Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of flues, and particularly relates to a spliced flue. Background Art
[0002] A flue is a pipeline product used to exhaust kitchen fumes or bathroom waste gas, etc., also known as an exhaust flue, a ventilation flue or a residential exhaust flue. At present, the flue in the construction industry has become an independent component, which is produced separately and installed in a unified smoke exhaust area.
[0003] In the existing solutions, in order to improve the smoke-blocking performance of the flue, it is basically formed at one time according to the floor height to reduce the number of interfaces and thus avoid smoke leakage. For example Figure 1 As Figure 2 shown, the square pipe-shaped flue and the L-shaped flue are the two most commonly used solutions in the current market. However, the existing floor height is more than 2.8 meters, making a single flue module large and heavy. Whether in the production, transportation or installation process, at least 4 skilled operators are required, with high operation difficulty, high threshold and high labor cost. Moreover, the safety risks caused by non-standard operation or improper cooperation of personnel cannot be avoided.
[0004] Although there are also small-sized flue module products currently, which solve some installation problems, the actual effect is not good in practice. It is impossible to avoid losing the load-bearing performance of the flue, and even it cannot be effectively sealed.
[0005] In addition, the manufacturing method of the flue module generally uses traditional processes such as lying formwork and plastering, combined with materials such as cement mortar for production. The production efficiency is low, the wall thickness of the product is difficult to meet the standard, the load-bearing capacity is poor, and the loss of the flue module is serious during transportation and installation, increasing the production and installation costs.

[0069] Embodiment 1
[0070] The present utility model provides a spliced flue 100, as Figures 3 - 4 shown, including a flue module 1 plugged together and a seal 2 provided between adjacent flue modules 1. Please, on the basis of Figures 3 - 4 , refer to Figures 5 - 7 , the flue module 1 includes a main body 13 and a first splicing portion 11 and a second splicing portion 12 provided at both ends of the main body 13. A cavity 131 is formed around the inside of the main body 13. The first splicing portion 11 includes a receiving boss 111 and a splicing plug 112. The receiving boss 111 is formed by bending the main body 13 toward the cavity 131. The splicing plug 112 is integrally connected to the receiving boss 111 and extends in a direction away from the second splicing portion 12. The receiving boss 111 is provided with a receiving surface 1111 located outside the splicing plug 112. The second splicing portion 12 is provided with a plugging position 121 and a connecting surface 122. The connecting surface 122 is located on the end surface of the second splicing portion 12. Among them, the splicing plug 112 is inserted into the plugging position 121, the connecting surface 122 abuts against the receiving surface 1111, and the seal 2 fills the space between the splicing plug 112 and the plugging position 121.
[0071] In this embodiment, the plugging position 121 is coplanar with the side of the main body 13 facing the cavity 131, and the second splicing portion 12 is coplanar with the side of the main body 13 away from the inner cavity. In this way, the second splicing portion 12 and the main body 13 can be integrally formed without adding forming structures, making the overall flue module 1 simpler, with good overall strength and more convenient production.
[0072] The first splicing part 11 of the flue module 1 is placed upward. First, the sealant 2 is applied on the first splicing part 11 of the lower flue module 1, and then the second splicing part 12 of the upper flue module 1 is sleeved on the first splicing part 11 of the lower layer. After the sealant 2 solidifies, the connection between the two flue modules 1 is sealed. By providing the first splicing part 11 and the second splicing part 12 on the flue module 1 and arranging the sealant 2 between the adjacent first splicing part 11 and the second splicing part 12, the installer can complete the installation of the flue with only simple installation training and safety learning. The installation operation is simple, convenient and efficient.
[0073] As Figure 8 shown, on two adjacent flue modules 1 spliced together, the insertion position 121, the receiving boss 111 and the splicing plug 112 surround to form a filling cavity 113, and the sealant 2 is filled in the filling cavity 113.
[0074] In some embodiments, in order to facilitate demoulding and improve the connection strength of the receiving boss 111, a demoulding angle 114 is inclinedly provided on the side of the receiving boss 111 facing the main body 13. In addition, after adding the demoulding angle 114, the receiving boss 111 can bear a greater receiving load, improving the strength of the first splicing part 11 of the flue module 1.
[0075] As Figure 9 shown, at the connection of the floor slab 4 between floors of the flue module 1, a reinforcing bar 141 inserted between the first splicing part 11 and the second splicing part 12 is provided. Specifically, it abuts against the connection surface 122 and the receiving surface 1111. The reinforcing bar 141 is arranged in the floor slab 4. After installation, each floor slab 4 bears the weight of the flue on each floor, ensuring that the stress of the flue is dispersed on each floor. While not affecting the installation efficiency and sealing effect, the load-bearing is more reasonable.
[0076] In some embodiments, the splicing plug 112 and the insertion position 121 are provided with convex stripes 1121 and / or grooves 1122 on the surface in contact with the sealant 2. As Figure 10 shown, adding the convex stripes 1121 and / or grooves 1122 increases the adhesion area of the sealant 2 to the first splicing part 11 and the second splicing part 12, making the sealing effect of the sealant 2 better.
[0077] In some embodiments, the main body 13 is of a square or circular structure, the cavity 131 and the splicing plug 112 are also of a square or circular structure, and the splicing plug 112 and the insertion position 121 have the same shape. In different implementation schemes, the shape structures of the main body 13, the cavity 131 and the splicing plug 112 can be the same or different. For example, a square main body 13, a circular cavity 131 and a circular splicing plug 112 are adopted. In this embodiment, in order to meet the current common shape requirements, the main body 13, the cavity 131 and the splicing plug 112 are all square.
[0078] Furthermore, in order to improve the performance of the flue module 1, a steel bar mesh 14 woven by steel bars 141 is arranged inside the flue module 1. And the steel bar mesh 14 is sequentially passed through the first splicing part 11, the main body 13 and the second splicing part 12.
[0079] Please refer to Figures 4 - 10 on the basis of Figure 11 , the steel bar mesh 14 in the shape of a cross is formed by mutually perpendicular fixing of multiple steel bars 141, and one of the fixing directions is perpendicular to the connection surface 122. At the position of the first splicing part 11, the steel bar mesh 14 is inclined and bent towards the cavity 131 and passes through the position of the receiving boss 111 or the inverted die angle 114.
[0080] In this embodiment, the position where the steel bar mesh 14 is inclined and bent passes through the position of the inverted die angle 114. The end of the steel bar mesh 14 is arranged inside the splicing plug 112. The inclined and bent steel bar mesh 14 can ensure that the overall load-bearing capacity of the flue module 1 is greater and the internal load-bearing capacity is better.
[0081] In this embodiment, the steel bar mesh 14 is woven by steel bars 141. In other embodiments, the steel bar mesh 14 can be obtained by mutually interweaving and welding the steel bars 141, or other methods can be used to firmly form the steel bar mesh 14 with the steel bars 141.
[0082] Furthermore, inside the splicing plug 112, there are steel bars 141 horizontally surrounding the splicing plug 112, and inside the connection surface 122, there are steel bars 141 horizontally surrounding the connection surface 122. Inside the splicing plug 112 and the connection surface 122, there are horizontally surrounding steel bars 141, which reduces the deformation of the first splicing part 11 and the second splicing part 12 during handling and transportation, and also reduces the forming deformation error. Ensure that when installed, the flue splicing is accurately formed and beautiful.
[0083] In some embodiments, the periphery of the steel bar mesh 14 is also wrapped with a forming part 15, and the flue module 1 is integrally solidified and formed by the steel bar mesh 14 and the forming part 15. During production, only by integrally solidifying and forming the steel bar mesh 14 and the forming part 15, the above-mentioned high-quality flue module 1 can be produced without adding too many materials and accessories.
[0084] Specifically, the seal 2 is a leak-proof cement sealant or a leak-proof tile adhesive. The formed part 15 is formed by the setting and hardening of concrete with cement as the gelling material, and the interior of the formed part 15 is dense and pore-free. In this embodiment, the seal 2 is selected as a leak-proof cement sealant, and the formed part 15 is concrete formed by using small stones with a specification of 1.0 or less as the aggregate, and then using cement as the gelling material and mixing with fine sand. Compared with the commonly used cement mortar and soft fiber materials at present, using the above-mentioned concrete can better improve the overall strength and hardness of the flue, and the requirement of dense interior texture and pore-free can further improve the stability of the overall structure of the flue.
[0085] In summary, for the above-mentioned spliced flue 100, compared with the existing flues such as Figure 1 and Figure 2 the shown flue, by setting the first splicing part 11 and the second splicing part 12 on the flue module 1, filling the seal 2 between the adjacent first splicing part 11 and the second splicing part 12, and using the steel mesh 14 and the formed part 15 for forming. On the premise that the smoke closing performance and strength are not affected, the size and volume can be made smaller. In this way, in actual use, the flue module 1 can be produced, transported and assembled by only 1-2 people. Compared with the existing operation team of 4-6 people, the number of operators is reduced, and the safety of personnel in the whole process of the flue industry is improved. Moreover, the structure is simple, the installation is convenient, the operation threshold of personnel is low, and the learning cost of operators is effectively reduced. At the same time, because the size and volume are controllable and can be made smaller, in the whole process of the flue industry, personnel can complete it with the help of auxiliary equipment such as transport forklifts and vertical elevators, reducing the physical loss of personnel and the physical requirements of operation. In addition, during transportation, the flue module is not restricted by the road and vehicle size, and the transportation is safer and the cost is lower.
[0086] Secondly, by setting the first splicing part 11 and the second splicing part 12 on the flue module 1 and filling the seal 2 between the adjacent first splicing part 11 and the second splicing part 12, compared with the existing method of using external plastering or applying the sealant 203 on the outside for sealing and leak prevention in flue installation, the flue module 1 in this embodiment is not affected by the installation position of the flue. Even in the blocked positions such as the corner and the wall side, the joints of the flue module 1 can be effectively sealed. By adding the convex stripes 1121 and / or the grooves 1122, the adhesion area of the seal 2 to the first splicing part 11 and the second splicing part 12 is increased, and the leak-proof performance is better.
[0087] Thirdly, the steel mesh 14 and the formed part 15 are integrally solidified and formed, and the formed part 15 has a dense texture and no pores. Compared with the existing production by using wire meshes, fiber products and cement mortar, the performance of the flue is better than that of the existing flue in terms of strength and durability. Especially during transportation and installation, the flue module 1 is not easy to crack and break under daily bumps.
[0088] It should be noted that in the current urban renewal projects, if the existing flue modules are used for installation, due to the insufficient space of the stair dimensions in old buildings, it is basically impossible to transport the flue modules to the designated installation positions by manpower. And using equipment for hoisting will undoubtedly increase the safety risk of handling. If split flues are used, the sealing performance of the flues will be greatly reduced, which is not conducive to the development and popularization of flues. In the spliced flue 100 described in this embodiment, the weight of a single flue module 1 can be controlled within 80 kg, and the length dimension can be controlled within 1.5 m. When loading, unloading or handling, it is placed on a pallet, and with the use of a manual forklift and a vertical lift in the construction site, a single person can complete the handling work. If manual handling is required, the weight can be further reduced, and the upward handling work can still be completed by tools such as a backpack or a planetary wheel handcart, so that the handling work can be completed by a single person.
[0089] Embodiment 2
[0090] This embodiment provides a manufacturing method for manufacturing the flue module 1 described in Embodiment 1. Among them, the interior of the flue module 1 is a steel mesh 14 woven by steel bars 141, and a forming member 15 is wrapped around the periphery of the steel mesh 14. The flue module 1 is integrally solidified and formed by the steel mesh 14 and the forming member 15.
[0091] During the manufacturing process, a production assembly 3 including an outer mold 31, an inner mold 32, a vibrator platform 34, etc. is used, and a mold release agent is used in cooperation. A mold cavity 311 is provided inside the outer mold 31. The inner mold 32 is detachably arranged inside the mold cavity 311 and surrounds a flue forming cavity 33 with the outer mold 31. The outer mold 31 and the inner mold 32 are placed on the vibrator platform 34. After the vibrator platform 34 is started, it can generate low-frequency vibrations. In addition, the production assembly 3 further includes a scraper 35.
[0092] Please refer to Figures 12 - 16 , and the specific manufacturing method is as follows:
[0093] S1: Uniformly apply a mold release agent on the inner surface of the outer mold 31 and the outer surface of the inner mold 32. Use a brush or other tools that can evenly apply the mold release agent, so that the shaped flue module 1 can be easily separated from the outer mold 31 and the inner mold 32, and there is no adhesion on the surface of the flue module 1, which is convenient for mold removal and improves efficiency.
[0094] S2: Sleeves the outer mold 31, the already formed steel mesh 14, and the inner mold 32 from the outside to the inside above the vibrator platform 34 in sequence, and places one end of the flue forming cavity 33 for forming the first splicing part 11 on the vibrator platform 34. The steel mesh 14 is arranged inside the flue forming cavity 33. Since the shape of the steel mesh 14 can be easily distinguished from those of the outer mold 31 and the inner mold 32, it is not easy to have a direction error, and the steel mesh 14 can be prefabricated in advance, improving the standardization degree of production and the overall production efficiency.
[0095] S3: Starts the vibrator platform 34, and pours the fluid-shaped forming piece 15 at one end of the flue forming cavity 33 far from the vibrator platform 34 until the flue forming cavity 33 is filled. The vibrator platform 34 can effectively discharge the gas inside the forming piece 15, ensuring that the inside of the forming piece 15 is dense and pore-free, improving the strength and hardness after solidification.
[0096] S4: When it is observed that on the side of the flue forming cavity 33 far from the vibrator platform 34, there is no dynamic porridge-like change in the forming piece 15, turns off the vibrator platform 34, and makes the forming piece 15 flush with the edge of the flue forming cavity 33. When there is no dynamic porridge-like change, it indicates that there is no air left inside the forming piece 15. After turning off the vibrator platform 34, uses the scraper 35 to scrape off the part of the forming piece 15 exposed outside the flue forming cavity 33, ensuring that the forming piece 15 is flat and up to standard at the second splicing part 12, facilitating subsequent installation.
[0097] S5: After waiting for the forming piece 15 to solidify, first takes out the inner mold 32, and then turns the outer mold 31 with the flue module 1 by 180° in the vertical direction to take out the outer mold 31.
[0098] S6: Places the flue module 1 produced in step S5 outdoors for natural curing treatment. The outer mold 31 and the inner mold 32 repeat the above process to cycle and produce the next flue module 1.
[0099] Using the production method provided above, through a set of inner and outer molds and equipped with a general cement vibrator and mold release agent, only one person can efficiently and batch-produce the flue module 1. The flue module 1 can easily meet the flue thickness of the national standard. And through the vibration of the vibrator platform 34, the material inside the forming piece 15 is more compact and pore-free, improving the overall strength and hardness of the flue module 1, effectively avoiding the situation of cracking during the transportation and installation process of the flue, resulting in smoke leakage and air leakage, and thus ensuring the final quality of the flue after splicing and installation. Under the guarantee of the production process, the flue module 1 with the above structure, after testing, when dropped from a height of 1 meter, the overall structure and splicing position of the flue module 1 are intact, and the smoke-blocking effect and strength requirements can still be ensured after installation.
[0100] Embodiment 3
[0101] As Figure 17 shown, in this embodiment, the flue module 1 in Embodiment 1 is used for splicing. However, different from Embodiment 1, at a position close to the top of the floor, a tail flue module 5 is provided. The length direction of the splicing plug 112 of the tail flue module 5 passes through the top of the floor and protrudes from the bottom of the upper floor slab 4. To meet the fixing requirements, the splicing plug 112 of the tail flue module 5 is fixed in the upper floor slab 4. The splicing plug 112 protruding from the bottom of the upper floor slab 4 can be used as the splicing starting point of the upper-layer spliced flue 100, and the plugging and sealing method between the flue modules 1 is the same as that in Embodiment 1.
[0102] The tail flue module 5 adopted in this embodiment can make the flue splicing between floors continuous. During the process of installing and fixing the flue, each floor can pre-install the tail flue module 5 to ensure that the flue construction on each floor is not restricted by the personnel batch and time. At the same time, the first flue module 1 below each floor does not need to be buried in the floor slab 4, which can improve the sealing performance of the flue in the floor slab 4.
[0103] Embodiment 4
[0104] As Figures 18 - 19 shown, this embodiment provides a second flue module 6. Its structure is the same as that of the flue module 1 in Embodiment 1. However, different from Embodiment 1, the main body 13 of the second flue module 6 adopts a square structure, while the cavity 131, the splicing plug 112 and the plugging position 121 adopt a circular structure. During splicing, the splicing plug 112 and the plugging position 121 with circular structures do not need to consider implementation steps such as alignment shape, and can be quickly spliced, and then rotated and aligned according to the shape. The work that originally required one person to carry and another person to align now only requires one person to place and adjust. Further reduce the construction difficulty of splicing the flue module 1. And the cavity 131 adopts a circular structure, which cooperates with the square main body 13, making the load-bearing of the flue better, and the area of the bearing surface 1111 and the connecting surface 122 larger and more stable, which is suitable for flue construction with a larger floor height.
[0105] In addition, the steel mesh 14 inside the second flue module 6 can be increased by one layer in the direction of the cavity 131 according to actual needs to improve the structural stability of the cavity 131 position.
[0106] The above content is only an example and description of the structure of the present utility model. Its description is relatively specific and detailed, but it cannot be understood as a limitation of the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these obvious replacement forms all belong to the protection scope of the present utility model.
