Description

Technical Field

[0001] This utility model relates to a fixing and tying system for arc-shaped components of steel building structures, belonging to the field of steel structure building construction technology. Background Technology

[0002] When welding outwardly protruding curved steel beams to a steel structure building, the curved steel beams must first be supported at the corresponding height before being welded to the side of the steel structure building.

[0003] The existing steel beam support technology is available in Chinese Patent Publication No. CN112459488A. Although scaffolding can be erected from the ground to support the steel beams, in construction environments with two vertically spaced arc-shaped steel beams, after the construction of the upper arc-shaped steel beam is completed, the scaffolding occupies the space of the lower arc-shaped steel beam. Therefore, the scaffolding must be dismantled before the lower arc-shaped steel beam can be installed, which reduces construction efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fixing and tying system for arc-shaped components of steel building structures.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a fixing and tying system for arc-shaped components of steel structures, comprising:

[0007] A steel structure building in a fixed state, with vertically spaced arc-shaped steel beams on the sides of the steel structure building;

[0008] The upper curved steel beam is supported above the lower curved steel beam by an upper support rod.

[0009] The inner diameter surface of the lower arc-shaped steel beam is fixedly connected to the steel structure building body by a tie rod; one end of the tie rod is fixed to the steel structure building body; the other end of the tie rod is provided with a latch to engage with the vertical reinforcing plate on the lower arc-shaped steel beam.

[0010] The tie rod consists of two spaced-apart rods that connect the lower arc-shaped steel beam to the steel structure for positioning.

[0011] The upper and lower ends of the arc-shaped steel beam are fixedly connected to the sides of the steel structure building by spot welding plates.

[0012] The lower arc-shaped steel beam is supported on the bottom platform by a bottom support rod, which is located at the engagement point between the tie rod and the steel structure.

[0013] The two ends of the upper arc-shaped steel beam are fixed to the sides of the steel structure building through welding layers.

[0014] The arc-shaped steel beam at the weld layer is equipped with a hopper to catch the weld slag.

[0015] The beneficial effects of this utility model are as follows: the two ends of the lower arc-shaped steel beam are spot-welded to the side of the steel structure building through spot welding plates for positioning. At the same time, the lower arc-shaped steel beam is connected to the steel structure building through tie rods and bottom support rods, so that the lower arc-shaped steel beam forms a whole for load-bearing. The upper support rod supports the upper arc-shaped steel beam. After the upper arc-shaped steel beam is welded and fixed to the steel structure building through a welded layer, the lower arc-shaped steel beam can be welded to the steel structure building immediately. This solves the problem that the arc-shaped steel beam supported by the scaffolding erected on the ground needs to be disassembled before the lower arc-shaped steel beam can be installed, thus improving construction efficiency.

Detailed Implementation

[0021] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0022] like Figures 1 to 4 As shown.

[0023] This application discloses a fixing and tying system for arc-shaped components of steel structures, comprising:

[0024] The steel structure building 9 is fixed on the ground foundation. The steel structure building 9 has vertically spaced arc-shaped steel beams 1 on its sides.

[0025] The inner diameter surface of the lower arc-shaped steel beam 1 is fixedly connected to the steel structure 9 via tie rods 11; one end of the tie rod 11 is welded to the steel structure 9; the other end of the tie rod 11 is provided with a latch 12 to engage with the vertical reinforcing plate 13 on the lower arc-shaped steel beam 1, and the vertical reinforcing plate 13 is a component that is fixedly attached to the arc-shaped steel beam 1 itself; the tie rods 11 are two spaced-apart rods that tie the lower arc-shaped steel beam 1 to the steel structure 9 for limiting its position.

[0026] The upper and lower ends of the arc-shaped steel beam 1 are fixedly connected to the sides of the steel structure building 9 by spot welding through spot welding plates 14.

[0027] The lower arc-shaped steel beam 1 is supported on the bottom platform 3 by the bottom support rod 2. The bottom support rod 2 is located at the engagement point between the tie rod 11 and the steel structure 9. The lower arc-shaped steel beam 1 and the bottom support rod 2 are fixed together by bolts.

[0028] The upper arc-shaped steel beam 1 is supported above the lower arc-shaped steel beam 1 by the upper support rod 4, and the two ends of the upper arc-shaped steel beam 1 are fixed to the sides of the steel structure building 9 by the welding layer 5.

[0029] A clamping and stable receiving hopper 6 is installed on the arc-shaped steel beam 1 located at the welding layer 5.

[0030] The lower curved steel beam 1 is spot-welded to the sides of the steel structure 9 at both ends via spot-welded plates 14. It is simultaneously connected to the load-bearing structure by tie rods 11 and supported by the bottom support rod 2, forming a unified load-bearing structure. The upper support rod 4 then supports the upper curved steel beam 1. After the upper curved steel beam 1 is welded to the steel structure 9 via a weld layer 5, the lower curved steel beam 1 can be welded to the steel structure 9. This solves the problem of having to disassemble the scaffolding erected from the ground to support the upper curved steel beam before installing the lower curved steel beam, thus improving construction efficiency. After welding the lower curved steel beam 1, the upper support rod 4, bottom support rod 2, and tie rod 11 are disassembled. The upper support rod 4 is detachably fixed to the upper and lower curved steel beams 1 using bolts and nuts, and the bottom support rod 2 is detachably fixed to the lower curved steel beam 1 using bolts and nuts.

[0031] This application discloses a construction method for connecting arc-shaped components in steel structures, comprising:

[0032] The lower arc-shaped steel beam 1 serves as the load-bearing whole to support the upper arc-shaped steel beam 1, thus presenting the construction process of the fixed connection system of the arc-shaped steel structure.

[0033] Steel structure buildings are constructed by welding multiple components. When arc-shaped steel beams are welded on the side of the steel structure building, the welding slag produced by welding, carrying high temperature, falls and affects the installation work of personnel in the construction environment below. Therefore, a slag catcher is needed to catch the welding slag.

[0034] The existing slag catcher is shown in Chinese Patent Publication No. CN208961281U. Although the hopper can be suspended by a rope and a hook, the strong winds in coastal and high-altitude environments can easily cause the hopper to swing on the hook and throw out welding slag.

[0035] This application discloses a slag catcher for welding, comprising:

[0036] A receiving hopper 6 is installed on the curved steel beam 1, below the welding layer 5, to catch welding slag. The receiving hopper 6 is securely mounted on the curved steel beam 1 by two sets of mounting components 7.

[0037] The mounting assembly 7 includes a mounting rod 72 with an elastic grip 71 sleeved on a horizontal section. The elastic grip 71 is made of elastic rubber material. The horizontal sections of the mounting rod 72 located on both sides of the elastic grip 71 are screwed with compression nuts 75. The two compression nuts 75 are screwed onto the horizontal sections of the mounting rod 72 and move towards each other to compress the elastic grip 71, causing the elastic grip 71 to undergo elastic deformation.

[0038] The vertical sections at both ends of the mounting rod 72 are screwed with clamping plates 74 by 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 onto the clamping plates 74 and pressed against the arc-shaped steel beam 1. The upward pressing force of the clamping plates 74 against the arc-shaped steel beam 1 and the downward pressing force of the elastic gripping cylinder 71 against the arc-shaped steel beam 1 are used to clamp the rod onto the arc-shaped steel beam 1.

[0039] The bottom end of the mounting rod 72 passes through the through hole provided on the side of the receiving hopper 6. The bottom end of the mounting rod 72 is clamped to the side of the receiving hopper 6 by two clamping nuts 76, so that the bottom end of the mounting rod 72 can be detachably fixed to the side of the receiving hopper 6.

[0040] The receiving hopper 6 is clamped to the mounting component 7. The mounting component 7 is clamped to the arc-shaped steel beam 1 by the clamping plate 74 and the elastic grip 71 for stable installation. When blown by strong wind, the elastic force of the elastic grip 71 provides cushioning. The clamping plate 74 and the elastic grip 71 clamp the receiving hopper 6 to the arc-shaped steel beam 1 to keep it stable and prevent it from swinging. This solves the problem that the receiving hopper is easy to swing and throw out welding slag when suspended by the hanging rope and hook in strong wind.
