Abstract
Description
Technical Field
[0001] This utility model belongs to the field of construction equipment, specifically relating to a sliding device for installing steel beams of large-span skylights on roofs. Background Technology
[0002] In large buildings, roof skylights are often designed with steel structures due to their advantages such as large span, convenient installation, fast construction, and light structural weight. However, the installation of large-span skylight steel beams cannot be carried out as a whole due to the limitations of their location and span. Traditional construction methods often use the scaffolding method, which involves setting up support frames at the segmented locations of the steel beams and hoisting them segment by segment. The limitations of the scaffolding method are: (1) The erection and dismantling of the support frames take up a long time, increasing the construction period. (2) The space below the skylight is mostly an atrium, and the support frame is relatively high, which leads to a significant increase in the cost of the measures. (3) In some cases, the use of tower cranes or large truck cranes is expensive, especially when the skylight steel beams are located in the center of the building, the hoisting operation radius is large, and heavy equipment is required, which further increases the construction cost. Therefore, there is an urgent need to provide a device for the installation of large-span roof skylight steel beams. Utility Model Content

[0023] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below. Technical features in various embodiments of this utility model can be combined appropriately without conflict.
[0024] like Figure 1 As shown in the illustration, this embodiment provides a sliding device for installing steel beams in a large-span roof skylight. The device includes two sliding units for moving the steel beam 4, with one sliding unit at each end of the steel beam 4. The steel beam 4 spans the skylight opening 5, and is transported to the desired installation position via the sliding units at both ends of the steel beam 4.
[0025] like Figure 2 As shown, each sliding unit provided in this embodiment includes a distribution beam 1, a sliding structure 2, and a counterweight 3. Figure 3 As shown, each sliding structure 2 includes a main frame 2-1, connecting rods 2-2, a counterweight platform 2-3, and support rods 2-4, with two main frames 2-1. Each main frame 2-1 is constructed by welding four steel sections into a rectangular frame structure. The main frames 2-1 are arranged in parallel intervals, and four detachable connecting rods 2-2 are vertically arranged between two main frames 2-1. Both ends of each connecting rod 2-2 are detachably connected to the main frame 2-1 by bolts; alternatively, a pin connection can be used by those skilled in the art. Each main frame 2-1 is also equipped with casters at its bottom for easy movement. The casters enable the steel beam to offset and rotate in the plane, avoiding the limitations of traditional sliding tracks.
[0026] In this embodiment, H-beams are used for the main welded frame 2-1, and H-beams are also selected for the connecting rod 2-2. Those skilled in the art can also choose I-beams, square steel pipes, or channel steel according to the actual working conditions.
[0027] In the device provided in this embodiment, a counterweight platform 2-3 for placing the counterweight 3 is provided on one side of the main frame 2-1. The counterweight platform 2-3 is formed by welding several steel sections into a plane for placing the counterweight 3. In this embodiment, four H-beams are used, three of which are arranged in parallel intervals, and the third H-beam is fixed to one end of the three parallel H-beams by welding. The other ends of the three H-beams are fixed to one side of the main frame 2-1 by welding. Since H-beams are used in this embodiment, end connecting plates can be provided at the welding points, and the welding fixation can be completed by end connectors. Those skilled in the art can also choose I-beams, square steel pipes, or channel steel to weld and set the counterweight platform 2-3 according to the actual working conditions. This utility model does not limit the specific setting of the counterweight platform, and those skilled in the art can set it according to the actual required size of the sliding structure 2.
[0028] like Figure 4 As shown, the distribution beam 1 is positioned on top of the sliding structure 2. One end of the distribution beam 1 is detachably connected to the sliding structure 2, and the other end is detachably connected to the steel beam 4. Specifically, the lower flange of the distribution beam 1 is detachably connected to the top of the main frame 2-1 in the sliding structure 2 via several bolts. The other end of the distribution beam 1 is connected to the steel beam 4 via through bolts. Using through bolts to connect to the steel beam to be installed avoids damage to the original structure. Alternatively, those skilled in the art can select other connection methods according to actual working conditions, such as pin connections or bayonet connections.
[0029] In this embodiment, a support rod 2-4 is vertically installed between the counterweight platform 2-3 and the distribution beam 1. Both ends of the support rod 2-4 are connected to the counterweight platform 2-3 and the distribution beam 1 respectively via bolts or pins. To improve the stability of the sliding device during use, a counterweight 3 is placed on the counterweight platform 2-3. In this embodiment, the counterweight 3 is a water-filled counterweight tank. Those skilled in the art can also set different counterweights according to the weight of the steel beam to be transported under actual working conditions to ensure stable transportation of the sliding device.
