Description

[0001] Precast concrete panels and their installation method [0002]

The present invention relates to a precast concrete panel and a method for installing the precast concrete panel, and more particularly, to a method for improving the flatness of a concrete or an asphalt pavement due to cracks and breakage in concrete or asphalt pavement inside and on the surface of an airport runway, heavy vehicles, heavy equipment, If concrete or asphalt pavement is lost, the aged concrete and asphalt pavement of the existing road are removed and the precast concrete panel manufactured at the factory is separately installed and installed. Asphalt pavement, new concrete, and precast concrete panel which can be applied to asphalt pavement, and a method of installing the same, which can not only shorten the air significantly but also maintain uniform quality control.

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 compared with the ascon pavement, and there are various patching methods for the damage of the concrete 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-described problems, a precast concrete panel for road pavement and a manufacturing method thereof have been proposed in Japanese Patent No. 10-0687210.

FIG. 1 is a perspective view 1 showing a conventional precast concrete panel for road pavement, and FIG. 2 is a sectional view 1 showing a conventional precast concrete panel for road pavement.

As shown in these drawings, the conventional precast concrete pavement concrete panel for road pavement comprises a panel body 1 made of concrete and at least one of the surfaces on the outer circumferential surface to be joined to another panel body 1 adjacent to the panel body 1 And a charging slot 3 communicating with the slot grout port 3a to which the mortar is supplied, wherein the connecting member 2 and the charging slot 3 are connected to the adjacent panel body 3, (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 panel for road pavement constructed as described above is planarized and then installed on the base layer in a state where a plurality of the precast concrete panels are manufactured using a formwork.

The pre-cast concrete pavement for road pavement is installed while being sequentially connected using the connecting member 2 and the charging slot 3. The mortar is injected through the slot grout port 3a of the panel to form the inside of the charging slot 3 Thereby fixing the coupled connecting member 2.

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, in the conventional precast concrete pavement for road pavement, after the lower base layer is treated smoothly, the level is adjusted only by the mortar injected into the ground distribution groove 4b communicated with the ground pot 4a, It is difficult to adjust the horizontal level of the panel because it is very difficult to control and the pavement is raised by lean concrete as a domestic highway.

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

FIG. 3 is a perspective view 2 showing a conventional precast concrete panel for road paving, and FIG. 4 is a sectional view 2 showing a conventional precast concrete panel for road paving.

As shown in these drawings, the conventional precast concrete pavement concrete panel for road pavement comprises a panel body 10 made of concrete, and at least one surface on the outer circumferential surface to be joined to another panel body 10 adjacent to the panel body 10 And a charging slot (30) communicating with the slot grout port (12) to which the mortar is supplied. The precast concrete panel for road paving includes a plurality of A plurality of height adjusting means 40 are provided to adjust the horizontal position of the 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.

The conventional precast concrete panel for road pavement having the above-described structure can smoothly process the lower base layer by the height adjusting means, but it is practically very difficult to horizontally adjust the upper base layer.

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

6 to 13, the precast concrete panel according to the present invention includes at least two concrete panels 100 each having a predetermined thickness and width; A plurality of pockets (200) cut out at a predetermined interval at a lower portion of a side surface of the concrete panel (100) so as to have a predetermined shape; An upper open buried nut 300a or a through buried buried nut 300b, which is installed at a predetermined position on the inner surface of the concrete panel 100 and is vertically buried so as to be opposed to each other in the lateral direction of the concrete panel 100, .

That is, the precast concrete panel P according to the present invention is composed of the concrete panel 100, the pockets 200, the upper open buried nuts 300a, or the through buried buried nuts 300b.

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.

In addition, the pockets 200 are formed at the lower side of the edge of the concrete panel 100 so as to have a predetermined shape and have a predetermined shape.

The reason why the 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 400 installed on the old concrete pavement O. [

A circular hole connection port 250 is formed on the surface of the concrete panel 100 where the connection port 250 or the pocket 200 is exposed as needed. And is formed into a taper shape whose diameter gradually decreases from the surface of the substrate 100 toward the inside thereof.

This configuration can be achieved by simply forming the connection port 250 in the precast concrete panel P in a state where no separate pockets 200 are formed under the precast concrete panel P, It is also possible to charge the ash and use the dowel bar 400 and the tie bar.

Meanwhile, after the dowel bar 400 is inserted in the lateral direction of the pocket 200, the epoxy 200 or the chemical resin is filled in the pocket 200, One side of the well bar 400, that is, one half of the total length of the dowel bar 400 is inserted and restrained, and the other side dowel bar 400 is pushed into the pockets 200 of the other precast concrete panel P or the old concrete pavement O is fixed to the connector 250 through an epoxy or a chemical resin.

The upper open embedding nut 300a or the penetration type embedding nut 300b is composed of a nut 310 having a certain inner diameter and is supported horizontally on both sides of the nut 310, 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 300a or the penetration type embedding nut 300b has a structure in which the support part 320 is installed on the nut 310 before being installed on the precast concrete panel P. The upper open embedding nut 300b, The upper open embedding nut 300a or the through type embedding nut 300b is disposed in the formwork when the pre-cast concrete panel 300a or the penetration type embedding nut 300b is installed on the precast concrete panel P, When the concrete is poured and cured in the formwork and the form is removed, the upper open embedding nut 300a or the penetration type embedding nut 300b is embedded in the precast concrete panel P in a buried form.

That is, the upper open embedding nut 300a is located on the upper side of the precast concrete panel P and the lower side is closed.

In addition, the through type buried nuts 300b are buried so as to pass through the top and bottom of the precast concrete panel P.

The upper open embedding nut 300a and the penetration type embedding nut 300b can be used to perform functions such as loading, unloading, transporting, and height adjustment of the precast concrete panel P.

That is, a composite function capable of adjusting the height including the horizontal adjustment of the precast concrete panel P by using the upper open embedding nut 300a or the penetration type embedding nut 300b provided on the precast concrete panel P can do.
