Description

Technical Field

[0001] The utility model relates to a top surface partition structure of a tunnel, in particular to a tunnel ceiling partition, and also relates to a fixing structure of the tunnel ceiling partition. Background Art

[0002] The purpose of tunnel ventilation is to remove harmful gases, smoke, dust and other pollutants in the tunnel, keep the air in the tunnel fresh, prevent accidents such as fire and explosion, and improve the service life and efficiency of the tunnel.

[0003] The existing horizontal guide ventilation is one of the most commonly used ventilation methods. Its basic structure is to set horizontal partitions in the tunnel to separate the tunnel into two independent spaces, the lower space as the fresh air duct and the upper space as the exhaust duct. The air is transported from the fresh air duct to the exhaust duct through fans or natural wind to achieve ventilation and smoke exhaust in the tunnel.

[0004] Existing flat-duct ventilation systems often use a fixed partition wall structure. This structure consists of corrugated panels with inclined surfaces on either side. These surfaces are riveted to the tunnel's sloping roof. Horizontal bolts secure the multiple fixed partition walls together, creating a horizontal connection. This structure is referenced in the utility model patent publication number CN 221169629 U.

[0005] However, the above structure was found to have the following disadvantages during actual use: 1. Multiple fixed partition walls are locked together by horizontal bolts. When this structure is erected over long distances and large spans, the vertical shear force of the horizontal bolts increases, posing a greater risk of shearing, and in severe cases may even cause the fixed partition walls to collapse; 2. The left and right sides of the fixed partition wall are connected to the inclined roof of the tunnel through inclined surfaces and riveted. This riveted structure has poor sealing properties, which can easily lead to penetration of the upper and lower spaces, making it impossible to achieve closed circulation ventilation to the maximum extent possible.

[0006] In response to the above-mentioned drawbacks, as technicians in the field of air energy, the technical problem that urgently needs to be solved is: how to improve technology and design a tunnel ceiling partition and its fixing structure, which can improve the strength of the structure and ensure the combined strength after multiple assemblies, so as to solve the above technical problems existing in the existing technology. Utility Model Content

[0007] In view of the shortcomings of the prior art mentioned above, the present invention proposes a tunnel ceiling partition and its fixing structure, which adopts a novel tunnel ceiling partition and a superimposed structure to achieve fixation, so that its horizontal bolts only serve as auxiliary locking components, effectively improving the overall combination strength.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] A tunnel ceiling partition comprises a corrugated plate, wherein front and rear steel rib beams are provided on both the front and rear sides of the corrugated plate, wherein the front and rear steel rib beams are both right-angled plates and are welded and fixed to the corrugated plate as a whole; longitudinal flanges are provided on the left and right sides of the corrugated plate, wherein the longitudinal flanges are welded to the left and right ends of the corrugated plate as a whole, and an elastic arc surface is provided on the top of the longitudinal flanges; and hoisting holes are provided on the front and rear steel rib beams.

[0010] The bottom surface of the corrugated plate is provided with a bottom plate. The four sides of the bottom plate are respectively welded to the front steel rib beam, the rear steel rib beam and the longitudinal flange. A support frame is provided between the bottom plate and the corrugated plate.

[0011] A tunnel ceiling partition fixing structure includes a support fixed on the inner wall of the tunnel, the top of the support is connected to the bottom plate, and when adjacent tunnel ceiling partitions are arranged front and back, the front and back right-angle plates overlap each other and are locked twice by horizontal bolts; a flexible sealing gasket is provided between the support and the bottom plate, and sealing is achieved after vertical locking; a lifting assembly is provided between the inner side surface of the tunnel and the front steel rib beam and the rear steel rib beam, and the elastic arc surface provided on the top of the longitudinal flange is squeezed against the inner side surface of the tunnel.

[0012] When adjacent tunnel ceiling partitions are overlapped front and back, a support beam is provided at the overlap point, and a pressure plate is provided on the support beam to achieve vertical extrusion of the horizontal surface after the right-angle plates are stacked; a baffle is also provided on the support beam, and the baffle is extruded on the right-angle plane of the right-angle plate;

[0013] The left and right ends of the support beam are fixed on the inner wall of the tunnel, and vertical support is achieved through support blocks.

[0014] The support is provided with inclined side surfaces and a top surface, and the inclined side surfaces are fixed to the interior of the tunnel to achieve horizontal support of the entire support.

[0015] The utility model has the following beneficial effects: the utility model adopts a structure combining corrugated plate and front and rear steel rib beams of right-angle structure, and longitudinal flanges are provided on both sides and the top of the longitudinal flanges are provided with elastic arc surface, when adjacent tunnel ceiling partitions are arranged in front and back, the front and rear right-angle plates overlap each other and are locked twice by horizontal bolts; a flexible sealing gasket is provided between the support and the bottom plate, and a sealing is achieved by vertical locking; a lifting assembly is provided between the inner side of the tunnel and the front and rear steel rib beams, and the elastic arc surface provided on the top of the longitudinal flange is pressed against the inner side of the tunnel.

[0024] The present invention is further described below through implementation methods. The following description is merely an exemplary explanation. Those skilled in the art can make further structural improvements based on the following explanation. The scope of protection of this patent shall be based on the scope recorded in the claims.

[0025] Example 1:

[0026] A tunnel ceiling partition, as shown in the following Figure 1 As shown, it includes a corrugated plate 4, with a front steel rib beam 1 and a rear steel rib beam 2 provided on both the front and rear sides of the corrugated plate 4. The front steel rib beam 1 and the rear steel rib beam 2 are both right-angled plates and are welded and fixed to the corrugated plate 4. The front right-angled plate 11 on the front steel rib beam 1 and the rear right-angled plate 21 on the rear steel rib beam 2 are arranged in the same direction. The left and right sides of the corrugated plate 4 are both provided with longitudinal flanges 3, which are welded to the left and right ends of the corrugated plate 4. The top of the longitudinal flange 3 is provided with an elastic arc surface 31 facing outward, and the top of the elastic arc surface is bent downward. The front steel rib beam 1 and the rear steel rib beam 2 are both provided with lifting holes 13 and locking holes 12. The locking holes 12 are used to achieve horizontal locking when connecting adjacent tunnel ceiling partitions, and the lifting holes 13 are used for vertical force application and lifting when connecting multiple tunnel ceiling partitions.

[0027] The bottom surface of the corrugated plate 4 is provided with a bottom plate 6. The four sides of the bottom plate 6 are welded to the front steel rib beam 1, the rear steel rib beam 2 and the longitudinal flange 3. A support frame 5 is provided between the bottom plate 6 and the corrugated plate 4. The support frame 5 adopts a U-shaped structure, and the vertical parts on both sides are used to connect and support the corrugated plate. The bottom surface of the support frame 5 is welded or riveted to the bottom plate for fixation. This structure can improve the bottom support strength of the corrugated plate 4 and prevent the middle of the corrugated plate 4 from collapsing.

[0028] Example 2:

[0029] A fixing structure using the tunnel ceiling partition disclosed in Example 1, such as Figures 2 to 6 As shown, it includes a support 8 fixed on the inner wall of the tunnel 7. This support 8 usually adopts a steel corbel support. The support 8 is provided with an inclined side surface 81 and a top surface 82. A support member 83 is provided between the inclined side surface 81 and the top surface 82. The inclined side surface 81 is riveted and fixed to the inside of the tunnel 7 to achieve horizontal support of the entire support 8. The top surface 82 is used for horizontal support of the tunnel ceiling partition.

[0030] When the horizontal support of the tunnel ceiling partition is realized by the support 8, the top surface 82 of the support 8 is connected to the bottom plate 6. When the adjacent tunnel ceiling partitions are arranged front and back, the front and back right-angle plates overlap each other and are locked twice by horizontal bolts, such as Figure 3As shown, the rear right-angle plate 21 is supported by the front right-angle plate 11, and is locked by vertical rivets on the horizontal overlapping surface of the front right-angle plate 11 and the right-angle plate 21, and horizontal rivet locking is achieved through locking holes 12 on the vertical overlapping surface of the front right-angle plate 11 and the right-angle plate 21.

[0031] Furthermore, a flexible sealing gasket, typically a rubber gasket 84, is provided between the support 8 and the base plate 6, which is sealed by vertically locking. A lifting assembly is provided between the inner side of the tunnel 7 and the front and rear steel rib beams 1 and 2. One end of this lifting assembly is connected to the lifting hole 13, and the other end is riveted to the inner wall of the tunnel 7. Vertical force is applied to lift the entire tunnel ceiling partition or a group of them. Because the lifting assembly is a common device in the prior art, the structural details of the lifting assembly are not detailed here.

[0032] When the above-mentioned lifting assembly is pulled vertically, the elastic arc surface 31 provided on the top of the longitudinal flange 3 is pressed against the inner side surface of the tunnel 7. The tighter the lifting assembly is pulled vertically, the tighter the elastic arc surface 31 is pressed against the inner side surface of the tunnel 7.

[0033] When adjacent tunnel ceiling partitions are overlapped front and back, a support beam 71 is provided at the overlap point, and a Z-shaped pressure plate 9 is provided on the support beam 71. The Z-shaped pressure plate 9 is used to realize vertical extrusion of the horizontal plane after the front right-angle plate 11 and the rear right-angle plate 21 are superimposed; an L-shaped baffle 91 is also provided on the support beam 71, and the L-shaped baffle 91 is extruded on the right-angle plane of the right-angle plate; the Z-shaped pressure plate 9 cooperates with the L-shaped baffle 91 to realize auxiliary fixation of the adjacent front steel rib beam 1 and the rear steel rib beam 2 after superposition.

[0034] The left and right ends of the support beam 71 are fixed on the inner wall of the tunnel 7 , and vertical support is achieved through the support blocks 72 .

[0035] To sum up, after the utility model adopts the above structural setting, it can effectively improve the overall assembly strength of the tunnel ceiling partition. After assembly, the main force points between adjacent tunnel ceiling partitions are concentrated on the overlapping surfaces of the right-angle plates, and the bolts between adjacent tunnel ceiling partitions only play an auxiliary locking role; by setting an elastic arc surface to be squeezed on the inner side of the tunnel, after the lifting component is vertically pulled and force is applied, the elastic arc surface can be constrained to deform and apply force to the inner side of the tunnel, and then the sealant is assisted to form an isolated and enclosed space above and below the tunnel ceiling partition, which can effectively improve the sealing performance.
