Abstract
Description
Technical Field
[0001] This invention belongs to the field of building construction technology, and more specifically, relates to an integrated flue installation device and construction method. Background Technology
[0002] In the field of building construction technology, flues are the core facilities for smoke exhaust and ventilation in spaces such as kitchens and bathrooms. Their design and installation quality directly affects the safety, functionality, and service life of a building. During flue installation, different installation methods have varying impacts on the flue's sealing and reliability.
[0003] Traditional flue installation techniques often involve prefabricating components in sections and then assembling them on-site. This requires reserving openings during structural construction. Before installing the flue, drilling and rebar installation are used, typically employing two 12mm-14mm threaded steel bars for support and load reduction. A water-retaining sill is usually required between the flue and the floor slab structure, which is constructed using a secondary pour. Cement mortar is then used to fill the gaps between the flue and the floor slab. This process makes the flue and the structure prone to collisions and damage during installation, and the water-retaining sill structure is prone to leakage due to cracks. Furthermore, the difficulty in setting up the formwork for the cement mortar filling gaps results in poor filling quality. For example, patent document CN113526328A discloses a flue installation device, including a support frame, a pulley block rotatably mounted on the support frame, a handle driven by the pulley block, and a lifting rope for connecting the flue pipe. The lifting rope is connected to and wound around the pulley block to move the flue installation device to each floor for lifting and fixing the flue pipes on each floor, thereby connecting the flue pipes on each floor to form a flue.
[0004] However, patent document CN113526328A still has the following problems: This flue installation device is used for on-site splicing of flue installation and does not involve the problems of smoke leakage and water leakage at the flue. Using this device can efficiently complete the installation of the flue, but it cannot effectively solve the pain points of the existing flue. As the flue is used for a long time, the gaps at the flue have an increasingly greater impact on smoke leakage and water leakage, and the problem is significant. Summary of the Invention
[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides an integrated flue installation method. By setting a water-blocking curb at the flue opening, water stains from the bathroom and kitchen floors are prevented from seeping into the gaps between the flue and the interior walls, thus preventing water leakage. The flue is fixed by an L-shaped aluminum alloy bracket, solving the problem of difficult formwork erection between the flue and the floor slab. The bracket can be reused after removal, reducing material and labor costs. By filling the gaps with cement mortar, polymer waterproof mortar, sealant, cement-based penetrating crystalline waterproof coating, and JS waterproof coating, smoke and water leakage at the flue can be effectively prevented.

[0017] Furthermore, the cement-based penetrating crystalline waterproof coating is applied between the flue and the interior wall.
[0018] Furthermore, the flue sealing and waterproofing construction structure also includes a graphite plate corner guard strip located on the inner side of the flue.
[0019] According to a second aspect of the present invention, a method for installing an integrated flue is provided, which is implemented using an integrated flue installation device, comprising:
[0020] S100: Select appropriate flue materials according to design requirements. It is necessary to check the specifications, dimensions, and appearance quality of the flue in detail to ensure that there are no cracks, damages, or other problems. The following auxiliary materials also need to be prepared: polymer waterproof mortar, cement-based penetrating crystallizing waterproof coating, L-shaped aluminum alloy bracket, bottom sealing template, pins, foaming agent, cement mortar, etc.
[0021] S200: The structural floor slab and the area around the flue opening need to be cleaned and roughened. Check whether the position and size of the reserved holes meet the requirements and ensure that the installation controls meet the construction needs.
[0022] S300: Reinforcement binding of structural floor slab, reservation of flue opening, embedded support components are pre-installed along with reinforcement binding of structural floor slab, water-retaining curb is set around flue opening, water-retaining curb is poured at the same time as structural floor slab, and three-section embedded bolts are reserved at the bottom of water-retaining curb.

[0024] S500: Remove the L-shaped aluminum alloy bracket and bottom closed formwork, then fill the gaps at the flue joint with cement mortar. Use polymer waterproof mortar as a bottom sealant between the flue and the structural floor slab. Fill the gap between the water-retaining curb and the flue with cement mortar, ensuring it is compacted.

The protective layer is made of fine stone concrete with double-layer steel wire mesh inside. Apply 5mm crack-resistant mortar and hang alkali-resistant mesh cloth on the surface of the protective layer. Apply a layer of JS waterproof coating to the floor slab structure, interior walls, ceiling, top surface of the water-retaining sill and 300mm above the flue.

[0025] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:
[0026] 1. The installation device of the present invention, by setting a water-blocking curb at the flue opening, prevents water stains from the bathroom and kitchen floors from seeping into the gaps between the flue and the interior walls, thus preventing water leakage. The flue is fixed by an L-shaped aluminum alloy bracket, which solves the problem of difficult formwork erection between the flue and the floor slab.

[0027] 2. The installation device of the present invention pre-cleans the structural floor slab and roughens the area around the flue opening to ensure that the installation space meets the construction requirements. The water-retaining curb is poured at the same time as the structural floor slab. The water-retaining curb needs to be designed with a 1%-2% inclination to prevent water stains from the bathroom and kitchen floor from seeping into the flue and the gaps in the interior and exterior walls, thus forming an effective water barrier to prevent water leakage.
[0028] 3. The installation device of the present invention has an aluminum alloy crossbar at the top of the L-shaped aluminum alloy bracket and a template support in the middle. The L-shaped aluminum alloy brackets are connected by pins. After the flue is adjusted to meet the installation requirements, the L-shaped aluminum alloy brackets are used to fix the flue to the structural floor slab and the interior wall. After the subsequent waterproofing construction and caulking are completed, all L-shaped aluminum alloy brackets are removed. This construction method solves the problem of difficult template erection between the flue and the structural floor slab. The L-shaped aluminum alloy brackets can be reused after removal, reducing the expenditure of materials and labor costs.
[0029] 4. In the installation device of this invention, the flue interface is sealed with cement mortar, the gap between the flue and the structural floor slab is sealed with polymer waterproof cement grout, and the gap between the water-retaining curb and the flue is filled tightly with cement mortar. A 15mm deep groove is reserved between the top of the water-retaining curb and the flue, and a waterproof sealant is applied to the groove. A layer of cement-based penetrating crystalline waterproof coating is applied between the flue and the interior wall, with a height of 300mm above the finished surface. Micro-expansion fine stone concrete is poured, and finally, a foaming agent is used to seal the gap. A layer of cement-based penetrating crystalline waterproof coating is applied to the top surface of the structural floor slab, the water-retaining curb, and 300mm above the flue. A layer of JS waterproof coating is applied to the top surface of the water-retaining curb and 300mm above the flue.

Detailed Implementation
[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.
[0039] This invention provides a method for installing an integrated flue. For example... Figure 2 , 3As shown in Figures 4, 5, 6, and 7, the structure includes the pre-reserved opening for the flue, the flue installation and bottom sealing structure, and the flue sealing and waterproofing construction structure. The pre-reserved opening for the flue includes a structural floor slab 1, a water-retaining curb 2, embedded support components 3, a water-stop steel sheet 4, three-section embedded bolts 5, the flue 6, and an interior wall 7. The three-section embedded bolts 5, pre-reserved at the bottom of the water-retaining curb 2, are used to seal the bottom of the flue 6, thus fixing the formwork. The flue installation and bottom sealing structure includes an L-shaped aluminum alloy bracket 8, a bottom sealing template 9, a polymer anti-cement grout bottom plug 10, an aluminum alloy crossbar 12, and a pin 13. The flue 6 is vertically placed into the reserved hole. The verticality and horizontality of the flue are checked with a spirit level and a plumb bob. The flue 6 is fixed to the indoor wall 7 with the L-shaped aluminum alloy bracket 8. The aluminum alloy crossbar 12 is installed on the L-shaped aluminum alloy bracket 8. A template support is provided in the middle. The L-shaped aluminum alloy brackets 8 are connected by pins 13. The bottom sealing template 9 is installed on the top of the L-shaped aluminum alloy bracket 8. The bottom sealing template 9 is fixed with three-section pre-embedded bolts 5. The flue sealing and waterproofing construction includes foaming agent 11, cement-based penetrating crystalline waterproof coating 14, extruded polystyrene board 15, fine aggregate concrete 16, underfloor heating pipe 17, crack-resistant mortar with alkali-resistant mesh 18, JS waterproof coating 19, glazed tiles 20, autoclaved aerated concrete wall 21, micro-expansion fine aggregate concrete 22, sealant 23, cement mortar 24, cement mortar sealing 25, and graphite board corner protectors 26. Cement mortar sealing 25 is applied at the interface of flue 6, and polymer waterproof mortar bottom plug 10 is used between flue 6 and structural floor slab 1. The space between the water-retaining curb 2 and the flue 6 is filled tightly with cement mortar 24. A 15mm deep groove is reserved between the top of the water-retaining curb 2 and the flue 6. Waterproof sealant 23 is applied to the groove. A layer of cement-based penetrating crystalline waterproof coating 14 is first applied between the flue 6 and the interior wall 7, with a height of 300mm above the finished surface. Micro-expansion fine stone concrete 22 is poured, and finally foaming agent 11 is used to seal the joint. This waterproof structure provides seamless waterproof connection and sealing from both the top and bottom ends of the flue. The waterproof structure is reasonable and can effectively prevent smoke from seeping and water from leaking at the flue. The installation device of this invention prevents water stains from the bathroom and kitchen floors from seeping into the gaps between the flue and the interior walls by setting a water-blocking curb at the flue opening, thus preventing water leakage. The flue is fixed by an L-shaped aluminum alloy bracket, which solves the problem of difficult formwork erection between the flue and the floor slab. The bracket can be reused after removal, reducing material and labor costs. By filling the gaps with cement mortar, polymer waterproof mortar, sealant, cement-based penetrating crystalline waterproof coating, and JS waterproof coating, the device can effectively prevent smoke from seeping through and water from leaking into the flue.
[0040] like Figure 2As shown, in the construction of the reserved opening in the flue, the embedded support 3 is tied with the floor slab reinforcement to avoid the cost of installing the embedded support 3 after the structural floor slab 1 is poured. The embedded support 3 is set at the opening of the flue 6. The embedded support 3 is in the form of two 14mm diameter grade III threaded steel bars, one end of which is anchored into the structural floor slab 1, and the other end is anchored into the interior wall 7. The anchoring depth must meet the specifications and design requirements to ensure that the support is installed firmly. A water-retaining curb 2 is set around the opening of the flue 6. The water-retaining curb 2 is poured at the same time as the structural floor slab 1. The water-retaining curb 2 can prevent water stains from the bathroom and kitchen floor from seeping into the gap between the flue 6 and the interior wall 7, thus preventing water leakage. A three-section embedded bolt 5 is reserved at the bottom of the water-retaining curb 2, and a water-stop steel plate 4 is in the middle of the three-section embedded bolt 5. The installation device of the present invention pre-cleans the structural floor slab and roughens the area around the flue opening to ensure that the installation space meets the construction requirements. The water-retaining curb is poured at the same time as the structural floor slab. The water-retaining curb needs to be designed with a 1%-2% inclination to prevent water stains from the bathroom and kitchen floor from seeping into the flue and the gaps in the interior and exterior walls, thus forming an effective water barrier to prevent water leakage.
[0041] like Figure 3 , 4 As shown in Figure 7, during the installation and bottom sealing of the flue, it is necessary to first use an ink line to mark the center line and edge line of the flue 6 to determine its accurate position. Graphite corner protectors 26 are then adhesively bonded to the inner corners of the flue 6. These corner protectors 26 provide protection for the flue 6 throughout the installation process and also serve a fireproof function. The flue 6 is then vertically inserted into the pre-drilled hole, and the verticality and horizontality of the flue 6 are checked using a spirit level and plumb bob, adjusting the flue 6 to meet the requirements. Then, the flue 6 is firmly fixed to the structural floor slab 1 and the interior wall 7 using L-shaped aluminum alloy brackets 8. The aluminum alloy crossbars 12 in the L-shaped aluminum alloy brackets 8 have template support components in the middle. The L-shaped aluminum alloy brackets 8 are connected by pins 13. The bottom closed template 9 is installed on the top of the L-shaped aluminum alloy brackets 8 and fixed with three-section pre-embedded bolts 5. This structure solves the problem of difficult template erection between the flue and the structural floor slab. The bracket can be reused after removal, reducing material and labor costs. The installation device of this invention features an L-shaped aluminum alloy bracket with an aluminum alloy crossbar at the top and a template support in the middle. The L-shaped aluminum alloy brackets are connected by pins. After the flue is adjusted to meet the installation requirements, the L-shaped aluminum alloy brackets are used to firmly fix the flue to the structural floor slab and the interior wall. After completing the subsequent waterproofing and caulking, all the L-shaped aluminum alloy brackets are removed. This structure solves the problem of difficult template erection between the flue and the structural floor slab. The L-shaped aluminum alloy brackets can be reused after removal, reducing material and labor costs.
[0042] like Figure 5 , 6As shown in Figure 7, in the construction of the flue sealing and waterproofing, cement mortar is used to seal the joint of flue 6. Polymer waterproof cement grout is used as a bottom sealant 10 between flue 6 and structural floor slab 1. Cement mortar is used to fill the gap between the water-retaining curb 2 and flue 6 tightly. A 15mm deep groove is reserved between the top of the water-retaining curb 2 and flue 6. Waterproof sealant 23 is applied to the groove. The L-shaped aluminum alloy bracket 8 and the bottom sealing template 9 are removed. A layer of cement-based penetrating crystalline waterproof coating 14 is applied between flue 6 and interior wall 7, with a height of 300mm above the finished surface. Micro-expansion fine stone concrete 22 is poured, and finally foaming agent 11 is used to seal the joint. A layer of cement-based penetrating crystalline waterproof coating 14 is applied to the top surface of structural floor slab 1, water-retaining curb 2 and 300mm above flue 6. Extruded polystyrene board 15 is laid. Underfloor heating pipes 17 are installed and fixed. Underfloor heating protective layer is poured. The protective layer is made of fine stone concrete 16 and reinforced with double-layer steel. The wire mesh is coated with 5mm of crack-resistant mortar and then covered with alkali-resistant mesh cloth 18. A layer of JS waterproof coating 19 is applied to the top of the floor slab structure 1, interior walls 7, ceiling, water-retaining curb 2, and 300mm above the flue 6. An autoclaved aerated concrete wall 21 is built on the top of the water-retaining curb 2 up to the ceiling. This waterproof structure provides seamless waterproof connection and sealing from both ends of the flue. The reasonable waterproof structure can effectively prevent smoke and water leakage at the flue. The construction of glazed tiles 20 on the ground and walls is completed.
[0043] like Figure 1 As shown, the present invention provides an integrated flue installation method, comprising the following steps:
[0044] Select appropriate flue materials according to design requirements. It is necessary to check the flue's specifications, dimensions, and appearance quality in detail to ensure that the flue is free of cracks, damage, and other problems. The following auxiliary materials also need to be prepared: polymer waterproof mortar, cement-based penetrating crystallizing waterproof coating, L-shaped aluminum alloy bracket, bottom sealing template, pins, foaming agent, cement mortar, etc.
[0045] The structural floor slab and the area around the flue opening need to be cleaned and roughened. The location and size of the reserved holes need to be checked to ensure that the installation controls meet the construction needs.
[0046] The structural floor slab reinforcement is tied, the flue opening is reserved, and the embedded support is pre-installed along with the structural floor slab reinforcement. A water-retaining curb is set around the flue opening. The water-retaining curb is poured at the same time as the structural floor slab. Three-section embedded bolts are reserved at the bottom of the water-retaining curb.
[0047] According to the design drawings, use ink lines to mark the center line and edge line of the flue at the installation location. Place the flue into the reserved hole, and use a spirit level and plumb bob to confirm that the verticality and horizontality of the flue meet the requirements. Then, use L-shaped aluminum alloy brackets to firmly fix the flue to the structural floor slab and interior wall.
[0048] Remove the L-shaped aluminum alloy bracket and bottom closed formwork. Then, seal the joints at the flue interface with cement mortar. Use polymer waterproof mortar as a bottom sealant between the flue and the structural floor slab. Fill the gap between the water-retaining curb and the flue with cement mortar, ensuring it is compacted. Leave a 15mm deep groove between the water-retaining curb and the flue. Apply waterproof sealant to the groove, then apply a layer of cement-based penetrating crystalline waterproof coating, 300mm above the finished surface. Pour micro-expansion fine aggregate concrete, and finally seal the joints with foaming agent. Apply the same sealant to the structural floor slab and water-retaining curb. Apply a layer of cement-based penetrating crystalline waterproof coating to the top surface of the sill and 300mm above the flue. Lay extruded polystyrene board, install and fix the underfloor heating pipes, and pour the underfloor heating protective layer. The protective layer is made of fine stone concrete with double-layer steel wire mesh inside. Apply 5mm crack-resistant mortar and hang alkali-resistant mesh on the surface of the protective layer. Apply a layer of JS waterproof coating to the floor slab structure, interior walls, ceiling, top surface of the water-retaining sill and 300mm above the flue. Construct an autoclaved aerated concrete wall from the top of the water-retaining sill to the ceiling. Finally, complete the construction of glazed tiles on the floor and walls.
[0049] In summary, the construction method of this invention involves sealing the flue joint with cement mortar, using polymer-modified waterproof cement grout as a bottom sealant between the flue and the structural floor slab, and tightly filling the gap between the water-retaining curb and the flue with cement mortar. A 15mm deep groove is left between the top of the water-retaining curb and the flue, and waterproof sealant is applied to the groove. A layer of cement-based penetrating crystalline waterproof coating is applied between the flue and the interior wall, extending 300mm above the finished surface. This is then poured with micro-expansion fine aggregate concrete, and finally sealed with a foaming agent. A layer of cement-based penetrating crystalline waterproof coating is applied to the top surface of the structural floor slab, the water-retaining curb, and 300mm above the flue. A layer of JS waterproof coating is applied to the top surface of the water-retaining curb and 300mm above the flue. This waterproof structure provides seamless waterproofing and sealing from both ends of the flue. The reasonable waterproof structure effectively prevents smoke and water leakage at the flue, thus effectively avoiding smoke and water leakage problems that may occur at the flue after construction and waterproofing are completed.

S400: According to the design drawings, use ink lines to mark the center line and edge line of the flue at the installation position, put the flue into the reserved hole, use a spirit level and plumb bob to confirm that the verticality and horizontality of the flue meet the requirements, and then use L-shaped aluminum alloy brackets to firmly fix the flue to the structural floor slab and interior wall. S500: Remove the L-shaped aluminum alloy bracket and bottom closed formwork, then fill the gaps at the flue joint with cement mortar. Use polymer waterproof mortar as a bottom sealant between the flue and the structural floor slab. Fill the gap between the water-retaining curb and the flue with cement mortar, ensuring it is compacted. Leave a 15mm deep groove between the water-retaining curb and the flue, apply waterproof sealant to the groove, and then apply a layer of cement-based penetrating crystalline waterproof coating, 300mm above the finished surface. Pour micro-expansion fine aggregate concrete, and finally seal the joints with foaming agent. On the structural floor slab... Apply a layer of cement-based penetrating crystalline waterproof coating to the top surface of the water-retaining sill and 300mm above the flue. Lay extruded polystyrene board, install and fix the underfloor heating pipes, and pour the underfloor heating protective layer. The protective layer is made of fine stone concrete with double-layer steel wire mesh inside. Apply 5mm crack-resistant mortar and hang alkali-resistant mesh cloth on the surface of the protective layer. Apply a layer of JS waterproof coating to the floor slab structure, interior walls, ceiling, top surface of the water-retaining sill and 300mm above the flue. Construct an autoclaved aerated concrete wall from the top of the water-retaining sill to the ceiling. Finally, complete the construction of glazed tiles on the floor and walls.
