1, a method (S100) of a structure including a bottom planarization method and a floor surface reinforcement method using special equipment according to an embodiment of the present invention includes a step of forming a concrete (C) As a method for forming a flat floor F by pouring and packing the ready-mix concrete R as a whole, a first step which is a pre-process step before putting the ready-mixed concrete R, a second step that a ready- And a third step, which is a post-processing step after the second step.

Hereinafter, the first step, the second step and the third step will be described in detail.

The first step is a pre-process step before the ready-mixed concrete is installed, and it includes an aligning step (S110) and a separating panel installing step (S120).

FIG. 2 is a schematic view illustrating a step of laying up a method of constructing a structure including a bottom planarization method and a floor surface reinforcement method using the special equipment of FIG.

As shown in FIG. 2, the step S110 of arranging the plurality of reinforcing bars 10 in the packaged area S may improve the durability of the concrete C after the placing and curing of the concrete R. . In this step, the reinforcing bars 10 may be arranged side by side so as to be spaced apart from each other in one direction, or may be arranged in a grid structure in order to realize higher durability, if necessary.

In the present invention, the laying step S110 is not necessarily performed and various factors such as the area of the area S to be packed, the type of the ready-mixed concrete R, and the steel fiber May be omitted in the entire process.

FIG. 3 is a schematic view showing a state in which a spacing panel is installed in a step of installing a separation panel in a method of constructing a structure including a floor planarization method and a bottom surface strengthening method using the special equipment of FIG. 1, And FIG. 5 is a schematic view illustrating a floor planarization method using the special equipment of FIG. 1, and FIG. 5 is a schematic view illustrating a floor planarization method using the special equipment of FIG. FIG. 6 is a schematic view illustrating a floor leveling method and a floor surface strengthening method using the special equipment of FIG. 1; and FIG. FIG. 1 is a schematic view showing a filling step in a step of installing a separation panel in a method of constructing a structure including the structure of FIG.

3 to 6, the step of installing the spacing panel S120 is a step of installing the spacing panel 20 in the area S to be packaged before putting the ready-mixer R, S121), a measurement step S122, a height adjustment step S1223, and a filling step S124.

In the step S120 of installing the spaced apart panels, the concrete C after curing is prevented from cracking due to expansion or contraction due to a change in the ambient temperature, , A spacing space in which the concrete C is not poured in the area S to be packed is formed, and the detailed process steps will be described in detail.

First, as shown in FIG. 4, the placement step S121 is a step of disposing the spacing panel 20 and additional components for installing the spacing panel 20 at appropriate positions in the area S to be wrapped.

In the present invention, the spacing panels 20 are arranged in a structure in which the pairs are mutually contacted and joined together by bolts. In the present invention, by using the spacing panel 20 to increase the area of the surfaces facing each other with the spacing space V relatively larger than when using the spacing panels 20 of flat shape, the durability and the durability of the concrete So that the supporting force can be maintained.

However, as shown in FIG. 3, the shape of the spacing panel 20 may be various shapes such as a linear shape, a shape in which protrusions and depressions are repeatedly formed along the longitudinal direction, and the like, Make it clear. The material of the spacing panel 20 is not limited as long as it has rigidity including plastic resin, metal, and the like.

On the other hand, in the present embodiment, the spacing panels 20 are not integrally arranged as a single structure, but a plurality of spacing panels 20 are connected to each other along an installation path. At this time, the height display portion 22 is mounted on the upper end of each of the spacing panels 20 and is used as a reference for height adjustment in a height adjustment step S1223 described later. This will be described later.

The bottom surface of the area S to be packaged is provided with a guide part 21 in which a guide groove is formed and the lower end of the spacing panel 20 is accommodated in the guide groove. Therefore, when the height of the spacing panel 20 is adjusted, the spacing panel 20 can be raised and lowered while being accommodated in the guide groove.

On the side of each of the spacing panels 20, a height adjusting portion 23 is formed to form a thread parallel to the spacing panel 20. An elevating member 24 is screwed to the height adjusting portion 23 and an elevating member 24 is connected to each of the spacing panels 20. Therefore, the spacing panel 20 also moves in accordance with the movement of the elevation member 24. [

The measurement step S122 measures the current height of the spacing panel 20 through the height display part 22 protruding from the top of each of the spacing panels 20 and compares the current height of the spacing panel 20 And ascertaining degree is determined.

That is, since the flatness and the height of the ground disposed initially for each of the spacing panels 20 are different, the height of all the spacing panels 20 must be adjusted so as to be uniformly installed in a straight line at a predetermined constant height. (S122), the height adjustment amount of each of the spacing panels 20 is determined from the height display section 22. [

5, the height adjustment step S123 may be performed using the information obtained in the measurement step S122 based on the height of the height display part 22 protruding from the top of each of the separation panels 20, Adjust the height of each spacing panel (20).

As shown in FIG. 3 (b), the height of the spacing panel 20 is adjusted so that the spacing panel 20 can be installed at a constant height, considering that the bottom surface of the package area S is formed of uneven surfaces. The operator adjusts the height of the spacing panel 20 corresponding thereto by considering the height of each height display section 22. [

That is, when the worker rotates the height adjusting portion 23, the elevating member 24 screwed thereto is raised or lowered in accordance with the rotation of the height adjusting portion 23, The elevation is also adjusted to the height. At this time, since the lower end portion of the separation panel 20 is accommodated in the guide portion 21, the separation panel 20 can be raised and lowered without departing from the predetermined position.

When the height adjustment of the specific spacing panel 20 is completed, the height display unit 22 mounted on the adjusted spacing panel 20 is moved to the neighboring spacing panel 20, and the height adjustment is performed by the above- And repeat the process.

By adjusting the height of each of the spacing panels 20 through the above-described process, all of the spacing panels 20 can be installed at a constant height along the installation direction.

As shown in FIG. 6, the filling step S124 is a step of filling the lower end space of the spacing panel 20 raised according to the height adjustment.

That is, as the spacing panel 20 is raised, a space is formed at the lower end to allow the ready-mixer R to flow in. In order to prevent this, To be isolated.

Next, a second step in which a concrete floor is formed by piling and curing a ready-mixed concrete will be described. The second step includes a placement step S130, a leveling step S140, a surface planarization step S150, and a curing step S160.

FIGS. 7 and 8 schematically illustrate the process of placing a construction method of a structure including a bottom planarization method and a floor surface reinforcement method using the special equipment of FIG.

7 and 8, the pouring step S130 is a step of placing the ready mixer R in the area S to be packaged and includes a relay device placing step S131 and a discharging device controlling step S132 do.

The concrete placing device 30 used for placing the ready mixer R in this step will be described first, and then each detailed process will be described. The concrete placing device 30 is composed of a supply device 31, a relay device 32 and a discharge device 33.

The feeder 31 temporarily stores the ready mixer R, which is disposed outside the area S to be packaged and contains cement, aggregate and water at an appropriate ratio, and is connected to a relay device 32, a discharge device 33 ).

The relay device 32 is extended from the supply device 31 in a state in which the operator is temporarily disposed at a desired position in the area S to be packed and places the supply pipe as a supply path for the ready- (33).

The relay device 32 is provided with a wheel so that it can be moved to the lower end so as to move by the driving force of the engine or the motor and the relay device 32 is stably arranged on the side of the relay device 32 And the like.

In the present embodiment, the operator is not provided with a driver's seat for boarding the relay device 32, and the operator can control the operation of the relay device through a wireless controller (remote controller). Is a special facility that moves within the area to be packaged S in a state where the end portion of the supply pipe extending from the relay device 32 is mounted.

The discharging device 33 is provided with a wheel so that the discharging device 33 can be moved by the driving force of the engine or the motor so as to be movable at the lower end like the above-described relay device, and the driving is controlled through the wireless controller .

The detailed process of this step will be described in detail based on the concrete placing device 30 described above.

The relay device arrangement step S131 is a step of temporarily arranging the relay device 32 in the area S to be packed.

One end of the supply pipe to which the ready mixer R is supplied is provided on the side of the supply device 31 and the other end is connected to the discharge device 33. [ At this time, in the process of controlling the discharge device control step (S132) described later, in the process of moving the end portion of the supply pipe to which the ready-mixer R is discharged, the central region of the supply pipe is continuously pulled in contact with the floor F, .

Therefore, in this step, the relay device 32 for relaying the supply pipe is disposed at a specific position, whereby the central region of the supply pipe, which does not need to be directly moved during placement of the ready-mixer R, is temporarily disposed at a specific position. The temporary placement position of the relay device 32 in this step can be determined in consideration of the area to be put in the ready-mixed concrete R and the moving radius of the discharge device 33. [

At this time, the distance to the discharge device 33 becomes the moving radius of the supply pipe about the position where the relay device 32 is disposed, that is, the discharge device 33 is pivotable about the relay device 32, Move. Therefore, in this step, the position where the supply pipe is to be mounted is first determined, and the position of the relay device 32 is determined after the supply pipe is mounted on the relay device 32.

On the other hand, a plurality of relay devices 32 may be provided depending on the length of the supply pipe and the area of the area S to be packed. For example, if it is assumed that two relay apparatuses 32 are used, the position of the relay apparatus 32 adjacent to the supply apparatus 31 is first arranged, and then the direction in which the relay apparatus 32 moves away from the supply apparatus 31 A relay device 32 is installed. In the case of using a plurality of relay devices 32, since a plurality of supply pipe regions are divided and arranged even in a special situation using a long supply pipe, it is possible to minimize the inconvenience that the supply pipe is shaken due to its own weight during pouring There are advantages.

The discharging device controlling step S132 is a step of placing the ready mixer R while controlling the discharging device 33 to which the end portion of the supply pipe to which the ready mixer R is discharged is connected.

In this step, while moving the discharging device 33 with the end portion of the supply pipe being moved, the ready mixer R is supplied toward the position where the placing is required. The piercing device 33 is movable within a moving radius around the relay device 32 in which the position is located. Since the operator can remotely operate the remover 33 by using the remote controller based on the remote controller RC, the operator can perform the installation in a state in which a wide field of view is secured at a point remote from the target area, It is possible to minimize the time required for casting.

Even if the discharging device 33 moves in this step, the supply pipe between the supplying device 31 and the relay device 32 moves only the necessary part without moving, so that the force required for putting the ready-mixer R is minimized As well as minimizing the portion of the supply line that is worn out due to continuous friction with the floor (F).

On the other hand, when the placement of the discharging device 33 within the moving radius is completed, the position of the relay device 32 is changed and arranged, and then the supply pipe moving part 33 is controlled to expand the pouring area. That is, the placement of the ready-mixer R in the space S to be packaged is completed by repeating the above-described relay device disposition step S131 and the discharge part control step S132.

FIGS. 9 and 10 are schematic views illustrating a principle of separating the spacing panels in the step of placing a construction method including a floor planarization method and a bottom surface strengthening method using the special equipment of FIG.

In this step, as shown in FIG. 9, the ready mixer R is laid in one region around the installed spacing panel 20 so as to be adhered to the ready mixer R which is hardened on one surface of the spacing panel 20 The guide portion 21, the height adjusting portion 23, and the elevating member 24 are separated and removed.

Thereafter, as shown in FIG. 10, the bolts connecting the one-phase spacing panel 20 in close contact with each other after the ready-mixer R is placed in another area of the spacing panel 20 are unfastened. The ready-mixed (R) shrinks with the spaced apart spaced panel 20 being cured. The pair of spacing panels 20, which are disengaged due to the shrinkage of the ready mixer R, are separated from each other to form a spacing space V therebetween. By this process, the ready-mixer R is selectively installed only in the region except the inside of the spacing space V between the spacing panels 20.

11 schematically illustrates a leveling step of a method of constructing a structure including a bottom planarization method and a floor surface reinforcement method utilizing the special equipment of FIG.

11, the leveling step S140 is a step of uniformly adjusting the height of the loaded ready-mix R, and includes steps of installing the reference display part S141, arranging the scrizing device 40, (S143).

The reference display unit installation step S141 is a step of installing a reference display unit 41 for transmitting a leveling signal to a scrambling device 40 to be described later.

In this step, it is preferable that the reference display part 41 is installed at a position where the screeding device 40 can face the package area S as a center.

In this step, the operator inputs necessary information to the reference display section 41. [ More specifically, by inputting the standard height value of the spacing panel 20 into the reference display section 41 in the preceding step of installing the spaced panel (S120), the reference display section 41 is set in the scribing device 40 So that standard height information can be provided.

The step of arranging the scription device (S142) is a step of arranging the position of the scription device 40 performing the leveling process. In this step, the scrizing device 40 is moved to the area where the scrizing is required, and then the position is temporarily placed.

Fig. 12 schematically shows the operation step of the leveling step of Fig.

12, the operating step S143 is performed by operating a screeder 42 installed at the end of the scrizing device 40, specifically, the scription device 40, Scrubbing a part of the surface of the ready-mixed concrete (R) to adjust the height of the floor to a constant level, including a screed pressing step, a screed controlling step and a vibration step.

Hereinafter, for convenience of description of this step, three axes are defined as shown in the drawing. That is, the axis parallel to the translational motion direction of the scriber 42 is defined as the x axis, and the direction parallel to the gravity is defined as the z axis.

The screer pressing step is a step of bringing the screeder 42 mounted on the screeding device 40 down along the z axis so as to be brought into close contact with the surface of the ready-made ready-mix R. The scriber 42 controls the amount of ready-made ricos R scrolled by ascending or descending along the z-axis based on the information for each position.

The scrier controlling step is a step of scrolling (finishing) part of the surface of the ready-mixed concrete by moving the screeder 42 in contact with the ready-mixed concrete R in the x-axis direction.

Meanwhile, the scriler pressing step can be performed simultaneously while performing the scrier controlling step. That is, while moving the screeder 42 in the x-axis direction, the appropriate height of the remicon is calculated in real time at each position on the x-axis of the screeder 42, thereby moving the screed 42 appropriately in the y-axis direction.

In this step, the scidding device 40 detects an optical signal or a laser generated from the reference display part 41, so that the appropriate height of the ready-made concrete can be calculated in real time.

Finally, the vibrating step is a step of applying vibration to the screeder 42.

In this step, when the movement of the scriser 42 is restricted due to accumulation of a large amount of ready-mix R during the above-described scriber pressing step and the scrier controlling step, the scriber 42 is vibrated to move It should be smooth.

It is also possible to facilitate the operation by removing the remicon (R) residue attached to the scrubber 42 through vibration.

In the meantime, this step may be performed by a method of applying vibration to the screeder 42, a method of vibrating the screed 42 along at least one of the three axes, or a method of superimposing two modes have.

In the operation step S143, the above-described scriber pressing step, the scrier controlling step, and the vibration step are not progressed in time order, but the scriber pressing step, the scrier controlling step, Or a plurality of steps may be performed simultaneously.

In other words, the operation step S143 will be described again. Even when the scriser 42 is moved down (screeder pressing step) to move along the x-axis in the state of being in contact with the surface of the ready- ), It is possible to perform precise leveling by moving up and down along the z-axis (screed pressing step). In addition, the vibration of the scriber 42 (vibration stage) can be performed even after the movement of the scriser 42 (scriser control step) or the movement is completed.

The leveling step will be described generally as follows. When the screeding device 40 is placed at a predetermined position (screed device arranging step) after the reference display part 41 is installed at a proper position (reference display part installing step) When the leveling (operation step) of the area is completed, the scrambling device 40 is moved again and the position is arranged (scrambling device fixing step) to perform the leveling (operation step) .

In addition, as shown in the drawing, the screeder 42 may be driven by a cylinder, an actuator, or the like, and may be driven in such a manner that a separate driving wheel or the like is mounted on the lower end of the screeder 42 And that the driving method of the scriser 42 is not limited to the above-described contents and drawings, and various forms can be applied.

FIG. 13 is a schematic view of a surface planarization step of a method of constructing a structure including a bottom planarization method and a bottom surface reinforcement method using the special equipment of FIG.

As shown in FIG. 13, the surface smoothing step (S150) is a step of smoothing the surface of the partially hardened concrete (R).

In this step, the flattening device 50 for flattening the contact bottom F by rotating the blade 51 is used. In FIG. 13, the operator is illustrated as performing the flattening process of the contact bottom F by being mounted on the flattening device 50 of the dual blade structure. However, in consideration of the area of the floor surface to be flattened, The planarization apparatus 50 may be used in the planarization step S150.

Specifically, the flattening device 50 may be a structure in which a worker operates a handle or a remote controller while walking without boarding, or a single blade may be applied instead of a dual blade.

In the curing step S160, concrete is formed by curing the ready-mixed concrete and the leveling completed by the above-described process. In this step, it is preferable to determine the curing time in consideration of the material and blending amount of the ready-mixed concrete, environmental conditions such as temperature, and the like.

Hereinafter, the third step, which constitutes the final step of the present invention, and which is a post-processing step of the cured concrete floor will be described in detail. The third step includes a surface strengthening step (S170) and a verification step (S180).

The surface strengthening step (S170) is a step of strengthening the surface of the concrete (C).

In particular, assuming that the floor constructed in this embodiment constitutes an indoor environment, the reinforcing agent applied is composed of a material containing lithium (Li). That is, the reinforcing agent to be applied is filled in the pores of the concrete (C), and reacts with the calcium (Ca) component of the concrete to thereby enhance the surface of the concrete during the curing step (S160) described later. Pentra-Sil® (H) is used.

If the concrete floor is exposed to the external environment, Pentra-Sil® (HDS), which has durability and resistance to calcium chloride (NaCl), should be used as the reinforcing agent to be applied. have.

However, it is needless to say that the reinforcing agent is not limited to the above-mentioned contents, but can be determined in consideration of various conditions.

The inspection step S180 is a step of inspecting the quality of the floor F on which the concrete pavement is completed, and includes a flatness and level inspection step S181 and a wear resistance inspection step S182.

FIG. 14 is a schematic view illustrating a flatness and leveling step of a construction method of a structure including a bottom planarization method and a floor surface reinforcement method using the special equipment of FIG.

As shown in FIG. 14, the flatness and level inspection step S181 simultaneously inspects the flatness and levelness of the finished floor F. FIG.

First, a path to be inspected for the flatness and the horizontality is determined, and the inspection line L is constructed accordingly. That is, since it is difficult to conduct inspection on all the surfaces of the floor F, only a part of the straight path is sampled and an inspection line L is installed on the inspection path.

When the inspection of the inspection line L is completed, the inspection is carried out by using the flatness and the horizontality inspection device 60.

The flatness and the horizontality inspection apparatus 60 used in the present embodiment includes a measurement unit 61, a contact unit 62, and an operation unit 63, and a brief inspection method will be described below.

The measuring unit 61 is a sensor for measuring a value required for flatness and level inspection on an inspection path.

The pair of contact portions 62 protrude downward from both ends of the measuring portion 61 and are rotatably installed. The flatness and the horizontality inspection apparatus 60 are arranged in such a manner that one of the contact portions 62 is in contact with the floor F and is rotated around the other so that the other contact portion 62 contacts the floor F You can advance.

On the other hand, the rotation of the contact portion 62 for advancement may be caused by pure attraction from the worker, or may be provided with a separate power source such as a motor.

The operation unit 63 is a bar-shaped structure extending upward from the measuring unit 61. The operator operates the flatness and the movement of the horizontality inspection apparatus 60 through the operation unit 63. [

The above flatness and level inspecting step S181 is performed when the operator places the measuring unit 61 in a direction parallel to the inspection line L so that the contact parts 62 on both sides come into close contact with the floor F, 61) automatically senses the data necessary for the inspection. The operator moves the measuring unit 61 rearward by moving the operating unit 63 in a state in which the measuring unit 61 on the front side is in close contact with the floor F and moves the measuring unit 61 forward , The measuring unit 61 senses this state and senses and stores data necessary for the inspection.

As the operator moves the flatness and level inspection apparatus 60 along the inspection line L in the above-described manner, continuous data on the floor F is stored in the measurement unit 61, The flatness and the horizontality of the floor F after completion of the construction can be inspected.

FIG. 15 is a schematic view of a wear resistance testing apparatus used in a method of constructing a structure including a bottom planarization method and a bottom surface strengthening method using the special equipment of FIG. 1, and FIG. 16 is a cross- And an inspection method using the inspection apparatus.

The abrasion resistance testing step S182 is a step of inspecting the abrasion resistance of the applied concrete floor F by repetitive friction.

In this step, the abrasion degree of the floor is measured and obtained as data by repetitively rubbing an object having the same material as the object to be actually contacted on the floor (F).

15, the abrasion resistance testing apparatus 70 used in the present embodiment includes a base portion 71, a fixing portion 72, a friction generating portion 73, and a driving portion 74, The inspection method will be described after briefly explaining this.

The base portion 71 is rotatably provided around a rotation axis and receives a rotational force from a driving portion 74 to be described later. The base portion 71 fixes a friction generating portion 73 to be described later.

The fixing portion 72 is for firmly fixing the abrasion resistance testing device 70 to the floor F during the inspection.

A plurality of the friction generating portions 73 are rotatably installed below the base portion 71 to cause actual repetitive friction with the floor F, and have a shape of a wheel. It is preferable that the material of the present friction generating portion 73 is made of the same material as the material of the wheel to be actually brought into contact with the concrete floor F after completion of the construction as described above.

The driving unit 74 applies rotational force to the base unit 71 and presses the friction generating unit 73 to continuously apply a predetermined load to the floor F.

Hereinafter, the abrasion resistance testing step 182 using the abrasion resistance testing apparatus 70 described above with reference to FIG. 16 will be described. First, the fixing portion 72 is fixed to the concrete floor F and the driving portion 74 is operated so that the friction generating portion 73 is brought into close contact with the load determined on the floor F.

When the friction generating portion 73 is brought into close contact with the floor F, the base portion 71 is rotated repeatedly to force wear due to repetitive friction between the friction generating portion 73 and the floor F. As the abrasion proceeds, a groove having a fine depth is formed on the floor F along the traveling path of the friction generating part 73. The driving part 74 continuously pressurizes the friction generating part 73 to control the applied load do.

It is possible to evaluate the strength of the applied floor F by checking the degree of abrasion due to repetitive friction in this step and judge whether or not it falls short of the designed degree.
