DETAILED DESCRIPTION

[0023] The technical solutions of the present application are further described below, but the scope of protection is not limited to the description.

[0024] As Figs. 1 to 4 shown.

[0025] The fixed pulling system of the arc-shaped member of the steel building body of the present application comprises:

[0026] The steel structure building body 9 is fixed on the ground foundation, and the side of the steel structure building body 9 has vertically and spaced arc-shaped steel beam members 1.

[0027] The inner diameter surface of the arc-shaped steel beam member 1 below is fixedly connected with the steel structure building body 9 through a pull rod 11; one end of the pull rod 11 is fixedly connected with the steel structure building body 9 through spot welding; the other end of the pull rod 11 is provided with a bayonet 12 to be clamped with the vertical reinforcing plate 13 of the arc-shaped steel beam member 1 below, and the vertical reinforcing plate 13 is a component fixedly provided with the arc-shaped steel beam member 1 itself; the pull rod 11 is two spaced pull rods for pulling and connecting the arc-shaped steel beam member 1 below on the steel structure building body 9 for limiting.

[0028] The upper and lower surfaces of the two ends of the arc-shaped steel beam member 1 below are fixedly connected with the side of the steel structure building body 9 through spot welding plates 14.

[0029] The arc-shaped steel beam member 1 below is supported on the bottom surface platform 3 through a bottom support rod 2 corresponding to the clamping position of the pull rod 11 and the steel structure building body 9, and the arc-shaped steel beam member 1 below and the bottom support rod 2 are fixedly connected through bolts.

[0030] The arc-shaped steel beam member 1 above is supported above the arc-shaped steel beam member 1 below through an upper support rod 4, and the two ends of the arc-shaped steel beam member 1 above are fixedly connected with the side of the steel structure building body 9 through a welding layer 5.

[0031] A clamping stable material receiving hopper 6 is installed on the arc-shaped steel beam member 1 at the welding layer 5.

[0032] The two ends of the arc-shaped steel beam member 1 below are fixedly connected with the side of the steel structure building body 9 through spot welding plates 14, and are pulled and connected through the pull rod 11 and supported through the bottom support rod 2, so that the arc-shaped steel beam member 1 below forms a force whole to support the arc-shaped steel beam member 1 above through the upper support rod 4. After the arc-shaped steel beam member 1 above is fixedly connected with the steel structure building body 9 through the welding layer 5, the arc-shaped steel beam member 1 below and the steel structure building body 9 are welded, thereby solving the problem that the arc-shaped steel beam member 1 below needs to be disassembled after the upper arc-shaped steel beam member is supported by the scaffold erected from the ground, and improving the construction efficiency. After the arc-shaped steel beam member 1 below is welded, the upper support rod 4, the bottom support rod 2 and the pull rod 11 are disassembled. The upper support rod 4 is fixedly connected with the arc-shaped steel beam member 1 above and below through bolts and nuts, and the bottom support rod 2 is fixedly connected with the arc-shaped steel beam member 1 below through bolts and nuts.

[0033] The steel building body arc member connection construction method comprises the following steps:

[0034] The arc-shaped steel beam member 1 below is a force whole to support the arc-shaped steel beam member 1 above, thereby presenting the construction process of the fixed pulling and connecting system of the steel building body arc member.

[0035] The steel structure building body needs to be welded by multiple components, and when the arc-shaped steel beam component is welded on the side of the steel structure building body, the welding slag generated by welding will fall with high temperature, which will affect the installation of the personnel below the construction environment, so a slag collector is needed to catch the welding slag.

[0036] The existing slag collector for catching the welding slag is disclosed in Chinese Patent No. CN208961281U. Although the material receiving hopper can be hung by a rope and a hook, in a coastal and high-altitude environment, the wind is relatively strong, which can easily cause the material receiving hopper to swing on the hook with the rope and throw out the welding slag.

[0037] The slag collector for welding according to the present application comprises:

[0038] A material receiving hopper 6 is installed on the arc-shaped steel beam component 1 below the welding layer 5 to catch the welding slag. The material receiving hopper 6 is stably installed on the arc-shaped steel beam component 1 by being clamped by two groups of installation assemblies 7.

[0039] The installation assembly 7 comprises an installation rod 72 with a horizontal section of an elastic holding cylinder 71. The elastic holding cylinder 71 is made of elastic rubber material. The installation rod 72 with the horizontal section on both sides of the elastic holding cylinder 71 is screwed with extrusion nuts 75. The two extrusion nuts 75 are screwed on the horizontal section of the installation rod 72 to oppositely approach and extrude the elastic holding cylinder 71, so that the elastic holding cylinder 71 is elastically deformed.

[0040] The vertical sections of the installation rod 72 at both ends are screwed with clamping plates 74 through nuts A73. The clamping plates 74 are provided with through holes for the vertical sections of the installation rod 72 to slidably penetrate. The nuts A73 are screwed against the clamping plates 74 and tightly against the arc-shaped steel beam component 1. The upward extrusion force of the clamping plates 74 against the arc-shaped steel beam component 1 and the downward extrusion force of the elastic holding cylinder 71 elastically deformed downward against the arc-shaped steel beam component 1 are clamped on the arc-shaped steel beam component 1.

[0041] The bottom end of the installation rod 72 penetrates through the through hole provided on the side of the material receiving hopper 6. The bottom end of the installation rod 72 is clamped to the side of the material receiving hopper 6 through two clamping nuts 76, so that the bottom end of the installation rod 72 and the side of the material receiving hopper 6 are detachably fixed.

[0042] The material receiving hopper 6 is clamped and connected with the installation assembly 7. The installation assembly 7 is clamped and stably installed on the arc-shaped steel beam component 1 through the clamping plates 74 and the elastic holding cylinder 71. When it is blown by strong wind, the elastic force of the elastic holding cylinder 71 provides a buffer. The clamping plates 74 and the elastic holding cylinder 71 clampingly install the material receiving hopper 6 on the arc-shaped steel beam component 1 to keep it stable and avoid swinging. The problem that the material receiving hopper hung by the rope and the hook easily swings and throws out the welding slag in strong wind is solved.
