Description

Technical Field

[0001] The present invention relates to a method for installing two adjacent smoke pipes on a building and a building. Background Art

[0002] Existing buildings include walls, floors and flue ducts. The floor is installed on the wall, and a reserved passage is provided on the floor. After the flue duct is inserted into the reserved passage, there is a filling gap between the flue duct and the floor. Concrete is filled into the filling gap to integrate the flue duct and the floor.

[0003] Since the filling gap runs through from top to bottom, before filling the concrete into the filling gap, it is necessary to block the lower opening of the filling gap.

[0004] Integrating the flue duct and the floor includes the following steps:

[0005] Step 1: A support rod pushes a load-bearing plate to abut against the lower surface of the floor to block the lower opening of the filling gap with the load-bearing plate;

[0006] Step 2: Fill the filling gap with concrete;

[0007] Step 3: After the concrete solidifies, remove the support rod;

[0008] Step 4: After the load-bearing plate loses the supporting force of the support rod, apply a force to the load-bearing plate to separate the load-bearing plate from the solidified concrete.

[0009] It can be seen from the above steps of "integrating the flue duct and the floor" that the existing "integrating the flue duct and the floor" has problems such as many processes, long time consumption, high labor cost, and difficulty in removing the load-bearing plate. Summary of the Invention

[0010] The problem to be solved by the present invention is to provide a method for installing two adjacent smoke pipes on a building and a building.

[0011] To solve the above problems, the present invention provides the following technical solutions:

[0012] The method for installing two adjacent smoke pipes on a building includes the following steps:

[0013] Step 1: Open a reserved passage on the floor, and the cross-section of the reserved passage > the cross-section of the smoke pipe;

[0014] Step 2: Set a floor bearing surface on the floor and a smoke pipe bearing surface on the smoke pipe. The floor bearing surface is inclined, and / or the smoke pipe bearing surface is inclined;

[0015] Step 3: At least a part of the lower smoke pipe among the adjacent smoke pipes is inserted into the reserved passage of a floor;

[0016] Step Four: Insert the load-bearing plate into the reserved channel in Step Three. After the load-bearing plate is inserted into the reserved channel in Step Three, the floor bearing surface and the smoke pipe bearing surface respectively support the load-bearing plate to prevent the load-bearing plate from overturning relative to the horizontal plane.

[0017] Step Five: Insert the upper smoke pipe among adjacent smoke pipes into the reserved channel in Step Four, and the upper smoke pipe among adjacent smoke pipes is stacked above the lower smoke pipe among adjacent smoke pipes.

[0018] Step Six: Fill the reserved channel with the filler. After the filler hardens, the two adjacent smoke pipes are both integrated with the floor.

[0019] When the floor bearing surface is inclined, the floor bearing surface is not parallel to the vertical direction; when the smoke pipe bearing surface is inclined, the smoke pipe bearing surface is not parallel to the vertical direction.

[0020] In the present invention, since the floor bearing surface supports the load-bearing plate, when the floor bearing surface is not parallel to the vertical plane, the floor bearing surface is arranged upward. Since the smoke pipe bearing surface supports the load-bearing plate, when the smoke pipe bearing surface is not parallel to the vertical plane, the smoke pipe bearing surface is arranged upward.

[0021] In the present invention, when the floor bearing surface is arranged upward, place the filler on the top wall of the load-bearing plate to apply the gravity of the filler to the load-bearing plate. After the filler applies gravity to the top wall of the load-bearing plate, the load-bearing plate applies a force to the floor bearing surface under the action of the gravity of the filler. Since the floor bearing surface is arranged upward, the floor bearing surface can support the load-bearing plate.

[0022] In the present invention, when the smoke pipe bearing surface is arranged upward, place the filler on the top wall of the load-bearing plate to apply the gravity of the filler to the load-bearing plate. After the filler applies gravity to the top wall of the load-bearing plate, the load-bearing plate applies a force to the floor bearing surface under the action of the gravity of the filler. Since the smoke pipe bearing surface is arranged upward, the smoke pipe bearing surface can support the load-bearing plate.

[0023] In the present invention, the floor bearing surface is not parallel to the vertical plane, the smoke pipe bearing surface is in contact with the load-bearing plate surface, and the floor bearing surface is not parallel to the smoke pipe bearing surface. This structure can enable the floor bearing surface and the smoke pipe bearing surface to respectively support the load-bearing plate to prevent the load-bearing plate from overturning relative to the horizontal plane.

[0024] Similarly, the smoke pipe bearing surface is not parallel to the vertical plane, the floor bearing surface is in contact with the load-bearing plate surface, and the floor bearing surface is not parallel to the smoke pipe bearing surface. This structure can enable the floor bearing surface and the smoke pipe bearing surface to respectively support the load-bearing plate to prevent the load-bearing plate from overturning relative to the horizontal plane.

[0025] Of course, the floor bearing surface is not parallel to the vertical surface, and the smoke pipe bearing surface is not parallel to the vertical surface. This structure can also support the load-bearing plate by the floor bearing surface and the smoke pipe bearing surface respectively to prevent the load-bearing plate from overturning relative to the horizontal plane.

[0026] In the present invention, after the load-bearing plate is inserted into the reserved channel in step three, the floor bearing surface and the smoke pipe bearing surface support the load-bearing plate respectively to prevent the load-bearing plate from overturning relative to the horizontal plane. When the floor bearing surface and the smoke pipe bearing surface support the load-bearing plate respectively to prevent the load-bearing plate from overturning relative to the horizontal plane, the direction and magnitude of the force exerted by the filler on the load-bearing plate change within a reasonable range (the meaning of "the direction and magnitude of the force exerted by the filler on the load-bearing plate change within a reasonable range" is that the gravity of the filler cannot cause the load-bearing plate to break), which will not drive the load-bearing plate to overturn relative to the horizontal plane. With such a design, when it is ensured that the load-bearing plate can bear the weight of the filler, the load-bearing plate can work continuously and stably.

[0027] In the present invention, the filler is filled into the reserved channel. After the filler hardens, two adjacent smoke pipes are integrally connected to the floor. At this time, the load-bearing plate is also retained in the reserved channel. With such a design, on the premise of ensuring the reliable operation of the load-bearing plate, steps one, three, and four in the prior art are omitted in the present invention. Among them, step one in the prior art is that the support rod pushes the load-bearing plate to abut against the lower surface of the floor to realize the load-bearing plate blocking the lower opening of the filling gap, step three in the prior art is to remove the support rod after the concrete solidifies, and step four in the prior art is to apply a force to the load-bearing plate to separate the load-bearing plate from the solidified concrete.

[0028] When steps one, three, and four in the prior art are omitted in the present invention, the "smoke pipe is integrally connected to the floor" has the advantages of fewer processes, shorter time consumption, lower labor cost, and no need to remove the load-bearing plate.

[0029] Further, when the floor bearing surface is not parallel to the vertical surface, the floor bearing surface is parallel to the horizontal plane, or the floor bearing surface inclines from top to bottom towards the direction of the smoke pipe; when the smoke pipe bearing surface is not parallel to the vertical surface, the smoke pipe bearing surface is parallel to the horizontal plane, or the smoke pipe bearing surface inclines from top to bottom towards the inner wall of the floor where the reserved channel is located. With such a design, the reliability of the floor bearing surface is increased, and the reliability of the smoke pipe bearing surface is increased.

[0030] Further, the floor is formed by demolding the concrete hardened after being poured into the formwork. The formwork includes a bottom plate and embedded parts. The bottom plate is provided with a reserved hole. The embedded parts include side plates that incline from top to bottom towards the direction of the reserved hole. At least part of the side plates are arranged above the bottom plate. The floor bearing surface is formed by demolding the concrete that adheres to the side plates after hardening.

[0031] The floor bearing surface is directly formed on the floor slab, which can effectively reduce the subsequent step of opening the floor bearing surface on the floor slab. With such a design, the cost of opening the floor bearing surface is reduced.

[0032] Furthermore, the embedded part is detachably arranged on the bottom plate. With such a design, the embedded part and the bottom plate can be reused.

[0033] Furthermore, the floor bearing surface is formed after the floor slab is cut. With such a design, the existing floor slab can be renovated to simplify the step of "connecting the smoke pipe and the floor slab as a whole".

[0034] Furthermore, a first mating surface and a second mating surface are provided on the side wall of the load-bearing plate. The first mating surface and the second mating surface are not parallel. The first mating surface abuts against the smoke pipe bearing surface of the smoke pipe located below, and the second mating surface abuts against the floor bearing surface. When the first mating surface abuts against the smoke pipe bearing surface of the smoke pipe located below and the second mating surface abuts against the floor bearing surface, the top wall of the load-bearing plate is not perpendicular to the horizontal plane.

[0035] When the first mating surface and the second mating surface are not parallel, the smoke pipe bearing surface and the floor bearing surface are not parallel, so as to form an angle not equal to 0° between the smoke pipe bearing surface and the floor bearing surface. With such a design, the load-bearing plate will not be able to slide along the smoke pipe bearing surface and the floor bearing surface.

[0036] In addition, the first mating surface abuts against the smoke pipe bearing surface of the smoke pipe located below, and the second mating surface abuts against the floor bearing surface. Through the surface contact between the smoke pipe bearing surface and the floor bearing surface and the load-bearing plate respectively, the resistance of the load-bearing plate to slide relative to the smoke pipe and the resistance of the load-bearing plate to slide relative to the floor are increased.

[0037] Furthermore, in step five, when the smoke pipe located above is stacked on the smoke pipe located below, a filler is filled between the smoke pipe located above and the smoke pipe located below. With such a design, the connection strength between adjacent smoke pipes is increased.

[0038] A building includes at least two smoke pipe units. Each smoke pipe unit includes a floor slab, a load-bearing plate and a smoke pipe. The volume of the load-bearing plate < the volume of the smoke pipe. A reserved channel is provided on the floor slab. The cross-section of the reserved channel > the cross-section of the smoke pipe. The smoke pipes of adjacent smoke pipe units are stacked. Two stacked smoke pipes are inserted into a reserved channel. A floor bearing surface is provided on the floor slab. A smoke pipe bearing surface is provided on the smoke pipe. The load-bearing plate is inserted into the reserved channel and abuts against the floor bearing surface and the smoke pipe bearing surface;

[0039] Wherein, the floor bearing surface is not parallel to the vertical plane, and / or the smoke pipe bearing surface is not parallel to the vertical plane.

[0040] Further, an inclined surface is provided on the wall of the reserved channel, and the inclined surface inclines towards the direction of the smoke pipe from top to bottom, and the floor bearing surface is the inclined surface; or, steps are provided on the floor, and the steps include a side step surface and a lower step surface, the side step surface is connected to the wall of the reserved channel through the lower step surface, and the floor bearing surface is the lower step surface; or, the top wall of the floor is connected to the wall of the reserved channel, and the floor bearing surface is the top wall of the floor; or, the top wall of the floor is connected to the wall of the reserved channel, an inclined surface is provided on the wall of the reserved channel, and the inclined surface inclines towards the direction of the smoke pipe from top to bottom, and the floor bearing surface includes the top wall of the floor and the inclined surface.

[0041] Further, when the floor bearing surface is not parallel to the vertical plane, the floor bearing surface is parallel to the horizontal plane, or the floor bearing surface inclines towards the direction of the smoke pipe from top to bottom; when the smoke pipe bearing surface is not parallel to the vertical plane, the smoke pipe bearing surface is parallel to the horizontal plane, or the smoke pipe bearing surface inclines towards the direction of the wall of the floor where the reserved channel is located from top to bottom.

[0042] Further, an inclined surface is provided on the wall of the reserved channel, and the inclined surface inclines towards the direction of the smoke pipe from top to bottom, and the floor bearing surface includes the inclined surface. With such a design, the contact area between the reserved channel and the bearing plate is increased through the inclined surface.

[0043] Further, the top wall of the floor is connected to the wall of the reserved channel, and the floor bearing surface includes the top wall of the floor. With such a design, the existing structure of the floor is utilized to increase the connection strength between the bearing plate and the floor.

[0044] Further, when the floor bearing surface includes the inclined surface, the bearing plate abuts against the inclined surface; when the floor bearing surface includes the top wall of the floor, the bearing plate abuts against the top wall; when the floor bearing surface includes the inclined surface and the top wall of the floor, the bearing plate abuts against the inclined surface and the top wall of the floor.

[0045] Further, the bearing plate abuts against the side wall of the smoke pipe, and / or the bearing plate abuts against the top wall of the smoke pipe. With such a design, the existing structure of the smoke pipe is utilized to increase the connection strength between the bearing plate and the smoke pipe.

[0046] Further, a first mating surface and a second mating surface are provided on the side wall of the bearing plate, the first mating surface is not parallel to the second mating surface, the first mating surface abuts against the smoke pipe bearing surface, the second mating surface abuts against the floor bearing surface, and when the first mating surface abuts against the smoke pipe bearing surface and the second mating surface abuts against the floor bearing surface, the top wall of the bearing plate is not perpendicular to the horizontal plane.

[0047] Further, the load-bearing plate includes a plate body and a first hook. The plate body abuts against the floor bearing surface and the smoke pipe bearing surface, and the first hook abuts against the floor bearing surface; or, the load-bearing plate includes a plate body and a second hook. The plate body abuts against the floor bearing surface and the smoke pipe bearing surface, and the second hook abuts against the smoke pipe bearing surface; or, the load-bearing plate includes a plate body, a first hook and a second hook. The plate body abuts against the floor bearing surface and the smoke pipe bearing surface, the first hook abuts against the floor bearing surface, and the second hook abuts against the smoke pipe bearing surface.

[0048] Further, the load-bearing plate includes at least two splicing plates. Adjacent splicing plates are joined. Each splicing plate is inserted into the reserved channel and abuts against the floor bearing surface and the smoke pipe bearing surface. Designed in this way, the installation difficulty of the load-bearing plate is reduced.

[0049] Further, there are steps on the floor. The steps include a side step surface and a lower step surface. The side step surface is connected to the wall of the reserved channel through the lower step surface, and the floor bearing surface is the lower step surface.

[0050] Further, in step five, when the upper smoke pipe is stacked on the lower smoke pipe, a support rod is clamped between the two smoke pipes, and the support rod is arranged on the floor. The support rod is used to support the upper smoke pipe. Therefore, when the support rod is arranged on the floor, the upper smoke pipe can be installed first, and then the lower smoke pipe can be installed. Description of the Drawings

[0063] The technical solutions of the embodiments of the present invention will be explained and illustrated below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0064] See Figure 1 and Figure 2 , the installation method of two adjacent smoke pipes on a building includes the following steps:

[0065] Step 1: Open a reserved channel 111 on the floor slab 11, and the cross-section of the reserved channel 111 > the cross-section of the smoke pipe 12. Among them, the cross-sectional area of the reserved channel 111 is the area dimension of the reserved channel 111 in the horizontal direction, and the cross-section of the smoke pipe 12 is the area dimension of the smoke pipe 12 in the horizontal direction;

[0066] Step 2: Set a floor slab bearing surface 112 on the floor slab 11 and a smoke pipe bearing surface 121 on the smoke pipe 12. The floor slab bearing surface 112 is inclined, and / or the smoke pipe bearing surface 121 is inclined;

[0067] Step 3: At least a part of the lower smoke pipe 12 among the adjacent smoke pipes 12 is inserted into the reserved channel 111 of a floor slab 11;

[0068] Step 4: Insert the load-bearing plate 13 into the reserved channel 111 in Step 3. After the load-bearing plate 13 is inserted into the reserved channel 111 in Step 3, the floor slab bearing surface 112 and the smoke pipe bearing surface 121 respectively support the load-bearing plate 13 to prevent the load-bearing plate 13 from flipping relative to the horizontal plane;

[0069] Step Five, the upper flue pipe 12 among adjacent flue pipes 12 is inserted into the reserved channel 111 in Step Four, and the upper flue pipe 12 among adjacent flue pipes 12 is stacked above the lower flue pipe 12 among adjacent flue pipes 12;

[0070] Step Six, a filler (not marked) is filled into the reserved channel 111. After the filler hardens, the two adjacent flue pipes 12 are integrally connected to the floor slab 11.

[0071] It should be noted that "the floor slab bearing surface 112 is not parallel to the vertical plane, and / or the flue pipe bearing surface 121 is not parallel to the vertical plane" includes three meanings: 1. The floor slab bearing surface 112 is not parallel to the vertical plane, and the flue pipe bearing surface 121 is parallel to the vertical plane, as shown in Figure 1 and Figure 2 ; 2. The floor slab bearing surface 112 is parallel to the vertical plane, and the flue pipe bearing surface 121 is not parallel to the vertical plane; 3. The floor slab bearing surface 112 is not parallel to the vertical plane, and the flue pipe bearing surface 121 is not parallel to the vertical plane.

[0072] When the floor slab bearing surface 112 is inclined, the floor slab bearing surface 112 is not parallel to the vertical direction; when the flue pipe bearing surface 121 is inclined, the flue pipe bearing surface 121 is not parallel to the vertical direction.

[0073] In the present invention, the filler is used to integrally connect the flue pipe 12 and the floor slab 11. Preferred fillers include, but are not limited to, concrete and cement. Of course, the filler can also be other gelling materials.

[0074] In the present invention, since the floor slab bearing surface 112 supports the load-bearing plate 13, when the floor slab bearing surface 112 is not parallel to the vertical plane, the floor slab bearing surface 112 faces upward. Since the flue pipe bearing surface 121 supports the load-bearing plate 13, when the flue pipe bearing surface 121 is not parallel to the vertical plane, the flue pipe bearing surface 121 faces upward.

[0075] Refer to Figure 1 and Figure 2 , when the floor slab bearing surface 112 faces upward, the filler is placed on the top wall 133 of the load-bearing plate 13 to apply the gravity of the filler to the load-bearing plate 13. After the filler applies gravity to the top wall 133 of the load-bearing plate 13, the load-bearing plate 13 applies a force to the floor slab bearing surface 112 under the action of the gravity of the filler. Since the floor slab bearing surface 112 faces upward, the floor slab bearing surface 112 can support the load-bearing plate 13. In other embodiments of the present invention, when the flue pipe bearing surface faces upward, the filler is placed on the top wall of the load-bearing plate to apply the gravity of the filler to the load-bearing plate. After the filler applies gravity to the top wall of the load-bearing plate, the load-bearing plate applies a force to the floor slab bearing surface under the action of the gravity of the filler. Since the flue pipe bearing surface faces upward, the flue pipe bearing surface can support the load-bearing plate.

[0076] From Figure 2 It can be seen that when the floor bearing surface 112 is arranged upward to support the load-bearing plate 13, the smoke pipe bearing surface 121 is parallel to the vertical plane to support the load-bearing plate 13.

[0077] In the present invention, the floor bearing surface 112 is not parallel to the vertical plane, the smoke pipe bearing surface 121 is in surface contact with the load-bearing plate 13, and the floor bearing surface 112 is not parallel to the smoke pipe bearing surface 121. This structure can enable the floor bearing surface 112 and the smoke pipe bearing surface 121 to respectively support the load-bearing plate 13 to prevent the load-bearing plate 13 from overturning relative to the horizontal plane.

[0078] Similarly, the smoke pipe bearing surface 121 is not parallel to the vertical plane, the floor bearing surface 112 is in surface contact with the load-bearing plate 13, and the floor bearing surface 112 is not parallel to the smoke pipe bearing surface 121. This structure can enable the floor bearing surface 112 and the smoke pipe bearing surface 121 to respectively support the load-bearing plate 13 to prevent the load-bearing plate 13 from overturning relative to the horizontal plane.

[0079] Certainly, the floor bearing surface 112 is not parallel to the vertical plane, and the smoke pipe bearing surface 121 is not parallel to the vertical plane. This structure can also enable the floor bearing surface 112 and the smoke pipe bearing surface 121 to respectively support the load-bearing plate 13 to prevent the load-bearing plate 13 from overturning relative to the horizontal plane.

[0080] In the present invention, after the load-bearing plate 13 is inserted into the reserved channel 111 in step three, the floor bearing surface 112 and the smoke pipe bearing surface 121 respectively support the load-bearing plate 13 to prevent the load-bearing plate 13 from overturning relative to the horizontal plane. When the floor bearing surface 112 and the smoke pipe bearing surface 121 respectively support the load-bearing plate 13 to prevent the load-bearing plate 13 from overturning relative to the horizontal plane, the direction and magnitude of the force exerted by the filler on the load-bearing plate 13 change within a reasonable range (the meaning of "the direction and magnitude of the force exerted by the filler on the load-bearing plate 13 change within a reasonable range" is: the gravity of the filler cannot cause the load-bearing plate 13 to break), and it will not drive the load-bearing plate 13 to overturn relative to the horizontal plane. With such a design, when ensuring that the load-bearing plate 13 can bear the weight of the filler, the load-bearing plate 13 can work continuously and stably.

[0081] In the present invention, a filler is filled into the reserved channel 111. After the filler hardens, two adjacent smoke pipes 12 are integrally connected to the floor slab 11. At this time, the load-bearing plate 13 is also retained in the reserved channel 111. With such a design, on the premise of ensuring the reliable operation of the load-bearing plate 13, steps 1, 3, and 4 in the prior art are omitted. Among them, step 1 in the prior art is that the support rod pushes the load-bearing plate to abut against the lower surface of the floor slab to seal the lower opening of the filling gap by the load-bearing plate, step 3 in the prior art is to remove the support rod after the concrete solidifies, and step 4 in the prior art is to apply a force to the load-bearing plate to separate the load-bearing plate from the solidified concrete.

[0082] When steps 1, 3, and 4 in the prior art are omitted in the present invention, "the smoke pipe 12 is integrally connected to the floor slab 11" has the advantages of fewer processes, shorter time consumption, lower labor costs, and no need to remove the load-bearing plate.

[0083] In addition, by retaining the load-bearing plate 13 in the reserved channel 111, the load-bearing plate 13 also plays the roles of supporting the filler, protecting the filler, and closing the lower opening of the reserved channel 111.

[0084] In this embodiment, when the floor slab bearing surface 112 is not parallel to the vertical surface, the floor slab bearing surface 112 is parallel to the horizontal plane, or the floor slab bearing surface 112 is inclined downward from top to bottom toward the smoke pipe 12; when the smoke pipe bearing surface 121 is not parallel to the vertical surface, the smoke pipe bearing surface 121 is parallel to the horizontal plane, or the smoke pipe bearing surface 121 is inclined downward from top to bottom toward the inner wall of the floor slab 11 where the reserved channel 111 is located.

[0085] See Figure 1 and Figure 3 , the floor slab 11 is formed by demolding after the concrete poured into the formwork 10 hardens. The formwork 10 includes a bottom plate 100 and a pre-embedded part 200. Among them, the bottom plate 100 coincides with the bottom wall of the floor slab 11, the outer surface of the periphery of the pre-embedded part 200 coincides with the wall of the reserved channel 111. A reserved hole (not marked) is provided on the bottom plate 100. The pre-embedded part 200 includes a side plate 2001 inclined downward from top to bottom toward the reserved hole. At least part of the side plate 2001 is located above the bottom plate 100. The floor slab bearing surface 112 is formed by demolding after the concrete attached to the side plate 2001 hardens.

[0086] When the floor slab bearing surface 112 is directly formed on the floor slab 11, the subsequent step of opening the floor slab bearing surface 112 on the floor slab 11 can be effectively omitted, so as to reduce the opening cost of the floor slab bearing surface 112.

[0087] Preferably, the pre-embedded part 200 is detachably arranged on the bottom plate 100 to enable the pre-embedded part 200 and the bottom plate 100 to be reused.

[0088] For an existing building, the floor bearing surface 112 is formed by cutting the floor slab 11. Such a design can transform the existing floor slab 11 to simplify the step of "integrating the smoke pipe 12 with the floor slab 11".

[0089] See Figure 2 , on the side wall of the load-bearing plate 13, there are a first mating surface 132 and a second mating surface 131. The first mating surface 132 and the second mating surface 131 are not parallel. The first mating surface 132 abuts against the smoke pipe bearing surface 121 of the smoke pipe 12 below, and the second mating surface 131 abuts against the floor bearing surface 112. When the first mating surface 132 abuts against the smoke pipe bearing surface 121 of the smoke pipe 12 below and the second mating surface 131 abuts against the floor bearing surface 112, the top wall 133 of the load-bearing plate 13 is not perpendicular to the horizontal plane.

[0090] When the first mating surface 132 and the second mating surface 131 are not parallel, the smoke pipe bearing surface 121 and the floor bearing surface 112 are not parallel, so as to form an angle not equal to 0° between the smoke pipe bearing surface 121 and the floor bearing surface 112. With such a design, the load-bearing plate 13 cannot slide along the smoke pipe bearing surface 121 and the floor bearing surface 112.

[0091] In addition, the first mating surface 132 abuts against the smoke pipe bearing surface 121 of the smoke pipe 12 below, and the second mating surface 131 abuts against the floor bearing surface 112. Through the surface contact between the smoke pipe bearing surface 121 and the floor bearing surface 112 and the load-bearing plate 13 respectively, the resistance to the relative sliding of the load-bearing plate 13 with respect to the smoke pipe 12 and the resistance to the relative sliding of the load-bearing plate 13 with respect to the floor slab 11 are increased.

[0092] In step five of this embodiment, when the upper smoke pipe 12 is stacked above the lower smoke pipe 12, a filler is filled between the upper smoke pipe 12 and the lower smoke pipe 12 to increase the connection strength between adjacent smoke pipes 12.

[0093] See Figure 1 and Figure 2 , the building includes at least two smoke pipe units 1. Each smoke pipe unit 1 includes a floor slab 11, a load-bearing plate 13, and a smoke pipe 12. The volume of the load-bearing plate 13 < the volume of the smoke pipe 12. There is a reserved channel 111 on the floor slab 11. The cross-section of the reserved channel 111 > the cross-section of the smoke pipe 12. The smoke pipes 12 of adjacent smoke pipe units 1 are stacked. Two stacked smoke pipes 12 are inserted into a reserved channel 111. There is a floor bearing surface on the floor slab, and there is a smoke pipe bearing surface on the smoke pipe. The load-bearing plate is inserted into the reserved channel and abuts against the floor bearing surface and the smoke pipe bearing surface;

[0094] Wherein, the floor bearing surface is not parallel to the vertical plane, and / or the smoke pipe bearing surface is not parallel to the vertical plane.

[0095] When two stacked smoke pipes 12 are inserted into a reserved channel 111, the connection between the two stacked smoke pipes 12 is located above the load-bearing plate 13. This structure can effectively ensure that the filler seals the connection between the two stacked smoke pipes 12.

[0096] In step five, when the upper smoke pipe 12 is stacked on top of the lower smoke pipe 12, a support rod 3 is clamped between the two smoke pipes. The support rod 3 is provided on the floor slab 11. The support rod 3 is used to support the upper smoke pipe 12. Since the support rod 3 is used to support the upper smoke pipe 12, when the support rod 3 is provided on the floor slab 11, the upper smoke pipe 12 can be installed first, and then the lower smoke pipe 12 can be installed.

[0097] In this embodiment, an installation groove 1121 is provided on the floor slab 11, and the support rod 3 is placed in the installation groove 1121.

[0098] In this embodiment, there are various setting methods for the floor slab bearing surface 112: 1. An inclined surface is provided on the wall of the reserved channel 111, and the inclined surface inclines towards the smoke pipe 12 from top to bottom, and the floor slab bearing surface 112 is the inclined surface; 2. Steps are provided on the floor slab 11, and the steps include a side step surface and a lower step surface. The side step surface is connected to the wall of the reserved channel 111 through the lower step surface, and the floor slab bearing surface 112 is the lower step surface; 3. The top wall of the floor slab 11 is connected to the wall of the reserved channel 111, and the floor slab bearing surface 112 is the top wall of the floor slab 11; 4. The top wall of the floor slab 11 is connected to the wall of the reserved channel 111, and an inclined surface is provided on the wall of the reserved channel 111, and the inclined surface inclines towards the smoke pipe 12 from top to bottom, and the floor slab bearing surface 112 includes the top wall of the floor slab 11 and the inclined surface.

[0099] In the present invention, when the floor slab bearing surface 112 is not parallel to the vertical plane, the floor slab bearing surface 112 is parallel to the horizontal plane, or the floor slab bearing surface 112 inclines towards the smoke pipe 12 from top to bottom; when the smoke pipe bearing surface 121 is not parallel to the vertical plane, the smoke pipe bearing surface 121 is parallel to the horizontal plane, or the smoke pipe bearing surface 121 inclines towards the wall of the floor slab 11 located in the reserved channel 111 from top to bottom.

[0100] In this embodiment, there are the following four preferred solutions for the floor bearing surface 112: 1. An inclined surface is provided on the wall of the reserved passage 111, and the inclined surface inclines from top to bottom towards the direction of the smoke pipe 12. The floor bearing surface 112 includes the inclined surface. When the floor bearing surface 112 includes the inclined surface, the load-bearing plate 13 abuts against the inclined surface. In this solution, the reserved passage 111 increases the contact area with the load-bearing plate 13 through the inclined surface; 2. The top wall of the floor 11 is connected to the wall of the reserved passage 111, and the floor bearing surface 112 includes the top wall of the floor 11. When the floor bearing surface 112 includes the top wall of the floor 11, the load-bearing plate 13 abuts against the top wall. In this solution, the existing structure of the floor 11 is utilized to increase the connection strength between the load-bearing plate 13 and the floor 11; 3. An inclined surface is provided on the wall of the reserved passage 111, and the inclined surface inclines from top to bottom towards the direction of the smoke pipe 12. The top wall of the floor 11 is connected to the wall of the reserved passage 111, and the floor bearing surface 112 includes the top wall of the floor 11 and the inclined surface. From Figure 4 It can be seen that when the floor bearing surface 112 includes the inclined surface and the top wall of the floor 11, the load-bearing plate 13 abuts against the inclined surface and the top wall of the floor 11; 4. Steps are provided on the floor 11. The steps include a side step surface and a lower step surface. The side step surface is connected to the wall of the reserved passage 111 through the lower step surface, and the floor bearing surface 112 is the lower step surface.

[0101] See Figure 4 , when the load-bearing plate 13 abuts against the inclined surface and the top wall of the floor 11, the load-bearing plate 13 includes a plate body, a first hook 4 and a second hook 5. The plate body abuts against the floor bearing surface 112 (the floor bearing surface 112 is the inclined surface) and the smoke pipe bearing surface 121 (the smoke pipe bearing surface 121 is the side wall of the smoke pipe 12), the first hook 4 abuts against the floor bearing surface 112 (the floor bearing surface 112 is the top wall of the floor 11), and the second hook 5 abuts against the smoke pipe bearing surface 121 (the smoke pipe bearing surface 121 is the top wall of the smoke pipe 12). In other embodiments of the present invention, the load-bearing plate includes a plate body and a first hook. The plate body abuts against the floor bearing surface and the smoke pipe bearing surface, and the first hook abuts against the floor bearing surface; or, the load-bearing plate includes a plate body and a second hook. The plate body abuts against the floor bearing surface and the smoke pipe bearing surface, and the second hook abuts against the smoke pipe bearing surface.

[0102] Preferably, the first hook 4 and the second hook 5 are integrally formed. In other embodiments of the present invention, the first hook 4 and the second hook 5 are independently provided.

[0103] From Figure 4 It can be seen that the load-bearing plate 13 abuts against the side wall of the smoke pipe 12, and the load-bearing plate 13 abuts against the top wall of the smoke pipe 12; from Figure 1 It can be seen that the load-bearing plate 13 abuts against the side wall of the smoke pipe 12. In other embodiments of the present invention, the load-bearing plate abuts against the top wall of the smoke pipe.

[0104] When the load-bearing plate 13 abuts against the side wall of the smoke pipe 12, the smoke pipe receiving surface 121 can be parallel to the horizontal plane. From Figure 5 As can be seen, the smoke pipe 12 includes a support member 120, and a smoke pipe receiving surface 121 is provided on the support member 120. The smoke pipe receiving surface 121 faces upward and is parallel to the horizontal plane.

[0105] See Figure 1 , in this embodiment, the load-bearing plate 13 is integrally formed. A first mating surface 132 and a second mating surface 131 are provided on the side wall of the load-bearing plate 13. The first mating surface 132 and the second mating surface 131 are not parallel. The first mating surface 132 abuts against the smoke pipe receiving surface 121, and the second mating surface 131 abuts against the floor receiving surface 112. When the first mating surface 132 abuts against the smoke pipe receiving surface 121 and the second mating surface 131 abuts against the floor receiving surface 112, the top wall 133 of the load-bearing plate 13 is not perpendicular to the horizontal plane.

[0106] Preferably, when the first mating surface 132 abuts against the side wall of the lower smoke pipe 12 and the second mating surface 131 abuts against the inclined section, the top wall 133 of the load-bearing plate 13 is parallel to the horizontal plane.

[0107] Preferably, the load-bearing plate 13 includes at least two splicing plates. Adjacent splicing plates are joined. Each splicing plate is inserted into the reserved channel 111 and abuts against the floor receiving surface 112 and the smoke pipe receiving surface 121. From Figure 6 As can be seen, the load-bearing plate 13 includes a first splicing plate 1301 and a second splicing plate 1302. The first splicing plate 1301 and the second splicing plate 1302 are joined. The first splicing plate 1301 is inserted into the reserved channel 111 and abuts against the floor receiving surface 112 and the smoke pipe receiving surface 121. The second splicing plate 1302 is inserted into the reserved channel 111 and abuts against the floor receiving surface 112 and the smoke pipe receiving surface 121.

[0108] From Figure 1 As can be seen, when adjacent smoke pipes 12 are joined end to end, the joint of the adjacent smoke pipes 12 corresponds to the inclined section, and a load-bearing plate 13 is clamped between the lower smoke pipe 12 of the adjacent smoke pipes 12 and the inclined section. A third filling groove (not marked) for accommodating the filler is formed by the side wall of the smoke pipe 12, the load-bearing plate 13 and the inclined section.

[0109] In this embodiment, the installation method of adjacent two smoke pipes on the building includes the following steps:

[0110] Step 1, a reserved channel 111 (the reserved channel 111 can also be called a reserved hole) is opened on the floor 11, which can be obtained by the in-situ casting and embedding method of the floor or by cutting the floor, such as Figure 7 , Figure 8 and Figure 9 shown.

[0111] Preferably, a pre-embedded hole mold embedded part 200 is adopted, and a reserved channel 111 is obtained after removal.

[0112] Furthermore, the obtained reserved channel 111 has an inclined mouth shape that is wider at the top and narrower at the bottom, and each adjacent floor bearing surface 112 has an upward-opening installation groove 1121.

[0113] Step 2: Place the lower flue pipe among the adjacent flue pipes 12 (the flue pipe 12 can also be called an exhaust duct) in the middle of the reserved channel 111.

[0114] Step 3: Place a load-bearing plate 13 (the load-bearing plate 13 can also be called a suspended formwork member) between the reserved channel 111 and the flue pipe 12, as Figure 10 shown.

[0115] Preferably, the load-bearing plate 13 is integrally formed, and the cross-sectional shape thereof matches the cross-sectional shape of the gap left between the outer contours of the reserved channel 111 and the flue pipe 12.

[0116] Furthermore, the load-bearing plate 13 not only extrudes and initially stabilizes the flue pipe 12, but also seals the gap between the reserved channel 111 and the outer contour of the flue pipe 12.

[0117] Step 4: Apply caulking clay at the cross-section of the flue pipe 12 to be butt-jointed and at the gap between the outer contour of the flue pipe 12 close to the reserved channel 111, and then place the upper flue pipe 12 of the adjacent flue pipe for butt-jointing.

[0118] Furthermore, a support rod 3 can be placed in the installation groove 1121. The support rod 3 is preferably a bearing steel bar, and then the upper flue pipe 12 of the adjacent flue pipe is placed for butt-jointing. At this time, the load of the upper flue pipe 12 is transferred from the lower flue pipe to the bearing steel bar and the floor 11 for bearing, as Figure 10 and Figure 11 shown.

[0119] Step 5: Pour a filler on the load-bearing plate 13.

[0120] Preferably, the filler is selected as C20 fine aggregate concrete, which is poured and tamped tightly to bury the butt-joint of the flue pipe 12 until it is flush with the floor 11.

[0121] Step 6: After the filler hardens, the butt-joint of the two adjacent flue pipes 12, the load-bearing plate 13, the bearing steel bar 114, the reserved channel 111 and the floor 11 are connected into one body, as Figure 12 shown.

[0122] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
