Description

Technical Field

[0001] The invention relates to a connection construction method for arc parts of a steel building body, belonging to the technical field of steel structure building body construction. Background Art

[0002] When welding an outwardly cantilevered curved steel beam of a steel structure building, the curved steel beam must first be supported at a corresponding height and then welded to the side of the steel structure building.

[0003] The existing steel beam support technology is shown in Chinese Patent Publication No. CN112459488A. Although a scaffold can be set up on the ground to support the steel beam, for a construction environment with two vertically spaced arc-shaped steel beams, after the scaffold is set up on the ground to support the upper arc-shaped steel beam, the scaffold occupies the space of the lower arc-shaped steel beam, so the scaffold needs to be dismantled before the lower arc-shaped steel beam can be installed for construction, which reduces the construction efficiency. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a connection construction method for arc parts of a steel building body.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a method for connecting and constructing circular arc parts of a steel building, comprising:

[0007] The lower arc-shaped steel beam is used as a load-bearing whole to support the upper arc-shaped steel beam, thereby presenting the construction process of the fixed tie system of the circular arc parts of the steel building body.

[0008] The fixing and fastening system of the arc parts of the steel building body comprises:

[0009] A steel structure building body in a fixed state, with arc-shaped steel beams distributed vertically at intervals on the side of the steel structure building body;

[0010] The upper arc-shaped steel beam member is supported above the lower arc-shaped steel beam member through an upper support rod.

[0011] The inner diameter surface of the arc-shaped steel beam at the bottom is fixedly connected to the steel structure building body through 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 bayonet to engage with the vertical reinforcement plate on the arc-shaped steel beam at the bottom.

[0012] The pull rods are two rods distributed at intervals to tie the lower arc-shaped steel beam to the steel structure building body for positioning.

[0013] The upper and lower surfaces at both ends of the arc-shaped steel beam member at the bottom are spot-welded, positioned and fixedly connected to the side of the steel structure building body through spot welding plates.

[0014] The arc-shaped steel beam member at the bottom is supported on the bottom platform by a bottom support rod, and the bottom support rod is located at the corresponding engagement position between the pull rod and the steel structure building body.

[0015] The two ends of the upper arc-shaped steel beam are fixed to the side of the steel structure building body through a welding layer.

[0016] A receiving hopper for receiving welding slag is installed on the arc-shaped steel beam member at the welding layer.

[0017] The beneficial effects of the present invention are as follows: the two ends of the lower arc-shaped steel beam are spot-welded and positioned with the side of the steel structure building body through spot welding plates, and at the same time, the arc-shaped steel beam below is formed into a force-bearing whole through the tension rod tensioning and the support of the bottom support rod to install the upper support rod supporting the arc-shaped steel beam above. After the upper arc-shaped steel beam is welded and fixed to the steel structure building body through the welding layer, the lower arc-shaped steel beam can be welded to the steel structure building body immediately, which solves the problem that the scaffolding erected from the ground to support the upper arc-shaped steel beam needs to be dismantled before the lower arc-shaped steel beam can be installed, thereby improving construction efficiency.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0024] like Figures 1 to 4 shown.

[0025] The present application discloses a steel building body arc member fixing and fastening system, comprising:

[0026] A steel structure building body 9 is constructed and fixed on a ground foundation, and arc-shaped steel beams 1 are vertically spaced and distributed on the sides of the steel structure building body 9.

[0027] The inner diameter surface of the arc-shaped steel beam 1 at the bottom 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 a vertical reinforcement plate 13 on the arc-shaped steel beam 1 below, and the vertical reinforcement plate 13 is a component fixed to the arc-shaped steel beam 1 itself; the tie rods 11 are two spaced-apart tie rods 11 which tie the arc-shaped steel beam 1 below to the steel structure building body 9 for position limiting.

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

[0029] The arc-shaped steel beam 1 at the bottom is supported on the bottom platform 3 by the bottom support rod 2, and the bottom support rod 2 corresponds to the engagement position between the pull rod 11 and the steel structure building body 9, and the arc-shaped steel beam 1 at the bottom is fixed to the bottom support rod 2 by bolts.

[0030] The arc-shaped steel beam member 1 at the top is supported on the top of the arc-shaped steel beam member 1 at the bottom through the upper support rod 4 , and both ends of the arc-shaped steel beam member 1 at the top are fixed to the side of the steel structure building body 9 through the welding layer 5 .

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

[0032] The two ends of the arc-shaped steel beam 1 at the bottom are spot-welded and positioned with the side of the steel structure building body 9 through the spot welding plate 14, and at the same time, the tension rod 11 is used to pull the force and the bottom support rod 2 to support the arc-shaped steel beam 1 at the bottom to form a force-bearing whole to install the upper support rod 4 to support the arc-shaped steel beam 1 at the top. After the arc-shaped steel beam 1 at the top is welded and fixed with the steel structure building body 9 through the welding layer 5, the arc-shaped steel beam 1 at the bottom can be welded with the steel structure building body 9 immediately, which solves the problem that the arc-shaped steel beam 1 at the bottom needs to be disassembled after the construction of the scaffolding supporting the arc-shaped steel beam at the top is erected from the ground, thereby improving the construction efficiency. After the arc-shaped steel beam 1 at the bottom is welded, 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 removably fixed with the arc-shaped steel beam 1 at the top and bottom through bolts and nuts, and when the bottom support rod 2 is installed, it is removably fixed with the arc-shaped steel beam 1 at the bottom through bolts and nuts.

[0033] The present invention provides a method for connecting and constructing arc parts of a steel building, comprising:

[0034] The lower arc-shaped steel beam member 1 is used as a force-bearing whole to support the upper arc-shaped steel beam member 1, thereby presenting the construction process of the fixed tie system of the circular arc member of the steel building body.

[0035] 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.

[0036] 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.

[0037] A slag collector for welding of the present application comprises:

[0038] A receiving hopper 6 is installed on the arc-shaped steel beam 1 below the welding layer 5 to receive the welding slag. The receiving hopper 6 is clamped and stably installed on the arc-shaped steel beam 1 by two sets of mounting components 7.

[0039] The mounting assembly 7 comprises a mounting rod 72 with an elastic gripping tube 71 on a horizontal section, wherein the elastic gripping tube 71 is made of elastic rubber material, and the horizontal sections of the mounting rod 72 on both sides of the elastic gripping tube 71 are screwed with extrusion nuts 75, and the two extrusion nuts 75 are screwed on the horizontal sections of the mounting rod 72 to squeeze the elastic gripping tube 71 in opposite directions, so that the elastic gripping tube 71 undergoes elastic deformation;

[0040] The vertical sections at both ends of the mounting rod 72 are screwed with a clamping plate 74 through a nut A73. The clamping plate 74 is provided with a through hole for the vertical section of the mounting rod 72 to slide through. The nut A73 is screwed on the clamping plate 74 and pressed against the arc-shaped steel beam 1. The upward extrusion force of the clamping plate 74 pressing against the arc-shaped steel beam 1 and the downward extrusion force of the elastic grip tube 71 pressing against the arc-shaped steel beam 1 are clamped on the arc-shaped steel beam 1.

[0041] The bottom end of the mounting rod 72 passes through a 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 by 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.

[0042] The material receiving hopper 6 is clamped and connected to the installation component 7, and the installation component 7 is clamped and stably installed on the arc-shaped steel beam 1 through the clamping plate 74 and the elastic gripping tube 71. When blown by strong winds, the elastic force of the elastic gripping tube 71 provides buffering, and the clamping plate 74 and the elastic gripping tube 71 clamp the material receiving hopper 6 on the arc-shaped steel beam 1 to keep it stable and avoid swinging, thereby solving the problem that the material 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.
