Description

Plate-shaped composite structure for punching crack reinforcement of column lower foundation {Reinforcement}
The present invention is to support the lower end to be supported by the ground floor to support the object with a large load, such as buildings or steel structures, such as buildings, apartments, steel towers, lower bridges, more specifically, deeply dug downwards to the bottom Instead of forming a thick concrete layer to form a foundation structure, a plate type for reinforcing punching cracks at the base of a column under the column that is small in volume and simple, and can prevent the punching crack under the column under high load while reducing the depth of pit. For composite structures.
In general, in order to prevent the ground from sinking due to the weight of buildings, bridges, tower cranes, etc., the foundation structure is constructed in the lower part of the building so that the building load is evenly transmitted and supported on the ground. Mainly used thick reinforced concrete structure. As the building heightened and the size increased, the load applied to the foundation structure per unit area also increased. For the foundation structure used, the strength was increased by increasing the thickness of the foundation structure made of the reinforced concrete structure.
Therefore, as the size or thickness of the foundation structure increases, the depth of burrow to form the foundation structure, that is, the depth of the trench is deepened. This caused the problem of increasing the construction period and excessive cost of construction for the excavation due to the complexity of the ground excavation work and the foundation structure installation process to form the foundation structure. In particular, when there is a rock-type ground in the lower part of the building, there is a problem that takes a longer construction period and construction cost to deepen the trench.
In addition, if the trench is deepened, it is necessary to prevent the collapsed basement wall from collapsing and to incline the slope to widen the upper side in order to secure a working space, thereby causing damage to adjacent buildings or making construction difficult in crowded places. have. In addition, if the upper side is inclined to be inclined to be wider, the space to be poured is increased, so there is a disadvantage that wastes concrete.
1A and 1B are diagrams for explaining the punching pressure concentrated in the cross section of a general foundation bottom. Referring to FIG. 1A, a punching pressure is formed and applied in an oblique direction C of about 45 degrees between a vertical column A and a horizontal base bottom B. FIG.
However, when there is no configuration that can support such a punching pressure in the foundation floor (B), a punching crack is generated by the punching pressure, resulting in deformation or breakage of the building structure.
This also applies to FIG. 1B of the method of using anchors (a) to prevent injuries of buildings. Since the anchor (a) serves to pull the building downward, the direction of the punching pressure may appear in a downward direction such as C 'or a hole may be formed only in the anchor portion.
In order to prevent this, multiple reinforcing structures are formed in the foundation floor, and this reinforcing method has a problem in that the installation process itself requires a lot of time, as well as having multiple layers. In addition, the thickness of the foundation floor has to be thick, so the consumption of concrete is considerably increased and the construction cost is increased, and the punching crack must be solved by the reinforcement method of steel, so it has a relatively low load bearing capacity.
The present invention is to reduce the depth of the trench to the bottom of the bottom concrete layer, or to provide a relatively simple structure inside the bottom concrete layer, without the process of digging, the plate-shaped punching crack reinforcement of the base of the lower pillar that can solve the above problems It is an object to provide a composite structure.
In addition, when forming a foundation in the ground such as a pillar foundation of a building, a bridge foundation, a bottom foundation of a tower crane, and a bearing wall, the overall load is weighted downward to prevent the punching crack occurring in the pillar foundation. It is an object of the present invention to provide a plate-like composite structure for punching crack reinforcement of a lower pillar base, which is capable of efficiently supporting and dispersing an applied punching crack by providing a structure of the present invention.
