Description

R-H structure and method for constructing the same, and a method for constructing the same,

[0001] The present invention relates to a RH structure, its form, and a construction method. More particularly, the present invention relates to a RH structure for applying an underground parking lot complex construction method (hereinafter referred to as RH construction method) And a molding method and a construction method thereof.

In the construction method of the underground parking lot, the quality and economical efficiency of the RC (Reinforced Concrete) group is remarkably lowered due to the decrease of skillful skilled workers and the increase of the cost of the temporary materials. Therefore, the PC (Precast Concrete) It has been applied in Korea since the early 2000s, reflecting the change of the parking module.

Slabs such as Multi Ribbed Slab (MRS) and Hollow Core Slab (HCS) were used as the span became shorter and the beam and column were also PC members.

As a result, the bottom support is no longer required at the time of construction, and safe quality can be ensured through factory production.

This PC method has advantages of less manpower and installation cost and quick construction, but it is difficult to apply it to the irregular section due to the characteristics of the PC produced through the mold, and even if applied, it is not economical.

In other words, in the conventional PC method, the system is composed of PC slab [MRS (roof layer), HCS (basement layer)], PC beam and PC column. The application efficiency is decreased according to site conditions (site condition, design plan).

In the construction method using the PC method, the 'construction method using the centrifugal forming hollow PC column and the cast-in-place concrete or steel column together with the centrifugal forming hollow PC column' of Korean Patent No. 0932468 (registered on Dec. 09, 2009) In the construction of the underground building structure, the centrifugally formed hollow PC column preliminarily manufactured at the factory is used as the column of the building structure, or the centrifugally formed hollow PC column reinforced with the cast concrete or the small size steel column is used, Provide structurally stable building construction methods without the need to use large size and heavy steel columns.

However, this PC method is applied as the main construction method of underground parking lot construction, but it was confirmed that the efficiency of field application of PC products is low due to various design conditions due to the nature of construction work and the field conditions.

For example, when the length of the PC beam is varied, the cost of the construction is more than necessary because each mold needs to be manufactured at the plant according to the length of the beam.

Also, in case of 1 ~ 2 span where the main house and the underground parking lot are in contact with each other, RC beams should be generated due to the construction conditions, and the slab is also constructed by RC slab, resulting in a decrease in the PC slab use area.
