Abstract
Description
Technical Field
[0001] This utility model relates to an installation method, and in particular to an installation structure for purlins on the walls of steel structure factory buildings. Background Technology
[0002] Currently, steel structures are widely used in industrial plants due to their fast construction speed, high recyclability, and ease of maintenance. Industrial plants typically have high ceilings, large floor areas, and long exterior walls, resulting in numerous purlins and complex installation processes. Cranes are generally used for purlin installation, but each purlin requires individual hoisting and securing. The lifting and rotation of the hoisting equipment consumes considerable time, leading to low construction efficiency, especially for large wall areas. Improving installation speed requires investing in more hoisting equipment, increasing costs. Furthermore, the use of large hoisting equipment also increases safety risks during construction. Summary of the Invention
[0003] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a safe and reliable method for installing purlins on large-area steel structure walls.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] This utility model discloses a steel structure wall purlin installation structure, comprising multiple steel columns spaced laterally along the length of the wall panel to be installed. Each vertically arranged steel column has its top fixedly connected to a roof beam and its bottom fixedly connected to a ground foundation. Purlin supports are horizontally arranged on the outer flange plates at the lower part of the multiple steel columns. Fixed supports are installed at the same height at the bottom of each steel column, and a synchronous lifting motor is installed on each fixed support. A bracket is fixed to the top of each steel column, and a fixed pulley is fixed to the outside of the bracket.
[0006] The synchronous lifting motors at two adjacent steel columns form a lifting structure. Each lifting structure is used to lift the purlin to be installed. The shafts of the two synchronous lifting motors in each lifting structure are fixedly connected to one end of a steel wire rope. The other end of each steel wire rope is led upward, passes over the fixed pulley on the corresponding steel column, and then descends to the position of the purlin to be installed on the ground. The two steel wire ropes are fixed to the left and right ends of the purlin to be installed by buckles. A guide rope is tied to the purlin.
[0007] The beneficial effects of this utility model are:
[0008] (1) This utility model replaces the crane with a synchronous lifting motor as the lifting device for purlin installation, thereby avoiding the use of large equipment and reducing the safety risks in the hoisting of large equipment.
[0009] (2) The bottom of the steel columns on both sides of this utility model adopts a synchronous lifting motor, which avoids the problem that the purlin cannot be kept horizontal during the rise due to the difference in lifting speed on both sides.
[0010] (3) This utility model is simple to manufacture. The top support and synchronous lifting motor can be reused, avoiding the problem of material waste caused by one-time material input and saving materials.
[0011] (4) The present invention provides a guide rope in the purlin lifting process, which can effectively control the stability of the purlin during installation.
[0012] (5) This utility model has a simple structure and can realize the rapid installation of purlins, thereby improving construction efficiency.
[0013] (6) Steel structure is widely used in factory buildings. Generally, the factory area is large, so this utility model has a wide range of applications and is easy to promote. Attached Figure Description

[0015] Figure 2 This is a front view of a purlin installation structure for steel structure walls according to this utility model. Detailed Implementation
[0016] The utility model will now be described in further detail with reference to the accompanying drawings and specific examples.
[0017] like Figure 1 As shown, this utility model discloses a steel structure wall purlin installation structure, comprising multiple steel columns 7 spaced laterally along the length of the wall panel to be installed. The top of each vertically arranged steel column is fixedly connected to a roof beam, and its bottom is fixedly connected to a ground foundation. Purlin supports are horizontally arranged on the outer flange plates at the lower part of the multiple steel columns 7.
[0018] Fixed supports 2 are installed at the same height at the bottom of each steel column 7. Preferably, the fixed supports 2 are angle steel and are bolted to the purlins on the steel column 7. A synchronous lifting motor 1 is installed on each fixed support 2. A bracket 8 is fixed at the top of each steel column 7. Preferably, the bracket 8 is made of structural steel. A fixed pulley 5 is fixed to the outside of the bracket 8.
[0019] The synchronous lifting motors at the two adjacent steel columns form a lifting structure. Each lifting structure is used to lift the purlin to be installed. The shafts of the two synchronous lifting motors in each lifting structure are fixedly connected to one end of a steel wire rope 3. The other end of each steel wire rope is led upward, passes over the fixed pulley 5 on the corresponding steel column, and then descends to the position of the purlin 6 to be installed placed on the ground. The two steel wire ropes 3 are fixed to the left and right ends of the purlin 6 to be installed by buckles respectively. A guide rope 4 is tied to the purlin 6.
[0020] like Figure 2 As shown, during installation, the synchronous lifting motors 1 on both sides operate to tighten the wire rope 3, and the wire rope 3, which passes over the fixed pulley 5, lifts the purlin 6 to the installation height. At the same time, the guide rope 4 fixed on the purlin 6 is used to control the posture of the purlin 6 during the lifting process to ensure that it does not collide with the steel column 7.
[0021] After the purlin 6 is raised to the set position, it is fixed to the steel column and installed in sequence until the installation of this span is completed, and then moved to another span for the same installation.
[0022] The above-described specific embodiments are merely illustrative and not restrictive. Those skilled in the art can make many modifications under the guidance of this utility model without departing from the spirit and scope of the claims, and these modifications are all protected by this utility model.
