Description

Technical Field

[0001] The invention relates to the technical field of industrial plant steel structures, and in particular to a method for online rapid installation of a steel structure plant wall system. Background Art

[0002] At present, there are two main methods for installing the wall system of steel structure workshops: one is to install the wall column → purlin → other components one by one; the other is to install the wall column first, and then form the purlin into a small local whole for hoisting.

[0003] During the online technical transformation of metallurgical plants, the installation time in the plant needs to be shortened as much as possible due to the high risks of construction caused by production and the high risks of working at heights. Summary of the invention

[0004] The purpose of the present invention is to solve the problems raised in the above-mentioned background technology. The present invention provides a method for online rapid installation of a steel structure factory wall system, which greatly reduces online operation time and reduces safety risks.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] A method for online rapid installation of a steel structure factory wall system comprises the following steps:

[0007] (1) Determine the ground pre-assembly site and build a simple assembly platform with pipes or profiles according to the on-site material conditions;

[0008] (2) Draw the wall column positioning line on the assembly platform, and place the three wall columns at the corresponding positions on the platform, with the purlin installation part facing upwards;

[0009] (3) Install wall purlins;

[0010] (4) Install straight braces and diagonal braces between purlins;

[0011] (5) Install the pipe bracket on the inner side of the wall column and fix the pipe on the bracket with pipe clamps;

[0012] (6) Temporary lifting holes are set at the upper and lower ends of the wall column;

[0013] (7) Use two cranes to turn over and hoist the entire wall system, and use balance beams at both ends for hoisting;

[0014] (8) Overall lifting.

[0015] In step (1), an assembly platform is laid and leveled using H-shaped steel. The platform length = the distance between 3 wall columns + 2m, and the width = the length of the wall columns - 6m.

[0016] In step (8), the main crane lifts the hook, and the auxiliary hook cooperates in the lifting, keeping the lower end of the wall column at a height of 0.5m from the ground; when the angle between the component and the ground is 75°, the main hook is kept stationary, and the auxiliary hook is unhooked after placing the lower end of the component on the ground.

[0017] When the auxiliary hook places the lower end of the component on the ground and then removes the hook, continue to use the main hook to lift the component to the installation position and fix it, and then install the wall tiles.

[0018] Beneficial effects:

[0019] The wall system of the present invention is installed on the ground, changing the original high-altitude vertical operation to the ground horizontal operation, thereby reducing the time and risk of high-altitude construction and making it easier to ensure the installation quality.

[0020] The present invention reduces the operation time near the dangerous production environment and can effectively ensure the safety of personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] The present invention discloses a method for online rapid installation of a steel structure factory building wall system, comprising the following steps:

[0026] (1) Determine the ground pre-assembly site and build a simple assembly platform with pipes or profiles according to the on-site material conditions;

[0027] (2) Draw the positioning line of the wall skin column 2 on the assembly platform, and place the three wall skin columns 2 at the corresponding positions on the platform, with the purlin installation part facing upwards;

[0028] (3) Install wall purlins;

[0029] (4) Install the straight braces and diagonal braces between the purlins; the straight braces and diagonal braces between the purlins here constitute the purlin system 3.

[0030] (5) Install the pipe bracket on the inner side of the wall column and fix the pipe on the bracket with pipe clamps to form a stable pipe system 7; of course, other fixing methods can also be used to fix the pipe.

[0031] (6) Temporary lifting holes are set at the upper and lower ends of the wall column;

[0032] (7) Two cranes are used to turn over and hoist the entire wall system. During the hoisting, balance beams 5 are used for hoisting at both the upper and lower ends; the balance beams 5 use steel wire ropes 4 to hoist the wall columns 2.

[0033] (8) Overall lifting.

[0034] In step (1), an assembly platform is laid and leveled with H-shaped steel 1. The platform length = the distance between 3 wall skin columns + 2m, and the width = the length of wall skin column 2 - 6m. The width can be adjusted according to the actual situation. Here, the distance between the 3 wall skin columns refers to Figure 1 The distance between the two farthest wall columns.

[0035] In step (8), the main hoist 6 lifts the hook, and the auxiliary hook 8 cooperates in the lifting, keeping the lower end of the wall column at a height of about 0.5m from the ground; when the angle between the component and the ground is about 75°, the main hook 6 is kept stationary, and the auxiliary hook 8 places the lower end of the component on the ground and then removes the hook.

[0036] When the auxiliary hook places the lower end of the component on the ground and then removes the hook, the main hook 6 is continued to be used for hoisting, and the component is hoisted to the installation position for fixing, and then the wall tile is installed.

[0037] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
