Field of the Invention The present invention relates to a construction method for constructing a support structure for dispersing a load applied to a lower portion of a tower crane, RC) to construct a tower crane RC lower support structure which can easily install a tower crane and distribute loads to support high strength.
In general, tower cranes are used as a means to lift and move workpieces from a construction site, such as a building, to a required location, and are used to construct high-rise buildings.
These tower cranes are generally installed higher than the number of buildings, and as the number of floors increases, the weight of the tower crane also increases as the height of the tower crane is increased. .
FIG. 1 is a plan view of a conventional tower crane foundation, in which the upper end of the base portion is flattened so that the weight of the tower crane also increases with the increase of the support frame to come into contact with the lower end of the tower crane The floor or slab receives the load of the tower crane intensively, so that the durability of the surface contacting the tower crane decreases with the accumulation of fatigue, and the stability of the ground is also lowered.
Further, the conventional tower crane has a problem that the strength of the supporting portion of the ground is weakened by installing the lower frame of the power crane on the ground.
The present invention has been devised in order to solve the above-described problems, and more particularly, it is an object of the present invention to improve the stability with the ground by dispersing the load generated at the lower end of the tower crane, And an object of the present invention is to provide a tower crane RC lower support structure and a construction method for facilitating installation and maintenance.
In order to achieve the above object, the present invention provides a method of constructing an RC lower support structure for dispersing a weight applied to a support portion of a tower crane T installed for high-rise building construction and improving stability with the support portion (A) a step of forming a predetermined depth on a ground surface of a construction site where the tower crane (T) is installed, and (b) a step of forming a plurality of (C) a step in which reinforcing rods are formed and laid so that the embedded pile columns C are laid vertically and the

According to another preferred embodiment of the present invention, the elastic frame (F) is arranged in parallel and forms an interval between the upper frame and the lower frame, and is formed in a zigzag fashion between the upper frame and the lower frame And an elastic portion to which the elastic member is attached.
On the other hand, the description of the technology disclosed herein is merely an example for structural or functional explanation, and the scope of the right of the disclosed technology should not be construed as being limited by the embodiments described in the text. That is, the embodiments are to be construed as being variously embodied and having various forms, so that the scope of the disclosed technology should be understood to include equivalents capable of realizing technical ideas. Also, the purpose or effect of the disclosed technology should not be construed as being limited thereby, as it does not mean that a particular embodiment must include all such effects or merely include such effects.
Also, the meaning of the terms described in the present invention should be understood as follows. The terms "first "," second ", and the like are intended to distinguish one element from another, and the scope of the right should not be limited by these terms. For example, the first component may be referred to as a second component, and similarly, the second component may be referred to as a first component.
Further, when an element is referred to as being "connected" to another element, it should be understood that other elements may also be present in the middle, although it may be directly connected to the other element. On the other hand, when an element is referred to as being "directly connected" to another element, it should be understood that there are no other elements in between. On the other hand, other expressions describing the relationship between components, such as "between", "between" or "neighboring to" and "directly adjacent to" should be interpreted as well.
It should be understood that the singular " include "or" have "are to be construed as including a stated feature, number, step, operation, component, It is to be understood that the combination is intended to specify that it does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.
According to the present invention, the lower crane supporting structure and the construction method of the tower crane disperse the load applied to the supporting portion of the crane and facilitate the installation and maintenance, thereby improving the stability of the ground contacting the crane, The lifetime can be increased and the safety can be maintained.
