Smoke flue installation structure and construction method thereof

Abstract

The present application relates to the technical field of building construction, and discloses a smoke flue mounting structure and a construction method thereof. The smoke flue mounting structure comprises a supporting piece and a supporting plate. One end of the supporting piece is arranged in a reserved hole of a floor, and the other end can abut against the bottom surface of the floor. The top end of the smoke flue below the floor can abut against the supporting piece. The supporting plate is arranged on the top surface of the floor and connected with the supporting piece. The bottom end of the smoke flue above the floor can abut against the supporting plate. The presence of the supporting piece and the supporting plate enables the smoke flue to be vertically arranged between two adjacent floors, thereby ensuring the installation quality of the smoke flue. The presence of the supporting plate enables the dead load of the smoke flue to be transmitted to the corresponding floor through the supporting plate, thereby achieving the unloading of the smoke flue. Since the supporting piece is arranged in the reserved hole and the lower end of the supporting piece can abut against the bottom surface of the floor, after the smoke flue is placed, only the concrete needs to be poured between the supporting piece and the hole wall of the reserved hole, without the need for formwork, thereby simplifying the construction steps and effectively shortening the construction period.

Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a flue gas duct installation structure and its construction method. Background Technology

[0002] Currently, kitchens, bathrooms, and other spaces all have smoke and air duct structures, which can effectively remove smoke and odors.

[0003] In traditional flue gas duct construction, pre-reserved holes of corresponding sizes are usually made during the pouring of the main floor slab according to the design drawings. The size of the pre-reserved holes is generally larger than the size of the flue gas duct. When installing the flue gas duct later, it is hoisted from the upper floor to the corresponding installation floor through the pre-reserved holes. It is also necessary to install steel bars at the pre-reserved holes, then place the flue gas duct, hoist the formwork at the flue gas duct interface, pour the flue gas duct at the root of the flue gas duct, and remove the formwork, etc., which are many construction procedures. The construction steps are complicated and the construction period is long.

[0004] Furthermore, the aforementioned construction method makes it difficult to control the verticality of the flue gas ducts during installation, which can easily lead to gaps between floors after installation, preventing the entire flue gas duct from closing properly and compromising installation quality. Moreover, since flue gas ducts are often used in kitchens and bathrooms, poor pouring quality during formwork installation can cause water leakage at the duct joints, potentially leading to floor slab seepage and posing a quality hazard.

[0005] Therefore, there is an urgent need for a flue gas duct installation structure and its construction method to solve the above problems. Summary of the Invention

[0006] Based on the above problems, the purpose of this invention is to provide a flue gas duct installation structure and its construction method, which can ensure the installation quality of the flue gas duct, avoid leakage problems, and has simple construction steps and high construction efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] On the one hand, a flue gas duct installation structure is provided, including:

[0009] The support member has a reserved hole in the floor slab. One end of the support member passes through the reserved hole, and the other end can abut against the bottom surface of the floor slab. The top of the flue gas duct below the floor slab can abut against the support member.

[0010] A support plate is disposed on the top surface of the floor slab and connected to the support member. The bottom end of the smoke duct above the floor slab can abut against the support plate.

[0011] As a preferred embodiment of the flue gas duct installation structure of the present invention, the support member includes a connected cylindrical body and a limiting plate. The cylindrical body passes through the reserved hole, the limiting plate can fit against the bottom surface of the floor slab, the top end of the flue gas duct abuts against the limiting plate, one end of the support plate rests on the floor slab, and the other end rests on the cylindrical body and is connected to the limiting plate.

[0012] As a preferred embodiment of the flue gas duct installation structure of the present invention, the flue gas duct installation structure further includes a connector, a gap is left between the cylinder and the wall of the reserved hole, and the connector passes through the support plate and extends into the gap to connect with the limiting plate.

[0013] As a preferred embodiment of the flue gas duct installation structure of the present invention, a nut seat is provided in the gap on the limiting plate, and the connecting member includes a fixing rod with an external thread. The fixing rod is threadedly connected to the nut seat through the external thread.

[0014] As a preferred embodiment of the flue gas duct installation structure of the present invention, the connector further includes a locking member disposed on the fixing rod. The locking member is located on the side of the support plate facing away from the limiting plate, and the locking member can press the support plate tightly onto the floor slab.

[0015] As a preferred embodiment of the flue gas duct installation structure of the present invention, a plurality of support plates are provided, and the plurality of support plates are distributed at circumferential intervals along the reserved holes, and each support plate is connected to the limiting plate through the connector.

[0016] As a preferred embodiment of the flue gas duct installation structure of the present invention, the flue gas duct installation structure further includes a concrete filling layer, which fills the space between the outer wall of the cylinder and the wall of the reserved hole.

[0017] As a preferred embodiment of the flue gas duct installation structure of the present invention, the outer wall of the cylinder and the side of the limiting plate facing the floor slab are both provided with concave and convex structures to form a rough surface.

[0018] As a preferred embodiment of the flue gas duct installation structure of the present invention, both the support member and the support plate are made of stainless steel.

[0019] On the other hand, a method for constructing a flue gas duct is provided, which adopts the flue gas duct installation structure described above, and includes the following steps:

[0020] The support member is installed in the reserved hole in the two adjacent floor slabs, and the support plate on the corresponding floor slab is connected and fixed to the support member;

[0021] The smoke duct is installed between two adjacent floor slabs, with the bottom end of the smoke duct abutting against the support plate at the reserved hole in the lower floor slab, and the top end of the smoke duct abutting against the support member at the reserved hole in the upper floor slab, until the smoke ducts of all floors are installed.

[0022] The beneficial effects of this invention are as follows:

[0023] The flue gas duct installation structure and construction method provided by this invention involve first installing support members and support plates at pre-drilled holes in two adjacent floor slabs. Then, the flue gas duct is placed between the two adjacent floor slabs, with its top end abutting against the support member at the pre-drilled hole in the upper floor slab and its bottom end abutting against the support plate at the pre-drilled hole in the lower floor slab. Both ends of the flue gas duct are connected to the pre-drilled holes in the upper and lower floor slabs, respectively. Finally, concrete is poured between the support members and the hole walls to complete the installation. By using support members and support plates, the flue gas duct can be placed vertically between two adjacent floor slabs, ensuring the installation quality. Simultaneously, the presence of the support plate allows the self-weight load of the flue gas duct to be transferred to the corresponding floor slab, thereby unloading the flue gas duct and preventing its self-weight load from being transferred to the lower floor flue gas duct. Furthermore, since the support components are installed inside the pre-drilled holes and the lower end of the support components can abut against the bottom surface of the floor slab, after the flue is placed, only concrete needs to be poured between the support components and the wall of the pre-drilled holes. There is no need for formwork, the construction steps are simple, and the construction cycle can be effectively shortened. Attached Figure Description

[0037] like Figure 1 and Figure 2 As shown, this embodiment provides a smoke duct installation structure for installing a smoke duct 200 between two adjacent floor slabs 100. The smoke duct installation structure includes a support member 1 and a support plate 2.

[0038] The floor slab 100 is provided with a reserved hole 101. One end of the support member 1 passes through the reserved hole 101, and the other end can abut against the bottom surface of the floor slab 100. The top end of the flue duct 200 below the floor slab 100 can abut against the support member 1. The support plate 2 is provided on the top surface of the floor slab 100 and is connected to the support member 1. The bottom end of the flue duct 200 above the floor slab 100 can abut against the support plate 2.

[0039] The flue gas duct installation structure provided in this embodiment involves first installing support members 1 and support plates 2 at the reserved holes 101 in two adjacent floor slabs 100 during installation of the flue gas duct 200. Then, the flue gas duct 200 is placed between the two adjacent floor slabs 100, with the top end of the flue gas duct 200 abutting against the support member 1 at the reserved hole 101 in the upper floor slab 100, and the bottom end of the flue gas duct 200 abutting against the support plate 2 at the reserved hole 101 in the lower floor slab 100. Both ends of the flue gas duct 200 are connected to the reserved holes 101 in the upper and lower floor slabs 100, respectively. Finally, concrete is poured between the support member 1 and the hole wall of the reserved hole 101 to complete the installation of the flue gas duct 200. By setting the support member 1 and support plate 2, the flue gas duct 200 can be placed vertically between two adjacent floor slabs 100, ensuring the installation quality of the flue gas duct 200. Meanwhile, the presence of the support plate 2 allows the self-weight load of the flue duct 200 to be transferred to the corresponding floor slab 100 through the support plate 2, thereby unloading the flue duct 200 and preventing the self-weight load of the flue duct 200 from being transferred to the flue duct 200 on the lower floor. In addition, since the support member 1 passes through the reserved hole 101 and the lower end of the support member 1 can abut against the bottom surface of the floor slab 100, after the flue duct 200 is placed, it is only necessary to pour concrete between the support member 1 and the hole wall of the reserved hole 101. There is no need for formwork, the construction steps are simple, and the construction period can be effectively shortened.

[0040] Optionally, see Figure 1 , Figure 2 and Figure 3The support member 1 includes a connected cylindrical body 11 and a limiting plate 12. The cylindrical body 11 is inserted into a pre-drilled hole 101, and the limiting plate 12 can fit against the bottom surface of the floor slab 100. The top end of the flue duct 200 abuts against the limiting plate 12. One end of the support plate 2 rests on the floor slab 100, and the other end rests on the cylindrical body 11 and is connected to the limiting plate 12. In this embodiment, the limiting plate 12 is vertically connected to the lower end of the cylindrical body 11. When installing the support member 1, the cylindrical body 11 is inserted into the pre-drilled hole 101 from the lower end of the floor slab 100, and the limiting plate 12 is fitted against the bottom surface of the floor slab 100. Then, the support plate 2 is placed on the top surface of the floor slab 100, and one end of the support plate 2, suspended above the reserved hole 101, is placed on the upper end of the cylinder 11. Finally, the support plate 2 is connected and fixed to the limiting plate 12. The support plate 2 and the limiting plate 12 work together to clamp the floor slab 100, thus fixing the support member 1 to the floor slab 100. Since the limiting plate 12 abuts against the bottom surface of the floor slab 100, and the top of the flue duct 200 abuts against the limiting plate 12, the connection between the flue duct 200 and the reserved hole 101 can be sealed tightly by the limiting plate 12, ensuring a sealed connection after the flue duct 200 is installed. This avoids leakage problems later and improves the construction quality.

[0041] In this embodiment, see Figure 1 The cross-section of the reserved hole 101 is square, so the cylinder 11 is also set as a square cylinder, and the cross-sectional dimension of the cylinder 11 is smaller than the cross-sectional dimension of the flue duct 200. The top of the flue duct 200 abuts against the side of the limiting plate 12 facing away from the floor slab 100 to ensure the verticality of the flue duct 200 installation and avoid the misalignment of the flue duct 200, so as to seal and connect the entire flue duct structure.

[0042] In other embodiments, if the reserved hole 101 is circular, the cylinder 11 can be adapted to be a circular cylinder.

[0043] Optionally, see Figure 1 and Figure 2 The flue gas duct installation structure also includes a connector 3, and a gap 4 is left between the cylinder 11 and the wall of the reserved hole 101 (e.g., Figure 3 As shown, the connector 3 passes through the support plate 2 and extends into the gap 4 to connect with the limiting plate 12. In this embodiment, a nut seat 121 is provided on the limiting plate 12 within the gap 4. The connector 3 includes a fixing rod 31 with external threads, which are threaded to the nut seat 121. When installing the support plate 2, one end of the fixing rod 31 is first inserted into the gap 4 and threaded to the nut seat 121. Then, the other end of the fixing rod 31 passes through the support plate 2, thereby clamping the floor slab 100 together with the limiting plate 12.

[0044] Further, see Figure 3The connecting component 3 also includes a locking component 32 disposed on the fixing rod 31. The locking component 32 is located on the side of the support plate 2 facing away from the limiting plate 12, and the locking component 32 can press the support plate 2 onto the floor slab 100. Preferably, the locking component 32 is a locking nut. The support plate 2 has a through hole, and the end of the fixing rod 31 that passes through the through hole is also provided with an external thread. After the fixing rod 31 is tightened with the nut seat 121, the through hole on the support plate 2 is aligned with the fixing rod 31 so that the fixing rod 31 passes through the through hole, and then the locking nut is screwed on. After tightening the locking nut, the support plate 2 can be securely fixed.

[0045] Optionally, multiple support plates 2 are provided, and the multiple support plates 2 are distributed circumferentially along the reserved hole 101. Each support plate 2 is connected to the limiting plate 12 through a connector 3. In this embodiment, see... Figure 1 There are four support plates 2. One support plate 2 is placed in the middle of each side of the reserved hole 101. On the one hand, it improves the installation stability of the support 1. On the other hand, the four support plates 2 can evenly transfer the self-weight load of the flue duct 200 to the floor slab 100, and prevent the load of the flue duct 200 from being transferred downward.

[0046] In other embodiments, if one side of the flue duct 200 is against a wall, that is, the side of the reserved hole 101 is against a wall, then only three support plates 2 can be set, which can also play a role in unloading.

[0047] Optionally, see Figure 1 The flue gas duct installation structure also includes a concrete filling layer 5, which fills the space between the outer wall of the cylinder 11 and the wall of the reserved hole 101. That is, the gap 4 between the cylinder 11 and the wall of the reserved hole 101 is used for pouring the concrete filling layer 5. The cylinder 11, the limiting plate 12, and the wall of the reserved hole 101 form a pouring cavity. Therefore, no formwork is required when pouring the concrete filling layer 5 in the later stage, which saves the formwork hoisting process and makes the construction steps of the flue gas duct 200 simpler.

[0048] Optionally, the outer wall of the cylinder 11 and the side of the limiting plate 12 facing the floor slab 100 are both provided with concave and convex structures to form a rough surface. That is, the outer wall of the cylinder 11 and the side of the limiting plate 12 facing the floor slab 100 are both roughened, which can increase the contact area between the concrete and the two when the concrete filling layer 5 is poured, prevent the concrete from falling off, and ensure the pouring quality.

[0049] Optionally, both the support member 1 and the support plate 2 are made of stainless steel. Stainless steel is corrosion-resistant, ensuring the installation quality of the flue duct 200 and extending its service life. Furthermore, the fixing rod 31, the nut seat 121, and the locking member 32 are also made of stainless steel to prevent rusting later.

[0050] This embodiment also provides a method for constructing a flue gas duct, which uses the flue gas duct installation structure described above and includes the following steps:

[0051] S1. Install support members 1 in the reserved holes 101 of two adjacent floor slabs 100, and connect and fix the support plate 2 on the corresponding floor slab 100 to the support member 1.

[0052] S2. Install smoke and air ducts 200 between two adjacent floor slabs 100, so that the bottom end of the smoke and air duct 200 abuts against the support plate 2 at the reserved hole 101 of the lower floor slab 100, and the top end of the smoke and air duct 200 abuts against the support member 1 at the reserved hole 101 of the upper floor slab 100, until the smoke and air ducts 200 of all floors are installed.

[0053] The following steps are included after step S2:

[0054] After the installation of S3 and flue duct 200 is completed, concrete is poured between the support member 1 and the hole wall of the reserved hole 101 to form a concrete filling layer 5, and the support member 1 and the support plate 2 are firmly fixed to the floor slab 100.

[0055] In step S1, when installing the support member 1, the cylinder 11 of the support member 1 is inserted from the bottom of the floor slab 100 into the pre-drilled hole 101, so that the limiting plate 12 is in contact with the bottom surface of the floor. Then, one end of the fixing rod 31 is inserted into the gap 4 and screwed onto the nut seat 121. Then, the through hole on the support plate 2 is aligned with the other end of the fixing rod 31, so that the fixing rod 31 passes through the through hole. Finally, the locking nut is screwed onto the fixing rod 31 to lock and fix the support plate 2 and the support member 1, thus completing the installation.

[0056] In step S2, when installing the flue duct 200, the position of the flue duct 200 is adjusted so that the bottom end of the flue duct 200 abuts against the support plate 2 on the lower floor slab 100, and the top end of the flue duct 200 abuts against the limiting plate 12 of the support member 1 of the upper floor slab 100, thus ensuring the verticality of the flue duct 200 installation.

[0057] In step S3, after the flue duct 200 is placed, concrete is poured into the gap 4 between the cylinder 11 and the wall of the reserved hole 101. After the concrete is formed, a concrete filling layer 5 is formed, and the fixing rod 31 and the nut seat 121 are embedded in the concrete filling layer 5. The limiting plate 12 exposed below the floor slab 100 can be hidden by the subsequent ceiling construction. The fixing rod 31 and locking piece 32 exposed above the floor slab 100 can be cut and removed, or hidden during the floor construction.

[0058] The flue gas duct construction method provided in this embodiment, by setting up a support member 1 and a support plate 2, allows the flue gas duct 200 to be vertically placed between two adjacent floor slabs 100, ensuring the installation quality of the flue gas duct 200. Simultaneously, the presence of the support plate 2 allows the self-weight load of the flue gas duct 200 to be transferred to the corresponding floor slab 100 through the support plate 2, thereby achieving unloading of the flue gas duct 200 and preventing the self-weight load of the flue gas duct 200 from being transferred to the lower floor flue gas duct 200. Since the cylinder 11 of the support member 1 passes through the reserved hole 101, and the limiting plate 12 can abut against the bottom surface of the floor slab 100, after the flue gas duct 200 is placed, only concrete needs to be poured between the cylinder 11 and the hole wall of the reserved hole 101, without the need for formwork. The construction steps are simple and can effectively shorten the construction period.
