Description

Concrete structure

The present invention relates to a concrete structure, and more particularly to a concrete structure with improved reinforcing members embedded therein for structural reinforcement of concrete.

In general, the basic frame of a building, bridge, retaining wall, port construction, etc. is made of reinforced concrete. The reinforced concrete is fixed to the vertical and horizontal arrangement of the reinforcing bar after forming the frame of the frame using the formwork to form the basic frame in the state of completion of the basic construction. In this case, in the case of the vertical frame, the frame of the vertical frame is defined using a straw after fixing the reinforcing bar. In this state, the concrete is poured into the space defined by the straw.

In the concrete structure manufactured as described above, in installing the reinforcing bars, the reinforcing bars are connected by using wires or joints. In the construction of the beam in this process, there is a problem in that it takes a relatively large amount of rebars because the reinforcing bars must be folded to a set length. In addition, the supply and demand of the rebar is unstable depending on the construction market.

Registered utility model 20-0323938 discloses an example of a reinforcing bar arrangement structure, and registered utility model 20-0321183 discloses a reinforcing bar connection device.

The reinforcing bar arrangement structure includes a bush surrounding a separate reinforcing bar to be firmly fixed to orthogonal portions of the reinforcing bars, and a fastening member for fastening by fastening the vertical bar to the fastening unit. The reinforcing bar coupling device includes a coupler for supporting both ends of the reinforcing bar and a coupler coupler screwed with the joint coupler to tighten the reinforcing bars supported by the joint coupler.

The arrangement of the reinforcing bar and the joint device can reduce the rebar due to the rebar butt joint, but the structure of the joint device is complicated and not easy to work, so it is difficult to reduce the cost and improve the productivity.

As described above, when constructing a frame of a building using reinforcing bars, a lot of restrictions are placed on the height of a single construction. In other words, when installing rebars vertically and horizontally, the construction is difficult because they are bent or sag due to their own weight, and the relative structural strength of the reinforcing bar alone is weak, so that many pillars are required to support the reinforcing bars and the straw. In addition, in the case of the reinforcing bar is embedded in the concrete and is integrated with the concrete to reinforce the compressive force and shear force acting on the frame, but it is not easy to absorb the vibration applied from the outside.

On the other hand, in recent years, since sand, which is the main material of concrete, is sea sand collected from the sea, it contains salt, and the reinforcing bars embedded in the concrete easily corrode, and the volume of the reinforcing bars expands due to corrosion, which causes cracks in concrete. .

The present invention is to solve the problems as described above, it is an object of the present invention to provide a concrete structure that is easy to construct a reinforcing member embedded in concrete to supplement the structural strength, and can reduce the production cost per unit volume.

Another object of the present invention is to provide a concrete structure that can absorb shock, increase durability, and easy construction.

Another object of the present invention is to provide a concrete structure capable of preventing cracks in concrete due to expansion of different volumes due to corrosion of the reinforcing member embedded in the concrete.

And in forming the concrete frame 30, it is necessary to connect the reinforcing bars 42 or pipes 43 immersed in the relatively long length, in which case the pipes 43 are connected by connecting means . 6 and 7 show an embodiment of the connecting means 60.

The connecting means 60 is inserted into both sides of the pipes 43 and 43 'to be connected, respectively, and as shown in FIGS. 9 and 10, the rod-shaped parts having pipe inserts 62 and 63 on both sides. It consists of a connecting member 61, the locking jaw 64 is formed at the center of the connecting member 61 to limit the length of the insertion portion 61, 62 is inserted into the pipe 43, 43 ' Done.

The connecting means is not limited to the above-described embodiment and may be any structure as long as it can connect pipes.

Referring to the action of the concrete structure according to the present invention configured as described above are as follows.

In order to construct the concrete frame 30 of the concrete structure 30 according to the present invention, the structure is assembled in the shape of the frame using the reinforcing member 42 or the pipe 43 which is the reinforcing member in the state in which the basic construction is completed. In this case, when the pipe 43 is thin and difficult to be supported by its own load, the pipe 43 may be assembled in a supported state by using straw. Here, the height of the structure should be made in a range that can maintain the structural strength of the pipe (43). The pipes 43 should have an interconnected structure. The pipes 43 are connected to each other by inserting portions 62 and 63 of the connecting member 61 between the corresponding pipes 43 and 43 '. By fitting to pipes 43 and 43 '. As described above, since the ratchet 65 is formed on the outer circumferential surface of the insertion portions 62 and 63 inserted into the pipes 43 and 43 ', it can be prevented from being separated from the pipes 43 and 43'.

And when forming a column or beam, as shown in FIG. 13, the wave reinforcing members 40 should be supported by separate spacing members 70 to maintain the spacing. In the process of making a frame shape using the pipe 43, which is the reinforcing member 40, the fixing between the pipes 43 is not shown in the drawing, but is fixed or contacted using a separate spacing member 70 wire. The pipes 43 can be fixed to each other using wires or clips. The gap maintaining member for maintaining the gap of the pipes 43 may be made of rebar. In the process of installing the gap maintaining member, the coupling assisting means is installed at regular intervals along the pipe, thereby simplifying work by installing on the basis of this.

When manufacturing of the structure by the pipe is completed as described above, install the straw to partition the outer peripheral surface of the structure. During installation of the straw, the straw may be partially suspended by a pipe.

Since the structure of the structure manufactured as described above is provided with a pipe 43 having a hollow portion 41 as a reinforcing member inside the concrete, it is possible to increase the bearing capacity for a load acting perpendicular to the frame or beam. That is, since the concrete reinforcing member is made of a pipe, the structural strength can be increased by a pipe having a relatively high cross-sectional coefficient compared to that of the reinforcing bar. In particular, since both sides of the pipe 43 are sealed by the cap 44 and embedded in the interior of the concrete, the exposure of the inner circumferential surface of the pipe is blocked at the source to prevent corrosion, and the hollow part of the pipe is applied from the outside. Not only does the shock absorbing shock absorb, but also the inside of the pipe embedded in the interior of the concrete to maintain a sealed state can absorb vibration and noise.

In addition, since the coupling auxiliary means 50 is installed on the outer circumferential surface of the pipe 40 at predetermined intervals, it is possible to prevent the separation of the pipe from the concrete by increasing the coupling force of the concrete and the pipe to be integrated with the concrete.

On the other hand, since the hollow portion 41 is formed in the reinforcing member 40 or the pipe 43 which is the reinforcing member 40, the hollow portion 41 is corroded due to the concrete 20 containing salt, so that the volume thereof is expanded. As a result, the expansion force can be absorbed to prevent cracking in the concrete.

As described above, the concrete structure according to the present invention has a hollow portion formed in the longitudinal direction in the reinforcing member installed in the concrete, thereby significantly reducing the noise generated by the support strength and the vibration and the impact. Since it is relatively inexpensive and can reduce its own weight, it has the advantage of greatly reducing the production cost.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.

Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
