Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a fire connection bucket and a fire connection bucket component. Background Art

[0002] A large amount of welding work is required in construction. During welding, a fire hopper needs to be set up to catch the fallen slag, welding flow or waste chips from the bottom of the welding point to achieve fire prevention.

[0003] There are various types of existing fire-catching buckets. The Chinese utility model patents with announcement numbers CN220372480U and CN219852786U both disclose fire-catching buckets for column welding, which need to have a middle socket to avoid the column; the Chinese utility model patent with announcement number CN218362854U discloses a fire-catching bucket with a notch, which is suitable for welding columns and wall columns; announcement numbers CN220161579U, CN220196703U and CN114918583A disclose some fire-catching buckets with relatively regular outer contours, which are suitable for hanging under beams or ceilings, and these fire-catching buckets all have a folding function for portability.

[0004] It can be seen that in different welding scenarios such as columns, wall columns, ceilings and beams, different types of fire-jointing buckets are needed, such as those with middle sockets, side notches, and complete outlines. In construction, the above-mentioned different welding scenarios often occur. In this case, one or two fire-jointing buckets cannot be adapted to multiple scenarios or cause unchanged use, resulting in construction difficulties, and poor jointing effects and fire hazards; or multiple fire-jointing buckets are configured, but this will increase the difficulty of manufacturing and transportation. Utility Model Content

[0005] The first purpose of the utility model is to provide a welding bucket that can better cope with various actual welding scenes.

[0006] The second purpose of the utility model is to provide a welding bucket assembly that can better cope with various actual welding scenarios.

[0007] The first purpose of the utility model provides a fire connection bucket comprising a plurality of fire connection units spliced ​​to each other, and the shape of the fire connection bucket can be changed by changing the splicing method of the plurality of fire connection units; it also comprises a connecting piece for detachable connection between two adjacent fire connection units, and / or, it also comprises a connecting structure arranged on the fire connection unit for detachable connection between two adjacent fire connection units.

[0008] Another further solution is that the outer contour of the fire connection unit is square, and the fire connection bucket can be spliced ​​into a shape with a complete contour, a shape with a central hole, and a shape with a notch; or, the outer contour of the fire connection unit is a fan ring, and the fire connection bucket in one shape includes at least two fire connection units spliced ​​along the circumferential direction of its own circle center, and the fire connection bucket in another shape includes at least two fire connection units spliced ​​along the radial direction of its own circle center; or, the side contour of the fire connection unit is an inverted arch shape, and the fire connection bucket in one shape includes at least two fire connection units spliced ​​along the circumferential direction of its own circle center, and the fire connection bucket in another shape includes at least two fire connection units spliced ​​along the axial direction of its own circle center.

[0009] As can be seen from the above scheme, the utility model decomposes the previously integrated fire-connecting bucket into multiple fire-connecting units through modularization, and then splices the fire-connecting units. By changing the splicing method of these fire-connecting units, the fire-connecting bucket can present different final forms. For example, square fire-connecting units can be spliced ​​into fire-connecting buckets with central holes, gaps, and complete contours, which can meet the fire-connecting requirements of actual scenarios such as welding around columns, welding on both sides of wall columns, and welding of ceilings and beams. For example, fan rings and anti-arch fire-connecting units can well meet the fire-connecting requirements of vertical and horizontal cylindrical beam-related scenarios, and the fire-connecting buckets assembled according to the scenarios have a higher degree of coordination with the scenarios. Therefore, in a construction project, only a few sets of modular fire-connecting buckets need to be configured to meet the use requirements of various scenarios, reduce construction costs, reduce construction difficulty and transportation difficulty, and at the same time better ensure construction fire safety.

[0010] A further solution is that the fire connection unit includes a connecting wall, the connecting piece is connected between two connecting walls, and / or the connecting structure is arranged on the connecting wall; the fire connection unit includes a side wall, the side wall serves as a connecting wall, or the fire connection unit is arranged in a plate shape, and the fire connection unit includes a bottom wall, and the bottom wall serves as a connecting wall.

[0011] As can be seen from the above, under the premise of satisfying the requirements of various scene placement requirements and forming a fire-connecting bucket with different forms by splicing these fire-connecting units, it is necessary to further consider how to set up the fire-connecting unit. The fire-connecting unit with side walls becomes a container unit itself, which can better ensure the fire-connecting effect. At this time, it is more convenient to connect the two side walls together; in addition, setting up the side walls requires more materials. For this reason, the fire-connecting unit can also be set as a plate without side walls in all directions to reduce the molding materials. At this time, it is more convenient to connect the two bottom walls together.

[0012] A further solution is that the connecting member is movably connected to the connecting wall, and the movable end of the connecting member is detachably connected to the connecting structure on another connecting wall; or, the connecting member is arranged in a detachable form; or, the two connecting structures of two adjacent connecting walls are detachably connected.

[0013] As can be seen from the above, further consideration needs to be given to how to make assembly more convenient at the construction site. The connecting piece can be set in the form of a vertical swing arm or a horizontal rotary arm. No matter the two plate-shaped fire connection units are butt-jointed, overlapped or buckled, the connecting piece of one fire connection unit can be buckled onto the other fire connection unit after swinging to achieve connection. The connecting piece can also be designed in the form of a detachable clamp or lock. The clamp can clamp the two adjacent side walls and the two sides of the lock can be buckled onto the two bottom walls at the same time. Of course, it is also possible to directly form a concave-convex matching connection structure on the two adjacent side walls or the two overlapping bottom walls to achieve connection matching while completing the adjacent or overlapping connection. Therefore, there are various ways to achieve the detachable connection between two adjacent fire connection units. For example, one end of the movable connection of the swing arm and the rotary arm is always connected to one fire connection unit, which is convenient for storage and not easy to lose; the detachable connection parts such as locks or clamps are simpler to disassemble and assemble, reducing the construction difficulty; and directly using the connection structure on the connecting plate to achieve connection is more conducive to reducing the number of components and reducing costs.

[0014] A further solution is that the ignition connection unit includes a side wall located on its periphery, and the side wall includes a lower extension portion, which extends to below the bottom wall of the ignition connection unit, and a lower support position is formed between the lower extension portion and the bottom wall.

[0015] As can be seen from the above, in some cases, in addition to hoisting, the fire bucket also needs to be supported by support rods to improve the stability. Generally, the bottom of the fire bucket is flat, and the support rods lack supporting force positions, which affects the support stability, or some connecting components need to be assumed on the top of the support rods, which increases the design cost and difficulty. Under this setting, it is only necessary to support the support rods to the lower support position, especially the support rods generally choose a diagonal support posture. At this time, the support rods will be able to be restricted to the angular position formed by the two vertical side walls and the bottom wall, which plays a good positioning role and improves the support stability. More importantly, it is only necessary to slightly raise the welding position of the bottom wall when connecting the bottom wall and the side walls together, and the technical effect can be achieved without increasing any workload.

[0016] A further solution is that, based on the fire connection unit being arranged in a plate shape, the fire connection bucket further comprises a side stop unit, the side stop unit being arranged on the outer edge of the fire connection bucket, and the side stop unit is detachably connected to the fire connection unit.

[0017] As can be seen from the above, if the fire connection unit is not provided with a side wall, in order to prevent the welding flow waste and slag from falling from the side edge for the second time, it is better to add a side stop unit. Similarly, the side stop unit and the fire connection unit can also be detachably connected through the cooperation of some connecting parts and connecting structures.

[0018] A further solution is that the ignition unit is connected to the side stop unit by a connecting structure provided thereon and / or a connecting piece connected thereto.

[0019] As can be seen from the above, this arrangement can minimize the amount of processing on the ignition unit and the increase in parts, simplify the structural design, and reduce the difficulty of production and installation.

[0020] The second object of the utility model provides a fire connection bucket assembly comprising a fire connection bucket and a connecting rod, one end of the connecting rod is connected to the fire connection bucket; the fire connection bucket adopts the above-mentioned fire connection bucket, and the length of the connecting rod is adjustable.

[0021] It can be seen from the above scheme that, as described above, based on the setting of modular fire-catching buckets, only a few sets of modular fire-catching buckets need to be configured in a construction project to meet the use requirements of various scenarios, reduce construction costs, reduce construction difficulty and transportation difficulty, and at the same time better ensure construction fire safety. On the other hand, the installation and fixation of the fire-catching bucket also needs to be considered. Generally, the fire-catching bucket will be hoisted by several connecting rods, and the top of the support rod is fixed to the appropriate position of the scene by tying, bonding or screwing. In more cases, the several connecting rods are not in a state of being parallel and vertical to each other, so it is easy to make the fire-catching bucket suspended by them in a non-horizontal posture, which may not only cause the problem of secondary falling of waste scraps and slag, but also the unstable stress state will cause the fire-catching bucket itself to fall off. Therefore, the utility model also designs the connecting rod to be in a length-adjustable form. After installing these connecting rods, the length of multiple connecting rods is adjusted to achieve the horizontal calibration of the fire-catching bucket.

[0022] A further solution is that the connecting rod includes a first rod end connecting component arranged at its extended end; the first rod end connecting component is connected to the connecting structure, or the first rod end connecting component is connected to the connecting piece.

[0023] As can be seen from the above, directly using the connecting structure or connecting piece on the fire receiving bucket as the structure connected to the connecting rod can further reduce the amount of processing on the fire receiving unit and minimize the increase in parts, simplify the structural design, and reduce the difficulty of production and installation.

[0024] Another further solution is that the connecting rod includes a rod seat, a first rod member and a second rod member, the first rod member and the second rod member are both connected to the rod seat and extend in opposite directions; at least one of the first rod member and the second rod member is configured as an adjustable rod member, and the adjustable rod member is provided with a plurality of locking structures arranged along its own length direction; the rod seat includes a seat body and a rod locking member, a rod insertion hole is provided on the seat body, the rod locking member is movably connected to the seat body, the rod locking member cooperates with the locking structure and limits the adjustable rod member in the length direction of the adjustable rod member.

[0025] As can be seen from the above, while ensuring that the length of the connecting rod is adjustable, it is also necessary to ensure that the adjusted connecting rod can be stably maintained in the current state. Under this setting, when the rod locking piece is in the unlocked position, the adjustable rod can be moved relative to the rod seat to achieve adjustment; after the adjustment is completed, the staff only needs to slightly operate the rod locking piece to make it reach a position that matches the locking structure. Since the connecting rod generally only bears one of the traction force or the extrusion force, in fact, the rod locking piece can meet the use requirements by locking the adjustable rod in one direction.

[0055] First embodiment of the fire bucket assembly

[0056] See also Figures 1 to 3 The fire connection bucket assembly of this embodiment includes a fire connection bucket 1000, and the fire connection bucket 1000 includes a plurality of fire connection units 1 spliced ​​to each other, and the shape of the fire connection bucket 1000 can be changed by changing the splicing method of the plurality of fire connection units 1.

[0057] The outer contour of the fire receiving bucket unit 1 of this embodiment is square. Figure 1 As shown, by splicing a plurality of fire connection units 1 in a first manner, the fire connection bucket 1000 can be formed into a first form with a complete outline, in which the bottom surface of the fire connection bucket is complete without a gap; Figure 2 As shown, by splicing a plurality of fire connection units 1 in a second manner, the fire connection bucket 1000 can be formed into a second form with a central hole 1001; Figure 3 As shown, by splicing a plurality of fire connection units 1 in a third manner, the fire connection bucket 1000 can be formed into a third form with a side notch 1002 .

[0058] See also Figure 4 In this embodiment, the fire connection unit 1 includes a bottom wall 11 and a side wall 12 connected to the edges of the bottom wall 11 in a square frame shape. Thus, an accommodation space 110 for fire connection is formed between the inner periphery of the side wall 12 and the upper part of the bottom wall 11, so that the slag, welding flow or waste caught by the fire connection unit 1 is retained in the accommodation space 110 to avoid the problem of secondary falling. Further, as Figure 4 As shown, the side wall 12 in this embodiment includes a lower extension portion 122, which extends to below the bottom wall 11 of the ignition unit 1. A downwardly open lower support position 120 is formed between the lower extension portion 12 and the bottom wall 11, and the lower support position 120 is used to cooperate with the connecting rod to achieve a stable support effect.

[0059] See also Figure 5In this embodiment, the top of the side wall 12 of the fire connection unit 1 is formed with a frill 121 bent toward its own accommodation space 110. Furthermore, any two adjacent fire connection units 1 in the fire connection bucket 1 are fixedly connected to each other through the cooperation of the clamp 299 and the frill 121. The clamp 299 is a closed U-shaped clamp. After the clamp 299 clamps the two frills 121 of the two adjacent side walls 12, not only the two side walls 12 are firmly connected together, but also the anti-loosening effect can be achieved well under the closing effect of the clamp 299. Furthermore, since the side wall 12 extends upward and downward relative to the bottom wall 11, the frill 121 can be set not only on the upper edge of the side wall 12, but also on the lower edge of the lower extension 122 of the side wall 12. In this way, the clamp 299 can be selected to be connected between the upper sides of the two fire connection units 1, or between the lower sides of the two fire connection units 1. Among them, the clamp 299 is also a connecting member in this embodiment, the frill 121 is a connecting structure in this embodiment, and the side wall 12 is a connecting wall in this embodiment.

[0060] See also Figure 6 In this embodiment, some clamps 299 are welded to the connecting rod 2 ( Figures 7 to 10 As shown in the figure, the clamping connection assembly 29 on the connecting rod 2 can be used to achieve a fixed connection with the connecting rod 2, and then the clamp 299 can be used to achieve the lifting and support of the fire bucket 1000.

[0061] See also Figure 7 , Figure 8 , Fig. 9 as well as Figure 1 ,exist Figure 7 The welding scene of the ceiling 911 shown and Figure 8 In the welding scene of the wall 912 shown, and in Fig. 9 In the welding scenario of the crossbeam 913 shown in the figure, the required fire bucket does not need to be provided with features such as a center hole or a notch to match the scenario, so it can be selected to adopt Figure 1 The fire receiving bucket 1000 with a complete outline as shown is used for receiving fire, and further, the fire receiving bucket assembly of the utility model further includes a connecting rod 2, Figures 7 to 9 In the illustrated scenario, the fire bucket 1000 is hoisted using four connecting rods 2, wherein: Figure 7 and Figure 8 In the scenario, the top of the connecting rod 2 is fixed to the ceiling 911 and the wall 912 by bonding, and Fig. 9 In the scenario shown, the top end of the connecting rod 2 is fixed to the crossbeam 913 by bundling.

[0062] See also Fig.10 and Figure 3 In the welding scenario of wall column 914, it is better to use Figure 3 The fire connection is performed by using the fire connection bucket 1000 with a notch 1002. The width of the notch 1002 can be greater than the width of the column 914. Since welding is generally performed on one side, when welding on one side, the fire connection bucket 1000 is adjusted horizontally until the inner side of the notch 1002 is in contact with the welding side column surface. In addition, the top end of the connecting rod 2 is bonded to the wall.

[0063] What is not shown is that in the welding scenario of non-wall columns, it is better to use Figure 2 The fire receiving bucket 1000 with the center hole 1001 shown is used for receiving fire, and the top end of the connecting rod 2 can be fixed to the non-wall column not only by bonding, but also by bundling.

[0064] The connecting rod 2 is described below. Figures 7 to 10 In the four scenes shown, the fire-catching bucket 1000 is hoisted by four groups of connecting rods 2. However, the four groups of connecting rods 2 are neither parallel nor vertical. The utility model also designs the connecting rods 2 to be length-adjustable. After installing these connecting rods 2, the length of multiple connecting rods 2 is adjusted to achieve basic horizontal calibration of the fire-catching bucket 1000. In addition, it can be seen that the four groups of connecting rods 2 have different lengths, and the most suitable connection methods in different scenes are also different.

[0065] To this end, the connecting rod 2 of this embodiment is configured to be able to form sets of different forms by selecting different parts for assembly. Fig.11 and Fig.14 The connecting rod 2 includes a main body portion and a first rod end connecting member and a second rod end connecting member respectively installed at both ends of the main body portion.

[0066] The optional components of the main body include a rod seat 20, an adjustable rod 22, and a fixed rod 24. Fig.11 , two adjustable rods 22 and a rod base 20 can be assembled into a first form, see Fig.14 Alternatively, two adjustable rods 22, two rod seats 20 and a fixed rod 24 may be selected to form a second form having a longer length.

[0067] The first rod end connecting member is used to be fixedly connected to the fire bucket 1000. Figure 6 as well as Fig.11 The clamping connection assembly 29 shown; wherein the second rod end connecting member is used to connect with the scene, the second rod end connecting member is shown Fig.13 The adhesive connection assembly 28 is shown as well as Fig.15 and Fig.16 The strap connection assembly 27 is shown.

[0068] See again Fig.11 and Fig.14 In the first form and the second form, the main body part includes at least a first rod and a second rod, and the first rod and the second rod are both connected to the rod seat and extend in opposite directions; at least one of the first rod and the second rod is set as an adjustable rod 22, so that the connecting rod 2 can be fully extended and the length can be adjusted.

[0069] Recombination Fig.12 The rod seat 20 includes a seat body 21 and a plurality of rod locking members 23 rotatably mounted on the seat body 21. The seat body 21 is provided with a first rod insertion hole 2101, a fixing hole 2102 and a second rod insertion hole 2101 arranged in sequence along its length direction. The fixing hole 2102 of this embodiment is a screw hole. Both the rod insertion hole 2101 and the fixing hole 2102 penetrate the rod seat 20 along the thickness direction of the rod seat 20. The swing-rod-shaped rod locking member 23 is connected to the opening edge of the rod insertion hole 2101, and in the length direction of the seat body 21, the left and right sides of the opening of each rod insertion hole 2101 are connected with a rod locking member 23, and in the thickness direction of the seat body 21, the edges of the opening on both sides of each rod insertion hole 2101 are connected with two rod locking members 23.

[0070] See also Fig.12 The adjustable rod 22 is provided with a plurality of locking structures arranged along its length direction. In the present embodiment, the locking structure is an annular groove 221 with a certain inclination surrounding the adjustable rod 22. The front and back of the adjustable rod 22 can be distinguished according to the inclination direction of the annular groove 221. During installation, the two adjustable rods 22 are respectively inserted into the two rod insertion holes 2101 in opposite directions. Thereafter, the rod locking piece 23 can be swung and inserted into the annular groove 221 through operation, and the adjustable rod 22 is restricted in one direction in the length direction of the adjustable rod 22.

[0071] In fact, the rod locking member 23 disposed on the first side of the thickness direction of the rod seat 20 is used to limit the position of one adjustable rod 22, while the rod locking member 23 disposed on the second side of the thickness direction of the rod seat 20 is used to limit the position of the other adjustable rod 22. Fig.12 As shown, the adjustable rod 22 on the left side of the figure is engaged with the rod locking piece 23 on the lower side of the rod seat 20, and the adjustable rod 22 on the right side of the figure is engaged with the rod locking piece 23 on the upper side of the rod seat 20. In this way, when the top end of the adjustable rod 22 on the left side of the figure is connected to the scene and the bottom end of the adjustable rod 22 on the right side of the figure is connected to the fire receiving bucket 1000, the connecting rod 2 can provide traction for the fire receiving bucket 1000. On the contrary, the two adjustable rods 22 can also be used to limit the change of direction, so that the connecting rod 2 becomes a support rod that can withstand the gravity of the fire receiving bucket 1000 from below.

[0072] Recombination Figures 7 to 10 When the horizontality of the fire bucket 1000 needs to be adjusted and the lengths of the four connecting rods 2 of the hoisting fire bucket 1000 need to be adjusted separately, the rod locking piece 23 can be opened to restore the state of relative movement between the adjustable rod 22 and the rod seat 20. At this time, the length of the connecting rod 2 is adjustable.

[0073] See also Fig.14 In the second form, the opposite ends of a fixed rod 24 are respectively threadedly connected to the fixing holes 2102 of the two base bodies 21, and the two base bodies 21 are each connected to an adjustable rod 22. Of course, in other forms, the main body of the connecting rod 2 includes only one rod seat 20, one adjustable rod 22 and one fixed rod 24. In this case, the first rod end connecting member and the second rod end connecting member are respectively connected to the ends of the adjustable rod 22 and the ends of the fixed rod 24.

[0074] See also Figure 6 and Fig.11 In this embodiment, the clamping connection assembly 29 includes a first ball joint 297, a second ball joint 298 and the above-mentioned clamp 299. The first ball joint 297 and the second ball joint 298 are movably connected in the form of a ball joint. The first ball joint 297 is provided with a screw hole 2970 and the end of the adjustable rod 22 is provided with a threaded section. The first ball joint 297 is fixedly installed on the adjustable rod 22 through the cooperation of the screw hole 2970 and the threaded section, and the clamp 299 is an integral part with the second ball joint 298. This arrangement allows the connection rod 2 and the fire bucket 1000 to have relative freedom of movement in multiple directions.

[0075] See also Fig.11 and Fig.13 The bonding connection component 28 includes a third ball joint 288, a fourth ball joint 289 and a bonding seat 287. The third ball joint 288 and the fourth ball joint 289 are movably connected in the form of a ball joint. A screw hole 2880 is provided on the third ball joint 288. The third ball joint 288 is fixedly installed on the adjustable rod 22 through the screw hole 2880 and the threaded section at the end of the adjustable rod 22. The bonding seat 287 is an integral part with the fourth ball joint 289. The bonding connection component 28 is bonded to the scene through the bonding seat 287. A sunken receiving pool 2870 is provided on the bonding seat 287. The receiving pool 2870 is used to fill glue or other adhesives.

[0076] See also Fig.15 and Fig.16, and the other second rod end connection component - the strap connection component 27 includes a fifth ball joint 278, a sixth ball joint 279, a strap buckle 277 and a strap 26. The fifth ball joint 278 and the sixth ball joint 279 are movably connected in the form of a ball joint. The fifth ball joint 278 is provided with a screw hole. The fifth ball joint 278 is fixed to the adjustable rod 22 through the screw hole thereon and the threaded section at the end of the adjustable rod 22. The strap buckle 277 and the sixth ball joint 279 are an integrated part. The strap buckle 277 includes a snap-fit ​​ball head 276 and a swing buckle 2771 swingably connected to the strap buckle 277.

[0077] The strap 26 comprises a base 260, a clamping seat 261, an end buckle seat 263 and a rotating buckle 264. The flexible base 260 extends along the extension direction of the strap 26. A plurality of clamping seats 261 are arranged at intervals on the surface side of the strap 26 along the extension direction of the strap 26. The clamping seat 261 is provided with a clamping slot 2610 which penetrates along the extension direction of the strap 26 and opens a narrow opening toward the surface side of the strap 26. The inner contour of the clamping slot 2610 is "C" shaped. The root of the clamping seat 261 is connected to the base 260. The root of the clamping seat 261 is provided with a groove 262. The concave direction of the groove 262 is perpendicular to the protruding direction of the clamping seat 261 and the groove 262 penetrates along the width direction of the clamping seat 261. The groove 262 and the interval between the two clamping seats 261 are mutually connected and perpendicular to each other, so that an inverted "T"-shaped clamping position is formed between the two clamping seats 261.

[0079] Second embodiment of the fire bucket assembly

[0080] See also Fig.17In this embodiment, the connecting member is a "door"-shaped clip 14, and a first through hole 141 is provided on the opposite side arms of the clip 14. The side wall 13 of this embodiment serves as a connecting wall, and the connecting structure is a first column pin 131 fixedly welded on the side wall 13. The first column pin 131 extends horizontally and is parallel to the side wall 13 to which it is connected, and a certain interval is provided between the first column pin 131 and the side wall 13 to which it is connected.

[0081] In this way, when the two ignition connection units are spliced ​​and the two side walls 13 are adjacent, the clip 14 is inserted downward so that the two side walls 13 are restricted between the opposite side arms of the clip 14, and then the clip 14 is pushed horizontally to allow the two first pins 131 to be respectively inserted into the two first through holes 141 of the opposite side arms of the clip 14, thereby realizing the detachable connection of the two adjacent ignition connection units.

[0082] The third embodiment of the fire bucket assembly

[0083] See also Fig.18 In this embodiment, the first frill 151 and the second frill 152 are respectively provided on the upper edge and the lower edge of the side wall 15 of the fire connection unit, wherein the inner diameter of the first frill 151 and the outer diameter of the second frill 152 are in a matching relationship, and the first frill 151 extends beyond a semicircle. In addition, the first frill 151 in this embodiment is rolled outward and the second frill 152 is rolled inward. The first frill 151 and the second frill 152 are both connection structures of this embodiment, and a connection piece is not required in this embodiment.

[0084] In this way, when splicing two adjacent fire connection units, the two adjacent fire connection units need to be arranged in an upright and an inverted manner, and then the first hem 151 on one fire connection unit can be buckled on the second hem 152 of the other fire connection unit, and the elastic deformation ability of the first hem 151 can be used to make the first hem 151 and the second hem 152 form a stable buckling relationship.

[0085] Fourth embodiment of the fire bucket assembly

[0086] See also Fig.19 Similar to the third embodiment, this embodiment also has a first frill 161 and a second frill 162 respectively disposed on the upper edge and the lower edge of the peripheral wall 16 . The difference is that the second frill 162 in this embodiment is rolled outward.

[0087] Fifth embodiment of the fire bucket assembly

[0088] See also Fig. 20 and Fig.21 In this embodiment, the outer contour of the fire connection unit 17 is a fan ring, and the fire connection unit 17 included in the fire connection bucket includes a plurality of fire connection units 17 with different inner and outer diameters. Fig. 20As shown, the fire-connecting bucket in this form includes two fire-connecting unit components 17 spliced ​​along the circumferential direction of its own circle center, and includes at least one fire-connecting unit component 17 spliced ​​along the radial direction of its own circle center.

[0089] Continuing with the fifth embodiment, in other embodiments of the fire-receiving bucket assembly using a fire-receiving unit component of a fan ring, no splicing is performed in the radial direction and only one fire-receiving unit component is included, or no splicing is performed in the circumferential direction and only one fire-receiving unit component is included.

[0090] In fact, some columns are cylindrical, in which case the fire-connecting bucket formed by the square fire-connecting unit 1 in the first embodiment is not applicable. However, the fire-connecting unit 17 of the fan ring of this embodiment can be assembled into a fire-connecting bucket with a circular inner side surface, which can be more closely fitted with the outer wall of the circular column to achieve a better fire-connecting effect.

[0091] Furthermore, the square or plane column and the rectangular fire-connecting bucket can maintain a good fit with each other without considering the size, while when connecting the round column, a more ideal fit can only be achieved when the inner diameter of the fire-connecting bucket is close to or equal to the outer diameter of the round column. Therefore, the fire-connecting bucket of this embodiment includes a plurality of fire-connecting units 17 with different inner diameters and / or outer diameters.

[0092] like Fig.21 In the example, the plurality of contact units 17 with different inner and outer diameters include a first contact unit 171, a second contact unit 172 and a third contact unit 173, wherein the outer diameters of the second contact unit 172 and the third contact unit 173 are equal to the inner diameter of the first contact unit 171, and the inner diameter of the third contact unit 173 is smaller than the inner diameter of the second contact unit 172. Thus, when the contact units 17 are selected for assembly, the first form a1 formed by radially splicing the first contact unit 171 and the second contact unit 172 has a larger inner diameter, and the second form a2 formed by radially splicing the first contact unit 171 and the third contact unit 173 has a smaller inner diameter.

[0093] On the other hand, considering the manufacturing and transportation costs, the multiple replaceable and assembled ignition connection units placed inside will tend to be equipped in a manner of step-by-step changes in the inner diameter; however, the outer diameter specifications of the circular columns encountered in the scene are various, so the inner diameter of the ignition connection bucket may not match the outer diameter of the circular column. In this case, a ignition connection bucket with the closest and slightly larger diameter can be assembled. After the inner side of the ignition connection bucket is tangent to the surface of the circular column, the gap between the ignition connection bucket and the circular column can be filled with heat-resistant material.

[0094] in addition, Fig.21Taking the first contact unit 171, the second contact unit 172 and the third contact unit 173 as examples, the first contact unit 171, the second contact unit 172 and the third contact unit 173 are used as a unit group, the first contact unit 171 is used as the basic unit in the unit group, and the second contact unit 172 and the third contact unit 173 are used as replacement units in the unit group. In order to facilitate the selection and assembly, it is better to equip multiple unit groups with different outer diameters according to the diameter area range, and each unit group includes a basic unit and at least two replacement units.

[0095] Similarly, three or more fire connection units with matching inner diameters and outer diameters can also be radially spliced. In addition, for the connection between the fire connection units 17, the side walls of the arc are preferably Fig.17 The clip 14 shown is connected with the pin, and the flat side walls can be Figure 5 , Fig.17 , Fig.18 or Fig.19 Connect as shown.

Fig. 22 In the illustrated form, the fire-connecting bucket includes two fire-connecting unit components 18 spliced ​​axially along the center of the circle. Of course, other forms of fire-connecting buckets include at least two fire-connecting unit components 18 spliced ​​circumferentially along the center of the circle. The fire-connecting bucket spliced ​​by the fire-connecting unit components 18 is suitable for hoisting under the circular beam for fire connection.
