Description

Technical Field

[0001] The utility model relates to a slag collector for welding, belonging to the technical field of steel structure building construction. Background Art

[0002] Steel structure buildings need to be constructed by welding multiple components. When the curved steel beams are welded on the side of the steel structure building, the welding slag produced by the welding carries high temperature and falls, which will affect the installation of the construction workers below. Therefore, a slag catcher is required to catch the welding slag.

[0003] The existing slag catcher for catching welding slag is shown in Chinese Patent Publication No. CN208961281U. Although the hopper can be suspended by a hanging rope and a hook, the strong wind in the construction environment near the sea and at high altitude easily causes the hopper to swing on the hook with the hanging rope and throw out the welding slag. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a slag collector for welding.

[0005] The utility model is achieved through the following technical solutions.

[0006] The utility model provides a slag collector for welding, comprising:

[0007] When in use, the receiving hopper is installed on the arc-shaped steel beam below the welding layer to receive the welding slag;

[0008] The receiving hopper is connected with a mounting assembly for clamping and stably mounting on the arc-shaped steel beam.

[0009] The installation components are divided into two groups distributed at intervals and connected to the receiving hopper.

[0010] The installation assembly comprises an installation rod with an elastic grip tube sleeved on the horizontal section, and clamping plates are installed on the vertical sections at both ends of the installation rod.

[0011] The elastic grip tube is made of elastic rubber material.

[0012] The horizontal sections of the mounting rod on both sides of the elastic grip tube are screwed with extrusion nuts, and the two extrusion nuts are screwed on the horizontal sections of the mounting rod to squeeze the elastic grip tube in opposite directions, so that the elastic grip tube undergoes elastic deformation.

[0013] The vertical sections at both ends of the mounting rod are screwed with a clamping plate through a nut A. The clamping plate is provided with a through hole for the vertical section of the mounting rod to slide through. The nut A is screwed against the clamping plate and pressed tightly against the arc-shaped steel beam. The upward extrusion force of the clamping plate pressing against the arc-shaped steel beam and the downward extrusion force of the elastic grip tube pressing the arc-shaped steel beam downward due to elastic deformation are clamped on the arc-shaped steel beam.

[0014] The bottom end of the mounting rod passes through a through hole provided on the side of the receiving hopper, and the bottom end of the mounting rod is clamped to the side of the receiving hopper through two clamping nuts.

[0015] The beneficial effects of the present invention are as follows: the material receiving hopper is clamped and connected to the mounting assembly, and the mounting assembly is clamped and stably mounted on the arc-shaped steel beam by means of a clamping plate and an elastic gripping tube. When blown by strong winds, the elastic force of the elastic gripping tube provides a buffer, and the clamping plate and the elastic gripping tube clamp the material receiving hopper and mount it on the arc-shaped steel beam to keep it stable and avoid swinging, thus solving the problem that the material receiving hopper is easily swung and throws out welding slag when it is suspended by a hanging rope and a hook when the wind is strong.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0022] like Figures 1 to 4 shown.

[0023] When welding an outwardly projecting curved steel beam to a steel structure, the curved beam must first be supported at a corresponding height before being welded to the side of the steel structure. Existing steel beam support technology, as described in Chinese Patent Publication No. CN112459488A, allows for ground-based scaffolding to support the beams. However, in construction environments with two vertically spaced curved beams, the scaffolding required to be disassembled after the upper curved beam is completed, as it occupies space below the lower curved beam. This reduces construction efficiency.

[0024] The present application provides a fixing and fastening system for arc-shaped components of a steel building, comprising:

[0025] A steel structure building body 9 is constructed and fixed on a ground foundation, and arc-shaped steel beams 1 are vertically spaced apart on the sides of the steel structure building body 9 .

[0026] The inner diameter surface of the curved steel beam 1 below is fixedly connected to the steel structure building body 9 through a tie rod 11; one end of the tie rod 11 is spot-welded to the steel structure building body 9; the other end of the tie rod 11 is provided with a bayonet 12 which engages with the vertical reinforcement plate 13 on the curved steel beam 1 below, and the vertical reinforcement plate 13 is a component fixed to the curved steel beam 1 itself; the tie rods 11 are two spaced-apart tie rods that tie the curved steel beam 1 below to the steel structure building body 9 for position limiting.

[0027] The upper and lower surfaces of both ends of the arc-shaped steel beam 1 at the bottom are spot-welded and fixedly connected to the side edges of the steel structure building body 9 through spot welding plates 14.

[0028] The arc-shaped steel beam 1 at the bottom is supported on the bottom platform 3 by the bottom support rod 2. The bottom support rod 2 corresponds to the engagement position between the pull rod 11 and the steel structure building body 9. The arc-shaped steel beam 1 at the bottom is fixed to the bottom support rod 2 by bolts.

[0029] The upper arc-shaped steel beam 1 is supported on the lower arc-shaped steel beam 1 by an upper support rod 4 , and both ends of the upper arc-shaped steel beam 1 are fixed to the side of the steel structure building body 9 by a welding layer 5 .

[0030] A clamping and stable receiving hopper 6 is installed on the arc-shaped steel beam 1 at the welding layer 5.

[0031] The two ends of the lower curved steel beam 1 are spot-welded and positioned with the side of the steel structure building body 9 by spot welding plates 14. At the same time, the tension rod 11 is used to pull the force and the bottom support rod 2 to support the curved steel beam 1 below, so that the curved steel beam 1 below forms a force-bearing whole to install the upper support rod 4 to support the curved steel beam 1 above. After the upper curved steel beam 1 is welded and fixed to the steel structure building body 9 by the welding layer 5, the curved steel beam 1 below can be welded to the steel structure building body 9 immediately, solving the problem that the scaffolding supporting the upper curved steel beam from the ground needs to be disassembled before the curved steel beam below can be installed, thereby improving construction efficiency. After the welding of the lower curved steel beam 1 is completed, the upper support rod 4, the bottom support rod 2, and the tension rod 11 are disassembled. When the upper support rod 4 is installed, it is detachably fixed to the upper and lower curved steel beams 1 by bolts and nuts. When the bottom support rod 2 is installed, it is detachably fixed to the lower curved steel beam 1 by bolts and nuts.

[0032] The present application provides a method for connecting arc parts of a steel building, comprising:

[0033] The lower arc-shaped steel beam 1 is used as a load-bearing whole to support the upper arc-shaped steel beam 1, thereby presenting the construction process of the fixed tie system of the circular arc parts of the steel building body.

[0034] A slag collector for welding in the present application comprises:

[0035] A receiving hopper 6 is mounted on the arc-shaped steel beam 1 below the welding layer 5 to receive the welding slag. The receiving hopper 6 is stably mounted on the arc-shaped steel beam 1 by two sets of mounting components 7.

[0036] The mounting assembly 7 includes a mounting rod 72 with an elastic grip tube 71 on a horizontal section. The elastic grip tube 71 is made of elastic rubber material. Extrusion nuts 75 are screwed onto the horizontal sections of the mounting rod 72 on both sides of the elastic grip tube 71. The two extrusion nuts 75 are screwed onto the horizontal sections of the mounting rod 72 and squeeze the elastic grip tube 71 in opposite directions, causing the elastic grip tube 71 to elastically deform.

[0037] The vertical sections at both ends of the mounting rod 72 are screwed with clamping plates 74 through nuts A73. The clamping plates 74 are provided with through holes for the vertical sections of the mounting rod 72 to slide through. The nuts A73 are screwed upward against the clamping plates 74 and pressed tightly against the arc-shaped steel beam 1. The upward extrusion force of the clamping plates 74 against the arc-shaped steel beam 1 and the downward extrusion force of the elastic grip tube 71 that elastically deforms and presses the arc-shaped steel beam 1 downward are clamped on the arc-shaped steel beam 1.

[0038] The bottom end of the mounting rod 72 passes through the through hole provided on the side of the receiving hopper 6, and the bottom end of the mounting rod 72 is clamped to the side of the receiving hopper 6 through two clamping nuts 76, so that the bottom end of the mounting rod 72 and the side of the receiving hopper 6 can be detachably fixed.

[0039] The receiving hopper 6 is clamped and connected to the mounting assembly 7, and the mounting assembly 7 is clamped on the arc-shaped steel beam 1 through the clamping plate 74 and the elastic grip tube 71 for stable installation. When blown by strong winds, the elastic force of the elastic grip tube 71 provides buffering, and the clamping plate 74 and the elastic grip tube 71 clamp the receiving hopper 6 on the arc-shaped steel beam 1 to keep it stable and avoid swinging, solving the problem that the receiving hopper is easily swung and thrown out welding slag when it is suspended by a hanging rope and a hook when the wind is strong.
