Description

TECHNICAL FIELD [0001] The present invention relates to an arched wide wale band and an arched wide wale band structure. [0002] ARCHED WIDER WIDTH WALE AND WALL STRUCTURE BY USING OF IT [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an arched wide wale band structure for use in construction of an underground structure, and an arched wide wale band structure using the same, wherein an arched reinforcement is inserted into the band to reinforce the rigidity of the wale band itself, The present invention relates to a steel pipe-inserted wale band and a strut which are improved in structure so as to be applicable to various construction sites such as construction work of a civil engineering construction site and the like.

As the steel pipe stratum market has been activated, circular or angled struts are often used for underground earthquake works. However, the belt has been using H-beams steadily as in the past.

However, in the case of the belt using the H-beam, there is a problem that the weak axis and the strong axis exist, and the weak axis is required to be strengthened against the compressive load transmitted through the wedge from the bottom wall.

In addition, although the performance of the strut is remarkably improved in recent years, the performance of the strut is relatively weakened, and most designs depend on the performance of the strut, so that even if a strut having a good performance is used, .

The straps used for temporary construction are to be stably designed for both flexural deformation and shear failure.

Generally, the warpage deformation in the wale increases in proportion to the span of the belt, although the warpage deformation varies depending on the support condition of the spot (the strut attachment position). The bending deformation of the belt increases in proportion to the square of the span as described in the case of the simple beam in which the equi-distributed load is loaded.

For this reason, in order to prevent warpage of the belt, it is necessary to reduce the interval of the strut which serves as a point, which increases the cost due to the increase of the number of strut.

In this case, the struts are arranged very close to each other within 2-3 m in most cases, and the struts arranged in such a tight arrangement are very important obstacles to obstruct the transportation of the construction materials, the transportation of the heavy equipment, and the construction work in the construction site And when this structure is installed later, it can cause a great disadvantage to the formwork or the reinforcing work, which lowers the construction efficiency due to the narrow space of the construction work space.

Korean Patent Laid-Open Publication No. 2002-0096596 discloses a method of reinforcing a belt using prestressing. In this method, there is proposed a technique of widening the space between the strands by tensioning the strands by installing additional wales on the pre-installed wale. However, the above method is expected to have some effect in widening the spacing of the strands, Since the moment distribution due to the load is different from the distribution of the moment due to the occurrence of the constant momentary magnitude, unlike the moment distribution of the parabolic shape generated by the earth pressure due to the earth pressure, there is a problem that the length of the reinforced stripe is limited have.

In addition, since the belt which supports the load transmitted from the wall is subjected to the bending deformation, since the load transmitted from the wall to the wale is transmitted to the strut while being connected with the strut, the portion in contact with the strut is affected by the shear force do. Therefore, in the wale band, there is a zone under the control by the 흼 and a zone under the control by the shearing force, and it is necessary to effectively reinforce the rigidity of the wale itself through the customized reinforcement thereof.

The present invention is realized by recognizing at least any one of the requirements or problems generated in the conventional wristband.
