Description

{Precast concrete panels and paving method using an embedded nut and asymmetric pocket using asymmetric pockets}

The present invention relates to a precast concrete panel using a buried nut and asymmetric pockets and a method of paving the same. Particularly, it is an object of the present invention to provide a precast concrete panel and a method of paving the same for an airport runway, In case of loss of concrete and asphalt pavement function including concrete, asphalt pavement flatness, old concrete and asphalt pavement of existing road are removed, and new buried nuts and asymmetric pockets Asphalt concrete, asphalt pavement, new concrete and asphalt pavement nuts which can be applied to asphalt pavement and asphalt pavement, which not only shortens the air according to road asphalt and concrete pavement by inserting and installing concrete panel, but also maintains uniform quality control. And asymmetric pockets The present invention relates to a precast concrete panel and a paving method thereof.

Generally, the soil layer is deformed when repeated wheel load is applied. Therefore, a structure is required to prevent deformation due to the vehicle between the wheel and the soil layer. The structure is composed of several layers and is called as a package.

The road pavement forming the above-mentioned package is divided into a soft pavement and a rigid pavement according to the surface treatment type. As a typical method of the soft pavement, there is an asphalt concrete pavement. As a representative method of the rigid pavement, there is a concrete pavement.

Here, the above-mentioned asphalt concrete pavement is a road pavement method which is most commonly applied since there are many technical know-how in domestic, because it is possible to pass the vehicle in a few hours after installation.

However, since asphalt and concrete pavement are vulnerable to high temperatures and static loads, most of the pavement damage is in the form of permanent deformation such as rutting and surface pavement, and maintenance such as repackaging every 5 years due to poor durability There is a problem in that the economic efficiency is poor.

Meanwhile, it is known that the above-mentioned concrete pavement is superior in durability and maintenance cost as compared with the ascon pavement. There are various patch pavement methods for the damage of the concrete pavement, and the bonded pavement, There is an overlay and an unbonded overlay which installs asphalt between the existing pavement and the new pavement, followed by concrete overlaying.

However, in the concrete pavement described above, a curing period is required for a certain period of time in order to obtain a predetermined strength, which may cause a great deal of trouble to the vehicle passage, and also cracks generated on the lower surface may affect the upper concrete pavement surface .

In order to solve the above problems, a precast concrete panel using a landing nut for asphalt pavement and asymmetric pockets and a manufacturing method thereof have been proposed in Japanese Patent No. 10-0687210.

As shown in these drawings, the conventional precast concrete panel using the buried nuts for road pavement and the asymmetric pockets includes a panel body 1 made of concrete and another panel body 1 adjacent to the panel body 1, (2) and / or a slot slot (3a) through which a mortar is fed, wherein the connecting member (2) and the charging slot (3) 3 are formed to correspond to the adjacent panel bodies 1, respectively.

A foam gasket 4 is formed on the lower surface of the panel body 1 to serve as a rim for the grout and a ground penetrating vertically through the panel body 1 for grouting into the foam gasket 4. [ And a ground distribution groove 4b is formed on the lower surface of the panel body 10 so as to communicate with the ground port 4a.

The pre-cast concrete panels using the asphalt padding and the buried nuts for road paving constructed as described above are planarized and then installed on the base layer in a state where a plurality of pre-cast concrete panels are manufactured using a formwork.

The pre-cast concrete panel using the above road packing packing nut and asymmetric pockets is sequentially connected by using the connecting member 2 and the charging slot 3. The mortar is injected through the slot grout port 3a of the panel So as to fix the connecting member 2 coupled to the charging slot 3.

When the mortar is injected through the ground port 4a, the mortar is supplied into the foam gasket 4 through the ground distribution groove 4b communicated with the ground port 4a to improve the flatness of the panel.

However, the conventional pre-cast concrete panel using the buried nuts for road pavement and asymmetric pockets is only horizontally adjusted by the mortar injected into the ground distribution groove 4b communicated with the ground port 4a after the lower base layer is processed flat It is very difficult to control the horizontal level of the lower base layer and it is very difficult to adjust the horizontal level of the panel because the package is raised by the lean concrete in the domestic highway.

In order to solve the above problems, a precast concrete panel using a filling nest for road pavement and asymmetric pockets has been proposed in Japanese Patent No. 10-0662015.

FIG. 3 is a perspective view 2 showing a conventional pre-cast concrete panel using a buried nut for road paving and asymmetric pockets, FIG. 4 is a cross-sectional view showing a pre-cast concrete panel using a buried nut for road paving and a non- to be.

As shown in these drawings, the conventional precast concrete panel using the buried nuts for road pavement and the asymmetric pockets includes a panel body 10 made of concrete and another panel body 10 adjacent to the panel body 10 And a filling slot (30) communicating with the slot grout port (12) to which the mortar is supplied and which is provided with a connecting member (20) protruding on at least one surface of the outer circumferential surface so as to be engaged with the pre - cast using the asymmetric pocket In the concrete panel, a plurality of height adjusting means 40 may be installed inside the panel body 10 to adjust the level of a plurality of panel bodies 10 which are coupled to each other at the time of road pavement.

The height adjustment means 40 includes a nut member 41 provided in a through hole 13 vertically penetrating the panel body 10 and a fixing member 42 protruding from the outer circumferential surface of the nut member 41, And a bolt member 43 screwed to the nut member 41 through the through hole 13 and engaged by a tool.

In the precast concrete panel using the buried nuts for road paving and the asymmetric pockets of the prior art, the lower base layer can be flattened by the height adjusting means, but the fine horizontal adjustment of the upper base layer is a very difficult problem have.

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

6 to 13, the precast concrete panel P using the buried nuts and asymmetric pockets according to the present invention comprises a concrete panel 100 composed of at least two rectangular divided bodies having a predetermined thickness and width, ; A plurality of asymmetric pockets (200) cut out at predetermined intervals at a lower side of a side surface of the concrete panel (100) so as to have a predetermined shape; A grouting inlet 300 communicating with an asymmetric pocket 200 formed at the lower side of the side wall of the concrete panel 100 and injecting the grout material; A grouting outlet 310 communicating with the asymmetric pocket 200 through the upper portion of the concrete panel 100 while being spaced apart from the grouting inlet 300 by a predetermined distance and discharging the grout material injected through the grouting inlet 300, Wow; An upper open embedding nut 400a or a through type embedding nut 400b which is installed at a predetermined position on the inner side surface of the concrete panel 100 and is vertically buried so as to be opposed to each other in the transverse direction of the concrete panel 100, Wow; A mortar injection groove 500 connected to a side surface of the asymmetric pocket 200 and formed at an edge of the concrete panel 100; A through hole (700) formed through the concrete panel (100) between the asymmetric pockets (200) and having a predetermined diameter in the longitudinal direction; And a steel bar 800 or a steel wire 900 inserted into the through hole 700.

That is, the pre-cast concrete panel P using the buried nuts and the asymmetric pockets according to the present invention has the concrete panel 100, the asymmetric pockets 200, the grouting inlet 300, the grouting outlet 310, The through hole 700, the steel bar 800, or the steel wire 900 are bonded to each other through the through holes 400a and 400a or the through hole type buried nuts 400b and the mortar injection holes 500,

Here, the concrete panel 100 is a structure composed of at least two rectangular divided concrete blocks having a predetermined thickness and width.

Particularly, since the concrete panel 100 is generally made of a reinforced concrete structure reinforced with reinforcing steel since it is strong against compression but weak to tensile, there is a possibility that cracks are generated in the concrete panel 100 due to an upper load. When 100 parts by weight of concrete composed of cement, sand and gravel are mixed with 10 to 15 parts by weight of a crack preventing agent composed of 25% by weight of Portland cement, 50% by weight of calcite and 25% by weight of magnesia, Cracking of the concrete panel 100 can be prevented in advance.

The surface of the concrete panel 100 is coated with a surface strengthening agent prepared by mixing bitumen, monomer, powder filter, UV blocker, olic acid, carboxylic acid (Carboxylic Acid), and dibutyl phthalate It is possible to prevent the concrete panel 100 from being damaged by the overburden load caused by the aircraft or the heavy equipment vehicle.

Then, the photocatalyst is applied on the upper surface of the concrete panel 100 or the upper surface of the surface strengthening agent.

In particular, the photocatalyst was prepared by dissolving 0.57 mol / l TiO2 sol prepared from Ti [OCH (Cl3) 2] 4 and (CH3) 2 CHOH, 0.44 mol SiO2 sol prepared from C8H20O4Si and (CH3) / l and ZnO (sol) prepared from Zn (C2H3O2) 2, 0.50 mol / l of at least one metal ion selected from the group consisting of Ag, Zn and Cu, 40% of sol (sol), 9% of ZnO sol (sol) and 1% of at least one metal ion selected from Ag, Zn and Cu.

The photocatalyst has a function of decomposing / removing the contaminants attached to the concrete panel, NOx, SOx, odorous gas, etc. and sterilizing microorganisms by the photochemical reaction of the photocatalyst.

That is, the above-mentioned photocatalyst forms titanium dioxide (TiO2) ultrafine particles having excellent photocatalytic activity and supports at least one of metal ions of Ag, Zn, and Cu, thereby being excited in the valence band by irradiation of ultraviolet rays, The photochemical reaction is sufficient at a small amount of ultraviolet energy by suppressing the recombination of electrons in the electron hole in the earliest time in the valence band and maximizing the active point of the photochemical reaction. The deodorizing effect, the protective effect, and the sterilizing effect can be further exerted by the sterilization mechanism.

23, the asymmetric pockets 200 are formed by cutting a plurality of the asymmetric pockets 200 so as to have a predetermined shape at a predetermined interval below the edge side surface of the concrete panel 100, that is, Is a fine groove.

The reason why the asymmetric pockets 200 are formed on the lower side of the concrete panel 100 in such a shape is to avoid interference with the dowel bars 600 installed on the old concrete pavement O. [

The reason why the asymmetric pockets 200 are formed is that if the upper and lower portions of the pockets of the precast concrete panel P using the buried nuts and asymmetric pockets are symmetrical or the lower section is large, The precast concrete panel (P) and the grout material using the buried nuts and the asymmetric pockets are separated by the vibration and impact caused by the passing load on the upper part of the cast concrete panel (P), that is, the heavy equipment or the movement of the aircraft. This is because the packaging function of the precast concrete panel P using the asymmetric pocket is lost.

Particularly, the cross-sectional shape of the joining asymmetric pockets 200 between the buried nuts and the precast concrete panels P using the asymmetric pockets is determined by the width of the upper portion and the width of the lower portion 220, (P) and grout material using asymmetric pockets and buried nuts due to vibrations and shocks caused by heavy equipment or aircraft movements. .

Accordingly, as described above, a precast concrete panel P using a buried nut and an asymmetric pocket is manufactured and installed. A pre-cast concrete panel P using a buried nut and an asymmetric pocket, a pre- The dowel bar 600 and the tie bar 610 are installed in the asymmetric pocket 200 between the cast concrete panel P and the old concrete pavement O and then the precast concrete panel P using the buried nuts and the asymmetric pockets, The horizontal adjustment and the height adjustment of the precast concrete panel P are completed and the lower and the side of the precast concrete panel P using the buried nuts and the asymmetric pockets are grouted to complete the installation of the precast concrete panel P using the buried nuts and the asymmetric pockets , The passing load on the precast concrete panel (P) using the buried nuts and the asymmetric pockets, that is, the vibrations and shocks caused by the heavy equipment and the aircraft However, there is an effect that the material of the precast concrete panel (P) using the buried nuts and asymmetric pockets and the grouting material can not be separated.

The asymmetric pockets 200 are formed with connection holes 250 of circular holes on the surface of the concrete panel 100 where the connection ports 250 or the asymmetric pockets 200 are exposed, A taper 260 having a diameter gradually decreasing from the surface of the concrete panel 100 toward the inside thereof is formed.

In this configuration, the connecting port 250 is simply connected to the precast concrete panel P using the buried nuts and the asymmetric pockets in a state where no separate pockets are formed on the lower part of the precast concrete panel P using the buried nuts and the asymmetric pockets. And the grooved material is filled in the connector 250, and the dowel bar 600 and the tie bar 610 can be installed and used.

Meanwhile, the dowel bar 600 is inserted in the lateral direction of the asymmetric pocket 200. After filling the inside of the asymmetric pocket 200 with an epoxy or a chemical resin, One side of the dowel bar 600, that is, one half of the total length of the dowel bar 600 is inserted and restrained, and the other side dowel bar 600 is fastened to the precast concrete panel P using another embedding nut and asymmetric pockets Is fixed to the connection port (250) of the asymmetric pocket (200) or the old concrete pavement (O) through an epoxy or a chemical resin.

The tie bar 610 is inserted in the longitudinal direction of the asymmetric pocket 200. After filling the inside of the asymmetric pocket 200 with an epoxy or a chemical resin, One half of the entire length of the tie bar 610 is restrained by inserting one half of the tie bar 610 and the other half of the tie bar 610 is fastened to the precast concrete panel P using other embedding nuts and asymmetric pockets Is fixed to the connection port (250) of the asymmetric pocket (200) or the old concrete pavement (O) through an epoxy or a chemical resin.

The grouting injection port 300 communicates with the asymmetric pocket 200 formed at the lower side of the lower portion of the concrete panel 100 and is filled with grout material.

Here, the grout material is composed of a grout material at a very high speed, ultra low speed mortar, cement milk, cement mortar, self-healing mortar, resin mortar, chemical liquid, epoxy resin and the like.

The grouting outlet 310 communicates with the asymmetric pocket 200 through the upper portion of the concrete panel 100 while being spaced apart from the grouting inlet 300 by a predetermined distance and at the same time, It is a part formed so that the ash can be recognized visually.

The upper open embedding nut 400a or the penetration type embedding nut 400b is composed of a nut 410 having a predetermined inner diameter and is supported horizontally on both sides of the nut 410, And a plurality of the concrete panels 100 are installed vertically so as to be opposed to each other in the lateral direction of the concrete panel 100.

The upper open embedding nut 400a or the penetration type embedding nut 400b has a structure in which the support part 420 is installed on the nut 410 before installing the embedding nut and the asymmetric pocket on the precast concrete panel P A mold is installed when the upper open embedding nut 400a or the penetration type embedding nut 400b is installed in the precast concrete panel P using the embedding nut and the asymmetrical pocket and the upper open embedding nut 400a The upper open embedding nut 400a is attached to the precast concrete panel P using the embedding nut and the asymmetric pocket, and the upper open embedding nut 400a is installed on the pre-cast concrete panel P using the embedding nut and the asymmetric pocket. Or a through type buried nuts 400b are embedded.

That is, the upper open embedment nut 400a is located on the upper side of the precast concrete panel P using the buried nuts and the asymmetric pockets, and the lower open end of the precast concrete panel P, Is not a structure that penetrates entirely from the upper surface to the lower surface of the substrate P.

The through type buried nuts 400b are positioned below the precast concrete panels P using the buried nuts and the asymmetric pockets and are entirely penetrated from the upper surface to the lower surface of the concrete panel P. [

Therefore, by using the upper open embedding nut 400a and the through type embedding nut 400b, the function of the precast concrete panel P using the embedding nut and the asymmetric pocket can be performed can do.

That is, by using the upper open embedding nut 400a or the through type embedding nut 400b provided on the precast concrete panel P using the embedding nut and the asymmetric pocket, the embedding nut and the asymmetric pocket are used to form the precast concrete panel P ) Can be combined with a height adjustment function including horizontal adjustment.

The mortar injection holes 500 are formed in the lower part of the edge of the precast concrete panel P using the buried nuts and the asymmetric pockets and the precast concrete panels P using the asymmetric pockets A certain portion is a cut-formed space.

The mortar injection grooves 500 can greatly reduce the number of grouting injection ports 300 installed.

The through holes 700 are formed in the longitudinal direction of the concrete panel 100 between a plurality of asymmetric pockets 200 formed in the concrete panel 100 with a predetermined diameter from one end to the other end of the concrete panel 100 And a through hole is formed through the inside of the concrete panel 100.

The through hole 700 is a hole for inserting the steel bar 800 or the steel wire 900 to be tightly coupled between the concrete panel 100 and the concrete panel 100.

On the other hand, the steel bar 800 or the steel wire 900 is installed so as to integrally connect the precast concrete panels by tightly connecting them.

Here, the steel rod 800 is a rod having threads formed at both ends thereof.

A nut 820 is screwed to both ends of the steel rod 800 and a grouting injection pipe 830 is formed in the nut 820.

The grouting injection pipe 830 is formed by inserting the steel rod 800 embedded in the tube 810 into the through hole 700 and then filling the clearance between the through hole 700 and the steel rod 800 with the grout material, .

Accordingly, when the grout material is charged through the grouting injection pipe 830, the steel rods 800 and the inside of the through holes 700 are filled tightly and integrally move between the concrete panels 100, Can be maximized.

A steel wire 900 may be used in addition to the steel bar 800 if necessary. When the steel wire 800 is inserted into the through hole 700, a fixing hole 910 is formed in the through hole 700 A steel wire 900 is inserted into the fixing hole 910 and used.

Here, it is noted that the steel wire 900 may be used by prestressing at an anchorage fixing point, as needed, for maintenance purposes.
