Description

Technical Field

[0001] The utility model relates to the field of civil air defense engineering building structures, in particular to an exhaust air and smoke exhaust pipe well structure of a mobile power station. Background Art

[0002] The building area occupied by the civil air defense mobile power station is relatively small, while the ventilation volume inside the mobile power station is usually large, which makes it difficult to arrange the air inlet and exhaust fans, ventilation ducts, and air inlet and exhaust vents. In addition, the air inlet shaft is at least 10m away from the exhaust shaft horizontally, resulting in a long and irregular exhaust and smoke exhaust structure of the civil air defense mobile power station.

[0003] This type of L-shaped exhaust and smoke exhaust shaft often uses cast-in-place reinforced concrete structure to form the air duct. Figure 1 As shown. However, due to the small area of ​​the air duct opening and the need to convert the air shaft from horizontal to vertical, it is very difficult to tie the steel bars and support the concrete formwork of the cast-in-place reinforced concrete of the air duct structure, and the quality is difficult to guarantee. Even if the pouring is successful, the formwork is often unable to be removed, affecting the exhaust area of ​​the air shaft.

[0022] 1. The embodiment of the utility model provides a mobile power station exhaust and smoke exhaust pipe shaft structure, which is also an L-shaped air duct structure, formed by combining cast-in-place and precast concrete. Specifically, the vertical section of the L-shaped air duct structure is a cast-in-place reinforced concrete vertical pipe, and a precast top cover is set on the top, while the more stable horizontal section uses a precast cross pipe. In this way, during construction, the longitudinal pipe can be cast in place first, and the template can be taken out after the concrete solidifies, and then the precast cross pipe and precast top cover are installed.

The entire structure meets the requirements of bearing capacity while also meeting the requirements of waterproofing and sealing.

[0025] In general, the embodiment of the utility model provides a mobile power station exhaust and smoke exhaust pipe shaft structure by setting the longitudinal pipe as a cast-in-place reinforced concrete vertical pipe, setting the transverse pipe as a prefabricated transverse pipe, and arranging a prefabricated top cover on the longitudinal pipe, so as to facilitate construction and improve the exhaust efficiency.

[0040] Example

[0041] like Figure 2 and Figure 3 As shown, the embodiment of the utility model provides a mobile power station exhaust smoke pipe shaft structure, including: a transverse pipe, one end of which is connected to the inside of the mobile power station 3, for receiving and transmitting the smoke inside the mobile power station 3, and transmitting it to the longitudinal pipe; a longitudinal pipe, which is connected to the other end of the transverse pipe, for receiving the smoke in the transverse pipe and discharging it to the external environment, and an exhaust window 4 is arranged on the side wall of the longitudinal pipe, and the window is arranged above the ground surface 5, so that the smoke can be directly discharged into the atmosphere; the longitudinal pipe is a cast-in-place reinforced concrete vertical pipe 2, and a prefabricated top cover 6 is arranged on the top of the longitudinal pipe; the transverse pipe is a prefabricated transverse pipe 1, and the prefabricated transverse pipe 1 is connected to the floor 7 of the mobile power station 3. Specifically, the vertical section bears the horizontal civil air defense load and needs to have sufficient bearing capacity. Therefore, the utility model adopts a cast-in-place reinforced concrete structure, and an exhaust window 4 needs to be opened at the same time, which is easier to construct than a prefabricated structure. In the embodiment of the utility model, the transverse pipe and the top cover are set as a prefabricated structure, that is, the longitudinal pipe is a structure with an upper opening and a lower opening, and the concrete formwork is convenient to support and remove, and compared with the prior art, there is no need for a cast-in-place reinforced concrete L-shaped pipe structure, which improves construction efficiency and convenience. At the same time, the cast-in-place reinforced concrete vertical pipe 2 can serve as a supporting structure for the prefabricated top cover 6 and the prefabricated transverse pipe 1, thereby improving the firmness of the entire pipe well structure.

[0042] For example, Figure 4 As shown, the longitudinal cross-section of the prefabricated transverse pipe 1 is an "inverted U" shape, and is covered on the top of the floor 7 of the mobile power station 3 to form a hollow tubular structure, that is, the channel formed by the connection between the prefabricated transverse pipe 1 and the floor 7 of the mobile power station 3 is a transverse smoke conveying channel of the pipe well structure, which ensures sufficient exhaust channel space. During installation, the prefabricated transverse pipe 1 can be directly hoisted on the floor 7. Therefore, in order to facilitate hoisting, a number of lifting ring structures 18 can be set on the top of the prefabricated transverse pipe 1. It should be noted that the location and number of the lifting ring structure 18 are not restricted here, as long as the stability and smoothness of the lifting operation can be achieved. At the same time, after the lifting is completed, one side of the prefabricated horizontal pipe 1 needs to be connected to the cast-in-place reinforced concrete vertical pipe 2, and the other side is connected to the main structure 13 of the mobile power station 3, so that a complete L-shaped exhaust and smoke exhaust channel can be formed. One end of this L-shaped exhaust and smoke exhaust channel is connected to the interior of the mobile power station 3. For example, one end is connected to the opening 19 of the mobile power station 3, and the other end is connected to the external environment through the exhaust window 4, forming a complete mobile power station 3 exhaust and smoke exhaust pipe well pipeline system.

[0043] In order to improve the connection stability between the prefabricated transverse pipe 1 and the floor 7, in an embodiment of the utility model, the exhaust and smoke exhaust pipe shaft structure also includes a first cast-in-place concrete baffle 8 and a second cast-in-place concrete baffle 9 parallel to each other, the first cast-in-place concrete baffle 8 and the second cast-in-place concrete baffle 9 are both vertically arranged with the floor 7 of the mobile power station 3, and are both provided with a plurality of pre-embedded steel bar connectors 10; the prefabricated transverse pipe 1 is arranged between the first cast-in-place concrete baffle 8 and the second cast-in-place concrete baffle 9, and the two sides of the prefabricated transverse pipe 1 are respectively connected to the first cast-in-place concrete baffle 8 and the second cast-in-place concrete baffle 9 through pre-embedded steel bar connectors 10. Specifically, the two sides of the "inverted U"-shaped prefabricated transverse pipe 1 are respectively connected to the first cast-in-place concrete baffle 8 and the second cast-in-place concrete baffle 9 through embedded steel bar connectors 10, and the prefabricated transverse pipe 1 is arranged between the first cast-in-place concrete baffle 8 and the second cast-in-place concrete baffle 9, ensuring the correct position and alignment of the transverse pipe, and also facilitating installation and subsequent maintenance work. At the same time, the first cast-in-place concrete baffle 8 and the second cast-in-place concrete baffle 9 can limit the prefabricated transverse pipe 1 without affecting the channel size of the smoke exhaust duct, and also increase the contact area with the prefabricated transverse pipe 1, thereby improving the connection stability of the entire pipe well structure. The number of embedded steel bar connectors 10 is not limited here, and can be set according to actual needs, as long as the purpose of sufficient connection stability can be achieved.

[0044] Furthermore, the two ends of the prefabricated transverse pipe 1 are respectively provided with a first boss mechanism 11 and a second boss mechanism 12, the first boss mechanism 11 is used to be engaged and connected with the main structure 13 of the mobile power station 3, and the end of the cast-in-place reinforced concrete vertical pipe 2 is provided with a bending moment structure 14, and the second boss mechanism 12 is engaged and connected with the bending moment structure 14. Specifically, the first boss mechanism 11 and the second boss mechanism 12 can not only increase the connection area between the prefabricated transverse pipe 1 and the main structure 13 and the bending moment structure 14 of the mobile power station 3, but also realize the engagement in the structure, strengthen the bearing capacity of the joint, and play a role in physical waterproofing and radiation protection. The design of the bending moment structure 14 at the end of the cast-in-place reinforced concrete vertical pipe 2 can provide additional bending resistance. Through the connection of the boss mechanism and the bending moment structure 14, the structural integrity of the entire exhaust and smoke exhaust pipe shaft is strengthened, which helps to improve the reliability and durability of the system. Preferably, the first boss mechanism 11 is connected to the main structure 13 of the mobile power station 3 through a pre-embedded steel bar connector 10, and the bending moment structure 14 is connected to the second boss mechanism 12 through a pre-embedded steel bar connector 10. More preferably, the first boss mechanism 11 and the main structure 13 of the mobile power station 3 are connected on end faces with water-swellable sealing pads 20, and the second boss mechanism 12 and the bending moment structure 14 are connected on end faces with water-swellable sealing pads 20.

[0045] The embedded steel bar connector 10 can improve the strength and stability of the connection point, ensuring that the exhaust and smoke exhaust pipe shaft structure remains firm when bearing the load generated by the smoke flow. The use of the embedded steel bar connector 10 can simplify the on-site construction process and reduce the workload of on-site welding or bolt connection. Connecting the boss mechanism and the main structure 13 or the bending moment structure 14 through the embedded steel bar connector 10 helps to form a unified structural system, thereby improving the reliability of the entire exhaust and smoke exhaust system. The water-swellable sealing gasket 20 will expand when it encounters moisture, thereby enhancing the sealing effect and automatically filling any tiny gaps that may exist, which can effectively prevent smoke or outside air from leaking or entering through the gaps in the connecting end faces, thereby ensuring the sealing and functionality of the exhaust and smoke exhaust system. Exemplarily, an enlarged head structure is provided at the two ends of the prefabricated transverse tube 1, which is connected to the cast-in-place concrete, so as to strengthen the bearing capacity of the joint and play a role in physical waterproofing and radiation protection. At the same time, a water-expanding elastic rubber sealing pad is provided inside, and a two-component polysulfide sealant can also be provided between the external gaps for double waterproofing measures. A steel bar connector is provided in the existing cast-in-place concrete. After installation and fixing, steel bars are inserted and special mortar is built to increase the connection and bonding force, so as to form an overall structure with certain shear resistance, bending resistance and tensile resistance. The connection between the bottom of the "inverted U"-shaped prefabricated transverse tube 1 and the main cast-in-place slab is achieved through a cast-in-place concrete baffle protruding from the bottom plate, that is, steel bar connectors are reserved at the bottom and longitudinal direction of the "inverted U"-shaped prefabricated reinforced concrete transverse tube (prefabricated transverse tube 1), and the connection and overall coordinated force and certain self-waterproofing ability are achieved through steel bars and post-grouting. At the same time, a water-expanding elastic rubber sealing pad waterproofing measure is provided on the side layout surface for further waterproofing. The "inverted U" shaped prefabricated cross tube 1 mainly bears the vertical pressure of civil defense on the top surface, and the lateral pressure is relatively small. At the same time, the cast-in-place concrete baffle is equivalent to strengthening the bottom connection. Therefore, the force of the "inverted U" shaped prefabricated reinforced concrete cross tube of the embodiment of the utility model meets the requirements.

[0046] Similarly, regarding the connection method of the prefabricated top cover 6, in the embodiment of the present utility model, as Figure 5As shown, a notch 15 is provided at the top of the longitudinal tube, and a protrusion 16 engaged with the notch 15 is provided at the prefabricated top cover 6. More specifically, a plurality of reserved steel bar holes 17 are provided on the prefabricated top cover 6, and each of the reserved steel bar holes 17 simultaneously penetrates the prefabricated top cover 6 and the protrusion 16. A plurality of embedded steel bar connectors 10 are also provided at the top of the longitudinal tube, and each of the embedded steel bar connectors 10 is connected to a single reserved steel bar hole 17. The design of the notch 15 and the protrusion 16 can achieve precise matching, ensuring that the connection between the top cover and the longitudinal tube is both firm and stable. This structure helps to form a good seal to prevent smoke or outside air from leaking or entering through the top of the longitudinal tube. The engaging design of the top cover can effectively prevent rainwater or other foreign matter from entering the interior of the pipe well, protecting the smoke exhaust system from the external environment. A number of reserved steel bar holes 17 arranged on the prefabricated top cover 6 allow steel bars to pass through the top cover and the protrusion 16, providing additional anchor points for the connection. The embedded steel bar connector 10 on the top of the longitudinal tube is connected to the reserved steel bar holes 17, providing a structural fixing method, thereby enhancing the connection strength between the top cover and the longitudinal tube. By using the reserved steel bar holes 17 and the embedded steel bar connector 10 in combination, the stability and wind load resistance of the entire exhaust and smoke exhaust pipe shaft structure can be improved.

[0047] For example, the prefabricated top cover 6 has a protruding concrete block, which is equivalent to a cover. At the same time, the reserved steel bar hole 17 is connected to the embedded steel bar connector 10 of the cast-in-place reinforced concrete vertical pipe 2 by steel bars, and grouting is built in the hole to increase the bonding force. This step can be implemented after the cast-in-place concrete of the vertical section solidifies. The protruding concrete block of the prefabricated top cover 6 and the corresponding cast-in-place concrete are both provided with water-expanding elastic rubber sealing pads, which can be sealed and waterproof when exposed to water. Of course, sealant can also be poured on the connection structure of each embedded steel bar connector 10.

[0048] For example, Figure 6 and Figure 7As shown, during construction, for step one, the cast-in-place section (cast-in-place reinforced concrete vertical pipe 2, first cast-in-place concrete baffle 8 and second cast-in-place concrete baffle 9) can be constructed first, and the formwork can be removed after the concrete solidifies, and the pre-embedded steel bar connector 10 and the elastic rubber sealing pad that expands when exposed to water are reserved in the cast-in-place concrete. Then the "inverted U"-shaped reinforced concrete horizontal pipe and the prefabricated reinforced concrete cover plate are hoisted into the corresponding pipeline area. Finally, the hole-to-hole operation is performed, and the steel bars are placed between the pre-embedded steel bar connectors, and grouting is performed one by one to form a connection. A two-component polysulfide sealant is set between the outer gaps of the outer layer; all gaps are grouted or filled and wrapped with fine stone concrete for physical blocking to form a finished product. In general, the pipe shaft structure provided by the utility model adopts cast-in-place concrete for the vertical shaft parts subjected to large forces and precast concrete for the horizontal pipe shaft parts subjected to relatively small forces according to the stress characteristics of the pipe shaft. The two combined methods solve the problems of difficulty in construction of complex pipe shafts using cast-in-place concrete and difficulty in removing the formwork. The connection between the precast concrete and the cast-in-place concrete is strengthened by end clips, and physical waterproofing is indirectly formed. At the same time, the concrete structure of the concrete pipe shaft can complete ventilation without the need to add additional metal ventilation ducts.
