Description

High Strength Concrete Float {FLOATING BODY FOR HIGH STRENGTH CONCRETE}

The present invention relates to a high-strength concrete floating body, and more particularly to a high-strength concrete floating body used in the waterborne structure.

Recently, the use of floating structures by installing floating bodies in the sea, rivers, lakes, etc. is increasing.

Such floating water structures are typically used as offshore plants, water fishing grounds, and water parks, and their size is also gradually increasing.

The floating body is generally made of concrete, and is a hollow rectangular structure, and for the structural efficiency of the floating body, bulkheads are usually installed at regular intervals in an internal space to form a plurality of hollow portions, or It can also be filled with buoyancy material in the interior space.

The concrete floating body as described above, the concrete is poured into the formwork in a factory to produce a floating body, wherein the concrete is mixed with various additives such as aggregate.

However, the concrete floating body is not only difficult to uniformly mix various additives such as aggregates in the formwork when the concrete is poured into the entire floating area, and also cannot precisely match the density or weight of each part of the concrete floating body. There is a problem that the buoyancy of each part of the concrete floating body is uneven.

In addition, when the above-mentioned concrete floating body is installed in the water phase, since the buoyancy is not uniform, the concrete floating body is tilted to either side, and even if a plurality of such concrete floating bodies are connected, the tilting of each concrete floating body is caused. Since the direction is different from each other, it is difficult to level the entire floating body as well as structural instability, as well as a lot of load acting on the connection structure, there was a lot of problems in the stability of the water structure.

In addition, when connecting a plurality of concrete floating body, in order to prevent breakage during the collision between each concrete floating body is provided with a buffer space of a predetermined gap between the concrete floating body, the buffer space between each concrete floating body due to the There was also a problem that a safety accident occurs, such as a person trips over the fluid can trip over or fall.

An object of the present invention for solving the above problems is to form at least four buoyancy control pockets on the floating body formed of high-strength concrete and a plurality of weight blocks in the four buoyancy control pockets in accordance with the slope of the floating body By selectively inserting and connecting the plurality of floats in a buffered manner through the connecting device, the buoyancy of the plurality of floats is adjusted to be uniform (leveling) to prevent the tilting of the float and thereby the entire float It is possible to maintain the level of the uniformity of the structure to improve the stability, and also to fill the buffer space between each floating body inevitably generated by the connecting device through the filling means to eliminate the gap between each floating body High-strength concrete floating to prevent safety accidents when a person walks on the floating body To provide for.

The present invention for achieving the above object is arranged adjacent to each other in the longitudinal direction or the width direction, and each buoyant buoyancy space is formed to provide a buoyancy, the outer wall is formed of a high-strength concrete material Floating body, buoyancy material to be filled in the buoyancy space portion to increase the buoyancy of the floating body, and a predetermined depth is formed on the upper side of the floating body in the lower direction, constant in the longitudinal direction and the width direction of the floating body At least four buoyancy control pockets spaced apart from each other, and a plurality of selectively installed in the interior of the at least four buoyancy control pockets according to the inclination of the floating body to adjust the buoyancy of each part of the floating body evenly A weight block and a connecting device for connecting the plurality of the separated floating bodies to be buffered with each other; By the devices connected to each other to be spaced a predetermined interval to fill the expansion space between each of the float it characterized in that the filling consisting including means disposed in the expansion space.

The present invention, at least four buoyancy control pockets are formed on the floating body formed of high-strength concrete, and in the four buoyancy control pockets, a plurality of weight blocks are selectively inserted and installed according to the inclination of the floating body and the connection device is provided. By connecting the plurality of floats bufferably through the buoyancy, by adjusting the buoyancy of the plurality of floats to be uniform (leveling) to prevent the tilting of the float and thereby to maintain the horizontal level of the entire float uniformly The stability of is improved.

And, by filling the buffer space between each floating body inevitably generated by the connecting device through the filling means, the gap between each floating body is eliminated, so that people fall on the floating body when falling or fall Safety accidents such as falling out can be prevented.

In addition, since the filling means is formed of a resilient rubber material, even if the buffer space is filled, it is possible to prevent the breakage of the floating body by maintaining the buffer function between each floating body as it is.

In addition, by connecting a plurality of floats into one through a connecting device composed of a buffer member and a wire connector, it is possible to easily and quickly connect the plurality of floats, thereby shortening the construction time of the floating structure.

In addition, because of the use of high-strength concrete material, even if used as an aquatic structure, it can improve the durability and prevent the crack of concrete due to the change of water temperature, and also prevent corrosion by sea water when installed at sea. Even if the buoyancy control pocket and the weight block can be easily adjusted through it can further improve the stability of the water structure.
