second reinforcing bars (30, 40) are tied to the main reinforcing bars installed inside the beam and on the ceiling slab.

Afterwards, various cables such as communication or power cables, telephone lines, or public lines are installed in the hollow space formed inside the borehole tube (10).

Accordingly, the hollow tube (10) shields the outside of the cables installed inside and safely protects them.

Through the process described above, the present invention can provide a hollow space installed inside a hull into which cables, etc. can be installed.

In addition, the present invention can improve the supporting capacity by connecting the reinforcing bars installed around the main body to the main reinforcing bars installed in the beam and ceiling slab, and safely protect the cables installed inside.

In addition, the present invention has a simple structure, is easy to manufacture, and can be modified according to the installation environment.

Accordingly, when the present invention is applied to buildings such as underground parking lots or logistics centers, the space for installing cables can be minimized by arranging hollow tubes inside beams designed with passageways in mind, thereby reducing the floor height of the building and increasing the maximum number of floors that can be constructed.

Although the invention made by the present inventor has been specifically described according to the above embodiments, the present invention is not limited to the above embodiments, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.

The present invention applies to a hollow tube installed inside a dam and providing a hollow space in which cables, etc. can be installed, and a technology for manufacturing the same.
