Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary tools, and more specifically, to a protective device for welding fumes of steel beams. Background Technology

[0002] The support structure of the process plant needs to be fixed to the steel beams of the civil engineering structure. During the welding construction of the support structure, welding fumes are generally collected by a welding fume collection device. However, in actual construction, because a small amount of welding fumes is not collected at the welding point, the welding fumes cannot be avoided from affecting the steel beams. This can easily contaminate the civil engineering steel beams, causing contamination of the fireproof coating and posing a certain risk to the protection of finished products.

[0003] To protect the finished steel beams, the conventional practice is to wrap the welding area with protective fabric, clips, etc., to prevent welding fumes from contaminating the beams. However, existing protective methods cannot guarantee a complete fit with the steel beams. Furthermore, the low density of welding fumes allows them to easily seep through gaps to the surface of non-welded areas, causing contamination and inadequate protection. This necessitates additional manual processing later, increasing project costs. Utility Model Content

[0033] Figure 1 This is a schematic diagram of the cooperation structure between the steel beam welding fume protection device 10 and the steel beam 20 provided in this embodiment. Figure 2 This is a structural schematic diagram of the steel beam welding fume protection device 10 provided in this embodiment from a first-view perspective. Figure 3 This is a structural schematic diagram of the steel beam welding fume protection device 10 provided in this embodiment from a second perspective, specifically a bottom-view perspective. Please refer to the reference diagram. Figures 1-3This embodiment provides a steel beam welding fume protection device 10, hereinafter referred to as the protection device 10, which includes a protective body 100 for installation and fixation on a steel beam 20. The protective body 100 has a protective plate 131 for adhering to the wall surface where the welding position of the steel beam 20 is located. The protective plate 131 is provided with welding holes 132, through which the welding position is exposed to ensure welding can proceed. The protective plate 131 is used to shield the steel beam 20 portion around the welding position, and the protective plate 131 is provided with a sealing member 133. The sealing plate is arranged around the welding holes 132. Thus, when the protective plate 131 is adhering to the wall surface of the steel beam 20, the sealing member 133 closes any gaps that may exist between the protective plate 131 and the wall surface, ensuring a good fit with the wall surface, thereby preventing fine fumes from entering between the protective plate 131 and the wall surface of the steel beam 20, achieving effective protection for the steel beam 20, and effectively improving the situation of steel beam 20 contamination during welding.

[0034] The protective device 10 provided in this embodiment will be further described below:

[0035] Please continue to refer to the reference. Figures 1-3 In this embodiment, the protective body 100 also includes a connecting structure 120 installed on both sides of the protective plate 131. The connecting structure 120 includes a connecting plate 121 and a connecting part 122. The two ends of the connecting part 122 are respectively connected to the connecting plate 121 and the protective plate 131. The protective plate 131 and the connecting plate 121 are arranged at intervals relative to each other, thereby forming a clamping space 136 for clamping the steel beam 20 between the protective plate 131 and the connecting plate 121.

[0036] Specifically, in this embodiment, the steel beam 20 to be welded is an I-beam, which has a web 21 and a flange 22 fixed to one end of the web 21. The connection between the flange 22 and the web 21 is located in the middle of the flange 22, thus forming a T-shaped structure. The part of the flange 22 on one side of the web 21 is the first part 23, and the part of the flange 22 on the other side of the web 21 is the second part 24. The welding position is located on the side wall of the flange 22 away from the web 21. During installation, the first part 23 is clamped in the clamping space 136 formed by the connecting structure 120 on one side of the protective plate 131, and the second part 24 is clamped in the clamping space 136 formed by the connecting structure 120 on the other side of the protective plate 131, thus achieving a fixed connection between the protective body 100 and the steel beam 20.

[0037] It should be noted that the connection structure 120 between the protective body 100 and the steel beam 20 is not limited here. It is understood that in some other embodiments, other structures can also be used to achieve the connection. For example, upright plates are set on both sides of the protective plate 131, and the steel beam 20 is clamped by the upright plates on both sides to achieve the connection and fixation with the steel beam 20. At this time, the steel beam 20 can be other structural forms, such as square steel.

[0038] Furthermore, the protective body 100 also includes a clamping bolt 134. The connecting plate 121 has a mounting through hole 123, and the clamping bolt 134 is screwed into the mounting through hole 123. Simultaneously, the end of the clamping bolt 134 protrudes from the connecting plate 121 and is located within the clamping space 136. Therefore, by tightening the clamping bolt 134, the steel beam 20 can be pressed tightly against the protective plate 131. This ensures connection reliability and also compresses the sealing member 133, guaranteeing a good fit between the protective plate 131 and the steel beam 20. Optionally, the sealing member 133 is a fireproof cloth pasted and fixed onto the protective plate 131. It is understood that in some other embodiments, other materials may be used as the sealing member 133, such as materials that are heat-resistant and have a certain degree of compressibility.

[0039] Figure 4 This is a structural schematic diagram of the protective component 110 provided in this embodiment. Figure 5 This is a structural schematic diagram of the protective component 110 provided in this embodiment from another perspective. Please refer to the reference. Figures 1-5 In this embodiment, the protective body 100 includes at least two protective members 110, which are respectively installed on both sides of the steel beam 20. Each protective member 110 has a protective portion 113, and the protective portions 113 of the at least two protective members 110 are spliced ​​together to form a protective plate 131, thus the sealing member 133 is disposed on the protective portion 113. At the same time, a notch 114 is provided on the protective portion 113, and when the at least two protective members 110 are spliced ​​together, the notch 114 is spliced ​​together to form a welding hole 132.

[0040] Specifically, in this embodiment, at least two protective members 110 include a first protective member 111 and a second protective member 112 installed opposite to each other on both sides of the steel beam 20. Correspondingly, the protective portion 113 on the first protective member 111 is the first protective portion, and the protective portion 113 on the second protective member 112 is the second protective portion. A connecting structure 120 on one side of the protective body 100 is fixedly connected to the first protective portion, and the connecting plate 121 of the connecting structure 120 is spaced apart from the first protective portion to form a clamping space 136 for clamping the first part 23. Correspondingly, a connecting structure 120 on the other side of the protective body 100 is fixedly connected to the second protective portion, and the connecting plate 121 of the connecting structure 120 is spaced apart from the second protective portion to form a clamping space 136 for clamping the second part 24.

[0041] The protective portion 113 has a first end and a second end opposite to each other. The connecting portion 122 is fixedly connected to the first end, thereby defining the position of the clamping space 136 at the first end by the connecting portion 122. Correspondingly, the clamping space 136 forms an opening at the second end, so that the wing plate 22 can enter and exit the clamping space 136 through the opening. In this embodiment, the protective portion 113 has a first dimension in the direction from the first end to the second end, and the connecting plate 121 has a second dimension in the direction from the first end to the second end. The first dimension is larger than the second dimension, so that when the second ends of the first protective portion and the second protective portion abut against each other, a gap is formed between the two connecting plates 121 to accommodate the web plate 21.

[0042] Optionally, the protective component 110 is an integral structure, that is, the protective part 113, the connecting part 122, and the connecting plate 121 are integrally formed into a fixed connection. It should be noted that, in this embodiment, since the protective body 100 is formed by splicing at least two protective components 110, the fixed connection between the connecting part 122, the connecting plate 121, and the protective part 113 can also ensure the smooth installation of the protective body 100 on the steel beam 20. It is understood that in some other embodiments, the connection relationship between the connecting part 122, the connecting plate 121, and the protective part 113 can also be set according to needs. For example, the connecting part 122 can be rotatably connected to the protective part 113, or the connecting plate 121 can be rotatably connected to the connecting part 122. In this way, the assembly and disassembly of the protective body 100 and the steel beam 20 can be achieved by rotation.

[0043] Furthermore, the protective device 10 also includes an adjusting plate 140, the two ends of which are respectively used to connect the protective members 110 located on both sides of the steel beam 20, that is, the two ends of the adjusting plate 140 are fixedly connected to the first protective member 111 and the second protective member 112 respectively. By setting the adjusting plate 140, the first protective member 111 and the second protective member 112 located on both sides of the steel beam 20 can be connected together.

[0044] Optionally, both ends of the adjusting plate 140 are detachably connected to the first protective member 111 and the second protective member 112 by fastening bolts 135, respectively. Specifically, the protective part 113 is provided with a first connecting hole 115, and both ends of the adjusting plate 140 are provided with second connecting holes 141. The fastening bolts 135 pass through the second connecting holes 141 and are screwed into the first connecting holes 115, thereby realizing the fixed connection between the protective part 113 and the adjusting plate 140.

[0045] Furthermore, the second connecting hole 141 is an oblong hole. Specifically, the first connecting hole 115 is a round hole, and the oblong shape of the second connecting hole 141 extends along both ends of the adjusting plate 140. Thus, when adapting to steel beams 20 of different sizes, and the distance between the first connecting hole 115 of the first protective part and the first connecting hole 115 of the second protective part changes, the adjusting plate 140 can still ensure the connection between the first protective member 111 and the second protective member 112. When the protective structure is adapted to a large-sized steel beam 20, if a gap appears between the first protective part and the second protective part, on the one hand, the gap is small, so even if dust enters the gap, the contact area with the steel beam 20 is small, thus causing less impact; on the other hand, a flexible shielding layer can be provided on the adjusting plate 140. When the adjusting plate 140 is fastened to the first and second protective parts, the flexible shielding layer is embedded in the gap to protect it.

[0046] Optionally, the adjusting plate 140 is made of carbon steel plate.

[0047] In this embodiment, the protective body 100 includes four protective components 110, which are arranged in a rectangular array. Two of the protective components 110 are installed on one side of the steel beam 20, and the other two are installed on the other side of the steel beam 20. The welding hole 132 is formed by splicing the four protective components 110.

[0048] Specifically, in this embodiment, the protective body 100 is formed by splicing four protective components 110, which are two first protective components 111 and two second protective components 112. Since the welding hole 132 is formed by splicing the four protective components 110, the notches 114 on the two first protective components 111 are opened in opposite positions, so that the notches 114 are connected when the two first protective components 111 are spliced. Similarly, the notches 114 on the two second protective components 112 are opened in opposite positions, so that the notches 114 are connected when the two second protective components 112 are spliced. The welding hole 132 formed by splicing is located in the middle of the protective plate 131.

[0049] Optionally, in this embodiment, the notch 114 on the protective member 110 is rectangular, so the welding hole 132 formed by splicing four protective members 110 is rectangular. It is understood that in some other embodiments, the shape of the welding hole 132 can also be set as needed, for example, the welding hole 132 can be set as circular.

[0050] It should be noted that this embodiment does not limit the number of protective components 110 or the structural form of the protective body 100. It is understood that in some other embodiments, the number of protective components 110 can also be set according to the needs, for example, the number of protective components 110 can be set to one, or even the protective body 100 can be set as an integral structure.

[0051] In this embodiment, the portion of the projection of the mounting through hole 123 along the direction from the connecting plate 121 to the protective plate 131 is located at the welding hole 132, and the other portion of the projection is located on the plate body of the protective plate 131. Specifically, as shown... Figure 4 As shown, in the protective member 110, half of the projection of the mounting through hole 123 along the direction from the connecting plate 121 to the protective part 113 is located at the notch 114, and the other projection is located on the plate body of the protective part 113.

[0052] The protective device 10 provided in this embodiment of the present invention is used by first inserting two first protective components 111 from one side of the steel beam 20 into the first part 23, and then inserting two second protective components 112 from the other side of the steel beam 20 into the second part 24, thereby achieving the splicing of four protective components 110. Simultaneously, the welding holes 132 formed after splicing correspond to the welding positions of the steel beam 20. After the four protective components 110 are spliced ​​in place, on the one hand, fastening bolts 135 are installed to connect the two ends of the adjusting plate 140 to the protective components 110 located on both sides of the steel beam 20; on the other hand, clamping bolts 134 are installed to further ensure the fit between the protective plate 131 and the wall surface of the steel beam 20. At this point, the protective device 10 is installed, and welding operations on the steel beam 20 can be performed.

[0053] The protective device 10 exposes the welding position of the steel beam 20 by providing welding holes 132 on the protective body 100. A protective plate 131 surrounds the welding position, and a sealing element 133 is provided around the welding hole 132 on the protective plate 131. This effectively protects the steel beam 20 wall around the welding position, preventing contamination. A clamping bolt 134 is provided to press the steel beam 20 firmly onto the sealing element 133, further enhancing the protective performance. The protective body 100 is formed by splicing at least two protective elements 110, which helps accommodate steel beams 20 of different specifications. It is easy to install, has a simple structure, reduces pre-welding preparation work, lowers the labor intensity of construction workers, improves construction efficiency, and reduces construction costs.

[0054] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
