Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a barrier rib structure,

The present invention relates to a partition wall structure installed in the wind direction of a tunnel and a method of constructing the same. More particularly, the present invention relates to a wind wall partition structure which can be easily installed in a state in which a wind- will be.

In Korea, where more than 70% of the country is made up of mountains, the construction of large cross section tunnels has been actively carried out since the construction of railways and roads and the development of underground spaces such as subways have greatly increased the underground excavation works.

Such a tunnel structure should be equipped with tunnel ventilation system considering efficiency according to traffic volume and tunnel length in order to protect tunnel users from emergency situations such as smoke, harmful gas, dust, In addition, since the tunnel structure has a serious influence on the tunnel passenger and the human body of the driver, the air pollution due to the automobile exhaust gas running in the tunnel structure must have the necessary ventilation equipment by proper ventilation calculation.

As such, the exhaust gas emitted from the running vehicle in the tunnel is the air condition for maintaining the allowable concentration of these exhaust gases below the appropriate level due to smoke, carbon monoxide (CO), nitrogen oxides (NOx), and the like. When the air is installed in the tunnel, the exhaust gas of the vehicle is diluted and the polluted air is easily discharged to the outside of the tunnel. Therefore, the environment in the tunnel can be kept fresh and pleasant, and the material affecting visibility such as soot and dust is diluted It is possible to obtain an effect of assisting safe driving. In addition, there is an advantage that the recovery time of the environment in the tunnel is minimized as well as the rapid flue gas treatment in case of an accident such as a fire in a tunnel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a wind direction to be installed in a tunnel will be described in detail with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view of a conventional wind tunnel, FIG. 2 and FIG. 3 are a vertical sectional view and a horizontal sectional view of a conventional wind shielding partition wall structure, FIG. 4 is a side view of a conventional wind shielding partition wall structure, Fig. 3 is a view showing a construction process of the wind damper barrier structure of Fig.

The wind direction is a type of air duct provided by a wind direction bottom slab 20 that is seated on a key block 12 protruding from the inner wall of the tunnel lining and is divided into a partition wall 30 and the exhaust air flow rate 22 and the air supply air flow rate 24, respectively. The exhaust air flow rate 22 is an air flow rate for discharging the air inside the tunnel to the outside, and the air supply air flow rate 24 is an air flow rate for flowing fresh external air into the tunnel.

As shown in FIGS. 2 to 4, the conventional wind shielding bulkhead structure includes a lower runner 40 formed to have a C-shaped cross section and coupled to the air-conditioned floor slab 20 so that its opening side faces upward, The upper runner 50 is vertically connected to the lower runner 40 and the upper runner 50. The upper runner 50 is connected to the tunnel lining 10 such that the cross- And a partitioning wall 30 coupled to be inserted. The lower runner 40 and the upper runner 50 are fastened by the lower side anchor 42 and the upper side anchor 52, respectively.

In order for the lower and upper portions of the divided partition 30 to be drawn between the lower runner 40 and the upper runner 50 in this way, the thickness of the divided partitions 30 is smaller than the inner space width of each of the runners 40, 50 A clearance may be generated between the partition wall 30 and the runners 40, 50, thereby causing damage to components and generation of noise. Therefore, a fastening clip 60 and a fastening bolt 62 are required to fasten the partition wall 30 to the runners 40 and 50, respectively, in the conventional air barrier wall structure. An inner runner 44 is additionally provided on the bottom surface of the lower runner 40 so that the lower anchor 42 is not damaged by the load of the partition wall 30, As shown in FIG. Further, a large amount of sealing member 70 is additionally applied to seal the gap between the components so that the flame and the smoke are not diffused when a fire occurs.

As mentioned above, since the conventional wind shielding partition wall structure requires various kinds of parts for installing the partition wall 30 on the wind-induced floor slab 20, it is difficult to construct the wind shield and the installation cost is high. There is a drawback that the structure becomes complicated and the possibility of breakage of parts is increased.

In the conventional wind shielding partition wall structure, the lower runner 40 and the upper runner 50 are first to be joined to the air-bearing floor slab 20 and the tunnel lining 10, respectively, and then the partition wall 30 is inserted. If the height of the partition wall 30 is made equal to the distance between the upper surface of the inner runner 44 and the bottom surface of the upper runner 50, the partition wall 30 is divided into the lower runner 40 and the upper runner 50 50). Therefore, when the partitioning barrier 30 is completely installed, the upper end of the partitioning barrier 30 must be spaced apart from the upper runner 50, so that the structural rigidity of the partitioning barrier 30 is lowered. In order to install the partitioning barriers 30, the upper ends of the partitioning ribs 30 are inserted into the upper runner 50, the lower ends of the partitioning ribs 30 are positioned on the lower runner 50, So that a large manpower is required to install the partitioning barrier 30.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

6 is a vertical cross-sectional view of the air barrier wall structure according to the present invention.

The air-barrier wall structure according to the present invention divides the air-conditioner installed in the upper space of the space in which the vehicle travels into two parts in the longitudinal direction in the inner space of the tunnel and divides the air-conditioner 22 for exhausting and the air- And is configured to vertically divide the upper space isolated by the wind-induced floor slab 20, as in the conventional wind-up seam structure shown in Fig. The functions and advantages obtained by dividing the upper space of the air-bearing floor slab 20 into two parts by vertically dividing the air-compartmented partition wall structure according to the present invention into the exhaust air-flow degree 22 and the air- 5, the detailed description thereof will be omitted.

2, various components such as an inner runner 44, a fastening clip 60, a sealing member 70 and the like are indispensably required in addition to the partition wall 30, There is a problem in that it is difficult to install the partitioning barriers 30 as shown in FIG. The present invention has been made in order to solve the above problems and it is possible to reduce the construction cost by reducing the number of parts and simplify the construction period of the partition wall structure, .

That is, as shown in FIG. 6, the air-compartment partition wall structure according to the present invention includes a partition wall 100 vertically erected on the air-surface floor slab 20, a partition wall 100 having a cross- A pair of lower runners 210 and a pair of upper runners 310 for coupling the lower and upper sides of the wind floor slab 20 to the upper surface of the wind tunnel floor slab 20 and the front surface of the tunnel lining 10, And a lower side anchor 230 and an upper side anchor 330 for fastening the upper side runner 310 to the upper surface of the air bearing bottom slab 20 and the front surface of the tunnel lining 10.

6) is placed on the air-bearing floor slab 20, and the other side (the side extending in the vertical direction in Fig. 6) 100, respectively. At this time, one side of the pair of lower runners 210 is fastened to the air-conditioned floor slab 20 by being fastened to a pair of lower anchors 230 partially embedded in the upper surface of the air-side floor slab 20.

6) is mounted on the front surface of the tunnel lining 10, and the other side (the side extending in the vertical direction in Fig. 6) Side surface and the right-side surface of the main body 100, respectively. At this time, one side of the pair of upper runners 310 is fastened to the upper surface of the tunnel lining 10 by being fastened to a pair of upper anchors 330 partially embedded in the front surface of the tunnel lining 10.

As described above, since the lower end and the upper end of the partition wall 100 are not in contact with the lower anchor 230 or the upper anchor 330, the inner runner 44 shown in Fig. Since the left and right sides of the divided partition wall 100 are in close contact with the lower runner 210 and the upper runner 310 respectively, the fastening clip shown in FIG. 2 is not required, and the structure is very simple. Therefore, the air barrier structure according to the present invention is advantageous in that the installation cost is significantly reduced by reducing the number of components, and the components are brought into close contact with each other, thereby eliminating the risk of collision between components due to external force.

Further, since the conventional partitioning wall 30 is fastened with the fastening bolt 62 when it is combined with the runners 40 and 50, a bolt hole is necessarily produced. Since the partition wall 30 having the bolt holes is difficult to be reused, there is a disadvantage that only the new partition wall 30 should be used in designing or reinstalling the air barrier wall structure. Of course, if the runners 40 and 50 are combined with the positions of the bolt holes formed in the partition wall 30, the partition wall 30 can be reused. However, since there are design tolerances and assembly tolerances of the components, There is a great deal of difficulty in joining the runners 40, 50 in accordance with the position of the bolt hole formed in the bolt hole. In contrast, according to the present invention, the lower portion of the partition wall 100 is pressed and fixed between the pair of lower runners 210, and the upper portion of the partition wall 100 is connected to the pair of upper runners 310, So that it is not necessary to fasten another fastening bolt. That is, since the partitioning barrier 100 used in the present invention does not cause damage such as a bolt hole, the partitioning barrier 100, which has been used once, can be reused as it is, There is an advantage that it can be saved significantly.

2, the lower anchors 42 and the upper anchors 52 are embedded at the positions where the partition walls 30 are seated, so that the partition walls 30 are sandwiched between the air side slabs 20 The partition wall 30 does not completely separate the exhaust wind direction 22 and the exhaust air flow 24 from each other. However, since the lower anchors 230 and the upper anchors 330 are not buried at the positions where the divided barrier ribs 100 are seated, the air barrier rib structure according to the present invention has the entire bottom surface of the divided barrier ribs 100 The upper surface of the partition wall 100 may contact the upper surface of the tunnel lining 10 and the upper surface of the partition wall 100 may contact the upper surface of the tunnel lining 10. When the lower end of the partition wall 100 and the upper end of the partition wall 100 are in close contact with the upper surface of the air bearing bottom slab 20 and the front surface of the tunnel lining 10, the exhaust air- There is an advantage that a separate sealing work for isolating the exhaust wind direction 22 from the exhaust air flow 24 can be omitted.

Hereinafter, with reference to the accompanying drawings, a method for constructing the air barrier wall structure according to the present invention shown in FIG. 6 will be described in detail.

7 to 9 sequentially illustrate the construction process of the air barrier rib structure according to the present invention.

In order to construct the windproof barrier rib structure according to the present invention, first, a pair of lower runners 210, a pair of upper runners 310, and a plate-shaped partition wall 100 are formed so as to have a cross- 7, one side of the lower runner 210 (the side extending in the horizontal direction in FIG. 7) is fastened to the air-bearing floor slab 20, and one side of the upper runner 310 In Fig. 7, the side extending in the horizontal direction) to the ceiling surface of the tunnel lining 10. 7) and the inner surface of the other side of the upper runner 310 (the left side of the side extending in the vertical direction in Fig. 7) of the lower runner 210 The inner surface of the lower runner 210 and the inner surface of the other end of the upper runner 310 should be arranged in a line so as to form a single plane.

Since the lower runner 210 and the upper runner 310 are pressed in the horizontal direction on the outer surface of the divided barrier rib 100 to support the divided barrier rib 100 in the horizontal direction, You will receive strength. Therefore, when the lower runner 210 and the upper runner 310 are coupled to the wind direction bottom slab 20 and the tunnel lining 10, the wind direction bottom slab 20 and the tunnel lining 10 are provided on the lower side It is preferable that the lower runner 210 and the upper runner 310 are fastened to the lower anchor 230 and the upper anchor 330 after the anchor 230 and the upper anchor 330 are first embedded. When the lower runner 210 and the upper runner 310 are coupled to the lower anchor 230 and the upper anchor 330 so that the lower anchor 230 and the upper anchor 330 are not broken, The runner 210 and the upper runner 310 can be held in a fixed state, so that a large support force can be generated.

As shown in FIG. 7, when one lower runner 210 and one upper runner 310 are coupled to each other, upper and lower side surfaces (right side surfaces in FIG. 8) of the divided barrier ribs 100 (The left side in the vertical direction in Fig. 7) of the lower runner 210 and the inner side (the left side in the side extending in the vertical direction in Fig. 7) of the upper runner 310, Thereby positioning the partition 100. When the partitioning barrier rib 100 is completely seated, one side of the other lower runner 210 (the side extending in the horizontal direction in Fig. 9) and the other side (the side extending in the vertical direction in Fig. 9) 9) and one side (the side extending in the horizontal direction in Fig. 9) of the other upper side runner 310 and the other side (the side extending in the horizontal direction in Fig. 9) (The side extending in the vertical direction in Fig. 9) are brought into close contact with the top surface of the tunnel lining 10 and the other surface on the upper side of the partition wall 100 (the left surface in Fig. 9) 9) of the upper runner 310 is coupled to the wind direction bottom slab 20 and one side of the upper runner 310 (the side extending in the horizontal direction in FIG. 9) is connected to the front surface of the tunnel lining 10 By doing so, the air barrier rib structure shown in Fig. 6 can be completed. 9, the anchors for the lower runner 210 and the upper runner 310 are omitted so as to clearly show the engaging positions of the lower runner 210 and the upper runner 310 that are newly coupled to each other The lower runner 210 and the upper runner 310 that are newly engaged are connected to the lower side anchor 230 and the upper side anchor 330 in the same manner as the lower side runner 210 and the upper side runner 310 The bottom floor slab 20 and the tunnel lining 10, respectively.

As described above, by using the method of constructing an air barrier wall structure according to the present invention, after the lower runner 210 and the upper runner 310 have been fastened, the divided barrier ribs 100 are not mounted, Only one lower runner 210 and one upper runner 310 of the upper runner 210 and the upper runner 310 are coupled to each other to position the divided barrier ribs 100, The divided partition wall 100 can be installed even if the height of the divided partition wall 100 is set equal to the interval between the air-conditioned floor slab 20 and the tunnel lining 10. That is, the lower end and the upper end of the partition wall 100 can be brought into contact with the air under floor slab 20 and the tunnel lining 10, respectively, by using the construction method of the air barrier wall structure according to the present invention, The left and right side surfaces of the divided partition wall 100 are pressed between the pair of lower runners 210 and the pair of upper runners 310, There is an advantage that the phenomenon of shaking in the vertical direction or the lateral direction can be prevented.

When the conventional partition wall 30 is installed on the runners 40 and 50, the partition wall 30 is lifted up as if the window is inserted into the window frame, It is necessary to insert the partition wall 30 into the lower runner 40 by inserting the partition wall 50 into the lower runner 40. Therefore, However, by using the method of constructing the wind shielding barrier rib structure according to the present invention, the divided barrier ribs 100 can be mounted only by horizontally pushing the divided barrier ribs 100 without moving upward or downward the divided barrier ribs 100 It is advantageous that the construction work of the barrier rib structure becomes very simple.

A pair of lower runners 210 and upper runners 310 are pressed against the left and right sides of the divided partition wall 100 to fix the divided partition wall 100 so that the divided partition wall 100 is provided with bolt holes, The same binding mark is not generated. Accordingly, when the partition wall structure 100 according to the present invention is used, no damage is applied to the partition wall 100, so that the partition wall 100 can be reused, There is an advantage of being able to save considerably.

10 to 12 are a perspective view, a side view, and a plan view of a partition wall included in the air barrier wall structure according to the present invention.

Meanwhile, as shown in FIG. 10 to FIG. 12, a plurality of through holes 110 having a length in the vertical direction may be formed inside the partition wall 100 so as to have a high vertical support force. The partition wall 100 is formed with a protruding portion 121 and an inlet portion 121 so that two adjacent partition wall portions 100 can be aligned and fixed when the partition wall portions 100 are connected to each other. (122) may be formed. When the projection 121 and the inlet 122 are formed in the partitioning barrier 100 as described above, when two or more partitioning walls 100 are arranged in series, one of the partitioning walls 100 protrudes from the adjacent partitioning The partition structure can be maintained in a constant arrangement structure by being drawn into the inlet portion 122 of the partition wall 100. [

In this case, when the plurality of through holes 110 are formed in the partition wall 100, the support force in the vertical direction relative to the weight is increased, but the bending strength and the compressive strength are somewhat lowered. Therefore, The divided barrier ribs 100 may be easily deformed or damaged.

Therefore, in order to improve the bending strength and the compressive strength of the partition wall 100, the reinforcement unit 130 is inserted into at least one of the through holes 110 of the plurality of through holes 110 in a fitting manner. . At this time, the reinforcing unit 130 should be made of metal or reinforced plastic having higher mechanical rigidity than the partitioning barrier 100.

When the reinforcing unit 130 is inserted into the through hole 110 of the partition wall 100 as described above, the bending strength and the compressive strength of the partition wall 100 can be improved while maintaining a high vertical / There is an advantage that the durability can be improved. Also, as shown in FIGS. 11 to 13, the partition walls 100 may have different strengths depending on various conditions such as the kind, size, and use of the tunnel. When the reinforcing unit 130 is further inserted into the through hole 110, the strength of the divided partition wall 100 can be adjusted appropriately by increasing or decreasing the number of the reinforcing units 130 inserted into the one partitioning wall 100 Therefore, there is an advantage that the divided partition wall 100 can be commonly used irrespective of the type of the air barrier wall structure.

The sectional shape of the through hole 110 is entirely changed when the divided partition wall 100 is twisted or curved so that the reinforcing unit 130 is formed so that the strength of the divided partition wall 100 can be enhanced, The through hole 110 may be formed in a shape of a pipe which is in close contact with the entire inner surface of the through hole 110. When the divided barrier ribs 100 are twisted or warped, moments or torsional stresses are transmitted to the reinforcing unit 130 immediately after the entire outer surface of the reinforcing unit 130 is closely attached to the entire inner surface of the through holes 110. [ So that the effect of reinforcing the strength of the partition ribs 100 is very high.

The shape of the reinforcing unit 130 is not limited to the shape of the through hole 110. The shape of the reinforcing unit 130 is not limited to the shape of the through hole 110, And the like.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It will also be appreciated that many modifications and variations will be apparent to those skilled in the art without departing from the scope of the present invention.
