[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 using a half slab, in which outer walls and corner walls are bound together by a steel wire or a steel bar, Which is reinforced and maximizes the coupling force between the outer wall and the corner wall and the half slab for the roof, and is also easy to assemble the two adjacent outer walls.

As is well known, houses and their corresponding buildings require various construction steps such as construction of reinforced concrete structures on foundation concrete and construction and construction, so that the economic burden due to excessive construction and construction costs Of course, the construction period is long, and after the construction is completed, there are various problems such as difficulty in remodeling and repair work.

In recent years, a prefabricated house has been constructed, which is constructed by transporting prefabricated prefabricated building modules to a construction site 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.

Considering that it is the most structurally stable to construct various buildings including a house using a concrete steel structure, Korean Unexamined Patent Publication No. 2005-0039399 (Apr. 29, 2005) discloses a structure in which protrusions and grooves are formed at the connection portions of each wall, A movable concrete assembly building is disclosed in which an insertion hole is formed in a lower base plate to fix the lower portion and the wall to each other while being fitted to each other so that the strength is increased and the leakage and dew condensation are prevented. The airtightness of the joint portion is deteriorated, the slab construction for forming a multi-layered 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.

In order to solve the above-described problems, the present applicant has developed and applied a prefabricated building structure using a half slab (Patent Application No. 10-2012-0053459).

The conventional building structure includes a plurality of outer walls formed in a reinforced concrete block structure having a seating surface vertically oriented in an inward direction on an upper surface thereof, projections formed on one side thereof, and fitting grooves formed on the other side thereof, A corner wall having a rectangular shape which is formed in a reinforced concrete block structure in which a seating surface which is perpendicular to the inner direction is formed and a projection is formed on one side and a fitting groove is formed on the other side, A floor concrete placed on the foundation concrete of the construction site so that the lower end of the outer wall and the lower end of the corner wall are integrally formed with the upper portion of the foundation concrete and the upper portion of the stirrup; And a plurality of ceiling half-sills which are seated on the seating surfaces of the seating surfaces and the corner walls and are integrally assembled 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, and a horizontal structure for dividing the floor of the building, A half slab for layer classification, a half slab for layer classification, and a topping concrete laid on the top surface of a half slab for ceiling and a half slab for roof.

A rectangular shaped trench is formed in the construction site opposite to the lower end of the outer wall and the corner wall so that the lower end of the wall is seated. The trench includes a rectangular shaped stirrup integrally woven according to the shape of the trench, The exposed portion of the lower reinforcing bar is fixed, and the foundation concrete is poured into the trench so that the lower portion of the stirrup and the lower portion of the wall are embedded.

However, in the prefabricated building structure using the conventional half slab, the structure of the half slab for roof is not robust. That is, the roof structure described above is completed by putting the topping concrete on the corresponding end portions of the pair of roof half slabs after returning to the roof shape.

Such a roof structure is a part where stress is concentrated without having a particularly reinforced structure as compared with other parts, which is the center part of the roof. Therefore, there is a problem that cracks are generated in the joining portions of the half slab for roof and the cracks are generated in the topping concrete portion placed thereon as time passes.

In addition, in a conventional building structure using a half slab, the joint between the half slab for roof and the outer wall is not firmly coupled. A pair of roofing half slabs are arranged obliquely while the top surface of the outer wall contacting the roofing half slab forms a horizontal plane so that the contact area on these is very small and accordingly the roof half slab is placed on top of the outer wall It was not firmly supported on the surface.
