The present invention relates to a composite material fixing apparatus for a drain pipe, and more particularly, to a composite material fixing apparatus for a lightweight and interior-improved drain pipe for an ambient environment.

Generally, a drainpipe is installed to discharge rainwater or wastewater to the outside of the structure. Particularly, bridges formed so as to allow passengers, vehicles, etc. to pass through rivers, canals, lowlands, valleys, and the like are continuously installed along the longitudinal direction of the bridges.

In detail, the bridge comprises a top plate, a barrier wall formed at the edge of the top plate to prevent fall, and a bridge supporting the top plate. At this time, the top plate or the barrier wall is provided with a drainage system for draining the road surface water such as rainwater or sewage.

Here, the drainage system is divided into a point drainage system in which a collection port at which the inflow and drainage of road surface water are concurrently formed at regular intervals, and an upstream water supply system in which an inlet is formed as a whole along the longitudinal direction of the bridge and an outlet is formed at intervals .

At this time, the pre-existing water system includes a plurality of the lateral water pipes which penetrate the barrier wall in the width direction and discharge the road surface water collected on the top plate to the outside of the bridge, And a drain pipe connected to the drain pipe along a longitudinal direction of the drain pipe.

At this time, in order to install the drain pipe along the longitudinal direction of the bridge, a fixing means made of a metal material has been used. Specifically, the fixing means includes a fixing bracket fixed to a side surface of the bridge, and an extension bar extending to one side of the fixing bracket and engaged with an upper end of the line water pipe.

However, in the case of the fixing means made of the conventional metal material, the snow removers, which are corroded by rain or snow, or sprayed on the road surface for snow removal, are mixed with the road surface water, .

This causes a problem that the durability of the drainage system is deteriorated by corroding the fastening means, the fixing means and the fastening portion to the drainage pipe. As a result, the load on the road surface or the impact transmitted from the bridge can damage the fastening portions of the fixing means, the fixing means, and the drain pipe.

As a result, there is a problem in that the repair and replacement of the broken fastening means are costly and manpower consumed and economic efficiency is lowered. In addition, there has been a problem in that the surrounding of the fixing means is broken as described above, and the water pipe falls down to a facility provided below the bridge, or a person traveling on the lower side of the bridge or the upper side of the vehicle.

In order to solve the above-mentioned problems, some techniques for replacing a conventional pipe material made of a metal material with a synthetic resin material such as fiber reinforced plastics (FRP) have been disclosed. The synthetic resin material of high strength as described above is lighter than the metal material, and its strength is maintained, and corrosion resistance is improved, so that the service life of the drain pipe is extended.

However, even if the drain pipe is manufactured by replacing the high strength synthetic resin, the fixing means for hanging the drain pipe to the bridge is made of a conventional metal material, so that the effect of preventing corrosion is insufficient.

Therefore, it is urgent to develop a technique for manufacturing a fixing device for installing the water pipe on a structure such as a bridge as well as the drain pipe by using the above-described synthetic resin material.

At this time, the first and second mold half portions 27 and 28 extend to a predetermined length, and the mold half is recessed inward. At least one surface of the mold 30 is formed on the inner surface of each of the mold recesses to have mold surfaces 27e and 28e substantially conforming to the outer surface 30a of the support bar 30. As a result, when the both ends of the support bar 30 are fitted into the respective mold parts 27 and 28, the support bar 30 is rotated or moved or separated from the respective mold parts 27 and 28 .

The support bar 30 may be formed as a solid bar filled with the inside, but it may be hollow inside to reduce the weight and weight of the support bar 30. At this time, the cross-sectional shape of the hollow inner peripheral surface may also be formed in various shapes.

Here, the support bar 30 is preferably manufactured by extruding molten high-strength synthetic resin material into a mold cavity corresponding to the above-mentioned cross-sectional shape. In particular, high strength synthetic resin materials such as fiber reinforced plastics (FRP) have a lower material cost than conventional metal materials, and are lightweight, easy to process, and excellent in strength and corrosion resistance. Accordingly, the supporting bar 30 can be formed in various shapes in cross section, and the manufacturing cost can be reduced compared to the conventional metal bar, and the service life of the supporting bar 30 can be remarkably extended even in an environment in which water is frequently exposed. .

The first mold clamping portion 27 and the second mold clamping portion 28 are respectively formed from the upper surfaces of the first clamping surface portion 25 and the second clamping surface portion 26, w3) of the upper surface portions 27c and 28c.

The width w3 of the supporting bar 30 may be set to be greater than the width w1 and w2 of the inner and outer moldings 27 and 28, respectively. As a result, both end portions of the support bar 30 are constrained to the inside of the respective angled portions 27 and 28 formed on the respective brackets 21 and 22, so that a rigid fastening state can be maintained without a separate fixing means.

The side wall reinforcement portion 27d may be formed on the first mold half 27 to improve the supporting strength of the first bracket 21 where the load of the pre-water tube portion 3 is concentrated.

More specifically, the first bracket 21 is fixed to the bracket A by means of the fixing member 29 and the direction of the force fixed to the bridge A by the fastening member 17, And may be concentrated at the connection portion between the first fixing surface portion 23 and the first coupling surface portion 25. At this time, the side reinforcing portion 27d protrudes upward from the first fastening surface portion 25 and is connected to the upper surface portion 27c, and one side edge is formed integrally with one surface of the first fixing surface portion 23 do. Accordingly, the side reinforcing portion 27d is orthogonal to the first fixing surface portion 23 and is orthogonal to the first coupling surface portion 25 to serve as a rib that provides a stiffness, The bearing force against the load applied to the bracket 21 can be improved.

Since the one end of the support bar 30 is engaged with the upper and lower inner circumferential surfaces of the first fused portion 27 and the inner circumferential surface of the side reinforcing portion 27d is also engaged with the first bracket 21, The bonding force between the support bars 30 can be remarkably improved. Of course, the second bracket 22 may also be formed with the side reinforcing portion as in the case of the first bracket 21, and such modifications fall within the scope of the present invention.

The fitting protrusions 27a and 28a are formed on the inner side of the respective mold parts 27 and 28 so that the hollow inner circumferential surface 30b of the supporting bar 30 is fitted into the fitting protrusions 27a and 28a. At least one or more restraining projections 31 are formed on the inner circumferential surface 30b of the support bar 30 along the longitudinal direction and the restraining protrusions 31 are formed on the outer circumferential surfaces of the protrusions 27a and 28a The restricting grooves 27b and 28b can be formed.

That is, even if the sectional shape of the outer peripheral surface 30a and the inner peripheral surface 30b of the support bar 30 is formed circular as the restricting projection 31 and the restricting grooves 27b and 28b are slidingly coupled, So that a stable fastening structure can be maintained. Even if the inside of the support bar 30 is hollow, the thickness of the protrusions 27a and 28a is substantially increased by the protruding thickness of the protrusion protrusion 31, so that the support bar 30 has durability Can be improved. In addition, since the contact area between the outer surface of the shoulder projecting portion 31 and the inner surfaces of the restricting grooves 27b and 28b is increased, the bonding force may be further improved.

Of course, depending on the case, the restricting protrusion may protrude outside the outer surface of the fitting protrusion, and the restricting groove may be formed in the inner circumferential surface of the supporting bar, which is formed with the fitting protrusion, into which the restricting protrusion is slidably inserted. Furthermore, the restricting protrusions and the restricting grooves may be respectively formed on the mutually facing surfaces of the inner surface of the respective mold parts and the outer surface of the support bar, and such modifications are within the scope of the present invention.

The inner circumferential surface profile of the support bar 30 corresponds to the outer circumferential profile of the protruding protrusions 27a and 28a and more preferably the inner circumferential profile of the support bar 30 is greater than that of the protruding protrusions 27a and 28a It can be formed small. Accordingly, both end portions of the support bar 30 can be more firmly coupled to the respective mold half portions 27 and 28 and can be minimized to be separated by an external impact.

Although not shown in the drawing, both ends of the support bar 30 and the respective mold portions 27 and 28 (not shown in the drawings) are provided so as to restrain the state in which both ends of the support bar 30 are inserted into the respective mold- And a fixing pin which vertically passes through the fixing pin.

The first bracket 21 and the second bracket 22 are made of rigid polyvinyl chloride resin, polyamide (PA) resin, polyethylene (PE) resin, polypropylene polypropylene, PP) resin, polycarbonate (PC) resin, polybutylene terephthalate (PBT) resin, and acrylonitrile-butadiene-styrene resin Or a mixture of at least one of them.

Further, since each member of the fixing device 20 is made of a composite material in which at least one kind of material is mixed, it is possible to improve the bonding force between the respective members by the fit- Strength can be provided.

The support bar 30 can be easily manufactured by extruding or extruding a high strength synthetic resin material such as fiber reinforced plastic as described above. At this time, the fiber-reinforced plastic provides a strength corresponding to that of a conventional metal material, and is lightweight and easy to manufacture in various forms.

That is, since each member of the composite pipe fixing device 20 for a drain pipe is manufactured by injection molding and extruding molten synthetic resin material into a mold corresponding to the above-mentioned shape, it is easy to manufacture even a complicated shape. In addition, since each member can be mass-produced in a predetermined standard, the composition can be remarkably improved.

Accordingly, in order to prevent corrosion, the fixing device 20 for fixing the drain pipe 5 made of high-strength synthetic resin such as fiber-reinforced plastic to one side of the structure is also made of a synthetic resin material. As a result, the corrosion resistance and the salt resistance are remarkably improved, so that the corrosion by the snow remover applied for excellent / wastewater and snow removal can be prevented, and the service life can be remarkably prolonged. Also, since the synthetic resin material is lighter than conventional metal materials and has excellent corrosion resistance and strength, the installation property can be remarkably improved.

In addition, in place of the conventional steel fixing means, the members of the composite pipe fixing device 20 for a drain pipe made of a synthetic resin material are firmly assembled by a simple method in which they are mutually fitted. This eliminates the need for a separate adhesive or fastening means and facilitates the installation of workers, resulting in significantly improved installation.

The supporting bar 30 is formed in a hollow shape and the outer peripheral surface 30a of the supporting bar 30 is fitted into the first and second mold half portions 27 and 28, And the engaging protrusions 27a, 28a for engaging the inner circumferential surface 30b of the support bar 30 are formed in the inner side of the respective mold grooves. Accordingly, the joint strength between the respective members is remarkably improved, and the water pipe 5 can be stably fixed to one side of the structure. Furthermore, the maintenance can be improved because the parts are not permanently fixed by welding or the like but can be fixed and fixed by fitting.

Also, since the inner circumferential surface of the support bar 30 is formed hollow to improve the lightweight property, the constraining protrusion 31 protruding in the longitudinal direction of the inner circumferential surface can reinforce the thickness to maintain the support strength, And 28 are formed with constraint grooves 27b and 28b which are formed with the constraining protrusions 31 so that the support bars 30 can be coupled more firmly and stably.
