Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage system,

The present invention relates to a drainage installation facility and a drainage installation method.

On the bottom of the roof of the structure (building), the underground parking lot, the machine room, and the electric room, a trench for collecting rainwater, cleaning water and inflow water (hereinafter referred to as "water") is drained.

In order to construct a drainage channel, a metal-made angle that holds the width and height of a trench (hereinafter referred to as drainage) is provided on the bottom of the structure (hereinafter referred to as foundation layer). The angle has a predetermined length, and the upper surface is separated from the foundation layer by the thickness of the free-flowing concrete (hereinafter referred to as concrete) and is supported by the supporting member.

After installing the angle, install plywood formwork, cement brick, libra, etc. on the side, then pour the concrete up to the top of the angle and remove the mold when cured. After removing the formwork, the sides and bottom of the drainage channel are closed with cement mortar and at the same time a bottom draft work is carried out to smooth the flow of water.

In the above drainage construction, the air is lengthened by various processes such as angle installation, formwork installation (brick blocking, libra cracking), concrete pouring, demolition of the formwork, drainage side and floor finish plastering, This took considerable time.

When the concrete is not completely filled in the lower part of the angle, there is a situation where the angle is sagged, and the exposed surface of the angle is processed properly. If it is not used, it causes corrosion easily because it is a place to use water, and due to increase in volume due to corrosion, the finish part is broken and the appearance is deteriorated. This has the inconvenience of carrying out additional maintenance work.

And if the draft of the drainage channel is not formed precisely, the flow of water is not smooth, and the water in the drainage line becomes corrupt, and odor is generated

The depth of the drainage channel is determined by the thickness of the floor formed on the foundation layer, and the length is determined by the width of the floor. If the floor width is relatively wide, the length of the drainage channel should also be prolonged. It is difficult for an operator to make a gradient of a long drain within a certain thickness of the floor, and the gradient can not be accurately made.

If the floor slope is caught by the mortar, it will be peeled off if it is not adhered properly. If the water is not drained smoothly on the roof, it will penetrate into the mortar.

Published Japanese Patent Application No. 10-2001-0044805 (Jun. 2001)

The present invention provides a construction facility and a drainage installation method that simplify the drainage installation process and prevent defects after installation.

A drainage installation apparatus according to an embodiment of the present invention includes a supporter, a support unit coupled to the supporter, a bottom member and side wall members connected to both ends of the bottom member, Wherein the bottom member is inclined with respect to the upper surface of the side wall member and the concrete pouring on the bottom surface of the bottom member is formed by the inclined bottom surface of the bottom member.

The supporter includes a base member that can be fixed to the base layer, a level adjusting member vertically connected to the base and passing through the supporting portion, first and second stoppers coupled to the level adjusting member via the supporting portion, And the distance between the base layer and the support portion may be adjusted according to the positions of the first and second stoppers.

Wherein the support comprises a horizontal bar located below the bottom member and connected to the supporter and adjustable in position, a vertical bar vertically connected to the horizontal bar and spaced apart from the sidewall, The side wall member may include a through hole through which the coupling member passes, and the projection member may be formed with a coupling hole to which the coupling member is coupled.

A drainage installation apparatus according to another embodiment of the present invention includes a supporter, a supporter coupled to the supporter so as to be adjustable up and down, and a mold connected to the supporter, wherein the mold is separated from the supporter And the supporter and the supporting portion are embedded in the concrete after the installation with the drainage, and are not exposed.

The depth from the top surface to the bottom of the mold can vary along the length direction.

The height of the mold frame may be higher than the height of the support portion with respect to the base layer on which the supporter is fixed.

A method of constructing a drainage system according to an embodiment of the present invention includes the steps of (S10) installing a supporter on a foundation layer of a structure to form a floor, (S20) connecting a supporter to the supporter, (S30) (S40) placing a concrete on the base layer to the upper surface of the mold, and (S50) separating the mold from the support by separating the engaging member, In step S40, the concrete is poured between the mold and the support. If the mold is removed in step S50, the support is not exposed to the outside of the poured mortar.

When the coupling member and the mold frame are separated from each other, the periphery of the coupling hole formed in the support portion and coupled with the coupling member is exposed, and the drain hole construction method may further include a finishing step of filling the coupling hole of the support portion .

In the step (S30), the height of the mold frame may be higher than the height of the support part with respect to the base layer.

In the step (S30), a spacer may be provided in the mold.

According to the embodiment of the present invention, the bottom member is inclined with respect to the upper surface of the side wall member, and the bottom is also inclined (drafted) by the drain formed by the bottom member. The draft can be made correct by taking the slope of the bottom of the drain by the mold.

According to the embodiment of the present invention, the construction equipment can be installed with drainage by joining the formwork to the support part provided on the foundation layer, and the drainage can be formed by the formwork. Even if the mold frame is separated, the drainage channel is formed smoothly. Thus, since the angle installation, the side finishing, and the bottom draft finishing process do not occur as in the conventional art, the air can be minimized and the construction cost can be reduced.

According to the embodiment of the present invention, the separated molds can be reused and are economical. Therefore, waste can be minimized and environmental problems due to waste treatment can be prevented.

According to the embodiment of the present invention, since the drainage installation facility is produced in the factory, it is easy to use, and drainage installation can be easily performed. Therefore, it is possible to easily construct a drainage facility even if a specialist is not an expert in drainage construction.

According to the embodiment of the present invention, the floor and the side surface are connected to the curved surface by the shape of the mold, so that the flow of water and cleaning can be easily performed, so that the odor generated due to the sticking of water can be prevented in advance.

According to the embodiment of the present invention, a drainage channel is formed by a mold frame, and the upper portion of the side wall is formed obliquely so as to prevent breakage of corners or the like. Therefore, the maintenance work according to the use does not occur.

According to an embodiment of the present invention, a drainage channel can be formed without installing an angle by using a drainage installation facility. Therefore, it is possible to fundamentally prevent problems such as angles occurring due to the use of angles, gaps occurring between the bottoms and angle corrosion, and the like, thereby improving the reliability of the drainage channel.

Like parts are designated with like reference numerals throughout the specification.

A drainage installation system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG.

FIG. 1 is a perspective view showing a drainage installation apparatus according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of FIG. 1, FIG. 3 is a sectional view taken along the line III- Fig.

1 to 4, a drainage installation apparatus 100 according to the present embodiment includes a support 110, a support 120, a mold 130, a coupling member 140, and a spacer 150.

The supporter 110 is arranged on the base layer 300 to adjust the height of the support portion 120 and includes a base member 111, a level regulating member 112, a first stopper 113 and a second stopper 114, .

The base member 111 has a predetermined width and is fixed to the base layer 300. The base member 111 is fixed in a different manner depending on the structure of the base layer.

For example, when the base layer 300 does not have a waterproof layer, the base member 111 is fixed to the nail 111a or the anchor bolt 111b. The nail 111a is fixed to the base layer through the hole formed in the base member 111 (see Fig. 5 (a)). The anchor bolts 111b are fixed to the base layer in contact with the edge of the base member 111 and the anchor bolts 111b and the base member 111 are joined to each other by welding or the like (Figure 5 (b) Reference). However, when the waterproof layer is formed on the foundation layer, the base member 111 is fixed to the mortar 111c so as not to damage the waterproof layer (see FIG.

The level regulating member 112 protrudes vertically from the center of the base member 111 and has a predetermined length, and a screw is formed on the outer circumferential surface.

The mortar 111c does not exceed the level adjusting member 112 when the base member 111 is fixed with the mortar. The upper side of the level regulating member 112 is exposed to the outside of the mortar (see Fig. 5 (c)).

The first stopper 113 and the second stopper 114 are formed in a nut structure, and are spaced from each other in the level adjusting member 112 and are sequentially coupled in the vertical direction. The first stopper 113 is first engaged and the support 120 is coupled to the level regulating member 112 and then the second stopper 114 is coupled to the level regulating member 112. [ The positions of the first stopper 113 and the second stopper 114 can be changed according to the thickness T (see FIG. 12) of the bottom 400 (see FIG. 12).

The supporter 120 includes a horizontal bar 121, a vertical bar 122, a protrusion member 123 and a coupling member 140 which are coupled to each of the supporters 110 arranged to support the mold 130.

The horizontal bar 121 has a predetermined length and a level hole 121a through which the level adjusting member 112 passes is formed on one side and the other side. The diameter of the level hole 121a is larger than the diameter of the level adjusting member 112. [

The horizontal bar 121 is coupled to the level adjusting member 112 and placed on the first stopper 113 in a state where only the first stopper 113 is coupled to the level adjusting member 112. The second stopper 114 is coupled to the level adjusting member 112 to fix the horizontal bar 121.

The vertical bars 122 are formed as a pair and face each other at intervals. The vertical bar 122 is vertically coupled to the center of the horizontal bar 121 at a portion of the horizontal bar 121 where the level hole 121a is formed. The connected portion of the vertical bar 122 and the horizontal bar 121 is formed as a curved surface or an inclined surface. The vertical bar 122 and the horizontal bar 121 may be integrally molded or welded together during manufacture. However, the vertical bar 122 and the horizontal bar 121 may be detachably coupled through the projection and the projection groove (not shown).

The protruding members 123 protrude vertically toward the center S of the horizontal bar 121 on the opposed surfaces of the vertical bar 122. The projection member 123 is provided with a coupling hole 123a having a screw. A coupling member 140 for fixing the mold 130 to the support 120 is fastened to the coupling hole 123a.

When concrete or mortar is placed on the foundation layer 300 to form the floor, the support 120 is not exposed to the outside of the cured concrete or mortar.

The support 120 may be made of polyvinyl chloride (PVC). However, the support 120 and the supporter 110 may be made of metal for the required bearing capacity.

The mold 130 has a predetermined length and forms a drain. The mold 130 includes a bottom member 131 and a side wall member 132. The bottom member 131 and the side wall member 132 are integrally formed.

The bottom member 131 forms the bottom 210 (see FIG. 13) of the drainage passage 200 and the side wall member 132 forms the side wall 220 (see FIG. 13) of the drainage passage 200. The sidewall members 132 are spaced apart. The bottom member 131 connects the lower side of the side wall member 132 to each other. The bottom member 131 and the side wall member 132 are curved. Thus, the bottom and side of the drain can be connected in a curved shape. The spacing of the side wall members 132 may be 100 mm, 150 mm, 200 mm. The width of the bottom member 131 is determined according to the distance between the side wall members 132. [ The width of the drainage channel is determined by the spacing of the side wall members 132.

The bottom member 131 has the same width, and the height of the side wall member 132 is changed along the longitudinal direction. So that the bottom member 131 may gradually move away from or close to the top of the side wall member 132 along the longitudinal direction. Thus, the bottom member 131 is inclined with respect to the upper surface of the side wall member 132.

On the upper side of the side wall member 132, a through hole 133 through which the coupling member 140 passes is formed with a space therebetween along the longitudinal direction. The distance between adjacent through-holes 133 may be between 450 mm and 500 mm.

The mold 130 may be made of polyvinyl chloride (PVC), aluminum, iron, or the like. The present invention is not limited to the material of the mold 130.

On the other hand, the side wall member 132 is inclined outwardly. Here, the sidewall member 132 may be divided into a first portion 132a and a second portion 132b. The inclination of the second portion 132b is larger than the inclination of the first portion 132a. However, the first portion 132a may be skewed and the second portion 132b may be inclined. The inclination of the side wall member 132 may be such that the entire side wall member 132 is inclined or only the outer side thereof is inclined.

On the other hand, the mold 130 can be easily separated from the cured concrete, and the exfoliating agent can be applied to the outer surface of the mold 130 so as not to damage the concrete upon separation. The release agent is generally used in a construction site and will not be described in detail below.

The spacer 150 has a predetermined length and is positioned between the side wall members 132 and is coupled to the coupling member 140 at both ends. Both ends of the spacer 150 are coupled to each other in such a manner as to span the coupling member 140. The spacers 150 allow the sidewall member 132 to maintain a predetermined spacing uniformly. The sidewall member 132 may also be pressurized when the concrete is poured. At this time, the spacer 150 supports the pressure so that the side wall member 132 is not bent inward. However, the spacers 150 may be omitted.

Next, a method of constructing a drainage channel will be described with reference to Figs. 6 to 12. Fig.

FIG. 6 is a block diagram of a drainage installation method according to an embodiment of the present invention, and FIGS. 7 to 13 are drainage installation process drawings.

6 to 13, the drainage installation method according to the present embodiment includes the steps of installing a supporter S10, attaching a support portion S20, attaching a mold frame S30, placing a concrete S40, S50) and a finishing step (S60).

The foundation layer (300) of the structure forming the floor is assembled before the drainage channel is constructed. When the base layer 300 is assembled, the supporters 110 are arranged at a position where the drainage passage is to be formed. The supporters 110 are arranged in one direction in two groups. The base member 111 is fixed to the base layer 300 while being in close contact with the base layer. The supporter 110 is fixed in various ways to the nail 111a, the anchor bolt 111b and the mortar 111c according to the structure of the foundation layer 300 as shown in Fig. The first stopper 113 is engaged with the level adjusting member 112 (see Fig. 7).

The position of the first stopper 113 depends on the thickness of the bottom 400.

The support portion 120 is coupled between the pair of supporters 110. The level bar 121a is used to couple the horizontal bar 121 to the level adjusting member 112. The second stopper 114 is coupled to the level adjusting member 112 to fix the supporting portion 120 to the supporter 110 (S20) (see FIG. 8).

The mold 130 having the outer surface coated with the releasing agent is placed between the vertical bars 122 and the through hole 133 and the engaging hole 123a are aligned with each other. The engaging member 140 that penetrates the through hole 133 is fastened to the engaging hole 123a and the mold 130 is coupled to the supporting portion 120. [ The protrusion member 123 is brought into contact with the outer surface of the mold 130 so that the vertical bar 122 and the horizontal bar 121 are spaced from the outer surface of the mold 130. Since the bottom member is inclined with respect to the upper surface of the side wall member and the through holes 133 are positioned on the same line, the form 130 is tilted from one side to the other side (S30) 3 and Fig. 9).

The spacers 150 are coupled between the side wall members 132 to support the side wall members 132. The spacer 150 is joined in the form of spanning the engagement member 140 (see FIG. 10). However, the coupling of the spacer 150 may be omitted

The supporter 110 is fixed to the base layer and the supporter 120 is coupled to the supporter 110 and the mold 130 is coupled to the supporter 120. However, The supporting part 120 and the mold frame 130 are assembled in a manufacturing factory and can be installed directly on the construction site. In this case, installation time of the construction equipment 100 can be minimized by discharging drainage water, which can shorten the air.

When the drainage installation apparatus 100 is installed in the foundation layer 300, concrete or mortar is installed in the foundation layer 300. Hereinafter, it is assumed that concrete is installed in this embodiment. The base layer 300 is poured in the state of no reinforcing bars. However, a wire mesh (not shown), a reinforcing bar (not shown), or the like may be disposed on the base layer 300 according to the structure of the structure. The concrete to be laid is poured from the foundation layer 300 to the upper surface of the mold 130 and poured between the mold 130 and the support 120 without voids (S40) (see FIG. 11). Concrete laid on the bottom surface of the bottom member 131 is sloped by the inclined bottom surface of the bottom member 131.

When the concrete is cured, a floor 400 is formed on the foundation layer 300. The spacer 150, the engaging member 140, and the mold frame 130 are separated from each other (S50) (see Fig. 12 (a)). Since the exfoliating agent is applied to the outer surface of the mold 130, the mold 130 can be separated without damaging the concrete.

A drainage duct 200 in the form of a mold 130 is formed on the floor 400 by the mold 130 separation. The connecting portion of the bottom 210 and the side wall 220 is formed in a smooth curved shape. The sidewall 220 of the drainage channel 200 is also inclined according to the inclination of the side wall member 132. The portion C where the side wall 220 and the surface of the bottom 400 are connected by the second portion 132b of the side wall member 132 is in a tilted state (see Fig. 12 (a)).

The bottom 210 of the drainage channel 200 is tilted from one side to the other by the inclination of the bottom member 131 (see Fig. 12 (b) (section cut in the longitudinal direction of the drainage channel) The water can flow without being accumulated in the drainage passage 200. [

Since the concrete to be laid is also placed between the mold 130 and the support 120, when the mold 130 is removed, the support 120 is buried in the floor 400. [ The support 120 is not exposed to the drainage passage 200. However, since the mold 130 and the protrusion 123 contact with each other, the protrusion 123 contacting the mold 130 is exposed to the drain 200. In this case, since the peripheral portion of the coupling hole 123a is visible, the aesthetic appearance is hindered, and water may flow into the coupling hole 123a and the water may be corroded, resulting in malodorous or the like. Silicon or the like for waterproofing is injected into the coupling hole 123a and the bolt B is engaged to fill the coupling hole 123a (S60) (see FIG. 13). Bolt (B) can be a round head bolt. Filling the fitting hole 123a is not limited to a bolt. However, the process of filling the coupling hole 123a may be omitted.

Accordingly, the present invention can minimize the air flow and reduce the construction cost by avoiding the conventional processes such as angle installation and finishing.

The bottom 210 of the drainage passage 200 is formed in an inclined shape by a mold 130 coupled with the support 120. The process of drafting the bottom 210 of the drainage duct 200 after the separation of the mold 130 does not occur. And the draft can be corrected by taking the draft by the mold.

Since the mold 130 can be reused after being separated from the mold 130, it is possible to minimize the generation of waste, which is economical and can prevent environmental problems due to waste treatment.

Because drainage construction equipment is produced at the factory, it is easy to use because it is elaborate and easy to use. Therefore, it is possible to easily construct drainage even for non-experts, without specialists on drainage works.

Since the mold frame 130 is formed to have a length of 6000 mm, a drainage duct of 12000 mm can be formed when the drainage installation apparatus 100 is positioned on both sides with respect to the drainage hole H. The shape of the mold 130 allows the drainage channel 200 to be inclined toward the drainage port, so that the water can be drained to the drainage port without being accumulated in the drainage channel (see FIG. 14).

The shape of the mold 130 allows the bottom and sides of the drainage water to be connected to the curved surface to facilitate the flow of water and cleaning, thereby preventing odors generated due to decay of the water.

A drainage channel is formed by the mold 130 and slopes are formed at a portion connected to the side wall and the bottom surface of the drainage water so that the edges generated when the side walls 220 and the bottom surface 400 are connected at right angles do not occur. Therefore, the maintenance work according to the use does not occur.

If drainage construction equipment is used, drainage can be formed without installing angle. Therefore, it is possible to prevent problems such as occurrence of gaps and angle corrosion between the angle generated by using the angle and the bottom, and reliability of the drain can be improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Of the right.
