Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a detachable and reusable steel column welding protection device. Background Technology

[0002] For example, Chinese utility model patent publication number CN 212507432 U discloses a novel fire-collecting basin, comprising four collecting plates. Each of the four collecting plates has a vertical support fixedly installed on its top, and the four vertical supports are interconnected to form a square structure. The four collecting plates are also interconnected, and the bottom of each collecting plate has a single slag-discharging port fixedly installed. The collecting plates are inclined at a 5° angle. One end of a hanging rope is fixedly installed at each of the four corners of the square structure formed by the four vertical supports, and the other end of two hanging ropes on the same side is fixedly installed with a magnet. This method uses a magnet for fixation. If the magnet is too small, the suction force is weak and unstable; if the magnet is too large, it is too heavy, the suction force is too strong, and it is difficult to remove, which is very inconvenient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a detachable and reusable steel column welding protection device, which uses water pressure to fix the fire receiving plate to the steel column and can be easily removed after drainage, which is very convenient.

[0004] To solve the above problems, a detachable and reusable steel column welding protection device is adopted, which includes:

[0005] The support ring is arranged around the steel column and extends outward from bottom to top in an oblique manner. It is a split type, which includes a first support ring body and a second support ring body. Both ends of the first support ring body and the second support ring body are fixed with radial splicing end plates.

[0006] A bolt and nut assembly that passes through and fastens two adjacent splicing end plates;

[0007] A guide ring plate is arranged around the steel column, extending vertically upwards and downwards, and located below the welding position of the steel column; it is fixed to the lower side of the support ring, and is a split type, comprising a first guide body and a second guide body, both ends of which are fixed to the splicing end plate.

[0008] A limiting ring plate is arranged around the steel column and spaced below the support ring to form a placement groove. Its lower side is fixed to the guide ring plate. It extends obliquely outward from bottom to top. It is a split type and includes a first limiting body and a second limiting body. The ends of the first limiting body and the second limiting body are spaced apart to form an outlet.

[0009] The fire hose is coiled and placed in a storage trough, with both ends extending from the outlet. One end is equipped with a water inlet connector, and the other end is equipped with a first stop valve.

[0010] With this structure, the bolt and nut assembly fastens the two semi-circular first and second ring bodies to form a large ring around the steel column, and the welding slag falls into the ring.

[0011] The guide ring plate moves up and down along the steel column to find a fixed position;

[0012] After the fire hose is installed in the placement trench, the inlet connector is connected to the water pump. The water pump pumps water, and the fire hose quickly expands in the placement trench, forming radial pressure between the limiting ring plate and the guide ring plate, which is applied to the steel column and increases the friction between the guide ring plate and the steel column. The first stop valve at the other end of the fire hose is closed to prevent water from flowing out. When disassembly is required, the water pump is turned off and the first stop valve is opened to drain the water. The fire hose not only serves to fasten the hose but also cools the welding slag to ensure welding safety.

[0013] As a further improvement of this utility model, a second water stop valve is also installed on the fire hose behind the water inlet connector.

[0014] Once the fire hose has expanded and tightened, the second stop valve can be closed, and the water pump can be shut off to maintain the tightened state.

[0015] As a further improvement of this utility model, a rib is also provided between the support ring and the guide ring plate.

[0016] This structure prevents the fire hose from pressing the support ring and guide ring plate tightly, thus reducing the space for receiving slag.

[0017] This invention utilizes water pressure to secure the fire-receiving plate to the steel column, and it can be easily removed after drainage, making it very convenient. Attached Figure Description

[0030] Example 1

[0031] like Figures 1-3 As shown, a detachable and reusable steel column welding protection device includes:

[0032] The support ring 1 is arranged around the steel column 2 and extends outward from bottom to top in an oblique manner. It is a split type and includes a first support ring body 101 and a second support ring body 102. Both ends of the first support ring body 101 and the second support ring body 102 are fixed with radial splicing end plates 103.

[0033] Bolt and nut assembly 3, which passes through and fastens two adjacent splicing end plates 103;

[0034] The guide ring plate 4 is arranged around the steel column 2, extends vertically upward and downward, and is located below the welding position of the steel column 2; it is fixed to the lower side of the support ring 1, and is a split type, which includes a first guide body 401 and a second guide body 402, both ends of the first guide body 401 and the second guide body 402 are fixed to the splicing end plate 103.

[0035] The limiting ring plate 5 is arranged around the steel column 2 and spaced below the support ring 1 to form a placement groove 6. Its lower side is fixed on the guide ring plate 4. It extends outward from bottom to top in an oblique manner. It is a split type and includes a first limiting body 501 and a second limiting body 502. The ends of the first limiting body 501 and the second limiting body 502 are spaced apart to form an outlet 503.

[0036] Fire hose 7 is coiled and placed in placement trough 6, with both ends extending from outlet 503. One end is equipped with water inlet connector 701, and the other end is equipped with first stop valve 702.

[0037] With this structure, the bolt and nut assembly 3 fastens the two semi-circular first ring body 101 and second ring body 102 to form a large ring around the steel column 2, and the welding slag falls into the ring 1.

[0038] The guide ring plate 4 moves up and down along the steel column 2 to find a fixed position;

[0039] After the fire hose 7 is installed in the placement groove 6, the water inlet connector 701 is connected to the water pump. The water pump pumps water, and the fire hose 7 rapidly expands in the placement groove 6, forming radial pressure between itself and the limiting ring plate 5 and the guide ring plate 4, which is applied to the steel column 2 and increases the friction between the guide ring plate 4 and the steel column 2. The first stop valve 702 at the other end of the fire hose 7 is closed to prevent water from flowing out. When disassembly is required, the water pump is turned off and the first stop valve 702 is opened to drain the water. The fire hose 7 not only serves to fasten the hose but also cools the welding slag to ensure welding safety.

[0040] In this embodiment, a second water stop valve 702 is also installed on the fire hose 7 behind the water inlet connector 701.

[0041] Once the fire hose 7 has expanded and tightened, the second stop valve 702 can be closed, and the water pump can be turned off to maintain the tightened state.

[0042] In this embodiment, a rib plate 8 is also provided between the support ring 1 and the guide ring plate 4.

[0043] This structure prevents the fire hose 7 from being pressed tightly against the support ring 1 and the guide ring plate 4, thus reducing the space for receiving slag.

[0044] This embodiment utilizes water pressure to secure the fire-receiving plate to the steel column, which facilitates the collection of welding slag during the welding process of the upper and lower steel columns, provides wind protection, prevents air bubbles from forming in the weld due to wind, and is easy to remove after drainage, making it very convenient.

[0045] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several equivalent substitutions or obvious modifications can be made without departing from the concept of the present invention, and all such modifications, with identical performance or use, should be considered within the protection scope of the present invention.
