The utility model discloses a fire receiving bucket for cutting a transition plate on a steel structure, which comprises a fire receiving bucket body 1.
The fire-catching bucket body 1 comprises a transverse fire-catching bucket body 10 and a vertical fire-catching bucket body 12, wherein one end of the transverse fire-catching bucket body 10 is communicated with the lower end of the vertical fire-catching bucket body 12, and the two are integrated. The inner surface of the fire-catching bucket body 1 is provided with a fire-proof layer, and it is not easy to understand that all the inner surfaces of the fire-catching bucket body 1 are provided with fire-proof layers (the fire-proof layers are not shown in the drawing). The vertical receiving hopper body 12 may also be referred to as a vertical receiving hopper body. The lateral receiver body 10 may also be referred to as a horizontal receiver body.
The L-shaped side plate 16 of the fire receiving hopper body 1, which is close to a steel column such as a rectangular steel column 3, is matched with the shape of the steel column vertical surface such as a rectangular steel column vertical surface 2, a plurality of strong magnets 6 are arranged on the inner surface of the L-shaped side plate 16 of the fire receiving hopper body 1, which is close to the steel column vertical surface such as the rectangular steel column vertical surface 2, to absorb the steel column such as the rectangular steel column 3, so that the L-shaped side plate 16, which is close to the steel column such as the rectangular steel column 3, is detachably fixed with the steel column such as the rectangular steel column 3, the transverse fire receiving hopper body 10 is positioned below the cut transition plate 4, and the vertical fire receiving hopper body 12 is positioned in front of flame spraying of the cutting gun. Or (b)
The L-shaped side plate 16 of the upper wing plate top surface of the I-shaped steel beam 5, which is close to the steel beam, of the fire receiving hopper body 1 is matched with the horizontal plane shape of the upper wing plate top surface of the I-shaped steel beam 5, a plurality of strong magnets are arranged on the inner surface of the L-shaped side plate 16 of the upper wing plate top surface of the upper wing plate of the I-shaped steel beam 5, which is close to the fire receiving hopper body 1, so that the L-shaped side plate 16 of the upper wing plate, which is close to the I-shaped steel beam 5, is detachably fixed with the upper wing plate of the I-shaped steel beam 5, an opening of the fire receiving hopper body 1, such as an opening 20 of the transverse fire receiving hopper body, is close to the cut transition plate 4, and the fire receiving hopper body 1, such as the transverse fire receiving hopper body 10, is positioned in front of flame spraying of a cutting gun.
The cut transition plate 4 is also understood as a transition plate 4 to be cut. The detachable fixing of the L-shaped plate 16 and the steel column vertical surface can be understood as detachable fixing of the fire receiving hopper body 1 and the steel column. The detachable fixation of the L-shaped plate 16 and the upper wing plate of the I-shaped steel beam 5 can be understood as detachable fixation of the fire receiving hopper body 1 and the I-shaped steel beam 5.
A hanging rod 18 extending towards the cutting gun direction and used for hanging on a steel beam such as a rectangular steel beam 17 or a steel bracket 19 fixed on a steel column such as the rectangular steel column 3 can be fixed on the top plate 8 of the vertical fire receiving bucket body 12. Generally applicable to two conditions: firstly, the transition plate 4 on the vertical face of the steel column such as the rectangular steel column vertical face 2 is cut, and the steel cross beam such as the rectangular steel beam 17 or the steel corbel 19 is just arranged at the transition plate, so that double insurance is adsorbed and hung. And secondly, the transition plate 4 is used for cutting the steel cross beam such as the rectangular steel beam 17, and is just close to the steel column vertical face such as the rectangular steel column vertical face 2, so that double insurance is hung and absorbed.

Facades are also referred to as vertical surfaces. The strong magnet 6 is also called as neodymium iron boron strong magnet. It will be appreciated that the strong magnet 6 may be attached to a steel column via iron sheet, plastic or the like. The strong magnet 6 can also adsorb the steel column through the fireproof blanket, asbestos and iron sheet. Of course, the positions of the iron sheet, the plastic plate and other attracting magnets can be directly attached to the inner side of the iron sheet, the plastic plate and other attracting magnets without arranging fireproof carpets, asbestos and the like, so that the strong magnet 6 can be attached to the steel column, the steel beam and other attracting magnets, and the detachable fixing effect is better.
The fire-catching bucket body 1 comprises a first end plate 14, two first side plates 15 and a bottom plate 13 of the transverse fire-catching bucket body 10.

The third end plate 9 of the vertical fire-catching bucket body 12 and the second end plate 11 of the horizontal fire-catching bucket body 10 are an integral plate, namely a vertical rectangular plate. Each L-shaped side plate 16 is a unitary plate made up of a first side plate 15 and a second side plate 7. In other words, a second side plate 7 of the vertical fire-catching-bucket body 12 and a first side plate 15 of the horizontal fire-catching-bucket body 10 are an integral plate, and another second side plate 7 of the vertical fire-catching-bucket body 12 and another first side plate 15 of the horizontal fire-catching-bucket body 10 are an integral plate.
The L-shaped side plate 16 of the fire receiving hopper body 1, which is close to the steel column, is a vertical flat plate which is matched with and clung to the shape of a straight vertical surface of the rectangular steel column 3. Or, the L-shaped side plate 16 of the flame receiving bucket body 1 adjacent to the steel column is a vertical arc plate (not shown in the figure, and the same applies below) which is matched with the arc elevation shape of the outer circumferential surface of the round steel column and is tightly attached.
The two L-shaped side plates 16 of the fire receiving hopper body 1 can be vertical flat plates which are matched with and clung to the vertical face shape of the rectangular steel column 3. Or, the two L-shaped side plates 16 of the fire receiving hopper body 1 can be vertical arc plates which are matched with the arc elevation shape of the outer circumferential surface of the round steel column and are clung to each other. Or, one of the two L-shaped side plates 16 of the fire receiving hopper body 1 is a vertical flat plate which is matched with and clung to the shape of a straight vertical surface of the rectangular steel column 3, and the other one is a vertical arc-shaped plate which is matched with and clung to the shape of an arc-shaped vertical surface of the outer circumferential surface of the round steel column. So that the single fire receiving hopper is widely applicable.
The two hanging rods 18 can be fixed on the top plate 8 of the vertical fire receiving hopper body 12 through bolts and nuts, and a limiting structure (not shown in the figure) can be arranged on the free end of the hanging rod 18 and a hanging steel cross beam such as a rectangular steel beam 17 which is fixed on a steel column such as the rectangular steel column 3. The hanging rod 18 can adopt angle steel, a transverse plate of the angle steel can be in threaded connection with the top plate 8 through bolts and nuts, and a vertical plate of the angle steel can be abutted against the two second side plates 7. Limiting structures such as transverse plates of angle steel and steel cross beams such as top plates 8 of rectangular steel beams 17 can be provided with bolt holes, and bolts with big ends are inserted into the bolt holes of the transverse plates and the steel cross beams such as the top plates of the rectangular steel beams 17 to limit, and of course, the limiting structures can also limit each other by adopting strong magnet attraction. After the structure is adopted, when the transition plate 4 on the steel cross beam such as the rectangular steel beam 17 is cut, spark can be effectively prevented from splashing outwards, and harmony and unity of falling cut objects and slag can be well accepted, and the structure for fixing the fire receiving bucket body and the steel cross beam is simple and reliable. The hanging rod 18 can also play a role in enhancing the strength of the fire-catching bucket body 1.
The fire receiving hopper body 1 can be made of iron sheet, and the joint after stamping forming, such as the hemming, is riveted by rivets, and the rivets can be arranged on side plates, such as the L-shaped side plates 16, so that the bonding degree of the side plates, such as the L-shaped side plates 16, and the steel column vertical surface, such as the rectangular steel column vertical surface 2, is better. The fire receiving hopper body can also be made of plastic plates, thin copper plates, thin steel plates, such as thin copper plates, thin steel plates, and the like with the thickness of 1 millimeter. Iron sheet refers to sheet-pressed wrought iron, commonly referred to as lead iron or tin iron.
The fire-proof layer can be the fire blanket, the fire blanket can compress tightly by the inward turn-up of the funnel of extension body 1, fix the card chucking in the funnel of extension body 1, press the frame to compress tightly the structure such as rivet riveting with the interior bottom surface, certainly, as mentioned above, rivet riveting department is general not on both sides board like L font curb plate 16, makes the laminating degree of curb plate L font curb plate 16 and steel construction like rectangle steel column facade 2 better. The fireproof blanket is also called fireproof cloth, and the fireproof blanket and the fireproof cloth can be used commonly. The fire-resistant layer may also be an asbestos board or the like.
The rectangular steel column 3 is generally a rectangular steel pipe. Rectangular steel beams 17 are also typically rectangular steel tubes.
The steel structure should be understood in a broad sense, for convenience of description, the utility model only exemplifies the example of cutting the transition plate 4 on the steel column such as the rectangular steel column 3, namely the box-shaped steel column or the round steel column vertical surface and the steel cross beam such as the rectangular steel beam 17 and the I-shaped steel beam 5, and it is not easy to understand that if the transition plate is cut on other steel structures such as the steel plate shear wall vertical surface and the steel cross beam fixed on the steel plate shear wall, only the fire receiving hopper is adopted, and the protection scope of the utility model is also fallen within.
The above unnumbered components or structures or numbers are not shown. The drawings are schematic only, where the drawings do not conform to the written description or where the drawings do not conform to each other, the written description will take precedence.
