Description

Technical Field

[0001] This utility model relates to the field of building welding tools, and more specifically to a detachable windproof fire-resistant device suitable for circular steel pipe columns. Background Technology

[0002] Steel structures, as a lightweight, high-strength, and quick-to-construct material, are widely used in super high-rise buildings. However, with the increasing prevalence of steel structure engineering, quality control and safety assurance during construction have become increasingly prominent issues, attracting industry attention. Among various steel structure systems, circular steel pipe columns are widely used in the core support structures of super high-rise public buildings due to their unique mechanical properties and aesthetics. However, welding operations on circular steel pipe columns face a series of challenges. Traditional welding hoppers are mostly square, making it difficult to fit tightly against the circular steel pipe columns, causing sparks and welding slag to easily splash into the surrounding environment, increasing the risk of fire. Simultaneously, implementing wind protection measures is also difficult. Conventional windbreaks are not only cumbersome and costly to erect, but also difficult to effectively exhaust welding fumes in limited spaces, affecting the health of construction workers and welding quality.

[0003] To address the aforementioned issues, providing a windproof fire-connection device that can meet the welding requirements of circular steel pipe columns while effectively solving problems such as poor fire connection and inadequate wind protection is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0036] In the description of this utility model, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] Because traditional welding hoppers are mostly square in design, they are difficult to fit tightly against round steel pipe columns, causing sparks and welding slag to easily splash into the surrounding environment, increasing the risk of fire. At the same time, implementing windproof measures also faces difficulties. Conventional windproof sheds are not only cumbersome and costly to erect, but also difficult to effectively remove welding fumes in a limited space, affecting the health of construction workers and the quality of welding.

[0038] In view of this, the present invention provides a detachable windproof fire-fighting device suitable for circular steel pipe columns, see appendix. Figure 1 It is installed near the weld seam of the steel pipe column G to be welded, and includes:

[0039] The clamp base support 10 clamps the steel pipe column G tightly;

[0040] The fire collection bucket 20 is installed on the base support 10 of the clamp and surrounds the steel pipe column G to collect welding slag and sparks that fall off during welding.

[0041] The spliced ​​side plate 30 is movably connected to the fire-receiving hopper 20 to form a windproof structure during the welding process.

[0042] The above solution uses a clamp base 10 to hold the steel pipe column G tightly, and then a fire collection bucket 20 is installed on the top of the clamp base 10 to collect the welding slag and sparks that fall off the steel pipe column G around the welding. A splicing side plate 30 is movably connected to the top of the fire collection bucket 20 to prevent wind during welding, reduce the adverse effects of weather on welding operations, improve welding quality, and reduce light pollution to the surrounding area.

[0043] In the embodiments of this utility model, see the appendix. Figure 2 and 3 The clamp base 10 includes two semi-circular clamps 101, each with a connecting portion 103. Each connecting portion 103 can be a connecting ear with a connecting hole. The two clamps 101 are connected to the steel pipe column G using screws, providing a fixed foundation. Multiple connecting holes can be provided; in this embodiment, each connecting ear has two connecting holes, and each clamp 101 has two connecting ears.

[0044] The clamp 101 can be designed with a semi-circular steel plate, which can be made of 5mm thick steel plate, and the height can be 200-300mm.

[0045] Advantageously, in a specific embodiment of the present invention, each of the clamps 101 is provided with two or more legs 102 on its outer wall. The legs 102 are evenly distributed on the outer wall of the clamps 101 to form a support for connecting the fire bucket and splicing the side plate 30.

[0046] In the embodiments of this utility model, see the appendix. Figure 4-6 The fire-receiving bucket 20 includes:

[0047] The first bucket body 201 is fixed to the clamp base 10;

[0048] The second bucket body 202 and the third bucket body 203 are rotatably connected to both sides of the first bucket body 201. The ends of the second bucket body 202 and the third bucket body 203 away from the first bucket body 201 have fixing parts 206. The fixing parts 206 can be pin sleeves, connected by inserting a pin shaft. An angle hinge 204 can be provided at the rotatable connection between the second bucket body 202, the third bucket body 203 and the first bucket body 201.

[0049] Multiple plug-in parts 205 are fixed to the top of the first bucket body 201, the second bucket body 202 and the third bucket body 203, and can connect to the splicing side plate 30. The plug-in parts 205 can be uprights, which are made of steel bars with a diameter of 12mm.

[0050] Specifically, the first bucket 201, the second bucket 202, and the third bucket 203 can be enclosed to form a circle with an inner diameter of D, and an outer regular hexagon concentric with the circle. Each bucket includes a bottom plate and a side plate. The bottom plate surrounds the steel pipe column G, and the top of the side plate is connected to the insertion part 205. The diameter of the inscribed circle of the regular hexagon is D + (100~300) mm.

[0051] The base plate can be made of 2.5-3mm steel plate, with a circular hollow part on the inner edge and a diameter of D (the diameter of the circular steel pipe column). The outer edge is a regular hexagonal design concentric with the circle, and the diameter of its inscribed circle can be (D+200) mm. The side plates are made of 0.4-0.6mm steel plate and can be 200mm high. The base plate and side plates are welded and fixed.

[0052] During installation, open the second bucket 202 and the third bucket 203, fit the fire-receiving bucket into the circular steel pipe column and place it on the clamp base, close the second bucket 202 and the third bucket 203 and fix it with a pin.

[0053] The splicing side panel 30 used in the above embodiments is shown in the appendix. Figure 7-9 ,include:

[0054] The three side panel bodies 301 are all independent, unfoldable panels. Each panel has a sleeve 302 at its unfolded center that rotatably engages with the insertion part 205. Each panel also has pin sleeves 303 on both sides, fixed to pins, with the corresponding pin sleeves 303 on adjacent panels staggered. The three side panel bodies 301 are located on a regular hexagonal side panel, forming a regular hexagon and a windproof structure. Welding can be performed by opening the pin connections of any two side panel bodies 301 as needed. Each panel rotates around the upright inserted at the sleeve 302. One possible implementation is that the sleeve 302 is connected in a manner similar to the corner hinge 204, except that an upright needs to be inserted into the center of the sleeve 302.

[0055] Specifically, the splicing side panel can be constructed as a hexagonal cylindrical structure consisting of three sets of hinges. Each set of hinges comprises two rectangular steel plates connected by detachable pins. The rectangular steel plates can be 0.5mm thick, 500mm high, and have the same side length as the base plate. Each end of the hinge has two inserts 302, which can be made of 1mm thick steel plate with an inner diameter of 13mm, and can be directly inserted into the upright of the lower fire-receiving hopper. In windy weather, the splicing side panel can be used for wind protection, forming a welding protective cover. During welding operations, the hinges on the side to be welded are opened for welding, effectively ensuring welding quality while reducing light pollution to the surrounding area.

[0056] This utility model is applicable to welding operations of large-diameter circular steel pipe columns (diameter of 600mm~1200mm) in steel structure engineering construction where welding operations are possible.
