Description

DRAIN BOARD FOR UNDER GROUND BASEMENT}

The present invention relates to a drainage plate for a basement floor, and more particularly, it is buried in the basement floor of a building or road to prevent condensation through noise prevention and ventilation as well as a drainage function. It can be connected, and in consideration of the subsequent concrete pouring process, it relates to a drainage plate for the basement floor in which the ventilation pipe mounted on the drainage plate can be used as a leveling bar.

In general, when excavation is performed in depth to construct an underground structure, the internal pressure of groundwater is lowered in the excavated layer, so that groundwater flows in from the surroundings, or condensation water penetrates into the basement floor due to moisture, and accordingly, the basement floor surface Condensation occurs in which moisture or groundwater forms.

When condensation, such as dew condensation, occurs on the surface of the basement deck layer, corrosion of the basement concrete layer is promoted, and an accident may occur due to slipping of vehicles or pedestrians.

In order to prevent this, when constructing basements and underground roads of various buildings, a drainage plate assembly that functions as a drainage between the foundation concrete layer and the concrete floor layer is installed.

That is, after the drainage plate assembly having a drainage passage is constructed on the foundation concrete layer, floor concrete of a predetermined thickness is poured thereon.

However, conventional drainage plate assemblies are basically provided in a structure having a drainage passage, but as they are manufactured in a structure with a large contact area with the base concrete layer, the drainage plate assembly becomes fine when a repeated load (vehicle, etc.) acts on the floor concrete layer. There is a problem that noise is generated at the contact portion between the drain plate assembly and the foundation concrete by moving and making frictional contact with the surface of the foundation concrete.

In addition, since the conventional drainage plate assembly is constructed in a sealed state between the base concrete layer and the floor concrete layer, there is a problem in that condensation such as water condensation on the surface of the floor concrete continues to occur.

As another embodiment for assembling the drainage plates 100 to each other, as shown in FIG. 8, a plurality of fitting projections 144 horizontally protruding outward are formed on two of the four sides of the drainage plate 100, and , In the other two sides, a coupling hole 154 into which the fitting protrusion 144 is inserted and fastened may be formed through, and by inserting the fitting protrusion 144 into the coupling hole 154, a plurality of drainage plates 100 They can be mutually assembled according to the construction area of the underground structure.

Here, looking at the construction process for the drainage and ventilation device of the present invention made of the above configuration is as follows.

6 shows a state in which a drain plate and a ventilation pipe for a basement floor according to an embodiment of the present invention are constructed between the foundation concrete and the floor concrete.

First, a slab-type foundation concrete 10 is poured on only the basement floor of a building or road.

Subsequently, the drain plate 100 manufactured in the above-described structure is continuously laid on the surface of the foundation concrete 10.

In more detail, while inserting and seating the coupling protrusion 140 formed on one drain plate 100 as described above into the coupling groove 150 formed on the other drain plate 100, the hook of the coupling protrusion 140 ( By inserting and fastening the 142 coupling groove 150 into the locking hole 152, the plurality of drainage plates 100 are mutually assembled to fit the construction area of the underground structure and are arranged on the surface of the foundation concrete 10.

At this time, when the drain plates 100 are assembled together as described above, the bottom surfaces of the first support groove 120 and the second support groove 130 of each drain plate 100 are closely supported on the surface of the foundation concrete 10. State.

Accordingly, between the first support groove 120 and the second support groove 130, and between the second support groove 130 at the bottom of the drain plate 100, a drainage space spaced apart from the surface of the foundation concrete 10 ( 132), when groundwater or the like penetrates over the foundation concrete 10, groundwater may be drained through the drainage space 132 to a collection well (not shown) at a predetermined location.

Subsequently, the operation of assembling the ventilation pipe 200 to the drain plate 100 is performed.

To this end, the lower end of the ventilation pipe 200 in which the ventilation hole 202 is formed is inserted into the ventilation space 112 through the center of the ventilation block 110 of the drain plate 100, and at the same time, the mounting end of the ventilation pipe 200 By allowing 204 to be mounted on the upper surface of the ventilation block 110, the ventilation pipe 200 is vertically erected on the drain plate 100 and is in an assembled state.

In addition, a ventilation cap 210 for communicating with outside air is fastened to the upper end of the ventilation pipe 200.

Accordingly, the ventilation space 112 in the ventilation block 110 of the drain plate 100 is in a state capable of communicating with the outside air by the ventilation pipe 200 and the ventilation cap 210.

Next, when the installation work of the drain plate 100 and the ventilation pipe 200 is completed, floor concrete 20 having a predetermined thickness is poured thereon.

Preferably, the ventilation pipe 200 is vertically erected on the drain plate 100, and the vertical erect length of the ventilation pipe 200 is a leveling function that starts the construction thickness of the floor concrete 20 Because it provides, it is possible to accurately construct the construction thickness of the concrete floor 20 according to the designed thickness.

At this time, based on the pouring of the floor concrete 20, the inside of the first support groove 120 in the shape of a square ring formed on the four circumferences of the ventilation block 110 of the drain plate 100 is filled with the floor concrete 20. At the same time, the bottom concrete 20 is also filled in the inside of the second support grooves 130 having a concave circular or polygonal shape formed on the four circumferential portions of the first support groove 120.

Accordingly, the bottom surfaces of the first support groove 120 and the second support groove 130 of the drain plate 100 are in close contact with the surface of the foundation concrete 10.

In this way, the first support groove 120 of the drain plate 100 is formed in a rectangular ring shape to minimize the contact area between the bottom surface and the foundation concrete 10, while at the same time minimizing the first support groove 120 and the second support. Since the drain plate 100 is stably supported and fixed by the floor concrete 20 filled in the groove 130, friction between the drain plate 100 and the foundation concrete 10 even if a repeated load acts on the floor concrete layer. It is possible to easily prevent the occurrence of noise.

In particular, the ventilation pipe 200 for preventing condensation is connected to the drain plate 100 installed between the foundation concrete 10 and the concrete floor 20, and the ventilation cap 210 fastened to the upper end of the ventilation pipe 200 is attached to the floor. By allowing the outside air on the surface of the concrete 20 to communicate with each other, the ventilation space 112 and the drain space 132 of the drain plate 100 spaced apart from the surface of the base concrete 10 are in a state in which the outside air is communicated, and ventilation is performed. Accordingly, it is possible to easily prevent the occurrence of condensation such as water condensation on the surface of the floor concrete 20.

On the other hand, in order to secure a larger internal volume space for ventilation between the foundation concrete 10 and the drain plate 100, the ventilation space 112 in the ventilation block 110 of the drain plate 100 is a drain space 132 It is desirable to communicate with.

To this end, as shown in FIG. 7, a plurality of convex upwards in order to communicate between the ventilation space 112 and the drain space 132 between the ventilation block 110 of the drain plate 100 and the first support groove 120 Four ventilation passages 114 may be further formed.

Accordingly, the drainage space 132 of the drainage plate 100 spaced apart from the surface of the foundation concrete 10 communicates with the ventilation space 112, and the ventilation space 112 communicates with the outside air by the ventilation pipe 200. As a result, the drainage space 132 is also in a state where it is easily communicated with the outside air, and condensation phenomenon such as water condensation on the surface of the floor concrete 20 can be more easily prevented from occurring.

On the other hand, the ventilation pipe 200 can be used as a level bar to guide the construction thickness of the floor concrete 20 by directly fastening it on the drain plate without inserting it into the drain plate 100.

To this end, as shown in FIG. 9, a ventilation pipe 200 having a length suitable for the construction thickness of the floor concrete at a predetermined position on the upper surface of the drain plate 100 is fixed with a piece as a level rod, and a level on the drain plate 100 The sealed ventilation pipe 200 is allowed to stand vertically.

Accordingly, the installer can see the ventilation pipe, which is a level seal standing vertically on the drain plate, and accurately construct the construction thickness of the floor concrete 20 according to the designed thickness.

As another embodiment for assembling the drain plate and the drain plate according to the present invention, it is possible to apply a combination of the two assembly structures so that the drain plate and the drain plate are not separated from each other and are firmly connected to each other.

That is, when the drain plate and the drain plate according to the present invention are mutually assembled, the two assembly structures may be combined and applied so that they are not separated from each other along the vertical and horizontal directions.

To this end, referring to FIGS. 10 and 11 showing another embodiment of an assembly structure between a drain plate and a drain plate for a basement floor according to the present invention, two of the four sides of the drain plate 100 are horizontal to the outside. The protruding fitting protrusion 144 and the fastening protrusion 146 protruding in the downward direction are formed together, and the fitting protrusion 144 is inserted into the other two sides so that the fitting protrusion 144 is inserted and fastened. A fastening hole 156 penetrating up and down so that 146 is inserted and fastened is formed together.

Therefore, the fitting protrusion 144 formed in one drain plate 100 is inserted into the coupling hole 154 in the other drain plate 100 in the horizontal direction, and at the same time, the fastening protrusion 146 formed in one drain plate 100 ) Is inserted into the fastening hole 156 in the other drain plate 100 in the vertical direction, so that the drain plate 100 and the drain plate 100 can be mutually assembled, and the drain plate and the drain plate are arranged in the vertical and horizontal directions. Accordingly, since they are not separated from each other, a solid assembly structure between the drain plates can be provided.

On the other hand, the drain plate 100 may be coated with an anti-pollution coating layer made of a composition for anti-pollution coating so as to effectively achieve the prevention and removal of contaminants.

The antifouling coating composition contains citrate and diethylene glycol monobutyl ether in a molar ratio of 1:0.01 to 1:2, and the total content of citrate and diethylene glycol monobutyl ether is 1 to 10 with respect to the total aqueous solution. It is weight percent.

The molar ratio of the citrate and diethylene glycol monobutyl ether is preferably 1:0.01 to 1:2, and if the molar ratio is out of the above range, the applicability of the drain plate 100 decreases or the surface moisture adsorption increases after application. Thus, there is a problem in that the coating film is removed.

The citrate and diethylene glycol monobutyl ether is preferably 1 to 10% by weight of the total aqueous solution of the composition, and if it is less than 1% by weight, there is a problem that the applicability of the drain plate 100 is deteriorated, and if it exceeds 10% by weight, it is applied. Crystal precipitation is liable to occur due to an increase in the film thickness.

On the other hand, as a method of applying the present antifouling coating composition to the drain plate 100, it is preferable to apply it by a spray method. In addition, the final coating film thickness of the drain plate 100 is preferably 700 to 2500 Å, more preferably 900 to 2000 Å. When the thickness of the coating film is less than 700 Å, there is a problem of deterioration in the case of high-temperature heat treatment, and when it exceeds 2500 Å, crystal precipitation on the coated surface is liable to occur.

In addition, the present antifouling coating composition may be prepared by adding 0.1 mol of citrate and 0.05 mol of diethylene glycol monobutyl ether to 1000 ml of distilled water, followed by stirring.

The reason why the ratio of the constituent components and the coating film thickness were numerically limited as described above is that the present inventors analyzed through the test results while repeatedly failing several times, and as a result, the optimum anti-fouling coating effect was exhibited at the ratio.

In addition, the ventilation pipe 200 and the ventilation cap 210 may be coated with a fragrance material mixed with a functional oil that is useful for sterilization and stress relief of workers.

The mixing ratio of the perfume material and the functional oil is 95 to 97% by weight of the perfume material and 3 to 5% by weight of the functional oil is mixed, and the functional oil is 50% by weight of Allspice oil and Elemi oil. ) It consists of 50% by weight.

Here, it is preferable that 3 to 5% by weight of the functional oil is mixed with respect to the fragrance material. When the mixing ratio of the functional oil is less than 3% by weight, the effect is insignificant, and when the mixing ratio of the functional oil exceeds 3 to 5% by weight, the effect is not greatly improved, while the manufacturing cost is greatly increased.

Allspice oil has good antibacterial, sterilization, and stress relief effects.

Elemi oil has an excellent effect on sterilizing, clearing the head, and healing tension.

Therefore, as the perfume material mixed with such a functional oil is coated on the ventilation pipe 200 and the ventilation cap 210, the ventilation pipe 200 and the ventilation cap 210 are sterilized and the fatigue of the worker You can get the effect.

The reason for limiting the constituents and limiting the numerical value of the mixing ratio for the perfume substance and the functional oil is that the present inventors have repeatedly failed several times and analyzed through the test results, as a result of the optimal effect in the above constituents and numerically limited ratios. Is shown.
