Description

Technical Field

[0001] This utility model relates to the field of construction tools, and in particular to a flue sealing device. Background Technology

[0002] With the booming development of the construction industry, construction safety has received increasing attention. Among these, edge protection of floors and the sealing of horizontal and vertical openings within buildings are key safety hazards in construction. Especially in residential projects, each floor has kitchen exhaust duct openings. If these horizontal openings are not effectively sealed, they will pose a serious threat to the safety of construction workers.

[0003] Currently, most construction sites use old formwork in conjunction with timber to seal flue openings. This traditional sealing method has the following problems: First, because the formwork material is relatively soft, it is easily damaged and difficult to repair once damaged; second, the fixed connection between the formwork and the timber is not strong enough and is prone to loosening; third, when it is necessary to open or reseal the opening, the timber and formwork need to be repeatedly disassembled and reassembled, which is cumbersome and time-consuming; finally, the formwork and timber are easily damaged after multiple uses and cannot be reused, resulting in waste and increased construction costs. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a flue sealing device that is stable, easy to operate and reusable.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A flue sealing device for blocking a flue opening includes: a square flue opening located at a corner of a wall, with two sides flush with the ground and the other two sides close to the wall; a steel platform for sealing the flue opening, the area of ​​the steel platform being larger than the area of ​​the flue opening; and limiting posts disposed on the lower surface of the steel platform, wherein when the steel platform covers the flue opening, the outer surface of the limiting posts corresponds to the two inner walls of the flue opening furthest from the wall; wherein, when the steel platform moves to the flue opening, the limiting posts abut against the two inner walls of the flue opening furthest from the wall, and the friction between the limiting posts and the inner walls of the flue opening keeps the steel platform stable.

[0007] Furthermore, there are three limiting posts, one of which is located on the lower surface of the steel platform away from the corner of the wall, and the other two limiting posts are located on the two adjacent sides of the corner.

[0008] Furthermore, the limiting post is an angle iron, which is welded and fixed to the lower surface of the steel platform.

[0009] Furthermore, the length of the limiting post is greater than the height of the inner wall surface, and the bottom end of the limiting post is provided with a locking part. The locking part is an outwardly bent L-shaped structure. When the steel platform is covered on the flue opening, the locking part and the bottom of the inner wall surface form a locking engagement.

[0010] Furthermore, a temporary window is provided in the middle of the steel platform, and a cover plate is provided at the temporary window. The cover plate is hinged to the steel platform by a hinge, and the cover plate can be rotated by hinge to open or close the temporary window.

[0011] Furthermore, the cover plate includes two split sub-cover plates, which are respectively hinged to the opposite sides of the temporary window via hinges, and each sub-cover plate has a first handle at its free end.

[0012] Furthermore, a second handle is provided on the upper surface of the platform along the outer periphery of the temporary window.

[0013] Furthermore, the steel platform is provided with buffer elements at two edges near the wall. The buffer elements are rubber strips and are fixed to the steel platform by adhesive or bolts.

[0014] Furthermore, the buffer is provided along the two edges of the steel platform near the wall, or at the three corners of the steel platform near the wall.

[0015] Furthermore, a balancer is provided on the steel platform, and the balancer has a base, which is fixed to the upper surface of the steel platform.

[0016] The beneficial effects of this utility model are:

[0017] This utility model discloses a flue sealing device that significantly improves the strength and durability of the sealing device by replacing traditional templates and timber with a steel platform. It can be reused repeatedly without easily being damaged, effectively reducing construction costs. By setting a structure in which a limiting post engages with the inner wall of the flue opening, friction is used to achieve stable support for the steel platform, eliminating the need for additional fixing components. This ensures structural stability and simplifies installation and disassembly. The tight fit between the outer surface of the limiting post and the inner wall of the flue opening also prevents the steel platform from swaying. The overall structure is simple and reasonable, easy to operate, and can be opened and closed at any time according to construction needs, improving construction efficiency while ensuring safety during construction.

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0027] Reference Figure 1A flue sealing device is disclosed for covering a square flue opening located at a corner of a wall. Two sides of the flue opening are flush with the ground, and the other two sides are close to the wall. The device includes a steel platform 1, which is larger than the area of ​​the flue opening, for sealing the flue opening. A limiting post 2 is located on the lower surface of the steel platform 1. When the steel platform 1 covers the flue opening, the outer surface of the limiting post 2 corresponds to the two inner walls of the flue opening furthest from the wall. When the steel platform 1 moves to the flue opening, the limiting post 2 abuts against the two inner walls of the flue opening furthest from the wall, and the friction between the limiting post 2 and the inner walls of the flue opening keeps the steel platform 1 stable. When it is necessary to seal the flue opening at the corner, the steel platform 1 is moved above the flue opening. Because the area of ​​the steel platform 1 is larger than the area of ​​the flue opening, it can completely cover the flue opening. The limiting posts 2, installed on the lower surface of the steel platform 1, insert into the flue opening. Once the steel platform 1 is fully closed, the outer surfaces of the limiting posts 2 will make tight contact with the two inner walls of the flue opening furthest from the wall. At this point, the friction between the limiting posts 2 and the inner walls of the flue opening prevents the steel platform 1 from shifting, thus achieving stable positioning. For example, during residential building construction, when workers need to temporarily seal the kitchen flue opening on a certain floor, they only need to move the steel platform 1 above the flue opening, and the sealing can be quickly completed through the cooperation of the limiting posts 2 and the inner walls, without the need for additional fixing measures. When it needs to be reopened, the steel platform 1 can be easily removed, greatly improving construction efficiency.

[0028] Furthermore, there are three limiting posts 2. One limiting post 2 is located at the corner of the lower surface of the steel platform 1, away from the wall corner, and the other two limiting posts 2 are located on the two adjacent sides of the corner. This arrangement forms a stable three-point support structure. The three-point arrangement of the limiting posts 2 allows for more reliable contact with the inner wall of the flue opening. The combined friction of the three points further improves the stability of the steel platform 1 during use. The limiting post 2 located at the corner of the steel platform 1, away from the wall corner, is in the most unstable position, i.e., far from the wall support. When construction workers walk on the steel platform 1 or place items on it, the steel platform 1 is most prone to tilting or wobbling at this location. The limiting post 2 at this location, through contact and friction with the inner wall of the flue opening, effectively prevents the steel platform 1 from shifting or tilting at this point. By installing the limiting post 2, even if the construction workers stand on the side of the steel platform 1 away from the corner of the wall, the limiting post 2 can ensure that the steel platform 1 remains stable and will not tilt or shake, thus providing a safer working environment for the construction workers.

[0029] Furthermore, the limiting post 2 is an angle iron, which is welded and fixed to the lower surface of the steel platform 1. First, the angle iron has high rigidity and strength, and can withstand large lateral forces without deformation, ensuring stable contact with the inner wall of the flue opening; second, the angle iron is a common type of construction steel, inexpensive and readily available in the market, which can greatly reduce the manufacturing cost of the entire device; third, the angle iron is fixed to the steel platform 1 by welding, which not only simplifies the construction process but also ensures a firm and reliable connection, capable of withstanding various stresses during repeated use.

[0030] In some embodiments, refer to Figure 2 The length of the limiting post 2 is greater than the height of the inner wall surface. The bottom end of the limiting post 2 is provided with a locking part 21, which is an outwardly bent L-shaped structure. When the steel platform 1 covers the flue opening, the locking part 21 engages with the bottom of the inner wall surface. The limiting post 2 is designed to be longer than the inner wall surface, allowing its bottom end to extend below the inner wall surface. The bottom end is provided with an outwardly bent L-shaped locking part 21. When the steel platform 1 covers the flue opening, this L-shaped locking part 21 engages with the bottom of the inner wall surface of the flue opening. This structural design not only provides stability through friction but also provides additional fixing through mechanical locking. For example, at a residential building construction site, after the construction workers install the steel platform 1 in place, the L-shaped locking part 21 at the bottom of the limiting column 2 will automatically engage with the bottom of the inner wall of the flue. Even if subjected to a large external force, the steel platform 1 will not easily shift or lift. This double fixing mechanism greatly improves the safety performance of the entire enclosure device.

[0031] In some embodiments, a temporary window 11 is provided in the middle of the steel platform 1, and a cover plate 12 is provided at the temporary window 11. The cover plate 12 is hinged to the steel platform 1 via a hinge 13, and the cover plate 12 can be rotated to open or close the temporary window 11. This temporary window 11 allows construction workers to temporarily open and close the flue without completely removing the entire steel platform 1. For example, during residential building construction, when materials need to be placed into the flue or for inspection, construction workers only need to rotate the cover plate 12 to open the temporary window 11 to complete the operation, and then rotate the cover plate 12 back to the closed position after the operation is completed. Connecting the cover plate 12 via the hinge 13 not only makes the operation simple and quick, but also avoids the risk of the cover plate 12 falling off during use, greatly improving construction efficiency and safety.

[0032] Furthermore, refer to Figure 1The cover plate 12 includes two split-opening sub-cover plates 12, which are respectively hinged to the opposite side edges of the temporary window 11 via hinges 13. Each sub-cover plate 12 has a first handle 14 at its free end. When flue inspection or material feeding is required, construction personnel can choose to open a single sub-cover plate 12 or both sub-cover plates 12 simultaneously, depending on the actual needs. The opening and closing actions can be easily controlled by the first handle 14. This split-opening design not only reduces the weight of a single cover plate 12, making operation more labor-saving, but also allows for adjustment of the opening size according to operational needs. At the same time, the design of two sub-cover plates 12 can better ensure the tightness and stability of the window.

[0033] Furthermore, a second handle 15 is provided on the upper surface of the platform along the outer periphery of the temporary window 11. The second handle 15 provides a reliable gripping point for construction workers when moving the entire steel platform 1. The distribution of the second handle 15 along the outer periphery of the temporary window 11 not only allows construction workers to obtain a better point of leverage when moving the steel platform 1, but also serves as a support point when opening the temporary window 11.

[0034] In some embodiments, buffer elements 3, which are rubber strips, are provided at the two edges of the steel platform 1 near the wall. These buffer elements 3 are fixed to the steel platform 1 by adhesive or bolts. When the steel platform 1 is installed in place, the L-shaped locking part 21 at the bottom of the limiting post 2 engages with the bottom of the inner wall of the flue opening, while the rubber strip contacts the wall to provide cushioning. This not only ensures the stability of the steel platform 1 through the locking mechanism but also reduces direct contact with the wall through the cushioning effect of the rubber strip. In residential building construction sites, this design ensures both the sealing between the steel platform 1 and the wall and provides good cushioning protection. Combined with the convenient opening mechanism of the temporary window 11, the practicality and safety of the entire device are significantly improved.

[0035] Furthermore, the buffer 3 is disposed along the two edges of the steel platform 1 near the wall, or at the three corners of the steel platform 1 near the wall. It is understood that both methods provide effective buffering protection. The continuous edge placement provides a larger area for buffering and sealing, while the corner placement is more material-efficient and easier to install. In residential construction sites, when the steel platform 1 needs to frequently open the temporary window 11 for work, regardless of the chosen method, the rubber strip can be securely installed on the steel platform 1 by adhesive or bolts, providing necessary buffering protection and effectively preventing direct collisions and wear between the steel platform 1 and the wall.

[0036] In some embodiments, a balancer 4 is provided on the steel platform 1. The balancer 4 has a base and is fixed to the upper surface of the steel platform 1 by the base. It is understood that when construction workers need to perform flue inspections or other operations through the temporary window 11 at a residential building construction site, the balancer 4 can help maintain the levelness of the entire device and remain stable even when the steel platform 1 is under heavy load on one side. Especially when the temporary window 11 needs to be opened frequently or heavy objects need to be moved, the balancer 4 can effectively prevent the steel platform 1 from tilting or swaying.
