Description

Drainage Trench Unit

(Technology)

The present invention relates to a drain trench unit, and more particularly, to a drain trench unit of concrete that is built in the parking lot floor or the like to form a drain trench.

(Background)

Floors for which wastewater has to be treated in use, such as indoor parking lot floors, are typically built with drainage trenches to collect and discharge the wastewater to sewage. In installing such drainage trenches, it was common to build drainage trenches on-site by directly stacking bricks when placing floor concrete.

3 is a schematic longitudinal cross-sectional view of a drainage trench built on site when placing floor concrete; The construction of the conventional drainage trench 100 shown in FIG. 1 first forms a trench installation groove 110 having a sufficient width at a position where the drainage trench 100 is to be constructed by using the formwork when pouring the first floor concrete BC1. Next, the angle 120 is supported in parallel on the upper sides of the trench installation grooves 110, and the bricks 130 are stacked and blocked thereunder, and then the secondary bottom concrete BC2 is disposed up to the angle 120. Is poured to have a slope toward the drainage path 100, and finally, after waterproofing the inner surface of the drain trench 100, the mortar (M) is given to the bottom of the drainage path 100 to have a gradient toward the sump. After applying, the glazing 140 is finally raised on the angle 120 to be completed.

The drainage trench 100 of the field construction method as described above is complicated and difficult to work, such as installing the angle 120, stacking bricks 130, and matching the gradient of the entire drainage trench 100. There is a problem of low productivity. In particular, since it is not easy to adjust the thickness of the mortar (M) for the overall drain trench 100 to match the gradient to the sump well, there are many cases where a reverse gradient occurs and smooth drainage does not occur. When the angle 120 and the glazing 140 and the adjacent glazing 140 collide with each other, the noise is also very severe.

In order to solve the problems of the drainage trench 100 of the field construction method, a drainage trench unit having a predetermined length is manufactured as a ready-made product in a factory, not a construction site, and then the drainage trench is constructed by assembling and constructing it at the construction site. Technology is developed.

Figure 4 is an exploded perspective view of the 'drainage passage mold' of Utility Model Publication No. 97-5532 showing an example of a conventional drain trench unit. The conventional drainage mold 200 has a plurality of side members 210 having a cover support portion 211 and an insertion groove 212 and a bottom member 220 having an insertion protrusion 221 to assemble a plurality of parts. Using the piece 231 has a structure to be fixed to the floor by the mold support member 230.

However, although the drainage formwork 200 has eliminated the inconvenience of having to build the drainage trench directly at the construction site, the number of parts and the assembly work are complicated, and still require a lot of work time. Due to the difference in thermal expansion coefficient between the drainage mold 200 and the floor concrete, there is a problem that the drainage mold 200 is easily lifted from the floor according to the temperature change.

Due to such a problem, the conventional drainage path mold 200 is not actually applied to the site, and the drainage trench 100 of the complex traditional site construction method as shown in FIG. 3 is still used.

The purpose of the present invention is to solve the problems of the conventional field construction drainage trench or prefabricated drainage trench unit built on the floor of an indoor parking lot, and the construction work in the field is very simple and easy to match the draft. It is to provide a durable drain trench unit.

Another object of the present invention is to provide a drain trench unit having a structure capable of reducing noise generated when a vehicle passes through as a drain trench unit built in a floor of an indoor parking lot or the like.

The Trenz body is made of concrete and has a bottom portion and both side portions so as to form a drainage passage having a predetermined width, height and length, and has a shape of upper and lower beams in which the outer surface of each side portion is widened toward the lower side. The upper surface of each side part forms a horizontal plane. Preferably at least the bottom surface of the bottom portion to form an unevenness can improve the bonding strength with the concrete poured on the floor.

The buffer plate is coated and bonded to the upper surface of the trench body, respectively, and absorbs contact noise with the glazing mounted thereon.

The grating insertion guide is preferably composed of two angle bars (L-shaped steels) having a vertical surface and a horizontal surface, and the vertical surface is parallel to the trench body so that the vertical surface is spaced apart from the drainage by a predetermined distance. It is fixed and the horizontal surface is embedded in the floor concrete.

The glazing is inserted between the glazing inserting guides, and a plurality of cushioning pieces are mounted on at least one side of the vertical surface of the glazing inserting guide and the circumferential surface of the glazing so that the glazing inserting guide and the glazing and the It is desirable to absorb contact noises between the gratings.

Hereinafter, the drainage trench unit according to the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are merely illustrative of the drainage trench unit according to the present invention, and are not intended to limit the scope of the present invention.

1 is a perspective view of an exemplary drainage trench unit according to the present invention, and FIG. 2 is a cross-sectional view of the drainage trench unit of FIG.

As shown, the drain trench unit 1 according to the present invention, the trench body 10 of the concrete 11, the drainage path 13 is formed, the buffer plate 20 bonded to the upper side of the trench body 10 ), And a glazing inserting guide 30 fixed to the trench body 10 on the buffer plate 20 and a glazing 40 inserted between the glazing inserting guide 30 as a basic unit. It is.

The Trenz body 10 is made of concrete 11, and the bottom 14 of the horizontal and vertical so as to form a drainage passage 13 of a predetermined width (W), height (T) and length (L) therein Both side portions 15 are provided. Concrete 11 to be used is a waterproof treatment to prevent leakage and the reinforcement wire 12 is preferably put inside.

The waterproofing may use a known waterproofing method such as adding an appropriate waterproofing liquid, for example, when making a concrete mixture for manufacturing the trench body 10. The reinforcing wire 12 is for reinforcing the strength of the concrete 11, for example, when the trench body 10 is made of concrete 11, a wire mesh made by weaving a wire mesh of 5 mm diameter in a lattice shape is formed at the bottom ( 14) and both sides 15. In the concrete 11, it is preferable to mix fine aggregate (for example, a stone of about 10 mm in diameter) for reinforcement.

Thus, since the trench body 10 is made of concrete 11 such as concrete (or mortar: C) that is poured on the floor F, when the trench body 10 is constructed on the floor F, the trench body ( 10) and the bottom concrete (C) is a perfect joint, virtually no cracking or warping occurs.

The size of the drainage path 13 formed in the trench body 10 is determined according to the characteristics of the place where the trench unit 1 of the present invention is constructed, and the illustrated embodiment is about 140MM-for the floor F of the underground parking lot. It shows an example in which a drainage path 13 having a width W of 200M and a height T of 40MM-70MM is formed. In addition, the length L of the trench body 10 may be approximately 1,000MM (1M) in consideration of the convenience of transportation, handling, and construction.

Both side surface portions 15 of the trench body 10 have a shape of upper and lower light, and the upper surface 18 of each side surface portion 15 forms a horizontal plane having a predetermined width (for example, 50 mm). In the example shown, the side portion 15 of the trench body 10 gradually widens as its outer surface 16 goes downward, and its inner surface 17 is approximately vertical (92 in the illustrated embodiment), The upper surface 18 is a horizontal plane. The side surface portion 15 of the trench body 10 is formed in the upper and lower light in order to maintain the trench body 10 firmly in the concrete C of the floor F.

The bottom surface of the bottom portion 14 of the trench body 10 in contact with the concrete (C) to be poured on the floor (F) is preferably formed with irregularities 19, respectively, in order to improve the bonding force with the bottom concrete (C). The trench body 10 is more firmly fixed to the bottom F by the action of the unevennesses 19. Such unevenness 19 may also be formed on the outer surface 16 of the side portion 15.

In addition, the surface of the drainage passage 13 is made of a film 50 such as plastic resin to prevent the bottom concrete C from falling down and hardening in the drainage passage 13 of the trench body 10 during the finishing process of the bottom F. It is desirable to tap and ship the product so that it can be removed after construction is complete.

The buffer plate 20 is coated and bonded to both upper surfaces 18 of the Trenz main body 10. The buffer plate 20 is for absorbing the contact noise between the concrete 11 of the trench body 10 and the glazing 40 mounted thereon, preferably made of a rigid rubber plate, the thickness of about 2.5MM This is enough. Bonding of the buffer plate 20 to the trench body 10 may be carried out by molding and hardening the buffer plate 20 by contacting the upper surface 18 on both sides when forming the trench body 10 with concrete 11. In addition, the shock absorbing plate 20 is fixed so as not to be separated from the trench body 10 by the fastening piece 34 which fixes the grating insertion guide 30 which will be described later. The action of the shock absorbing plate 20 can completely prevent the noise generated by the glazing 40 hitting the concrete 11 of the Trenz body 10 when the vehicle passes over the glazing 40.

The grating insertion guide 30 is fixed to both upper surfaces 18 of the trench body 10, that is, the buffer plate 20. The grating insert guide 30 is composed of two bar members made of steel having a vertical surface 31 and a horizontal surface 32, preferably two galvanized angle bars 30A of approximately 30MM × 30MM × 1,000MM. L-shaped steel) can be used.

The vertical surfaces 31 of the two angle bars 30A of the grating insertion guide 30 have, for example, a horizontal surface 32 at a position spaced a predetermined distance (for example, 30 mm) from both ends of the upper side of the drainage passage 13. It is fixed to the Trenz body 10 in parallel on the buffer plate 20 in a state facing away from the drainage channel (13). The fixing of the angle bar 30A can be fixed by fastening the fastening piece 34 (for example, Calvlock) to the hole 33 drilled in the horizontal plane 32 at predetermined intervals (for example, 300 mm interval). As described above, the shock absorbing plate 20 is firmly fixed to both upper surfaces 18 of the Trenz main body 10 by fixing the grating insertion guide 30 by the fastening piece 34. In addition, the concrete (C) of the floor (F) is poured to the top of the vertical surface 31, the horizontal surface 32 is completely embedded in the floor concrete (C).

In the illustrated embodiment, the trench body is 50MM with the vertical surface 31 of the angle bar 30A of 30MM spaced apart 30MM from both ends of the upper side of the drainage channel 13 with the horizontal surface 32 facing away from the drainage channel 13. By being fixed on the top surface 18 of (10), about 10MM of the horizontal surface 32 protrudes out of the top surface 18 of the main body 10 and is buried into the bottom concrete (C), and thus for the bottom concrete (C). The fixing of the grating insertion guide 30 is more firm.

The glazing 40 is inserted into the glazing insertion guide 30. The present glazing 40 may use conventional glazing widely used in drainage trenches. Since the glazing insertion guide 30 and the glazing 40 are both made of metal and there may be a slight gap between the glazing insertion guide 30 and the glazing 40 and between the adjacent glazing 40. When the vehicle passes, the glazing insertion guide 30 and the glazing 40 and the adjacent glazing 40 collide with each other, and noise may occur.

In order to remove such noise, a plurality of holes 35 and 42 are drilled on at least one side of the vertical surface 31 of the glazing insertion guide 30 and the circumferential surface of the glazing 40 to provide a cushioning piece such as an elastic rubber ( It is preferable to insert and insert 41). According to such a cushioning piece 41, it is possible to completely block the noise due to the impact of the glazing insertion guide 30 and the glazing 40 and the adjacent glazing 40.

The drainage trench unit 1 according to the present invention described above, in a large fabrication of the trench body 10 in the state in which the buffer plate 20 is bonded by using a mold in a fabrication shop such as a brick factory according to the standard After attaching the rating insertion guide 30 is supplied to the construction site with the glazing 40.

Hereinafter, a method of constructing the drain trench unit 1 according to the present invention on the floor F will be described.

First, the concrete (C) is laid on the floor (F) at the position where the drainage trench unit 1 is to be installed, and the trench body 10 provided with the buffer plate 20 and the grating insertion guide 30 is placed thereon. At this time, when the bottom concrete (C) is poured, the bottom concrete (C) is poured to have a gradient toward the sump, and the trench body 10 is placed on the bottom concrete (C) to incline the length of each trench body 10. By slightly adjusting, the top of the vertical surface 31 of the grating insertion guide 30 approximately coincides with the bottom finish line, while fitting the gradient of the entire drain trench.

Next, a well-known silicone sealant is coated on the connection portion of the adjacent trench body 10 to waterproof the connection portion.

Subsequently, the bottom concrete C is poured to the upper end of the vertical surface 31 of the grating insertion guide 30 so that the horizontal surface 32 is embedded in the bottom concrete C. At this time, the bottom (F) is finished at the top height of the vertical surface 31, it is preferable to put a slight gradient toward the drainage passage 13 so that the sewage of the bottom (F) can flow smoothly into the drainage passage (13).

Finally, after the entire drainage trench construction by the drain trench unit 1 and the finishing of the bottom F are completed, the tape 50 is peeled off on the surface of the drainage passage 13 to the surface of the drainage passage 13 during construction. Remove any lumps of concrete (C) that were dropped.

In addition, in the part where the drain trench unit 1 of unit length (1,000 mm) cannot be used as it is, such as a corner part, the drain trench unit 1 is appropriately cut and used according to the size of the corresponding part. For this purpose, accessories such as L-shaped attachments for corners, T-shaped attachments for branch points, and cross-shaped attachments for intersections may be appropriately manufactured and used in accordance with the characteristics of the present invention.

According to the drainage trench unit 1 according to the present invention described above, it is possible to build the entire drainage trench simply by connecting the drainage trench units 1 continuously at the construction position of the drainage trench and constructing the finishing floor. Therefore, the construction work is very simple and consequently the construction cost can be reduced.

In addition, the drain trench unit 1 according to the present invention adjusts the slope of the entire drain trench simply by raising the drain trench units 1 on the floor concrete F poured to have a gradient and adjusting a slight slope. It is very easy to fit the gradient.

In addition, in the drain trench unit 1 according to the present invention, the trench body 10 is made of concrete, and both side portions 15 of the trench body 10 are in the shape of upper and lower light, and additionally, the bottom portion 14 Since the unevenness | corrugation 19 is formed in the bottom face, the drainage trench unit 1 is firmly fixed to the floor concrete C, and it does not easily lift or cause a crack even in the load of a vehicle.

In addition, the glazing insertion guide 30 of the drain trench unit 1 according to the present invention, the horizontal surface 32 is fixed to the trench body 10 by the fastening piece 34 as well as the bottom concrete (C) By embedding in the glazing 40 can be maintained very firmly.

In addition, the glazing 40 is raised through the buffer plate 20 between the trench body 10 made of concrete 11, and the glazing insertion guide 30 and the glazing 40 and the adjacent glazing ( The cushioning piece 41 is interposed between the glazing 40 and the trench body 10, the glazing insertion guide 30 and the glazing 40, and the adjacent glazing 40 as the vehicle passes through. This can prevent noise that may be generated by bumping.
