The present invention relates to a method for constructing a floor plate of a prefabricated building, and more particularly, to improve the weight reduction and vibration performance of a concrete floor plate of a prefabricated building manufactured in the form of a modular unit.

In general, the prefabricated building basically forms a rectangular frame, and in the case of the bottom plate of the prefabricated building, a form is installed and then made in a concrete pouring method.

As a prior art, in Patent No. 947297, the formwork is first installed for concrete placement, and then reinforcement, concrete placement, curing, and form dismantling are performed.

However, in the prior art, since the work of installing and dismantling and cleaning the formwork is necessary repeatedly, there is a problem in that a cost increases due to an increase in work period, workforce, and equipment.

In addition, the conventional prefabricated building has a low thermal insulation performance, the weight of the building is increased due to the thickness of the floor plate has a problem that the site movement and construction is difficult.

The present invention has been proposed to improve the problems in the above-described conventional concrete floor plate construction, it is possible to quickly configure the concrete floor plate without using a separate formwork, and to increase the insulation with lighter weight of the structure The purpose is to make it possible.

The present invention for achieving the above object is a frame manufacturing step of producing a frame frame of the rectangular frame by connecting a plurality of vertical frames and each vertical frame horizontally; A first heat insulating material disposing step of disposing a first heat insulating material on the bottom of the manufactured frame; A second heat insulating material seating step of seating the plurality of second heat insulating materials spaced apart from each other at a predetermined interval (d) on the first heat insulating material; Reinforcing bar reinforcement step for reinforcing the reinforcing bar on the second insulating material; A concrete placing step of placing concrete on an upper portion of the second insulation to prevent the rebar from being exposed; It characterized in that it comprises a; curing step of curing the poured concrete.

Prefabricated building floor plate construction method of the present invention, without the use of a separate formwork exhibits the effect that the concrete floor plate using a heat insulating material can be quickly constructed.

In particular, through the multi-layered structure of the heat insulating material to improve the heat insulation of the bottom plate and to achieve a light weight of the structure, it shows the advantages of forming a form of effective structural reinforcement of the bottom plate.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the process of forming the bottom plate of a prefabricated building according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6.

Frame Creation (ST 1)

First, in manufacturing the frame frame 10 of the rectangular frame form as shown in Figure 2 by forming an integral structure to connect a plurality of vertical frames (11) standing in the vertical direction to the horizontal frame 12 at the upper and lower ends of each other As described above, the frame frame 10 is formed to form a prefabricated building.

<First Insulation Material Placement> (ST 2)

The first heat insulating material 20 such as styrofoam is disposed on the bottom of the skeleton frame 10 manufactured as described above, as shown in FIG. 3, and the first heat insulating material 20 forms a horizontal frame 12 forming a periphery of the bottom. By making the same size as the rectangular shape of to achieve a state in close contact with the horizontal frame (12).

In addition, the first insulating material 20 disposed on the bottom surface is preferably connected to the horizontal frame 12 using a wire (not shown) so as not to flow or separate in the manufacturing process.

<Sealing Second Insulation Material> (ST 3)

In addition, the second insulating material 30 is seated on the upper surface of the first insulating material 20. At this time, the second insulating material 30 is manufactured in a plurality of small sizes to form a mutually spaced interval d as shown in FIG. It is settled in the position to be made.

That is, each of the second insulating material 30 is spaced apart from each other by a constant spacing interval (d), as well as the second insulating material 30 to form a constant spacing (d ') with the horizontal frame 12 at the top thereafter. The thickness of the concrete layer to be poured is relatively reduced so that the bottom plate can be lightened.

In addition, by forming a spacing (d, d ') to form a space in which the concrete and reinforcing bar can be arranged in the corresponding area it is possible to minimize the strength decrease due to the thickness of the concrete layer.

Reinforcement (ST 4)

As such, when the lamination work of the first and second insulation materials 20 and 30 is completed, the reinforcing bar 40 is disposed as shown in FIG. 5 at the upper portion and the spaced intervals d and d '.

At this time, it is preferable to install the stud bolt 13 in the horizontal frame 12 to be embedded in the concrete to be poured later to increase the bonding force.

Concrete casting (ST 5)

Then, when the reinforcement 40 reinforcement work is completed, the concrete 50 is poured into the corresponding portion to form a floor concrete layer as shown in FIG.

In this case, the poured concrete 50 forms a predetermined thickness on the insulation 20 and 30, and flows into each space of the second insulation 30, as well as the first insulation 20 and the second insulation 30. As it comes into contact with each other, the mutual adhesion can be increased.

Curing (ST 6)

When the poured concrete 50 is cured as described above, the insulation 20 and 30 and the concrete 50 form a combined form in mutually uneven form, so that the overall strength of the bottom surface can be achieved.

7 shows the bottom plate structure completed by constructing the finishing mortar layer 70 and the bottom panel 80 on the concrete 50. Reference numeral 90 denotes an outer wall sandwich panel, respectively.

Therefore, when the bottom plate is formed through the method of the present invention, it can be seen that it is possible to quickly and easily manufacture a lightweight bottom plate having improved insulation without using a separate formwork.

On the other hand, Figure 8 shows a state in which the fastening pin 60 according to another embodiment of the present invention is used.

That is, in the second heat insulating material seating step (ST 3) to be coupled to the first heat insulating material 20 in a plurality of places using the fastening pin 60 to support the position of the second heat insulating material 30, The fastening pin 60 penetrates the second insulating material 30 vertically so that the lower end of the fastening pin 60 is inserted into the first heat insulating material 20, and the upper part of the fastening pin 60 is the second heat insulating material 30. ) To be exposed to the upper surface is to be embedded in the concrete 50 in the concrete placing step (ST 5) to form an integral structure.

Therefore, the first insulation material 20 and the second insulation material 30 are coupled to the concrete 50 by the fastening pins 60. In this case, the fastening pin 60 is formed of a screw thread 61 in the form of a screw along the outer circumferential surface to improve the fastening force with the first heat insulating material 20, the second heat insulating material 30, and the concrete 50. By using it to improve the fastening force can be maintained a more stable coupling state.
