[0018] The technical solution provided by the utility model has the following advantages:

[0019] 1. This embodiment provides an H-shaped column web fire hopper, comprising: a fire baffle and a fixing structure. Two fire baffles are provided, fixedly supported by the fixing structure and arranged relative to each other within the web groove on either side of the H-shaped column. The fire baffle includes a receiving portion, which is inserted into the web groove. The inner side of the receiving portion abuts the surface of the H-shaped column web. The side of the receiving portion closest to the area to be welded serves as a receiving surface, and the plane on which the receiving surface lies intersects with the plane on which the web surface of the H-shaped column lies. Before welding, the fire baffle is fixedly inserted below the welding position by the fixing structure. The upper surface of the receiving portion serves as the receiving surface. The receiving surface serves to receive waste and sparks generated during welding, thereby avoiding the problem of sparks falling when welding the H-shaped steel column web due to the inability to use a welding tool platform due to the small cross-section, thereby improving safety.

[0020] 2. The fire baffle provided by the present invention is L-shaped. The horizontal portion of the fire baffle is a receiving portion, and the top surface of the receiving portion is a receiving surface. The receiving portion is arranged perpendicular to the web of the H-shaped column. The plane where the receiving surface is located is perpendicular to the plane where the plate surface of the web of the H-shaped column is located, so as to ensure that sparks or welding slag waste can fall on the receiving surface. The vertical portion of the fire baffle is the fire baffle, which is fixed to the outside of the receiving portion, that is, the side away from the web of the H-shaped column. The fire baffle and the receiving portion can be arranged as one piece. The fire baffle is bent upward from the receiving portion. The inner side of the fire baffle close to the web of the H-shaped column is the fire baffle surface. The plane where the fire baffle surface is located is parallel to the plane where the plate surface of the web of the H-shaped column is located. The width of the fire baffle is the same as the width of the web of the H-shaped column, so as to ensure that the fire baffle can fit the inner wall of the web groove of the H-shaped column and prevent sparks from leaking from the gap between the fire baffle and the inner wall of the web groove. The fire stop surface blocks flying sparks and, together with the receiving surface, forms a fire contact area within which the welding position is located. During welding, flying sparks are blocked by the fire stop surface and fall onto the receiving surface, further preventing them from falling and improving safety. The L-shaped fire stop plate, inserted into the H-beam, avoids sparks from falling when welding the H-beam web due to the small cross-section and inability to use the welding tool platform.

[0021] 3. The fixing structure provided by the present invention includes a fixing part, a fastening wire, and a supporting part. The fixing part is a flat quadrangular prism, and there are two fixing parts. The length of the fixing part is greater than the width between the two side surfaces of the H-shaped column. The fastening wire is an iron wire. The supporting part is a clamp. During installation, the middle parts of the two fixing parts are horizontally welded to the outside of the corresponding fire baffle, and the two sides of the fixing parts extend a certain distance from the flange of the H-shaped column. The fastening wire is wrapped around the protruding section on the same side of the two fire baffles, and is wrapped counterclockwise or clockwise around the outside of the protruding section. The entire fastening wire is annular. The flat iron is bundled into an integral structure through the iron wire and the H-shaped column, pressing the two fixing parts tightly against the H-shaped column. At the same time, four supporting parts are provided below the fire baffle.

[0033] Example 1

[0034] This embodiment provides an H-shaped column web fire bucket, such as Figure 1 and Figure 2As shown, it includes: a fire baffle 2 and a fixing structure 3. Two fire baffles 2 are provided, and the two fire baffles 2 are fixedly supported by the fixing structure 3 and arranged relative to each other in the web groove on both sides of the H-shaped column 1. The fire baffle 2 includes a receiving portion 21, which is inserted into the web groove. The inner side of the receiving portion 21 abuts the surface of the web of the H-shaped column 1. The side of the receiving portion 21 closest to the area to be welded is the receiving surface, and the plane of the receiving surface intersects with the plane of the plate surface of the web of the H-shaped column 1. Before welding, the fire baffle 2 is fixed and inserted below the welding position by the fixing structure 3. The upper surface of the receiving portion 21 serves as the receiving surface. The receiving surface is used to receive waste and sparks generated during the welding process, thereby avoiding the problem of sparks falling when welding the web of the H-shaped steel column due to the small cross-section and the inability to use the welding tool platform, thereby improving safety.

[0035] Specifically, the fire baffle 2 is L-shaped, such as Figure 1 and Figure 2 As shown, the horizontal part of the fire baffle 2 is the receiving portion 21, the top surface of the receiving portion 21 is the receiving surface, the receiving portion 21 is arranged perpendicular to the web of the H-shaped column 1, and the plane where the receiving surface is located is perpendicular to the plane where the plate surface of the web of the H-shaped column 1 is located, so as to ensure that sparks or welding slag waste can fall on the receiving surface. The vertical portion of the fire baffle 2 is a fire stop 22, which is fixed to the outside of the receiving portion 21, that is, on the side away from the web of the H-shaped column 1. The fire stop 22 and the receiving portion 21 can be integrally arranged. The fire stop 22 bends upward from the receiving portion 21. The inner side of the fire stop 22, near the web of the H-shaped column 1, is a fire stop surface. The plane on which the fire stop surface is located is parallel to the plane on which the plate surface of the web of the H-shaped column 1 is located. The width of the fire baffle 2 is the same as the width of the web of the H-shaped column 1, ensuring that the fire baffle 2 can fit the inner wall of the web of the H-shaped column 1 and preventing sparks from escaping through the gap between the fire baffle 2 and the inner wall of the web. The fire stop surface can block flying sparks. The fire stop surface and the receiving surface enclose a fire contact area, and the welding position is located within this fire contact area. When welding, flying sparks are blocked by the fire stop surface and fall onto the receiving surface, further preventing sparks from falling and improving safety. The L-shaped fire baffle 2 is inserted into the H-shaped column 1, which avoids the problem of sparks falling when the web of the H-shaped column 1 is welded because the welding tool platform cannot be used due to the small cross-section.

[0036] Furthermore, the thickness of the fire baffle 2 is greater than or equal to 1.2 mm; both the receiving surface and the fire baffle surface are paved with a fireproof layer, the material of the fireproof layer is fireproof cotton, which prevents the fire baffle 2 from being damaged or even penetrated by high-temperature sparks or welding slag waste, which affects subsequent fire connection.

[0037] In this embodiment, if Figure 1 and Figure 2As shown, the fixing structure 3 includes a fixing member 31, a fastening wire 32, and a support member 33. The fixing member 31 is a flat quadrangular prism. Two fixing members 31 are provided, and their length is greater than the width between the two side faces of the H-shaped column 1. The fastening wire 32 is an iron wire, and the support member 33 is a clamp. During installation, the middle portions of the two fixing members 31 are horizontally welded to the outside of the corresponding fire stop 22, one for each side. The two sides of the fixing members 31 extend a distance beyond the flange of the H-shaped column 1. The fastening wire 32 is wrapped around the protruding sections on the same side of the two fire stop panels 2, either counterclockwise or clockwise around the outside of the protruding sections. The entire fastening wire 32 forms a ring. The flat iron is bound to the H-shaped column 1 via the iron wire to form a single structure, pressing the two fixing members 31 tightly against the H-shaped column 1. At the same time, four support members 33 are set below the fire baffle 2. The four support members 33 are correspondingly clamped below the fire baffle 2 to support the fire baffle 2, further preventing the fire baffle 2 from falling. The fire baffle 2 is supported and fixed by fastening wires 32 and support members 33, reducing damage to the surface anti-corrosion system of the H-shaped column 1.

[0038] The steps for using the H-shaped column web fire hopper provided by the present invention are as follows:

[0039] First, horizontally weld the middle portions of the two fixings 31 to the corresponding sides of the fire stop 22, away from the receiving portion 21. Next, determine the desired welding location and clamp the four support members 33 to the flanges near the welding location, ensuring that the four support members 33 are aligned horizontally. Insert the receiving portion 21, facing the web, into the web grooves on both sides of the H-shaped column 1 and place it above the support members 33. Then, wrap the fastening wire 32 around the protruding sections on the same side of the two fire stop panels 2 to form a single unit. The welding location is within the fire contact area, and installation is complete.

[0040] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
