Abstract

The present invention relates to a prefabricated construction structure using a half slab. A rectangular-shaped trench is formed on the bottom concrete facing an outer wall or the lower end of a corner wall so that the lower end of a wall is mounted. A rectangular-shaped stirrup integrally interlaced according to the shape of the trench is included in the trench so that an exposed part of a reinforcing bar in the outer wall and at the lower end of the corner is fixed. Foundation concrete is placed in the trench so that the stirrup and the lower part of the wall are embedded. The stirrups, upper reinforcing bars, lower reinforcing bars, and side reinforcing bars are interlaced with each other and form a rectangular-shaped beam. Loads are transmitted to the whole stirrup through the upper reinforcing bars, the lower reinforcing bars, and the side reinforcing bars and are dispersed to the whole stirrup if a partial subsidence is generated in the ground, and the large loads are applied to the part of the stirrup. Therefore, the problem where the part of the stirrup is sheared is prevented as the loads are dispersed over the whole stirrup when large loads are applied to the part of the stirrup due to the irregular strength of the ground. As such, the support for the construction structure is to be relatively stable.

Description

[0001] Prefabricated construction using half slab [0002]

The present invention relates to a prefabricated building structure using a half slab, and more particularly, to a prefabricated building structure capable of stably supporting an architectural structure even when partial settlement occurs in a soft foundation, The present invention relates to an architectural structure.

As is well known, houses and various buildings corresponding to them are constructed of reinforced concrete structures on foundation concrete, and various stages of construction such as masonry and plastering are required. Therefore, the construction cost and the construction cost are excessively increased, There is a problem in that the construction period is long, and there is difficulty in remodeling and defect repair work once the construction is completed.

In recent years, a prefabricated house has been constructed in which a construction module is transported to a construction site and assembled in advance in a factory so as to minimize the construction cost and minimize the construction period.

The conventional prefabricated house has drawbacks in that the airtightness of the assembled joint portion is lowered due to the use of a steel container or wood or the like, and the overall rigidity and structural stability of the completed building deteriorate.

In consideration of the structural stability of building various buildings including a house using a concrete steel structure, Korean Unexamined Patent Publication No. 2005-0039399 (Apr. 29, 2005) proposes a projection and a groove in a connection portion of each wall, There has been disclosed a movable concrete assembly building in which an insertion hole is formed in a foundation plate on which a bottom plate and a wall are fixed to each other so that strength is increased due to rigid fastening and leakage and dew condensation are prevented. There is a disadvantage that the airtightness of the joint part of the wall is lowered, the slab construction for forming a multi-layer structure in the building is difficult, and the roof is made of a truss and a panel, not a slab structure.

In order to solve these problems, the present applicant has developed and applied a prefabricated building structure using a half slab (Patent Application No. 2012-0003642).

Such a conventional prefabricated building structure using a half slab has a reinforced concrete block structure in which a seating surface perpendicular to the inside is formed on the upper surface, a projection is formed on one side, and a fitting groove is formed on the other side A plurality of outer walls; A reinforced concrete block structure in which a vertical surface is formed on an upper surface and a protrusion is formed on one side surface and a fitting groove is formed on the other surface of the reinforcing concrete block, A corner wall; A bottom concrete laid on a foundation concrete of a construction site, wherein the reinforcing bars are exposed on the side walls so as to be integrally assembled with the outer wall and the lower end of the corner wall; A plurality of ceiling half slabs arranged in close contact with each other to form a ceiling of a building and the frame ends being seated on a seating surface of the outer wall and a seating surface of the corner wall; A plurality of half slabs for roofs which are in close contact with each other while covering the ceiling half slab and whose edge ends are assembled integrally with the upper surface of the outer wall; A half slab for layer classification in which a frame end is integrally assembled to an inner surface of an outer wall; And a topping concrete laid on the top surface of the half slab for ceiling and the half slab for roof including the half slab for layer classification.

In order to erect the outer wall and the corner wall vertically, the floor structure is first placed on the foundation concrete of the construction site, the T-shaped horizontal holding plate is fixed in the trench, Set up the outer wall and the corner wall on the top of the plate. Then, the outer wall and the corner wall are fixed to the horizontal holding plate by using the anchor bolts, and the topping concrete is placed in the trench and closed.

However, such a conventional prefabricated building using half slabs has a structure in which a weighted outer wall and a corner wall are supported by a T-shaped horizontal holding plate.

Accordingly, the prefabricated building structure having such a structure can be applied to a small-sized building structure having a single-layer structure, but it is not suitable for a multi-layered building structure. As the number of floors of the prefabricated building structure increases, more vertical load acts on the horizontal holding plate of weak structure.

If a part of the ground is subsided due to a heavy load applied to the horizontal holding plate of weak structure, an unreasonable load acts on the horizontal holding plate of the lowered portion, so that the horizontal holding plate of the weak structure is easily sheared , Thereby causing a safety accident that collapses the building structure.
