10 bottom plate tube 30 mold

The present invention relates to a fiber-reinforced composite bottom plate of a hollow section and a bridge structure provided with the same, and specifically, a precast bottom plate made of a fiber-reinforced composite material having a hollow section. Hereinafter, the hollow section of the hollow section to which the snow and ice sheets which melt the snow or ice accumulated on the bottom plate is melted by blowing hot air into the hollow formed in the bottom plate tube which is abbreviated as "composite bottom plate". The present invention relates to a fiber reinforced composite bottom plate and a bridge structure having the same.

If snow accumulates or freezes on the road surface in winter, the method of removing it is to spray calcium chloride. However, the use of calcium chloride causes environmental pollution. Calcium chloride not only corrodes the vehicle, but also degrades the pavement and concrete deck of the bridge. Particularly in the case of the floor plate made of reinforced concrete, calcium chloride can penetrate the inside of the floor plate through corrosion in the floor plate and corrode the reinforcing steel bar. Serious damage to the bridge, resulting in a shorter bridge life. Also, when the snow melts, the melted snow is frozen again to form an ice sheet, and there is a problem that the frozen ice cannot be melted with calcium chloride. When the upper part of the bottom plate is frozen, it causes a traffic accident. Therefore, not only snow removal but sea ice that can eliminate the freezing condition is necessary but there is a limit that cannot achieve all with calcium chloride.

As an alternative to the use of calcium chloride, the idea of heating and melting the bottom plate itself has been proposed in the past by laying an electric heating wire inside the bottom plate of the bridge. However, in the sea ice structure using the hot wires, electric heating wires are often disconnected due to vehicle traffic, and when the hot wires are disconnected, the thawing function is sharply degraded. In particular, even if the hot wire is damaged, it is difficult to find the damaged hot wire, and in order to repair the damaged hot wire, the bridge bottom plate itself must be partially broken, so repair of the damaged hot wire is virtually impossible. For this reason, attempts to impart a thawing function to bridges using hot wires are rarely put to practical use.

On the other hand, in recent years, in order to solve the various disadvantages of the concrete deck, a bridge using a composite deck is proposed and put to practical use. Figure 6 shows a schematic perspective view of a composite deck plate bridge developed by the present inventors and applied by a method filed in Patent Application No. 2003-37663. In the case of the composite deck plate bridge as well as in the winter, there may be a problem due to freezing or snowing of the road surface in the winter, as described above, in the case of the conventional snow removal and thawing method using calcium chloride or hot wire Since there are several problems, it has been actively seeking new snow removal and thawing methods that are suitable for composite deck bridges and can solve the above problems.

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

Figure 1 shows a schematic perspective view of a bridge with a fiber reinforced composite bottom plate 1 (hereinafter abbreviated as "composite bottom plate") having a snow removal and thawing function according to the present invention. 2A to 2C are schematic views showing an example of a structure in which the composite bottom plate 1 of the present invention is formed by combining the composite tubes each having a hollow. 3A and 3B show cross-sectional views taken along lines A-A and B-B of FIG. 1, respectively, and FIG. 3C shows a detail of circle C of FIG. 3A.

As shown in FIGS. 1 and 2A to 2C, the composite bottom plate 1 includes a bottom plate tube 10 having a plurality of hollows 11 arranged in an orthogonal direction and each bottom plate tube 10 in an axial direction. Side) are manufactured by integrally connecting and assembled in parallel to be coupled to each other. The bottom plate tube 10 is made of a glass fiber and a resin selected from polyester, vinyl ester, panol or epoxy. Thus, the composite bottom plate (1) made of a combination of the bottom plate tube 10 is installed on the mold 30 disposed in the axial direction to be integrally combined with the mold 30 to form a bridge.

In the present invention, the hot air flows inside the hollow 11 of the bottom plate tube 10 forming the composite bottom plate 1 as described above, so that the bottom plate 1 is heated to be stacked on the top surface of the bottom plate 1. Snow or thaw snow or ice. That is, the hollow 11 of the bottom plate tube 10 forms a hot air passage.

In the present invention, in order to circulate the hot air flows along the hollow 11 of the bottom plate tube 10 side to the sides of the composite bottom plate (1) as shown in Figure 3a and 3c side can communicate The ventilation channel 22 is formed. Specifically, the closing channel member 20 is installed to form a predetermined space outside the hollow 11 opening surface of the bottom plate tube 10, the space formed by the closing channel member 20 This is to form a side ventilation channel (22). Inside the finishing channel member 20, a ventilation guide film 21 for partitioning the ventilation channel is disposed at predetermined intervals. The arrangement position of the ventilation guide film 21 depends on how to configure the ventilation path as will be described later.

At one side edge of the composite bottom plate 1, the finishing channel member 20 is formed with an inlet 23 through which air is blown from the outside. When a heater (not shown) is installed at an appropriate position of the bridge to form hot air, the hot air enters the side vent channel 22 through the inlet 23 and flows along the hollow 11. When the hot air warmed to a predetermined temperature in this way flows along the hollow 11, snow or ice accumulated on the upper surface of the composite bottom plate 10, that is, the upper surface of the bridge, naturally melts by the hot air. As shown by the arrows in FIG. 1, the hot air discharged through the outlet 24 may be recovered, reheated and recycled through a channel, a separate conduit, or other piping configuration, which will be described later.

Next, various structures of a ventilation path through which hot air flows will be described with reference to FIGS. 4A to 4C. 4A is a plan view of the composite bottom plate 1 shown in FIG. 1, and FIGS. 4B and 4C are top views of the composite bottom plate 1 similar to FIG. 4A, but have a ventilation path different from that of FIG. 4A. A plan view showing an example. The dotted lines marked with reference numeral 14 in FIGS. 4A-4C indicate the position of the inner abdominal plate 12 (see FIGS. 2A and 2B) forming the hollow 11 inside the bottom plate tube 1, and reference numeral 15. The solid line marked with denotes the coupling part 15 between the bottom plate tube 1.

First, in the embodiment shown in Figure 4a, the hot air flowing through the inlet port 23 of the closing channel member 20 in one side of the composite bottom plate 1, as indicated by the arrow, the bottom plate tube (10) After passing through the hollow 11 of the right and left and is discharged through the outlet (24). When the length of the composite bottom plate 1 is long in the axial direction, a predetermined number of bottom plate tubes 10 are partitioned into one unit, and inlets 23 and outlets 24 are separately formed in each unit. The distance which hot air flows can be adjusted suitably.

Meanwhile, as shown in FIG. 4B, the outlet 24 may be installed toward the inlet 23 so that several bottom plate tubes 10 may be partitioned into one unit and circulated.

In the case of the embodiment shown in Figure 4c, the composite bottom plate 1 is divided into units having a predetermined number of bottom plate tubes 11, and hot air discharged from the last bottom plate tube 10 of each unit, Collected in one collection channel 26 is sent back to the heater to be heated again and then sent to the bottom plate tube 10 at the beginning of each unit has a structure to circulate back to communicate with the hollow (11). In the embodiment of Figs. 4A to 4C, it is preferable to recirculate the hot air by re-heating the hot air discharged to the outlet 24 after the circulation is finished.

In the present invention as described above it is possible to form a hot air ventilation path of the various forms by changing the side ventilation channel 22 by arranging the ventilation induction film 21 in various forms on the inside of the finishing channel member 20.

In addition, the above-described embodiment has a structure in which hot air is heated to a predetermined temperature by a heater and sent to the inlet port 23, which is deformed so that a small heater is provided in the bottom plate tube in the side vent channel 22. It may be disposed at the inlet of the hollow 11 of 10, and simply blows air through the inlet 23 to allow the hot air to flow through the hollow 11. In addition, when the speed of hot air decreases while flowing through the side vent channel 22 and the hollow 11, a forced blower (not shown) is disposed at a predetermined position such as the inlet of the hollow 11 in the side vent channel 22. The speed of hot air can also be maintained appropriately.

The heater, blower, etc. may be configured to control the operation by remote control using a wireless or wired, it may be configured to be controlled automatically according to a predetermined setting as well as manual. The control method of the heater and the blower can use a variety of well-known techniques, and further description thereof will be omitted.

On the other hand, in order to synthesize the composite bottom plate 1 integrally with the mold 30, as shown in Figure 3a and 3b, the shear connector 31 provided in the mold 30 is the inner side of the bottom plate tube (10) In the inserted state, the bottom plate tube (10) of the insertion portion of the shear connector 31 has a connection structure to fill the filler 32. FIG. 5A shows a circle E partial detail of FIGS. 4A-4C, and FIG. 5B shows a detail of circle D of FIG. 3B. As shown in FIGS. 4A to 4C, 5A, and 5B, the hollow 11 of the bottom plate tube 10 may be blocked in the direction perpendicular to the axial direction at the portion where the connecting structure 31 and the connection structure are formed. Since a plurality of hollows 11 are formed in one bottom plate tube 10 and only some of the hollows 11 are formed such a connection structure, hot air communicates in a perpendicular direction through the other open hollows 11. There is nothing wrong with it.

However, in the present invention, even when a part of the hollow 11 is blocked by the connection structure as described above, the hot air may be further provided with the following structure to communicate more smoothly. That is, as shown in FIGS. 5A and 5B, the tubular member 33 is embedded in the filler 32 in which the shear connection member 31 is embedded, so that hot air can communicate through the filler 32 in the direction perpendicular to the axial axis. It is to further provide a structure to make. When the pipe member 33 is embedded as described above, the pipe member 33 is filled even when a part of the hollow 11 is filled with the filler 32 for shear connection between the composite base plate 1 and the mold 30. Through the hot air is able to communicate in the orthogonal direction in the hollow 11 through, the hot air can be circulated more efficiently, thereby exhibiting a better snow removal and thawing function of the bottom plate. In FIG. 5A, reference numeral 34 denotes a foam dam member 34 that limits the filling area of the filler 32. In the embodiment shown in the figure only two tube members 33 are shown, but the number of the tube member 33 is not limited to this, one or two or more of the plurality of tube members 33 may be disposed.

As described above, in the present invention, the hot air is communicated through the hollow 11 of the bottom plate tube 10 forming the composite bottom plate 1, thereby heating the composite bottom plate 1 to the upper surface of the bridge. Not only can the snow melt by melting snow, but it can also thaw on the top of the bridge due to melted snow or other causes.

Therefore, in the present invention, it is possible to solve the problems of environmental pollution, insufficient snow removal and thawing function which occur in the conventional snow removal and thawing method using calcium chloride or hot wire.

In particular, in the prior art using a hot wire, it is virtually impossible to repair or repair it when the hot wire is disconnected, but the disconnection phenomenon does not occur at all in the present invention.

In the above described the configuration and features of the present invention based on the embodiment according to the present invention, the present invention is not limited to this and can be changed freely according to the technical idea of the present invention.
