Description
The present invention relates to a method for constructing a building structure using a beam and an ultra lightweight concrete in a short period of time. More particularly, the present invention relates to a vertical and horizontal structure for supporting a load, The present invention relates to a method for constructing a multi-story building in a short period of time by placing a structure (exo-squeegee), a deck plate forming a floor and a ceiling together, or selectively placing and curing an ultra- . In addition, the present invention relates to a construction method capable of improving the vibration resistance of a building structure by applying a beam of a prefabricated structure to attenuate vibrations.
Generally, the structure of a building is divided into a wooden structure, a brick structure, a cement block structure, a stone structure, a reinforced concrete structure, a steel structure, and a steel reinforced concrete structure depending on the material of the subject structure. Among them, the reinforced concrete structure, the steel structure, and the steel reinforced concrete structure are mainly used for the construction of the multi-story building. These structures are structures that supplement the weak points of tensile stress of concrete with reinforcing aggregates such as steel bars, steel sheets, steel pipes, etc., and reinforced concrete structures are constructed by installing reinforced concrete structures and forming concrete on the outside of the reinforced concrete structures. The steel structure is constructed in such a way that the important skeleton part is assembled with a forcing member, the forcing member is formed into a form, or a concrete form is installed by installing a separate formwork. The steel reinforced concrete structure is constructed by mixing the reinforced concrete structure with the steel concrete structure.
Conventionally, when a multi-layered building is constructed, a method of sequentially applying layers one by one has been used. In other words, after the concrete is cured after installing the lowest reinforced bar or steel structure and the concrete is installed by installing the formwork, reinforcing bars and steel structures are installed on the upper layer, and concrete installation and curing are repeated. Respectively. Accordingly, the construction period of the building is doubled according to the number of the floors, and thus it takes a lot of time to construct the multi-story building.
Furthermore, since the conventional construction method has to be removed after the concrete is cured after installing the formwork, the construction time is further elongated, and labor and cost are additionally required.
In addition, when the multi-story building is constructed by the above-described conventional method, the means for attenuating the vibration is not provided and the seismic resistance is degraded. In order to solve this problem, the seismic design has to be applied with additional time and cost.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a high-speed construction method of a building structure that can simultaneously construct concrete multi-layer buildings in a short time by pouring concrete into a plurality of layers.
It is another object of the present invention to provide a high-speed construction method of a building structure that does not need to remove formwork after concrete curing, thereby further reducing the time and cost required for construction.
It is another object of the present invention to provide a high-speed construction method of a building structure capable of attenuating vibrations of a tensile structure to improve the vibration resistance of a building at a lower cost.
In order to accomplish the above object, there is provided a method of high-speed construction of an earthquake-resistant building structure using a beam and an ultra-lightweight concrete, comprising the steps of: installing a lowest load supporting structure by coupling a plurality of beams; Installing a load supporting structure constituting one or more upper layers by combining a plurality of beams on the uppermost load supporting structure; Installing at least one of a mesh-like structure (exo-keelitone) for forming a wall and a deck plate for forming a slab in the lowermost and upper-layer load supporting structures; And placing the concrete in the interior of the mesh-like structure (exo-squeegee) or on top of the deck plate.

The load supporting structure may be any one of an H-shaped beam, an I-shaped beam, an L-shaped beam, a tubular beam, or any type of beam. Preferably, the bent support beam is an H-shaped beam . In this case, it is more preferable that the shaped beam is combined with a plurality of bolts.
It is preferable that the deck plate is a deep deck plate having a large step between the protruding portion and the recessed portion.
The mesh-like structure, which is a mesh-like structure, may have a bar or beam-shaped frame member coupled to a meshed member spaced a predetermined distance from each other. The mesh-like structure, which is a mesh-like structure, can be used to form building structural members in all directions as well as vertical and horizontal directions, and conventional molds are used to remove concrete after curing, The structure (meshed structure) can be used as it is without being removed after curing to increase the structural strength. In addition, unlike conventional formwork, it can be of mesh type, meshed type, bulk type, hollow type, box type, and can be used for curing concrete. It can also be used as a structural member in all directions, such as vertical and horizontal, and also as an auxiliary member forming the structural member, and also as a structural member itself.
The concrete is preferably a lightweight concrete containing an artificial lightweight aggregate. The artificial lightweight aggregate is not limited to the material but may include any lightweight material, and may include, for example, a foamable polymer (synthetic resin), a straw, and a primitive.
It is preferable that a coupling module in which a concrete injection pipe is attached to and detached from a side portion of the mesh structure (exo-squeegee) is provided.
In addition, a horizontal member between the layers can be formed as a concrete injection pipe. A horizontal member between the layers may be provided in a box shape and a hinge portion may be formed at both end portions of the box-shaped horizontal member so as to be rotatable. By rotating the rotatable horizontal member, concrete or the like can be input. The horizontal member may be formed to penetrate up and down, and may include an interlayer plate or a comb-shaped interlayer member capable of interlayer buffering at an interlayer boundary after being laid in a lower layer portion. In some cases, the interlayer plate can relieve direct pressurization of concrete or the like downward by using a conventional flat plate, or may be formed so as to pass through a piercing material such as a mesh or a comb. In any case, any structure can be formed so long as it is a structure capable of mitigating and dispersing a direct load from the top after the placement.
According to the present invention, a tensile structure including a beam can be assembled / combined to form a multi-layer structure, and concrete can be placed thereon to construct a plurality of layers at the same time, thereby shortening the construction period of multi- It is possible to reduce the cost required for the system.
In addition, since a wall portion of a building is constructed by using a mesh structure that also functions as a tensile structure and a formwork, there is no need to remove a form after construction, thereby improving the convenience of construction and further reducing construction cost and time have.
In addition, by applying a beam combined with a channel-shaped plate-shaped steel material with a plurality of bolts as a tensile structure, vibration is attenuated through the bolt coupling portion, thereby improving the vibration resistance of the multi-layered building with less time and cost.

Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.
FIGS. 1A to 1N show an embodiment of a high-speed construction method of a building structure using a beam and an ultra-lightweight concrete according to the present invention. The construction method of the present invention will now be described with reference to the drawings.
First, as shown in FIG. 1A, the lowest layer (one layer) load supporting structure is installed. This load-supporting structure combines a plurality of vertical beams serving as pillars and a plurality of horizontal beams serving as beams to form a structure supporting the load of the building. The vertical beam and the horizontal beam may be various types such as an H-beam, an I-beam, an L-beam, and a tubular beam. Preferably, the H-shaped beam is formed by oppositely coupling the female-type beams bent in the form of a long channel so as to open outward. At this time, it is preferable that a plurality of bolts are used for the coupling of the double-sided beams. This structure has the effect of attenuating the vibration at the bolt connecting portion, resulting in useful results for improving the vibration resistance.
Meanwhile, in the illustrated embodiment, a structure in which four vertical beams and four horizontal beams are combined is illustrated. However, the present invention is not limited thereto, and a larger number of vertical beams and horizontal beams may be formed in one layer So as to form a load-supporting structure.
1B, a two-layer deck plate is installed as shown in FIG. 1C by combining vertical beams and horizontal beams on the upper part of the single-layer structure as described above, as shown in FIG. 1B . At this time, as shown in FIG. 3, the deck plate is preferably a deep deck plate having a large step between the protruding portion and the recessed portion. This improves the strength of the deck plate, which is useful for increasing the strength against impacts when pouring concrete, and reducing or eliminating the need for additional installation of the lower reinforcement member. For example, as shown in Fig. 2, it is possible to provide a sufficient supporting force even by installing only a small number of male reinforcements.
Next, a three-layer load supporting structure is installed as shown in FIG. 1D. At this time, it is preferable that the mesh structure (exoskeleton) is simultaneously installed on the one-story load supporting structure.
As shown in FIGS. 8 to 10, the mesh-like structure (exo-squeegee) is formed by connecting a frame member having a bar shape or a beam shape to a mesh member spaced apart from each other by a predetermined distance, And may have various structures and shapes corresponding to the formwork for a wall in addition to the exemplified structure.
If the load supporting structure, the mesh structure (exo-keelite) and the deck plate are additionally provided as an upper layer such as four or five layers as shown in FIG. 1E to FIG. 1H, the frame and the formwork are completed .
In this state, the wall of each layer and the bottom concrete are simultaneously poured. At this time, it is preferable to pour the concrete into the mold from the side of the mesh-like structure (exo-sketch) of each layer of the wall part, and the concrete is laid on the upper part of the deck plate of each layer.
Here, the concrete is made of ultra lightweight concrete. The lightweight concrete is made by replacing the aggregate of ordinary concrete with an artificial lightweight aggregate to reduce its weight. The artificial lightweight aggregate is preferably a foamed synthetic resin such as expanded polystyrene. Conventional lightweight concrete generally has a specific gravity of about 1.4, but in the present invention, it contains a larger amount of artificial lightweight aggregate and has a much lower specific gravity (for example, a specific gravity of 1.0 or less, preferably 0.6 or less, more preferably 0.5 or less ) Lightweight concrete can be used to further reduce the load load during concrete pouring.
When concrete is laid in each layer as described above, most of the concrete laid in the mesh-like structure (exo-squeegee) as shown in Figs. 1I to 1N is accumulated in the form of being accommodated in the formwork, (Small amount is projected and discharged out of the formwork) together with the deck plate, the concrete placed on the deck plate is accumulated in the upper part of the deck plate, and the floor and the ceiling (slab) of the building together with the deck plate It accomplishes.
As shown in FIGS. 4 and 5, it is preferable to provide a coupling module for easily attaching and detaching a concrete inlet pipe for easy pouring of concrete to the side portion of the mesh-like structure (exo-squeegee) Do.
In addition, as shown in FIGS. 6 and 7, a window frame or a door frame may be installed in advance in the mesh structure (exo-squeegee) to reduce the construction time of the formwork and improve the convenience of installation.
As described above, the entire load supporting structure constituting the multi-storey building is assembled by combining the beam supporting the load of the building, the mesh structure (exo-keelite) and the deck plate, and the ultra- Since the construction of multiple layers of concrete is carried out at the same time, delay of the air and labor and cost are not caused by installing the formwork sequentially one after another and pouring the concrete as in the conventional manner, So that it can be installed at low cost.
In addition, since the mesh-like structure (exo-squeegee) constituting the load-supporting structure forms the wall of the building together with the concrete, it is not necessary to remove the form after curing of the concrete, so that the construction time and cost can be further reduced .
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
