Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction equipment, and in particular relates to a welding device for steel trusses. Background Art
[0002] During the construction of a steel structure plant with a steel truss structure, after the truss is hoisted to high altitude, two trusses need to be connected. Conventional connection structures include high-strength bolts and welding. During high-altitude welding, sparks generated by welding will scatter and fall, which may cause harm to personnel and materials below; therefore, a general welding operation will set a fire connection device under the welding point to prevent sparks from scattering. For steel trusses, after the upper and lower chord connecting rods are installed, the conventional fire connection bucket cannot be installed due to the influence of the connecting rods, resulting in many truss welding operations often not being equipped with a fire connection device, which poses a great safety hazard. Therefore, a fire connection device for steel truss welding is used to solve this problem. Utility Model Content
[0003] To achieve the above-mentioned purpose, the utility model provides a fire connection device for steel truss welding, including a horizontally arranged support rod, a fire bucket is horizontally arranged below the support rod, both ends of the support rod are connected to the two sides of the fire bucket through a connecting rod, two limit plates are slidingly sleeved on both ends of the support rod, a plurality of screws are horizontally arranged between the two limit plates, both ends of the screw slide through the limit plates on both sides respectively, and both ends of the screw are threadedly sleeved with limit rings.
[0004] Furthermore, the upper end of the connecting rod is vertically inserted into the supporting rod and fixed by a bayonet, and the lower end of the connecting rod is fixedly sleeved with a connecting ring, and the connecting rod is connected to the fire bucket through the connecting ring.
[0005] Furthermore, the connecting rod is configured as a telescopic rod.
[0006] Furthermore, the number of the screws is set to at least two; when the number of the screws is an odd number, the screws are arranged around the central circumference of the limiting plate; when the number of the screws is an even number, the screws are symmetrically arranged around the center of the limiting plate.
[0007] Furthermore, the optimal number of the screws is four.
[0008] The advantages of the utility model are as follows: the utility model provides a fire connection device for steel truss welding, which not only enables the fire bucket to stably receive welding slag and sparks, preventing sparks from scattering and falling to cause harm to personnel and materials below, but also improves safety protection and reduces potential safety hazards. At the same time, it also solves the problem that after the upper and lower chord connecting rods of the truss are installed, the conventional fire connection bucket cannot be installed due to the influence of the connecting rods, resulting in many truss welding operations often not being equipped with fire connection devices, thereby further improving safety protection and avoiding potential safety hazards.

[0019] Example 1
[0020] This embodiment provides Figure 1 to Figure 4 The fire connection device for steel truss welding shown in the figure comprises a horizontally arranged support rod 1, a fire bucket 2 is horizontally arranged below the support rod 1, two ends of the support rod 1 are connected to the two sides of the fire bucket 2 through a connecting rod 3, the upper end of the connecting rod 3 is vertically inserted into the support rod 1 and fixed by a bayonet 7, a connecting ring 8 is fixedly sleeved at the lower end of the connecting rod 3, and the connecting rod 3 is connected to the fire bucket 2 through the connecting ring 8, two limit plates 4 are slidingly sleeved on both ends of the support rod 1, a plurality of screws 5 are horizontally arranged between the two limit plates 4, and the number of the screws 5 is set to at least two; when the number of the plurality of screws 5 is an odd number, the plurality of screws 5 are arranged around the central circumference of the limit plate 4; when the number of the plurality of screws 5 is an even number, the plurality of screws 5 are symmetrically arranged around the center of the limit plate 4, and the two ends of the screw 5 slide through the limit plates 4 on both sides respectively, and both ends of the screw 5 are threadedly sleeved with limit rings 6.
[0021] When in use, first place the support rod 1 horizontally on the truss below the welding point, then install two limit plates 4 on the support rod 1 to clamp the truss, and through the cooperation with the screw rod 5 and the limit ring 6, the support rod 1 is tightly fixed on the truss, wherein the number of screw rods 5 is optimally four, and the two adjacent screw rods 5 are located below the truss, so as to further strengthen the limiting and fixing effect of the support rod 1 and the truss, so that the fire bucket 2 fixedly connected by the connecting rod 3 can be firmly fixed below the welding point, so that the fire bucket 2 can stably receive the welding slag and sparks to prevent the sparks from scattering and falling, and the fire bucket 2 can stably receive the welding slag and sparks below. At the same time, by means of the arranged screw rod 5, when the fire connection device is installed, if there are upper and lower chord connecting rods below the welding point, the fire connection device can be directly installed on its connecting rod, and then the position of the screw rod 5 on the limiting plate 4 is adjusted by rotating the limiting plate 4, so that the connecting rod is inserted diagonally between the four screw rods 5, thereby not only increasing the stability of the fixing on the connecting rod, but also making the fire connection device installed on the connecting rod, the fire connection bucket 2 remains in a horizontal state to receive sparks and welding slag.
