Description

Technical Field

[0001] This utility model relates to an installation device for exterior windows of ultra-high-rise curved space frames and a convenient construction platform device, which is mainly used for the installation of exterior windows of ultra-high-rise curved space frames. Background Technology

[0002] Currently, many large factories use steel space frame structures, which are often over 100 meters high. Their exterior windows are generally set at a height of tens of meters. For example, a factory uses a steel space frame structure with a length of 99 meters, a span of 140 meters, and a height of 116 meters. The exterior windows are made of tempered glass, with a maximum installation height of 92 meters and 80% of the installation height between 45 meters and 92 meters.

[0003] When installing high-rise windows, the traditional method is to use a suspended platform + tower crane or a suspended platform + large crane. These methods are generally suitable for installations where the upper part has a fixed suspended platform anchor point and the installation wall is a straight wall. However, these methods are not suitable for installing windows on ultra-high-rise curved space frames (curved space frames cannot accommodate wall ties on tower cranes, and the free height of the tower crane does not exceed 30m). Furthermore, using tower cranes and large cranes results in high construction costs, and because tower crane and large crane operations require specific work areas, it is difficult to implement multiple cranes and multiple work surfaces, leading to low work efficiency. Utility Model Content

[0004] To address the aforementioned shortcomings in existing technologies, this utility model provides a convenient construction platform device for installing exterior windows of ultra-high-rise curved space frames, which features low construction costs, high construction safety, and high applicability.

[0006] When using this utility model for construction, scaffold boards can be erected between the horizontal bars at appropriate positions on the left and right sides of the work basket, according to the needs of the operation. Construction workers stand on the scaffold boards inside the work basket to work, and their hands can extend out of the work basket through the gaps between the horizontal bars on the sides to install the exterior windows, ensuring construction safety. The work basket is hung on the steel structure purlins by hooks and connected to the upper steel structure purlins by lifting straps, providing double fixation and double insurance for the construction platform, resulting in a high safety factor.

[0007] Furthermore, to facilitate the installation of the exterior window and prevent interference, the support legs are correspondingly arranged on both sides of the crossbar of the work basket. The two ends of the crossbar of the work basket extend outwards respectively, and the support legs are connected to the extension of the crossbar.

[0008] Furthermore, to ensure the safety of the construction platform, the hook is connected to the top of the upright, and a reinforcing diagonal brace is provided at the hook.

[0009] Furthermore, the spacing between the horizontal bars on the front and rear vertical sides of the work basket is 500-800mm, the spacing between the horizontal bars on the left and right vertical sides of the work basket is 200-400mm, and the height of the work basket is 2-4m.

[0010] Furthermore, the distance between the front and rear sides of the work basket is 400mm, and the distance between the left and right sides is 2400mm.

[0011] Furthermore, the portable construction platform is made of 40*20*2mm galvanized square tubing.

[0012] This utility model also provides an installation device for the exterior windows of a super high-rise curved space frame, which includes a truck crane and the aforementioned convenient construction platform device for installing the exterior windows of a super high-rise curved space frame. The truck crane is correspondingly set on the ground below the installation position of the exterior window.

[0013] With the cooperation of truck cranes and portable construction platform devices, the installation of exterior windows for ultra-high-rise curved space frames can be carried out conveniently.

[0014] The beneficial effects of this utility model are as follows: The portable construction platform of this utility model has a simple structure and light weight. During construction, it can be hoisted to the construction position for installation by cooperating with a small-tonnage crane. This utility model adopts a double insurance method, hooking the portable construction platform onto the steel structure purlin and connecting it to the steel structure purlin with a hoisting strap. The construction platform is reliably fixed, and the construction safety is high. Construction workers are safer working on the fixed platform, and the construction workers always carry out the window installation work within the work basket, ensuring the safety of the construction operation. This utility model uses a portable construction platform device in conjunction with a small-tonnage truck crane to easily realize the installation of windows on ultra-high-rise curved space frames, which can greatly reduce the use of large-tonnage cranes, reduce construction costs, and enable multiple platforms and multiple work surfaces to be used, resulting in high work efficiency. This utility model effectively solves the problem of installing windows on high-altitude curved space frames. Attached Figure Description

[0022] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings:

[0023] As shown in the attached diagram, a high-rise curved space frame exterior window installation device includes a portable construction platform 1 and a truck crane 3. The portable construction platform 1 is entirely made of 40*20*2mm galvanized square tubing. The portable construction platform 1 includes a rectangular work basket 1.1 welded from four uprights 1.1.3 and several horizontal bars 1.1.4. The work basket 1.1 serves as the work area for construction workers, and its dimensions should be sufficient for workers to stand inside and perform construction work. To ensure the safety of construction workers and facilitate their installation of exterior windows while standing inside the work basket, multiple horizontal bars 1.1.4 are evenly spaced along the height direction on each vertical side of the work basket 1.1, with at least the horizontal bars 1.1.4 on the left and right vertical sides corresponding in the height direction. This facilitates the erection of scaffolding boards between the horizontal bars on the left and right vertical sides. The height of the scaffolding boards can be selected according to construction needs. Multiple horizontal braces 1.1.5 are fixed at intervals between the two horizontal bars 1.1.4 at the bottom of the work basket 1.1. To facilitate window installation work by construction workers standing inside the work basket, preferably, the spacing between the horizontal bars 1.1.4 on the front and rear vertical sides of the work basket 1.1 is 500-800mm, the spacing between the horizontal bars 1.1.4 on the left and right vertical sides is 200-400mm, the spacing between the front and rear sides is 400mm, the spacing between the left and right sides is 2400mm, and the height of the work basket 1.1 is 2-4m. Two symmetrically arranged support legs 1.1.2 are fixedly installed on both sides of the rear side of the work basket 1.1 near the bottom. An inverted L-shaped hook part 1.1.1 is fixedly installed on the top left and right sides of the work basket 1.1, with both the hook parts 1.1.1 and the support legs 1.1.2 located on the rear side of the work basket 1.1. The portable construction platform 1 is connected to the steel purlin 2.1 above the window installation location via its hook 1.1.1 and suspended outside the window installation location. The support leg 1.1.2 is supported on the wall surface of the arc-shaped space frame. The upper end of the portable construction platform 1 is connected to the steel purlin 2.1 above it via a hoisting strap 1.2. The height of the support leg 1.1.2 should ensure sufficient installation and operation space between the work basket and the wall when the support leg is supported on the wall surface of the arc-shaped space frame. The truck crane 3 is a small tonnage crane of 130t or less, and is positioned on the ground below the window installation location.

[0024] To facilitate the installation of the exterior window and prevent interference with the construction platform during installation, in this embodiment, the support leg 1.1.2 is correspondingly arranged on both sides of the horizontal bar near the bottom on the rear side of the work basket 1.1. The two ends of the horizontal bar extend outward by a certain length, and the support leg 1.1.2 is connected to the extension of the horizontal bar.

[0025] To ensure the structural strength of the portable construction platform 1 and the safety of construction, in this embodiment, the hook part 1.1.1 is connected to the top of the upright 1.1.4, and a reinforcing diagonal brace 1.1.6 is provided at the hook part 1.1.1.

[0026] When using this utility model to install exterior windows of a super high-rise curved space frame, a truck crane 3 is first erected on site. The portable construction platform 1 is connected to the crane using a lifting strap. The truck crane 3 lifts the portable construction platform 1 to the construction position. The portable construction platform 1 is then hooked onto the steel purlin 2.1 above the exterior window installation position via its hook part 1.1.1. Personnel then assist in threading the lifting strap 1.2 onto the upper steel purlin 2.1, carefully securing and fixing it a second time to form a "double insurance". After the portable construction platform 1 is installed in place, the truck crane 3 transports the installation materials to the work surface. Workers, wearing double-buckle safety belts inside the work basket, have one end attached to a nearby purlin and the other end attached to a separate safety rope. Then, the workers cooperate with the crane to install the exterior windows. Following a top-down construction sequence, the entire process, including glass frame support installation, glass installation, and sealant application, is carried out within the construction platform's work area. After completing the work in one area, the work is moved to the next area, and so on, until the next area is completed.

[0027] Depending on the site conditions, this utility model can enable multiple units and multiple work surfaces to carry out construction, thereby improving work efficiency.

[0028] The other parts in this embodiment are all existing technologies and will not be described in detail here.
